Turin Shroud ‘was created by flash of supernatural light’

It couldn’t be a medieval forgery, say scientists

Turin Shroud

The image on the Turin Shroud could not be the  work of medieval forgers but was instead caused by a supernatural ‘flash of light’, according to scientists.

Italian researchers have found evidence that casts doubt on claims that the relic – said to be the burial cloth of Jesus – is a fake and they suggest that it could, after all, be authentic.

Sceptics have long argued that the shroud, a rectangular sheet measuring about 14ft by 3ft, is a forgery dating to medieval times.

Scientists from Italy’s National Agency for New Technologies, Energy and Sustainable Economic Development spent years trying to replicate the shroud’s markings.

They have concluded only something akin to ultraviolet lasers – far beyond the capability of medieval forgers – could have created them.

This has led to fresh suggestions that the imprint was indeed created by a huge burst of energy accompanying the Resurrection of Christ.

‘The results show a short and intense burst of UV directional radiation can colour a linen cloth so as to reproduce many of the peculiar characteristics of the body image on the Shroud of Turin,’ the scientists said.

WHAT IS THE TURIN SHROUD?

The Vatican owns the Turin shroud, and hails the relic as an exploration of the ‘darkest mystery of faith’.

But the church has shied away from any definitive statement over whether the shroud – which is supposed to have formed Christ’s burial robe – is real.

The Shroud is thought to have travelled widely before it was brought to France in the 14th century by a Crusader.

It was kept in a French convent for years – by nuns who patched it, and where it was damaged by fire.

The Shroud was given to the Turin Archbishop in 1578 by the Duke of Savoy and has been kept in the Cathedral ever since.

Carbon dating tests in 1988 dated it from between 1260 and 1390 – implying it was a fake.

Scientists have since claimed that contamination over the ages from patches, water damage and fire, was not taken sufficiently into account In 1999, two Israeli scientists said plant pollen found on the Shroud supported the view that it comes from the Holy Land.

There have been numerous calls for further testing but the Vatican has always refused.

The image of the bearded man on the shroud must therefore have been created by ‘some form of electromagnetic energy (such as a flash of light at short wavelength)’, their report concludes. But it stops short of offering a non-scientific explanation.

Professor Paolo Di Lazzaro, who led the study, said: ‘When one talks about a flash of light being able to colour a piece of linen in the same way as the shroud, discussion inevitably touches on things such as miracles.

‘But as scientists, we were concerned only with verifiable scientific processes. We hope our results can open up a philosophical and theological debate.’
For centuries, people have argued about the authenticity of the shroud, which is kept in a climate-controlled case in Turin cathedral.

One of the most controversial relics in the Christian world, it bears the faint image of a man whose body appears to have nail wounds to the wrists and feet.

Some believe it to be a physical link to Jesus of Nazareth. For others, however, it is nothing more than an elaborate forgery.

In 1988, radiocarbon tests on samples of the shroud at the University of Oxford, the University of

Arizona, and the Swiss Federal Institute of Technology dated the cloth to the Middle Ages, between 1260 and 1390.

Those tests have been disputed on the basis that they were contaminated by fibres from cloth used to repair the shroud when it was damaged by fire in the Middle Ages.

More recently, further doubt was cast on its authenticity when Israeli archaeologists uncovered the first known burial shroud in Jerusalem from the time of the Crucifixion.

Its weave and design are completely different from the Turin Shroud, they said.

The Jerusalem shroud has a simple two-way weave – but the twill weave used on the Turin Shroud was introduced more than 1,000 years after Christ lived.

Mexico to cash in on 2012 Mayan end of the world apocalypse prophecy

By Nick Allen

2012 Mayan end of the world

2012 Mayan end of the world

Mexico is planning to capitalize on predictions of an apocalypse next year by encouraging a tourism boom in areas occupied by the ancient Mayans.

Inscriptions found on two Mayan tablets have been interpreted by some as heralding a cataclysmic event on Dec 21, 2012.

The country’s tourism agency, which stressed it does not itself believe the world will end, hopes to attract 52 million visitors to southeastern areas that were the heart of Mayan territory over the course of next year. The whole of the country usually attracts 22 million visitors annually.

More than 500 Mayan-themed events have been planned including ceremonies with Mayan priests performing rituals, burning incense and chanting.

In the jungle near Cancun messages and photographs will be placed in a “time capsule” and buried.

The town of Chiapas, on the Guatemalan border, is installing an 8ft digital clock in its main park which will count down to the much anticipated date.

 

Experts including archaeologists at Mexico’s National Institute of Anthropology say Mayan thinking has been misinterpreted and the world will not end. They say the Maya saw time as a series of cycles and 2012 merely marks the end of one of those cycles.

But suggestions of an apocalypse have been fuelled by the Hollywood blockbuster film “2012,” which in turn has helped Mexico become more intriguing for tourists.

Yeanet Zaldo, a tourism spokeswoman for the state of Quintana Roo, which includes Cancun, said: “People who still live in Mayan villages will host rites and burn incense for us to go back in time and try to understand the Mayan wisdom.”

The Mayan calendar begins in 3,114BC and splits time into 394-year periods known as Baktuns. The 13th Baktun ends around Dec 21, 2012.

According to a 1,300-year-old stone tablet Bolon Yokte, a Mayan god associated with both war and creation, will “descend from the sky” at that time.

Archaeologists revealed recently that they had found a second possible reference to the date on a brick fragment.

But Miss Zaldo said she was confident tourism would continue into 2013. She said: “The world will not end. It is an era.”

The Chinese solar machine

China’s production of solar cells is far outpacing everyone else’s (credit: GTM research)

Chinese manufacturers make about 50 million solar panels a year — over half the world’s supply in 2010 — and include four of the world’s top five solar-panel manufacturers.

The industry elsewhere has been doubling in size every two years, and Chinese manufacturers have done even better, doubling their production roughly every year.

They have succeeded in large part because it’s faster and cheaper for them to build factories, thanks to inexpensive, efficient construction crews and China’s streamlined permitting process. The new factories have the latest, most efficient equipment, which helps cut costs. So do the efficiencies that come with size.

From now on, the best way for Chinese manufacturers to lower the cost per watt of solar power may not be by lowering manufacturing costs but, instead, by increasing the number of watts each panel generates.

In 2010, when the U.S. secretary of energy, Steven Chu, gave a speech to the National Press Club laying out his case that the United States was falling behind in advanced manufacturing, Suntech Power was his Exhibit A. He had toured its factory, and he was impressed by what he’d seen. “It’s a high-tech, automated factory,” he said. “It’s not succeeding because of cheap labor.” Not only that, he noted, but Suntech had developed a type of solar cell with world-record efficiencies.

Solar flares (credit: SOHO/NASA/ESA)

Piet Martens of Montana State University and colleagues have developed 15 programs that use data from NASA’s Solar Dynamics Observatory (SDO) and image-processing techniques such as contour or edge recognition to automatically identify features on the sun’s surface.

To make the process generic, Martens’ team is using techniques developed to identify breast tumors. This involves splitting a 1.6-million-pixel image into 1024 blocks. For each block, the software calculates the values for various mathematical parameters, such as the entropy (a measure of the chaos in the image).

This turns the image into a series of numbers. In breast imaging, this technique highlights regions of breast tissue with specific values that are known to be characteristic of tumors. Martens’s team is doing this with SDO images, training the software to learn the defining characteristics of sunspots, filaments and other solar features.

Each program is looking for a different aspect of solar activity. This include flares and CMEs, as well as other features that might indicate that flares or eruptions are imminent, such as filaments, which are bundles of plasma held down by magnetic field lines, coronal loops and sunspots.

Solar storms can wreak havoc on Earth, but if we can predict them, vital infrastructure could be saved.

A super-memory smart drug?

suppressionofpkr

suppressionofpkr

Could this be the “Limitless” breakthrough we’ve been looking for?

Researchers at Baylor College of Medicine  (BCM) have discovered that when the activity of PKR — a molecule normally elevated during viral infections — is inhibited in the brain, mice learn and remember dramatically better.

“The molecule PKR (the double-stranded RNA-activated protein kinase) was originally described as a sensor of viral infections, but its function in the brain was totally unknown,” said Dr. Mauro Costa-Mattioli, assistant professor of neuroscience at BCM. But the activity of PKR is altered in a variety of cognitive disorders, so Costa-Mattioli and colleagues decided to take a closer look.

Super memory

“We found that when we genetically inhibited PKR, we increased the excitability of brain cells and enhanced learning and memory in a variety of behavioral tests,” said Costa-Mattioli.

For instance, they tested the mice ability to use visual cues for finding a hidden platform in a circular pool. Normal mice had to repeat the task multiple times over many days to remember the platform’s location. Mice lacking PKR learned the task after only one training session.

Memory-enhancing drug

The BCM researchers also found that this process could be mimicked by a PKR inhibitor — a small molecule that blocks PKR activity and thus acts as a “memory-enhancing drug.” The next step is to use what we have learned in mice and to try to improve brain function in people suffering from memory loss, said Costa-Mattioli.

There are roughly 6 million Americans and 35 million people world-wide with Alzheimer’s disease and more than 70 million Americans over the age of 60 who may suffer from aged-associated impairment of memory. (Not counting the millions who just want to be smarter, which would be just about everybody.)

Unfortunately, there’s a secret government conspiracy to keep this drug out of your hands. OK, I made that part up.

But note the figure above: in mice that have been genetically engineering to inhibit PKR (right), the result is to lower GABA release. We know that GABA, the brain’s major inhibitory neurotransmitter, has an anti-anxiety or calming effect, which is why tranquilizers increase GABA production. So could using the PKR inhibitor drug also lead to increased anxiety?

Also, PKR is not just elevated during viral infections. PKR is thought to be a key player in cellular response to different kinds of stress: PKR activation leads to inhibited protein synthesis and transcription of genes involved in an inflammatory response. So you get smarter, but also get sicker if you have the flu or some other stressor? Or maybe just take it when you’re not under stress?

I have an email into Dr. Costa-Mattioli find out more.

Google’s Majel Voice Recognition Technology

Google's Majel

Google's Majel

A couple days ago we posted about Majel, and now some more tips are starting to come in. We compared Majel to Apple’s Siri voice assistant because that’s how it was described to us, but the project could be much larger than we initially imagined. Read on for new details and some interesting quotes from Google employees.

First we had a tip from “Ted,” who described his experience with an early release of Majel on an Android tablet. Even though this tip was sent from an anonymous IP, we believe it to be accurate since it matched an earlier description we received.

Ted wrote: “It’s definitely as good, or better, than Siri. At least on the tablet you can sort through different answers with these swipe-able trays. Like, if you say “show me the Statue of Liberty” it’ll automatically take you to Google Image results, but another tray beneath it might be its location on Google Maps and then another tray might have a Wikipedia page. It’s also pretty good at giving you succinct answers if you ask it a question. The UI is definitely more powerful than Siri’s, even if a little harder to navigate.

At least at one phase of the development you would activate it by saying “Computer…” It was hard not to use a Jean Luc Piccard accent when doing it!”

As you can see, the first release of Majel might be rather simple and focus solely on natural language questions with answers from Google Search.

Next up we have some comments posted to Reddit from an ex-employee of Google who claims to have worked at the secret Google X Lab.

The anonymous Googler wrote: “This is in total violation of the NDA, but I don’t care anymore. Sue me.

The central focus of Google X for the past few years has been a highly advanced artificial intelligence robot that leverages the underlying technology of many popular Google programs. As of October (the last time I was around the project), the artificial intelligence had passed the Turing Test 93% of the time via an hour long IM style conversation. IM was chosen to isolate the AI from the speech synthesizer and physical packaging of the robot.

The robot itself isn’t particularly advanced because the focus was not on mechanics, but rather the software. It is basically a robotish looking thing on wheels. Speech recognition is somewhat better than what you would get with normal speech input, mostly because of the use of high quality microphones and lip-reading assistance.

I have had the chance to interact with the robot personally and it is honestly the most amazing thing that I have ever seen. I like to think of it like Stephen Hawking because it is extremely smart and you can interact with it naturally, but it is incapable of physically doing much. There is a planned phase two for development of an advanced robotics platform.

This sounds more along the lines of the shoot-for-the-stars ideas that the NYTimesdescribed when they wrote about Google X. Obviously, Google has been working on artificial intelligence for many years.

Moving along, we return to some comments from Mike Cohen, Google’s Manager of Speech Technology and co-founder of Nuance Communications (the company that powers some of the technology behind Siri).

Google's federation computer

Google's federation computer

Mike Cohen wrote: “In Star Trek, they don’t spend a lot of time typing things on keyboards—they just speak to their computers, and the computers speak back. It’s a more natural way to communicate, but getting there requires chipping away at a range of hard research problems.

We’ve recently made some strides with speech technologies and tools that take voice input. But what about when the computer speaks to you—in other words, voice output?

That’s why we’re pleased to announce we’ve acquired Phonetic Arts, a speech synthesis company based in Cambridge, England. Phonetic Arts’ team of researchers and engineers work at the cutting edge of speech synthesis, delivering technology that generates natural computer speech from small samples of recorded voice.

We are excited about their technology, and while we don’t have plans to share yet, we’re confident that together we’ll move a little faster towards that Star Trek future.”

Many readers joked in the comments of our previous article that they wish Majel Barrett-Roddenberry’s voice could be used for Google’s project, and it turns out they have the technology to do it. They would still need to license the rights to Majel’s voice samples, but Google could essentially replicate any voice they want.

Keeping with the Star Trek theme, we have more comments from Google’s Amit Singhal found in The Evolution of search video posted in November.

Amit Singhal says: “My dream has always been to build the Star Trek computer, and in my ideal world, I would be able to walk up to a computer, and say, ‘Hey, what is the best time for me to sow seeds in India, given that monsoon was early this year?’ And once we can answer that question (which we don’t today), people will be looking for answers to even more complex questions. These are all genuine information needs. Genuine questions that if we – Google – can answer, our users will become more knowledgeable and they will be more satisfied in their quest for knowledge.”

Finally, we have the comments of Matias Duarte, the computer-interface designer and user-experience lead for Android,  from an interview with The Daily Beast.

Matias Duarte said: “Voice is absolutely going to be an essential part of user interfaces. I mean Google and Android have been working on Voice for years. Even in Ice Cream Sandwich we released significant improvements to the way Voice dication works. What I think is going to be interesting about Voice is trying to treat Voice as something that is universally accessible in every application and not confine it to just a gimmick or something you only use when you are in the car or on the go.

I really want computers to be multimodal. When you watch a science fiction show like Star Trek, someone walks up to a wall and starts touching things and speaking to a computer at the same time. That’s the way that I think our interfaces need to evolve. You need to be able to start using email, touching things on screen, speak to it, touch more things, and not really have to think about ‘am I using Voice now or not using Voice.’ You just use the computer input that is most natural at that time.”

That sounds a little more advanced than how we described the first release of Majel, but Matias said they were already working on the user interface for the next version of Android, codenamed Jelly Bean, and the next version after that.

We’re just in the early stages of comprehending how large a project Majel has become, but we still expect some kind of release on Android devices early next year. Google engineers are already testing a version of Majel that might be released as an upgrade to Google’s Voice Actions application, but we fully expect it will be a core part of Android’s next major release.

Hopefully, we will have some concrete details to share in the coming weeks.

Educational robots to introduce children to robotics, physics, programming

educational robot called Thymio II

Thymio II robot (credit: EPFL)

EPFL scientists have developed an educational robot called Thymio II, designed to introduce children to technology in school and priced inexpensively (about 99 francs, or $110 U.S.).

Thymio II has sensors and associated LEDs, and can exhibit a wide range of behaviors that can be used in teaching physics and other subjects. Sensors include proximity sensors, ground-directed sensors (it can detect the edge of a table around which it’s circulating, or a line to follow), accelerometers, microphone, and temperature sensor. It also has a memory card for recording sound.

Basic behavior modes include “friend” (follows an object in front of it), “explorer” (avoids obstacles), “coward” (detects impacts and empty space), and “investigator” (follows a line on the ground). By hooking it up to a computer via USB cable, users can invent and program other behaviors, using open-source EPFL-developed software called Aseba .

No word if iOS and Android interfaces are planned, or about its availability in the U.S. and elsewhere.

Ultrafast, nanoscale, energy-efficient data transmission

November 29, 2011 by Editor

nanoscale data transmission

nanoscale data transmission

A new ultrafast, nanoscale light-emitting diode (LED) device developed at Stanford’s School of Engineering transmits data at ultrafast rates while using 2,000 times less energy than laser-based systems in use today,” The nanophotonic device is a major step forward for on-chip data transmission, the researchers say.

The device can transmit data at 10 gigabits per second. The researchers say it is a major step forward in providing a practical ultrafast, low-power, room-temperature light source for on-chip data transmission.

The LED is a “single-mode LED,” a special type of diode that emits light more or less at a single wavelength, similar to a laser. Traditionally, engineers have thought only lasers can communicate at high data rates and ultralow power.

Nanophotonics is key to the technology. In the heart of their device, the engineers have inserted quantum dots using the light-emitting material indium arsenide, which, when pulsed with electricity, produce light. These quantum dots are surrounded by a photonic crystal — an array of tiny holes etched in a semiconductor. The photonic crystal serves as a mirror that bounces the light toward the center of the device, confining it inside the LED and forcing it to resonate at a single frequency.

Existing devices are actually two devices: a laser coupled with an external modulator. Both devices require electricity. The diode combines light transmission and modulation functions into one device, drastically reducing energy consumption.

Why Big Media Is Going Nuclear Against The DMCA
ASHKAN KARBASFROOSHAN

nuclear

nuclear disaster about to be avoided

Editor’s note: The following guest post was written by Ashkan Karbasfrooshan, founder and CEO of WatchMojo.
When Congress updated copyright laws and passed the Digital Millennium Copyright Act (DMCA) in 1998, it ushered an era of investment, innovation and job creation.  In the decade since, companies like Google, YouTube and Twitter have emerged thanks to the Act, but in the process, they have disrupted the business models and revenue streams of traditional media companies (TMCs).  Today, the TMCs are trying to fast-track a couple of bills in the House and Congress to reverse all of that.

Through their lobbyists in Washington, D.C., media companies are trying to rewrite the DMCA through two new bills.  The content industry’s lobbyists have forged ahead without any input from the technology industry, the one in the Senate is called Protect IP and the one in the House is called E-Parasites.  The E-Parasite law would kill the safe harbors of the DMCA and allow traditional media companies to attack emerging technology companies by cutting off their ability to transact and collect revenue, sort of what happened to Wikileaks, if you will.  This would scare VCs from investing in such tech firms, which in turn would destroy job creation.
The technology industry is understandably alarmed by its implications, which include automatic blacklists for any site issued a takedown notice by copyright holders that would extend to payment providers and even search engines.   What is going on and how exactly did we get here?

What is the DMCA and what are the Safe Harbors?
The Digital Millennium Copyright Act (DMCA) updated copyright laws when Congress passed it in 1998 by providing four safe harbors including legal protection from copyright-infringing “information residing on systems or networks at the direction of users.” The DMCA set up an important balance that gave online service providers freedom from liability if they pulled down content upon notification.
In doing so, the DMCA basically allowed user-generated sites to grow and prosper by sheltering them from unfair demands and excessive litigation by traditional media companies (TMCs) when a user did upload infringing content.
Why are Media Companies Unhappy with the DMCA

The DMCA put the burden of identify infringing content on the TMCs, whereby for example NBC Universal had to notify YouTube that someone had uploaded a clip of Lazy Sunday and ask them to take it down.  So long as YouTube removed the video in question then no one got hurt, though some argue that this chain of events has in fact hurt TMCs.
Why are Media Companies Going Nuclear With Pre-Emptive Strike
A cynic would argue that TMCs are essentially applying the same strategy as tech firms just through different channels.  In other words, when venture capitalists fund entrepreneurs to write code which is intended to “disrupt stodgy old industries” (to quote from Sean Parker’s LinkedIn profile), no one objects when traditional content companies are not asked for their “input.”
Obviously it’s not quite the same: the bills would affect an entire industry (if not the entire economy) for the next generation of Internet startups whereas when a VC invests in a company it is a more limited act, even if that startup has the potential to “change the world” the way Napster or YouTube did.

Furthermore, the fact that emerging companies disrupt TMCs is evolution and a manifestation of the survival of the fittest.  While some will argue that TMCs are relying on lawyers, whereas tech firms compete in the marketplace, the truth is that many tech firms buy time by hiding behind the DMCA, further frustrating the TMCs.
The other reason why TMCs are being “proactive” is that it takes a lot of resources to chase down infringers, both through takedown notices and then through subsequent litigation.  In some cases, the most brass-knuckle approach is being replaced by carrots.  But when you consider that Viacom’s lawsuit against YouTube was “too little too late”, maybe the TMCs are pursuing this kind of pre-emptive, draconian first strike strategy to make the tech firms they are targeting more willing to play ball.

Indeed, now that the TMCs are showing their willingness to go nuclear, they hope that VCs and tech firms may become more inclined to engage TMCs on their terms.
Impact of Bills on Startups, Job Creation Investor Fred Wilson is drawing attention to the two new bills, arguing that “these bills were written by the content industry without any input from the technology industry. And they are trying to fast track them through congress and into law without any negotiation with the technology industry.”  He adds, “the last negotiation produced an excellent compromise that has stood the test of time and allowed important new services like Google, Facebook, YouTube, and Twitter to be created and become large companies and massive job creators.”
He’s right.  No one doubts that these bills would spell the end of the Internet as we know it.  It’s also likely that the jobs created by tech firms over the past two decades far outweigh the jobs lost at TMCs.
But it’s fair to say that had the TMCs not gone ballistic, then perhaps the tech firms and the VCs who back them would not have cared so much about renewing the dialog and listening to the TMC’s wish list.  Case in point, Mr. Wilson extends the olive branch in his post: “If another negotiation is in order to amend the DMCA, then let’s have it.”
There’s a saying that it’s easier to ask for forgiveness than it is to ask for permission; that sums up some of the thinking of tech firms over the years.  It could now be argued that the TMCs are not asking for permission to try to rewrite the law and will hope that their pre-emptive strike will allow them to ask for forgiveness when the dust settles.
Both sides are driven by greed and fear, but if the TMCs get their wish and blow the DMCA away, then the uncertainty around the corner might come back and haunt them.  The technology industry will adapt if it needs to, and who knows what that will mean for the media industry.  After all, better the devil you know than the one you don’t.

Major banks loaning billions to companies doing mountaintop removal coal mining

Major banks loaning billions to companies doing mountaintop removal coal mining

 

Major banks loaning billions to companies doing mountaintop removal coal mining

It's getting hot up in here!

Many major banks invest in companies that engage in the environmentally destructive practice of mountaintop removal coal mining, whereby the tops of mountains are blown up to expose the recoverable coal. Despite some banks’ stated intent to limit such financing, a Sierra Club/Rainforest Action Network ‘report card’ indicates that few are yet walking the talk.

Dear EarthTalk: I understand that mountaintop removal as a way of coal mining is incredibly destructive. Didn’t a report come out recently that named major banks that were funding this activity? – Seth Jergens, New York, NY

A: Yes, it’s true that many major banks invest in companies that engage in the environmentally destructive practice of mountaintop removal (MTR) coal mining, whereby the tops of mountains are removed by explosives to expose thin seams of recoverable coal.

The wasted earth and other materials are either put back onto the mountain top in an approximation of their original contours, wreaking havoc on local ecosystems and biodiversity, or dumped into neighboring valleys, polluting lakes and streams and jeopardizing water quality for humans and wildlife.

According to the nonprofit Rainforest Action Network, this dumping — especially throughout Appalachia where MTR is most prevalent — “undermines the objectives and requirements of the Clean Water Act.”

The group adds that some 2,000 miles of streams already have been buried or contaminated in the region. “The mining destroys Appalachian communities, the health of coalfield residents and any hope for positive economic growth.”

This past April, RAN teamed up for the second year in a row with another leading nonprofit green group concerned about MTR, the Sierra Club, in publishing a “report card” reviewing 10 of the world’s largest banks in regard to their financing of MTR coal mining projects.

The new 2011 version of “Policy and Practice” takes a look at the MTR-related financing practices of Bank of America, CitiBank, Credit Suisse, Deutsche Bank, GE Capital, JPMorgan Chase, Morgan Stanley, PNC, UBS and Wells Fargo.

What did they find? Since January 2010, the 10 banks reviewed have provided upwards of $2.5 billion in loans and bonds to companies practicing MTR.

While some of the banks — Chase, Wells Fargo, PNC, UBS and Credit Suisse — adopted policies limiting their financing of MTR, few actually pulled funding in place from any such activities upon adopting such policies.

Citibank, despite announcing publicly in 2009 that it would limit its involvement in MTR, doubled its investments in the business in 2010.

RAN and the Sierra Club are also keeping a close eye on UBS, which, soon after stating that it “needs to be satisfied that the client is committed to reduce over time its exposure to (MTR),” went ahead and acted as a paid advisor on the merger of Massey Energy, which operated the West Virginia mine where 29 men died last year, and Alpha Natural Resources.

This merger created the largest single MTR company in the country, now responsible for some 25 percent of coal production from MTR mines.

The report card grades each bank based on its current position and practice regarding MTR investments, and calls on the banks to strengthen their policies and cease their financial support for coal companies engaging in MTR.

“The ‘best practice’ … is a clear exclusion policy on commercial lending and investment banking services for all coal companies who practice mountaintop removal coal extraction,” says RAN.

What is history anyway? Most people would say it’s what happened in the past, but how far back does the past extend? To the first written sources? To what other forms of evidence reveal about pre-literate civilizations? What does that term mean – an empire, a nation, a city, a village, a family, a lonely hermit somewhere? Why stop with people: shouldn’t history also comprise the environment in which they exist, and if so on what scale and how far back? And as long as we’re headed in that direction, why stop with the earth and the solar system? Why not go all the way back to the Big Bang itself?

There’s obviously no consensus on how to answer these questions, but even asking them raises another set of questions about history: who should be doing it? Traditionally trained historians, for whom archives are the only significant source? Historians willing to go beyond archives, who must therefore rely on, and to some extent themselves become, psychologists, sociologists, anthropologists, archeologists? But if they’re also going to take environments into account, don’t they also have to know something about climatology, biology, paleontology, geology, and even astronomy? And how can they do that without knowing some basic physics, chemistry, and mathematics?

You see where this is going: history, by this capacious definition, includes everything that has happened up until the present moment – and because the present moment has already become the past by the time you’ve finished reading this sentence, history must also provide a basis (what other one could there be?) for anticipating the future.

What is to prevent history, then, from being the study of “life, the universe, and everything,” as the late Douglas Adams proposed in his The Hitchhiker’s Guide to the Galaxy? Nothing in principle, but there is a problem in practice, which is that no one person, or academic department, or professional discipline, or method of inquiry, can do it all. Students of this kind of Very Big

History have for very good reasons divided themselves into fields, sub-fields, and even micro-fields, knowing that things rarely get simpler the more closely you look at them.

Much good has come of this. Our knowledge of this capaciously defined past has expanded exponentially over the past several hundred years. We now have a much clearer sense of who we are and where we came from than was available, say, to Copernicus, when he first ventured the suggestion that the universe did not revolve around us.

Some bad has come of this process as well, however. For if the volume of information in relation to time looks like a hockey stick as it approaches our era, rapidly accelerating in the production of contemporary knowledge –then it is a laminated hockey stick, the parts of which define a trajectory without interacting with one another. How much do we really know, therefore, about where we came from, who we are – and where we may be going – if the disciplines we’ve divided ourselves into have lost the languages that would allow them to speak to anyone apart from themselves?

Moreover, it seems likely that the disciplines themselves develop less than optimally when they lack ready access to each other’s insights and methods. Indeed it seems likely that history suffers most of all from such segmentation. At least to some extent history, more than the study of literature, or economics, or political science (though perhaps not much more than anthropology or sociology) aims to integrate the understanding of how human social arrangements, technologies, interactions with the larger biosphere, intellectual creations, and even our habitual cognitive and emotional responses to the world around us have changed over a given period of time: no matter what s/he emphasizes as a researcher, the person who teaches a history of 19th century England knows it cannot omit dramatic changes in birth and death rates, the expansion of suffrage, the publication of The Origin of Species, the expansion of overseas possessions, or the environmental consequences of industrialization. So despite what has sometimes seemed a strong allergy to “theory” (of various sorts) in history departments, historians may have the most to gain by opening more lines of communication to people studying change over time in various phenomena and on various time-scales.

These papers have grown out of a series of conversations and meetings, sponsored by the Santa Fe Institute, on how we might recover such languages. It proceeds from the proposition that if generalization is necessary within particular disciplines – how could it not be? – then it should also be useful across all the disciplines that take, as the subject of their inquiries, Very Big History. It pursues the possibility of taking what one of our contributors, Murray Gell-Mann, has called “a crude look at the whole.” It explores the possibility that the sciences of complexity and its many tributary fields and concepts pioneered at Santa Fe, may provide new methods, or minimally

metaphors, by which to do this. It is premised on the notion that curiosity – the foundation of all knowledge – requires the ability to be both a specialist and a generalist at the same time. And that this simultaneity of perspective is in need of new trans-disciplinary approaches and ideas.

Our title History, Big History and Metahistory, requires a brief explanation. By “history,” we mean the study, chiefly, of written records, extending from the most ancient cuneiform tablet through the most recent e- mails and twitters. By “big history,” we mean all reconstructions of the past that do not rely on written materials. By “metahistory,” we mean the patterns that emerge from both modes of inquiry that make generalization, and hence analysis, possible. We do not mean to imply by this sequence of terms that moving to the method and scale of “big history” is the only way to search for meaningful patterns. We are, however, confident that juxtaposing types of inquiry developed to deal with change in literate societies and those developed to deal with a much longer record of change has proved to be one very useful way of exposing important, often neglected questions, both about what it makes sense to look for in the always incomplete records of the past and about how to do the looking.

As in any good discussion, our contributors do not all agree with one another. Some insist that there are unifying principles, or laws, to which both human and biological history are subject. Others seek ideas, tools, and perhaps standards of truth from dynamical systems, evolution, and statistics that could augment traditional approaches to history, but do not necessarily see such borrowings as requiring that history and big history become a single discipline. One contributor sees any attempt at unification in the humanities as dangerous, and citing as precedents the extent to which social Darwinism was used to abuse less powerful people and societies. All do share the view, however, that history is too important – and too encompassing – to be analyzed exclusively through the methods of qualitative text-based narratives. We have arranged our contributors alphabetically, for no better reason than to shuffle their ideas and to avoid enforcing on this journal’s readers the editor’s conclusions.

We start with David Christian who discusses the chronometric revolution, and how this has lead to a single historical continuum stretching all the way back to the big bang, allowing for what he calls, Grand Unified Stories.

Douglas Erwin explores how paleontologists deal with the vagaries of preservation, and how statistical techniques developed in biology, have been applied to textual evidence, and the complexities of non-uniform trends leading to convergent and parallel events.

John Gaddis shows that several 19th century searches for a science of history – those of Leo Tolstoy, Carl von Clausewitz, and Henry Adams –

grasped key concepts of complexity theory, but lacked the means of visualizing and verifying it that are available today.

Murray Gell-Mann discusses the nature of empirical regularities, and their relationship to measures of complexity. Gell-Mann illustrates how apparently complex histories and patterns can sometimes be organized using simple models of growth and scaling.

Geoffrey Harpham discusses the possible limitations and abuses of unified frameworks of explanation, using the history of philology as a case study. Unchecked, scientific trajectories in a social matrix can lead to unjustified inferences.

David Krakauer introduces a range of concepts from non-linear dynamics, statistical physics and evolutionary biology, that he argues should be of use to all students of history. Using examples from traditional historicism, Krakauer shows how history often uses analogs of concepts and tools expressed quantitatively in the natural sciences.

John McNeill explores parallels between cultural and biological evolution, exploring patterns of increasing cultural heterogeneity through time, and the role that specialist (pandas) and generalist (pigs) societies and states have played in explaining these patterns.

Ken Pomeranz describes the ways in which naming historical phenomena influences how we then analyze them. Arguing that many of the classification schemes that are conventional among historians serve some other purposes well, but are not very conducive to seeking meaningful generalizations or engaging in dialogue with scientists, he suggests other approaches, while also giving reasons why they are far more likely to complement than displace currently popular taxonomies.

Fred Spier, speaking as an historian, explores how big history might be brought within a reductive framework of physics, using the concept of free energy rate density, as a means of organizing major transitions, from the abiotic to the biotic and cultural domains.

Peter Turchin explores the value of general quantitative theory in areas where prediction is limited, and comparative data and retrodiction need to be explored. The transformation of natural history into quantitative biology is used as possible precedent and model for a transformation of qualitative history.

Geerat Vermeij considers a grand, economic theory of history, in which biology and culture might both be subsumed. Concepts of competition, feedback and power provide potential unifying historical concepts.

Geoffrey West argues for quantitative approaches to history through a suitable choice of coarse-grained variables. West argues that is unlikely that we shall discern common patterns at the level of individuals, but if we allow

ourselves to study collective phenomena, such as urban systems, then we might make surprising new discoveries.

No reader is likely to find all of these contributions persuasive, or perhaps even congenial. Nonetheless, we think that most will gain more from engaging with them in their current diversity than they would gain from any superficial consensus we could wring from them. Readers may think of some papers as introducing them to new tools, potentially useful for their current inquiries or for others they had previously deemed impossible. Others stand as arguments about what sorts of inquiries should be attempted; still others as preliminary reports from lines of inquiry (in various historical disciplines) that it would be good for a wider range of scholars to know about. Each of these, of course, bears on the others, at least indirectly: what we should ask, what tools we have for answering new and old questions, and what people have found by asking unusual questions or using unusual tools are obviously overlapping issues. The overlaps on display here are not nearly large enough to let us suggest a single, unified agenda for further work; they are, however, sufficiently numerous to suggest many places where more focused inter-disciplinary projects might take root and prove fruitful. Perhaps even more important, these efforts should give readers what the meetings they sprang from gave to its participants: a better sense of the range of conversations we might join, the opportunities and problems in those discussions, and some ways in which joining new conversations will give us new ways of analyzing our common past.

How Many Neutrinos Does It Take to Screw Up Einstein?

Major banks loaning billions to companies doing mountaintop removal coal mining

Einstein

Click here to find {out}

 

Results from a second experiment uphold the observation that neutrinos are moving faster than the speed of light. The OPERA collaboration, which first reported the superluminal neutrinos in September, has rerun the experiment and detected 20 new neutrinos breaking Einstein’s theoretical limit.

 

The findings are heartening to anyone hoping to see a major physics revolution in their lifetime. But scientists, as ever, are being cautious, and it will take an independent replication of the results by another team to even begin convincing many of them.

 

“This eliminates one major class of systematic errors, and it’s impressive for the OPERA team to have mounted in a short period of time,” said physicist Robert Plunkett of Fermilab National Laboratory in Batavia, Illinois. “However, it doesn’t mean that there isn’t an error somewhere else in their system.”

 

Neutrinos are subatomic particles with hardly any mass that are able to fly through most matter as if it weren’t there. Despite their negligible mass, if they were somehow able to exceed the speed-of-light limit set by Einstein’s theory of special relativity, it would present a major head-scratcher to modern physicists.

 

 

 

The OPERA team’s detector at Gran Sasso National Laboratory in Italy had previously detected neutrinos produced in bunches at CERN arriving 60 nanoseconds earlier than light speed would allow. The tricky part is that these bunches took a good length of time to produce — much longer than 60 nanoseconds — so the researchers had to be careful with their analysis. If they thought a neutrino was coming from the start of the bunch when it was actually coming from the end, then that neutrino would not actually be moving faster than light.

 

In their first experiment, the OPERA team used statistical analysis to show this situation was unlikely, but other scientists were not completely persuaded. The new experiment produced neutrinos in bunches over just three nanoseconds, far shorter than the faster-than-light anomaly. The results were the same: Neutrinos arrived 60 nanoseconds quicker than the speed of light. The findings were robust enough that members of the OPERA collaboration who had refused to sign on to the first paper were now willing to put their name on the new one.

 

But a great deal of scrutiny remains.

 

“I can now say that the probability of the result being correct has increased from 1 in a million to one in 100 thousand,” wrote physicist Philip Gibbs on the viXra log (though he stressed that those numbers were merely illustrative and not actual calculated values).

 

Tommaso Dorigo, a physicist at CERN, noted on his blog that there are still other possible sources of error. For instance, the OPERA collaboration’s clock might not have a fine enough resolution to determine exactly when the neutrinos arrived. “The measurement therefore is only a ‘partial’ confirmation of the earlier result: It is consistent with it, but could be just as wrong as the other,” he wrote.

 

Ultimately, the only thing that would convince many in the field is if another team upholds the findings in an independent experiment. Plunkett, co-spokesperson for the Main Injector Neutrino Oscillation Search(MINOS) experiment at Fermilab, says that his collaboration expects to have results checking the OPERA findings in the spring of 2012.

Alignment of the Earth and Milky Way on December 21st 2012?

nuclear

nuclear disaster about to be ??

Look we all the the internet hype about what will occur. About the Mayan Calender lets be logical, could it be they ran out of space and became and obselete race before they could have created a new calender? Also if the new Calendar started some five thousand years ago it must be documented what happened at the “end” of the last long count calendar. What worries me is there is no scientific data what occurred 26,000 years ago when there was the last alignment of the earth and the milky way. When that happens ,what happesn to the earth?What happens to the human race, did the last set of people survive? Ill like to hear from actual scientist. Your use of the word ‘alignment’ is incorrect. Due to precession, the Earth’s axial tilt will reach it’s maximum of 60 degrees in relation to the equatorial plane of the Milky Way galaxy.

Regarding internet hype, my best advice is to avoid the internet when researching 2012. The subject has attracted doomsayers, end-of-the-world armegeddonists, occultists, and just plain misinformed kooks. Many of these websites exist not to give credible and real information but to make money as most websites do by attracting sponsors. There exists only one credible author who has devoted the last decade into researching the Mayan culture and calendars. John Major Jenkins. If you are interested in learning the facts regarding 2012, this is your starting point.

The long-count calendar was one based upon the 26,000 year precession of Earth’s axial wobble. Contrary to another answer on this page, the Mayans were some of the greatest astronomers and mathematicians to have lived. They divided the 26,000 year precessional cycle into 5 Ages of about 5,125 years each. This is the age which comes to an end 2012. This is not the end of their calendar any more than our calendar ends in 2007. In 2013, the next Age begins and will last 5,125 years in the same way that our Gregorian calendar will go to 2008. The Mayan calendar is further subdivided into tuns, baktuns, etc the same as we divide ours into months and weeks.

I have yet to find out why the Mayan divided the procession into 5 instead of what would seem to be a more logical 4. Their only “prediction” is that each of these ages ends in a certain way. The age we are now in is called the age of the jaguar. When the jaguar dies, it’s body will shiver and quake. This would be a referrence to the Earth experiencing earthquakes and possibly volcanic activity. This is the only Mayan prediction. All others are false and have been made up during the last ten years by people living today to assert fear and confusion. Mayans have never spoke of any age as the ‘end of the world’ as unfortunately most people assume. They only spoke of the ending of an age as a time of transition. This is what is the cause of so much of the confusion and scare-hype happening on the internet these days. 2012 has absolutely nothing to do with asteroids or polarity flips.

The Mayan were aware of naturally occuring cycles. The age that ended 3114BC was the age of water. Documented evidence does not exist but one could suppose that that may have been the time of the Biblical flood which is also spoken of in many other cultures of the globe. We know that previous civilizations have existed in the far past yet we have very little in the form of historical documents that go much beyond the last 2000 years. Information does not even exist about the building of the Egyptian pyramids or the Sphinx. One could presume that the demise of these previous civilizations were possibly caused by global catastrophies.

Clearly, the last set of humans did survive otherwise you and I would not be here today. Exactly what happened at the ends of the other ages will probably never be known. Nor the percentage of humans that died or survived. Possibly 26,000 years from now the records of today may still exist. But who can say?

I am not a scientist. I am just trying to give people proper education regarding a subject which unfortunately has become so twisted and mangled with misinformation and lies. This is an astronomical event which occurs only once every 26,000 years. Look forward to it with admiration and respect, not fear.

Prey humans!

Quantum theorem shakes foundations

Major banks loaning billions to companies doing mountaintop removal coal mining

Einstein

 

 

 

 

Source: Nature News

The wavefunction of quantum mechanics is not simply a statistical tool that reflects our ignorance of the particles being measured, but is physically real, according to physicists at Imperial College London.

Action at a distance occurs when pairs of quantum particles become entangled. The paper suggests that if a quantum wavefunction were purely a statistical tool, even quantum states that are unconnected across space and time would be able to communicate with each other. As that seems very unlikely, the researchers conclude that the wavefunction must be physically real after all.

Theoretical physicist Antony Valentini believes that this result may be the most important general theorem relating to the foundations of quantum mechanics since Bell’s theorem.

Robert Spekkens, a physicist at the Perimeter Institute for Theoretical Physics, says he expects the theorem to have broader consequences for physics, as have Bell’s and other fundamental theorems. No one foresaw in 1964 that Bell’s theorem would sow the seeds for quantum information theory and quantum cryptography — both of which rely on phenomena that aren’t possible in classical physics.

‘Giant’ piezoelectric material integrated with silicon for ‘hyperactive’ MEMS

Major banks loaning billions to companies doing mountaintop removal coal mining

Einstein

 

 

 

 

University of Wisconsin-Madison engineers and physicists have integrated a complex, single-crystal material with “giant” piezoelectric properties onto silicon. It can be used to fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.

Piezoelectric materials use mechanical motion to generate an electrical signal, such as the light that flashes in some children’s shoe heels when they stomp their feet. Conversely, piezoelectrics also can use an electrical signal to generate mechanical motion; for example, piezoelectric materials are used to generate high-frequency acoustic waves for ultrasound imaging.

Led by Chang-Beom Eom, a UW-Madison professor of materials science and engineering and physics, the researchers study the advanced piezoelectric material lead magnesium niobate-lead titanate, or PMN-PT. Such materials exhibit a “giant” piezoelectric response that can deliver much greater mechanical displacement with the same amount of electric field as traditional piezoelectric materials. They also can act as both actuators and sensors. For example, they use electricity to deliver an ultrasound wave that penetrates deeply into the body and returns data capable of displaying a high-quality 3-D image.

Currently, a major limitation of these advanced materials is that to incorporate them into very small-scale devices, researchers start with a bulk material and grind, cut, and polish it to the size they desire. It’s an imprecise, error-prone process that’s intrinsically ill-suited for nanoelectromechanical systems (NEMS) or microelectromechanical systems (MEMS).

Until now, the complexity of PMN-PT has thwarted researchers’ efforts to develop simple, reproducible microscale fabrication techniques. Applying microscale fabrication techniques such as those used in computer electronics, Eom’s team has overcome that barrier, integrating PMN-PT seamlessly onto silicon. Because of potential chemical reactions among the components, they layered materials and carefully planned the locations of individual atoms.

Hyperactive MEMS

Onto a silicon “platform,” they add a very thin layer of strontium titanate, which acts as a template and mimics the structure of silicon. Next comes a layer of strontium ruthenate, an electrode Eom developed some years ago, and finally, the single-crystal piezoelectric material PMN-PT.

His team calls devices fabricated from this giant piezoelectric material “hyperactive MEMS” for their potential to offer researchers a high level of active control. Using the material, his team also developed a process for fabricating piezoelectric MEMS.

Applied in signal processing, communications, medical imaging and nanopositioning actuators, hyperactive MEMS devices could reduce power consumption and increase actuator speed and sensor sensitivity. Additionally, through a process called energy harvesting, hyperactive MEMS devices could convert energy from sources such as mechanical vibrations into electricity that powers other small devices; for example, for wireless communication.

“Search for alien life should include exotic possibilities I say” Al

exoplanet

A U.S./German research team proposes to rank planets on both an Earth Similarity Index (ESI) and also a broader Planetary Habitability Index (PHI), Wired Science reports.

The first index looks at how close a planet is to Earth in mass, temperature, and composition while the second is based on the whether or not it possesses more exotic chemistries, liquids, and energy sources than found on our planet. For example, Titan gets a rather low ESI but a more optimistic, middle-range PHI.

Alien life could be based on elements other than carbon, require liquids other than water, and gain energy through means other than sunlight.

ATLUM Project: A Connectome Observatory for nanoscale brain imaging

Dr. Ken Hayworth, a postdoctoral fellow at Harvard University and designer of the Automatic Tape-Collecting Lathe Ultramicrotome (ATLUM), proposed to build a “Connectome Observatory” for nanoscale brain imaging in an online talk Sunday, How to create a Connectome Observatory of the mouse brain and beyond, presented in teleXLR8, a 3D interactive video conferencing space.

Hayworth suggested that Focused Ion Beam Scanning Electron Microscopes (FIBSEM) now permit imaging brain tissue at resolutions approaching 5x5x5nm. voxel size, down to the protein level. “This is more than sufficient resolution to determine all the connectivity and the properties of the synapses that are needed to explain the functionality of the brain circuits,” he said.

Hayworth presented a technique that can section large blocks of plastic-embedded brain tissue into 20 micron thick strips, optimally sized for high-resolution 5 nm. FIBSEM imaging. This thick sectioning procedure results in such high-quality surfaces that the finest neuronal processes can be traced from strip to strip, permitting a lossless subdivision of brain tissue in blocks that can be imaged by many FIBSEMs working in parallel, he said.

A ‘cure for death’

The Connectome Observatory would be a resource to be shared by the entire neuroscience community, on which individual researchers can schedule imaging time for their projects exploring brain circuits at their finest level. Initially, it would be dedicated to mouse brain imaging for research purposes, but more ambitious applications can be envisaged.

“In 100 years, if we have the technology to bring someone back, it won’t be in a biological body,” Hayworth said in a New York Times article last year. “It is these scanning techniques and mind-uploading that, I think, will bring people back. This is a taboo topic in the scientific community. But we have a cure to death right here. Why aren’t we pursuing it?”

He said many neuroscientists believe that unique individual memory is stored exclusively or primarily in the large-scale synaptic and dendritic structure of the connectome, whose preservation can be the “cure to death,” as noted in “Killed by Bad Philosophy: Why brain preservation followed by mind uploading is a cure for death.”

Hayworth is also a co-founder of the Brain Preservation Foundation (BPF), focused on the exploration of brain preservation technology. The BPF offers a Brain Preservation Technology Prize that will go to the first team to successfully preserve a whole large animal brain in a manner that could also be adopted for humans in a hospital or hospice setting immediately upon clinical death. In the Q&A, participants compared connectome preservation via the chemical brain preservation techniques proposed by the BPF to cryonics.

“If there was really a concerted effort to develop brain preservation technology, it would be easy to have highly reliable hospital brain preservation procedures ready to go in any hospital before the end of the decade. It is all a matter of will.” More

Stem cells join muscle, spinal cord cells in ‘human-on-a-chip’ simulation

 

God

God

University of Central Florida researchers, for the first time, have used stem cells to grow neuromuscular junctions between human muscle cells and human spinal cord cells, the key connectors used by the brain to communicate and control muscles in the body.

.The National Institutes of Health (NIH), the Defense Advanced Research Projects Agency (DARPA), and the Federal Drug Administration (FDA) have recently launched an ambitious plan to jump-start research in “human-on-a-chip” models by making available at least $140 million in grant funding.

The goal is to produce systems that include various miniature organs connected in realistic ways to simulate human body function. This would make it possible, for instance, to test drugs on human cells well before they could safely and ethically be tested on living humans. The technique could potentially be more effective than testing in mice and other animals currently used to screen promising drug candidates and to develop other medical treatments.

Such nerve-muscle junctions might prove to be important research tools. These junctions play key roles in Amyotrophic lateral sclerosis, commonly known as Lou Gehrig’s disease, in spinal cord injury, and in other debilitating or life threatening conditions. With further development, the team’s techniques could be used to test new drugs or other treatments for these conditions even before more expansive chip-based models are developed.

Displair, a Russian company from Astrakhan, has come up with a technology to project images into the thin air, and use gestures to move them.

The company uses a stream of cold fog to project images onto it and an infrared camera to capture gestures. Unlike oversized body movements that Microsoft Kinect analyze and process using motion camera and infrared depth sensors, Displair solves a bigger challenge of detecting and interpreting finer movements of hands.

When manufactured in large quantities, the device may cost between $4,000 and $30,000.

Rebuilding the brain’s circuitry using embryonic neurons

Transplanted Hypothalamic Cells

Transplanted Hypothalamic Cells

 

Harvard researchers and colleagues have repaired brain circuitry and substantially normalized function in mice with a brain disorder using neuron transplants, an advance indicating that key areas of the mammalian brain are more reparable than was widely believed.

Collaborators from Harvard University, Massachusetts General Hospital (MGH), Beth Israel Deaconess Medical Center (BIDMC), and Harvard Medical School (HMS) transplanted normally functioning embryonic mouse neurons at a carefully selected stage of their development into the hypothalamus of mice unable to respond to leptin (a hormone that regulates metabolism and controls body weight).

These mutant mice usually become morbidly obese, but the neuron transplants repaired defective brain circuits, enabling them to respond to leptin and thus experience substantially less weight gain.

Repair at the cellular-level of the hypothalamus — a critical and complex region of the brain that regulates phenomena such as hunger, metabolism, body temperature, and basic behaviors such as sex and aggression — indicates the possibility of new therapeutic approaches to even higher-level conditions, such as spinal cord injury, autism, epilepsy, ALS (Lou Gehrig’s disease), Parkinson’s disease, and Huntington’s disease.

“There are only two areas of the brain that are known to normally undergo ongoing large-scale neuronal replacement (neurogenesis) during adulthood on a cellular level: in the olfactory bulb and the subregion of the hippocampus called the dentate gyrus … and in the hypothalamus,” said Jeffrey Macklis, Harvard University professor of stem cell and regenerative biology and HMS professor of neurology at MGH, and one of three corresponding authors on the paper.

“The neurons that are added during adulthood in both regions are generally smallish and are thought to act a bit like volume controls over specific signaling. Here we’ve rewired a high-level system of brain circuitry that does not naturally experience neurogenesis, and this restored substantially normal function.”

The two other senior authors on the paper are Jeffrey Flier, dean of Harvard Medical School, and Matthew Anderson, HMS professor of pathology at BIDMC.

In 2005, Flier, then the George C. Reisman professor of medicine at BIDMC, published a landmark study showing that an experimental drug spurred the addition of new neurons in the hypothalamus and offered a potential treatment for obesity. But while the finding was striking, the researchers were unsure whether the new cells functioned like natural neurons.

Macklis’ laboratory had for several years developed approaches to successfully transplanting developing neurons into circuitry of the cerebral cortex of mice with neurodegeneration or neuronal injury. In a landmark 2000 Nature study, the researchers demonstrated induction of neurogenesis in the cerebral cortex of adult mice, where it does not normally occur. While these and follow-up experiments appeared to rebuild brain circuitry anatomically, the new neurons’ level of function remained uncertain.

To learn more, Flier, an expert in the biology of obesity, teamed up with Macklis, an expert in central nervous system development and repair, and Anderson, an expert in neuronal circuitries and mouse neurological disease models.

The groups used a mouse model in which the brain lacks the ability to respond to leptin. Flier and his lab have long studied this hormone, which is mediated by the hypothalamus. Deaf to leptin’s signaling, these mice become dangerously overweight.

Prior research had suggested that four main classes of neurons enabled the brain to process leptin signaling. Postdocs Artur Czupryn and Maggie Chen, from Macklis’ and Flier’s labs, respectively, transplanted and studied the cellular development and integration of progenitor cells and very immature neurons from normal embryos into the hypothalamus of the mutant mice using multiple types of cellular and molecular analysis. To place the transplanted cells in exactly the correct and microscopic region of the recipient hypothalamus, they used a technique called high-resolution ultrasound microscopy, creating what Macklis called a “chimeric hypothalamus” — like the animals with mixed features from Greek mythology.
Postdoc Yu-Dong Zhou, from Anderson’s lab, performed in-depth electrophysiological analysis of the transplanted neurons and their function in the recipient circuitry, taking advantage of the neurons’ glowing green from a fluorescent jellyfish protein carried as a marker.

These nascent neurons survived the transplantation process and developed structurally, molecularly, and electrophysiologically into the four cardinal types of neurons central to leptin signaling. The new neurons integrated functionally into the circuitry, responding to leptin, insulin, and glucose. Treated mice matured and weighed approximately 30 percent less than their untreated siblings or siblings treated in multiple alternate ways.

The researchers then investigated the precise extent to which these new neurons had become wired into the brain’s circuitry using molecular assays, electron microscopy for visualizing the finest details of circuits, and patch-clamp electrophysiology, a technique in which researchers use small electrodes to investigate the characteristics of individual neurons and pairs of neurons in fine detail. Because the new cells were labeled with fluorescent tags, postdocs Czupryn, Zhou, and Chen could easily locate them.

The Zhou and Anderson team found that the newly developed neurons communicated to recipient neurons through normal synaptic contacts, and that the brain, in turn, signaled back. Responding to leptin, insulin and glucose, these neurons had effectively joined the brain’s network and rewired the damaged circuitry.

“It’s interesting to note that these embryonic neurons were wired in with less precision than one might think,” Flier said. “But that didn’t seem to matter. In a sense, these neurons are like antennas that were immediately able to pick up the leptin signal. From an energy-balance perspective, I’m struck that a relatively small number of genetically normal neurons can so efficiently repair the circuitry.”
“The finding that these embryonic cells are so efficient at integrating with the native neuronal circuitry makes us quite excited about the possibility of applying similar techniques to other neurological and psychiatric diseases of particular interest to our laboratory,” said Anderson.

The researchers call their findings a proof of concept for the broader idea that new neurons can integrate specifically to modify complex circuits that are defective in a mammalian brain.

The researchers are interested in further investigating controlled neurogenesis — directing growth of new neurons in the brain from within — the subject of much of Macklis’ research as well as Flier’s 2005 paper, and a potential route to new therapies.

“The next step for us is to ask parallel questions of other parts of the brain and spinal cord, those involved in ALS and with spinal cord injuries,” Macklis said. “In these cases, can we rebuild circuitry in the mammalian brain? I suspect that we can.”

New hope for repairing diseased or damaged brains

Major banks loaning billions to companies doing mountaintop removal coal mining

November 25, 2011 by Amara D. Angelica

Two exciting landmark studies of ways to repair damaged or diseased brains have just been published, and are discussed on KurzweilAI today.

The University of Wisconsin-Madison study found that when neurons generated from human embryonic stem cells (hESC) were mplanted into the hippocampus of a mouse, the neurons began to behave like normal rat neurons. That means that for humans in the future, there could be limitless supplies of healthy, specialized cells to replace diseased or damaged cells for brain disorders such as Parkinson’s disease.

The Harvard-Massachusetts General-Beth Israel study addressed the same problem, but injected embryonic mouse (instead of human) neurons into the hypothalamus of mice unable to respond to leptin (a hormone that regulates metabolism and controls body weight). They found that the neuron transplants were able to repair defective hypothalamus brain circuits, enabling the mice to respond normally to leptin and thus experience substantially less weight gain.

These studies only address two (albeit important) brain areas, but the researchers are optimistic that these studies will lead to the ability to repair and grow diseased or damaged brain cells in higher-level conditions, such as spinal cord injury, autism, epilepsy, ALS (Lou Gehrig’s disease), Parkinson’s disease, and Huntington’s disease.

Meanwhile, progress in another vital approach to repair damaged nerves — medical micropower network systems (which transmit movement commands from a sensor on a patient’s spinal cord via special processors to implants that electrically stimulate nerves) is hitting a possible roadblock: the FCC may deny access to four sets of frequencies between 413MHz and 457MHz (also used for TV and radio signals) due to concern that the broadcast signals might interfere with the body networks.

For the millions of people in the U.S. (and possibly to the hundreds of millions in some other countries) affected by neurological disorders, the move to live TV streaming via Google TV, Apple TV, Amazon Instant Video, and other digital alternatives to broadcasting can’t come soon enough.

Lab-grown implanted neurons fuse with brain circuitry

God

Neurons generated in the lab from blank-slate human embryonic stem cells (hESC) and implanted into the brains of mice can successfully fuse with the brain’s wiring and both send and receive signals, scientists st University of Wisconsin-Madison have found — a crucial step toward deploying customized cells to repair damaged or diseased brains.

“The big question was, can these cells integrate in a functional way?” says Jason P. Weick, the lead author of the new study and a staff scientist at the University of Wisconsin-Madison’s Waisman Center. “We show for the first time that these transplanted cells can both listen and talk to surrounding neurons of the adult brain.”

The Wisconsin team tested this by transplanting the human-derived neurons into the adult mouse hippocampus, an area of the brain that plays a key role in processing memory and spatial navigation. The capacity of the human cells to integrate into the mouse brain was observed in live tissue taken from the animals that received the cell transplants.

Weick and colleagues also reported that the human neurons adopted the rhythmic firing behavior of many brain cells talking to one another in unison. And, perhaps more importantly, that the human cells could modify the way the neural network behaved.

Specifically, the study demonstrated that hESC-derived neurons adopt the bursting behavior of a preexisting neural network, can modulate the mouse network activity via synaptic output, and can elicit spontaneous postsynaptic currents in hippocampal pyramidal neurons in slices taken from transplanted mouse brains. It also demonstrated that human neurons can make both excitatory and inhibitory synaptic connections with individual mouse neurons.

Optogenetics allows for precise, noninvasive stimulation

A critical tool that allowed the UW group to answer this question was optogenetics, where light instead of electric current is used to noninvasively stimulate only the transplanted human cells.

Weick explains that the capacity to modulate the implanted cells was a necessary step in determining the function of implanted cells, because previous technologies were too imprecise and unreliable to accurately determine what transplanted neurons were doing.

The appeal of human embryonic stem cells and induced pluripotent cells is the potential to manufacture limitless supplies of healthy, specialized cells to replace diseased or damaged cells. Brain disorders such as Parkinson’s disease and amyotrophic lateral sclerosis, more widely known as Lou Gehrig’s disease, are conditions that scientists think may be alleviated by using healthy lab grown cells to replace faulty ones. Multiple studies over the past decade have shown that both embryonic stem cells and induced cells can alleviate deficits of these disorders in animal models.

The new study opens the door to the potential for clinicians to deploy light-based stimulation technology to manipulate transplanted tissue and cells. “The marriage between stem cells and optogenetics has the potential to assist in the treatment of a number of debilitating neurodegenerative disorders,” notes Su-Chun Zhang, a UW-Madison professor of neuroscience. “You can imagine that if the transplanted cells don’t behave as they should, you could use this system to modulate them using light.”

Under Pressure, Pentagon Adopts New IT Strategy

nuclear disaster about to be avoided

The CIO of the Department of Defense has devised an ambitious IT plan that aims to help the military branches cope with billions of dollars in budget cuts.

The Department of Defense is staring at a classic enterprise IT challenge, only on a massive scale. Facing billions of dollars in budget cuts, the DOD must decide where to invest its IT dollars in order to save money across its operations, and where to pinch IT spending. But with national security on the line, the stakes are much higher–it must do so without compromising its IT infrastructure and applications.

The answer comes in the form of a new plan that aims to replace the military’s branch-specific systems and networks with a more efficient, and ultimately more capable, enterprise model. The strategy will require changes that go well beyond new IT systems. “This plan commits us to changing policies, cultural norms, and organizational processes to provide lasting results,” DOD CIO Teri Takai told Congress earlier this year.

The Pentagon has the biggest IT budget of any organization in the world: $38.4 billion in fiscal 2012. But that budget’s a moving target, as the DOD is under intense pressure to cut its overall spending by tens, potentially hundreds, of billions of dollars over the next five years.

The new IT Enterprise Strategy and Roadmap identifies 26 tech initiatives to be carried out over the next 10 years. The strategy, crafted by Takai along with CIOs of the military branches, was signed by the deputy secretary of defense in early October and is due for public release this month.

The DOD drew on best practices from the private sector in devising its plan, which is spelled out in a 48-page document. The strategy identifies networking services, computing services, end user services, application and data services, and business processes as areas of focus. It provides benchmarks for sought-after efficiencies, including a 30% reduction in servers and up to $3.5 billion in savings over five years. Supplementing the IT Enterprise Strategy is an “initial implementation plan” that identifies work to be done in fiscal years 2012 and 2013, with a focus on near-term gains.

Takai, in an interview with InformationWeek, says the objectives of the IT Enterprise Strategy go beyond efficiencies that translate into cost savings. The department also wants to improve cybersecurity and broaden information sharing across the Army, Air Force, Navy, and Marines.

Some of the projects are in their early stages, but most have yet to begin. “There’s some pretty aggressive items in there,” Takai says. But she adds: “I wouldn’t call them quick wins.”

Pending Reorg

As Takai has learned in her first year on the job, quick wins are hard to come by in the vast bureaucracy of the Pentagon, which at 6.5 million square feet is more than twice the size of the Empire State Building. Her IT strategy document, originally due at midyear, is arriving months later than planned. “I’m continually surprised at the steps that need to take place here,” she says.

A former CIO of California, Takai was appointed DOD CIO in October 2010, and she immediately walked into a restructuring of the CIO’s office (which formerly had the buttoned-up moniker of Office of the Assistant Secretary of Defense for Networks and Information Integration) and the breakup of the Joint Forces Command (which had coordinated much of the IT work that cut across miliary branches).

A year later, the plan for reorganizing the CIO office has been nearly finalized but still awaits another bureaucratic step: approval by Deputy Secretary of Defense Ashton Carter. It defines more clearly the authority of the CIO to include oversight of IT spending and implementation, as well as the CIO’s relationship with three critical units: U.S. Cyber Command, which is responsible for protecting DOD networks; the Defense Information Systems Agency, or DISA, which provides IT services to the military branches; and the Office of Acquisition, Technology, and Logistics. Takai’s organization will be renamed the Office of the DOD Chief Information Officer.

The CIO office reorg is part of a broad restructuring ordered last year by Robert Gates, the secretary of defense at the time, whose goal was to lower costs by eliminating redundant functions. Takai’s appointment was a surprise to nearly everyone. She had neither of the qualifications one would expect for the job: a military background or experience in the federal government’s senior executive service.

But Takai did have three years under her belt managing California’s not-insignificant IT operations ($4 billion budget and 10,000 people), where she is credited with driving efficiency and accountability. Before that, she was CIO of Michigan and had worked in the private sector for Ford, EDS, and auto parts supplier Federal-Mogul.

Takai has two senior advisers to show her the ropes–Chief of Staff Rear Admiral Janice Hamby and Principal Deputy CIO Robert Carey, who together have years of experience in what some call simply “the building.” In our interview, Takai says the size, structure, and culture of the DOD have taken some getting used to. “It’s been important to learn the way the Office of the Secretary of Defense works vis-a-vis the military and how the entire structure is laid out,” she says.

~Bots gone wild~

Introducing random — a new, occasional blog thingie for stuff that’s way too weird for our regular weird posts. Like these wacky robot stories:

Wanna take a ride on a 15-foot-long inflatable walking robot named Ant-Roach (as in anteater-cockroach)? Um, maybe not, but hey, “human safe” bots are not a bad idea, especially if you plan to have one in your home, with kids. A future Disney attraction?

Robot prison guard prototype (credit: Yonhap)

OK, then, how about about “humane and friendly” robot prison guards that can identify “abnormal behavior”? A jail in South Korea plans to run a month-long trial with three of them, a $863,000 project. (How long will it take hacker inmates to convert them into Terminator bots?)

And then there’s OCCU(PI) Bot, carrying a sign that reads “if(justice) == 0 } occup(pi) = 1;” (get it?)  — “the first in a promising line of tireless, unstoppable, robotic class warriors,” complete with a megaphone and optional Arduino — so you could, let’s say, control it via  the Internet (“remote occupying”?).

Hmm, I wonder if it’s pepper-spray-resistant?

Meanwhile, the 1% will be happy to know that restaurants around the world will soon use new “DNA barcoding” technology to assure finicky patrons they are being served the genuine fish fillet they ordered, rather than inferior substitutes, AP reports. The biennial International Barcode of Life Conference is being held Monday to discuss compilation of a global reference library for the Earth’s 1.8 million known species; the Barcode of Life Database so far includes more than 167,000 species. (Could prevent illness too.)

Speaking of anarchy,  in case you believe the end of the world is nigh, The Guardian has compiled a doomsday list of “Strange ways to go” and their signs, such as: “If the Earth exists in a region of space known as a false vacuum, it could collapse into a lower-energy state at any point….

Sign: it could happen half way through this…”

And New Scientist has its own list of cracks in reality, including the recent finding that mesons decay differently from their antimatter counterparts (that’s why we have more matter than antimatter), which would call into question the standard model of particle physics; and a now-accepted belief in the existence of multiple universes — maybe 10500of them, or maybe an infinite number. The answer could be hiding in the cosmic microwave background, currently being mapped at higher precision by the European Space Agency’s Planck satellite.

We now return you to our normal weird news.
