Yale study links to exposure to electrical fields to brain activity [via Yale University]:

The finding helps explain why techniques that influence electrical fields such as transcranial magnetic stimulation and deep brain stimulation are effective for the treatment of various neurological disorders, including depression. The study also “raises many questions about the possible effects of electrical fields, such as power lines and cell phones, in which we immerse ourselves,” said David McCormick, the Dorys McConnell Duberg Professor of Neurobiology at Yale School of Medicine, a researcher of the Kavli Institute of Neuroscience and senior author of the study.

New study suggests that older adults benefit from “brain training” [via University of California, San Francisco]:

A commercial brain fitness program has been shown to improve memory in older adults, at least in the period soon after training. The findings are the first to show that practicing simple visual tasks can improve the accuracy of short-term, or “working” visual memory. The research, led by scientists at UCSF, is also one of the first to measure both mental performance and changes in neural activity caused by a cognitive training program.

Texas researchers grow new brain cells with experimental Alzheimer’s drug [via Reuters and YahooNews]:

The researchers’ work, done on rodents, builds on findings that all mammals, including humans, make brain cells throughout their lives. Most of these die, but this drug helps more of the baby cells survive and grow to become functioning brain cells.

“We make new neurons every day in our brain,” Andrew Pieper of the University of Texas Southwestern Medical Center in Dallas who worked on the study, said in a telephone interview. “What our compound does in allow more of them to survive.”

The compound is called P7C3 for now, and the researchers have already started tweaking it to make it more effective. They said it seems safe and appears to work even when taken as a pill.

The adult brain, long considered to be fixed in its wiring, is in fact remarkably dynamic. Neuroscientists once thought that the brain’s wiring was fixed early in life, during a critical period beyond which changes were impossible. Recent discoveries have challenged that view, and now, research by scientists at Rockefeller University suggests that circuits in the adult brain are continually modified by experience.

Scientists explore how magnetism may be responsible for ball lightening and hallucinations in humans:

Transcranial magnetic stimulation (TMS) is an extraordinary technique pioneered by neuroscientists to explore the workings of the brain. The idea is to place a human in a rapidly changing magnetic field that is powerful enough to induce currents in neurons in the brain… All that much is repeatable in the lab using giant superconducting magnets capable of creating fields of as much as 0.5 Tesla inside the brain.

But if this happens in the lab, then why not in the real world too, say Joseph Peer and Alexander Kendl at the University of Innsbruck in Austria. They calculate that the rapidly changing fields associated with repeated lightning strikes are powerful enough to cause a similar phenomenon in humans within 200 metres [via Technology Review].

Google to Introduce TV Software

Google Inc. is planning to introduce Android-based television software to developers at an event in May, according to people familiar with the matter.

The technology—designed to open set-top boxes, TVs and other devices to more content from the Internet—is attracting interest from partners that include Sony Corp., Intel Corp. and Logitech International SA, which are expected to offer products that support the software, these people said. None have so far discussed the efforts publicly. [via Wall Street Journal]

1 in 8 Consumers Will Ax Their Coax This Year

Boston, MA Apr 27, 2010 - The first cord-cutters were those who cut their traditional phone cords in favor of mobile phone services. Now Yankee Group uncovers a new category: the coax-cutter. These consumers cut off their pay TV services and use their PCs, gaming consoles and other connected devices to access video programming instead. One in 8 consumers are set to join their ranks in the next 12 months. [via Yankee Group]

Audiences, and Hollywood, Flock to Smartphones

Measured against TV ratings and box-office receipts, the mobile video audience is tiny today, but a range of companies, from Hollywood studios to local TV stations, all foresee an increasingly wireless world — and they don’t want to be cut out of the picture.

Some TV shows, like “The Office” on NBC.com, are streamed at no charge now, but there is a gnawing fear among media companies that they may be leaving money on the table by relying solely on revenue from advertising. [via New York Times]

A couple notworthy posts from Wired’s Danger Room:

Military Wants to Super-Charge Troop Smarts

The Pentagon’s been trying to get ahead of the curve on neuroscience for years, toying with ideas like mind-reading whether people are lying and performance-degrading drugs for enemy combatants. Now, it’s launching a major effort to harness neuroscience in a way that might better prepare soldiers for the mental rigors of modern warfare.

In a series of small business solicitations released last week, the Office of the Secretary of Defense outlined plans for a new “Cognitive Readiness Technology” program with the aim of “making our warfighters as cognitively strong as they are physically strong.”[more]

Pentagon Scientists Inject Necks to ‘Cure’ PTSD

Finding an effective treatment for post-traumatic stress disorder has been a top Pentagon priority for years. And with an estimated one in five veterans from Iraq and Afghanistan suffering from PTSD, the military’s been willing to consider anything and everything, including yoga, dog therapy and acupuncture, to alleviate symptoms.

But a small new study out of Walter Reed Army Medical Center might offer more than temporary relief — with nothing more than a quick jab to the neck. [more]

University of Oxford scientists look for biological roots of religion:

“There is a lot of evidence that religious beliefs flow very naturally from the way the mind is designed,” Dr. Shackelford says. It has long been believed, he says, that atheism is a harder position to maintain because it goes against the natural instinct to want to attach some kind of meaning to phenomena we can’t explain. “Perhaps religion is natural, but not inevitable.” [via GlobeAndMail.com]

A research collaboration led by biologists and neuroscientists at the University of Pennsylvania has found a molecular pathway in the brain that is the cause of cognitive impairment due to sleep deprivation. Just as important, the team believes that the cognitive deficits caused by sleep deprivation, such as an inability to focus, learn or memorize, may be reversible by reducing the concentration of a specific enzyme that builds up in the hippocampus of the brain [via ScienceDigest].

Mobilizy, the company from Salzburg, that brought us one of the world’s first Augmented Reality browsers, Wikitude, just released a major upgrade which crosses that significant line between technology and its effects in the ‘real’ world. Their idea was to build a virtual memorial in remembrance of the 9/11 attacks in the U.S. and the destruction of the World Trade Center in New York City. The result will be the ability to point their Android and iPhone application at the place where the World Trade Center once stood and witness a 3D rendering of the Twin Towers, once more.

UCLA researchers explore the SCARF dynamic [status, certainty, autonomy, relatedness, and fair treatment], how high intelligence often corresponds with low self-awareness, and how attempts to hide feelings often trigger threat responses [via Strategy+Business]:

Eisenberger’s fellow researcher Matthew Lieberman, also of UCLA, hypothesizes that human beings evolved this link between social connection and physical discomfort within the brain “because, to a mammal, being socially connected to caregivers is necessary for survival.” This study and many others now emerging have made one thing clear: The human brain is a social organ. Its physiological and neurological reactions are directly and profoundly shaped by social interaction. Indeed, as Lieberman puts it, “Most processes operating in the background when your brain is at rest are involved in thinking about other people and yourself.”

This presents enormous challenges to managers. Although a job is often regarded as a purely economic transaction, in which people exchange their labor for financial compensation, the brain experiences the workplace first and foremost as a social system. Like the experiment participants whose avatars were left out of the game, people who feel betrayed or unrecognized at work — for example, when they are reprimanded, given an assignment that seems unworthy, or told to take a pay cut — experience it as a neural impulse, as powerful and painful as a blow to the head. Most people who work in companies learn to rationalize or temper their reactions; they “suck it up,” as the common parlance puts it. But they also limit their commitment and engagement. They become purely transactional employees, reluctant to give more of themselves to the company, because the social context stands in their way.

Augmented Reality layers data on physical space to enhance our ability to see richness that is there but often hidden. Applications for marketing, gaming, education and entertainment are obvious. But can AR help us improve the planet as well? [via Mariamz]:

We move faster and faster in our cyber age, all knowing, ever-connected, always-on. Augmented reality beckons: the devices in our pockets become more powerful and our ability to connect digitally everywhere excites and exhilarates whilst pushing the odd few over the edge into internet rehab. Yet something else is happening scarily fast, something only the most obstinate dare deny.

Another step closer to the bionic brain [via ScienceDaily]:

A model that replicates the functions of the human brain is feasible in 10 years according to neuroscientist Professor Henry Markram of the Brain Mind Institute in Switzerland. “I absolutely believe it is technically and biologically possible. The only uncertainty is financial. It is an extremely expensive project and not all is yet secured.”

Bionic medicine continues to evolve as a potential treatment or cure for paralysis, deafness, blindness, Parkinson’s disease, epilepsy and more [see full article in New Scientist].

For example, Eberhard Fetz’s lab at the University of Washington in Seattle is testing:

a new treatment that might one day cure paralysis, which is typically caused by a broken connection in the spinal cord. Though much work has focused on using stem cells to regrow damaged nerve fibres, some researchers believe that an electronic bypass like this is equally viable.

The idea is to implant electronic chips in the relevant regions of the brain to record neural activity. Then a decoder deciphers the neural chatter, often from thousands of neurons, to figure out what the brain wants the body to do. These messages must then be relayed - ideally wirelessly - to electrodes that deliver a pulse of electricity to stimulate the muscles into action. Such “brain chips” are already restoring hearing to the deaf and vision to the blind, and helping to stave off epileptic fits, so the idea isn’t as far-fetched as it might sound.

Drew Conway has a review of the July 2009 issue of Science dedicated to Network Science [via Zero Intelligence Agents]:

The currently issue of Science magazine is entirely dedicated to networks and network science. The issue is packed with interesting articles, and is certain must-read for anyone studying or working with networks. The editors of Science have done well in capturing the breadth of disciplines and interests studying networks. One article that I will not cover in detail but recommend to all readers is Carter Butt’s “Revisiting the Foundation of Network Analysis,” where he discusses what is, and more appropriately, what is not network analysis, and how the science got here.

The article discussing network analysis and national security, in fact, is an excellent example of the wide audience for this topic; however, the thesis of the piece was rather disappointing. In “Counterterrorism’s New Tool: ‘Metanetwork’ Analysis“, we we hear from a veritable who’s-who in the national security/network analysis space. Starting with those on the technology front at Palantir Technologies (the same software we used from Project Grey Goose), to well respected practitioners in academia, business and government such as Marc Sageman, Valdis Krebs and Kathleen Carley, among many others. The article discusses where networks have helped, but also possibly hurt U.S. couterterrorism efforts, which made its focus on so called metanetwork analysis confusing.

In short, metanetworks are simple multiple layers of networks; that is, in any given space there will be a layer of social structure as well as physical (roads and waterways), infrastructure (power and communication), exchange (financial), etc. Metanetwork analysis attempts to examine this complex system as a whole in order to examine how activity on one layer can affect the others, and vice a versa. In theory, this is very appealing, however, in practice this method fails in two major ways.

Careers and research in Network Science are also increasing to the point where physicist Albert-László Barabási says, “I’m unable to keep up” [via sciencecareers.com]:

What unites the sociologists, physicists, biologists, and other scientists studying networks is the recognition that “whether they’re networks of people, computers, genes, [or] neurons, they often obey similar mathematical rules and have similar properties,” says Nicholas Christakis, a professor of sociology and of medical sociology at Harvard Medical School in Boston….

The National Science Foundation, too, has been increasing its support for network science, especially within the divisions dedicated to computer science and human social dynamics. There is also growing military support for network research, Barabási says, pointing to research programs funded by the Army, Air Force, Office of Naval Research, and Defense Threat Reduction Agency. “There’s never enough money, of course,” he says. “But we’re seeing that many agencies are discovering that this is important, and they’re putting their money where their mouth is.”

Website of Media Destruction has an excellent article on how new media is changing the role of government with reference to William Gibson’s 2003 op-ed for the NYT:

Orwell’s projections come from the era of information broadcasting, and are not applicable to our own. Had Orwell been able to equip Big Brother with all the tools of artificial intelligence, he would still have been writing from an older paradigm, and the result could never have described our situation today, nor suggested where we might be heading.

That our own biggish brothers, in the name of national security, draw from ever wider and increasingly transparent fields of data may disturb us, but this is something that corporations, nongovernmental organizations and individuals do as well, with greater and greater frequency. The collection and management of information, at every level, is exponentially empowered by the global nature of the system itself, a system unfettered by national boundaries or, increasingly, government control.

It is becoming unprecedentedly difficult for anyone, anyone at all, to keep a secret.

In the age of the leak and the blog, of evidence extraction and link discovery, truths will either out or be outed, later if not sooner. This is something I would bring to the attention of every diplomat, politician and corporate leader: the future, eventually, will find you out. The future, wielding unimaginable tools of transparency, will have its way with you. In the end, you will be seen to have done that which you did. (Emphasis mine)

Researchers at Princeton discover correlations between cognitive skills, economic preferences and strategic behavior [via Proceedings of the National Academy of Sciences of the USA]:

Economic analysis has so far said little about how an individual’s cognitive skills (CS) are related to the individual’s economic preferences in different choice domains, such as risk taking or saving, and how preferences in different domains are related to each other. Using a sample of 1,000 trainee truckers we report three findings.

First, there is a strong and significant relationship between an individual’s CS and preferences. Individuals with better CS are more patient, in both short- and long-run. Better CS are also associated with a greater willingness to take calculated risks.

Second, CS predict social awareness and choices in a sequential Prisoner’s Dilemma game. Subjects with better CS more accurately forecast others’ behavior and differentiate their behavior as a second mover more strongly depending on the first-mover’s choice.

Third, CS, and in particular, the ability to plan, strongly predict perseverance on the job in a setting with a substantial financial penalty for early exit.

Consistent with CS being a common factor in all of these preferences and behaviors, we find a strong pattern of correlation among them. These results, taken together with the theoretical explanation we offer for the relationships we find, suggest that higher CS systematically affect preferences and choices in ways that favor economic success.

Researchers at the University of Pannonia, Hungary demonstrate how sparrrows solve problems more quickly as a group than as individuals [via scienceblogs]:

Liker and Bokony’s sparrow experiments are the first to show that large animal groups outperform smaller ones at problem-solving tasks where they have to invent new techniques. House sparrows are a good choice for a study like this. They are very social birds that live in flocks of anywhere from a few individuals to a few hundred. They are opportunists that use their relatively large brains to find food in all sorts of new environments.

“That may be so, however, new scientific studies across several animal species, including humans, are challenging the notion that brain size alone is a measure of intelligence. Rather, scientists now argue, it is a brain’s underlying organization and molecular activity at its synapses (the communication junctions between neurons through which nerve impulses pass) that dictate intelligence.” [via Scientific American]

New research from Brigham Young University on collaboration reveals that diverse groups are more effective problem solving even though they believe they aren’t [via Newswise]:

The experiment also revealed a fallacy in the assumptions we make about our own effectiveness in groups. The subjects in the experiment were members of different fraternities and sororities. In general, when the newcomer was from the same sorority or fraternity as the other team members, the group reported that it worked well together, but was less likely to correctly solve the problem.

In contrast, when the newcomer was a member of a rival sorority or fraternity, the opposite was true — these groups felt they worked together less effectively, yet they significantly outperformed socially homogenous groups.

“What’s really distinct about this research is that, from a self-reporting perspective, what people perceive to be beneficial turns out to be dead wrong, Liljenquist says. “The teams that felt they worked least effectively together were ironically the top performers!”
