First came the joystick. Then came the motion-sensing Wii remote. Now get ready for another radical and rather unsettling leap in video games technology: thought control.

Satoru Iwata, the president and chief executive of Nintendo - which is expected to sell about 25million units of its successful Wii video games console this financial year - has no doubts about the next gaming boom. “As soon as we think something in our brain, it will appear within a video game,” he told The Times in an exclusive interview.

“You'll probably need to wear some kind of hat or helmet or something.”

As far-fetched as it sounds, Mr Iwata's claim - which brings to mind the plot of Craig Thomas's bestselling 1977 novel Firefox, about a mind-reading Soviet fighter aircraft - is already coming true: the world's first thought-controlled game is expected to be launched by the Sydney company Emotiv by the end of this year.

The social psychology revolution is reaching its tipping point

Go and look in your bookshop: new thinking is seeping into politics

It took a long time. Longer than it should have. But in the end, the penny dropped.

Back in the 1980s, Tony Blair, a junior Shadow minister, was sitting quietly with his constituency agent, John Burton, when he suddenly exclaimed: “You know, John, I understand it all. Finally, I've got it.” When Burton asked him what he was talking about, Blair triumphantly replied: “Microeconomics!”

I wonder whether in a couple of decades' time, our own fumbling first acquaintance with new thinking will appear similarly amusing. For an intellectual revolution is under way that will change the way we think about public policy just as the free market economists did in the 1980s. I wonder whether one day soon a future party leader will turn round to his agent and say: “Finally, I've got it! Human behaviour.”

Those who doubt that there is something going on in the world of ideas should get themselves a publisher's catalogue

Future Human: The Evolution of Immediate Emotion

Fri, 18 Jul 2008 11:23:56 GMT

clipped by: wildcat
clipper's remarks: Humans, apparently, are still in the early stages of evolving extended response mechanisms. But it seems likely that by the time we portion more of our brain to long-term dangers, there will be few grizzly bears around to worry about, and a whole lotta global warming.

Why a grizzly gets you shivering—but not global warming

In my Science Confirms the Obvious post today, I discussed the first psychological proof (so say the authors) that humans can indeed experience emotions without immediately knowing why. We do this, they say, because we evolved that way. True, scientists love that explanation, but here it’s quite intriguing.

“After all, you are likely to live longer if you immediately stop moving at the sight of a growling grizzly bear,”

“and do not need full awareness for such a response to be instigated.” Given the flood of unexpected stimuli we face moment to moment, quick reactions make sense for survival.

You, that bear, and other animals experience emotions such as fear, anger, or disgust. But only a few species are aware of their emotions. This ability helps humans judge and respond to the behavior of others in order to navigate social situations and, ultimately, grease the wheels of complex society.

Addicted to Grief?

clipper's remarks: When time doesn't heal, the brain's reward system may be playing a role

Clip Source: www.sciam.com

Losing a loved one is always painful, but for most people time eventually heals the wounds. For about 10 to 20 percent of the bereaved, however, accepting and getting over a loss remains extremely difficult, even years later. Now researchers have come a step closer to elucidating the neurobiological underpinnings of this condition called complicated grief (CG). A new functional magnetic resonance imaging (fMRI) study, published online in May in the journal NeuroImage, shows that in CG patients reminders of the deceased activate a brain area associated with reward processing, pleasure and addiction.

While in the scanner, the women saw pictures and words that reminded them of their loved one. Brain networks associated with social pain became activated in all women, but in the CG patients reminders of the deceased also excited the nucleus accumbens, a forebrain area most commonly associated with reward.

$3 billion super soldier program: 10 times muscle endurance, 7 foot vertical leap, wall crawling, personal flight and more

DARPA today has a long-term, $3 billion program to help make such a “Metabolically Dominant Soldier.” In other words, the military is studying how to use technology and biology to meld man and machine and transcend the limits of the human body. Described the project director, “My measure of success is that the International Olympic Committee bans everything we do" The $3 billion program is definitely trying to achieve transhuman performance goals.

The wearable gear would enable running at 100 meter olympic sprinter speed for hours and the 7 foot vertical leap, the wall crawling, personal flight, invisibility, greatly enhanced strength, better body armor and carrying bigger and more powerful weapons.

The drugs and genetic enhancements and some technology which gets applied would allow for regeneration, faster healing

Is the Internet Bad for Science?

clipper's remarks: as always, the answer depends on the person, in this case, who is the scientist doing the research.

Using the internet to search for scientific articles is bad for researchers, says University of Chicago sociologist James Evans in an article published today in Science.

His argument is a classic computer-versus-paper library dilemma, updated for science: when researchers search online, they tend to arrive at just a few high-ranking articles. Lost is the breadth of scholarship encountered by old-fashioned, page-turning browsing.

"As more journal issues came online, the articles referenced tended to be more recent, fewer journals and articles were cited, and more of the citations were to fewer journals and articles," writes Evans, who analyzed the citation patterns of 34 million journal articles that went online between 1998 and 2005.

He conclues, "The forced browsing of print archives may have stretched scientists and scholars to anchor findings deeply into past and present scholarship

LONDON, England (CNN) -- A group of experts from around the world will Thursday hold a first of its kind conference on global catastrophic risks.

They will discuss what should be done to prevent these risks from becoming realities that could lead to the end of human life on earth as we know it.

Speakers at the four-day event at Oxford University in Britain will talk about topics including nuclear terrorism and what to do if a large asteroid were to be on a collision course with our planet.

On the final day of the Global Catastrophic Risk Conference experts will focus on what could be the unintended consequences of new technologies, such as superintelligent machines that, if ill-conceived, might cause the demise of Homo sapiens.

"Any entity which is radically smarter than human beings would also be very powerful,"

said Dr. Nick Bostrom

"If we get something wrong, you could imagine the consequences would involve the extinction of the human species."

Passive learning imprints on the brain just like active learning

It's conventional wisdom that practice makes perfect. But if practicing only consists of watching, rather than doing, does that advance proficiency? Yes, according to a study by Dartmouth researchers.

In a study titled "Sensitivity of the Action Observation Network to Physical and Observational Learning" published in the journal Cerebral Cortex in May 2008, Dartmouth researchers determined that people can acquire motor skills through the "seeing" as well as the "doing" form of learning.

"It's been established in previous research that there are correlations in behavioral performance between active and passive learning, but in this study we were surprised by the remarkable similarity in brain activation when our research participants observed dance sequences that were actively or passively experienced,"

The study focused on the Action Observance Network (AON) in the brain

Hunger Can Make You Happy

clipper's remarks: The researchers think that hunger-induced happiness is an adaptive measure. Getting food, especially in the wild, requires concentration, clear-headed perception and often cooperation.

Contrary to the moans of many dieters, being hungry may make you happy. Or, at least, it can be a serious motivator whose evolutionary intent was to help you find dinner instead of becoming dinner.

When our bodies notice we need more calories, levels of a hormone called ghrelin increase. Ghrelin is known to spur hunger, but new research suggests this may be a side effect of its primary job as a stress-buster.

Researchers manipulated ghrelin levels in mice through a variety of methods, including prolonged calorie restriction, ghrelin injection and a genetic modification rendering the mice numb to ghrelin’s effect.

Mice who had limited ghrelin activity seemed depressed. If pushed into deep water they made no effort to swim. When introduced to a maze, they clung to the entryway. And when placed with other mice, they tended to keep to themselves. (These behaviors were reversed when the mice were given a low-dose antidepressant commonly prescribed to humans.)

When can empathy move us to action?

Mon, 14 Jul 2008 13:41:31 GMT

clipped by: wildcat
clipper's remarks: And so cognitive empathy alone is not enough. We also need what Ekman calls "emotional empathy"—when you physically feel what other people feel, as though their emotions were contagious. This emotional contagion depends in large part on cells in the brain called mirror neurons, which fire when we sense another's emotional state, creating an echo of that state inside our own minds. Emotional empathy attunes us to another person's inner emotional world, a plus for a wide range of professions, from sales to nursing—not to mention for any parent or lover.

We often emphasize the importance of keeping cool in a crisis. But sometimes coolness can give way to detachment and apathy.

We saw a perfect example of this in the response to Hurricane Katrina, whose devastation was amplified enormously by the lackadaisical response from the agencies charged with managing the emergency. As we all witnessed, leaders at the highest levels were weirdly detached, despite the abundant evidence on our TV screens that they needed to snap to action. The victims' pain was exacerbated by such indifference to their suffering. So as we prepare for the next Katrina-like disaster, what can the science of social intelligence—especially research into empathy—teach policy makers and first responders about the best way to handle themselves during such a crisis?

The differences between these forms of empathy highlight the challenges we face in responding to other people's pain. But they also make clear how the right approach can move us to compassionate action.

The Anthropic Principle

Has the universe developed for the express purpose of being observed and understood by intelligent beings, or is it just a lucky break for the intelligent beings that they exist at all?

The Anthropic Principle was proposed in Poland in 1973, during a special two-week series of synopsia commemorating Copernicus’s 500th birthday. It was proposed by Brandon Carter, who, on Copernicus’s birthday, had the audacity to proclaim that humanity did indeed hold a special place in the Universe, an assertion that is the exact opposite of Copernicus’s now universally accepted theory.

Carter was not, however, claiming that the Universe was our own personal playground, made specifically with humanity in mind. The version of the Anthropic Principle that he proposed that day, which is now referred to as the Weak Anthropic Principle (WAP) stated only that by our very existence as carbon-based intelligent creatures, we impose a sort of selection effect on the Universe

Research identifies brain cells related to fear

The National Institute of Mental Health estimates that in any given year, about
40 million adults (18 or older) will suffer from some form of anxiety disorder, including debilitating conditions such as phobias, panic disorders and post-traumatic stress disorder (PTSD). It is estimated that nearly 15 percent of U.S. soldiers returning from Iraq and Afghanistan develop PTSD, underscoring the urgency to develop better treatment strategies for anxiety disorders. These disorders can lead to myriad problems that hinder daily life – or ruin it altogether – such as drug abuse, alcoholism, marital problems, unemployment and suicide.

Functional imaging studies in combat veterans have revealed that the amygdala, a cerebral structure of the temporal lobe known to play a key role in fear and anxiety, is hyperactive in PTSD subjects.

Life's Increasing Complexity Spurred Evolution of Human Brain

Whether it be a week ago, or a couple of thousand years ago, humans have always needed split second thinking to avoid life threatening situations. Whether it would be a sudden and cataclysmic encounter with a semi-truck, or a similar encounter with a disgruntled lion, quick thinking has always been necessary.

But we don’t always need split second thinking; sometimes we just need to take in all the information, and process it. Slowly.

According to new research from the University of Bristol, lead by Pete Trimmer, and published Tuesday in the Proceedings of the Royal Society B., those two types of thinking are completed by two separate areas of our brains.

For a long time scientists have believed that mammals have two decision making systems in their brains, each one operating at different speeds depending on the situation around them. Trimmer’s research shows that the older, more instinctual and thus less accurate thinking may have helped shape the more recent, methodical thinking.

Ordinary into Genius- Genes

Scientists Identify Genes that Could Turn Ordinary People into Supergeniuses (or Mindless Drones)

It's clear that there's a specific set of genes responsible for brain development when you're in the womb, and that those genes affect your ability to learn later on. But now a group of researchers in the U.S. and Canada have identified those genes. And their discovery could represent the first step in tweaking brain development. It's possible that that knocking out some of those genes or adding extra copies of them to a developing baby could result in the tailor-made human minds of Brave New World: Some will be born to develop cutting-edge technologies, and others to be slow-witted and compliant.

Published this weekend in PLoS Genetics, the study is extraordinary not just because of its futuristic implications, but because of the cool new super-rapid system the researchers used to identify which genes are active during brain development. The technique is called RNA interference, or RNAi:
