"This is a capacity that everyone thought was uniquely human, but we've found evidence that some animals can keep a beat." -- Adena Schachner, Harvard University

The team of researchers [...] studied connection patterns in the BitTorrent file-sharing network — one of the largest and most popular P2P systems today. They found that over the course of weeks, groups of users formed communities where each member consistently connected with other community members more than with users outside the community. [...] Given the impact of this threat, the researchers developed a technique that prevents accurate classification by intelligently hiding user-intended downloading behavior in a cloud of random downloading.

U.K. researchers found that children with Asperger syndrome (AS) do not experience the normal twofold increase of cortisol upon waking up. Levels of the hormone in their bodies do continue to decrease throughout the day, though, just as they do in those without the syndrome.

A science-savvy robot called Adam has successfully developed and tested its first scientific hypothesis, all without human intervention. This hints at a future where robots could spare lab assistants and post-docs some of the drudgery of research.

Melbourne University's Dr Brent Coker says workers who surf the internet for leisure, known as 'Workplace Internet Leisure Browsing' (WILB), are more productive than those who don't. [...] "People who do surf the internet for fun at work - within a reasonable limit of less than 20 per cent of their total time in the office - are more productive by about nine per cent than those who don't," said Dr Coker, from the university's Department of Management and Marketing.

The first age at which there was any marked decline was at 27 in tests of brain speed, reasoning and visual puzzle-solving ability.

Things like memory stayed intact until the age of 37, on average, while abilities based on accumulated knowledge, such as performance on tests of vocabulary or general information, increased until the age of 60.

The researchers claim that a market economy, where inventors buy and sell shares of the key elements of their discoveries, beats the winner-takes-all patent system, especially in terms of the number of beneficiaries, levels of collaboration and pace of development.

When asked to describe the scenes in speech, the speakers used the word orders typical of their respective languages. [...] But when asked to describe the same scenes using only their hands, all of the adults, no matter what language they spoke, produced the same order –– subject, object, verb (woman knob twists).

Indeed, Stair represents a new wave of AI, one that integrates learning, vision, navigation, manipulation, planning, reasoning, speech and natural-language processing. It also marks a transition of AI from narrow, carefully defined domains to real-world situations in which systems learn to deal with complex data and adapt to uncertainty.
