Nine-Spined Strickleback: A Small Fish That Has The Ability To Learn

A nine-spined stickleback fish

A small fish found in streams across Europe has a human-like ability to learn, British scientists reported Wednesday.

The nine-spined stickleback could be the first animal to exhibit a key human social learning strategy that allows it to compare the behavior of others to its own experience and make choices that lead it to better food supplies.

Learning With Robot-Aided Therapy

Learning With Robot-Aided Therapy 

A robot named Cosmo has become six-year-old Kevin Fitzgerald’s unlikely ally in his uphill everyday battle with developmental difficulties.

At a strip mall clinic in suburban Maryland, Kevin is at the unlikely intersection of new efforts to treat symptoms of autism, cerebral palsy and other developmental disorders with robotics and computer work.

The Human Brain Lives ‘On The Edge Of Chaos’

The Human Brain Lives ‘On The Edge Of Chaos’

 

Cambridge-based researchers provide new evidence that the human brain lives “on the edge of chaos”, at a critical transition point between randomness and order. The study, published March 20 in the open-access journal PLoS Computational Biology, provides experimental data on an idea previously fraught with theoretical speculation.

Why Is Crying Beneficial?

Why Is Crying Beneficial? 

We’ve all experienced a “good cry”-whether following a breakup or just after a really stressful day, shedding some tears can often make us feel better and help us put things in perspective. But why is crying beneficial? And is there such a thing as a “bad cry”? University of South Florida psychologists Jonathan Rottenberg and Lauren M. Bylsma, along with their colleague Ad J.J.M. Vingerhoets of Tilburg University describe some of their recent findings about the psychology of crying in the December issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science.

Children Learn Differently After 12 Years Of Age

Children Learn Differently After 12 Years Of Age 

Eight-year-old children have a radically different learning strategy from twelve-year-olds and adults. Eight-year-olds learn primarily from positive feedback (‘Well done!’), whereas negative feedback (‘Got it wrong this time’) scarcely causes any alarm bells to ring. Twelve-year-olds are better able to process negative feedback, and use it to learn from their mistakes. Adults do the same, but more efficiently.

20% of Scientists Take Drugs to Boost Brain Power

20% of Scientists Take Drugs to Boost Brain Power

“Brain drugs” are common among scientists

Twenty percent of scientists admit to using performance-enhancing prescription drugs for non-medical reasons, according to a survey released Wednesday by Nature, Britain’s top science journal. The overwhelming majority of these med-taking brainiacs said they indulged in order to “improve concentration,” and 60 percent said they did so on a daily or weekly basis.
