Mimicking how the brain recognizes street scenes

...aving an impact on computer science and artificial intelligence (AI). For the first time, scientists in Tomaso Poggio's laboratory at the McGovern Institute for Brain Research at MIT applied a computational model of how the brain processes visual information to a complex, real world task: recognizing the objects ...

Common gene version optimizes thinking -- but with a possible downside

...ation, affecting a range of functions from general intelligence to attention. Three fourths of subjects studied had at least one copy of the version that results in more efficient filtering of information processed by the brain's executive hub, the prefrontal cortex. However, the same version was also more pr...

Study shows hope for early diagnosis of Alzheimer's

The teams conducted several experiments, ultimately evaluating the par...

Brightsmith spent several months recently in the Amazon rain forests of eastern Peru, where he runs a long-term macaw research project. He has learned that one reason the macaw populations are declining is du...

When nerve cells can't make contact

...l disability. Autistic individuals exhibiting high intelligence or outstanding skills in a particular area, called "savants", such as the main character in the film "Rain Man", are rare. Even up to the middle of the last century, exceptionally cold emotional behaviour on the part of the mother was given as the ...

3-D ultrasound scanner could guide robotic surgeries

...te lesions suspected to be cancer. As artificial intelligence technology improves in the coming decades, the scanner might even be able to guide surgical robots without the help of a surgeon, the researchers said. The 3-D ultrasound probe has yet to be tested in human patients, Smith said, but he added that h...

Robots manipulating animal behaviour

...uxelles, the project had its origins in collective intelligence and behaviour in animal society, as well as the tradition of using artificial agents to test theories about animals. "Robots have already been used to interact with some animals, such as bees. But they cannot react to the animals' response," he says....

Study finds 60 new genes controlled by DNA snippet

"Junk DNA" No More Genes are the chains of deoxyribonucleic acids (DNA) that encode instructions for the building of proteins, the workhorses that make up ...

Newly discovered killer cell fights cancer

"In the same way that intelligence and law enforcement agencies can face deadly threats together instead of separately, this one cell combines the ability to kill foreign pathogens and distribute information about that experience," says Drew Pardoll, M.D., Ph.D., the Seraph Professor ...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

"These findings," she says, "give a new meaning to 'a healthy mind in a healthy body'. They show that we rely on our immune system to maintain brain fun...
