The smarter the person, the faster information zips around the brain, a UCLA study finds. And this ability to think quickly apparently is inherited.
The study, published in the Journal of Neuroscience, looked at the brains and intelligence of 92 people. All the participants took standard IQ tests. Then the researchers studied their brains using a technique called diffusion tensor imaging, or DTI.
Scientists looking for signs of life in the universe -- as well as another planet like our own -- are a lot closer to their goal than people realize.
That was the consensus of a panel on the search for life in the universe held at NASA headquarters Monday in Washington. The discussion focused not only on the philosophical question of whether we're alone in the universe but also on the technological advances made in an effort to answer that question.
"We believe we're very, very close in terms of technology and science to actually finding the other Earth and our chance to find signs of life on another world," said Sara Seager, a MacArthur Fellow and professor of planetary science and physics at the Massachusetts Institute of Technology.
