Children with autism see simple movements twice as fast as other children their age, a new study finds.
Researchers at Vanderbilt University and the University of Rochester were looking to test a common theory about autism which holds that overwhelming sensory stimulation inhibits other brain functions. The researchers figured they could check that by studying how kids with autism process moving images.
Earth's atmosphere is entering a new era. A mountaintop research station that has been tracking carbon dioxide for more than 50 years says the level of that gas in our air has reached a milestone: 400 parts per million.
That number is one of the clearest measures of how human beings are changing the planet. It shows how much carbon we have put into the air from burning fossil fuels — and that carbon dioxide drives global warming.
This measurement comes from Mauna Loa, Hawaii, a remote volcano where the air is largely free of local influences.
The SETI (Search for Extraterrestrial Intelligence) Institute's Jill Tarter has spent decades searching for the signals that would tell us we aren't alone in the cosmos. Tarter discusses the hunt, and what the presence of intelligent life elsewhere might tell us about our own future on Earth.
David Matsumoto, a psychology professor at San Francisco State University, trains national security officials and police officers to recognize "microexpressions"--fleeting, split-second flashes of emotion across someone's face. Matsumoto says those subtle cues may reveal how an interview subject is feeling, helping officials to hone their line of questioning.
