We worry because we are built to anticipate the future. Nothing can stop us from worrying, but science can teach us how to worry better, and when to stop worrying.
Light from the very first stars in the universe has been measured – and there is less of it than previously thought. The discovery should help us better understand how the hot haze of hydrogen that existed shortly after the big bang transformed into the complex web of stars and galaxies we see today. Although…
Yoga has positive effects on mild depression and sleep complaints, even in the absence of drug treatments, and improves symptoms associated with schizophrenia and ADHD in patients on medication, according to a systematic review of the exercise on major clinical psychiatric disorders. Published in the open-access journal, Frontiers in Psychiatry, the review of more than…
Astronomers have seen a distant galaxy that blasts away material with two trillion times the energy the sun emits — the biggest such eruption ever seen. That ejection of matter could answer an important question about the universe: why are the black holes in the centers of galaxies so light? Computer models of the early…
All but about 50 of hundreds of research chimpanzees belonging to the National Institutes of Health should be retired to the national sanctuary in northwest Louisiana, and all of them should have plenty of room to play and climb, an NIH committee has recommended. The NIH Council of Councils Working Group approved the proposal, which…
The world is depleting underground water reserves faster than they can be replenished due to over-exploitation, according to scientists in Canada and the Netherlands. The researchers combined groundwater usage data from around the globe with computer models of underground water resources to come up with a measure of water usage relative to supply. That measure…
Humans share over 90% of their DNA with their primate cousins. The expression or activity patterns of genes differ across species in ways that help explain each species’ distinct biology and behavior. DNA factors that contribute to the differences were described at the American Society of Human Genetics 2012 meeting in a presentation by Yoav…
