Worldwide, people drink over 65 billion gallons of alcohol each year. The United States’ share, if divided equally across the adult population, would amount to about two and a half gallons of pure alcohol per person, annually.

That’s the idea behind the “drunken monkey&rdquo ...read more
Two galaxy clusters, Abell 0399 and Abell 0401, are merging about 1 billion light-years from Earth. This image shows the clusters' cores (red) in X-ray-light. The two are linked by a thin filament (yellow and blue), which glows faintly in microwaves and radio waves.

Galaxy clusters are a great place to peer in on the physics that govern our universe. Not only are these cosm ...read more

Since 2004, the rate of death by suicide has exceeded that of death by combat injury for American soldiers. A review of more than 100 cases involving the suicide of an active-duty soldier found a significant association between firearm ownership, access and usage patterns and increased risk of suicide.
The study, published today in the open-access, online-only journal JAMA Network Open, conducted psychological autopsies of 135 U.S. soldiers who committed ...read more

NASA astronaut Scott Kelly spent a year in space while scientists monitored changes in his body, as well as that of his twin, Mark Kelly, who remained on the ground. Kelly came back to Earth in good shape, the experiment showed. And, some Russian cosmonauts have also spent even longer than Kelly in space without obvious long term ill effect from ...read more
