Many marathon runners know the boost that can come from popping a mid-race energy gel. (Mmmm, calorie-rich goop.) But according to new research published in Science Advances, when it comes to endurance events, there’s a limit to how much energy th ...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
Recent analysis of Planck data upholds mysteries that have existed since the spacecraft’s first results in 2013. (Credit: ESA/Planck Collaboration)
During its time in orbit, the European Space Agency's Planck spacecraft gave humanity the most sophisticated measurements ever made of the cosmic microwave background (CMB) radiation, the first flash of light that rippled across the universe after the Big Bang. Plank told us the shape of the universe and confirmed crucial components of the B ...read more
Though researchers don't know why methane levels are currently rising, the fossil fuel industry was likely to blame in the past. (Credit: Nick Stubbs/Shutterstock)
Carbon dioxide is climate change’s villainous star. But methane, an even more potent greenhouse gas, is CO2’s lesser-known evil twin. Researchers now find methane levels in the atmosphere are on an escalating upward trend. That’s a problem because emission scenarios that limit global warming to 2 degrees Celsius a ...read more
