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

A knowing glance. A paw on your arm. A lick on the cheek. Most dog owners can recall a time when they were feeling down. And somehow, their dog just knew something was wrong and responded with a loving gesture.
Many dog lovers have long believed that canines are able to sense human emotions. And, a growing body of evidence on the emotional connection between man and his best friend adds weight to these heart ...read more

When researchers edit genes with CRISPR today, their systems chop a strand of DNA in half before inserting a new gene and allowing a cell's natural healing mechanisms to patch the strand back up.
That technique works well overall, but it can lead to errors, and the success rate varies depending on the type of cell. Scientists have been on the hunt for better versions of CRISPR for years.
Now, a new protein that can insert custom genes into DNA witho ...read more
