Better Asleep Than Awake

After decades of careful observation, scientists have figured out that there are a few things we do better when we're sleeping than when we're awake. Dealing with stress is one.

Most neuroscientists agree that sleep is when we organize memories for long-term storage. People whose sleep is disturbed after studying have far more imperfect recall than people who get a good eight hours of shuteye. But a study published a couple of weeks ago shows that you can use simple memory reinforcement techniques while you're sleeping that will make your recall better than average. ... What our brains do while we sleep has a lot to do with how well we remember what we've done while we're awake.

While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.

Why we're so self-critical of ourselves after meeting someone new

A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.

Surprising Science

We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.

NASA launches ICESat-2 into orbit to track ice changes in Antarctica and Greenland

Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.

Firing three pairs of laser beams 10,000 times per second, the ICESat-2 satellite will measure how long it takes for faint reflections to bounce back from ground and sea ice, allowing scientists to measure the thickness, elevation and extent of global ice

Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
