No, German Scientists Have Not Confirmed the “Impossible” EMDrive

Two German researchers claim they have produced measurable amounts of thrust using a copy of NASA’s controversial EMDrive. It’s a result that has many people talking, but don’t plan your trip to the to the Alpha Centauri system just yet—the experts we spoke with are all highly skeptical of the study and its findings. » 7/28/15 1:59pm Tuesday 1:59pm

This Shower of Gamma Rays Is from a Flaring Blazar 5 Billion Years Ago

Five billion years ago, a blazar abruptly flared, triggered an intense rain of gamma rays. Racing across the universe for millennia, they finally slammed into NASA’s Fermi satellite over several days this June, setting a new record for the most luminous high-energy object we’ve ever seen. » 7/12/15 1:40pm 7/12/15 1:40pm

How Bigger Atoms Could Help Make Smaller “Lab-on-a-Chip” Devices

“Lab-on-a-chip” devices – which can carry out several laboratory functions on a single, micro-sized chip – are the result of a quiet scientific revolution over the past few years. For example, they enable doctors to make complex diagnoses instantly from a single drop of blood. » 7/01/15 3:30am 7/01/15 3:30am

We May Have Dramatically Misunderstood the Shapes of Black Holes

Even if you didn’t see Interstellar, you’ve probably heard about how black holes have an “event horizon” — and once you pass it, you’re mashed into multi-dimensional mush. But now, some physicists believe we got it all wrong. Black holes are more like fuzzy balls of cotton, with no event horizons at all. » 6/24/15 4:30pm 6/24/15 4:30pm

Physicists Just Cooled Molecules to a Hair Above Absolute Zero

Many scientists say that reaching absolute zero is a lot like traveling at the speed of light: impossible. Well, some MIT scientists almost pulled a Doc Brown and got a lot closer to the impossible goal by cooling a molecule to 500 nanokelvins. That’s just above absolute zero and about a million times colder than… » 6/16/15 1:20pm 6/16/15 1:20pm
