A brief bout of insomnia can be maddening. You know what it feels like. We all do. Lying awake chasing feverish thoughts from our minds while the slow tick of passing minutes compounds sleep-stealing anxiety.
For most of us these episodes are a brief interruption to our sleep schedules. Others experience more persistent insomnia, but at a level that's often manageable. But for a very rare group of people with a frightening disease called fatal fami ...read more

Soviet cosmonaut Alexei Leonov, the first
person to walk in space, has died at the age of 85 at the Burdenko Military
Hospital in Moscow. His death was announced Friday, Oct. 11, by Roscosmos,
Russia’s space agency.
Born in 1934, Leonov became the eleventh Soviet
cosmonaut and achieved major milestones of space exploration. During the
Voskhod 2 mission, on March 18, 1965, he exited his capsule ...read more

In the 2014 movie Interstellar, astronauts investigate planets orbiting a supermassive black hole as potential homes for human life. A supermassive black hole warps surrounding space-time, according to Einstein’s theory of general relativity, and at least one of the planets in the movie, called Miller’s planet, experienced time passing at a slowed-down rate. For eac ...read more
Do eyelashes exist, in part, to keep our eyes from drying out? (Credit: KDdesignphoto/Shutterstock)
Why do we have eyelashes? The answer might seem simple: those thick hairs on the end of our eyelids simply exist to block intruding particles from landing on our eyeballs.
And in fact, that’s what many scientists have hypothesized. It explains why camels evolved to have long lashes for wandering the dusty desert and why our house pets, in comparison, have stumpy ones.
But it tu ...read more

Carbon dioxide! Little did we realize 100 years ago how this simple gas would become such a cultural lightning rod. Yet, here we are, battling what might be an existential fight that is focused on how much carbon dioxide humans pump into Earth's atmosphere. It isn't a little bit, either. No, humans might be now be the gold standard in carbon dioxide emissions in the history of the planet. ...read more

In recent years, researchers have pinpointed a group of compounds called FODMAPs that are common trigger foods for people with irritable bowel syndrome.
But it wasn’t immediately clear whether eliminating these foods could also help people with more serious conditions like Crohn’s disease or ulcerative colitis — or if it might actually hurt their already-sensitive guts. Now a new report in the journal Gastroenterology suggests a di ...read more

Astronomers believe supermassive black holes probably lurk in the centers of most large galaxies. These gargantuan black holes can gather swirling disks of material around them as their gravity attracts stars and gases. In some cases, these disks can emit vast amounts of light and even s ...read more
