We all know that if we want what we've studied during the day to stick, it's best to get a good night's sleep. And while scientists have long understood that our memories rely on connections being built between neurons in our brains, it's not been clear how sleep actually helps to consolidate that information.
Now, two new studies have found biological evidence that expains the age-old wisdom that if we want to remember, we need to sleep to forget.
While other noble gas elements have shown signs of forming compounds under extreme pressure, helium has remained firmly exclusive - until now. Scientists report creating what appears to be a stable helium-sodium compound, and it challenges some of the most basic assumptions of modern chemistry.
Bill Nye: Evolution is the fundamental idea in all of life science. So if we raise a generation of science students who don’t understand the main idea in biology they’re going to be incompletely educated students and this is going to be trouble for the United States because the United States keeps in the game economically by innovating – having new ideas, new products, new ways of doing things. That’s what the United States produces and brings to the world. And if we raise a significant fraction of our students who don’t understand...
Since 1995, hundreds of poor children in Muzaffarpur, India have mysteriously suffered seizures and feelings of brain fogginess, usually in the morning. Many would soon die. This happened every year between May and July: In 2014, for example, Muzaffarpur hospitals admitted 390 kids with the symptoms, resulting in 122 deaths.
ForAllSecure, the minds behind the Mayhem Hacker Robot who won the Pentagon's Cyber Grand Challenger Contest, are working to make the software a bug fixer. They are aiming an autonomous system which would find vulnerabilities in the commercial devices like routers and automatically fix them.
