The sudden onset of kidney problems often serves as a red flag for doctors to discontinue their patients' use of so-called proton pump inhibitors (PPIs), which are sold under the brand names Prevacid, Prilosec, Nexium and Protonix, among others.
Black holes are among the most fascinating objects in the known Universe. But despite the fact that they're suspected to lurk at the centre of most galaxies, the reality is that no one has ever been able to actually photograph one.
That's because black holes, as their name implies, are very, very dark. They're so massive that they irreversibly consume everything that crosses their event horizon, including light, making them impossible to photograph....
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...
