Astronomers have detected an ancient stellar remnant that’s 10 times fainter than the dimmest white dwarf ever discovered. Fortuitously orbited by a pulsar, this cold and collapsed star consists of crystallized carbon — essentially making it an Earth-sized diamond in space. Indeed, this white dwarf would have never been discovered if it hadn’t been for the pulsar that spins around it.
Be prepared for a whole hell of a lot of scrolling. This map is pretty awesome in the sense that it really puts perspective on just how much distance there is between us and basically everything in just our small corner of the Milky Way.
Genetic research has already discovered that early humans in Europe mingled genes (bumped uglies) with Neanderthals, now it looks like Tibetans’ unique tolerance for extremely high altitudes can directly be traced to genes from another long extinct hominid race, the Denisovans. Denisovans were one of many ancient human species that lived at the same time as early Homo sapiens. The genes that Tibetans inherited allow for a better use of blood oxygen at higher altitudes that would make lesser mortals’ blood thicken above 15,000 feet to deadly levels.
The simple principle that illustrates how we may have been misinterpreting quantum mechanics this whole time
At the quantum level, things have been described as “super weird” and “doesn’t make any damn sense based on what we know”, what with quantum particles appearing and disappearing, moving across time and space instantaneously, spontaneously come into being and annihilate, seeming to exist in multiple places at once, etc etc. But one interesting experiment has shown that perhaps the quantum world does operate with some kind of mechanics we already understand, even by certain principles of classical physics.
The experiments involve an oil droplet that bounces along the surface of a liquid. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet’s interaction with its own ripples, which form what’s known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles — including behaviors seen as evidence that these particles are spread through space like waves, without any specific location, until they are measured.
Diabetes is a disease that affects more and more people every year, especially in the US, because fat unhealthy Americans or whatever you’re about to say. While diabetes isn’t the death sentence that it used to be, it still can drastically reduce one’s life span as well as just being an enormous pain in the ass. As a more permanent solution to insulin or injections, scientists have now developed a bionic pancreas— basically it’s an insulin pump embedded in your body that uses sensors to check blood glucose levels every five minutes and doles out the amount of insulin needed.
