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.
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.
While most mammals have long become comfortable to land, a neat thing happens when your body or that of any mammal is submerged in water— instantly, your heart rate slows, blood begins to flow away from the limbs into the torso to combat the external pressure and oxygen is used more efficiently. Even just dipping your face in water for a few seconds will trigger this lowered heart rate. This entire combination of reactions can not only help to lower stress, but it makes it possible to dive to depths that otherwise might crush your lungs like tinfoil.
Fruit bats are one of the few species to this point other than humans that have been observed (giggity) having oral sex for pleasure, as opposed to just licking genitals for hygiene. But now you can add brown bears to that list, because researchers have now observed brown bear dick sucking 28 times among bears in a sanctuary in Croatia.
For centuries, some people have touted the benefits of periodic fasting, and now with 21st century science, researchers have discovered that fasting for three days apparently “restarts” the immune system by triggering the body to turn stem cells into a batch of brand new white blood cells. Scientists at the University of Southern California say the discovery could be particularly beneficial for people suffering from damaged immune systems, such as cancer patients on chemotherapy.
For a long time, it’s mainly been thought that the big difference in facial structure between men and women was a product of ancient aesthetic selection and due to the introduction to tougher to eat foods. But a new study theorizes that men’s larger brows, cheeks and jaws evolved through combat with other men. This theory seems to be controversial, though I’m not exactly sure why— it’s not like most males through mammals, birds, reptiles and even dinosaurs evolved some sort of physical adaptation to be able to deal with brawls amongst males of their same species. Obviously, we’ve also had pointy tools for a long, long time that do pretty well at cutting a bitch up instead of fists, which is why we haven’t evolved super jaws, but certainly one could imagine that among very early humans, men with fragile little girly jaws that couldn’t take a simple punch probably weren’t getting a whole lot of cavewoman pussy.
Even though math and art are sometimes seen as being opposites, both activate the same part of the brain that appreciates beauty. So whether it’s the Mona Lisa or seeing someone compute the movement of subatomic particles, they both are interpreted by your brain as “damn that’s pretty”. And it is.
