If you’ve ever gone for a run you probably know the feeling of exhaustion that comes with trying to catch your breath. Maybe your nostrils burn and your heart races as your lungs beg for air, but none of these body parts is responsible for controlling your breathing. In fact, it’s your brain that’s telling your body to breathe all the time, even though you may only notice when your breathing becomes heavy after exercising. Continue reading Why don’t I have to think about breathing?
Our medical system is at a crisis point. Bacteria that we could once easily dispatch are out-evolving our current antibiotics, leading to the growth of “superbugs.”
When historians trace back the roots of today’s opioid epidemic, they often find themselves returning to the wave of addiction that swept the U.S. in the late 19th century. That was when physicians first got their hands on morphine: a truly effective treatment for pain, delivered first by tablet and then by the newly invented hypodermic syringe. With no criminal regulations on morphine, opium or heroin, many of these drugs became the “secret ingredient” in readily available, dubiously effective medicines. Continue reading How Advertising Shaped the First Opioid Epidemic
In 2015, two doctors at New York City’s Mount Sinai-Beth Israel Medical Center were examining a patient’s bile duct when they noticed something curious: a network of fluid-filled cavities within the tissue layer that was not consistent with any previously described anatomy. Further research revealed that these cavities can be found throughout the human body and, as Rachael Rettner of Live Science reports, scientists at New York University’s School of Medicine believe the anatomical discovery should be classified as a new organ.
This month in Pyeongchang, elite teams of physics and materials science experts from all over the world will dazzle us with ostentatious displays of grace and power. We commonly refer to these experts as athletes. Gymnasts demonstrate their subtle understanding of gravity and momentum. Swimmers and divers master fluid dynamics and surface tension. Skiers harness their knowledge of friction and hydrology, and lugers push their aerodynamics chops to the limits. Olympians, after all, understand science at a visceral level in ways most of us don’t.
The mind-body connection has become a buzzword in recent years, and now, new research in monkeys highlights how the link may actually work.
