In our day to day lives, we don’t give much thought to tears – we usually focus more on the emotions that cause them than the salty droplets themselves. Well, tears are much more complex than we give them credit for, as Dutch artist Maurice Mikkers showed. Tears Caused By Emotional Response: There are actually three main type of tears: basal
Though it enjoys to sit or lie down from time to time, the human body is made for moving not sitting. It’s all hardwired in our biology. Inside, there are about 360 joints and about 700 skeletal muscles that enable easy, fluid motion. Our skin is stretchy. The blood circulates best when the body is upright. Basically, every cell in our body itches for a walk. But when you sit down for too long, all sorts of health problems can arise from back and muscle pain, to more threatening long-term problems like hearth disease or cancer. I’ll leave you to Murat Dalkilinç in this extremely enlightening, but also practical TED animated video.
A pair of anthropologists compared the anatomical features o bonobos to those of homo sapiens and other apes to infer any clues that might help us understand how we evolved to look the way we do.
Researchers at MIT have now identified a neural circuit that they believe underpins decision-making in situations such as this, and have started looking into mice’s brains to better understand the biological processes that make us tick and help us pick.
Ever wondered what chins are good for? Upon a quick reflection, you might think it actually has some practical value, supporting your jaw against the massive chewing forces. But that’s nonsense. It doesn’t do any of that, as a recent research concludes. In fact, the chin – the last facial feature to stop growing – actually makes the jaw less resistant to the bending stress of chewing as we age. Though still a mystery, scientists believe the chin is actually a side effect of the rest of the face having become smaller. Much smaller than that of early ancestors or cousin Neanderthals, at least.
Many men (and women) are curious about the average penis size, but Dr. Abraham Morgentaler took it to the next level. He conducted a study on over 15,000 men to create a chart of the average size – and the good news is, you’re probably better off than you think. “Most men tend to believe they’re smaller than average, and there’s
We tend to think that sexual activity slows down and ultimately stops as we end, but a new study has shown that it’s not as bad as we think. Over half of all men and almost a third of all women over 70 are still sexually active – with over a third of all people having sex at least twice a month.
We like big butts and I know why: because it helps babies develop their brains properly. Researchers have found that especially during breastfeeding, the development of babies’ brains relies on fat supplies stripped directly from the mother’s thighs and bottom.
I don’t think anybody has ever claimed that running is a 100% wonderful experience. Even the most avid runners still have to get past the painful parts of that morning jogging session. However, there’s a common misconception that some people just aren’t made to run. With the exception of those with certain chronic medical problems, of course, most human bodies
In 2003, Dr. Lihong V. Wang at Washington University introduced one of the most exciting technologies we’ve had the chance to see in a long while. By combining ultrasound and light absorption, Wang and colleagues developed a new method that makes multicontrast images of biological tissues several inches below the skin. Among others, this allows specialists to see cancer in action with unprecedented
