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
Seems like your mom was right all along: scratching does, in fact, makes the itching worse. This was the conclusion reached by a group of researchers at Washington University School of Medicine in St. Louis after the scientists studied the molecular and neural pathways that cause and relieve itching. The findings suggest that scratching releases serotonin – a key neurotransmitter involved in
An interdisciplinary team of researchers has created a paint-on, see-through, “smart” bandage that glows to indicate a wound’s tissue oxygenation concentration. Oxygenation plays a crucial role in healing, so mapping it in severe wounds and burns can help to significantly improve the success of surgeries to restore limbs and physical functions. “Information about tissue oxygenation is clinically relevant but is often
A field researcher from America has transplanted fecal microbiome from a Tanzanian tribesman to his own gut. Why? Well… to see what happens, basically. “AS THE SUN set over Lake Eyasi in Tanzania, nearly thirty minutes had passed since I had inserted a turkey baster into my bum and injected the feces of a Hadza man – a member of one of
The heart regularly speeds up or down its beating frequency to adjust to the body’s needs. Even in stable conditions (when you’re not particularly active or your active for a constant time), the amount of time between heart beats is variable. A team of doctors and engineers at Caltech’s Division of Engineering and Applied Science have now found a better way to assess
