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
Our gut hosts an enormous population of bacteria, each species with its own niche (they feed on certain foods), which outnumbers our own cells 100-fold. Most of these bacteria are good bacteria, though. In fact, you couldn’t survive without most of them! They’re among the best decomposers, breaking down dead and organic matter otherwise impossible by the gut alone. But
A Japanese woman in her 70s is the world’s first recipient of cells derived from induced pluripotent stem cells, a technology that promises to work wonders and has the scientific community excited about the perspectives. Surgeons working on the case created the retinal tissue after reverting the patient’s own cells to ‘pluripotent’ state. If you’d like to benefit from stem cells, but
Swiss scientists from the University of Bern demonstrated a new device that essentially generates electrical power from the mechanical energy of heartbeats.
