Five billion people worldwide have two non functional versions of the gen, a c t n three. This non functional gen is more common in colder climates like central and northern europe than in africa. To find out why, researches recruited a group of volunteers with and without the function gean to immerse these participants in cold water. The scientists found that more of the volunteers with the non functioning gen could maintain a higher body temperature than those with the functional variant.
The surprising structure of protons, and a method for growing small intestines for transplantation.

00:45 Probing the proton’s interior
Although studied for decades, the internal structure of the proton is still throwing up surprises for physicists. This week, a team of researchers report an unexpected imbalance in the antimatter particles that make up the proton.
Short Bowel Syndrome is an often fatal condition that results from the removal of the small intestine. Treatment options are limited to transplantation, but donor intestines are hard to come by and can be rejected by the body. Now researchers may have developed a method to grow a replacement small intestine using stem cells and a small section of colon.
