Scientists say they have found a way to restore hair colour with a drug. Prof. Karin Schallreuter and her team came across their treatment after discovering the cause of greying – a wear-and-tear process known as oxidative stress. As we age, our hair accumulates hydrogen peroxide, a bleach that robs it of its natural colour. The therapy removes this bleach, the FASEB journal reports. It is not yet clear if it can help avoid going grey, reports BBC News.

Sunlight could help to lower blood pressure

Researchers at the University of Edinburgh found that exposure to ultraviolet light lowered the blood pressure of volunteers.

The other half either implicitly considered costs or didn't address them at all, reports Reuters.

Gene test may help guide prostate-cancer treatment

A new genetic test to gauge the aggressiveness of prostate cancer may help tens of thousands of men each year decide whether they need to treat their cancer right away or can safely monitor it. The new test, which goes on sale Wednesday in the United States, joins another one that recently came on the market. Both analyze multiple genes in a biopsy sample and give a score for aggressiveness, similar to tests used now for certain breast and colon cancers, reports Fox News.
