Researchers discover how key enzyme repairs sun-damaged DNA

Researchers have long known that humans lack a key enzyme -- one possessed by most of the animal kingdom and even plants -- that reverses severe sun damage. For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA. The discovery holds promise for future sunburn remedies and skin cancer prevention.
The Korea Advanced Institute of Science and Technology team led by bio molecular engineering professor Lee Sang-yup have developed a technology to artificially create spider dragline silk proteins that can be used to make ultra-strong synthetic fibres and bulletproof vests.
Shade-grown coffee farms support native bees that help maintain the health of some of the world's most biodiverse tropical regions, according to a study by a University of Michigan biologist and a colleague at the University of California, Berkeley.

Overturning more than 40 years of accepted practice, new research proves that the tools used to check tests of "general mental ability" for bias are themselves flawed. This key finding challenges reliance on such exams to make objective decisions for employment or academic admissions even in the face of well-documented gaps between mean scores of white and minority populations.
Hockey fans likely would assume that body-checking -- intentionally slamming an opponent against the boards -- causes the most injuries in youth ice hockey. But they would be wrong.
One molecule, many more insulin-producing cells to treat diabetes, says Pitt team
Posted by eurekalert 1 day 21 hours ago (http://www.eurekalert.org)
With a single stimulatory molecule, human insulin-producing beta cell replication can be sustained for at least four weeks in a mouse model of diabetes, according to researchers at the University of Pittsburgh School of Medicine in Diabetes. They also found several cocktails of molecules that drive human beta cells to replicate, as well as important differences between mouse and human beta cells
