Making Bones from Beer Waste

August 28, 2014 8:30 am | by Skip Derra | Articles | Comments

At first blush it is a bit disingenuous, using beer waste as a base material for new bone. But that is exactly what a multidisciplinary team of researchers in Spain has come up with in a process for making the substrate material on which bone can be regenerated.

Scientists Plug Into a Learning Brain

August 28, 2014 8:30 am | News | Comments

Learning is easier when it only requires nerve cells to rearrange existing patterns of activity than when the nerve cells have to generate new patterns, a study of monkeys has found.                   

Technology May ID Strains in Body Tissues Before Injuries Occur

August 27, 2014 1:05 pm | Videos | Comments

Researchers have developed algorithms to identify weak spots in tendons, muscles and bones prone to tearing or breaking. The technology one day may help pinpoint minor strains and tiny injuries in the body’s tissues long before bigger problems occur.
