Viewpoint: Protecting NFL players' brains demands 'unbiased researchers with good intentions'
As a spectator, it’s easy to forget the long term consequences of 300 pound humans crashing into each other at over 20 miles per hour. But this is the reality of American football. During play, the brain is one of the most susceptible parts of the body and the long-term danger may remain hidden until years after retirement. New safety rules and improved helmets prevent injuries such as skull fractures.
Helmets protect athletes’ skulls. Will the NFL use neuroscience to protect their brains?

Despite the acknowledged importance, the neural correlates of compulsive drinking are not well understood.
A failed Alzheimer's drug stops cancer cells from shedding their coats and hiding from the immune system
www.ccPixs.com A chance reading and a fortuitous overlap between Alzheimer's and multiple myeloma biology gave a failed drug new life December 19, 2019 In the pharmaceutical industry, failure may be just the beginning. Imagine spending over 10 years and millions of dollars only to have a promising drug candidate fail a Phase III clinical trial. That’s what happened to the drug companies Eli Lilly in 2010 and Bristol-Myers Squibb in 2012.
Drug resistance: Can targeting evolution be the solution?
by Christina Marvin | Science has given doctors more and more powerful drugs to deploy against infectious diseases and cancers in recent decades, and yet many new therapies have failed to live up to their promise. Andrew Read has some ideas about how to change that. As an evolutionary biologist, Read views much drug therapy as an impossible game of "whack-a-mole," where microorganisms and cancer cells evolve and change to resist drugs and survive.
