How a memory game could help us understand brain injury

After a traumatic brain injury, why do some people regain skills quickly while others face long-lasting setbacks? Boston University neuroscientist Jerry Chen of BU’s Center for Systems Neuroscience and colleagues have been trying to answer this question by understanding which parts of the brain process sensory information and which remember different skills. The latest research...

Scientists discover way to stop spread of devastating childhood cancer

Researchers at the University of East Anglia and the University of Manchester have made an important breakthrough that could lead to ‘kinder’ treatments for children with bone cancer, and save lives. Current treatment is grueling, with outdated chemotherapy cocktails and limb amputation. But despite all of this, the five-year survival rate is poor at just...
