Synthetic Stingray May Lead To A Better Artificial Heart

Thursday, July 07, 2016

Using gold, silicone and heart cells from a rat, scientists have made a tiny artificial stingray. The engineering involved in propelling it could help make a heart that's more than a mechanical pump.


A Protein That Moves From Muscle To Brain May Tie Exercise To Memory

Thursday, June 23, 2016

In mice, monkeys and people, exercise releases a protein called cathepsin B. And as blood and brain levels of this protein rise, memory gets better. But the protein has a dark side, too.


How A Team Of Elite Doctors Changed The Military's Stance On Brain Trauma

Friday, June 10, 2016

An Army Buddy's Call For Help Sends A Scientist On A Brain Injury Quest

Wednesday, June 08, 2016

Harvard researcher Kit Parker built his academic career studying the heart. But Parker, also an officer in the U.S. Army Reserve, switched his focus to figuring out how IED blasts damage the brain.


A Concussion Can Lead To Sleep Problems That Last For Years

Eighteen months after a concussion or other traumatic brain injury, two-thirds of the patients in a recent study were still sleepy during the day. And most were unaware of their symptoms.


Half Your Brain Stands Guard When Sleeping In A New Place

Thursday, April 21, 2016

No wonder we don't feel rested after a first night in a new place: Half of our brain has stayed alert while the other half enjoyed deeper sleep, a study finds. We really have been half-asleep.


Technology Helps A Paralyzed Man Transform Thought Into Movement

Wednesday, April 13, 2016

An implant and wires that reroute nerve signals from a man's brain to his hand allow him to grasp and lift objects, after much practice. But easy, wireless signaling from the brain is still the goal.


Big Financial Costs Are Part Of Alzheimer's Toll On Families
