Brain Implant Restores Sense Of Touch To Paralyzed Man

Thursday, October 13, 2016

A mind-controlled robotic arm has pressure sensors in each fingertip that send signals directly to a paralyzed man's brain. It's still experimental, but could eventually help thousands, engineers say.


Brain Game Claims Fail A Big Scientific Test

Monday, October 03, 2016

When a team of researchers evaluated the scientific literature on brain games, they found little evidence that the products improve memory or thinking in real-world tasks.


Rats That Reminisce May Lead To Better Tests For Alzheimer's Drugs

Thursday, September 29, 2016

Most potential Alzheimer's drugs are tested on mice. But rats may be a better choice because they seem to have a type of memory that's more like ours, and also are highly vulnerable to Alzheimer's.


War Studies Suggest A Concussion Leaves The Brain Vulnerable To PTSD

Monday, September 26, 2016

Troops returning from Iraq and Afghanistan are far more likely to develop post-traumatic stress disorder if they have suffered a concussion. The reason may be a change in the brain's fear circuits.


How A 'Sixth Sense' Helps Simone Biles Fly, And The Rest Of Us Walk

Wednesday, September 21, 2016

Scientists are finally beginning to understand proprioception, a sense that tells us where our body is in space. Much of what they've learned comes from two girls with a rare genetic disorder.


When Blind People Do Algebra, The Brain's Visual Areas Light Up

Monday, September 19, 2016

A study of 17 people who have been blind since birth found that areas of the brain usually devoted to visual information become active when a blind person is solving math problems.


Test Of Experimental Alzheimer's Drug Finds Progress Against Brain Plaques

Wednesday, August 31, 2016

Researchers have failed repeatedly in their efforts to slow or halt Alzheimer's disease. But there are hints that an experimental drug can do what previous medicines could not.


Surfers And Scientists Team Up To Create The 'Perfect Wave'

Tuesday, August 30, 2016

Surfers once deemed man-made waves weak and mushy compared to the best that break along the coast. Then engineers and an 11-time world champion surfer showed just how good an artificial wave can be.


Despite Lessons From 2009 Quake, Buildings In Italy Remain Vulnerable

Wednesday, August 24, 2016

Earthquakes are common in central Italy. After the 2009 quake in L'Aquila, there were stricter building codes and recommendations for new construction. But many older buildings remain vulnerable.


Olympic Athletes Still Use Some Rx Drugs As A Path To 'Legal Doping'

Wednesday, August 10, 2016

Hundreds of elite endurance athletes were taking the prescription heart drug meldonium until it was banned in January. But a similar heart drug, telmisartan, is still allowed.


A Soldier-Scientist's Insights Expand Understanding Of Brain Injuries

Monday, August 01, 2016

Harvard researcher Kit Parker put his academic career on hold to serve in the Army in Afghanistan. When he returned from war, he made a discovery that changed our understanding of brain injuries.


A Sniff Test For Alzheimer's Checks For The Ability To Identify Odors

Tuesday, July 26, 2016

New research suggests it may be possible to spot people in the early stages of Alzheimer's by testing their ability to recognize fragrances. The goal is a quick and inexpensive screening test.


A Mouse Watches Film Noir And Offers Clues To Human Consciousness

Wednesday, July 13, 2016

Researchers in Seattle have created a public observatory for studying the visual circuitry in a mouse's brain. Among the attractions: watching 18,000 neurons respond to Orson Welles' Touch of Evil.


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

A group of specialists called the Gray Team challenged the dogma that said head injuries were serious only if they were obvious and bloody. Bomb blasts can lead to lasting but invisible damage.


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

Wednesday, April 27, 2016

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.
