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.

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.

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.

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.
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.
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.

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 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.
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.

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.
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.

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.

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.
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.
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.
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.
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.
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.
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.

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.
