Researchers who developed a collection of human stem cells with glowing internal structures have begun sharing them with colleagues. The glow reveals the secret workings of cells.

Our canine pals remember lots of facts, like where to find the food bowl. Now there's evidence they also have aspects of "episodic memory," which allow them to relive experiences and events.

Bombarding young mice with video and audio stimulation changes the way the brain develops. But some scientists think those sorts of brain changes could protect kids from stressing out in a busy world.

Each lab-grown cluster of human cells fits on a pin's head, but contains some of the cell types and circuitry of a real brain. The structures already are offering insights into how Zika attacks.

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.

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.

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.

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.

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.

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.

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.

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.
