Faulty forms of the brain protein tau trigger tangles inside and outside brain cells of Alzheimer's patients. Scientists say figuring out how to stop bad tau's spread from cell to cell might be key.

Millions of children aren't going to school because of Ebola. The fear is that some kids will never return to class. For others, the time off means putting their career dreams on hold.

The town of Foya has had no new cases in a month. Credit goes to a care center and an ongoing effort to calm fears and allow family members to communicate with patients — and view the dead.

The rate for routine vaccinations of babies used to be 97 percent. Now the figure is 27 percent. Blame it on the rippling effects of the oubreak.

The million-plus healthy residents of Liberia's capital, Monrovia, are doing their best to maintain their lives in a city where Ebola has killed more than 1,300.

There's one place in Monrovia where people continue to gather together despite the threat of Ebola: Sunday church service. One reverend knows firsthand how the smallest mistake can be deadly.

A wearable PET scanner and lasers that could control individual brain circuits are among the projects funded by a $46 million federal effort to accelerate research on the human brain.

If you have a problem with your heart or liver, the diagnosis will likely be made by a lab test or medical image. But neurologist Allan Ropper says those tests often fail when it comes to the brain.

Justin McCowan wanted to help find a cure for Alzheimer's because it's more common in people like him who have Down syndrome. He died in his sleep last week at age 40.

With rising seas, cities like Satellite Beach, Fla., are debating options: defend the shoreline to avoid destruction, or retreat, withdrawing homes and businesses from the water's edge.

By age 40, the brains of people with Down syndrome start to resemble those of Alzheimer's patients. Scientists hope to speed up Alzheimer's drug development by studying people with Down syndrome.

Children learn their most important lessons on the playground, not in the classroom, researchers say.

Since the hormone oxytocin makes people more social, it's easy to imagine it might cause the social deficits of autism. But a study found children with autism no more likely to be short of oxytocin.

Scientists have evidence that beats in the brain — in the form of rhythmic electrical pulses — are involved in everything from memory to motion. And music can help when those rhythms go wrong.
Monday, June 02, 2014
Scientists seem to have answered a fundamental question about the nature of memory. They have found compelling evidence that memories are made by strengthening connections between certain brain cells.

Women with multiple sclerosis often find that they have fewer problems when they are expecting. That led researchers to develop an experimental drug based on a hormone associated with pregnancy.

The research project would place electronic devices in the brain in an attempt to combat post-traumatic stress, depression and other problems that have plagued many veterans of Iraq and Afghanistan.

The National Oceanic and Atmospheric Administration expects a relatively quiet Atlantic hurricane season, with three to six hurricanes developing between June 1 and the end of November. Forecasters say they expect El Nino conditions to develop in the coming months, which should produce winds in the Atlantic that discourage hurricane formation.

Scientists have found that a hormone associated with long life also seems to make people smarter. The gene strengthens the connections between brain cells, a process that's essential for learning.
