Most of the front door of Rachel Taylor's little yellow house in White Sulphur Springs, W. Va., is pasted with paw prints where her dog struggled to get inside during the flood last month. He was too big to carry through the rising waters.

Across the street, nestled between two battered houses, an empty lot is marked by a cross with an array of flowers and photos — a small memorial for a family washed away by the torrent.

The first time he encountered a tiger shark in the water, marine ecologist Neil Hammerschlag was in the Bahamas conducting research. His team was on a boat and hadn't seen many sharks, so when someone yelled, "Tiger shark!" he grabbed his snorkel gear and camera and jumped into the water.

"One [tiger shark] moved right in toward me and came close," Hammerschlag tells Fresh Air's Dave Davies. "It opened its mouth, and I was looking through its mouth down its gut and seeing its gills from the inside."

For parents concerned that their preschoolers may one day gain excess weight, a study published Thursday suggests one strategy for keeping the little ones on track that isn't related to food: Tuck them in earlier.

Scientists reporting online in The Journal of Pediatrics found, in a study of not quite a thousand U.S. children, that preschoolers who got to bed by 8 p.m. were about half as likely as those who turned in after 9 p.m. to develop obesity in their teenage years.

Viral hepatitis is a sneaky killer, accounting for nearly 1.5 million deaths in 2013 — equal to or greater than the number of yearly deaths caused by malaria, tuberculosis or HIV/AIDS.

People share passwords all the time. A husband might give his wife his bank account login so she can pay a bill. A professor might ask a secretary to check emails. Comedian Samantha Bee's segment on Syrian refugees featured her teaching them essential phrases in U.S. culture, including "Can I have your HBO Go login?"

After more than a week of violence and racial tension sparked by the deaths of black men at the hands of police and the shooting deaths of five officers in Dallas, we're getting more perspective from African-American law enforcement officials.

There are a lot of people suffering from a mental health condition who need therapy. And there are a lot of therapists who want to help them. But both sides believe the insurance companies that are supposed to bring them together are actually keeping them apart.

Insurance companies, for their part, say there's a shortage of therapists.

But it's not that simple. Especially in urban areas, there are lots of therapists. They just don't want to work with the insurance companies.

When we meet the heroin dealer called Bone, he has just shot up. He has a lot to say anyway. He tells us about his career--it pretty much tracks the evolution of drug use in America these past ten years or so. He tells us about his rough past. And he tells us about how he died a week ago. He overdosed on his own supply and his friend took his body to the emergency room, then left.

Many public figures who took to Twitter and Facebook following the murder of five police officers in Dallas have faced public blowback and, in some cases, found their employers less than forgiving about inflammatory and sometimes hateful online comments.

Letting mice watch Orson Welles movies may help scientists explain human consciousness.

At least that's one premise of the Allen Brain Observatory, which launched Wednesday and lets anyone with an Internet connection study a mouse brain as it responds to visual information.

The Senate on Wednesday overwhelmingly approved a bill intended to change the way police and health care workers treat people struggling with opioid addictions.
