Two studies released at an international Alzheimer's meeting Tuesday suggest doctors may eventually be able to screen people for this form of dementia by testing the ability to identify familiar odors, like smoke, coffee and raspberry.

In both studies, people who were in their 60s and older took a standard odor detection test. And in both cases, those who did poorly on the test were more likely to already have — or go on to develop — problems with memory and thinking.

It used to be one of the worst places in the world when it came to protecting children.

A 2007 Violence Against Children Survey coordinated by UNICEF and the Center for Disease Control and Prevention found one in three girls in Swaziland was sexually abused before age 18. (The global rate is 1 in 5, according to the World Health Organization.)

The Federal Bureau of Investigation says it is looking into the hacking of the Democratic National Committee computer system, after the website WikiLeaks published thousands of internal emails on the eve of the party's convention.

How WikiLeaks obtained the emails is unclear.

'Clone Sisters' Of Dolly The Sheep Are Alive And Kicking

Jul 26, 2016

About four years ago, Kevin Sinclair inherited an army of clones. Very fluffy clones.

"Daisy, Debbie, Denise and Diana," says Sinclair, a developmental biologist at the University of Nottingham in England.

The sheep are just four of 13 clones Sinclair shepherds, but they're the most famous because of their relation to Dolly, the sheep that made headlines two decades ago as the first successfully cloned mammal.

The trip had mechanical setbacks, and the plane's average speed would be legal on many American streets. But when the Solar Impulse aircraft touched down in Abu Dhabi in the early morning darkness Tuesday, it successfully completed a round-the-world voyage using only solar power.

Swiss pilots Bertrand Piccard and André Borschberg took turns flying the single-seat aircraft that began its trip on March 9 of 2015, flying more than 26,700 miles in a total of 17 stages (23 days) as they soared under the sun's power and then glided through the night.

Now a story about a tiny island nation trying, literally, to put itself on the map. The Faroe Islands sit halfway between Iceland and Norway. About 50,000 people live there on an archipelago so remote it's not even included on some world maps.

The auto industry is watching to see whether Tesla, which has its roots in the tech world of Silicon Valley, can pull off its goal of mass producing cars.

The goal hit a road bump in May when Tesla had its first fatality in a vehicle using Autopilot, a feature it offers that allows the car to do a lot of the driving.

It's supposed to be an assist. Before you engage it, it warns you not to take your hands off the wheel.

Several times a month, Jessica Wen, a pediatrician specializing in liver diseases, has a teenager show up at her clinic at the Children's Hospital of Philadelphia with an unexpected diagnosis: hepatitis C.

Hepatitis C virus, or HCV, is the most common bloodborne infection in the U.S. and a leading cause of liver failure and cancer. Injection drug use is a common risk factor, as is receiving a blood transfusion before 1992. But some of the teens Wen sees picked up the illness another way: at birth, from their mothers.

The water supply for communities in the Canadian province of Saskatchewan is threatened by an oil spill that dumped an estimated 66,000 gallons of heavy oil, along with natural gas used to dilute it, into a major river.

The pipeline that broke is owned by Husky Energy Inc. The site of last Thursday's leak is within 1,000 feet of the North Saskatchewan River.

Verizon is buying Yahoo for $4.8 billion, acquiring its "core Internet assets" — search, email, finance, news, sports, Tumblr, Flickr — in essence writing the final chapter of one of the longest-running Internet companies.

A 12-year-old boy named Strazh hangs from the monkey bars, staring at the ground. The other kids in the park in San Francisco aren't interested in him. And he's not interested in them.

"I just like to play by myself," he says.

Strazh has autism. Today is a good day. But on most others, Strazh has meltdowns. Something frustrates him and he can't control his emotions.

"I sometimes end up screaming," he says. "And I end up yelling and screaming."

Hair products aren't at the top of most people's health worry list, but the Food and Drug Administration is investigating a surprisingly high number of reports of problems after people used a particular cleansing conditioner.

As of July 7, the FDA had received 127 complaints of "hair loss, hair breakage, balding, itching, and rash" after people used WEN by Chaz Dean cleansing conditioner products — more reports than the agency has ever received for a cosmetic hair product.
