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.

A district judge in Texas has dismissed the last remaining criminal charges against two activists who covertly recorded videos of themselves attempting to buy fetal tissue from Planned Parenthood.

David Daleiden and Sandra Merritt used fake IDs when they approached the organization. They were indicted for tampering with government records, a felony charge. Those charges have now been dismissed on technical grounds.

An attorney for the pair called it "a huge win for First Amendment rights," NPR's Jennifer Ludden reports.

The prime minister of Australia said he is "shocked and appalled" after seeing footage of children being hooded, shackled, stripped and held on the floor by prison guards at a youth detention facility in the Northern Territory.

Charles Kinsey, a Florida health worker, was swept into the national debate about police and African-Americans after video of police shooting him went viral.

If Hillary Clinton wins the White House in November, she would be the first female president of the United States.

There would be a few other firsts in the family that night as well: Bill Clinton would be the first man married to a U.S. president. He would also become the first former president to become the first spouse.

Tuesday night, Bill Clinton addresses the Democratic National Convention in Philadelphia to make the case for his wife. It will be his 10th time addressing the DNC.

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.

Two men attacked a church near Rouen, France, on Tuesday, taking several hostages and killing a priest in his mid-80s before the attackers were shot to death by police.

The self-described Islamic State, through the group's Amaq news agency, claimed responsibility for the attack in the small town of Saint-Étienne-du-Rouvray.

Two car bombs in Mogadishu, Somalia, killed 13 people on Tuesday, in an attack that has been claimed by the Islamist militant group al-Shabab, The Associated Press reports.

The twin suicide bombings occurred near the African Union peacekeeping base, by the Mogadishu airport.

One explosion targeted the offices of a U.N. mine-clearing agency, the AP writes:

'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.

A reported abduction in Brazil is sending shock waves through the sporting world, as the mother-in law of Bernie Ecclestone, the billionaire who runs the Formula One Group, is apparently being held for ransom.

From Rio de Janeiro, NPR's Lulu Garcia-Navarro reports for our Newscast unit:

"Bernie Ecclestone is the head of the Formula One car racing franchise and one of the richest men in Britain. His wife is Brazilian, and her mother was apparently grabbed by criminals in Sao Paulo, who are asking for a $37 million ransom from the billionaire.

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.
