Estimates from the Alzheimer's Association show that more than 5 million Americans are living with Alzheimer's disease. Those numbers don't include the millions whose brains show signs of the disease but whose symptoms aren't obvious yet.
Despite evidence to the contrary, many Americans believe cellphones cause cancer and that health officials are covering it up. Discredited theories about vaccines and fluoridation also remain popular.
An analysis of DNA from ancient and modern chicken bones from the Pacific islands shows they are genetically distinct from South American birds.
Two mapmakers made the place up. It wasn't real. Then, oddly, it popped into being. I am not making this up. It happened. Then it un-happened.
Giant lizards are coming out of hibernation in Florida. Trouble is, Robin Sussingham of WUSF reports, they're members of an invasive species with a taste for the eggs and hatchlings of native animals.
Drs. Deirdre Barrett and Robert Stickgold discuss the case of Dion McGregor, a sleep talker whose vivid and expansive somniloquies are the subject of the album, Dreaming Like Mad with Dion McGregor.
Dark chocolate may help the heart and waistline. Now scientists have figured out one reason why: Bacteria in the gut turn cocoa into compounds that lower inflammation and make us feel full.
Andrei Linde, one of the founding fathers of cosmological inflation, answers the door to the news that his theory appears to have been confirmed.
Physicists say they've discovered a faint signal from just moments after the universe began. If confirmed, it could revolutionize our understanding of the cosmos. But not everyone is convinced.
In the 1980s, NASA engineer Robert Farquhar came up with a sly plan to divert the ISEE-3 satellite from its original path to visit a comet instead. Now Farquhar has another big plan for his "baby."
At issue in Iran nuclear talks is a heavy water reactor the country is building. Iran says it wants the reactor for medical research, but the West is worried that such reactors can produce plutonium.
Paris is suffering from the worst smog it's seen in decades. Associated Press Paris Bureau Chief Angela Charltan explains the ways the city's dealing with the smog, including restrictions on drivers.
Physicists using data from an Antarctica telescope say they've observed evidence of primordial gravity waves — in other words, echoes of the Big Bang. If real, this may be a big advance for physics.
Chemicals in cigarette smoke can settle on clothes, furniture and walls. Researchers call this thirdhand smoke and say laboratory experiments suggest it could be hazardous.
Programs — some already on your smartphone — are preparing useful information based on your past behavior, ushering in the era of predictive, or anticipatory, computing.
Roughly one in five unvaccinated people had the flu between 2006 and 2011, but only a quarter of them had symptoms, a study found. That could affect how the virus spreads.
Researchers say they have found indirect evidence that gravitational waves rippled through the fabric of space time in the first sliver of a second after the Big Bang.
How reliably can we find the fakes? A new study says the more forgeries people come across, the better they are at spotting them. But there are multiple traps that can cloud screeners' judgment.
With tablet technology still relatively new, pediatricians are trying to understand how interactive media affects children.
A group of physicists banned PowerPoint from forums, and they're aren't the only people who say we should cut back on slide-based presentations: Others include Amazon, LinkedIn and NASA.
