Scientists have long sought a way to detect Alzheimer's before symptoms appear.
An experimental blood test can identify people in their 70s who are likely to develop Alzheimer's disease in the next two or three years. The test is accurate more than 90 percent of the time, scientists reported Sunday in Nature Medicine.
Kentucky Sen. Rand Paul's straw poll victory at last week's Conservative Political Action Conference wasn't unexpected for the presidential contender. In third place, however, was a surprise finisher.
Dr. Ben Carson is one of a handful of black Republicans that conservatives are buzzing about this year. While the GOP has made strides in cultivating viable black candidates, the party still has difficulty resonating with black voters.
He may not have the rock-star status of top conservatives like Paul or Sen. Ted Cruz of Texas, but Carson's following is growing.
On-air challenge: For each five-letter word provided, insert two letters after the first letter to complete a familiar seven-letter word.
Last week's challenge: The challenge came from listener Harry Hillson of Avon-by-the-Sea, N.J. Take the first name of a nominee for Best Actor or Best Actress at last Sunday's Oscars. You can rearrange these letters into a two-word phrase that describes his or her character in the film for which he or she is nominated. Who is this star, and what is the phrase?
After the Rockefeller Center mural was destroyed in 1934, Diego Rivera recreated this version, named Man, Controller of the Universe, which is on display at the Palacio de Bellas Artes in Mexico City. The story of the original mural's creation and destruction is the focus of a Mexican Cultural Institute exhibition in Washington, D.C.

An early sketch of the mural shows how it differed from what Diego Rivera painted in Rockefeller Center.
When Mexican artist Diego Rivera was commissioned in 1932 to do a mural in the middle of Manhattan's Rockefeller Center, some might have wondered whether industrialist tycoon John D. Rockefeller Jr. knew what he was getting into.
In 1934, the legendary artist's work was chiseled off the wall.
Now, in Washington, D.C., the Mexican Cultural Institute has mounted a show that tells what happened to Rivera's mural.
