Reporting in Science, researchers write that a red disk painted in Spain's El Castillo cave is at least 40,800 years old--making it the oldest known European cave art. Archaeologist Alistair Pike discusses how his team dated the disk, and whether Neanderthals could have painted it.
This is SCIENCE FRIDAY; I'm Ira Flatow. Imagine a cargo plane dropping you off in a remote corner of the African jungle. The area you've just entered is under quarantine for a mysterious plague. Nobody knows how many people it has killed, but all who have fallen sick die within eight days, first high fever, headache, hallucinations, then usually bleeding to death.
Mitt Romney referred to morning after-pills as 'abortive pills.' The FDA-approved label on Plan B indicates it may prevent fertilized eggs from implanting in a woman's uterus. Dr. Kristina Gemzell-Danielsson, an obstetrics and gynecology professor at Karolinska Institute, discusses the growing scientific evidence to the contrary.
There are trillions of germs that live on us. What are they? What do they do? Inquiring minds want to know, and so they set to find out.

Dr. John knows New Orleans like no one else. The gritty, growly music legend boasts a lengthy career, during which he's perfected a blend of New Orleans voodoo blues, funk and rock 'n' roll. Locked Down, his latest album — produced by The Black Keys' Dan Auerbach — was released earlier this year.
We were very tempted earlier this week to post about the guy who said he's writing a memoir called Kindness in America and had gotten shot while hitchhiking across the country. Many sites picked up that oh-so-ironic story.
President Richard Nixon tells reporters he will not allow his legal counsel, John Dean, to testify before Congress in the Watergate investigation, March 15, 1973. Leaks about the Watergate break-in eventually helped lead to Nixon's resignation. And his administration fought and lost a Supreme Court battle over leaking of the so-called Pentagon Papers about Vietnam.
A leak — in a pipeline, at a nuclear plant, within a top-secret agency — can be dangerous, disastrous, deadly. But sometimes a leak can also be a good thing — drawing attention to a larger systemic problem.
The debate over news leaks bubbled up again this week after reports that The New York Times relied on information from top-tier and unnamed U.S. officials to reveal details about the U.S. cyberbattle against Iran.
Katerina Margaritou and Elias Tilligadas live in Athens. They're getting married next Wednesday — three days after the Greek election that has the global economy on edge.
Katerina is a chemist, and she works for a company whose main customer is the Greek government. The Greek government, of course, is broke. So Katerina hasn't been paid since last year.
"I'm very happy because I'm getting married," Katerina told me this week. "But I'm very sad because at the moment I cannot buy a dress. My boss promised me that he's going to give money to buy a dress. So I'm waiting."
