Stephen Hawking has started the biggest project to date to search for intelligent life outside of planet Earth. The initiative was announced Monday at The Royal Society in London.

The 10-year search is called "Breakthrough Listen" and will scan 1 million stars closest to Earth, the center of our galaxy, and "the entire galactic plane" for broadcast signals, according to a press release. The technology astronomers will use can also detect a laser that only requires the energy use of a 100-watt light bulb.

I'm Arun Rath.

UNIDENTIFIED MAN #1: Moscow is go for docking. Houston is go for docking. It's up to you guys. Have fun.

South Africa's coast is well known as the haunt of sharks, particularly the fearsome great white.

Even so, an encounter today between a large shark and Australian surfer Mick Fanning, who was competing in the Jeffreys Bay World Surf League competition (the J-Bay Open), broadcast live on television, has caused a few hearts to skip a beat.

Efforts to find a treatment for Alzheimer's disease have been disappointing so far. But there's a new generation of drugs in the works that researchers think might help not only Alzheimer's patients, but also people with Parkinson's disease and other brain disorders.

Flowers, bugs and bees: Stephen Buchmann wanted to study them all when he was a kid.

"I never grew out of my bug-and-dinosaur phase," he tells NPR's Arun Rath. "You know, since about the third grade, I decided I wanted to chase insects, especially bees."

These days, he's living that dream. As a pollination ecologist, he's now taking a particular interest in how flowers attract insects. In his new book, The Reason for Flowers, he looks at more than just the biology of flowers — he dives into the ways they've laid down roots in human history and culture, too.

In this installment of NPR's series Inside Alzheimer's, we hear from Greg O'Brien about his decision to sell the home where he and his wife raised their three children. O'Brien, a longtime journalist in Cape Cod, Mass., was diagnosed with early onset Alzheimer's disease in 2009.

Greg and Mary Catherine O'Brien have lived in their house on Cape Cod for more than 30 years. It's their dream house. They used to imagine growing old there.

Iran's supreme leader, Ayatollah Ali Khamenei, signaled his all-important approval of a historic nuclear deal forged with the West, but he portrayed the agreement as having been on Tehran's terms.

"Our policy toward the arrogant U.S. government won't change at all," Khamenei said in televised a speech in Tehran marking Eid, the end of Ramadan.

Pluto turns out to be pretty lively.

Not Las Vegas, perhaps, but more vivacious with geologic activity than we've ever known about, and for good reason: Pluto is currently almost 3 billion miles away from Earth, a dwarf planet spinning in the lonely last ring of our solar system.

This isn't your average top 30 list. No Taylor Swift song is on it, it doesn't involve sports and it's not a listicle of the Internet's best cat videos. But it does have a device that adds chlorine to water so it's safe to drink — and a condom tied to a catheter that can stop bleeding when a woman is having a baby.

What happens when you drop a regulation Spalding basketball from a 415-foot-high dam? It depends.

For a group from the trick basketball team How Ridiculous who sank a basket from atop the Gordon Dam in Tasmania, it meant landing a spot in the Guinness World Records book.

Pluto looks to be a far cry from the dead body that many scientists had long presumed. As the New Horizons probe continues to report back from the fringes of the solar system, a word that Mr. Spock might have used sums up the reaction: fascinating.

About Jon Foley's TED Talk

Ecologist Jon Foley says agriculture is the "most powerful force unleashed on this planet since the end of the ice age." He says we're using too much of it to irrigate, and we have to rethink how we farm.

About Ramanan Laxminarayan's TED Talk

Antibiotics save lives, but we rely on them too much. Eventually, the drugs may stop working. Economist Ramanan Laxminarayan asks us to think twice before reaching for this double-edged resource.

About Mark Plotkin's TED Talk

The isolated tribes of the Amazon are getting dispersed or dying out. Ethnobotanist Mark Plotkin describes what we'll lose if their culture and collective wisdom vanish with them.
