At night, in the ocean, they look like little Broadway billboards with dazzling trills of rainbow colored light. They have eight little runways on their bodies for light display. What are they?
They're called comb jellies. They're not jellyfish. They don't pulse like jellies. They seem to hang. You can find them bobbing off eastern beaches from Massachusetts to the Carolinas and if you pull them up (you can, they don't sting), they're goopy, gelatinous clumps vaguely shaped like walnuts.
Every year, people add 30 billion tons of carbon dioxide to the air, mostly by burning fossil fuels. That's contributing to climate change. A few scientists have been dreaming about ways to pull some of that CO2 out of the air, but face stiff skepticism and major hurdles. This is the story of one scientist who's pressing ahead.
"Zombie Apocalypse? What the hell are you talking about?"
It was our weekly astronomy group lunch when everyone, from the professors down to the undergrads, gets together for pizza. I'm not quite sure how the conversation took this turn, but at some point I quipped: "But of course that's after the Zombie Apocalypse."

I don't mean our private lives, our personal choices and hopes, the plans we make along the years. I imagine that each and every one of us believes our lives do have a purpose, or many. What I mean is life as a natural phenomenon, this strange assembly of matter endowed with autonomy, capable of absorbing energy from the environment and preserving itself through reproduction.

It won't be quite like Bruce Willis in Armageddon, but maybe you'll feel just as much a hero.
The White House and NASA are seeking the public's help in hunting for asteroids that could someday smash into Earth. They're also looking for a perfect space rock to capture so that astronauts could go there and study it.
Jiroemon Kimura, of Kyotango, Japan, was born in April 1897, lived right through the 20th century and died last Wednesday. He was 116. According to Guinness World Records (which searches for these things), he was the last surviving male born in the 1800s. All the other boys from that century, as best we know, are dead.
This week, the U.S. Fish and Wildlife Service proposed a new rule that would extend "endangered species" protections to chimpanzees held in captivity. Nearly half of all the chimps in the U.S. live in research facilities, and the regulation changes would make it more difficult to use these animals in medical experiments.
Australian archaeologists using remote-sensing technology have uncovered an ancient city in Cambodia that has remained hidden for more than a millennium under dense jungle undergrowth.
The discovery of Mahendraparvata, a 1,200-year-old lost city that predates Cambodia's famous Angkor Wat temple complex by 350 years, was part of the Hindu-Buddhist Khmer Empire that ruled much of Southeast Asia from about 800 to 1400 A.D., during a time that coincided with Europe's Middle Ages.

The Bracken Bat Cave, just north of San Antonio, is as rural as it gets. You have to drive down a long, 2-mile rocky road to reach it. There's nothing nearby — no lights, no running water. The only thing you hear are the katydids.
The cave houses a massive bat colony, as it has for an estimated 10,000 years. Bat Conservation International, the group that oversees the Bracken Cave Reserve, wants it to stay secluded, but the area's rural nature could change if a local developer's plan moves forward.

I've been to New Delhi where traffic is frightening. I've seen pictures of Nairobi and Bangkok, where it's even scarier. But Ho Chi Minh City? The town we used to call Saigon? I don't think I'd put myself in a truck, car, bike or even a Sherman tank in that town. This video opens in the scariest traffic circle I could imagine — actually, it's beyond imagining — where bikes, cars and people seem simultaneously, collectively and individually heading straight at each other (when you look, just count the vehicles and people on collision course; there are at least two or three in every frame).
Last month, we told you about companies that are growing salmon on dry land. That's an effective — but expensive — way to reduce water pollution caused by fish farms. After all, marine aquaculture provides about half of the seafood we eat.
The origin of the first primates — the group that includes humans, apes and monkeys — is thought to lie in the deep past, about 55 million years ago.
Fossils from that period are rare. But now, there's an exciting new one. It's called Archicebus achilles, roughly meaning "beginning long-tailed monkey." Actually, this creature lived before the monkeys we know of today, a mere 10 million years after the dinosaurs died out.
