On a research voyage through the Arctic ice cap, a scientist has a eureka moment, one that he hopes will help solve some of the riddles about Arctic ice melt — and what's ahead for the rest of the planet as the climate warms up.
To most people, eliminating snacks between meals seems like a logical way to reduce calorie intake and perhaps lose weight. But new research suggests the amount of calories you eat may not be as important as when you eat them.
The Curiosity rover is currently roaming a 96-mile crater on the surface Mars, and the evidence it has collected suggests that the crater was once home to a huge lake. And NASA scientists say this information is unlike any they've seen before.
Seals spend a lot of time in the water — which makes them nearly ideal vehicles for gathering data on ocean currents and changes in ocean conditions. But doing that requires a little bit of cooperation from the seals.
It's her ocean — we're just swimming in it. A Great White Shark named Lydia had a tracking device attached to her dorsal fin last year. Since then, she's logged over 27,000 miles and now she even has her own Twitter account.
Two Lebanese sisters have been interviewing accused terrorists in Lebanon’s Roumieh prison. They hope to understand what pushes people to become holy warriors. And they have found a common theme among the men —absent or abusive dads.
Our definition of art is outdated: we still believe art and science are two entirely separate cultures whose ideas rarely intersect. Now, in the 21st century, it’s time to revisit that thinking, a new book argues.
For the first time, the US Navy has deployed a laser weapon on the high seas, ready to fry any drones or speedboats that might dare to attack. It's still a prototype for now, but it could be a first step in a new, lethal — and relatively cheap — era of naval combat.
Texas is the biggest climate polluter in the U.S. It’s also is also extremely vulnerable to some of the impacts of climate change. But the state’s most prominent politicians say they don't believe that climate change is real. It all adds up to a big problem for Texas and the rest of us.
Genetically modified crops are a big part of both our food supply and our debates about health and safety. But some scientists and observers argue those debates are getting the science of GMOs wrong, and grouping together crops that don't belong in the same argument.
Italy is a fiercely anti-GMOs. It's one of a handful of countries to ban them outright. But European law is trumping them, and it has opened a window for one Italian farmer who is growing GMO corn anyway.
Plants have senses that put humans to shame. Not only do they hear (yes, it's true) and smell, they can also sense the presence of water, and even an object in their space. Now new research suggests that plants can actually learn and remember.
Scientists say a massive ice sheet in Antarctica is starting to collapse. It's not going to slide into the ocean over night, but rather over centuries. Still, it will fall, scientists say. It's gotten to the point it can't be stopped — and that means rising sea levels.
The new NOVA special, "Vaccines: Calling the Shots," explores the lingering global resistance to vaccination campaigns. Case studies from around the world explain just how bad the impact can be when groups opt out of childhood shots.
Half of North America's 650 bird species may be forced to change their current habitats because of climate change or perish — including the bald eagle and the common loon. A new Audubon Society study produced maps to show people which of their local birds are at risk.
When India celebrated the success of its first Mars mission, a photo of middle-aged female scientists draped in saris became the viral face of that triumph. But that doesn't mean female scientists face an easy path, and Rhitu Chatterjee says much more needs to be done for gender equality.
We're looking for a firth, not a fourth or fifth, but a firth in Scotland. It's Scotland's largest firth, a triangle shaped inlet of the North Sea. It's home to dolphins that use signature whistles to greet or contact other individual dolphins.
Months before both this year's record Arctic ice melt and Hurricane Sandy, a climatologist identified changing weather patterns that suggest links between the two seemingly separate events. Sam Eaton reports from New Jersey.
The answer to today's Geo Quiz is Basel, Switzerland. The city was home to Swiss chemist Albert Hofmann, who died yesterday. The World's David Leveille reports that Hofmann's discovery of LSD remains controversial.
Turns out that animals lie. At least fiddler crabs do, according to a new study by Australian scientists. The BBC's Matt McGrath tells anchor Lisa Mullins how growing a fake claw helps male fiddler crabs win mates and avoid fights.
The answer to today's Geo Quiz is the Egyptian city of Luxor located at the site of the ancient city of Thebes. Mummies from the Brooklyn Museum had a CAT scan this week. Lisa Mullins gets the story from the museum's Egyptian art curator Edward Bleiburg.
Dubai opened the Arab Peninsula's first metro system today. It's to become the world's longest driverless train system. Anchor Marco Werman speaks with John Alexander Smith, professor of Architecture and Interior Design at American University in Dubai.
