Top Brain Science Movies Revealed

Movies that showcase brain science often take a little artistic license in terms of their scientific accuracy — think "Being John Malkovich" or "The Matrix" — but even brain scientists say that these fanciful plots can make for good movies.

Oceans face 'deadly trio' of threats, study says

By Environment Correspondent Alister Doyle OSLO (Reuters) - The world's oceans are under greater threat than previously believed from a "deadly trio" of global warming, declining oxygen levels and acidification, an international study said on Thursday. The oceans have continued to warm, pushing many commercial fish stocks towards the poles and raising the risk of extinction for some marine species, despite a slower pace of temperature rises in the atmosphere this century, it said. ...

Gray Wolves May Lose Endangered Status, But Not Without a Fight

WASHINGTON — In passionate and at times tearful testimony at the U.S. Department of the Interior Monday night (Sept. 30), Americans who say they have admired, studied, defended and even kissed gray wolves offered a plea to federal officials: Don't take the animals off the endangered species list.

Honey Badger Don't Care About Camera Traps

With charismatic lions and leopards often stealing the spotlight, small predators in Central Africa sometimes get overlooked.

Polar Opposites: Why Climate Change Affects Arctic & Antarctic Differently

The sea ice around Antarctica reached a record high in August of 7.2 million square miles (18.6 million square kilometers) — the greatest extent observed since recordkeeping began in 1979.

Think You Know Your Close Pals? Think Again, Science Says

SAN FRANCISCO — How well do you know what your loved ones are thinking?

Incredible Technology: How to Clean Up Dangerous Space Junk

The vast amount of manmade debris in orbit around Earth is untenable, but emerging and currently available technologies could be used to get these objects under control.

Giant Impact That Formed the Moon Blew Off Earth's Atmosphere

The moon came into existence after several planet-size space bodies smashed into the nascent Earth one after the other, with the final one actually forming our satellite, while several impacts repeatedly blew off our planet's atmosphere, according to a new study.

'Poop Pills' May Halt Gut Infections

Bacteria extracted from human poop are the main ingredients of a new pill that may help treat patients who have difficult-to-cure intestinal infections, according to a new study from Canada.

The Milky Way galaxy reigns over Maine as a photographer looks on this spectacular view captured by a veteran observer of the night sky.

Scientist to Congress: Shutdown a 'Deep Hardship'

During her time as head of the U.S. Geological Survey, Marcia McNutt had to prep for many government shutdowns but never had to temporarily lay off any employees, as is happening under the current shutdown. Now, she's the editor of Science, one of the world's top science journals, and has the freedom to let Congress know what she thinks about the current budget impasse.

Spooky Vibrations: Finding Brings Quantum Computers a Bit Closer

Imagine that two people could get linked in such a way that they could influence each other no matter where in the universe they existed. Now scientists find they can entangle mechanical vibrations in this same way, findings that could help enable quantum computers far more powerful than normal computers.

Zapping the Brain Makes People Obey Social Norms

From dress codes to anti-incest laws, all human societies have social norms that specify how people should behave in various situations. Scientists have now shown that a zap of electricity to the brain can influence whether people choose to comply with these norms or not.
