Although fractions are thought to be a difficult mathematical concept to learn, the adult brain encodes them automatically without conscious thought, according to new research in the April 8 issue of The Journal of Neuroscience.

Microbloggers may think they're interacting in one big Twitterverse, but researchers at Carnegie Mellon University's School of Computer Science find that regional slang and dialects are as evident in tweets as they are in everyday conversations.

UCLA scientists have found that for computer-savvy middle-aged and older adults, searching the Internet triggers key centers in the brain that control decision-making and complex reasoning. The findings demonstrate that Web search activity may help stimulate and possibly improve brain function.

How do you weigh the biggest black holes in the universe? One answer now comes from a completely new and independent technique that astronomers have developed using data from NASA's Chandra X-ray Observatory.

The universe is full of water, mostly in the form of very cold ice films deposited on interstellar dust particles, but until recently little was known about the detailed small scale structure.

Designing an all-terrain robot for search-and-rescue missions is an arduous task for scientists. The machine must be flexible enough to move over uneven surfaces, yet not so big that it's restricted from tight spaces. It might also be required to climb slopes of varying inclines. Existing robots can do many of these things, but the majority require large amounts of energy and are prone to overheat

When it comes to public issues pertaining to science and technology, "talking it out" doesn't seem to work. A new study from North Carolina State University shows that the more people discuss the risks and benefits associated with scientific endeavors, the more entrenched they become in their viewpoint – and the less likely they are to see the merit of other viewpoints.

Whether condoms or abstinence, most efforts to prevent sexually transmitted diseases have a common logic: keep the pathogen out of your body altogether. While this approach is certainly reasonable enough, it doesn't help the countless people worldwide who, for a number of reasons, are not in a position to control their sexual circumstances.

A mat of nanowires with the touch and feel of paper could be an important new tool in the cleanup of oil and other organic pollutants, MIT researchers and colleagues report in the May 30 online issue of Nature Nanotechnology.

Just as the Occupy Wall Street movement has brought more attention to financial disparities between the haves and have-nots in American society, researchers from Indiana University and the University Medical Center Utrecht in The Netherlands are highlighting the disproportionate influence of so called "Rich Clubs" within the human brain.

The largest randomized study of breastfeeding ever conducted reports that breastfeeding raises children’s IQs and improves their academic performance, a McGill researcher and his team have found.

Corn and soybean farmers not only survived last year's epic drought — thanks to crop insurance, they made bigger profits than they would have in a normal year, a new analysis finds. And a big chunk of those profits were provided through taxpayer subsidies.
Linguists used to think the human brain had a specific region devoted to understanding language. But brain scans now indicate that regions controlling vision, movement, taste, smell and touch are all called into action when we think of a word, too.
Pachyderms' metabolism offers clues to dinosaur behavior
Fourteen-year-old "Jane" was likely eaten by starving colonists after she died
A breathtaking new video captures a crisp evening descending into a star-strewn night in Death Valley National Park last month. This new production from Sunchaser Pictures -- the team that brought you Death Valley DreamLapse -- features two desert enigmas: ...
A deep dive into the nature and complications of alt fuels like fracked natural gas, methane hydrate, and tar sands oil
A new bill moving through Congress would give the authorities unprecedented access to citizens' information.
A vast geologic formation in three northern Plains states contains twice as much oil and three times as much natural gas as the federal government previously estimated, according to a reassessment of the area released by the Interior Department Tuesday.
A material called boron nitride - originally touted as useful for next-generation electronics - turns out to be a high-performance pollutant "sponge".
A plastic smartphone screen cover patterned with tiny lenses could help mobile 3-D take off.Last week, a company in Singapore began shipping $35 plastic screen protectors for the iPhone 5. These are no ordinary screen protectors, though—each has half a million tiny lenses precisely patterned on its surface, which can turn an ordinary phone into a device capable of displaying 3-D images and video, no glasses required.
At conference starting Wednesday, huge trove of research papers point to enormous possibilities, but privacy issues remain.Cell phones generate tremendous amounts of human mobility and other data that can be particularly useful in the developing world to redesign transportation networks (see “African Bus Routes Redrawn Using Cell-Phone Data”) and provide a boon to epidemiology (see “Big Data from Cheap Phones”).
The golf-cart-sized space explorer put itself in standby mode after sensing a problem on April 22 after routine maintenance
NASA is paying $424 million more to get U.S. astronauts into space, and agency is blaming Congress for extra expense
NASA scientists say a massive storm on Saturn's North Pole looks just like a hurricane on earth, spinning counter-clockwise. Its eye is 20 times bigger than the ones we see on Earth.
SpaceX calls it the "Grasshopper" — it's a rocket that doesn't fall back to Earth haphazardly after launch. It carefully returns itself to the launchpad standing up, right where it started.
