Disease diagnosis often requires expensive equipment and tests to probe deep inside the body. But a new test relies on a fast, cheap and easy technique. And its answers appear on a strip of paper — just as they do on a pregnancy test.
A novel material can alter how easy it is to change data stored on it, based on temperature. One immediate application: more secure hard drives for computing.
A new map may explain why some brain injuries are worse than others. Even relatively minor injuries that disrupt message superhighways may have a more devastating impact than some seemingly catastrophic injuries.
By neutralizing the poison produced by fire ants, ‘crazy’ ants can survive heated battles. And that may help explain why crazy ants are edging out fire ants in parts of the southern United States.
Boys develop autism at four times the rate seen in girls. Girls’ genes are better protected from the mutations linked to this brain disorder, data now suggest.
It’s the first time astronomers have ever detected a cluster of stars moving collectively at such speed.
Woolly mammoths roamed the Arctic until about 10,000 years ago. Why they died out may trace to the vanishing of the mostly flowering plants on which they had been dining.
Many companies have moved the plants that make their products to developing countries, such as China. But the pollution linked to making those products can travel around the world.
Eating small amounts of peanuts may help people overcome an allergy to the food. But for most people undergoing the treatment, its benefits vanish after they stop eating peanuts.
Buildings in the United States can be deadly obstacles to flying birds. A new study estimates that as many as 1 billion birds die every year after colliding with windows. And low buildings — not skyscrapers — account for most of those deaths.
Jaws may scare beachgoers. But sharks bring a smile to some environmental scientists, who are using the toothy fishes to collect data on the ocean.
Scientists blasted a tiny capsule of hydrogen with laser beams, setting off a reaction that released more energy than in earlier experiments. Still, scientists remain a long way from creating a reaction that releases more energy than it needs to get started.
Polar animals are encountering new, killer parasites as melting ice unlocks their access to new hosts.
Twenty-one years ago, a minnow facing a high risk of extinction was placed on the U.S. Endangered Species List. With help from scientists, the fish appears to have largely recovered. It’s the first ‘listed’ fish to do so.
Ten years in to its tour of Mars, the Opportunity rover finds another place on the Red Planet that once might have hosted water.
Scientists have figured out how to turn a specialized cell into any other type of cell the body may need. All it may take is an acid bath.
Scientists proved that lasers can be used to harness materials into a reflective surface. Some scientists ask: Can a space mirror be far away?
Thinking heavy thoughts? Scientists have just put people on a balance and shown that the brain briefly gains blood — becoming a bit heavier — while concentrating.
Scientists occasionally describe the dog paddle as a “trot,” but that’s not right. When dogs swim, their complicated leg motions look more like a frantic run.
The world’s oldest library has books with hidden texts. Researchers are now using a high-tech approach to reveal their long-masked words.
A new study sparks debate about how much rubble on a mountainside has been blasted loose by powerful bolts from the sky.
Scientists have just begun probing the preserved tissue from “H.M.” Even five years after he died, this man’s brain continues to offer lessons on how people make — or fail to make — memories.
Astronomers may have finally figured out why predictions of the amount of matter in the universe don’t match observations. A huge amount may hide in the gas clouds that surround galaxies.
This hard tissue is more than just a quiet scaffold for your organs and protective helmet for your head. It’s active and ‘chatty,’ influencing other tissues.
Genes from an ancient skeleton suggest that dark-skinned people may have been the first to evolve blue eyes.
Scientists may have unearthed the source of Mima mounds, mysterious bumpy landscapes found on every continent except Antarctica.
Forty high-school seniors learn they have been named finalists in the March Intel Science Talent Search competition.
A supernova first spotted in 1987 produced a huge cloud of space dust. Astronomers are now finding clues in it to how stars formed in the early universe.
The nicotine in tobacco that poisons some creatures can also act as a chemical defense — at least for some caterpillars. The bad breath it gives these insects repels natural predators, such as spiders.
Electric-car designers think they’ve found a way to replace the differential. Computer-controlled wheels and a bevy of electronic sensors now help take the place of old-school gears.
