A substance found in nuts and whole grains may someday help doctors fight the kind of food poisoning that sickened thousands of people in Europe last summer, a study in mice suggests.
It's dramatic news when a marathon runner collapses with no pulse. Now a big study finds such calamities are rare and usually due to a pre-existing heart problem.
A prestigious scientific journal is retracting a controversial 2009 report that linked chronic fatigue syndrome to a virus.
Scientists have found two Earth-sized planets orbiting a star outside the solar system, an encouraging sign for prospects of finding life elsewhere.
Chennel King, a nurse from Norwalk, Conn., went Christmas shopping the other day with a new holiday companion: a budget.
As scientists struggle to find a vaccine to prevent infection with the AIDS virus, a study in mice suggests hope for a new approach — one that doctors now want to test in people.
Even if the worst nuclear accident in 25 years leads to many people developing cancer, we may never find out.
A map of radioactive contamination across Japan from the Fukushima power plant disaster confirms high levels in eastern and northeastern areas but finds much lower levels in the western part of the country, thanks to mountain ranges, researchers say
In recent years, scientists have learned that some patients believed to be in a vegetative state actually have some awareness and that they might be able to communicate. Now, a new study suggests a portable brain monitor can detect signs of this, perhaps making it possible someday for doctors to easily double-check the diagnosis at the bedside.
The Fukushima nuclear disaster released twice as much of a radioactive substance into the atmosphere as Japanese authorities estimated, reaching 40 percent of the total from Chernobyl, a preliminary report says.
Any dieter knows that it's hard to keep off weight you've lost. Now a study finds that even a year after dieters shed a good chunk of weight quickly, their hormones were still insisting, "Eat! Eat! Eat!"
George Eberhardt turned 107 last month, and scientists would love to know how he and other older folks like him made it that far. So he's going to hand over some of his DNA. He's one of 100 centenarians taking part in a project announced Wednesday that will examine some of the oldest citizens with one of the newest scientific tools: whole-genome sequencing, the deciphering of a person's complete collection of DNA.
Some questions and answers about the experiment that appeared to show particles speeding faster than light.
Early humans settled eastern Asia in two waves rather than just one, say two genetic studies that weigh in on a long-running debate among experts trying to trace the migrations of early humans.
It sounds like science fiction: While volunteers watched movie clips, a scanner watched their brains. And from their brain activity, a computer made rough reconstructions of what they viewed.
For almost 50 years, people have used insect repellents containing DEET. But scientists still argue about how the stuff works.
A scientist who discovered a powerful malaria drug and two others who illuminated how proteins fold within cells have won prestigious medical awards.
Scientists have made a promising advance for controlling dengue fever, a tropical disease spread by mosquito bites. They've rapidly replaced mosquitoes in the wild with skeeters that don't spread the dengue virus.
One of the world's most famous fossil creatures, widely considered the earliest known bird, is getting a rude present on the 150th birthday of its discovery: A new analysis suggests it isn't a bird at all.
Like a poodle on a leash, a tiny asteroid runs ahead of Earth on the planet's yearlong strolls around the sun, scientists report.
This may come as no surprise to residents of New York City and other big urban centers: Living there can be bad for your mental health.
Imagine being pregnant and taking a simple blood test that lays bare the DNA of your fetus. And suppose that DNA could reveal not only medical conditions like Down syndrome, but also things like eye color and height. And the risk for developing depression or Alzheimer's disease. And the chances of being gay.
The results of the blood test revealed only a risk, but when she saw them, she still threw up. Now she had to find out for sure.
Scientists say they've found cells in the hearts of mice that can make new muscle after a heart attack, raising hopes that doctors can one day help the human heart repair itself.
They exist for only seconds at most in real life, but they've gained immortality in chemistry: Two new elements have been added to the periodic table.
