Need another reason to eat your greens (and yellows and oranges) as part of a healthful diet in the New Year? A large U.S. study has found that adults with higher concentrations of serum alpha-carotene in their blood were likely to live longer than those who had lower levels...
Ancient humans' lax dental hygiene has been a boon for researchers looking for clues about early diets. Traces of fossilized foodstuffs wedged between Neandertal teeth have revealed plentiful traces of grains and other plants, supporting the theory that these heavy-browed humans were not just meat-eaters...
Short answer? Not much.
In fact, while no single storm is anything more than weather, stronger winter storms are exactly what climate scientists expect from a warming climate...
Can chocolate-dipped strawberries be improved upon—genetically? Separate teams of researchers have sequenced the genomes of varieties of the two crops that make up this treat, finding key coding information that could help keep these sweets on dessert trays—and assist science in the meantime...
Our picks for the top 10 science stories of the year were published this week, but who cares what editors at Scientific American think? Below is a list of the stories and features that visitors to our Web site clicked on the most this year...
Finding Santa Claus's home at the North Pole is easy on a globe—just look for the point on top where all the lines of longitude meet. But that is just the "geographic" North Pole; there are several other definitions for the poles, all useful in different scientific or navigational contexts...
What can be gleaned from a fragment of a 30,000- to 50,000-year-old finger? With highly sensitive genetic sequencing technology, researchers now claim to have spotted a new form of extinct humans that were neither Neandertals nor modern humans...
The aftermath of burning a mountain of coal isn't pretty. It's not just the ash itself; it's also the toxic elements that have been purified by fire out of the "fossilized sunshine."Those toxic elements come along for the ride when the coal ash spills, like it did near Kingston, Tenn., on December 22, 2008...
Ocean acidification, the result of roughly a third of global CO2 emissions dissolving into the seawater and lowering its pH, has complicated and poorly understood consequences for ocean ecosystems...
Children with autism spectrum disorder (ASD) often exhibit a heightened ability to pick out patterns and excel at other visual-spatial tests. But a new study puts this presumption to the test in a more real-world scenario and finds that ASD kids are actually found wanting when it comes to search skills...
