You've just won a prize. Would you like to find out what it is right away, or wait until later? A new study in the Journal of Consumer Research says most people are happier waiting.

Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years. The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles that occurred during that period.

Scientists believe they have discovered a key element in the development of chronic asthma. Their research explains why the structure and function of asthmatic airways are changed or ''remodeled'' and how this contributes to chronic asthma.

NASA's Swift satellite reported multiple blasts of radiation from a rare object known as a soft gamma repeater, or SGR. Astronomers have discovered a dead star belonging to a rare group: the magnetars.

Scientists have identified a new target for the diagnosis and treatment of age-related macular degeneration, the most common cause of blindness in older Americans.

A new type of robot being developed will make it easier to detect drugs, weapons, explosives and illegal immigrants concealed in cargo containers.

Homosexual behavior seems pointedly un-Darwinian. An animal that doesn't pass along genes by mating with the opposite sex at every, well, conceivable opportunity, seems to be at an evolutionary disadvantage. So what’s in it for the 450-plus species that go for same-sex sex? [More]

Bloomin' jellyfish! Overfishing, climate change and ocean dead zones may be downers for humans and other critters, but they turn out to be a boon for jellyfish schools, reports the recent "Jellyfish Joyride" paper in Trends in Ecology and Evolution. [More]

Alcohol-related deaths, heavy drinking episodes and drunk driving have all been on the rise on college campuses over the past decade, a new government study shows.

Scientists have used genetic engineering to tame one of the most deadly food poisoning microbes and turn it into a potential new way of giving patients medicine and vaccines in pills rather than injections.
