Waters in the Gulf of Alaska were surprisingly acidic this summer, an indication they are absorbing high levels of carbon dioxide. Farther north, a polar bear in search of food wandered dangerously close to a town where it would have been killed.
FAJARDO, Puerto Rico—Part of the fun of coming to astronomy conferences is seeing the nonplussed reaction of local people in restaurants and bars--it's not often you get a crowd of people sweeping through your town to talk about Titanian lakes, lunar soil, and the prospects for life beyond the solar system.
Editor's Note: A team of Rensselaer Polytechnic Institute students traveled up New York's Hudson River on the New Clermont , a 6.7-meter boat outfitted with a pair of 2.2-kilowatt hydrogen fuel cells to power the boat's motor.
Thanks to the much-heralded International Year of Astronomy, this much we know: Galileo used a telescope to observe the moon in 1609. But the inventor of the revolutionary resolutionary device remains unknown, and its early history is muddied by simultaneous discoveries and competing claims.
The first doses of approved vaccines for the H1N1 "swine" flu will start trickling in across the U.S. on Tuesday. The first to arrive, 600,000 doses of MedImmune's FluMist nasal spray, will be for healthy people ages two to 49, the Associated Press reported.

The revolution in neuroscience is often characterized as a revolution in new imaging technology.A long overdue reassessment of neuroimaging machines—in particular the functional magnetic resonance imager—has underlined that what you see is not always what you get.A study published this year in Perspectives on Psychological Science noted that many papers in social neuroscience, the field that examines the neurobiology of social behavior, suffered from faulty analyses that produced "voodoo correlations" in their data.
In a pair of flybys by a robotic explorer last year, planetary scientists began to unravel some of the mysteries of Mercury, a planet that is difficult to study from Earth and that had not been visited by a spacecraft since the 1970s.
Current cancer screening often requires painful procedures and weeks of waiting to obtain results. But what if doctors could read a biological sample with a small hand-held device and come back with an answer in less than an hour?
Looking to create computer defenses that adapt well to the cat-and-mouse game played between computer users and cyber attackers, a team of researchers has turned to one of nature's most effective militias—ants.
