Oceanographers spotted a dark, swirling mass in shallow waters off the coast of San Diego. It wasn't a red tide or an oil spill, but a massive school of anchovies.
The eight new astronauts are expected to man some of NASA's boldest, most anticipated new missions, including travel to Mars.
Zombie worms don't actually drill through bone, as was previously believed. Instead, their skin produces enough acid to dissolve the zombie worms' path through bone.
A study suggests that human-caused and natural global warming episodes affect rainfall rates differently. The finding could help scientists better forecast what's ahead.
Waste heat has a smaller impact on global climate than does CO2, but heat from highly urbanized northern regions appears to explain observed deviations from climate forecasts, a study says.
Heat from northern cities from New York to Tokyo could warm winters in Canada and Siberia, according to a new study, but cool the fall in the western US and Eastern Europe.
Researchers examined rocks collected by astronauts during NASA's Apollo lunar landing missions, as well as a meteorite that originated on the moon to make the find.
The wildfires devastating Colorado have been linked to a streak of unusually hot weather, but they that does not necessarily mean that global warming is the culprit.
While wildfires, hurricanes, tsunamis, and other emergency events leave behind devastation, they also create the impetus for investment in new technologies and life-saving innovation.
A multibillion-dollar flood-prevention system will be put in place starting next year, a decade after the project began.
