A long record of atmospheric observations has put an "official" stamp on the foundation of climate-change science: the greenhouse effect really works the way we've always said it does.
Scientists must play catch-up to industry as we figure out ways to use the deep underground without triggering earthquakes.
Our best climate models, combined with our best climate records, foresee at least a century of profound drought in the Midwest and Southwest.
In the Internet age, many scientists are questioning the traditional publishing model. As we flounder through the digital revolution, it's intriguing to look back at the print revolution of the early Renaissance, which created comparable social and scientific upheaval.
The large asteroid Vesta has added flows of material rich in water to its bag of tricks. It's just one more way this small world acts like a proper planet.
For geologists, even with the advent of modern technology, there are instances when older methods are more effective; picks and shovels are sometimes the best complementary tools available for trenching studies.
A reassessment of historical data suggests that compared to previous estimates, the world's sea level rose more slowly during the 20th centuryand is rising faster now.
A new way of measuring soil erosion in the geologically recent past, before modern civilization, may help put sustainable agriculture on a firmer footing.
A new set of rock dates have pushed volcanism back into the debate over the extinction of the dinosaurs.
A new book about marine invertebrates celebrates the sumptuous beauty of our lesser-known cousins.
The just-released seismic resiliency plan for Los Angeles goes beyond just saving lives; it hopes to ensure that the nation's second-largest city will still work after a magnitude 7.8 earthquake.
Thanks to a meteorite collected in 1879, we have finally given a name to the most abundant mineral in Earth. Here's why it took so long to christen this stuff.
The cutting edge in earthquake research is mapping our most important faults in three-dimensional detail. A new paper finds some key hidden links in the Bay Area's fault system.
Migratory monarch butterfly populations have fallen into a tailspin in recent years. Scientists fear that in a classic case of good intentions gone awry, efforts to help the beleaguered butterflies may be inadvertently making matters worse by changing their behavior.
If you want to go to Mars but can’t quite afford the hundreds of billions of dollars for a ticket, there is another solution: consider instead a trip to the Atacama Desert in Chile.
Helix, a Los Altos "community science center" run by the Exploratorium, will close its doors on November 30. The 5,000-square-foot space brought hands-on science exhibits, a classroom with ever-changing activities and a museum gift shop to downtown Los Altos.
When a court convicted earthquake scientists of manslaughter, seismologists everywhere feared the worst for their own efforts at informing the public. After the convictions were overturned on appeal this week, experts, journalists and the general public can consider the wider lessons learned.
Oakland gains character as well as affordable housing from its stock of small and mid-sized apartment buildings. A retrofit plan is being prepared to strengthen this crucial part of the city's fabric against earthquake damage.
