Coffee can teach us many things, including engineering. At the University of California, Davis, it's now the focus of the most popular elective class on campus and of an ambitious new research center.
We know that bacteria can become resistant to antibiotics, but we've never seen it happen. An MIT scientist figured out how to show bacteria surviving antibiotics and invading a giant petri dish.
To study dogs' brain activity, scientists had to train canines to hold absolutely still for eight minutes without restraint. But how do you get a dog to freeze that long inside a clanging MRI scanner?
The mission aims to circle a hill-sized asteroid for two years, then skim its surface and bring a hearty sample of 4.5 billion-year-old dirt back to Earth.

The celestial body was discovered in the same year Mercury died at age 45. It was dedicated to the singer in honor of what would have been his 70th birthday, his bandmate Brian May announced.
For decades a rare disease crawled across Papua New Guinea. When scientists realized what was behind kuru, it caught everyone by surprise. But similar diseases can still be transmitted through food.
We've all heard the adage that "power corrupts," but psychologist Dacher Keltner at UC Berkeley has found evidence to prove it. His book is The Power Paradox: How We Gain and Lose Influence.
Researchers from around the world are visiting Lake Huron to look at purple mats deep below the water's surface. They believe these mats could explain how the Earth's oxygen rich air developed 2.4 billion years ago.
Scientists knew that lizards, which bask in the sun for warmth, are vulnerable to climate change. A new study suggests the hazards are more complicated, and possibly worse, than previously believed.
More than any of today's icons — Bill Gates, Steve Jobs, Mark Zuckerberg and the rest — Guglielmo Marconi was uniquely at the center of the communication revolution of his time, says Marc Raboy.
Populations of Grauer's gorilla (formerly known as the eastern lowland gorilla) total only around 3,800 individuals — a 77 percent reduction — according to a recent survey.
Saturday's large quake immediately raised suspicions that it was linked to injection wells that oil and gas companies use as part of fracking and other operations.
