NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland."
A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise.
Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket.
Scientists look at past climates to learn about climate change and the ability to simulate it with computer models. One region in particular that has received a great deal of attention is the Indo-Pacific warm pool, the vast pool of warm water stretching along the equator from Africa to the western Pacific Ocean.
Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon.
The smart electric fortwo – billed as the least expensive electric vehicle on the U.S. market – is making its way to dealership, Mercedes-Benz USA said this week, with an interesting twist: You can buy the car without a battery if you want to.
How many rings do you see in this new image of the galaxy Messier 94 (below), also known as NGC 4736? While at first glance one might see a number of them, astronomers believe there is just one. This particular image was captured in infrared light by NASA's Spitzer Space Telescope.
In the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable energy sources has been achieved.
Tesla Motors is riding a bit of a high mark on a wave lately, recently having very favorable first quarter financial results.
Scientists have created the first global topographic map of Saturn's moon Titan, giving researchers a valuable tool for learning more about one of the most Earth-like and interesting worlds in the solar system. The map was recently published as part of a paper in the journal Icarus.
Can math models of gaming strategies be used to detect terrorism networks? The answer is yes, at least according to a paper in the SIAM Journal on Discrete Mathematics.
Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries.
A new window into the nature of the universe may be possible with a device proposed by scientists at the University of Nevada, Reno and Stanford University that would detect elusive gravity waves from the other end of the cosmos.
NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.
The type of sensors that pick up the rhythm of a beating heart in implanted cardiac defibrillators and pacemakers are vulnerable to tampering, according to a new study conducted in controlled laboratory conditions.
Generating electricity isn’t limited to burning things, making steam, or harnessing the power of wind, wave, and sun—even though these are by far the most common ways of doing so.
A giant black hole in the center of the galaxy 4C+29.30 is generating two powerful jets of particles.
Two research teams at the National High Magnetic Field Laboratory (MagLab) smashed through a nearly 40-year barrier recently when they observed a never-before-seen energy pattern.
Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across.
Chances are you know how many miles your car logs for each gallon or tankful of gas, but you probably have only a foggy idea of how much energy your house consumes, even though home energy expenditures often account for a larger share of the household budget.
