In the quest to make sun power more competitive, researchers are designing ultrathin solar cells that cut material costs. At the same time, they’re keeping these thin cells efficient by sculpting their surfaces with photovoltaic nanostructures that behave like a molecular hall of mirrors.
In a new video, scientists explain the chemistry behind marijuana's high, and investigate what scientists are doing to ensure legalized weed won't send users on a bad trip.
Using a two-step technique, scientists have produced a low-cost and simple approach for coating metallic surfaces with an enduring superhydrophobic film of copper.
With a new, commercially available camera system using nanoparticles that make cancer cells glow, the way is lit for surgeons to diagnose and remove tumors.
“Here’s some of the stories trending This Week at NASA!” A Dragon takes flight With a roar from its American Falcon 9 engines, SpaceX’s Dragon cargo ship blasted off from Space Launch Complex 40 at Florida’s Cape Canaveral Air Force Station on Friday to rendezvous with the International Space Station. The unmanned cargo vessel is carrying almost 5,000 pounds of scientific experiments and supplies for the Expedition 39 crew and should arrive at the orbiting laboratory on Sunday. Pad 39A Milestone
After a wait of more than 13 years, the ninth drop of pitch collided ever so slowly with the eighth drop in the Pitch Drop Experiment. The experiment was set up in 1927 to demonstrate that solid materials can flow like liquids.
A new design for nuclear plants built on floating platforms, modeled after those used for offshore oil drilling, could help avoid disasters in the future. Such floating plants would be designed to be automatically cooled by the surrounding seawater in a worst-case scenario, which would indefinitely prevent any melting of fuel rods, or escape of radioactive material.
We can learn a lot about volcanoes by studying explosions. The more we can learn about their explosive behavior, the more chance we have of saving lives when they suddenly erupt.
In a new video, researchers look at the science behind the world's most popular drug, caffeine, including why it keeps you awake and how much is too much.
A new study reveals how the brain achieves focused attention on faces or other objects: a part of the prefrontal cortex known as the inferior frontal junction controls visual processing areas that are tuned to recognize a specific category of objects.

Researchers, working at the famous La Brea Tar Pits, are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today.
