Using a one-of-a-kind instrument designed and built at the National Institute of Standards and Technology (NIST), researchers have “unveiled” a quartet of graphene’s electron states and discovered that electrons in graphene can split up into an unexpected and tantalizing set of energy levels when exposed to extremely low temperatures and extremely high magnetic fields. Published in this week’s issue of Nature,* the new research raises several intriguing questions about the fundamental physics of this exciting material...
UAHuntsville was one of six institutions chose last week by NASA to provide scientific leadership on the Solar Probe Plus.
Gary Zank, Pei Ling Chan Eminent Scholar in Physics and director of UAHuntsville's Center for Space and Aeronomic Research, said this project is one of history’s most significant research initiatives regarding the sun.
Well ... maybe not teenage, but as fat summer tomatoes dangle in profusion from vines in gardens and farms across the country, researchers at Wake Forest University are looking for a way to make future harvests hold up better against drought or lack of nutrients.But the tomatoes these researchers study, with names like Never Ripe and Green Ripe, are mutants that will never achieve that wonderful red that makes a perfect summer meal for many...
Using two of the planet's largest, creative online communities -- World of Warcraft gamers and Etsy artists -- as their laboratory, two Indiana University Bloomington researchers hope to understand how the inner workings of such massive, networked collaborations could benefit scientists, corporations and the very IT designers who facilitated the success of the two online communities.
"Massive communities of creativity like those represented by World of Warcraft (WoW) and Etsy have a structurally different model from...
New research from NASA's Spitzer Space Telescope reveals that asteroids somewhat near Earth, termed near-Earth objects, are a mixed bunch, with a surprisingly wide array of compositions.Like the chocolates and fruity candies inside a piñata, these asteroids come in assorted colors and compositions. Some are dark and dull; others are shiny and bright. The Spitzer observations of 100 known near-Earth asteroids demonstrate that their diversity is greater than previously thought.
The brain has been mapped to the smallest fold for at least a century, but still no one knows how all the parts talk to each other. A study in Proceedings of the National Academy of Sciencesanswers that question for a small area of the rat brain and in so doing takes a big step toward revealing the brain’s wiring.
Burning the candle at both ends for a week may take an even bigger toll than you thought. Researchers at the University of Wisconsin-Madison have found that five nights of restricted sleep -- four hours a night -- affect the brain in a way similar to that seen after acute total sleep deprivation.
What if trains, planes, and automobiles all were powered simply by the air through which they move? Moreover, what if their exhaust and byproducts helped the environment?
ell, such an energy-efficient, self-propelling mechanism already exists in nature. The salp, a smallish, barrel-shaped organism that resembles a kind of streamlined jellyfish, gets everything it needs from the ocean waters to feed and propel itself. And, scientists believe its waste material may actually help remove carbon dioxide (CO2)...
When fire burns down a forest, nitrate levels go up, and the effects are persistent, according to recent research from University of Montana scientists. They found that charcoal deposited during fire events has the potential to stimulate the conversion of ammonia to nitrates, an important step in the nitrogen cycle.
For the first time, scientists have been able to measure the amount of water that rises and falls annually in the Amazon River floodplain.
The result -- 285 billion metric tons, or 285 cubic kilometers of water by volume -- sounds like a lot. That amount is over half the volume of Lake Erie, which is the world’s 15th largest lake.
