Science paper examines role of aerosols in climate change
A group of scientists affiliated with the International Geosphere-Biosphere Programme (IGBP) have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models.   view more (2008-09-08)

Dirty air brings rain -- then again, maybe not
An international team of scientists, headed by Prof. Daniel Rosenfeld of the Institute of Earth Sciences at the Hebrew University of Jerusalem, has come up with a surprising finding to the disputed issue of whether air pollution increases or decreases rainfall. The conclusion: both can be true,... view more (2008-09-08)

Next Stop: The Fourth Dimension
How did the universe come to be? What is it made of? What is mass? Can science prove that there are other dimensions?   view more (2008-09-04)

Putting the squeeze on nitrogen for high energy materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen.   view more (2008-09-04)

Cosmic connections: Imperial scientist locates the origin of cosmic dust
The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space.   view more (2008-09-03)

Scientists grow 'nanonets' able to snare added energy transfer
Using two abundant and relatively inexpensive elements, Boston College chemists have produced nanonets, a flexible webbing of nano-scale wires that multiplies surface area critical to improving the performance of the wires in electronics and energy applications.   view more (2008-09-03)

PET scans help identify mechanism underlying seasonal mood changes
Brain scans taken at different times of year suggest that the actions of the serotonin transporter-involved in regulating the mood-altering neurotransmitter serotonin-vary by season, according to a report in the September issue of Archives of General Psychiatry, one of the JAMA/Archives journals.   view more (2008-09-02)

Children's calorie expenditure, heart rate increase during active video games
Children burn more than four times as many calories per minute playing an active video game than playing a seated game, and their heart rate is also significantly higher with the active game.   view more (2008-09-02)

Breaking harmful bonds
Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even... view more (2008-08-29)

Scientists reveal effects of quantum 'traffic jam' in high-temperature superconductors
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, in collaboration with colleagues at Cornell University, Tokyo University, the University of California, Berkeley, and the University of Colorado, have uncovered the first experimental evidence for why the transition... view more (2008-08-28)

DOE official cites need for major breakthroughs to cope with climate change
Meeting the world's growing energy needs while responding to global warming during the 21st Century will be one of the biggest challenges humanity has ever faced, Raymond L. Orbach, Ph.D., the U.S. Department of Energy's Under Secretary for Science, says in the latest podcast in the American... view more (2008-08-27)

Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight.   view more (2008-08-25)

Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria.   view more (2008-08-25)

Joslin study identifies protein that produces 'good' fat
A study by researchers at the Joslin Diabetes Center has shown that a protein known for its role in inducing bone growth can also help promote the development of brown fat, a "good" fat that helps in the expenditure of energy and plays a role in fighting obesity.   view more (2008-08-21)

Light touch: Controlling the behavior of quantum dots
Researchers from the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI), a collaborative center of the University of Maryland and NIST, have reported a new way to fine-tune the light coming from quantum dots by manipulating them with pairs of lasers.   view more (2008-08-20)

OU Researchers Isolate Microorganisms That Convert Hydrocarbons to Natural Gas
When a group of University of Oklahoma researchers began studying the environmental fate of spilt petroleum, a problem that has plagued the energy industry for decades, they did not expect to eventually isolate a community of microorganisms capable of converting hydrocarbons into natural gas.   view more (2008-08-20)

Polymer electric storage, flexible and adaptable
The proliferation of solar, wind and even tidal electric generation and the rapid emergence of hybrid electric automobiles demands flexible and reliable methods of high-capacity electrical storage. Now a team of Penn State materials scientists is developing ferroelectric polymer-based capacitors... view more (2008-08-20)

New climate record shows century-long droughts in eastern North America
A stalagmite in a West Virginia cave has yielded the most detailed geological record to date on climate cycles in eastern North America over the past 7,000 years.   view more (2008-08-19)

MSU's discovery of plant protein holds promise for biofuel production
Scientists at Michigan State University have identified a new protein necessary for chloroplast development. The discovery could ultimately lead to plant varieties tailored specifically for biofuel production.   view more (2008-08-18)

Universally Speaking, Earthlings Share a Nice Neighborhood
We don't have spacecraft to take us outside our solar system--not yet, at least. Still, astronomers thought they had a pretty good understanding of how our solar system formed and in turn, how others formed.   view more (2008-08-11)

Flexible nanoantenna arrays capture abundant solar energy
Researchers have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. The technology, developed at the U.S. Department of Energy's Idaho National Laboratory, is the first step toward a solar energy... view more (2008-08-11)

Improved reaction data heat up the biofuels harvest
High food prices, concern over dwindling supplies of fossil fuels and the desire for clean, renewable energy have led many to seek ways to make ethanol out of cellulosic sources such as wood, hay and switchgrass.   view more (2008-08-07)

New JILA technique reveals hidden properties of ultracold atomic gases
