Is global warming unstoppable?
In a provocative new study, a University of Utah scientist argues that rising carbon dioxide emissions - the major cause of global warming - cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day.   view more (2009-11-23)

Generating electricity from air flow
A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity.   view more (2009-11-23)

On the crest of wave energy
The ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency, and the need to be tethered to the seafloor.   view more (2009-11-20)

JQI researchers create entangled photons from quantum dots
To exploit the quantum world to the fullest, a key commodity is entanglement-the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another.   view more (2009-11-18)

Vibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize in Physiology or Medicine.   view more (2009-11-12)

UT Knoxville and ORNL researchers turn algae into high-temperature hydrogen source
In the quest to make hydrogen as a clean alternative fuel source, researchers have been stymied about how to create usable hydrogen that is clean and sustainable without relying on an intensive, high-energy process that outweighs the benefits of not using petroleum to power vehicles.   view more (2009-11-12)

Computer predicts reactions between molecules and surfaces, with 'chemical precision'
Good news for heterogeneous catalysis and the hydrogen economy: computers can now be used to make accurate predictions of the reactions of (hydrogen) molecules with surfaces. An international team of researchers, headed by Leiden theoretical chemist Geert-Jan Kroes, published on this subject this week in the journal Science.    view more (2009-11-09)

Energy gap useful tool for successful weight loss maintenance strategy
Americans continue to get heavier. Most weight control methods short of bariatric surgery are generally considered ineffective in preventing obesity or reducing weight.   view more (2009-11-05)

Toward home-brewed electricity with 'personalized solar energy'
New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities.   view more (2009-11-05)

Addressing obesity via the 'energy gap'
The November issue of the Journal of the American Dietetic Association features a commentary by James O. Hill, an honorary ADA member, professor of pediatrics and medicine and director of the Center for Human Nutrition at the University of Colorado-Denver.   view more (2009-11-04)

Precise picture of early Universe supports 'dark matter' theory
A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist.   view more (2009-11-03)

Starburst galaxy sheds light on longstanding cosmic mystery
An international collaboration that includes scientists from the University of Delaware's Bartol Research Institute in the Department of Physics and Astronomy has discovered very-high-energy gamma rays in the Cigar Galaxy (M82), a bright galaxy filled with exploding stars 12 million light years from Earth.   view more (2009-11-03)

LANL Roadrunner models nonlinear physics of high-power lasers
For years scientists have struggled with the difficult physics of inertial confinement fusion. This is the attempt to compress a target capsule containing isotopes of hydrogen with high-powered lasers to high enough pressure and temperature to initiate fusion burn.   view more (2009-10-29)

Plugging into an electric vehicle revolution
A road trial of plug-in hybrid electric vehicles (PHEVs), which could one day end up in every Australian driveway, is underway.   view more (2009-10-28)

URI nutritionist finds chewing gum can reduce calorie intake, increase energy expenditure
A nutrition professor at the University of Rhode Island studying the effects of chewing sugar-free gum on weight management has found that it can help to reduce calorie intake and increase energy expenditure.   view more (2009-10-28)

According to a thesis, diet and hydration of sportspeople improve during competition
The main goal of this research was to determine the composition of the ingestion of a group of volunteer skiers, participants in the XXX Andrés de Regil BBK Trophy Mountain Trek and correlate them with their anthropometric blood parameters, and with the time obtained in the trials.   view more (2009-10-26)

Single-stranded DNA-binding protein is dynamic, critical to DNA repair
Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth along single-stranded DNA, gradually allowing other proteins to repair, recombine or replicate the strands.   view more (2009-10-22)
