Galician waves are best for producing energy
The best coastal areas in the Iberian Peninsula in terms of harnessing wave energy are the Costa da Morte and Estaca de Bares, in La Coruña, Galicia, according to two pioneering studies by researchers from the University of Santiago de Compostela (USC), published this month in the journals Energy and Renewable Energy. view more (2009-11-30)
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)
ESA spacecraft may help unravel cosmic mystery
When Europe's comet chaser Rosetta swings by Earth tomorrow for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades. view more (2009-11-13)
New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system. view more (2009-11-13)
Sponges recycle carbon to give life to coral reefs

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'
