'Thin-layer' solar cells may bring cheaper 'green' power
Scientists are researching new ways of harnessing the sun's rays which could eventually make it cheaper for people to use solar energy to power their homes. view more (2007-08-24)
New evidence for dark energy in the universe
An international team of astronomers, led by scientists at the University of Manchester have produced new evidence that most of the energy in the Universe is in the form of the mysterious "Dark Energy". The new evidence comes from a 10-year census of the sky for examples of gravitational lenses, which are seen when a galaxy bends the light from a... view more... (2002-11-09)
A Common-sense Cure For Obesity (p 473)
In a Seminar in this week's issue of THE LANCET, Cara B Ebbeling and colleagues, from the USA, discuss the public-health crisis that is childhood obesity. Fat children, historically thought of as healthy, are now known to be at risk of many serious physiological and psychological complications. People who are obese are likely to die earlier than... view more... (2002-08-07)
University of Nevada professor demonstrates new hydrogen fuel system
Northern Nevada energy consumers can be excused if they have a sense of "sticker shock" when their power bills come due following the holiday season. Or, that they have a feeling of powerlessness as the price of gasoline climbs to $3 per gallon. view more (2007-02-23)
Biodiesel study targets cleaner air, cleaner engines
Cleaner engines, cleaner air and more uses for local farm products were the focus of a just-completed study of biodiesel as an alternative fuel source on selected Ontario farms. view more (2007-04-04)
New titanium manufacturing process saves energy, helps protect troops
Whether for stopping cars or bullets, titanium is the material of choice, but it has always been too expensive for all but the most specialized applications. view more (2008-05-21)
Methane bacteria possess pressure valve
Microbiologists from the University of Nijmegen have discovered that a methane-forming archaeabacterium sometimes deliberately allows hydrogen ions to leak out of its cell. At high hydrogen concentrations in particular, the cell membrane works as a sort of pressure valve. The waste of energy seems to be of vital importance for the microorganism.... view more...

More economical and easier to install wind generator: the wind reservoir
Two Basque companies, Enerlim and NECESA, have developed a new wind generator, a wind reservoir to make use of wind energy. This wind reservoir is much lighter than ordinary three-arm wind generators; hence, it is more economical and easier to install. On the other side, the machine is completely modular, as columns, pulleys and plates can be... view more... (2002-03-25)
Cancer cells 'reprogram' energy needs to grow and spread, study suggests
Studying a rare inherited syndrome, researchers at Johns Hopkins have found that cancer cells can reprogram themselves to turn down their own energy-making machinery and use less oxygen, and that these changes might help cancer cells survive and spread. view more (2007-05-08)
ESA finds a black-hole flywheel in the Milky Way
Far away among the stars, in the Ara constellation of the southern sky, a small black hole is whirling space around it. If you tried to stay still in its vicinity, you couldn`t. You`d be dragged around at high speed as if you were riding on a giant flywheel. In reality, gas falling into the black hole is whirled in that way. It radiates energy,... view more... (2002-04-26)
New source for biofuels discovered
A newly created microbe produces cellulose that can be turned into ethanol and other biofuels, report scientists from The University of Texas at Austin who say the microbe could provide a significant portion of the nation's transportation fuel if production can be scaled up. view more (2008-04-24)
Durham University leads UK research project into cheaper solar energy
A national team of scientists led by experts at Durham University are embarking on one of the UK's largest ever research projects into photovoltaic (PV) solar energy. view more (2008-01-15)
National Academies news: Emissions-free, petroleum-free vehicles
A public-private effort to develop more fuel-efficient automobiles and eventually introduce hydrogen as a transportation fuel is well-planned and identifies all major hurdles the program will face, says a new report from the National Academies' National Research Council. view more (2005-08-03)
Air-conditioning of buildings using solar energy
2% of buildings capable of having solar air-conditioning installed, could stop emitting 27,000 tons of CO2 into the atmosphere view more (2003-01-16)
Pitt researchers create new form of matter
Physicists at the University of Pittsburgh have demonstrated a new form of matter that melds the characteristics of lasers with those of the world's best electrical conductors. view more (2007-05-21)
Light from wind and waves
Engineers of PROEKTSTROYSERVIS (Kaliningrad) know how to make the stormy sea work. They have designed a unique sea-based wind-and-wave plant, which allows to convert the energy of wind and waves into electricity. The plant is not afraid of any storms. In appearance, the entire construction is reminiscent of a float, UFO or the restaurant in the... view more... (2003-08-22)
Algae could one day be major hydrogen fuel source
As gas prices continue to soar to record highs, motorists are crying out for an alternative that won't cramp their pocketbooks. view more (2008-04-02)
Reactor upgrades help researchers study nuclear fusion as energy source
For about six months of the year, bursts of a hot, electrically charged gas, or plasma, swirl around a donut-shaped tube in a special MIT reactor, helping scientists learn more about a potential future energy source: nuclear fusion. view more (2007-02-14)
World-first technology enables study of ancient bacteria
Experts at Cardiff University, UK, have designed world-first technology to investigate sustainable energy sources from the ocean bed by isolating ancient high-pressure bacteria from deep sediments. view more (2005-06-06)
High-value chemicals produced from ethanol feedstocks could boost biorefinery economics
Biorefineries developed to produce ethanol from cellulose sources such as trees and fast-growing plants could get a significant economic boost from the sale of high-value chemicals - such as vanillin flavoring - that could be generated from the same feedstock. view more (2006-09-11)
