Biofuels 'are not a magic bullet'
Biofuels may play a role in curbing climate change, says Britain's Royal Society, but may create environmental problems unless implemented with care.

Body Heat To Power Cell Phones? Nanowires Enable Recovery Of Waste Heat Energy
Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) at Berkeley.

Experimental Weight-loss Drug Cuts Appetite, Burns More Energy
The first clinical studies of an experimental drug have revealed that obese people who take it for 12 weeks lose weight, even at very low doses. Short-term studies also suggest that the drug, called taranabant--the second drug designed to fight obesity by blocking cannabinoid receptors in the brain -- seems to cause people to consume fewer calories and burn more.

Prairie grass energy boost studied in the field
Switchgrass, a prairie grass that sways around the borders of many US fields, offers 540% more energy than the energy sown into it, research has shown. The renewable fuel should be seriously considered as a low-greenhouse-gas, high-energy biofuel source, the researchers say.

Climate worries complicate Alaska drilling plan
A controversial proposal to extract vast supplies of oil and gas from Alaska's outer continental shelf pits America's energy needs against environmental protection. Unlike similar clashes in the past, there's a complicating factor this time: global warming.

Surprise: That Interstellar Disco Ball Is Still Sparkling
A joint Japanese-American research team has found an odd beastie in deep space – a white dwarf expected to be as dead as an interstellar doornail, but which in fact is giving off powerful pulsar-like energy.

Scientists highlight environmental impacts of biofuels
Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production. Corn, soy and sugarcane come up short.

U.S. Wavers Again on ITER
The countries planning the world's biggest fusion experiment have learned not to count on the United States. So this week's decision by the U.S. Congress to strip out a planned $149 million contribution in 2008 to the International Thermonuclear Experimental Reactor (ITER) won't halt next year's planned start of the project

A portable system converts biowaste into jet fuel and diesel for the military
Last year, the U.S. military used more than five billion gallons of petroleum-based fuels. Transporting the fuel to battle zones and remote military bases is costly and time consuming, and the fuel is a prime target of terrorists. So the U.S. Department of Defense is looking for cheaper, more secure, and easier options.

New Energy Law In, Renewable Energy Left Out
As we've covered, the Energy Bill signed into law this morning by President Bush is not a comprehensive answer to the United States' energy problems. But hey, maybe that's too much to ask from one piece of legislation that has to be hammered out in the Senate.

Turning Carbon Dioxide into Fuel
Could concentrated solar energy be used to reverse combustion and convert carbon dioxide back into gasoline? That's what scientists at Sandia National Laboratories, in Albuquerque, NM, aim to find out by building a novel reactor that can chemically "reenergize" carbon dioxide.
