NASA Satellites Eye Coastal Water Quality
August 29, 2007 10:26 AM - University of South Florida
GREENBELT, Md. - Researchers armed with data from two NASA satellites have invented a way to map the fleeting changes in coastal water quality from space. The task long had evaded researchers and coastal managers relying only on ground-based data. Using data from instruments aboard NASA satellites, researchers at the University of South Florida found that they can monitor water quality almost daily, rather than monthly. This has direct value to resource managers tasked with creating restoration plans for coastal water ecosystems, and federal and state regulators in charge of setting water quality standards.
Volvo unveils green engines for trucks

Sweden's Volvo, the world's second biggest truck maker, unveiled on Wednesday a line of truck engines adapted to run on renewable fuels and called for more efforts to make such fuels commercially available. The engines are powered by seven types of fuel, ranging from synthetic diesel to a mix of hydrogen and biogas. These are made from renewable raw materials and do not add carbon dioxide to the ecosystem, the company said.
Now It's Not Just Spiderman That Can Scale The Empire State Building
August 29, 2007 08:59 AM - Insitutue of Physics
Physicists have found the formula for a Spiderman suit. Only recently has man come to understand how spiders and geckos effortlessly scuttle up walls and hang from ceilings but it was doubted that this natural form of adhesion would ever be strong enough to hold the weight of real life Peter Parkers.
Isuzu and Toyota Reach Basic Agreement on Small Diesel Engines
August 29, 2007 08:25 AM - , Green Progress
Isuzu Motors Limited (Isuzu) and Toyota Motor Corporation (TMC) announced today that they have reached a basic agreement concerning a business collaboration on the development, production and supply of small diesel engines. Isuzu and TMC signed a memorandum of understanding last November to begin studying the synergic effects of business collaboration to mutually utilize their management resources in the fields of R&D and production, and to supplement each other's technological development. Since then, the two companies have conducted investigations with the aim of reaching agreement on the specific details of the business collaboration.
New roof technology could save you money
August 29, 2007 07:04 AM - DOE/Oak Ridge National Laboratory
From an energy efficiency perspective, roof technology has not progressed substantially in hundreds of years, but that is changing with the use of active thermal mass components, reflective pigments and coatings, subventing, radiant barriers and other novel techniques being tested by a team led by Bill Miller and Jan Kosny of ORNL�s Building Envelopes group. Their prototype roof and attic system works by reducing attic temperatures by about 22 degrees Fahrenheit during a typical summer afternoon and decreasing the amount of heat that gets transferred through the attic floor to the living space.

Jatropha Curcas: Promising Biofuel Feedstock Or Invasive Species?
August 28, 2007 07:27 PM - Bruce Mulliken, Private Landowner Network
Generally speaking, transplanting a species from one part of the world to another - either accidentally or on purpose - has, on occasion, had some really negative consequences. A prime example is kudzu that was moved from Asia to the southeast US beginning in the 1930’s to control erosion. It did that but now kudzu overgrows just about everything in its path and is almost impossible to get rid of. Now, with the push to find alternative and renewable sources of fuel in the US and elsewhere, oil from the seeds from a shrub called Jatropha Curcas has arisen as a very good source of biodiesel.

Europe Wants To Turn Wine Into Biofuel
August 28, 2007 06:30 PM - Reuters
BRUSSELS - The European Union has opened a tender to sell unwanted wine in four countries for use in making bioethanol, its Official Journal said on Tuesday. The tender would offer roughly 693,376 hectoliters of wine alcohol stored in France, Greece, Italy and Spain. The deadline for bids was September 10, it said in its latest edition. France, the world's largest wine producer, would offer 239,995 hectoliters of wine alcohol for distillation, while Italy and Spain would offer 200,000 hectoliters apiece. The balance of roughly 53,381 hectoliters will come from Greece.
Bacteria Sense Light, Use It To Regulate Virulence
August 28, 2007 04:39 PM - UC Santa Cruz
University of California, Santa Cruz - The bacteria that cause brucellosis can sense light and use the information to regulate their virulence, according to a study in the August 24 issue of the journal Science. The discovery comes after 120 years of research into the disease, which causes abortions in livestock and fevers in humans. Researchers found that two other bacteria, including a species that attacks plants, sense light using the same type of protein structure, and at least 94 more species possess the code for it in their DNA.
