Hyundai to Unveil Fuel Cell Electric Vehicle
September 1, 2007 01:16 PM - Paul Schaefer, ENN

SEOUL, South Korea - Hyundai Motor Corporation will unveil the i-Blue Fuel Cell Electric Vehicle at the 2007 Frankfurt International Motor Show on September 13. The all-new i-Blue platform is tailored to incorporate Hyundai's third-generation fuel cell technology, currently being developed at Hyundai's Eco-Technology Research Institute in Mabuk, Korea.

Scientists At MIT Unraveling The Secrets Of Red Tide
August 31, 2007 06:49 PM - Anne Trafton, MIT

Cambridge, Mass. - In work that could one day help prevent millions of dollars in economic losses for seaside communities, MIT chemists have demonstrated how tiny marine organisms likely produce the red tide toxin that periodically shuts down U.S. beaches and shellfish beds. In the Aug. 31 cover story of Science, the MIT team describes an elegant method for synthesizing the lethal components of red tides. The researchers believe their method approximates the synthesis used by algae, a reaction that chemists have tried for decades to replicate, without success.

Malaria Mosquito's Odour-Sensing Systems Mapped
August 31, 2007 04:57 PM - Michael Malakata, SciDevNet

Vanderbilt University - Scientists have mapped a sensory organ that the principal malaria-carrying mosquito, Anopheles gambiae, uses to hunt down humans. They hope this will help in developing better mosquito attractants that will divert them away from humans and reduce the threat of malaria infection.

Scientists have something to chew on:Ancient yucca chaws yield ancient DNA
August 31, 2007 02:06 PM - Harvard University Gazette

In a groundbreaking study, two Harvard scientists have for the first time extracted human DNA from ancient artifacts. The work potentially opens up a new universe of sources for ancient genetic material, which is used to map human migrations in prehistoric times. Before this, archaeologists could only get ancient DNA from relics of the human body itself, including prehistoric teeth, bones, fossilized feces, or — rarely — preserved flesh. Such sources of DNA are hard to find, poorly preserved, or unavailable because of cultural and legal barriers.

Star Trek Medical Device Uses Ultrasound Could Seal Punctured Lungs
August 31, 2007 10:53 AM - Hannah Hickey , Washington State University

SEATTLE - Engineers at the University of Washington are working with Harborview Medical Center doctors to create new emergency treatments right out of Star Trek: a tricorder type device using high-intensity focused ultrasound rays. This summer, researchers published the first experiment using ultrasound to seal punctured lungs.

New technique detects specific chromosomal damage, may indicate lung cancer risk
August 31, 2007 08:26 AM - American Thoracic Society

A new technique could pave the way toward screening people at risk for lung cancer for the genetic changes that may foreshadow malignancies, researchers from the University of Colorado say. “The most successful way to reduce mortality in cancer is prevention,” said researcher Wilbur A. Franklin, M.D., Professor of Pathology at the University of Colorado Health Sciences Center. “Our goal would be to develop screening techniques for lung lesions that could enable us to identify precancerous changes.”

The Clock Ticks On The Need For New Fuels: Volvo Demonstrates A Sampling Of Possibilities

On climate, on energy security, time is not on our side. Researchers at NOAA, the US National Oceanic and Atmospheric Administration, say that the record heat of 2006 was, in large part, caused by us. Researchers at NASA, the National Aeronautics and Space Administration, conclude in a article in Earth Observatory - “Greenland’s Ice Island Alarm” - that the island, eighty percent the size of the US east of the Mississippi, is losing significant amounts of ice. A side bar to the article says;

A Permanent Ban On Internet Taxes?
August 29, 2007 08:07 PM - Brian Wingfield, USC Law

WASHINGTON, D.C. - By all accounts, it's fairly safe to say that Congress is not going to allow state and local taxes on Internet service, at least for the next several years.

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
August 29, 2007 09:22 AM - Reuters

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.
