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
August 30, 2007 11:53 AM - Bruce Mulliken, Private Landowner Network
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.
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 ORNLļæ½s 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.
