New Standard For Sustainable Carpets
November 12, 2007 07:05 PM - Glenn Hasek, Green Lodging News
CHICAGO—Architects, designers and end users will now have one Standard to identify carpets that have a reduced environmental impact. The first multi-attribute American National Standards Institute (ANSI)-approved Standard—NSF 140-2007, Sustainable Carpet Assessment Standard for environmentally preferable building materials—was introduced at Greenbuild 2007.
The unified Standard for sustainable carpet is voluntary, inclusive, based on life cycle assessment (LCA) principles, and offers three levels of achievement for attaining various levels of reduced environmental impact (silver, gold and platinum). By defining environmental, social and economic performance requirements, the Standard provides benchmarks for continual improvement and innovation within the building industry.
Pump price to jump 20 cents next 2-3 weeks: government
November 12, 2007 06:39 PM - By Tom Doggett
WASHINGTON (Reuters) - U.S. consumers could pay record gasoline prices for the upcoming Thanksgiving holiday with pump costs expected to climb another 20 cents over the next two to three weeks, the government's top energy forecaster warned on Monday.
Guy Caruso, who heads the U.S. Energy Information Administration, said not all of the recent jump in crude oil prices has been reflected in motor fuel costs which now top $3 a gallon in many parts of the country, about 80 cents more than a year ago.
"We haven't seen the full pass-through (of high oil prices) yet," Caruso told reporters at a briefing on oil market conditions held at Energy Department headquarters. "I would say what's in the pipe right now (for gasoline) is about another 20 cents."
New technique to treat varicose veins
November 12, 2007 12:43 PM - Rachel Champeau
Los Angeles - Dr. Peter Lawrence, UCLA's chief of vascular surgery, picks up size 7 crochet hooks from a fabric store — not to make sweaters or scarves but to use in a new technique he has developed to treat varicose veins.
Early results of the new outpatient procedure, called light-assisted stab phlebectomy, or LASP, appear in a study in the October issue of the journal The American Surgeon. More than 250 patients at UCLA have undergone Lawrence's procedure, which is designed to remove branch varicose veins from the thighs, calves and ankles.
Drug injecting triggers most Mauritius HIV cases
November 12, 2007 12:35 PM -
ROCHE BOIS, Mauritius (Reuters) - Drug abuse accounts for 92 percent of new HIV infections in Mauritius, up from just 14 percent in 2002, the government said on Monday.
The Indian Ocean island nation has an estimated HIV prevalence rate of 1.8 percent, which is low for the region. On the African mainland, HIV infection rates stand at 16.1 percent in Mozambique and 18.8 percent in South Africa, for example.
But officials say risky practices like sharing needles used for injecting drugs are causing many more infections. Mauritius suffers the second highest rate of heroin and opiate use in the world, according to U.N. figures.

Make Way for the Real Nanopod

BERKELEY, CA — Make way for the real nanopod and make room in the Guinness World Records. A team of researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have created the first fully functional radio from a single carbon nanotube, which makes it by several orders of magnitude the smallest radio ever made.
Diesel- and Hybrid-Powered Vehicles Can Provide More Societal Benefits than Gas-Powered Autos
November 12, 2007 08:46 AM - RAND Corp
Cars and light trucks powered by advanced diesel technology or hybrid technology can provide larger societal benefits than traditional gasoline-powered automobiles, according to a RAND Corporation working paper presented today.
The research by RAND, a non-profit research organization, also found that light trucks and cars continuously fueled by a mixture of 85 percent ethanol and 15 percent gasoline – known as E85 – compare unfavorably with the other two alternatives.
Prehistoric women had passion for fashion
November 12, 2007 08:22 AM - Ljilja Cvekic
If the figurines found in an ancient European settlement are any guide, women have been dressing to impress for at least 7,500 years.
Recent excavations at the site -- part of the Vinca culture which was Europe's biggest prehistoric civilization -- point to a metropolis with a great degree of sophistication and a taste for art and fashion, archaeologists say.
J-PAL course in Nigeria promotes science-based approach in poverty fight
November 11, 2007 10:37 PM -
MIT's Abdul Latif Jameel Poverty Action Lab (J-PAL) is technically located in Building E60 on the edge of east campus. But J-PAL's real laboratory is a primary school in a sub-Saharan African town, a household kitchen in a home in rural India, an unemployment line in a suburb of Paris-anywhere antipoverty programs are necessary to improve a population's health and well-being.
J-PAL is dedicated to fighting poverty by ensuring that policy decisions are based on scientific evidence. As part of that effort, J-PAL undertakes, promotes the use of and disseminates the results of randomized evaluations of poverty-alleviating programs.
HIV Vaccine Target Could Solve Mutation Problem
November 11, 2007 10:17 PM - UC Newswire
Researchers at UCSF and the University of Toronto have identified a potential new way of fighting against HIV infection that relies on the remnants of ancient viruses, human endogenous retroviruses (HERV), which have become part of the genome of every human cell.
Mounting evidence suggests that HIV infection could enable HERV expression by disrupting the normal controls that keep HERV in check. In some HIV-infected individuals, infection fighting T-cells are able to target HERV expressing cells.
Researchers believe that their findings, published in the Nov. 9, 2007 issue of the journal PLoS Pathogens, could lead to a vaccine targeting HERV that kills HIV-infected cells.
