Make Way for the Real Nanopod
November 12, 2007 09:08 AM - Berkely Lab
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.
Drug-resistant bacteria found to trick immune system
November 11, 2007 10:06 PM - Reuters
WASHINGTON (Reuters) - Drug-resistant bacteria called methicillin-resistant Staphylococcus aureus, or MRSA, may be able to first lure and then destroy immune system cells when they are the most vulnerable, researchers said on Sunday.
The study may help explain why MRSA spread outside of hospitals are harder to fight and seem to be spreading more easily.
But the findings may also lead to new and better antibiotics to fight the bacteria, the researchers reported in the journal Nature Medicine.
Rich urged to bear climate change costs
November 11, 2007 09:57 PM - By Jeremy Lovell, Reuters
LONDON (Reuters) - The rich caused the problem and must therefore pay the price of fixing the global climate change crisis, a new report said on Monday.
Christian Aid, an agency of British and Irish churches, said industrialized nations were historically responsible and therefore morally liable to foot the multi-billion dollar cost of tackling the problem of man-made emissions of carbon gases.
"Nations that have grown rich in part by polluting without facing the costs of doing so must now repay their carbon debt to the developing world," said Andrew Pendleton, author of "Truly Inconvenient - tackling poverty and climate change at once."
Remnant of Yellowstone volcano rising: study
November 10, 2007 06:49 PM - Reuters
WASHINGTON (Reuters) - A big blob of molten rock appears to be pushing up remnants of an ancient volcano in Yellowstone National Park in Wyoming, scientists reported on Friday.
They say no volcanic explosion is imminent -- that already happened 642,000 years ago, creating the volcanic crater known as a caldera where part of Yellowstone Lake sits.
But satellite readings show just how volcanically active the area remains, the researchers reported in the journal Science.
Click a mouse, feed a mouth in U.N. campaign
November 10, 2007 06:14 PM - Reuters
LONDON (Reuters) - A food-linked word game put on the Internet a month ago has proved a runaway success and has already generated enough rice to feed 50,000 people, the United Nations World Food Programme said on Friday.
FreeRice offers participants multiple choice definitions to the meaning of a word, with each correct click generating 10 grains of rice for the WFP.
The brainchild of American online fundraising pioneer John Breen, the Web site (www.freerice.com) relies on advertising revenue to underwrite its rice campaign.
