Pulselike and Cracklike Ruptures in Earthquake Experiments
December 5, 2007 11:10 AM -
Pasadena, California - Lab experiments that mimic the way the ground moves during destructive earthquakes require some sophisticated equipment, and they yield valuable insights. Caltech scientists studying how sliding motion spreads along a fault interface conducted a series of experiments involving ultrafast digital cameras and high-speed laser velocimeters to replicate a range of realistic fault conditions.
EPA Urged To Cut Pollution From Aircraft
December 5, 2007 10:25 AM -
Washington, DC – A coalition of state governments, including California, cities, regional governments and environmental groups filed petitions with the U.S. Environmental Protection Agency today urging the agency to address the effects of vast amounts of global warming pollution from the world’s aircraft fleet.
The petitions are the first step in a process that requires the EPA to evaluate the current impacts of aircraft emissions, seek public comment and develop rules to reduce aircraft emissions or explain why it will not act.

NEW DELHI - Human trials of a US-produced HIV/AIDS vaccine were halted in India last month (November) after it was found to induce poor immune responses.
The vaccine, developed by the US-based Targeted Genetics Corporation, uses the adeno-associated virus (AAV) as a vector to deliver an AIDS vaccine against subtype C, the dominant HIV subtype in India.
India's National AIDS Research Institute (NARI) tested the vaccine on 30 volunteers.
New Fuel Cell: Using Pollution to create energy
December 4, 2007 09:55 AM - American Chemical Society
Scientists in Pennsylvania are reporting development of a fuel cell that uses pollution from coal and metal mines to generate electricity, solving a serious environmental problem while providing a new source of energy. They describe successful tests of a laboratory-scale version of the device in a new study.
Online activism may make the difference on Election Day
December 3, 2007 03:13 PM - Peter Lewis, University of Washington
Seattle - More and more, Congressional candidates are turning to the Web as a tool to mobilize their base and build credibility with undecided voters, according to findings in a new book by a University of Washington researcher.
"We're seeing a slow-but-steady increase in Web mobilizing," particularly in competitive House and Senate races, said Kirsten Foot, an associate professor of communication.
FDA faces damning report on science expertise
December 3, 2007 02:11 PM - Kim Dixon, Reuters
WASHINGTON (Reuters) - Lives are at risk because the U.S. Food and Drug Administration is woefully behind in the latest scientific advances and is underfunded for its vast responsibilities, an expert panel will tell the FDA on Monday.
In a 56-page report titled "FDA Science and Mission at Risk," which has been posted online, officials will hear that inadequate staffing and poor retention, out-of-date technology and a general lack of resources mar the agency's ability to do its job.
Greenest Condo in the U.S. Opens in Portland
December 3, 2007 11:57 AM - Paul Schaefer, ENN
PORTLAND - Residents began this week moving into The Casey condominiums, on track to be the first multifamily residential building in the United States to receive LEED Platinum certification, the highest level of green building.
The Casey is a 16-story building with 61 luxury homes in the heart of Portland's Pearl District, steps from art galleries, restaurants and boutiques. The building incorporates a comprehensive array of sustainable features including solar panels, a green roof and the extensive use of recycled-content and sustainable materials such as wool carpets and FSC-certified wood flooring. It also has a host of energy efficiency features including sophisticated waste heat recovery ventilators in each unit that help the building achieve a 52 percent energy savings over code.
Exercise may boost brain's natural antidepressant
December 3, 2007 10:41 AM - Amy Norton, Reuters
NEW YORK (Reuters Health) - Exercise seems to increase the production of naturally occurring brain chemical with antidepressant effects in mice, researchers reported Sunday.
The findings, published in the journal Nature Medicine, point to potential new ways to treat depression in people.
Studies have found that exercise can help ease depression symptoms, but the reasons for the benefit have not been clear. For the new study, scientists used a tool called a microarray to examine how exercise changed gene activity in the brains of mice.
