These lasers represent the world's highest-energy laser system

Although it would probably first be used in a clinical setting, our vision is to have a self-administered flu vaccine patch. So instead of making an appointment with your doctor to get your flu shot, you can stop by the pharmacy or even get a patch in the mail and self-apply," Prausnitz explains.

Prausnitz, Ph.D. School of Chemical Biomolecular Engineering Georgia Institute of Technology Atlanta, Ga. 30332-0100 Toward limitless energy: National Ignition Facility focus of symposium EMBARGOED FOR RELEASE: Wednesday, Aug. 19, 9 a.m., Eastern TimeChemists are preparing to play an important but often unheralded role in determining the success of one of the largest and most important scientific experiments in history — next year's initial attempts at the National Ignition Facility (NIF) to produce the world's first controlled nuclear fusion reaction. If successful in taming the energy source of the sun, stars, and of the hydrogen bomb, scientists could develop a limitless new source of producing electricity for homes, factories, and businesses. The experiment could also lead to new insights into the origins of the universe. A special two-day symposium addressing this topic, "Nuclear Diagnostics in Fusion Energy Research," will be presented Aug. 19 and 20 during the 238th National Meeting of the American Chemical Society (ACS).Scientists have been trying to achieve controlled nuclear fusion for almost 50 years. In 2010, researchers at the NIF at Lawrence Livermore National Laboratory in California will focus the energy of 192 giant laser beams onto a pea-sized target filled with hydrogen fuel. These lasers represent the world's highest-energy laser system. The scientists hope that their effort will ignite, or fuse, the hydrogen atoms' nuclei to trigger the high energy reaction."Chemists will definitely play a role in determining whether nuclear fusion reactions have occurred during Rosetta Stone this NIF experiment, which is key to determining whether the experiment is a success," says Dawn Shaughnessy, Ph.D., a scientist with Lawrence Livermore National Laboratory."The idea is that the lasers will fuse hydrogen particles together, producing neutrons," says Shaughnessy, one of many scientists who plan to analyze materials produced by the reaction. "We'll collect and measure the materials produced from the ignition and hopefully be able to determine how many neutrons were made. More neutrons mean that more fusion has occurred."ARTICLE #2 EMBARGOED FOR RELEASE: Wednesday, Aug. 19, 9 a.m., Eastern TimeFor full-text of the press release, click here.

But scientists are reporting some unsettling news about homes in the residential areas of California. The typical house there — and probably elsewhere in the country — is an alarming and probably underestimated source of water pollution, according to a new study reported today at the 238th National Meeting of the American Chemical Society.In the study, Lorence Oki, Darren Haver and colleagues explain that runoff results from rainfall and watering of lawns and gardens, which winds up in municipal storm drains. The runoff washes fertilizers, pesticides and other contaminants into storm drains, and they eventually appear in rivers, lakes and other bodies of water. "Results from our sampling and monitoring study revealed high detection frequencies of pollutants such as pesticides and pathogen indicators at all sites," Oki says of their study of eight residential areas in Sacramento and Orange Counties in California. Preliminary results of the study suggest that current models may underestimate the amount of pollution contributed by homes by up to 50 percent.
