NIEHS Launches Website With Information For Assessing Environmental Ha
A new website with a Global Information System will provide valuable information for assessing environmental hazards caused by Hurricane Katrina. The National Institute of Environmental Health Sciences (NIEHS), one of the National Institutes of Health, created the website to provide the most up-to-date data to public health and safety workers on contaminants in flood waters, infrastructure and industry maps, as well as demographic information for local populations. Echoes Of The Birth Of The Universe: New Limits On Big Bang's Gravitat
An investigation by the LIGO Scientific Collaboration and the Virgo Collaboration has significantly advanced our understanding the early evolution of the universe. Analysis of data taken from 2005 to 2007 has set the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where LIGO can observe. The data put new constraints on the details of how the universe looked in its earliest moments. Engineers Build DNA 'Nanotowers' With Enzyme Tools
Duke engineers have added a new construction tool to their bio-nanofabrication toolbox. Using an enzyme called TdTase, engineers can vertically extend short DNA chains attached to nanometer-sized gold plates. This advance adds new capability to the field of bio-nanomanufacturing. MRSA on the rise in hospital outpatients, new study finds; Seven-fold
The community-associated strain of the deadly superbug MRSA -- an infection-causing bacteria resistant to most common antibiotics -- poses a far greater health threat than previously known and is making its way into hospitals, according to a new study. Peter Gabriel Backs the Filter
The pop star swears by a free iTunes plug-in that can help create playlists centered on any song, but results are mixed. In Listening Post. Researchers To Improve Prostate Cancer Diagnostic Methods
Pioneering research to increase the accuracy of prostate cancer diagnoses has earned Rutgers University and its collaborators at the University of Pennsylvania $822,000 in research grants. The methods being developed use powerful high resolution MRI and computer-aided diagnosis techniques to reveal previously hidden cancerous tissue in prostate glands. Creeping Crinoids! Sea Lilies Crawl To Escape Predators, New Video Sho
With their long stalks and feathery arms, marine animals known as sea lilies look a lot like their garden-variety namesakes. Perhaps because of that resemblance, scientists had always assumed that sea lilies stayed rooted instead of moving around like their stalkless relatives, the feather stars. Be Kind RewindDirector Michel Gondry Forgoes Dreamy Plots
Michel Gondry is famous for making films with backward plots and gauzy sequences. His new work, about two video-store clerks who remake famous movies, is a straight-up narrative with crowd-pleasing Jack Black pratfalls. But don't worry — Gondry's still messing with Hollywood. Novel Gene Alterations Identified In Lung Cancer
Unprecedented study of the genomic landscape of lung cancer identifies key gene alteration not previously implicated in any form of cancer. The study also revealed more than 50 genomic regions that are frequently gained or lost in lung adenocarcinoma, the most common type of lung cancer in the United States. Risk Of Venuous Thrombosis In Long-haul Flights
Scientists provide the first absolute estimate of risk of venous thrombosis after air travel. Venous thrombosis has been linked to air travel since 1951 but despite a number of previous studies the absolute risk of symptomatic venous thrombosis after long-haul travel has not previously been calculated. The risk was particularly high in employees under age 30 years, women who used oral contraceptives, and individuals who were particularly short, tall, or overweight.
