E.P.A. Vows Better Effort on WaterThe E.P.A. administrator said the agency was "falling short of this administration's expectations" for the effectiveness of clean water enforcement.
New York Times Friday, October 16, 2009Radiation Overdoses Point Up Dangers of Misused CT ScansAt a time when Americans receive far more diagnostic radiation than ever before, the cases underscore the risks posed by a diagnostic tool when used incorrectly.
International Herald Tribune Friday, October 16, 2009Las Gaviotas Journal: An Isolated Village Finds the Energy to Keep GoingVisitors to a remote village in Colombia can get a glimpse into a four-decade experiment to alter civilization's dependence on finite fossil fuels and industrial agriculture.

New York Times Friday, October 16, 2009New Software Could Smooth Supercomputing Speed BumpsSupercomputers have long been an indispensable, albeit expensive, tool for researchers who need to make sense of vast amounts of data. One way that researchers have begun to make high-speed computing more powerful and also more affordable is to build systems that split up workloads among fast, highly parallel graphics processing units (GPUs) and general-purpose central processing units (CPUs).

Scientific American Friday, October 16, 2009How to Get More Bicyclists on the RoadGetting people out of cars and onto bicycles, a much more sustainable form of transportation, has long vexed environmentally conscious city planners. Although bike lanes painted on streets and automobile-free “greenways” have increased ridership over the past few years, the share of people relying on bikes for transportation is still less than 2 percent, based on various studies. An emerging body of research suggests that a superior strategy to increase pedal pushing could be had by asking the perennial question: What do women want?In the U.S., men’s cycling trips surpass women’s by at least 2:1. This ratio stands in marked contrast to cycling in European countries, where urban biking is a way of life and draws about as many women as men--sometimes more. In the Netherlands, where 27 percent of all trips are made by bike, 55 percent of all riders are women. In Germany 12 percent of all trips are on bikes, 49 percent of which are made by women. [More]
Scientific American Friday, October 16, 2009TraDIS technique tackles typhoidFor the first time, researchers have looked at the need for every gene in a bacterial cell in just one experiment. They showed that Salmonella Typhi -- which every year infects 22 million people and causes 220,000 deaths -- needs only 356 genes for survival: 4162 genes are not essential. The method, which harnesses next-generation sequencing technologies, will aid the search for weaknesses in bacterial armories, allowing researchers to seek treatments to target those genes.
Eurekalert.org Friday, October 16, 2009Trial raises doubts over alternative pain therapy for arthritisCopper bracelets and magnetic wrist straps are ineffective in relieving arthritis pain, according to a new study led by a University of York academic.
Eurekalert.org Friday, October 16, 2009A case of post-gastrectomy acute pancreatitisA clinical research team from Taiwan reported a case of asymptomatic pancreatic divisum who underwent palliative subtotal gastrectomy for an advanced gastric cancer with liver metastasis. They concluded for patients with pancreas divisum or dominant duct of Santorini who fail to follow the normal post-operative course after gastrectomy, clinicians should be alert to the possibility of post-gastrectomy acute pancreatitis as one of the potential diagnoses.
