Results of a study by researchers at Dartmouth-Hitchcock Medical Center (DHMC) and Dartmouth Thayer School of Engineering could have implications for choosing which patients with abdominal aortic aneurysms should have surgery and which ones should simply have follow-up with noninvasive studies.
In an article published in the April issue of the Journal of Vascular Surgery, Dr. Mark Fillinger and colleagues describe a new noninvasive method for evaluating abdominal aortic aneurysms (AAA). Th
Scientists using NASA satellite data have found the most intense global pollution from fires occurred during droughts caused by El Niño. The most intense fires took place in 1997-1998 in association with the strongest El Niño event of the 20th century.
Bryan Duncan, Randall Martin, Amanda Staudt, Rosemarie Yevich and Jennifer Logan, from Harvard University, used data observed by NASA’s Total Ozone Mapping Spectrometer (TOMS) satellite to quantify the amount of smoke pollution from biomass b
Results from the ASCOT (Anglo Scandinavian Cardiac Outcome Trial) study have shown that patients receiving the cholesterol controlling drug, atorvastatin, are more than a third less likely to have heart attacks, and more than a quarter less likely to suffer from strokes.
The results of the study, announced today at the American College of Cardiology annual scientific session in Chicago, USA, and simultaneously published online in the Lancet, show that in a study of more than 10,305 people w
Scientists have been studying mutant plants that take an unusually long time to flower. At the SEB conference on Thursday 3 April, researchers from Horticulture Research International will present the results of their investigation into a RING finger protein (RING stands for Really Interesting New Gene) involved in regulating when a plant will flower.
Dr Stephen Jackson and colleagues have been working with mutants that have altered flowering times. One particular mutant that takes a long ti
The exotic island of Madagascar, situated off the southeast coast of Africa, was a dangerous place to live 65 million to 70 million years ago. Crocodiles swarmed in the rivers, and a 30-foot-long, meat-eating dinosaur named Majungatholus atopus stalked the plains. Like most carnivorous dinosaurs, Majungatholus had teeth perfectly suited for ripping into flesh. But what was on the menu? Until now, this question has remained a mystery. In a report published in the April 3 issue of the Journal
New physical phenomenon will likely impact atomic physics, chemistry and nanotechnology
In a discovery that is likely to impact fields as diverse as atomic physics, chemistry and nanotechnology, researchers have identified a new physical phenomenon, electrostatic rotation, that, in the absence of friction, leads to spin. Because the electric force is one of the fundamental forces of nature, this leap forward in understanding may help reveal how the smallest building blocks in nature r
