The National Science Foundation has awarded Williams College a $143,912 grant to equip a new laser facility, bringing together four research labs and a student workspace. The new equipment will enable researchers to measure optical wavelengths accurately and support a broad range of research in atomic, molecular, and optical physics.
Researchers found that a brief genetic response to heat stress can increase fruit fly lifespan at normal temperatures. The study reveals hsp70's role in moderating stress and potentially regulating aging.
The new guidelines, JNC VI, recommend stratifying patients into risk groups based on blood pressure stage and presence of risk factors. Lifestyle changes are advised for all patients on drug therapy, regardless of risk group.
Astronomers have detected the 'frame-dragging' effect, a prediction by Albert Einstein 80 years ago, in disks of gas swirling around black holes. The team used X-ray astronomy satellites to measure the precession of accretion disks, finding evidence of frame dragging in two black hole systems.
Researchers at St. Jude Children's Research Hospital have discovered a novel leukemia-producing transcription factor called E2A-HLF, which transforms immature lymphocytes by preventing normal destruction programs. This finding provides a potential window into understanding leukemias that result from altered survival signals.
The University of North Carolina at Chapel Hill School of Medicine is establishing a unique clinical trials unit to develop and test new therapies and vaccines for sexually transmitted diseases. The unit will focus on addressing major problems worldwide, including syphilis and gonorrhea, and will be the first of its kind in the US.
A new study found that vegetarian diets combined with vigorous exercise or moderate alcohol intake can significantly lower the risk of coronary artery disease. The research also showed that running and drinking were linked to increased levels of good cholesterol in both vegetarians and non-vegetarians.
Purdue University researchers isolate plant genes that enable efficient phosphate uptake, a key finding in addressing global phosphorus scarcity. The discovery may lead to the creation of more efficient phosphorus users and alternative sources of phosphorus.
