Yale Researchers Find Tools Needed To Build A Cellular Shredder
Yale University researchers have discovered a set of cellular chaperones needed to assemble a proteasome, the cellular workhorse that recycles proteins and is crucial for the existence of all eukaryotic cells.

The US National Heart, Lung, And Blood Institute Battles Chronic Disease In Developing Countries
The US National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, which is a founding member of the Global Alliance for Chronic Disease, has decided to go forward strongly and improve its plan to target chronic diseases in developing countries by collaborating with a leading health and wellbeing corporation. Together, they plan to build numerous centers of excellence (COEs) across the world. The details of this partnership have been published in a comment Online First and in this week"s edition of The Lancet.

New Study Indicates Radiologists Need Standards To Ensure Optimal Visual Accuracy
Radiologists, like professional pilots for example, depend on good vision as part of their occupation. However, radiologists unlike pilots are not required to undergo regular vision testing. A new study found that approximately 50% of radiologists surveyed indicated they don"t recall ever having their vision tested or it had been 24 months or longer since their last vision exam.

New Insights Into Health And Environmental Effects Of Carbon Nanoparticles

A new study raises the possibility that flies and other insects that encounter nanomaterial "hot spots," or spills, near manufacturing facilities in the future could pick up and transport nanoparticles on their bodies, transferring the particles to other flies or habitats in the environment. The study on carbon nanoparticles - barely 1/5,000th the width of a human hair - is scheduled for the Aug. 15 issue of ACS" Environmental Science & Technology, a semi-monthly journal. David Rand and Robert Hurt and colleagues note that emergence of a nanotechnology industry is raising concerns about the potential adverse health and environmental effects of nanoparticles. These materials show promise for use in a wide range of products, including cosmetics, pharmaceuticals, and electronics. The study focused on determining how different kinds of exposure to nanoparticles affected larval and adult fruit flies. Scientists use fruit flies as stand-ins for humans and other animals in certain kinds of research. There were no apparent ill effects on fruit fly larvae that ate food containing high concentrations of nanoparticles. However, adult flies died or were incapacitated when their bodies were exposed to large amounts of certain nanoparticles. During the experiments, the researchers noted that contaminated flies transferred nanoparticles to other flies, and realized that such transfer could also occur between flies and humans in the future. The transfer involved very low levels of nanoparticles, which did not have adverse effects on the fruit flies. Since larvae can tolerate very high doses of nanoparticles in the diet, but adult flies show very different sensitivities, the environmental impact depends on the ecological context of nanoparticle release.
