Planned Improvements Will Reduce Mixed Sex Accommodation Throughout Somerset's Community Hospitals, England
Hospital facilities upgrades due for completion by June 2009. Measures to reduce and eventually eliminate mixed sex wards and washing facilities throughout Somerset"s 13 community hospitals are nearing completion. Last year the government pledged to reduce mixed sex accommodation throughout all England"s NHS hospitals. All hospitals have now stepped up their efforts to deliver this goal.

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.
