Studies might improve understanding of leading cause of mental retardation in girls By studying gene mutations in patients with the complex set of behavioral and neurological symptoms that accompany Rett syndrome, Howard Hughes Medical Institute investigator Huda Zoghbi and her colleagues at Baylor College of Medicine have designed a mouse model that faithfully recapitulates the disease down to its distinctive hand-wringing behavior. The development of the mouse, reported in the July

After 40 years of searching for the photoreceptor that controls multiple vital processes in fungi, researchers at UT Southwestern Medical Center at Dallas have discovered the protein that triggers this phenomenon.

Light regulates several physiological processes in fungi, including their ability to produce spores and the synchronization of their internal biological clocks, but their photoreceptors – receptors that are sensitive to light and are essential for most ongoing processes – were not

UC Berkeley scientist urges drilling into frozen lake under ice near South Pole as prelude to drilling into subglacial lakes in Antarctica and into Mars polar caps

Measurements of the ice temperature far below the South Pole suggest that a so-called “lake” discovered at the base of the ice is most likely permafrost – a frozen mixture of dirt and ice – because the temperature is too low for liquid water.
Far from being a disappointment, says a University of California, Berkeley p

Almost half of the first top 10 websites displayed by leading search engines on vaccination are emotive “anti” sites, finds a study in the Archives of Disease in Childhood. Many masquerade as official scientific sites, making it easier for users to be misinformed, say the authors.

The researchers keyed in the terms “vaccination” and “immunis(z)ation” into seven leading search engines: Google; Netscape; Altavista; GoTo; HotBot; Lycos; and Yahoo. They then used just the term “vaccination,” for

Highly promising results from clinical trials indicate that alpha-emitting radioisotopes can kill cancer cells. The Commission’s Joint Research Centre (JRC) and Deutsches Krebsforschungszentrum presented this innovative therapy during a recent workshop in Heidelberg. Alpha-immunotherapy should develop into an effective treatment over the next few years and provide new methods of healing for patients. How does the cancer-killing mechanism work? A cancer-cell selective vehicle, (e.g. a monocolonal anti

Machines not bigger than a molecule will one day surf our blood stream, search and destroy infected tissues, and heal our wounds. This is just one of the applications of nanotechnology. EU Research Commissioner Philippe Busquin will chair an information day on nanotech new frontiers in Grenoble, France, on 14 June 2002. Nanotech research is still in its start-up phase, and will be far more effective if co-ordinated and supported at EU level. The Commission will therefore allocate € 700 million to nan
