Study suggests promising new insights for men with early-stage disease

A fat-laden diet and high calcium consumption are both well-known suspected risk factors for prostate cancer. However, new findings from the Fred Hutchinson Cancer Research Center suggest that fat and calcium themselves may not cause prostate cancer, as previously thought, but instead may fuel its progression from localized to advanced disease.

While high intake of dietary fat and calcium is associated wi

Dartmouth Medical School geneticists have found a molecular shortcut from light reception to gene activation in their work to understand biological clocks. Their research has revealed that the protein called White Collar-1 does double duty: it perceives light and then, in response to light, directly turns on a key gene called frequency, which is a central component of the clock.

Biological clocks are molecularly driven and are set, or synchronized, by the daily cycles of light and dark. Usin

Cornell University potato breeders are donating a disease-resistant potato to Russia in an effort to help combat aggressive strains of potato late blight that are threatening to devastate the nation’s essential small farms.

The Cornell-developed New York 121 potato, which also is able to fend off golden nematodes, scab and potato virus Y (PVY), will be given to Dokagene Technologies, a company specializing in producing pathogen-free seed in Russia, in a meeting and a field trip in Mosc

The overuse of antibiotics not only leads to more resistant strains of infection, but, according to new research from the University of Wisconsin-Madison, antibiotics also may be adversely affecting zooplankton, tiny organisms that underpin the health of all freshwater ecosystems.

In the last decade, European and American researchers have found more evidence that lakes and streams are tainted by common drugs, ranging from caffeine to anticancer agents.

This pollution, says Colleen

Rich and Inspiring Experience with NGC 300 Images from the ESO Science Data Archive
A series of wide-field images centred on the nearby spiral galaxy NGC 300, obtained with the Wide-Field Imager (WFI) on the MPG/ESO 2.2-m telescope at the La Silla Observatory, have been combined into a magnificent colour photo.

These images have been used by different groups of astronomers for various kinds of scientific investigations, ranging from individual stars and nebulae in NGC 300, to distant gal

A study team led by experts at the University of Southampton has found that there is no significant risk to the public from radioactive contamination from the Atomic Weapons Establishments at Aldermaston and Burghfield in West Berkshire.

The three-year environmental radioactivity project, carried out by the University’s Geosciences Advisory Unit at the Southampton Oceanography Centre, examined over 600 soil and other samples from a wide variety of locations and environments.
