New genome sequence information from the humble baker's yeast has revealed surprising variation in a set of genes that can be thought of as nature's oldest clock. In a paper published in Genome Research scientists show how ribosomal RNA genes that are essential to all Earth's organisms provide insight into how genomes maintain their integrity on their evolutionary journey.
Scientists have designed tiny new sensor structures that could be used in novel security devices to detect poisons and explosives, or in highly sensitive medical sensors, according to research published tomorrow (8 April) in Nano Letters.
LEXINGTON, Ky. (April 6, 2009) - The side effects of an experimental "gene-silencing" treatment that is currently being investigated for a variety of diseases are even more wide-ranging than previously discovered, according to a study by a University of Kentucky researcher.

Dental amalgam has been proven safe and effective for years, yet unfounded controversy still surrounds it, a Medical College of Georgia researcher says.
DURHAM, N.C. - Duke University researchers have identified a receptor on the surface of cells that may give them another avenue of attack against glioblastoma, the most common and most deadly type of brain cancer.
AUSTIN, Texas-Banishing a fear-inducing memory might be a matter of the right timing, according to new research.
Marie Monfils, an assistant professor of psychology at The University of Texas at Austin, has taken advantage of a key time when memories are ripe for change to substantially modify memories of fear into benign memories and to keep them that way.
Seattle - A study showing improved survival of starting antiretroviral treatment earlier than current U.S. recommendations is being reported in the April 30 issue of the New England Journal of Medicine. The study found that not starting HIV patients at a CD4 count greater than 500 cells per cubic millimeter increased risk of death by 94 percent.
FAIRFAX, Va.--Due to regional conflicts across the globe, such as wars in Iraq and Afghanistan and the global war on terrorism, women are being deployed overseas in greater numbers than ever before. Women constitute approximately 16 percent of the 3.5 million members of the U.S. armed forces and 10 percent of present forces in Iraq and Afghanistan.
CHICAGO--When a patient is discharged from the hospital, just about the last thing he or she wants is to be back in again within the next month. But a new national study has found that's exactly what happens to one out of five Medicare patients, costing billions in health care and suffering for patients.
COLUMBIA, Mo. !-- For years, researchers and physicians have known that infants' immune systems do not respond well to certain vaccines, thus the need for additional boosters as children develop. Now, in a new study from the University of Missouri, one researcher has found an explanation for that poor response.
BUFFALO, N.Y. -- Several studies have suggested there is a connection between organisms that cause gum disease, known scientifically as periodontal disease, and the development of heart disease, but few studies have tested this theory.
