New high-resolution data on intact ribosome

A new, sharper picture of the nano-machine that translates our genetic program into proteins promises to help researchers explain how some types of antibiotics work and could lead to the design of better ones.

Scientists discover molecular structure related to cell growth and cancer

Researchers discovered a special type of molecular structure that helps keep genes properly turned off until the structure is ejected from those genes in a regulated manner to help turn the genes on.

Electron-beam computed tomography - a more accurate replacement for coronary catheterizations

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

New insights that advance the current model of protein motility and muscle contraction

Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction.

Scientists measure with unprecedented accuracy the strengths of hydrogen bonds in a protein

The scientists were then able to predict the function of different versions of the protein based on structural information, a novel outcome that was published recently in the Proceedings of the National Academy of Sciences.

African-American women with mitochondrial DNA variant are at increased risk of breast cancer

African-American women who carry the 10398A mitochondrial DNA allele are 60 percent more likely to develop invasive breast cancer than African-American females without that genetic marker, according to research published in the September 1 issue of "Cancer Research."

New way to "image" the internal chemistry of bacteria

As part of the search for better ways to track and clean up soil contaminants, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have developed a new way to "image" the internal chemistry of bacteria.

Chemists synthesize new class of carbenes - potential for pharmaceutical industry

Chemists at the University of California, Riverside have synthesized a new class of carbenes - molecules that have unusual carbon atoms - that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs.

Analytical tool to help detect cancer

Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

Electron-beam computed tomography best for evaluating adults with congenital defects in the heart arteries

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for identifying which adult patients face the greatest risk of sudden death from congenital abnormalities in the arteries supplying blood to the heart, according to a study in the September 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

New insights into dietary divergences between some of our human ancestors

A Penn State researcher is part of the team that developed techniques that have generated insights into dietary divergences between some of our human ancestors, allowing scientists to better understand the evolutionary path that led to the modern-day diets that humans consume.

New way to prevent macular degeneration

Two studies from an unusual research partnership at the University of Chicago appear to have resolved a long-standing dispute about the role of melanin in the eye. The studies, one published in the Proceedings of the National Academy of Sciences (PNAS) and one early online in the Journal of the American Chemical Society (JACS), also suggest a new way to prevent a common cause of blindness.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

Biologists determine structure of a common-cold virus

Biologists at Purdue University have determined the combined structure of a common-cold virus attached to a molecule that enables the virus to infect its host, information that ultimately may help researchers develop methods for treating certain viral infections.

Cranberry juice may be effective in treating a number of gastrointestinal viruses

Cranberry juice, long considered a home remedy for urinary tract infections, may also be effective against a number of gastrointestinal viruses according to researchers from St. Francis College in Brooklyn, New York. They report their findings today at the 105th General Meeting of the American Society for Microbiology.
