Obesity doesn’t play favorites when it comes to prostate cancer recurrence

DURHAM, N.C. – A new look at a large database of prostate cancer patients shows that obesity plays no favorites when it comes to increasing the risk of recurrence after surgery: Being way overweight is equally bad for blacks and whites, say researchers at Duke University Medical Center.

Why are autumn leaves red in America and yellow in Europe?

Walking outdoors in the fall, the splendidly colorful leaves adorning the trees are a delight to the eye. In Europe these autumn leaves are mostly yellow, while the United States and East Asia boast lustrous red foliage. But why is it that there are such differences in autumnal hues around the world? A new theory provided by Prof. Simcha Lev-Yadun of the Department of Science Education- Biology at the University of Haifa-Oranim and Prof.

Energy efficient sewage plants

Sewage plants remove organic matter from wastewater. If the accumulating sludge decays, biogas is generated as a by-product. However, only 1156 of the 10,200 sewage plants in Germany have a digestion tank. Smaller operations, especially, baulk at the costs of a new digestion tank. Instead, they enrich the sludge with oxygen in the existing activation basin, and stabilize it. "Activation basins require a lot of electricity. At the same time, enormous energy potential is lost, since no biogas is produced," says Dr.

Molecules wrestle for supremacy in creation of superstructures

LIVERPOOL, UK – 13 August 2009: Research at the University of Liverpool has found how mirror-image molecules gain control over each other and dictate the physical state of superstructures.

Scarring key to link between obesity and diabetes

The team, in collaboration with University Hospital Aintree, the University of Warwick and researchers in Sweden, found that people classified as obese and those with pre-diabetes have raised levels of a protein called SPARC, that can cause tissue scarring. The research revealed that an increase in insulin, a hormone that controls blood sugar levels, and leptin, a hormone that regulates appetite, can trigger an increase in SPARC, which can prevent the proper storage of fat in fat tissue cells.

Interventional radiology treatment for uterine fibroids: Safe, nonsurgical option

"Publishing this information in the New England Journal of Medicine will further prompt physicians to discuss all treatment options for symptomatic uterine fibroids—including UFE—if they are not already doing so," said Goodwin. "A woman seeking treatment for her fibroids should be aware of all of her treatment options.

New study suggests possible genetic links between environmental toxins and multiple myeloma

North Hollywood, CA– August 13, 2009 - The International Myeloma Foundation (IMF)—supporting research and providing education, advocacy and support for myeloma patients, families, researchers and physicians—today said newly published data may provide a possible genetic link between environmental toxins and bone disease in multiple myeloma. Myeloma, also called multiple myeloma, is a cancer of cells in the bone marrow that affect production of blood cells and can damage bone.

Cancer mortality rates experience steady decline

PHILADELPHIA – The number of cancer deaths has declined steadily in the last three decades. Although younger people have experienced the steepest declines, all age groups have shown some improvement, according to a recent report in Cancer Research, a journal of the American Association for Cancer Research.

Gene therapy 1 year later: Patients healthy and maintain early visual improvement

Three young adults who received gene therapy for a blinding eye condition remained healthy and maintained previous visual gains one year later, according to an August online report in Human Gene Therapy. One patient also noticed a visual improvement that helped her perform daily tasks, which scientists describe in an Aug. 13 letter to the editor in the New England Journal of Medicine.

Vision improvement after gene therapy maintained at 1 year for inherited retinal blindness

PHILADELPHIA – One year after a trio of young adults received gene therapy for an inherited form of blindness, researchers have documented that the patients are still experiencing the same level of remarkable vision improvements previously measured within weeks. This is the first study to report one-year gene therapy safety and efficacy results in treating young adults with Leber Congenital Amaurosis (LCA), a hereditary condition that causes severe vision impairment in infants and children.

PR pros are good ethical thinkers, study finds

For years journalists and others have questioned the ethics of public relations practitioners and firms. People in PR, however, appear to be getting a bad rap. That's what a new study funded by the Arthur W. Page Center for Integrity in Public Communication at Penn State University has found.

The research, conducted by two of the Page Center's Johnson Legacy Scholars, Renita Coleman and Lee Wilkins, is the first to measure empirically the moral development of working public relations professionals.

Fungus found in humans shown to be nimble in mating game

PROVIDENCE, R.I. [Brown University] — Brown University researchers have discovered that Candida albicans, a human fungal pathogen that causes thrush and other diseases, pursues same-sex mating in addition to conventional opposite-sex mating.

Scientists have observed this same-sex mode of reproduction in other fungi, but this is the first time they have identified it in Candida albicans, the most common human fungal pathogen.

Details are highlighted in the August 2009 edition of the journal Nature.

Scientists demonstrate importance of niche differences in biodiversity

(Santa Barbara, Calif.) –– Scientists at UC Santa Barbara have found strong evidence that niche differences are critical to biodiversity. Their findings are published online in this week's issue of the journal Nature.

"Ecologists have long assumed that species differences in how they use the environment are key to explaining the large number of species we see all around us, but the importance of such niches have never been field tested," said first author Jonathan M. Levine, associate professor in UCSB's Department of Ecology, Evolution, and Marine Biology.

Uncovering the secrets of ulcer-causing bacteria

A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.

Study finds migratory birds not picky about their rest stops

WEST LAFAYETTE, Ind. - If a lush, protected forest with a winding stream is considered luxury accommodation for a migratory bird, a Purdue University study shows that those birds would be just as happy with the equivalent of a cheap roadside motel.
