RIVERSIDE, Calif. (www.ucr.edu) – Researchers at the UC Riverside Bourns College of Engineering have built and successfully tested an amplifier made from graphene that could lead to more efficient circuits in electronic chips, such as those used in Bluetooth headsets and toll collection devices in cars.

A first-ever, long-term study of patients who underwent robot-assisted surgery to remove their cancerous prostates found that nearly 87 percent of them had no recurrence of the disease after five years.

The findings were reported in this month's issue of the European Urology journal by a team of Henry Ford Hospital researchers led by Mani Menon, M.D., an internationally recognized pioneer in the use of high-precision surgical robots.

San Antonio, Texas (October 18, 2010) – The association between obesity and gastrointestinal-related cancers and coronary artery disease; the link between an overweight or obese body mass index and the severity of Crohn's disease; and whether inflammatory bowel disease is an independent risk factor for coronary artery disease, were among the highlights of new research that was presented this week at the American College of Gastroenterology's (ACG) 75th Annual Scientific meeting in San Antonio.

Obesity Linked to Increased Liver Cancer Risk, Adenoma Recurrence

San Antonio, Texas (October 18, 2010) – Investment in screening programs that target the pre-Medicare population, individuals aged between 50 and 64, is needed to reduce the costs of colorectal cancer in the Medicare program, according to the results of a new study, "Cost-Savings to Medicare from Increased Colorectal Cancer Screening in the Pre-Medicare Population," unveiled today at the American College of Gastroenterology's (ACG) 75th Annual Scientific meeting in San Antonio, Texas.

CHICAGO—Today's Scientific Program of the 2010 American Academy of Ophthalmology (AAO) - Middle East-Africa Council of Ophthalmology (MEACO) Joint Meeting includes a report on beta carotene's ability to improve vision in people with certain incurable retinal diseases. The AAO-MEACO meeting–the world's largest, most comprehensive ophthalmic education conference–is in session October 16 through 19 at McCormick Place, Chicago.

CHICAGO—Data on glaucoma risk in people with migraine and on innovative uses of mobile, digital technology are featured in today's Scientific Program, to be presented at the 2010 American Academy of Ophthalmology (AAO) – Middle East-Africa Council of Ophthalmology (MEACO) Joint Meeting. The AAO-MEACO meeting is in session October 16 through 19 at McCormick Place, Chicago. It is the largest, most comprehensive ophthalmic education conference in the world.

The Blood Pressure-Glaucoma Connection in People with Migraine

"The results have exceeded our expectations! I would like to claim that there has been no previous study with similar effects on healthy subjects", says Inger Björck, professor of food-related nutrition at Lund University and head of the University's Antidiabetic Food Centre.

Forty-four healthy, overweight people between the ages of 50 and 75 took part in the diet study. For four weeks they ate foods which are presumed to reduce low-grade inflammation in the body, a condition which in turn triggers metabolic syndrome and thus obesity, type 2 diabetes and cardiovascular disease.

ChoiceBatter's® transformation from a federal laboratory bench technology to a grocery shelf product is among topics that will be discussed here today by U.S. Department of Agriculture (USDA) officials and other participants attending the 17th annual conference of the National Association of Seed and Venture Funds (NASVF).

Human adhesives are famed for their fallibility. Gooey glues soon lose their grip, are easily contaminated and leave residues behind. But not gecko feet. Geckos can cling on repeatedly to the smoothest surfaces thanks to the self-cleaning microscopic spatula-shaped hairs (setae) that coat the soles of their feet. Back in 2002, Kellar Autumn found that these dry hairs are in such intimate contact with surfaces that the reptiles 'glue' themselves on by van der Waals forces with no need for fluid adhesives.

Discovery of a molecular switch that turns off the natural process of skin pigmentation may lead to a novel way of protecting the skin – activating the tanning process without exposure to cancer-causing UV radiation. In their report in the journal Genes & Development, researchers from the Massachusetts General Hospital (MGH) Cutaneous Biology Research Center (CBRC) describe how blocking the action of this switch – an enzyme called PDE-4D3 – in the skin of mice led to a significant increase in melanin production.

Little kids believe the darnedest things. For example, that a fat man in a red suit flies through the air on a sleigh pulled by reindeer. A new study on three-year-olds, published in Psychological Science, a journal of the Association for Psychological Science, finds that they aren't just generally trusting. They're particularly trusting of things people say to them.

PROVIDENCE, R.I. [Brown University] — In as many as 8 percent of pregnancies worldwide, women who seem fine for months develop preeclampsia, a serious complication causing symptoms including high blood pressure, severe swelling, and problems with placental development. The untreatable and unpredictable condition, with no known cause, often requires premature delivery, and can sometimes kill the mother and the fetus.
