Gene sequencing explains why natural bioremediation 'bug' has big appetite for chlorinated pollutants

"The born-to-dechlorinate bug" is what Cornell University researchers called Dehalococcoides ethenogenes Strain 195 when they found the bacterium obligingly detoxifying the pollutant PCE, or perchloroethylene (a chlorinated solvent used for dry cleaning), in sludge from an Ithaca, N.Y., sewage treatment plant.

Discovery of gene related to p53 called Bnip3L that can also cause cell death

Researchers have known for a decade that the p53 tumor suppressor gene is important for killing cells as they proliferate under low-oxygen conditions inside tumors.

Stem cells could reveal secrets of illness in later life

Mums to be have known for some time that what they eat when pregnant affects their unborn child but now scientists believe that the diet of our mothers during pregnancy may even affect our predisposition to illnesses such as heart disease, diabetes and high blood pressure in late life.

3 or more alcoholic drinks increases risk of ischemic stroke by 45%

A new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and the Harvard School of Public Health (HSPH) has found that heavy drinkers -- men who consume an average of three or more alcoholic beverages per day -- are nearly 45 percent more likely to suffer an ischemic stroke compared with nondrinkers.

Two recent studies are souring milk's image among health authorities

Two recent studies are souring milk's image among health authorities. One, published in the November issue of the American Journal of Clinical Nutrition, shows that women who consume two or more glasses of milk a day have twice the risk of a certain form of ovarian cancer than those who rarely or never consume milk.

Autophagy is also cell's second line of defense against invading pathogens such as strep

Cells give up their secrets slowly. Just when you think that all major cellular systems are understood, along comes a surprise. The latest is about autophagy, a major pathway for degrading and recycling within cells.

New and revealing portrait of Yersinia pestis emerges

Yersinia pestis, the causative agent of the “Black Death” or “Bubonic” plague, has been a scourge of human civilization. One of the most virulent bacterial pathogens known, killing nearly 90% of those infected, Y. pestis was responsible for three historic pandemics that shattered whole societies.

Research raises question on shark cartilage use as an anti-cancer treatment

The rising popularity of shark cartilage extract as an anti-cancer treatment is a triumph of marketing and pseudoscience over reason, with a tragic fallout for both sharks and humans, according to a Johns Hopkins biologist writing in the Dec. 1 issue of Cancer Research.

Low-dose antioxidant supplementation may reduce the risk of cancer among men, but not in women

According to the article, antioxidants including beta carotene, ascorbic acid, vitamin E, selenium, and zinc may prevent some of the harmful effects caused by free radicals – reactive molecules produced by metabolism in the body.

Researchers have identified a protein that transports the essential nutrient boron into cells

Researchers at UT Southwestern Medical Center at Dallas have identified a protein that transports the essential nutrient boron into cells, where it is important for cell growth and bone development. The findings are in the Nov. 5 edition of the journal Molecular Cell and are online.

Novel health food composition proves highly effective

A more than 50 % increase in the life span of Zucker rats, a commonly used animal model for human obesity, was seen by enrichment of unhealthy food with a novel combination of plant sterols and mineral nutrients.

Protein important to nerve development serves the dual purpose of stimulating the growth of blood vessels

The discovery opens the possibility that blood vessel growth (angiogenesis) one day may be induced, or stymied, for therapeutic use against heart disease, cancer, and other illnesses, according to Dean Y. Li, M.D., Ph.D., associate professor of internal medicine in the U of U School of Medicine's Division of Cardiology.

Scientists have found that a protein present in normal body tissues can prevent tumour growth

A team led by Dr Dave Bates, British Heart Foundation Lecturer, and Dr Steve Harper, Senior Research Fellow in the Microvascular Research Laboratories, in the Department of Physiology at Bristol University, have discovered that a type of vascular endothelial growth factor (VEGF) found in normal tissue, including blood, can prevent cancers from growing.

Genetic evidence to support an inherited tendency to retain salt

Researchers at the University of Chicago have found genetic evidence to support the sodium-retention hypothesis, a controversial 30-year-old theory that the high rate of hypertension in certain ethnic groups is caused, in part, by an inherited tendency to retain salt.

Transplanted human retinal stem cells can successfully regenerate

"We transplanted the cells early in the animals' development when all the nutrients and signals they needed for differentiation were still there," says lead author Brenda Coles, a U of T laboratory technician working under the supervision of Professor Derek van der Kooy in the Department of Medical Genetics and Microbiology. "When their eyes fully developed, the human cells survived, migrated into the sensory part of the eye and formed the correct cells."

New computational techniques that can allow medical doctors to visualise and assess micro-vessel blood flow in tumours

Researchers at the Nanyang Technological University (NTU) Singapore, have developed new computational techniques and algorithms that can allow medical doctors to visualise and assess micro-vessel blood flow in tumours.

Research opens new possibilities for the treatment of metabolic disorders such as diabetes and obesity

For the first time, researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected with the Catholic University of Leuven have shown clearly that receptors in yeast cells detect and react to nutrients in the cell.
