New approach to predict protein function

In a paper published online this month in the journal Nature Chemical Biology, researchers report that they have developed a way to determine the function of some of the hundreds of thousands of proteins for which amino acid sequence data are available, but whose structure and function remain unknown.

Startling discovery on the development of human embryonic stem cells

In this week's Nature, researchers of the McMaster Cancer and Stem Cell Research Institute show that human embryonic stem (ES) cells can actually produce distinctive niche cells, which then release stem-cell nourishing proteins to help keep their parents ticking over.

Chemically-modified mitochondrial toxin could lead to a new molecularly-targeted chemo drug

A chemically-modified version of a mitochondrial toxin long used to control species of invasive fish in lakes has been found to selectively inhibit two "survival proteins" in cancer cells.

White blood cells are picky about sugar

Biology textbooks are blunt - neutrophils are mindless killers. These white blood cells patrol the body and guard against infection by bacteria and fungi, identifying and destroying any invaders that cross their path. But new evidence, which may lead to better drugs to fight deadly pathogens, indicates that neutrophils might actually distinguish among their targets.

Obesity rate in the U.S. has increased at an alarming rate over the past three decades

The U.S. obesity prevalence increased from 13 percent to 32 percent between the 1960s and 2004, according to researchers at the Johns Hopkins Bloomberg School of Public Health Center for Human Nutrition.

Researchers measure effect of hepatitis B on patients' quality of life

"Am I going to die? I have no future." "I feel depressed at times, fearful I may not see my children marry or be a grandparent." Such heart-rending statements from patients with chronic hepatitis B reveal the social and mental impact of this disease, which affects 350 million worldwide.

Master switch for the production of brown fat discovered

Researchers at Dana-Farber Cancer Institute have identified a long-sought "master switch" in mice for the production of brown fat, a type of adipose tissue that generates heat and counters obesity caused by overeating.

Neural stem cells for Parkinson's disease

A University of South Florida neuroscientist reports that the cutting-edge research study of human stem cells in primates with Parkinson's disease is compelling on several fronts , particularly how the transplanted cells did their job of easing disease symptoms.

Magnetic resonance spectroscopy for breast cancer

The American Cancer Society recently issued new recommendations for women with a higher risk of developing breast cancer, including those with a family history of breast or ovarian cancer, and those who may carry genetic mutations (BRCA1 or BRCA2) that make them more likely to develop the disease.
