Gene keeps neural cells on correct developmental path

Embryonic stem cells with identical genomes grow into distinctive tissues, such as heart, bone, and brain. At one time, scientists believed the differences among cell types arose from various sets of genes switched on inside developing cells. Then, studies showed that adult neurons uniquely lack a protein that permanently turns off neuronal genes in the rest of the body's cells. Now, it tu...

High fidelity keeps human DNA assembly line humming

Scientists at Michigan State University have made a major discovery on the inner workings of genetic coding, mapping out mechanisms of one of life's most elemental functions: RNA synthesis. Their work has crucial implications for how a normal cell forms a tumor and how a virus runs amok. Behind th...

Life-extending protein keeps blood sugar in check

A protein that extends lifespan in yeast, worms, and flies keeps blood sugar under control in mice, reports a new study in the August Cell Metabolism. The findings suggest therapeutic interventions for the prevention and treatment of metabolic disorders, such as type 2 diabetes, which frequently arise with age, the researchers said. The team found that mice with an excess of the protein Si...

A resetting signal keeps circadian rhythm on track in Drosophila fruit flies

A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). The two key groups of neurons control morning and evening activity and are maintained in synch even when the flies are plunged into darkness for extended periods of time. <...

Unusual mechanism keeps repair protein accurate

Cancer researchers have discovered that a recently identified protein critical for repairing damaged genes uses an unusual mechanism to keep its repairs accurate. But while other DNA-repair proteins insure their accuracy with...

Garlic a day keeps cancer away

To reduce your risk of bowel cancer, a single raw clove of garlic can do wonders say the researchers from Boston University. Garlic is best known for staying off heart disease and it also has powerful anti-cancer properties.A substance called diallyl disulfide in garlic is known to make the gut produce enzymes that clear out cancer-causing particles. Now two New Zealand s...

Caffeine keeps soldiers sharp

Caffeine can help increase reaction time and improve performance for military servicemen who must perform complex tasks or who need help staying alert for longer periods of time, according to a new report by the National Academy of Sciences. The report, by the academy's Institute of Medicine, found that 100 to 600 mg of caffeine, the equivalent of one to six cups of coffee, can help "maintain cog...

Gene block keeps mice from increasing weight

Researchers at the University of Wisconsin have observed that mice lacking a specific gene can eat a high-fat diet without either putting on weight or developing diabetes. The gene called SCD-1 codes for a protein which the body needs to make the fatty acids found in fat tissue.//They have created a 'knockout' mouse that lacks SCD-1. Such animals can eat a rich, high-fat diet but do not put on we...

A Tomato a Day Keeps Heart Disease Away

Just one serving a day of tomato-based foods such as pizza or tomato sauce could lower your risk for heart disease by as much as 30 percent, according to a new Harvard study. "The results are pretty enticing," says study author Howard Sesso, an assistant professor at the Harvard School of Public Health and Brigham and Women's Hospital in Boston. "They're encouraging enough for us to do more studi...

Drug Keeps The Weight Off

It has been shown that the drug Rimonabant (Acomplia) a selective cannabinoid receptor blocker (CB1), can help obese patients keep weight off // . Supplementation with 20 milligrams of rimonabant a day resulted in a significant decrease in body weight and waist circumference -- a marker of cardiovascularly dangerous visceral fat. It also improved HDL (good) cholesterol, triglycerides, and the pr...
