Brown-Harvard team solves mobile DNA's surgical sleight-of-hand

In a clever bit of biology called site-specific recombination, DNA can travel inside an organism, or into another organism, and perform a sort of grafting surgery that allows it to insert its chromosome into a chromosome of the target cell. The process is important because mobile DNA can carry genes that cause drug resistance or transmit viruses that cause disease or tumors that result in certain...

Prions rapidly 'remodel' good protein into bad, Brown study shows

Two Brown Medical School biologists have figured out the fate of healthy protein when it comes in contact with the infectious prion form in yeast: The protein converts to the prion form, rendering it infectious. In an instant, good protein goes bad. This quick-change "mating" maneuver sheds important light on the mysterious molecular machinery behind prions, infectious proteins that cause...

How nice, brown rice: Study shows rice bran lowers blood pressure in rats

Thousands of years ago, humans began scrubbing off and discarding the outer layer of long-grain rice, preferring the polished white kernel beneath. Now, for the first time, scientists in Japan have shown that this waste product of rice processing, called rice bran, significantly lowers blood pressure in rats whose hypertension resembles that of humans. The team reports their findings in th...

Brown seaweed contains promising fat fighter, weight reducer

The study, which was directed by Scripps Research Professor Benjamin Cravatt, Ph.D., is being published in the September 8 issue of The Journal of Biological Chemistry. The new study describes a pathway-different than the one previously suggested-for the biosynthesis of neurotransmitter lipids, N-acyl ethanolamines (NAEs), which include the endogenous cannabinoid ("endocannabinoid") ananda...

Brown scientists map structure of DNA-doctoring protein complex

More than half of the human genome is made up of bits of mobile DNA, which can travel inside the body and insert genes into the chromosomes of target cells. This DNA doctoring not only shapes species over time, it also spreads antibiotic resistance and is used by bacteria that spread Lyme disease and by viruses linked to certain forms of cancer. Last year in Nature, scientists working in...

Wholly Ingrained: White or Brown? Food War Going Racist? Get to the Heart of the Matter

Raging discussions about the wholesomeness of whole grains and unwholesomeness of visually appetizing foods, sugar coated cereals or white bread, have led companies’ flip-flop on their food strategies,// and yo-yo to consumer palettes, dictated by regular doses of general knowledge on 'Health Foods', known to keep heart disease and cancer at bay. More food for thought than consumption!...

Louisiana Residents Warned Against Brown Recluse Spiders

A poisonous brown widow spider, a cousin to the well-known black widow, is increasingly being spotted in Louisiana, experts say . It is belongs to a group that is officially known as the "recluse spiders" and are also commonly referred to as "fiddleback" spiders or "violin" spiders because of the violin-shaped marking on the top surface of the cephalothorax (fused head and thorax). <b...

Scientists Identify "master Switch" for Brown Fat in Mice

Scientists have identified a "master switch" for the production of brown fat, a type of adipose tissue that generates heat and counters obesity caused by overeating , by conducting experiments on mice. Dr. Bruce Spiegelman of Dana-Farber Cancer Institute believes that turning up the equivalent switch in humans may be a new strategy for treating obesity. The researche...
