Sir Martin Evans won the most prestigious award in science, the Nobel Prize, for “a series of ground-breaking discoveries concerning embryonic stem cells and DNA recombination in mammals.” This fulfilled a boyhood dream for Sir Martin and firmly placed the Cardiff bio science centre on an international stage. He was one of three recipients of […]
Scientifically Souped-Up Foods
As scientists begin to understand how plant substances work, they look ahead to the time when they can apply their knowledge either to improve on or to supplement Mother Nature. Genetic engineering and selective breeding could ultimately create plant stocks with more healthful phytochemical “fingerprints.” Scientists already know that all foods are not created equal. […]
Good news for obese people, Protein behind overeating identified
Researchers, for the first time, have demonstrated in mice that a protein called brain-derived neurotrophic factor (BDNF) is critical in managing satiety, and is the main cause behind obesity and overeating. The study, led by Maribel Rios, PhD, and assistant professor of neuroscience at the Sackler School of Graduate Biomedical Sciences at Tufts University […]
Pill that cuts 40% cholesterol in 2 weeks
Scientists have developed a pill than can cut cholesterol by 40 percent within two weeks, good news for thousands of patients who are unable to take statins or the hypolipidemic drugs used to lower cholesterol levels. Researchers at Swedish pharmaceutical firm Karo Bio, who carried out tests of the pill on humans and mice, […]
Seymour Benzer, father of behavioral genetics, died on Nov 30, 2007.
Seymour Benzer, a founder of the field of modern genetics, died from a stroke on Friday, November 30, at Huntington Hospital in Pasadena. He was 86. An emeritus professor at the California Institute of Technology, Benzer’s lasting impact on modern-day genetics can be seen in continuing work whose foundations he helped lay. Studies in gene […]
Long term memory controlled by molecular pathway at synapses.
Even for a fruit fly, learning and memory are important adaptive tools that facilitate survival in the environment. A fly can learn to avoid what may do it harm, such as a flyswatter, or in the laboratory, an electric shock that happens when it smells a certain odor. Now Harvard University biologists have […]
