12-08-31 Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science. According to the scientists, more...
12-05-31 An international research team has manufactured a new protein that can combat deadly flu epidemics. The paper, featured on the cover of the current issue of Nature Biotechnology, demonstrates ways to use manufactured genes as antivirals, which disab...
12-04-10 The ranking of a monkey within her social environment and the stress accompanying that status dramatically alters the expression of nearly 1,000 genes, a new scientific study reports. The research is the first to demonstrate a link between social st...
12-04-05 It has long been recognized that autism runs in families, suggesting a substantial(大量的,实质的) genetic component to the disease. Yet few genes have so far been identified and the underlying genetic architecture of autism -- that is, how many g...
12-01-10 As an embryo develops, different genes are turned on in different cells, to form muscles, neurons and other bodily parts. Inside each cell's nucleus, genetic sequences known as enhancers act like remote controls, switching genes on and off. Scientis...
11-12-18 Any multicellular(多细胞的) animal, from a blue whale to a human being, poses a special difficulty for the theory of evolution. Most of the cells in its body will die without reproducing, and only a privileged few will pass their genes to the next...
11-10-27 Most genes associated with psychiatric illnesses are expressed before birth in the developing human brain, a massive study headed by Yale University researchers discovered. In addition, hundreds of genetic differences were found between males and fe...
11-10-26 Patients with certain genes or specific factors related to use of the anti-clotting drug clopidogrel are more likely to experience a blood clot within a coronary(冠状的) stent shortly after placement, according to a study in the October 26 issue o...
11-10-20 It has long been known that distinctive blue flashes--a type of bioluminescence--that are visible at night in some marine environments are caused by tiny, unicellular(单细胞的) plankton known as dinoflagellates(鞭毛藻类) . However, a new study h...
11-10-12 A long-held mantra(咒语) suggests that you can't change your family, the genes they pass on, or the effect of these genes. Now, an international team of scientists, led by researchers at McMaster and McGill universities, is attacking that belief....
