16-01-29 A new study published in the Journal of Medical Entomology is the first to report that bed bugs have developed resistance to a class of insecticides known as neonicotinoids, or neonics, the shortened name. Neonics are the most widely used group of i...
15-02-25 Researchers at the University of California, Riverside have invented a novel pretreatment technology that could cut the cost of biofuels production by about 30 percent or more by dramatically reducing the amount of enzymes needed to breakdown the ra...
14-11-25 Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as active sites. But scientists lack basic information about their function because the states tho...
14-03-27 Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene(蒎烯) , a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missi...
12-11-16 A new study by researchers at Imperial College London has identified a way in which Salmonella bacteria, which cause gastroenteritis(肠胃炎) and typhoid(伤寒) fever, counteract the defence mechanisms of human cells. One way in which our cells fi...
12-08-21 In evaluating the bioactive compounds of Illinois blueberry and blackberry wines, University of Illinois scientists have found compounds that inhibit enzymes responsible for carbohydrate(碳水化合物) absorption and assimilation(同化,吸收) . And...
11-03-18 Plants are continually exposed to herbivore(食草动物) attack. To defend themselves, they have developed sophisticated chemical defense mechanisms. Plants of the mustard family, such as thale cress (Arabidopsis thaliana), produce glucosinolates (mu...
10-08-27 For the first time ever, a completely man-made chemical enzyme(酶) has been successfully used to neutralise(中和,使无效) a toxin found naturally in fruits and vegetables. While studying for her PhD in chemistry at the University of Copenhagen D...
10-07-30 Scientists at the Buck Institute for Age Research have discovered that a particular family of enzymes(酶) are involved in the breakdown(分解,故障) of proteins that modify the production of toxic fragments that lead to the pathology(病理学) of...
09-12-14 Researchers at The Scripps思科利普斯 Research Institute have solved a 10-year-old mystery of how a single protein from an ancient family of enzymes酶类,酵素 can have two completely distinct roles in the body. In addition to除之外 providing guidance...
