Slowing or preventing the development of Alzheimer´s disease, a fatal brain condition expected to hit one in 85 people globally by 2050, may be as simple as ensuring a brain protein´s sugar levels are maintained. That´s the conclusion seven researchers, including David Vocadlo, a Simon Fraser University chemistry professor and Canada Research Chair in Chemical Glycobiology, make in the latest issue of Nature Chemical Biology. The journal has published the...

Genetic mutations to cellulose in plants could improve the conversion of cellulosic biomass into biofuels, according to a research team that included two Iowa State University chemists. Mei Hong, an Iowa State professor of chemistry and an associate of the U.S. Department of Energy's Ames Laboratory, and Tuo Wang, an Iowa State graduate student in chemistry, contributed their expertise in solid-state nuclear magnetic resonance spectroscopy to the study. The study was led by Seth DeBolt,...

A team of researchers at Karolinska Institutet has generated a map over the effects of small drug-like molecules on PARP1 and other similar proteins in the body. This map may explain the mechanism behind putative side effects of the so-called PARP inhibitors, and can play an important role in the development of novel tailor-made cancer drugs. The study is presented in the journal Nature Biotechnology, and will hopefully contribute to new cancer therapies with fewer detrimental side effects....

Fresh insights into how our cells multiply could help scientists develop drugs to treat cancer Fresh insights into how our cells multiply could help scientists develop drugs to treat cancer. Researchers have gained better understanding of the workings of two key proteins that control cell division. This process must be carried out accurately to keep cells healthy, and when it goes out of control, it can lead to cancer. The study, led by the University of Edinburgh, could contribute...

In “Mass Extinctions: Nature´s Spectacular Staging of Natural Selection” Julian Lieb, M.D  provides evidence that “die-offs” or mass deaths are episodes of natural selection, caused by activation of enzymes of the arachidonic acid cascade. In prior publications, Dr Lieb showed that products of the arachidonic acid cascade are the agents of natural selection and evolution, differentiating between infertility and reproduction, and between health and...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
