Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

...more efficiently, reducing industrial purification costs before and after running a reaction and permitting the production of new, unprecedented materials. "By reducing the level of the copper catalyst used in ATRP, we have made this process at least 100 times more efficient and much more amenable to ind...

Study highlights new and cheaper way to treat heroin addiction

...proved controversial not least because of the high costs involved. In contrast to methadone –which comes in liquid not tablet form ?dihydrocodeine is much easier to store and comes under less stringent regulations because it is not as toxic and less likely to cause a fatal overdose. It is estimated that...

Biodegradable napkin -- featuring sensitive nanofibers -- may quickly detect biohazards

...orporated into conventional paper products to keep costs low. Nanofibers, with diameters near 100 nanometers (a nanometer is one-billionth of a meter, or about three times the diameter of an atom), provide extremely large surface areas for sensing and increased absorbency compared with conventional fibers....

First biomarker for human sleepiness identified in fruit flies

...ing will get people thinking about the dangers and costs of sleep deprivation," says lead author Paul J. Shaw, Ph.D., assistant professor of neurobiology. "If you're feeling sleepy on your way over the river and through the woods to grandmother's house, it's much better to pull over and find a place where ...

Hope for major advance in fighting world killer disease

... "It's often said that, if a medical intervention costs more than US$½ it's not going to be viable in developing countries. Our test is quick, robust and cheap. At a workshop we held recently at Anna University, more than 30 people, ranging from technicians and students to clinical professors, had the...

Boston University biomedical engineers win major grant for pursuit of the '$1,000 Genome'

...e pairs on a human genome using current technology costs about $10 million. Reducing the cost to $1,000 or less would bring DNA sequencing into the realm of routine medical care, enabling doctors to diagnose and treat patients more effectively based on their individual genetic profiles. ...

Scientists use an 'ice lolly' to find polar bacteria in their own backyard

...rofessor Walker. These findings will decrease the costs involved in the further study of such bacteria and their properties, as scientists will no longer need expeditions to the poles in order to isolate the bugs; they can find them in their own backyards. ...

Evolutionary forces explain why women live longer than men

...ompete aggressively for female attention, and that costs them something. In nature, it means riskier physiology and behavior for the males, such as putting more resources into flashy plumage or engaging in physical sparring. And even in modern life, where most dueling is a form of entertainment, male beha...

Scientific issues associated with carbon-neutral energy sources such as cellulosic ethanol

Somerville presented his talk, "Bioenergy: The 21st Century Challenge to Plant Biologists" at the Annual Meeting of the American Society of Plant Biologists (ASPB)...

Gorilla susceptibility to Ebola virus: the cost of sociality

...d disease and could shed light on the evolutionary costs experienced by primates living in groups. The authors note that thousands of gorillas have probably disappeared as a result of the Ebola outbreak studied here, and they point out that because the impact of Ebola on apes is still difficult to control,...
