FDA sees nanotech challenges in every product category it regulates

...f nano raw materials, intermediate components, and industrial equipment items currently used by manufacturers.” “In light of this fast-rising commercialization, FDA needs to make certain that it has the tools, resources and information necessary to ensure the safety of novel products before they enter the mark...

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

...ge from radiation, mutagenic chemicals and intense industrial air particulate pollution. While the researchers did not specifically study the protein-coding regions of DNA where genes reside, Yauk notes that previous studies correlate mutations in non-coding regions with those in coding regions, and that some r...

Dirty snow may warm Arctic as much as greenhouse gases

...p regulations to mitigate global warming. Limiting industrial soot emissions and switching to cleaner-burning fuels would leave snow brighter, he says. New snow falls each year, and if it contained fewer impurities, the ground would brighten and temperatures would cool. Carbon dioxide lives in the atmosphere fo...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...d by means of a process that can be extended on an industrial scale to allow the manufacture of large quantities at a very low cost, and may even be made for personal, disposable use . The chemical mechanism to detect contaminants in a sample is very similar to that used by the immune system to identify a v...

Genome sequencing reveals key to viable ethanol production

...s into ethanol in one step, but is not used at the industrial scale yet because the first step, breaking down the plant’s cellulose, is much too inefficient. The key, Wu surmised, is to find out what enzymes the bacterium uses to accomplish its feat, and then boost its ability to produce those enzymes. The prob...
