(PhysOrg.com) -- With a strength 200 times greater than that of steel, graphene is the strongest known material to exist. But now scientists have found that folding graphene nanoribbons into structures they call “grafold” ...
It has long been thought that dolphins produce sounds by means of "whistles," but a new analysis of a data gathered in the late 1970s has revealed that instead, dolphins make sounds by means of tissue vibrations, in a similar ...
Protein folding has nothing to do with laundry. It is, in fact, one of the central questions in biochemistry. Protein folding is the continual and universal process whereby the long, coiled strings of amino acids that make ...
