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 ...
All living tissue is made from proteins, and all proteins are made from a combination of the same 20 chemical building blocks, called amino acids. The difference between the proteins that make up bone, blood, hair and eyeballs ...

(PhysOrg.com) -- A design student, frustrated at having his brand new wafer-thin laptop scratched by the unwieldy and bulky plug attached to it, set about re-designing the standard British 3-pin plug that has remained unchanged ...
(PhysOrg.com) -- Folding paper into shapes such as a crane or a butterfly is challenging enough for most people. Now imagine trying to fold something that's about a hundred times thinner than a human hair and then putting ...
