New study finds dolphins produce sounds in a similar way to humans
(PhysOrg.com) -- 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 ...

New model of protein folding helps researchers handle flood of genomic data
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, ...

Researchers discover why atoms in solids show a preference for certain structures
(PhysOrg.com) -- Nature likes some symmetries, but dislikes others. Ordered solids often display a so-called 6-fold rotation symmetry. To achieve this kind of symmetry, the atoms in a plane surround themselves ...
