(PhysOrg.com) -- There are over 400 genetically different dog breeds, with massive variations in size, colors, fur type, temperament, and so on, and scientists have wondered exactly what changes in the genes have been brought ...
(PhysOrg.com) -- A new study by mathematicians in Australia has explained how skin remains stable in water and does not dissolve, and why it wrinkles and remains a strong barrier even after absorbing large quantities of water.
From an electron's point of view, graphene must be a hair-raising thrill ride. For years, scientists have observed that electrons can blitz through graphene at velocities approaching the speed of light, far faster than they ...
