Magnetic avalanche triggered by quantum effects: "Barkhausen noise" detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to t.....»»
Research team proposes a novel type of acoustic crystal with smooth, continuous changes in elastic properties
In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye that is not focused by the.....»»
Research suggests natural electrical grid deep inside Earth enables many types of microbes to survive
To "breathe" in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons (produced during the "burning" of nutrients) to electric hairs called nanowires projecting fro.....»»
