POPSRoom temperature superconductivity: One step closer to the Holy Grail of physics The researchers have discovered where the charge 'hole' carriers that play a significant role in the superconductivity originate within the electronic structure of copper-oxide superconductors. These findings are particularly important for the next step of deciphering the glue that binds the holes together and determining what enables them to superconduct.

POPSPioneering Physicist John Wheeler Dies at 96 a real genius, if i am not mistaken he was Hugh Everett III's professor of physics, also he is the one the suggested the 'delayed choice' experiment that showed the experimenter can choose, AFTER THE FACT, whether the photon was in both places or just one.

POPSBefore the Big Bang - the Big Bounce Now, however, Dr Bojowald and fellow physicists are exploring territory unknown even to Einstein - the time before the Big Bang - using his new theory, called Loop Quantum Cosmology. An analysis of this, one of a series of newly-emerging theories which combine Einstein's theory of gravity (general relativity) with that of the subatomic world (quantum theory), "is supposed to provide a non-singular framework in which one could address the question of what was there before the Big Bang," he says.

POPSBrain Waves Pattern Themselves After Rhythms Of Nature Although the bulk of his work involves deriving equations, Cowan's findings mesh well with laboratory data generated on the cerebral cortex and electroencephalograms. His latest findings show that the same mathematical tools physicists use to describe the behavior of subatomic particles and the dynamics of liquids and solids can now be applied to understanding how the brain generates its various rhythms.

POPSFinding the Shapes of Alternative Spatial Dimensions String theory proposes that particles, described in the Standard Model as point-like entities, are in fact more like vibrating strings of energy. The different frequencies at which they vibrate through the fabric of space-time gives them their unique physical properties. Gary Shiu, professor from the University of Wisconsin-Madison, proposes a model in which the shape of the extra spacial dimensions determines the properties of the universe, much in the same way the shape of a musical instrument determines its sound, meaning that string theory predicts that the particle masses and the forces exerted in the universe are in direct relation to the vibrating frequency of the string which, in turn, is given by the shape of the spatial dimensions.
