Transitions are exciting. And at temperatures close to absolute zero, studying the transition from one quantum phase to another tantalizes physicists looking for a deeper understanding of the fundamental laws of the universe.Now a team of scientists at the University of Chicago has created the first direct images of the transition between phases of ultracold cesium gas, as it changes from normal to superfluid to Mott insulator, making it possible to "see" this phenomenon as it happens."These...

Most parts of living organisms come packaged with ribbons. The ribbons are proteins"”chains of amino acids that must fold into three-dimensional structures to work properly. But when for any reason the ribbons fold incorrectly, bad things can happen, and in humans misfolded-protein disorders include Alzheimer's and Parkinson's diseases.Scientists have for the past three decades tried to understand what makes proteins fold into functional units and why it happens, and several...

Microscopic objects floating in fluids move great distances at times, not just in a bell curve, disputing an Einstein theory, a U.S. university study suggests. The University of Illinois findings, to be published in the Proceedings of the National Academy of Sciences next week, raise fundamental questions concerning the statistical nature of the diffusion process, critical to drug delivery, water purification and the normal operation of living cells, engineering professor Steve Granick said....

Lausanne, Switzerland-- An international group of researchers from the EPFL (Ecole Polytechnique F©d©rale de Lausanne), the University of Texas at Austin and the European Molecular Biology Laboratory in Heidelberg, Germany have demonstrated that Brownian motion of a single particle behaves differently than Einstein postulated one century ago. Their results, to be published online October 11 in Physical Review Letters, provide direct physical evidence that validates a corrected form...

Indiana -- Light as we know it may be a direct result of small violations of relativity, according to new research scheduled for publication online Tuesday (March 22) in the journal Physical Review D. In discussing the work, physics professor Alan Kostelecky of Indiana University described light as "a shimmering of ever-present vectors in empty space" and compared it to waves propagating across a field of grain. This description is markedly different from existing theories of light, in...

Scientists can now confirm the theory of classical Brownian motion using details that Einstein missed when he first proposed it a century ago 100 years after Einstein's landmark paper, optical tweezer technology could confirm the theory of classical Brownian motion in details that Einstein missed when he first proposed it a century ago. This research is reported today in a special Einstein Year issue of the New Journal of Physics published jointly by the Institute of Physics and the German...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
