Physicists from the Georgia Institute of Technology have developed a theory that describes, in a unified manner, the coexistence of liquid and pinned solid phases of electrons in two dimensions under the influence of a magnetic field. The theory also describes the transition between these phases as the field is varied. The theoretical predictions by Constantine Yannouleas and Uzi Landman, from Georgia Tech´s School of Physics, aim to explain and provide insights into the origins of...

From Earth, the Sun looks like a calm, placid body that does little more than shine brightly while marching across the sky. Images from a bit closer, of course, show it's an unruly ball of hot gas that can expel long plumes out into space "“ but even this isn't the whole story. Surrounding the Sun is a roiling wind of electrons and protons that shows constant turbulence at every size scale: long streaming jets, smaller whirling eddies, and even microscopic movements as charged particles...

Scientists looked at the failure of coordination in sophisticated networks from the Web to flocking birds Individuals within a networked system coordinate their activities by communicating to each other information such as their position, speed, or intention. At first glance, it seems that more of this communication will increase the harmony and efficiency of the network. However, scientists at Rensselaer Polytechnic Institute have found that this is only true if the communication and its...

New technique allows injections into individual cells Duke University physicists have developed a way to produce sharp fluid jets with enough precision that they can inject material into a single, living cell. The technique promises a way to deliver drugs to cells one at a time, which is likely to be very valuable for research involving stem cells and other cellular-level studies. The research appears in the current issue of the APS journal Physical Review Letters. The physicists produced the...

Making contact Using large-scale supercomputer calculations, researchers have analyzed how the placement of metallic contacts on graphene changes the electron transport properties of the material as a factor of junction length, width and orientation. The work is believed to be the first quantitative study of electron transport through metal-graphene junctions to examine earlier models in significant detail. Information on the ways in which attaching metal contacts affects electron transport...

A mathematical model of a simple circuit in a chicken brain raises fundamental questions about our understanding of neural circuitry The Web site Neuroanthropology asks visitors to complete this quote, "One of the difficulties in understanding the brain is "¦". In addition to the typical facetious remarks, such as "so few of us seem to have one" and "the damn thing is smart enough to realize what you are doing, and contrary enough to change the way it reacts just to spite...

Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter". But scientists from the University of Gothenburg have shown that there is another explanation of the flux. Several independent studies recently discovered a mysterious flux of electrons and positrons in the universe. Several theories were presented that suggested that these particles arise from the decay of "dark matter" -...

Word of the Day
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
