Physics Today (Top 10 items)

  1. Agilent helps scientists explore the nature of matter ---Sponsorship (Tue Jun 1 8:00 am)
    High-energy particle accelerators are helping researchers investigate questions about the origins of the universe. Typical experiments involve controlled collisions between either intersecting particle beams or a beam and an atomic-scale target....
  2. High Energy Density Physics (Tue Jun 1 8:00 am)
    The novel, mysterious, and controversial behavior of matter at high pressure involves the interplay of electromagnetic, statistical, quantum, and relativistic physics.
  3. Magnetic field reconnection: A firstprinciples perspective (Tue Jun 1 8:00 am)
    Recent satellite missions and computer simulations of charged-particle dynamics in Earth's magnetosphere are helping unravel the mysteries behind the breaking and reforming of magnetic field lines and the concomitant acceleration of electrons...
  4. James Franck: Science and conscience (Tue Jun 1 8:00 am)
    In World War I, Franck helped his native Germany develop gas-warfare defenses. Three decades later he urged the US, his adopted country, to tread carefully with an even more terrible weapon.
  5. Focus on improving transmission electron microscopes starts to pay off. (Tue Jun 1 8:00 am)
    Two isotopes of the newly discovered element decay to give nine more previously unobserved nuclei.
  6. Yoking real and virtual cells confirms theory of cochlear amplification (Tue Jun 1 8:00 am)
    Elastic coupling between cells in the inner ear enhances the hearing of amphibians, reptiles, birds, and mammals.
  7. Focus on improving transmission electron microscopes starts to pay off (Tue Jun 1 8:00 am)
    The latest advance is the chemical identification of closely spaced, lightweight atoms.
  8. Physics update (Tue Jun 1 8:00 am)
  9. Megalasers to pulse in several new EU countries (Tue Jun 1 8:00 am)
    As the world celebrates 50 years since the invention of the laser, a European facility approaching exawatt power is expected to stimulate new research areas and communities.
  10. DOE begins rationing helium-3 (Tue Jun 1 8:00 am)
    As the extent of the shortage becomes clear, an interagency task force is giving scientific users priority, but some say the material is not available at any price.
