Features
    Magnesium Diboride: Better Late Than Never
    With a superconducting transition temperature of 40 K and two superconducting gaps, MgB2 is full of surprises for both experimentalists and theorists -- Paul C. Canfield and George W. Crabtree
 
    Although she made essential contributions toward elucidating the structure of DNA, Rosalind Franklin is known to many only as seen through the distorting lens of James Watson's book, The Double Helix -- Lynne Osman Elkin
   
    Flexibility and time resolution make LEEM a powerful tool for studying mesoscale phenomena--from surface diffusion to magnetization -- Raymond J. Phaneuf and Andreas K. Schmid

    First results from the Kamland detector in Japan home in on the parameters of solar-neutrino flavor oscillation.
   
    Simple physics says huge amounts of gas in cluster cores should cool and collapse. Simple physics is wrong--but why?
 
    Making movies of stirred-up beads illuminates the baffling problem of turbulence.
  Issues & Events
 
    Defense programs and physical sciences see increases in the administration's fiscal year 2004 budget proposal, but much of the rest of science funding is flat or down.
 
    President Bush, heeding recommendations from the fusion science community, the National Research Council (NRC), and the Department of Energy (DOE), authorized the US to rejoin the International Thermonuclear Experimental Reactor project.
 
    Not just cosmetic: L'Oréal and UNESCO are rewarding five women from around the globe for their scientific contributions in crystallography, disordered materials, scaling laws of fluids and complex systems, and electron microscopy of crystals and quasicrystals.
 
    Next month sees the launch of the greatest expansion of faculty positions for science, technology, and security policy since the end of the cold war.
 
    Minutes after it took off on 11 December from Kourou, French Guiana, the Ariane 5 rocket plunged into the Atlantic Ocean with two telecommunications satellites on board. The mishap means the European Space Agency's ambitious comet probe, Rosetta, will be delayed--and must find a new target.
 
    Given the good impression Robert Aymar made last year as chair of an external review committee for CERN, it's no surprise he's been named director general of the European particle physics lab.
   
    Praveen Chaudhari, a longtime scientist and manager at IBM, has been named as the new director of Brookhaven National Laboratory.
   
    The bush fires, which ravaged more than 1050 km2 of land, destroyed the observatory's three domes, six telescopes, equipment workshops, eight staff houses, and an administration building.
   
    On 1 January, Richard Schilizzi took the reins as inaugural director of the SKA. And on 5 May, Robert L. Brown will take the helm of the Cornell University-run National Astronomy and Ionosphere Center.

Cover: This scanning electron microscope image shows the cross section of a magnesium diboride wire, about 150 mm in diameter, that was synthesized by exposing a boron filament to magnesium vapor. Two years ago, superconductivity was discovered in MgB2 at surprisingly high temperatures. Research into the basic physical properties of MgB2 revealed unique and fascinating behavior. Beginning on page 34, Paul Canfield and George Crabtree review the current understanding of this remarkable superconductor.
