Physicists explore superconductivity at the two-dimensional limit

more »
Researchers show that the superconducting state can be maintained even when the material in question is reduced from three to two dimensions, making the efficiency gains needed for technologies like those underlying the frictionless train possible.

The SONG and the Hunter

more »
Near first quarter, the Moon in March lights this snowy, rugged landscape, a view across the top of Tenerife toward La Palma in the Canary Islands Spanish archipelago. The large Teide volcano, the highest point in Spain, looms over the horizon. Shining above are familiar bright stars of Orion, the Hunter. Adding to the dreamlike scene is the 1 meter diameter prototype telescope of the global network project called the Stellar Observations Network Group or SONG. The SONG's fully robotic observatory was captured during the 30 second exposure while the observatory dome, with slit open, was rotated across the field of view.
