Voltage flip turns magnetism on, off
Researchers in Japan have made a material whose inherent magnetism can be turned off and on electrically, as long as the material, a novel semiconductor, stays ultracold.

Collider is cookin’, but is it soup?
By making the densest, hottest matter ever in a lab, smashups between fast-moving nuclei in the Relativistic Heavy Ion Collider are coming closer than ever to reproducing the superhot, primordial fluid that presumably filled the universe immediately after the Big Bang.

Magnetic Whispers
Promising new ways to magnetically probe tissues and substances are emerging now that a small research group has proved their once-ridiculed claim of a flaw in the 50-year-old theory behind magnetic resonance imaging (MRI) and similar analytic techniques.

Soybeans could beef up plywood glues
Researchers have replaced animal protein with soybean protein in experimental plywood glue, potentially reducing cost and health worries.

Heating, simulations get the drop on drips
Air can buoy a layer of oil and, perhaps, even water leaking through a ceiling, if the air is relatively warm compared with the liquid.
