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.

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.
