Evidence of macroscopic quantum tunneling detected in nanowires

Researchers have demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to 'tunnel' as a pack from a state with a higher electrical current to one with a notably lower current, providing more evidence of the phenomenon of macroscopic quantum tunneling.

Pore effort: Physicist unravels 'hole' story of cell suicide

Rice physicist Huey Huang is on a quest to understand death -- or at least a little piece of it. Huang has spent the past 15 years studying the properties of cell membranes in an effort to unravel a mystery about cell suicide, a mystery that starts with a tiny hole.
