Sensing distant tornadoes, birds flew the coop. What tipped them off?

Thu, 12/18/2014 - 10:00
A UC Berkeley-led research team found that golden-winged warblers in Tennessee fled the path of tornado-generating storms one to two days ahead, well before any local signs of troubling weather. Signs point to the use of infrasound as Mother Nature's early warning system.

Study reveals resilience of Roman architectural concrete

Mon, 12/15/2014 - 13:30
An international research team studying the mortar used to build such Roman architectural marvels as the Pantheon, Trajan’s Markets and the Colosseum has found a secret to the material's resilience. Led by scientists at UC Berkeley and Berkeley Lab, the team found that as the mortar cures, it forms a crystalline binding hydrate that prevents microcracks from propagating.

Scientists measure speedy electrons in silicon

Thu, 12/11/2014 - 12:00
Attosecond lasers provide the shortest light pulses yet, allowing observation of nature’s most short-lived events. Berkeley researchers have used these lasers for the first time to take snapshots of electrons jumping from silicon atoms into the conduction band of a semiconductor, the key event behind the transistor.
