Darfur Stoves Project

Darfur Stoves Project

Since the Darfur crisis began in 2003, women living in the refugee camps walked for up to seven hours outside the safety of the camps to collect firewood for cooking, putting them at risk for violent attacks. Now, researchers at Lawrence Berkeley National Laboratory have engineered a more efficient wood-burning stove, which is greatly reducing both the women's need for firewood and the threats against them.

"I Flamed Amazement": The Physics of St. Elmo's Fire

Ariel personified St. Elmo's Fire, the glow that can appear around ship masts and chimneys during a thunderstorm. Lacking a scientific explanation for the light, people in Shakespeare's time attributed it to the patron saint of sailors. Four hundred years later, we still don't completely understand how storms create such magnificent atmospheric phenomena.
