A fire-breathing dragon helps fight ember attacks on thatched-roof buildings

Visitors to the historic mountain villages in central Japan marvel at the elegance of the steep thatched-roof farmhouses found there. Known as "gassho-zukuri," Japanese for "constructed like hands in prayer," the architectural ...

Drought fighter found in soil

Some discoveries happen by accident. Consider how Sept. 28, 1928, unfolded: Alexander Fleming, back in the lab after a vacation with the family, was sorting through dirty Petri dishes that hadn't been cleaned before he went ...

A new way to measure nearly nothing: Ultracold trapped atoms to measure pressure

Many semiconductor fabricators and research labs are under increasing pressure from, of all things, vacuum. These facilities need to remove greater amounts of gas molecules and particles from their setups as new technologies ...
