Study compares sound from exploding volcanoes with jet engines

New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. Researchers at Scripps Institution of Oceanography at UC San Diego speeded up the recorded sounds from two volcanoes and uncovered a noise very similar to typical jet engines. These new research fin...

Green skies: Engineer's work may reduce jet travel's role in global warming

Princeton Professor of Mechanical and Aerospace Engineering Fred Dryer has a lofty goal: end the nation's reliance on oil for jet travel. With potentially major benefits for energy security and the environment riding upon his success, Dryer is advancing the fundamental knowledge of jet fuels w...

Travelers can avoid jet lag by resetting their body clocks

A simple, at-home treatment -- a single light box and the over-the-counter drug melatonin -- allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones, according to new research being published in The Endocrine Society's Journal of Clinical Endocri...

New understanding of jet lag

A new study demonstrates that the brain's central timekeeper - the biological clock that regulates waking and sleeping cycles - has two parts that fall out of synchrony during light schedule shifts of six hours, the time it takes to fly across the Atlantic. The finding may explain, at least in pa...
