Why do volcanic ash plumes wreak havoc in the jet stream? Researchers have found that “the jet stream essentially stops the plume from rising higher into the atmosphere,” says volcanologist Marcus Bursik. “Because the jet stream causes the density of the plume to drop so fast, the plume’s ability to rise above the jet stream is halted: the jet stream caps the plume at a certain atmospheric level.” (Credit: Jet Stream/Flickr)

Faster than supersonic on ‘spiked’ jet fuel
“The idea of being able to put in a very small quantity and have such a dramatic effect is important,” says lead investigator Ilhan Aksay about adding nanocatalysts to jet fuel to improve performance.
