Here's a story that combines two favorite bits of volcano news into one interesting discovery. You know those great, freaky photos of volcanic lightning? (In case you don't, I've got one posted above.) Remember how the Icelandic volcanic eruptions totally screwed up everybody's airplane travel plans?
Apparently, studying volcanic lightning could lead to better eruption detection systems that could make it easier to predict how big a plume of ash off that volcano will be—knowledge that can help airlines and travelers be better prepared. At Nature, Richard Monastersky reports:
The researchers found that the amount of lightning correlated with the height of the plume, something they could not test using more limited data collected during an eruption at Alaska’s Mount St Augustine in 2006. This observation is important, says Behnke, because systems to monitor lightning could provide an estimate for the size of an eruption, which is not always easy to assess for remote volcanoes.
During a previous eruption at Mount Redoubt in 1989 and 1990, for example, the size of the plume wasn’t known and a plane nearly crashed after passing through the ash cloud and temporarily losing all power from its engines. Behnke and her colleagues suggest that VHF stations similar to the ones they installed at Mount Redoubt could be used to monitor volcanoes to give early warning of an eruption and an estimate of its size.

Beatboxer Tom Thum had ENT doctor and laryngeal surgeon Dr Matthew Broadhurst shine an endoscopic camera down his throat while beatboxing: “I wanted to find out how my larynx functioned when beatboxing compared to how it functions normally with speech, and whether or not there were any abnormalities in my laryngeal anatomy. I also had […]
Gastric bypass surgery is remarkably effective at promoting weight-loss (it cuts the long-term risk of early death from morbid obesity by 40%), and it’s long been presumed that the major action by which it worked was that, by bypassing the parts of the gut where most food absorbtion takes place, it limited the calories that […]

While some people still maintain that everything in Apple’s walled garden “just works” and is immune to the rampant malware of the Windows world, the reality is different. The Mac’s growing market share has made it a much more viable target for malicious actors, and its built-in tools aren’t always enough to fix things. Drive […]
