“The volcano has been erupting since 1999, but has been particularly active in the last two months.Tungurahua is one of eight active volcanoes in Ecuador, which lies in the so-called Pacific Ring of Fire.”
The eruption fortunately did no major damage and also created a spectacular ash plume that was estimated to be up to 6 miles high. Check Out some great pictures below of the eruption in action.
Meet the issus planthopper, a close relative of the grasshopper.
In September of last year, scientists studying this insect discovered that the issus was using a built-in mechanical gear to synchronize the powerful jumping mechanisms that it uses to jump distances over 100 times its body-length. Here’s a close up:
It’s the first mechanical gear found within a living creature, and helps the planthopper achieve jumping accelerations up to 400g’s (ie. 400x the force of gravity), 20 times what the human body can withstand.
Here’s a video showing the mechanism in action. It has been slowed waaaay down- the actual process happens in less than 30 milliseconds:
