Scientists find previously unknown jumping behavior in insects
The previously unrecorded behavior occurs in the larvae of a species of lined flat bark beetle . Specifically, the larvae are able to spring into the air, with each larva curling itself into a loop as it leaps forward. What makes these leaps unique is how the larvae are able to pull it off.
While there are other insect species that are capable of making prodigious leaps, they rely on something called a"latch-mediated spring actuation mechanism." This means that they essentially have two parts of their body latch onto each other while the insect exerts force, building up a significant amount of energy. The insect then unlatches the two parts, releasing all of that energy at once, allowing it to spring off the ground.
"The way these larvae were jumping was impressive at first, but we didn't immediately understand how unique it was," Bertone says."We then shared it with a number of beetle experts around the country, and none of them had seen the jumping behavior before. That's when we realized we needed to take a closer look at just how the larvae was doing what it was doing.

Hubble finds a black hole igniting star formation in a dwarf galaxy -- ScienceDailyOften portrayed as destructive monsters that hold light captive, black holes take on a less villainous role in the latest research from NASA's Hubble Space Telescope. A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up. The black hole is apparently contributing to the firestorm of new star formation taking place in the galaxy. The dwarf galaxy lies 30 million light-years away, in the southern constellation Pyxis.
