where he simply stated “there’s not a hell of a lot we can do about it at the moment,” which is true. We don’t have any real deflection or evacuation plan to speak of, though those efforts are in the early stages (and have been for a while).
Nuth’s solution? He’d like to see NASA build an “intercepting spacecraft” designed to (you guessed it) intercept a potential asteroid and blow it off its collision course. He also recommended a scout craft that could also be launched toward the asteroid to help the larger craft with its accuracy. Since, you know, the fate of the world would be at stake and all. Though there is no imminent threat (that we know about), Nuth said NASA should make this a priority right now so the craft could be ready to launch in the event of a disaster.
If we wait until the threat is known, Nuth said it would almost certainly be too late.
During the larval stage, the glowworms create a nest, first by making a mucous tube that measures up to 16 inches (40 centimeters) long, which is where the glowing larva resides, and then by suspending a curtain of sticky threads — some as long as 20 inches (50 cm) — from it, von Byern said.
These sticky threads catch flying insects — such as moths, mayflies and sand flies — and crawling critters, including ants and millipedes, and even small land snails, von Byern said. Once the prey is trapped in the sticky silk, the glowworm hauls up the thread with its mouthparts, chows down on the meal and tidies up its nest, keeping the fishing lines clean for future prey.
In the past, researchers assumed that glowworms used oxalic acid (a chemical often found in plants such as spinach leaves) to poison their prey, but past research proved that idea wrong, von Byern said. Rather than poison their prey, the larvae trap it.
