insects

A new coating turns insects' sticky climbing feet into a slippery mess, and could be the future of pest repellent, according to a new research paper. You hear that, bugs? If you can't crawl up my kitchen counter from the floor, you can't go waving your disgusting antennae all over my pizza, you insects-who-shall-not-be-named of apartment horror.

In January, researchers from the University of California, Berkeley, told a stunned conference audience that they had managed to create a remote-controlled cyborg beetle by attaching a computer chip to the brain of a giant insect. Now, the paper explaining how they did it has been published in the journal Frontiers In Neuroscience, and they have released a video of the cyber-bug in action.

What do you do when you're under attack? Call for help, naturally. Unfortunately, if you're an ear of corn, and you're being attacked by parasitic beetle larvae, you have nothing to call for help with. Until now.

Scientists at the University of Missouri have genetically modified corn to release a chemical distress signal when under attack from beetle larvae. The chemical 911 call attracts droves of parastitic roundworms that naturally attack the larvae. Within three days of receiving the distress signal, the worms had killed them all.

Flies may not seem like nature's ace pilots when they're bumping up against a closed window or getting squashed beneath a rolled-up copy of the New York Times Magazine, but a German company hopes to unravel the secrets of insect flight by tapping their brains. Literally.

In its attempts to quash weapons of mass destruction, the Pentagon has been trying novel ways to track down dangerous materiel. For years, DARPA has been trying to train insects and bugs to sniff out toxic substances, providing more sensitive detection, as well as access that conventional sensors might not have.

As a respite from the nonstop flu blogging, I decided it was time to have a little fun and show the lighter side of science.

First up is a story from the Wall Street Journal about the residents of Tuscarora, Nevada, driving off a swarm of insects by blasting Led Zeppelin.

The incidence of asthma and allergies are on the rise. In the United States alone, asthma rates have doubled since the 1980s. And, according to a recent article by the BBC, doctors once estimated 15 percent of the population had some type of allergy, but now believe the figure is closer to 40. More patients are also suffering from multiple allergies than ever before. The reason for this trend has been widely disputed, but a new study points the finger at a surprising culprit: lice.
