There are 4,500 known species of cockroach that live in a number of different environments all over the world. Sure, cockroaches that scurry around your kitchen are pretty gross and there is no real reason you shouldn’t just put your foot down on those little guys—but there are actually only four species of cockroach that are considered to really be pests. The other 4,496 species are about as diverse as you might expect, and have yielded some pretty useful applications for the scientific community.
All grossness aside, this photo-heavy spread in BBC Magazine looks at some of the most useful contributions that the biology of the cockroach has yet to make to humanity. As it turns out, the next generation of prosthetics will likely be based in part on the flexibility and springiness that is unique to roach legs—in particular, the mechanics of a roach leg may help researchers develop prosthetic hands that are more capable to gripping objects in the same way a human hand would.
Then there are the cybernetic roaches—live cockroaches implanted with miniature computers—that may be remotely operated to access places that would otherwise be difficult for people to access—think natural disaster areas. In fact, students from Shanghai Jiap Tong University have even gone so far as to demonstrate how human brain waves could be translated into electrical impulses that control one of these robo-roaches.
Perhaps one of the most promising areas of cockroach-inspired research—though it is not exactly new—is focused on the cockroach’s ability to synthesize relatively powerful antibiotics. It is hoped that this ability may help researchers develop new antibiotics capable of battling some of the most virulent bacteria known to humankind, including MRSA and E. coli.
Though it may be little consolation to you next time you surprise a cockroach that is roaming your countertops, you can rest assured that—somewhere and somehow—roaches may just end up making all our lives a little bit easier.
