The United States uses locusts as explosive detectors

This year, 2020 is a really disastrous year. The outbreak of coronavirus pneumonia in China, the mountain fire in Australia in the southern hemisphere for several months, the outbreak of influenza in the United States, and the locust disaster in Africa, India, Pakistan and other places. Recently, American scientists have opened their brains and developed semi-mechanical locusts to act as explosive detectors for explosive detection.


It is understood that since December last year, there have been large-scale locust disasters in East Africa and South Asia. Countries such as Kenya, Somalia, Ethiopia, India, Pakistan and so on are all seriously affected countries. The number of locusts has reached a terrifying 360 billion, and it is even more likely that it will soar to 400 billion. Where locusts go, they will be eaten up in 1-2 hours. The locust disaster is really well-known.

Locust disaster, flood disaster and drought disaster are called three natural disasters. Locust has become a hot spot. Locust prevention is the focus of discussion now. Will locust disaster hit Tibet, Yunnan, Guizhou, Sichuan and other places in China?

Domestic readers, considering the locust disaster, are ready to use food to solve the problem. After all, there are 1.4 billion people in China. It's a clear case that crayfish is eaten by domestic products as an alien species. The domestic food army is hungry for food. At the same time, there is an old way 20 years ago to fly ducks and chickens to Xinjiang to eat locusts. Hundreds of thousands of domestic duck and chicken armies are ready to go.

The United States recently learned that locusts are not idle. For the special ability of being sensitive to locusts' smell, the U.S. Navy funded the research on semi mechanical locusts. According to the preview paper published on biorxiv, researchers from Washington University in St. Louis in the United States successfully developed semi mechanical locusts. This research generation of the U.S. Navy funded at least $750000.

There are about 50000 olfactory nerve units in the antennae of locusts, which are very sensitive to the smell of chemicals such as ammonium nitrate, which are usually used to prepare explosives and bombs. Researchers use locusts to make a micro incision in the head and install a micro gear robot. Through modification, semi-mechanical locusts can recognize five kinds of explosive odor or some other chemical substances in 500 milliseconds. However, there are many defects in the transformation. After the electronic chip is implanted for more than 7 hours, the signal receiving ability of the semi-mechanical locust will slowly decrease until it disappears, and the life of the semi-mechanical locust transformed will also be shorter.
