Scientists Have Worked Out Why Cockroaches Are Basically Invincible

Cockroaches are observed all over the place with apparently few problems. And now a squad of Chinese scientists say they have worked out what makes them so hardy.

The researchers, led by Sheng Li from South China Normal University in Guangzhou, sequenced the Dna of the American cockroach ( Periplaneta Americana ), which it’s safe to say isn’t too popular.

They found that it had an expanded decide of genes that enables it to sense reeks from food, particularly fermented food, according to The Guardian. They also have an internal detoxification system to safeguard against feeing anything toxic, and a powerful immune system.

“Our genomic and functional analysis in the American cockroach provided insights into its success in the adaptation to urban environments and the biology, ” they write in their newspaper, published in Nature Communications.

The American cockroach is procured throughout the US, having been introduced from Africa in the 17 th century. They grow to a few centimeters in length, have wings, and are generally simply all around nasty. I have had one fly at my head before. Yes, it was terrible.

Cockroaches are also known for their seem invulnerability, though, hence why they are found in all sorts of places. This is in part due to its aforementioned abilities, but also that they reproduce unbelievably rapidly. There’s even the myth that they can outlast a nuclear armageddon, although that’s probably not true.

But they are still pretty incredible. According to National Geographic, the beasts were found to contain more than 500 “taste buds”, which allows them to eat a varied diet and adapt to a range of surroundings. And they also have genes that allows them to more easily survive in toxic environments.

Impressively, they also discovered genes that allowed the cockroaches to regrow legs. The team noted in their newspaper that when two specific genes were depleted, the regeneration of limbs was “completely prohibited”.

“We are currently investigating whether there is a’ growth factor’ connecting leg regeneration in the American cockroach to its ethanol extract that is used for wound healing and tissue repair in humen, ” they said.

Despite its impressive credentials, the American cockroach is still threatened by global warming. So the scientists hope that by analyse this insect, we might do better at controlling its population, as well as learning more about its insect superpowers.

Aside from being a pest, in Chinese medicine the cockroach is considered to have healing powers, and its ethanol extract has also been used as a drug for meander healing and tissue repair. So it’s not all bad.
