An international group of researchers discovered that milk-like protein crystals produced by Diploptera punctata cockroaches are an excellent source of calories and nutrition. That could be good news for scientists working out how to feed a hungry planet, but gross news for anybody who's squeamish about cockroaches.
The bug's common name is the Pacific beetle cockroach, and it's the only one known to bear live young. The mother roach produces the protein crystals to feed the embryos in the brood sac. Just don't expect farmers to open up vast new cockroach ranches where cockroach-pokes rope, wrangle and milk the insects.
Scientists sequenced the genes for the milk protein to reproduce the substance in a lab. "The crystals are like a complete food -- they have proteins, fats and sugars. If you look into the protein sequences, they have all the essential amino acids," researcher Sanchari Banerjee told the Times of India.
Should the cockroach-inspired protein crystals ever make it to the consumer food market, the manufacturer will have a bit of a PR nightmare to overcome. "Cockroach milk...it does a body good" just doesn't quite sound right.
