Antibiotics in cockroach brains may lead to new bacteria-killing drugs. Harmful bacteria have become increasingly resistant to antibiotics, so scientists have been looking to nature for alternatives. The fact that cockroaches often thrive in unhygienic environments led researchers to discover naturally produced antibacterial molecules in cockroaches.
These molecules that are found in the brains of these insects can potentially kill deadly bacteria like MRSA and E. coli. Experiments revealed that antibiotics in cockroach brains are effective and non-toxic to humans.
