Cockroaches may be in your future in more ways than their usual icky-yucky-crawly ways. Science News reports that ground-up "brain and other nerve tissues" from cockroaches was found to kill more than a few types of bad bacteria (like a type of E. coli, a meningitis strain and a staph strain.) Of course, this means they are looking at what the substances are, how much will be needed, etc. so they can figure out how to help people with infections.
Figuring that roaches live and thrive in some of the grossest conditions known to man or beast - is it any wonder that science would eventually get around to finding out how they do this?
And... of course, no discussion of brains, especially in this context, could stop me from thinking about this...
