Clothes That Kill
StriderA writes "Robert Engel, of Queens College at The City University of New York, and colleagues have developed a new defence against bacteria and fungi. It seems that they have created tiny molecular daggers that actually seek and destroy the fatty bacteria. Applications to include battling athletes foot to military uniforms that kill anthrax."
As the sibling to your message pointed out, in order to resist this, bacteria need to give up their fatty exteriors altogether. This is not going to happen. If it did, it would become a bacteria that could not survive in the real world and would pose no threat to us anyhow.
Life is quite resilient, but it's not magical. Adaptability has limits.
