This is Scientific American - 60 second Science. I'm Christopher Antaryata. Got a minute? We humans take medicine when we are sick.

Take fruit flies, which sip 6 alcohol to ward 7 off parasitic 8 wasps 9, or willias, which lie no nest with anti-fungal anti-bacteria tree sap. Now researchers in Finland report that ants there that have encountered pathogenic fungus 10 appeared to fight the infection by eating foods high in free radicals 11. Those are molecules 12 with a talent for causing cell damage, in this case, to the cells of the fungus, as according to a study in the journal Evolution. The researchers collected some 400 wild ants, exposed some to the fungus and left the rest alone. Then they offered up a sort of aggie 13 custered, either plane or laced with free radicals in the form of hydrogen peroxide. Uninfected ants didn’t want anything to do with radical-rich food, which makes sense. “Is that clear mean we don’t need pain-killers on a daily basis, or we don’t take anti- …” …
