People have been getting rid of cockroaches for decades by setting out bait mixed with poison. But in the late 1980s, in an apartment test kitchen in Florida, something went very wrong.
A killer product stopped working. Cockroach populations there kept rising. Mystified researchers tested and discarded theory after theory until they finally hit on the explanation: In a remarkably rapid display of evolution at work, many of the cockroaches had lost their sweet tooth, rejecting the corn syrup meant to attract them.
Scientists out of the University of Exeter are implying that smelling farts could actually prevent cancer, among other diseases.
"Although hydrogen sulfide gas"—produced when bacteria breaks down food—"is well known as a pungent, foul-smelling gas in rotten eggs and flatulence, it is naturally produced in the body and could in fact be a healthcare hero with significant implications for future therapies for a variety of diseases," Dr. Mark Wood said in a university release.
Although the stinky gas can be noxious in large doses, scientists believe that a whiff here and there has the power to reduce risks of cancer, strokes, heart attacks, arthritis, and dementia by preserving mitochondria.
