"giANTS" is a 1979 science fiction short story by Edward Bryant. It was first published in Analog Science Fiction.[1]
An elderly scientist explains why he hates ants, and why he is participating in a secret government project to increase the size of invasive ants. He explains that the "square-cube law" demands that an ever-increasingly size-mutated ant will at some point collapse under its own mass. The square-cube law and forced mutation is used to thwart a South American giant ant invasion.
"giANTS" won the Nebula Award for Best Short Story of 1979,[2] and was nominated for the 1980 Hugo Award for Best Short Story.[3] Gary Westfahl has noted that the story is based on the fact that giant insects "would be unable to walk or sustain themselves".[4]
