We have used a missing mass torsion balance to test the gravitational inverse-square law for length scales well below the dark-energy scale of 85 microns. We find no violations for Yukawa lengths greater than or equal to 56 microns. I will discuss the challenges, techniques, results and particle-physics implications of this work.
