The summary isn't detailed enough to bring this up, but TFA tries to equate supersymmetry with dark matter, which is emphatically wrong. The existence of dark matter is strongly supported by astronomical evidence including galaxy rotation velocities and observations of gravitational lensing, regardless of the nature of the particles that make it up. Even if this result provides evidence against supersymmetry (which doesn't seem to be the conclusion of other articles I've read, although I'm not really qualified to say), it tells us absolutely nothing about dark matter.
