Collisions between gold nuclei at the Relativistic Heavy Ion Collider (RHIC) on Long Island, New York, have yielded heavy isotopes of antihydrogen that include a subatomic particle known as an antistrange quark, which is heavier than less unusual up or down quarks.

However, the most striking observation came while running a control experiment in which they replaced the reducing agent — which ordinarily releases the gold particles — with microdroplets of water.

Unlike most accelerators, which smash together simple particles like individual protons, RHIC accelerates clusters of hundreds of gold atoms — with 79 protons and neutrons in each gold nucleus — to 99.99 percent the speed of light.

The basic idea is that, in the case of large nuclei such as gold, which have a very large positive electric charge, electromagnetic interactions play a much more important role in particle production than they do in the case when two small, equally charged protons collide.

The particles don't carry any drugs, but the tiny gold rods readily absorb laser light, which heats them up and kills surrounding tissue.
