(Inside Science) -- Xenon is one of the so-called noble gases. It's odorless, colorless and a loner. It very rarely combines with other atoms, or even itself, to form molecules. Like helium, neon, argon, krypton and radon, it's kind of a wallflower that rests on the far right of the periodic table.
Unlike most of those others, though, recent reports show that xenon might improve athletic performance in endurance sports. The gas may also help erase traumatic memories.
