What happened: Louis Pasteur (Pasteur will be celebrated) is credited with discovering microbial decay (lost thing is discovered, hidden for many centuries).
“这些生物从一个我们从未想到的来源获取能量，”McKay惊叹，“南非的极端微生物细菌吃的是岩石里不稳定原子衰变时的放射能。”
"These creatures get their energy from sources we never imagined," McKay exclaims. "the South African extremophile bacteria are powered by the radioactive decay of unstable atoms in the rocks."
