ScienceNOW:
Of all the radioactive isotopes left over from nuclear weapons
testing and nuclear power plants, cesium-137 is among the most
dangerous. The soft, silvery-white metal has a half-life of 30
years, enters the body quickly, and can trigger cancer even
decades after exposure. Removing cesium-137 from the
environment has proven difficult, but researchers say they have
a promising new way to clean it up: a flexible, porous solid
that grabs cesium ions much like a Venus flytrap ensnares its
prey.
