Crisis. Entropy. Extinction. This year we look at the high stakes for all life on Earth and beyond. Between nuclear proliferation, species loss and dwindling resources, existence itself is not assured. But for every dystopia, a corresponding utopia may be within reach. It may be a struggle, but the record of all life is that of an eon-spanning fight to stay alive. We'll feature tumultuous natural history and startling feats of adaptation. Apoptosis versus immortal cell lines. Half-lives and radical life extension. The deaths of stars and extraordinary paths to SURVIVAL.
