What exactly are the “preservatives” we find in our food? Are they poison? Magic? Natural? Safe? This week we take a look at the various methods in which we keep our foods fresh and disease free (which inexplicably involves both Napoleon and ionizing radiation). Plus: The Unipiper talks Nintendo Switch and Grimm, Google Deep Learning predicts cancer, DNA file storage, classic arcade games lose CRTs, New Mexico always on DST, typo causes Amazon outage, Musk sends men around moon, perils of space travel, a cat purr generator, and just how much pee *is* in your pool, anyway? Enjoy!
