Food Holograms, Self-Decapitating Slugs, Smog Diamonds and Earth's Magnetic Field Flips

Dr Ciaccio (not a doctor) looks into new evidence from New Zealand about the last time the Earth's magnetic poles flipped around 42,000 years ago. Also a promising new technology can etch holograms onto foods, Slugs shed their heads (rather bodies) to get a fresh start and how diamonds made from the carbon in the atmosphere could be a climate boon.
