A bread recipe from 14,000 years ago: wild oats, barley, wheat and roots. Your car might be trying to kill you by lulling you with sleep-inducing vibrations. The science behind 'Ant-man' - Did they really just put 'quantum' in front of everything? Migrating geese are losing the race north - and their chicks are paying the price. Diving a kilometre down and not getting 'the bends' - how dolphins do it. New moons of Jupiter came from a demolition derby, and it's not over yet. The reason why most animals are symmetrical has to do with their locomotion

Conventional wisdom has it that the human dependence on grains for most of our calories came after agriculture started, perhaps 12k years ago. But research shows that baked bread goes WAY back in history before signs of agriculture. Fascinating.
