Half a century of pop science is wrong. It's the wanting molecule. Once you understand the difference, addiction and TikTok stop being mysteries.Wed, 01 Jul 2026 00:00:00 GMThttps://molmotion.com/stories/06-insulin-one-dollar-patent/https://molmotion.com/stories/06-insulin-one-dollar-patent/Before 1922, a child with type-1 diabetes had a life expectancy measured in months. After 1922, that life became 60 years longer. The molecule responsible was discovered by a surgeon who'd never run a lab — and its patent was sold for a single dollar.Wed, 01 Jul 2026 00:00:00 GMThttps://molmotion.com/stories/05-aspirin-bark-to-bayer/https://molmotion.com/stories/05-aspirin-bark-to-bayer/Hippocrates chewed willow bark for fever. 2300 years later, a chemist at Bayer added a two-carbon acetyl group to the active ingredient.
