Wo eine Operation nicht ausreicht, können verschiedene Arten von Strahlung etwa Tumore bekämpfen.

For nearly one in five wine lovers, a single glass of red wine initiates a painful countdown toward a pulsing headache. This phenomenon has baffled drinkers and scientists alike for centuries, often leaving silkier, high-end Cabernets to trigger migraines while cheaper spirits leave the same drinkers unscathed. While theories have long pointed to sulfites or histamines, recent scientific breakthroughs have spotlighted a new culprit: a flavonol called quercetin. Produced by grapevines as a natural sunscreen in response to sunlight, quercetin is highly beneficial as an antioxidant, but it ...

When most people picture a crime scene, they imagine yellow police tape and obvious danger. But environmental contamination rarely announces itself, and that’s the chilling frame for this true crime science story from Washington Bottom, West Virginia. The Ohio River Valley is steeped in folklore, cryptids, UFOs, alien sightings, and Appalachian rules for surviving the dark, yet the real threat here isn’t a cryptid. It’s industrial pollution that seeps into creeks and wells and into bodies. Killer Chemistry connects that unease to a modern reality: PFAS contamination can turn ordinary ...

Chemistry is a very important and interesting subject, but I feel that in general it is not well taught in schools and colleges.
