A 5,300-year-old murder case - Albert Zink
Get to know the story of Ötzi the Iceman, a 5,300-year-old glacier mummy who researchers discovered had been murdered. -- In September 1991, two hikers discovered a corpse emerging from the ice. Researchers soon realized they were looking at the mummified body of a man who’d lived about 5,300 years ago, and theorized he got caught in bad weather and froze. However, a shocking discovery revealed his true cause of death and upended his story. So, how did he die? Albert Zink uncovers the truth about Özti the Iceman.

Why your phone battery declines over time - George Zaidan
Explore the science of why single-use and rechargeable batteries die, and find out why recycling batteries can be challenging. -- Almost all batteries, even single-use batteries, are theoretically rechargeable. That’s because the metals and other chemicals are still there in the battery. So chemically speaking, a dead battery is actually not that different from a fresh one. Then why do batteries die in the first place? And what should you do with them once they’re spent? George Zaidan digs into the science of batteries.
