Periodic Table of Death and Mystery

Gather round for a true story about a periodic table element and a Renaissance woman who forged her own story in oil paint. Antimony links directly to Artemisia Gentileschi’s genius—a determined, fiercely talented artist who built a career when women painters were rare and easily erased. She endured a brutal early trauma, yet traveled across Italy, worked for a king and queen in England, and kept painting on her own terms. And she reminds us that our modern lens must not flatten a life well lived, or mar her resilience and the remarkable scope of her work.

Have you ever stupidly accepted a challenge, because in the back of your smug little mind you’re thinking, I’m pretty smart/strong/in shape/brave/unafraid/ and I can Google it? That’s how we got here today, folks, with the periodic table element, xenon, because this noble gas element played a significant role in the chain of events that led to a nuclear disaster—suckered by a physicist casually shelling and eating peanuts and talking about xenon poisoning and xenon pits.

The periodic table element Manganese helps power everything from photosynthesis to batteries. But now it’s at the center of a scientific curfuffle called “dark oxygen.” We’ll follow the backlash from abyssal polymetallic nodules, to a splashy Nature paper, to mining companies with billions on the line—and the microbes that might upend the whole story. Is manganese and dark oxygen a revolution in Earth’s oxygen story or the next cold fusion?

A metal that hardens steel and drives our batteries might also be powering “dark oxygen” in the abyssal depths of the ocean? Or is it …? Let’s dive into manganese, polymetallic nodules, and a paradigm-shifting claim that the seafloor is secretly making its own air, which could change everything we know about how life on Earth started and give us a glimpse into possible life on even the darkest planets in the Universe.

Zirconium is a silvery, heat‑resistant metal, first identified as an element in 1789 and later prized for use in nuclear reactors, turbines, and spacecraft. Today, its ceramic form—zirconium dioxide, or zirconia—is used to make strong, tooth‑colored dental implants instead of hippo ivory or human “Waterloo teeth,” a twist on this 250th Independence Day George Washington could never have imagined. So, from Washington’s dentures and battlefield tooth markets to modern zirconia implants, listen to how zirconium reshaped the story of false teeth on this episode of the Periodic Table of Death and Mystery.
