Panic in Level 4: Cannibals, Killer Viruses, and Other Journeys to the Edge of Science

Richard Preston

Richard Preston, bestselling author of *The Hot Zone*, takes us inside the terrifying world of Biosafety Level 4 laboratories in his book *Panic in Level 4: Cannibals, Killer Viruses, and Other Journeys to the Edge of Science*. This isn't just about killer viruses like Ebola and Marburg. It's about the scientists who risk their lives daily, the bizarre mathematics of pi computed to billions of digits by brothers in a Manhattan apartment, and the silent ecological collapse from invasive species. Preston himself once had his protective suit zipper fail completely while inside a Level 4 hot zone—only a stream of positive-pressure air saved him. This video breaks down the most shocking, human, and mind-bending stories from the edge of science, revealing the panic, the obsession, and the fragile line between discovery and disaster.
