Searching for Future Cures Deep in Caves - Nicholaus Vieira

Mountain climbers don't need to have an understanding of SCUBA gear; underwater divers don't need to understand how to climb over glaciers with ropes and ice axes. But Nicholaus Vieira, also known by his "Crazy Caver" persona explains that cavers need to be adept at all types of exploration. Vieira tells Boyd that subterranean geography doesn't always reflect what's happening above ground. Conditions can vary wildly, and the only way to find out what's happening deep below the Earth's surface is to find a cave and climb down. Vieira isn't just searching for thrills underground. He's hoping to find new types of microbial life that have been isolated from humans for long enough, that they could potentially treat bacterial infections that are resistant to our current antibiotics.
