MTS64 - Martin Blaser - Save Our Endangered Germs In this podcast, I speak to Martin Blaser, Frederick H. King Professor of Internal Medicine and Chairman of the Department of Medicine and Professor of Microbiology at the New York School of Medicine. Blaser studies Helicobacter pylori, bacteria that live in the stomachs of billions of people. Blaser has shown that H. pylori has a strange double life inside of us. On the one hand, it can cause ulcers and gastric cancer. On the other hand, it can protect us from diseases of the esophagus, al ...

In this podcast, I talk to microbe-electricity expert Jeff Gralnick of the University of Minnesota about the biology behind these currents, and how engineers may be able to harness it to power technology.

We live in an invisible ocean of life, with millions of microbes swarming around us. Microbes can live many miles high in the upper atmosphere, and they may actually be able to feed and grow in clouds. Green and I talk not just about high-altitude aerobiology, but about the microbes we share our homes and offices with, and how better understanding them ...

Just as we are home to a vast number of microbes, coral reefs depend on their own invisible menagerie of algae and bacteria to get food, recycle waste, and fend off invaders.
