At Meet the Scientist, we want to reveal more about scientists, the work they do, and what makes them tick. We will ask them what they are are up to now and what is next. How is the science moving forward to solve some of the intractable problems of our times? What keeps them going in a tough, competitive field? What do they see for the future of research, education, and training? We hope to show you a glimpse of what scientists are really like and what is going on in cutting-edge research today.
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, allergies, asthma, and perhaps even obesity.
We're now eradicating H. pylori with antibiotics and other luxuries of modern life; Blaser thinks we ought to bring it back--but keep it on a tight leash.
All life hums with electricity, from our heartbeats to the electrons that flow to the oxygen we breathe. But some bacteria are electricians par excellence, generating electric currents in the soil and water.
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.
In this podcast I talk to Jessica Green of the University of Oregon about aerobiology: the science of life in the air.
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 can help our health.
In this podcast, I talk to Charles Bamforth of the University of California, Davis, about the surprisingly complex chemistry of beer, and the pivotal role microbes play in making it happen.
Dr. Bamforth is the Anheuser-Busch Edowed Professor, selected after an international search, specializing in the science of malting and brewing. His current research program focuses primarily on the wholesomeness of beer, including studies on the psychophysics of beer perception, on polyphenols and on the residues from non-starchy polysaccharide digestion that constitute soluble fiber and potential prebiotics in beer. Research in the laboratory also embraces the enzymology of the brewing process, foam stability, preventing oxidation in wort and beer and alternative paradigms for beer production.
In this podcast I talk to Thomas Scott of the University of California, Davis, about dengue fever, a disease that's on the rise.
Spread by mosquitoes, it can make you feel as if your bones are broken and leave you exhausted for months. In more serious cases, people suffer uncontrollable bleeding and sometimes die. Dengue is expanding its range, and is even making incursions into the United States. Scott and I talk about what scientists know and don't know yet about dengue, and what the best strategy will be to drive the virus down.
