MTS38 - Jonathan Eisen - An Embarrassment of Genomes

Jonathan Eisen is a professor at the University of California, Davis Genome Center. Over the course of his career, he has pioneered new ways of sequencing microbial genomes and analyzing them. I talked to Eisen about some of the weirdest creatures he's studied, such as bacteria that only live on the bellies of worms at the bottom of the ocean, and how we may be able to exploit their genomes for our own benefit. We also discussed the new movement for open access to scientific literature, a subje...

MTS37 - Hazel Barton - Cave Dwellers

Hazel Barton is the Ashland Professor of Integrative Science at Northern Kentucky. She explores some of the world's most remote caves to study the remarkable diversity of microbes that thrive in their dark recesses. I spoke to Barton about how she first became captivated by these bizarre organisms, what it's like to do delicate microbiology when you're hip-deep in mud, and why she wants to explore caves on Mars in search of Martians. ...

MTS36 - Dennis Bray - Living Computers

Dennis Bray is an active professor emeritus in both the Department of Physiology and Department of Neuroscience at the University of Cambridge. He studies the behavior of microbes--how they "decide" where to swim, when to divide, and how best to manage the millions of chemical reactions taking place inside their membranes. For Bray, microbes are tiny, living computers, with genes and proteins serving the roles of microprocessors. In this interview, I talked with Bray about his provocative new b...
