Department of Biology
The Department of Biology offers exceptional opportunities to learn, work, and collaborate across levels of biological organization and styles of research. Faculty research interests span the complete spectrum of biological phenomena and disciplines, from biochemistry to global environmental change. This breadth of research interests has led to development of three focused, yet overlapping, graduate training programs: Molecular, Cellular, and Evolutionary Biology (MCEB), Ecology Evolution and Organismal Biology (EEOB), and Microbial Biology.

Why Bad Immunity Genes Survive
Feb. 6, 2012 – University of Utah biologists found new evidence why mice, people and other vertebrate animals carry thousands of varieties of genes to make immune-system proteins named MHCs – even though some of those genes make us susceptible to infections and to autoimmune diseases. “Major histocompatibility complex” (MHC) proteins are found on the surface of most cells in vertebrate animals. They distinguish self from foreign, and trigger an immune response against foreign invaders. MHCs recognize invading germs, reject or accept transplanted organs and play a role in helping us smell compatible mates. “This study explains why there are so many versions of the MHC genes, and why the ones that cause susceptibility to diseases are being maintained and not eliminated,” says biology Professor Wayne Potts. “They are involved in a never-ending arms race that causes them, at any point in time, to be good against some infections but bad against other infections and autoimmune diseases.” See full story...
Birds of a Feather Don’t Always Stick Together
Jan. 19, 2012 – Pigeons display spectacular variations in their feathers, feet, beaks and other physical traits, but a new University of Utah study shows that visible traits don’t always coincide with genetics: A bird from one breed may have huge foot feathers, while a closely related breed does not; yet two unrelated pigeon breeds both may have large foot feathers “Most people think of pigeons as rats of the sky, but in fact they’re really incredibly diverse,” says Michael Shapiro, an assistant professor of biology and senior author of the study published online Jan. 19 in the journal Current Biology.
