Molecular ruler sets bacterial needle length

New understanding of how bacteria determine the correct length of injectosomes

Disease bacteria, including the bubonic plague and salmonella, use needle-like "injectosomes" to inject proteins into healthy cells. Now, U Biology Professor Kelly Hughes and doctoral student Daniel Wee have determined that bacteria have a specific mechanism to make sure these needles are neither too long nor too short. This finding has significant implications for disease treatment and nanomachines, Hughes and Wee say.

Early herders' grassy route through Africa

New Evidence on Early Human Migration in Africa

Scientists long knew that humans migrated from northern Africa south past Lake Victoria; they just didn't know when or by what route.  Studying the ecology and animal teeth in the Lake Victoria region, U paleoecologist Kendra Chritz and her team have now shown that this migration took place nearly 2,000 years ago, giving new insight into the transition from hunter-gatherer to agricultural society.

Cottrell Scholar Award for Chemist Jennifer Heemstra

Jennifer Heemstra, Assistant Professor of Chemistry

Jennifer Heemstra, Assistant Professor of Chemistry, has been awarded a Cottrell Scholar Award, which honors faculty committed to excellence in research and undergraduate teaching. Dr. Heemstra will use this award to study new methods of labeling RNA in cells, and to prepare undergraduates in her Advanced Chemical Biology Lab course.

Mathematician Wins Prestigious Research Award

Jonathan Chaika, ASsociate Professor of Mathematics

Math Professor Jonathan Chaika received the prestigious 2015 Sloan Research Fellowship. Chaika's expertise is in the field known as ergodic theory, which studies the ways that points travel through space and time. Each year, the Sloan Research Fellowship recognizes the next generation of scientific leaders in the United States and Canada, and we congratulate Dr. Chaika on this prestigious award!

U Undergrads Study Wildlife With Camera Traps

Red Butte Moose

Mountain lions, moose and bears, oh my! In the University of Utah’s own backyard lies Red Butte Canyon, the most pristine ecosystem along Utah’s Wasatch Front filled with a variety of wildlife species. Managed by the U.S. Forest Service and designated as a Research Natural Area, Red Butte is restricted to all except those who use the area for scientific studies. Members of the U’s Biodiversity and Conservation Ecology Lab are some of those who have exclusive access to study the area and the animals in it.
