Jessica Petersen Associate Professor of Animal Science, with beef cattle in the animal science arena on East Campus. Her research can expand the range of genetic tools used by breeders to boost cattle growth efficiency. An increase in feed efficiency of just 1% would save the U.S. cattle sector more than $11 million a year. September 15, 2023. Photo by Craig Chandler / University Communication.

John DeLong collects water samples from Wildwood Lake northwest of Lincoln. DeLong published the first study investigating and demonstrating the effects of “virovory” – the phenomenon of Halteria eating infectious chloroviruses in an aquatic habitat. The experiments showed, for the first time, that a virus-only diet can fuel physiological growth and even population growth of an organism.
