Recognitions, December 11
There’s been a lot to celebrate lately! A UT alumna was named a 2020 Rhodes Scholar—UT’s ninth; another student won UT’s very first Mitchell Scholarship; four faculty members received NSF Early Career awards; two faculty were named AAAS fellows; a UT professor is among the most highly cited researchers; the Haslam College of Business MBA program ranked 50th in the nation; two English professors received recognition for their work; and a former Earth and Planetary Sciences professor was posthumously honored with a special journal issue.
Nature Prefers Asymmetrical Pollen Grains, Study Finds
It’s no secret that pollen plays a vital role in plant reproduction worldwide, including the production of food. But for decades, scientists have been puzzled about the variety of patterns on the surface of these pollen grains—specifically, how they are formed and if they have a function.
A study published in Cell sheds some light on the subject, showing that plants favor the production of uneven, asymmetrical patterns on the surface of pollen grains over more symmetrical patterns.
“The pollen wall itself—the surface of a pollen grain—serves the important function of protecting the pollen grain genetic material from the environment as the pollen travels during the process of pollination. However, the function of the precise pattern on this surface is not well understood,” said Maxim Lavrentovich, assistant professor of theoretical biophysics in the Department of Physics and Astronomy at UT, and coauthor of the study.

NSF Picks UT-ORNL Governor’s Chair for Biodiversity Project
The National Science Foundation recently announced support for a variety of studies aimed at understanding Earth’s biodiversity, including a project led by UT’s Frank Loeffler.
Loeffler, the joint UT–Oak Ridge National Laboratory Governor’s Chair for Microbiology and Civil and Environmental Engineering, is researching the role of microbes in controlling emissions of nitrous oxide—also known as laughing gas—from the ground.
“As nitrous oxide destroys the ozone layer and is a greenhouse gas, gaining a better understanding of how it is released naturally and its overall effect on the environment would be a step toward better controlling it,” said Loeffler, who holds UT appointments in the Department of Microbiology in the College of Arts and Sciences and in the Department of Civil and Environmental Engineering in the Tickle College of Engineering, as well as an adjunct appointment in UT’s Department of Biosystems Engineering and Soil Science and an appointment in ORNL’s Biosciences Division.
