“As an instructor, I try to teach how the topic has relevance from different approaches in biology,” said Erik Herzog, Professor of Biology at Washington University in St. Louis. Herzog teaches undergraduate biology courses at the university. His lab uses a variety of techniques to study the cellular and molecular basis of circadian rhythms, biological clocks that drive near 24-hour rhythms in living beings including animals and plants.

In a new publication in the journal Nature Plants, researchers [led by Richard Vierstra] in Arts & Sciences describe the effects of autophagy on metabolism in maize, commonly known as corn, an important crop that is sensitive to nitrogen deprivation.

How does evolution select the fittest “individuals” when they are ecosystems made up of hosts and their microbiomes? Joan Strassmann and other biologists debate the need to revise theories.

The American Association for the Advancement of Science has bestowed upon 416 of its members the lifetime honor of being an elected Fellow in recognition of their extraordinary achievements in advancing science. . .This year’s Fellows, who represent a broad swath of scientific disciplines, were selected for diverse accomplishments that include pioneering research, leadership within their field, teaching and mentoring, fostering collaborations and advancing public understanding of science.

Researchers from Washington University in St. Louis have mapped the regions of the brain in mormyrid fish in extremely high detail. In a new study published in the Nov. 15 issue of Current Biology, they report that the part of the brain called the cerebellum is bigger in members of this fish family compared to related fish — and this may be associated with their use of weak electric discharges to locate prey and to communicate with one another.

How does sensory processing lend itself to life as we know it? If our experiences materialize due to sensory transduction, do these processes inspire our entire perspective? These questions sparked Mary Lambo’s interest in neuroscience and eventually motivated her research in neural plasticity and sensory processing. As new teaching faculty at Wash U, Mary now guides students through fundamental neuroscience concepts and challenges them to discover their own motivating questions.

How predictable is evolution? The answer long has been debated by biologists grappling with the extent to which history affects the repeatability of evolution. A review published in the Nov. 9 issue of Science explores the complexity of evolution’s predictability in extraordinary detail. In it, researchers from Kenyon College, Michigan State University and Washington University in St. Louis closely examine evidence from a number of empirical studies of evolutionary repeatability and contingency in an effort to fully interrogate ideas about contingency’s role in evolution.

Most of the country switched their clocks back an hour over the weekend, ending daylight saving time. And even though one hour might not sound like a lot, it has a noticeable impact. "In the long term, this one hour cumulatively can really have effects on our health," says Erik Herzog, professor of biology and neuroscience at Washington University in St. Louis.

Richard D. Vierstra, the George and Charmaine Mallinckrodt Professor in the Department of Biology in Arts & Sciences, received a $304,000 grant from the National Institutes of Health (NIH) for a project titled “Phytochromes: Structural perspectives on photoactivation and signaling.” Vierstra was also granted $49,000 from the NIH to study autophagic clearance of inactive proteasomes and ribosomes as models for protein quality control.

David L. Kirk, professor emeritus of biology in Arts & Sciences at Washington University in St. Louis, died Thursday, Nov. 1, 2018, at Dougherty Ferry Assisted Living in St. Louis after a long illness. He was 84. Kirk, who was an active and passionate member of the university community for nearly 50 years, spent a lifetime teaching developmental biology and researching the evolutionary origins of multicellular organisms. He was internationally known for his research on the spherical green alga known as Volvox carteri.

Himadri Pakrasi, the Myron and Sonya Glassberg/Albert and Blanche Greensfelder Distinguished University Professor in the Department of Biology, received a $1.5 million award from the U.S. Department of Energy to develop Anabaena 33047 — a photosynthetic, fast-growing, nitrogen-fixing cyanobacteria — as a versatile production platform that can be used by the bioenergy research community.

Next Generation Leaders are selected each year through a competitive process that includes applications from around the world. This year, the six Next Generation Leaders come from universities and research institutes in the U.S., Canada and Germany. They will each have a three-year term on the advisory council.

“The Society is proud to present Dr. Herzog and Dr. Peker with this year’s award,” said SfN President Richard Huganir. “Dr. Herzog is a gifted teacher and science communicator who is committed to increasing diversity through mentoring, while Dr. Peker has been instrumental in demonstrating the benefits of international educational experiences and research collaborations.”

Can electricity serve as an alternative electron supplier for bacterial growth? And can we enhance the electron uptake capacity of bacteria?

Living Earth Collaborative grant supports efforts to understand if Peter's Angola colobus monkeys represent one or two subspecies

Joseph Jez began his work with the Biology Department ten years ago as an assistant professor. He is now Professor of Biology, Howard Hughes Medical Institute Professor and as of July 1, 2018 the Biology Department Chair. We sat down to talk about the changes he’s witnessed over the last decade as well as what he would like to see in the future.

A new study in the journal Scientific Reports gets to the bottom of it: Why do dogs that are trained to locate poop sometimes find the wrong kind of poop?

Li also collaborated with Erik Herzog, professor of biology in Arts & Sciences at Washington University who studies the cellular and molecular basis of circadian rhythms in mammals

Improbable Destinies: Fate, Chance and the Future of Evolution

A&S professor awarded $2 million for research that could help defeat antibiotic-resistant infections

A $762k collaborative NSF grant will fund a partnership between Joseph Jez (Wash U Biology chair) with Hiroshi Maeda (U Wisconsin-Madison; Botany) on the mechanisms and impacts of de-regulating aromatic amino acid biosynthesis in plants.

An immediate before-after comparison — the first of its kind — shows that survivors of a hurricane have different traits than the general population.

Joan Strassmann and David Queller were awarded a $1,139,388 National Science Foundation grant for the four-year project "Kith and kin in amoeba-bacteria cooperation", about the evolution of cooperation both within and between species, using an amoeba-bacteria system.

The two year grant was awarded from the National Science Foundation

Next step could be ‘nitrogen-fixing’ plants that can do the same, reducing need for fertilizer.

“We train our students to do any type of science. We want to give them the tools so that whether they go into industry, academia or government, they will benefit from what they learned in graduate school,” said Dixit.

Warmer active seasons and fewer freeze-thaw events lead to big changes for the tiniest Arctic ambassadors — its arthropods.

Nowadays Sally Elgin would probably be referred to as gifted or talented. But in the 1950s, a really smart girl was obnoxious or a nerd.

In the midst of what scientists consider to be a sixth mass extinction event, Washington University is joining forces with the Missouri Botanical Garden and the Saint Louis Zoo to collaborate on ­ life-saving research and conservation efforts.
