Biology Professor Highlights Active Learning in Science Education

| Read Story

“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.

Plant’s recycling system important in sickness and in health

| Read Story

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.

Should Evolution Treat Our Microbes as Part of Us?

| Read Story

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.

International collaboration taking place in Pakrasi lab

| Read Story

Currently, in the depths of the McDonnell Hall basement at Washington University, a PhD student from IITB, Annesha Sengupta, is performing research that could have major global significance in the future. Since April 2018, Sengupta has been learning the CRISPR genome editing technique from scientists in the Pakrasi Lab. Once Sengupta masters this skill, she will then edit the genome of an Indian cyanobacterial isolate for the purpose of creating a platform for biofuel production.

Bio 500 Research Spotlight: Kevin Yin on the Rentschler Lab

| Read Story

In the Rentschler lab, we aim to address heart disease by looking at how developmental pathways and gene regulation networks are associated with various heart diseases. We are specifically interested in how alterations of genes during development or in the adult can lead to arrhythmias such as atrial fibrillation and ventricular tachycardia.

Getting to know the humans of Tyson

| Read Story

As Tyson Humanities Fellows, Kit Lord and Hayley Huntley spent three months at the university's environmental field station, embedding with the Tyson community to explore the human side of science. After conducting hundreds of hours of interviews, the fellows, led by environmental humanities lecturer Suzanne Loui, profiled the people who make Tyson a thriving research ecosystem. Here, Lord details their collaborative interview project, Humans of Tyson.

New maps hint at how electric fish got their big brains

| Read Story

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.

Replaying the tape of life: Is it possible?

| Read Story

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.

Bio 500 Research Spotlight: Benjamin French on the Elgin Lab

| Read Story

I have been working in Dr. Elgin’s lab for the past two and a half years to analyze the characteristics of an unusual chromosome in Drosophila (fruit flies). The fourth chromosome of Drosophila melanogaster is unusual because this tiny chromosome is almost entirely heterochromatic yet contains about 80 protein-coding genes. In the Elgin lab, we use a combination of DNA manipulation experiments done in the wet lab and bioinformatic analyses done on the computer to identify factors that enable the expression of fourth chromosome genes within a mostly heterochromatic domain.

Erik Herzog on Daylight Savings Time

| Read Story

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.

Bio 500 Research Spotlight: Hannah White on the Perlmutter Lab

| Read Story

Joel Perlmutter’s lab has many different projects, most of which are focused on the development of new PET radiotracers for Parkinson disease. My project in the lab is to study a non-human primate model of Parkinson disease, and the effects of a new drug, Carboxyfullerene (C3), on neurotransmitter levels and dopaminergic cells in different regions of the brain.

Richard D. Vierstra receives NIH grant

| Read Story

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.

Dr. Himadri Pakrasi receives U.S. Department of Energy grant

| Read Story

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.
