A man with short dark hair, a beard, and glasses sits at a lab workstation. He wears a black hoodie and looks toward the camera with a slight smile. Behind him are two computer screens—one showing a terminal with lines of code and the other displaying a flowchart with scientific diagrams. Shelves above the desk hold plastic lab containers labeled “200 uL Filter” and “1000 uL Filter.”

A Conservative Defense: Downstream NFLs Resist Evolutionary Blitzes

May. 9, 2025—By Andy Flick, Evolutionary Studies scientific coordinator In football, defense keeps the opposing team in check. A similar strategy is at play inside our cells. Negative feedback loops (NFLs) help regulate how cells respond to signals, for example, dialing down activity when things get too intense. A new study from Vanderbilt University reveals that these...

Vanderbilt Researchers Find Warming Quickens Aging-Related Mortality in Mosquitoes

Sep. 19, 2024—By Andy Flick, Evolutionary Studies scientific coordinator Mosquitoes tread a thinning line in warming climates, where aging accelerates and infections intensify. New research shows that warming and aging act as a one-two punch, lowering mosquito lifespans and fanning the flames of bacterial infections. These findings highlight how climate change could alter the risks of disease...

A young man wearing glasses is seated at a desk, working on a computer. He is typing on a keyboard and looking at the code displayed on the monitor. The desk has shelves with various items, including a framed certificate, a potted plant, and some personal belongings. Another laptop is open on the desk, displaying a different screen.

Analyzing Evolutionary Trade-Offs in Immune Systems: Computational Biology with Reese Martin

Jul. 22, 2024—By Nick McCoy, Evolutionary Studies undergraduate communications assistant Reese Martin has always been drawn to biology and exploring the behaviors of different organisms. During his childhood, he dug in anthills, and now he observes the life history traits of flower beetles and other taxa. Martin’s new first-author paper, “Pleiotropy Alleviates the Fitness Costs Associated With...

Vanderbilt Researchers Flip the Script on Yeast Ecological Diversity

Apr. 25, 2024—By: Andy Flick, Evolutionary Studies scientific coordinator A mere decade or two ago, decoding the genome of every organism in a major branch of the tree of life and deciphering their diets was a pipedream. In a groundbreaking study, a team of researchers from Vanderbilt University, the University of Wisconsin-Madison, and other institutions worldwide have...

Beckman Scholar Charu Balamurugan Unveils Evolutionary Insights into Penicillium Secondary Metabolites

Mar. 26, 2024—By: Andy Flick, Evolutionary Studies Scientific Coordinator Beckman Scholar Charu Balamurugan, an undergraduate researcher in the Rokas lab at Vanderbilt University, has shed light on the intricate evolutionary patterns governing secondary metabolite biosynthesis in fungi. Working with former Ph.D. student Jacob Steenwyk, lab PI Antonis Rokas, and collaborator and Global Scholars Program participant Gustavo Goldman,...

Insect Immune Insights: Researchers Unveil Immune System Dynamics

Mar. 12, 2024—By Andy Flick, Evolutionary Studies scientific coordinator Justin Critchlow, a recent Ph.D. student in Ann Tate’s lab, just published a paper with the labmates Arun Prakash (postdoctoral researcher), Katherine Zhong (former undergraduate), and Tate, uncovering the intricacies of beetle immune dynamics. The paper was just published in PLoS Pathogens, “Mapping the functional form of the...

Breaking the Mold: Kyle David’s Research Challenges Ecological Norms in Yeast Communities

Feb. 27, 2024—By: Andy Flick, Evolutionary Studies scientific coordinator Kyle David, an NSF postdoctoral fellow in the Rokas lab, and co-authors published a new paper, “Saccharomycotina yeasts defy longstanding macroecological patterns” in the high-impact journal PNAS. This paper, which looks at the ecology of 186 species of yeast, provides evidence that not all life-forms follow the rules....

Vanderbilt University biologists discover that rising temperature accelerates aging in mosquitoes, weakening their immune system

Jan. 25, 2024—By Sarah Ward, Evolutionary Studies graduate communications assistant Climate change may weaken mosquitoes by speeding up aging and slowing down their immune system. A study published January 10, 2024 in PLOS Pathogens by Vanderbilt biology graduate student Lindsay Martin and Centennial Professor of Biological Sciences Julián Hillyer found that mosquitoes age more quickly when temperatures...

Vanderbilt Postdoctoral Researcher Reveals Genomic Secrets of Ocean Sponges

Dec. 4, 2023—By: Sarah Ward Evolutionary Studies graduate communications assistant Picture a thriving marine environment. Perhaps you envision a community as colorful and lively as “Finding Nemo,” where massive schools of fish are flanked by sharks and sea turtles. What about sponges? While perhaps less popular than their flamboyant counterparts, these organisms are the foundation of life...
