Danial Asgari, a postdoctoral researcher in the Tate Lab, and Ann Tate, associate professor of Biological Sciences, recently published a study in Molecular Biology and Evolution titled “How the Structure of Signaling Regulation Evolves: Insights from an Evolutionary Model.” Their findings show that negative feedback loops (or NFLs) acting closer to a cell’s final decisions, such as turning genes on or off, are especially resistant to evolutionary change.

In a groundbreaking study led by Sarah Worthan, Ph.D., a postdoctoral researcher in the Behringer Lab at Vanderbilt University, scientists have successfully evolved microbial cultures that possess the ability to sense pH changes, enabling rapid responses to environmental fluctuations. Read More

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 spread by mosquitoes. Read More

New research led by recent Vanderbilt Ph.D. alumna Maria Luísa Jabbur from the Johnson Lab and BBSRC Discovery Fellow at the John Innes Centre, in the UK has uncovered that even cyanobacteria—tiny organisms with a generation time of just five to six hours—can sense and respond to changes in light availability, or photoperiod, to gear up for winter.

Embarking on a new research project often brings unexpected discoveries—some intriguing, some novel, but rarely a find of a lifetime. Such a remarkable discovery occurred when university archivist and associate director Kathy Smith stumbled upon a pile of plaster, hidden away for 60 years in a dim, cluttered closet of the Branscomb Quad basement. This plaster turned out to be the long-lost Crampton’s Plesiosaur Cast from the 1870s, missing for nearly six decades. Read More

Research projects investigating the history of evolution at Vanderbilt University led to the rediscovery of a long-lost Crampton’s Plesiosaur Cast from the 1870s. Read More

The Creanza Lab, along with alumnus Matt Wilkins, BA’06, created a birdsong identification lesson plan for middle and high school students. The game show lets participants identify which birds they can hear in various pop culture media, such as movies, music, or video games. Read More

A mere decade ago, decoding the genome of every organism in a major branch of the tree of life and deciphering their diets was a pipe dream. In a groundbreaking study, a team of researchers from Vanderbilt University, the University of Wisconsin-Madison and other institutions worldwide have done just that for the first time ever. Led by Abigail LaBella, a postdoctoral researcher in the Rokas Lab, an international research team used the genomes and diets of nearly all known species from an ancient lineage of yeasts to understand the evolution of generalists and specialists.  Read More

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. Balamurugan delved deep into the genomes of Penicillium species, uncovering fascinating insights into the conservation and evolution of biosynthetic gene clusters and associated resistance genes.
