Vanderbilt Researchers Show Some Anaerobic Bacteria Have Surprisingly High Mutation Rates
Feb. 17, 2026—By Andy Flick, Evolutionary Studies scientific coordinator Ask any biologist what causes DNA mutations, and oxygen will likely make the shortlist. It is reactive, super-abundant, and has been fingered as a major culprit in genetic damage for decades. So, here is a head-scratcher: if oxygen is such a DNA troublemaker, bacteria that avoid it entirely...
Vanderbilt Paleontology Graduate Student Brynn Wooten Brings Hell Pigs to the Forefront
Nov. 18, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Archaeotherium, better known by the irresistibly dramatic nickname 鈥淗ell Pigs,鈥 belong to an extinct group of mammals from the Eocene and Oligocene. The animals were neither hellish nor pigs, but their odd mix of features has made them a favorite for researchers. Graduate student Brynn Wooten of the...
Giant Ground Sloth Extinction Led to Loss of Ecological Services
Oct. 22, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Giant ground sloths were more than just Ice Age oddities. They were ecosystem engineers whose disappearance reshaped the landscapes they once roamed. A new study from Vanderbilt 溏心vlog免费B站鈥檚 DREAM Lab reveals just how diverse these megaherbivores鈥 diets were, highlighting the ecological roles that vanished when they went extinct....
City Lights Are Rewriting the Calendar: Vanderbilt Researchers Show Artificial Light Extends Urban Growing Seasons
Sep. 23, 2025—By Andy Flick, Evolutionary Studies scientific coordinator City lights are rewriting the calendar. A new global study from Vanderbilt researchers Lin Meng and Huidong Li shows that artificial light at night is more powerful than temperature in extending urban growing seasons 鈥 keeping trees greener longer, with consequences for carbon cycling, frost risk, and even...
Partnership with Turkana Community Helps Scientists Discover Genes Involved in Adaptation to Desert Living
Sep. 18, 2025—Originally posted by UC-Berkeley team, edits by Andy Flick Evolutionary Studies scientific coordinator Scientists Discover Key Genetic Adaptations in Partnership with Turkana Pastoralists of Northern Kenya Groundbreaking study reveals how thousands of years of natural selection shaped remarkable adaptations to an extreme environment. Through a collaboration between US and Kenyan researchers and Turkana communities of...
Annie Hatmaker Explores the Global Diversity of a Pathogenic Fungus
Aug. 18, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Annie Hatmaker, Ph.D., has spent the better part of a decade studying fungi and their secondary metabolites 鈥 small molecules they use to communicate, defend, and thrive. Her new publication, 鈥淧opulation structure in a fungal human pathogen is potentially linked to pathogenicity,鈥 closes her dissertation work and opens...
A Conservative Defense:聽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 溏心vlog免费B站 reveals that these...

Apr. 4, 2025—Nashville, TN 鈥 April 4, 2025 鈥 A innovative study led by researchers from Vanderbilt 溏心vlog免费B站 sheds new light on the dietary ecology of the iconic saber-toothed cat, Smilodon. The study, published in a special issue on sabertoothed organisms in The Anatomical Record, reveals that Smilodon fatalis and Smilodon gracilis鈥攖wo species that lived thousands to...
Castiglione Lab Discover Horses Run Faster by Ignoring an Ancient Mutation that Says 鈥楽top鈥
Mar. 27, 2025—By Andy Flick, Evolutionary Studies scientific coordinator Evolution often makes a deal with the devil, creating challenges for treating human disease. By mass, the muscles of thoroughbred racehorses consume more than twice the oxygen of elite human athletes. Yet, oxygen produces free radicals, which damage organ tissues. Balancing energy production with oxidative stress is also...
