Vanderbilt researcher finds evidence for ant caste systems driven by chemo-sensing responses
Mar. 13, 2023—By Andy Flick, Evolutionary Studies scientific coordinator Stephen Ferguson, first-author of a new paper with his postdoctoral advisor, Laurence Zwiebel, Cornelius Vanderbilt Chair in Biological Sciences, and two undergraduates associated with the lab, Isaac Bakis (alumnus) and Nicholas Edwards, confirmed the existence of a specialized soldier caste within an ant species in a paper titled,...
Researchers hope insights into low-light vision of Antarctic icefish can promote better understanding of human health
Feb. 27, 2023—By Tatum Lyles Flick, Evolutionary Studies communications volunteer consultant Though many researchers have considered how fish survive in extreme cold, using everything from antifreeze glycoproteins that protect cells to not producing hemoglobin, few have taken a molecular approach to evaluate how they are able to see in such conditions. In “Adaptation of Antarctic Icefish Vision...
Vanderbilt-led Group Discovers Divergent Function in Convergent Evolution of Form
Feb. 22, 2023—By: Andy Flick, Evolutionary Studies scientific coordinator The classic idiom form fits function does not always mean that everything of the same form has the same function. That’s what a group of paleontologists have discovered with the help of fluid physics and preserved fossils. Simon Darroch, assistant professor of Earth and Environmental Sciences, led a...
Vanderbilt Researcher Identifies Modes of Natural Selection in Understudied Human Populations
Feb. 16, 2023—By Andy Flick, Evolutionary Studies scientific coordinator (Spanish/español) Amanda Lea, assistant professor of biology, along with a global team of experts, have discovered new pathways of natural selection in humans. The group, led by Tsimane Health and Life History Project co-Director Michael Gurven of the University of California, Santa Barbara, studied two populations of Bolivians...
Ogden lab discovers new interactions between viruses during dual infections
Dec. 7, 2022—By: Andy Flick, Evolutionary Studies scientific coordinator Kristen Ogden, an assistant professor in the Pediatrics and Pathology, Microbiology and Immunology departments, studies what happens when two viruses attack the same cell – also known as coinfection. In a recent study led by an alumnus of her lab, Tim Thoner, the team discovered that the time...
Vanderbilt Graduate Student Parses Out Differences in Virulence across the Aspergillus Genus
Dec. 5, 2022—By Andy Flick, Evolutionary Studies scientific coordinator Annie Hatmaker, along with an excellent team of researchers including her advisor, Antonis Rokas, recently published a study identifying differences in virulence among Aspergillus species. Aspergillus is a common human-pathogenic genus of fungi that includes A. flavus which can cause aspergillosis and fungal keratitis infections, a nasty eye...
