  • The image depicts a layered conceptual illustration of selfish mitochondrial genomes undergoing selection at multiple levels. The bottom layer features scientists working at computers and conducting lab experiments, symbolizing empirical research. The middle layer shows a tiered structure with enlarged mitochondria, emphasizing the levels of selection within organisms. Surrounding elements include graphs, lab equipment, and symbolic representations of data analysis, highlighting the integration of experimental and mathematical modeling without any textual elements. The overall scene captures the complexity and interconnectedness of mitochondrial genome selection in a visually engaging and educational format.

    Mitochondrial DNA Evolution: New Study Reveals How Selfish mtDNA Evolve and Thrive

    By Andy Flick, Evolutionary Studies scientific coordinator Bryan Gitschlag Vanderbilt University researchers, led by alumnus Bryan Gitschlag, have uncovered groundbreaking insights into the evolution of mitochondrial DNA (mtDNA). In their paper in Nature Communications titled “Multiple distinct evolutionary mechanisms govern the dynamics of selfish mitochondrial genomes in Caenorhabditis elegans,”… Read More

    Vanderbilt Researchers Find Warming Quickens Aging-Related Mortality in Mosquitoes

    By Andy Flick, Evolutionary Studies scientific coordinator Barr (left) and Hillyer in the lab. Submitted photo 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… Read More

  • Two side-by-side images. On the left, a petri dish containing a fluffy white fungal colony with several circular growth patterns, representing a laboratory culture of the fungus Aspergillus. On the right, a close-up microscopic image showing the detailed structure of an Aspergillus spore head, with a dense cluster of greenish spores radiating from a central point, displaying the intricate texture and morphology of the fungal spores.

    Researchers Discover Wide Variation in Virulence of Non-Pathogenic Fungi

    By Andy Flick, Evolutionary Studies scientific coordinator A new study led by research assistant professor David Rinker sheds light on how fungal pathogenicity might evolve. The article, “Strain heterogeneity in a non-pathogenic Aspergillus fungus highlights factors associated with virulence,” was published in the journal Communications Biology in September 2024.

    Researchers Discover the Evolution of Seasonal Anticipation in Cyanobacteria

    By Andy Flick, Evolutionary Studies scientific coordinator Being able to correlate changes in day length with seasonal weather patterns is crucial for many organisms to adapt to their environments. Trees shed their leaves, arctic foxes grow thicker coats, and bears prepare for hibernation. But what about smaller, short-lived organisms? New… Read More

  • A historical museum exhibit featuring a large fossilized skeleton of a prehistoric animal mounted vertically on a wooden support, with its ribcage and skull prominently displayed. In the foreground, there is a large tusk and skull of a mastodon. Multiple glass display cases filled with various fossils and geological specimens are arranged around the room. The room has tall windows with arched tops, a wooden ceiling with exposed beams, and framed pictures hanging on the walls.

    Rediscovering the Lost Plesiosaur (Cast): Restoring Vanderbilt’s Natural History Museum

    By: Andy Flick, Evolutionary Studies scientific coordinator 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… Read More
