Vanderbilt Anthropologist Explores How Different Childcare Models Affect Child Health in Working Families
Sep. 12, 2024—By Andy Flick, Evolutionary Studies scientific coordinator A new study co-authored by Monica Keith, Assistant Professor of Anthropology, provides insights into how different childcare models affect child health outcomes in working families. The research, focused on subsistence-based, semi-nomadic Shodagor communities in Bangladesh, highlights the crucial role of maternal care and effective substitutes in maintaining child...
Researchers Discover Wide Variation in Virulence of Non-Pathogenic Fungi
Sep. 11, 2024—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. According to Rinker, “different isolates or...
Graduate Student Sheds Light on Ancient Worms as Early Ecosystem Engineers
Sep. 10, 2024—By Andy Flick, Evolutionary Studies scientific coordinator Graduate student Kat Turk from Vanderbilt University’s Department of Earth and Environmental Sciences, along with an international team of collaborators, has uncovered new evidence that ancient priapulid worms, through their burrowing behavior, may have been some of the earliest ecosystem engineers. The study, “Priapulid neoichnology, ecosystem engineering, and...
Researchers Discover the Evolution of Seasonal Anticipation in Cyanobacteria
Sep. 6, 2024—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 research led by BBSRC Discovery...
Rediscovering the Lost Plesiosaur (Cast): Restoring Vanderbilt’s Natural History Museum
Aug. 27, 2024—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 years in a dim, cluttered...
VU Graduate Student Uses Satellites to Provide Critical ALAN Data for Public Policy
Aug. 9, 2024—By: Alexandria Leeper, Evolutionary Studies Graduate Communications Assistant Imagine you are trying to stargaze. You live in a suburban area where there are little streetlamps, and the darkness of the night envelops most of the sky, making the stars visible. However, you are adjacent to a major city. When you turn your gaze towards that...
