    Gall Wasps and Hyperparasites

    Gall on Cola-nut by Roger Griffith, 2008, public domain

    You're likely familiar with parasites: organisms that live in or on another at the expense of the host. You might not be aware, however, that parasites can themselves get parasites, known as hyperparasites. Even hyperparasites can get parasites, with as many as four layers of parasitism! As with many things, it's turtles (or, in this case, parasites) all the way down.

    The arboretum is home to a number of parasites and hyperparasites. One of the most common is the gall wasp, which is really a family of wasps that lay eggs in plant tissues. Read more about gall wasps and hyperparasites in this article written by Cole Student Naturalist Nico Bolling '27.

    Jeong Hyun '01 and Ben Pham '23 publish in Cell about Crohn's disease research. “Our lab at Stanford University just published an article in Cell regarding the metabolic activity of adipose tissue in Crohn’s disease intestinal fibrosis. One of the main authors was Ben Pham ’23, who I hired into my lab through Coach Tom Journell’s 4 for 40 initiative, which aims to connect current Carleton football students to alumni working in their field of interest. This is a great example of how Carleton connections can lead to meaningful impact across the generations to make a difference!” - Jeong Hyun
     
    Will Zhong ’28Ellie Hopkins ’27Yiping Zou ’27, and James Zhang ’26 were awarded third place for their submission to the HeatMap Hackathon. Their submission focused on analyzing geographic and demographic disparities in burn care access, using data-driven methods to identify underserved populations and recommend targeted strategies for improving equity in care delivery. They were the sole undergraduate-only team to be selected as finalists. Amanda Luby, assistant professor of statistics, and Emily Kurtz, visiting assistant professor of statistics, served as advisers.
     
    Benedict Le '28, a biology major, prepared a compelling art exhibition in the Weitz. Titled "Conservation Conversations: An Exploration of Zoo Display," the exhibition featured photography that examined themes and questions Le encountered during his travels abroad.
