BIOLOGY - Lauren Hallett, biology associate professor at the College of Arts and Sciences discusses her ongoing work to enhance the climate resiliency of Oregon’s hazelnut farms, which account for 99% of the country's hazelnut production. With the support of a $2 million federal award, Hallett and her lab have designed an agricultural practice using native cover crops and basalt dust amendments to set a new standard for sustainable hazelnut farming.

BIOLOGY - An expert on child and adolescent development and an expert on host-microbe interactions have each been recognized by the Medical Research Foundation of Oregon of the Oregon Health and Science University. Karen Guillemin, professor and Philip H. Knight Chair in biology in the College of Arts and Sciences, received the Discovery Award for her significant contributions to health-related research.

BIOLOGY - New in 2025, the Coastal Quarter program allows undergraduates from all majors to spend winter term living at the coast and taking classes in marine biology, environmental studies, anthropology and science communication. Out of the nine students who participated this year, five are majoring in either environmental sciences or environmental studies; four are marine biology majors; and one is a sports journalism major.

BIOLOGY - An AI-based imaging system that is a collaboration between researchers at the University of Oregon and Oregon State University, funded by the National Council for Air and Stream Improvement Inc., is working to monitor bee populations without harming the insects. The technology could solve a key paradox in bee conservation efforts. The collaboration includes CAS biologist Lauren Ponisio.

BIOLOGY - Franklin W. Stahl, a molecular biologist who helped create a methodology to confirm how DNA replicates that was so elegant, it has been remembered for more than five decades as “the most beautiful experiment in biology,” died on April 2 at his home in Eugene. He was a professor in the College of Arts and Sciences.

BIOLOGY - College of Arts and Sciences biology PhD student Heather Dawson and her sister Hillary Dawson and dog Rye are cataloging some of Oregon's truffles, which may be affected by warming temperatures and the increasing magnitude of wildfire season. The team's catalog contains more than 50 genera, or broad categories, of truffles since he began searching in 2020. The sisters’ latest data, published in a 2024 paper in the journal Ecology and Evolution.

BIOLOGY - University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on the evolutionary tree. That makes it one of the oldest known animal sex chromosomes. Doctoral students Gabby Coffing, Andrew Kern and their team described the findings Feb. 3 in the journal Current Biology.

BIOLOGY, PHYSICS - A new study published in the journal mBio shows how one kind of bacteria, Vibrio cholerae, triggers those painful contractions by activating the immune system. The research also finds a more general explanation for how the gut rids itself of unwanted intruders, which could also help scientists better understand chronic conditions like inflammatory bowel disease. The research was led by Julia Ngo, a now-graduated doctoral student in Karen Guillemin and Raghu Parthasarathy’s labs.

BIOLOGY - In 1924, the University of Oregon began teaching marine biology classes in a ramshackle collection of tents in a cove along the southern Oregon Coast. But what started as a couple of professors bringing some students on a summer camp has now become a permanent, year-round marine field station with a hundred years of coastal research and education.
