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.

BIOLOGY - Women with a harmful mutation in the BRCA1 or BRCA2 genes have a 60 percent chance of developing breast cancer at some point in their lives, and a many-fold increased risk of developing ovarian cancer. UO College of Arts and Sciences biologists have uncovered how BRCA1 gene influences fertility. “This is a breakthrough discovery that enables potential therapeutic avenues for understanding how to correct or treat fertility issues in BRCA1 patients,” said Diana Libuda, an associate professor in the Institute of Molecular Biology at the UO.

BIOLOGY, ENVIRONMENTAL STUDIES - Ecologists from the University of Oregon have designed a soil health management system to strengthen the long-term vitality of the state’s hazelnut industry. Oregon produces 99 percent of the nation’s hazelnuts, but the escalation of global extreme heat, which brings dry soil and scalded plants, threatens the agricultural productivity of the region.

Three College of Arts and Sciences researchers have received the National Science Foundation’s most prestigious honor for early-career faculty members in the past year: Luca Mazzucato (biology, mathematics and physics), Brittany Erickson (computer science and earth sciences) and Julia Widom (chemistry). Known as the CAREER Awards, the organization recognizes and fosters rising stars by funding innovative research.

BIOLOGY - People are living longer, but that comes with age-related health issues, including Alzheimer’s disease, osteoarthritis and dementia. Biology Professor Patrick Phillips is spearheading a new research initiative focused on age-related diseases. The effort employs technology that will accelerate discovery and fuel new approaches to research, launched with a major gift from longtime UO donors Kenda and Kenneth Singer.
