Sibling scientists and their dog hunt for Oregon’s hidden truffle biodiversity

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.

Humanities Take Center Stage

All the world’s a stage for CAS students, whether they’re on the screen, in the classroom, in the lab or beyond.

And if you’re in the Eugene area, buy your tickets for the University Theatre production of POTUS, which runs Feb. 7-23.

Octopuses have some of the oldest known sex chromosomes

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.

Bad bacteria can trigger gut pain, new research shows how

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.

Atop the Oregon Cascades, UO team finds a huge buried aquifer

EARTH SCIENCES - Oregon’s Cascade Range mountains might not hold gold, but they store another precious resource in abundance: water. Scientists from the University of Oregon and their partners have mapped the amount of water stored beneath volcanic rocks at the crest of the central Oregon Cascades and found an aquifer many times larger than previously estimated — at least 81 cubic kilometers.
