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.
All the world’s a stage for CAS students, whether they’re on the screen, in the classroom, in the lab or beyond. Hear from Dean Chris Poulsen about how humanities programs like theatre arts and cinema studies build valuable skills—and how storytelling fosters an understanding of what it means to be human. And if you’re in the Eugene area, buy your tickets for the University Theatre production of POTUS, which runs Feb. 7-23.
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.
PHYSICS - Professor Tien-Tien Yu is one of nearly 400 scientists and engineers awarded the Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the US government on outstanding scientists and engineers early in their careers.
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.
CHEMISTRY AND BIOCHEMISTRY- Antibiotic resistance could pose a problem for humans in the future. Farmers use antibiotics in livestock to combat pathogens, which could result in human consumers being immune to the drug that staves off bacterial infections. CAS students like biochemistry undergrad Favour Foday are working on ways to address big problems like human antibacterial resistance or the looming energy crisis.
PHYSICS - The National Science Foundation has awarded a one-year, $1 million grant to a team led by University of Oregon researchers exploring practical applications for emerging quantum technologies and working to move discoveries beyond the lab. “Oregon has a small group of proficient researchers leading the way globally in quantum technology," said Brian Smith, a professor of physics and director of the Oregon Center for Optical, Molecular and Quantum Science.
PSYCHOLOGY - Brice Kuhl is the first faculty member awarded the Dr. Michael Posner Psychology Professorship in Cognition and Neuroscience. This brand-new professorship, awarded in honor of the Department of Psychology’s groundbreaking researcher Michael Posner, will help support Kuhl’s teaching, research and professional development.
The world looks different in the laboratories buried 17 feet beneath campus, where you can pick up an object 1,000 times smaller than the width of a human hair and peer at its individual atoms. In UO’s underground materials characterization labs, researchers are pushing the boundaries of what can be observed through a microscope. Read more in the December sci-fi issue of CAS Connection.
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.
PHYSICS - Could life exist elsewhere in the Milky Way galaxy? A group of College of Arts and Sciences undergraduate planet hunters are helping NASA discover unknown worlds beyond our solar system. Read more in the December sci-fi issue of CAS Connection.
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.
EARTH SCIENCES - Graduate student Annika Dechert at the University of Oregon College of Arts and Sciences and a team of researchers are working on studying the eruption history of South Sister volcano in the Oregon Cascades. The results of the study will inform the way the USGS Cascades Volcano Observatory draws up hazards maps for Central Oregon and help shape the way scientists think about other similar volcanoes. The research team published their latest findings in August in the journal Geochemistry, Geophysics, Geosystems.
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.
