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.

Engineering the Future

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.

NSF picks the UO to pilot National Quantum Virtual Laboratory

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.

Tiny Invisible Universes

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.

A century beneath the waves

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.

Strange New Worlds

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.

Researchers unravel how a breast cancer gene affects fertility

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.
