Electron microscopes light up the world of the small

For a place that takes pictures with what amounts to controlled bursts of lightning, the lab is quiet, almost hushed. Standing in the entrance to Oregon State University’s Electron Microscopy Facility (EMF), you might hear researchers’ soft voices as they discuss the best way to see pollen on a bee’s tongue or to look at […]

Electron microscope helps pinpoint a disease-causing virus

Rocky Baker, supervisor of the virology lab in the Oregon State University Veterinary Diagnostic Laboratory, identified this influenza virus in pet ferrets whose owner had come down with the flu. Ferrets are susceptible, he says, and the owner was concerned that his animals became sick after contact with a family member who had influenza symptoms. […]

Through the Needle

Disease reduces Douglas-fir growth, costs more than $200 million annually

On the surface of a Douglas-fir needle, the spore of a fungal pathogen, Phaeocryptopus gaeumannii, germinates and sends forth threads (hyphae). It matures into an organism that will grow inside the needle and reproduce. By interfering with the tree’s ability to exchange air and water, it shuts down photosynthesis. Thus starts a disease known as […]

Oysters on Acid

Ocean acidification dooms young oysters

The oceans are about 30 percent more acidic than they were a century ago, and scientists are beginning to understand the consequences for marine ecosystems. Oysters may provide an early warning of what’s to come. George Waldbusser, a biogeochemist in the College of Earth, Ocean, and Atmospheric Sciences, and Elizabeth Brunner, a master’s student, conducted […]

Function follows form in molecular structure

In Alex Chang’s lab in the School of Chemical, Biological and Environmental Engineering, researchers arrange atoms in precise patterns to create materials with novel electrical and heat-transfer properties. Chang and his colleagues use electron microscopy to visualize and analyze structures that are often only a few atoms thick. “The EM facility is very important for […]

Illuminating Plankton

Consuelo Carbonell-Moore has made it her life’s work to document the diversity of one of the ocean’s most abundant life forms: dinoflagellates, a type of plankton. These organisms are no mere bystanders in marine ecosystems. Some produce life-giving oxygen. Others influence the formation of coral reefs. In coastal waters, they can bloom as “red tides” […]
