A video in Julie Greenwood’s lab catches cancer cells in the act of invading the brain. They are glioblastoma cells, agents of the same disease that killed Senator Ted Kennedy. “Glioblastoma cells are very effective at invading the neighboring tissue of the brain,” says Greenwood. “In many cases, these cells sprint.” Although surgery is often […]

In her first year in college (Pacific Lutheran in Tacoma), music almost won out over mathematics for Holly Swisher’s attention. During her high school years in Salem, she had played piano and bassoon in a youth symphony, sang in a choir and even played drums in the marching band. But her love of math wouldn’t […]

If you’re unlucky enough to get Lou Gehrig’s disease (aka, amyotrophic lateral sclerosis or ALS), treatment options are few. One drug, Riluzole, has been shown to marginally increase survival. Other drugs can be used to manage ALS symptoms, but there is no cure. For more than a decade, Joe Beckman has been studying the chemistry […]

For Courtney Jackson, everything began when she saw a shark swim across a television screen. She was in second grade, and the Discovery Channel’s Shark Week took her underwater and face-to-face with fearsome predators. At the end of it, she came to one conclusion: She wanted to be the scientist swimming with the sharks. A […]

A half-ounce flying mammal, a tiny marsupial that glides from tree limb to tree limb, and a hairless, burrowing rodent with supersize front teeth all share a trait that makes them intriguing to researcher Viviana Perez: exceptional longevity. The little brown bat (Myotis lucifungus), common across North America, has been known to live more than […]

When Annika Swanson arrived as a freshman at Oregon State in 2010, she already had a life purpose: join the ranks of research faculty studying the causes and effects of environmental pollution. “I’ve always had a deep interest in the environment and in environmental toxins and pollution. This began when I was younger and my […]

Some of today’s flat-panel TV and computer screens are nearly as big as a living room wall. They bring us unimaginably sharp detail, from the spots on butterfly wings to the grimace on a linebacker’s face. Whether hooked up to your cable feed, DVD player or wi-fi, this technology is becoming integral to daily life. However, our love of flashy high-res has a dark side.

The term “God particle” tends to rankle physicists. The flippant reference to the recently discovered particle believed to be the Higgs boson was coined by Leon Lederman, the former director of the Department of Energy’s Fermilab and Nobel Prize winning physicist. But, says Ken Krane, nuclear scientist and emeritus professor of physics at Oregon State […]

It’s one of life’s little ironies. The proteins in our bodies fight infection, carry messages, ferry oxygen and build tissue. But then, like double agents in a spy novel, they can betray us. They overreact to a virus and attack our own organs. They promote cancer, help clog arteries or set up roadblocks in the […]

One sunny spring afternoon, friends sat together in the backyard of a Corvallis home sipping wine, bemoaning the recent hike in gas prices to $3.50 per gallon. Among them were a former product-development specialist for Hewlett-Packard and an Oregon State University chemist. Perhaps inspired by the bioethanol in their glasses, what might happen, they wondered, […]

Ancient Blood Brothers Like the “sloth moth,” which lives only in the fur of the ambling two-toed and three-toed mammals, the “bat fly” exists only in the fur of the winged, cave-dwelling mammals. Now scientists know that the flea-like, blood-sucking fly has been hanging around with bats for at least 20 million years. That’s because […]

There’s nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses has come in the form of an advanced method for analyzing data from X-ray crystallography experiments. Reported in this week’s issue of […]

Fungi are master recyclers, turning waste into nutrients and providing humankind with everything from penicillin to pale ale. Although fungi are members of one of the world’s most diverse kingdoms, we know relatively little about them. That is about to change. A new study headed by Joseph Spatafora, an Oregon State University professor of botany […]

When Sam Bartlett, an Oregon State University senior in chemistry, put on his lab coat, goggles and latex gloves in the summer of 2010, he didn’t expect to wind up helping organic chemists around the world. With guidance from Chris Beaudry, assistant professor of chemistry, he developed the most efficient and productive method yet reported […]

Walk into an upper-level college physics classroom almost anywhere in the country, and you’ll see students sitting down, listening to the professor and taking notes. Despite years of education research showing that students learn better by being active, the common curriculum for juniors and seniors in physics still emphasizes passivity. In recent years, a revolution […]

Microbes are masters of adaptation. In some of Earth’s most extreme environments — Antarc- tica’s frigid ice fields, Yellowstone’s sulfuric hot springs, Crater Lake’s lightless depths, the oceans’ deep-sea basalts — Stephen Giovannoni has discovered thriving communities of bacteria. As the holder of the Emile F. Pernot Distinguished Professorship in Microbiology, he has discovered some […]

Unnoticed by most beach–goers, a showdown is under way in Oregon’s coastal dunes, and the winner could pack increased risks for coastal property, especially during winter storms. OSU scientists have documented a slow but steady takeover by American beach grass (Ammophila breviligulata), an invasive species from the East Coast and Great Lakes. They have found […]

The next time you sip a glass of spring water, consider this: Before it got to your lips, that water was soaking through soil, creeping along basalt crevices or flowing through porous volcanic rock. It nurtured microbes, carried dissolved minerals and may have spread the byproducts of human activities. Its pivotal role in the environment […]
