A multi-disciplinary team at Oregon State University is using nanoparticles of iron oxide to help detect chemical and biological agents, proving again Neil Young’s truism that rust never sleeps. Existing methods for identifying chemicals are often time-consuming, and require expensive equipment and trained experts. So Pallavi Dhagat, a professor of computer science and electrical engineering, and Vincent Remcho, a professor of chemistry, assembled a cheap and efficient alternative: a tiny, all-in-one diagnostic laboratory in which the rust nanoparticles perform double duty. The iron oxide helps ferret out the chemical in question, then instantly relays the information, via magnetism and electronics, to a tiny computer, which in turn displays the results to the user. Funded by the U.S. Army Research Laboratory, in collaboration with the Oregon Nanoscience and Microtechnologies Institute, the magnetic “nanobeads” project began four years ago as a technology to locate bioterrorism toxins. But the system, which Remcho extols for its “sensitivity and specificity,” can also be used in any number of civilian applications, including medical diagnostics, environmental monitoring, and food and water safety. “It’s an amazingly flexible detection platform,” says Remcho, whose team is currently “miniaturizing ancillary components.” No rest for the rusty.

Mike Morrow and Mike Delos-Reyes first came up with the idea of an ocean power device 23 years ago, when they were students at Oregon State University. They realized a long-held vision last summer, when their startup, M3 Wave, successfully launched the first ocean power device that works underwater.

There are more than 160 farmers markets in Oregon, contributing an estimated $50 million in sales, according to the Oregon Farmers Markets Association. We checked in on the Forest Grove market, which for several years has brought local produce and food vendors to Main Street in the center of town.

Spring rains are the bane of an Oregon cherry farmer’s existence. Even a few sprinkles can crack the fruit so badly it’s not worth picking. Science to the rescue: Researchers at Oregon State University have developed a spray-on film that cuts rain-related cracking in half, potentially saving a season’s crop. The coating, patented as SureSeal, is made from natural chemicals similar to those found in the skins of cherries: cellulose, palm oil-based wax and calcium.

One hundred years ago, the Willamette River might easily have been mistaken for a sewer. Unchecked industrial activity and decades of pollution made it unrecognizable compared to the clean river that now flows north for 187 miles from Eugene through the center of Portland.
