Cool, Soothing, Lucrative Mint

If you drive through Central Washington’s mint-growing country in mid-summer, you’re likely to be overwhelmed by the scent of mint rising like an exhalation—at once delightful and inescapable—from the surrounding fields. In fact, your senses might deceive you into believing that not much has changed in the last 30 years or so. But during that time Rod Croteau, professor at the Institute for Biological Chemistry at Washington State University, has been doing research that has helped make Washington mint plants produce more and better peppermint.

Peppermint plants produce menthol, which is a terpene, as are all the other compounds Croteau researches. Terpenes are chemicals put … » More …

Ann Christenson's Time Piece

Bringing disparate images together into a unified whole seems to come naturally to ceramic artist Ann Christenson, professor of fine arts at Washington State University. It’s particularly evident in one of her most recent projects-a sundial.

Christenson was one of several artists invited by the University of California, Berkeley, to submit a design for the sundial, as part of the renovation of a courtyard within the Clark Kerr Campus at the university. The limitations imposed upon the design-that part of the area containing the sundial could be flat and that sundial parts be theft proof-led Christenson to choose an analemmatic sundial of tile and bronze … » More …

As you read this, thank your ion channels

When Mike Varnum, assistant professor, Veterinary and Comparative Anatomy, Pharmacology, and Physiology, visits the aquarium, he looks at the sea creatures a bit differently than the rest of us. What interests him most about a creature is not its bright color or odd shape, but whether it makes a toxin that blocks an ion channel. Oddly, many of the creatures do.

Many toxins, in fact, block specific ion channels, though Varnum uses different agents in his work. Ion channels are pores in the membranes of many different types of cells-highly selective, gated pores-that permit the passage of specific charged particles, or ions, into or out … » More …

A Vision Thing: Diagnostic tools and a vaccine for paratuberculosis

Bill Davis, professor of veterinary microbiology and pathology at Washington State University, exhibited true vision in the 1970s, when he recognized the potential for veterinary science of monoclonal antibody technology.

Antibodies are proteins produced by cells of the immune system. They help neutralize pathogens and produce immunity. Most pathogens stimulate their hosts to produce a population of diverse antibodies. Monoclonal antibodies, on the other hand, are populations of identical antibodies and are created in the laboratory. A given monoclonal antibody might be specific for an individual cell type, its state of activation, the strain of a pathogen, such as the 0157:H7 component of the infamous … » More …

Minding her B’s & T’s

In the fast paced world of immunological research, it’s not your p’s and q’s you have to mind, but your b’s and t’s. That’s B cells and T cells, two of the main players in the complex orchestra that makes up your immune system. B. Paige Lawrence, assistant professor in the College of Pharmacy, keeps track of both in her research into how the environmental contaminant dioxin affects immune system function but spends most of her time with T cells.

Dioxins are the byproducts of many industrial processes, including the incineration of municipal and medical wastes and of plastics. While they are destroyed by heat, … » More …
