Space farming

Surviving the challenges of deep space exploration could rely as much on botany as astrophysics.

NASA sees plants not only as potential food sources aboard future spacecraft but as natural oxygen producers. The space agency is preparing for its first in-depth study of how growth and development of plants is affected by gravity, or more specifically the lack of it.

“The overall significance is what it could mean for space exploration,” says Norman G. Lewis, a Regents professor at Washington State University’s Institute of Biological Chemistry and principal investigator for the NASA-funded study. “Whether it’s colonizing planets, establishing a station, … » More …

On Closer Inspection—The curiouser and curiouser world of the small

In some ways, with so much science now involving tools that detect things outside the five senses, examining the world with a microscope seems quaint. But a corps of WSU researchers—let’s call them microscopists—are wrangling photons, electrons, glowing proteins, exotic stains, and remarkably powerful devices in their pursuit of the small.

A blighted Northwest icon

Last March, Gary Chastagner was driving around southwest Oregon scouting test plots for a study of madrone, the gnarly, reddish-brown tree found up and down the West Coast. A variety of diseases had been hitting the trees in recent years, and Chastagner, a plant pathologist in WSU’s Puyallup Research and Extension Center, was undertaking a study to see if some varieties might be more disease resistant than others.

Driving between Roseburg and Medford, he started seeing entire slopes of trees that looked decidedly disease prone.

“It just looked like someone went through with a blowtorch,” Chastagner recalls.

Video: Build a Bouquet of Local Flowers

Diane Szukovathy from Jello Mold Farm in Washington state’s Skagit Valley puts together a bouquet of locally-grown flowers and offers tips to gardeners on building their own bouquet of blooms. Diane and her husband Dennis Westphall grow cut flowers. They have teamed up with Washington State University researchers Bev Gerdeman and Lynell Tanigoshi to build a community of local, seasonal flower growers in the Pacific Northwest. The growers sell at markets, directly to farmers, florists, grocery stores, and local businesses. Read more in “Business is Blooming.”

A New Land

John Bishop was late getting to Mount St. Helens.

He was only 16 years old when it blew in 1980, and it would be another decade before he began crawling around the mountain as part of his doctoral studies.

“I was worried I missed all the action—‘Ten years, it’s all been studied,’” he recalls.

It turns out the dust, pumice, and other ejecta were only beginning to settle, and the mountain would continue to rumble, spit, and recover. In 1994, he found himself running from a mudflow, then watched as it moved fridge-sized boulders and shook the earth beneath his feet. Arriving at WSU Vancouver … » More …

Borrowing nature's designs

In Michael Knoblauch’s lab, the gap between fundamental research and practical applications is a narrow one.

Knoblauch studies the inner workings of phloem (FLOAM), the channels that transport water and nutrients throughout a plant. Research doesn’t get much more basic than that—yet one of his recent discoveries is leading him straight to the patent office.

He’s found that structures in the phloem of some plants have great potential as high-tech, microscopic valves, sensors, and motors.

Knoblauch named the structures “forisomes,” which means “gate-bodies.” He found that they keep the phloem from leaking after it’s been injured.

Phloem is comprised of parallel tubes, or sieve elements, … » More …
