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 …

Creatures from the Dark Lagoons

Cynthia Haseltine wants everyone to know that the microbes she works with are not bacteria.

They look like bacteria; each Sulfolobus is a single cell that has one circular chromosome and lacks a nucleus. But in their genes and the way they read and repair their DNA, these organisms bear a closer resemblance to us than to bacteria—and those similarities make Sulfolobus an excellent model system for learning about how our cells handle DNA, and how the process sometimes goes wrong.

Haseltine’s microbes belong to the group of organisms known as Archaea (ar-KAY-uh). Most Archaea are extremophiles, living in hot, saline, acidic, or other extreme … » More …

Time will tell

Climate change is nothing new to our planet. But this time it's different. The carbon dioxide we are putting into the air through industry, vehicle emissions, and deforestation is changing the way our soil works. That in turn affects plant, animal, and eventually human life. Through their research Washington State University scientists are challenging the conventional view that more plants and forests will solve our CO2 problems. » More ...

Picture this

Doerte Blume is good at explaining difficult concepts. She draws as she talks, putting into pictures what she knows about the tiniest fragments of matter. Her desk is swimming in paper, with notes and graphs and sketches of atoms lapping at the sides of her computer and spilling against a jetty of books. As a theoretical physicist, she relies heavily on high-powered math; but for her, before the math come the images.

Working solely from equations “doesn’t get me very far,” she says. “I also have to have the physical picture of, what would I expect? What do the particles do? I always try to … » More …

Bring on the boron

Lai-Sheng Wang has an impish smile, an infectious laugh, and a high-powered research program that studies matter a few atoms at a time.

He uses massive machines to create tiny clusters of atoms. Wang’s clusters aren’t mere lumps. As the magnetic models stuck to his file cabinets show, they are as geometrically elegant as a snowflake.

Wang came to the public’s attention three years ago when his team at the Pacific Northwest National Laboratory in Richland became the first to make golden buckyball, a hollow cage of 16 to 18 gold atoms. He has also worked on clusters of aluminum, another element with a long … » More …

Mixing it up

Not since white settlers surged west, overwhelming the native population, has Washington been at all diverse in its population, at least if one defines “diverse” by ethnicity rather than European country of origin. By 1890, whites represented 97 percent of Washington’s recorded populace, and that number remained static for decades. Now that mix has started to change. Just recently, the white (not Hispanic) portion of Washington’s population dropped below 80 percent, for the first time since the mid-19th century.

Annabel Kirschner, a professor in the Department of Community and Rural Sociology and an extension specialist, recently released “Increasing Diversity in Washington State 2000–2008,” the … » More …
