In the ghoulish world of infectious disease agents, prions might well be the zombies. Unlike bacteria and viruses, prions have no DNA, yet still manage to replicate. Nearly indestructible themselves, the tiny agents slowly ravage the brains of their victims in an infection that is always fatal.
Prions were the culprit behind the mad cow disease outbreak in the late 1990s and early 2000s. And today, they’re driving the epidemic of chronic wasting disease (CWD) spreading rapidly through deer and elk across North America.
For nearly thirty years, Don Knowles ’88 PhD has bravely investigated these strange and elusive infectious particles. When asked if he … » More …
Humans generally think of themselves as highly evolved creatures, but when it comes to stress, our fear response is as primitive as the tiny beasts that fled predators 500 million years ago. Though lifesaving, this fight-or-flight system is also triggered by modern concerns such as political Facebook posts or being stuck in traffic. Over time, psychological stress can build into an internal time bomb.
While some suggest humans have outgrown their stress system, studies show there are ways to teach that old brain new tricks, helping to calm the angst that comes with contemporary living.
Imagine sitting on a park bench waiting for a friend. You’re checking messages on your phone when a noise catches your attention. You look up and suddenly realize it’s a beautiful autumn day. The sun is warm on your skin and a gentle breeze tempers the heat.
From a nearby tree, birds call while a few golden leaves flutter, break loose, and slowly drift to the ground. On the grass, a parade of tiny black ants drags a bread crumb. Traffic passes in the distance. Quiet voices chat and laugh.
The scene is a simple example of mindfulness, and your brain loves it, especially during … » More …
The straggly plant is easy to dismiss. Narrow leaves and white, trumpet-like flowers, fade easily into Northwest fields and roadsides. But Nicotiana attenuata, commonly known as coyote tobacco, contains medicinal and ceremonial properties long revered by Native American cultures.
For thousands of years, coyote and other types of wild tobacco have provided what many consider a versatile healing remedy and meditative, spiritual channel to the Creator. Much of the botanical lore was muddled, however, with the arrival of Europeans and subsequent cultural upheaval.

“Life can multiply until all the phosphorus is gone, and then there is an inexorable halt which nothing can prevent. We may be able to substitute nuclear power for coal, plastics for wood, yeast for meat, and friendliness for isolation—but for phosphorus there is neither substitute nor replacement.”
The Greeks called phosphorus “the bearer of light,” a chalky white mineral that ignites spontaneously and gives pizazz to matchsticks and fireworks. Theories suggest it even arrived on Earth in a fiery meteorite crash billions of years ago.
The fifteenth element could also be called the bearer of life. Wound into DNA … » More …
High in the Cascade and Olympic Mountain snowfields, pristine rivulets trickle into brooks that descend through forest, farmland, and town. Streams merge into rivers and sweep through cities until finally breaking into Puget Sound and the marine waters of the Pacific.
There, in the southern arm of the Salish Sea, the waters mingle in a fertile estuary teeming with biodiversity.
“Looking out at the waters of Puget Sound, you see the sunset, the beautiful mountains, and people think, ‘Everything is good, we’ve got the orca.’ But we have invisible problems,” says Chrys Bertolotto, natural resource programs manager at the Washington State University Snohomish County … » More …

“There he is!” I look up as tattered orange wings flutter above the sunflowers. A lone male monarch butterfly hovers near the milkweed patch, gallantly hoping, says wildlife ecologist Rod Sayler, for the arrival of a female.
The scene took place early last August at the Washington State University Arboretum and Wildlife Center, where for the first time in 25 years, Sayler documented the iconic butterflies living and breeding on campus. Weeks earlier, to his astonishment, he’d found a handful of monarch caterpillars devouring the leaves of recently restored showy milkweed plants.
“The monarchs were a big surprise for me,” he says. “It’s the first … » More …
Veterinarians use an old remedy to eliminate the deadliest infectious disease known to humanity. Rabies.
It was the season for guavas. Their sweet musky fragrance drifted through the morning air and into the open window of seven-year-old Sharon Korir, beckoning her outside to play.
The year was 2003, the day after Christmas. As was customary, Sharon had traveled with her parents to their home village in rural Kenya for the holiday. When it came time to return to Nairobi, the doting grandparents asked Sharon to spend an extra day.
The rains had passed and that day arrived with welcome blue skies. Sharon and her friends … » More …
Graceful tropical fish circle around me as a sea turtle glides overhead. Slowly and steadily, hundreds of pink jellyfish swarm from behind and a curious striped creature moves in for a better look at what I assume is my virtual reality headset. In awe, I blindly reach out and it pulls away with alarm. The scene is so realistic I’m speechless.
Don McMahon is laughing. “You look pretty engaged right now,” says the director of the Washington State University Neurodiversity Lab located in the College of Education. “Fun is engaging and engaged students learn,” he’s been intoning, seemingly miles away in the background.
