Flushing the toilet stirred up a good idea in four young women from Walla Walla High School. They recognized that families use hundreds of gallons of water per day, a real problem in places faced with water shortages. To ease that, Karen Maldonado, Edlyn Carvajal, Sandra Escobedo de la Cruz, and Ruth Garcia developed a trapping system using an inexpensive charcoal filter to recycle wastewater back to the toilet tank.
The Walla Walla teens took their plan to the Alaska Airlines Imagine Tomorrow competition, an annual problem-solving challenge at Washington State University that encourages high school students to propose and present ideas … » More …
“I do not believe that any man can adequately appreciate the world of to-day unless he has some knowledge of … the history of the world of the past.” —Theodore Roosevelt, 1911

There’s the day the polar bear mangled the meteorological instruments. Or when a massive storm smashed two humidity sensors. Days of howling winds, extremely limited visibility, and weather so cold that power cords snapped like twigs.
A jar of foul-smelling clay sits on the cluttered workbench. “I’d better not open it,” says environmental engineer Richard Watts. He grabs a smaller jar filled with liquid the color of a dirty mud puddle. “These are soil and groundwater samples from an industrial waste site in North Carolina.”
The repugnant samples arrived in comparatively pristine Pullman to be analyzed by Watts, who then advises the best ways to remedy the mess. In a twist, one of those methods involves the use of sugar.
Watts, a pioneer in oxidizing systems for the detoxification of polluted soil and groundwater and a professor of civil and environmental … » More …
Salmon and other fish need cool, deep pools to spawn and survive in waterways like Washington’s Tucannon River. Washington State University researchers and their colleagues are measuring whether intentional logjams and stream reconstruction is creating better habitat for fish.
They saw in the water many of the serpent-kind, wondrous sea-dragons exploring the waters, such nicors as lie on the headlands, who, in the mornings, often accomplish sorrowful deeds on the sail-road, serpents and wild-beasts.
So concludes the epic poem Beowulf. Speaking Old English, storytellers composed Beowulf extemporaneously and shared passages from person to person for thousands of years until they were written down sometime between the eighth and the eleventh centuries. Beowulf is very much a poem about animals, so it’s appropriate to translate its last word, “wilde-or,” as “wild-beasts,” though the … » More …
