A University of Washington (UW) survey of pollution and other impurities in North American snow required researchers to find sites with undisturbed snow far from any city or major road – in other words, a recipe for getting stranded by the side of a cold, lonely road.

Late summer is the peak time for harmful algae that can turn lakes into toxic scum, canceling fishing trips and fouling water supplies. While the Pacific Northwest doesn’t get anything near the activity that turned parts of Lake Erie into bright green slime, our coasts are vulnerable in late summer to this largely unpredictable – and in our case unseen – menace.

When startled by predators, tiny fruit flies respond like fighter jets – employing screaming-fast banked turns to evade attacks.

Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy efficient.
