Capsules of Chemicals

Insecticides show more toxicity inside tiny pellets

Packaging certain insecticides inside tiny plastic pellets may amplify their toxicity in the environment, a new study suggests. The same chemical used naked — suspended only in water — was significantly less toxic than its capsulated counterpart, researcher Stacy Harper reported recently in the journal Environment International. The chemical in question (a “pyrethroid” whose active […]

Undersea Gliders Think Like a Fish

Sensors will shed light on ocean ecology

  BY EQUIPPING UNDERWATER GLIDERS with acoustic sensors and computer software, Oregon State oceanographers are teaching the autonomous vehicles to identify biological hot spots in the oceans. “We want to get a better handle on what kind of marine animals are out there, how many there are, where they are distributed and how they respond […]

Aspen Recovery in Yellowstone Spurred by Wildlife Shifts

Wildlife in Yellowstone National Park is undergoing dramatic shifts with consequences that are beginning to return the landscape to conditions not seen in nearly a century. In the park’s northeast section, elk have decreased in number in their historic winter range in the Lamar Valley and are now more numerous outside the park. Aspen recovery […]
