A Slippery Slope

Grinding over ancient layers of lava and ash, the glaciers of the Cascade Range act like supersized sheets of shrinkwrap.

Stones on Ice

Why should the residents of Seattle, San Francisco, New York City and Boston worry about warming in Greenland, an ice-laden island in the North Atlantic? Because if all the water locked in the massive Greenland Ice Sheet flowed into the oceans, low-lying coastal cities worldwide would be inundated.

Regulating Immunity: Toxicologists seek novel gene therapies

Dioxin, the chemical pollutant made infamous by Vietnam-era defoliant Agent Orange, has long been known to suppress immune function in humans and other animals. Surprisingly, this dangerous side effect has a scientific silver lining. While studying the toxin’s health effects, researchers discovered the genetic pathway to immune system malfunction. For people who would actually benefit from suppressed immunity — those suffering from autoimmune and allergic diseases — this clue may lead to better therapies.
