Gamma-Ray Bursts: Flashes in the Sky

Gamma-ray bursts—flashes of intense radiation in space that are often just seconds long—were accidentally discovered in the 1960's by satellites built to monitor nuclear bomb explosions. They've been one of the leading astrophysical mysteries ever since. This Astro Bulletin introduces you to the scientists and instruments working to unravel the origins of gamma-ray bursts. It highlights Swift, NASA's burst-detecting satellite, and PAIRITEL, one of a fleet of ground-based telescopes that point toward a gamma-ray burst in response to Swift's alert to capture the afterglow before it fades. Astrophysicists at Penn State and other institutions are analyzing these afterglows to understand what causes the most powerful explosions known

Trails in the Snow: The Effects of Reforestation on Mammal Distribution in the Baraboo Hills

The first snowfalls of winter have transformed the landscape into a pristine, silent, unscathed world. The sounds of birds and animals that are so casual in other seasons are now magnified by silence. The bark of a squirrel is crisp and suspended in time, like the lingering imprint her paws leave on the snow.  Winter is the invigorating cold, the silent struggles for survival, the stories written by paws and hooves on the snow; small details that could easily not be noticed.
