    Can you hear me now?

    The Earth is going silent. Digital television signals delivered by cable and satellite are quickly replacing analog broadcasts and reducing the number and power of radio waves leaking into space. For viewers at home, it means more channels and pictures of unsurpassed clarity. But for scientists seeking signs of advanced civilizations beyond the solar system, this sudden radio silence makes...

    Marine pollution spawns 'wonky babies'

    Wonky? It’s British slang for shaky, unreliable or unattractive. In Ceri Lewis’s lexicon, it refers to the odd, off-kilter embryonic development that can occur.

    Saving Sturgeon

    On a fine spring day alongside a Wisconsin river, several biologists wrestle a muscular, 120-pound fish onto her back and straddle her. The moves wouldn't be out of place in a rodeo. As the team restrains her, one member massages her swollen belly, working her eggs out of a release vent and into a plastic pail.

    Udder Beauty

    The scourge of udder tampering has not escaped the attention of humorist Dave Barry. In one of his columns, he laments unscrupulous dairy farmers who inject foreign udder-enhancing substances into their animals' mammary glands in a desperate bid for a competitive edge at livestock shows. Barry likens these competitions to human beauty pageants, except that the cows get no credit at all for...
