    Mother lode

    A bonanza of potent disease-fighting compounds has been discovered in a surprisingly common source — the breasts of every nursing mother on the planet. Human milk, the only substance that evolved to feed and protect us, seems to contain a trove of medicines just now being unlocked by scientists.

    “We go down to the bottom of the ocean to find new compounds and test them out against...

    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...

    Debates over definition of planet continue and inspire

    Planetary science is in the midst of a revolution. As recently as the early 1990s, “the planets” consisted of just nine famous objects in our solar system that every school kid learned to recognize by name and appearance. But then, advances in astronomical technology unleashed an explosion of new planetary discoveries on two fronts.

    One of these fronts involved a bewildering variety of...

    Machu Picchu’s far-flung residents

    High in Peru’s Andes, the skeletons of people buried at the famous Inca site of Machu Picchu tell a tale of displacement and devoted service. A new chemical analysis of these bones supports the previously postulated idea that Inca kings used members of a special class of royal retainers from disparate parts of the empire to maintain and operate the site, which served as a royal estate.

    Nurturing Our Microbes

    Each of us is a metropolis. Bustling about in everyone's body are tens of trillions of microbes. Some are descended from starter populations provided by mom during birth. Additional bacteria, yeasts, and other life forms hitchhike in with foods. By age 3, everyone's gut hosts a fairly stable, yet diverse, ecosystem.

    Most of the tiny stowaways hide out in the...

    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. The late-April scene occurs as, throughout the northern Midwest, water...

    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...

    Gadgets from the Quantum Spookhouse

    Computers exploiting the oddities of quantum mechanics may eventually put conventional computers to shame. Theoretically, full-fledged versions of those quantum machines will someday master in an eye blink mathematical puzzles and secret codes that current supercomputers wouldn't crack with a billion years of number crunching.

    The exotic innards of such quantum computers...
