    Can science build a better burger?

    This isn’t as extreme as if the federal government had decided to regulate time travel. But it’s almost as surprising. The U.S. Food and Drug Administration is taking the first step toward rules for growing nutritious, delicious, juicy meat in labs, not farms.

    The notion of growing, say, just the beef instead of the whole cow has been floating around since at least the 1890s. This sci-fi...

    HPV vaccine as cancer prevention is a message that needs to catch on

    Cancer prevention isn’t the first thing that comes to many parents’ minds when they consider vaccinating their preteens against human papillomavirus, or HPV. And the fact that HPV is transmitted sexually gives the vaccine more baggage than a crowded international flight. But what gets lost in the din is the goal of vaccination, to protect adolescents from infection with HPV types that are...

  • 50 years ago, humans could pick the oceans clean

    Seafood is exhaustible — Man is capable of using up the resources of the ocean … and if he is going to exploit them intelligently, he has a lot to learn…. The world’s annual fish catch went up from 23 million to 46 million tons between 1953 and 1963, and is now estimated at 50 million tons, but scientists do not expect it to double every decade indefinitely. — Science News, August 6, 1966...

    Seeing humans as superpredators

    To get a glimpse of a superpredator, just look in the mirror. Comparing hunting habits of mammals and fishes reveals humans as Earth’s most dangerous, oddball predator — one that targets adult prey in large numbers, a practice that can push populations into decline.

    Humans’ main prey are reproductive adults, the animals that replenish populations, explains conservation scientist Chris...

    Chikungunya is on the move

    A crippling virus has slipped its bonds in Africa and Asia and is invading whole new continents faster than people can learn to pronounce its name. In one decade, chikungunya (chihk-uhn-GUHN-yuh) fever has gone from an obscure tropical ailment to an international threat, causing more than 3 million infections worldwide. The virus has established itself in Latin America and may now have the...

    No-fishing scheme in Great Barrier Reef succeeds with valuable fishes

    An ambitious, hotly debated system of no-take reserves inside the Great Barrier Reef Marine Park has boosted the population of its most commercially valuable fishes, says the first 10-year progress report.

    Coral trout (Plectropomus species) are now more common and bigger in protected spots than in comparable places still being fished, researchers say online March 26 in Current Biology....

    Tomorrow’s catch

    There’s something fishy going on with Pacific sardines. The pint-size swimmers, whose abundance sustained California’s famed Cannery Row for decades, all but disappeared from coastal waters in the 1950s. Numbers remained low until the late 1980s, when enough fish finally reappeared to make commercial harvesting worthwhile again. By then, sardines in the highly productive California Current...

    Creativity offers insights into the past and future

    Viewed through the window of an airplane, the Colorado River just seems so unlikely. On a cross-country flight this New Year’s Day, I watched as the snow-covered Rockies gave way to pancaked expanses of red rock. At its headwaters in the mountain foothills, the Colorado makes sense. But as I watched it flow through the deep scars that its waters had carved into a desiccated landscape, the...

    Few Americans eat right

    The Institute of Medicine periodically issues recommendations on what people should eat to be healthy and maintain a reasonable weight. Americans have largely ignored this well-intentioned advice, a new study shows. It reports that “nearly the entire U.S. population consumes a diet that is not on par with recommendations.”

    Most people missed the mark on nearly every...
