    Measuring Tsunamis

    The NOAA took 20 years to develop a reliable tsunamograph, an apparatus that provides accurate, real-time data on tsunamis. It consists of an anchored, ocean-bottom pressure recorder and a companion buoy (called DART, for Deep-Ocean Assessment and Reporting of Tsunamis). The recorder, sitting at a depth of up to 5,000 meters, measures changes in pressure due to changes in water level. The recorder transmits acoustic signals to the buoy, which, in turn, relays the measurements of wave height to satellites. This information is then used to forecast the progress of a tsunami. Although each tsunamograph costs a mere $200,000, there are only about 50 in operation worldwide. There are scarcely any in the middle of the Pacific, and practically none in the Indian Ocean. Each dot on the map above represents a single buoy, an object about five feet wide that resembles a flying saucer. Many countries, such as India and Indonesia, have resisted acquiring DARTs from the NOAA out of a sense of ...

    Dictator-Proofing the Internet

    When authorities in Egypt shut down Internet connections during last week’s uprising, hackers around the world started scrambling to create a work-around. Before they could succeed, the blackout was lifted. But now people are worried that similar shutdowns might occur in countries like Jordan, Syria, and Yemen—and so hackers are working to set up alternative networks in those countries, just in case.

    Why Some People Choose Anxiety

    Considering that anxiety makes your palms sweat, your heart race, your stomach turn somersaults, and your brain seize up like a car with a busted transmission, it’s no wonder people reach for the Xanax to vanquish it. But in a surprise, researchers who study emotion regulation—how we cope, or fail to cope, with the daily swirl of feelings—are discovering that many anxious people are bound and determined (though not always consciously) to cultivate anxiety. The reason, studies suggest, is that for some people anxiety boosts cognitive performance, while for others it actually feels comforting.

    It sounded like a panacea for climate change: “geo-engineering” the atmosphere to block some sunlight and counter global warming.

    Why Almost Everything You Hear About Medicine Is Wrong

    If you follow the news about health research, you risk whiplash. First garlic lowers bad cholesterol, then—after more study—it doesn’t. Hormone replacement reduces the risk of heart disease in postmenopausal women, until a huge study finds that it doesn’t (and that it raises the risk of breast cancer to boot). Eating a big breakfast cuts your total daily calories, or not—as a study released last week finds. Yet even if biomedical research can be a fickle guide, we rely on it.

    What an Apple Without Steve Jobs Might Look Like

    Apple CEO Steve Jobs has gone on a medical leave. With luck this will be temporary, like his last medical leave, in 2009, when Jobs, a survivor of pancreatic cancer, received a liver transplant. But what if he doesn’t come back? Ever since the previous time, people have wondered if the company could carry on without him.
