    Restoring Scents

    Betty (not her real name) remembers the day 9 years ago when she fully experienced an orange. As she split the fruit's skin, citrus scents sprayed into the air and the 51-year-old woman experienced a sensory epiphany: "Whoa! This is an orange. My God, this is what an orange smells like."

    Even now, she says, recalling that day "makes me tear up because that orange...

    New Estimates of the Shark-Fin Trade

    Immense numbers of sharks each year are slaughtered for their fins—not meat, just their fins. This harvest helps feed a growing appetite throughout Asia for a popular soup, one with snob appeal comparable to that of caviar. Indeed, a single bowl of shark-fin soup can cost $100 in a high-end Hong Kong restaurant.

    The key ingredient of shark-fin soup is...

    Pick Your Antipoison

    On a warm, sunny afternoon last June, emergency room physician Sean Bush got a call on his pager that made his blood run cold. The number was his wife's, followed by three digits: 9-1-1. Whatever the page concerned, Bush knew that it was a serious emergency—he and his wife don't take those numbers lightly.

    A quick call from the hospital where he was on duty to his home 22...

    Fish as Farmers: Reef residents tend an algal crop

    A damselfish cultivates underwater gardens of an algal species that researchers haven't found growing on its own.

    The special alga could be the fishy version of people's domesticated crops, says Hiroki Hata of Kyoto University in Japan. Growth tests of the alga, surveys of its distribution, and genetic analyses support that idea, he and Makoto Kato say in an upcoming Biology...

    Violent Developments

    Henry was headed for serious trouble. The 15-year-old provoked an endless series of fights at school and frequently bullied girls. Teachers regularly suspended him for his classroom disruptions. Older students taunted Henry in the hallways by calling him a sexual pervert or jeered him for having been held back in kindergarten. At home, his father browbeat and denigrated the boy, while his...

    Wary male spiders woo lifelessly

    Certain male spiders confront the threat of a cannibalistic female with a novel tactic: They play dead while having sex.

    Nursery spiders (Pisaura mirabilis) belong to a family known for violent females that, on occasion, attack and eat males attempting courtship, notes Trine Bilde of Århus University in Denmark.

    Biologists already knew that males of this species have one method...

    Easy Answers: Quantum computer gives results without running

    Physicists have long known that quantum computers have the potential to race through calculations trillions of times as fast as ordinary computers do. Now, it seems that those machines may not have to calculate at all to deliver answers.

    That seemingly absurd possibility, which was advanced as a theory several years ago, has now received experimental verification. What's more, although...

    Quantum Chip: Device handles ions as if they were data

    Physicists have created a microchip that can hold an electrically charged atom and move it back and forth within a narrow channel. These manipulations lay the groundwork for using trapped ions as data bits in computer chips, the developers of the new device say.

    The scientists created the chip as a step toward a new breed of computers, called quantum computers, which represent...

    Champion of strength is forged in mighty anvil

    A newly created form of carbon has captured the crown of world's strongest known material. A team of researchers in Germany and France made the new material using a specialized, multijawed anvil that simultaneously squeezed and heated a powder of all-carbon molecules known as buckyballs.

    At 200,000 times atmospheric pressure and a temperature of 2,500 kelvins, the powder...

    Armor-Plated Puzzle

    A few years after Francis H. Crick and James D. Watson unveiled the structure of DNA in 1953, they rocked the fledgling field of molecular biology again with a bold notion: Viruses are, in part, structured as crystals are. That idea captivated Donald L.D. Caspar and Aaron Klug, who then systematically applied what they knew about crystal geometry to classify and predict the structures that...
