    These cyborg beetles walk the walk

    Resistance may soon be futile. With machine implants worthy of a Star Trek villain, a new breed of beetle takes walking instructions from its human overlords.

    Hirotaka Sato and his colleagues at Nanyang Technological University in Singapore inserted electrodes into flower beetles (Mecynorrhina torquata) to stimulate specific leg muscle groups. By altering the order...

    Nuclear fusion gets boost from private-sector startups

    The lab where a company called General Fusion is trying to spark an energy revolution looks like a cross between a hardware store and a mad scientist’s lair. Bins full of electrical gadgets are piled high against the walls. Capacitors recycled from a bygone experiment are stacked up like bottles in wine racks. Ten-foot-high contraptions bristle with tangled wires and shiny plumbing.

    The ice of a distant moon

    View the video

    On an unusually hot summer day in Wales, Sanjay Vijendran and colleagues aimed a rocket sled at an elephant-sized ice cube.

    The sled rested on a raised metal track and carried what looked like a cartoon bundle of TNT to propel the contraption at the speed of sound. In front of it, a second sled held a bullet-shaped canister packed with scientific instruments.

    Your fear is written all over your face, in heat

    What gets us hot can be so revealing. For me, the slightest anxiety or excitement can trigger a warm spread across my face. I can feel the blood rushing up my neck and into the thousands of tiny capillaries across my cheeks. I’ve worn scarves or turtlenecks to job interviews, weather be damned, to keep my burning red neck from betraying my nerves.

    And the opposite can be true. Have you...

    When birds collide

    In “Collision course” (SN: 9/21/13, p. 20), Susan Milius told the stories of two ornithologists working to develop windows that birds won’t fly into.

    With few exceptions, readers were sympathetic to the plight of birds that either don’t see windows or incorrectly interpret reflections. William Thompson e-mailed about his Colorado home: “At the height of bird activity,...

    Sparing the rare earths

    The Toyota Prius isn’t exactly a muscle car. But the magnets under the hood certainly pack a punch.

    Pound for pound, these permanent magnets are some of the most powerful on the planet. They generate fields 10 times stronger than those of typical refrigerator magnets, helping the hybrid car’s motor and generator to turn the wheels and charge the...

    Newfound water risk: Lead-leaching valves

    Hidden elements in drinking-water lines can shed large amounts of lead, a toxic heavy metal. And it's quite legal, even if it does skirt the intent of federal regulations.

    University researchers, who uncovered this problem the hard way, have published a case study on the offending hardware in the November issue of the journal of the American Water Works Association.

    Sperm whales may team up to herd prey

    PORTLAND — Sperm whales sometimes collaborate when they forage the depths, new tracking data suggest, with some individuals herding prey into dense schools while others lunge into the fray and feed.

    Scientists have long known that sperm whales, like many other toothed whales, form long-lasting social groups that typically consist of females and their young. While some...
