    Your phone is like a spy in your pocket

    Consider everything your smartphone has done for you today. Counted your steps? Deposited a check? Transcribed notes? Navigated you somewhere new?

    Smartphones make for such versatile pocket assistants because they’re equipped with a suite of sensors, including some we may never think — or even know — about, sensing, for example, light, humidity, pressure and temperature.

    Because...

    New technique could help spot snooping drones

    Now there’s a way to tell if a drone is spying on someone.

    Researchers have devised a method to tell what a drone is recording — without having to decrypt the video data that the device streams to the pilot’s smartphone. This technique, described January 9 at arXiv.org, could help military bases detect unwanted surveillance and civilians protect their privacy as more commercial drones...

    ‘First Face of America’ explores how humans reached the New World

    A teenage girl climbed into an underground cave around 13,000 years ago. Edging through the ink-dark chamber, she accidentally plunged to her death at the bottom of a deep pit.

    Rising seas eventually inundated the cave, located on Central America’s Yucatán Peninsula. But that didn’t stop scuba divers from finding and retrieving much of the girl’s skeleton in 2007.

  • 50 years ago, IUDs were deemed safe and effective

    IUDs: approval of a renaissance

    In 1929, the German scientist Ernst Grafenberg inserted silver rings into the uteri of 2,000 women, and reported a pregnancy rate of only 1.6 percent. Despite this history, the use of intrauterine devices, or IUDs, was not generally accepted.… A report made public last week by the FDA’s Advisory Committee on Obstetrics and Gynecology concludes that...

    A sinking, melting ancient tectonic plate may fuel Yellowstone’s supervolcano

    The driving force behind Yellowstone’s long and explosive volcanic history may not be as deep as once thought. A new study suggests that instead of a plume of hot mantle that extends down to Earth’s core, the real culprit is a subducting tectonic plate that began sinking beneath North America hundreds of millions of years ago.

    Computer simulations show that movement of broken-up remnants...

  • 50 years ago, synthetic DNA made its debut

    Viable synthetic DNA

    [Scientists] produced in a test tube a totally artificial copy of a type of DNA virus.… The particular type of viral DNA (called Phi X174) the researchers made is an extremely simple molecule of only five or six genes. Their achievement, however, lays the foundation for eventual synthesis of more complex DNAs. — Science News, December 30, 1967

    Tiny trackers reveal the secret lives of young sea turtles

    View the video

    Not so long ago, the lives of sea turtles were largely a mystery. From the time that hatchlings left the beaches where they were born to waddle into the ocean until females returned to lay their eggs, no one really knew where the turtles went or what they did.

    Then researchers started attaching satellite trackers to young turtles. And that’s when scientists...

    The sun’s outer atmosphere is far more complex than previously thought

    NEW ORLEANS — Despite its smooth appearance, the sun’s wispy outer atmosphere is surprisingly full of knots, whorls and blobs.

    Newly analyzed observations from NASA’s STEREO spacecraft show that the sun’s outer corona is just as complicated as the highly structured inner corona, solar physicists reported December 12 at the fall meeting of the American Geophysical Union. That previously...
