    Flying insects tell tales of long-distance migrations

    Every autumn, a quiet mountain pass in the Swiss Alps turns into an insect superhighway. For a couple of months, the air thickens as millions of migrating flies, moths and butterflies make their way through a narrow opening in the mountains. For Myles Menz, it’s a front-row seat to one of the greatest movements in the animal kingdom.

    Menz, an ecologist at the University of Bern in...

    False alarms may be a necessary part of earthquake early warnings

    Earthquake warning systems face a tough trade-off: To give enough time to take cover or shut down emergency systems, alerts may need to go out before it’s clear how strong the quake will be. And that raises the risk of false alarms, undermining confidence in any warning system.

    A new study aims to quantify the best-case scenario for warning time from a hypothetical earthquake early...

    When bogs burn, the environment takes a hit

    In 2015, massive wildfires burned through Indonesia, sending thick smoke and haze as far as Thailand.

    These fires were “the worst environmental disaster in modern history,” says Thomas Smith, a wildfire expert at King’s College London. Smith estimates that the fires and smoke killed 100,000 people in Indonesia and neighboring countries and caused billions of...

    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...

    Hormone replacement makes sense for some menopausal women

    Internist Gail Povar has many female patients making their way through menopause, some having a tougher time than others. Several women with similar stories stand out in her mind. Each came to Povar’s Silver Spring, Md., office within a year or two of stopping her period, complaining of frequent hot flashes and poor sleep at night. “They just felt exhausted all the time,” Povar says. “The joy...

    To understand the origins of pain, ask a flatworm

    Hydrogen peroxide, a molecule produced by cells under duress, may be a common danger signal, helping to alert animals to potential harm and send them scurrying. New details from planarian flatworms of how this process works may deepen scientists’ understanding of how people detect pain, and may ultimately point to better ways to curb it.

    “Being able to get a big-picture view of how these...

    Machines are getting schooled on fairness

    You’ve probably encountered at least one machine-learning algorithm today. These clever computer codes sort search engine results, weed spam e-mails from inboxes and optimize navigation routes in real time. People entrust these programs with increasingly complex — and sometimes life-changing — decisions, such as diagnosing diseases and predicting criminal activity.

    Machine-learning...

    Rumors swirl that LIGO snagged gravitational waves from a neutron star collision

    View the video

    Speculation is running rampant about potential new discoveries of gravitational waves, just as the latest search wound down August 25.

    Publicly available logs from astronomical observatories indicate that several telescopes have been zeroing in on one particular region of the sky, potentially in response to a detection of ripples in spacetime by the Advanced Laser...

    Expert eavesdroppers occasionally catch a break

    In July of 1972, NASA launched the first Landsat satellite into orbit around Earth. Since then, the spacecraft and its successors have transformed our understanding of Antarctica (and the rest of the planet, too). In the first year following the launch, Landsat’s images of the faraway continent showed “uncharted mountain ranges, vast ice movements and errors in maps as little as two...
