    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...

    Would you opt to see the future or decipher the past?

    Wouldn’t it be brilliant if every scientist had a crystal ball? It’s a question that came to me while reading Alexandra Witze’s story “What the Pliocene epoch can teach us about future warming on Earth.” Witze discusses how scientists are studying a warming period some 3 million years ago to try to understand how Earth will handle rising temperatures. The geologic epoch, known as the...

    What the Pliocene epoch can teach us about future warming on Earth

    Imagine a world where the polar ice sheets are melting, sea level is rising and the atmosphere is stuffed with about 400 parts per million of carbon dioxide. Sound familiar? It should. We’re living it. But the description also matches Earth a little over 3 million years ago, in the middle of the geologic epoch known as the Pliocene.

    To understand how our planet might respond as global...

    Luhan Yang strives to make pig organs safe for human transplants

    Luhan Yang, 31BiologisteGenesis

    Biologist Luhan Yang dreams of pig organs that will one day fly — into people. If she has her way, animal farms will raise herds of bioengineered pigs, designed to produce kidneys, livers and other organs that could be transplanted into humans. Animal parts would slip seamlessly into people, easing their suffering.

    “There are millions of patients...

    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...

    How earthquake scientists eavesdrop on North Korea’s nuclear blasts

    On September 9 of last year, in the middle of the morning, seismometers began lighting up around East Asia. From South Korea to Russia to Japan, geophysical instruments recorded squiggles as seismic waves passed through and shook the ground. It looked as if an earthquake with a magnitude of 5.2 had just happened. But the ground shaking had originated at North Korea’s nuclear weapons test site...

    Readers question climate’s freshwater effects

    Water woes

    A recent survey of lakes around the globe found that from 1985 to 2009, most warmed while only several cooled, Alexandra Witze reported in “In hot water” (SN: 5/13/17, p. 18). Rising temperatures have consequences for every part of a lake’s food web, from algae to walleye to freshwater seals.

    “This article indicates that no pattern could be found to predict which lakes...

    Lakes worldwide feel the heat from climate change

    About 40 kilometers off Michigan’s Keweenaw Peninsula, in the waters of Lake Superior, rises the stone lighthouse of Stannard Rock. Since 1882, it has warned sailors in Great Lakes shipping lanes away from a dangerous shoal. But today, Stannard Rock also helps scientists monitor another danger: climate change.

    Since 2008, a meteorological station at the lighthouse has been measuring...

    Readers amazed by Amasia

    Saved by the Bell

    Physicists used light from stars to perform a cosmic Bell test, which verified that quantum particles were indeed “spooky,” Emily Conover reported in “Quantum effect passes space test” (SN: 1/21/17, p. 12).

    Reader George Mitchell took issue with Conover’s description of entangled photons before they are measured as having multiple polarizations at once. “We don’t...
