    The Southern Ocean may be less of a carbon sink than we thought

    The vast stretch of icy water that separates Antarctica from other continents is a dark mystery to most people. Polar explorer Ernest Shackleton, one of the few who have been to the Southern Ocean, regarded its storm-wracked seas with fear and awe. After ice floes trapped and crushed the three-masted Endurance in 1915, Shackleton made an epic rescue attempt, sailing 1,300 kilometers to bring...

    How mammoths competed with other animals and lost

    The Gray Fossil Site, a sinkhole in northeastern Tennessee, is full of prehistoric treasures. Between 7 million and 4.5 million years ago, rhinoceroses, saber-toothed cats and other creatures, even red pandas, perished here by the edge of a pond. But that bounty of fossils pales next to the site’s biggest find: a mastodon’s skeleton, nearly 5 million years old, preserved in exquisite detail...

    More than 2 billion people lack safe drinking water. That number will only grow.

    Freshwater is crucial for drinking, washing, growing food, producing energy and just about every other aspect of modern life. Yet more than 2 billion of Earth’s 7.6 billion inhabitants lack clean drinking water at home, available on demand.

    A major United Nations report, released in June, shows that the world is not on track to meet a U.N. goal: to bring safe water and sanitation to...

    The trouble with water, be it too much or too little

    A year ago, while news reports focused on the inundation of Houston by Hurricane Harvey, much of the Indian city of Mumbai was also underwater. Both coastal cities, more than 14,000 kilometers apart, had been swamped by extreme rainfall. Deputy news editor Katy Daigle, who had reported from India for seven years for the Associated Press before joining Science News, knew that flooding...

    Here’s a look at the world’s deadliest volcanoes — and the ways they kill

    Guatemala’s Fuego volcano erupted explosively on June 3, sending hot gas and rock racing downhill in what’s known as a pyroclastic flow. At least 69 people were killed. Emergency officials are trying to reach buried villages to assess the scope of the disaster, but Fuego is already the world's deadliest eruption of 2018.

    The tragedy offers a grim reminder of the many dangers posed by...

    Readers respond to pesticides, Hawking radiation and more

    Pesky pesticides

    Researchers are tracking tiny insects to learn how animals move around the planet, Alexandra Witze reported in “Flying insects tell tales of long-distance migrations” (SN: 4/14/18, p. 22).

    “There are several uncritical references to using pesticides to combat insect pests” in the story, reader Christina Gullion wrote.

    Gullion noted that pesticides can be...

    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...
