    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...

    China is about to visit uncharted territory on the moon

    China is about to make space history. In December, the country will launch the first spacecraft ever to land on the farside of the moon. Another craft, slated for takeoff in 2019, will be the first to bring lunar rocks back to Earth since 1976.

    These two missions — the latest in China’s lunar exploration series named after the Chinese moon goddess, Chang’e — are at the forefront of...

  • 50 years ago, atomic testing created otter refugees

    Sea otters restocked in old home

    When the [Atomic Energy Commission] first cast its eye on the island of Amchitka as a possible site for the testing of underground nuclear explosions, howls of anguish went up; the island is part of the Aleutians National Wildlife Refuge, created to preserve the colonies of nesting birds and some 2,500 sea otters that live there…— Science News, ...

    ‘End of the Megafauna’ examines why so many giant Ice Age animals went extinct

    End of the MegafaunaRoss D.E. MacPhee and Peter Schouten (illustrator)W.W. Norton & Co., $35

    Today’s land animals are a bunch of runts compared with creatures from the not-too-distant past. Beasts as big as elephants, gorillas and bears were once much more common around the world. Then, seemingly suddenly, hundreds of big species, including the woolly mammoth, the giant ground...

    Malaysia is ground zero for the next malaria menace

    Vinita Surukan knew the mosquitoes were trouble. They attacked her in swarms, biting through her clothes as she worked to collect rubber tree sap near her village in Sabah, the northern state of Malaysia. The 30-year-old woman described the situation as nearly unbearable. But she needed the job.

    There were few alternatives in her village surrounded by fragments of forest reserves and...

    Screen time to heal, and perhaps to harm

    In any given year, nearly 20 percent of U.S. adults, more than 40 million people, have to contend with a mental illness. Getting treatment is often a struggle; fewer than half of those affected get any sort of care, which can be especially hard to find in rural and underserved communities.

    Virtual reality may seem like the least likely technology to address the lack of mental health...

    Questions about toxic red tides, and more reader feedback

    Hot stuff

    A new material that converts sunlight into heat could someday melt ice off airplane wings, wind turbines and rooftops, Maria Temming reported in “A new material harnesses light to deice surfaces” (SN: 9/29/18, p. 17).

    “What happens when the object (such as an airplane wing) to which the material has been applied is subjected to the sun on a hot summer day?” asked online...

    Vanadium dioxide’s weird phase transition just got weirder

    For the first time, researchers have gotten a detailed view of how atoms in a compound called vanadium dioxide move when an ultrafast laser pulse transforms the material from an electrical insulator to a conductor — and it’s nothing like scientists expected.

    Rather than switching from one crystal formation to another in a direct, synchronized manner, like choreographed ballerinas, the...

    The Milky Way feasted on a smaller galaxy 10 billion years ago

    In its younger days, the Milky Way devoured a smaller galaxy, and stars from the hapless victim still roam the skies today to tell the tale, a new study finds.

    “This is a major event in the history of the galaxy,” says astronomer Amina Helmi of the University of Groningen in the Netherlands. “We’re really starting to probe the ancestors of the Milky Way.”

    Helmi and her colleagues...
