    Resurrecting woolly mammoth cells is hard to do

    Proteins from woolly mammoth cells frozen for 28,000 years in the Siberian tundra may still have some biological activity, claim researchers attempting to clone the extinct behemoths.

    Japanese scientists first extracted nuclei, the DNA-containing compartments of cells, from the muscles of a juvenile woolly mammoth called Yuka, discovered in 2010 in northeast Russia. The team then...

    A massive crater hides beneath Greenland’s ice

    There’s something big lurking beneath Greenland’s ice. Using airborne ice-penetrating radar, scientists have discovered a 31-kilometer-wide crater — larger than the city of Paris — buried under as much as 930 meters of ice in northwest Greenland.

    The meteorite that slammed into Earth and formed the pit would have been about 1.5 kilometers across, researchers say. That’s large enough to...

    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...

    ‘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...

    Why won’t this debate about an ancient cold snap die?

    Around 13,000 years ago, Earth was emerging from its last great ice age. The vast frozen sheets that had covered much of North America, Europe and Asia for thousands of years were retreating. Giant mammals — steppe bison, woolly mammoths and saber-toothed cats — grazed or hunted across tundra and grasslands. A Paleo-Indian group of hunter-gatherers who eventually gave rise to the Clovis people...

    Readers debate ethics of resurrecting extinct species

    Culture club

    The book Rise of the Necrofauna tackles the challenges of using gene-editing tools to bring woolly mammoths and other long-gone species back from the dead. These “de-extincted” creatures would have to contend with a radically changed world that includes new habitats and diseases, Tina Hesman Saey wrote in her review “Resurrecting extinct species raises ethical questions” (SN:...

    What male bias in the mammoth fossil record says about the animal’s social groups

    Male mammoths really had to watch their steps. More than two-thirds of woolly mammoth specimens recovered from several types of natural traps in Siberia came from males, researchers report November 2 in Current Biology.

    Paleogenomicist Patrícia Pečnerová of the Swedish Museum of Natural History in Stockholm and her colleagues examined genomic data recovered from 98 mammoth bone, tooth,...

    Resurrecting extinct species raises ethical questions

    Rise of the NecrofaunaBritt WrayGreystone Books, $26.95

    A theme park populated with re-created dinosaurs is fiction. But if a handful of dedicated scientists have their way, a park with woolly mammoths, passenger pigeons and other “de-extincted” animals could become reality.

    In Rise of the Necrofauna, writer and radio broadcaster Britt Wray presents a comprehensive look...

    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...
