    DNA from seized elephant ivory unmasks 3 big trafficking cartels in Africa

    Pairs of elephant tusks that are separated during smuggling are illuminating the tracks of wildlife crime.

    Identifying matching elephant DNA in different shipments of tusks can help scientific sleuths connect the shipments to the same ivory trafficking cartel, a new study finds. That technique has already revealed the presence of three major interconnected cartels that are active in...

    ‘Poached’ offers a deep, disturbing look into the illegal wildlife trade

    PoachedRachel Love NuwerDa Capo Press, $28

    Perhaps the most unsettling scene in Poached, by science journalist Rachel Love Nuwer, comes early in the book, in a fancy restaurant in Ho Chi Minh City, Vietnam. The author and two friends sit down and are handed leather-bound menus offering roasted civet, fried tortoise, stewed pangolin and other delicacies made from rare or endangered...

    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...

    With one island’s losses, the king penguin species shrinks by a third

    What was once the king of the king penguin colonies has lost 85 percent or more of its big showy birds since the 1980s, a drop perhaps big enough to shrink the whole species population by a third.

    In its glory days, an island called Île aux Cochons in the southern Indian Ocean ranked as the largest colony of king penguins. Satellite data suggest numbers peaked at around 500,000 breeding...

    Got an environmental problem? Beavers could be the solution

    EagerBen GoldfarbChelsea Green Publishing, $24.95

    Most people probably don’t think of beavers until one has chewed through the trunk of a favorite tree or dammed up a nearby creek and flooded a yard or nearby road. Beavers are pests, in this view, on par with other members of the order Rodentia. But a growing number of scientists and citizens are recognizing the merits of these...

    Researchers create hybrid embryos of endangered white rhinos

    The nearly extinct northern white rhino may not be completely lost.

    For the first time, white rhinoceros embryos have been made in the lab. Scientists injected preserved sperm from a male northern white rhino into eggs of female southern white rhinos, a closely related subspecies. The embryos were incubated until the cells began to differentiate, a stage at which they can be implanted...

    Madagascar’s predators are probably vulnerable to toxic toads

    At some point eight to 10 years ago, some toads stowed away on a ship in Asia, possibly Ho Chi Minh City, and hitched a ride to Madagascar. Those invaders, Asian common toads, have been slowly spreading across the large island ever since.

    The toad’s skin contains a toxin that kills nearly anything that tries to eat the amphibian. Scientists have been warning of the toad’s danger to...

    Here’s what narwhals sound like underwater

    Narwhals are among the most elusive of whales. But for the first time, researchers have been able to eavesdrop on the creatures for days at a time as these unicorns of the sea dove, fed and socialized.

    Biologist Susanna Blackwell and colleagues listened in on the clicks, buzzes and calls of the East Greenland narwhal (Monodon monoceros). The team’s findings, published June 13 in PLOS ONE...

    In a conservation catch-22, efforts to save quolls might endanger them

    Conservationists are stuck in a catch-22: In trying to save some species, the would-be protectors may be giving the animals an evolutionary disadvantage. A new study describes how efforts to protect the endangered northern quoll, a spotted, kitten-sized marsupial native to Australia, by placing a population on a threat-free island may have actually undermined a key survival instinct.

  • 50 years ago, scientists warned of a sparrow’s extinction

    The dwindling dusky

    In the marshes around America’s spaceport, Kennedy Space Center, live the last few specimens of a bird that may be closer to extinction than even the much-mourned whooping crane. While the whooper might make a gradual comeback if protected and left alone, the dusky seaside sparrow is as good as dead unless man steps in to lend an active hand. — Science News, May...
