    This new fish species displays a splash of highlighter hues

    A new species of reef fish is a real head turner. 

    Last year while surveying a remote coral reef about 130 meters below the surface of the Atlantic Ocean, ichthyologists Luiz Rocha and Hudson Pinheiro spotted a radiant fish hiding in a drab rock crevice.  

    “It was like finding a bright emerald in a coal mine,” recalls Pinheiro.

    The fish, with its electric-pink-and-yellow body...

    How math helps explain the delicate patterns of dragonfly wings

    The dainty veins gracing the wings of dragonflies and other insects are like fingerprints: Each wing displays a distinct pattern. A randomized mathematical process may help explain how certain thin filaments, called secondary veins, form these complex patterns, a new study finds.

    Insect wings consist of two types of veins, both of which provide structural support (SN: 6/24/17, p. 5)....

    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...

    This flying robot could reveal secrets of the aerial world of insects

    A new winged robot helps explain why airborne insects are so doggone hard to swat.

    Scientists have wondered how these tiny pilots pull off such rapid twists and turns, but researchers haven’t been able to test all their ideas by monitoring real insects or using tethered robots. Now, a free-flying, insect-inspired robot, described in the Sept. 14 Science, gives researchers an alternative...

    Before it burned, Brazil’s National Museum gave much to science

    A natural history museum isn’t just a place to take visiting relatives or for entertaining kids on the weekends. These museums’ collections also play a vital, but under-celebrated, role in scientific research.

    That’s why, when Brazil's National Museum in Rio de Janeiro caught fire on September 2, more than just a catalog of natural and human history was lost. The museum was full of...

    These songbirds violently fling and then impale their prey

    Bite a mouse in the back of the neck and don’t let go. Now shake your head at a frenzied 11 turns per second, as if saying “No, no, no, no, no!”

    You have just imitated a hunting loggerhead shrike (Lanius ludovicianus), already considered one of North America’s more ghoulish songbirds for the way it impales its prey carcasses on thorns and barbed wire.  

    Once the shrike hoists its...

    A gentoo penguin’s dinner knows how to fight back

    In a fight between a pipsqueak and a giant, the giant should always win, right?

    Well, a battle between an underwater David and Goliath has revealed that sometimes the little guy can come out on top. He just needs the right armaments. The David in this case is the lobster krill. And instead of a slingshot, it’s armed with sharp pincers that can sometimes fight off a Goliath: the gentoo...

    As temperatures rise, so do insects’ appetites for corn, rice and wheat

    With temperatures creeping up as the climate warms, those very hungry caterpillars could get even hungrier, and more abundant. Crop losses to pests may grow.

    Insects will be “eating more of our lunch,” says Curtis Deutsch of the University of Washington in Seattle. Based on how heat revs up insect metabolism and reproduction, he and his colleagues estimate that each degree Celsius of...

    Naked mole-rats eat the poop of their queen for parenting cues

    Dealing with poop is an unavoidable hazard of raising children, regardless of species. But for naked mole-rats, that wisdom is especially salient.

    During pregnancy, the scat of a naked mole-rat queen — the only female in the colony that reproduces, giving birth to a few dozen pups each year — contains high levels of the sex hormone estradiol. When subordinate female naked mole-rats eat...
