    Biological invasion via Suez

    The Red Sea is invading the Mediterranean.… So far about 140 life-forms, mostly animal and mostly invertebrate, have crossed the Isthmus of Suez.… It is possible that this … will result in the loss of a few native fish and invertebrate populations to stiff competition from the newcomers. — Science News, March 30, 1968

    Earwigs take origami to extremes to fold their wings

    To quickly unfurl and refold their wings, earwigs stretch the rules of origami.

    Yes, those garden pests that scurry out from under overturned flowerpots can also fly. Because earwigs spend most of their time underground and only occasionally take to the air, they pack their wings into packages with a surface area more than 10 times smaller than when unfurled, using an origami-like series...

    How oral vaccines could save Ethiopian wolves from extinction

    Deep in the Bale Mountains of Ethiopia, wildlife workers trek up above 9,800 feet to save some of the world’s most rare carnivores, Ethiopian wolves.

    “It’s cold, tough work,” says Eric Bedin, who leads the field monitoring team in its uphill battle.

    In this sparse, sometimes snowy landscape, the lanky and ginger-colored wolves (Canis simensis) reign as the region’s apex predators....

    Dino-bird had wings made for flapping, not just gliding

    Archaeopteryx was a flapper, not just a glider. The shape of the ancient bird’s wing bones suggests it was capable of short bursts of active, flapping flight, similar to how modern birds like pheasants and quails fly to escape predators, a new study finds.

    One of the earliest birds, Archaeopteryx lived about 150 million years ago during the Jurassic Period, spanning the evolutionary gap...

    Readers muse about memory, magnetic monopoles and more

    Memory lane

    Inspired by flatworm memory experiments from the 1950s, researchers are on the hunt for the elusive engram — the physical mark that a memory leaves on the brain — Laura Sanders reported in “Somewhere in the brain is a storage device for memories” (SN: 2/3/18, p. 22).

    Readers flooded Science News with their thoughts and questions on the topic.

    This baby bird fossil gives a rare look at ancient avian development

    This baby bird had barely hatched before it died 127 million years ago — and its lack of fully developed bony breastbone, or sternum, suggests it couldn’t yet fly. The tiny fossil, just a few centimeters long, is giving paleontologists a rare window into the early development of a group of extinct birds called Enantiornithes, researchers report March 5 in Nature Communications.

    Humans don’t get enough sleep. Just ask other primates.

    People have evolved to sleep much less than chimps, baboons or any other primate studied so far.

    A large comparison of primate sleep patterns finds that most species get somewhere between nine and 15 hours of shut-eye daily, while humans average just seven. An analysis of several lifestyle and biological factors, however, predicts people should get 9.55 hours, researchers report online...

    In a pack hunt, it’s every goatfish for itself

    The only fish known to hunt with wolf pack moves may not be true team players, just lemon-yellow me-firsts.

    Yellow saddle goatfish (Parupeneus cyclostomus) do more than school together as they dart over Indo-Pacific coral reefs. Like wolves, the goatfish take different roles in a pursuit. One or two fish may rush straight toward prey as the others shoot to the sides, blocking escape....

    By 2100, damaged corals may let waves twice as tall as today’s reach coasts

    A complex coral reef full of nooks and crannies is a coastline’s best defense against large ocean waves. But coral die-offs over the next century could allow taller waves to penetrate the corals’ defenses, simulations suggest. A new study finds that at some Pacific Island sites, waves reaching the shore could be more than twice as high as today’s by 2100.

    The rough, complex structures of...

    Penguin supercolony discovered in Antarctica

    On an expedition to an icy island chain off the Antarctic Peninsula’s northern tip, researchers discovered a massive supercolony of more than 1.5 million Adélie penguins, according to a study published March 2 in Scientific Reports.

    Scientists had known of an Adélie penguin colony (Pygoscelis adeliae) in these Danger Islands, but satellite images revealed more guano on the rocky islands...
