    Hemp fields offer a late-season pollen source for stressed bees

    VANCOUVER — Fields of hemp might become a late-season pollen bonanza for bees.

    Industrial hemp plants, the no-high varieties of cannabis, are becoming a more familiar sight for American bees as states create pilot programs for legal growing. Neither hemp nor the other strains of the Cannabis sativa species grown for recreational or medicinal uses offer insects any nectar, and all rely on...

    Wombats are the only animals whose poop is a cube. Here’s how they do it.

    Of all the poops in the world, only wombats’ are shaped like cubes.

    The varied elasticity of the wombat’s intestines helps the marsupials to sculpt their scat into cubelike nuggets, instead of the round pellets, messy piles or tubular coils made by other mammals, researchers reported November 18 at the American Physical Society Division of Fluid Dynamics meeting in Atlanta.

    Sound-absorbent wings and fur help some moths evade bats

    Some moths aren’t so easy for bats to detect.

    The cabbage tree emperor moth has wings with tiny scales that absorb sound waves sent out by bats searching for food. That absorption reduces the echoes that bounce back to bats, allowing Bunaea alcinoe to avoid being so noticeable to the nocturnal predators, researchers report online November 12 in the Proceedings of the National Academy of...

    Climate change may have made the Arctic deadlier for baby shorebirds

    Climate change may be flipping good Arctic neighborhoods into killing fields for baby birds.

    Every year, shorebirds migrate thousands of kilometers from their southern winter refuges to reach Arctic breeding grounds. But what was once a safer region for birds that nest on the ground now has higher risks from predators than nesting in the tropics, says Vojtěch Kubelka, an evolutionary...

  • 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...

    How roaches fight off wasps that turn their victims into zombies

    Real-life fights against zombie-makers offer plenty of tips for avoiding undeath. Just ask cockroaches, targets of the emerald jewel wasp.

    The female wasps (Ampulex compressa) specialize in attacking the American cockroach (Periplaneta americana). If a wasp succeeds, she leads away an unprotesting roach like a dog on a leash just by tugging at a roach antenna. Then she lays an egg on the...

    How researchers flinging salmon inadvertently spurred tree growth

    How much salmon would scientists sling if scientists could sling salmon? For one research team, the question isn’t hypothetical, and the answer is … tons.

    During 20 years of monitoring salmon populations in one southwest Alaskan stream, ecologists have found and flung a total 267,620 kilograms of dead fish into the forest. Those rotting carcasses leached enough nutrients to speed up tree...

    If you want to believe your home’s bug free, don’t read this book

    Never Home AloneRob DunnBasic Books, $28

    As I write this in my basement office, a sticky trap lies beneath my desk catching whatever insects wander by. Its current haul is pretty typical: a cricket, a spider and some small flies. But as Rob Dunn writes in his intriguing new book, Never Home Alone, I’m missing a lot if I think that’s all that lurks beneath my slippers.
