    A caterpillar outwits corn defenses by gorging on fattening ‘junk’ food

    Here’s the story of a caterpillar that foils gruesome violence orchestrated by corn.

    No, that’s not backward. Plants often look helpless to a human, but they fight with smells and other invisible chemistry. A growing body of evidence, for example, shows that plants under attack can waft out scents that attract help, such as tiny wasps that deal a lingering death to leaf-chewing...

    Keeping global warming to 1.5 degrees C helps most species hold their ground

    Limiting global warming this century to just 1.5 degrees Celsius above preindustrial temperatures would be a boon to the planet’s biodiversity. This lower warming threshold, compared with warming of 2 degrees C, will preserve much larger swaths of the geographic ranges of tens of thousands of land-based species of plants, vertebrates and insects living on the planet, a new study suggests.

    See (and hear) the stunning diversity of bowhead whales’ songs

    In the pitch-black waters beneath the Arctic ice, bowhead whales get funky. A small population of endangered bowheads belt an unusually varied repertoire of songs, which grows more diverse during mating season.

    Hunted to near extinction in the 1600s, these fire truck–sized mammals now number in the 300s in the frigid waters around the Svalbard archipelago in Norway. Underwater audio...

    Masses of shrimp and krill may play a huge role in mixing oceans

    When it comes to tiny ocean swimmers, the whole is much greater than the sum of its parts. Ocean turbulence stirred up by multitudes of creatures such as krill can be powerful enough to extend hundreds of meters down into the deep, a new study suggests.

    Brine shrimp moving vertically in two different laboratory tanks created small eddies that aggregated into a jet roughly the size of the...

    Flying insects tell tales of long-distance migrations

    Every autumn, a quiet mountain pass in the Swiss Alps turns into an insect superhighway. For a couple of months, the air thickens as millions of migrating flies, moths and butterflies make their way through a narrow opening in the mountains. For Myles Menz, it’s a front-row seat to one of the greatest movements in the animal kingdom.

    Menz, an ecologist at the University of Bern in...

    Some frogs may be bouncing back after killer chytrid fungus

    It’s tough to be a frog once a killer skin fungus moves in. But, in Panama, the amphibians might be fighting back, researchers propose.

    More than a decade ago, an amphibian-killing chytrid fungus nicknamed Bd swept through the country. Now some frog species that had nearly vanished from three regions are growing easier to spot again. But tests of the pathogen find no signs that it is...

  • 50 years ago, invasive species traveled the Suez Canal

    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

    This scratchy hiss is the closest thing yet to caterpillar vocalization

    Tap — gently — the plump rear of a young Nessus sphinx hawk moth, and you may hear the closest sound yet discovered to a caterpillar voice.

    Caterpillars don’t breathe through their mouths. Yet a Nessus sphinx hawk moth, if disturbed, will emit from its open mouth a sustained hiss followed by a string of scratchy burplike sounds. “Hard to describe,” says animal behaviorist Jayne Yack of...

    Ants practice combat triage and nurse their injured

    View the video

    No wounded left behind — not quite. Ants that have evolved battlefield medevac carry only the moderately wounded home to the nest. There, those lucky injured fighters get fast and effective wound care.

    Insect colonies seething with workers may seem unlikely to stage elaborate rescues of individual fighters. Yet for Matabele ants (Megaponera analis) in sub-Saharan...

    It’s a bad idea for a toad to swallow a bombardier beetle

    View the video

    Toad versus bombardier beetle is almost a fair fight. Toads are hugely bigger, can tongue-strike in an eyeblink and swallow all kinds of nasty stuff. But bombardier beetles can shoot hot steam and noxious chemicals from their back ends.

    In a lab face-off, 43 percent of Pheropsophus jessoensis bombardiers escaped alive after being swallowed by toads, a pair of...
