    A mussel poop diet could fuel invasive carp’s spread across Lake Michigan

    If invasive carp reach Lake Michigan, a buffet of mussel poop and other junk food could help the fish survive and spread.

    Once thought to be a food desert for these fish, the lake may provide enough nutrition for two Asian carp species, bighead (Hypophthalmichthys nobilis) and silver carp  (H. molitrix), thanks to their not-so-picky eating habits, researchers report August 12 in...

    Plants don’t have feelings and aren’t conscious, a biologist argues

    Lincoln Taiz is peeved. Over the last decade or so, the retired plant biologist has watched the rise of the field of “plant neurobiology” with growing dismay.

    That controversial field, which debuted in a 2006 article in Trends in Plant Science, is based on the idea that plants — which do not possess brains — nonetheless handle information in ways that resemble sophisticated animal...

    A deadly fungus gives ‘zombie’ ants a case of lockjaw

    Fungus-infected “zombie” ants are known to scale a plant, sink their jaws into a leaf or twig and wait to die while the Ophiocordyceps unilateralis fungi feast on the insects’ bodies. Eventually, a fungal stalk shoots out of the ant’s head and releases spores that rain down and infect more ants below.

    The carpenter ants’ part in this nightmare may seem dictated by mind control, but the...

    Planting trees could buy more time to fight climate change than thought

    A whopping new estimate of the power of planting trees could rearrange to-do lists for fighting climate change. 

    Planting trees on 0.9 billion hectares of land could trap about two-thirds the amount of carbon released by human activities since the start of the Industrial Revolution, a new study finds. The planet has that much tree-friendly land available for use. Without knocking down...

    Moonlight shapes how some animals move, grow and even sing

    Crowds of people gather to watch an evening spectacle on beaches in Southern California: Twice a month, typically from March through August, the sand becomes carpeted with hundreds or thousands of California grunion. Writhing, flopping, silvery sardine look-alikes lunge as far onto shore as possible. As the female fish dig their tails into the sand and release eggs, males wrap around females...

    Here’s the science behind some of your favorite things to do in summer

    Summer brings the heat — and in some cases a lot of it, as those who suffered through record-breaking heat waves in Europe and South Asia in June can attest. But the season also ushers in long days filled with plenty of possibilities for outdoor fun. Parks fill with picnickers. Mountain trails fill with hikers. And beaches and pools swarm with swimmers trying to beat the heat.

    Here’s...

    Why some insect eggs are spherical while others look like hot dogs

    Look at the nail of your pinky finger. That’s about the width of the biggest known insect egg, which belongs to the earth-borer beetle Bolboleaus hiaticollis. The smallest egg, from the wasp Platygaster vernalis, is only half the width of the thinnest recorded human hair.

    Insect eggs range across eight orders of magnitude in size, and come in a stunning variety of shapes, a new database...

    Parasites ruin some finches’ songs by chewing through the birds’ beaks

    Invasive parasites in the Galápagos Islands may leave some Darwin’s tree finches singing the blues.

    The nonnative Philornis downsi fly infests the birds’ nests and lays its eggs there. Fly larvae feast on the chicks’ blood and tissue, producing festering wounds and killing over half of the baby birds. Among survivors, larval damage to the birds’ beaks may mess with the birds’ songs when...

    The world’s fisheries are incredibly intertwined, thanks to baby fish

    Marine fisheries are typically managed by individual nations. But the fish in those stocks often originate elsewhere, according to a computer simulation of how eggs and larvae from hundreds of fish species ride ocean currents around the world.

    That finding means that many nations with economies that rely on fishing must depend on other countries to maintain important spawning grounds....

    Hyenas roamed the Arctic during the last ice age

    Modern hyenas stalk the savannas of Asia and Africa, but the animals’ ancient relatives may have had snowier stomping grounds: the Arctic. Two fossilized teeth, collected in Canada in the 1970s, confirm a long-held hunch that ancient hyenas ventured into North America via the Bering land bridge, scientists say.

    The teeth belonged to members of the extinct genus Chasmaporthetes, also...
