    Long-tongued fly sips from afar

    The “tongues” of South Africa’s long-tongued flies are certainly long, but they’re not flexible. So a fly has to hover at a distance to sip from a flower’s shallow nectar cup, as seen in the above photograph, which was honored in the 2015 BMC Ecology Image Competition....

    What fairy circles teach us about science

    A 2,000-kilometer strip of desert stretching across Namibia is pockmarked with mysterious “fairy circles.” From Angola to South Africa, millions of these bare patches of dirt (which can be seen on Google Earth if you know where to look) dot the...

    On the importance of elephant poop

    In the last century or so, Asian elephants have lost some 95 percent of their habitat and 90 percent of their population, and there are now fewer than 50,000 Elphas maximus elephants. One consequence of the loss is that some plant species are losing a key seed disperser. Elephants eat the plant’s fruit and defecate the seeds,...

    Defense hormones guide plant roots’ mix of microbes

    Plants help tend their own gardens. Salicylic acid, a plant hormone used to fight bacterial infections in leaves, also helps plants select which bacteria colonize their roots, researchers report online July 16 in Science.

    The finding provides an unexpected piece to an unsolved puzzle in plant biology: why...

    Missing enzyme to blame for scentless roses

    Stopping to smell the roses might be a letdown — and now researchers know why.

    The sweet-smelling flowers craft their scent using a surprising enzyme, previously thought to help prune genetic errors, researchers report July 3 in Science. That enzyme — and potent aroma — is missing in many roses bred for...

    New app creates a searchable network of species worldwide

    Part interactive field guide, part map, a new app compiles millions of records on species ranges worldwide. By pinpointing your location, the Map of Life app lets you explore plants and critters you might see nearby. Or tap around the globe to see what might be blooming in Singapore, for example. Click on a species name to reveal its range map (one...

    Poppy yields the final secret to making morphine

    The final puzzle piece in the chemical pathway that makes morphine has been identified, scientists report June 25 in Science. The work fills in the center piece in the path — the protein converting the compound (S)-reticuline to (R)-reticuline.

    By analyzing poppy DNA and confirming its function in yeast,...

    Beauty drives orchids towards extinction

    At plant markets in Thailand, exquisite orchids are for sale. Those orchids are unlike the ones you can buy at many U.S. shops; many of them are rare species that were collected from the wild. Selling them is illegal.

    This trade is “invisible” because hardly any of it makes it into government statistics that are supposed to document illegal trade in wild flora, Jacob Phelps and Edward...

    Could the dinos of ‘Jurassic World’ become invasive?

    Last weekend I watched Jurassic Park for the first time in years. Still awed by the seemingly realistic, long-extinct animals, I started wondering: What would happen if they escaped the remote Pacific island where they had been created and made it to land? The only dino in the movie series to make it to a continent was a ...
