    A Different Kind of Smart

    Zola the crow is about to face a test that has baffled animals from canaries to dogs.

    She’s a wild New Caledonian crow, and for the first time, she’s seeing a tidbit of meat dangling on a long string tied to a stick. She perches on the stick, bends down, grabs the string with her beak and pulls. But the string is too long. The meat still hangs out of...

    The Human Brainome Project

    Brain research has been on a lot of minds lately in the nation’s capital. After offering a brief shout-out to Alzheimer’s research in his February State of the Union address, President Barack Obama went a step further in April by announcing a decade-long effort to develop advanced tools for tracking human brain activity. The administration dubbed it the Brain Research through Advancing...

    Reports of junk DNA's 'demise' were based on junky logic and dubious definitions

    Science is an oddly successful enterprise. On the whole, it provides an impressive guide to reality. From antibiotics and atomic bombs to laser beams and X-rays, science enables humans to forge powerful tools from nature’s secrets.

    Yet many aspects of science are deeply flawed, from the politicization of research funding to widespread misuse of math in analyzing data.

    In this...

    Compared with rodents, bat species carry more viruses

    A bat species may be more likely than a rodent to carry viruses known to jump from other animals to people, a new study suggests.

    Per species, bats also harbor more known viruses in total than rodents do, including wildlife-only infections as well as those that also infect people, says Angela Luis of Colorado State University in Fort Collins. And a bat virus on average has a...

    Finally, the truth about barnacle sex is revealed

    Confounding more than a century of received wisdom about crustacean sex, genetic tests show that at least one kind of barnacle can transfer sperm without making direct contact via their famously extendable parts.

    The Pollicipes polymerus gooseneck barnacles along the coast of the northeast Pacific have sperm-delivery organs that stretch out about half a body length, which is...

    Pregnant male pipefish have hormone swings

    The first study to track a form of testosterone through male pregnancy in fish has found an unusual roller coaster of swoops and spikes.

    Among pipefishes, seahorses and sea dragons, females produce eggs but males get pregnant, carrying the embryos. Even though pregnant male Gulf pipefish (...

    Cell biologists hone elevator pitches

    A senator and a scientist walk into an elevator. If the scientist happens to be Navneeta Pathak or Kiani Gardner, science funding might also get a lift.

    Pathak and Gardner won a contest at the annual meeting of the American Society for Cell Biology that required competitors to describe their research in a one- or two-minute spiel that the general public could understand. The idea is to...

    News in brief: Fins to limbs with flip of genetic switch

    Evolving limbs from fins may be as easy as taking the activity of a few genes and kicking it up a notch, a new study suggests.

    Many evolutionary biologists have thought that four-limbed creatures evolved from finned ancestors. Forming limbs involves turning on body patterning genes in two precisely timed phases, first in the back legs and then, later, in the part of the limb...

    E. coli caught in the act of evolving

    Big leaps in evolution are the products of tiny genetic changes accumulated over thousands of generations, a new study shows.

    E. coli bacteria growing in a flask in a lab for nearly 25 years have learned to do something no E. coli has done since the Miocene epoch: eat a chemical called citrate in the presence of oxygen. Evolutionary biologists Zachary Blount and Richard Lenski...

    Heat Beaters

    In the middle of a cattle ranch near Gerlach, Nev., enclosed by a corrugated metal fence, are small pools of steaming water. Close to the surface of these pools, water temperatures reach about 90° Celsius; deeper down, it’s even hotter. Landowners have sectioned off the area around the pools and installed an overflow pipe to keep the water from seeping out and harming livestock or people....
