    How koalas sing low

    Koalas have a newly discovered extra set of vocal cords that allows males to hit notes 20 times lower than expected.

    Because the sizes of an animal’s voice box and its flapping vocal cords dictate the range of pitches an animal can make, a typical 8-kilogram koala should stick near the soprano section. But the male’s sexy mating songs, which to humans sound like a string of belches and...

    Tree cricket song has note of variability

    Unique wings allow one type of male tree cricket to hum a different sort of tune — one that encompasses a wide range of pitches. The discovery could mean that these males are saying a lot more than previously thought, and that potential mates might be listening for these notes.

    “The frequencies might be carrying some information about the condition of the male.  An insect...

    Monster stingrays: Field notes from a global wrangler

    Tonight, couch potatoes with access to the National Geographic channel can watch a biologist pursue some of the biggest fish on Earth: giant stingrays. Since 2006, National Geo has been funding Zeb Hogan’s research on “megafish” — global treks to study freshwater behemoths that strain our vocabularies for appropriate superlatives. When the University of Nevada-Reno scientist was in Washington...

    Finch Concerts: Female bird brain notes male attention

    He knows she's listening. And now we know that she knows he knows.

    Using the word "know" loosely, that's a simplified version of a new analysis of zebra finches by neuroscientists at the University of California, San Francisco.

    Sarah Woolley explains that males sing a song differently when they're in front of females than when they're just twittering to themselves. Now...

    Sharp rise noted in meds for youths

    Antipsychotic-drug treatment of children and teenagers seen by office-based physicians increased dramatically between 1993 and 2002, according to a national study.

    Potent Medicine

    The test for the boys and girls was simple: to cover as much ground as they could in 6 minutes. But these children, ages 5 to 18, had pulmonary hypertension—high blood pressure in their lungs from constricted blood vessels. Such kids "don't have a lot of energy," explains pediatric cardiologist Tilman Humpl. "They can't exercise at all. They may not be able to walk up from the basement to the...

    Dee for Danger: Chickadees add notes as threat grows

    Biologists report new progress in translating the sophisticated communication system of black-capped chickadees.

    When the little birds spot a lurking predator, they burst out with variations on their "chickadee" calls. Tests with 15 predator species show that birds vary those calls depending on how dangerous the predator is, says Christopher N. Templeton of the University of...

    A Low Note in Cosmos: Sounding out a new role for black holes

    It's a tone no one can hear, generated by a body no one can see, yet its reverberations may be huge. Astronomers reported this week that they have for the first time detected sound waves generated by a black hole.
