Apple is offering replacements for its first-generation iPod nano, which includes a battery that might overheat. Affected devices were sold between September 2005 and December 2006, Apple said in a note on its Web site. But according to Cupertino, the overheating has occurred only in “very rare cases.”
Other versions of the iPod are not affected. The first-generation devices have a black or white plastic front and a silver metal back.
The terrifyingly toothy anglerfish became a common occurrence in little kids’ nightmares ever since it chased Nemo and Dory in Pixar’s “Finding Nemo.” To attract prey, the scary-looking fish uses a bioluminescent “fishing pole” that hangs just above and in front of its toothy face. The lure is actually a piece of dorsal spine packed with millions of glow-in-the-dark bacteria.
Previous research on the subject suggested that the sound is acoustically similar to the warning call of a primate, but that theory was debunked after monkeys responded to amplitude-matched white noise and other high-pitched sounds, whereas humans did not. Another study, in 1986, manipulated a recording of blackboard scraping and found that the medium-pitched frequencies are the source of the adverse reaction, rather than the the higher pitches (as previously thought). The work won author Randolph Blake an Ig Nobel Prize in 2006.
The latest study, conducted by musicologists Michael Oehler of the Macromedia University for Media and Communication in Cologne, Germany, and Christoph Reuter of the University of Vienna, looked at other sounds that generate a similar reaction — including chalk on slate, styrofoam squeaks, a plate being scraped by a fork, and the ol’ fingernails on blackboard.
