… or at least it’s good for the health of mice, maybe.

A group that includes Teikyo University associate professor Masanori Niimi was honored with the Ig Nobel Prize for medicine for research involving heart transplants on mice and three types of music, including opera and classical.

According to a report by the group published in the Journal of Cardiothoracic Surgery in March 2012, mice that had undergone heart transplants were exposed to the opera “La Traviata,” classical music by Mozart, songs by Irish pop singer Enya and simple sound frequencies.

Such mice normally live an average of seven days, but those treated to the opera survived 26.5 days and those that listened to Mozart held on for 20 days. The mice that listened to Enya or simple sound frequencies, however, lived only seven to 11 days.

“Our findings indicate that exposure to opera music, such as ‘La Traviata,’ can affect such aspects of the peripheral immune response,” the group said in its report.


And okay, these ARE the Ig Noble prizes! 😉


  1. OK, you got me! I believed it up until I read the bottom line below RTWT…

    But I *was* wondering if mice who hadn’t heard any music lived longer or shorter than the music ones.

  2. Hey, it had me too …
