Congratulations to the lucky winners who used slime mold to determine railroad track placement. I actually thought this was pretty neat research. Here is an article about their work.
Here is the announcement from the Improbable Research site:
TRANSPORTATION PLANNING PRIZE: Toshiyuki Nakagaki, Atsushi Tero, Seiji Takagi, Tetsu Saigusa, Kentaro Ito, Kenji Yumiki, Ryo Kobayashi of Japan, and Dan Bebber, Mark Fricker of the UK, for using slime mold to determine the optimal routes for railroad tracks.
REFERENCE: "Rules for Biologically Inspired Adaptive Network Design," Atsushi Tero, Seiji Takagi, Tetsu Saigusa, Kentaro Ito, Dan P. Bebber, Mark D. Fricker, Kenji Yumiki, Ryo Kobayashi, Toshiyuki Nakagaki, Science, Vol. 327. no. 5964, January 22, 2010, pp. 439-42.
[NOTE: THE FOLLOWING ARE CO-WINNERS BOTH THIS YEAR AND IN 2008 when they were awarded an Ig Nobel Prize for demonstrating that slime molds can solve puzzles: Toshiyuki Nakagaki, Ryo Kobayashi, Atsushi Tero]
WHO ATTENDED THE CEREMONY: Toshiyuki Nakagaki, Kentaro Ito, Atsushi Tero, Mark Fricker, Dan Bebber
