Kiyomizu-dera temple in Kyoto is famous for its 12-meter high Butai ('stage'). In Edo era, there was a popular superstition that if one survived a jump from the Butai, one's wish would come true. In this drawing, one woman holding an umbrella as a parachute has jumped from the Butai over the fully blossomed cherry trees. In the Drosophila wing imaginal discs drawn on her kimono, the spatial expression patterns of genes involved in pattern formation can be discerned. May the Drosophila wing imaginal discs differentiate into wings before she crashes to the ground. Drosophila adults have gathered from nowhere as if they escorted her in a cherry blossom snowstorm.
Spring, that is the season of arousal for many living creatures. Even among mammals, some squirrels, bears and bats hibernate. This woman is researching hibernation of an individual of the Siberian chipmunk. The body temperature of hibernating chipmunk firstly drops to near ambient temperature, and reciprocally repeats the state of less than 10 °C (sustained hibernation) and the state of almost 37 °C (inter-bout arousal) like the chart on this drawing. We hope that life science will shed light on the mechanisms of various environmental adaptations of life. We thank Dr. Yoshifumi Yamaguchi (Graduate School of Pharmaceutical Sciences, The University of Tokyo) for his valuable suggestions for our drawing.
