Communications & Public Relations Committee

The University of Tokyo's Graduate School of Science and Faculty of Science held the "The University of Tokyo School of Science Image Contest 2023" from May 26 to July 25, 2023, to capture a moment of daily research and educational activities and compete in their beauty.
The image contest had been held as part of the Open Campus, but this year it was held independently again because the Open Campus was held online.

This year we received 30 entries from science students, faculty, and campus staff.
Voting was conducted by the constituent members of the Faculty of Science Communications & Public Relations Committee, and the top three entries receiving the most votes were selected for the Excellence Awards.
The Excellence Award winners will receive a certificate of commendation and a book token as a prize.

Some of the entries, including the Excellence Award winners, will be published in the Image Bank of the Faculty of Science of the University of Tokyo.

The image contest will be held again next year and beyond.

Grand Prize

The warm heart of worms" by Shinichi Miyazaki, Assistant Professor, Sleep Physiology Laboratory, Department of Biological Sciences

"Picking up Fallen Stones" by Satoshi Yoshihara, 1st year Master's student, Department of Earth and Planetary Science
This is a photograph taken during a field trip to Sicily by the Department of Earth and Planetary Environmental Science. The composition of the plaster being collected with the cloudless blue sky and sea of the Mediterranean Sea at the side overlaps with Millet's "Picking Up Fallen Gems," and I felt that the photograph is typical of the Department of Environmental Studies, which continues to face earth science wherever it goes.

"Delivering to the Honey" by Ryosuke Motoyoshi, 4th year Faculty, Department of Biology
A bee, lured by the vivid color of the flowers of the crenate, flies to the flower and thrusts its proboscis to suck the nectar hidden behind the long flower tube. At this point, the bee's face comes into contact with the tip of the stamen, and the pollen is transferred to and from the flower. This photo captures the climax of the pollination symbiosis.

Shingo Hirano, Project Researcher, Department of Astronomy
When I was conducting a simulation of the evolution of the universe, I made a mistake and advanced the simulation to the future. The universe is currently bustling with countless galaxies, but it seems that its old age will be a quiet one.
