Our "Dr. Léopold Week” this year has come to an end! We deeply thank Pierre @leopoldlab.bsky.social for visiting us again. We also thank Prof. Chih-Chiang Chan and his team from National Taiwan University for visiting us as part of our collaboration! We had a wonderful party yesterday.

As has become an annual tradition over the past few years, I am delighted that Dr. Pierre Leopold @leopoldlab.bsky.social from the Institut Curie, Paris, visited us again in Tsukuba and, as usual, gave a lecture on developmental biology to undergraduate students.

Here is a news post about our work from our university: Even Boneless Insects Have an Endocrine System for Calcium Control https://www.tsukuba.ac.jp/en/research-news/20251023000000.html

Excited to share our paper, led by Naoki Okamoto in our group, just out in Nature! Neuroendocrine control of calcium mobilization in the fruit fly https://www.nature.com/articles/s41586-025-09670-z We “re”-discovered the calcium storage site in “boneless” Drosophila and revealed how calcium mobilization is regulated.

A new paper from our group: Stress-induced organismal death is genetically regulated by the mTOR–Zeste–Phae1 axis | PNAS https://pnas.org/doi/10.1073/pnas.2427014122 At least in Drosophila, organismal death caused by excessive stress is not possible without the involvement of a genetic pathway.
