夫婦岩に現れた腸ジオメトリーの性差
The first sunlight of 2025 illuminates the Meoto-iwa (a pair of rocks resembling a married couple). The shapes of these rocks are somewhat unique, resembling the gut morphology of the male (left) and female (right) adult Drosophila. Blackie et al. used micro-CT (computed tomography) to scan numerous adult Drosophila and revealed detailed sex differences in the geometry of organ spatial arrangements, including the gut (Blackie et al. (2024) Nature 630: 392-400, DOI: 10.1038/s41586-024-07463-4).
2025年最初の日の光が夫婦岩（夫婦のように並ぶペアの岩）を照らす。これらの岩の形は少し変わっており、ショウジョウバエ成虫のオス（左）とメス（右）の腸管のような形状をしている。BlackieらはマイクロCT（コンピュータ断層撮影）を用いて多数のショウジョウバエ成虫をスキャンし、腸管をはじめとする臓器配置のジオメトリーの性差の詳細を明らかにした（Blackie et al. (2024) Nature 630: 392-400, DOI: 10.1038/s41586-024-07463-4）。

ニューロンもみじ真っ盛りの全脳マップ島
This depicts a seashore in late autumn, where maple leaves resembling neurons are tinged with autumn red. In the distance, you can see an island, which is a whole brain map of Drosophila (Dorkenwald et al. (2024) Nature 634: 124-138, DOI: 10.1038/s41586-024-07558-y), entirely composed of neuron-like maple leaves. Fly whole brain map: Adapted from Figure 1(a) of © Dorkenwald et al.

まるでニューロンのようなもみじが赤く色づいた晩秋の海辺の景色。向こうに見えるのは、全体がニューロンもみじからなるショウジョウバエの全脳マップ（Dorkenwald et al. (2024) Nature 634: 124-138, DOI: 10.1038/s41586-024-07558-y）の島である。Fly brain map: Adapted from Figure 1(a) of © Dorkenwald et al. (2024) Nature 634: 124-138, DOI: 10.1038/s41586-024-07558-y.
