Comet 官方于 9 月 23 日举办线上研讨会，演示即将发布的 Dragonfly 3D World 2027 的新功能，包括基于 Meta SAM 的 AI 实例分割、Subvoxel Multi-Mesh 亚体素多重网格、Fast Split 快速实例分离、Report Builder 报告生成器等。官网 Events 页面还公布了后续活动：9 月 28 日 France Volume-EM Scientific Days（Bordeaux）、10 月 4 日 MS&T 2026（Pittsburgh）、10 月 12 日 ASNT 2026（Columbus）。Comet hosted an online webinar on September 23 introducing Dragonfly 3D World 2027: SAM-based AI instance segmentation, Subvoxel Multi-Mesh, Fast Split, Report Builder and more. The Events page also lists upcoming appearances — France Volume-EM Scientific Days on Sep 28 (Bordeaux), MS&T 2026 on Oct 4 (Pittsburgh), and ASNT 2026 on Oct 12 (Columbus).

研究团队在纳斯卡海脊（670 米深）发现泡泡糖珊瑚新物种 Paragorgia quitinosa，并首次在八放珊瑚组织中确认甲壳素（chitin）是无轴骨骼群体的结构支架。团队把 micro-XCT 扫描的珊瑚碎片（Zeiss Xradia 620 Versa，5.05 μm 体素）导入 Dragonfly 3D World，对 10 个随机选取的虹吸水螅体 ROI 沿 z 轴手动勾画并插值分割卵母细胞，进而计算每个 ROI 的 Feret 直径。A new bubblegum coral species, Paragorgia quitinosa, collected at 670 m depth on the Nazca Ridge, provides the first analytical evidence of chitin as a structural scaffold in octocoral tissues. The team segmented oocytes in Dragonfly 3D World from micro-XCT scans (Zeiss Xradia 620 Versa, 5.05 μm voxels) by manually outlining and interpolating ROIs along z in 10 haphazardly selected siphonozoids, then calculated Feret diameters for each ROI.
