蚊子口器启发 3D 打印喷嘴设计
加拿大麦吉尔大学与美国德雷塞尔大学团队联合开发出一种颇具创意的高分辨率3D打印新技术。他们将雌性蚊子的口器(吸血管)转化成了高分辨率的3D打印喷嘴。这种技术不仅能打印出精度达 20 微米的极细线条,还为解决昂贵、高能耗的微纳制造难题提供了可持续的生物学方案。高分辨率 3D 打印对喷嘴精度要求极高。目前市售的超细喷嘴多由特种金属或玻璃制成,制造工艺复杂,成本高昂。研究团队指出,传统喷嘴在生产和使用过程中不仅产生大量环境废弃物,还可能因工艺局限带来健康风险。为了寻找替代方案,研究团队将目光投向自然界中高度进化的微结构——蚊子口器。经过数百万年进化,蚊子口器形成了一种直径仅为人类发丝直径一半左右的天然微针结构,兼具特殊几何形态和力学韧性。研究团队在显微镜下分离出蚊子吸血管,并利用特种树脂将其固定在标准塑料分配器尖端。结果发现,这种生物喷嘴能承受极大的压力,打印出的复杂结构精细程度大约是目前商业打印喷嘴的 2 倍。 via Solidot

KDE Plasma 的 2025 年
KDE 开发者总结了桌面环境 Plasma 在 2025 年的重要进展:切换到 Wayland 显示服务器的工作基本完成,2027 年初发布的 Plasma 将停止支持 X11 会话;Plasma 持续改进和成熟,成为众多面向游戏发行版的默认桌面环境,这些发行版包括了 Bazzite、CachyOS、Garuda、Nobara,以及 Valve 掌机/主机运行的 SteamOS。Fedora 发行版也将其 Plasma 桌面版本与 GNOME 桌面版本放在同等位置,唯一能在苹果新 Mac 设备上运行的发行版 Asahi Linux 使用的也是 KDE Plasma 桌面。Parrot Linux 最近也开始默认使用 Plasma。EndeavourOS、Manjaro、NixOS、OpenMandriva、Slackware 和 TuxedoOS 等老牌发行版的默认桌面环境都是 Plasma。 via Solidot

俄罗斯入侵乌克兰改变了乌克兰人的成人内容消费习惯
根据发表在《Archives of Sexual Behavior》期刊上的一项研究,俄罗斯入侵乌克兰改变了乌克兰人的成人内容消费习惯。调查显示,2022 年 3 月初乌克兰人的网络行为发生显著改变。这一时间段与俄罗斯入侵的时间点高度吻合,俄罗斯入侵始于 2 月 24 日。数据显示,期间乌克兰民众对色情内容的搜索量显著增加,对战争地图和保持社交距离信息的搜索量也大幅上升。战争严重程度与成人网站访问量之间存在显著的统计相关性。日益加剧的孤立感和危险感似乎推动了对色情内容兴趣的增长。研究人员称,在集体威胁和社会动荡的紧张时期,人们可能会转向独处的性行为如观看色情作为一种应对或自我调节的策略。 via Solidot
