NASA OSIRIS-REx 探测器于 2020 年 10 月登陆距地球 3.2 亿公里的小行星 Bennu，收集了 120 克尘埃与岩石样本，2023 年 9 月样本舱降落在犹他州沙漠。对样本的分析发现了盐类矿物如岩盐（halite）与钾石盐（sylvite），以及有机化合物与构成生命的物质，包括 14 种与地球生物过程相关的胺基酸，以及某些未在已知生物体中发现的胺基酸。根据发表在《Nature Geoscience》期刊上的最新研究，科学家首次在样本中发现生命所需的糖类，表明小行星可能曾将生命所需的所有先决条件输送到地球——甚至其他地方。日本东北大学的科学家在样本中发现了核糖，以及其他多种糖类，包括来苏糖、木糖、阿拉伯糖、葡萄糖和半乳糖，但未检测到脱氧核糖。这些糖类是在 Bennu 母体小行星所含的富甲醛卤水中形成的。科学家推测，Bennu 母体小行星曾含有更多液体，并发生过更丰富的化学反应。

三星是一个庞大无比的韩国财团，旗下有各种业务，如生产内存的三星半导体，制造手机的三星电子移动。当一家子公司需要零部件，它们优先考虑的供货对象肯定是同一家公司的其它子公司。但在 AI 时代，为子公司供应零部件获得的利润可能远不及 AI 公司或数据中心。据 SE Daily 报道，三星电子移动想要与三星半导体达成一年的移动内存芯片供应长约，但遭到了拒绝，双方最终只达成价格更昂贵的短约，需要每季度重新谈判价格。从目前的迹象看，内存价格飙升可能将会持续很长时间，消费者别指望 2026 年内存会降价了。
