This anomaly is indicative of the larger challenge of culturing various microbial species, referred to as microbial “unculturability.” This cannot be explained by the use of agar alone or by the substitution of an alternative gelling agent, but rather by the difficulties in consistently recreating on an agar plate the multi-variable environment in which microbes grow naturally. Given such challenges, the risk of shortages, and the vulnerabilities of the agar supply chain, why is it so difficult to find suitable alternatives?
OpenAI has closed another round of funding, totalling $110 billion being newly committed to the maker of ChatGPT, which it says has more than 900 million weekly active users and over 50 million consumer subscribers. Amazon is investing $50 billion and striking a deal that includes plans for custom models and more. Nvidia and SoftBank are each contributing $30 billion, as well, even as the Wall Street Journal notes that Nvidia's previous $100 billion investment plan is "on ice." This marks another massive influx of cash for the company that's now valued at $730 billion, and previously closed a $40 billion round in 2025. At the time, it was th …

在高端市场，AI产业化的加速落地直接引爆了存储需求。不同于传统服务器，AI服务器需要承载大规模数据训练、高频次数据运算，对HBM（高带宽存储）、高端DDR5内存及企业级SSD的需求量呈爆发式增长，单台AI服务器的存储需求量更是达到传统服务器的8-10倍。其中，HBM凭借超高带宽、低延迟的核心优势，成功破解了AI运算中的“内存墙”技术瓶颈，成为AI算力基建的核心战略级资源，目前2026年全球三大存储巨头的HBM产能已全部提前售罄，部分头部AI企业甚至提前签订2027年长期供货协议。
