The change to agar was a marked improvement. The jelly is so effective that it is still an invariable ingredient in what is known today as the “Koch’s plating technique” or the “culture plating method.” As Koch himself noted in 1909: “These new methods proved so helpful…that one could regard them as the keys for the further investigation of microorganisms…Discoveries fell into our laps like ripe fruits.”

In just a few weeks, the four astronauts will be strapped into a spacecraft, perched on the top of the rocket, ready to blast off to the Moon.
彼时,新兴技术正从边缘切入,重构存储生态。比如MRAM(磁阻存储器)兼具SRAM速度、DRAM密度与Flash非易失性,已在车规级MCU、工业控制器中商用,三星、台积电、英特尔等均在持续推进该技术进展。ReRAM(阻变存储器)单元面积小,读写速度是NAND的1000倍,同时功耗可以降低15倍。CXL(Compute Express Link)虽非存储介质,却是内存池化的关键。通过CXL,服务器可将多个DRAM/HBM模块虚拟为统一内存池,大幅提升AI训练效率。Intel、AMD、三星正推动其成为下一代数据中心标配。不过,新兴存储并非要“取代”DRAM或NAND,而是填补其无法覆盖的“价值缝隙”。未来将是“传统+新兴”的分层共存格局。
