曾经被认为在地下安全封存数千年的古老碳源正在意外地重新现身。一项涵盖广泛的国际研究发现，河流释放的碳气体中超过半数来自深层土壤和风化岩石等长期存在的古老碳源，而不仅仅是近期有机物。这一惊人发现表明，地球植被在吸收过剩碳以维持气候平衡方面正发挥着更为重要的作用。

宾夕法尼亚州立大学研究人员向硅材料在电子领域长期主导地位发起大胆挑战，成功构建出全球首个完全由原子厚度二维材料制成的可运行CMOS计算机。他们采用二硫化钼和二硒化钨制造了超过2,000个晶体管，能在无需传统硅材料的情况下执行计算机逻辑运算。尽管仍处早期阶段，这项突破预示着电子设备将迎来由单原子厚度材料驱动的革命性未来——设备更纤薄、运算更迅捷、能耗显著降低。

长期以来被认为在地下安全封存数千年的古老碳正大量重返地表。一项大规模国际研究发现，河流释放的碳气体中超过半数来源于深层土壤和风化岩石等长期存在的古老碳源，而非近期形成的有机物。这一惊人发现表明，地球植被通过吸收过量碳来维持气候稳定的作用比预想的更为重要。

一项广泛的国际研究发现，河流释放的碳气体中有超过半数源自深层土壤和风化岩石等长期存在的古老碳源，而不仅限于近期有机物。这项惊人发现表明，地球植被通过吸收过剩碳来调节气候的作用远超预期——本应在地下安全封存数千年的远古碳正在实际重新浮出地表。
