中国科学技术大学合肥微尺度物质科学国家研究中心陈旸、赵东锋团队与地球和空间科学学院王宝善、姚华建团队合作，成功研制出具有自主知识产权的分布式光纤声波/振动传感（DAS）系统，该设备使用现有通讯光缆可进行地震监测、地质灾害预测、地下结构成像、城市地下空间探测等。
NG：水库在全球碳循环中为碳源而非碳汇（图）
碳循环 碳源 水利设施
2021/8/6
2009年的哥本哈根气候会议之后, 减排温室气体成为全世界最热门的话题，大量学者展开了对碳循环的研究工作。在碳循环中，有两个重要概念，碳源和碳汇。根据政府间气候专门委员会（IPCC）的有关定义，碳源是向空气中释放二氧化碳等温室气体的场所，碳汇是指从空气中吸收二氧化碳等温室气体的系统或区域。
Lunar samples solve mystery of the moon's supposed magnetic shield

2021/8/5
以中国科学院院士赵国春为学科带头人的西北大学地质学系超大陆学科团队员姚金龙教授等人与澳大利亚莫纳什大学Peter Cawood教授团队开展合作，所取得的最新成果可以从板块构造演化的角度为解答地球为什么能够演化成适宜人类居住的星球，又是什么在推动地球环境持续改善、推动生命出现与不断进化的一些疑惑。
Galaxies eventually undergo a phase in which they lose most of their gas, which results in a change into their properties over the course of their evolution. Current models for galaxy evolution sugges...
Scientists expose the cold heart of landfalling hurricanes

2021/8/6
Sand and mud subducted off the coast of California around 75 million years ago returned to the Earth's crust by rising up through the mantle as enormous diapirs, like blobs in a lava lamp, new researc...
平流层弱极涡北半球寒潮倾向变强（图）
北半球寒潮 平流层 极涡减弱
2021/8/4
兰州大学大气科学学院教授田文寿团队及国外合作者在《地球与环境通讯》发表题为《平流层弱极涡条件下北半球寒潮事件倾向于变得更强》的论文。指出，在北极平流层极涡减弱条件下北半球多数地区的寒潮可能更加严重，如东亚中纬度地区严重型寒潮的发生概率会增加100%，而适度型寒潮发生概率则增加40% 。
