Following a magnitude 7.4 powerful earthquake that struck Colombia on Monday local time and left hundreds dead and injured, the Chinese Embassy in Colombia said early Tuesday that it has yet to receive reports of casualties among Chinese nationals.
In a post published on its official WeChat public account, the Chinese Embassy in Colombia said it attaches great importance to the safety of Chinese nationals in Colombia and activated its emergency response mechanism immediately to conduct a comprehensive check on the impact of the disaster on Chinese nationals.
So far, no information about Chinese casualties has been received, the embassy said.
According to the Colombian Geological Service, the quake struck at 7:34 am local time in western Colombia. Its epicenter was near San Jose del Palmar, in the department of Choco, at a depth of 96 km, the Xinhua News Agency reported.
The death toll from the earthquake has risen to 111 nationwide, with 87 others injured, Colombian President Abelardo de la Espriella said in Bogota, per Xinhua.
The Chinese Embassy in Colombia also reminded Chinese nationals in Colombia to stay highly vigilant against secondary earthquake hazards including aftershocks and public health risks.
It also advised those encountering emergencies to promptly contact local police and reach out to the embassy for assistance.
The Colombian government earlier Monday declared a state of national disaster to respond to the impact of the earthquake, Xinhua reported.
The quake comes less than two months after twin quakes devastated the north of Venezuela, killing more than 6,300 people, the BBC reported, adding that "it is one of its largest earthquakes in years."

。 人民网西安4月21日电(记者李志强)近日,记者从西北大学获悉,该校早期生命与环境研究团队与中国科学院地质与地球物理研究所、上海交通大学等单位科学家合作,在5.18亿年前的寒武纪清江生物群中发现多细胞结构的丝状硫酸盐还原细菌化石清江丝菌,并结合分子生物学分析结果,还原了硫酸盐还原菌与地球环境协同演化历史。 细菌化石是指保存在岩石中的细菌遗体或其活动留下的痕迹。据专家介绍,在此之前,除了少数有特殊形貌的蓝细菌化石和趋磁细菌磁小体化石外,在古老地质记录中还没有发现可靠的硫酸盐还原细菌化石。硫酸盐还原菌的演化与地球环境变化的关系,科学界也没有明确的认识。 清江丝菌化石的产地和环境背景。

三 | 这些细菌在环境科学、生态学和工业领域中都具有极为重要的意义。它们是地球硫循环的关键推动者,通过还原硫酸盐参与到硫的生物地球化学循环中,影响硫在不同价态和形态间的转化。同时,它们也参与有机质的分解和甲烷氧化等过程,从而调节海洋的氧化还原状态和温室气体排放。

四 | 研究团队根据化石证据和谱系基因组学分析结果,提出硫酸盐还原菌与地球氧化事件协同演化假说,认为脱硫细菌门首先在24亿年前的大氧化事件期间发生辐射演化,约8.5亿年前演化出丝状多细胞种类;在新元古代末期,地球第二次氧化事件导致海底广泛氧化,丝状种类约在5.6亿年前获得传导电子功能,硫酸盐还原通路逆转,演化成可以跨越氧化还原界面,一端在还原带氧化硫,另一端在氧化带还原氧的电缆细菌。清江丝菌化石的多细胞丝状体形态。

五 | 西北大学供图 据介绍,这项研究是古生物学、地球化学、谱系基因组学交叉合作的结果,同时借助了多种高分辨率、高精度显微和微区原位分析技术,是在多学科交叉背景下探究微生物硫酸盐还原作用与地球环境协同演化的首次尝试,对融合利用显微学和基因组学等最新技术、促进地学与生物学前沿交叉、探索解决地球与生命协同演化等具有重要意义。 同时,这项研究还能够为科学家探讨“生命在火星等其他行星上的存在、演化的可能性研究”提供参考,为人类寻找地外生命提供了一种可能的途径。
