Nature：冥古宙时期含水的不均一地幔与宜居地球的形成（图）
冥古宙时期 不均一地幔 宜居地球 含水
2023/1/14
地球是已知唯一存在生命的星球，在地球形成最初的5亿年，地球环境可能经历了从炼狱到摇篮的剧烈转变。对于大气圈的演化而言，地球早期的大气由浓厚的CO2等温室气体组成，不利于生命的存在。而到了冥古宙末期，大气中CO2分压就已经极低。CO2是温室气体的主要成分，可以以深海碳酸盐矿物的形式进入地幔被封存在地球内部。但是冥古宙时期，究竟是何种过程导致了如此巨量的CO2被封存在地幔深部？早期地球又如何演化成为生...
浙江大学生命科学研究院2022年6月9日方东实验室在Nature Communications杂志发文揭示SMYD5在基因启动子区域催化组蛋白H3K36三甲基化（图）
基因启动 催化组蛋白H3K36 三甲基化
2022/10/25
组蛋白修饰作为表观遗传信息的主要载体之一，具有调节细胞内基因表达的功能。其中研究较多的H3K36位点甲基化通常被认为是富集于基因间区和基因区的活性标记，其功能包括参与细胞活动，DNA损伤，转录起始，RNA剪切，RNA m6A修饰等。
Nature: 黄石公园地热系统流体通道的地球物理成像（图）
黄石公园 地热系统 流体通道 地球物理成像
2023/1/14
美国西北部的黄石国家公园因其独特、丰富的地热景观而闻名于世。公园内包含了间歇泉、喷气孔、泥火山、沸泉和热液爆炸遗迹等1000多处地表地热景观。自19世纪70年代以来，黄石公园独特的热液系统吸引了众多研究人员的目光。深部的岩浆系统的热量通过活动断裂带上涌，构成地热系统的热源，同时断裂带还构成了流体循环的通道，使低温流体循环到深部高温地区，并以高温流体的形式回流到地表（Fournier, 1989；G...
