据8月27日《自然》杂志报道，英国伦敦大学学院（UCL）化学家通过模拟早期地球的条件，首次实现 了RNA与氨基酸的化学连接。这一难题自20世纪70年代以来一直困扰着科学家，如今，这一突破性成 果为解答生命起源中"蛋白质如何合成"的关键问题提供了新思路。 氨基酸是蛋白质的构建单元，而蛋白质是生命的"主力军"，几乎参与所有生物过程。然而，蛋白质无法 自我复制或合成，它们需要"说明书"，而这一说明书由RNA提供。RNA是DNA（脱氧核糖核酸）的近 亲，负责传递遗传信息，控制蛋白质合成。 在现代生物体内，核糖体负责合成蛋白质。它读取信使RNA（mRNA）上的遗传密码，将氨基酸依次拼 接成蛋白质。核糖体就像一条流水线，逐个读取RNA上的指令，并将氨基酸依次拼接，形成蛋白质。 此次，研究团队完成了这一复杂过程的第一步。他们在中性水溶液环境下，通过化学反应将氨基酸与 RNA连接。研究表明，该反应具有自发性和选择性，并可能在40亿年前的原始地球池塘或湖泊中发 生。 过去，此类实验往往依赖高反应性分子，但它们在水中不稳定，导致氨基酸彼此结合而非与RNA结 合。现在，团队借鉴生物学机制，引入了硫酯作为活化中间体。硫酯是一类高能化 ...

太阳风注入的氢（H）是月表水的重要来源。以往对嫦娥五号月壤中橄榄石、辉石等硅酸盐矿物的分析 发现，这些矿物表层水含量很高，且主要来自太阳风。但近期有遥感观测显示，月表水的分布似乎与钛 的含量有关：低钛区域含水量通常高于高钛月海玄武岩区域，且富钛区域水的日变化更明显。这一现象 在科学界引发了不小的争议。 "为了厘清这一问题，我们对嫦娥五号月壤中挑选出的11颗钛铁矿颗粒展开精细分析。结果显示，这些 颗粒表层确实含有水，其氢同位素特征表明它们的确来自太阳风。"论文第一作者、中国科学院国家空 间科学中心副研究员徐于晨告诉记者，但与硅酸盐矿物中的高含水量相比，钛铁矿中的水明显偏少。 月球上的水从哪里来？又是如何保存和变化的？这不仅是理解月球演化的关键，也对未来开发利用月球 资源具有重要意义。记者9月1日从中国科学院国家空间科学中心获悉，通过分析嫦娥五号月球样品中的 钛铁矿颗粒，我国科研人员首次揭示钛铁矿在月表水分布与存储中的"双重作用"。相关研究成果在线发 表于《自然-通讯》杂志。 论文通讯作者、中国科学院地质与地球物理研究所研究员田恒次表示，这一发现成功解释了为什么月球 上高钛区域水的日变化更显著：钛铁矿一边高效"造 ...
