据《自然》杂志24日报道，美国斯托瓦斯医学研究所团队首次精确定位了人类染色体在形成罗伯逊易位时的融合点。这项研究具有里程碑式的意义，不仅揭 示了这类染色体融合是如何形成并保持稳定的，还指出曾被认为是"垃圾"的重复DNA，可能在基因组组织和进化中发挥核心作用。 人类染色体通常被描绘成两两配对的"整齐队列"。但在大约每800人中，就有一人出现不同寻常的情况，即两条染色体"牵手"融合，形成一种特别的结构， 这就是所谓的罗伯逊易位。这种现象长期以来困扰着科学家。 罗伯逊易位携带者往往并不自知。他们大多健康，但可能会出现不孕或流产的情况。当他们有子女时，孩子罹患唐氏综合征的风险也会升高。 此次，团队利用一种称为"长读长测序"的DNA测序技术，首次获得了完整的罗伯逊易位染色体序列。与传统测序方法不同，长读测序能读取高度重复的 DNA区域，使科学家看清了此前难以解析的"盲区"。团队比较了3条罗伯逊易位染色体与正常染色体，发现它们的断裂点均位于一种称为SST1的重复DNA序 列中。当这些SST1序列在细胞核仁中靠近时，可能发生融合，形成罗伯逊易位染色体。 罗伯逊易位的形成机制是两条染色体的长臂融合，而短臂丢失。这样会留下45 ...

这一发现对未来自然灾害监测或有重要意义。过去，科学家通常将每个火山视为独立系统，但这项 研究揭示，火山之间可能通过深层岩浆网络相互连接，甚至彼此影响。 圣托里尼和科隆博这对"海底双胞胎"，或许只是冰山一角。一些火山活跃区可能也存在类似的机 制。例如，夏威夷、冰岛和堪察加半岛等地的火山，背后或许也有"共享岩浆源"的影子。 这项研究由德国亥姆霍兹协会地球科学中心与基尔海洋中心主导。科学家借助卫星雷达（InSAR） 技术，精确测量了地表的微小隆起。这些数据如同"地球的脉搏"，揭示了地下岩浆的流动轨迹。 从2024年7月起，卫星就监测到圣托里尼岛的地表开始缓慢抬升；到2025年初，部分地区已隆起数 厘米。这表明，在地表以下约3.8公里深处，一个巨大的岩浆房正在悄悄"注浆"，就像一个缓慢膨胀的 气球。 但真正的转折点出现在今年1月27日。科学家发现，海底的科隆博火山区域突然出现了地面下沉的 迹象。结合地震数据，他们推断：一股岩浆正从科隆博下方约7.6公里深处，向圣托里尼方向迁移。这 就像两个连通的水袋，当一个充水膨胀时，另一个就会缩小。 这是一场岩浆争夺战。当圣托里尼的岩浆房压力升高，它就从共享的岩浆管道中吸走了本可能 ...
