据美国太空网近日报道，一项新研究称，火星上的火星震可能由火星上的地下水引发，未来的火星探险者或许可以借助火星震找到并获取宝贵的资源——水。
加州大学伯克利分校行星科学家迈克尔·曼加和他的同事们表示，火星这颗红色星球上的浅层地震，例如最近由美国国家航空航天局(NASA)“洞察”号着陆器探测到的地震，可能是水导致地下压力增加、引起构造断层滑动造成的。

白垩纪的一种混种螃蟹化石以奇特的解剖特征困扰着研究人员，后者在哥伦比亚安第斯山脉发现了约70块螃蟹化石。9000万年前，当这些动物活着时，安第斯山脉是一片浅海。“我们开始研究这些化石，发现它们拥有类似幼虫的眼睛、虾的嘴巴、蛙蟹的爪子以及龙虾的甲壳。”加拿大阿尔伯塔大学的Javier Luque介绍说，“我们已经知道了典型螃蟹的样子，而这些新化石打破了所有这些规则。”
