130亿年前的第一个分子？蟑螂机器人能干嘛？新冠后大脑为何集体老化？

冬天需要池塘的海狸们为什么会集体北迁？130亿年前的宇宙中第一个分子是什么？冬眠动物的绝活竟然只是一个基因开关的变化？什么样的脑回路才会设计出像蟑螂一样的机器人？即使你侥幸没得过新冠，为什么也可能出现大脑老化？今天的3分钟科学漫游，我们一起看看这些领域知识探索的边界在哪里！主播：奶树关于「3分钟科学漫游」：这是一档关于科学知识与科学漫游的播客栏目，我们希望能在几分钟左右时间里，给大家分享一些有趣又有用的科学新闻动态，带大家一起了解科学研究的最前沿，探索知识领域的边界线！参考资料：Tape K D, Speed J D M.
