最新研究表明, 发现正确的事实可以让阴谋论者产生怀疑,而人工智能正是可以从旁协助的工具。在与人工智能模型GPT-4 Turbo 进行基于证据的对话后,阴谋论者大大降低了他们对所青睐的阴谋论的信任度,而这种新萌生的怀疑态度持续了数月。如此大规模揭开阴谋论信仰网络的举措在以前是无法实现的。

After an evidence-baseddialogue with GPT-4 Turbo, anAI model, conspiracy theoristssubstantially reduced their beliefin favored conspiracies, and thisnewfound skepticism remainedfor months. Unraveling webs ofconspiracy beliefs at scale hasnot previously been possible.

封面图展示的这张照片是一只雌性标准花鼠——一种用于宠物贸易的驯养变种。考虑到老鼠与人类之间长期的密切关系,老鼠成为很好的宠物也就不足为奇了。虽然棕色和黑色的“野生”老鼠确实会传播一些传染病,但近期我们了解到它们具有一些更积极的属性,包括它们技巧熟练、适应性强,甚至很喜欢玩耍。

帕帕哈瑙莫夸基亚海洋垃圾项目(PMDP)的技术人员从西北夏威夷群岛的珊瑚礁中回收了大量废弃的渔具。一项新研究表明,经过数十年从海洋和陆地栖息地清除危险塑料垃圾的不懈努力,濒危的夏威夷僧海豹被塑料缠绕的概率已经被成功降低了。

两个研究小组重点研究了肺炎克雷伯菌的防御相关逆转录酶系统,发现了滚环逆转录的机制。当噬菌体感染后,所产生的串联互补DNA 会转化为双链DNA,导致转录出几乎无限的开放阅读框架(简称neo)mRNA, 该mRNA为一个Neo 多肽编码。这些研究强调了可以通过以RNA 为模板的基因创建扩展基因组编码的潜力。
