利用微痕分析与残留物检测技术，高星团队确认云南甘棠箐遗址中35件木质材料系古人类精心制作、长期使用的专业工具，主要用于挖掘植物根茎等作为食物。为测定这些木器的年代，古生物地层学、古地磁学、光释光和电子自旋共振等多种方法被交叉使用，最终检验、确认它们制作于距今约30万年前的旧石器时代早期，是迄今东亚地区所见最古老的木器。这项发表于国际知名学术期刊《科学》上的研究，有力反驳了过往认为中国旧石器时代技术发展迟缓的观点。

We haven't had a new film from Gore Verbinski for nine years. But the director who brought us the first three Pirates of the Caribbean movies, the nightmare-inducing horror of The Ring (2002), and the Oscar-winning hijinks of Rango (2011) is back in peak form with Good Luck, Have Fun, Don't Die. It's a darkly satirical, inventive, and hugely entertaining time-loop adventure that also serves as a cautionary tale about our widespread online technology addiction.
