Science News Briefs from around the Globe

来自全球各地的科学新闻简报

Hi, I'm Scientific American podcast editor Steve Mirsky. And here's a short piece from the February 2019 issue of the magazine, in the section called Advances: Dispatches from the Frontiers of Science, Technology and Medicine.

大家好,我是《科学美国人》的播客编辑史蒂夫·米尔斯基。以下内容是本杂志2019年二月刊的一小段节选,摘自我们称之为《进展:来自科学、技术和医学前沿的报告》的部分。

The article is titled Quick Hits, and it's a rundown of some science and technology stories from around the globe, compiled by editorial contributor Emiliano Rodríguez Mega.

文章标题是《一组简讯》,是来自全球某些科学和技术故事的纲要,由社论撰稿人埃米利亚诺·罗德里格斯·梅加整理。

From Greenland: Scientists spotted a 19-mile-wide crater hidden below Hiawatha Glacier in northwestern Greenland. They believe it might represent a meteorite impact, but other experts say more evidence is needed to prove that the crater has an extraterrestrial origin.

来自格林兰岛:科学家们在格林兰岛西北部的希亚瓦沙冰川(Hiawatha Glacier)下发现了一个19英里宽的火山口。科学家们认为这可能是陨石撞击所造成的,但其它专家认为还需要更多的证据来证明这个大坑是由地球外的星球撞击所造成的。

From Chile: One of the driest places on Earth, the Atacama Desert, is losing its microbial life because of unprecedented rains. Frequent rainfall for the past three years has caused the massive extinction of native bacterial species, research suggests.

来自智利:地球上最干旱的地区第一——阿塔卡马沙漠由于前所未有的暴雨,导致沙漠中的微生物不断丧命。研究表明,过去三年频繁的将于导致当地的细菌物种大量灭菌。

From Egypt: An excavation near Cairo yielded dozens of mummified cats. Archaeologists also found two large mummified scarab beetles wrapped in linen and a rare collection of smaller scarab mummies.

来自埃及:开罗附近一次挖掘行动挖掘出了几十具猫的木乃伊。考古学家还发现了两具裹在亚麻布里的大金龟子(圣甲虫)木乃伊以及一组罕见的较小的金龟子木乃伊。

From Palau: The tiny Pacific archipelago became the first country to prohibit the use of sunscreens containing coral-toxic ingredients, including oxybenzone and octinoxate. The measure follows a similar legislative decision in Hawaii that takes effect in 2021.

来自帕劳:这个小小的太平洋群岛成为第一个禁止使用含有“毒害珊瑚礁”成分的防晒护肤品的国家,这些成分包括氧苯酮和辛酸盐。此前,夏威夷也做出了类似的立法决定,将于2021年生效。

From South Africa: Students in Cape Town made bricks using urine from men's toilets, in a biochemical process involving bacteria, calcium and sand. The bricks offer a productive - and odorless - way to recycle human urine.

来自南非:开普敦的学生们用男厕所的尿液制成砖块,这一生化过程涉及细菌、钙和沙子。这种砖提供了一种高效无臭的回收人类尿液的方法。
