Hi, I'm Scientific American podcast editor Steve Mirsky. And here's a short piece from the July 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》播客编辑史蒂夫·米尔斯基。下面是本杂志2019年7月刊的一篇短文，摘自“进展：科学、技术和医学前沿快报”版块。

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 Jim Daley. 

这篇文章名为《要闻快讯》，汇集了全球各地科学和技术新闻报道的摘要，由编辑撰稿人吉姆·戴利汇总。

From Guatemala:

危地马拉

Archaeologists unearthed¹ the largest known Mayan figurine factory. The more than 1,000-year-old workshop mass-produced intricate statues that were likely used in diplomacy² as gifts to allies.

考古学家挖掘出目前已知最大的玛雅雕像作坊。这家有着1000多年历史的作坊大量生产精致的小雕像，这些雕像可能在外交中作为礼物赠送给盟友。

From Nepal:

尼泊尔

Researchers confirmed the nation's first recorded tornado³, which occurred during a devastating⁴ storm in March. The team relied on satellite imagery and posts on social media to make the identification.

研究人员证实，该国第一次有记录的龙卷风发生在今年3月一场毁灭性风暴期间。研究团队依靠卫星图像和社交媒体帖子进行鉴定。

From Antarctica:

南极洲

Emperor penguins⁵ have abandoned one of their biggest breeding colonies, possibly because of sea-ice loss. Biologists found that the population, which reached about 25,000 breeding pairs of birds in 2010, collapsed⁶ in 2016 and has not rebounded⁷ since.

帝企鹅已经放弃了它们最大的繁殖地之一，原因可能是海冰减少。生物学家发现，该种群在2010年有约2.5万个繁殖对，但数量在2016年大幅减少，此后也未反弹。

From China:

中国

The Large High Altitude Air Shower Observatory⁸ on the eastern edge of the Tibetan Plateau began operating in April. Located some 4,400 meters above sea level, the observatory will study high-energy cosmic rays.

位于青藏高原东缘的大型高海拔宇宙线观测站于今年4月开始运行。该观测站位于海拔约4400米处，将研究高能宇宙射线。

From Australia:

澳大利亚

The government announced it will not regulate gene-editing technology provided it does not introduce new genetic⁹ material to target sites in the genome. Editing human embryos¹⁰ used for reproduction is still banned, however.

澳大利亚政府宣布，如果基因编辑技术不向基因组靶标位点引入新的遗传物质，政府就不会对基因编辑技术进行监管。然而，以繁育目的编辑人类胚胎的行为仍被禁止。

And From Kenya:

肯尼亚

Paleontologists have identified a fossil jawbone in the Nairobi National Museum that came from a previously¹¹ unknown giant carnivore, which roamed Africa 22 million years ago. The predator¹² was likely larger than a polar bear and had fangs¹³ the size of bananas.

古生物学家在内罗毕国家博物馆发现了一块下颌骨化石，来自2200万年前在非洲游荡的一种未知的巨型食肉动物。这种食肉动物的体型可能比北极熊还要大，有着香蕉般大小的尖牙。

That was Quick Hits, by Jim Daley.
