Hi, I’m Scott Hershberger, with Scientific American as an American Association for the Advancement of Science Mass Media Science and Engineering Fellow. And here’s a short piece from the November 2020 issue of the magazine, in the section called Advances: Dispatches from the Frontiers of Science, Technology and Medicine. The article is titled 「Quick Hits,」 and it’s a rundown of some stories from around the globe.
嗨，我是斯科特-赫什伯格，作為美國科學美國人協會大眾媒體科學與工程研究員。這是2020年11月號雜誌上的一篇短文 在名為 "進展 "的欄目中：Dispatches from the Frontiers of Science, Technology and Medicine. 這篇文章的標題是 "快速點擊"。這篇文章的標題是 "快速點擊"，它是來自全球各地的一些故事的概述。
Panama: Vampire bats monitored at the Smithsonian Tropical Research Institute have fewer interactions with family and friends when ill, biologists say. But they do not seem to stay apart intentionally—instead sick bats are simply too lethargic to call out to or groom one another.
巴拿馬：生物學家說，史密森熱帶研究所監測到的吸血鬼蝙蝠 在生病時，與家人和朋友的互動較少。但它們似乎並不是故意分開的--相反，生病的蝙蝠只是太昏昏欲睡，無法呼喚或梳理彼此。
Canada: The last fully intact ice shelf in Canada collapsed into the Arctic Ocean this summer. Located in the territory of Nunavut, the Milne Ice Shelf lost 80 square kilometers of ice—40 percent of its area—in just two days.
加拿大：加拿大最後一個完整的冰架在今年夏天坍塌在北冰洋中。位於努納武特地區的米爾恩冰架在短短兩天內失去了80平方公裡的冰層，佔其面積的40%。
Chile: Living 6,700 meters above sea level, a yellow-rumped leafeared mouse found at the summit of the dormant volcano Llullaillaco is the highest-dwelling mammal ever documented. It remains unclear how the animal survives the oxygen scarcity and freezing temperatures at this elevation.
智利：生活在海拔6700米以上的黃臀葉鼠 在休眠火山Llullaillaco的山頂上被發現 是有記錄以來居住率最高的哺乳動物。目前仍不清楚這種動物是如何在這種海拔的缺氧和冰冷的氣溫下生存的。
Russia: An analysis of ancient woolly rhino DNA from Siberia revealed that the population size was stable for thousands of years before the mammal's extinction 14,000 years ago, suggesting that a warming climate—not hunting by humans—most likely triggered its demise.
俄羅斯：對西伯利亞古代毛犀牛DNA的分析顯示，在14000年前這種哺乳動物滅絕之前，種群數量穩定了數千年，這說明氣候變暖，而不是人類的獵殺，很可能是引發其滅亡的原因。
Ethiopia: Paleoanthropologists unearthed a 1.4-million-year old hand ax made from a hippo's leg bone. Together with recently discovered stone tools, the ax indicates that Homo erectus had a diverse tool kit several hundred thousand years earlier than scientists had suspected.
衣索比亞：古人類學家發現了一把140萬年前的手斧 是由河馬的腿骨製成的。連同最近發現的石器，這把斧頭表明，直立人比科學家們懷疑的早幾十萬年就擁有了多樣化的工具箱。
Antarctica: Contrary to researchers' expectations, methane-eating microbes failed to rapidly contain the first methane leak detected on the Antarctic seafloor. The finding means more of the potent greenhouse gas may have been pouring into the atmosphere than previously thought.
南極洲：與研究人員的預期相反，食甲烷的微生物未能迅速控制南極海底首次發現的甲烷洩漏。這一發現意味著更多的強效溫室氣體可能比之前想像的更多地湧入大氣中。
That was 「Quick Hits.」 I’m Scott Hershberger.
