介绍： Hi, I'm Scientific American podcast editor Steve Mirsky. And here's a short piece from the December 2019 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 science and technology stories from around the globe, compiled by assistant news editor Sarah Lewin Frasier.
From Spain:
Summer's powerful drought revealed a more than 4,000-year-old oval of at least 100 standing stones called the Dolmen of Guadalperal, which had been submerged since 1963 in an engineered reservoir.

From Russia:
Scientists identified a small group of Nordmann's greenshanks, among the most endangered shorebirds, in a bog in Russia's far eastern region. They helmed the first in-depth study of the bird since 1976 and are the first ever to capture a photograph of an adult on a nest.

大家好，我是《科学美国人》播客编辑史蒂夫·米尔斯基。这里有一件2019年未完成的小事，收录在本杂志2019年12月刊的一篇短文，摘自“进展：科学、技术和医学前沿快报”版块。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，由助理编辑莎拉·莱温·弗雷泽汇总。
西班牙：
夏季的严重干旱使拥有4000多年历史的、至少由100块立石组成的椭圆形阵列重见天日，这个阵列被称为“瓜达帕拉尔的多尔门”，自1963年就被淹没在一座工程水库中。
俄罗斯：
科学家在俄罗斯远东地区的一个沼泽地里发现了一小群小青脚鹬，它们是最濒危的滨鸟之一。他们主导的这项研究是自1976年以来对小青脚鹬进行的首个深入研究，也是有史以来第一次在鸟巢中拍摄到成年鸟的照片。
