Hi, I'm Scientific American podcast editor Steve Mirsky. And here's a short piece from the November 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11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 intern¹ Jennifer Leman.

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，由实习编辑詹妮弗·莱曼汇总。

From Canada:

加拿大：

In the famed Burgess Shale² rock formation, paleontologists discovered hundreds of fossils of a horseshoe crab–shaped, prehistoric³ predator⁴ that lived in the ocean 506 million years ago. It measured up to a foot long.

在著名的伯吉斯页岩中，古生物学家发现了生活在5.06亿年前海洋中的、史学鲎状捕食者的数百块化石。其尺寸可达一英尺长。

From Tanzania:

坦桑尼亚：

Marine⁵ biologists discovered a colorful fish species, dubbed⁶ the vibranium fairy wrasse, during a biodiversity assessment⁷ of largely unstudied deep reefs off Zanzibar's coast.

在对桑给巴尔海岸附近大部分未经研究的深海群礁进行生物多样性评估时，海洋生物学家发现了一种彩色的鱼，并为其命名为“振金仙女濑鱼”。

From Colombia:

哥伦比亚：

Scientists confirmed a destructive fungus⁸ targeting banana plants has arrived in the country. No treatment is available, so officials put potentially infected crops under quarantine to stop its spread.

哥伦比亚科学家证实，一种以香蕉植株为目标的破坏性真菌已抵达该国。由于没有有效的处理方法，该国官员隔离了有感染可能的作物，以阻止真菌传播。

From Mexico:

墨西哥：

Researchers have rationed⁹ electricity and cut temporary employees' jobs after Mexico's president lowered funding for federal institutions by 30 to 50 percent in certain budget items, including those supported by the National Council of Science and Technology.

研究人员限制了用电量并降低了临时工人的工作量，此前墨西哥总统将联邦机构在某些预算项目中的资金削减了30%至50%，受影响项目包括国家科学技术委员会支持的项目。

And from Cameroon and Equatorial Guinea:

喀麦隆和赤道几内亚：

Scientists found that Goliath frogs, which are Earth's largest living frogs and can be longer than an American football, construct protected ponds for their young by pushing heavy rocks across streams. They live only in this region.

科学家发现，体型可大于美式足球、世界上现存最大的蛙——非洲巨蛙，会推动大石头来拦住溪流，为后代建造受保护的池塘。让它们只在此处生活。

That was "Quick Hits," by Jennifer Leman.
