Science News Briefs from around the World

世界各地新闻简报

Hi, I’m Scientific American podcast editor Steve Mirsky. And here’s a short piece from the February 2020 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。这是该杂志2020年2月的一篇短文,题为《前进:来自科学、技术和医学前沿的报道》。

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.

这篇文章的标题是“快速点击”,是由助理新闻编辑萨拉·卢因·弗雷泽编辑的来自全球各地的一些科技报道的摘要。

From the U.S.:

Off the California coast, scientists measured a blue whale’s heart rate for the first time, using a device attached to the animal's skin by suction cup. The heart, likely weighing hundreds of pounds, beats from two to 37 times per minute, varying dramatically between diving, feeding and surfacing.

来自美国:

在加利福尼亚海岸外,科学家们利用一种通过吸盘附在蓝鲸皮肤上的装置首次测量了一头蓝鲸的心率。这颗可能重达数百磅的心脏每分钟跳动2到37次,在潜水、进食和浮出水面之间跳动次数变化很大。

From Peru:

Researchers analyzing satellite and imaging data have found 143 new Nazca lines—large line drawings of humans, animals and symbols etched into the Peruvian landscape millennia ago. They include a humanoid figure 16 feet across, spotted by IBM’s Watson AI system.

从秘鲁:

研究人员分析了卫星和图像数据,发现了143条新的纳斯卡线条,这些线条是数千年前刻在秘鲁地貌上的人类、动物和符号的大型线条图。它们包括由IBM的沃森人工智能系统发现一个16英尺宽的人形。

From Brazil:

Despite the long dry spells in Brazil’s Caatinga region, scientists found the tree Hymenaea cangaceira drizzles copious nectar from flowers to attract pollinating bats; a full-size tree can release 240 gallons of the stuff, with 38 distinct scent compounds, over a single dry season.

从巴西:

尽管巴西的Caatinga地区长期干旱,科学家们发现树Hymenaea cangaceira从花中滴下丰富的花蜜来吸引授粉的蝙蝠;在一个干燥的季节里,一棵正常大小的树可以释放240加仑的此种物质,含有38种不同的气味化合物。

From Norway:

Archaeologists’ ground-piercing radar found a Viking-era ship, surrounded by a filled ditch, lurking below the soil of a western Norway farm. It was once within a burial mound.

从挪威:

考古学家通过地面穿透雷达发现了一艘维京时代的船只,这个船只被一个填满的沟渠包围着,潜伏在挪威西部一个农场的地下。它曾经在一个土堆里。

From Jordan:

Researchers uncovered a two-horned figure in early Islamic ruins that may be the earliest chess piece ever found. The roughly 1,300-year-old object matches a rook found in an Iranian chess set from about 400 years later.

从约旦:

研究人员在早期的伊斯兰废墟中发现了一尊双角雕像,这可能是迄今为止发现的最早的国际象棋棋子。这个约有1300年历史的雕塑与400年后在伊朗国际象棋中发现的一辆车相匹配。

From Ethiopia:

Microbes thrive in many of Earth’s harshest environments, but researchers found no life at all in briny, scorching, acidic pools near Ethiopia’s Dallol volcano. Knowing boundaries for life’s adaptation helps to narrow the search for Earth-like life on other planets.

从埃塞俄比亚:

微生物在地球上许多最恶劣的环境中茁壮成长,但研究人员在埃塞俄比亚的宽干谷火山附近的盐碱地、灼热的酸性水池中根本没有发现生命。了解生命适应环境的界限有助于缩小对其他行星上类似地球生命的搜寻范围。
