China's Mengtian lab module docks 

梦天实验舱与空间站组合体在轨完成交会对接

The Mengtian lab module has successfully docked with China's Tiangong space station, according to the China Manned Space Agency. Mengtian, Tiangong's second lab module, docked with the front port of Tianhe, the space station's core module, at 4:27 am Tuesday (Beijing Time) after it entered its planned orbit. The whole process of rendezvous and docking took approximately 13 hours. Later, Mengtian will conduct transposition as planned. The Mengtian module, together with the Tianhe core module and Wentian lab module, will form the space station's basic T-shaped configuration.

据中国载人航天工程办公室消息，梦天实验舱与中国空间站“天宫”组合体在轨完成交会对接。梦天实验舱是中国空间站的第二个科学实验舱，发射入轨后，于北京时间周二（11月1日）4时27分成功对接于天和核心舱前向端口。整个交会对接过程历时约13小时。中国载人航天工程办公室消息称，后续将按计划实施梦天实验舱转位。梦天实验舱将与天和核心舱、问天实验舱形成空间站“T”字基本构型组合体。

Fossils show how fish evolved into humans

“从鱼到人”有证据了！化石表明人类如何从鱼类演化而来

Chinese scientists have discovered fossils that could fill gaps in the story of how humans evolved from fish. According to four articles published in the journal Nature in late September, Chinese researchers found fish fossils that provide the “missing link” about the origin of the jaw, a key trait 99.8 percent of vertebrate species have.

中国科学家发现一批化石，完善了人类如何从鱼类演化而来的进化故事。根据9月下旬发表于《自然》杂志的四篇文章，中国研究人员发现的古鱼化石填补了有颌类起源的“缺失环节”，地球上现存99.8%的脊椎动物都具有颌骨这一关键特征。

Zhu Min, a lead researcher of the studies from the Chinese Academy of Sciences, said the findings drew a large amount of interest in the science world due to the importance of jaws in animal evolution. However, the rise of the jaw had been a mystery due to a lack of sufficient fossil evidence to show jawed vertebrates lived 450 million years ago. 

领衔该研究的中国科学院朱敏院士指出，有颌类在动物演化史中至关重要，因此这些发现在科学界引发了极大兴趣。然而，有颌类的崛起一度笼罩在迷雾中，由于化石实证不够充分，科学家无法证明4.5亿年前已经出现有颌脊椎动物。

The latest findings presented a set of five surprisingly well-preserved fish fossils that included three whole-bodied fish, helping scientists paint a more accurate evolutionary picture of the origin of the jaw. The fish fossils were discovered at two sites in Chongqing and Guizhou, whose strata date back to the Silurian Period that began around 440 million years ago. 

朱敏院士团队的最新研究成果展示了五种保存十分完好的古鱼化石，其中包括三种完整保存的鱼类，帮助科学家描绘出了更准确的有颌类起源进化图。这些古鱼化石是在重庆、贵州等地志留纪早期距今约4.4亿年的地层中发现的。

Dog ‘smiles’ may not indicate happiness

狗不会笑，而是用其他方式表现开心

Some dogs just look like they’re smiling all the time - but that huge grin on their face may not actually mean they’re happy. Carolyn Menteith, a canine behaviorist, said "unlike us, dogs don’t usually smile with their mouths. "When a dog smiles, their tail is relaxed but waving, their eyes are soft, their ears relaxed and their body is often wiggling with happiness.”

有些狗狗看起来好像一直在笑，但它们脸上大大的“笑容”或许并不真的表示它们很开心。犬类行为学家凯洛琳‧曼特斯说：“和我们不同，狗狗通常不用嘴巴来笑。”当狗狗笑时，它们的尾巴是放松且晃动的，它们的眼神很柔和，耳朵会放松下来，身体通常会因为开心而扭来扭曲。

Some dogs are noisier than others and so if they get really excited and playful, they might bark, yip, or even huff - especially in an attempt to get another dog or a person to play - but this isn’t laughter. Interestingly, dogs do seem to recognize laughter in humans and know it is positive - and some dogs seem to go out of their way to encourage their owners to laugh.

有些狗狗则比其他狗吵闹，在它们特别兴奋和玩耍的时候，可能会大声吠叫、尖声叫或者喷气，尤其是为了让其他狗或人来一起玩时，但这不是在笑。有趣的是，狗狗似乎的确能够分辨出人类的笑声并且知道这是好事，而有些似乎还会想尽办法把主人逗笑。
