中国女孩疑在美机场被绑
Chinese girl believed to be abducted from US airport
A 12-year-old girl who was visiting the United States from China was believed to be abducted by a woman at Ronald Reagan Washington National Airport on Thursday morning, officials say.
据官方消息，当地时间8月2日上午，一名从中国来美国旅游的12岁女孩疑似在华盛顿里根国家机场遭到一名女子绑架。
The girl, JinJing Ma, is believed to be in "extreme danger," Virginia State Police said in a statement. The FBI is involved in the investigation, and state police said they are contacting the Chinese embassy.
弗吉尼亚警方发布警报说，这位名叫马金晶（音译）的女孩处境“极度危险”。联邦调查局已介入调查，弗吉尼亚警方称，正在联系中国大使馆。
Law enforcement officials in the DC area issued an Amber Alert.
华盛顿地区执法人员发布了安伯警报（译者注：美国儿童安全警报系统）。
Ma was last seen at the airport at 8:15 a.m. She was traveling with a group and met with a middle-aged woman, who also was visiting from China.
马金晶于8:15最后一次出现在里根国家机场。她随一个中国旅游团来美旅游，与一名中年女性会合，这名女性也是从中国来美旅游。
The girl and the woman both changed clothes, walked to the arrivals area of the airport and disappeared out of the view of security cameras, police said.
警方表示，马金晶和这名女性都换了衣服，两人一起走到机场的到达区后，最终从监控中消失。
They are believed to be riding in a white 2016 or 2018 Infiniti QX70 with New York plates that a man is driving. Investigators are working to identify the license plate number, the Washington Metropolitan Airports Authority said late Thursday night.
两人被看到乘坐一辆挂着纽约牌照的白色2016或2018款英菲尼迪QX70汽车，由一名男子驾驶。华盛顿都会区机场管理局2日晚表示，侦查员正在识别车牌号。

MH370调查报告
MH370 report
The head of Malaysia’s civil aviation regulator has resigned after an official report found failings in air traffic control when flight MH370 disappeared.
一份关于MH370航班客机失事的官方调查报告称，飞机失事时，航空管制中心存在疏漏，马来西亚民航局局长已提出辞职。
In a long-awaited report released on Monday, the official investigation team pointed to numerous lapses by air traffic controllers in both Malaysia and Vietnam, which ensured the plane was missing for about 20 minutes before an alert was sent.
这份众盼已久的报告于7月30日发布，官方调查团在报告中指出，马来西亚和越南空管部门存在诸多过失，直到飞机大约失联20分钟后才加以确认并发出警报。
In the 495-page report, investigators said they still did not know why the plane vanished, leaving families of those onboard devastated and highly critical of the investigation.
调查人员在495页的报告（译者注：该报告共822页，主体部分共495页）中依然没有查明飞机失踪的原因，乘客家属对调查结果极为不满，陷入崩溃。
The safety investigating team, however, did officially conclude that the course of the Malaysia Airlines aircraft was changed manually, rather than due to autopilot mechanisms.
但安全调查团正式宣布，MH370被人为改变航线，并非由于自动驾驶仪出现机械故障。
After investigations demonstrated that the pilot had been both adequately trained and under no pressures or mental strain that could have led him to crash the plane on purpose in a suicide mission, Dr Kok Soo Chon, the investigator in charge of the MH370 safety investigation, said “interference by a third party” could be a reason the jet suddenly diverted off course.
调查表明，两名飞行员均受过严格训练，不存在压力或精神紧张，以致作出故意坠机的自杀举动。负责MH370安全调查的郭师传称，“第三方干扰”或许是飞机突然偏离航线的原因。
The transport minister, Anthony Loke, said on Monday that “the aspiration to locate MH370 has not been abandoned” and vowed to take action against any misconduct committed based on the findings.
马来西亚交通部长安东尼·洛克7月30日表示，“不会放弃搜索MH370的位置”，并采取行动坚决反对调查结果涉及的不当行为。

拼多多涉假遭调查
Pinduoduo probed over alleged fake goods
China's markets regulator said on Wednesday it has asked Shanghai regulators to investigate online discounter Pinduoduo Inc following media reports of counterfeit goods and intellectual property infringements.
据媒体报道，折扣电商拼多多公司涉嫌销售侵权假冒商品，中国市场监管总局8月1日表示，已要求上海相关监管部门展开调查。
The move comes after the Chinese e-commerce start-up raised $1.63 billion last week in the second-biggest U.S. listing by a Chinese firm this year, which valued the company at $23.8 billion.
上周，这家中国电商初创公司融资16.3亿美元（约合人民币111亿元），市值达238亿美元（约合人民币1623亿元），成为今年在美国上市的第二大中国公司。
Regulators will interview the Shanghai-based platform's operators and will deal seriously with any illegal practices found on the platform, the State Administration for Market Regulation said on its website.
国家市场监管总局官网发布消息称，监管部门将约谈上海拼多多平台经营者，只要平台构成违法，将依法严肃处理。
Pinduoduo is known for running large campaigns with extremely low-priced products to lure consumers – and has faced criticism for allowing misleading goods to be sold to consumers in some instances, mostly in China’s countryside.
拼多多因用价格极低的商品吸引消费者而声名鹊起，同时也因向消费者（主要集中在中国农村地区）出售山寨商品而备受诟病
Serial entrepreneur Huang Zheng, the founder of Pinduoduo, said counterfeit goods remain an unavoidable problem in China amid the steady development of the country’s online retail market.
拼多多创始人、连续创业者黄峥表示，在中国线上零售市场平稳发展的今天，山寨货依然是不可避免的问题。

人造单染色体真核细胞
man-made single-chromosome eukaryote
Brewer's yeast, one-third of whose genome is said to share ancestry with humans, has 16 chromosomes. However, Chinese scientists have managed to fit nearly all its genetic material into just one chromosome while not affecting the majority of its functions, according to a paper released Thursday on the website of the journal Nature.
具有16条染色体的酿酒酵母中有1/3的基因与人类基因同源。然而，8月2日在《自然》杂志网站上发表的一篇论文称，中国科学家成功将酿酒酵母几乎所有的遗传物质整合为单条染色体，且不影响其大部分功能。
Qin Zhongjun, a molecular biologist at the Center for Excellence in Molecular Plant Sciences of the Shanghai Institute of Plant Physiology and Ecology under the Chinese Academy of Sciences, and his team used CRISPR-Cas9 genome-editing to create a single-chromosome yeast strain, the paper said.
中国科学院上海植物生理生态研究所分子植物科学卓越创新中心的分子生物学家覃重军和他的团队使用CRISPR-Cas9基因组编辑技术创建了单条染色体酵母菌株。
Yeast is a type of eukaryote, which also includes humans, plants, and animals. Humans have 46 chromosomes, whereas male jack jumper ants have just one. It seems that the number of chromosomes of a eukaryote has no correlation with the amount of genetic information they possess, the paper said.
酵母和人类、动植物一样，都是真核生物。人类有46条染色体，而雄性杰克跳蚁只有一条。论文提到，真核生物的染色体数目似乎与他们所携带的遗传信息数量没有相关性。
"It overturns the traditional view that gene expression is determined by the structure of chromosomes," Qin said.
覃重军说：“这颠覆了染色体结构决定基因表达的传统观念。”
The research may also pave the way for new man-made species in the future. "Yeast has great tolerance in genetic modification, and it is possible to add new chromosome segments to the genome. Researchers can make bolder attempts。" he said.
这项研究或许也为未来新的人造物种铺平了道路。“酵母对基因改造有很强的耐受性，并有可能在基因组中增加新的染色体片段。研究人员可以进行更大胆的尝试。”他说。
