>Wealth gap widens in US
美国贫富差距进一步扩大

The roaring stock market and crypto gains created more than a million new millionaires in the US last year, according to a new report.
新报告称，去年的股市繁荣和加密货币升值在美国新创造出100多万个百万富翁。

The number of Americans with $1 million or more in investible assets surged to a record 14.6 million in 2021, up from 13.3 million in 2020 according to a report from wealth research firm Spectrem Group.
财富调研公司斯佩特兰集团的报告指出，2021年，可投资资产超百万美元的美国人数量从2020年的1330万人飙升至创纪录的1460万人。

The growth rate of over 10 percent was the strongest in years, boosted by trillions of dollars in wealth created by the stock market, crypto and other assets.
超10%的百万富翁增长率是近年来最高的，这得益于股市、加密货币和其他资产创造的数万亿美元财富。

Gains at the top also widened the wealth gap in the US.
顶级富豪财富的增长也扩大了美国的贫富差距。

The share of wealth held by the top 1 percent grew to a record 32 percent last year, according to the Fed.
美联储的数据显示，最富有的1%美国人拥有的财富在去年增长至创纪录的32%。

>Scientists breed youngest human cells
科学家诱导出人类全能干细胞

A team of researchers from China, Britain and Bangladesh converted pluripotent stem cells, or an "adult" version of early embryonic cells, back to a more "juvenile" version of cells with developmental potential, tantamount to fertilized eggs in their day 3 developmental stage.
由中国、英国和孟加拉国的科学家组成的研究团队将人类多能干细胞，即“成年”版本的早期胚胎细胞，转化成具有发育潜力的、更“年轻”的干细胞，即相当于受精卵发育3天状态的全能干细胞。

Totipotent 8-cell stage embryo-like cells recreate the embryonic state of a fertilized egg after only three divisions, making them the youngest human cells acquired in vitro ever known, Li Wenjuan from the Chinese Academy of Sciences said.
中国科学院的李文娟博士表示，这些全能性的8细胞期胚胎样细胞重建了受精卵仅分裂3次后的胚胎状态，这是迄今为止在体外诱导获得的“最年轻”的人类细胞。

Cells described as "totipotent" mean that they have the potential to create all types of cells within embryonic and extra-embryonic tissues, according to researchers.
据介绍，全能性细胞意味着它们有潜力分化出胚胎和胚胎外组织中所有类型的细胞。

"These cells can not only differentiate into placental tissue but also potentially develop into more mature organs," Li said.
李文娟博士说，这种细胞可以分化为胎盘组织，并可能发育为更成熟的各类身体组织。
