种族药品的复兴

事情本不应该如此。2000年春天,Francis Collins和Craig Venter在一次白宫新闻发布会上宣布:人类基因组的首次测绘排序工作已经完成。得到了比尔·克林顿总统和托尼·布莱尔首相的首肯,Collins和Venter公开宣布在分子级别进行种族划分没有意义,因为人类99.9%的DNA完全一致。全世界新闻媒体都被科学对种族主义思想的有力驳斥所深深吸引,争先恐后地报导了这一消息。

但这样的结论为时尚早。尽管99.9%的人类基因完全相似,但30亿对基因的庞大基数却为任何两个个体留出了300万的差异空间(即单核苷酸多态性,也叫SNP's)。运用无比强大的最新电脑技术,科学家们将注意力集中到剩下0.1%的基因差异之中。

为什么仅仅几天之后,科学就从否认存在人类种族差异转而采取了妥协的立场?

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
