人类是否比切尔诺贝利更糟?

朴茨茅斯——切尔诺贝利核事故已经过去了近三十年,科学界仍在就辐射对反应堆周围生态系统造成的影响争论不休。不久前,我和其他科学家一道对核电站周围无人区的动物进行了研究。

结果令人震惊:无论核辐射对动物造成了怎样的影响,人类居住所造成的后果似乎都更胜一筹。这样的结果不容回避地提醒人们:人类在栖息地的简单活动比21世纪最严重的环境灾难还要糟糕。

我们针对方圆2,200平方公里(合850平方英里)的白俄罗斯“波萊谢国家放射生态保护”隔离区的栖息动物进行了研究。灾难发生前,上述地区有22,000人,92座村庄,主要以耕种和林业资源开发为主。事故发生几天后,政府对地区居民及其所养殖的动物进行了疏散,以保护它们免受高剂量辐射。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  2. The Great US Tax Debate

    ROBERT J. BARRO vs. JASON FURMAN & LAWRENCE H. SUMMERS on the impact of the GOP tax  overhaul.


    • Congressional Republicans are finalizing a tax-reform package that will reshape the business environment by lowering the corporate-tax rate and overhauling deductions. 

    • But will the plan's far-reaching changes provide the boost to investment and growth that its backers promise?

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
