美国的致命科学恐慌

纽约—如今,一场罕见的高传染性致命疾病正在美国蔓延,自今年年初以来已经感染了100多人,并由数千人属于高危人群。这不是埃博拉式的末日情景——许多人在五个月前美国确诊首例埃博拉后担心这一点。这是麻疹的死灰复燃——2000年,美国疾病控制和预防中心宣布,由于有了高效安全的疫苗,这种疾病已被根除。哪里出了问题?

2000年以来,美国麻疹病例大部分归因于旅行者携带入境。但是,近几年来,麻疹日益普遍,2013年病例数达到了150以上,去年又增加至644人——这是20世纪90年代以来全年报告人数最多的一年。今年已经有了改写这一纪录的趋势。

麻疹病例的激增大部分可以解释为未接种儿童数量的增加。美国人以沉重的代价了解到,针对疫苗的没有科学根据的怀疑是极其危险的。

  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.

    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.

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.
