黑熊和电视中毒

今年夏天,在离我们仅几公里外的美国西部蒙大拿乡村,每当一只黑熊突然从树林里跑出来,住在那里的朋友就不得不中断用餐,躲到屋子里,看着它走近野餐桌,把盘子舔得干干净净,再喝下两罐啤酒。

接下来几天里,那只熊又掀翻了两个邻居的垃圾桶,并且吓坏了宠物和儿童。美国森林局的护林员们准备了一个笼子,放进了一些咸肉,很快就捉住了这头熊,把它运到了30公里外的荒郊野地中。这头熊被放走前身上做上了标记,表明它曾经找过麻烦。护林员说:"不幸的是,往往是我们的卡车还没回来,熊就已经回来了。一旦尝到了咸肉和啤酒的滋味,就没法再把它赶走了。" 如果做过标记的熊回来捣乱被抓住两次以上,护林员就有权力射杀它。

一只发现了美味的动物抵制不了再次轻易获得美味的诱惑,我们都会为它感到遗憾。除非待在树林里以传统的方式捕猎食物,否则它的生命就已经进入了倒计时,这一点黑熊并不清楚。可那头黑熊是按照自然选择在它基因中种下的智慧来采取行动:富含蛋白质和糖的食物非常有益,而且获取食物消耗的能量越少越好。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  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

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.
