蚊子的威胁

斯坦福—蚊子传播的疾病每年要多走数百万人的生命,因此受苦的人数更要多得多。2012年,据估计有2.07亿人罹患疟疾,其中造成627,000人死亡。登革热是热带和亚热带的主要致死病因,每年感染的人数更是高达1亿人。此外,每年还有约200,000人罹患黄热病,造成全球30,000人死亡。

染上令人痛苦甚至致命的疾病只需要被携带病菌的蚊子叮上一口,而蚊子以令人咋舌的速度繁殖和增加着。对于登革热等疾病和西尼罗河病毒,目前还没有疫苗或药物可以治疗,而对疟疾等疾病的治疗在许多高风险地区也难以获得,因此我们急需更有效的措施控制蚊子数量。

好消息是,一项极有希望的新技术已经进入了实地测试。现在,需要政府机构促进它的发展。

    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.
