Combatir la plaga del mosquito

STANFORD – Cada año, enfermedades transmitidas por mosquitos matan a millones de personas y causan sufrimiento a muchas más. Se estima que en 2012 hubo 207 millones de casos de malaria, de los que unos 627.000 fueron fatales. En tanto, el dengue es una de las principales causas de enfermedad y muerte en las regiones tropicales y subtropicales; cada año, hasta 100 millones de personas resultan infectadas. Y se estima que en todo el mundo se producen unos 200.000 casos de fiebre amarilla por año, de los que 30.000 son fatales.

Una sola picadura de un mosquito infectado basta para transmitir una infección debilitante o mortal; y la rapidez con que se reproducen los mosquitos es sorprendente. Para enfermedades como el dengue y el virus del Nilo occidental no existen vacunas ni medicamentos, y los tratamientos para enfermedades como la malaria no son fácilmente accesibles en muchas de las áreas en riesgo, de modo que es imperioso hallar mecanismos más eficaces para controlar las poblaciones de mosquitos.

Felizmente se ha inventado una nueva tecnología que promete dar buenos resultados y ya está lista para la prueba en campo. Facilitar su desarrollo depende ahora de los organismos gubernamentales.

    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.
