¿Deberíamos vivir hasta cumplir 1.000 años?

PRINCETON – ¿En cuáles problemas deberíamos enfocar la investigación en medicina y ciencias biológicas? Existe un argumento sólido a favor de luchar contra las enfermedades que matan a más personas – enfermedades como la malaria, el sarampión y la diarrea, que son las que matan a millones de personas en los países en desarrollo, pero a muy pocas en el mundo desarrollado.

Los países desarrollados, sin embargo, dedican la mayor parte de sus fondos de investigación a las enfermedades que sufren sus ciudadanos, y es muy probable que esta situación continúe así en el futuro previsible. Teniendo en cuenta esta restricción, ¿qué avance médico sería el que logre más en cuanto a mejorar nuestras vidas?

Si su primer pensamiento es “una cura para el cáncer” o “una cura para las enfermedades cardiacas”, piénselo de nuevo. Aubrey de Grey, director científico de la fundación SENS y el defensor más destacado del mundo en el campo de la investigación anti-envejecimiento, afirma que no tiene sentido gastar la mayor parte de nuestros recursos médicos en tratar de luchar contra las enfermedades de la vejez, sin combatir el envejecimiento en sí. Si curamos una de estas enfermedades, los que hubieran muerto a causa de la misma pueden esperar sucumbir a causa de otra, unos pocos años más adelante. Por lo tanto, el beneficio es modesto.

    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.
