La extinción deliberada de especies es un peligro

HONOLULU – Hay en marcha una cínica campaña para promover el uso de una nueva tecnología, poderosa y preocupante, conocida como “impulsor genético” (gene drive), como herramienta conservacionista. No es la modificación genética común y corriente (la creación de organismos “transgénicos”), sino algo radicalmente nuevo, consistente en la activación de “mutaciones genéticas en cadena” capaces de modificar sistemas vivos en formas inimaginables.

El impulsor genético es la próxima frontera de la ingeniería genética, la biología sintética y la edición de genes. Esta tecnología permite invalidar las reglas normales de la herencia genética, para asegurar que un rasgo particular injertado artificialmente en el ADN de un organismo mediante tecnología de edición de genes avanzada se transmita a todas las generaciones siguientes, alterando así el futuro de toda la especie.

Es una herramienta biológica con un poder nunca antes visto. Pero en vez de detenerse a pensar bien las implicaciones éticas, ecológicas y sociales aplicables a esta tecnología, muchos se han lanzado a una feroz campaña para promoverla como herramienta de conservación de especies.

    A Tax Plan that’s All Stuffing?

    US President Donald Trump has set a Christmas deadline for enacting the Republican tax plan, and economic observers are virtually unanimous in judging it a turkey. A scheme that squeezes the middle class and blows out the fiscal and current-account deficits may pass, but it will never fly.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    The Dangers of Nuclear Bombast

    US President Donald Trump has refused to recertify the 2015 Iran nuclear deal, an agreement that he once predicted would "lead to a nuclear holocaust." Unfortunately, by creating more perverse incentives for hostile regimes to pursue nuclear armaments at all costs, Trump has made the nightmare scenario he fears even more likely.

    Europe’s New Eastern Question


    Insider Interview

    • With right-wing populists ascendant in Poland and Hungary, and gaining ground elsewhere in the European Union, politics in some parts of the West looks increasingly like politics in Russia.

    • Sławomir Sierakowski, Director of the Institute for Advanced Study in Warsaw interviews Adam Michnik, one of the intellectual architects of Solidarity and of the transition from communism in Central Europe, on Europe's illiberal turn.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.
