Os Reaccionários da Modificação Genética

PALO ALTO – As pessoas em todo o mundo estão cada vez mais vulneráveis ​​ao uso daquilo a que o químico vencedor do Prémio Nobel, Irving Langmuir, denominou "ciência patológica" - a "ciência das coisas que não o são" - para justificar a regulamentação governamental ou outras políticas. É uma especialidade de grupos autodesignados de interesse público, cujo objectivo, muitas vezes, não se traduz na protecção da saúde pública ou do ambiente, mas sim numa oposição à investigação, produtos ou tecnologia de que não gostam.

Por exemplo, as técnicas modernas de engenharia genética - também conhecidas como biotecnologia, tecnologia de ADN recombinante, ou a modificação genética (GM) - fornecem as ferramentas que permitem que plantas velhas façam coisas novas espectaculares. No entanto, estas ferramentas são constantemente mal apresentadas ao público.

Mais de 17 milhões de agricultores em cerca de três dezenas de países em todo o mundo utilizam culturas geneticamente modificadas para produzir maiores rendimentos com menos recursos e com menor impacto ambiental. A maioria dessas novas variedades são concebidas para resistir aos ataques de pragas e doenças, de modo a que os agricultores possam adoptar práticas de plantio directo mais ecológicas e utilizar herbicidas menos nocivos.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  2. The Great US Tax Debate

    ROBERT J. BARRO vs. JASON FURMAN & LAWRENCE H. SUMMERS on the impact of the GOP tax  overhaul.

    • Congressional Republicans are finalizing a tax-reform package that will reshape the business environment by lowering the corporate-tax rate and overhauling deductions. 

    • But will the plan's far-reaching changes provide the boost to investment and growth that its backers promise?

  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

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. 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.
