Des robots dans le cerveau

CALGARY – La mise au point en 1926 par Harvey Cushing et William Bovie de l’électrocautère (qui permet de cautériser un vaisseau sanguin ou de pratiquer une incision grâce à un courant à haute fréquence) est une innovation qui a révolutionné la neurochirurgie. Compte tenu de la précision nécessaire pour opérer un organe aussi délicat que le cerveau, cette convergence des technologies mécaniques avec l’art de la chirurgie a permis de grandes avancées dans ce domaine.

Les progrès de la neurochirurgie se veulent toujours minimalistes. Comme dans tous les autres domaines de la chirurgie, moins la procédure interfère avec le corps, moins le risque d’effets négatifs sur la qualité de vie du patient est grand, lui permettant ainsi de récupérer une activité normale plus rapidement.

Cet impératif est d’autant plus prononcé lorsqu’il s’agit de procédures neurologiques sensibles. Des tâches comme de manœuvrer autour de petits vaisseaux sanguins d’un à deux millimètres de diamètre ou de retirer une tumeur cervicale sans endommager les tissus périphériques exigent des technologies comme le microscope opératoire et des outils multimodaux d’imagerie qui viennent soutenir et renforcer la compétence des chirurgiens.

    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.

    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.
