Kdy zvítězíme nad rakovinou?

Před třiceti lety vyhlásil americký prezident válku rakovině. Letos jen ve Spojených státech prohraje svou bitvu s touto zákeřnou chorobou denně na 1 500 mužů, žen a dětí. Kdy tato válka skončí?

Já věřím, že u mnoha druhů rakovin skončí brzy. Díky poznatkům základního výzkumu disponujeme pro boj s rakovinou novými prostředky, jež nabízejí rychlejsí diagnózu a účinnějsí léčbu. Na jejich základě vznikají nové léky, které se zaměřují na molekulární změny rakovinových buněk, díky čemuž lze předpovědět, kdo je rakovinou ohrožen geneticky nebo v důsledku působení faktorů prostředí. Tento pokrok zachrání mnoho životů.

Rakovina postihuje v lidském těle mnoho různých orgánů a tkání. Formy rakoviny se sice značně lisí co do výskytu a chování, mají vsak společnou příčinu: poskození genů. Geny jsou chemické kódovací jednotky, jež určují strukturu a funkci naseho těla. Vsechny buňky v lidském těle mají stejný počet genů, po polovině od každého z rodičů. Od sebe se pak buňky lisí různou kombinací aktivních genů.

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.

    Two Myths About Automation

    While many people believe that technological progress and job destruction are accelerating dramatically, there is no evidence of either trend. In reality, total factor productivity, the best summary measure of the pace of technical change, has been stagnating since 2005 in the US and across the advanced-country world.

But no such plan exists, only a taxpayer-funded propaganda campaign to help a corrupt administration deflect attention from its failure to fulfill Hungarians’ aspirations.
