Graças a um estudo inovador russo, dois nematoides muito antigos estão se movendo e comendo novamente pela primeira vez desde o Pleistoceno, revividos em placas de Petri depois de ficarem congelados no permafrost da Sibéria por milhares de anos

Time

A new technique for quantum computing could bust open our whole model of how time moves in the universe.

A new paper, published July 18 in the journal Physical Review X, opens the door to the possibility that that arrow is an artifact of classical-style computation — something that's only appeared to us to be the case because of our limited tools. [Read more about time.]

• Hoje, 510 milhões de europeus vivem na União Europeia, 1,3 bilhão de africanos estão de olho nela. Se os africanos seguirem o exemplo de outras partes do mundo em desenvolvimento como os mexicanos nos EUA, "em trinta anos... a Europa terá entre 150 e 200 milhões de afro-europeus, em comparação com os 9 milhões de hoje". Smith chamou esse cenário "Euráfrica".

Walt Whitman on Democracy

Walt Whitman on Democracy and Optimism as a Mighty Form of Resistance

“I can conceive of no better service… than boldly exposing the weakness, liabilities and infinite corruptions of democracy.”

BY MARIA POPOVA

“Progress is never permanent, will always be threatened, must be redoubled, restated and reimagined if it is to survive,” Zadie Smith wrote in her spectacular essay on optimism and despair. The illusion of permanent progress inflicts a particularly damning strain of despair as we witness the disillusioning undoing of triumphs of democracy and justice generations in the making — despair preventable only by taking a wider view of history in order to remember that democracy advances in fits and starts, in leaps and backward steps, but advances nonetheless, on timelines exceeding any individual lifetime. Amid our current atmosphere of presentism bias and extreme narrowing of perspective, it is not merely difficult but downright countercultural to resist the ahistorical panic by taking such a telescopic view — lucid optimism that may be our most unassailable form of resistance to the corruptions and malfunctions of democracy.
