Editor's note

Happy Earth Day! Today scientists around the world are taking to the streets to respond to what many see as the Trump adminstration’s disdain for truth, evidence and facts.

Some think a March for Science is a terrible idea. Meanwhile, in Europe, science is still highly regarded, so demonstrations there are largely an act of solidarity anyway, writes Luc Soete. But European scientists could do one thing better: infuse current EU debates (including discussions about Brexit's economic impacts and France’s presidential election), with expert analysis. (Don't miss all our coverage on the French election, below.)

And for some disconcerting weekend reading, learn why so many Brazilians believe that “the only good criminal is a dead criminal”.
