First up: a spot of science-y April Foolery: Physicists Warming Up the LHC Accidentally Create a Rainbow Universe. Related: CERN researchers confirm existence of the Force (the photos alone are hilarious). Also: Smithsonian displays Wonder Woman’s invisible jet for April Fools’ Day. Bonus: Six of Ben Franklin's Greatest Hoaxes and Pranks. A bit of foolish history: When Your Co-Author Is a Monstrous Ass, or when the stronzo hits the fan. More foolery: Math Professor Pulls Off the Nerdiest April Fools' Joke Ever. Finally: Ah, those kooky kids and their April Fool's physics papers.

Not everyone is a fan of such frivolities: Lee Billings at Scientific American made a strong argument against April Fools’ in Science Journalism: "perhaps it’s past time for reputable science publications to abandon the practice—or at least to quietly discourage it. What seems like harmless fun among journalists and their more-savvy readers may have negative unintended consequences outside those knowledgeable inner circles."

Could black holes ever destroy the universe? Before you say no way, hear Sabine Hossenfelder out. "If the calculations in the new paper are correct, we could now conclude that no black holes can have previously completely evaporated anywhere in our universe, because otherwise we wouldn’t be here anymore. Since the distribution of primordial black hole masses is not known, however, some of them could be around and come into the final phase of evaporation any time, spelling the end of the world as we know it."

Mesmerizing Molten Glass Paintings by Etsuko Ichikawa. Per Spoon and Tomago: "Ichikawa removes fiery, molten glass from a kiln as it glows at 2100° F, and then manipulates it over thick paper, leaving scorch marks and burns. The process is something akin to photography, in which light is recorded on film, capturing and eternalizing the immediacy of a moment."

There was a of buzz this week over a provocative Op-Ed by Fareer Zakaria in the Washington Post: Why America’s obsession with STEM education is dangerous. Jen-Luc Piquant had some issues with it, and she was not alone: STEM Education Promotes Critical Thinking and Creativity: A Response to Fareed Zakaria. Chad Orzel countered by emphasizing that Science Is Essentially Human; Or Why Better STEM Education Isn't A Threat. "[T]he biggest problem I have with this whole line of argument is the way it sets science off as something alien, the classic example of which is the branding of arts and literature as 'the humanities,' as if other fields are inherently inhuman. STEM disciplines are implicitly set off as something that isn’t an intrinsic part of 'the human condition,' which Zakaria urges everyone to study. But, in fact, there are very few activities more essentially and intrinsically human than science."
