The last words Sara Platt’s doctor said to her before her life-changing procedure now haunt her. ‘He told me he would get his knife ready,’ she recalls. ‘His exact words were: “I’ll sharpen it tonight.” I’ll never forget it.’
For what happened in theatre was indeed life-changing, just not in the way Sara had hoped. In fact, it is no exaggeration to say that she was butchered by him, if indeed he was a qualified surgeon.

Fewer supermassive black holes may undergo growth spurts than astronomers had suspected.
Every known large galaxy hosts a gargantuan black hole at its center. Some of those behemoths experience bursts of beefing up, during which time they blaze brightly. But recent observations from the James Webb Space Telescope turned up far fewer of these active black holes than expected, researchers report in a paper submitted August 22 at arXiv.org.
If confirmed, the finding raises questions about how some supermassive black
Ungefähr zur Zeit der Wahl 2016 wurde YouTube als Heimat der aufstrebenden Alt-Rechten und äußerst populärer Verschwörungstheoretiker bekannt. Die Google-eigene Website hatte mehr als eine Milliarde Nutzer und beherbergte charismatische Persönlichkeiten, die enge Beziehungen zu ihrem Publikum aufgebaut hatten, was sie möglicherweise zu einem mächtigen Vektor für politischen Einfluss machte. Zu dieser Zeit hatte Alex Jones‘ Kanal Infowars mehr als 2 Millionen Abonnenten. Und der Empfehlungsalgorithmus von YouTube, der den Großteil dessen ausmachte, was die Leute auf der Plattform sahen,
When artificial intelligence companies build online chatbots, like ChatGPT, Claude and Google Bard, they spend months adding guardrails that are supposed to prevent their systems from generating hate speech, disinformation and other toxic material.
Now there is a way to easily poke holes in those safety systems.
In a report released on Thursday, researchers at Carnegie Mellon University in Pittsburgh and the Center for A.I. Safety in San Francisco showed how anyone could circumvent A.I. safety measures and use any
Our galaxy’s heart is a gluttonous monster. Like the mythical Kammapa of the Sotho people of southern Africa, the Milky Way’s central, supermassive black hole has swallowed nearly everything around it, growing heftier and heftier the more it eats. And it’s not alone. Black holes weighing as much as thousands, millions or even billions of suns sit at the center of nearly all known massive galaxies.
For decades, scientists thought that was the only place they’d find such behemoths, because
MINNEAPOLIS — Don’t try to do a quantum experiment near a black hole — its mere presence ruins all quantum states in its vicinity, researchers say.
The finding comes from a thought experiment that pits the rules of quantum mechanics and black holes against each other, physicists reported April 17 at a meeting of the American Physical Society. Any quantum experiment done near a black hole could set up a paradox, the researchers find, in which the black hole reveals
It makes up most of the universe, yet hardly anything is known about the so-called Dark Energy that envelopes us.
The unusual ‘something’ – one of the great mysteries of cosmology – is believed to be an unknown force that is pushing things apart more strongly than gravity and causing the universe’s expansion to accelerate.
Now, scientists from Imperial College London believe they may finally have an explanation for the source of unknown energy — black holes.

WASHINGTON — Of all the “bitter disappointments” he had as president, Harry Truman once wrote, the “one that has troubled me most, in a personal way,” was the failure to enact a national program that would assure all Americans “a full measure of opportunity to achieve and enjoy good health.”
More than 75 years after Truman first proposed universal coverage, Democrats are still chasing his dream. If President Biden’s social policy bill becomes law, they will make major strides toward
