For many artists, it's a precarious time to post art online. AI image generators keep getting better at cheaply replicating a wider range of unique styles, and basically every popular platform is rushing to update user terms to seize permissions to scrape as much data as possible for AI training.

Defenses against AI training exist—like Glaze, a tool that adds a small amount of imperceptible-to-humans noise to images to stop image generators from copying artists' styles. But they don't provide a permanent solution at a time when tech companies appear determined to chase profits by building ever-more-sophisticated AI models that increasingly threaten to dilute artists' brands and replace them in the market.

In one high-profile example just last month, the estate of Ansel Adams condemned Adobe for selling AI images stealing the famous photographer's style, Smithsonian reported. Adobe quickly responded and removed the AI copycats. But it's not just famous artists who risk being ripped off, and lesser-known artists may struggle to prove AI models are referencing their works. In this largely lawless world, every image uploaded risks contributing to an artist's downfall, potentially watering down demand for their own work each time they promote new pieces online.

Supermassive black holes are ravenous. Clumps of dust and gas are prone to being disrupted by the turbulence and radiation when they are pulled too close. So why are some of them orbiting on the edge of the Milky Way’s own supermassive monster, Sgr A*? Maybe these mystery blobs are hiding something.

After analyzing observations of the dusty objects, an international team of researchers, led by astrophysicist Florian Peißker of the University of Cologne, have identified these clumps as potentially harboring young stellar objects (YSOs) shrouded by a haze of gas and dust. Even stranger is that these infant stars are younger than an unusually young and bright cluster of stars that are already known to orbit Sgr A*, known as the S-stars.

Finding both of these groups orbiting so close is unusual because stars that orbit supermassive black holes are expected to be dim and much more ancient. Peißker and his colleagues “discard the en vogue idea to classify [these] objects as coreless clouds in the high energetic radiation field of the supermassive black hole Sgr A*,” as they said in a study recently published in Astronomy & Astrophysics.

If you were to envision the kind of accident that would cause a person’s bowels to explode out of their body, you might imagine some sort of gruesome stabbing or grisly car accident. You’d probably never imagine that something as commonplace and harmless as a sneeze would cause this kind of ghastly injury—but that’s exactly what happened to a Florida man earlier this month.

The man had recently had abdominal surgery and was suffering from wound dehiscence—where his surgical scar wasn’t healing properly. While eating breakfast, the man first sneezed, then began coughing. He noticed pain and a wet sensation on his lower abdomen—only to discover several loops of his bowel had burst through his unhealed wound.

The man was rushed to hospital for emergency surgery where his bowels were returned to his abdomen.
