The January wildfires left many scars on the city of Los Angeles, from rubble-reduced homes to torched abandoned vehicles. Though cleanup crews quickly cleared much of the debris, one alarming invisible impact lingered over the city for months, a new study suggests. In late March—more than two months after the flames died out—researchers detected levels of carcinogenic hexavalent chromium (a.k.a. chromium-6) 200 times greater than baseline levels for LA air. If this pollutant sounds familiar, you’re probably thinking of the 2000 film Erin Brockovich, a dramatization of a true story about hexavalent chromium water contamination. Though the levels the researchers…

Two of the staffers have returned to OpenAI, where they both previously worked, after less than one-month stints at Meta, WIRED has confirmed.Avi Verma was previously a researcher at OpenAI. Ethan Knight worked at the ChatGPT maker earlier in his career but joined Meta from Elon Musk’s xAI.

A Multimodal Radiology Breakthrough Introduction Recent advances in medical AI have underscored that breakthroughs hinge not solely on model sophistication, but fundamentally on the quality and richness of the underlying data. This case study spotlights a pioneering collaboration among Centaur.ai, Microsoft Research, and the University of Alicante, culminating in PadChest‑GR—the first multimodal, bilingual, sentence‑level dataset for grounded radiology reporting. By aligning structured clinical text with annotated chest‑X‑ray imagery, PadChest‑GR empowers models to justify each diagnostic claim with a visually interpretable reference—an innovation that marks a critical leap in AI transparency and trustworthiness. The Challenge: Moving Beyond Image Classification Historically, medical…

Last month, KrebsOnSecurity tracked the sudden emergence of hundreds of polished online gaming and wagering websites that lure people with free credits and eventually abscond with any cryptocurrency funds deposited by players. We’ve since learned that these scam gambling sites have proliferated thanks to a new Russian affiliate program called “Gambler Panel” that bills itself as a “soulless project that is made for profit.” A machine-translated version of Gambler Panel’s affiliate website. The scam begins with deceptive ads posted on social media that claim the wagering sites are working in partnership with popular athletes or social media personalities. The ads…

Universal Pictures Do you remember the days when “Star Wars” movies used to be good? Not “Star Wars” in general — the movies. “Andor” season 2 has barely stopped tugging our heartstrings with its grounded rebel stories, the well-received “Star Wars Jedi: Survivor” video game was released in 2023, and Marvel is dropping sweet (and often Darth Vader-themed) comics all the time. “Star Wars” as a franchise is doing just fine. The movies, on the other hand, could use a win.  It’s been close to a decade since the franchise rolled out a truly worthwhile big-screen effort —…

Sir Jim Ratcliffe has sold luxury motorcycle jacket brand Belstaff to sportswear label Castore, in a further sign of the billionaire scaling back his Ineos empire outside its core chemicals business. The deal, announced on Thursday, will see Castore acquire the heritage fashion house for an undisclosed sum, while Ineos will take a minority stake in the fast-growing sportswear company, which supplies kit for England’s cricket and rugby teams. Ashley Reed, Belstaff’s chairman, described the transaction as “a union of two British brands that have come together through shared qualities of purpose-led design and entrepreneurial spirit.” Ratcliffe, 72, bought Belstaff…
