  • Tools for generating deep fake photographs are proliferating with greater ease of use and prominence in pop culture. Image authentication tools can defeat these deceitful developments by verifying that a digital image was actually produced by a physical camera. The challenge is that these tools must be robust to desirable image transformations.

    Camera attestation uses digital signatures to prove an image’s provenance from a camera. Lossy compression makes minute changes in order to reduce an image’s size, and blurring or redacting regions of an image can protect its subjects. These changes invalidate an image’s signature. Prior works use zero-knowledge (ZK) to prove a published image’s edit history, but they do not survive lossy encoding such as the JPEG format.

    We present \zkjpeg, a cryptographic tool for JPEG compression that proves an image was correctly compressed from a secret, committed input. In addition, our tool can verify a large family of image transformations by integrating them into JPEG compression with minimal cost.



  • The exchange escalated sharply when Watters pressed El-Sayed on gender-affirming care for minors. “Sex change for minors. Do you support that?” Watters asked. El-Sayed, a doctor and former public health official, responded, “I just think the government shouldn’t tell you what kind of healthcare you should have.” Watters pushed further, asking, “So you think it’s OK for a parent to slash his kid’s ding-a-ling off?” El-Sayed shot back, “Do you really want to have this conversation? Are you circumcised?”

    A visibly caught-off-guard Watters replied, “Yeah, but I mean that’s a personal question, doctor.” When Watters argued circumcision is “different than castration,” El-Sayed maintained his point.

    “I’m just saying that yes, circumcision is surgery on a kid’s ding-a-ling,” he said. By bringing up circumcision, El-Sayed was attempting to argue that society already accepts parental rights and medical decision-making regarding surgical procedures on a minor’s genitalia, and that the government should not single out specific healthcare choices. But his clunky comparison gave Watters an in.

    The host called the comparison “wacky,” telling El-Sayed, “Michigan’s not going for that. That is sick stuff.”

    The interview quickly drew a swarm of reactions from conservative media figures. YouTuber Benny Johnson wrote on X that El-Sayed had shocked Watters by “demanding to know if Fox News host is CIRCUMCISED live on-air,” adding, “I’ve never seen more of a nightmare interview.”

    Commentator Nick Sortor wrote, “Abdul El-Sayed says CIRCUMCISION is the same thing as SEX CHANGES FOR MINORS. These people are SICK.”

    Arkansas Gov. Sarah Huckabee Sanders, who served as White House press secretary during Donald Trump’s first term, said, “This is the radical left. This is who they are. Insane and sad."

    Commentator Clay Travis wrote, “Holy s–t, Abdul El-Sayed said circumcision is similar to sex change operations on minors.

    ”Former White House deputy press secretary Abigail Jackson piled on as well, writing that El-Sayed was “2 for 2 on comparisons that make him look like an absolute insane person.”

    Conservative strategist Mike Davis was blunter still.“Goodbye, Abdul,” he wrote. “You just guaranteed your defeat. Dingaling.”


  • But the initial success of the X1 demonstrator does not mean Heart Aerospace is planning to commercialize an all-electric aircraft. Current battery-electric systems can only typically sustain short flights of about 100 to 200 miles, which is why they have been limited to air taxi operations by companies such as Joby and Archer.

    Instead, testing of the X1 and a planned follow-on X2 aircraft will shape development of Heart Aerospace’s main offering to the airline industry—a 30-seat hybrid-electric regional airliner known as the ES-30.

    That planned production aircraft for commercial flights would combine two inboard electric motors with commercial turboprop engines that run on jet fuel, enabling 125 miles of all-electric flight and 500 miles of flight range when operating in hybrid mode.

    Having the extended 500-mile range would enable the ES-30 hybrid-electric airliner to operate in popular short-haul corridors that connect major US and European cities. United Airlines has committed to eventually purchasing 100 aircraft from Heart Aerospace, with other major airline customers also having signed letters of intent, according to Flying magazine.
