As AI continues to develop rapidly, chatbots are gaining the power to create and manipulate images, with Shutterstock and Adobe currently leading the way. Despite the obvious power of AI algorithms, the technology has a few pitfalls, one of which is the unauthorized manipulation of copyrighted artwork and images.

MIT CSAIL thinks it has the answer to this growing problem in the form of PhotoGuard, a new technique that alters select pixels in an image to disrupt AI’s ability to understand what the image is.

The altered pixels are known as “perturbations” and are invisible to the human eye but easily seen by AI bots as they scan the color and position of every pixel in an image. Any edits AI tries to make to a protected image will also apply to the fake pixels, resulting in an unrealistic or broken final image, thanks to PhotoGuard.

“The encoder attack makes the model think that the input image is some other image,” explained MIT student and lead author of the paper, Hadi Salman. “Whereas the diffusion attack forces the diffusion model to make edits towards some target image”. The technique sounds complex but could potentially stop malicious actors from reverse engineering protected images by adding minor edits to circumvent copyright.

“A collaborative approach involving model developers, social media platforms, and policymakers presents a robust defense against unauthorized image manipulation. Working on this pressing issue is of paramount importance today,” Salman said in a recent press release. “And while I am glad to contribute towards this solution, much work is needed to make this protection practical. Companies that develop these models need to invest in engineering robust immunizations against the possible threats posed by these AI tools”.

A Three-Clinic Network Bets Dubai Is Ready For Longevity Medicine

Longevium has enlisted nearly 100 clinicians and created an AI platform in a bid to sell biological-age tracking as a medicine, not a wellness service.

a three-clinic network bets dubai is ready for longevity medicine

Dubai has been busily creating the scaffolding for a longevity industry, including a dedicated regulatory authority and a health market deep enough to sustain it. Now the clinics are arriving.

Longevium, a longevity clinic network, has opened three locations across the city: a flagship at Triple Seven Mall on Jumeirah 3, and branches in Jumeirah Lake Towers and Jumeirah Village Circle. Together they house a multidisciplinary team of nearly 100 physicians and specialists offering what the company bills as “a measurable medical system for longevity”.

The pitch is that longevity medicine should look less like a wellness menu and more like continuous clinical care. Each patient’s biological age assessment, laboratory results, body composition, cardiovascular risk factors, metabolic markers, and lifestyle data feed into a single profile, with a proprietary AI platform helping physicians track progress and adjust protocols against the patient’s own biomarkers.

“Healthy aging must be approached clinically through diagnostics, biomarkers, physician supervision, longitudinal tracking, and protocols tailored to the individual,” said Dr. Ksenia Butova, Longevium’s founder and CEO. “Our goal is to help patients understand their health trajectory before disease develops, and then actively change that trajectory”.

The treatment list spans peptide-based protocols, exosome therapies, stem cell approaches, GLP-1 metabolic optimization, hormone balance programs, cardiovascular prevention, and regenerative aesthetics — a model built for the entrepreneurs, executives, and international patients the clinic says want measurable results rather than generic wellness. A signature offering, Longevity Day, compresses biomarker testing, ultrasound and vascular imaging, specialist consultations, IV therapy, and a personalized optimization roadmap into a single three-hour visit.

“Here, longevity, biotechnology, AI, prevention, and regenerative medicine are converging into a single ecosystem,” said Butova. “This is why Longevium was built in Dubai, and why we believe the UAE can become a global reference point for longevity medicine”.

The emirate established the Dubai Longevity Authority in 2026 to oversee its longevity, wellness, and advanced health sectors, and the Dubai Health Authority reported insured beneficiaries exceeding 4.9 million in 2025, up around 6.5%, with insurance claims reaching approximately 49.6 million, up around 13.5%.
