AI Chatbots Drive Mental Health Concerns as Teens Show Addiction Patterns and Health Anxiety Spirals

More than 987 million people globally now use generative AI chatbots, including 64% of American teens. Recent studies reveal troubling patterns of behavioral addiction, health anxiety spirals, and over-reliance on AI companion chatbots like ChatGPT, Character.AI, and Replika. Researchers warn that what starts as emotional support often evolves into dependency that disrupts sleep, academics, and real-world relationships.

Oxford AI tool predicts heart failure risk five years early by detecting invisible heart fat

Scientists at the University of Oxford developed an AI tool that predicts heart failure risk up to 5 years in advance with 86% accuracy. The technology analyzes routine cardiac CT scans to detect subtle changes in fat around the heart linked to inflammation—changes invisible to clinicians using standard imaging techniques. High-risk patients were 20 times more likely to develop heart failure than those at lowest risk.

Deepfake X-rays fool radiologists 75% of the time, raising alarm over medical fraud and cybersecurity

A new study published in Radiology reveals that radiologists can correctly distinguish real from AI-generated medical X-rays only 75% of the time, even when aware synthetic images are present. The research, involving 17 radiologists from six countries, found that 41% initially suspected deepfake infiltration. Large language models like ChatGPT and Gemini performed similarly poorly, achieving 57-85% accuracy, highlighting urgent concerns about fraudulent litigation, hospital cybersecurity, and research integrity.

ChatGPT didn't cure dog cancer, but AI tools helped researchers develop personalized treatment

Australian tech entrepreneur Paul Conyngham used ChatGPT and other AI tools to help create what may be the first bespoke cancer vaccine for a dog. His Staffordshire bull terrier mix Rosie showed tumor shrinkage after receiving the personalized mRNA vaccine. But experts warn the viral story oversimplifies AI's role—human researchers designed and manufactured the treatment, while chatbots primarily assisted with literature searches and data interpretation.
