AI 'Speech Clock' Links Vocal Patterns to Biological Aging and Dementia Risk
A new AI tool called a 'speech clock' can estimate a person's biological age and dementia risk by analyzing voice recordings. Published in Science Advances, the study found that discrepancies between chronological age and 'speech age' correlate with brain atrophy, DNA methylation, and Alzheimer's biomarkers. Researchers suggest this low-cost method could eventually replace expensive medical tests for monitoring cognitive decline.

Study Links Early Smartphone Access to Higher Eating Disorder Rates in Teens
A new study published in JAMA Network Open finds that US children who own smartphones by age 12 are significantly more likely to develop eating disorder symptoms by age 14. The research, led by Dr. Jason Nagata of the University of California, San Francisco, analyzed data from the Adolescent Brain Cognitive Development Study. It highlights that early device access exposes preteens to appearance-focused content, which correlates with increased body dissatisfaction and disordered eating behaviors. Experts suggest delaying smartphone ownership by six months to a year may mitigate these risks.
AI in Oncology: From Hype to Curated Clinical Tools Amid a Data Tsunami
Artificial intelligence is increasingly used in cancer care, but its impact varies from promising detection tools to curated clinical decision support. While big tech promises cures, practical applications focus on managing information overload, with tools like Onqo Health's Easy Oncology gaining traction among oncologists. AI excels in pattern recognition but faces risks of bias and overreliance, necessitating human oversight.
Kate Tolo’s Extreme Biohacking Regimen Aims to Revolutionize Endometriosis Diagnosis
Kate Tolo, girlfriend of tech billionaire Bryan Johnson, is undergoing an intense, $2.6 million-funded health protocol to develop non-invasive diagnostic methods for endometriosis. While Johnson frames the effort as a labor of love, medical experts remain skeptical of the single-subject data, and Tolo has faced physical strain and public scrutiny for her extreme testing methods.
Neuralink's Dual Goals: Medical Aid or AI Warfare?
Neuralink, led by Elon Musk, is at a crossroads between developing technology to help people with disabilities and pursuing broader ambitions like AI integration and potential future AI conflicts, with recent leadership moves fueling questions about its true priorities.
Video Games Promote Brain Health Across All Ages
Recent research indicates that moderate, structured gaming can enhance cognitive functions such as attention, multitasking, and learning, with benefits most notable during short, varied sessions.
