By incorporating hormone (steroid) metabolism pathways into an AI-driven model, they have developed a new system to estimate a person’s biological age, a measure of how well their body has aged, rather than just counting the years since birth.
Using just five drops of blood, this new method analyzes 22 key steroids and their interactions to provide a more precise health assessment. The team’s breakthrough study, published in Science Advances, offers a potential step forward in personalized health management, allowing for earlier detection...
