**Osaka, Japan** – Scientists at Osaka University have developed a groundbreaking AI model capable of estimating a person’s biological age using just five drops of blood. This new method, detailed in *Science Advances*, analyzes the interplay of 22 key steroid hormones to provide a more accurate assessment of health than chronological age alone.
The AI, a deep neural network, considers the complex interactions between these steroids, offering a personalized view of aging. The researchers found a particularly strong correlation between cortisol levels and biological age, with a doubling of cortisol resulting in a 1.5 times increase in estimated biological age. This highlights the significant impact of chronic stress on the aging process at a biochemical level.
Lead researcher Dr. Qiuyi Wang explained the rationale: “Our bodies rely on hormones to maintain homeostasis, so we thought, why not use these as key indicators of aging?”
Professor Toshifumi Takao, an expert in analytical chemistry and mass spectrometry, emphasized the significance of the findings: “Stress is often discussed in general terms, but our findings provide concrete evidence that it has a measurable impact on biological aging.”
This AI-powered tool has the potential to revolutionize personalized health management. Future applications could include early disease detection, tailored wellness programs, and lifestyle recommendations designed to slow down the aging process. The researchers believe this technology could lead to earlier interventions and improved health outcomes.
