From a single blood sample, new proteomic tools can now measure thousands of proteins at once. Dr. Tony Wyss-Coray’s lab is using that flood of data, together with machine learning, to build a much higher-resolution picture of what’s happening throughout the body and where someone’s health may be headed.The early signals are striking. In one analysis of people who appeared healthy by conventional measures, every additional 4.1 years of estimated heart age was associated with nearly 2.5 times the risk of heart failure over the following 15 years. Wyss-Coray sees this kind of measurement eventually becoming a “health compass”: something that could show which parts of the body are changing fastest, then help track whether an intervention is actually moving them in the right direction.Free course: Improve your metabolic healthGet our free email course on how glucose, nutrition, exercise, sleep, and measurement can help you build habits that support better energy and long-term health: ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://levels.link/wnl⁠What We Cover:How a drop of blood can now reveal information from thousands of proteinsWhy aging appears to happen in waves rather than at a steady rateWhy one part of the body may age faster than the restWhat young-blood experiments in mice taught Wyss-Coray about proteins and brain agingHow the work is moving from whole organs down to individual cell typesWhy the field’s biggest constraint may now be data collection rather than better AI🎙️ About the Guest:Dr. Tony Wyss-Coray is the D.H.
