Study Links Common Cognitive Supplement L‑Tyrosine to Shorter Lifespan
Researchers analyzing data from over 250,000 UK Biobank participants found that genetically higher L‑tyrosine levels are associated with a reduced lifespan, particularly in men who lived about one year less on average. The Mendelian randomization approach isolated tyrosine’s effect, showing it to be more detrimental than its precursor phenylalanine.
Digital Heart Twins Can Guide a Lifesaving Procedure
Researchers at Johns Hopkins created patient‑specific digital heart twins that simulate electrical activity to plan ventricular tachycardia ablations. By converting high‑resolution MRI scans into 3‑D models, physicians could test virtual ablations and identify optimal targets before entering the operating room. In a pilot of ten patients, the approach trimmed procedure time from roughly three hours to thirty minutes and achieved lasting rhythm control. The study, published in the New England Journal of Medicine, suggests digital twins could improve outcomes for dangerous heart‑rhythm disorders.

Is Shaving Your Legs Really Worth It for Runners?
Shaving legs is a proven performance booster for cyclists, but its value for runners remains uncertain. Lionel Sanders’ wind‑tunnel tests showed a four‑minute Ironman improvement and a 13‑watt gain, yet running speeds generate far less aerodynamic benefit. The debate now...
An Exercise Physiologist Explains the Flawed Relationship Between VO2 Max and Bodyweight
VO2 max remains the benchmark for aerobic fitness, but the common relative calculation—dividing absolute oxygen uptake by total bodyweight—fails to account for body composition. Research from 2015 and a 2021 review shows VO2 max aligns more closely with lean muscle mass than...
Deep Aging Processes Can Be Slowed with Simple Habits
Facial aging is not a surface-level process. It reflects progressive changes in bone structure, fat compartments, collagen architecture, UV exposure, and hormonal signaling over time. The important point is that many of these pathways are modifiable. Daily photoprotection, resistance training, adequate...
