What alopecia areata is, why dermatologists quantify hair loss with the SALT score instead of eyeballing it, how the four scalp regions are weighted, and what an S0–S5 grade does and does not tell you.
Why a normal blood oxygen level can still hide a lung problem, how the alveolar gas equation separates the lung from everything else, and why the expected gradient rises with age.
The six-day fertile window, the two day-specific probabilities that are genuinely published, why the days in between are deliberately left blank, and the trap of confusing an annual failure rate with the risk from one encounter.
What PREVENT is, the American Heart Association equation that replaces the Pooled Cohort Equations: it drops race, adds kidney function and weight, predicts 10- and 30-year risk, and for the first time includes heart failure.
The Body Roundness Index (BRI) estimates central body fat from your height and waist circumference, modeling the body as an ellipse instead of BMI's simple weight-for-height ratio. Learn how BRI is calculated, how to read the bands, what the landmark mortality research found, and where the score falls short.
GLP-1 receptor agonists such as semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) have reshaped obesity treatment. Learn how they work, exactly what the landmark trials found, how to read a weight-loss projection responsibly, and why these are prescription-only medicines.
What ADHD in children really is, its three presentations, how it is properly diagnosed, and how the NICHQ Vanderbilt scale used in our test works.
Bryan Johnson and the longevity crowd have turned a spotlight on artificial grass. Here's the honest, evidence-based picture of what synthetic turf releases — PFAS, microplastics, tyre rubber — and how those compounds relate to inflammation and immune health.
In atrial fibrillation, the same blood thinner that prevents a stroke can also cause a bleed. Two scores — CHA₂DS₂-VASc and HAS-BLED — put both sides of that decision into numbers.
Predictive formulas estimate your calorie needs from height, weight and age. Indirect calorimetry measures them directly from the air you breathe — and the difference can be large.
HOMA-IR takes two fasting numbers — glucose and insulin — and gives you an estimate of your insulin resistance that mirrors the gold-standard clamp test. Here is what it measures, what your number means, and where it stops working.
Insulin resistance is one of the few metabolic disorders that responds dramatically — and quickly — to lifestyle intervention. Here are the five evidence-backed levers, ranked by effect size, with the PubMed receipts.
