About this episode
This week’s stories: Smartphone App Catches What Sleep Trackers Miss A 2026 trial found that suvorexant, a popular prescription sleep drug, improves sleep quality scores — but worsens morning alertness and cognitive function while improving afternoon and evening performance. The study used a smartphone app to pulse users throughout the day, revealing a split-time-of-day signal that traditional sleep scales miss entirely. Optimizing your sleep dashboard and optimizing your waking performance are not the same thing.

Instead, the bats maintain genome integrity through superior DNA repair and oxidative stress management driven by the metabolic demands of flight. Telomere length may be a symptom, not the cause — and the longevity industry has been measuring the wrong thing.

The mechanism is dual — soluble galactomannan fibers slow carbohydrate absorption while bioactive compounds improve insulin receptor sensitivity in muscle and liver. It's a cheap, food-grade, CGM-trackable lever that most people have never tried.
