Turns out biology tracks more than we thought — from a spit test that reads your all-nighter to a surgical outcome that still shows up in household chores two decades later. Plus: habits aren't built gradually. They snap.
Severe social jet lag among surgeons was associated with higher rates of major adverse events, independent of sleep duration, workload, and patient risk.
In a target-trial emulation of more than 600,000 veterans, GLP-1 RA initiators saw fewer new substance use disorders—and patients with existing SUDs had fewer overdoses, hospitalizations, and deaths.
A gene variant that raises GLP-1 levels somehow makes GLP-1 drugs work worse. Plus: why your nose might still recover two years out, and what urine might eventually tell us about schizophrenia.
