Heart rate variability changes in adolescents following surgical correction of aortic coarctation: Persistent autonomic alterations

Physiological Reports, Volume 14, Issue 3, February 2026.
Abstract Heart rate variability (HRV) is a sensitive marker of autonomic regulation. This study examined adolescents in the long‐term postoperative period after early surgical correction of aortic coarctation (CoA) compared with age‐matched healthy peers. Seventy adolescents (35 CoA, 35 controls; 12–17 years) underwent 5‐min resting ECG and respiratory

Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic
