Thermal Limits and Decline of Synechococcus Under Accelerated Warming and Marine Heatwaves

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Marine picophytoplankton, including Synechococcus, contribute ~20% of ocean primary production and are considered thermally resilient. However, 7 years of observations and experiments in the Red Sea show that recent extreme warming reduced Synechococcus abundance. Seawater temperatures during marine heatwaves in 2023–2024 exceeded the thermal limits of

Bachmann's Bundle‐Related Atrial Tachycardias Following Catheter Ablation of Persistent Atrial Fibrillation

open access: yesJournal of Cardiovascular Electrophysiology, Volume 37, Issue 3, Page 561-571, March 2026.
ABSTRACT Background Atrial tachycardias (AT) after radiofrequency ablation (RFA) of atrial fibrillation (AF) may utilize Bachmann's bundle (BB). Due to their epicardial location, these ATs remain poorly understood. Objective To describe the electrophysiologic and anatomic basis of BB‐related ATs.

Systolic‐dominant coronary flow in rats and mice: Challenging the diastolic paradigm across conscious and anaesthetized states

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 684-699, 1 March 2026.
Abstract Extensive research in humans, dogs, rabbits, rats, mice and other mammals has consistently demonstrated that coronary blood flow (CBF) peaks during ventricular diastole. For example, studies using transthoracic Doppler echocardiography in anaesthetized rats and mice, isolated blood‐perfused rat hearts and Doppler probes sutured to the ...
