Hearts of hibernating mammals continue to beat at near 0°C thanks to continued excitability. Several members of a minor group of voltage-gated Na channels in the heart are found to contain a mutation unique to hibernators. From John S. Willis @universityofga.bsky.social: rupress.org/jgp/article/...
Takashi Tominaga and Yoko Tominaga develop a kinetic framework for the major membrane-current components in #Paramecium. The framework integrates late-component, leak, and inward Ca2⁺ currents, including Ca2⁺-dependent inactivation and slow recovery. rupress.org/jgp/article/...
