Non-diffusive slow heat dissipation induces high local temperature in living cells

Masaharu Takarada, Ryo Shirakashi, Masahiro Takinoue, Motohiko Ishida, Masamune Morita, Hiroyuki Noji, Kazuhito V. Tabata, Takashi Funatsu, Kohki Okabe

The paper investigates intracellular heat dissipation mechanisms and finds that non-diffusive heat dissipation causes slow temperature relaxation in living cells compared to homogeneous solutions.

Membrane dynamics-mediated heat retention dictates economical intracellular energy flow

Akira Murakami, T Sato, Haruya Suzuki, Takashi Funatsu, Kohki Okabe

This study experimentally demonstrates intracellular heat retention mediated by membrane dynamics, showing heat generated by metabolism is partially retained and used for efficient energy flow.
