What to know about Cellular Thermodynamics

Researchers from the University of Tokyo have discovered that living cells dissipate heat more slowly than artificial fluid-filled sacs, contradicting standard fluid physics. The study suggests that this 'nonspreading heat' may act as an active signal to power cellular functions and could lead to new medical treatments.

What happened

Cells trap heat in ways standard fluid physics cannot explain, study finds Stephanie Baum Scientific Editor Robert Egan Associate Editor Living cells cool much slower than our current understanding of heat conduction can explain, according to new research…

Why it matters

Researchers have used two techniques—high-speed temperature mapping and artificial heating—to observe how heat dissipates from living cells and similar-sized artificial, fluid-filled sacs (liposomes).

Common ground

While heat dispersed quickly from the artificial liposomes as expected, cells cooled significantly more slowly due to other biomolecules within the cell.
