I have just posted a matters arising critique of

S.A. Shelby et al. Nature Chemical Biology www.nature.com/articles/s41...

on Zenodo:

Kervin, T. A. (2025). No phases? No phase separation. Zenodo. doi.org/10.5281/zeno...

Shelby and Veatch's data do not support their model.

Membrane phase separation drives responsive assembly of receptor signaling domains - Nature Chemical Biology
Super-resolution imaging detects plasma membrane domains that emerge when receptors are clustered in live B cells. Domain structures arise due to the membrane phase transition and can tune local membrane organization and receptor activation.

Dear pseudoscientists,

Be afraid. we have a new preprint debunking lipid rafts, detox theory, and the free energy principle in brain science:

1/ It is no secret that I view the unchecked rise of liquid–liquid phase separation (LLPS) in biology as a profound distortion of molecular biology. It conflicts with its principles, it is logically incompatible with them, and the claims made in its name have been, with rare exceptions,...

Dear #lipidtime
When you write "phase separation" in a non-equilibrium context, what do you mean? If you have one, please direct me to the definition you are using.
