It is surprising that #osmosis, a phenomenon so central to biology, has been cloaked in misunderstanding for so long. Jerry Manning & I show that the most plausible account for what drives water fluxes is one put forward by Peter Debye in 1923: https://bit.ly/3PbqRJ8

An exhibit about Emmy Noether has just opened in the library of the Institut Henri Poincaré in Paris

Picking up on this trace in 1968 Gerald (Jerry) Manning (Rutgers Univ) extended the Debye model to steady water fluxes, but again this work fell on deaf ears.

After tracking down Debye's original paper I was very fortunate to be able to begin a collaboration with Jerry and I'm chuffed to release a preprint of our work

It's extraordinary that the physical basis of #osmosis, one of the most important forces in biology, has been and is still widely mischaracterized in textbooks. One hundred years ago Peter #Debye published a simple kinetic theory that accounts for osmosis.

It is remarkable that despite Debye's renown as a physicist his paper slipped into oblivion except for traces in a textbook.

I wrote a tribute to Chuck Stevens, an incredible scientist who passed away recently. I was fortunate to work with, and learn from, him over the years. I will deeply miss him. #biophysics #neuroscience

Getting under the hood of the #pump-leak mechanism including #cation-chloride cotransporters, with analytical mathematical expressions, & getting to the bottom of the pesky #Donnan effect. Wonderful collaborating with with Zahra Aminzare

Vale, Hans Magnus #Enzensberger

A.M.T (1912-1954) - from his collection Mausoleum

It's certain that he never read a newspaper; that he knitted his gloves himself; ... whenever he broke his stubborn silence at meals, he fell into shrill stuttering or a cackling laugh. His eyes were a radiant, inorganic blue, like stained glass.

Dear fellow scientists, I know it's been said many times before but please please make a Google Scholar page and make it public? It makes life so much easier when going through tens and tens of unknown names (like I'm doing right now to help select symposia for a conference): one can find your latest papers, your most cited papers, etc. And if you have some principled objection to Scholar or to their stock-market-style citation counter, I get it and that's fine, but at least do orcid.org?

What are your favourite classic papers (topic, style, substance, inspiration) that you revisit?
Mine are:
Simple mathematical models with very complicated dynamics https://www.nature.com/articles/261459a0
More is different https://www.science.org/doi/10.1126/science.177.4047.393
The catastrophe controversy https://link.springer.com/article/10.1007/BF03023037
Network thermodynamics https://www.nature.com/articles/234393a0
I’m looking for holiday reading.

How do the pros @Nature@twitter.com take a sad plot and make it better? Or even bombastic-fantastic?

They'll join us to talk about the process! On November 29th at the #BioVis meetup#5
@Jasiek_Kr@twitter.com and Nic Spencer will tell us more!
