A fun new paper with unexpected insights into composition-dependent phase separation phenomena in multicomponent mixtures - great work from Filipe Thewes!

New mechanism identified in complex mixtures by researchers at our Uni: unexpectedly, a molecule that is only slightly more common than the others in a mix can lead to it almost entirely separating out from the rest: uni-goettingen.de/en/3240.ht…, doi.org/10.1103/PhysRevLett.… #biophysics
Image by Filipe Thewes showing how a small composition imbalance has resulted in one component (yellow), which was just slightly more prevalent than the others, driving the phase separation in the mixture.

feinbaeckerei_thiele am Nonnenstieg in Göttingen hat schon länger geschlossen. Wenn Ihr dort auch gerne Brötchen, Kuchen etc gekauft habt, wendet Euch an Thiele auf Instagram, Facebook oder per Email an [email protected] um zu sagen, wie sehr uns die Filiale fehlt!
New aging physics in active glasses: local "stirring" by active forces can drive rather than interrupt aging.

Aging affects not just living beings. Materials, eg plastics and glasses, also age as their particles try to pack better. Physicists at our Uni used computer simulations to find out more in “living” glassy systems: ogy.de/dhke, doi.org/fjkp @PhysRevLett

Preprint update: how do precise boundaries of gene expression form in developing tissues? Lots of recent attention on noise in extracellular gradients & differentiation adhesion to correct mistakes But here we find the GRN can also suppress noise biorxiv.org/content/10.1101/…
Precision of Tissue Patterning is Controlled by Dynamical Properties of Gene Regulatory Networks

Precision of Tissue Patterning is Controlled by Dynamical Properties of Gene Regulatory Networks

During development, gene regulatory networks allocate cell fates by partitioning tissues into spatially organised domains of gene expression. How the sharp boundaries that delineate these gene...

Tractable nonlinear memory functions as a tool to capture and explain dynamical behaviors

Tractable nonlinear memory functions as a tool to capture and explain dynamical behaviors

The authors develop a method for dimensionality reduction of generic nonlinear dynamical systems using Zwanzig-Mori memory functions, and apply it to biological examples.

Even latex runs at snail's pace!
Yes, Thunderbird takes long time to load messages, openoffice slow to open/close files etc.

@KingsITsystems Very laggy on nmscde001150.nms.kcl.ac.uk today, slow loading of external/internal websites, also slow file server access. Why?
Cannot log in from thunderbird - via owa seemed to work but now fails, ref a78cdc6f-31fc-4568-a04c-dd36b8a5f829
@KingsITsystems Hi bastion.nms.kcl.ac.uk says connection on port 22 refused - any idea why? my id stty3189
@KingsITsystems All old messages from my inbox have disappeared in the last hour, only new ones arriving. Help! stty3189
@KingsITsystems Server issues? No email login via thunderbird or outlook web app; status page internal.kcl.ac.uk/it/suppor… does not load either.
