Stress-induced epigenetic desilencing is a prevalent (yet puzzling) phenomenon across eukaryotes. Here I propose that it may improve specificity for silencing harmful elements. @prxlife.bsky.social journals.aps.org/prxlife/abst...

Learning Principle for the Adaptive Shaping of Epigenetic Memory Repertoires
Fluctuation-driven feedback allows eukaryotic gene silencing to selectively suppress harmful genetic elements, with aberrant transcription reinforcing silencing locally while modulating it globally.

We analyzed changes in physiology relative to menopause using two large scale studies that include millions of lab tests. Rather than align by age, we used statistical inference to align tests to final menstrual period. (1/2) arunamed.com/the-menopaus...

The Menopause Cliff: What a Million Women's Lab Tests Reveal
TLDR: A massive study of 300+ million lab tests from 1+ million women just proved what women have been saying for years: menopause isn't a gradual slope—it's a physiological cliff. Nearly e

Theory predicted two kinds of fibrosis, hot and cold. We show in vivo that hot and cold fibrosis describe heart failure, and heart attack, respectively, showing that they are very different disease states. @shovalmiyara.bsky.social @eldadtzahor.bsky.social

Another day, another funky gene regulatory network behaviour! In our latest paper, we show how the mushroom bifurcation can encode an ultra-long biochemical timer. Even more interestingly, extrinsic noise can be used to improve timing precision! 🤯 @mathsmaret.bsky.social @josepsardanyes.bsky.social

Zelensky is a wartime leader watching his people suffer and die under Russian attacks every day. To be lectured and lied to by Trump and Vance, as they defend the war criminal dictator committing these atrocities, is unimaginable agony. An everlasting shame for America.

The way you were taught quantum mechanics depends on when you were a student. In Nature Reviews Physics, physicist and historian David Kaiser charts how the emphasis of quantum education has oscillated between philosophy and practicality. go.nature.com/40MyjiG 🔒
Around the world, physicists and engineers followed suit, rapidly becoming absorbed into various military projects.

Happy to share this- we analyze the hierarchical organization of attractor landscapes in dense associative memories and how it can facilitate transitions between attractor states. We use this to explain the control of transitions between stem and differentiated identities. arxiv.org/abs/2412.11336

We analyze a generalization of Modern Hopfield networks that emerges naturally in the gene regulatory networks that control cellular identity. Here gene expression patterns correspond to stored memori...

New preprint: Ageing is tightly reflected in longitudinal evolution of DNA methylation marks. We show that ageing also leaves a stereotypic footprint in how DNA methylation is correlated in the genome: positions that are roughly 500bp apart become more correlated. www.biorxiv.org/content/10.1...

Building a capacity for making Turing patterns into bacteria. This is very cool. www.cell.com/cell-systems...

A three-node Turing gene circuit forms periodic spatial patterns in bacteria
Engineering Turing patterns has been one of the most challenging problems in synthetic biology because even tiny changes in the reaction parameters destroy patterning. Here, the authors construct a more robust three-node genetic circuit in E. coli to generate different kinds of reproducible spot and stripe patterns.
