It is with great sadness that the University shares the news of the death of Professor Sir John Gurdon, founder of the @gurdoninstitute.bsky.social

🚨Job alert in theory/math devbio 🚨
I’m currently advertising postdoc positions to join my group. We’re building reaction-diffusion models to understand some of the crazy things embryos can do. We are based in a beautiful part of Scotland :). Please share! www.abdnjobs.co.uk/vacancy/rese...

I am thrilled and honored that—alongside my work as a researcher in industry—I have been appointed Adjunct Professor at @penningtonbiomed.bsky.social. I will be working with Dr Steven Heymsfield and Dr Peter Kotanko in the area of human body composition and metabolism.

New preprint: How do cells measure time? In human development, pluripotent epiblast cells pause for about two weeks before differentiating into more specialised cell types. We show that this timing is controlled by a transcriptional clock that works like an hourglass. www.biorxiv.org/content/10.1...
A transcriptional clock of the human pluripotency transition
Developmental timing differs strikingly between mammals. All embryonic and some placental lineages emerge from the pluripotent epiblast in a temporally defined sequence, lasting about two weeks in the...

Saddened to hear Bela Novak has died

Pioneering and influential systems/quant biologist. Changed how we think about the cell cycle (amongst other things).

New preprint: are deep neural networks just complicated curve fitters or can they show emergent behavior that is independent of the data? We show that training deep neural networks gives rise to emergent weight morphologies independent of the training data.

I'm always amazed by hallmarks of universality in social systems. This linked paper by Pal et al. shows how a minimal model of random voting behavior can reproduce margin distributions across many countries. They suggest that deviations from this universality might hint at electoral malpractices.
Universal Statistics of Competition in Democratic Elections
Elections for public offices in democratic nations are large-scale examples of collective decision-making. As a complex system with a multitude of interactions among agents, we can anticipate that uni...

Interspecies scaling laws (allometries) are a fascinating phenomenon. Here we investigate allometric scaling relationships of quantitative cardiomyocyte properties across different mammalian species.

If you run your own domain, you can change the handle of your Bluesky account to your domain name. This provides a bit of an identity verification. See here: bsky.social/about/blog/4...

Note that I am not an IT security expert and can't speak to any security issues that might arise from this.

Using a domain as your handle helps with account identity, verification, and portability. Here's how to set your domain as your handle.

Teaching statistical physics this term. If things get difficult, we get help from super heroes like Mr T (who can relate macroscopic variables) or S-man (who can derive them micrscopically). There is also a villain called Boltz-man who has the habit of creating super-large numbers.

In this collaboration with Ben Simons' and Shosei Yoshida's lab, we propose a minimal mechanism for the intricate spatiotemporal dynamics of the spermatogenic wave.

Congratulations to Toshiyuki Sato (experiment) and Yuting I. Li (theory) for their outstanding work!
