Happy to contribute if you want to go down that path! There's a couple of interesting regimes with similar quick extensions. Happy to jot a few things down.

This is cool Will! Thinking out loud... if an organism reproduces by fragmentation, the cost of soma remain quite high? Say an organism splits into k fragments of size N/k. Then the scaling rule becomes ln(p_g)/ln(k), not ln(p_g)/ln(N). Should be testable in the same way?

Excited to announce Eco-Onco Exchange — a virtual seminar series bridging mathematical ecology and oncology.
Each session pairs two speakers from each field around a shared theme, followed by joint discussion.
First three sessions coming soon! Register here docs.google.com/forms/d/e/1F...

The ecology of horizontal gene transfer Horizontal gene transfer (HGT) generates genetic variation in populations across all domains of life; however, most studies focus on individual transf…

I have a new review out in TiG titled, “The ecology of horizontal gene transfer”! I’ve been thinking about these ideas for years and this field is growing so fast it’s becoming impossible to review it. I hope this paper sparks discussion on different ways we can look at DNA transfer!

New preprint: evolution of cross-resistance between two cancer drugs inferred from lineage barcoding data from single drug exposures. Removes need for complex combinatorial exposure experiments. Another tour de force from brilliant Freddie Whiting @icr.ac.uk www.biorxiv.org/content/10.6...

I would be very happy to chat with prospective postdocs that have interest in quantitative biology as it applies to understanding the fundamental evolutionary and ecological processes that drive the acquisition and maintenance of resistance in microbes and cancer.

I'm constantly trying (/failing) to get this point across.

If you're a trained expert in a field, then it may be worthwhile to question the scientific consensus of your peers.

If you're not, the scientific consensus is absolutely the best you can do and it's arbitrary foolishness to disregard it.

I found this to be just as evident with reading. I spent some time having AI summarize new papers. I found it did a decent job! Only a month later I had retained none of the information of those papers. I had spent no time milling with the ideas, figures, or experiments. Useless.

Evolutionary Games: Mathematical Theory and Biological Insights

I am really happy to share that there will be a @nitmb.bsky.social workshop next year on mathematical and biological features of evolutionary game theory.

It was really fun to co-organize this workshop with Olivia Chu, Alex McAvoy, and @jplotkin.bsky.social.

1/27 We have a new paper out! Turns out that snowflake yeast have been hiding a secret from us - they've evolved a (very!) crude circulatory system. Not with blood vessels or a heart, but through spontaneous fluid flows powered by their metabolism. 🧪🔬

When the filter is removed (change to non-selective environment), a higher dimensionality of pleiotropic effects becomes apparent.

The study finds no evidence for this hypothesis, and instead supports the "pleiotropic shift" model.

My understanding is this is correct. In their pleiotropic expansion model, the mutations all have a broad inherent pleiotropy, but the selective environment acts as a filter, allowing only a low-dimensional subset to be relevant for fitness in that environment.

The idea would be a sphere is perfectly captured by the l=0 harmonic, while less spherical shapes will required increasingly higher order harmonics to accurately describe. Maybe more resolution/information than surface area vs volume, but less intuitive to interpret for readers.

10 months ago 2 0 1 0

This might be something that decomposing the shape into its spherical harmonics could do quite well.... It's kind of like how a Fourier transform breaks a complex signal down into sines and cosines, but it's breaking a 3D shape down into orthogonal shapes on a sphere.
