At least mathematical biology is too basic for them to bother with
The OpenAI Research Catalog contains 722 manuscripts arranged under 17 mathematical subjects, excluding mathematical biology.

Figure 3 makes it plain
Respondents were asked to indicate the degree and direction of the impact of federal and state policies since January 20, 2025 on the categories of "Impact on my field of science", "Impact on my Department and Institution", "Impact on my research", "Impact on my career prospects", and "Impact on my personal life". A percentage of respondents reported positive impacts in each category (~1-2%). 79.7% of respondents said that federal policies since January 20, 2025 had "extremely negative impact" or "irreparable harm" on their field of science (Figure 3, top row), with a total of 96.8% of respondents saying the impacts have been negative. Over half of respondents said the effects on their department/institution were "extremely negative" or "irreparable harm" (54.8%), with a total of 91.9% responding that the impacts have been negative (Figure 3, second row). Most respondents reported "slightly negative" to "extremely negative" effects on their research (78.4%) and career prospects (70.9%), with about 15-22% reporting no impact and 5-6% reporting irreparable harm in both categories (Figure 3, third and forth rows). A majority of respondents reported slightly negative to extremely negative effects on their personal life (82.3%), with 5.3% reporting irreparable harm and 11.1% reporting no impact (Figure 3, fifth row).

Understandable given how thorough the post is! It's near the end.
"Another potential explanation for these impossible results is that the experiments actually were performed with a p16-INK4a specific antibody, but at the moment of writing the paper, a p16-ARC antibody code was retrieved from Abcam or Santa Cruz’s website and inserted into the methods section erroneously. This second explanation might seem more charitable in some sense, but I’m not sure it is… are we to believe that antibody codes in papers are selected at random by a lab tech based on the first search result? For papers to be meaningful the methods have to describe what was actually done and the results have to show what was observed."

Having just finished @adamjkucharski.bsky.social's "Proof", I found myself at last week's conference referencing the book wrt the ladder of causation; why RCTs aren't always best; communicating uncertainty; and what constitutes proof. Ended up telling everyone just to buy and read it themselves.

Lacking time for yesterday's post-conference excursion (which also sounded fantastic) I spent the afternoon at the Heraklion Archaeological Museum, which is packed with phenomenal, ridiculously ancient artworks, many inspired by the natural world. A great end to a great few days of science and fun.

Darwin knew it
"Thus, as I believe, the most wonderful of all known instincts, that of the hive-bee, can be explained by natural selection having taken advantage of numerous, successive, slight modifications of simpler instincts; natural selection having by slow degrees, more and more perfectly, led the bees to sweep equal spheres at a given distance from each other in a double layer, and to build up and excavate the wax along the planes of intersection. The bees, of course, no more knowing that they swept their spheres at one particular distance from each other, than they know what are the several angles of the hexagonal prisms and of the basal rhombic plates. The motive power of the process of natural selection having been economy of wax; that individual swarm which wasted least honey in the secretion of wax, having succeeded best, and having transmitted by inheritance its newly acquired economical instinct to new swarms, which in their turn will have had the best chance of succeeding in the struggle for existence."

I just returned the proof of our paper "Selective sweep probabilities in spatially expanding populations". Google's AI Overview is already reporting the main results (presumably scraped from the November 2023 preprint) as established fact.
Google's AI Overview says, "Selective sweep probabilities in spatially expanding populations, such as in growing tumours or biological invasions, are generally independent of the mutation rate and determined by the ratio of mutant-to-wildtype radial expansion speeds, with the probability approximated by \((1-c_{wt}/c_{m})^{d}\) (where \(d\) is the spatial dimension)." These are new results that we reported for the first time in our preprint.

All advice has been very sensible and conventional. It's helping me prioritise and avoid being overly ambitious. E.g. yesterday I ran a parkrun aiming to beat a target time and missed by a few seconds. ChatGPT put this in context of my more important marathon goal.

In 2017 I created the ggmuller R pacakge to draw "Muller plots" combining phylogeny and frequency dynamics. The latest version 0.7.0 fixes deprecated dependencies and includes a few other minor improvements. CRAN: cran.r-project.org/web/packages... Vignette: cran.r-project.org/web/packages...
A Muller plot generated by ggmuller. The horizontal axis is time, and shapes of different colours represent genotypes (or other subtypes), with height corresponding to genotype frequency (or relative abundance) at the corresponding time point. Descendant genotypes are shown emerging from inside their parents. In this example, colour represents relative fitness.

To our surprise, our tree balance index was able to predict disease-free survival in the TRACERx cohort, even after controlling for cancer stage. The index is especially useful for stratifying patients in stage 2. The association is robust to various changes of the data and the method. 4/n

Join @cmaley.bsky.social, @lucielaplane.bsky.social, Joel Brown and Benjamin Spada for a live EvoChat discussion about "How we define cancer matters", hosted by the International Society for Evolution, Ecology and Cancer (ISEEC). Oct 1st at 8am PST, 11am EST, 5pm CEST ucsb.zoom.us/j/8313111375...
Abstract: Current definitions of cancer describe what cancer does but not what it is. Furthermore, they derive largely from human cases and may not apply to other multicellular organisms, especially those lacking a basal membrane. Comparative oncology, however, has shown that cancer occurs across a broad diversity of organisms. What definition should be adopted when framing cancer in a comparative and evolutionary perspective? And can an evolution-based definition be applied in clinical oncology? We will show that a universal definition of cancer not only helps provide a basis for progress in comparative oncology, but can also help to explain the diversity of cancer phenomena within humans.

The first race I even won was the Semi des Vendanges, a half marathon on rocky trails north of Montpellier. I never thought I'd get a chance to run it again so was delighted to finish fourth today, having gone up two age categories. This being France, every finisher got a bottle of local wine.
No podium today but at least I got this pretty bottle of Cabernet Franc, Grenache and Syrah from a family-owned domaine in the small town of Teyran, which hosted today's trail race.
