It's weirdly difficult to remember that Trump's popular vote margin was /less/ than Hillary's in 2016. Biden got more votes in 2020 than Trump got in 2024 and Trump surrogates all under-performed in congressional races. This is not a mandate, I don't get why it is being portrayed that way.

With all the bullshit coming soon, letting rodents predict the weather is going to seem data-driven in comparison.

Preprint finally out! I show that eco-evo feedback can drive a tipping point where genetic drift overwhelms adaptation. This can result in a contraction of a species' range border or range fragmentation. Fragmentation is abrupt and arises readily under rapid temporal change. doi.org/10.1101/2025...

It feels surreal to see my PhD research featured on the cover of Science www.science.org/doi/10.1126/.... Incredibly proud of the work that went into this. And so grateful for the opportunities, resources, support and mentorship from co-authors and my whole scientific community that made it possible
Pollination in walnuts (such as this Persian walnut, Juglans regia) and pecans occurs through a genetically controlled temporal flowering dimorphism. Two distinct morphs alternate their phases of male and female flowering across the season, promoting outcrossing that has maintained a stable equilibrium throughout tens of millions of years of evolution. See eado5578.

A workflow for Tidyverse-based local synteny visualization: Good for visualizing local synteny across species, genotypes, or acorss regions of a genome. Can be used to showcase copy number variation. Still need to write the tutorial, but will be on my GitHub soon. #Genomics #DataVisualization
Local synteny visualization of 3 species and 4 homologous groups. Local synteny visualization of 5 accessions of beans, highlighting an array of TIR-NBS-LRR genes in this region.

Great to work with @ekopania.bsky.social, @jeffreygood.bsky.social, and everyone else on this project! I was happy to be able to present Emily's cool figure showing dN/dS of genes in different tissues and different time-points at Evolution a couple years ago:
A color figure (3) from the paper linked in the quoted post. The top panel A shows a drawing of the male rodent reproductive tract with different tissues shaded different colors, from dark blue to red, indicating median dN/dS values for genes expressed in those tissues. Below are colored cells using the same color scale from five different stages of spermatogenesis. Panels B and C below are graphs with points on the x-axise corresponding to the four cell stages shown above, with the y-axis for panel B being the proportion of genes under positive selection for each time point and for panel C being the proportion of genes expressed during that stage that are testis-specific. The points in panel B hover around the genome-wide average shown with a dotted horizontal line, while the points in panel C increase steadily above the genome-wide average, peaking in stage 4 (spermatids).
