Really nice article laying out the semantics of sex/sexes that causes persistent confusion and arguing in our community. It lays out the undisputed patterns in biology and makes clear any "lack of consensus" on sex/sexes is arguing across different levels. academic.oup.com/icb/article/...

Evolution, Development, and the Incoherence of Sex: A Framework for Multiple Sex Concepts

Synopsis. The word sex can refer to at least seven distinct, evolutionarily related biological phenomena (0–6 below). Bacteria and archaea use mechanisms f

I'm excited that our paper (@chrisblanar.bsky.social +others), "Spatial Variation in Sex-biased Parasitism of an Androdioecious Mangrove Fish" is out now as part of the "Sex Across Origins" symposium!@sicb.bsky.social @aramaticasper.bsky.social @jjinsing.bsky.social academic.oup.com/icb/article/...

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNAS

On biopharma companies: "I would love to see the industry grow a spine here and raise its voice just a tiny bit. Am I expecting it to? Well, that’s another question entirely. But there’s still time to do the right thing."

Derek Lowe@dereklowe.bsky.social · 2mo ago

One prominent group has been totally silent about the Trump administration’s latest attempt to grab control of all federal science funding. That’s the biopharma companies, and their suddenly shy, quiet CEOs. Here’s the calculation they’re making:

Super excited about this new paper! and eternally grateful to the amazing coauthors, the wonderful network of colleagues who gave us stimuli, and all of the thousands of people that listened to animal sounds for us!

out now in Science: @loganjames.bsky.social collected pairs of sounds in 16 species where we *know* which sound is more attractive (to that species) he played them to ppl on themusiclab.org, asking, in each pair, which was nicer. humans agreed w other animals doi.org/10.1126/science.aea1202

Mehr5,7,8Many animals produce courtship sounds, and receivers prefersome sounds over others. Shared ancestry and convergentevolution may generate similarities in preference across speciesand underlie Darwin’s conjecture that some animals “havenearly the same taste for the beautiful as we have.” In this study,we show that humans share acoustic preferences with a rangeof animals, that the strength of human preferences correlateswith that in other animals, and that humans respond fasterwhen in agreement with animals. Furthermore, we foundgreatest agreement in preference for adorned, ancestral, andlower-frequency sounds. humans’ music listening experiencewas associated with preferences. These results are consistentwith theories arguing that biases in processing sculpt acousticpreferences, and they confirm Darwin’s century-old hunchabout the conservation of aesthetics in nature

Jacket design for Darwin and the Queer Origins of Life: A History of Sex and Science by Ross Brooks. It features a historic, drawn image of a gynandromorph gypsy moth, with distinctive female patterning on its left side and male on its right. Against a black background, the image and text (title and author's name) are brightly rendered in a spectrum of colours resonant of the Progress Pride Flag.

It’s happening!! #SICB2026 Tomorrow, from 8AM to 3:30PM come to C120/121/122 for ✨Sex Across Origins: Questioning animal-centric assumptions and developing integrative frameworks.✨ Also! 3 fantastic complimentary sessions Tuesday in B113, with a special focus on education in the morning.

I'm looking for PhD students to join the lab starting August 2026. We study the evolution of insect chemical signals so if you're interested in evolutionary biology, chemical ecology, molecular biology, behavior, or genetics, this could be a good fit for you! More info here: tinyurl.com/mrxchwfm
