Thoughts on traveling by train to 2 international conferences a bit far:
Lausanne - Glasgow for #EED2026, 13h of train to, a bit more with a night train fro.
Lausanne - Copenhagen for #SMBE2026, 22h each way including a night train.

#NoFlyEED made it to London 🏴󠁧󠁢󠁥󠁮󠁧󠁿by sleeper train from Glasgow 🏴󠁧󠁢󠁳󠁣󠁴󠁿, next leg Paris 🇫🇷then Geneva 🇨🇭. 🤞Hope there won't be disruptions from the G7 to get home.
Thanks to all the organizers and speakers of #EED2026, a wonderful conference, a 1-week sabbatical 😄.

Khila: will experimental evolution select for longer legged males? Surprisingly, males selected for high competition have more variation in leg size than controls. #EED2026
Explanation: exagerated legs are negative for the females. Thus selection on females countracts selection on males.

Khila: if large long legged males have high success, why is their variation in the population? Survival cost of exagerated trait? No relation to resistance to starvation, other tests… no costs have been found so far. #EED2026

Khila: RNA-seq -> exagerated legs are enriched in sex-biased genes. BMP11 RNAi removes most of the exagerated legs. #EED2026
Closely related species M. pulchella without exagerated lengths: almost no fighting among males. BMP11 RNAi M. longipes stop fighting!

Khila is unique in how he goes from systematics in the field, to behavior observations and experiments, to uncovering the key developmental genes involved. Beauty of #EvoDevo #EED2026

Khila: the large legs are important for male-male fights to secure small floating objects for females to lay eggs. Long legged males fertilize more eggs, even more so when competition for floating objects is stronger. #EED2026

Khila #EED2026: high variabiity in size between males in waterstrider M. longipes. Example of exagerated sexually selected trait. Difference is so large that the big/long legged and small/short legged males were originally classified as distinct species. They live in small temporary rain puddles in the tropics.

Khila: strong phenotypic differences between males and females, due to sexual conflict: specialised antenna in males to grip females, controlled by Dll. #EED2026

Khila: ancestral locomotion state of water striders is walking on water, derived and key for radiation, rowing. The rowers are more efficient on water but cannot move to land. They have to escape fishes without going to land: they jump high very fast. #EED2026

Khila: water striders have adapted to all water surfaces, from the inside of flowers to the oceans. The Khila lab hasn't chosen 1 model species, but uses the water strider diversity for different questions. #EED2026

Mantica: while tissue-specific splicing evolves rapidly, it can be conserved at some transitions in evolution, especially neural specific splicing, conserved OTOH among insects, on the other among vertebrates. #EED2026

Jacob Musser: protein language models allow to annotate genes in distant model organisms, for which orthology-based methods mostly fail. #EED2026

Pavloski #EED2026: difference between decidualization and wound healing is loss of recruitment of leukocytes.

Stefan Pavloski: decidualization is similar to wound healing, but ends in decidual stromal cells rather than apoptotic myofibroblasts. Co-option of fibroblast activation? Confirmed by single-cell of human endometrium vs wounded skin. #EED2026

Alison Cole #EED2026: single-cell of Cnidaria identifies cells unique to the jellyfish stage in medusa; these new cell types are close to diverse ancestral cell types, rather than one diversification of a new cell type.

Lotharukpong #EED2026: Similar results with HGT genes, so new genes are rapidly integrated into expression networks in brown algae.
The promoter sequences of brown algae look very different to those of plant or animal model species. Different regulatory starting point for the evolution of multicellularity?

Lotharukpong #EED2026: young genes are expressed in a stage or tissue-specific manner, participating in fast transcriptome evolution. Surprisingly, network centrality similar between young and old genes in brown algae.
