AI slop gracing the cover of Royal Society B. Not only in AI yellow but scientifically nonsensical. Come on. I'm certain human photographs and artworks were ignored to platform ... this.

It was a great privilege to be involved with this paper on a new T2T zebra finch genome, working on the miRNA side of things. Have a read of the preprint now!

Talk from @jfennbio.bsky.social at #ESEB2025 on this work. I didn't catch the actual predictive accuracy in the talk - from the paper, I glean that it's >90%!
Take a look at our work on miRNAs and their involvement with placental phenotypes. It's great to see this work finally see the light of day - huge thanks to everyone involved with the manuscript.
How did mammal placental diversity evolve? miRNAs play a significant role - indeed their repertoire is predictive of phenotype. Congrats to all: esp 1st author @jfennbio.bsky.social & all in @niamhforde.bsky.social group. Thanks to @ukri.org and @leverhulme.ac.uk. www.biorxiv.org/content/10.1...

The day finished off strong with loads of great talks in the Genomics of Evolutionary Innovations symposium!

I'm pleased to report that my talk went well ☺️ 🎨🖌️

I have arrived in Barcelona for ESEB 2025!

I will be talking about microRNA and the evolution of the mammalian placenta on Tuesday at 14:30 in Meeting Room 113

In Nature Genetics, @danielibrahim.bsky.social (MPIMG/BIH) and his team have developed a bioinformatic tool to identify evolutionary conserved regulatory regions of the genome that have transformed so much over time that their DNA sequences have changed completely.

Why do imperfect mimics (such as many hoverflies) exist? We created 3D printed replicas of flies, wasps and our own custom intermediates and then "asked" various predators what they thought of our 3D stimuli. Read all about it here: www.nature.com/articles/s41...

Birds have an excellent ability to learn to discriminate harmless insects from those that they mimic on the basis of subtle differences in appearance.

Mammal placental phenotypes are predictable from microRNA repertoires.
Despite >100 million years of mammal diversification, similar placental morphologies have independently evolved multiple times, presenting a long-standing evolutionary puzzle: what genetic mechanisms ...

When I'm not doing research, I occasionally write about video games, and in this piece that just went up @unwinnable.com I try to combine the two. Specifically, I look at the difficulties of simulating the natural world in a game. Have a read if that sounds at all interesting!
"So how can we bridge the gap between the complexity of the real natural world, and the games which attempt to emulate it: beautiful, impressive, but ultimately shallow simulacra?"

@jfenn.bsky.social imagines how games can incorporate more realistic ecosystems:

A big limitation of videogame ecosystems is their strong focus on predation and conflict.

In my ongoing quest to leave Twitter, I'm hoping use this account for sharing my research, and publicising the work of the O'Connell lab here at the University of Nottingham.

I'm looking at the evolution of microRNA - the discovery of which recently earned a Nobel Prize!
