I’ve been listening to the Hey Jude episode and his depth of knowledge and insight is stunning.

When you zoom out from individual genes to consider the context of whole chromosomes across animal diversity, animal evolution takes on a different look. Oleg Simakov and I published a review in @annualreviews.bsky.social on topological approaches in comparative genomics. 🧬 doi.org/10.1146/annu...

I am always amazed by time-lapse animations showing the progression of a drawing.

From our new paper out now in @currentbiology.bsky.social: www.cell.com/current-biol... w/ @neurofishh.bsky.social @gkafetzis.bsky.social @denilsson.bsky.social

Looking across animals, the vertebrate eye is an obvious outlier. Why is it so different that other highly visual animals?

Looks great! Sorry if this is in the documentation but can it do 3-D with two orthogonal cameras?

Gigantocypris is always a crowd-pleaser, but I have never seen those black amphipods!

Related to high pressure, @ibudin.bsky.social and Jacob Winnikoff led a study which showed that a particular lipid headgroup (PPE) is more abundant in membranes of deep #ctenophores. πŸ§ͺπŸ¦‘
What was amazing was when they put PPE into bacterial membranes, the bacteria became more pressure tolerant!

The re-analysis of this #sponge #ctenophore study made me realize how important it is to really *look* at your data.
Their filtering pipeline was meant to retain "strong" genes, but many of them had NO ctenophores and most had polyphyletic sponges.
Time to put down the pitchforks for a while.

β€˜Cleave’ can refer to splitting something apart.

β€˜Cleave’ can also refer to the uniting of two things.

…what?

A word that is also its own opposite is called a β€˜contronym.’

My least favorite words (one category at least) are ones like nonplussed, inflammable, shelled, which can either mean one thing…or the exact opposite.
