Neurogenesis in Milkweed Bug: New Insights Revealed Recent studies have brought to light fascinating insights into the neurogenesis processes occurring in the milkweed bug, Oncopeltus fasciatus, a species that diverges in significant ways from the

It got a very strange write-up in Scienmag. Looks AI generated and not a very precise description of what the paper actually says, but there is no such thing as bad publicity.

Cover of book titled The Tree of Life: solving science's greatest puzzle.

My book 'The Tree of Life' is published in the USA and Canada today.

Available as book, on kindle and as audio.

I would be really grateful for reposts.

I concur. We saw it at the Jerusalem Film Festival this summer and it is frightening how prophetically accurate Orwell was in many things.

Hope to be able to make it to this workshop. Looks fantastic!

Exploring the interplay between tanning, desiccation resistance, and calcium metabolism in cockroaches The successful terrestrial adaptation of insects has been recently suggested to be significantly influenced by a novel cuticle modification mechanism …

New paper from the lab just published, Led by post-doc Olga Volovych on tanning and calcium metabolism in roaches. This is the lab's first foray into insect physiology, so all the credit goes to Olga and her excellent work.

Ksenia Juravel (almost my student - long story) talking about Paleogenomics of the fauna of the Hula valley. Looking at animals found in a site from the earliest human habitation. DNA from ancient cats and gazelles!

Keynote by Federico Brown. Cave planarians have a very long eversible pharynx. If it dissected out, it continues to search for food and even ingest food autonomously. 😱
#ICIM6

That should be #ICIM6, of course.

Opening keynote of #ICIM5 by Graham Budd, giving an excellent overview of early animal evolution and the overlooked fossil record of trace fossils and small shellies. He also gave tribute to Claus Nielsen’s influence on the field. Great start to what will hopefully be a superb meeting.

Knowledge and teaching in the age of information The advent of the World Wide Web in the turn of the last century completely transformed the way most people find and absorb information. Rather than a world in which information is stored in books or ...

I have published a post on the Oxford University Press blog that outlines my teaching philosophy, and the philosophy behind my Textbook "Organismic Animal Biology - An Evolutionary Approach". Have a look, and if you agree with my philosophy, buy the book and use it.

If you want to discuss #networks in #evo-devo, you should join this year's satellite symposium of the @dzg2025berlin.bsky.social organized by the developmental biology section (@marketa-kau.bsky.social, Benjamin Naumann, Alexander Klimovich). I will talk about gene regulatory networks.

On my way to a 2-conference, 2-continent trip. #ICIM6 in Concepcion, Chile, followed by #ESEB2025 in Barcelona. My first time in South America. Very excited!

I agree, but in the last two years “our” problems have gotten significantly bloodier than the NI conflict ever was. The path to peace is much longer and more difficult than it was.

Unfortunately it’s clear that the Israeli people can’t topple the government or change its ways. Seems like the attorney general, the last gate keeper, will be fired soon. As long as we’re stuck with this government, the war won’t stop. Only international intervention (=the U.S) might do it.

This is presumably a result of Ind1 misexpression in Ventral Europe.

A couple of years ago, I published a paper in @sicbjournals.bsky.social . The guidelines stated that you could include an abstract in as many languages as you want. I took this as a challenge, and together with friends and colleagues put together translations of the abstract into 8 languages.
1/8.

Nice update of the @moultdb database, with iNaturalist observations integrated with genomic data and scientific observations from extant and fossil species!
