Finally, the BBC 1970s version is very “Dark Ages” in feel, so realistic in that sense. We found it on YouTube, but it was in such poor technical quality we gave up after a few episodes.

And if you are looking for cinematic retellings, John Boorman’s Excalibur is a masterpiece. Avoid all 21st century retellings.

The Seeing Stone trilogy is aimed at young adults, but is also great for older adults. It does a very good job of putting the legends in a historical perspective, both of when they supposedly took place and of when they were retold.

I just finished re-reading The Once and Future King. It is brilliant on many levels: Its self-conscious anachronisms (now anachronistic themselves). Its British humour. And especially now, its uncompromising pacifism, and lamentation about how good ideas by good people are destroyed by evil people.

New preprint!! 🌟📝

Can we tell if a horseshoe crab will moult ?
Will it moult tomorrow or maybe in a week? 🤔👀

In this study, we developed a simple and non-invasive approach in determining the moult stage of the Atlantic #horseshoe crab by looking at key structures. #inverts #science

Insect research has used Drosophila as a model organism for over a century. But today’s tools now open up a much wider spectrum of insects which deserve to be studied. See the recent commentary in @fly-journal.bsky.social by @peterkdearden.bsky.social, ‘Why just fly?’ doi.org/10.1080/1933...

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.

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. 😱

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.

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.

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.
