last week my latest paper on #cycads came out.
The article deals with the idea of cycads as "living #fossils", but what does this mean exactly, and what did we actually test? A thread for #FossilFriday!

Disparity of cycad leaves dispels the living fossil metaphor - Communications Biology
An analysis of leaf disparity through time in cycads shows that this group has a dynamic and expanding morphological diversity until the present, and thus does not fit the ‘living fossil’ hypothesis o...

so both the stories labelling the Sumud flotilla as "Hamas" have been removed from the topic now (as far as I can see)

That still leaves some serious questions about how and why these stories were tagged - what's the process here, and more importantly *why* has it tagged these specific stories?

Palaeonology: A small subject has big questions
The involvement of around 200 researchers from over 30 different countries and more than five years’ work have resulted in 89 “Big Questions” – the most important research questions in paleontology…

Me, @lepidodendron.bsky.social and @rachelwarnock.bsky.social co-led the phylogenetics group and I had such a formative experience! ⚒️

But equally important are the broader needs we highlight:

#Valuing specimen-based research

#Protecting fossil sites & collections

#Strengthening museum infrastructure

#Building a more diverse, equitable, and inclusive community

On the #science side, we dug into:

Drivers of #biodiversity across deep time

Integrating data across #space + time

Using #fossils to inform today’s climate and conservation debates

Harnessing new tools + #technologies

Together, we built a list of 89 #priority #questions, organized into 11 themes.

They highlight both #Scientific #Challenges and the #Structural #Issues shaping the future of paleontology.

Paleontology spans everything from the origins of life billions of years ago to today’s biodiversity crises. The scope is massive, and always evolving.

dx.doi.org/10.1017/pab.2025.10042

So we asked: what should we, as a community, be focusing on next?

“Rich Grenyer, a biologist at the University of Oxford, said de-extinction is a “dangerous” distraction and that gene-edited animals are “at best a sort of simulation, rather like those unnerving animated AI portraits of dead relatives some… people create”.”

Some lovely specimens of the earliest vascular land plants collected last weekend with the Mid Wales Fossil Group from forestry track exposures near Bishops Castle. We think there are probably 2 Cooksonia species here in the Silurian rocks. There were also tiny fragments of Eurypterids #FossilFriday

Please share! I'm looking for a postdoc. The position is to lead one of the following projects: 1) regulation of plant specialized metabolism by cell fate, or 2) foliar embryogenesis in the succulent plant Kalanchoe.

Learn more abt projects: cxli233.github.io/cxLi_lab/res...
Plant cells are totipotent, meaning individual cells have the potential to develop into a full organism, a property unique to the zygote for animals. However, in most species for most cells, plant cells are not spontaneously totipotent, since they must be treated with specific hormone combinations to unlock their totipotency. Species within the Kalanchoe genus is unique as they spontaneously develop foliar embryos that are fully realized plantlets with shoot and root from notches along the edges of leaves. We speculate that the progenitor cells that give rise to these foliar embryos are totipotent, and we are using single cell techniques to identify & characterize them. In addition to being a fundamental process for plant biology, we foresee unlocking totipotency has many biotechnological applications, such as faciliating genetic transformation and the development of synthetic organs of biomanufacturing.
