For #FluorescenceFriday we have, "TNTs, cytonemes, and migrasomes, oh my!"

Another fishy #FluorescenceFriday. Even a simple DAPI (blue-yellow) and actin (red) staining can decorate the zebrafish one-day-old embryo spectacularly! 🐟

It's not just the US. The UK is cutting science. Canada is cutting science. No one is cutting transfer of public wealth to big tech and fossil fuel companies though.

I'm absolutely devastated for colleagues at Jodrell Bank who found out this morning that funding for the UK's e-MERLIN radio telescope array will be terminated. This is a short-sighted move, to save a tiny fraction of the overall UK science budget. #SaveJodrellBank 🔭🧪 www.bbc.co.uk/news/article...

Astonishing display of Orcas’ power—pulverizing sunfish. One holds the fish which another rams it all full speed! Hope they don’t decide to ‘sunfish’ humans when they are finally fed up of our polluting shenanigans.

Orcas seen ramming prey so hard it explodes may be playing game

Scientists believe sunfish-smashing behaviour could be form of entertainment or to help younger whales feed

1/2 chameleon & human embryos exhibit an epiblast lumen before #gastrulation initiates. However, they reach this stage via different mechanisms. Our new study @natcomms.nature.com explores early development & lumenogenesis in the veiled chameleon. #evodevo #devbio www.nature.com/articles/s41...

Epiblast lumenogenesis is not a mammalian-specific trait - Nature Communications

Weberling et al. characterise veiled chameleon pre-oviposition development from fertilisation to the initiation of gastrulation and show that pre-gastrulation lumenogenesis occurs via a purse string m...

Very good study from F. Gage’s lab on the impact of #astrocyte metabolism in species-specific neuronal development; possibly key for ‘neoteny’ 🧬🧠🌟 www.biorxiv.org/content/10.6...

A Role for Astrocyte Metabolism in Species-Specific Neuronal Development

Human neurons develop more slowly than non-human primate neurons. This phenomenon, termed neoteny, is thought to contribute to several human-specific features of the brain, including humans' expanded ...

Life as agency. An excellent essay by @philipcball.bsky.social. Can agency he defined? Is it unique to biological entities? Is it evolvable? Do collections of entities show agency? Can neural networks or ecosystems or even Earth (eg Gaia) be defined as “agentic”?

Dear Friends, I just published an insightful review on neural crest evolutionary origin and later transformations. “Co-option and innovation in neural crest evolution”: www.science.org/doi/10.1126/...

Co-option and innovation in neural crest evolution

Neural crest evolution reassembled ancient programs in pigment cell lineage, resulting in vertebrate innovations.
