Thrilled to post thread re: new single-cell lineage of mouse embryo reconstructed w/ DNA Typewriter. One animal, zygote to late organogenesis (E13.5). Tree has 1,340,794 transcriptionally profiled, annotated tips (cells), 1,142,588 dated internal nodes, rooted at zygote 1/n

You see everything is connected. The marine heatwaves off the coasts of Europe make heatwaves on land more intense, which in turn dries out vegetation, which then creates perfect fire weather conditions. Brought to you by the world's refusal to drastically reduce the burning of fossil fuels.

In late May 2026, several countries in Western Europe faced above-average temperatures. During the same period, large areas of the Atlantic Ocean and the Mediterranean Sea also recorded above-average ...

The third chapter in our coral single-cell trilogy is here. After mapping cell type diversity in Stylophora (Levy 2021) and exploring facultative symbiosis in Oculina (Levy 2025), we now uncover cell type-specific responses to heat stress. Find out more in @xgrau.bsky.social's thread below.

Cell-resolved transcriptional responses during heat-induced coral bleaching and recovery

Coral reefs depend on an intracellular symbiosis between cnidarian hosts and photosynthetic dinoflagellates that is disrupted by ocean warming, causing coral bleaching. Yet how these responses are dis...

I'm happy to share our latest on #coral single-cell biology: a transcriptomic timecourse of heat stress in Stylophora pistillata, from bleaching to recovery 🪸🌊 This project was spearheaded by Shani Levy and carried through in @arnausebe.bsky.social's lab at @crg.eu. www.biorxiv.org/content/10.6...

🇪🇸 🇪🇺 El Parlamento Europeo deja pasar el #ChatControl 1.0 pese a que una mayoría votó en contra (314:276), permitiendo el escaneo masivo de chats privados hasta 2028. Las víctimas advierten de sus riesgos. Mi análisis 👇 […]

🚨 #ChatControl 1.0 HAS PASSED - despite a majority voting against it (314:276) 🚨 After the EU parliament has rejected #ChatControl TWICE in the past, it has been pushed as an urgent procedure for a new plenary vote. TODAY the EU parliament has voted YES for #ChatControl 1.0😡

More than a decade since CRISPR-Cas9 knock in came on the scene, it's remained underutilized in emerging models. Using transposase, and a split-FP system, we built an optimized knock in system for use in the genetically-enabled urchin, Lytechinus pictus. bit.ly/4wswLsd

What if an embryo made immune cells before it finished building the tissue they usually come from? In our new preprint, we show that annual killifish embryos specify neutrophils before germ layers are fully resolved. www.biorxiv.org/content/10.6... Huge thanks to my PI, @ohnolog.bsky.social ! 🧵

Early immune cell development precedes gastrulation in annual killifish

During embryogenesis, cell types arise in a predictable order because developmental regulators act sequentially. But how evolutionary changes in morphogenesis reshape the signaling environments that a...

Planetary instability unleashed by burning fossil fuels. But Reject Surrender. Reject false tradeoffs bw mitigation & adaptation, AC vs no AC. All climate scientists have the same take as Holdren: 'We need enough mitigation to avoid the unmanageable, enough adaptation to manage the unavoidable"

To AC or not to AC is not the right question. The right question is how to reduce suffering and death from extreme heat. AC is just one tool. It is not a technofix for life on a superheated planet.
