We now have 4,426 trees for published articles and 12,662 trees for peer reviews in The Forest of Biologists. Thank you to everyone who has contributed.

Excited to share a new preprint from the lab, by @andrewmatheson.bsky.social and team, where we dive into the superpower of newts: plasticity! www.biorxiv.org/content/10.6... Like many good projects, this started with a serendipitous observation... 🧵1/5

I am excited to open my lab at @ibioillinois.bsky.social in Spring 2027! We will use zebrafish & other fishy friends to reveal the genetic basis of large scale changes in the vertebrate body plan, and how this impacts both human health and evolution. Join me at UIUC! 🧬🧫🔬 www.hawkinslaboratory.com

„Forschung ist kein Selbstzweck. Forschung muss zu Wertschöpfung, Produktion und Innovation in Deutschland und in Europa führen“, so der @bundeskanzler. Die Wissenschaftsfreiheit, wie sie Art. 5 Abs. 3 GG und das Bundesverfassungsgericht verstehen, setzt einen anderen Maßstab. 🧵 1/n

Had a conversation yesterday with a PI who said that using LLMs "equalizes the board, because now anyone can get feedback on a manuscript or talk science that otherwise would not have access to" and I wonder in what world some people live 🧪

New paper from the lab! We show that laminin α5 and two integrin receptors (α3, α6) team up to guide a group of cells moving together inside a living embryo (doi.org/10.1242/dev....) Congrats Anna & Nicola. Thanks to @chaitanyadingare.bsky.social and all authors, and to @dev-journal.bsky.social.

Even more zebrafish😍 #EZM2026

Already spotted some #zebrafish in Vienna #EZM2026

If you are a researcher that uses slop machines to create figures for your talk, you are embarassing yourself

Already spotted some #zebrafish in Vienna #EZM2026

Our team is already gathering in Vienna at the #EZM2026. Looking forward to meeting you all! 🐟🐟🐟

I am attending the Vienna Zebrafish meeting next week. Who from y'all am I going to see? #EZM2026 🧪🐟

We're very excited to announce the official launch of the Journal of Regeneration. Together with the amazing team from @pensoft.net and my two co-EICs Loriano Ballarin and Buki Rinkevich, it is such a pleasure to share this new platform for bringing together the regeneration biology community.

Journal of Regeneration

 Journal of Regeneration is an international peer-reviewed, Open Access journal aiming to provide a platform for the dissemination of research results on regeneration and tissue repair across phy...

New research finds that the ovaries of old mice become infiltrated with immune cells and may secrete immune signals into the body. The consequences of these changes aren’t clear, but a similar transformation in humans could have health implications after menopause. https://scim.ag/4oJAGOK

After menopause, ovaries may transform into organs with immune powers

Mouse and human data suggest ovaries develop a new function after reproductive duties end

Excited to share the final published version of our work on the evolution of dorsal-ventral patterning in fins and limbs, now up on @currentbiology.bsky.social In review we added new single LARM element deletions to assess their impact on dorsality. Take a look! 🔬🧪🐟🐁 www.cell.com/current-biol...

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

Read about how research into lymphatic function is changing our understanding of immune regulation in the lungs in our review: doi.org/10.1016/j.co... Congratulations to co-authors Amy Rivers and Camila Migues Ramirez!

The array of organs in the animal body differ dramatically in their architecture, but cell-cell adhesion mediated by cadherins is a common principle. Our lab usually focuses on epithelia but cadherins are also active in migrating mesenchymal cells like these migrating testis myoblasts 1/n 🧪

As Editor of @dev-journal.bsky.social I get asked "What are you doing about your impact factor?" In our new editorial we say: Ask not what Dev can do for the impact factor. Ask what you can do for Dev's IF The IF is about how we all cite, review & assess each other's work doi.org/10.1242/dev....

Summary: This Editorial offers an honest look at impact factor trends in developmental biology, explains how Development serves its community, and makes the case that sustaining developmental biology ...

New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient la...
