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...

"Then, in 2021, the Princeton University geneticist Coleen Murphy found that Caenorhabditis elegans worms could learn to avoid a pathogenic bacterium by eating, or even just swimming around in, pureed worms who had learned the hard way." www.quantamagazine.org/are-memories...

In the 1960s, worm-training experiments and their strange implications captivated the nation. Columnist Claire L. Evans follows the neuroscientists who attempted to recapture the magic.

Thrilled to see this out today in PLOS Biology. With postdocs Siqi Liu and Flávio Costa, we ask why the gut microbiome loses its balance with age. It's an Unsolved Mystery piece: a framework, not a finalized account, with predictions we lay out for the field to test. 🧵

Host-associated microbiomes are stable across most of the lifespan, but what drives late-life deterioration remains unclear. @dvalenzano.bsky.social &co propose interventions that restore #immune surveillance capacity alongside ecologically informed #microbiome management. 🧪 #aging

Aging may feel gradual… but what if it’s not? In our recent paper, we tracked fish continuously from puberty until death. This gave us a unique view of how aging unfolds across the adult lifespan. 🧵

Great work from Claire, Ravi, and the whole team– the initial lifelong continuous screen of behaving vertebrates provided a wealth of ideas on progression/staging of brain function across lifespan. Behavior is unmatched as a noninvasive quantitative readout of brain function (and, one that matters).

Youthful antics predict lifespan? Using machine learning & continuous recordings of #killifish behavior from adolescence until death, @brunetlab.bsky.social & @deisseroth.bsky.social find early-life behavior predicted future lifespan! Now published @science.org: www.science.org/doi/10.1126/... 🧪 1/2
