What if damaged human kidneys could one day repair themselves? At MDI Bio Lab, Iain Drummond, Ph.D., and his team have identified inflammatory signaling pathways in #zebrafish capable of triggering the production of new, functional nephrons without injuring the kidney itself. 🧪 🐟🎸 #NephSky #RenalSky

Sigolène Meilhac @meilhacsigolene.bsky.social will be speaking on "Congenital structural heart defects" at our Journal Meeting in the UK this September #HumanDev26 Register to attend: biologists.com/meetings/dev... Abstract deadline: 12 June 2026

Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...

Finally, footage from that new whale graveyard. The fact that fossils and fresh carcasses mix together in this spot is bonkers. But of course it makes sense, because the scavengers that live down there also need a steady supply over millions of years. They can't just suddenly adapt to the deep.

Very excited to be sharing our new paper, just out in Nature Cell Biology! The big question we investigate: How do migrating cells put their front 🔴 and back 🔵 in the right place?

“If the cells are frequently turning over but there is still viral persistence, what other plausible explanations are there for this other than replication?” That's a very good question someone asked, let's do a thread about VIRAL PERSISTENCE in #LongCovid to cover this! (1/10)

Move over, elephant graveyards - this whale necropolis extends 1,200km along the Indian Ocean seafloor at depths from 4,600-7,000m; has accumulated at least 476 fossil whale carcasses over the past 5m years; and has 5 active whale falls. Paper in @nature.com www.nature.com/articles/s41...

How do cells tune PRC2 allostery? We find EZH2 Ser21-phos restrains PRC2 adoption of the compact active state. Loss of this restraint promotes H3K27me3, redistributes cPRC1, and impairs differentiation. New bioRxiv with @kasinath-lab.bsky.social & @garcialabms.bsky.social! tinyurl.com/4369kmh2

The new OrthoFinder paper is out now! In this new work, we introduce major advances in accuracy and scalability, allowing analysis on much larger datasets www.nature.com/articles/s41... github.com/OrthoFinder/...

I am sending an open letter to Thermo Fisher. Their response to my response to their manipulated western blot is bullying and petty. Yes, this western blot really is manipulated, it is unfair on me to say otherwise. I don't make those accusations lightly, and I have a (minor) reputation to defend.

#Bugsky 🐙🌿 Shared with me by a fof in SoCal - this is a gynandromorph (both male & female) valley carpenter bee (Xylocopa sonorina). Females are black, males orange, so the extreme color dimorphism really stands out. Per Doug Yanega at UC Riverside, bee gynandromorphs he’s seen are mosaic instead—

I've had several discussions with folks who asked me about APC and Wnt signaling only to realize they meant the APC/C of the cell cycle. YMMV.

Project. 🎸☕️

Don't confuse 'canon' for 'cannon', or you'll blow yourself up & that's strictly forbidden by the Church. CANON derives from Greek 'kanōn' which was a straight measuring stick or sturdy reed. "Canon" is used by the Catholic Church to refer to official decrees: meaning 'measuring sticks of law'.

Fun facts about #pupfish: Actually a kind of #killifish, they get their names from their active and playful lifestyles. But don't let the name fool you, they are famous extremophiles and can withstand lethally high water temperatures, high salinities, and extremely low oxygen levels. #TeleostTalk 🧪

A lot of attention is paid to craft traditions in Western Europe and North America, such as handsewn Hermes leather goods and bespoke Savile Row suits. But the uneven focus leads some to believe that things made outside of these places are low quality. This is not true. 🧵

Human activity may be enabling the expansion of golden jackals across Europe by reducing the suppressive effect of grey wolves, suggests research in Nature Ecology & Evolution. This human-mediated interaction could allow jackals to occupy up to 75% of the continent. go.nature.com/4nLOJ5O 🌍🧪
