🥳🎉 Congrats @ritoghose.bsky.social and @sdelcilab.bsky.social Beautiful data!!

Functional liver genomics identifies hepatokines promoting wasting in cancer cachexia Cancer-induced liver changes promote body wasting through secreted factors, with circadian regulators and hepatokines being important contributors to cancer cachexia.

Part time (20h per week) technician/predoc position available in my lab at the University of Barcelona 🧬⏰ studying circadian rhythms & inter-organ crosstalk.

Yeh a lot do for sure- its really sad- about 50% voted for him at least (49.9% of popular vote was for Trump in 2024). Reminds me of the percentages for Brexit in UK (another terrible and embarrasing decision), 52% for, 48% against. Signs of deeply divided populations...

🧪 Encouraging to see people standing up against tyranny and fascism in the US. The Trump administration’s anti-science and pro-war agenda isn’t just dangerous at home — it threatens progress and stability worldwide. Enough!

US science is being wrecked, and its leadership is fighting the last war Facing an extreme budget, the National Academies hosted an event that ignored it.

The failure of the National Academy of Sciences USA to make a clear and unequivocal statement about the disastrous Trump administration science policies — it lets all of us down and dooms them to eventual irrelevance.

US science folks: it's been really heartening to see all the Stand Up For Science posts. Thank you for showing the backbone and resolve that most institutions have lacked.

Great to see US scientists protesting in response to the insanity that is the US "government" right now. @standupforscience.bsky.social 🧪

As we age, our circadian clock goes off-track, which may contribute to age-related diseases. A new review paper gets into the mechanisms and potential ways to prevent the decline www.nature.com/articles/s41...

Congrats to you, your team and collaborators on a series of amazing manuscripts! 👏🤯

Wow, this is quite wild!

Hi Pancho, can I be added please? 🙏

It seems easy to make fun of basic science – for example why would you want to study bacterial immune systems? But then you would have to admit that that’s exactly what led to the discovery of using CRISPR as an insanely good technology for genome engineering.

Hi Christian, could you please add me to this? 🙏 all the best

Wow, this is cool. Non natural cis elements designed in silico that are more effective than natural

Hi Nicholas 👋, could you add me please 🙏🕙💪 www.cell.com/cell-reports...

This month we published 2 MANUSCRIPTS in @natureportfolio.bsky.social , nature communication
1. Natalia Pardo discovers the role of nuclear MTHFD2 in centromere stability
2. Espinar and Garcia-Cao reveal the role of nuclear IMPDH2 in the DNA damage response.

Nuclear Metabolism is on 🔥

Hey @biorxivpreprint.bsky.social, I think you need to add another icon here 🦋

word cloud showing research focus of Jacob Smith. Main words are circadian, clock, liver, muscle, metabolic

🧪 Word cloud from papers to date. I'd say it sums up my research focus pretty well! (scholargoggler.com). Thanks to a post from ‪@mojoshark.bsky.social‬ for the idea
