Maternal nutrient sensing regulates ribosome provisioning to the next generation. Maternal dietary restriction and reduced mTORC1 signaling in the pharynx through the Rag GTPase RAGA-1 regulate the amount of translational capacity deposited into embryos. As a result, progeny of dietarily restricted mothers inherit reduced levels of ribosomal proteins at hatching. Although embryogenesis proceeds normally, larvae begin life with lower translational capacity, leading to smaller size and slower early growth until ribosome levels recover during larval development. The diagram was generated in BioRender.

Animals adjust their #proteome to match the environment, but can the proteome can be propagated #transgenerationally? Elif Cenik explores a @plosbiology.org study showing that maternal nutrient sensing regulates ribosome deposition into embryos. Paper: plos.io/4tMpQJe Primer: plos.io/41qOzGT

Want to make your code better at running again in the future?

My talk next month will be filled with lots of tips about how to write sharable, reproducible R code and why it's good for science

Hope to see you there!

BBSRC, NERC and Future Leaders fellowships are fantastic opportunities for ECRs to transition to independence. My institute (IVES) at Liverpool Uni is keen to support applicants (vet/ecol/evol/infection/omics etc.). Get in touch with me (ives.fellowships@liverpool.ac.uk) if you're interested!

This sounds like a crazy project, you must fill me in on what you are up to. Sounds super interesting!

Whaaat thats wild!

Point of no returns: researchers are crossing a threshold in the fight for funding With so little money to go round, the costs of competing for grants can exceed what the grants are worth. When that happens, nobody wins.

Scientific funding is a net negative: "European taxpayers will have spent more on the funding process than on the funding itself, and the scientific ecosystem has been drained"

Been looking at these ARC changes. If they go through - as early as next year - I assume this means DE26 & FT26 will be the last time these schemes run. If that's the case - big decision for people putting in this yr, that's a lot of work for only one chance at the schemes (rather than the usual 3)
