#StandUpForScience in the Netherlands? Anyone?

Hi, scientists from the Fediverse! It seems that Nature is asking people about Twitter migration and if they are happier on #bluesky .

On Nature writers' minds, Bluesky is the only place to migrate to. There's not a single mention of the Fediverse in there! However, there is a small free text box where you can write your thoughts, in the step before "send" button. So I did fill the poll anyway, writing why I decided not to go to Bluesky but to Mastodon instead.

I thought that maybe if we get enough people to actually fill the survey and mention that they migrated to Mastodon, we can make a stronger case for open, free networks. It's an extremely short survey, so let's try! https://www.nature.com/articles/d41586-025-00037-y

Has Bluesky replaced X for scientists? Take Nature’s poll

The research community has flocked to the social-media platform Bluesky. Tell us about your experience.

Centuries ago, I published a manuscript on BioRχiv about the love/hate relationship between variability and robustness in embryogenesis.

And now, it's published in Science! I am so proud 🥳

https://www.science.org/doi/10.1126/science.adh1145

We went through three (3!) rounds of revisions. Although we did not change a comma in the abstract, the revisions improved the quality of the work very much (we nearly doubled the sample size and added an entire figure).

Eight studies reveal a (possibly universal) bias in human imagination

Experimental History
When looking at a moving object, the human brain can compensate for delays accumulated during neural processing by extrapolating the trajectory of the object to determine its real-time position. https://elifesciences.org/digests/82424/compensating-for-a-delayed-relay?utm_source=mastodon&utm_medium=social&utm_campaign=organic
Compensating for a delayed relay

[ preprint ]
Stochasticity controls robustness in embryogenesis.

Although it may sound counterintuitive, this is one of the conclusions we defend in our preprint "Temporal variability and cell mechanics control robustness in mammalian embryogenesis" (bioRχiv: https://www.biorxiv.org/content/10.1101/2023.01.24.525420v1)

1. Variability in cleavage timing is surprisingly not regulated at all in mouse embryos (similar observation in rabbit and monkey). We showed that cleavage timing is compatible with a simple accumulation of randomly shorter/longer cell cycle lengths leading to desynchronisation.
From now on, I will officially use Chat GPT to make my figures /i.
