Thinking about this more, the 2 and 3 year bans are real career killers… who’d hire a tenure track candidate, or an (associate) professor that has one of those hanging around their necks?

We're gearing up to generate iPSCs stably expressing ASAPs, and are compiling a list of potential users who might want these to study cell fate pathways for neurons or cardiomyocytes, or to perform drug screening.

If these would be useful to you, please message me in the chat

Cells drastically downregulate mRNA translation to save energy during stress. A study by the Weis lab (IBC) shows that mRNAs transcribed after stress escape repression while pre-existing mRNA don’t, in a timing mechanism that is independent of mRNA sequence. More: biol.ethz.ch/en/news-and-...

Interesting study about the gender gap in publishing. Not sure if 7% longer review time for female scientists is really something, but I do know that indeed we must prove competence more than our male counterparts journals.plos.org/plosbiology/...

Whole-genome spatial transcriptomic imaging with RAEFISH Nature Reviews Genetics, Published online: 09 January 2026; doi:10.1038/s41576-025-00926-yIn this Tools of the Trade article, Yubao Cheng discusses the development of RAEFISH (reverse-padlock amplicon-encoding fluorescence in situ hybridization), a method that enables spatial transcriptomics with both single-molecule spatial resolution and genome-wide coverage.

CRISPR screens in iPSC-derived neurons reveal principles of tau proteostasis CRISPR screens in iPSC-derived neurons reveal that the E3 ubiquitin ligase CRL5SOCS4 ubiquitinates tau, that CUL5 expression is correlated with resilience in human Alzheimer’s disease, and that electr...

After a long review process, I'm excited that our paper is finally in print: www.cell.com/cell/fulltex...

TL;DR: We use CRISPR screens in iPSC-derived neurons to find a new tau E3 ligase and a relationship between oxidative stress, the proteasome, and tau proteolytic fragments.

Associations between preservative food additives and type 2 diabetes incidence in the NutriNet-Santé prospective cohort - Nature Communications Exposure to twelve widely used preservative food additives are associated with a higher incidence of type 2 diabetes in the French NutriNet-Santé cohort of 108,723 adults, supporting recommendations to favour fresh and minimally processed foods

A study published in Nature Communications reveals that exposure to certain food preservatives, including potassium sorbate and sodium nitrite, correlates with a higher risk of developing type 2 diabetes. 🧪
