For experimental scientists, writing reviews does not equal doing science. Spend the time doing research, making discoveries, and publishing those. I see many CVs of juniorish PIs who write 4:1 reviews to papers. That may build your "brand" but, IMO, is not generally valuable

Why do we still consider (F)ISH necessary to validate scRNAseq data? It is not clear that ISH is a gold standard. We have never failed to reproduce an scRNAseq prediction (from a well QC'd experiment) by FISH. It's time to let that go. It's an enormous waste to time and money.
