Tremendous paper from Narry Kim’s lab identifying a sequence element that recruits cellular factors to exogenous mRNAs to ‘rejuvenate’ their poly(A) tails leading to a huge boost in output. Significant implications for therapeutics. Now, I wonder what the factor X is…

I’m perfectly fine with journals conducting reviews by their editors. What we, as a scientific community, need to learn is how to decouple journal titles from assessments for hiring or promotion.
The idea is to decouple the journals from the review step. They’ll still exist, but they’ll need to add other value. They’ll highlight, curate, add new perspectives. If they do a good job they can still be prestigious (like Scientific American or Wired) (1.2) 👇

DICER1 hotspot mutation induces 3p microRNA gain of function via Argonaute strand switch
Nature Structural & Molecular Biology, Published online: 04 November 2025; doi:10.1038/s41594-025-01671-wMalagobadan et al. show that a DICER1 hotspot mutation, previously thought to cause partial loss of function, also leads to unexpected gain of function by activating normally silent 3p passenger microRNAs, revealing a strand-switch mechanism in tumorigenesis.
