RNA-seq tells us how much RNA is present in the cell. But to understand gene regulation, we need to easily measure the synthesis and decay rates driving this abundance. We introduce AIR-seq: analog intrinsic recoding sequencing. (1/6) www.biorxiv.org/content/10.6...

What I like about preprints: They don't come with any baked-in impact-factor-like imprimatur that elevates some over others. What would be valuable: An AI-based system that learns a user's scientific questions, and converts the firehose of preprints into a gentle, personally-curated stream.
