In the twenty years after the draft human genome was first released, the average sequencing cost per genome fell roughly one hundred thousand-fold, ending up just north of $500. In that same period, the cost to sequence a million letters or “megabase” of DNA fell to six tenths of a cent.2 This plummeting price is due largely to technological innovation, including new sequencing chemistries, computational methods for assembling raw reads into finished genomes, and highly efficient commercial sequencing machines.
The journals then paywall your work, sell the access back to you and your colleagues, and pocket the profit. Universities cover these subscriptions and fees by charging the government “indirect costs” on every grant—money that doesn’t go to the research itself, but to all the things that support the research, like keeping the lights on, cleaning the toilets, and accessing the journals that the researchers need to read.
