For another year, it appears, this article I wrote with @nccomfort.bsky.social is the most read of @nature.com's News articles...
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

Brilliant article ⬇️
I didn’t know it worked this way. @nytopinion.nytimes.com first published my piece on Watson and genetic determinism on Sunday, but it came out in the paper today. Evidently each week the op-ed page is a mad shuffling scramble for Friday.

It used to be, because swimming is still very largely a sport off teenagers and those up to 25 but the trend is upwards, with Olympic champions of 27 and into early 30s, all distances no longer 'all but unheard of'. Worth noting: Jordan hasn't retired; its a 'see ya'; likely, we'll see him again
