I am seeing a lot of posts about Rosalind Franklin that themselves ignore her publication record on DNA!

In fact Franklin and Gosling's paper, including the famous Photograph #51, was published, along with Wilkins's paper, back-to-back with the Watson and Crick paper in Nature in 1953.

I learned a lot from reading the posts over the last 2 days. I was struck by how much we are influenced by scientific mythology, some of it rooted in what we learned as far back as high school.

Just read the full letter. Wow !

« But the point of science is what is discovered, not how it was discovered or by whom. It is the results which need to be brought home to the public. »
F. Crick.

I recommend reading this thread from F. Crick’s granddaughter.
Apparently even the scene at the Eagle pub, where we all went as scientific pilgrims, is not true?
Just mythology
"If you publish your book now, in the teeth of my opposition, history will condemn you”

“the tone used to describe Rosalind's work in the Epilogue
is perfectly reasonable,
but contrasts ludicrously with
the descriptions of her
in the text itself.”

-Francis Crick

Letter criticizing Watson’s book 🧪

You know what? I did not read “The Double Helix.”

I was converted to molecular biology by the books from Monod and Jacob, real decent and courageous men in addition to being exceptional scientists. For me, one cannot go without the other!!

Some still praise James Watson despite his racism. Same with colleagues who won’t condemn Elon Musk’s politics, hiding behind “scientists shouldn’t mix science and politics.”

Many thanks to the folks at the San Diego Supercomputer Center for highlighting our project!
SDSC-housed Protein Data Bank Brings Molecules Up to Size
Molecules — the unseen architects that form everything from the DNA in your cells to the planets in distant galaxies, crafting the very fabric of reality while remaining too small for the human eye to glimpse. But thanks to the Protein Data Bank we can now “see” these hidden wonders.

Great collaboration with @guo-lab.bsky.social to determine an in situ architectural model of the Tad pilus machine. Be on the lookout soon for a preprint on the same topic by Grant Jensen and @viollierpat.bsky.social. #microsky

A recent cool preprint by John Whitney's lab on a new family of antibacterial proteins secreted by Gram-positive bacteria that enter and kill a broad spectrum of bacteria. Cell entry is receptor-independent and relies on cleavage by a co-secreted protease and the PMF.

Proteolytically activated antibacterial toxins inhibit the growth of diverse Gram-positive bacteria
Many species of bacteria produce small-molecule antibiotics that enter and kill a wide range of competitor microbes. However, diffusible antibacterial proteins that share this broad-spectrum activity ...
