This 1,700 Year Old Egg Never Broke—And Now It’s Further Stunning Scientists

They still can’t fully crack the mystery.

Comme je passe par là, je voulais partager un truc que j'ai appris à propos du congrès international d'histoire des sciences tenu à Londres en 1931.

Ce congrès est un moment important de l'historiographie dans ce domaine. C'est à cette occasion qu'une historiographie marxiste des sciences a pu se mettre en scène et que la divergence d'approche internalisme/externalisme a pu se cristaliser (voir infra)

'Now, scientists have discovered that Leonardo did detailed experiments that sought to illuminate the nature of gravity a century before Galileo and some two centuries ahead of Newton’s making its investigation an exact science. The scientists’ study of his gravitational ideas and experimentation was published earlier this month in the journal “Leonardo.”

A Doodle Reveals da Vinci’s Early Deconstruction of Gravity

Long before Galileo and Newton used superior mathematics to study a fundamental natural force, Leonardo calculated the gravitational constant with surprising accuracy.

As a side note, I am passionate about the roots of #Neuroscience #Neurophysiology and #Psychology (17th-18th-19th centuries)... about which I try to be a book collector, but unfortunately I don't have enough time or money to be a professional!
I love reading the early (late 19th and early 20th century) Neurophysiology classics because I find them so genuine and often still relevant.

Thirty years ago, in November 1992, Ishida, Honjo and their collaborators reported the discovery of the #PD1 gene in @embojournal

https://www.embopress.org/doi/abs/10.1002/j.1460-2075.1992.tb05481.x

I spoke with Tasuku Honjo, Pierre Golstein (whose team first cloned #CTLA4) & Facundo Batista about the discovery earlier this year.
The initial project had absolutely nothing to do with checkpoints or #immunotherapy
