🚨 New preprint out!
We reconstructed parental haplotypes in >440k individuals (UK & Estonian biobanks) to estimate assortative mating directly in the parental generation.
This reveals intensified assortment in recent generations.

History of Molecular Biology Collection
This unparalleled collection includes Rosalind Franklin's historic 'Photo 51,' which revealed the double-helix structure of DNA.

I'm disturbed by tenured faculty on here behaving like high school bullies.
I ask them to look up ad hominem and recognize that what Mamdani did was atrocious and newsworthy.
Why are we defending an uber-privileged applicant whose father was faculty at the Ivy League university he was applying to?
