This is a powerful account from a PhD student whose fellowship was terminated by NIH because it was part of a "diversity" program without any other considerations or understanding of what the program or the students were actually doing. undark.org/2025/10/09/o... 1/2

NIH Student Grant Cancellation Will Weaken Scientific Innovation

Pre #nephjc bias: Team pro protein All these studies are deeply confounded and based in the pre-kidney-preserving therapy era. Let them eat steak! (Actually, let them eat vegetable sources of protein, but beans, lentils, and soy don’t rhyme with cake)

Chapter 6 starts off with ‘what is a good death’ especially when 1 in 2 children died (see graph below from ourworldindata.org/child-mortal... @ourworldindata.org, in 1950 it was still 1 in 4, and now ranges from 0.3 to 15%) Then pivots to the romanticization of disease esp TB. #NephJCBookClub
