New idea to end the measles epidemic: anti-measles peptides Just make sure they bind all sorts of different HLAs Product of our lab‘s germinal center meeting today, I guess we went slightly off-topic

"Increasing diversity of participants in studies increases geneticists’ chances of finding variants that are important to health, & lessens likelihood of drawing spurious conclusions about genetic or other factors driving disease..." Key statement for human genetics community to endorse & spread.👇🧪

Eugenics is on the rise again: human geneticists must take a stand
Scientists must push back against the threat of rising white nationalism and the dangerous and pseudoscientific ideas of eugenics.

His Schenkerian analysis classes were the closest I had to a scientific education in college. But if you only know him from his brilliant harmony and counterpoint textbooks, you’re missing what an amazing artist he was as well. Rest in peace Carl, music will miss you.

Spoiler alert: you have to treat the organism. & people who think in silico approaches are ready to replace animal models should not be included in adult conversations (ppl who want to develop them, very welcome, it's those who think they are ready for prime time that need to fuck all the way off)

In my simple brain, it's exciting but you need to understand the limitations: cell free systems allow you to ask q's about molecules; in vitro systems allow you to ask q's about molecules & cells; organoids may one day allow you to ask q's about mols, cells, and tissues/organs - but never organisms

We are not really there yet, not even close. The most valuable (in market terms) drugs out there today come fm understanding the incretin effect, the unexpected finding that oral & iv glucose provoke different insulin response. Can you see a road to that from any of the current animal alternatives?

Gabriel Victora @victora.bsky.social · 24/02/2026
Could go both ways. Feedback helps favor non-dominant clones like bnAb precursors, but it might make it harder for these clones to mature for long enough if at some point they do become dominant
