Happy to share this newly published work on how acute social stress shapes immune gene expression. In this study, we followed changes in blood gene expression over 90 minutes after an acute psychosocial stressor. doi.org/10.1016/j.bb...

This is one of the most exciting IBD papers of 2026 so far!!! 👇🏼 Every now and then, a study comes along that fundamentally changes how we think about disease mechanisms. This is one of them. www.nejm.org/doi/full/10....

What’s the alternative? Have PhD students that you don’t mentor? Is an unmentored PhD student really a student?

AI in biology: "I read about some new computational method...get excited because it’s exactly what I need...I try the method...Most of the time things don’t work...I have seen this play out so many times my default assumption is nothing is going to work" blog.genesmindsmachines.com/p/we-still-c...

We still can’t predict much of anything in biology

I never imagined I'd see this day, but clearly I didn't have enough imagination. NIH is going to terminate ongoing (and of course all future) research that focuses on gender identity, inclusion, environmental justice, anything "deemed DEI" etc. www.nature.com/articles/d41...
nature.com
Exclusive: NIH to terminate hundreds of active research grants
Studies that touch on LGBT+ health, gender identity and DEI in the biomedical workforce could be terminated, according to documents obtained by Nature.

NIH hoitaa tieteen hakukoneita, jotka ovat joka päivä välttämättömiä bio/lääketieteessä koko maailmassa. Ne ovat nyt kaikki kumossa. Ei liittyne siihen, että DOGE veti eilen töpselin kokonaiselta valtion IT-osastolta. Mutta muistuttaa, miten tärkeä USA on koko maailmalle - eikä vain sotahommissa.
