'In short, human genetics has become an evolutionary science in a way that can’t be undone. You cannot meaningfully study how humans function or differ from one another without understanding how evolution has shaped us.'

What I told my students about the threats to evolutionary science

I was floored by the question, but it matters. With U.S. funding crashing, what will happen to the future of the field?

Delighted our study (7+ years in the making) is out today in Nature. In a nutshell, 48 hours of antibiotics in week 1 led to impaired vaccine responses up to 15 months later in infants. We show (in-vivo) a probiotic can fix it #microbiome #science #immunology

Letting mice experience the "wild" alters their immune system, especially their B-cells! Also, we talk to an organizer of the Atlanta #standupforscience2025 about his experience 🧪

Cool paper from the Davis lab using human tonsil organoids to study CD4 and CD8 Tregs. Even though subjects with autoimmunity were excluded, organoids derived from female donors had higher autoreactivity, providing an ex vivo system to study sex differences in response to self antigens. #ImmunoSky 🧪

My weekend with immunologists devising new strategies to treat cancer, allergy, Alzheimer’s, autoimmunity and infection. The WH has just paused peer-reviewed NIH funding that pays for these studies. If you care about human life, write your representatives. Demand that NIH funding is restored asap.

Per an NIH source:

“Discussions with colleagues have suggested that if the universities all come together and raise hell about the delays to funding caused by not holding meetings, that might move the needle. From every state. There are well-funded universities in red states that will be impacted.”
