The new president says he wants to "get toxins out of the environment" and "keep our children healthy," but many of his administration's actions are doing the opposite. We bring the receipts.

New on the PRHE blog: a study of 800,000 California births finds that living near industrial animal farms (CAFOs) during pregnancy is linked to higher risk of preterm birth — with wind direction playing a key role.

Fertility rates have declined. Preterm birth and miscarriage rates have risen. Climate-related exposures may be an underrecognized factor — and AI's growing energy demands could make things worse. New blog post by Dr. Anna Claire Fernández. ⬇️

Save the date! PRHE partner @UCSF_EaRTH is hosting a webinar on Weds, Aug 19 at 11 AM PT with Dr. Stephanie Gaw on how wildfire smoke exposure may affect placental function & what multi-omic research is revealing about maternal & fetal health. Register at earth.ucsf.edu/events
Wildfire smoke isn't just a West Coast problem anymore — and for pregnant people, the risks go beyond breathing difficulties. PRHE Acting Director Dr. Amy Padula shares what the science tells us and what you can do.

A new PRHE study published in @JExpSciEnvEpi shows that social conditions — like poverty, discrimination, and limited healthcare access — can compound the harm of chemical exposures.

Dr. Jessica Trowbridge, Associate Research Scientist at PRHE and a breast cancer survivor, testified today with @BCPPartners on the Safer Food Packaging Act (AB 1148) at a CA State Assembly Health Committee hearing. Great job, Dr. Trowbridge!
Did you know tire wear is one of the biggest sources of microplastics in our waterways? A new study found that fish and shrimp eat these tiny rubber particles — and it's stunting their growth and altering behavior in ways that ripple up the food chain.

New research from our team @ucsf sheds light on the prenatal environment. Scientists examined amniotic fluid and confirmed 10 environmental contaminants, 9 of which had never previously been detected. Read more about it in our new blog post.

PRHE correspondent Ari Eastburn is in Sac today for the Fund California Science rally—where scientists, clinicians, and more are calling for funding for life-saving research. Ari says: “Everyone here has a story about their loss of funding.” 🔬 #SaveScienceSaveLives
This #InternationalWorkersDay, we stand with every worker who deserves better protections from chemical exposures — and all other hazards — in the workplace. We also stand for the right to organize and thank every person who makes their voice heard on #MayDay2026. 💪
Congratulations to our long-time collaborator @RachelFrosch on becoming the first-ever associate provost for energy, climate, and environment @UCBerkeley! We're so proud to see her work recognized at this level. 🌱

PRHE is back in action! Our staff gathered this week for a strategic planning retreat — coming together to reflect, align, and map out what's next. Big things are on the horizon. 🔭
New blog post: A major study of 20,000+ pregnancies found that wildfire smoke exposure — especially multi-day smoke events — is linked to increased risk of preterm birth. Timing during pregnancy matters too.
