Online reference library provides a more accurate picture of drug exposure

Doctors and researchers try to understand what medications a person has taken by asking patients directly or by looking at medical records. But this information is often incomplete.

Everyday PFAS exposure alters placental function in early pregnancy

This study measured real-life PFAS concentrations in first-trimester human placentas and used these data to create a pregnancy-relevant PFAS mixture. In 3D trophoblast spheroid models, the mixture altered invasion, hormone secretion, and gene expression without broadly reducing viability at environmentally relevant doses.

Industrial and farm chemicals quietly alter the balance of gut microbes

This study systematically screened over 1,000 agricultural and industrial chemicals and found that many can inhibit human gut bacteria in vitro. Beyond antimicrobial effects, these chemicals act as selective pressures that can reshape microbial competition, tolerance mechanisms, and metabolic pathways.

Modern pollutants and ancient genetic variants could explain why some women develop endometriosis

A new study suggests that certain genetic differences, passed down from ancient human ancestors, and exposure to common present-day chemicals could explain why some women are more likely to develop endometriosis.

Higher PFAS levels reduce blood sugar improvements after teen bariatric surgery

A new USC study shows teens with higher blood levels of per- and polyfluoroalkyl substances (PFAS) measured before bariatric surgery had smaller improvements in blood sugar over five years, including fasting glucose and hemoglobin A1c (HbA1c), which measures average blood sugar levels over the past 60-90 days.

Study links endocrine-disrupting chemicals to hidradenitis suppurativa

A Johns Hopkins Medicine study involving a dozen people with the inflammatory skin disease hidradenitis suppurativa (HS), which mostly affects skin folds, is believed to be the first to provide evidence that hormone-disrupting chemicals commonly found in ultra-processed food and single-use water bottles may contribute to the development of or worsen the condition in some people.

Experts call for bold policies to curb the health harms of ultra-processed foods

The increase of UPFs in diets worldwide presents an urgent challenge to health that demands coordinated policies and advocacy action to address, says a new three paper Series authored by 43 global experts and published in The Lancet. The Series exposes the tactics UPF companies use to drive consumption and prevent effective policy.
