Breast milk contains urea. Researchers think it may play an unexpected role

Researchers found that urea concentrations in breast milk change during lactation, with evidence suggesting that the mammary gland regulates its transport independently of measured maternal dietary and blood urea levels. Laboratory experiments showed that different urea concentrations favored the growth of different bacterial strains, suggesting a possible role in shaping the infant gut microbiome and raising questions about the composition of infant formula.

Could a single brain scan reveal how quickly your body is aging?

Researchers examined whether DunedinPACNI, an MRI-derived measure of brain aging, was associated with blood-based indicators of biological aging in 746 adults across two independent midlife cohorts. Faster DunedinPACNI was associated with higher levels of multisystem biological aging in both cohorts and greater changes in aging-related blood biomarkers over 7–15 years in a longitudinal subgroup of 224 participants.

Five AI models tackled 227 pharmacy exam questions. Here's where they struggled

Researchers evaluated five large language models using 227 infectious disease-related pharmacy examination questions and found that all achieved approximately 90% accuracy, with ChatGPT-4o-mini scoring highest at 91.2%. Accuracy was significantly lower for medicinal chemistry, clinical microbiology, higher-order cognitive questions, and image-containing questions, raising concerns about relying on AI-generated answers without independent verification.
