Antibiotics for C-sections Effective After Umbilical Cord Clamped
Antibiotics for cesarean section births are just as effective when they’re given after the umbilical cord is clamped as before clamping – the current practice – and could benefit newborns’ developing microbiomes, according to Rutgers co-authored research. The study, by far the largest of its kind and published in the journal Antimicrobial Resistance & Infection Control, challenges current recommendations for antibiotic use. Administering antibiotics after clamping does not increase the risk of infection at the site of C-section incisions, the study concludes.

Study Provides First Evidence of a Relationship between a Bird’s Gut and its Brain
A study of the relationships between cognition and the gut microbiome of captive zebra finches showed that their gut microbiome characteristics were related to performance on a cognitive assay where they learned a novel foraging technique. Researchers also identified potentially critical bacteria that were relatively more abundant in birds that performed better on this assay. This correlation provides some of the first evidence of a relationship between a bird’s gut microbiome and its brain.
