Interrupted-time-series analysis of the immediate impact of COVID-19 mitigation measures on preterm birth in China
The broader impacts of COVID-19 mitigation measures may include changes in the incidence of preterm birth. Here, the authors use data from ~11.7 million pregnancies in China and find evidence of a small decline in preterm birth rates immediately following the implementation of COVID-19 mitigation measures.

A key genetic factor for fucosyllactose utilization affects infant gut microbiota development
The factors shaping the development of infants' gut microbiota are poorly understood. Here, the authors show that alterations in gut microbiota development in infants are associated with the presence of bifidobacteria having a gene for utilisation of human milk oligosaccharides.

Neural dynamics of prediction and surprise in infants
Prior expectations shape neural processing in the brain and violations of these expectations can have a profound influence on learning. Here the authors demonstrate that such predictive coding mechanisms are already functional in the brains of 12-month-old infants.

Maternal bile acid transporter deficiency promotes neonatal demise
The mechanisms underlying perinatal mortality due to intrahepatic cholestasis of pregnancy are not fully understood. Here, the authors show that absence of the nuclear receptor and bile acid regulator Nrli2 and the biliary transporter Abcb11 strongly reduces maternal serum bile acid levels, improving neonatal survival.

Editing the genome to introduce a beneficial naturally occurring mutation associated with increased fetal globin
Adult expression of fetal haemoglobin is beneficial and thus desirable in patients with haemoglobin disorders. Here the authors introduce a naturally occurring mutation in the γ-globinpromoter and show that it causes binding of an activator TAL1, chromosome looping and revival of fetal haemoglobin expression in erythroid cells.

Trained immunity in newborn infants of HBV-infected mothers
The ability to fight infections matures after birth and is thus termed ‘trained immunity’. Here the authors show that cord blood cells from hepatitis B virus-infected mothers respond more strongly to bacterial infections, suggesting that viral exposure in uteropromotes trained immunity in newborns.

Genome-wide association study identifies a new susceptibility locus for cleft lip with or without a cleft palate
Cleft lip is one of the most common congenital birth defects with substantial impairments to quality of life. Here, Sun et al. identify a new locus associated with cleft lip in diverse Chinese populations.

Mybpc3 gene therapy for neonatal cardiomyopathy enables long-term disease prevention in mice
Hereditary hypertrophic cardiomyopathy (HCM) is caused by mutations in cardiomyocyte genes, such as MYBPC3. Here, the authors use virus-mediated gene therapy to correct Mycbpc3mutations in 1-day-old mice and, by administering just a single dose, prevent development of HCM over a period of 34 weeks.
