Maternal BMI predicts the risk of neonatal hypoglycaemia independently from maternal obesity suggesting that the link between maternal adiposity and neonatal hypoglycaemia is complex. Identifying the u...

In Brief: The authors conducted genome sequencing on 151 mother–father–offspring trios from 68 vertebrate animal species in order to estimate and compare germline mutation rates (GMRs). They found a 40-fold variation in GMR per generation between the species. Higher GMRs were observed in species that have a longer generation time, older age at puberty and fewer offspring per generation.Comment: Mutations in germline DNA during gametogenesis are...
