New human ovaroid model offers insight into infertility and differences in sex development

A new model of tiny human ovary organoids, or ovaroids, has been developed from stem cells, according to research presented at the first Joint Congress between the European Society of Paediatric Endocrinology (ESPE) and the European Society of Endocrinology (ESE).

Eating avocado in pregnancy cuts infant food allergy risk by nearly half

Pregnant women who ate avocado were significantly less likely to have children with food allergies at 12 months of age. The association held even after adjusting for maternal diet quality, lifestyle, and perinatal factors in a large Finnish cohort.

Developing heart cells use "speed dating" to find the right match

In developing hearts, cells shuffle around, bumping into each other to find their place, and the stakes are high: pairing with the wrong cell could mean the difference between a beating heart and one that falters.
