Which came first: the reptile or the egg?

Researchers from Nanjing University and University of Bristol found that early reptiles, birds, and mammals may have borne live young, contrary to the long-held assumption that hard-shelled eggs were key to their success. Extended embryo retention was likely a crucial adaptation that allowed these animals to thrive on land.

Fertility treatment does not adversely affect cardiovascular health of offspring, international study suggests

A large international study found no robust difference in blood pressure, heart rate, lipids, and glucose measurements between children conceived naturally and those conceived using assisted reproductive technologies. Children conceived via ART had slightly higher cholesterol levels in childhood, which did not persist to adulthood.
