How sheep are helping human pregnancies

    The growth and development of a human fetus is difficult to study, both practically and ethically, as I am sure you can imagine. A new review article published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored how sheep have helped solve this problem as fetal sheep share similar brain, lung and cardiac development and placental physiology with humans, many aspects of which differ from […]

Maternal obesity resistance may protect fetus

      Research has shown that high fat diets ingested during pregnancy can impair development of the fetus as well as the placenta. The problem is that these perturbations to normal development can have life-long consequences. A new study published in Physiological Reports was interested in whether the volume of amniotic fluid can change with a high fat diet even when the mother does not develop obesity. To examine this, […]

Frigatebirds and lambs

I was checking out the award-winning American Physiological Society’s I Spy Physiology blog and came across a couple of really interesting posts about animals: “If Only Birds Could Compete in the Summer Games” This post reported a study of how frigatebirds manage to sleep during flights out at sea that can last for weeks. By measuring brain activity, the research team found that the birds were capable of actual sleep, during which time both […]
