Sunfish are the world's largest bony fish species – and yet scientists know little about their lives. This week, Our Changing World meets a sunfish researcher unravelling mola mysteries and dives into the weird world of sunfishes as a museum specimen is examined and prepared.
Sunfish are weird. They don't have a tail, they can grow massive (up to 2.7 tonnes), and we don't know much about their lives. This week, Our Changing World meets a scientist unravelling a mola mystery and watches a sunfish be prepared for 'eternal life' as a museum specimen.
EBB 244: Evidence on Artificial Rupture of Membranes, Assisted Vaginal Delivery, and Internal Monitoring. We are so excited to announce the upcoming release of a new Evidence Based Birth(R) Pocket Guide, all about Interventions! To give you a sneak peek to the Invention Pocket Guide, we are diving into the research and evidence on artificial rupture of membranes, assisted vaginal delivery an internal monitoring. Content note: Discussion of the benefits and risks of these interventions, including forceps and vacuum-assisted deliveries, which can be associated with birthing trauma for birthing people and babies, as well as the risk of mortality.
