Exomoons around migrant hot Jupiters could hold onto life-giving atmospheres and maintain surface oceans for billions and billions of years. This is the conclusion of a paper from the University of Washington modeling the impact of inward migrating gas giants on their frozen moons. According Lehmer et al, moons around migrant hot Jupiters could hold onto atmospheres for billions of years. Image credit: NASA / JPL-Caltech. Exomoons are of increasing...

Most previous attempts at creating a womb-like device used artificial pumps to drive the blood through the system, causing heart failure. In the system invented by Partridge et al, the fetal heart is the only pump. It is different in other key ways. Use of the bag, rather than a more open container, nearly eliminated the infection issues that contributed to previous failures. And while previous attempts relied on blood vessels in the neck, the authors figured out how to quickly and successfully insert tubes (cannulas) into the notoriously touchy umbilical vessels.
