As they swim jellyfish make a pocket of high-pressure water under their bell, which serves as a kind of wall to push off to help them swim faster Source: https://www.newscientist.com/article/2264056-jellyfish-push-off-a-pocket-of-water-under-their-bell-to-swim-faster/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

We may finally have figured out which group of animals evolved first
Biologists have argued for more than 10 years over which animal group is the oldest, but a new analysis points the finger at the jellyfish-like ctenophores Source: https://www.newscientist.com/article/2259171-we-may-finally-have-figured-out-which-group-of-animals-evolved-first/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Electric! Astronomers find sprites in Jupiter’s atmosphere
Scientists with NASA’s Juno mission say they have detected sprites or elves – electrical phenomena above thunderstorms on Earth – in the clouds of Jupiter for the first time. Unlike the red-colored earthly ones however, the Jovian ones are blue. Source: https://earthsky.org/space/sprites-or-elves-in-jupiters-atmosphere-lightning-juno…
The magnetic fields of a jellyfish galaxy
New work reveals the intricate relationship between so-called jellyfish galaxies, and the magnetic environment through which they move. Source: https://earthsky.org/space/magnetic-fields-jellyfish-galaxy-jo206…
The magnetic fields of the jellyfish galaxy JO206
An international team of astronomers has gained new insights into the physical conditions prevailing in the gas tail of so-called jellyfish galaxies. They are particularly interested in the parameters that lead to the formation of new stars in the tail outside the galaxy disk. They analyzed, for example, the strength and orientation of the magnetic fields in the galaxy JO206. Source:…

Freeze-dried jellyfish could help us grow new human skin
The bell of an upside-down jellyfish has structures that can provide a scaffolding for growing human skin cells, which could be used to help repair wounds after surgery or a bad burn Source: https://www.newscientist.com/article/2236100-freeze-dried-jellyfish-could-help-us-grow-new-human-skin/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Scientists Find the First-Ever Animal That Doesn’t Need Oxygen To Survive
Scientists from Tel Aviv University in Israel discovered that a salmon parasite called Henneguya salminicola doesn’t have a mitochondrial genome — the first multicellular organism known to have this absence. That means it doesn’t breathe; in fact, it lives its life completely free of oxygen dependency. ScienceAlert reports: It’s a cnidarian, belonging to the same phylum as corals, jellyfish and anemones….
