New picture of Uranus by James Webb:

Yes, it has rings. But very faint (not continuous), so for a long time it was believed that there were none. On this image they are unusually clear, perhaps that has something to do with mr. Webb focusing on the infrared spectre.

One more thing: Rotation axis of Uranus is unusual, "tilted sideways, nearly into the plane of its solar orbit. Therefore, its north and south poles lie where most other planets have their equators." (Wikipedia). Which is why you on this picture, unlike pictures of Saturn, can see the whole ring system.

Yes, I knew a little bit about this planet, but that the ring was looking like in that short video was new to me.
Back in the 80s, when I was at school, I was in a special study group - I don't remember he right English word for that - consisting of pupils who were interested in astronomy.
I even had such a ... dial ? ... or how it is caled, to find out positions of stars and of star constellations ...
That teacher - he died a few years ago, unfortunately, was also the very first person who goit me interested in Stonehenge. Back then, THAT book was brandnew ! Stonehende as an observatorium ! Alinged towards stars ! That was a breathtaking new idea, then ! I think the author's second name was Thom.
I prepared an article on that for the school's "newspaper", but due to an misunderstanding it sadly never got printed.
Stonehenge, however, dsince thewn, had alreays remaine dear to my heart. You cannot imagine it how wonderful it was for me last year to see all these magazine reports and exhibition catalogues about Stonehenge !

And : Because brains are so much essential in living beings, this kind of signal functionality must've been developed relatively early in evolution history.

Next interesing question would be : How do plants communicate within themselves ?

Not necessarily. So far, as I understand the article, the signals are found in the cerebral cortex, which is a fairly recent development of the nervous system, and only mammals have it.

I see. Hm, I had thought that it would have been there earlier, so to say.

For all I know it may be found in older parts of the brain, eventually. But at the moment it has been found in the cortex, and that's a recently developed structure. I suppose there will be a lot of further studies based on this find.

pibbuR who will examine the article carefully, seek other references and then maybe come back to the watch with more info.

PS. The oldest part of the brain and what is fundamentally necessary for life is in the medulla oblongata at the base of the brain. Here you find centers for handling respiration and circulation. Even small injuries in this area are incompatible with life. OTOH you can destroy most|all of the cortex (decerebration) and still live - sort of. Without consciousness, sensory experience, voluntary movements, in short any higher brain functions which is what makes us human. DS.

A new and more likely theory on the initial formation of amino acids, the organic compounds that make up proteins when they are chained together.


The article and its gory (or pre-gory) details: https://www.mdpi.com/2075-1729/13/5/1103

PS: But who made the ribosomes?

EDIT: Should we move this to the kickstarter subforum?

Good old Europe
Fascinating it can also be the cause of killing all life as well.
