STEM Group 12/8/2023
The next stem group will be on Saturday 12th August 2023, 11am to 15:00. But will be slightly different.
Due to a Fun Family Festival taking place, which I am helping with as it also ties in nicely with the STEM group. I am planning an activity around:-
As a result, IT LEARNING CENTRE WILL BE CLOSED
For information contact Paignton Library directly with regard to any questions about this.
Next STEM group
The next STEM group event will take place on the 9th September in room 12 only.

Home Chemistry 18
I have had another go at growing salt crystals. This time I dissolved a quantity of pure Sodium Chloride (NaCl) in to water using a conical flask, then poured this solution in to a glass dish and left for about 2/3 weeks.
Eventually all the water evaporated away, leaving crystals behind. Using my USB microscope, I found and took a picture of some that had grown in to a nice cube shape.
Update 29/7/2023
I have taken another photo using the USB Microscope and also included the calibration / measurement sheet in the photo to try and illustrate crystal size.
Please see Mastodon post for details.

As a result, I won't be in the IT suite and therefore will not be able to help with any IT / Computing related activities or DEAL with any problems that arise.

Next STEM group
- The next STEM group event will take place on Saturday 9th September.
- Code club will run as normal on the 19th August (3rd Saturday)

Diverse organic-mineral associations in Jezero crater, Mars
The rover that just keeps giving, so looks like “NASA's Perseverance Mars rover discovers more evidence of building blocks of life on Mars.”.
This is from the original Fediverse post by Natalie Davis
NASA's Perseverance Mars rover discovers more evidence of building blocks of life on Mars. Although the organic molecules were not necessarily the products of biological processes, it does raise the chances Mars once had life and could indicate we're looking in the right place.
So exciting stuff, the full article in Nature can be found here
So we are finding more evidence Mars may once have had life. If you want to learn more about some of the basic building blocks of life and how we go about finding these, please check a previous post about the Mumbai University Astrobiology course videos
In the mean time feel free to ask on Fedi or on Science forums.

There were two big bangs
This new theory is fast gaining ground, the idea being that the current theory only produced 5% of the matter we can see, where as the universe is made up of 95% dark energy and dark matter. So this had to come from somewhere. The idea now is there was a secondary big bang producing the remaining 95% of this matter.

Left and Right handed molecules
Some interesting research has taken place and there is now a better explanation of why we have right and left handed molecules.
The article Breakthrough’ could explain why life molecules are left- or right-handed was published on Science.org and shared on the Fediverse.
I have asked a question about this and also how cis & trans molecules are also created. even though this is referred to as stereoisomerism, so a different topic area.
Papers & articles
I would suggest reading in the context of the above article, as they are all linked from that.

JWST finds water on Enceladus
Posted to the Fediverse on 30/5/2023. The James Webb Space Telescope has potentially found water on Enceladus, one of the moons of Saturn. This is a great discovery and shows there is water on other planets. You can read original fediverse post via link below.
The following graphic was also part of the post, so reproducing here too.
Feel free to discuss further either tag me on fedi @[email protected]. Or you can start a thread on Science Forums
Sorry, I don't use mainstream social media. This is 2023, the fediverse provides intellectual content.

Physicists suggest that black holes could have an exit to other places in the universe
Interesting article from Meson Stars regarding black holes having possible exits. I have included a paste of my Fediverse comment below. However feel free to discuss on Fediverse or on Science forums.

Comment
This does make some sense, I have heard about white holes, which are the opposite of black holes as they allow matter to be ejected in to space. This seems to tie in with the suggestion in the article that if you could pass through you cannot get back again. However in relation to this
"Scientists have already said that all matter inside a black hole is destroyed, "
I got the impression matter can't be created or destroyed, it is interchangeable with energy. In which case, could it be that matter is drawn in to a black hole, somehow converted in to energy then ejected from a white hole?
So purely on a speculative idea
So how do we find these white holes, perhaps we have already found them as we can detect things like gamma ray bursts or neutrino emissions but can't always explain them, perhaps these are related to white holes and we are observing the release of energy in to space as these or similar phenomenon

Saturn Moon count Jumps
This was posted to Fedi on 19th May. New Scientist report on the moons around Saturn thanks to new research in to the rings. We are now up to 140, which surpasses the moons around Jupiter.

Climate Change
Report in nature, that Top climate scientists are sceptical that nations will rein in global warming. I think these warnings are really plausible, as we have seen much higher than average temperatures this winter, well above this 1.5 degree rise we are meant to be avoiding.
The fact so many scientists don't think we are going to even meet these targets is also worrying.
This was posted to the Fediverse I commented to make the point about higher than normal temperatures.
We are really in trouble and need to wake up.
