Effect of long term space flight on the Brain
Study explores effects of extended spaceflight on brain
Scientists from the U.S., Europe and Russia are part of a team releasing the results of a large collaborative study involving the effects of long duration spaceflight on the brain.

Hubble from Space and Integral-field Spectroscopy
*Hubble from Space and Integral-field Spectroscopy from the Ground: Seeing Both the Forests and the Trees
This is the Space Telescope Science Institute Lecture from March 2022.
A detailed, but also beginner friendly, in parts, introduction to spectroscopy also looking how this is applied and used in Astronomy.

LibreAdventure Testing 3
LibreAdventure Testing 3
Lots of work behind the scenes to iron out some bugs & problems with the software. I was involved with further testing on 15/3 and there is further testing planned for 17/3. This testing has also included load testing so we know the server will stand up to the number of users expected.
Looking good for the weekend. There will be a LibrePlanet post on Saturday with a link to this.

A New Map of All the Particles and Forces
A New Map of All the Particles and Forces
This is an interesting new way to look at the standard model of particle physics that re-arranges things to better illustrate how different particles relate to each other.
The current diagram to present the standard model is below, this just shows the normal matter. I have one that shows anti matter too. In some ways this follows a similar layout to the periodic table
As an intermediate, diagram I actually like this diagram
Both the above diagrams are sourced from [1].
The new model called the 'double simple model' does look far more complex. However it has far more detail and better illustrates the relationship and interactions between the different forces / particles. You can view this at [1], while the paper describing how the team came up with this is at [2].
I have printed this, so it is something to discuss at the next STEM group meeting on the 12th March.
I think the paper at [2] has been around for a while, so this article is more on the Quanta Magazine article.

Getting Hydrogen out of banana peels
Getting Hydrogen out of banana peels
This is interesting, and potentially a good way to make use of waste material. I have included a few links below, and the article link is in the main links below.
It would also be interesting to figure out if a school has such a Xenon lamp, should be possible to try and reproduce this in a school lab. I would guess the Hydrogen gas could be collected if the mass was in put in say a boillng tube, with a bung, and glass tube to a collection tube, then the Hydrogen could be collected and tested for with a lighted splint, so you would listen for the 'pop' made when the Hydrogen ignites. So on a small scale it would prove that Hydrogen can be produced.
UPDATE 25/2/2022
I have found an update to this, from the Royal Society of Chemistry article here

Building a ping pong ball shooter – part 2
Building a ping pong ball shooter
Further to the previous post, the ball shooter is now built up. I do need to solder this together, at some point. For now, it works as it is. This is the test I did at the library (more space).

Building a ping pong ball shooter
Building a ping pong ball shooter
As part of an order from Better Equipped, I sent for a ping pong ball shooter. This consists of two rotating disks, which propel a ping pong ball forward.
So far, I have only partly built this. I need to do some soldering to complete. I also want to find a safe place to test it. This project will be demonstrated at the Paignton Library STEM group, but could be used in a school too. This would support, Science, Maths, Design & Technology and possibly other subjects.

Growing salt crystals – 2nd attempt
Following my previous attempt at this. I am now repeating the experiment with pure Sodium Chloride. I am also using a 250ml conical flask, which is much larger.
This time I used hot water from the kettle, taking a precaution of warming this up with warm tap water first, just in case the sudden temperature changed caused the flask to shatter. I then added Sodium Chloride powder.
I am now leaving this to hopefully grow some nice crystals which I would expect to be more of a cuboid shape. This prediction is based on:-
- Pictures of similar results
- The molecular shape of Sodium Chloride.
I am doing this for:
- Support the STEM Group events
- Hopefully can use this in a school to help children grow their own crystals.
- Personal interest
- Research purposes
