Covid 19 Origins
One of the early theories about Covid 19, was that it originated in a Wuhan market, where humans and animals were in close contact.
Recent research seems to have confirmed this. There are several mainstream media (newspaper) articles on this. I decided to try and find a more useful source. so this article on Web MD seems a good initial source.
I think the above articles are also peer reviewed, so they are a more credible source, plus it is far better to read the original articles / papers than news paper reports which end up inaccurate, if the Journalist is not a specialist or just in some case lazy and sloppy.
The sense about science website has some good information and advise with regard to asking for evidence for research purposes. Along with this is an excellent introduction to the peer review process, so well worth reading.
It is good, that we are finally seeing the results of actual research in to this, and while it probably won't put conspiracy theories to bed, it may influence policies etc that are hopefully based on researched based evidence.

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.

Positive note: Despite the current situation in Ukraine, those involved in science can still carry on working and collaborating, for the benefit of everyone.

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.

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
