Climate and Weather at 3 Degrees More
The Earth is heating up and there is more than enough science to prove this, as a result the climate is changing. We were advised by the science to avoid a 1.5 degree rise in temperatures, which we have FAILED to do. Now this is what may happen if we fail the next step.

Cosmic Concepts: Infrared Light
I found this on the Fediverse, posted by the Space Telescope Science institute, a 3 minute (ish) introduction to Infra Red (IR) Light. Presented by Dr Frank Summers.

Microbes found to destroy certain 'forever chemicals'
The subject of 'so called' forever chemicals hit the headlines from time to time, new research indicates that microbes can perhaps play a part in how to deal with these, other than trying to not produce them in the first place of course.
You can read the article on Science Daily. A direct link can be found here
There is also a related article on dealing with Forever chemicals here

What Is Symmetry in Physics?
What Is Symmetry in Physics?
A short article published on Science Daily explaining what symmetry is in Physics.
Understanding symmetries and broken symmetries is important for understanding the physical properties of matter and our universe.
Hopefully this is useful and or interesting to readers.

An evaluation of reproducibility
An evaluation of reproducibility and errors in published sample size calculations performed using G*Power
Another article link found on the Fediverse, this will possibly be of interest to those involved in research.
**Quoted objective (or part thereof) from the research. **
Objective. We aimed to (1) estimate how many published articles report using the G*Power sample size calculation software; (2) assess whether these calculations are reproducible and (3) error-free; and (4) assess how often these calculations use G*Power's default option for mixed-design ANOVAs; which can be misleading and output sample sizes that are too small for a researcher's intended purpose. Method.

Space Bricks from meteorite dust
LEGO creates 'space bricks' made from meteorite dust – Physics World
Interesting article from Physics world, on a possible construction solution for bases on the Moon. Lego and a team of scientists from the ESA have created bricks from material from a crushed meteorite and a few other materials
I have started a Fediverse thread on this topic to ask if this technology could perhaps be combined with Boron Nitride in order to provide extra space radiation shielding.

Ariane 6 launch
ESA – Ariane 6 launch: how to watch and what to look out for
The European space agencies new Ariane 6 rocket is scheduled for its inaugural launch on July 9th. This is a great step forward with a new rocket to usher in a new era
You can read more about the launch here
The following infographic is just embedded from the ESA website for illustration.

Astro events
Over the summer, there is going to be a significant astronomical event. that will take place in the constellation of Corona Borealis. The event is in fact a nova, and not a supernova. I asked on the Fediverse to clarity what is going to happen.
Just making this post so I can also share some related links to help clarify the difference between the various types of Nova event.

Handbook of X-ray and Gamma-ray Astrophysics
This was posted to the Fediverse earlier today, I replied to the post with a link to the resource [1]. As mentioned, there are a good few papers on arXiv [2]
This is a great way to bring together related resources so they can be found quickly and easily.

Potential Ozone Depletion From Satellite Demise
Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations
Interesting paper that was published in Geophysical research letters looking at potential damage to the Ozone layer from Satellites re-entering the Earths atmosphere and burning up. The specific issue seems to be related to the Aluminium Oxidizing, and then this travels down to the Ozone layer and causes a chemical reaction.
Give the number of Satellites in orbit and the importance of the Already fragile Ozone layer, this is not good news.
You can read the research here
There is a Fediverse discussion here that is quite interesting, I have also started a Science Forums discussion
