`Ozone layer: Concern grows over threat from replacement chemicals' LINK
`Substances used for air conditioning in almost all new cars are building up in the environment and may pose a threat to human health, researchers say. These "ozone friendly" chemicals have been introduced to replace products that were damaging the ozone layer. Now widely used across industry, these alternatives do not break down in the environment. Scientists have now found increasing levels of these chemicals in Arctic ice samples dating back to the 1990s..'.

`....Canadian researchers, studying ice samples from the Arctic dating back to the 1990s, have found "dramatically" increasing levels of ozone replacements called short chain perfluoroalkyl carboxylic acids (scPFCAs). "We're seeing much, much larger levels, on the order of 10 times higher now than we saw before the Montreal Protocol," said Prof Cora Young, from York University in Toronto, the study's corresponding author. "We don't know a lot about them and their potential toxicity, but we do know that we are committing the environment to a great deal of contamination."

"single-domain, ferromagnetic crystals."
I wonder if I have them as well.
Freon replacement. I thought we'd solved that one Tiz, apparently not. We do complicate things don't we. Perhaps it's time to go back to ammonia!

Firstly on the Ozone friendly bit, yes noted there is a build up, but any adverse effect seems unknown at the present time. It would make sense for refridgerants inc vehicle and building air conditioning, that incident damage aside, closed loop recycling needs to be carried out, and this must be done freely arranged by local authorities, I see too many fridges dumped, with the copper piping cut for the small man to take a few bits to make some money, this must stop.

On the magnetism, if most cells are essentially electro-magnetic with internal electron bonds there would be no need as such for the Fe element for sensory requirements, presumbly the Fe enhances the response, at bit like a transformer in an electrical circuit.

An elegant piece of research on the asteroid impact that killed off, or helped to kill off, the big* dinosaurs.

Good grief. . .

Quantum oscillation

Snake Oil. I have a piece of string that can tie up the hole in the ozone layer, sell you it for £1 million.

Tripps, you'll notice that the BBC article also refers to Glastonbury Town Council's 5G Advisory Committee. They've been in the local news here for a while now. The Committee has a preponderance of `gulllibles' who support anti-5G and anti-vax etc. Unfortunately the `normal' people on the Committee have been resigning from it and leaving the town in the hands of wierdos. Glastonbury has always been a centre for such people (think King Arthur, spiritual healers, crystal fanatics etc) but now it's getting into a dangerous stage where people are going to suffer harm through thinking they are invulnerable because of the things promoted by the wierdos. It worries me too that this sort of behaviour is beginning to spread well beyond Glastonbury and is accelerated by the current tide of populism.

Included in the cranks is one James Dyson in my book. He is regarded as an ingenious self made man, (on the rich list no less). He, like the Snake Oil salesmen and magic crystal sellers has made his money on pseudo science gadgets with no proven substance in the real world of physics. He sells those to thousands of gullible people as well.

Why does my mind fly to P T Barnum? "There's one born every minute!".

Here's something based on scientific evidence which is going to prove very useful as it gets to a commercial stage...
`The little lights now packing a deadly punch' LINK
"The tech we are working on could transform water sanitisation techniques and offer access to clean drinking water to even remote developing regions via portable systems," says Christian Zollner from the University of California in Santa Barbara. Mr Zollner has been working on light emitting diodes (LEDs), the long-lasting technology in modern lightbulbs. They are probably in the lightbulbs in your house, or the headlamps of your car. Because they are tough and energy efficient, researchers are always trying to find new ways of using them. Mr Zollner and his team have been working on LEDs that emit ultraviolet light, in particular UV-C light, which is deadly to bacteria and viruses, including the coronavirus. His goal is to make those LEDs more powerful, robust and cheaper. "Right now, UV LEDs are capable of a few milliwatts of power. Our aim is to make them 10 to 20 times more powerful. "Our focus previously was mainly on using them for water sterilisation, but the Covid-19 pandemic has made us realise there is also a big market for sanitising surfaces and equipment. If there is another virus situation in say five or 10 years, this technology could be very useful."

I knew about the power of Ultra Violent light Tiz but not the LEDs. Wonderful technology, more power to their elbow!
That water bottle is a miracle!
I remember many years ago discovering that Johnson and Johnson insisting that sub contractors who packed sterile fabric products using tables with black Formica tops as they said they were the most sterile. Never really understood that. We automatically associate white with clean but that's not necessarily the case.

Head lamps have been killing bugs for a long time

Some of the early LEDs produced an excessive amount of Ultraviolet that they presented a danger to eyesight. Mainly used in agriculture for extending daylight hours at a low cost.

I used to work with a bloke who loved malapropisms and he converted me to 'ultra-violent' light, so much more descriptive! He talked about insulting tape and non-ferocious metals as well.

Ah, so that's why there's a decline in insect life, and there was me thinking it was due to pesticides!

Elon Musk and Space-X. Quite amazing, especially the first stage landing automatically on the ship for recovery and re-use. Imagine standing on the deck watching it come in and wondering how good the calculations were!

Better resolution...but more clutter `up there'....
`Planet's satellites aim for still sharper view of Earth' LINK

Quite amazing isn't it.....

Makes one wonder why these people are putting all this money into just getting better pictures or even better internet coverage. Its said that the more advanced countries know more about the mineral potential of the poor countries than than those countries themselves. Then we see the US offering up satellite pictures of the traffic flow round hospital in China. They could probably know more about our own economy than we do.

In some ways the more you know they less influence you have to change things

I noted that one of the factors in the search for information about just when Covid started in China is analysis of the traffic round hospitals and the number of cars in the car park.

It's unwise - I have learned over the last few years - with the rise of the internet as a means of getting news, to rely on anything which involves a photograph.

I looked at the photos, and my first thought was - is it that simple, what does that prove? There are organisations from all sides who wish to influence our thinking. Perhaps one photo was taken at weekend, and another during a busier weekday?

Stay sceptical. . . . .

With regard to the photos of Chinese hospitals, China's leaders have pointed out the same concerns as Tripps notes. It's easy to make up a story these days! (Although there's a lot going on in and around China that those leaders deny but I believe, such as the military islands in the South China Sea.)

You're right David....
