a large geomagnetic storm is creating dazzling aurorae in both N and S hemispheres
these are from Tassie, last night

Spectacular southern lights seen across Tasmania after ‘extreme’ solar storm
The best time to see the aurora was from 10pm Saturday to 2am Sunday…

Certainly a spectacular light show. More pictures in this story. There will be another opportunity to see the lights this evening (Sunday 12th)

It has also
As a side effect, GPS signals were a tad intermittent here in USA during the flares.
Driving from Fresno CA to Death Valley the other day the gps kept going on and off.
Lucky we had some old style paper maths.

The search for Planet 9 continues.

'It just has to be out there': Why scientists are still searching for Planet Nine
In 2016, astronomers published a study suggesting a ninth planet could be hiding on the edge of our Solar System. Eight years later, they're still looking for it. So what will it take to find it?

What have scientists found at the bottom of the oceans? Apart from SPAM, radioactive waste and baby bottles.
Interesting stuff here. The discovery of a teeming eco system around the cracks in the ocean floor where magna hots seawater is a great start.

Radioactive waste, baby bottles and Spam: the deep ocean has become a dumping ground
The long read: The ocean’s depths are not some remote alien realm, but are in fact intimately entangled with every other part of the planet. We should treat them that way

Looks like the SR-72, has actually been deveolped to replace the ageing and retired SR-71 Blackbird.
It has a turbine/scram jet combo, niiice.
If they have annonced this to the public, what are they working on know?
Lockheed Martin has also said that it has plans to test-fly the aircraft in 2025, with entry into service in 2023. In the latest available public information offered about the SR-72, Lockheed revealed that the aircraft would be unmanned.

This story piqued my interest. A modern day science collaboration to identify the precious genetic components of wheat strains collected over a 100 years ago. The money shot is that these strains will enable 21st Century farming to feed people in a far warmer climate.
Much more detail in the story. Well worth a full read

A hundred years ago, the plant scientist Arthur Watkins launched a remarkable project. He began collecting samples of wheat from all over the globe, nagging consuls and business agents across the British empire and beyond to supply him with grain from local markets.
His persistence was exceptional and, a century later, it is about to reap dramatic results. A UK-Chinese collaboration has sequenced the DNA of all the 827 kinds of wheat, assembled by Watkins, that have been nurtured at the John Innes Centre near Norwich for most of the past century.
In doing so, scientists have created a genetic goldmine by pinpointing previously unknown genes that are now being used to create hardy varieties with improved yields that could help feed Earth’s swelling population.
Strains are now being developed that include wheat which is able to grow in salty soil, while researchers at Punjab Agricultural University are working to improve disease resistance from seeds that they received from the John Innes Centre. Other strains include those that would reduce the need for nitrogen fertilisers, the manufacture of which is a major source of carbon emissions.
“Essentially we have uncovered a goldmine,” said Simon Griffiths, a geneticist at the John Innes Centre and one of the project’s leaders.
“This is going to make an enormous difference to our ability to feed the world as it gets hotter and agriculture comes under increasing climatic strain.”

'Superlubricious' coating radically drops friction between metal parts
I came across this story recently. Very, very interesting. Could have a very profound effect on scores of industries. The technology to produce this super lubricant seems cheap and simple to apply.
'Superlubricious' coating radically drops friction between metal parts
Using biowaste from cassava plants, scientists have created a coating that virtually eliminates friction in metal parts. The breakthrough has the potential to deliver better fuel economy, extend the lifespan of moving parts, and deliver enormous savings in myriad industries.

Check out the experimental research paper if you are interested into getting into the weeds on this technology. The other very clever part if this process was using cassava biowaste as the carbon source for this process.'Superlubricious' coating radically drops friction between metal parts

If it works out it could be a good prospect.
But if it was easy it would have already been done obviously there were issues to overcome.

Nuclear is not easy but i know India had started that process too.
None of the key western countries have any interest there as they do nuclear first for the nuke weapons, and nearly always under gov agencies or in close link with.
No theory or technological challenges compared to plutonium, just need to build the whole design and production chain from scratch.

For the differences

Not as efficient as plutonium, if you do not care about wastes and risks, Uranium is better
Don't believe the spin on thorium being a greener nuclear option

Ecologist Dr Grey Coupland sees huge potential in the rise of 'tiny forests' and is championing their development in Perth.
The pocket forests are grown using the Miyawaki method, created by Japanese botanist Akira Miyawaki in the 1970s.

This article looks at how Miyawaki forests have taken off in the US. The You Tube story is eyeopening.

Miyawaki: A little forest with a towering task (video)
A Japanese method of planting fast-growing native forests is spreading worldwide. How it brings “grounded hope” to one of its U.S. practitioners, and nurtures a sense of community around its sites.
