And for the fun of it:

Powerful solar storms are a nightmare for farmers. 'Our tractors acted like they were demon possessed'

When the sun's fury disrupts high-tech farming, precision turns to chaos.

We are currently in a very high solar activity year so the auroras, and impact on weather this year..but we can blame the cows farts

We are. We had a long period of very low solar activity previously, so low scientists were wonderingwhats happening. . Over 5 years.
Now is the time for a solar flare.

Indeed, statistically it should come indeed.
Like earthquake, no an exact science but odds are increasing daily.
Sadly for me:
In the last 2 years, every aurora, meteor shower, conjunction of planets, red moon, etc saw our sunny coast skies blacjenned with clouds when it was not even pouring down

I would like to go to Tazzy and really see it. Saw the edge from Melbourne but not that clear.

I've been watching Brian Cox's 'Solar System' on abc. A nice way to zip around the neighbourhood, and the CGI is good to create the worlds we'll never see (& nor will Elon)

Finally, someone explains why we all need subtitles when watching TV

No, you're probably not losing your hearing.

On 01 January 2025 at noon, Earth's axial tilt, or mean obliquity, was 23.43603° or 23°26'09.6".

Earth's mean obliquity today is about 0.00001°, or 0.04", less than 30 days ago.

The Arctic and Antarctic circles today are 1.2 m closer to the poles, and the Tropic of Cancer and Tropic of Capricorn are equally closer to the equator than 30 days ago

Interesting story on the impact of the us of lead by the Romans.
It was/is a great metal for many reasons but lead poisoning is also very real.

Roman Empire’s use of lead lowered IQ levels across Europe, study finds​

Widespread use of metal caused estimated 2- to 3-point drop in IQ for nearly 180 years of Pax Romana

Apart from sanitation, medicines, education, wine, public order, irrigation, roads, the fresh water system and public health, what did the Romans ever do for us? asks an exasperated Reg in Monty Python’s Life of Brian.
One answer, according to a new study, is widespread cognitive decline across Europe, courtesy of the vast quantities of lead pollution churned out by the booming metals industry that shaped the empire.

Researchers have said the massive expansion of mining and the processing of metal ores in particular caused airborne lead pollution to soar during the peak of the empire, leading to an estimated 2- to 3-point drop in IQ across the land.

“It’s amazing that we were able to quantify atmospheric air pollution over Europe nearly 2,000 years ago and assess potential health impacts on the ancient Roman civilisation,” said Dr Joseph McConnell at the Desert Research Institute in Nevada.

I think this is as good a thread as any for this story. Quite simple, brilliant and inspiring.
Its a model of using technology that I think should be used far more broadly.

Invention made in army Makerspace could help solve IV fluids crisis​

Less than an hour after Lieutenant Jon Stevens walked into a new workshop at Latchford Barracks with a rough sketch drawn on the back of an envelope, he was holding a 3D-printed prototype of his design.

This quick turnaround from idea to physical product is one of the goals of a new army initiative.

The lieutenant's invention could be a game-changer for the medical industry.

And the new workshop — dubbed the Makerspace — is giving soldiers of all ranks the opportunity to flex their creative muscles too.

Big problems, simple fixes​

Lieutenant Stevens's invention — a non-sterile intravenous fluid bag — was designed and 3D printed in the Makerspace at the army base near Wodonga, in north-east Victoria.
It's about the size of your palm, and looks almost identical to a sterile IV fluid bag — but it's going to save a lot of money, and waste.

Before Lieutenant Stevens' breakthrough, army medics-in-training were using thousands of the sterile IV fluid bags per course.

"We make them use a new one every time they get a new patient, to train them into the good habits they need as medics," he said.

"Instead of us spending lots and lots of money every year to use new bags, we can simply use about 6 cents worth of putty and some plastic, and we can make a new bag every time, as many as we want, as much as we want."

The invention could also be used to help solve a shortage of IV fluids in the medical system, by allowing trainee nurses to practise without using the valuable sterile solution.

'Creative outlet' for soldiers producing game-changing inventions

A soldier's brainwave has the potential to help provide a cheap, easy-to-replicate solution to the global IV fluids crisis, and other army personnel are being encouraged to get creative too.
