We have the first recorded reversal of the Southern Ocean Current:

Sounds like we're going to have an El Nino/La Nina winter this year.

While there is actual data that supports the main premise, a quick dive into the article referenced above revealed that the dire consequences is based on a computer model.
Casual readers looking at this subject must remember to keep in mind that environmental projections of doom and gloom have all been proven false. (See such events as Global warming, Global Cooling, etc.)
Most such computer models are accurate enough in the short term (days, not weeks and certainly not years.)and long term the venerable Farmers Almanac success rate has historically been more accurate in predicting a year in advance than many computer projections for temperature and climate predictions.
It will be very interesting to see if a civilization ending catastrophe event actually happens this time.

El Nino is caused by vulcanism in the Andes Mountains. That heats up the water in irregular cycles. Hotter water behaves differently than colder water. This has been known for decades.

Lake Sturgeon (sturgeon who live in lakes) in the northern US live over 400 years according to a new report.
A new species of feline has been identified in Bolivia, Leopardus tilcayo, the first new member of that clan in over 100 years. There are 41 living kinds of cats. The number isn't totally agreed as some scientists dispute if things like the Irimote Cat are a separate species or not. The Irimote cat (Prionailurus bengalensis iriomotensis) is a critically endangered small wildcat found exclusively on Japan's Iriomote Island. The entire species was thought to descend from a single pregnant housecat who washed up on the island decades or maybe centuries ago but some now think it descends from a single pregnant wildcat, Felis Bengalensis. The 41 include Felis domesticus which has recently been found to be 99.9% identical to Felis saharicas. There are 71 recognized breeds of housecat/showcat.

This is more technology, rather than physics or hard science, but in a news letter identifying new trends, was an observation that the Vacuum tube industry (you know, glass tubes used in 1950’s and 1960’s televisions and radios) was a valuation putting vacuum tubes as a industry currently valued at 3.3 billion U.S. denomination dollars.
Expected to grow to $5.5 billion USD by 2032.
Turns out, modern transistor's could not and did not replace all vacuum tubes.
Some applications (military, Aerospace, medical equipment ,telecommunications etc) need higher frequencies than transistors are capable of providing.
Who knew? An industry declared dead sixty years ago is still growing.
Side note: Voyager 1 is still transmitting, using vacuum tube tech rather than transisters.

It doesn't hurt that vacuum tubes are more resistant to EMPs.

Vacuum tubes are able to handle much higher power (voltage and amperage both) than transistors. I hadn't heard a claim that they also handle higher frequencies.

Douglas:
There is a company called YIC that posted an article on its web page making that claim (it was cited as a foot note in the newsletter.)
The specific claim was:
Quote:”… High-Power RF Niches: Vacuum-based specialized devices (such as TWTs and magnetrons) still excel in high-power, high-frequency applications like radar, satellite communications, and particle accelerators because a vacuum has zero recombination delay and high breakdown voltages.”
I sm not an expert on electronics, and have no idea just what “recombination delay” is .
Hope this helps.
