NASA's Parker Solar Probe Flew In And Out Of The Solar Corona And Found A Source Of High-Energy Particles That No Existing Model Had Predicted
(When NASA's Parker Solar Probe passed through the solar corona during perihelion encounters at the heliospheric current sheet, its instruments recorded energetic protons at energies far above what existing models of particle acceleration at that location could account for.)

“… A team… at the Southwest Research Institute… and… the University of Maryland’s Institute for Research in Electronics and Applied Physics has published an analysis of those measurements [link above]…, identifying magnetic reconnection at the heliospheric current sheet as the mechanism responsible. The proton energies detected were, in the study’s framing, approximately a thousand times greater than the available magnetic energy per particle that models of this process had predicted.
The finding matters for two reasons: it identifies a source of energetic particles close to the Sun that was not anticipated, and it raises questions about how far the existing understanding of reconnection-driven particle acceleration extends…
The Parker measurements suggest that picture needs revision. The magnetic island merging mechanism [the authors] identif[ied] can evidently produce proton populations at energies that challenge the boundary between what reconnection does and what shock acceleration does. Whether this source can explain a significant fraction of observed near-Earth energetic particle events, or whether it contributes mainly at energies and scales that remain confined close to the Sun, is a question the paper does not yet resolve…
Solar Orbiter, the European Space Agency mission operating in coordination with Parker, offers complementary measurements at somewhat greater distances. Comparing what the two spacecraft measure of the same particle populations as they propagate outward from the Sun will help establish which features originate close to the source and which are modified by the intervening solar wind. The energetic particle observations that puzzled researchers in the pre-Parker era now have a candidate mechanism. Whether that mechanism accounts for a large or small fraction of what actually reaches Earth remains the open question…”

Stop Chasing, Start Attracting: The Science of Becoming Magnetic

By the NewsPatron Psychology Desk #Magnetism #Psychology #BrainWaves #LawOfAttraction #Mindset We’ve all been there. You want something so bad—a job, a partner, a breakthrough—that you obsess over it. You chase it. You stress over it. And what happens? It seems to run away faster. 🏃💨 We recently analyzed a fascinating breakdown by an insight expert we'll call "The Metaphysician." She explained a concept…

“There are things done today in electrical science which would have been deemed unholy by the very men who discovered electricity, who would themselves not so long before have been burned as wizards”*…

Climate change continues. There is broad evidence (and consensus) that our environment, thus our ways of life, our livelihoods— indeed, our lives— are threatened. On the heels of a call from Trump to world leaders to abandon the climate fight, followed by a disappointing COP30 conference, it’s easy to be discouraged. But that, of course, is no answer.

Rather, we have to find ways to mitigate the damage that we’ve already locked in, even as we acclerate a transition to clean energy… which begins by (re-)framing and (re-)focusing the challenge. Ember, a clean energy think tank, suggests a candidate that, while it speaks to the moral obligations addressed by one of the models it means to augment/replace, has a more positive orientation…

Humanity is graduating from burning fossil commodities to harnessing manufactured technologies—from hunting scarce fossils to farming the inexhaustible sun, from consuming Earth’s resources to
merely borrowing them.

This isn’t a marginal climate substitution. It’s an energy revolution.

The magnetic centre is the electron: we are revolutionising how we generate, use, and connect
electrons. Solar and wind are conquering electricity supply. EVs, heat pumps, and AI are electrifying major new uses. Batteries and digitalisation are connecting supply and demand.

Three reinforcing shifts. One energy revolution. The electrotech revolution.

At its core, this revolution is driven by physics, economics, and geopolitics. After all, the arc of energy
history bends towards solutions that are leaner, cheaper and more secure.

Short-terms setbacks matter, but fundamentals matter more. And the fundamentals are stacked in electrotech’s favour.

Physics. Electrotech makes a mockery of setting fossils on fire and losing two-thirds of the energy to heat. Electrotech is three times as efficient.

Economics. Technologies get cheaper with scale. Commodities get more expensive the deeper you dig.

Geopolitics. Three quarters of the world is dependent on fossil imports. 92% of countries have renewables potential over 10x their current demand.

Electrotech has grown exponentially for decades. The difference today is that it’s too cheap to contain and too big to ignore. If current exponentials hold for five more years, global fossil demand will fall off its plateau.

Welcome to the Age of Electrotech…

A long and meaty presentation: “The Electrotech Revolution- the shape of things to come,” from @ember-energy.org.

One notes that the electrification that Ember pushes has other advocates, many of whom have been vocal for years; c.f., e.g., Saul Griffin. Still, another voice in the chorus is welcome.

As we plug in, we might send charged birthday greetings to Franz Aepinus; he was born on this date in 1724. A mathematician, scientist, and natural philosopher, he is best known for his research, both theoretical and experimental, into electricity and magnetism. Aepinus’ Tentamen theoriae electricitatis et magnetismi (1759; “An Attempt at a Theory of Electricity and Magnetism”) was the first work to apply mathematics to the theory of electricity and magnetism. And his experiments led to the design of the parallel-plate capacitor, a device used to store energy in an electric field.

Experiments prove the existence of "a new type of magnetism" called altermagnetism. Well that's interesting... although I read the article and as best I can tell there's no practical implications or applications at the moment..
