A study from Southeast University China has shown that calculations on electromagnetic signals can be performed directly on the signal itself.
According to the authors, this can be understood as: "In an everyday analogy, it can be imagined as a #reprogrammable #electromagnetic #space computer that processes the #signals directly as #electromagneticwaves propagate."

Say good bye to cryogenic chilled propellant in your rocket!
Rocket Boffins@ NASA’s Jet Propulsion Laboratory recently fired up a magnetoplasmadynamic (MPD) thruster (aka "electric thruster") that runs on lithium metal vapor.
This prototype achieved power levels (120 kilowatts) beyond the highest-power electric thrusters on any of the agency’s current spacecraft.
Fully developed and paired with a nuclear power source, they could support payloads required for human Mars missions. https://www.jpl.nasa.gov/news/nasa-fires-up-powerful-lithium-fed-thruster-for-trips-to-mars/ #NASA #JPL #Princeton #ElectricPropulsion #Rockets #Space #Mars #Lithium #Thruster #RocketThruster #electromagnetic #magnetoplasmadynamic

"Meadowlands" sounds so peaceful and mellow - yet, it's a nasty electromagnetic blaster recently procured by the U.S. SpaceForce.
These systems are becoming a core capability for the U.S. Space Force to execute electromagnetic warfare where they can blast adversary satellites with beams of electromagnetic radiation (radio frequencies, microwaves) to disrupt their signals without physically damaging them. https://www.space.com/space-exploration/satellites/the-us-space-force-just-got-a-new-electromagnetic-weapon-to-jam-adversary-satellites #USSF #DoD #MeadowLands #ElectroMagnetic #Space #Satellites #Electromagnetic_Radiation #OrbitalWarfare #Satellite_Jamming #Electronic_Warfare #Microwaves #RadioFrequencies

🕹️Showcased at the latest AFCEA TechNet International exhibition, EDA supported the creation of a cyber defence demonstrator.
This VR technology brings together information from #cyberspace, #electromagnetic spectrum & #cognitive domain into a single interactive space.

People believe #Maxwell and #Einstein are the greatest physicists. But I think they are no match to Tesla.
#Tesla understood #electromagnetic #EM waves better than most physicists during his time. He was an electrical engineer who did not use the vocabulary of physicists. He did most of his experiments without using equations from Maxwell or Einstein because none of them actually reflects reality.
His Colorado Springs documents can be found here:

A #MassDriver* is a very long track stretching across the lunar 🌙 surface, angled skyward 🌌 at its far end, which is lined with hundreds of #electromagnetic coils. These fire in a precise sequence. The bucket 📦 never makes mechanical contact with any surface, guided entirely by the interplay of magnetic 🧲 fields, which is why these systems have a theoretical operational lifespan of up to millions of launches with negligible wear https://fastcompany.co.za/co-design/2026-02-24-how-elon-musks-moon-cannon-could-transform-space-travel

"The military has had directed energy weapons — which neutralize targets using focused energy such as microwaves or laser beams — for years, but this could be the first time it’s been used in combat by the US, an ex-US intelligence source told The Post."
After decades of torturing US citizens, the truth is no longer hidden. Snowden could have revealed this, but did not.

Civilian and #military operators alike need spacecraft that can withstand the brutal conditions of #space 🌌. That means resistance to #radiation ☢️, to heat, to #electromagnetic pulses and to targeted disruption. Forms of technology that make #satellites more resilient will also cut costs and improve #civilian services. #Berlin plans to spend 35 billion euros 💰 on military space capabilities between now and 2030. The challenge is speed ⏱️ and #regulation https://spacenews.com/what-germany-got-right-and-wrong-in-its-first-ever-space-strategy/

🛜 Project Spotlight: GOLIAT
The aims of #GOLIAT (5G expOsure, causaL effects, and rIsk perception through citizen engAgemenT) are to monitor #radiofrequency #electromagnetic fields exposure, particularly from #5G, provide insights into its potential #health effects, and understand how exposures and risks are perceived and best communicated. 📳
🏛️ Uni Vienna Team: Nina Vaupotič, Valeria Vitale, & Mathew White
⌛ Duration: 2022–2027

The risks with #SpaceRadiation ☢️ are assigned the highest priority among all risks associated with #SpaceTravel. Active shielding 🛡️ methods, which use #electromagnetic fields to deflect charged particles, can make #DeepSpace 🌌 travel safer and more feasible. Placing the passive shielding before the active shielding is more effective than placing the identical active shielding before the passive shielding of the same thickness https://www.sciencedirect.com/science/article/pii/S2214552423000391

How #airports like Heathrow and Gatwick could help #aliens spot #Earth
The study explored how hidden #electromagnetic leakage might look to extraterrestrials up to 200 light-years from Earth, if they had state-of-the-art #radio #telescopes like our own. Theoretically, it also suggests this is how far we would be able to look to spot aliens who have evolved to use a similar level of technology.

📶 ⚡ Our researchers, in collaboration with colleagues from Harvard University, have engineered a chip that can convert between electromagnetic pulses in the terahertz and optical ranges on the same device. Their integrated design could enable the development of devices for ultrafast telecommunications, ranging, spectroscopy, and computing.

Got pulled down a rabbit hole learning about Schumann resonances, which are electromagnetic wave resonances in the atmosphere because the area between the earth's surface and the ionosphere acts as a spherical waveguide. The energy input is from lightning, which is practically continuous (50 strikes/s) when viewed worldwide. The fundamental frequency involved is 7.83 Hz, with various weaker harmonics above that.
How I got pulled into the rabbit hole...
Of *course* people are selling woo / magic / New Age B.S. around this stuff. But I'm sorry to say, your little trace-printed-on-a-PCB antenna supposedly broadcasting on this frequency to boost its "natural healing properties" is not going to be an effective radiator at sub-8 Hz, even if you turn it into a spiral to make it longer. The wavelength of the 7.83 Hz fundamental is ~38,000 km, so a basic quarter-wave antenna should be >9000 km long...

I just wanted to let you all know that 30 May is my last day on the current @ARDC grant and that you can reach me at @wb2ifs and linkedin.com after that date. I'm going to decommission this profile.
It has been fun and a pleasure to collaborate with you all, and I look forward to continuing collaborations #Hamradio. #amateurradio #STEMeducation #STEAM #STEMM #scienceeduction #electromagnetic #spectrum.

Unifying general relativity and the electromagnetic force? (I presume this also includes the weak nuclear force at sufficiently high energies, but this summary doesn't say)
https://phys.org/news/2025-04-einstein-field-theory.html
I'm pretty much at the limit of my understanding of field theories and such just in this summary article, I don't think I'll even try their full journal article.
@cenobyte - Does Professor Skye or her research assistant have any comment on the matter?
