A research team developing minimally invasive surgical technologies has demonstrated remote magnetic levitation for moving objects inside the body. Their objective is to control guidewires and catheters using magnetic fields. Because magnetic levitation is inherently unstable, it requires solving difficult control challenges, including nonlinear magnetic field behavior, real-time system...

Nearly two years ago, I reported on how I'd helped my Mum get off 8 painkillers a day because of her arthritis using a device called the "Primer Cube Magnetic Array". A PrimerCube is an open-source device designed to generate strong rotating magnetic fields based on the research of David LaPoint AND RELEASED IN 2019. These devices often use a bowl-shaped array of neodymium magnets mounted on a motor to create specific magnetic field geometries. Magnetic Plasma Control: According to La Point, these bowls create magnetic fields that control plasma, showing that formations in the plasma exist regardless of electrical input, with electricity only acting to reveal them. A friend of mine, Rachel Russell, took it upon herself to manufacture these magnetic wonders and in this video entitled "Say Goodby to Pain Forever?" I meet a bunch of amazing people from around the world to share their stories of how this device has not only eliminated pain, but also been used to: - save and extend a dogs life and cut vet bills - enhance seeds for growing food and yield - massive increases in Bovis Levels (Life Force Energy) - hugely improved SLEEP patterns and quality - improved dreams - improved thyroid function - reduced inflammation - improved skin appearance - parasite reduction - lengthened telemeres - reduced UTIs - improvements in sciatica - improvements in breast-feeding NONE OF THIS IS MEDICAL ADVICE, NOR ARE ANY OF THESE STORIES MEDICAL CLAIMS, MERELY ANECDOTES. DO YOUR OWN RESEARCH AND MAKE UP YOUR OWN MIND. TO LEARN MORE, link in comments below.

There is a new paper in Science proposing a mechanism for how homing pigeons navigate on cloudy days. (Hint: It's magnetic fields.) As with many magnetobiology papers, though, I'm skeptical of their proposed mechanism. These researchers, from Germany, found that pigeons have macrophages in their liver that accumulate lots of iron. They confirmed this with staining and other analyses. These macrophages also tend to cluster near nerve fibers in the liver (this is important for later). Then they did a really interesting experiment: - Train 34 pigeons to fly a particular 19-kilometer route. Ensure they all do this well. - Split the pigeons into two groups: treatment and control. - Inject the treatment group pigeons with liposomes loaded with clodronate. The macrophages eat these liposomes, and then clodronate kills the cells and scatters the iron. - Release the pigeons, from both groups, on an overcast day (it's thought that pigeons use magnetic fields to navigate when there is no sun). - All of the control pigeons reached their destination within 70 minutes, but the treated pigeons scattered in random directions. - (Important control experiment: The treated pigeons, released on a sunny day, flew like normal and reached their destination.) - This is taken as evidence that ??? macrophages --> iron --> navigation ??? via magnetic fields. But the mechanism is fuzzy. This experiment is super interesting, and it's clear that the treated pigeons really are unable to home to their destination using a magnetic field. But I'm not entirely convinced by the mechanism these authors propose. The main claim is that these iron-loaded macrophages "align" in a magnetic field, and that they shift according to the bird's orientation so that it can fix its direction. These macrophages (somehow) send signals to the nerve fibers in the liver, which then pass the messages to the brain, which allows the bird to navigate. The news coverage for this story suggests how this might happen: "One idea is that as the bird shifts its position relative to Earth’s magnetic field lines, the ferritin changes orientation and tugs on the web of fibers within a macrophage, possibly triggering the release of signaling molecules." (All you need to do is read the 2016 Meister paper, from the images below, to understand why such a mechanism is physically dubious.) The problem, though, is that the authors show (in their own study) that the iron in these pigeons' livers only act as a stable magnet at super low temperatures, below about 12 degrees Kelvin (or -260 degrees Celsius). At normal, physiological temperatures, the iron would be scrambled by the thermal motions of the tissue. Every measurement in the paper is taken at cryogenic temperatures, but a bird's body temperature is much higher, which means heat would likely destroy any magnetic alignment. The authors claim that MILLIONS of iron particles in the liver are all acting together to escape this effect, but they don't demonstrate the mechanism convincingly at all. If this claim is true, why not take homing pigeons (control vs. macrophage-depleted) and then rotate a magnetic field around them? You could record their neurons to see if there is some kind of signal coming from the liver.

First claimed successful replication of LK-99 Accomplished by a team at the Huazhong University of Science and Technology and posted 30 minutes ago. Why this is evidence: The LK-99 flake slightly levitates for both orientations of the magnetic field, meaning it is not simply a magnetized piece of iron or similar 'magnetic material'. A simple magnetic flake would be attracted to one polarity of the strong magnet, and repelled by the other. A diamagnet would be repelled under either orientation, since it resists and expels all fields regardless of the polarity. Caveats There is no way to verify the orientation of the strong magnet in this video, also, there are yet to be published experimental measured values of this sample. Diamagnetism is a property of superconductors but without measured and verified data, this is just suggestive of a result. Take-away If this synthesis was indeed successful, then this material is easy enough to be made by labs other than the original research team. I would watch carefully for results out of Argonne National Lab, who are reported to be working on their own synthesis of a sample. This overall corroborates two independent simulation studies that investigated the original Korean authors claim about material and crystal structure, and both studies supported the claims. Lawrence Berkeley National Lab: Shenyang National Lab: The attached video shows a small flake of their sample responding to an external magnetic field. I scroll through the video to skip to the relevant part. original video credit to: Alex Volkov

Researchers at Tokamak Energy have captured for the first time a real-time, high-speed video of plasma behaviour inside their ST40 spherical tokamak, tracking visible green and red light emissions as the fusion process occurs. This visual insight comes via a camera operating at thousands of frames per second, offering unprecedented detail of how the plasma evolves, interacts with the surrounding lithium blanket and outer regions, and ultimately radiates energy. The imaging enables scientists to observe how the ultra-hot core transitions outward into cooler zones, how magnetic confinement shapes the plasma behaviour, and how impurities or outer-region interactions influence the process. By giving a ‘star-in-a-donut’ view of fusion in action, this breakthrough adds a new diagnostic tool to the development of fusion energy, helping engineers refine the magnetic confinement, optimise plasma stability and better understand the heat and light flows at play. It was slowed down by 100x. All this was for 0.3s A tokamak is one of the most advanced devices ever created to achieve controlled nuclear fusion, the same process that powers the Sun. Its goal is simple in principle but incredibly challenging in practice: heat a gas until it becomes plasma, raise that plasma to over 100 million degrees, and confine it long enough for hydrogen nuclei to fuse and release energy. Because no material container can survive such temperatures, a tokamak uses powerful magnetic fields to hold and shape the plasma like an invisible cage. The device has a distinctive doughnut-shaped (toroidal) chamber surrounded by magnetic coils. When the machine is switched on, electric currents and external magnets work together to create helical magnetic fields that trap the plasma and keep it away from the walls. As the plasma spirals around these magnetic lines, it heats up dramatically. Additional heating comes from methods like radio-frequency waves and neutral-beam injection, pushing the plasma toward the extreme temperatures needed for fusion. Inside this tightly controlled environment, hydrogen isotopes such as deuterium and tritium can collide and fuse, releasing fast neutrons and a burst of energy. The goal of tokamak research is to reach a point where the fusion reactions produce more energy than the system consumes, a milestone known as “net energy gain.” Modern machines like ITER, JET, and Tokamak Energy’s ST40 are bringing this vision closer, using advanced diagnostics, superconducting magnets, and increasingly stable plasma control. 👉

Nonfiction Labs is building proteins that can be switched on- or off with magnetic fields. They plan to use these proteins to make cancer therapeutics, for example, that are only active near a tumor but inactive everywhere else in the body, thus reducing toxicity. The idea to do this came, interestingly, from extreme skepticism about magnetobiology as a whole and, in particular, some old-school papers that tried to explain how birds navigate by following magnetic fields. Andrew York, a company co-founder, was working at Calico when he was asked to give a talk about an area outside of his own expertise. He was handed a Scientific American piece about how birds navigate using Earth's magnetic field. He tracked down the source article, went through its citations, and became utterly convinced that the effect was not real. The classical explanation is that birds have cryptochromes, or blue-light-sensing proteins, inside of the photoreceptors in their eyes. It’s thought that these proteins act like a magnetic compass that tells the bird which direction to fly. But any time anybody studied these cryptochomes in the presence of magnetic fields, they only saw effects of less than 1% (in terms of fluorescence change) and only under very weird conditions, like at ultra-cold temperatures. The only result that seemed convincing to Andrew came from Adam Cohen’s lab, at Harvard, in which they took a synthetic molecule (called a phenanthrene–dimethylaniline) and showed that, in a weird buffer, its fluorescence would rise about 80% when exposed to a small, 0.1 T magnetic field. This obviously was not at all indicative of real biology, but at least it demonstrated that magnetically-sensitive molecules COULD exist. From there, Andrew began working with Maria Ingaramo to find proteins that might do the same, in more physiological conditions. They found that GFP (nothing special; literally the same protein everyone uses) is slightly magneto-responsive. Over several months, they engineered the GFP protein to behave more and more strongly in the presence of magnetic fields. And thus, intense skepticism —> more careful experiments —> a company that seems to be doing useful research. TL;DR: Professional haters can do great things in the world! There is always a place for skepticism. Relevant papers: Xiang, Lampson, Hayward, York, Ingaramo & Cohen, "Mechanism of Giant Magnetic Field Effect in a Red Fluorescent Protein," JACS (2025) Lee, Yang & Cohen, "Mapping nanomagnetic fields using a radical pair reaction," Nano Letters 11, 5367–5372 (2011) Ritz, Adem & Schulten, "A model for photoreceptor-based magnetoreception in birds," Biophysical Journal (2000)

For decades, biologists argued that birds migrate using magnetic fields, and that cryptochrome proteins in their eyes help them figure out where to fly. But the evidence for this has always been flimsy. In 1972, Wolfgang and Roswitha Wiltschko captured migratory European robins, put them in cages, covered the cages with a blanket, and wrapped electric coils around them. Once the birds lost their view of the sky, they still tried to move, or "hop," in the direction of their normal migration route. But when the Wiltschkos flipped the magnetic field around, the robins started hopping in random directions. They took this as evidence that, somehow, birds migrate using a magnetic sense. (Not bad!) In 2000, three theoretical biophysicists in Illinois, Ritz, Adem, and Schulten, proposed a mechanism for that magnetic sense. They argued that when blue light hits a receptor in the eye, it might create something called a "radical pair," locking two electrons into a spin state that a magnetic field could then nudge. They suggested that cryptochromes, light-sensitive proteins in the retina, might be responsible. (Speculative!) And then, in 2021, researchers apparently confirmed this! They took cryptochrome proteins from a type of migratory robin and put them in a test tube. They shone blue light at the proteins and found that this light induced them to form that transient "radical pair" state. And finally, they showed that magnetic fields could change this photochemistry where, in the presence of a magnetic field, the proteins formed fewer of these radical pairs, because the field forced a larger fraction of the excited molecules to ‘collapse’ back to their resting state. The experiment they used to measure this, though, has almost nothing to do with biology. You literally isolate the proteins, bombard them with a blue laser and, after each pulse, measure how much light the proteins absorb. For the robin cryptochrome protein, adding a magnetic field changed the absorbance *slightly.* But here’s the caveat: All of this was done in vitro, in a test tube, in a water-based buffer (rather than a cell). And, even worse, the experiment was done at 5 degrees Celsius (waaaay colder than the bird’s normal temperature) and at a low pH. And even after all this tinkering, they still *barely* saw a magnetic response! The news media didn't report many of these caveats. I randomly pulled one story from Science News and another from the University of Oxford, and neither even mentioned that the researchers ran the experiment at low temperature. The Oxford writeup actually hyped the result up more than the paper itself; that author wrote: “…the authors think the proteins involved could be significantly more sensitive in their native environment. In cells in the retina, the proteins are probably fixed and aligned, increasing their sensitivity to the direction of the magnetic field. Moreover, they are also likely to be associated with other proteins that could amplify the sensory signals." (Wow!) When Andrew York and Maria Ingaramo, two scientist working at Calico, heard about these results, they grew skeptical and decided to search for magnetically-responsive proteins — that actually work under physiological conditions — on their own. And that search, in turn, gave rise to Nonfiction Laboratories, a company that not only has created such proteins, but is now trying to commercialize them to make magnetically controlled cancer therapies that are only active near a tumor. The clip below is from my podcast.

It is done! Grok has literally built something that no one else has but anyone studying space weather would want! I will be releasing it today to the world on my website for free , and as open source for anyone to tweak, add or change things as they see fit! First we managed to resurrect the old Japanese NICT magnetosphere monitoring page, getting all the original data... then, added in the SOLAR-1 Data, and the data from the BOM Australia on the Magnetopause (shell around earth that bounces around). The magnetic field lines of the magnetoSPHERE coming from the ACE and Solar-1 data, and the bouncing shell of the magnetopause from the BOM, then we added in the Schumann resonance, to give each magnetic field line from the ACE and Solar-1 data an oscillating glow that lights up according to the current Hz of the Schumann. There is an option to turn on charged particles, which will then reflect off of , or be pulled in towards (or stay neutral) to the magnetic field of both the ACE + Solar-1 field LINES and the outer shell magnetopause from the BOM!!!! This is huge! When Bz goes green one way the particles turn RED and are reflected off of Earths magnetic field like a force field.. and when Bz goes Red, the particles turn GREEN and are accepted in to Earths fields! When neutral positive you see light blue and when neutral negative the particles are grey. Simply put, you can now look at this and know just by the particle color and their direction whether Earth was accepting or denying particle absorption!!!! Nowhere in the world has anyone put anything like this together into one model. Now we have it! All of these are toggleable on and off, so each one can be viewed on or off at any time. Also added multiple types of lighting and graphics controls , so that the user can control the amount of lighting, glow, thickness of the field lines when displayed, and the amount of the flashes per second using the Schumann hz filter, as well as the amount of brightness of each flash. Can go anywhere from 7hz up to 40+hz just like the actual Schumann resolance. You can also turn on "manual control" so that you can simulate "what would happen if" solar wind went up high or if the hz rate of the Schumann were to spike what it would look like magnetically on the spherical display of the magnetic field. Finally a record option was built in to allow for recording of movies in the program, which I have uploaded here now. Not the highest quality yet, but I figure people will use screen capture programs instead of this if they're making movies (this is fine for public use as is now imo). Also added in color controls for the background (default set to black) and for the magnetic field lines which default to Red and Blue just like the old NICT Japanese site which got shut down years ago.

🚨 SCIENTISTS JUST DISCOVERED A HIDDEN SIXTH SENSE IN HUMANS — WHAT ELSE IS HIDING INSIDE US? For centuries, humans have been told we have five senses. Sight. Hearing. Smell. Taste. Touch. But now scientists believe there may be a sixth. And it sounds like something straight out of science fiction. Researchers have reportedly found evidence that the human brain may be capable of detecting Earth's magnetic field. In other words? Humans may possess a hidden magnetic sixth sense. The same invisible force used by birds, sea turtles, sharks, and countless other animals to navigate across the planet without maps, GPS, or technology. Think about that for a second. An invisible force is passing through your body every second of every day. You can't see it. You can't hear it. You can't touch it. Yet scientists believe your brain may still be responding to it. In experiments, researchers reportedly observed changes in brain activity when magnetic fields around participants were altered. The participants weren't consciously aware anything had changed. But their brains appeared to react anyway. How much information is your brain processing that you never consciously experience? What if humans have been walking around with a hidden sixth sense this entire time? And if the brain can naturally detect magnetic fields, what else might it be capable of that science still doesn't understand? If this research is correct, this ability wasn't added to humans. It may have been there all along. Hidden in plain sight. If a hidden sixth sense can exist, what else do you think has been hiding in plain sight this entire time?

Magnetohydrodynamic (MHD) Propulsion - What Is It?" by AsteronX #ufotwitter This video, titled "Magnetohydrodynamic (MHD) Propulsion - What Is It?" by AsteronX, explains the physics, operating principles, and potential applications of magnetohydrodynamic field propulsion for aerospace and spaceflight. 1. What is MHD Propulsion? [00:15] Magnetohydrodynamics (MHD) is the study of electrically conductive fluids—such as ionized gases, plasmas, or saltwater—interacting with magnetic fields [01:04]. MHD propulsion uses electromagnetic forces to accelerate conductive fluids directly, producing thrust without moving mechanical parts like propellers, turbines, or airfoils [02:29]. 2. Physical Mechanism: The Lorentz Force [02:47] Working Principle: When an electric current passes through a conductive fluid perpendicular to an applied magnetic field, it generates a perpendicular Lorentz Force [02:47]. Pressure & Acceleration: This magnetic force directly accelerates or decelerates the fluid particles, driving fluid flow and creating thrust or pressure gradients [08:30]. 3. Atmospheric Flight Mechanics [10:03] Air Ionization: Since neutral atmospheric air is non-conductive, the aircraft must ionize incoming air into a conductive sheath, often using high-frequency (radio/microwave) pulse discharges [10:19]. Aerodynamic Integration: The accelerated ionized air can be directed over specialized airfoils—such as saucer-shaped Coandă effect structures—to generate lift dynamically across the body [11:27]. 4. Space Application Concepts [12:20] Plasma Rocket Engines: Utilizing magnetic fields and Lorentz forces to accelerate cold or superheated plasma out of a nozzle without physical grid erosion [12:31]. Quantum Vacuum Thrusters (Theoretical): The video discusses futuristic concepts using ultra-short, intense electromagnetic pulses to interact directly with quantum vacuum virtual electron-positron fluctuations [13:35]. The core concept in the presenter's design is hull-integrated disc vehicle geometry, rather than an internal thruster, linear duct, or traditional rocket nozzle. In the video, AsteronX emphasizes that for magnetohydrodynamics (MHD) to be practical in atmospheric flight, the vehicle's physical shape and propulsion system must be unified into a single structure. Key Architectural Features of the Disc/Saucer Design 360° Coandă Effect Airfoil: Instead of pushing air through an internal engine tube, the saucer geometry acts as a continuous "wing wrapped around the vehicle". Plasma or ionized air accelerated across the curved upper skin adheres to the surface via the Coandă effect, generating low pressure and continuous lift across the entire hull. Surface Boundary Layer Sheath: High-frequency pulse discharge electrodes embedded along the outer skin ionize ambient air into a conductive plasma sheath surrounding the disc. The Lorentz force directly manipulates this sheath, eliminating aerodynamic drag, shockwaves, and thermal heating during flight. Field Drive vs. Mechanical Thruster: Rather than using discrete thruster pods or jet exhausts, magnetic and electric field arrays distributed across the disc's surface manipulate the fluid directly in 360 degrees, allowing omnidirectional maneuvering without moving parts or control surfaces. (This geometry directly builds on historical field-acceleration concepts, such as Jean-Pierre Petit’s MHD aerodyne and saucer research cited in the video description).

The CIA and DARPA have been heavily involved in the research and development of mind control technology and has been a subject of interest, controversy, and secrecy since the mid-20th century. The CIA's MKULTRA program, which began in the 1950s, is perhaps the most well-known initiative in this field. This program involved extensive research into behavioral modification, including the use of drugs, hypnosis, and other methods to influence human behavior. Although primarily focused on chemical and biological agents, it laid the groundwork for later technological explorations. Project Pandora was funded by the CIA. This project in the 1960s looked into the effects of microwave beams on the brain, aiming to use such technologies for behavior and mood manipulation. This was part of early research into what would later be considered "non-lethal" weapons. Radio Frequency Energy and Microwave Technology has been studied and researched into how radio frequency energy could interact with the human brain has been documented. Projects like Pandora aimed to understand how microwaves could transmit signals to influence behavior or induce specific emotional states. Voice to Skull (V2K), also known as microwave auditory effect, involves sending sound directly into someone's head without the use of speakers. There have been claims and some research suggesting its use in psychological operations or in influencing behavior, though much of this remains speculative or classified. Heterodyning and Electromagnetic Technologies are methods involve the modulation of electromagnetic waves to interact with the brain's electrical activity. Research into these areas has been aimed at both therapeutic uses and potentially more invasive applications like mind control. Psychotronic technology is often associated with the concept of using electromagnetic fields or radiation to affect mental processes, psychotronic research has been noted in various contexts, including in Russian studies on psychotronic warfare. This term, however, sometimes borders on the speculative or pseudoscientific, with limited verifiable research in mainstream academic settings. Harvard and Yale have been involved in various psychological and neuroscience research projects, direct public evidence linking them to specific mind control research funded by CIA or DARPA is less clear. However, both universities have extensive research in neuropsychology and cognitive sciences, which could indirectly contribute to understanding how such technologies might work. Universities like Stanford, MIT, and Carnegie Mellon have engaged in research that touches on brain-computer interfaces, neurostimulation, and cognitive enhancement, areas that could theoretically overlap with mind control technologies. For instance, DARPA has funded research at these institutions for projects related to brain-computer interfaces, though the applications are often framed for medical or enhancing human performance rather than control. The military interest in these technologies often centers on weaponization, psychological operations, or enhancing soldier performance through cognitive augmentation. The use for inducing particular behaviors or emotions, especially in scenarios like false flag operations, could definitely be a possibility, but something that will never be admitted. This consists of the manipulation of individuals or groups to perform acts that benefit a hidden agenda unwillingly or unknowingly. Mind control technology, especially agencies like the CIA and DARPA, are shrouded in secrecy, with much of the research declassified or discussed in the public domain only after significant time has passed or in very general terms. While there's a clear interest in using technology to influence people's emotions and inducing behaviors for operations or nefarious purposes, it remains largely speculative or cloaked in national security classification.
