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)

🚨 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?

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.

🇺🇸🇷🇺 THAAD vs S-400: TWO VERY DIFFERENT AIR DEFENSE PHILOSOPHIES THAAD and Russia’s S-400 are often compared as if they perform the same mission. Technically, that is misleading. THAAD is primarily a dedicated ballistic missile defense system. Its interceptor uses hit to kill technology, meaning it destroys the incoming warhead through direct kinetic impact rather than relying on a conventional explosive warhead. It is designed to engage ballistic missiles during their terminal phase, including both inside and just outside the atmosphere. Its AN/TPY-2 X band radar provides high resolution tracking and target discrimination, allowing the system to distinguish the actual reentry vehicle from other objects and continuously update the interceptor with precise tracking data. S-400 follows a different philosophy. It is a multi role long range air defense architecture designed to engage aircraft, cruise missiles and selected ballistic missile threats using different interceptor missiles. Its strength is not simply the advertised maximum range, but the combination of multiple radars, command and control, mobile launchers and different missile types. This creates a major technical distinction: THAAD = specialized upper tier ballistic missile defense S-400 = broader long range integrated air defense THAAD's interceptor is optimized for the difficult terminal ballistic missile problem, where the target may be travelling at extremely high velocity and descending rapidly toward the defended area. S-400's architecture is optimized for flexibility, allowing commanders to select different interceptors depending on target type, altitude and engagement geometry. The real question therefore isn't "Which system has the longer range?" It is: Which system is better suited to the threat? Against ballistic missile warheads, THAAD's architecture is specifically optimized for the mission. Against a mixed package of aircraft, cruise missiles and other aerial targets, S-400 offers a much broader engagement envelope. And in a modern war, neither system is supposed to operate alone. The real advantage comes from layered defense, where long range sensors, command networks, THAAD, Patriot or other systems work together. Range is only one number. Radar architecture, target discrimination, interceptor kinematics, engagement altitude, reaction time, saturation capacity and network integration ultimately determine whether an air defense system survives a real missile raid.
