“A wise man, therefore, proportions his belief to the evidence.”
David Hume, 1748
April 13, 2026 — People often invert scientific judgment: they dismiss real but counter-intuitive science — like quantum physics — while entertaining speculative or fictional ideas that merely borrow the language of science. The contrast is evident in how cases like Havana Syndrome and, more recently, the alleged CIA “Ghost Murmur” top-secret project have been discussed in the media. Follow us on Twitter: @Intel_Today

We have come a long way since I first coined the term “Havana Syndrome” nearly a decade ago, suggesting that the reported symptoms could be explained by exposure to microwaves.
A recent article from Nobel Prize Outreach quotes Professor James C. Lin — an expert on the microwave auditory effect — as describing this mechanism as the most likely explanation.
Whether such attacks occurred or not, the underlying science is real and well established.
Back to the present — According to media reports, a futuristic tool called “Ghost Murmur” was allegedly used for the first time to locate and rescue an American airman shot down in southern Iran.
The system is described as using long-range quantum magnetometry to detect the electromagnetic signal of a human heartbeat, combined with artificial intelligence to extract it from background noise.
This story is scientifically untenable. While quantum magnetometers are real, the magnetic field produced by the heart is extraordinarily weak and only measurable in controlled, shielded environments with sensors placed very close to the body.
From basic electromagnetism, a cardiac magnetic field behaves like that of a small magnetic dipole. This means its strength decreases extremely rapidly with distance, falling off with the cube of the distance.
In practical terms, even modest increases in range cause the signal to collapse far below the background noise floor, making individual heartbeat detection in open, uncontrolled environments effectively impossible under known physical constraints.
