Victims of Mystery Attacks In Cuba Left With Anomalies In Brain Tissue (arstechnica.com)

An anonymous reader quotes a report from Ars Technica: American victims of mysterious attacks in Cuba have abnormalities in their brains' white matter, according to new medical testing reported by the Associated Press. But, so far, it's unclear how or if the white-matter anomalies seen in the victims relate to their symptoms. White matter is made up of dense nerve fibers that connect neurons in different areas of the brain, forming networks. It gets its name from the light-colored electrical insulation, myelin, that coats the fibers. Overall, the tissue is essential for rapidly transmitting brain signals critical for learning and cognitive function.

In August, U.S. authorities first acknowledged that American diplomats and their spouses stationed in Havana, Cuba, had been the targets of puzzling attacks for months. The attacks were carried out by unknown agents and for unknown reasons, using a completely baffling weaponry. The attacks were sometimes marked by bizarrely targeted and piercing noises or vibrations, but other times they were completely imperceptible. Victims complained of a range of symptoms, including dizziness, nausea, headaches, balance problems, ringing in the ears (tinnitus), nosebleeds, difficulty concentrating and recalling words, permanent hearing loss, and speech and vision problems. Doctors have also identified mild brain injuries, including swelling and concussion. U.S. officials now report that 24 Americans were injured in the attacks but wouldn't comment on how many showed abnormalities in their white matter.

    Extraordinary claims require extraordinary evidence. There isn't any.

    Doesn't a fair number of people with similar and rare brain abnormalities constitute exactly that? I wasn't sure myself if anything was really going on, but this fact makes it seem much more compelling that something real was going on.

    Put it the way - why do you have reason to doubt what they are all saying?

    I'm not going to propose that there is no mystery here, but when probing something this mysterious and examining people as intensely as they are likely examining these individuals, I'd want to go with a setup that tests both people who were there and people who weren't. I'd also want to hide the identities from those reading the scans.

    No human would be without anomalies if tested intensively enough.

    A specific claim like "it was a sonic weapon used by the Russians" might require extraordinary evidence.

    But if there's a bunch of people in one place, and then there is credible evidence that they've all got an unusual injury-- isn't it a bit natural to draw the inference that the unusual injury may have been caused by a factor related to that place-- whether deliberate harm, accidental consequences of espionage, or some unknown pathogen, etc.

      Only if you believe that it could trick the person into hearing the noise while in a very specific location in their room (like their bed), but then have the noise stop as soon as they moved away from their bed.

  5. Microwave auditory effect device? by RhettLivingston · · Score: 5, Insightful

    I have wondered from the first time I read about these embassy attacks if someone was playing with a device that utilizes the "microwave auditory effect" that this wired article was discussing in 2008.

    Perhaps they were attempting to project voices into their heads and had some sort of tuning issue that caused it to have a range of other effects.

    1. Re:Microwave auditory effect device? by Rei · · Score: 5, Interesting

      Wow, that article is eerily similar to what's been described.

      This one uses the so-called "microwave auditory effect": a beam of microwaves is turned into sound by the interaction with your head. Nobody else can hear it unless they are in the beam as well.

      There are health risks, he notes. But the biggest issue from the microwave weapon is not the radiation. It's the risk of brain damage from the high-intensity shockwave created by the microwave pulse.

      But if it does prove hazardous, that does not mean an end to weapons research in this area: a device that delivered a lethal shockwave inside the target's skull might make an effective death ray.

      Such a device had apparently already been built and tested by the US. The interesting thing to me is that the sound comes from a shockwave of the beam interacting with the body of whoever is in the beam; it's not a hallucinatory effect of the brain damage. That would mean that interactions with other objects (including microphones) in the path of the beam could also result in recordable sound, which would explain the recordings that are being analyzed.

  6. Crazy to bring Trump into this at all by SuperKendall · · Score: 4, Insightful

    You seriously think that in less than a year Trump has utter control over an array of army doctors such that they would outright lie to this extent? Come on man. He doesn't even have full control of the state department or pretty much any other department for that matter.

    Or what about the notion that Trump could coerce this many doctors to lie about this, and even if that WERE true why would the embassy staff all be sick? Do you claim that the entire staff of the Cuban embassy is making THAT up? I refer you again to my first point re: Trump and the state department - not to mention the actual timeframe in which they got sick was back in 2016 before the election. Was Trump masterfully convincing the entire Cuban embassy staff to claim they were sick at that point? To what end? I mean Scott Adams claims Trump is a master persuader but even so I'm not going to buy into Tump being that clever...

    Now I'm not willing to agree it was may not even have been an attack, maybe just some natural cause of the building. But to claim there is nothing going on at all is seriously out of whack even for the paranoid among us (which I count myself in that group). There is obviously something more to the story that is not understood at this point.

      I'm not so sure Trump is the most corrupt candidate in history, but if you say so. Unless you meant Hillary... in which case i'll remind you: 14+ years of republican driven investigations into the Clintons = 0 indictments.... meanwhile, less than a year of investigations into Trump and we already have 2 indictments, and 2 guilty pleas.. and that's with republicans controlling the house, senate, and the presidency, and we have a Trump tweet just a few days ago admitting to obstructing justice.

  7. Plausible explanation: microwave guns by pikine · · Score: 5, Interesting

    There is a plausible explanation for this mysterious attack. Currently, Microwave guns that are being used for riot-control have their frequencies tuned to be absorbed by the skin, but you can lower the frequency (longer wavelength) to make the microwave penetrate deeper, literally frying the victim's brain. When the microwave cooks the auditory region, the victim hears a phantom sound.

    There is no actual recording of the sound. What the AP released is just a synthesized simulation of what it might sound like to a victim under attack.

      That's not at how the AP described it.

      The Associated Press has obtained a recording of what some U.S. Embassy workers heard in Havana in a series of unnerving incidents later deemed to be deliberate attacks.

      The recordings from Havana have been sent for analysis to the U.S. Navy, which has advanced capabilities for analyzing acoustic signals, and to the intelligence services, the AP has learned.

      Yet the AP has reviewed several recordings from Havana taken under different circumstances, and all have variations of the same high-pitched sound. Individuals who have heard the noise in Havana confirm the recordings are generally consistent with what they heard.

      “That’s the sound,” one of them said.

      The recording being released by the AP has been digitally enhanced to increase volume and reduce background noise, but has not been otherwise altered.

      Anyway, I wouldn't be surprised at all if the US figures out exactly how the attack works, but don't disclose the fact. If the US says "We've confirmed it and have reproduced a weapon which causes these symptoms", then every government on Earth will attempt to do the same.

    That would be a bizarre pathogen indeed that can make you hear a sound - which can be and has been recorded - in a specific part of the room, disappearing whenever you move just slightly but reappearing when you pass back through that spot. And which only affects workers of the US embassy in Cuba, having never been recorded to infect anyone else, anywhere else, ever.

    There's no question that it's a baffling case, but pathogens don't pass muster. I waver between "another type of EM radiation, for which the sound is just an incidental side effect" and "a multispectral ultrasonic audio signal, for which what is heard (and what does the damage) is harmonics between the channels rather than the carriers". But at this point, who bloody knows.

    There was zero precedent for people being killed by bullets until the gun was invented and used to shoot people.

    In many ways, what is described strongly resembles ultrasound except that ultrasound reflects from density gradients (and thus, for example, the skull). A signal with multiple carriers however sounds like a more interesting possibility, as then you can get harmonics between the two waves at frequencies which are much better transmitted into the body. You'd also get second and third and so forth harmonics, which is exactly the sort of pattern you see in the embassy recording believed to be of the attack.

    But that's just a hypothesis.
