Can ultrasound make you smell things that aren’t there? Turns out, yes! We reliably triggered distinct scents like a campfire burn or a garbage truck by targeting our brains with ultrasound. To our knowledge, this has never been done before, even in animals. This may be a promising modality for writing to the brain non-invasively: 🧵 1/

Human safety testing for ultrasound has not been conducted since the late 1980s, when it was last done in China. Since then, the machines have become significantly more powerful, and 3D ultrasound and color flow Doppler deliver higher-intensity non-ionizing radiation than standard imaging. We know ultrasound affects cells in Petri dishes. We do not know what it does to developing human beings at the frequency and volume it is now being used. Few people ask this very simple question: Have four ultrasounds improved outcomes for mothers and babies? The answer is no. What has improved, though, is revenue generation for the maternal-fetal medicine profession. Women are being told that more testing is the right thing to do, without anyone stopping to ask whether it is actually making mothers or babies healthier. Getting a live baby in the bassinet is not the same thing as ensuring the long-term health of that child or that mother's future pregnancies. Algorithmic, automatic ultrasound for every pregnant woman is not evidence-based care. It is a protocol that has never been validated against outcomes and has never been proven safe. 👇

Dynamic ultrasound can reveal knee instability that static imaging may miss. 🔍🦵 During a combined maneuver (valgus stress + anterior drawer + tibial external rotation), ultrasound may show anterior translation of the medial tibial plateau followed by a sudden posterior snap of the posterior horn of the medial meniscus over the posterior tibial rim. Interestingly, this can occur without a visible meniscocapsular tear on ultrasound or MRI, suggesting a dynamic functional instability of the posteromedial meniscus. 💡 Clinical pearl This finding may represent an early stage of anteromedial rotatory instability (AMRI) and could precede the development of ramp lesions or longitudinal meniscal tears. 🧠 How I figured out a way to explore it • Left hand: performs the anterior drawer • Right hand: holds the probe on the posteromedial knee and applies valgus stress • Body: stabilizes the foot and applies the tibial external rotation Yes… it takes a few limbs. I like to call it “the octopus technique.” 🐙 Dynamic ultrasound = seeing knee biomechanics in real time. #MSKultrasound #KneeInstability #AMRI #Meniscus #SportsImaging #MusculoskeletalRadiology

Last year, we raised a $9M seed round from Pantera Capital with participation from Variant, Figment Capital, and Coinbase Ventures 🛡️. Since then, Doppler has become the default infrastructure for onchain assets, representing 91% of Uniswap v4 pools and 90% of DEX volume on Base. We've created $1.5 billion in value with over 6 million pools deployed and 40,000 tokens launched every day. We power the markets for Zora, Base App, Paragraph, fxhash, Coop Records, and more. We recently launched on Monad. BONK.fun runs on Doppler, HYPERSTITIONS launched their token through us, and we're aiming to power more TGEs as the ecosystem scales. Launching a token isn't like deploying a website. The mechanism determines whether you succeed or waste years. Doppler is the launch protocol for projects that are meant to last.

Another insurance denial. Another patient put at risk. We did everything right. My PA saw a patient with signs of a Deep Venous Thrombosis (a dangerous blood clot). We ordered an ultrasound, confirmed the diagnosis, and prescribed the medication to help prevent dangerous complications. But her insurance denied the medication. Why? They wanted “more clinicals.” Despite an in-person examination. Despite appropriate documentation. Despite the ultrasound result showing a blood clot. She was sent home from the pharmacy without the treatment she needed. If I failed to prescribe the medication, I would be held accountable for putting this patient at risk. When will we admit that insurance companies are practicing medicine? When will we hold companies and individuals accountable for delays in care? I am going to continue to share these denials with you so you can see what it is like to be a doctor in 2025. We have to fix this—for patients, for providers, for all of us. If you have a story, please share it with me. Let’s change this.

🚨They CANNOT SCAN kilometers into SOLID ROCK! That is what skeptics of the Khafre Project’s findings say, and they are correct to point out that Synthetic Aperture Radar (SAR) can't do this. They are also TOTALLY MISTAKEN, here is why: The Khafre team are not using conventional SAR imaging in the way critics assume. They are using a patented form of SAR Doppler Tomography, pioneered by Prof. Filippo Biondi. This is not simple surface imaging. It is a phase-coherent interferometric method that detects subtle Doppler frequency shifts caused by internal micro-vibrations within dense structures. Instead of trying to penetrate rock, it “listens” to tiny seismic vibrations in the stone. Biondi’s trick is to capture micro-motions. Tiny seismic or structural tremors slightly shift the radar’s frequency (Doppler effect). By analyzing these Doppler shifts across multiple SAR images, they can reconstruct a 3D tomographic image of what’s inside, like a CT-scan from space. Prof. Filippop Biondi's patent (PCT/EP2023/064345) explicitly describes processing “coherent vibrational Doppler information” in SAR to allow penetrating 3D imaging "over a depth of several kilometers". In other words, it effectively turns the radar into a spaceborne sonar, using Earth’s natural vibrations to “sound” the subsurface, something ordinary SAR can’t do. A peer-reviewed Remote Sensing paper describes using COSMO-SkyMed SAR data to map new shafts and chambers inside Khufu . This case study in a scientific journal shows the technique in action (with high-res 3D results!). Beyond pyramids, the technique has practical uses. For bridges and infrastructure, Biondi’s SAR Doppler method can extract a structure’s “vibration profile” from orbit. That profile highlights cracks or damage. In one study the team applied it to Italy’s Morandi Bridge before it collapsed, SAR-based vibration maps showed unusual energy spikes right at the failing pylon. They even imaged deep tunnels. The HarmonicSAR site reports they “detected for the first time the Gran-Sasso Physics Laboratory at 1.4 km below the Earth using SAR”. In other words, their tomography saw a known underground lab 1400 m under Italy! They’ve also done scans of mountain tunnels (San Gottardo). Biondi was co-author on a 2016 Scientific Reports paper tracking Iraq’s Mosul Dam instability via SAR. That study used spaceborne radar to measure tiny ground motions around the dam over time. It shows that SAR micro-motion techniques can monitor slow structural shifts on a large engineering project. In short, SAR Doppler Tomography isn’t ordinary radar, it’s like using satellites and the Earth’s own background hum to “see” underground. Think of it as applying a CT-scan or ultrasound-like method from orbit. It’s unconventional, but it’s patent-backed and has some peer-reviewed results. RECIEPTS: Synthetic Aperture Radar Doppler Tomography Reveals Details of Undiscovered High-Resolution Internal Structure of the Great Pyramid of Giza Filippo Biondi's SAR/Doppler Patent Perspectives on the Structural Health Monitoring of Bridges by Synthetic Aperture Radar HarmonicSAR (Filippos Website) Mosul Dam SAR/Doppler Project

🚨 ONE OF THE BIGGEST MISTAKES PEOPLE MAKE WITH IVERMECTIN AND MEBENDAZOLE? Starting too aggressively. In this discussion, Dr. Paul Marik explains that when using antiparasitics as part of a parasite cleanse protocol, he prefers starting with very low doses and gradually increasing them over time. Why? Because if you're going to do a protocol, it's better to see how your body responds before jumping straight to higher doses. That's the opposite of what many people online do. They want the strongest protocol on day one. Experienced clinicians often think differently: - Start low. - Assess tolerance. - Adjust gradually. It's a simple idea, but it's one that gets overlooked in a lot of parasite cleanse discussions. Visit PharmacyinUSA to access High-quality Ivermectin, Fenbendazole and Mebendazole globally 🚚

MIT engineers built an AI wristband that controls robots by reading your hand muscles. It works by using an ultrasound to capture images of the muscles and tendons in your wrist. An AI algorithm then translates those images into the exact position of all 5 fingers, tracking 22 different ways your hand can bend, twist, and extend. In demos, wearers directed a robotic hand to play piano just by moving their own fingers. To put the complexity in perspective, it takes: > 34 muscles > 27 joints > 100+ tendons ...Just to scroll your phone This device captures it all from a band the size of a smartwatch. They tested across 8 volunteers with different hand sizes, tracking everything from sign language letters to holding scissors. The team is now collecting data from hundreds more users to train robots in surgical procedures. Something like this could one day become the universal remote for robots and virtual worlds, and we're way closer than most people expect.

Abdominal wall pain: differential diagnosis A 28-year-old soccer player presented with right periumbilical pain of 2 months' duration. An MRI was performed, which showed no abnormalities in the abdominal wall. He was diagnosed with anterior cutaneous nerve entrapment syndrome (ACNES), and perineural injection was performed, with no improvement in symptoms. He came to the clinic for a second opinion, presenting with tenderness on palpation of the middle third of the rectus abdominis muscle, which increased with trunk resistance flexion. The pain decreased after this test was performed after muscle inhibition. An ultrasound assessment was completed, revealing no abnormalities in the discomfort, but evidence of increased thickness and decreased echogenicity of the tendon at its origin in the pubic ramus, associated with significant pain on sonopalpation, related to tendinosis. An evaluation was completed with a thoracic spine examination, revealing significant pain at the level of the spinous process of T8 (the rectus abdominis muscle is innervated by the T7-T12 thoracoabdominal nerves). It was decided to treat the patient with ultrasound-guided injections around the rectus abdominis tendon with 1 cc of triamcinolone and 1 cc of 2% lidocaine, and periradicular injections of the right T8 muscle with 2 cc of betamethasone and 1 cc of 2% lidocaine. The symptoms resolved immediately, and the patient did not reappear during the following two months of follow-up.

We are witnessing an extraordinary constitutional anomaly unfold before our eyes. The Nari Shakti Vandan Adhiniyam passed in September 2023 has come into force with being published in the Gazette only at 9.55pm last night. It is shocking that the Government brought amendments to a Constitutional provision that was not even published in the Gazette! This shows the Government’s unprepared and lackadaisical approach to serious lawmaking. This is also yet another evidence that the treasury benches look at Parliament as no more than a rubber stamp, not bothered about the procedures and protocol necessary for a fair legislative process.

A Smell Simulator That Uses Ultrasonic Waves Through Your Skull To Trick Your Brain Into Thinking Of A Smell That Is Not There. Instead of targeting your nose at all, the device directly targets the olfactory bulb in your brain with "focused ultrasound through the skull". The researchers say that as far as they're aware, no one has ever done this before, even in animals. “We found our ‘sweet spot’ to be low-frequency ultrasound focused right below the forehead and angled downward toward the bulbs. Specifically: • 300 kHz frequency (low enough to penetrate the skull well) • Focal depth of about 39 mm (where the ultrasound energy converged beneath the forehead) • 50–55° steering angles (to point the focus down toward the bulbs) • 5-cycle pulses at a 1200 Hz repetition rate (short, rapidly repeating bursts We distinguish between a smell and a sensation here because, subjectively, they feel different. The smells are strong and localized to the noise, almost like you could sniff around and find the source. The sensations are more diffuse: a weak, slow-onset impression of a smell, often paired with other (likely placebo) feelings, such as a light tingling on the face. Both smells and sensations are strongest on a light in-breath, so we tested by sitting there, with a probe to the forehead, mildly sniffing. Sometimes there is a slight waft of a smell that comes on over a few breaths, and sometimes it just hits you. The first time Albert smelled the garbage, he jerked his eyes open thinking a garbage truck just drove in!" The team of four are Lev Chizhov, Albert Yan-Huang, Thomas Ribeiro, Aayush Gupta. Chizhov is a neurotech entrepreneur with a background in math and physics, Yan-Huang is a researcher at Caltech with a background in computation and neural systems, and Ribeiro and Gupta are co-researchers on the project with software engineering and AI expertise.
