Jurassic Katydids Sing in Ultrasound, Pre-Bat Era

Researchers reconstructed the calls of 165‑million‑year‑old insects from fossilized wings found in Inner Mongolia, China, using lasers, computer models and AI. Most species produced low calls around 5 kHz, but Sigmaboilus peregrinus likely vocalized above 20 kHz (ultrasonic), making it the oldest known ultrasonic animal vocalization and predating bats. The findings challenge the idea that bat predation was the sole driver of ultrasonic signaling and suggest predators beyond bats and acoustic niche competition shaped early insect communication. The work combined phylogenetics, laser vibrometry, wing‑vibration simulations, and machine learning, and was published in PNAS.

Soft skin patch speeds REM sleep onset by 43 minutes

UT Austin researchers developed a soft wearable patch called NEUSLeeP that combines gentle ultrasound stimulation with real-time brain monitoring to noninvasively reach deep brain regions involved in REM sleep. In a 28-person study, users entered REM sleep 43 minutes earlier and remained in REM about 16 minutes longer. The patch also increased heart rate variability and showed brain circuit changes linked to emotion, suggesting potential for treating sleep disorders and reducing stress. The device could enable at-home sleep monitoring and research, with larger trials planned and a patent filed as UT’s commercialization office moves toward market.

Ultrasound Wearable Accelerates REM Sleep Without Drugs

UT Austin researchers developed a soft wearable patch (NEUSLeeP) that uses ultrasound and real-time brain monitoring to noninvasively target REM sleep, making users enter REM 43 minutes faster and stay about 16 minutes longer in a 28-person study, with evidence of improved heart-rate variability and changes in emotion-related brain circuits, hinting at benefits for stress and mood regulation and potential applications for PTSD, depression, and insomnia; larger trials and commercialization are planned.

Ultrasound Tongue-Reading Turns Silent Talk Into Speech

A prototype uses an under-the-chin ultrasound probe to read tongue movements and translate them into decoded speech, enabling private, sound-free communication. With about 50 hours of training data, it achieves roughly 15.6% error and can generalize across speakers with similar accents, though the current probe is bulky; future versions could resemble a wearable patch.

Low-Intensity Ultrasound Reprograms Immune Cells to Halt Joint Inflammation

Researchers at the University of Alabama in Huntsville report that continuous low‑intensity ultrasound can shift macrophages from a pro‑inflammatory M1 state to a reparative M2‑like state, lowering inflammation and promoting tissue repair after joint injury. This non‑invasive approach could help prevent post‑traumatic osteoarthritis, with findings based on a fibronectin fragment injury model and transcriptomic analysis; however, the work is laboratory‑stage and requires animal validation before clinical use.

Midjourney ventures into medical imaging with spa-style water-body scans

Midjourney, best known for AI art, announced Midjourney Medical, a spa-like venture in San Francisco that uses a water tank and 40 ultrasound modules to perform full-body scans and reconstruct MRI-like images; the project relies on Fullbody Ultrasound Computational Tomography, aims for 50,000 scanners by 2031 and up to a billion scans per month, with FDA approval planned as it expands to a spa by late 2027; Butterfly Network provided the hardware under a co-development deal, but the collaboration and regulatory, data privacy concerns remained under the radar in the initial announcement.

The Pacemaker Patch: An External Ultrasound Approach to Pacing the Heart

Researchers envision a chest-mounted patch that uses high-frequency ultrasound to pace the heart, made possible by a gene-therapy step that makes heart cells produce a sound-sensitive protein; the system would pair with a pocket-sized data/power module and has shown responses in rats, pigs, and human heart cells. While intriguing as a potential alternative to implanted pacemakers, it remains experimental, with safety, regulatory, and practicality questions to resolve before clinical use.

MIT's Wearable Ultrasound Patch Paces the Heart Without Surgery

MIT researchers have created a chest-worn hydrogel patch that noninvasively paces the heart by enabling engineered heart cells to respond to ultrasound via a gene-therapy primer—a technique called sonogenetics. In tests on rats and pig hearts, the patch restored steady rhythms during daily activity, pointing toward a potential noninvasive alternative to implanted pacemakers and, with future closed‑loop sensing, a fully automated pacing system.

Wearable Ultrasound Patch Aims for Continuous Fetal Monitoring

Scientists have developed UPatch, a wearable abdominal ultrasound patch that can continuously monitor a fetus, autonomously image the womb, measure biometric parameters, and flag issues like preeclampsia; in tests with 62 pregnancies and 52 women over 1–6 hours, it performed on par with standard ultrasound and could broaden access to prenatal imaging, though it relies on a bulky backend and may be limited by movement; the study is published in Nature Biotechnology.

Wearable ultrasound patch promises continuous fetal monitoring

Researchers have developed UPatch, a wearable ultrasound patch that can continuously image a fetus and track blood flow and heart rate, addressing the limitations of intermittent hospital scans. The device is currently a tethered, proof-of-concept and was tested against conventional ultrasound in 62 pregnant participants, with 52 pregnant women undergoing continuous monitoring. In one case of pre-eclampsia, UPatch helped reveal intrauterine growth restriction, prompting a cesarean delivery. The team envisions a wireless version for home use, with potential benefits for low-resource settings and earlier detection of complications.

Lab Ultrasound Strategy Ruptures Enveloped Viruses, Offering a New Antiviral Avenue

Lab experiments show ultrasound in the 3–20 MHz range can cause acoustic resonance to rupture the envelopes of enveloped viruses like SARS-CoV-2 and influenza A (H1N1), rendering them non-infectious in cell models while leaving host cells unharmed. It's a promising, non-invasive approach, but still early—not a treatment yet—with ongoing work to refine frequencies and test other viruses.
