Sound-Driven Reboot: A Noninvasive Brain Fix for Addiction

Erin McNulty, a long-time meth addict, becomes part of a WVU trial testing noninvasive focused ultrasound to modulate the brain’s reward center. After initial sham treatment and then real ultrasound targeting the nucleus accumbens, her cravings dropped and she maintained sobriety for months; early trial data from the first participants show large reductions in cravings and fewer positive drug tests. The approach remains experimental, with safety questions, dose variability, and the need for behavioral support, but it’s drawing interest as a potential non-surgical option to treat addiction.

No Pricks, Big Hopes: The Quest for Noninvasive Glucose in Wearables

Researchers continue to chase truly noninvasive glucose monitoring for wearables, a notoriously difficult problem because glucose signals are small and easily swamped by other biological signals. The effort has shifted from tear-based sensors (which proved unreliable) to methods that detect glucose through the skin, with Raman spectroscopy showing promise but requiring highly sensitive, bulky optics. MIT researchers have developed a working shoebox-sized prototype that reads skin glucose signals and aims to miniaturize it for wearables, with a startup partner planning market release around 2029–2030 after FDA clearance. The path to a consumer device like an Apple Watch remains long due to the need for medical-grade accuracy and substantial miniaturization, but progress continues on narrowing the signal-to-noise gap and shrinking the technology for everyday use.

Scent Reveals How Egyptian Embalming Evolved Across Millennia

Researchers noninvasively analyze volatile organic compounds in the air around 19 mummies (35 samples) to identify embalming ingredients and how recipes changed from fats/oils in early periods to beeswax, resins, and bitumen by the New Kingdom, using headspace SPME with GC-MS; the study links scent, trade, and ritual beliefs while offering a rapid screening method that preserves the artefacts.

Compact Hypoglossal Nerve Stimulator Delivers 93% Airway Opening in Sleep Apnea Trial

Researchers at Flinders University tested a smaller electrode for hypoglossal nerve stimulation to treat obstructive sleep apnea. In a short trial, 13 of 14 participants had their airway opened during stimulation (93% success), with a 90-minute ultrasound-guided procedure that is less invasive than current implants. If validated in larger, real-world studies, this approach could provide a quicker, more customizable alternative to CPAP and existing HNS. Further development and testing are planned.

Noninvasive Genomic Profiling Identifies Unique Hodgkin Lymphoma Subtypes

Researchers have identified distinct subtypes of Hodgkin lymphoma using noninvasive genomic profiling, which could help guide personalized treatment strategies for patients. The study analyzed tumor samples from over 1,000 patients and identified five distinct subtypes based on their genetic characteristics. These subtypes were associated with different clinical outcomes and response to treatment. The findings highlight the potential of genomic profiling in improving the precision of cancer care and tailoring therapies to individual patients.

Advancements in Ultrasound Technology Revolutionize Brain Research and Medical Exams

Researchers at Rice University have successfully tested a noninvasive, ultrasound-based technique for gene delivery to multiple regions of the brain in rodents. The technique, known as focused ultrasound blood-brain barrier opening (FUS-BBBO), allows for the safe and efficient delivery of gene therapy throughout the brain, potentially overcoming the challenges of treating genetic disorders that affect large brain regions. The study found that the efficiency of gene delivery improved within each targeted site when more sites were opened, suggesting the potential for enhanced treatment outcomes.

Advancements in A.I. allow for passive mind-reading through text conversion.

Scientists at the University of Texas at Austin have developed a noninvasive AI system called a semantic decoder that can translate a person's brain activity into a stream of text. The system was trained using a transformer model and requires no surgical implants. It could benefit patients who have lost their ability to physically communicate. The decoder can generate a stream of text when the participant is listening to or imagines telling a new story. The researchers have filed a PCT patent application for the technology.
