🧠 Digital Noses, Smart Toilets - AI Medicine Went Wild

In partnership with

AIHealthTech Insider: Issue #77

December 1 , 2025

This week brings some of the most exciting shifts in health tech - AI-supercharged cardiac MRI, smart toilets that track hydration and gut health, anti-aging molecules hiding in blood, and even a “digital nose” that restores smell.

If you’re following the rise of ambient monitoring, AI-native diagnostics, and next-gen medical devices, this issue is packed. Let’s dive in.

🫁AI LLMs Hit 98%+ Accuracy on Smoking History in Lung Cancer Care

Stanford and Sutter Health used GPT-4 and Gemini to pull detailed smoking history from clinical notes with over 96–98% accuracy.

Why it matters

• Turns messy EHR notes into reliable pack-years and quit-dates

• Builds cleaner risk models to catch second lung cancers earlier

• Cuts manual chart review time for clinicians and registries

❤️ Philips’ New AI Suite Supercharges Cardiac MRI

Philips is introducing an AI-powered cardiac MR suite, including SmartHeart planning and SmartSpeed Precise acceleration, to enhance scan speed, clarity, and ease of use. Paired with BlueSeal helium-free MR, it minimizes breath-holds and motion artifacts, making advanced cardiac imaging more accessible.

Why it matters

• Shorter setup and scan times mean higher throughput with the same scanners and staff

• Fewer breath-holds and free-breathing options make exams easier for sick and fragile patients

• Quantitative perfusion and motion-corrected imaging enable earlier, more precise heart-disease detection

😄Do You Know? Brains Learn Faster by Snapping Together “Cognitive Legos”

Princeton scientists discovered that the prefrontal cortex reuses modular neural “blocks” to instantly adapt to new tasks explaining why humans generalize far better than today’s AI systems.

Why it matters

• Reveals the brain’s secret to flexibility — it assembles reusable cognitive modules to build new behaviors on demand.

• Explains why AI forgets old skills — current models lack this block-based compositional structure.

• Opens paths for better AI and treatments — insights could improve continual learning and help patients with impaired cognitive adaptability.

🛰️ The First ‘Digital Nose’ That Restores Smell Through Neural Signals

A new device pairs an electronic nose with a tiny intranasal stimulator to help people with smell loss “feel” digital odor signals through the trigeminal nerve teaching the brain to distinguish scents without the olfactory system.

Why it matters

• Offers the first true sensory-substitution pathway for anosmia

• Helps patients detect and differentiate odors despite lost smell receptors

• Paves the way for wearable, everyday smell-restoration technology

👉 Study → Prototype device restores lost smell by teaching the brain to feel odors

💩Product Spotlight: You Track Your Steps… So Why Not Your Stools?

Kohler’s Dekoda turns your toilet into a passive health scanner that monitors hydration, gut patterns, and even detects signs of blood in the bowl. Every bathroom visit becomes a data point quietly translating waste into real-time insights you can actually act on.

Why it matters

• Transforms a daily routine into continuous health surveillance

• Flags subtle gut or hydration shifts before symptoms appear

• Opens a new era of bathroom-based, sensor-driven preventive care

✨ Surprise: The Anti-Aging Molecules Hiding in Your Blood

Researchers found indole metabolites made by a rare blood bacterium that reduced oxidative stress, inflammation, and collagen breakdown in human skin cells. Two of the strongest anti-aging compounds had never been identified before, pointing to an unexpected source of future skin therapies.

Why it matters

• Reveals overlooked blood-borne metabolites with skin-rejuvenating effects

• Offers a new biological pathway beyond traditional creams or serums

• Could inspire next-gen anti-inflammatory and collagen-protective treatments
