We're all used to relying on familiar methods to track locations-GPS, maps, and location services on our phones. These tools have become part and parcel of our lives, helping us find our way from one place to another.

But what if there was another, more surprising way to track our movements? Thanks to AI, scientists have found a new approach.

This fresh method is paving the way for a whole new understanding of how we can track where we've been. Let's explore how it works.

The New Way to Trace Your Journey

Researchers at Lund University in Sweden have introduced a fascinating AI tool that can track a person's recent locations by analysing the unique microorganisms they pick up along their journey. Published in Genome Biology and Evolution, this study reveals how bacteria, fungi, and algae acting as microscopic "fingerprints"cling to us and carry information about the places we've been, whether it's a beach, train station, or park.

Unlike GPS, which depends on satellites, this new system, called the Microbiome Geographic Population Structure (mGPS), links microbial communities to specific regions. Because microorganisms vary by location, scientists can trace someone's travel history through their "microbiome trail." This breakthrough demonstrates a remarkable new way to study and understand human movement using the unseen communities around us.

The Microbiome Geographic Population Structure

To create this groundbreaking tool, Lund University researchers trained their AI model with a huge dataset of microbiome samples from a range of environments worldwide.

They collected microbial genomes from urban areas and subways across 53 cities, analysed 237 soil samples from 18 different countries, and studied 131 marine microbiomes from nine bodies of water.
By studying these samples, the AI learned to identify unique "microbial fingerprints" and associate them with specific geographical locations.

Eran Elhaik, a co-author of the study, highlighted that, unlike human DNA, our microbiome changes constantly as we move through different places. "By tracing where your microorganisms have been recently, we can understand the spread of disease, identify potential sources of infection, and localise microbial resistance. This also opens up new opportunities in forensics," Elhaik said.

Precision Tracking with mGPS

Demonstrating impressive accuracy, the mGPS system has shown it can effectively trace microbiome samples back to their origins. The AI model correctly identified the city for 92% of the urban samples and even distinguished nearby subway stations in Hong Kong separated by just 564 feet.

In New York City, it could tell apart locations as close as a kiosk and a nearby handrail. However, the tool's precision dropped in London, where it only accurately categorised half of the samples, likely due to the less maintained state of London's underground stations, as noted by the researchers.

Conclusion - Unlocking New Possibilities Of AI Microbiome Tool

This AI tool has the potential to impact multiple fields, from medicine to forensics. By examining microbiome data, scientists could track how infectious diseases spread, pinpoint sources of microbial resistance, and even help solve crimes by matching microbiome clues to locations.

As the system improves with more data and refinements, its accuracy is expected to increase, unlocking further possibilities for real-world applications. This innovation offers a promising new perspective on microbial geography and environmental interactions, hinting at a future where AI-driven research can transform our understanding of microbes and the world around us.
