New handheld breathalyzer flags fat burning in real time

A handheld breathalyzer developed with ETH Zurich researchers detects acetone in breath to indicate real-time ketosis and fat burning, enabling at-home weight-management monitoring. It uses a smartphone-guided exhalation and separates acetone before measurement, and its readings aligned with a gold-standard PTR-MS method in a small 12-person trial. If validated in more people, it could help users manage weight without waiting for scale changes; further testing is needed before widespread use.

Breathalyzer Firm Outage Halts Calibrations, Stranding Drivers

A cyberattack on Intoxalock disrupted its breathalyzer calibration services, leaving drivers unable to calibrate their devices and stranded; the company is offering 10‑day calibration extensions and occasional towing, with no disclosed data breach. The WIRED security roundup also covers the FBI resuming purchases of commercial location data, an Iranian-linked hack disrupting Maryland hospitals’ Stryker medical devices, an AI agent security incident at Meta, and the takedown of several botnets used in major cyberattacks.

AI-powered breathalyzer detects COVID and diseases in real-time.

Scientists from CU Boulder and NIST have developed a laser-based breathalyzer powered by AI that can detect COVID-19 in real-time with excellent accuracy. The breathalyzer could revolutionize medical diagnostics and be used to diagnose diverse conditions and disease states. The breathalyzer is non-invasive, fast, and chemical-free, and could be miniaturized for "on-the-go health monitoring." The team is now shifting its focus to a wide range of other diseases, hoping to contribute to the development of a Human Breath Atlas that maps each molecule in the human exhale and correlates them with health outcomes.
