Researchers build flu detector that can diagnose at a breath, no doctor required

Add as a preferred source on Google

The influenza virus is a sneaky little bugger. In most cases, you have no idea you’re infected with it until you start to show symptoms — and by that point, it’s too late. Wouldn’t it be nice if there was some sort of early-detection device that could tell us who is secretly harboring a virus before it spreads around the entire office?

Good news: That is precisely what researchers at the University of Texas at Arlington have created with a prototype breathalyzer-style device capable of detecting flu in its early stages.

“What I have created — together with my research team and research collaborators working on this project — is a single exhale, portable, handheld, potentially wireless, battery-operated, inexpensive, breathalyzer that relies on gas-selective sensing elements, and which detects the presence and monitors the concentration of biomarkers in breath that signal a disease,” Perena Gouma, a professor in the university’s Materials Science and Engineering Department, told Digital Trends.

The specific biomarkers the breathalyzer looks for include traces of nitric oxide and ammonia, both of which can be measured using smart sensors.

“This particular breathalyzer detects flu virus infection,” she continued. “This is expected to be a personalized diagnostics tool available over the counter and it will allow the individuals to monitor their health, with the option of sharing the data obtained with their physician in real time.”

Gouma has previously developed other breathalyzers, for everything from asthma detection and diabetes monitoring to determining an endpoint for hemodialysis, the process of filtering waste products from the blood. The neat thing about breathalyzers, Gouma said, is that the technology involved can be easily modified to detect different diseases simply by changing the sensors.

In this example, for instance, it could be upgraded to instead test for Ebola.

“Use of the breathalyzer can make a significant different to catch an epidemic early and treat the sufferers, especially children and the elderly, in a timely manner,” Gouma explained. “It will also reduce the cost of healthcare.” Sadly nothing about providing germaphobe tech bloggers with a means to scrutinize sneezing colleagues, though.

As for when this technology may be available, Gouma said the team needs to carry out clinical trials, “but we are already exploring our options for commercializing this tool.”

A new AI model wants self-driving cars to think before they swerve
Forget guessing games, this self-driving AI actually shows its work.
Self driving car

Self-driving cars have gotten pretty good at driving. The harder problem is teaching them to drive safely in situations nobody planned for. We have heard horror stories of self-driving cars, behaving erratically in emergency situations, often times delaying first responders from reaching the scene.

A team at Seoul National University, led by professor Jun Won Choi from the Department of Electrical and Computer Engineering, thinks they have cracked part of that puzzle with a new AI model called SafeDrive. The research was recently selected as a highlight paper at CVPR 2026, a distinction that goes only to roughly 3% of all submissions.

Home testing could eventually become a lot more convenient. Researchs at the at the University of Illinois Urbana-Champaign has developed the VPodDuo, a pocket-sized fluorescence reader designed to measure sensitive molecular tests outside a conventional laboratory.

Its housing is roughly comparable in size and shape to an AirPods charging case, while Bluetooth connectivity sends results directly to a smartphone. Meaning, you might not have to wait in line anymore.

Your future AR glasses might finally stop making the real world look weird
Researchers have developed a new display technique that keeps virtual objects realistic without dimming the real world.

One of the biggest promises of augmented reality is blending digital objects seamlessly into the real world. Ironically, today's AR glasses often make the real world harder to see. Researchers at the Shibaura Institute of Technology (SIT) in Japan, led by Assistant Professor Xiaodan Hu in collaboration with Dr. Yan Zhang and Professor Xubo Yang from Shanghai Jiao Tong University in China, and Professor Kiyoshi Kiyokawa from Japan's Nara Institute of Science and Technology, have developed a new AR display technique that aims to make virtual objects look realistic without reducing visibility of the real world. The study was published in IEEE Transactions on Visualization and Computer Graphics.

The biggest AR problem isn't virtual objects; it's everything around them
