Scientists at the University of Hawaii at Manoa have developed a new 3D-printed wearable sweat sensor called the "sweatainer," which can analyze sweat and provide vital information about the wearer's health. Sweat can offer clues about dehydration, fatigue, blood sugar levels, and even serious conditions such as cystic fibrosis, diabetes, and heart failure.

The sweatainer is a small, wearable device similar in size to a child's sticker that collects and analyzes sweat. By incorporating various sensors, the sweatainer can analyze sweat in a mode similar to previous wearable sweat-sensing systems. The unique feature of the sweatainer is its "multi-draw" sweat collection method, which allows for the collection of multiple, separate sweat samples for analysis either directly on the device or sent to a lab.

Traditional approaches for sweat collection require trained personnel, special handling, and costly laboratory equipment. The recent emergence of wearable sweat sensors has addressed some of these challenges, but these devices still remain single-use. (Read more here)

The researchers hope that this will continue to drive innovation to create a future where personal health monitoring is more accessible, convenient, and insightful. In other words, soon we'll be able to track our own health without having to rely on trained professionals. Who needs a doctor when you have a sticker that can tell you everything you need to know? It's the ultimate do-it-yourself health monitoring system.

🤕 Virtual Reality Gets a Musical Fix for Nausea and Headaches

Research Shows Joyful and Calming Music Can Ease Cybersickness Symptoms

Are you tired of feeling nauseous and dizzy after using virtual reality devices? Well, it turns out that the solution may be as simple as listening to some joyful music. A recent study conducted by researchers from the University of Edinburgh found that listening to music can reduce cybersickness symptoms, such as headaches and nausea, that are commonly experienced after using virtual reality technology.

The study involved 39 participants who were immersed in a virtual reality environment and experienced three roller coaster rides. Two of the rides were accompanied by either joyful or calming electronic music, while the third ride was completed in silence. The order of the rides was randomized for each participant, and after each ride, the participants rated their cybersickness symptoms and underwent memory and reaction time tests.

The results showed that listening to joyful music significantly decreased the intensity of cybersickness, while both joyful and calming music reduced the intensity of nausea-related symptoms. The study also found that cybersickness can lead to temporary reductions in verbal working memory and reaction times, as well as slower reading ability and pupil size.

But don't worry, there's hope! Dr. Sarah E. MacPherson of the University of Edinburgh suggests that music can be used as an intervention to encourage the use of virtual reality in educational and clinical settings. So, the next time you're feeling queasy after using virtual reality, put on some happy tunes and let the music do the work!
