Wearable hydration monitor could help prevent heatstroke, scientists say
A new wearable sensor could help people avoid the dangers of dehydration by alerting them when their bodies need more water. Developed by researchers at the University of Texas, the non-invasive device continuously measures hydration levels in real time and wirelessly transmits the data to a smartphone, according to an SWNS report. "Dehydration is a silent threat that affects millions of people every day," said Professor Nanshu Lu of the University of Texas at Austin, who led the study. "Our wearable sensor provides a simple, effective way to monitor hydration levels in real time, empowering individuals to take proactive steps to stay healthy and perform at their best," she added, per SWNS. The sensor uses a method called bioimpedance, which sends a small, safe electrical current through the body via strategically placed electrodes. The current's flow depends on how hydrated the tissues are — hydrated tissue allows the current to pass easily, while dehydrated tissue resists the flow, according to SWNS. "Arm bioimpedance is not only sensitive to hydration changes, but also aligns closely with whole-body hydration measurements," said study co-author Dr. Matija Jankovic, a post-doctoral researcher in Professor Lu's lab. "Dehydration is a silent threat that affects millions of people every day." "This means the sensor can be a reliable surrogate for tracking hydration levels, even during everyday activities like walking, working or exercising," Jankovic added. To validate the device, the research team conducted multiple experiments, including a diuretic-induced dehydration study and a 24-hour real-life trial. Participants were given medication to promote fluid loss. Their hydration levels were monitored via the wearable and compared to urine samples. The device showed a strong correlation between changes in arm bioimpedance and total body water loss, SWNS reported. The findings were published in the Proceedings of the National Academy of Sciences. The new sensor could offer an accessible and wearable alternative to traditional hydration tracking methods, such as urine or blood analysis, which are invasive, time-consuming and impractical, the researchers noted. Hydration is known to be essential for regulating body temperature, maintaining organ function and supporting many other vital processes. Even mild dehydration can impair concentration and performance, while severe dehydration may lead to serious health problems like heatstroke, kidney stones and cardiovascular issues, according to experts. Beyond everyday use, the researchers believe the technology could benefit patients with chronic dehydration, kidney disease or heart conditions. Athletes, too, could use the wearable to stay safe and perform optimally, especially in hot weather. While the current model tracks relative hydration changes, Professor Lu said the team aims to develop reference data for absolute hydration levels. They are also exploring more advanced wearable formats, like breathable electronic tattoos or sweat-absorbing patches, to enhance comfort during long-term use.

Panasonic S1II studio scene: how does the speedy Lumix perform?
When you use DPReview links to buy products, the site may earn a commission. With the release of the S1II, Panasonic became the second company to market a camera with a "Partially Stacked" sensor, which uses more sophisticated readout circuits to get data off the sensor faster than possible with existing BSI designs. (Though not nearly as fast as fully Stacked designs allow.) We've had the chance to put it in front of our studio test scene to see how it performs in terms of image quality and dynamic range. Our test scene is designed to simulate a variety of textures, colors, and detail types you'll encounter in the real world. It also has two illumination modes, full even light and low directional light, to see the effect of different lighting conditions. Image Comparison This widget is not optimized for RSS feed readers. Click here to open it in a new browser window / tab. The S1II performs well at shooting our test scene, providing great image quality. Looking at base ISO Raws, the S1II captures similar levels of detail as the other 24MP full-frame cameras on the market*, though Panasonic's JPEG engine doesn't seem to get rid of quite as much moiré artefacting as Nikon or Canon's. Speaking of that JPEG engine, we've been pleased with Panasonic's colors for a while now, and the S1II is no exception; like the rest of its competition and the company's previous cameras, its colors are solid. At mid ISOs to high ISOs the S1II's noise levels are competitive. Its JPEG engine does an admirable job of reducing noise while still retaining detail. * The S1II's price puts it in competition with much slower, but higher-resolution cameras like the Sony a7CR and Panasonic's own S1RII; if you care more about image quality than speed, that's worth noting. The S1II provides a good amount of dynamic range, giving you room to pull your shadows up without the detail being overwhelmed by noise. However, given the lack of chroma noise visible in our tests, it seems like there may be some noise reduction going on, either in ACR or in-camera. Either way, there's plenty to be squeezed out of the files, with no nasty surprises, though you will see the effects of a little extra read noise if you're shooting at base ISO to maximize dynamic range. Exposure Latitude | ISO Invariance This is still a relatively new sensor, but it seems like Panasonic is getting a lot out of it. The S1II's image quality is very similar to other 24MP full-frame cameras with much slower burst rates and less capable video specs. Speaking of, be sure to stay tuned: tomorrow we'll be taking a look at video stills from the S1II.

A Glucose Monitor for Someone Without Diabetes: Optimal or Overkill?
The latest smart wearable got under my skin. Two weeks ago, I used an applicator with an intimidating needle to lodge a tiny wire into the back of my arm. Since then, the sensor has sent my blood-sugar levels to my phone every 15 minutes.
