Researchers at the University of California San Diego’s Center for Wearable Sensors, recently unveiled a wearable for monitoring glucose, lactate and alcohol. A prototype of the compact device worn on the skin shows it can multitask in measuring blood sugar levels, detecting excessive alcohol intakes and at the same time, keep track of muscle fatigue continuously all at the same time.

Wearing the device known as “Lab on the Skin”, is reportedly not painful as it is only as small as a stack of 6 quarters. It attaches to the skin by way of a Velcro-like patch of microscopic needles. Each microneedle making up the patch is only about ⅕ of the width of a strand of human hair.

How Does UC’s “Lab on the Skin” Work?

Through the microneedles, the patch senses the biomolecules carried by the fluid surrounding the cells right next to the skin of the upper arm. Although barely penetrating the skin, the wearable is capable of collecting and sending data wirelessly to a proprietary smartphone app.

UC San Diego nanoengineering professor Joseph Wang, who is also the Director of the Wearable Sensors Center, describes the device as one that functions as a complete lab that works through the skin. Capable of continuously and simultaneously recording and measuring several biomarkers, wearers can have a way of monitoring their health condition while performing their day to day activities.

Although there are commercial health monitors already available in the wearables market, they measure only one biomarker. According to the UC San Diego researchers, those devices leave out other information that can help individuals manage their disease more effectively.

A monitor for glucose levels for diabetics is more helpful if it can also detect alcohol levels because alcohol can bring down glucose levels. Monitoring lactate levels on the other hand is also useful during workouts. While physical activities help in regulating glucose levels, monitoring muscle fatigue through lactate levels is also important.

Engineers at the Rice University’s Brown School of Engineering lab created snug-fit athletic shirts that are capable of monitoring heart rate and EKG data. Carbon nanotube threads woven into the shirt’s fabric gather heart rate data and EKG at the same standards set for chest-strap monitors, and had shown better performance at collecting live electrocardiogram (EKG) measurements during experiments.

Chemical and biomolecular engineer Matteo Pasquali explained that the athletic wear was sewn with nanotube fibers that are just as conductive as metal wires; but better. In addition to being comfortable, the athletic shirts are washable and less likely to break when the wearer is in motion.

Lead author Lauren Taylor mentioned that the shirt has to fit snugly on the wearer but without fear of breaking the nano threads since they used zigzag stitches that enable the fabric to stretch without the fibers breaking. Taylor also said that in future researches, they will be focusing on covering more surface area of the wearer’s skin by utilizing thicker patches of carbon nanotube threads.

While the fibers supply the wearer’s skin with steady electrical contact, they also act as electrodes that allow the shirt to transmit data via Bluetooth, to a nearby smartphone apps or a Holter monitor.

The Rice researchers believe that the nanotube fibers can have endless applications as they can be attached to LEDs or antennas in clothing. The clothing could also monitor other vital signs, such as force exertion, or respiratory rate, just by changing the fibers; geometry and adding the right electronics.

Pasquali believes that the carbon nanotube threads will become a staple material for wearables as it combines conductivity, biocompatibility, and softness of material. He added that even though the wearable market is still small, it could open opportunities for the development of a new generation of sustainable materials similar to the nano tube carbon threads. Materials that are also derived from hydrocarbons through direct splitting processes.

Study author Lauren Taylor added that other areas of potential applications include health monitors, ballistic protection in military wear, and human-machine interfaces for soft robotics or automobiles. She added that a demonstration performed years ago, proved that carbon nanotube fivers are better than Kevlar at dispersing energy on a per-weight basis.

Mountain bike enthusiasts hunger for higher levels of biking experience by trekking into dangerous paths that fuel greater excitement in every expedition. While constantly on the lookout for newer models of mountain bikes or MTBs that can further improve their performance, most MTB bikers today also harness applications that can help them manage the challenges of mountain biking with more ease.

The use of apps reduces some elements of danger that tend to diminish the pleasure of mountain biking. While upgrading one’s MBTs is alway a major goal, improving one’s skills in navigating allows MTB riders to optimize the precious hours they spend mountain biking.

Still, while there are numerous mountain biking apps being introduced in the market, some applications have become mainstream tools. After all. mountain bike riders have to rid their mind of certain worries when in the process of attaining new biking goals.

Basic Applications Used by Most Mountain Bikers When Exploring New Trails

Take note that the apps mentioned below are basic tools that a majority of mountain bikers find very useful when faced with the challenges of trekking and navigating through trails.

Reliable Local Weather App – Having a reliable weather app covering the locality of the trail you are currently blazing will keep you forewarned. Every adventurer knows that weather conditions tend to change from one region to the next, and knowing what to expect can be extremely helpful.

Strava -This application is an app that nearly all type of bikers have in their smartphone. Aside from being a freemium application, Strava not only tracks your cycling achievement using GPS data, it also enables sharing of travel info in social network sites.

MTB Project – Discovering new trails is an important aspect of mountain biking adventures, which the MTB Project app makes easier to accomplish. This app compiles and records routes and other helpful information provided by local bikers in the area being explored, particularly in the U.S.

Using the app requires using Google Maps as a provider of directions when exploring an unfamiliar trail for the first time. In case MTB Project does not provide much information about the location you are exploring, look for a similar application covering that particular area.

Google Maps – Every traveler whether on foot or riding a wheeled vehicle, loves Google Maps because it serves a s perfect back up for any journey. Moreover, Google has made improvements, which now includes allowing users to download maps even while offline. Mountain bikers find the Google Earth section the most helpful feature.

Bike Repair – Mountain bikers do not discount the possibility of getting into some mechanical trouble. However, why wait for the mishap to happen if you have firsthand information on what your bike needs to keep it in good shape when tackling all sorts of rough travel. The app contains more than 50 repair guides complete with photos; plus a multitude of different information about bike parts and fittings.

Another thing about this app is that it provides a history of the repairs that your bike has undergone. In a way, it also gives you a reason why it’s high time to look for a replacement before its wear and tear bogs you down.

While there’s a broad assortment of newer models available in the market, we suggest for you to choose from the top models recommended by savvy bikers by way of review sites. All things considered provides comprehensive information about the 10 best mountain bikes (MTBs) you can find.

ClearURLs, a well-known privacy browser extension was removed by Google from the Chrome store due to some violations that the creator regarded as ridiculous. Nevertheless, Kevin Röbert the developer ClearURLs modified the extension and successfully made an appeal to Google. As of now, the browser extension ClearURLs is still available at the Chrome Web Store for use in other browsers like Microsoft and Firefox.

Robert told The Register he was informed via email by the Chrome team that his work was removed from the store due to lack of an accurate description, keyword spam, and using permissions. Personally, Röbert believed that his extension was removed because it has the potential to disrupt Google’s business model, which helps advertisers in tracking elements via URLs. If Röbert’s presumption is really true, then Google will also try to remove other similar software extensions from the web store that also targets URLs with tracking elements for purposes of altering them.

What Does ClearURLs Do?

Kevin Röbert describes ClearURLs as one that removes tracking elements inside URLs to ensure there is no unwanted tracking individuals browse through the Internet. Röbert said that a lot of websites utilize tracking elements in their URL which enable them to monitor the users’ online activity.

Tracking codes aren’t really necessary for a website to properly work, audience will still vis8t the site even when the tracking elements are removed by the extension. URLs that are very long usually have such elements in them, to which Robert mentioned Amazon URLs as classic examples of long URLs for their products.

With the pandemic still ongoing, the use of drones for medical and commercial purposes has made different tasks possible to perform under safe conditions.

While drones were originally used for military purposes, different types of commercial drones or unmanned aerial vehicles are now being used by civilians and outside of military programs. However, drone flying activities are under strict supervision, where in the U.S. the Federal Aviation Authority is in charge. In additions, 44 out of 50 U.S. jurisdictions have enacted that laws that prescribe guideline and rules for restricted safe use of Unmanned Aerial Systems (UAS).

Continuous scientific advancement of drone technology saw to various modifications that enabled the commercial industry to offer drone in various sectors. Some examples of how drones are used today include : supply delivery, making three-dimensional maps, landscape surveying, searching for missing persons, weather forecasting, firefighting, inspection of pipelines, wildlife conservation, filming videos, taking photos, and for agricultural as well as academic purposes. .

Most Recent Innovations in Drone Technology

Drone manufacturers keep upgrading their unmanned aerial systems, often outshining existing versions in many ways of which the most recent are the following:

Intelligent Interface Many of today’s drones can now be controlled using smartphones and mobile applications. Manufacturers have created proprietary application that can be downloaded via the Apple Store for iOS devices or the Google Play Store for Android-supported devices.

Obstacle Avoidance Sensors – This feature is quite significant as a safety solution feature since the UAV has the capability to scan the surrounding environment; whilst creating a three-dimensional map. The drone operator then will be able to identify obstacles to dodge.

No Fly Zone– The latest editions of drones includes a feature where it marks restricted areas listed by the Federal Aviation Administration (FAA). This greatly ensures safety as the feature will warn the user if ever the drone gets near into one of “No Fly Zones”

Live Video Relaying of First Person View – The video camera attached to the drones have advanced live streaming capabilities that allows the drone to transmit radio signals to the controller. This gives a unique and at the same time exhilarating experience to the drone pilot as allows the drone to fly higher. Technically however, flying the drone past one’s visibility range, is considered unsafe and the advanced feature will likely require additional restriction.
