Winter Hiking: ‘Great Smoky Mountains’ In December 2020 (Video)

The Great Smoky Mountains turned into quite the winter wonderland last week. A few inches of snow may not sound like much, but in the Southeast it’s cause to drop everything and hit the trail. Decided to try my hand at a silent (well, technically one-word) hiking video. Hope it gets you excited for winter.

The Great Smoky Mountains are a mountain range rising along the Tennessee–North Carolina border in the southeastern United States. They are a subrange of the Appalachian Mountains, and form part of the Blue Ridge Physiographic Province. 

Transportation: Why Cheap New Cars Are Disappearing (Video)

There are about 40 different car brands in the United States, but one kind of car that appears to be disappearing is the cheap car. Historically, about 20 percent of vehicle sales would have transacted below $20,000; however, they have completely dried up in the last few years. New cars are becoming more expensive, and it is unlikely those cheap cars will ever be back.

Views: Everday Things Seen In ‘8K Ultra HD’ (Video)

Life in Macro in 8K ULTRA HD / 8K TV.

8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD is the highest resolution defined in the Rec. 2020 standard. 8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. 

Health: Value Of A Healthy ‘Skin Microbiome’ (Video)

Our skin is home to billions of microorganisms, the vast majority of which are bacteria. Much like the microbiome in our gut, these microbes play a crucial part in keeping us healthy. They are part of a finely balanced ecosystem of friendly or ‘commensal’ bacteria, which protect our skin by creating an inhospitable environment for would-be invaders, bolstering the physical integrity of the skin, and training the immune system to distinguish commensal inhabitants from pathogens. A number of skin conditions are now understood to be influenced by a breakdown of this microbial ecosystem. Researchers are working out whether restoring the balance can treat these conditions. Understanding the ecology of this rich community is likely to be an important part of both dermatology and the study of the microbiome. Read more in https://www.nature.com/collections/sk…

Covid-19 Testing: First Rapid, Over-The-Counter Test Using Smartphone Is Approved By FDA

The patented detection method detects minute fluorescence signals using unique fluorescent nanoparticles and a sophisticated reader system to achieve accurate results from a clinical sample, overcoming the sensitivity limitations of typical lateral flow technology. The key elements of Ellume’s digital technology reduce the probability of false results, create new pathways to treatment, and optimize secure public health reporting. These unique features are critical to the approval, success and adoption of self-administered home testing.

Core Technology
Supercharged fluorescent immunochromatography using a quantum-dot based fluorescent particle

The Ellume COVID-19 Home Test’s core technology combines ultra-sensitive optics, electronics and proprietary software to leverage best-in-class digital immunoassay technology with next-generation multi-quantum dot fluorescence technology.

How it works
Safe, accurate and rapid self-test

The test includes a sterile Nasal Swab, a Dropper, Processing Fluid, and a Bluetooth® connected Analyzer for use with an app on the user’s smartphone. Utilizing the dedicated app, the user follows step-by-step video instructions to perform the test including a self-collected mid-turbinate nasal swab. The sample is analyzed, and results are automatically transmitted to the user’s smartphone via Bluetooth® in 15 minutes or less. Results can be shared with healthcare professionals to enable optimal therapy.

Through a secure cloud connection, Ellume’s COVID-19 Home Test can provide real-time reporting of test results to health authorities, employers, and educators, for efficient COVID-19 mapping.
