Electromagnetic water cloak eliminates drag and wake

Posted by in categories: chemistry, particle physics

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object’s wake, greatly reducing its drag while simultaneously helping it avoid detection.

The idea originated at Duke University in 2011 when researchers outlined the general concept. By matching the acceleration of the surrounding water to an ’s movement, it would theoretically be possible to greatly increase its propulsion efficiency while leaving the surrounding sea undisturbed. The theory was an extension of the group’s pioneering work in metamaterials, where a material’s structure, rather than its chemistry, creates desired properties.

Six years later, Yaroslav Urzhumov, adjunct assistant professor of electrical and computer engineering at Duke, has updated the theory by detailing a potential approach. But rather than using a complex system of very small pumps as originally speculated, Urzhumov is turning to electromagnetic fields and the dense concentration of charged particles found in saltwater.

Blood Factors Reverse Epigenetic Age

Posted by in categories: biotech/medical, genetics, life extension

Crucially, plasma treatment of the old rats reduced the epigenetic ages of blood, liver and heart by a very large and significant margin, to levels that are comparable with the young rats. According to the six epigenetic clocks, the plasma fraction treatment rejuvenated liver by 73.4%, blood by 52%, heart by 52%, and hypothalamus by 11%. The rejuvenation effects are even more pronounced if we use the final versions of our epigenetic clocks: liver 75%, blood 66%, heart 57%, hypothalamus 19%. According to the final version of the epigenetic clocks, the average rejuvenation across four tissues was 54.2%.

Researchers have demonstrated that epigenetic age can be halved in rats by using signals commonly found in the blood.

New Recipe for Single-Atom Transistors May Enable Quantum Computers With Unparalleled Memory and Processing Power

Posted by in categories: computing, particle physics, quantum physics

Linking multiple copies of these devices may lay the foundation for quantum computing.

Once unimaginable, transistors consisting only of several- atom clusters or even single atoms promise to become the building blocks of a new generation of computers with unparalleled memory and processing power. But to realize the full potential of these tiny transistors — miniature electrical on-off switches — researchers must find a way to make many copies of these notoriously difficult-to-fabricate components.

Live Nuke Still Missing In American Swamp

Posted by in categories: military, quantum physics

Quantum radar can find them.

The United States military takes extreme caution and protocol when transporting nuclear weapons, but that doesn’t mean accidents haven’t happened in the past. And a nuclear accident sounds like the worst accident of all time. Watch today’s new video where we dive into the mistakes of the military and uncover a story about a live nuke, still lost in an American swamp!
