A metalens for virtual and augmented reality

Posted by in categories: augmented reality, biotech/medical, virtual reality

Harvard’s Capasso Group has scaled up the achromatic metalens to 2mm in diameter. That may not sound like much, but it is plenty for virtual reality contact lenses. The human pupil is 7mm at widest. These guys are going to beat Mojo Lens to the finish line for smart contact lenses.

New research shows geothermal heating may have limited longevity

Posted by in categories: energy, sustainability

Though the Earth’s deeper layers have been raging at thousands of degrees for billions of years, new research involving Florida Tech has shown that tapping into that heat to produce geothermal heating for urban regions on the surface has a far, far shorter lifespan.

Immune Boosting Nasal Spray: Protects Against COVID-19 Is Also Effective Against the Common Cold

Posted by in category: biotech/medical

Research into a new drug that primes the immune system in the respiratory tract and is in development for COVID-19 shows it is also effective against rhinovirus.

Rhinovirus is the most common respiratory virus, the main cause of the common cold and is responsible for exacerbations of chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease. In a study recently published in the European Respiratory Journal, the drug, known as INNA-X, is shown to be effective in a pre-clinical infection model and in human airway cells.

Treatment with INNA-X prior to infection with rhinovirus significantly reduced viral load and inhibited harmful inflammation.

Making Of A Neuromorphic Synchronization Circuit Using Quantum Metaheuristics

Posted by in categories: computing, quantum physics, space

In this video I show how I made a self-organisating network of Kuramoto-style oscillators in a system undergoing metaheuristic-guided synchronization. There are also ways to visually demonstrate this with relatively simple hardware, such as using modified microelectronics, controlled using microcontroller circuits.

In this project, which I have dubbed “Feynman’s Quantum Fireflies” I program individual systems of oscillators which display discontinuous pas coupling which can be implemented in a network of transceiver circuits. Using the Path Integral Approach is one way to understand how the system behaves like a quantum thermal bath.
