Optical cloaking and invisibility: From fiction toward a technological reality

Share This Post

Have you ever wanted to turn invisible? While it seems like we still have quite a way to go before we develop human-scale optical cloaks (devices that can “cloak” or hide objects), we’ve already made it partly a reality. Using mirrors, prisms, and lenses to manipulate light rays, scientists have been able to cloak tiny areas relatively easily, making ray-based cloaking tech one of the more feasible routes to take towards making everyday optical cloaks.

The First Solar-Powered Car Comes at a Hot Price

The Lightyear O is a revolutionary electric car powered by the sun. Developed by a Dutch startup, the four-door sedan has over 50 square feet of solar panels on its roof and hood, generating up to 43 miles of energy a day. With production now underway in Finland, the car does come with a hefty price tag at $262,000, but the company hopes to introduce a more affordable version, the Lightyear 2, by 2025.

Magneto Protein Could Help Magnets Control Brain Circuitry

This groundbreaking research by scientists at the University of Virginia has demonstrated a novel way to control the nervous systems of zebrafish and mice using magnets. This method, called magnetogenetics, involves inserting genetic constructs into neurons to make them sensitive to magnetic fields, providing a more precise and non-invasive way to control and manipulate neural circuits than traditional methods. This could one day revolutionize the treatment of brain disorders in humans. Read full article here
