The concept of invisibility, once a fantasy from Harry Potter films, may soon become a reality. Chinese scientists from the University of Electronic Science and Technology have developed a groundbreaking camouflage material capable of rendering objects nearly invisible. This innovative material, detailed in Science Advances, adjusts its molecular composition to blend seamlessly with its surroundings, mimicking the adaptive camouflage of creatures like chameleons and octopuses. The process, called self-adaptive photochromism (SAP), allows the material to change color when exposed to specific wavelengths of light. Molecules in the material rearrange themselves to match the background, making the object imperceptible to the human eye. How It Works According to the research team, led ...

In a groundbreaking discovery, scientists have confirmed the existence of a long-theorized electric field around Earth, known as the "ambipolar electric field," which plays a critical role in shaping our planet's atmosphere. First hypothesized over 60 years ago, this weak but significant phenomenon has been observed for the first time, thanks to recent measurements from NASA's Endurance rocket mission. The findings, published in Nature, reveal that this electric field drives a "polar wind" that propels charged particles from Earth's upper atmosphere into space at supersonic speeds. According to NASA, the ambipolar electric field is a key factor in the continuous outflow of particles above Earth's poles, lifting them to altitudes higher than they would otherwise reach. This process, in t...
