Incredible new study at Washington State University found Egyptian Blue emits near‑infrared light 🤯 This is a fragment of ancient Egyptian Blue paint. When researchers hit it with visible light (green, around 530–550 nm), the pigment absorbed it and re‑emitted near‑infrared light at 910–940 nm. Our eyes can’t see...

The Egyptian Blue - more than just a colour... Around 200 years ago, chemist and inventor Sir Humphry Davy went to the ruins of Titus’ baths in Rome. There, ‘amongst some rubbish, [he] found several large lumps of a deep blue frit’. Soon after, Davy found the same material on a pot in Pompeii. He realised that he had rediscovered the material ‘of which the manufacture is said to have been anciently established at Alexandria’, the first synthetic pigment, Egyptian blue. The tale of Egyptian blue’s discovery, ‘disappearance’ and rediscovery is a fascinating one, and illustrates beautifully how art can act as a facilitator for the advancement of chemistry. For the ancient Egyptians, blue was a very important colour. It was associated with the sky and the river Nile, and thus came to represent the universe, creation and fertility. However, in ancient times, only the earth colours (colours provided by the surface soil) were used as pigments – blue could not be easily obtained by Egyptian artists. Indeed, the only natural source of blue was the rare and expensive mineral lapis lazuli, which was mined in what is now Afghanistan. However, at around 2600 BC, Egyptian blue enters the historical record, and use of the pigment gradually spread across the ancient world as far as Mesopotamia and the Roman empire before being apparently lost in the dark ages. Sadly no Egyptian recipe for the pigment remains, but Vitruvius, a Roman writer in the 1st century BC, stated that sand, copper (from a mineral such as azurite or malachite) and natron (a naturally occurring mixture of sodium compounds, including sodium carbonate) were the ingredients. Modern experiments show that Egyptian blue (chemical formula: CaCuSi4O10) can be obtained by heating these chemicals to 800–900°C with the addition of lime, a calcium-containing material, which must have been present in the ancient method, probably as an impurity in the sand. Whether its discovery came about by design or chance, the synthesis of Egyptian blue was a seriously impressive accomplishment. Achieving necessary temperature control for successful reaction would have been a major challenge, as indeed would the correct addition of oxygen. Another testament to the skill of Egyptian chemists is consistency of the pigment throughout history. Composition in artworks such as the mastaba (tombs) of Mereruka, from the Old Kingdom (2600–2100 BC), is almost exactly the same as that found in a mummy coffin dating from the Greco-Roman period (330 BC–AD 400), and there are other examples dated between these two that show similar compositions. In an exciting development for chemists and artists, it was reported in 2009 that Egyptian blue shows exceptional luminescence in the near-infrared region.3 This means that the pigment can be easily detected in a completely non-destructive fashion simply by illuminating ancient works of art with near-infrared radiation. The luminescence is so strong that the presence of minute amounts of Egyptian blue can be detected even when no blue colour is visible to the naked eye. The British Museum was able to use this technique to provide the first proof that the Elgin Marbles had once been painted, finding the pigment on several sculptures from the Parthenon. 🎥© Hidden Epochs #archaeohistories

🚨 SCIENTISTS JUST BUILT AN ARTIFICIAL RETINA THAT RESTORES VISION AND ADDS INFRARED SIGHT. Researchers at Yonsei University in South Korea have developed a flexible, three-layer implant that bypasses dead photoreceptors and directly stimulates healthy retinal ganglion cells. The device not only helps restore vision in cases of retinal degeneration (like retinitis pigmentosa) but also gives the eye the ability to detect near-infrared light that humans normally cannot see. The key innovation is a soft 3D array of liquid metal micropillars (gallium-indium alloy) that gently conform to the curved retina without causing damage or inflammation a major improvement over rigid electrodes used in earlier implants. Why this matters: • Retinal diseases destroy light-sensing cells, but the neurons deeper in the eye often remain healthy and capable of sending signals to the brain • The implant uses an ultrathin filter + phototransistor array to convert near-infrared light into electrical signals the ganglion cells can understand • In mouse tests, blind animals regained visual responses, while healthy mice gained infrared sensitivity on top of their normal vision • The liquid metal electrodes are soft and biocompatible, dramatically reducing the risk of scarring or tissue damage The deeper implication: This isn’t just about restoring lost vision it’s about augmenting human sight. If it reaches human trials and proves safe long-term, people with partial vision loss could keep their remaining natural sight while gaining an entirely new sensory channel (infrared). The biggest open question is how the human brain would interpret this new stream of information whether it would feel like a new color, an overlay, or something else entirely. We’re moving from “fixing blindness” to “expanding what it means to see.” How do you think gaining the ability to see infrared light would change daily life or human perception?

When a nuclear reactor is switched on for the first time, an intense, almost hypnotic blue glow appears in the water surrounding the reactor core. This light is neither fire nor heat; it is Cherenkov radiation, a physical phenomenon that occurs when charged particles, such as high-energy electrons produced during nuclear fission, travel through a transparent medium faster than light can propagate within that same medium. While nothing can exceed the speed of light in a vacuum, light travels more slowly in materials like water. When a charged particle surpasses this reduced speed, it emits a coherent shock-like electromagnetic wave, often described as an optical analogue of a sonic boom. This radiation produces the distinctive blue glow. The colour arises because Cherenkov radiation is strongest at shorter wavelengths, which are dominated by blue and ultraviolet light. The phenomenon was first observed experimentally in 1934 and later explained theoretically, work that led to the Nobel Prize in Physics in 1958. Its explanation confirmed how relativity and electromagnetism operate in material media. Today, this deep blue light is both a warning and a scientific tool. It signals the presence of intense ionising radiation, while also being exploited in particle detectors, nuclear reactors, and neutrino observatories. It provides a rare, visible manifestation of subatomic processes that are otherwise hidden from direct human perception. #GottaLovePhysics #Physics

You Can Heal Yourself With Nature Movement - By moving our body we give strength to our muscles, promote blood flow and lymphatic flow enhancing the delivery of nutrients and the removal of waste products. We also create a piezoelectric effect that energises the system. Breathing - The delivery of air into the body through intentional conscious breathing is one of the most powerful modalities for nervous system renewal, mental peace and the delivery of oxygen to the body and the removal of carbonic acid buildup from the system Sunshine - It’s my belief that the more sunlight we absorb without sunscreen, the healthier we will become. A tan looks good because it is healthy and every part of your body thrives when sunlight touches it delivering blood flow as well as a high frequency and energy Grounding - Existing in connection with the earth’s electrical fields resets everything about our energy, reduces inflammation and promotes the movement of proper channels such as detox - it’s a fantastic practice to be connected to nature. Green light - When sunlight moves through trees and leaves we receive Green light by which is very healing and high in near infrared light, in fact it is one of the most healing modalities to absorb in your skin particularly if you have any abrasions or wounds - even more powerful than red light . Fresh air - The first nutrient, having fresh air that is rich in oxygen is absolutely imperative to health and you should always have all of your windows open in the house if possible when not outside. Positive thinking - Whatever you think, shall become and having and cultivating a positive mindset that intentionally brings you positive energy is one of the cornerstones to great health. You can think yourself into sickness and you can think yourself into health so choose to view the world in a positive light and so it’ll be for you.
