Scientists at ETH Zürich created a living building material with light-powered bacteria that pull carbon dioxide out of the air and slowly turn it into stone inside the material, making it stronger over time while helping clean the air.

Swiss scientists have created a «living» building material that eats CO₂ and turns into stone It contains bacteria that, with sunlight, convert carbon dioxide into minerals — so the material hardens over time. The idea is to coat building facades with it, so houses literally «breathe» and clean the air.

This is a device I use in my office: it draws outdoor air from outside the window into the room, passes it through a filter, and then vents it indoors. The excess air pressure pushes indoor air out through the gaps around the door. This way, indoor carbon dioxide, particulate matter, and VOCs can be reduced to very low levels. Even an air purifier with activated carbon cannot achieve this effect, because air purifiers cannot lower CO2 concentration. This device is modified from an AirFanta 3Pro. I reversed the fan installation and connected two reducing adapters so that the final diameter matches that of this plastic expandable duct. Finally, I sealed the window with a sealing fabric, leaving only an opening the same size as the duct. Its only drawback is the lack of heat exchange, so it requires some additional air conditioning load. It would be unsuitable in very cold or very hot places.

$🚨UNIPHICS NEWS🚨: Light doesn’t slow down in glass — time does. And that explains every rainbow you’ve ever seen 🧨 For centuries, we’ve been taught that light slows down when it enters glass, water, or any transparent material, and that this slowing causes refraction and the splitting of colors in rainbows and prisms. The refractive index is treated as a material property, and photons are pictured as particles mysteriously changing speed inside matter. Uniphics offers a much cleaner and more fundamental picture. Light is a propagating spin-wave mode in the ξM-field. When this wave enters a material like glass, the material increases the local energy density. Because time flow is directly tied to energy density (t_flow = k / E_d), time flows more slowly inside the glass than in air. The spin-wave pattern of light therefore takes longer to advance through the region of slower time flow. This change in the rate of time progression across the boundary causes the wave to bend — exactly what we observe as refraction. Different wavelengths (colors) interact slightly differently with the energy-density environment, so they bend by different amounts, creating rainbows. Nothing actually slows down in the classical sense. The wave simply experiences a different rate of time flow inside the material. The same principle that explains gravitational lensing also explains ordinary lenses and rainbows. This turns one of the most familiar phenomena in optics into a direct consequence of variable time flow caused by energy density gradients. How might realizing that refraction and rainbows are caused by local changes in time flow rather than photons slowing down change the way we think about light, materials, or the design of new optical technologies? A Theory of Everything should be able to answer everything. Uniphics Explained Simply PDF: Chapters 1–10 free: Grokipedia #Uniphics #Refraction #Rainbows #TimeFlow #Light Grok xAI$

🚨 SCIENTISTS JUST CREATED A “LIVING” METAMATERIAL THAT CAN SELF-HEAL AND CHANGE ITS PROPERTIES IN REAL TIME. Researchers have developed a metamaterial made from living cells that can adapt its structure, heal itself when damaged, and even change its physical properties on demand. This is the first true bio-hybrid material with dynamic, life-like behavior. Why this matters: • Traditional metamaterials are static once made, they don’t change • This new material can respond to its environment and repair itself • It opens the door to self-healing buildings, adaptive medical implants, and living machines • It blurs the line between biology and engineering The deeper implication is enormous: We are entering the age of living materials objects that are not just built, but grown and evolved. The future of technology may not be made of metal and plastic… but of living, breathing, self-repairing matter. What would you build first with a material that can heal itself and adapt? Follow for more frontier physics and future technology.

🇨🇳 China's answer to a brutal heat wave: send out the water trucks. On the hottest days, sprinkler trucks hose down the roads so the water evaporates fast, pulling heat off the asphalt and cooling the air around it. It keeps the pavement from softening and takes the edge off the street-level swelter. They pull double duty too, knocking dust out of the air while they're at it. Writer: Julie

Bernoulli's Principle states that "fast moving fluid creates low pressure". The guy created low pressure outside with the water and air moves from high pressure to low pressure so it quickly sucked out the air from the room which creates deficiency of oxygen in the room and fire went out.

Ok this is actually wild. Scientists made electronics out of a soft material that mimics human tissue… so it can exist inside your body while your cells grow around it. This isn’t wearable tech. This is inside you tech. 😳 Tell me what you think. 👇

🚨 SCIENTISTS HAVE FOUND COMPLEX ORGANIC MOLECULES INSIDE MATERIAL RETURNED FROM ASTEROID RYUGU. Researchers analyzing samples from Japan’s Hayabusa2 mission have identified unusually large carbon-rich compounds in the asteroid. These molecules are more complex than many previously found in meteorites and may preserve chemical clues from the early Solar System long before life existed on Earth. While this is not evidence of alien life, it shows that some of the building blocks associated with life’s chemistry were already forming in space billions of years ago. Why this matters: • It strengthens the idea that asteroids and comets could have delivered organic material to early Earth • It gives scientists a rare look at pristine chemistry from the birth of the Solar System • It helps us understand how complex molecules can form in space without biology • It has implications for the search for life on other planets and moons The deeper question: Did the ingredients for life originate on Earth… or were they seeded across the Solar System by asteroids like Ryugu? We’re now getting closer to answering that question with actual material collected from space rather than just meteorites that survived atmospheric entry. Follow for more frontier space science and discoveries about the origins of life’s chemistry.

There aren’t enough expletives to describe this. Looks like this aircraft run out of air and decided to do a wing over to prevent a crash into the mountain. No idea of the circumstances but it appears that they, whoever they are, got away with it. 🍀

Micro concrete is a great option for bathrooms and kitchens, as it provides a hygienic and stain-free surface. What is more, the material is anti-slip and mould-free – making it a fantastic choice for floor surfaces inside and out

Since the start of the conflict with Iran, Israeli Air Force fighter jets have dropped over 2,000 bombs in hundreds of strikes against Iranian regime targets and military sites, according to the IDF. The number is around half of what the IAF used over the entire course of the 12-day war in June 2025 -- but in just 36 hours. During those 36 hours, IAF fighter jets have carried out over 700 sorties, the military says. The military says that it achieved aerial superiority within 24 hours of the start of the operation, after taking out numerous Iranian air defense systems in western Iran. IAF fighter jets are now using "stand-in" weapons over the capital Tehran, meaning bombs dropped directly over their targets, rather than ranged missiles. The military says it seeks to maintain air supremacy as it carries out strikes on regime targets in the Iranian capital. "In recent hours, air force aircraft have been operating with air superiority over the skies of Tehran, striking and destroying numerous targets," the IDF says in a statement. The IDF says that the targets included ballistic missile launchers, air defense systems, and headquarters. At the same time, IAF fighter jets, helicopters, and air defense systems have shot down more than 50 drones launched from Iran at Israel, the military adds.
