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.

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

🇨🇳 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.

Carbon is in every living thing... carbon is even in the air! *exhales carbon dioxide* Carbon is what makes life go! Go! Go!… Carbon is the key to life! You’ve got, got, got to respect that!” 𝐁𝐢𝐥𝐥 𝐍𝐲𝐞 𝐢𝐧 𝟐𝟎𝟐𝟒: “We’ve created this wonderful quality of life for so many people by burning ancient carbon, ancient swamps; coal, oil, gas. We’ve just gotta stop doing that.”

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. 🍀

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.

Many people are unaware of this but Hand Dryers get disgustingly dirty due to their design and the nasty environment they’re in All you have to do is flip the blower over These units pull air from the room and to blow on your hands. Public restrooms have high humidity, aerosolized particles from toilets like fecal matter and bacteria get airborne when flushing. So does dust, lint, soap scum, skin cells, hair, and mineral deposits from water. Over time, this stuff gets trapped inside But it gets even worse, there are real studies on this. It’s a real, well-documented issue Studies have shown hand dryers can blow out bacteria, sometimes including fecal bacteria, onto clean hands because they’re circulating contaminated air I never use these anymore

There have been a lot of exaggerated claims from the IRGC in this war. At least there are those out there that are having some genuine fun with it. A user posted: The IRGC published footage of its air defenses in action, while repelling Israeli aircraft over Tehran.

🧐🇦🇪🇫🇷 The Most Advanced Mirage Ever Built Wasn't French When people think of the Mirage 2000, they think of France. But the most powerful and sophisticated version of this legendary fighter was built for the United Arab Emirates. Meet the Mirage 2000-9. Far more than a simple upgrade, the Mirage 2000-9 incorporated technologies developed for the Rafale, transforming the iconic fighter into one of the most capable 4th generation combat aircraft ever produced. Powered by the M53-P2 engine and equipped with the advanced RDY-2 multimode radar, the aircraft can simultaneously track multiple targets while conducting air to air and air to ground missions. Its arsenal is formidable: • MICA EM active radar guided air to air missiles • MICA IR infrared guided air to air missiles • Magic II short range air to air missiles • Black Shaheen long range cruise missiles • Laser guided bombs • Precision guided munitions • Conventional bombs • Air to surface missiles • Anti ship weapons • 30mm DEFA cannons The Mirage 2000-9 is also equipped with an advanced electronic warfare and self protection suite, allowing it to detect, jam, and evade enemy threats while operating deep inside contested airspace. With a combat radius stretching hundreds of kilometers and the ability to strike targets with precision, the aircraft became one of the most capable fighters in the Middle East. For years, it quietly stood as one of the region's most powerful air combat platforms, proof that even a design born in the 1970s could evolve into a world-class fighter. The Mirage 2000-9 wasn't just the final Mirage. It was the ultimate Mirage.

#ThisDayThatYear | 26 May 1999 #OpSafedSagar — the Indian Air Force’s codename for its air operations during the KargilWar1999 — was launched in support of ground forces under Operation Vijay. It aimed to flush out Pakistani regulars and intruders who had occupied Indian positions along the LoC in the Kargil sector. This was the first large-scale use of air power in the Kashmir region since the 1971 Indo-Pak War. Never before had an air force been tasked with such high-altitude precision operations in rugged mountainous terrain—making it a watershed moment in military aviation history. Operation Safed Sagar was a trailblazer in many ways: it saw air power employed in unconventional roles, demonstrated the effectiveness of limited use of air assets in a localised conflict, and shattered the long-held notion that use of air power would inevitably escalate into full-scale war. The operation not only showcased the versatility and resolve of the Indian Air Force but also established the deterrent value of calibrated air strikes—even in a low-intensity conflict. It proved that air power could decisively alter the course of battle without crossing international boundaries. #IndianAirForce #OpSafedSagar #IAFHistory #IAF रक्षा मंत्री कार्यालय/ RMO India Ministry of Defence, Government of India HQ IDS ADG PI - INDIAN ARMY IN

Bernoulli’s Equation: P + ½ρv² + ρgh = constant Mind-bending science that looks like pure sorcery! A lightweight paper loop floats and dances in a high-velocity air stream, seemingly defying gravity. Fast-moving air over and around the loop creates a low-pressure zone above and along its curved surfaces. Higher atmospheric pressure underneath pushes it upward, trapping it in the airstream. The Coanda Effect makes the air hug the curve of the loop, keeping the airflow attached and giving it remarkable stability. Gravity pulls down, while the pressure difference lifts up — creating a beautiful dynamic equilibrium. With nothing but moving air molecules, you can guide the loop wherever you want. Invisible forces at work!
