🇷🇺🔥 Russian combat laser destroys drone at 1.5 km distance in tests 🔸The working distance of the Posokh laser system developed by LazerBuzz company has been increased by 0.5 km, its developers state, with a fixed-wing FPV UAV successfully destroyed during a mock attack. 🔸The Posokh system is a Russian laser weapon designed to combat aerial targets to protect industrial and critical infrastructure facilities. 🔸It has an integrated radar system and can destroy targets in less than 0.5 seconds, including in automatic mode. 🔸The system operates by physically impacting the UAV based on focused ytterbium laser radiation technology, with the ray power reaching 80kW.

44 million birds crossed Kentucky last night. Another 42 million crossed Tennessee. A lot of y’all said those radar blooms couldn’t be birds. They were. Radar sends out two signals, one horizontal and one vertical. Rain reflects them almost the same. Birds don’t. That’s why storms in South Dakota showed up purple, while the birds over Kentucky showed up orange. And the reason the blooms hug the radar sites? The beam gets higher the farther it travels. Most migrating birds are only a couple thousand feet up, so radar sees them best nearby.

Ukraine's 429th Achilles Brigade says it established fire control over Russia's Millerovo airfield, 170 km from the line of contact. A RAM-2X loitering munition covered the distance and successfully struck a Nebo-U radar while a reconnaissance UAV observed the attack. The unit said the radar was not completely destroyed but was damaged, assessing that even partial damage could take it out of service for at least 3-6 months. Russian forces also launch Shahed drones from the airfield. #Ukraine

🚨 SCIENTISTS JUST DETECTED QUANTUM ENTANGLEMENT IN A CENTIMETER-SIZED PIECE OF METAL SOMETHING ONCE THOUGHT IMPOSSIBLE AT THIS SCALE. Researchers at the Vienna University of Technology have found clear evidence of high-degree quantum entanglement among particles inside a macroscopic crystal of a “strange metal” made of cerium, palladium, and silicon. This is one of the first times multipartite entanglement has been convincingly demonstrated in a solid object large enough to hold in your hand. Strange metals are already bizarre their electrons don’t behave like normal individual particles. Now it appears large numbers of them can act as a single, highly entangled quantum system even at everyday scales. Why this matters: • Quantum entanglement has almost always been limited to tiny numbers of particles in carefully isolated lab conditions • This experiment shows entanglement can persist collectively across a visible, macroscopic object • It was measured using neutron scattering, which revealed the material responding as one entangled system rather than many independent particles • This bridges the gap between microscopic quantum effects and real-world materials The deeper implication: For decades, physicists have wondered whether the strange, collective behavior seen in certain quantum materials could be explained by underlying entanglement. This result strongly suggests the answer is yes even at scales we can see and touch. It doesn’t mean your coffee mug is in a quantum superposition, but it does show that quantum correlations can dominate the physics of certain solids in ways we’re only beginning to understand. This kind of macroscopic quantum behavior could eventually help us design new materials with exotic properties, or give us new tools to study fundamental questions about quantum mechanics itself. How do you think discovering entanglement at this scale changes our understanding of where the quantum world ends and the classical world begins?

China has unveiled a spheric police robot capable of pursuing criminals. The AI equipped robot can operate autonomously. It can even fall from heights. The robot is capable of confronting perpetrators, shooting nets to immobilise them until police arrive. It attacks opponents at speeds of up to 35 km/h.

Russia presented two "Russian" cars at the St Petersburg Economic Forum which turned out to be overpriced Chinese vehicles. A new "Volga" was presented that turned out to be a rebadged Geely Monjaro. The "Volga" costs 4.2 million rubles and more, while the Geely Monjaro costs about 1.5 million rubles in China. The new Aurus Senat 900 has turned out to be a copy of the Hongqi H9. Russians are being asked to pay 10-12 million rubles for it, while the Chinese original can be bought for around 4 million rubles. The "Russian spirit" comes at a cost, apparently.

Look closely at a roughly $109 million F-35B and the remarkable feature is what you barely see, fastener heads, wide panel gaps or steps between sections. That apparent single shell contains more than 40,000 threaded fasteners and over 1,000 measured seams in between panels. Despite weighing up to 27 tons and measuring 15.6 m long with a 10.7 m wingspan, the F-35B has an estimated frontal radar cross section of just 0.001 m², roughly a metal golf ball once in the air. Even advanced airborne AESA fighter radars and ground based long range SAM engagement radars like the S400 system, typically cannot detect or lock it until within 25-40 km, making long range air-to-air or surface to air missiles extremely hard to employ against it. Radar does not see a “smooth”surface as we do. The aircraft’s shape redirects energy away, while low observable materials absorb part of it. But a single raised fastener head, open or uneven panel gap or small step becomes a new edge or cavity that creates a radar signature. It disrupts electrical currents across the surface and can scatter energy back which advanced radar can pick up. Composite skins are formed on precision tools that set the exterior contour, then drilled to fit the structure beneath. The fasteners are not hidden inside, countersunk heads pass through the skin, are set flush or recessed, measured, filled until the curve is restored, and measured again. Exact F-35 tolerance limits are not public, but the inspection tool repeats to better than 0.001 inch, about 25 micrometres. Seams are separately checked for gap and vertical mismatch, conductive gap fillers and low-observable coatings help stop those transitions becoming strong reflectors points. Fourth-generation fighters already used flush fasteners for reducing aero drag. The real fifth-generation leap is treating every minute seam, material change and removable panel as radar geometry, then reproducing that finish across a fleet. At sea, salt, moisture, fluids and panel removal make preserving it a permanent maintenance discipline. A stealth outline can be copied from a photograph. The real manufacturing capability is making tens of thousands of parts and panels behave like one electromagnetic surface and restoring it for decades. Source, Pacific Airshow

🚨 BREAKING NEWS 🚨 SCIENTISTS JUST TELEPORTED QUANTUM INFORMATION THROUGH THE EXISTING INTERNET. Not in a lab vacuum. Not through a special quantum-only cable. They did it through real internet fiber while normal internet traffic (400 Gbps) was still flowing. Researchers at Northwestern University successfully transmitted a quantum state of light across 30 km of active fiber optic cable, proving quantum signals can coexist with the classical internet we already use. Why this matters: Today’s internet moves classical bits. A quantum internet could enable virtually unhackable communication, distributed quantum computing, and ultra-secure networks. Quantum information cannot be copied without disturbing it a built-in security feature. The deeper implication: The internet may evolve from moving classical information into moving quantum states themselves. At that point, the line between communication and computation begins to disappear. We may be watching the early construction of an entirely new layer of civilization.
