This looks like science fiction. A phased ultrasonic array... creates moving pressure points in mid-air at speeds up to 9 m/s with full 360° freedom. LEDs track the acoustic focus, turning invisible sound into floating 3D images. Holograms made from physics, not screens.show more

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!show more

That’s insane! 🤯 A student built an acoustic levitation... divide with an Arduino board. He built it using an Arduino Nano, a motor driver, and 60 ultrasonic transducers that can levitate low-density objects in place indefinitely. The transducers send out 40 kHz waves that create standing waves. The interference pattern produces nulls that trap objects. High-pressure areas form below and above the object, locking it in the low-pressure area between them. The transducers produce two sound waves moving in opposing directions at the same frequency and amplitude. The effect is that the low-pressure areas don't appear to move, like whipping a rope from both ends and having the wave meet in the middle. Sound waves are oscillating at high and low pressures. By creating a sound wave that doesn't move forward (a standing wave), you create areas of constant pressure. 🔉 Objects get trapped in the null points between high-pressure zones. The craziest part is that this was made more than 7 years ago! DIY levitation 😮‍💨 Reddit link: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →show more

THIS SPEAKER HAS NO RIGHT TO BE THIS COOL... It looks like a fancy glass box. Then you plug it in… and boom: lyrics start floating mid-air like a karaoke fever dream.

😡Russians set up giant propaganda screens on border with... Estonia Russia is building a stage and installing massive screens on its side of the Narva River — pointed directly at Estonia — to blast its May 9 “Victory Day” narrative across the border. It’s not a celebration — it’s a performance of militarism aimed at Europe. But here’s an idea: authorities in Narva could respond by setting up their own screens — showing the real outcome of this “victory.” Destroyed Ukrainian cities. Mass graves. Fields full of abandoned Russian soldiers. Let them see what their triumph really looks like!show more

Birdsong is not just sound. It is data made... physical. If you could see the air at the exact moment a hemp bunting sings, you would not see empty space. You would see a structured three-dimensional data array. What we hear as a soft “chirp” can be mapped as frequencies, rhythms, amplitudes, and harmonic relationships. A scatter plot turns a fleeting song into a topographic map of sound. And the technical beauty is remarkable: → Sound is a mechanical wave, built from compressions and rarefactions in the air. → The bird controls it through the syrinx, a vocal organ capable of generating two frequencies at once. → Frequency shapes pitch. → Amplitude shapes volume and cluster density. → Timbre creates the unique waveform, the texture of each “sound island.” → Each cluster shows the acoustic proximity of syllables and motifs. What looks like chaos is not chaos. It is a bioengineered signal. Territory. Genetic profile. Hormonal state. Aggression level. Mating fitness. All encoded into patterns of pitch, timing, volume, and timbre. This is why I find it so fascinating. A bird is not simply singing into the air. It is organizing the air. It is carving space into sectors of influence using sound pressure. It is making a physical claim to territory. For some, birdsong is peaceful background music. For others, it is a complex mathematical model calibrated by millions of years of evolution for survival. And here is the urgent lesson for the AI age: We often mistake invisible systems for simplicity. A bird sings, and we hear romance. An AI responds, and we see magic. But underneath both are signals, compression, feedback loops, optimization, and information architecture. The future belongs to those who can read what others dismiss as noise. So I’ll ask you: When you hear birdsong, do you hear music, data, or both? #AI #ArtificialIntelligence #Bioacoustics #Nature #Technology #Data #MachineLearning #Innovation #FutureOfWork #Signals #Evolutionshow more

So this is what “freedom of speech” looks like... in West Bengal— A young girl in Ashoknagar posts about the #PahalgamTerrorAttack. She’s met with rape threats. Her video goes viral. And then—like a scene from a dictatorship—the local OC lands at her house at midnight to silence her. Today I met this brave yet terrified girl and promised her NCW s full support. Free speech? Only if you toe the line. Otherwise, threats, fear, and midnight knocks. #Ashoknagar #WestBengal #RightToSpeak #Shameful #WomenSafetyshow more

🚨 FOOTAGE EMERGES OF THAI AIRFORCE STRIKES ON CAMBODIAN... MILITARY POSITIONS 🚨 New battlefield video now confirms Thai Air Force jets conducting strike runs against Cambodian military positions along the border — marking the clearest escalation yet in this fast-moving conflict. Multiple passes can be seen, with explosive impacts on dug-in fortifications and supply points on the Cambodian side. This appears to be Thailand’s first verified use of airpower in the current standoff. What began as cross-border shell exchanges has now shifted into full aerial engagement — a major turning point. This development raises urgent questions: • How will Cambodia respond? • Will their Chinese-supplied air defense systems come into play? • Will Thai mechanised units advance under cover of air strikes? • Does this open the door to wider regional involvement? With armour already moving, artillery trading across the border, and civilian evacuations now increasing, this conflict is rapidly transitioning from skirmish to structured warfare. Tonight, escalation is no longer hypothetical — it is happening in real time.show more

🇺🇸 ELON TEASES FLYING TESLAS...WAIT...WHAT?! Elon said the next... Tesla sports car could do more than just break speed records; it might actually fly. In a recent interview, he teased “crazy technology” that could include rocket thrusters and flight features that sound closer to science fiction than street legal. Nothing's confirmed yet, but the idea lines up with Tesla’s habit of pushing boundaries. Yes, we might not be far from the car that takes autonomous driving off the road and into the sky. Now imagine this: you hop in, Grok says hello, maps your air route, adjusts the cabin for flight mode, and loads up a voice companion from Tesla Ride to keep you company while cruising 500 feet above traffic. We're not just talking about cars at Tesla anymore; we're starting to ponder pilotless jets with personalities. Source: Open Toolsshow more

Israel is quietly developing technology that could make the... 2024 The Mossad: Satirical and Awesome pager operation in Lebanon look like child’s play. Picture this: Invisible nanobots slip undetected into a target’s body through water, food, or even air. They remain completely dormant, harmless, and untraceable for weeks, months, or even years… until a remote signal (ultrasound, magnetic field, or other trigger) wakes them on command. They activate from the inside with surgical precision, neutralizing the threat with zero explosion, zero collateral damage, and zero warning. The real foundation already exists in Israeli labs. Technion researchers have created sugar-coated “sleeping” nanoparticles for sonodynamic therapy. These particles accumulate in targeted tissue, stay inactive until triggered by low-intensity ultrasound, then destroy cells from within with minimal toxicity. This isn’t science fiction anymore. It’s Israeli innovation turning the human body into a programmable precision weapon. From the lab to potentially redefining counterterrorism and medicine worldwide. Startup Nation at it again.

✨ Made a new mini feature on Photo AI:... [ Grab from 3d model ] So the problem is we're at that stage in time (typical for AI) where image-to-3d models are not good enough but are fun to play with, but we know they'll be good enough in 1-2 years With [ Make 3d model ] you already can turn any Photo AI pic into a 3d model but it still looks hyper clunky and deformed, but it works! One cool idea I had to make that more useful and made now: Let people make a 3d model then change the view of the it with the 3d viewer, then press [ o ] and it grabs a frame of the 3d That image you can then [ Remix ] (img2img), and it becomes a real photo again and that in turn you can then turn into a video again with [ Make video ] So that essentially gives you a fully freeform camera position control to take photos with One thing I need to fix is the background/skybox, I kinda need to take the original photo and remove the person and just get the background for the 3d model viewer, in this case it should be white, but it's a start!show more

📺 China’s Flying TV is here — and it’s... mind-blowing. 🤯 I still can’t get over this. A drone-powered LED display that hovers mid-air, turning the sky into a living, moving screen. Not a drone. Not a billboard. Something entirely new. This is both — fused, intelligent, and powered by AI. 🇨🇳 What makes it so impressive: ➡️ Ultra-light LED screen with HD visuals ➡️ Balanced in flight by AI-driven gyroscopes ➡️ Smooth, stable, and autonomous flight control ➡️ Operates remotely or follows programmed paths It’s powered by lithium-polymer batteries, yet looks effortless as it floats — like it belongs there. 🎯 Possible use cases: open-air concerts, sports arenas, public messages, or next-gen sky advertising. To me, this is where AI starts to move beyond function — into wonder. It’s not just about smarter machines, but about reshaping how we experience technology itself. 👀 The next screen you look at might not be on a wall… it might be in the sky. #AI #Innovation #Technology #Drones #FlyingTV #Automation #Creativity #FutureOfWork Credits: Olivier Gomezshow more

🚨 CHINESE SCIENTISTS JUST INVENTED 3D PRINTING THAT CREATES... OBJECTS IN 0.6 SECONDS USING ONLY LIGHT. Researchers at Tsinghua University have developed a new method called DISH (Digital Incoherent Synthesis of Holographic light fields) that can print complex millimeter-scale objects almost instantly. Instead of slowly building layer by layer, the system fires thousands of precisely patterned light images from multiple angles into a still vat of liquid resin. Where the light overlaps, the resin instantly hardens into a solid 3D object. The entire process takes just 0.6 seconds. Why this matters: • It’s currently the fastest volumetric 3D printing method ever demonstrated • Achieves extremely fine detail features thinner than a human hair • The resin stays completely still, so there’s no vibration or distortion • It can work with watery (low-viscosity) resins, making it suitable for biological applications • The team has already printed complex structures like blood vessel-like tubes and even a tiny bust of a historical figure The deeper implication: Traditional 3D printing has always been limited by speed and the need to move either the print head or the resin. This approach removes both constraints by using light itself as the sculptor. Because it can print directly into still liquid (and potentially onto living tissue), it opens new possibilities in bioprinting, medical devices, and rapid manufacturing. If the technology can be scaled beyond millimeter sizes, it could fundamentally change how we think about making physical objects turning “print” from a slow process into something closer to instantaneous fabrication. We’re moving from “layer by layer” to “all at once.” How do you think instant volumetric 3D printing like this could change medicine, manufacturing, or everyday life if it becomes widely available?

🚨 SCIENTISTS JUST BROKE A 30-YEAR SUPERCONDUCTIVITY RECORD. Researchers... at the University of Houston have created a material that carries electricity with zero resistance at 151 Kelvin (−122°C) under normal atmospheric pressure. That may not sound dramatic… until you realize it’s the closest anyone has ever come to the holy grail of materials science. Why this matters: Superconductors eliminate energy loss as heat. Right now, power grids waste enormous amounts of electricity just moving it around. This breakthrough could mean: •Dramatically more efficient power grids • Better fusion reactors • Faster, cooler electronics • More powerful MRI machines • Next-generation quantum computers Most importantly: the material stays superconducting even after the pressure is removed. The deeper implication is huge: For 30 years the record stood. Now it’s fallen and we’re one major step closer to room-temperature superconductivity. The dream of power lines with literally zero energy loss may no longer be science fiction. What technology changes first if we finally achieve room-temperature superconductors?

Blessed Easter from occupied Jerusalem to the world This... is what #Easter looks like in occupied #Jerusalem. Behind metal barricades and under the watch of heavily armed police, Palestinian Christians — along with international pilgrims — are prevented from freely reaching the Church of the Holy Sepulchre. Among them are peaceful citizens holding candles, simply wishing to pray, to walk the path of Christ, and to mark the resurrection in the very city where it happened. They come with faith, not fear. With candles, not conflict. And yet they are treated as a threat in their own homeland. The images capture more than a moment — it reflects a system of control that turns faith into friction, prayer into protest, and Easter into an act of resistance. But even behind barriers, the light carried by these worshippers still shines. Light must prevail over erasure. Over exclusion. Over military occupation. Freedom of worship is a basic human right. In Jerusalem, it’s time the world stands up for it. Palestinian Christians, like all Palestinians, deserve to live and worship in peace, dignity, and freedom. Israeli military occupation must end. #Jerusalem #Easter2025 #FreePalestine #ChristianPalestinians #FreedomOfWorship #ReligiousFreedom #EndTheOccupation #EndIsraeliSettlerColonialism #EndTheOccupation #EndIsraeliApartheid #EndIsraeliImpunity #LightWillPrevailshow more

If you typically stream with a 3D model, I... highly recommend that you pose your model when you’re not doing full body mocap instead of letting it stay in the stiff generic pose! It makes a huge difference in how your energy is conveyed (ᗒ⩊ᗕ)⸝ި ʕᦏ⌎ I’m only saying this because I noticed this a lot with my own 3D kids, but here’s a comparison showcase: ← default pose & default pendulum physics in Warudo → custom poses & slightly adjusted pendulum physics If you find it hard to pose within Warudo by using bone offsets or none of the existing poses in Warudo vibe with you, you can make your own like me! I made my custom poses in “VRM Posing Desktop” (this is the BEST vrm posing app I’ve ever used in the past 3 years) and exported them as Unity anims then dropped them into Warudo’s animation folder! You can then make a simple blueprint in Warudo to toggle between poses and make your model look more alive! It should fit especially well for just chatting streams 🙂‍↕️✨show more

The fascinating concept of Non-Newtonian fluids, which transition from... a liquid state to a solid-like state when pressure is applied, has a rich history that spans several centuries. The study and understanding of these peculiar fluids have evolved over time, leading to a wide range of practical applications and scientific insights. One of the earliest references to Non-Newtonian behavior in fluids dates back to the 17th century when Sir Isaac Newton formulated the basic principles of fluid mechanics. Newton's laws of fluid motion primarily applied to Newtonian fluids, which exhibit constant viscosity and flow behavior regardless of the applied force or pressure. However, it soon became apparent that not all fluids behaved in this predictable manner. In the mid-19th century, a scientist named Thomas Andrews made significant contributions to the understanding of Non-Newtonian fluids. Andrews conducted groundbreaking experiments with carbon dioxide, revealing that under high pressure, this gas could transform into a liquid. This observation marked one of the earliest instances of pressure-induced phase changes in fluids. The term "Non-Newtonian" itself was coined in the 20th century to describe fluids that did not adhere to Newton's classical laws of fluid dynamics. These fluids exhibited a variety of behaviors, but one of the most intriguing was their ability to solidify or increase in viscosity when subjected to stress or pressure. One of the most famous examples of such behavior is cornstarch mixed with water, which forms a substance known as "oobleck" that becomes more solid when pressure is applied. In the modern era, Non-Newtonian fluids have found applications in various fields, including food science, engineering, and material science. They are used in products like quicksand, body armor, and even in the development of impact-resistant materials. One of the key insights that emerged from the study of Non-Newtonian fluids is the importance of understanding the relationship between stress and strain, as well as the influence of time-dependent properties on their behavior. This knowledge has led to advancements in rheology, the study of flow and deformation in materials, and has practical implications in areas such as industrial processing, medicine, and the design of everyday products.show more
