🚨BOMBSHELL: New FOOTAGE From The Butler Rally Shows A Secret Service Agent Clearing the "Kill Zone" Behind Trump BEFORE The Shots—Was There Foreknowledge? 🕵️‍♂️🏟️ A chilling new video has surfaced from the July 13th Butler rally, taken from just two rows behind the temporary security railing. This 4K close-up captures a moment the "official" narrative simply cannot explain. In the clip, a Secret Service agent is seen calmly but firmly directing people who were standing in the secure area directly behind the stage—and directly behind President Trump—to move to the right side. According to the DOJ and the FBI, Thomas Crooks fired from an elevated rooftop in front of the stage. The trajectory of those shots was downward toward the podium. Anyone standing behind Trump was in the direct line of fire. The Question: Why was this agent clearing the "kill zone" BEFORE a single shot was fired? If the Secret Service was as "surprised" as they claimed, why was there a tactical effort to move civilians out of the line of sight of the AGR building moments before the "lone wolf" opened fire? Did this agent have foreknowledge of the incoming fire? Was the area being cleared to protect the crowd, or to ensure a "clean" field for what was about to happen? Why has this specific movement of people never been mentioned in the congressional hearings? We’ve been told it was a "communication failure." We’ve been told the roof was "too sloped" for a sniper. But we are watching a professional agent act on information that—according to the official timeline—he shouldn't have had yet. This footage is a massive piece of the puzzle. It suggests that at least some elements on the ground knew exactly when and where the threat was coming from. Watch the agent. Watch the crowd. Stop letting them tell you what your own eyes can see. 👁️🕵️‍♀️ From: Wild Videos

ASTEROID 2024 YR4 MAY HIT THE MOON—AND SCIENTISTS ARE HOPING IT DOES A once-alarming asteroid is now offering a unique lunar science opportunity. Asteroid 2024 YR4, once feared to hit Earth, now poses no threat to our planet—but it might collide with the Moon. The 197-foot-wide space rock, tracked by the James Webb Space Telescope, now has a 2% chance of impacting the Moon, according to new data. Scientists say the impact would be harmless to Earth but groundbreaking for research. Julia de León, planetary scientist: "Honestly, I hope it does." If it strikes, it would mark the first time a 60-meter object has been observed slamming into the Moon live. Source: NASA Asteroid Watch

SOUND ON. You’re hearing the first howl of a dire wolf in over 10,000 years. Meet Romulus and Remus—the world’s first de-extinct animals, born on October 1, 2024. The dire wolf has been extinct for over 10,000 years. These two wolves were brought back from extinction using genetic edits derived from a complete dire wolf genome, meticulously reconstructed by Colossal from ancient DNA found in fossils dating back 11,500 and 72,000 years. This moment marks not only a milestone for us as a company but also a leap forward for science, conservation, and humanity. From the beginning, our goal has been clear: “To revolutionize history and be the first company to use CRISPR technology successfully in the de-extinction of previously lost species.” By achieving this, we continue to push forward our broader mission on—accepting humanity’s duty to restore Earth to a healthier state. But this isn’t just our moment—it’s one for science, our planet, and humankind. All of which we love and are passionate about. Now, close your eyes and listen to that howl once more. Think about what this means for all of us.

The “final nail in the coffin" for Russia’s energy influence in the Middle East: Iraq nationalises Russia's Lukoil oil field. Iraq has moved to nationalise Lukoil’s West Qurna-2 oil field, dealing a major blow to Russia’s energy revenues, Reuters reports. The company’s largest overseas asset had been bringing in an estimated $1.5–2 billion in net profit each year. Its loss is set to cost Russia’s budget tens of billions of rubles in missed income. Remember all that talk from Moscow about a "New World Order"? About how the "Global Majority" was going to stick together and move away from the West? Well, Iraq just hit the "Delete" button on that fantasy. For years, we were told Iraq was a key Russian partner. But the second the U.S. tightened the sanctions "handcuffs," Baghdad threw Russia under the bus to save its own bank account. And who did Iraq invite to take over? ExxonMobil and Chevron. Yes, the American "giants" Russia has been trying to replace for a decade are now walking back in to take the loot. This event isn't just a business deal gone wrong. It’s a collapse of the "alternative world order" that Moscow has been trying to build. Remember a month ago, when putin told the Iraqi President that their relationship has "never had a dark moment"? 🤡 “I fully agree with you: our relations are deep and long-standing. And throughout their entire history, there has never been a dark moment," putin told Rashid during talks in Turkmenistan on December 12, 2025. #Russia #Iraq #OilPolitics #GlobalMajority #Exxon #Chevron

🚨 ANOTHER BRAND NEW VIDEO DIRECT FROM IRAN: The campaign has escalated to targeting regime mosques. The Iranian people want to be armed to fight back against a brutal regime, and the videos keep coming. Ordinary citizens inside Iran are sending a steady stream of these videos directly to me, risking everything to break through the silence. This latest footage was sent to me straight from Kish Island in the Persian Gulf. Operating under the cover of night, the man in this video has escalated the campaign in a massive way. If you look closely at the building, he targeted a state-controlled mosque and a known hub for regime propaganda. He isn't just holding up a handwritten manifesto declaring "Iranians demand arms for freedom" alongside the name of King Reza Pahlavi. You can hear him whisper "Javid Shah" (Long Live the King) into the dark as the camera reveals he has spray-painted the exact demand, "ARM US," directly onto the regime's infrastructure. Defacing a state religious building with a demand for weapons is an automatic death sentence, but he is doing it anyway. For the millions they represent, arming themselves is now a tactical necessity for survival. Peaceful protest against live ammunition has proven impossible. They aren't asking for foreign boots on the ground; they are asking for the basic means to fight back against a systemic slaughter. And let’s be clear: the only viable path to effectively arming the Iranian people is through direct coordination with Prince Reza Pahlavi and his team. He risked his life in the dark to deliver this proof straight from the ground. More people need to amplify their calls. Do not let the regime bury his bravery.

🚨 A SATELLITE JUST REVEALED SOMETHING SHOCKING: GPS JAMMING IS FAR MORE WIDESPREAD THAN ANYONE REALIZED. An experimental navigation satellite called Pulsar-0, flying just 500 km above Earth, has mapped GPS signal tampering from space for the first time and the scale surprised even the engineers who built it. As soon as the satellite passed over Europe and parts of the Middle East, its GPS receiver showed massive signal degradation. In the worst areas, signal strength dropped from a normal 40 decibels all the way down to just 10 decibels. Why this matters: • Ground-based jammers (used in conflicts like Ukraine and the Middle East) are now reaching all the way into low Earth orbit • Satellites like Starlink that rely on GPS for collision avoidance and positioning are being affected across a huge region from France to the borders of Pakistan • When GPS drops out, satellites can’t accurately point their antennas, maintain formation, or safely maneuver • This isn’t just a military problem it threatens the growing network of commercial satellites we increasingly depend on The deeper implication: We’ve long known that GPS signals on the ground can be jammed. What we didn’t fully appreciate is how far those jamming signals reach into space. Even satellites in low Earth orbit the backbone of global communications, Earth observation, and future mega-constellations are now operating in an increasingly hostile electromagnetic environment. Xona’s upcoming constellation aims to fix this with signals 100 times stronger than traditional GPS. But the bigger question remains: as more nations and groups weaponize jamming and spoofing, how resilient will our orbital infrastructure actually be? How concerned are you that GPS jamming is now reaching into space and affecting satellites? Follow for more frontier space technology and the hidden vulnerabilities of our orbital systems.

[Discrete Fourier Transform] by Hand ✍️ In signal processing, the Discrete Fourier Transform (DFT) is no doubt the most important method. But the math involved is extremely complex, literally, involving a summation over a complex number term e^(-iwt). I developed this exercise to demonstrate that underneath such complexity, DFT is just a series of matrix multiplications you can calculate by hand. ✍️ Once you see that, it should not surprise you that a deep neural network, which is also a series of matrix multiplications, with activation functions in-between, can learn to perform DFT to process and analyze signals so effectively. How does DFT work? [1] Given ↳ Signals A, B, and C in the 🟧 frequency domain: ◦ A = cos(w) + 2cos(2w) ◦ B = cos(w) + cos(3w) + cos(4w) ◦ C = -cos(2w) + cos(3w) ◦ Each signal is a weighed sum of four cosine waves at frequencies 1w, 2w, 3w, and 4w. ◦ We will apply Inverse DFT to convert the signals to time domain representations, and then demonstrate DFT can convert back to their original frequency domain representations. ↳ Signal X in the 🟩 time domain. X is sampled at 10 time points 1t, 2t, …, 10t: ◦ X = [-2.5, -1.8, 3, -0.7, -1.0, -0.7, 3, -1.8, -2.5, 5] ◦ Suppose X is also a weighted sum of the same four cosine waves, but we don’t already know their weights. We will apply DFT to discover them. [2] 🟧 Frequency Matrix (F) ↳ Write the coefficients of A, B, C as a matrix F. Each signal is a row. Each frequency is a column. ↳ A → [1, 2, 0, 0] ↳ B → [1, 0, 1, 1] ↳ C → [0, 1-, 1, 0] [3] Cosine → Discrete ↳ Sample from the continuous cosine waves at discrete time points 1t, 2t, 3t, to 10t. [4] Cosine Matrix (W) ↳ Write the samples as a matrix, Each frequency is a row. Each time point is a column. [5] Inverse DFT: 🟧 Frequency → 🟩 Time ↳ Multiply the frequency matrix F and the cosine matrix W. ↳ The meaning of this multiplication is to linearly combine the four cosine waves (rows in W) into time-domain signals (rows in T) using the weights specified in F. ↳ The result is matrix T, which are signals A, B, C converted to the time domain. Each signal is a row. Each time point is a column. [6] Transpose ↳ Transpose T, converting each signal’s time domain representation from a row to a column. [7] DFT: 🟩 Time → 🟧 Frequency ↳ Multiply the cosine matrix W with the transpose of matrix T. ↳ The purpose of this multiplication is to take a dot-product between each time-domain signal (columns in the transpose of T) and each cosine wave (rows in W), which has the effect of projecting the signal onto a cosine wave to determine how much they are correlated. Zero means not correlated at all. ↳ The result is an intermediate version of the “recovered” frequency matrix where each column corresponds to a signal and each row corresponds to a frequency. ↳ Compared to the original frequency matrix F, this intermediate matrix has non-zero weights in the correct places, but scaled up by a factor of 5 (n/2, n=10). For example, signal A, originally [1,2,0,0], is recovered at [5,10,0,0]. [8] Scale ↳ Multiply each value by 2/n = 1/5 to scale down the intermediate matrix to match the magnitude of the original frequency matrix F. [9] Transpose ↳ Transpose the recovered frequency matrix back to the same orientation of the original frequency matrix F. ↳ Like magic 🪄, the result is identical to the original F, which means DFT successfully recovered the frequency components of signals A, B, C. [10] Apply DFT to X: 🟩 Time → 🟧 Frequency ↳ Now that we have some confidence in DFT’s ability to recover frequency components, we apply DFT to X’s time-domain representation by multiplying W with X. ↳ The result is the an intermediate matrix. [11] Scale ↳ Similarly, we scale down by a factor of 5 to obtain the recovered frequency components of X (a column). [12] Transpose ↳ Similarly, we transpose the recovered column to row to match the orientation of the frequency matrix. ↳ Using the coefficients [0,0,3,2], we can write the equation of X as 3cos(3w) + 2cos(4w). Notes: I hope this by hand exercise helps you understand the essence of DFT. But there is more technical details, such as: • Sine: The complete DFT math also includes sine waves that follow a similar calculation process. • Phase: Here, we assume all the cosine waves are aligned at the origin, namely, phase is 0. If a phase p is added, for example, cos(w+p), we will need to calculate the sine component and use their ratio to figure out what p is. • Magnitude: If phase is not zero, the magnitude will need to be calculated by combining both cosine and sine terms.

The Earth Has Something to Say Somewhere on the Namibian savanna, a herd of elephants stops. No signal you can hear. No movement you can see. They simply freeze, as if the world pressed a pause button. Then, almost imperceptibly, several of them lean forward onto their toes. They are listening. Just not with their ears. When an elephant rumbles, a replica of that sound is simultaneously transmitted through the ground, travelling as a seismic wave at roughly 250 meters per second. It is inaudible to us. It is inaudible, for that matter, to most of life on Earth. But an elephant is not most of life on Earth. The soles of an elephant’s feet contain densely packed Pacinian corpuscles, mechanoreceptors so sensitive they are thought capable of detecting movement as subtle as Brownian motion. The tip of the trunk has them too. The animal is, in effect, a walking seismograph, designed by evolution over millions of years to read the planet’s whispers. Researcher Caitlin O’Connell-Rodwell first noticed this while watching herds at a watering hole in Etosha National Park in 1992. Suddenly the entire herd would freeze, ears flat to their heads, each enormous animal leaning forward on tiptoes, sometimes raising one foot. This, she eventually realised, was not confusion. It was concentration. What makes it stranger still is that the system has a caller ID function. When O’Connell-Rodwell played back familiar alarm calls as seismic signals, the elephants froze and bunched together. When she played unfamiliar calls from Kenyan elephants, the same herd was entirely unbothered. They knew the voice. Through the ground. From kilometres away. Seismic waveforms produced by a running elephant can travel up to 32 kilometres, twice as far as the same animal’s airborne calls. On a windy day, when sound scatters and distorts, the ground stays steady. The earth, it turns out, is an excellent telephone line. It has been there all along, faithfully carrying messages between animals that had the good sense to learn to read it. We built the internet. They figured out the planet.

When a spacecraft leaves Earth, it doesn’t just fire its engines and head straight to its destination. In many missions, especially those going beyond low Earth orbit, there’s a more subtle and elegant strategy at play, one that uses gravity itself as part of the navigation system. This is often called a gravity assist, or a slingshot maneuver. But in the case of missions like #Artemis II, what’s being used is a closely related idea known as a free-return trajectory. At first glance, it might sound simple: the spacecraft goes to the Moon, loops around it, and comes back. But the physics behind it is anything but simple. Instead of relying on continuous propulsion, the spacecraft follows a carefully calculated path through the gravitational field of the Earth–Moon system. It is launched with just the right speed and direction so that, as it approaches the Moon, the Moon’s gravity bends its trajectory. The spacecraft is effectively flung around the Moon, redirected onto a path that naturally brings it back toward Earth. No major engine burn is needed for the return. Small trajectory corrections may still be required, but gravity does the heavy lifting. That’s the key. This kind of trajectory is not just efficient, it’s also safe. If something goes wrong with the spacecraft’s engines or onboard systems, gravity itself ensures the return. It’s an inherent backup plan, built into the trajectory from the very beginning. The same fundamental idea appears in gravity assists used across the Solar System. When a spacecraft flies past a planet, it can gain or lose speed by exchanging momentum with that planet. From the spacecraft’s point of view, it’s as if it has been accelerated without using fuel. In reality, it has borrowed a tiny amount of orbital energy from the planet itself. That’s how missions like Voyager reached the outer planets, and how probes continue to explore regions far beyond what their onboard fuel alone would allow. But there’s an important distinction. An interplanetary gravity assist is typically used to change speed and direction, often increasing the spacecraft’s energy. A free-return trajectory, like the one used in Artemis II, is designed for something more specific: a path that naturally loops back to Earth without requiring additional propulsion. It’s less about gaining energy, and more about shaping a trajectory that guarantees a return. To understand why this works, it helps to stop thinking in straight lines. In space, motion follows curves defined by gravity. The spacecraft is constantly falling, first toward Earth, then toward the Moon, and then back toward Earth again. What looks like a loop is really a continuous free fall through a changing gravitational landscape. This way of navigating space reveals something deeper. We tend to think of engines as the drivers of motion, but once a spacecraft is on its way, gravity does most of the work. The art of spaceflight is not just about thrust. It’s about knowing when not to use it. #GoodLuck #Artemis NASA Artemis

🚨 CHINA IS RACING TO BUILD A SPACE SOLAR POWER PLANT THAT COULD BEAM ELECTRICITY FROM ORBIT TO EARTH. Scientists at Xidian University have successfully tested a ground-based system that can wirelessly transmit kilowatt-level power over 100 meters using microwaves. Their ultimate goal is far more ambitious: placing large solar power stations in geostationary orbit (36,000 km up), where sunlight is available 24/7 with no weather or atmosphere blocking it. The project, called Zhuri (“chasing the sun”), uses mirrors to concentrate sunlight onto solar panels, converts the electricity into microwaves, and beams it down to a receiving antenna (rectenna) on Earth. Why this matters: • In space, solar energy is up to 6 times more efficient than on Earth because there’s no night, clouds, or atmospheric filtering • A single large space solar station could theoretically generate gigawatts of continuous clean power enough for millions of homes • The team has already proven the system can beam power to multiple moving targets at once • China is now among the world leaders in this technology, alongside the US and Japan The deeper implication: Space-based solar power has been a dream for decades because it could provide truly baseload renewable energy. While the technical and financial challenges are enormous (building massive structures in orbit, precise microwave beaming, and safety), steady progress like this brings the concept closer to reality. If successful, it could fundamentally change how humanity generates and distributes energy moving power collection off the planet entirely. Near-term applications could include wirelessly charging satellites or powering future lunar bases. Do you think space-based solar power will become a major energy source in the coming decades, or will it stay too expensive and complex? Follow for more frontier energy and space technology developments.

🚨⚠️ I NEED TO SAY THIS, BECAUSE AS SOMEONE WHO LEADS A TEAM, I KNOW EXACTLY HOW THESE THINGS WORK. ⚠️🚨 🩺 As a surgeon, I work every day with teams where every single person plays a vital role. In surgery, the anesthesiologist, scrub techs, assistants, nurses, and specialists each have a precise moment where their work must be seen, executed, and respected for the operation to succeed. If one part fails, the overall execution loses quality. 🎥 And the same applies to a stage performance. 📍There are cameramen positioned at every corner. 📍There are technical directors. 📍There are people coordinating transitions, camera cuts, and screen time. Everything is rehearsed. Everything is planned. Everything follows a script. So explain to me why, when it’s Jimin’s moment to execute his part —his lines, his center, his movements, his expressions— the camera suddenly cuts away, ignores him, or prioritizes other shots instead. 🎭📷 Because this is NOT accidental. ❌ And the fans can SEE IT. 👀 This is not about competing against other members. This is about professional respect for the work of EVERY member of BTS. A perfect performance works like a perfect surgery: ✨ every detail matters, ✨ every contribution matters, ✨ and every professional deserves to be shown at the exact moment their role is meant to shine. Jimin should not disappear from the screen during key moments of his performance. He should not be treated like background noise when he is an essential piece of the entire show. And don’t tell me I’m exaggerating. Don’t tell me everyone is treated equally. Don’t tell me anything at all. 👁️ JUST WATCH. 👁️ And if after watching you still choose to ignore it, then the problem isn’t that it doesn’t exist… the problem is that you refuse to see reality. Because to miss something this obvious, you would have to be completely blind. ⚠️🚨 And THIS is exactly why we, as fans, need to continue elevating Jimin’s music, his image, his artistry, and his impact even louder. 🎶🔥 Stream his music. Support his projects. Talk about his talent. Highlight his performances. Protect his name. Make sure the world sees what some cameras keep failing to show. Because no matter how much they try to minimize his moments… his presence is simply impossible to erase. ✨👑 BIGHIT MUSIC HYBE OFFICIAL WITH JIMIN TILL THE END WE LOVE YOU JIMIN JIMIN JIMIN

What a thrill to watch your child take their first steps. But I want to spotlight something else about this video: the sheer perfection of the support system created by its adults. They teach us a lesson about learning that extends far beyond walking. If you watch closely, you’ll find that mom and grandpa have created a scenario in which baby is challenged to the limits of her ability AND provided the supports needed to guarantee her success. From the moment grandpa lets go, mom’s waiting arms are close enough that baby’s safety is ensured. She literally can’t fall. But watch what mom does as the baby finds success: She slowly retracts her arms and even begins to lean backward ever so subtly - extending baby’s runway while maintaining this safety net. As a result, what might have been journey of 1-2 steps was extended to 5-6. Simply fantastic. This is how all learning takes place: just beyond the limits of our prior success - and with scaffolding from caregivers, teachers, and more capable peers who help propel us just a little bit further than we’ve ever gone before. Is you child working to master something new? How might you adapt the lessons of this video to scaffold their success? 🎥 sean.nicol IG

🚨 NASA JUST FOUND THE RAW INGREDIENTS OF DNA INSIDE A ROCK OLDER THAN EARTH ITSELF. Samples returned from the asteroid Bennu contain complex organic molecules including precursors to DNA and RNA, plus many of the amino acids used by all life on Earth. These molecules formed in the early solar system and survived for billions of years inside the asteroid. Earth didn’t have to invent the chemistry of life from nothing. It was delivered ready-made from space. Why this matters: • Bennu is a primitive asteroid that has remained largely unchanged since the birth of the solar system (~4.5 billion years ago) • The samples contain the molecular building blocks of DNA, RNA, and proteins the core components of life as we know it • These organics were preserved through the violent early days of the solar system and could have been delivered to Earth by asteroids and comets • This is some of the strongest direct evidence yet that life’s chemistry has cosmic origins The deeper implication: This doesn’t mean aliens or microbes came from space. It means the raw materials for life were already floating around the solar system long before Earth cooled enough to support life. Our planet likely received these ingredients from above rather than creating them all from scratch. If these building blocks were common in the early solar system, then the starting chemistry for life may have been widespread dramatically raising the chances that similar processes could have happened elsewhere. How does it change your perspective to know that the molecular ingredients for DNA were already present in space billions of years before the first living cell appeared on Earth? Follow for more discoveries about the origins of life and what we’re learning from asteroid samples.

Did you know that fruits and veggies are picked way earlier than nature intended just to accommodate legacy infrastructure? They’re harvested while still in their infancy just to survive a supply chain that’s been capped by outdated solutions. Produce sits in dark containers and cold storage for weeks, sometimes months, before it ever reaches your kitchen. Harvesting too early is a legacy constraint we’ve accepted for too long. The industry’s "solution" to keep this prematurely picked fruit from rotting has been to coat it in petroleum-derived waxes and synthetic fungicides. We were told that if we want fresh food, we have to accept a layer of plastic-like wax on our apples and cucumbers. Even the "Organic" label has been used as a shield, while still relying on those same, legacy coating methods. There’s room for innovation. The system wasn't built for flavor or nutrients. It was built for a long-haul flight. Our team of scientists and technologists are deploying a new strategy that uses food to protect food. We’ve pioneered a way to take the materials found in the peels, seeds, and pulp of all plants and recycle them into a high-performance shield. By mimicking nature’s own defense system, we’re finally able to harvest for the best consumer experience. That’s the future. We’re allowing fruit to stay on the vine longer, develop real complexity, and reach your table at the peak of its potential. We’re inviting consumers, retailers and suppliers to join us in bringing a new food experience online. Follow James Rogers and Luiz Beling to learn more. Plant-based protection is the future. Apeel forever.

Introducing THE METATRIBES: REBORN REBORN's battle royale mode departs from the conventional, eschewing modern firearms like those found in #Fortnite or #CallofDuty. Instead, players will engage in combat using ancestral weapons, focusing on authentic, melee-based encounters. The gameplay emphasizes strategic positioning, tactical thinking, and mastery of ancient combat techniques, making every battle a test of wits and skill rather than just firepower. This approach invites players into a realm where strategy reigns supreme, and every fight is a dance of survival and cunning.
