The US recorded something strange underground and didn’t know what it was. Now he has just accused China of pressing the nuclear button

by

During the Cold War, even at times of greatest nuclear tension, Washington and Moscow maintained an unwritten rule: If a test was done, the world had to find out. The explosions were political signals as much as military experiments, designed to be seen, measured and, of course, feared. Therefore, talking about detonations so small that they barely leave a seismic trace and about tests designed not to be detected, generates great concern. The United States just accused China exactly that. An unprecedented accusation. It happened last Friday, when the United States denounced China for having carried out at least a nuclear test with explosive performance in 2020 and to prepare for other low-power ones, a complaint made in Geneva through by Undersecretary Thomas DiNanno just as the classical arms control framework is collapsing after the New START expiration. According to Washington, Beijing would have resorted to decoupling techniques to dampen seismic signals and hide underground detonations, an accusation of enormous political significance because it breaks the previous ambiguity and indicates for the first time a specific date, the June 22, 2020in the midst of debate over whether the United States should recover the option of testing nuclear weapons again. The diffuse limit. The technical and legal background is key to understanding the controversy, since both China and the United States have signed, but not ratified the Comprehensive Nuclear Test Ban Treatyallowing subcritical testing no self-sustaining nuclear reaction but prohibits any explosion with measurable output. Washington maintains that Beijing would have crossed that line with evidence very low powerdifficult to detect, while the body in charge of verification, the Comprehensive Nuclear Test Ban Treaty Organization, ensures that its network did not detect no event compatible with a nuclear explosion that day, thus underlining the fragility of a control system that never came into full force. Lop Nur, satellites and silent expansion. It we have counted other times. American suspicions are also supported by satellite images and intelligence analysis that point to intense activity in the historic Lop Nur polygonwith new excavations, tunnels and drilling that could be used for both subcritical tests and higher performance detonations. This movement fits with the rapid expansion of the Chinese arsenal, which would already exceed the 600 nuclear warheads and could reach a thousand before 2030reinforcing the perception in Washington that the real strategic challenge is no longer Moscow but a Beijing with the capacity and will to challenge US military primacy. A new nuclear race scenario. The Washington complaint comes accompanied by a clear political message: without binding limits, transparency or verification mechanisms that include China, the system inherited from the Cold War ceases to serve, and the United States reserves the right to adopt “parallel steps”including the resumption of testing, if it considers that other actors are breaking the rules. Beijing strongly rejects accusations, claims its moratorium and its doctrine of no first use, but the simple verbal clash shows a change of phase, one with the risk that the end of New START and mutual distrust open the door to a new nuclear race in which small, almost invisible explosions can have enormous strategic consequences.

The most famous bridge in the US recorded more than 2,000 suicides. Until in 2024 they found an “invisible” solution

by

When the golden gate Opened almost a century ago, it was celebrated as an architectural triumph of engineering and modernity. It happens that the history of many of the great works has had a second reading. Sometimes they have failed due to technical problemsand others have ended up marked by uses that no one foresaw. Over time, a bridge can become something very different from what its plans imagined. The bridge and its dark history. The Golden Gate Bridge, inaugurated in 1937 between San Francisco Bay and the Pacific, has been for decades one of the places most associated to suicide in the United Stateswith a rate of more than 2,000 jumps confirmed and a real figure surely higher because not all cases are seen nor all bodies are recovered. In 2006 there was one of the worst years, with at least 34 deathsand that was also the turning point in which relatives of victims, as Paul Mullerdecided that it was unacceptable to continue living with that routine of tragedies without a physical and effective response on the bridge itself. The barrier that changed destiny. The solution ended up being a deterrent system “invisible” installed along both sides of the bridge, one based on stainless steel cables of marine grade placed about six meters below the pedestrian walkways. It is not something that can be seen from afar or from normal traffic, but it is evident to those who look over the edge. The idea is simple and tremendous at the same time: if someone tries to jump, they fall on that structure, are injured or shocked, and the possibility of completing the fatal fall into the water is cut off. The barrier created to prevent suicides The effectiveness of the new impact. For many years the Golden Gate recorded an average of about 30 deaths annuallya figure that seemed entrenched and almost impossible to break. However, in 2024, with the facility entering its final phase and with adjustments still underway, the deaths they went down to eight. Last year, in 2025 and with the system already operating for twelve months, there were only four and there were no falls between June and December, a stretch that could be one of the longest without suicides on the bridge, although old records are not always complete. By the way, from the beginning of 2026 there is already a casewhich reminds us that there is no such thing as zero risk. That said, the general decline is so evident that even its promoters see it as clear proof of effectiveness and a mirror for the rest of the hanging architectures. Surveillance and intervention. The barrier does not act alone, because the bridge maintains an electronic surveillance system and a team of agents whose task is to detect and stop attempts before they occur. In the last year, 94 successful interventions were achieved, about half of what was normal before full installation, suggesting that the problem does not disappear suddenly. In fact, there are still people who come with the idea of ​​jumping, but now the margin of action is greater and death is no longer as immediate or as certain as it was for decades. Installation of anti-suicide barriers, February 2020 Against inertia and cost. The truth is that the installation of the barrier came after a very long road full of political blocks, doubts about aesthetics, discussions about price and debates about if it would really work. Already in 1939 it was recommended to raise the railings, but for decades measures were avoided while the death count rose from 500 to 1,000 and it continued to grow with chilling regularity. The organized pressure from family and professionals ended up crystallizing at the Bridge Rail Foundationand after years of paperwork the work started in 2018. The project also became very expensive, going from an estimate of 76 million dollars to a final cost of 224 million dollarsand even took longer to install than the bridge itself to build. The “invisible” barrier Why it saves lives. One of the central ideas is that reducing easy access to a lethal method works, even if it sounds too simple. A 1978 study by Richard Seiden, at the University of California at Berkeley, followed 515 people who had gone to the Golden Gate with the intention of jumping and were deterred, and concluded that 94% were still alive or had died of natural causes. This reinforces the idea that many suicidal crises are acute and not permanent, and that placing a specific obstacle at the exact moment can make the difference between dying and surviving. Bridges and the same problem. There is no doubt, the Golden Gate incident was not an isolated case, and there are other iconic bridges that have ended up with a similar reputation by becoming recurring scenes of suicides. In the United States, the royal gorge bridge next to Hoover Dam, or the Chesapeake Bay Bridgethey have had known histories and episodes that have fueled debates about surveillance and barriers. In Canada, the Bloor Viaduct in Toronto was for years one of the most problematic points until it was installed a great prevention structureand something similar happened in the United Kingdom with the Clifton Suspension Bridge in Bristol, where the combination of height, accessibility and symbolism forced action and reinforce early intervention. Also in Australia, the Sydney Harbor Bridge has been targeted of concern and initiatives preventive, and in Europe there are numerous cases on urban bridges and high-rise viaducts that share the same pattern: very busy and at the same time very exposed. The same idea is repeated in all of them, when a bridge becomes a known point, it is not just a problem of physical security, it is a social phenomenon that feeds on itself, and the more famous it is, the more important it becomes to cut that inertia before it becomes part of your identity. The legacy. The Golden Gate had been in operation for decades … Read more

A hero without a cape recorded the same shot for a year. Along the way he left the flat earthers without arguments

by

Intrigued by the phenomenon, Eratosthenes decided make an observation in Alexandria, located about 800 kilometers north of Siena. There, on the same day and at the same time, he noticed that a vertical stick did cast a definite shadow. The discrepancy led him to a fundamental question: how was it possible that in one place there was no shadow and in another there was, at the same time? Eratosthenes deduced that the only explanation was that the earth’s surface was curved. A lot of time has passed since then, but the flat earthers are still among us. The home experiment. For centuries, the idea of ​​a flat Earth has outlived telescopes, satellites and lunar missions. Despite the overwhelming evidence, from the images taken from space and the established physical principles from Aristotleflat earthers have continued searching for the edge of the planet, organizing expeditions to Antarctica or navigations to the supposed “end of the world” that invariably end with the same discovery: that the edge does not exist. Be that as it may, an anonymous Reddit user has dismantled once again his entire creed without leaving home. Armed only with a security camera, the shadow of his garage and the patience of an entire year, he managed to record a test as simple as it was incontestable: the movement of the Sun drawing a figure of eight perfect on the ground. The footprint of the Sun. Between March 2024 and March 2025, this user (under the alias RedditorofReddit07) marked daily, at the same time, the position of the end of a shadow cast by a corner of his garage. After twelve months, the yellow dots traced on the cement an asymmetric curve in the form of infinity: an analemma. This phenomenon, documented by astronomers for centuriesis the direct result of the 23.5 degree tilt of the Earth’s axis and the planet’s elliptical orbit around the sun. In the summer months, the star reaches the highest point of the analemma; in winter, the lowest; and during the intermediate seasons the rest of the figure is drawn. Each latitude generates a slightly different shape, but they all share the same essence: an Earth that moves, rotates and tilts, not a motionless disk under a celestial lantern. The physics of time. The analemma not only reveals the movement of the planet, but also the difference between solar time and time measured by clocks. In theory, noon always occurs at 12 o’clock, but the Sun does not reach its highest point at exactly the same time every day. This variation, a consequence of the inclined axis and the unequal speed with which the Earth travels its orbit, is the reason why the analemma adopts a figure-eight shape. Science sums it up in a formula called the “Equation of Time,” an adjustment that explains why solar days vary in length and why the apparent position of the Sun advances or lags throughout the year. This mismatch is as predictable as it is beautiful, and can only be explained by a spherical planet that orbit a starnot by a flat disk with a wandering Sun that rises and falls without altering its size. The impossible refutation. In the flat earth modelsthe Sun moves on a plane, like a lamp on a table, projecting its light in circles on the surface. If that were true, the end of a shadow always observed at the same time should remain fixed throughout the year. However, the garage experiment shows exactly the opposite: a harmonic displacement that only fits the heliocentric model. Reproducing this effect in a flat world would require, in addition to an act of faith without a network, that the Sun change its trajectory, height and speed in an absurd way, violating the very laws of optics and gravity that its alternative model allows. The flat earthers themselves, faced with such evidence, barely manage to develop new explanations that are more imaginative than scientific. The method. He merit of the experiment It lies not in its complexity, but rather in its humility. Without telescopes or laboratories, a simple fixed camera and a daily routine were enough to record the annual dance of the Earth in front of the Sun. Each shadow point marked on the cement is a slap to the conspiratorial noise that floods the internet. In times when science is forced to defend the obvious, an ordinary garage has become an observatory and an anonymous user a popularizer. He already said it Carl Sagan himselfalthough he only needed a stick to dismantle conspiracies. Image | reddit, jailbird In Xataka | 48 people went to Antarctica to prove that the Earth is flat.

Thousands of people recorded a B-52 at a fair. Shortly after, a commercial flight had to maneuver sharply to avoid it

by

Skywest flight passengers, operated as Delta Connection between Minneapolis and Minot (North Dakota), starred in an unprecedented incident on Friday. The captain of Embraer 175 turned sharply The plane during the approximation by distinguishing a B -52 bomber from the American Air Force too close to its trajectory, which caused surprise and alarm on board. In a video recorded by the passenger Monica Green and Posted on Instagramthe pilot excuses the passengers: “Given their speed – they were military, I don’t know at what speed they were going, but they were much faster than us – I thought it was sure to turn around. They greatly apologize for the aggressive maneuver. It took me by surprise. This is not normal.” An unexpected event that is being investigated The FAA opened an investigation into the event on Monday. Skywest clarified thatdespite having permission to land, the flight made a frustrated approach maneuver By sighting another aircraft in its trajectory. The company is also evaluating the incident from its side. If you wonder what a B -52 was doing in that area, I was fulfilling a scheduled overflow for the North Dakota State Fair, As confirmed by the Air Force. That event is held in Minot, where a civil airport and an air base coexist. The military statement specifies that “The tower did not report the commercial plane”And, after exceeding the fairgrounds, he was ordered at the bomber to move three kilometers west. Tiktok @Theruralrose user recorded the two aircraft in the air from the North Dakota State Fair Platform monitoring data Flightradar24 reveal that he Embraer 175 He made an abrupt turn to the right, recovered altitude and remained waiting before restarting the approach. FAA added that air traffic control in Minot is managed by an external companywhose operators have “the same training and qualification requirements as those of FAA.” Green told CNN: “It was a very right turn and then he went quite to the sides. I looked out the window and all I saw was the grass.” The Embraer 175 belongs to the E -Jet family, a range of regional aircraft manufactured by the Brazilian Embraer. It is a narrow fuselage design thought for short and medium radio routes. Normally it transports between 76 and 88 passengers according to single or double class configurations, with turbofan engines GE CF34-8E and a vCruise elocity near 890 km/h (Mach 0.82). Its typical reach exceeds 3,300 km.

There is already a detainee for using the Meta Ray-Ban to record without consent. Recorded hundreds of women in Barcelona without finding out

by

A young man has been arrested in Barcelona After recording hundreds of women with smart glasses without their knowledge. What he did with those recordings: use them in their “seduction” courses that sold for 3,000 euros. Why is it important. It is the first known case in Spain where Ray-Ban Meta They are used to commit crimes against intimacy. The victims did not know that a camera that they did not detect recorded conversations about personal information that later disseminated and monetized. The facts. The detainee approached foreign tourists in Barcelona, ​​held apparently casual conversations and recorded them with glasses that had an integrated camera. Without noticing it, and in fact hiding it. The videos were later published in Tiktok and Instagram as a claim for their “seduction techniques” courses. In figures: 329 videos analyzed by the police. 239 Conversations with intimate data of women. 700,000 visualizations reached the video of the complainant. 3,000 euros cost the full course (plus 45 euros per month of subscription) The technical problem. The Ray-Ban Meta (329 euros) emit a white light when recording, but it is easy to hide them with small tricks. The majority of victims did not detect being recorded, according to police investigation. Smart glasses pose a privacy dilemma that we had not had to face so far, although it already anticipated a decade ago with The Google Glass opening the way. Ray-Ban Meta are much more concealed. Let’s not talk compared to a mobile. Yes, but. Goal designed a safeguard: the indicator light. The problem arises when malicious users deliberately avoid them to record without consent and then make malicious use, or at least to monetize or spread them. Goal is preparing more AI functions for these glasses that will identify places or people in real time. Some users have achieved it on their own. This arrest promises to be the first of many conflicts that are yet to come between body technology and privacy.

We have been asking who is the oldest person in history to be recorded on video for years. And maybe it’s a Pope

by

The history of art is the history of its protagonists. And that includes both its great creators, so let’s talk about painting, sculpture, poetry or music, as well as their patron, muses and models. Da Vinci It has been fascinating for years to historians, but it is difficult to address their biography without explaining at least past who was Lisa Gherardinithe woman who probably inspired the celebrated ‘Mona Lisa’. The same goes for the enigmatic Elisa to which Ludwig Van Beethoven dedicated her catchy Bagatela Woo 59 either Margherita LutiRafel’s great muse. With photography and cinema something similar happens. And although their origins are more recent than those of painting, music or sculpture, historians who take care of their study face questions equally complex and fascinating: who was The first person to go out in a photo? And the oldest? Who is it The oldest voice captured in a support that allows us to reproduce it? And if we talk about cinema, Who is the oldest person filmed? Did technology and art arrive in time to capture in a recording the gestures and movements of someone born in the eighteenth century, which saw the French revolution wave War of Independence from the US? And if so, can we see it? The “vestustos” of the image and sound The question is fascinating because photography has allowed us to see static images of people born in the 18th. This is the case of Conrad Heyera veteran of the US War of Independence that was born in 1749. He was portrayed in 1852, with more than 100 years, thanks to the technique of daguerreotype, so There are those who believe which is the most ancient person (not the first photo, eye) photographed. The title nevertheless has some “but” than another. Heyer’s image is fascinating, but Other experts think that if we talk about vetustez the merit of being the oldest person portrayed with a camera is John Adamsa worker of Worcester born a few years before Heyer, in 1745. Other sources speak of a slave named Caesar, protagonist of a 1851 daguerreotype conserved in New York Historical Society and who in theory was born in New York in 1737. If what we are talking about is about the voice, the story is equally fascinating. We keep A recording 10 seconds from 1860 Taken with a spell and that is attributed to Édouard-Léon Scott by Martinvillea French inventor born in the Paris of 1817. Again if what we are talking about is of antiquity, perhaps The most ancient voice that we keep engraved is nevertheless Helmulth von Moltkea Prussian marshal who lent several recordings at the end of the 1880s. The surprising thing is when Moltke was born: in 1800. And at the dawn of the cinema? Who is the oldest person than we keep a moving recording? The answer is complicated again, although equally surprising. At the end of the 1870s EADWEARD VERYBRIDGE elaborated in A protopeic in which you can see the gallop of a horse with your rider. Your identity? Some sources They point to C. Marvinborn In 1839. If it scratches in the origins of the celluloid it is, however, to meet even older “actors”. And also some other surprise. For example, It is usual that when talking about the oldest person ever filmed, the looks are directed to one of the great personalities of the nineteenth century, the Pope Leo XIIIwho also holds the merit of having been The first Pope filmed. The movie, by William Kennedy Dickson For the Biograph company, was shot in 1898 (there is who attributes it to Vittorio Calcina and the date in 1896) and although it is fascinating and iconic, any Oscar will hardly win. After all, he shows the Supreme Pontiff in more or less everyday situations: on a car or sitting in a chair in the Vatican gardens while making a blessing in the camera. The really surprising is not however What does Leo XIII doif it is the first pontiff recorded in a movie or who, when and where he took those images for history, but the year of birth of the Pope: Leo XIII He was born in the Lacio region with the name of Gioacchino Vincenzo Raffaele Luigi Pecci in March 1810. That is, for ten years he was not a character of the XVIII. Does that become the oldest person ever filmed? Depends. For some The answer is yes. For others that merit is not so clear. In the articles that address the subject, there is talk of a Rebecca Clark allegedly born in 1804 or Mammy Louof the same year. However, there would be an older candidate, a figure that once aroused much less interest than Leo XIII and to which, therefore, it is also more difficult to follow the historical clue: dismiss. That your name does not tell you anything is understandable. Despina was an old woman from the Balkans who among other tasks dedicated the hours to spinning wool in the company of her daughters. In 1905 it ended up portrayed in A brief movie that lasts a few seconds. The important thing is its date of birth: it is said that Despina was then 114, which would have been born at the end of the 18th century, In 1791. How did an old woman from Avdella end, then part of the Ottoman Empire, recorded spinning wool for the subsequent and turned into a key figure in the history of cinema? Simple: because it was the grandmother of Ianachia and Milton ManakiBalkan cinema pioneers and film authors ‘The weavers’. We already said it at the beginning: the history of art is the history of its creators … and of their circumstantial protagonistsamong which there are farmers, war veterans, shoemakers, centennial spinners and even a 19th -century Pope.

The first time a ship recorded an eclipse from the moon was in 1967. The second has been today

by

The blood moon is a land of blood from the lunar surface. The early morning of March 14, the Lunar Blue Ghost landizer of Firefly Aerospace He registered a solar eclipse from his unique perspective on the moon. It is the first commercial ship that achieves it. And the second in general, from the NASA Surveyor 3 probe in April 1967. Eclipse lunar, solar eclipse. In a lunar eclipse, the earth stands between the sun and the moon, projecting its shadow on the satellite, which acquires a reddish tone due to the longest wavelengths that are filtered through the atmosphere. Hence it is known as “blood moon.” From the point of view of the moon (the visible face of the moon, to be exact) is a solar eclipse. NASA’s Surveyor Lunar 3 probe was the first in register how the earth is blocking the sun to form a diamond ring, similar to the one we see from here during the total solar eclipses. The first private mission to record it. In addition to Surveyor, Apollo Missions Astronaut The Kaguya Japanese probe in 2009 They have been able to register them from the lunar orbit. But Blue Ghost has been the second ship to document a total solar eclipse from the satellite surface. Similarly, Firefly Aerospace has become the first private company to get this milestone. Not surprisingly, it is the first to have achieved a gentle in vertical, something they have tried Several companies in recent years with little success. Everything got red. The eclipse It started at 5:30 UTC on Friday. At 8:30 UTC, the ground around the ship and the surfaces of the ship itself They had acquired an intense reddish tone. At 9:30 UTC, the Blue Ghost lunar module photographed Your first diamond ring: The silhouette of the earth framed by the brightness of the sun, with a flash crowning it as a piece of goldsmiths. Firefly has been clearly victorious in one week in which another Texas company, Intuitive Machines, has tried to alunize its Nova-C ship. The landing “Athena” fell sideways and could not recharge his batteries, dying within a few hours. Blue Ghost, on the other hand, landed at first and deployed a heat probeamong other NASA experiments.
