China just launched a rocket without telling anyone. It turns out that it is the most ambitious in its history

by

China has taken seriously that “first come, first served” thing. Although the 1967 Outer Space Treaty states that No State can claim sovereignty over the Moon, Mars or any other celestial body, what does apply is that the geostationary orbital positions and frequency bands work as “first come, first served”. What does this mean? Well, the country or company that first registers and coordinates a constellation or a position with certain frequencies gets priority of use. This context is necessary to understand why SpaceX or Amazon are so interested in mass launching satellites into low orbit, and also why China has been accelerating the pace for months with their rockets in an aggressive expansion maneuver. So aggressive that finish of surprise and secret launch of a Long March 12B rocket with a double objective: to continue feeding its satellite constellation and to demonstrate that its reusable rocket can compete against the Falcon 9 from SpaceX. China and the space sprint This past Monday, the operators of the Jiuquan Satellite Launch Center, in the Gobi Desert, had work. In the American early morning, a rocket Long March 12B It left for low orbit with a cargo of satellites that will feed the Qianfan megaconstellation. This is China’s response to SpaceX Starlink and it seems that the mission went well because the China Aerospace Science and Technology Corporation declared the flight a success. There is a double reading here. On the one hand, the Long March 12B is one of the responses to SpaceX’s Falcon 9. It is a reusable rocket that has a first stage intended to land by propulsion on a recovery platform on Earth. It can transport 20 tons to low Earth orbit and this was its first flight… although was not done no recovery attempt. The other reading is that China is in aggressive mode launching things into space. It has been a very busy few months with different missions both in low orbit and in its Tiangong space stationbut the interesting thing about this launch of the Long March 12B is that people found out through social networks. When a mission is going to be carried out, whether it is more or less media-related, a series of prior notices are made to both the international authorities that control the air and maritime space in case something goes wrong. However, This mission has been carried out in absolute secrecybeing an unusual practice in both government and private programs. In the end, it is one more demonstration of what we were talking about: China has stepped on the accelerator to claim a space that can only be claimed by getting there and occupying it, and that is vital within the framework of user service (satellite Internet, wow) and, above all, for strategic reasons and technological sovereignty. Because it may seem that companies and countries want to bring the Internet everywhere, but the strategy is different: Controlling constellations and their orbital resources means controlling critical infrastructure such as satellite Internet, Earth observation, and military communications. Geopolitical advantage by arriving first in a space that the rival might want to occupy with other types of satellites. Arriving first forces the others to play on their board. And most importantly: the space you are interested in occupying is finite and everyone wants their land as soon as possible. In the end, this “secret” flight marks number 647 of the Long March series and is one more example that China is deeply involved in a new space race in which it competes directly against the United States, but in which Europe is also working to have something to say.

It turns out that birds and insects live much better under them

by

We have been hearing for years that the expansion of solar parks threatens the countryside. The mental image we usually have is of hectares and hectares of black panels under a relentless sun, devastating the landscape and without a single bird for miles around. However, the data is beginning to tell a radically different story. There is more life inside than outside. To understand this phenomenon, we only have to look at the most recent data in Spain. According to a report from the Spanish Photovoltaic Union (UNEF)endorsed by the independent environmental consultancy EMAT, photovoltaic enclosures are proving to be refuges full of life. After analyzing different facilities in 2025, the pattern is repeated within the park, there are more species than in the adjacent agricultural field. The numbers in three different provinces leave no room for doubt: Minglanilla (Cuenca): Researchers counted a total of 32 species of birds inside the solar plant, compared to the 19 they found in the control agricultural area located just outside. Revilla Vallejera (Burgos): The balance recorded 39 species inside the facility compared to 34 outside. Trujillo (Cáceres): 31 species were detected living between the panels, compared to 25 outside them. And what kind of tenants are arriving? They are not just common birds. The presence of protected or declining species such as the curlew, the little bustard, the roller, the owl and the lesser kestrel have been documented. And the food chain works its magic: as wild vegetation grows, insects arrive; with the insects, come the birds; and the abundance of these prey is attracting birds of prey such as eagles, vultures, hawks and owls. There is no technology, but something simpler. To understand why this is happening you have to change the reference point. The question is not whether a solar park is ecologically better than a virgin forest, because it clearly is not. The key is to compare it with what was before in that field. In the vast majority of cases, these fields were previously intensive agricultural operations: impoverished landscapes, treated with herbicides and profoundly silent. In contrast, installing a solar park de facto introduces an ecological exclusion zone. In other words, no pesticides or herbicides are used, hunting is prohibited and there is no tillage of the land, and human presence is reduced to very specific maintenance visits. As Martín Behar points outdirector of Studies and Environment at UNEF, this lack of chemicals, added to natural vegetation management through extensive grazing, is generating fantastic results on biodiversity. Spain It is not an anomaly. At an international level, what science is beginning to call “conservatory” systems (the union of renewable generation and active conservation) already has fascinating evidence. In the United Kingdom, a study led by the RSPB and the University of Cambridge analyzed six solar parks in East AngliaEdit. The conclusion was that they housed a greater wealth of birds than nearby crops. In those better managed (with unpruned hedges and varied vegetation), almost three times as many birds were found than in neighboring fields. But perhaps the most curious story comes from Australia. A Lightsource bp study followed 1,700 merino sheep for three years. Half lived in traditional grass fields and the other half lived among photovoltaic panels. The discovery surprised everyone: the sheep that grazed in the solar park produced better quality wool. The reason is that the microclimate under the modules allowed them to alternate between fresh forage, dry grass and hay several times a year, something not feasible in a normal paddock in full sun. It’s not enough to plant the panels and cross your fingers. Of course, the researchers themselves warn of something fundamental: that solar parks can benefit the ecosystem does not mean that they always do so by magic. It is not enough to install the panels and wait. If you just cut the grass close and leave a “simple habitat”, there will be no miracle. For the magic to happen, active management is needed: maintain vegetation covers, use native vegetation on the margins, create ecological corridors and rely on sheep as a natural lawnmower. To push the industry in this direction, UNEF has promoted a Seal of Excellence in Sustainability, developed hand in hand with experts from WWF and SEO/BirdLife. The debate is changing. What makes photovoltaic energy an ally for biodiversity or a territorial threat is, simply, what we decide to do with it.

They detect if you are wearing your seat belt, if you are on your cell phone or if you make illegal turns

by

Pamplona is going to significantly strengthen its traffic surveillance system starting next June. Although we recently knew the setup of the new section radar of the AP-68which by the way is the second longest in Spain with more than 30 km of distance covered, now the Pamplona City Council will launch four radars with AI capable of hunting down practically any driving violation, from carrying your cell phone in your hand to driving without a seat belt, jumping a red light or changing lanes improperly. Automation. Until now, these types of violations depended on traffic officers. The arrival of these radars automates this surveillance and, above all, it will work as a pilot test in the country, because if they end up giving good results, it is reasonable to think that we will see this technology spreading to other Spanish cities and roads in the coming months. What do they detect?. The new devices incorporate a color camera and a license plate reading system that, combined with AI technology, identify a whole range of illegalities while driving. According to the City Council, they will be able to detect: Use of mobile phone while driving. Drivers without seat belts. Traffic in the opposite direction and prohibited turns. Improper lane changes. Running a red light. Do not respect zebra crossings or stop in yellow-marked areas. Added to all this is a speed control system, with a range that goes from 10 to 320 km/h. The objective according to the City Council is to “monitor compliance with traffic rules, regulate speed and avoid accidents in the city”, as share from Navarra News. What are they like?. The gray cabins are something that has been left behind on these new radars. These are mounted high on staffs, medians or gantries, and withstand temperatures between -30 and 70 degrees without the need for a protective casing. Another important novelty is that they cover several lanes at the same time and bidirectionally (both approaching and receding vehicles) and allow different speed limits to be configured for each lane. Where will they be installed?. Although the idea is that rotate between the eleven cabins that are spread throughout the city, the first planned locations are Army Avenue, Gipuzkoa Avenue next to the Oblatas Bridge, Sadar Street and Paseo de Santa Lucía. The fact that they rotate is precisely designed so that the driver never knows for sure if the cabin in front of him is working or not. Between the lines. Each radar It has cost the City Council 20,000 euros (VAT apart), an investment that the City Council considers justified by the number of infractions that a single device is capable of detecting. In addition, it should be taken into account that a device of this type can fine for behaviors that previously required the presence of an agent or were easier to avoid. So it is quite likely that they will end up recovering the investment based on fines in a short time. Before starting to operate, the radars must pass the approval process of the Spanish Metrology Center, a step that the City Council hopes to resolve in time to activate them during June.

It turns out that at least half of what orbits the Earth is garbage. And that’s only what we can see

by

Around the Earth is the moon and a lot of space junk. And it is not an exaggeration: we have decades launching satellites into space without a clear or unified strategy. Of those waters, these muds: only Starlink has 9,000 units orbiting and has requested permission to launch a million more. What began with a technological race between superpowers has become an orbiting dump that has serious implications: threat of catastrophic collisions (every time we launch something, we buy another ticket in this macabre lottery) to risk critical infrastructures such as GPS navigation or communications. But all this is not new: science has been warning about it for years. The truly disturbing thing is not so much that the problem has been diagnosed, but rather that there is no simple solution. Space debris will not degrade with rain nor will it be decomposed by microorganisms. What goes up, stays there. And everything that remains is a real threat to what is there that truly matters. Almost half of what is in orbit is garbage. The engineering company Accu has used public data of the United States Space Corps through the web Space-Track.org and has analyzed them: there are 33,269 trackable objects in orbit, of which 17,682 are satellites. What happens to that other 47%? What is space debris: abandoned rockets, dead satellites and thousands of fragments resulting from collisions, among other unidentified objects. Stay with this information, because it is important and we will return later. Why is it important. From high school physics: we have already seen that there are objects of all types and sizes, but the majority of them they travel At more than 27,000 km/h and that speed, even the smallest piece can be lethal. To put it in context: a one-kilogram fragment impacting at 10 km/s has a kinetic energy of 50 MJ, that is, its equivalence in TNT There are 12 kg of explosive, enough to completely destroy an entire satellite of several tons. Losing a satellite is not the worst thing that could happen (even if its function was critical), but the Kessler syndromean irreversible chain reaction: if two objects collide and generate thousands of fragments, these fragments can collide with each other, generating more and more until making the orbit unusable. Context. It all started with the launch of Sputnik 1 in 1957, but the problem has gotten out of hand in the last decade due to something that a priori was good: the cost of launches has plummeted, so there are more and more and in fact, there are even commercial constellations, like Starlink. Only between 2020 and 2025 the number of trackable objects in orbit grew by around 10,000 units. You can see the history of all objects launched into space in Space-Track.org. Maybe after hearing so much that the wolf is coming we downplay it, but it is already happening: in 2024 the astronauts of the International Space Station they had to take refuge after the fragmentation of a decommissioned Russian satellite. In 2025 Chinese astronauts they were trapped at Tiangong Station after a piece of trash cracked the window of their return capsule. The worst is what we don’t know. We mentioned before that 47% of space debris, but that is only what we can see: the European Space Agency calculate that there are more than 1.2 million fragments larger than one centimeter in orbit and that more than 50,000 exceed 10 centimeters, enough size to completely destroy an active satellite if both impact. The figure amounts to more than 100 million objects of one millimeter or less, according to NASA. Even a flake of paint. In addition, each space power manages its own tracking data with different levels of transparency, making it difficult to have a complete and reliable picture, a map of what is in orbit. The gap between what is trackable and what is real is abysmal: current surveillance systems can only reliably track objects larger than 10 centimeters in low orbit and larger than one meter in geostationary orbit. Everything that remains outside that threshold is simply invisible, not innocuous. As if that were not enough, there is one more dynamic variable to introduce into the equation: the interaction between debris and space weather. A 2025 study warned that an intense solar storm could cripple satellites’ ability to maneuver long enough to cause cascading collisions and that there would be less than three days to react. Whose fault is it. The origin of space debris is essentially concentrated in three blocks: China, the United States and the countries of the Commonwealth of Independent States, heirs of the Soviet space program, concentrate on their shoulders about 95% of all waste cataloged in orbit. With data from March 2026, China accounts for 34% of the total debris tracked, closely followed by the CIS (Russia and eight other small countries) with 31% and the United States with another 31%. The underlying problem is legal: the international treaty that regulates space dates back to the 1960s and does not prohibit destroying satellites with missiles. Nor has anyone been serious about minimizing the launches. Without a clear policy to reduce waste, verification mechanisms or real sanctions, little can be expected, such as documents the UN.

It turns out that there are invasive land snakes that take to the sea from Ibiza. And they are annihilating a unique lizard

by

In addition to being one of the great European tourist destinations, the Pitiusas Islands have a unique jewel of nature: the pitiusa lizarda unique reptile in the world that only lives there. By living in isolation, the lizard populations on each islet have evolved independently, giving rise to 28 different subspecies. This biological jewel today has a direct and truly terrifying threat: the horseshoe snake, a foreign species that was accidentally introduced to Ibiza in 2003, probably through ornamental olive trees imported from the Iberian Peninsula. Or so they thought: spotting a horseshoe snake is no longer something occasional, but they can even be seen swimming in the open sea. Spoiler: they are terrestrial snakes. what’s happening. The Center for Ecological Research and Forest Applications (CREAF) has published an academic article that covers the origin and invasion status of the horseshoe snake. The expansion map is conclusive: in 2010 the snake was present in less than 5% of the Ibizan territory, in 2016 it already occupied 40% of the island and in 2025 it had reached 90%. As stated by the research team led by Guillem Casbas and researcher Oriol Lapiedra, when it conquers a new area, it can take less than three years to eradicate the entire population of lizards. The speed of expansion is unprecedented among invasive snakes in Europe. What has never been seen is also the most disturbing: they have documented how snakes swim between islets, that is, they carry out active colonization. In 2024 they recorded a snake crossing 430 meters of open sea to the islet of Santa Eulària. The same sea that has served over the years as a barrier to the evolutionary isolation of the pitiusa lizard is no longer enough to protect it from its predator. The unstoppable advance of the horseshoe snake. Ecology Why is it important. The extinction of a species is always bad news from the point of view of fauna diversity, but this one is unique: its goodbye means that a unique and irrecoverable evolutionary lineage disappears, and according to the IUCN It is already cataloged as threatened, which means that population models predict a severe and continued reduction in the short and medium term. Beyond taxonomy, this eventual extinction would have its effect within an ecosystem as particular as the island and its balance, which could end with more extinctions due to a domino effect. In the case of the pitiusa lizard, it has pollinating and seed dispersal functions and if it does not do so, it puts the reproductive success of plants in check. On the other hand, and although its importance is more relative, the Pitiusas lizard is one of the great cultural and identity icons for those who are from Ibiza and Formentera: this amphibian is deeply rooted in the collective local imagination and popular mythology. Context. The magnitude of the problem is best understood within the biology of the islands. Islands are especially vulnerable ecosystems to invasive species because the loss of a single species can trigger cascading effects throughout the entire biological community. Invasive species enter the islands like an elephant enters a china shop: they compete for resources (more limited), alter habitats (smaller) and disturb ecological processes. The Pitiusas lizard is a critical node for the islands: however, was For millions of years it was the only terrestrial vertebrate in the archipelago and did not develop anti-predatory behaviors against snakes. A parallel case studied in depth is that of the brown tree snake on the island of Guamwhich decimated native bird and lizard populations, causing an increase in insects and altering forest dynamics. tragic consequences. The immediate ecological consequences are severe and quantifiable: there have already been local extinctions of lizards on at least 10 islets, and the snake has colonized between 12 and 15 of them through active swimming. And unfortunately, it’s just the beginning: this global study highlights that the impact of invasive vertebrate species on seed dispersal in island ecosystems is even greater than that caused by the extinctions of native fauna. Or what is the same, there may be a disruption in the plant regeneration of these islets. Likewise, its disappearance can take its toll on agriculture indirectly, as the lizard regulates the insect population. Is there a solution? The most urgent and important shock measure is to actively control the snake invasion. In 2025 the Balearic Government surpassed the 4,400 captures of invasive snakes in the Pitiusas and has already opted to leave the traps throughout the year. In 2026 the device will continue to expand with more resources. Of course, with a presence of 90% already in Ibiza, total eradication is unfeasible in the short term: the most realistic thing is to contain the advance and protect refuges. On the other hand, the conservation of the pitiusa lizard is also a priority objective, with several breeding lines of pitiusa lizards with genetic criteria in collaboration with the Barcelona Zoo. In the long term, the only structural solution is to combine the control of the snake with the conservation of the lizard’s genetics for a later reintroduction into its territory.

Starlink has been ruining astronomers’ nights for years. Now it turns out that their launches are leaving their mark on the climate

by

Much has been said about the great light pollution that generate the Starlink satellites from SpaceX. However, not so much has been said about something that, if we think about it, is much more evident. Air pollution derived from launches. Any space launch, in fact, can generate this type of contamination. However, satellite trains require such a large number of launches that it is not unusual for them to be of particular concern to scientists today. 15,000 satellites and counting. A team of British and American scientists has carried out Recently a study brought this problem to the fore and predicted what the effects could be in the short term. This investigation indicates that there are currently around 15,000 telecommunications satellites in orbit, more than 10,000 of which belong to SpaceX. This represents three times as many satellites as in 2020 and the worst thing is that the number continues to increase. As a consequence, according to the simulations of these researchers, by 2029, these satellites could account for 40% of the atmospheric pollution derived from space activity. Also have calculated that by then this sector will be releasing around 870 tons of soot into the atmosphere annually. It would be more or less the same amount released by all cars in the United Kingdom, so action must be taken as soon as possible. Launch and reentry problems. The two key points at which these trains of satellites will put our planet’s climate on the ropes are launch and re-entry. With the first, a large amount of black carbon. These are fine carbon particles that come from the incomplete combustion of fossil fuels. Regarding reentry, it mainly releases aluminum oxides. The satellites must be changed every 5 years. Later, when orbital conditions are favorable, this re-entry can occur, the price for which for the planet is also very expensive. The effects. Black carbon is harmful to the Earth’s climate on two levels. On the one hand, the particles that make it up have a great capacity to retain the heat of the Sun. That is why they play a very important role in the global warming of our planet. On the other hand, they can affect cloud formation in two different ways. Sometimes they prevent their formation, causing droughts, and other times they trigger extreme rainfall. Regarding aluminum oxides, can damage the ozone layerwith all the harmful effects that this entails. The place matters. The main problem with the release of these polluting substances is that it occurs in the highest layers of the atmosphere. The contamination at this height, if space activity did not exist, would be residual. However, the launches deposit that black carbon there, which remains for 2 to 3 years, retaining heat and affecting the clouds. That is why black carbon derived from space activity is estimated to have a much greater effect on the climate than that of ships, cars or power plants, for example. What is to come is very dangerous. It is said that Elon Musk wants to launch a million satellites into space. This is possibly an exaggerated figure. But it is clear that SpaceX has enormous objectives set. In fact, already It is even looking for launch platforms outside the United Statesbecause in his native country there is no room for such ambition. To all this we must add that other companies have increasingly ambitious objectives with their own satellite trains. This is, for example, the case of Amazon with Leo. The situation can become very worrying if alternatives are not sought, such as less polluting fuels for launches or more durable satellites that require fewer re-entries. Science will probably take us there at some point; but, in the meantime, the consequences for the planet will become worse and worse. We have time to solve it, but we must act now.

I always thought that a Stream Deck was only for streamers. It turns out to be a gadget that saves you a lot of time every day

by

It is not easy to work in front of a computer for many hours a day (whether at home or in the office). You spend the entire day browsing between documents, spreadsheets, files or writing emails and, just moving from one task to another, you already waste a lot of time. I really like the concept of ‘optimize workflow‘so that this does not happen (or happens little), but it is not easy at all. There are many ways to try to do this, although few are as visual as using a Stream Deck. Yes, that little device that many streamers have on their table and that seems to only serve to change scenes or cameras, but nothing could be further from the truth. It is a device that helps improve productivity in many waysand although there are a lot of models, my favorite is this Stream Deck Neo: right now it costs 84.99 euros. Elgato Stream Deck Neo – 8 customizable keys, 2 Touch Points, fly through your tasks and processes – Control Word, Excel, PowerPoint, Teams, Zoom, Spotify, etc. Easy setup – For Mac and PC The price could vary. We earn commission from these links Integrates with almost any software you use on a daily basis The idea of ​​the Stream Deck (of this specific model or any of the others that Elgato has) is the same: to have a panel that, with just the press of a button, simplifies tasks of all kinds. Let’s start with something simple: you can place buttons on a key to open the apps that you use most when working, such as an email manager, the browser or a Slack-type program. Or directly program a single button to open everything at once when you sit in front of the PC. In addition, it is a device that is very easy to install (it is basically plug and play) and configure. The software is also intuitive and allows us to customize the keys to the millimeter. Being compatible with software of all types, we can assign very specific keys to Photoshop, Excel or PowerPoint tools, for example. All, furthermore, with a very high degree of customization. I like this particular model for two things. The first of them is that it is compact and not as big as other models that Elgato has (which have more keys or even other types of buttons). The other is that it has two small touch panels that allow us to switch between the different “pages” of actions that we have configured. All of this means that we have a tool that will help us (a lot) to give a boost to our ‘workflow’. You also have other different Stream Deck models As I said above, there are different models of this gadget. In fact, this same year it released a keyboard in collaboration with Corsair that, directly, integrates a Stream Deck where the numeric keypad usually goes.

We believed that the success of artificial insemination was a genetic lottery. Turns out it depended on your shopping list.

by

When we consider having a child, the truth is that there are many factors that can intervene such as real obstaclessuch as age. This means that science is focused on looking for different variables that can be ‘altered’ to tip the balance in our favor and favor fertility. And the last one that has been known is related to the much loved Mediterranean diet. A new investigation. In a recent published study in the magazine Food & Function, A Spanish research team has come to the conclusion that it is not about eating healthily, but rather that we need a set of nutrients that the Mediterranean diet gives us, which directly modulate the ecosystem of bacteria that our body has and that prepares it for a successful pregnancy. The bacteria. On many occasions we see them as our enemies by causing very severe infections, but the reality is that they play a fundamental role within our body. In this sense, we have spoken on many occasions of the intestinal microbiota, but there are also large bacterial colonies in the vagina that protect against a large number of infectious diseases. In this sense, the research team analyzed vaginal samples from 104 women between 18 and 38 years old who had been diagnosed with primary infertility and were undergoing artificial insemination processes. What they saw here is that the success of fertility treatment depended largely on who “governed” the patients’ vaginal microbiota. The results. After crossing the samples with the patients’ diet, it was seen that those who followed a Mediterranean diet had a microbiome dominated by bacteria of the genus Lactobacillus. These microorganisms act as a protective shield and are strongly associated with a higher rate of successful pregnancies. On the contrary, a poor diet left the door open to bacteria such as Gardnerella vaginalis. This pathogen is not only linked to the annoying bacterial vaginosisbut the study directly relates it to implantation failures and failure of artificial insemination. Because? Here the Mediterranean diet stands out for the micronutrients that foods contain and that we ingest almost without realizing it when we follow this dietary pattern that is so common in our country. Here vitamins A, C, D and E, along with beta-carotene, calcium and zinc, act as protectors of the vaginal ecosystem. These elements not only nourish the patient, but selectively nourish the Lactobacillus, strengthening defenses against bacterial vaginosis and creating the perfect uterine and vaginal environment for insemination to thrive. It is becoming more and more important. Although this study details for the first time this interaction between diet, vaginal bacteria and artificial insemination, scientific literature has already been warning that the refrigerator matters a lot in fertility. But previous studies already indicated that women who followed a Mediterranean diet in the months before undergoing in vitro fertilization had success rates that were up to 68% higher. In this way, you can see that it is increasingly important to keep in mind that what you are going to eat is essential for even a new life to take shape.

the spectacular technology that finally turns fencing into a spectacle

by

The tip of a foil in a professional fencing competition moves faster than the human eye can follow, and that limitation has condemned the sport to a secondary role in broadcasts for decades. A Japanese studio has been working since 2012 on an answer that combines 4K cameras, deep learning and augmented reality. This April 25, it debuts in its first professional competition, in Los Angeles. It’s difficult to follow. Fencing has rules like right of way in foil and saber, used to determine who wins the point when both fencers touch the opponent’s body at the same time, forcing the spectator to follow movements of the weapon in fractions of a second. According to the Rhizomatiks official technical documentationthe tip of the weapon takes up just a few pixels even captured in 4K, and the blade deforms so much when flexing that classic image processing methods cannot follow it clearly. How it works. This visualization system is called Fencing Visualized and is born from an alliance between the Japanese studio Rhizomatiksdirected by Daito Manabe (known for collaborations with Björk, Perfume and the closing ceremony of Rio 2016), the agency Dentsu Lab Tokyo and the fencer Yuki Ota, the first Japanese Olympic medalist in the discipline. The idea germinated from previous work with dancers in which the team used motion capture and high-speed cameras to draw graphics on the bodies on stage. The official phase began in 2013 and the concept already appeared in Tokyo’s bid video for the 2020 Games. Early versions of the system depended on retroreflective markers attached to the weapon: In 2014 it was tested live during the Yuki Ota Cup and in 2017 the balls were replaced with reflective tapes so as not to hinder the shooter. From reflective markers to deep learning. The technical leap has come now, when the team has worked to introduce the system in official competitions without interfering with the athletes’ competition equipment, mainly weapons. Therefore, in 2016 they rewrote motion detection with the help of deep learning. According to the engineer Kye Shimizuthe solution is a multistage network based on YOLO v3, fed by 24 4K cameras on both sides of the track, and whose results are crossed to estimate the position of the tip. This new version without physical markers debuted as an exhibition at the 71st Japan National Championships in 2018 and was seen in official competition a year later. The next milestone was Tokyo 2020, where the technology was deployed on site during the Games. That time at the Olympic Games is, in fact, what has allowed it to be sold to other competitions. Money. The American premiere on April 25 responds to a commercial logic adopted by the World Fencing League (WFL) that organizes the event, a professional league founded at the end of 2025 by three-time Olympian Miles Chamley-Watson. The competition brings together twelve athletes in mixed teams with a total distribution of $100,000 in prizes. The WFL itself describes the installation as a system of blade tracking with AI intended to make new viewers understand the action instantly. In other words: the league is interested in ensuring that, as a television show for all audiences, each round is understood intuitively, without knowing the regulations. More visions of the future. Fencing Visualized It is not an isolated case: There are systems like Hawk-Eye in tennis and cricket, Second Spectrum as the official optical tracking provider for the NBA and Premier League, or semi-automated offside in football. But the tiny tip of a saber is a more demanding problem than tracking a ball. On the other hand, this vision of the future also fits into the trend that the IOC has been promoting for years with Alibaba Cloud and Intel, and which turned Paris 2024 into the first end-to-end 8K broadcast with multi-camera 3D replay. The Los Angeles 2028 Games are a good space for this system to be integrated into the audiovisual dissemination of this sport.

It turns out that they have a loving arm that tastes the sex of females

Few animals are as fascinating as octopuses. These very intelligent invertebrates (since I saw “What the pulse taught me“I have a hard time consuming it) They have a brain in each armthree hearts, blue blood and a nervous system distributed by its tentacles. However, one of its greatest mysteries was truly intimate: how does a male manage, in the absolute darkness of a sea crevice, to locate the female’s reproductive system with surgical precision. Until now, science thought it was pure tactile instinct, but no: a recent study from Harvard University published in Science and led by Pablo Villar has discovered that the octopus does not look, it tastes love with the tips of its fingers. fingers suction cups. The love scene. Octopus mating is a sophisticated maneuver of extreme delicacy. The protagonist is the hectocotylthe third arm of the male: this tentacle is not used for eating or exploring, but for loving (in the most reproductive sense of the word). The maneuver is as follows: the male introduces this arm under the female’s mantle and there navigates between vital organs until he finds the oviduct, an opening of just a couple of millimeters. Once located, both remain motionless for approximately one hour, the time necessary for the transfer of sperm packets that the female will store throughout her life in a specific gland. Fingers that smell and taste. What the study shows is that the octopus does not “see” the path, but rather “feels” it on a chemical level. If it sounds strange, it is because humans actually lack that sensory modality, contact chemoreception. Going a little more into detail: the female emits progesterone, which will be the chemical lighthouse for the male in this internal navigation. He sensor of the hectocotyl is in its suction cups, covered by an epithelium similar to our retina or tongue, rich in receptors CRT1. According to the experiment, the male’s love arm is indifferent to other hormones: only when its CRT1 detects progesterone is the search and coupling response activated. It is literally tasting your goal with your fingertips. Why is it important. Beyond the obvious biological curiosity, this discovery has critical implications such as helping to understand how species separate and how biodiversity arises, as these receptors act as a sensory barrier: if the male’s receptor does not match the female’s chemistry, there is no copulation. On the other hand, they also put on the table the seriousness of endocrine disruptors as environmental contaminants, substances that act by imitating hormones that can confuse the male octopus and cause it to get lost. Finally, it is valuable information for aquaculture: octopus farming is a global challenge due to its complex reproduction and this finding is a step forward to optimize its sustainable breeding. From hunter to lover. One of the most fascinating aspects of this paper is how this ability originated: the octopus did not invent this loving arm out of thin air, but rather it is a recycling of an old tool for a new use. And originally the CRT1 receptors were used to detect molecules from their prey during hunting, but over time these receptors mutated with a kind of “hydrophobic pocket” that made it possible to develop that special sensitivity towards progesterone. An evolution from a survival sensor to one of genetic continuity. In Xataka | We knew that octopuses were very intelligent. But not to the point of having a “brain” in each arm In Xataka | England is experiencing an unprecedented invasion. The problem is that they are octopuses, and they are devouring everything they can find. Cover | Dear Sunflower
