Astronomers’ trick to hunt hundreds of nearby exoplanets: look for suspiciously “quiet” stars

by

The hunt for exoplanets in the universe has always depended on our ability to observe the invisible. Until now we have mainly noticed the flickering of a star when it passes in front of one of these planets or the subtle gravitational wobble that it causes, but we have never seen them directly. Now a team of astronomers has perfected a much more ingenious method: searching for planets based on the “false” magnetic tranquility of their stars. And now it works. The project known as Dispersed Matter Planet Project (DMPP) has just confirm the discovery of seven new planets spread across five star systems, and its projections indicate that there could be hundreds of rocky worlds hidden in our closest cosmic neighborhood. And we have not been able to ‘see’ all of these with our traditional systems. How it works. The DMPP method is fascinating because it turns the traditional way of observing the universe on its head. Now, instead of looking for active stars, the team selects bright, very nearby stars that have anomalously low calcium emission. In fact, they show levels of magnetic activity below their basal level. But these samples do not indicate that the star is without activity, but rather that it is hidden. Here astronomers have discovered that these systems host planets very close to the star, which due to the intense heat are evaporating. From this gas that is released from these worlds, a kind of ‘shield’ or orbital cloud is formed that absorbs radiation and hides the activity of the stellar chromosphere. That is, the star’s apparent inactivity is the gas “fingerprint” of a disintegrating planet. Its precision. To confirm these suspicions, the team does not stop at observing the gas, since it uses very high precision radial velocity spectrographs such as HARPS-Nwhich are capable of measuring minute variations in the star’s motion. One of the most intriguing case studies of the project is the system DMPP-4located about 25 parsecs away. In this star, candidates for planets with sub-Neptunian masses have already been detected, on the order of between 8 and 12.2 times the mass of the Earth, orbiting at breakneck speeds, with “years” that last only between 2 and 5 days. Where are they? These planets inhabit what astronomers know as the “Neptunian Desert,” a region very close to the star where planets the size of Neptune are rarely found. The leading theory is that these worlds are actually rocky cores of ancient Neptunes that migrated into the system and whose atmospheres were swept away by intense stellar radiation. Many to discover. The implications of this study are massive for modern astrophysics, as data from the DMPP project suggests that between 10% and 20% of these low magnetic activity stars could host compact systems of rocky planets that we have not known about until now. This not only helps explain certain anomalies in the historical catalogs of the Kepler telescope, but gives us a treasure map. As they are star systems so bright and close to Earth, these newly discovered exoplanets become the perfect candidates to be observed by the James Webb Space Telescope (JWST) and the future generation of Extremely Large Telescopes (ELT).

China has a nuclear reactor 100 times more efficient than traditional ones. The trick is to shoot atoms with an accelerator

by

China has had one goal in mind for some years: to have a voice in the nuclear race. In the weaponsyes, but also in energy. As Europe argues and the United States attempts to rejuvenate its critical infrastructure to meet AI needs, China has been on the accelerator for months. Recently they have not only approved 10 new reactorsbut they are one step away from turning on a new generation nuclear power plant to provide ‘green’ energy for 1,000 years. This is the CiADS system, or Throttle Actuated System. It is a type of reactor that China has been developing for more than 15 years and that promises to convert waste into energy. Their trick is to convert “garbage” into fuel, and it is a very interesting twist for nuclear energy. And even more so in a China that wants to dominate the atom and renewables as a basis for the development of another of the great ambitions of the country. Artificial intelligence. A twist to nuclear energy In a releasethe Institute of Modern Physics of the Chinese Academy of Sciences gave some details of how this accelerator-driven nuclear reactor works. Uranium is still the fuel, but “reactor driven by an accelerator” is literal. Using a particle accelerator, protons are “shot” at a heavy metal target at a speed of 0.8 times that of light. This generates neutrons that drive a reactor that operates somewhat below the critical threshold to be self-sustaining. The reactor generates energy and this violent reaction causes the long-lived radioactive isotopes that are normally generated in a conventional nuclear power plant to transmute and become materials with a shorter life. As its managers explain in SCMPthe CiADS is a hybrid between a nuclear reactor and a particle accelerator. The main advantage is that greatly reduces the risk of uncontrolled reactionsbut it has another: you can reuse the radioisotopes that normally would be treated as nuclear waste to continue producing energy. Firing beams of protons through these accelerators to bombard the heavy metal makes the uranium-238 give way to a new nuclear fuel: plutonium-239. According to the state media Science and Technology Daily, it is basically turning waste into treasures. According to those responsible, this method is 100 times more efficient than conventional fission and would allow nuclear energy to be converted into “a source of green, safe and stable energy for 1,000 years”, ensuring part of the necessary energy supply for the future. Furthermore, since what would previously be long-lasting waste is reused, the resulting CiADS has a useful life of less than one thousandth compared to conventional waste. The CiADS under construction They are two birds with one stone: China is wildly expanding its nuclear capacity, but it is estimated that it does not have as much uranium of its own and would continue to depend on imports… or to fish it in the sea. With “100 times more efficient” plants, you can get more juice out of what you have. And then there’s the fact that nuclear waste is less dangerous. If everything goes as planned, China will have its first MW-scale CiADS in 2027. It will be then when we check if those theoretical promises achieved by scale prototypes are fulfilled. The CiADS comes at a time when China has emerged as a contradiction in energy matters. They carry years fighting pollution and emissions, but they burn coal. They are a powerhouse in renewables with megastructures and deserts covered by panels. But in the age of AI, it is precisely that coal and gas that is the fuel that allows us to satisfy the demand of data centers at the peak of training. With nuclear weapons, China seeks further reduce your CO2 footprintbut ensuring a future in which it must feed the population, artificial intelligence and a network of technology companies that are doing the most difficult: fighting Western companies without the technological resources of the West. Because right now China doesn’t have the chips or the AI, but yes the energy. And that investment in new generation nuclear plants and, above all, in nuclear fusionrepresents the foundation of what is to come. Everything, that is, if the CiADS works as expected.

His trick is to follow the philosophy of Jony Ive

by

If you work in a more or less large company, you will surely have already suffered one of its endemic evils: meetings. Or rather, have many meetings. Steve Jobs I was clear that they were a huge problem and Larry Page had a hard time solving it because yes, excessive meetings are not something new by any means, although with teleworking they will skyrocket for obvious reasons. And for Brian Chesky, CEO of Airbnb, they are the symptom of a much worse problem within the company. The key to having fewer meetings: manage tasks, not people In fact, the co-founder of Airbnb is clear that this abundance of meetings is not an evil but a sign of aspects to improve within the corporation. To begin with, its size: “It is not because there are no Wednesday meetings. It is because there are too many people“, counted in a talk for Khosla Ventures. The manager’s proposal involves employing a small, high-level workforce: “We want a small, agile, elite and highly qualified team, not a team of mid-range people. And the reason is that each person implies a communication tax.” And he points out another problem that points directly to human resources: mediocre hiring. Basically, in Chesky’s ideology, when someone is not capable of doing a job, they hire people who do not know how to do it either and they also hire more people to carry it out in a kind of empire of incompetence. Each person pulls in a direction, so of course they have to meet to share their progress. And more bureaucracy. Also, lead by example: account which completely removed the layers of management so that only people truly specialized in a given task lead it: “You can only manage the function if you are an expert. You don’t manage people. You manage people through the work.” In a nutshell: you manage tasks, not people. His inspiration: the legendary Jony Ive, now working closely with Sam Altman in building a device with AI. Ive’s philosophy It involves focusing on work and forming a team that designs together.

In 1987 a death was filmed so savage that people had to cover themselves. The trick to achieve it turned RoboCop into a cult work

by

In 1987, the film director Paul Verhoeven gave a twist to action science fiction with RoboCop. In reality, that was a cocktail very much to the director’s liking where there was satire, cyberpunk and police thriller. The difference was that he did not limit himself to telling the fall and rebirth of a hero: he decided to win over the viewer with emotional hammer blows, with a death. so cruel and excessive that it was impossible to look at without feeling uncomfortable. The scene that changed everything. Alex Murphy, the protagonist, appears up to that point as a good cop thrown into a corrupt world, but the film doesn’t have time to build him up calmly, so it does it by the most brutal way: literally, it tear apart in front of the viewer so that, when he returns converted into a machine, he understands that what has been lost is not only flesh, but humanity. Verhoeven explained it with an almost religious and at the same time tremendously cynical idea: “if you want to resurrect Murphy as an all-powerful RoboCop, first you have to crucify him.” And that crucifixion, instead of being symbolic or elegant, is filmed like a physical nightmaredirty and painful, one designed so that the viewer cannot avoid the impact. The slaughter as a narrative. The sequence It is constructed like a public execution, with the criminals laughing in the background, and that is possibly the key to its violence: it is not just that it unlockis that along the way they humiliate him, turn him into a broken toy, and torture him as if the gang were enjoying the show. The scene is escalating until it seems impossiblewith the protagonist trying to understand what is happening to him while his body stops obeying him, and the band acting like real madmen. There is the moral trick of the director of RoboCop: The villains were absolutely grotesque, yes, but the film removes any sympathetic veneer from them and turns them into a total social menace. Thus, when the final shot arrives that puts an end to the execution, the viewer is no longer watching the typical “80s action” film, he is seeing the point of no return that makes the entire film, from that minute on, a story. of loss and revenge. The old school of effects. It is impossible to talk about this classic without mentioning what makes it unique. The how was filmed: no less than under the orders of the legendary Rob Bottin with an artisanal obsession that today seems unthinkable based on meticulously designed prostheses, molds, fake parts and physical tricks. In order for the mutilation to work without putting the actor at risk, a a fake hand From a real mold, it was reconstructed in fiberglass and divided into sections so that it could be “popped” with compressed air and stage blood without the need for explosives near the face. It wasn’t just an effect, it was a device home engineering: internal blood tubes, pressure control, parts that could be assembled and disassembled, and a repeatable explosion pattern to always nail the same result. “Death” was also filmed with a staging designed to hide the real and sell the fakewith raised floors, holes through which to put the real arm under the stage, and a member of the team moving from below a false arm attached with Velcro as if it were a living limb. The underground trick. Plus: Murphy’s death is supported by a secret choreography that the viewer never saw: operators out of shot, hidden mechanisms and an absurd number of hands working to make a second of screen seem like an organic nightmare. Not only that: a foam arm in disguise with a police uniform, a metal structure to hold it, hinges at the “elbow” and even a support anchored to the false floor so that everything could resist the violence of the effect. While the actor was dying and staggering above, below there was a team of professionals pumping blood by hand and adjusting compressed air. Even the shots that “break up” the armor were reinforced with simple but brilliant physical details, such as small charges of talcum powder to simulate fragmentation, a very cheap solution that, in camera, added texture and turned the scene into something tactile, with dust, impacts and material that seems to fall off the body. The Peter Weller doll. Another stroke of genius came with the moment of the auction: for a final shot that in the released version lasts a sigh, a Murphy’s full torsoa sophisticated doll with a latex face made from a mold of the actor, an internal fiberglass skull and mechanisms to move the neck, jaw and body. It was not a static mannequin, it was a creature manipulated by cablescapable of opening his mouth in a silent scream, leaning, trembling and reacting to the shot as if there was still life inside. The execution was designed so that the back of the head “jumped out” with a controlled explosionwith pieces pre-cut to break in a specific way and with the interior prepared with blood and soft fragments, so that the horror felt mechanical but compelling. In addition, the “sweat” detail was added with water sprayas if the doll was breathing for the last time, and a motor with vibration so that the body seems to tremble with fear, an almost obscene trick due to its human nature that returns to artifice. Censorship as an enemy. The most incredible thing is that, even so, what was seen in the rooms was a cropped version. RoboCop’s violence clashed head-on with the rating system of the time, and the film was given an X rating several times, forcing reedit, cut and sacrifice material until a commercially viable qualification is achieved. Paradoxically, the cut that helped save it was one that its own creators considered “shabby” or too obvious, the moment in which Murphy’s arm flies off pulled by a … Read more

The fundamental trick to perfectly control the car’s temperature is a (not) forgotten button on the dashboard

by

Although with the fury of bringing screens to cars There are fewer and fewer buttons, we still find a lot of old-fashioned controls scattered around the steering wheel and the dashboard of the car. However, there is usually a small element (sometimes shaped like a circular knob, which may or may not protrude) that usually looks like a button that goes unnoticed due to its location: it is far enough away that it cannot be easily operated. Spoiler: if you touch it nothing happens. And nothing happens simply because it is a solar sensor or solar load sensor (if we get more technical, a phototransistor), a piece little known to the general public but of great importance as it is the element that the automatic air conditioning uses to regulate the temperature correctly. It is essential to control the temperature of the car More specifically, is located at the bottom of the dashboard and in the central area, attached to the front window. It usually has the speaker grille or the air outlet grille nearby to defog the window. Hence it neither looks good nor is it comfortable to touch. That position makes all the sense in the world: it is one of the best areas inside the cabin to capture sunlight from outside. Precisely the reason for the sensor, since the sunlight that enters a car can reach represent up to 60% heat load that the air conditioning system has to overcome in the search for comfort. A good everyday example: the temperature difference between parking in the same place on a summer day when the sun is shining overhead or doing so at night or when it is cloudy. This solar load sensor It is actually a photodiode which measures the intensity of solar radiation in order to be able adjust climate controlwhich includes the heating, ventilation and air conditioning system. On that hot day in the example, the air conditioning will have to work as hard as possible to cool the cabin as soon as possible. But if it’s night or cloudy, you won’t need to blow as hard. At a technical level, its mechanism is simple: the photodiode moves in an operating range between 0 and 5 Volts, offering more resistance as the light intensity increases, so that the sensor signal decreases as the solar load increases. This signal is what then reaches the control, which gives orders to the system to adjust the speed and intensity. The solar load sensor is not the only one responsible of the operation of the air conditioning, since the vehicle integrates more sensors such as the sensor to measure the interior temperature. And they also have other sensors to turn the lights on or off or configure the mode of the screens and dashboard depending on the exterior lighting. By the way, in some cars there is not only one solar charge sensor, but there are two, one on each side of the dashboard and in that same area adjacent to the front window: they are models that have dual zone air conditioning.

The founder of Ikea was one of the richest men on the planet, but his most famous trick is available to everyone

by

You may like it more or less Ikeabut I don’t think there are many doubts about the success that the company has had throughout its history. One figure was key in his rise. Its founder, Ingvar Kampradwas a different man of his time. The businessman died with billions of dollars in his account and, however, the key that led him to success and that he strictly followed throughout his life was very simple. Hint: never spend more than necessary. Ingvar Kamprad before Ikea. When you imagine the guy who built the Ikea empire, you may think of someone who lived a dream life that very few can achieve. However, if the company is what it is today, it is partly because Kamprad was the complete opposite of those stereotypes. Despite his wealth, he was known for your most frugal habits. Born in Sweden in 1926, his beginnings as a “businessman” began very early. At the age of five he sold matchesand at ten he dedicated himself to selling bikes, fish or even Christmas decorations to his neighbors. At the age of 17, he created Ikea with the money his father gave him for his good grades. Of course, I didn’t sell furniture then, just small utensils for the house. ELON MUSK VS JEFF BEZOS: STAR WARS Kamprad in 1965 Ikea is getting older. It happened in 1956, when Kamprad revolutionized the market and the furniture industry itself with the introduction of flat boxes with furniture to assemble at home. Yes, this began a way of selling the product that has continued to this day and that reduced the company’s costs in exchange for the consumer doing the other part of the work: assembling the furniture. The founder achieved such success that he became one of the richest men on the planet. In fact, when he died in 2018 he was eighth on the world list and had a estimated net worth of 58 billion of dollars. However, if you had met him in life, you would not have thought that you were dealing with a billionaire. Kamprad’s life hack. Talking about the secret of the success of a company like Ikea in an article is nothing short of an act of faith. Surely it is better understood in a book and in a more relaxed way, but we can understand some keys through the figure of its founder. And Kamprad insisted on one thing: saving, and he carried that maxim every day of his life. “Everything we earn we need as a reserve,” said. For example, the man was known for flying economy class, staying in budget hotels, or drive a Volvo 240 GL of 93 that lasted 20 years. In fact, he only gave it up when he was convinced it was dangerous. Kamprad said that he learned to be prudent with money in the small town in southern Sweden where he grew up: “it is in Smaland’s nature to be thrifty.” Example of this it happened in 2014when he returned to Sweden after 40 years of tax exile with clothes “bought only in flea markets.” The haircut anecdote. In 2008, The guardian told a scene which said a lot about the businessman’s personality. Apparently, after paying around 22 euros for a haircut in the Netherlands, he said the price was too high for his usual budget for haircuts, “I usually try to get a haircut when I’m in a developing country. The last time was in Vietnam,” he went on to say. The philosophy of life, to the company. These habits not only represented the beginning of Kamprad’s personal philosophy towards consumerism, but were also to serve as a model for his employees. He New York Times detailed that low-cost flights, meals and hotel stays were initiatives that he promoted among executives. In fact, in 1976 he distributed what was called “Testament of a furniture dealer“, a booklet with guidelines that Ikea employees have followed since then. In it, he details parts of his frugal philosophy, stating that “wasting resources is a mortal sin at Ikea.” His inheritance, his legacy. Decades before his death, Kamprad had placed ownership of the Ikea brand in a complex network of foundations and holding companies. However, these assets were not transmitted to his heirs. Apparently, the Stichting Ingka Foundation, a Dutch entity whose stated purpose is to donate to charities and “support innovation” in design, controls most of the Ikea stores. Additionally, the Interogo Foundation owns the rights to the brand and controls global franchises through a subsidiary. This foundation is managed by a board in which members of the Kamprad family have minority control. That is, the heirs retained some of the wealth and control, but the majority of their fortune is held in charitable trusts. A complicated structure as a result of his desire to preserve Ikea’s unique culture and ensure its long-term survival. Why Ikea. Before finishing this small collection of stories about the man who founded the most famous furniture company, a secret that many do not know. Why is it called Ikea? It is an acronym of the initials of Kamprad’s first and last name, and the initials of the name of the family farm where he was born (Elmtaryd) and the nearest village (Agunnaryd).

Drones revolutionized warfare in Ukraine, now they are going to do it all over the world with one final trick: changing shape

by

If something has become clear after these years of war in Ukraine, it is that drones are no longer a mere complement from the battlefield: they have become a such transformative technology like gunpowder or the Kalashnikov, and are entering a second, even more disruptive phase, driven by artificial intelligencethe miniaturization and the accelerated production. Their next landing is planetary. The second revolution. As we said, drones have gone from being tactical support to becoming a structural factor of modern warfare. Ukraine has shown that an inferior actor in means can degrade a great power with cheap swarms air, naval and land. At the same time, insurgencies, militias and states with few resources use the same logic to compensate for conventional disadvantages. The result, as we will see below, is a global diffusion of precision capabilities at low cost that reduces own risks, complicates defense and makes conflicts more accessible and resistant to resolution. War spine. The trajectory of drones goes from radio-controlled experiments in world wars to smart cruise missiles and platforms like the predator and the reaper in the “war on terror.” The recent turning point is Nagorno-Karabakhwhere an average country combined decoys and UCAVs with artillery to neutralize anti-aircraft defenses and dominate the air without powerful traditional aviation. Since then, the central lesson is that no need be a superpower: simply integrate drones, sensors and indirect fire intelligently to alter the tactical balance. Ukraine as a laboratory. In Ukraine, the drone design, testing and tuning cycle has been compressed to weeks. kyiv has scaled from imported platforms to its own industry that produces millions of unitscombining FPV, reconnaissance, long range and fiber optic guided systems to circumvent Russian electronic warfare. The proximity between workshops and front allows for rapid iterations on sensors, frequencies and flight profiles. Russia responds with mass production and specialized units like Rubikon. The front thus becomes an environment where each innovation is copied or counteracted in a very short time. Swarm globalization. The intensive use of drones has extended to conflicts with a lower media profile. In Africa, dozens of states and non-state actors have built-in armed UAV to internal wars, with markets dominated by exporters such as Türkiye and China. In Myanmar, rebels have converted commercial drones into a substitute for artilleryforcing army withdrawals. In Gaza, Hamas used them to blind Israeli sensors before raids. This shows that technology not only balances power relations, but also increases lethality and makes subsequent stabilization difficult. AI, ammunition and fire economy. The AI integration Drones transform the economy of combat: the cost per useful impact decreases and precision increases. Now there are kits software and hardware that allow existing platforms to locate, track and attack targets with limited human supervision. The practical effect is to reduce the need for classical artillery and increase the efficiency of fire, both on land as in sea. However, this does not eliminate the value of artillery or manned platforms, but rather shifts part of the fire load to systems more fungible and scalablewith clear implications for budgets and logistics. The new unmanned spectrum. And here comes one of the big changes, possibly the least expected. The drone family is expanding and transforming, changing shape and size: from nanodevices for close reconnaissance to enormous ships and underwater vehicles autonomous. The former allow discreet exploration in urban or closed environments, and the latter expand the presence on the surface and under the sea without embarking crews or assuming their risks. Between both extremes, ukrainian naval systems, Chinese XLUUV or AUV as the Ghost Shark redefine surveillance, anti-submarine warfare and area denial operations. The common pattern is to eliminate the need to protect lives on board, making it easier to accept high-risk missions and speed up production. A new generation of contractors. Companies like AndurilAuterion or Shield AI operate with startup logic: short development cycles, strong software integration and commitment to assuming own risk before winning large contracts. Some choose to control the entire chain (hardware and software), others to offer “operating systems” applicable to multiple platforms. This puts pressure on traditional, less agile contractors, and reconfigures the industrial ecosystemwith more mid-sized players competing in specific niches (loyal squires, swarms, mission software). The result is greater speed of innovation, but also more fragmentation of solutions. China, the US and the race. China part with advantage in commercial drones and transfers that leadership to the military fieldwhile investing very heavily in countermeasures after observing the performance of cheap drones in Ukraine. The proliferation of manufacturers of anti-drone systems and directed energy weapons indicates a strategic commitment to control both attack and defense. The United States, despite the accumulated experience, appears out of date in volume and in anti-swarm systems, with dispersed programs and irregular financing, which forces to emergency measures to accelerate purchases and use dual suppliers. This anticipates a long race in which quantity, cost and active defense weigh as much as the individual sophistication of each platform. Strategic limits. This point is often not taken into account. The destructive capacity of drones can lead to overestimating their strategic impact. From there what spectacular operations against high-value infrastructure do not always translate into lasting changes in the control of territory or in the political will of the adversary. Controllers like Radakin they underline that drones and algorithms do not replace the need for a coherent strategy or forces capable of occupying and holding ground. The temptation to build campaigns based on high-visibility specific hits can generate a dangerous gap between tactical success and strategic results. The era of eternal wars. All this breeding ground leads to a final scenario: by reducing costs and risks for those who prolong the combat, drones favor conflicts. no clear outcome. Statistics show fewer decisive victories and fewer peace agreements since the 1970s, while stagnant wars increase. In this context, drones provide continuous capacity for harm to actors who would otherwise be forced to negotiate or give in. The probable result is more long wars, distributed … Read more

AEMET has just talked about the December long weekend and it is bittersweet news because the “good weather” in December always has a trick

by

Yes ‘negative NOA‘, yes ‘storm train‘, but what AEMET says is that, during the bridge (after some persistent rain in the north), what we are going to have is a predominance of sun and higher than normal temperatures. How is it possible? What dark atmospheric dynamics are conspiring to give us good weather on the Constitution Bridge? The rhombus phenomenon. That’s what he called it meteorologist Luismi Pérez on Cadena Ser and the truth is that the explanation is so visual that it can help us understand what is happening. “Rhombus” is a colloquial way of defining an isobaric configuration that diverts the cold to North America and gives stability, little rain and high temperatures to our country. And what does it take for that to happen? Four masses of air are needed to achieve this: a robust anticyclone in Newfoundland and Greenland another anticyclone in the Mediterranean area a storm in the Azores and another in the Scandinavian peninsula In the image above it is still difficult to see, but arranged on the isobar map “they form an approximate figure of a rhombus.” Why it is important. Meteorologically speaking, the rhombus describes a type of atmospheric block very characteristic: a reconfiguration of the polar jet and the trajectory of the storms that takes us away from the coldest scenarios. Yeah the face is the train of stormsthis is the cross: short periods of stability and good temperatures. What we can expect in the coming days. As Pérez explainedthis rhombus “makes” the very cold air accumulated in Greenland slide towards the west; that is, towards North America, instead of falling on Europe. In addition, Spain (being under the influence of the Azores storm and the Mediterranean anticyclone) is assured of westerly and southwesterly winds, which are more temperate and pleasant. What we can expect in the long term. Because in the background there is something more serious: changes in the atmospheric circulation of the Atlantic Ocean. That is to say, the increase in the number of episodes of stability, clear skies and absence of fronts in autumn and winter. Something that can be perceived as “good weather”, but that aggravates the structural drought and complicates water, agricultural and energy planning. Luckily, it looks like it won’t last long.

Volkswagen has presented its “most intelligent car to date” in China. The trick is that Volkswagen hasn’t done it

by

Volkswagen prepares the launch of the ID. UNYX 08an electric SUV developed together with the Chinese firm Xpeng that will hit the market in 2026. For years, Volkswagen enjoyed a large presence in China. However, currently, firms such as Xiaomi or BYD have overtaken them to the right with their proposals and technology. The German group has had no choice but join forces with the Chinese Xpeng to continue competing in this very competitive market. And the greatest exponent of this alliance is this same car of which we are going to tell you all the details. Strategy to come back in China. The German brand has lost positions in this market since 2020, when electric vehicles began their massive expansion in the country. Now it is trying to recover the lost ground against local manufacturers such as BYD and Geely through this technological alliance with Xpengwhich provides its G9 platform and its connectivity and driving assistance systems. Design speed. The ID. UNYX 08 was completed in 30 months, a time that according to Volkswagen It is more than 30% lower than usual. This acceleration responds to what the company calls “Chinese speed”, a concept that reflects its need to adapt to the pace of the local market. The German manufacturer affirms having managed to “fully integrate into China’s automotive ecosystem” thanks to local alliances and its own research and development capabilities. The figures of the new SUV. The vehicle measures 5 meters long, 1,954 meters wide and between 1,672 and 1,688 meters high, with a wheelbase of 3,030 meters. These dimensions exceed those of the Xpeng G9, the model on whose platform it was built. It will be available in two configurations: a 230 kW rear motor or dual motor with 140 kW front and 230 kW rear. will ride LFP batteries from CATL, with a range of more than 700 kilometers according to the CLTC cycle, and will support 800-volt fast charging. Technology at the service of the Chinese driver. The ID. UNYX 08 will incorporate L2++ level driving assistance with the capacity for autonomous operation “from parking to parking” both in the city and on highways. It will also have OTA (Over-the-Air) updates and an artificial intelligence assistant based on advanced language models. Volkswagen presents it as “its most intelligent model to date.” The plan to get back into the fight. This SUV is the first of the two models agreed between Volkswagen and Xpeng in 2023. It will be assembled in collaboration with Anhui Jianghuai Automobile Group, a partner with which Volkswagen created its first joint venture in China in 2017 dedicated exclusively to new energy vehicles. The ID family. UNYX, which already includes the 06 (a compact SUV) and the recently unveiled 07 (an electric sedan), thus expands into the medium-large SUV segment. What’s at stake. For Volkswagen, this launch represents much more than a new product: it is a litmus test on its ability to compete with Chinese manufacturers in its own territory. The Asian market has become the main battlefield of electromobility worldwide, and the German brand needs to demonstrate that it can offer cutting-edge technology without losing its identity. We’ll see if the ID. UNYX 08 convinces drivers in China. If you do so, it will set the course of your strategy in the country.

The gesture is automatic for millions of people who get up in the morning: take a coffee capsule, put it in the coffee maker and press the button to have hot coffee in a few seconds. However, this convenience can have a hidden cost to our health. This is something to what Nicolás Olea concludesprofessor emeritus at the University of Granada, who has issued an alert about the high exposure we face in endocrine disruptors. What are disruptors? After all, they are chemical substances that are actually present in a large number of products that we consume on a daily basis. As their name indicates, they have a direct relationship with the endocrine system. by altering its functioning. Specifically, its objective is hormones, those substances that They act as messengers within the body to give messages between cells, and that with these disruptors you can end up giving signals that are not true. They are present in many products. food products, bottles and plastic cups, tea bagsmicrowave popcorn, the containers or even the sun creams They have this type of substances that are the order of the day right now and that directly attack our body. The consequences. For the professor, the effects are clear: they alter the thyroid, promote obesity, diet or even infertility. All this documented with different essays in which it is directly pointed out that the lack of fertility in Europe It could be due precisely to this poor quality of semen or ovarian reserve as a result of the high combination of different endocrine disruptors that we have in our body. And precisely women can be more affected due to the great variability of hormones that they have in their body throughout their lives, since the hormonal cycle in a teenager is not the same as in a pregnancy. The coffee problem. Once we have all this clear, we return to the classic coffee capsule that we use every morning. In this case we prepare it with high pressure and high temperature to obtain a good result. The problem is that with this high temperature the plastic from which the capsule is made can melt and end up with a coffee riddled with microplastics that contribute to exposure to endocrine disruptors. A plastic that is usually polystyrene and epoxy resin that acts as glue. But it is not something that is limited to the consumption of coffee capsules, it can also happen with plastic cups if a very hot liquid is poured or in plastic bottles that are reused. Why are they allowed? If it is so bad to consume this type of product, the question is obligatory. In this case, the professor points out that right now there is no clear regulation on endocrine disruptors. Where much emphasis is placed is whether a particular chemical compound is categorized as carcinogenic, where a quick ban is applied. But if we talk about disruptors, the truth is that there are more legal loopholes, unless it is decreed as toxic for reproduction where you can choose to limit it in the market. The cocktail effect. Although the industry argues that the quantities released by a single capsule are minimal and within the law, experts like Olea warn of two key problems: accumulation and the “cocktail effect.” And the effects of these substances are seen above all in the long term in the body and with chronic exposure. That is why it points out that current legislation does not take into account this combined effect of all sources of exposure to apply regulation. Because not only is it a coffee capsule in isolation, but the pesticides that a food may have, the chemicals in the cosmetics that we put on our faces or even the plastic of the container where we heat up the macaroni to eat. Other dangerous situations. Because indeed, the coffee capsule is not the most striking thing that the expert has commented on in this case, since the interior of a brand new car is also dangerous for our body. Although many people love the smell that remains in the cabin when it is new, the reality is that it is loaded with different chemicals such as phthalates, phosphorus or bisphenols. Very volatile substances that appear especially when the car has been in the sun for a long time and that can end up in our body.
