While the whole world looks at oil, Venezuela’s true treasure is hidden in the basements of London: its gold

by

Perhaps the great treasure of Venezuela not oil. In fact, since the United States attacked Caracasa series of theories have begun to be heard loudly that have a common denominator: the greatest Venezuelan loot is thousands of kilometers from the nation, under the soil of the capital of the United Kingdom. The gold trapped in London. Yes, under the streets of the cityin the vaults of the Bank of England, remain immobilized about 31 tons of gold belonging to Venezuela, an asset that in 2020 was valued around 1.4 billion pounds and that today it is worth much more after the strong rebound of the metal price. The capture of Nicolás Maduro for the United States has returned This issue is brought to the international forefront, reopening a question that has been without a clear answer for years: who really has the right to control these reserves. Although global attention often focuses on Venezuelan oil, gold represents about 15% of the country’s foreign reserves and has become a key piece of a political, legal and geopolitical pulse that far transcends Caracas. Recognition and blocking. The origin of the blockage dates back to 2018after a disputed presidential election and the tightening of sanctions promoted by Trump during his first term. The United Kingdom, along with dozens of countries, stopped recognizing Maduro as legitimate president and, under pressure from the Venezuelan opposition, refused to authorize the repatriation of the gold, alleging the risk that it would be used to prop up an authoritarian regime or directly diverted. Added to this, as later revealed former national security advisor John Bolton, an express request from Washington for London to maintain the blockade, which placed the British central bank and the Government at the center of a battle that mixed international law, sanctions and diplomacy. Bank of England A judicial labyrinth. In 2020, Caracas went to court British to claim the gold, arguing that they needed those funds to deal with the pandemic. However, the process became complicated when Juan Guaidó, then recognized by London As interim president, he also claimed ownership of the reserves. The litigation led to a legal tangle about who the Bank of England should obey, a question that remains unresolved even after Guaidó lost international recognition. The result is a legal limbo in which the gold remains immobilized, without any of the parties being able to dispose of it. Piracy accusations. From the Chavista environment, the retention of gold was denounced as an act of “piracy”an accusation made at the time by Delcy Rodríguez, which was later marred by the scandal known as Delcygate following his alleged secret trip to Madrid in 2020 despite an EU entry ban and the alleged sale of Venezuelan bullion. Although Rodríguez has adopted a more conciliatory tone After the fall of Maduro, offering cooperation to the United States, the British position remains firm: Foreign Minister Yvette Cooper has reiterated that London maintains political pressure because it considers it key to force a democratic transition, even underlining the formal independence of the Bank of England in the management of assets. The dangerous precedent. The Venezuelan case is not an exception, but rather part of a trend increasingly controversial: the immobilization of sovereign reserves in a context of growing geopolitical confrontation. We have told it: after the Russian invasion of Ukraine in 2022, Western countries froze about 300,000 million of dollars from the Russian central bank, largely deposited in Eurocleara measure that has generated tensions with Moscow and has revived the debate about the security of keeping assets abroad. Historically, these sanctions have been rare but not unprecedented, from the Soviet confiscation of Romanian gold in 1918 to blockades of countries like Iran or North Korea in the second half of the 20th century. Global distrust. Thus, the climate of uncertainty is leading many countries to rethink where do you keep your reservesdriving repatriation movements and fueling the recent gold rally as an active refuge. For analysts and central banks, the Venezuelan episode is a clear warning of how politics can interfere with assets that were traditionally considered untouchable. While the Bank of England remains officially silent (and many ingots), Venezuelan gold remains buried under London, converted into a symbol of an increasingly international financial order. more fragile and politicized.

China bets on liquid air to stabilize its largest solar sea on the roof of the world

by

In the vastness of Qinghai province, where the Tibetan plateau merges with the Gobi desert, dust and rock they have given up their domain to a mega-project of 610 square kilometers. This “sea of ​​silicon”—the size of the city of Madrid—is home to seven million photovoltaic panels that have transformed the ecosystem: the shade of the plates retains humidity and allows thousands of “photovoltaic sheep” graze today where before there was only sand. However, this massive deployment encountered a physical barrier. As researcher Wang Junjie explainssolar and wind energy are “random and intermittent”; When the sun sets in the Gobi, the power grid shakes. To stabilize this giant, China has gone beyond conventional lithium, betting on liquid air storage. White giants in the desert. On the outskirts of the city of Golmud, a row of white tanks stands sentinel against the horizon. It is the world’s largest liquid air energy storage (LAES) project, dubbed by Chinese media as the “Super Air Power Bank.” According to the Xinhua agencythis facility of the state-owned company China Green Development Investment Group (CGDG) has entered its final commissioning phase. It is not just any battery: its capacity is 60,000 kilowatts (60 MW) and it can release up to 600,000 kWh per cycle, a discharge capable of sustaining the daily consumption of tens of thousands of homes. Physics against lithium. Why has China opted for this technology instead of its popular lithium ion batteries? The answer lies in scale and geography. While lithium is ideal for mobile devices or cars, on an industrial scale it faces cost and degradation problems. Air has an advantage that is difficult to match: it is there and it costs nothing. AND, as CleanTechnica remindswhen it becomes liquid air its density skyrockets, up to 750 times more than that of normal air, which allows energy to be stored in large quantities without dams or geographical conditions. The alchemy of cold: From gas to liquid at -194°C. The operation of the system is a feat of cryogenic engineering. As detailed by Xinhuathe process is divided into three critical phases: Load (Compression): During the day, surplus solar from a nearby 250 MW plant powers giant compressors. The air is purified and cooled to -194 degrees Celsius (-317°F). At that extreme temperature, the air becomes liquid. Heat recovery: The heat generated during compression is stored in high-pressure spherical tanks to be reused. Discharge (Expansion): When electrical demand rises or the sun disappears, the liquid air heats up. When vaporized, its volume expands explosively (750 times), driving a turbine that generates electricity again for the grid. This cycle, according to researcher Wang Junjieachieves over 95% cold storage efficiency and 55% “round trip” efficiency, harnessing what would otherwise be waste heat and eliminating the need for rare materials. A global laboratory on the “roof of the world.” China is not the only nation in this race. The United Kingdom waits to complete a similar plant in Manchester by 2026, and South Korea too has made progress in this technology. However, the Chinese scale is, again, incomparable. However, the success of these projects in Qinghai is due to centralized planning which combines three sources: solar, wind and hydroelectric. At 3,000 meters above sea level, the cold, pure air improves the efficiency of the panels, and the electricity generated is already 40% cheaper than that of coal. This energy not only illuminates homes; It powers the data centers that power China’s Artificial Intelligence, using the plateau’s frigid air to cool the servers. From the factory to the engine of the world. As Professor Ningrong Liu reflectsChina no longer wants to be just the “factory of the world”, but the “engine” of that factory, exporting its engineering and its green network model. Golmud’s project It is the symbol of a paradox: the country that emits the most CO2 is also the one that builds the fastest carbon exit. In the silence of the Gobi, between cryogenic tanks and sheep herders, China is demonstrating that the air we breathe can literally be the fuel that sustains the 21st century.

A Russian family lived isolated in Siberia for more than 40 years. He didn’t know about World War II or the space race.

by

In the cold, vast and desolate siberian taiga one would expect to find spruce trees, maples, streams and acres covered in frozen silt. Maybe (hopefully) some lone pso or wolf. What no one would include on that list is what he discovered around mid 1978 an expedition that flew over a mountain located more than 240 km from any human trace. There, in the middle of the Abakan mountain rangea group of geologists came across a family that had been isolated for 42 years. Its story still fascinates today. And that cabin? Such a question must have been asked 47 years ago by a group of Soviet geologists flying over the Siberian taiga, an area rich in oil, gas and mineral reserves. He ran summer of 1978 and the team, led by Galina Pismenskaya, was traveling by helicopter in a region of Siberia located 160 km from the border with Mongolia when the pilot saw something between the trees. Something unexpected. A rudimentary cabin with a small garden. In most parts of the planet, such an image would be of little interest, but Pismenskaya’s team was supposedly in an unpopulated area. In fact, the Soviet authorities were not aware that anyone lived there. The nearest houses were supposed to be more than 200 kilometers away, so the question was obvious… What the hell was that shack doing there, built next to a stream, among trees? They were so intrigued that geologists decided to land. “We come to visit”. The impressions of Pismenskaya and her colleagues when approaching the hut we know them thanks to Vasily Peskova Russian journalist and traveler who would later interview the protagonists of that story to collect it in a book. Upon landing, the researchers found a hut made with the little that the taiga offered: bark, branches, trunks and pieces of wood blackened by humidity. On one side there was a tiny window. On the other side there was a door through which an old man appeared. “Like something out of a fairy tale”, would relate some time later Pismenskaya, who recalled that the man was barefoot, was wearing a patched shirt and pants and sported a scraggly beard. “He seemed scared. We had to say something, so I started: ‘Greetings, Grandpa! We’ve come to see you.’” The fact is that that old man was not alone. When they entered the hut with him, the geologists discovered that he lived with his four children. They all shared that wooden construction without rooms, blackened by smoke, cold and with the floor covered in shells. Upon seeing the new arrivals, one of the young women began to pray, scared. Another, hidden behind a post, ended up collapsing from suffocation. Logical. The family had not seen another human for four decades. Dating back to 1936. The old man in question was called Karp Osipovich Lykov and the fact that he lived there, in conditions almost medieval people, hundreds of kilometers from any hint of civilization and surrounded only by his children, is explained in light of what happened in Russia at the beginning of the 20th century. Just like his Karp family was an old believera member of a church split from Orthodox Christianity that embraced the ancient liturgy and ecclesiastical canons. The path of Karp’s coreligionists had diverged from the Russian Orthodox already in the 17th century, after Nikon’s reformwhich made them outcasts. This had happened in times of Peter I…and with the Bolsheviks. This harassment affected the Lykov family directly. Around 1936, a patrol shot his brother on the outskirts of the village where they lived, so Karp made a radical decision: he gathered his wife Akulina and the two children they had at the time (Savin, nine years old, and Natalia, two) and escaped into the forest. Literally. He walked away as far as he could. Without looking back and with light luggage that included just a handful of seeds, a rudimentary spinning wheel, a couple of jugs to boil water and the clothes they were wearing. Once in the taiga, the family built a cabin with what they had on hand, set up a garden and continued with a life marked by isolation, their beliefs and deprivation. In 1940 the couple had their third son, Dmitry; and four years later the fourth and last daughter, Agafia, was born. Back to history. The Lykovs continued with that life until Osipovich’s helicopter located them in the summer of 1978. It may sound strange, but the family had settled in a particularly inhospitable place. No one saw them before because no one looked there. The marriage moved as he encountered difficulties, moving further and further away from the villages and towns, until settling at a point located more than 240 km of the nearest settlement. Not even the Soviet authorities were aware of the existence of that family. The consequences of that isolation are obvious. For the Lykovs, time, politics, science… stopped dead in 1936. The family did not know that Europe had been shaken by World War II, nor that man had stepped on the Moon in 1969, nor was it aware of the space race, the name Kennedy or the Beatles did not ring a bell… Some family members marveled at seeing a television or items as seemingly simple as matches or a roll of transparent cellophane. Fascinating yes, bucolic no. The Lykovs’ 42 years of isolation were, however, hardly bucolic. Their cabin was built next to a stream and the forest offered them wood, fruit and even game, but the harsh conditions of the taiga subjected them to a constant test. Especially the first years. Agafia even told how towards the end of the 1950s the family faced their peculiar “years of hunger”, during which they had to decide whether to eat the little they harvested or save some of the seeds to grow them the following year. “We were hungry all the time,” he admits. Years later the family suffered a frost … Read more

This is the largest battery-powered locomotive in the world

by

There are places where scale determines everything, and Port Hedland is one of them. At this point in the northwest of Australia, a locomotive has appeared that seeks to make its way into a territory dominated for decades by diesel. Progress Rail presents her as the locomotive battery-powered electric largest in the world, and the relevant thing is that it is not enough for a photo, but to fit into a real mining operation. It’s the kind of move that, if it works, could have practical implications in a sector little given to change. From an industrial point of view, the key is not only that the locomotive exists, but that it is already in the place where it is expected to work. Fortescue says that These electric locomotives are intended to operate on its mining network with the stated goal of reducing the use of fossil fuels and improving the energy efficiency of the railway system. The interest of the announcement lies in this direct application, in an infrastructure designed for constant and demanding loads. From now on, it will be the actual operation that will determine whether this bet can be scaled beyond the first units. From diesel to batteries at the heart of Australian mining The locomotive that has arrived in Western Australia It is an EMD SD70J-BBone of Progress Rail’s developments in railway electrification using batteries. On a technical level, it combines an eight-axis architecture with a high-capacity battery, which in the Joule series can reach 14.5 MWh. Regarding weight, Progress Rail speaks of 265 tons in a recent communication, while its technical sheet for the model places it at 245 tons, a difference that the documentation itself does not clarify and that may depend on the configuration. The route followed by the locomotive helps to understand where this initiative is. Shipped from Sete Lagoas, in Brazil, the unit was transported by sea bordering Africa, passing through South Africa, before arriving in Australia. This type of logistics is common when dealing with individual teams and not entire fleets, and fits with the idea of ​​​​a gradual introduction. The move alone suggests that the project is still in an early phase of operational deployment. Fortescue defines these units as Battery Electric Locomotives, or BEL, a concept that transfers principles already known in other electrical fields to heavy rail. In this case, the locomotive runs on energy stored in batteries and recovers part of that energy during brakingan especially relevant aspect on loaded and sloped routes. The company has pointed out that This system makes it possible to recover between 40% and 60% of the energy used, although this figure depends on the profile of the line and the type of operation. Fortescue’s environmental speech accompanies this deployment with ambitious figures. The company ensures that your Electric locomotives could collectively eliminate about a million liters of diesel each year, provided they operate according to planned scenarios. It has also highlighted that the energy used comes from its own renewable infrastructure in the Pilbara, a key element for the reduction of emissions to be effective. Progress Rail set the noise level of this locomotive below 70 dB during operation, a low record by heavy rail standards. In comparative terms, a conventional diesel locomotive is usually above this threshold, especially during acceleration and low-speed work. This difference is not only a matter of comfort, but also influences working conditions in industrial environments where machines operate for long shifts. The acoustic reduction thus adds to other operational changes derived from electrification, beyond energy consumption. From a technical point of view, the most direct comparison is with heavy-duty diesel locomotives that dominate railway mining today. These machines stand out for their autonomy and known logistics, while the electric alternative introduces new variables, such as the management of stored energy and recharge times. Compared to hybrid proposals, which combine thermal engines and batteries, the SD70J-BB is committed to a completely electric scheme, with fewer elements associated with combustion and with the potential to simplify part of the maintenance. In return, dependence on energy infrastructure and stricter planning increases. The arrival of these locomotives cannot be understood without the role of the companies involved. Progress Rail, acquired by Caterpillar in 2006offers diesel locomotives and also alternatives such as batteries, hybrids or hydrogen, and is now seeking to place these solutions in high-demand environments. Fortescuefor its part, is trying to reduce the energy footprint of one of the most intensive logistics chains in mining, and fits these units into its public narrative of decarbonization. From now on, the focus shifts to the operation. It remains to be seen how this locomotive will behave in continuous service, what its real availability will be and what demands it will add in maintenance and energy infrastructure. It will also be key to observe whether the estimates on fuel savings and efficiency are confirmed with data accumulated under real load conditions.

This frog is one of the most colorful creatures in the world. Photographic tourism is costing it its existence

by

The frog you see above is one of the most striking amphibians that exist, so how can you not stop to take a photo of it if you find it in your path? Well, in practice it is difficult for you to come across one if you live in Madrid, London or New York because this frog that looks like it’s from another galaxy is native from a very specific place in India: the evergreen forests of the Western Ghats mountain range, at an altitude of between 900 to 1,200 meters. So if the mountain does not go to Muhammad, Muhammad goes to the mountain: just as there are those who leave to Mexico to swim with wild orcasthere are people who prepare a getaway on their own to immortalize the galaxy frog, which is its name. These unregulated photographic excursions are already taking their toll: an entire group of specimens has disappeared from the rainforest. As you can deduce from the photograph of the galaxy frog, it gets its name from its cosmic appearance, with a black background and little black spots that look like stars. It is not an appearance that goes unnoticed, but between the fact that it is similar in size to the tip of a finger and that they hide in small spaces such as cracks under rocks, fallen leaves and decaying trees, It is not easy to see them with the naked eye.. Going to photograph an endangered species is not the best thing for the species. Handle it carelessly, either And it is not easy to see them simply because they are disappearing from the face of the Earth: galaxy frogs have a conservation status classified as “threatened” that is getting worse, according to this study published in Herpetology Notes.In the paper They point directly to one of the main culprits: uncontrolled photographic outings, insofar as they cause alterations and changes in behavior that have an impact on the feeding and reproduction of the frogs. The study’s research team, led by Rajkumar K. P, a scientist at the Zoological Society of London, has been monitoring that area of ​​​​the jungle since 2019, which has allowed them to follow the population of the Melanobatrachus indicus (its scientific name) over time. Back in 2020 they discovered a group of seven galaxy frogs hidden under some logs. Via: Drjpmenon When they returned to the area after COVID-19, they found that this group had disappeared. So, all the alarms went off: What had happened to that group of frogs? Well, two summers where different groups of photographers came en masse, trampling the area and moving the logs looking for: 1. the frogs. 2. get the perfect composition to take the ideal photo. As the investigation states: “The photographers knew the microhabitat of the species through publications and local trackers and moved numerous logs while searching for the frogs.” The researchers are aware of groups of up to six photographers who came to the place eager to photograph the frogs. And not only that, they often moved the specimens to place them on moss or logs, so that they could take a photo with a more attractive background. For frogs, it not only involves the presence of man or undergoing changes in their location and that of the elements where they hide and find food, but also enduring repeated manipulations and powerful camera flashes to illuminate the scene for hours. Touching such a sensitive wild animal without biosafety protocols is not a good idea: stress, heat, potential illnesses… are some of the conditions they suffered, such as pick up the paper. One of the trackers assured the researchers that two small frogs perished during the sessions, although the scientists could not verify this. The investigation concludes with a series of good practicesa measure that researchers say should be established in the form of ethical standards for nature and conservation photography. This is not a study against natural photography, since as Rajkumar explains, done correctly it can be the best ally: “It’s a huge resource to help conservationists better understand things like animal distribution and behavior, and the resulting images can educate others about these incredible species. (…) However, irresponsible photography can turn that resource into a danger.” Rajkumar takes this sad episode as an example as “a strong warning about the consequences of unregulated photography” but that without careful and responsible management “we run the risk of disappear from the planet forever“.

Ukraine has asked Russia if they stop for Christmas like in the First World War. The answer could not have been more Russian

by

The inevitable reference when talking about a Christmas break in the middle of a conflict is the spontaneous truce December 1914in the first months of the First World War. On several sectors of the Western Front, British and German soldiers left the trenches, exchanged cigarettes, sang Christmas carols and even played football in no man’s land. Ukraine has remembered it, but it is going to be complicated. The first time. On that occasion of the First World War, the truce was not ordered by the commanders nor was it part of a political negotiation: came from belowof human exhaustion in the face of a war that had not yet shown all its industrial brutality. Precisely for this reason it was never repeated. The high command considered it dangerous, subversive and incompatible with a modern total war. Since then, Christmas has been used many times as a rhetorical symbol of peace, but almost never as an actual interruption of fighting. The Ukrainian proposal. In this historical context full of symbolism, Ukraine has raised the possibility of a ceasefire during Christmas, an idea carefully formulated so as not to appear as a disguised surrender. Zelensky has spoken of a specific pauseespecially linked to attacks against energy infrastructure, at a critical time of winter and with the civilian population as the main collateral victim. At the same time, kyiv is preparing a new package of peace proposals backed by European partners and channeled through the United States, with the expectation that Washington will offer top-level security guarantees if Moscow rejects the plan. Zelensky, however, has shown caution and has lowered any expectations of a quick deal, publicly assuming that Russia may choose to continue the war and that, in that case, Ukraine will ask for more sanctions and more weapons. Officers and men of the 26th Division Ammunition Train playing football at Salonica, Greece, on Christmas Day 1915 The Russian response. The Kremlin’s reaction to the “Christmas break” has been immediate and bluntalmost ritual in its formulation. Dmitri Peskov has discarded any temporary ceasefire, including a Christmas truce, with an argument that Moscow has been repeating for months: a pause would only serve for Ukraine to regroup, rearm and prolong the conflict. In official Russian language, the word “truce” is presented like a trapwhile the word “peace” is reserved for a scenario in which Russia has achieved all your strategic objectives. According to Peskov, Moscow is not ready to replace a comprehensive negotiation (in their own terms) for “momentary and non-viable” solutions. The logic is clear and brutal: either the Russian framework of political and territorial victory is accepted, or the war continues without sentimental interruptions. Territory, guarantees and red lines. Behind the exchange of statements lies the real core of the conflict. Russia demands that Ukraine rspread to wide areas of its territory, accept permanent limits on its armed forces and rule out any future accession to NATO. Ukraine, for its part, rejects hand over the Donbaseven under ambiguous formulas such as a supposed demilitarized “free economic zone,” and remembers that it was already betrayed once when it renounced its nuclear arsenal in 1994 in exchange for security guarantees that did not prevent the invasion. Polls show that a clear majority of Ukrainian society opposes withdrawing from the east and is willing to continue fighting, a domestic factor that greatly limits Zelensky’s political margin even as international pressure increases. Christmas without miracles. The proposal for a Christmas break actually exposes the abysmal distance between the war that we evoke in historical memory and the war that is being fought today. In 1914an improvised truce was possible because the soldiers still saw each other as human beings confronted by accident. In 2025, the war in Ukraine is a conflict of objectives strategic, existential red lines and cold calculation of power, where each day of pause is measured in kilometers of front, ammunition reserves and operational advantages. The Russian response dry and distrustfulis not only “very Russian”: it is confirmation that, in this war, Christmas has no capacity to suspend the logic of the conflict. Unlike more than a century agothere is no room for carols between the trenches, only for official statements that remind that, for Moscow, peace does not begin with a truce, but with the political defeat of the adversary.

Europe is the world leader in heat pump manufacturing. The only problem is that Europeans don’t use them

by

Not to get grandiose, but Europe has never had so many renewables underwayhad never made so much clean technology and never had talked so much about energy independence. And yet, winter has arrived again and the ritual is always the same: turning on the heating still means burning imported gas. Although if we reach this point it is not for lack of alternatives, because they are there. The problem is much more mundane: in much of the continent, heating with electricity it’s still more expensive than doing it with gas. The energy shock that changed everything. A recent EMBER report has detailed how Europe abruptly lost access to cheap Russian gas and had to replace it with much more expensive liquefied natural gas in a highly volatile global market. The result was an unprecedented price shock: an accumulated extra cost of 930 billion euros during the energy crisis. More on fossils. Far from being a problem caused by the green transition, the document indicates that the impact was concentrated precisely in the sectors most dependent on imported fossil fuels. Energy-intensive industries reduced production and, in many cases, never returned to pre-Ukraine war levels. This reading coincides with that presented by researcher Jan Rosenowwho rejects the idea that dismantling climate policies would make energy cheaper. The problem, he maintains, was not going too fast, but rather having delayed electrification for decades and having kept gas as the pillar of the system. Here the central contradiction emerges. According to EMBERheat pumps are a mature, efficient and strategic technology: they produce between two and three times more heat than a gas boiler for each unit of energy consumed. Even if that electricity came entirely from a gas plant, the net fuel savings would still exist. However, in practice, the technological advantage is diluted in the bill. In most EU countries, electricity costs 2 to 4 times more than gas for the end consumer. The average electricity-gas ratio in the EU is 2.85, and in some member states it exceeds 4. The problem: the pricing structure. As pointed out in the consultancynon-energy costs —taxes, tolls and public policy surcharges— can represent up to three quarters of the final price of electricity, while gas maintains a much lower tax burden. The result is an obvious distortion: the most efficient technology appears expensive and the most polluting technology appears affordable. You save but not. For an average home, this anomaly has a direct effect, since changing systems reduces energy consumption, but it does not always reduce the bill. And when that happens, adoption slows down. Furthermore, the data confirm that this is not a cultural or climatic issue, but rather an economic one. In countries like the Netherlands, where electricity is only slightly more expensive than gas, heat pump sales are soaring. On the other hand, in Germany, Poland or Hungary —where electricity can cost more than three times as much as gas—, adoption is much lower. The lever that remains to be activated. Solutions exist and many are immediately applicable: transferring the costs of electricity policies to public budgets, reducing electricity VAT, taxing fossil gas more coherently or implementing specific rates for heat pumps. From there, technological deployment is no longer a promise, but a reality. In fact, Europe leads the global heat pump industrywith manufacturers such as Bosch, Vaillant, NIBE or Danfoss, and with industrial projects that already operate on a large scale. These are not prototypes or pilots, but rather functioning infrastructure. Real limits and tensions. None of this eliminates obstacles. Europe still need gas to stabilize its electrical grid. The infrastructures are stressed, the flexibility of the system is insufficient and any cold winter can send prices skyrocketing again. Added to this are the physical frictions of the transition. The massive expansion of offshore wind in the North Sea is generating unprecedented conflicts between countries due to the so-called “wake effect”, which reduces the production of neighboring parks. Electrification is not only a matter of political will, but also of technical coordination and supranational planning. The anomaly that Europe has not yet corrected. Europe already has the technology, the industry and the climate goals. What it has not yet corrected is a basic anomaly: fiscally penalizing electricity while de facto subsidizing fossil gas. As long as that distortion persists, heat pumps will continue to advance more slowly than data, engineering, and economic common sense would allow. As the EMBER report concludeselectrifying heating is not a green whim, but a strategy for energy security, industrial competitiveness and price stability. The transition is not about inventing new machines, but about deciding which energy is made cheaper and which is left behind. And today, in Europe, that decision continues to be reflected—very clearly—in the invoice.

Telefónica leaves Wall Street through the back door. Goodbye to almost four decades in the largest market in the world

by

Telefónica has started the procedures to delist your shares from the New York Stock Exchangewhere it has been listed since 1987. The securities will stop trading on Wall Street in a matter of days once the documentation is filed with the SEC. The telecom will only maintain its listing in Madrid, in the Spanish continuous market. Why is it important. The movement closes a symbolic chapter that began when Telefónica became the first Spanish company to be listed on the largest market in the world. But the symbolism was left behind: today maintaining that presence involves high administrative costs and regulatory demands that no longer compensate. The trading volume in New York is residual and investor interest is practically non-existent. The context. Telefónica’s stock has fallen more than 90% in the last fifteen years. Its current valuation is on the floor, very far from that giant that in the nineties became the most valuable company in Spain. The dividend, which for years was the main attraction for conservative investors, has been successively cut, the last time this quarter. Buying in Madrid is more direct, cheaper and with the same liquidity as in New York, where securities are hardly traded. Between the lines. This decision fits into the strategic plan presented in November by Marc Murtra, focused on aggressively reducing costs. Telefónica has been lowering its blinds on all fronts: Sold subsidiaries throughout Latin America except Brazil. Reduced the dividend. Presented an ERE which is ending its negotiation phase. And now it is abandoning stock markets where being present no longer adds value. Also will stop trading in Lima. The figure. 4,554 departures are contemplated by the ERE that was agreed this Wednesday with the unions, 26% of the workforce in Spain. Cost savings are the obsession of the new management: 3 billion annually until 2030. Yes, but. Investors who have ADR certificates (American Depositary Receipts) will be able to exchange them for common shares in Spain or hold and trade them in US over-the-counter markets. Telefónica will provide both options, although it is evident that it prefers the first. The background. The exit from Wall Street is not an isolated or recent decision: The telecommunications sector has lost interest from investors, especially in Europe. It is a mature business, highly regulated, with tight margins and little ability to surprise. Telefónica today is a very different company from the one that debuted on Wall Street: smaller, more regional, more European. Its new strategy focuses on four markets (Spain, Germany, the United Kingdom and Brazil) and on consolidating itself as a reference operator with profitable scale, in addition to increasing its focus on technological solutions. Marking agenda. Wednesday’s day at the Distrito Telefónica offices north of Madrid was hectic. The contrast. When Telefónica went public in New York in 1987, it placed certificates worth $375 million, the largest influx of European capital on Wall Street up to that time. The telecom was then majority owned by the State and its debut was seen as a milestone of internationalization. Today it leaves unnoticed, recognizing that the regulatory burden and administrative costs of the SEC outweigh any benefits. Go deeper. The obligation to report detailed information to the SEC was useful at the time: thanks to it, data such as the price that STC or SEPI paid to enter the capital were known, information that the Spanish CNMV would never have required to reveal. But that level of transparency also has a cost, and Telefónica has decided that it is no longer worth paying for.

We already know which country had the highest internet speed in the world in 2025: Spain

by

How has the internet changed in 2025? It’s too broad a question, but if there’s anyone trying to answer it, it’s Cloudflare. The company has published an extensive summary of the most important thing this year and among the numerous conclusions there is one that has surprised us: Spain is the country with the fastest internet connection in the world. Spain at full speed. in the studio stands out that Europe was the clear leader in terms of the best internet connection speeds. Here Spain was also the protagonist, because it was the country with the highest download speed in 2025, with 318 Mbps on average (25 Mbps more than in 2024). It was also the best in terms of upload speed, with 206 Mbps (13 more than in 2024). A possible person responsible. Cloudflare indicates that the reason why Spain leads this unique ranking is probably in the program UNICO-Broadband (Universalization of Digital Infrastructures for Cohesion). This initiative has been going for years and the current goal was to achieve an infrastructure capable of providing services at symmetrical speeds of at least 300 Gbps, scalable to 1 Gbps, and achieving 100% coverage in 2025. Achieving everything is almost impossible —Hello, rural Spain— but that effort certainly seems to be paying off. Spain also more than meets the metric of latency under load: even on intense connections, response times are very good. We also enjoy excellent latency. Data download and upload speeds are important, but so is the latency of the connections: the lower it is, the more fluid the communication is, especially in video conferencing, gaming and streaming applications. Here Iceland takes the cake with only 13 ms, but Spain is still among the best with 19 ms. Things are even better in the so-called latency under load, which measures how long it takes a signal to go and return (the ping) when the internet connection is under intense load (playing online, watching 4K videos). In that metric, much more realistic than “resting” latency, Spain is in third place with 89 ms, a truly remarkable figure. Years as leaders. These results may surprise, but in reality Spain already led these rankings in past editions of Cloudflare’s annual summary. It happened in 2024and also in 2023which is undoubtedly great data that shows that despite the problems that may arise, most users have access to an enviable infrastructure. More traffic than ever. Global internet traffic grew by 19% in 2025, and the person most responsible for that traffic was the Googlebot that searches the internet to index it and make it easier for us to find all types of data in the Google search engine. Although crawlers from AI companies are gaining ground, they are still a long way from Google’s activity, and with good reason: all types of websites want to be “crawlable” in order to be “findable.” The same does not happen with AI. The higher the ratio, the less traffic these chatbots send to content websites. Anthropic is the worst here, and Google, of course, the best by far. What happens to AI in 2025. There are many metrics related to AI this year. For example, Anthropic is the platform that sends the least traffic to content websites (ahead are OpenAI and especially Perplexity). This also causes platform crawling bots (GPTBot, ClaudeBot, PerplexityBot) to be “blocked” in the robots.txt files of many websites to prevent them from collecting data without permission to train their models. Google continues to reign. The list of most popular internet services Not much has changed around the world: Google leads that ranking, and is followed by Facebook, Apple, Microsoft and Instagram. It’s probably more interesting to see what data Cloudflare is reporting on the most popular generative AI services. There the winner is not a surprise (ChatGPT), but the order of the rest of the contenders is striking, because they are then followed by Claude, Perplexity, Gemini and Character.ai. Grok is in ninth place and DeepSeek in tenth, for example. That list will surely be very different in 2026. Image | Sasha Pleshco | Stephen Phillips In Xataka |

James Webb has opened the door to a fascinating world

by

Until not so long ago, the word “exoplanet” seemed more typical of speculation than astronomy. Isaac Newton already dropped in the ‘Scholium Generale‘ of the Principia Mathematica that fixed stars could be the center of systems similar to ours, but science needed centuries to prove it. It was not until the late 1980s that the first signs of planets outside the Solar Systemalthough we had to wait until 1992 to confirm for the first time the existence of worlds beyond the Sun, around the pulsar PSR B1257+12. In recent decades, the pace of discoveries has skyrocketed thanks to increasingly precise instruments, which have allowed us to locate worlds that are as strange as they are fascinating. The Kepler space telescopefor example, identified more than a decade ago Kepler-16ba planet with “two suns” reminiscent of Tatooine from Star Wars. Since then we have cataloged a huge variety of exoplanets, but now the James Webb telescope presents an especially striking find: a world of boiling lava that, to the surprise of astronomers, is colder than theoretical models predict. An extreme world that questions what we know With a radius approximately 1.4 times that of Earth, TOI-561b It is an extreme super-Earth that orbits a star located about 280 light years away, in the constellation Sextans. NASA describes it as the innermost planet of a system made up of four worlds, with an immediate peculiarity: it completes an orbit in less than eleven hours. Its proximity is so extreme, barely 0.01 astronomical units, that the daytime hemisphere must greatly exceed the melting point of rocks. Everything points to a planet trapped by its star in a tidal lock, with eternal day on one side and perpetual night on the other. One of the peculiarities that most puzzles researchers is the low density of TOI-561 b. Astronomer Johanna Teske, lead author of the study, explains that “it is not a super-puff, but it is less dense than one would expect with a composition similar to that of the Earth.” The team envisioned the planet having a small iron core and a mantle made up of less compact minerals, a possibility that would fit the chemistry of its star. As it is a very old G-type star, about 10 billion years old and poor in iron, located in the thick disk of the Milky Way, it is plausible that the planet emerged in a primordial environment different from that of the Solar System. Still, the exotic composition did not resolve all the unknowns, and the team began to consider another possibility: that TOI-561 b was involved through a thick atmosphere. The idea is striking because the models indicate that small planets subjected to such intense irradiation for billions of years should have lost their gases long ago. NASA reminds us, however, that some worlds of this type show signs that they are not simple bare rocks. That nuance opened the door to thinking that the low density could be due, in part, to a volume inflated by a substantial layer of gases. To test the idea of ​​a dense atmosphere, the team turned to a technique that James Webb has used on other rocky worlds: measuring the disappearance of some of the infrared glow as the planet passes behind its star. Using the NIRSpec spectrograph, the researchers estimated the temperature of the illuminated hemisphere and compared it to what would be expected for a surface without heat-distributing gases. If TOI-561 b were a bare rock, its temperature would be around 2,700 ºC. However, observations placed that value close to 1,800°C, a difference too large to ignore. The unexpectedly low temperature makes sense if TOI-561 b is enveloped by a dense, volatile-filled atmosphere. In that case, the winds would transport heat from the illuminated hemisphere to less hot areas, which would reduce the infrared emission received by the telescope. Gases capable of absorbing part of the radiation before it escapes into space also come into play, something that coincides with the models evaluated by the team. YoIt is even possible that silicate clouds exist that reflect the light of the star and contribute to cooling the upper layers of the atmosphere. To explain how TOI-561 b maintains such a resilient atmosphere, the researchers propose a mechanism in which magma and gases are in constant exchange. Tim Lichtenberg points out that as the interior releases volatile compounds into the atmosphere, the ocean of molten rock recaptures some of them, reducing the loss to space. This process requires a planet exceptionally rich in volatile substances, very different from Earth in its initial composition. In Lichtenberg’s words, it would be “like a ball of wet lava,” a description that well sums up the extreme nature of the find. The observations that have allowed us to reconstruct this scenario are part of James Webb’s General Observers 3860 program. For more than 37 hours, the telescope continuously tracked the system as TOI-561 b completed nearly four full orbits, a record that offers a rare glimpse of how its brightness varies along the way. With that volume of data, the team is now analyzing how the temperature changes around the planet and what clues it provides about the composition of its atmosphere. This set of data, still being analyzed, points to a more complex world than was intuited in the first observations. The case of TOI-561 b shows that even the most extreme worlds can hold surprises. Far from just a scorched rock, Webb’s observations describe a dynamic system in which magma, atmosphere, and stellar radiation interact in ways we don’t yet fully understand. As Johanna Teske points out, “What’s really exciting is that this new data set It’s opening even more questions than it’s answering.“The research continues, and each new analysis seems to confirm that this planet belongs to a category that we are only beginning to know.
