The amazing image of the VLT that is already a history of astronomy

by

An international astronomer team has achieved what is equivalent to a cosmic ultrasound: They have obtained the first image of a giant gaseous planet In full formation process, embedded in the middle of a dust and gas disk with multiple rings. The system, called Wispit 2B, has become overnight in the perfect laboratory for Understand how the planets are bornincluding, perhaps, our own Jupiter. A photograph hunted at the best time. The discovery, published in Two simultaneous articles In The Astrophysical Journal Letters, he not only shows us the planet Wispit 2B, a giant of about five times Jupiter’s mass, but has “caught him with his hands in the dough.” They have detected it by emitting the characteristic brightness of overheated hydrogen, the definitive test that is actively attracting material from the disc that surrounds it to continue growing. And if that were not enough, there are indications of an even more massive planet. A cosmic vinyl disk. The first piece of this puzzle is provided by the Sphere instrument of Vary Large Telescope (VLT) in Chile, where the star Wispit 2, a young solar analogue (just five million years old) located about 133 light years from us was observed. What they found was spectacular: an extensive Protoplanetary disc of 380 astronomical units (UA) structured in four concentric rings, such as the grooves of a vinyl disk. The planetary formation theory predicts that the mass planets, when orbiting their star, “clean” their gravitational path, creating gaps on the gas and dust disc. And precisely, in the most prominent hole between the second and third ring, about 57 UA of its star, was a point of light: Wispit 2B. A discovery that had to confirm again. To make sure it was not a distant star in the background, the team made observations in four different moments over almost two years. The results were conclusive: the object moved next to the star, following a Keplerian orbit consisting of his position in the hole of the disc. The analysis of its brightness in different infrared wavelengths (Bands H and Ks) allowed to estimate its mass by approximately 4.9 times Jupiter’s mass. This is the first unequivocal detection of a planet on an album with multiple rings, directly confirming the interaction between the planet and the disc that forms it. A second definitive test. If the first investigation was the photo of the crime, The secondled by Laird M. Close, is the recorded video confession. Using the advanced Magao-X adaptive optical system in the Magallanes telescope, they also observed the system in a very specific wavelength: that of the H-Alpha (656.3 nm). This broadcast is an unmistakable firm of the accrection, the process by which a planet attracts gas from its surroundings. When hydrogen gas falls to the planet, it is compressed and heated to thousands of degrees, emitting a characteristic reddish glow. And WISPT 2B was shining intensely in H-Alfa. We already know its growth rate. This detection not only confirms undoubtedly that Wispit 2B is a growing protoplanet, but allowed the team to calculate at what rhythm it is collecting matter: 2.25 × 10−12 solar masses per year. It is a slow but constant rhythm, which offers us a unique window to the final stages of the formation of a gas giant. This finding makes Wispit 2B one of the very few protopoplanets (along with the celebrities PDS 70b yc) of which there is direct evidence of accretion, that is, that they grow gradually using external matter. A second planet and a mystery of inclination. The surprises do not end there. The high resolution data of the Magao-X team revealed a second candidate object much closer to the star, about 15 UA. Baptized as CC1 (Close Companion 1), this object is extremely red and its brightness is consistent with a planet about nine times Jupiter’s mass. In addition, researchers have indicated a curious statistical coincidence. Counting to Wispit 2B, there are already four systems with protoplanets detected by their H-Alpha broadcast. Surprisingly, they all have a very similar inclination with respect to our line of vision (between 37 ° and 52 °). The probability that this occurs by chance is only 1% (a 2.6σ significance). Why is Wispit 2B so important. There are several reasons behind. The first of these is that it visually demonstrates that giant giant planets can be formed at great distances from their star and that they are responsible for sculpting the holes in protoplanetary discs. But the interesting thing is that it has become a unique laboratory, since it is such a “clean” and well-defined system, it allows us to study the planet-Disco interaction with an unprecedented detail. An analogue of our past: The star is similar to our sun in his childhood, so studying Wispit 2 is like looking at a snapshot of how our own solar system could have formed. That is why the next step will be to point to Wispit 2B with the Jame Webb space telescope and the Alma Observatory. With them, you can analyze the planet’s atmosphere and analyze the chemical secrets you can hide.

Chatgpt’s mobile app generates 30 times more money than Claude, Copilot and Grok together. Still not enough

by

If there is a chatbot that stands out in popularity over the rest, that is undoubtedly chatgpt. His mobile app was launched in May 2023 And since then he has occupied the download tops of the main stores, becoming The most downloaded app in the world A few months ago. Openai has reached another milestone with its app: since its launch already has generated 2,000 million dollars. To put it in context, this would be approximately 30 times more than what Claude, Grok and Copilot combined have generated. However, not everything is as beautiful as it sounds. Undisputed leader. According to figures AppfiguresOnly for 2025, the Chatgpt app has generated 1,350 million dollars, which represents a growth of 673% compared to the same period of 2024. Chatgpt is generating 193 million dollars per month, while the next on the list is Grok with 3.6 million per month. If we look at the average download per expense, ChatgPT goes to the head with 2.91 dollars, followed by Claude with $ 2.55, Grok with $ 0.75 and finally co -pilot with only $ 0.28. It is clear: Openai is winning the battle of mobile apps. Still not enough. 2,000 million are many millions and that only with its mobile app. Adding all your services, only In July 1,000 million entered And it is estimated that they will enter 12,000 million this year. However, It is still light years of being profitable And the reality is that they enter much less than they spend. The company did An internal study in which they estimated that the losses between 2023 and 2028 would amount to 44,000 million dollars. According to their forecasts, they will not be profitable until 2029, when they expect to enter 100,000 million dollars annually, almost ten times more than they invoice now. The Big Tech are on the right track. The great technology have invested amounts of authentic madness in AI And it has not been until recently that they have begun to see A slight green outbreak in its results. After several years burning huge amounts of money, Google, Amazon and Microsoft have seen how their income is finally to cover the investment so tremendous. However, it is still not thanks to the products AI directly, but to the cloud services. Even so, the reality is that None is making gold with AI. Mission: Monetize the AI. If there is something that brings to the business of AI is How to monetize your chatbots. Subscriptions “pro” have become the appeal to get income, Some like Claude Max cost a real fortune and OpenAi He followed his steps with O3 Pro. The Subscriptions are getting more expensivebut they are not yet enough to reach the level of expenses. There is no azure or a web service that can get the chestnuts out of the fire as it is happening with the Big Tech. The exit seems clear. Advertising. At the end of last year there were rumors that they could start putting advertising in Chatgpt. At the moment it has not materialized, but Rumors have not ceased and seeing the numbers may be a solution to the profitability problem. They have not been the only ones who have flirted with this idea, Perplexity was also testing it And Elon Musk recently confirmed that There will be advertising in Grok. Very careful. Implement advertising in a chatbot is delicate since we could find ourselves in a scenario in which it ends up losing the trust of users. For example, if we go to a chatbot in the process of buying a car, we could doubt whether the recommendations are based on an advertising campaign. Integration should be clear to avoid possible confusing situations. What seems clear is that, given the serious problem of profitability, advertising stands as a more than attractive option for AI companies.

of the second -hand market

by

The US government has been doing everything that is in their hand to prevent Chinese companies and research organizations for more than three years artificial intelligence (AI) more advanced that produce nvidia, AMD or brainsamong other companies. This is the purpose of Export restrictions Of these GPUs approved by the Department of Commerce, which in this area is the executing arm of the administration. Despite the efforts of the US government, the avant -garde chips for AI They have continued arriving in Chinaalthough it is reasonable to accept that in amounts lower than those needed by companies that are dedicated to the development of large AI models. And they have done it mainly through secondary markets and parallel import roads that run in India, Malaysia or Singapore, in which The US action It is very limited. Nvidia has achieved the export license you need to sell in China Your GPU for IA H20but the Chinese government has vetoed this chip. And he has done so that the administration of the cyberspace of China, which is the main Internet regulatory body in this country, This GPU is thoroughly investigating Because he suspects that he could incorporate a rear door of difficult location by Chinese experts. If so, the possibility of China to use this chip. China is getting in the second -hand market the best Nvidia GPU China already has Three very clear alternatives to Nvidia. Cambricon Technologies, Huawei and Moore Threads are the three Chinese chip designers for ia who are better positioned to get the market that NVIDIA maintains in China. Despite all the developers of great AI models that have projects with projects with CUDA They need chips from this last company. And, according to Digitimes Asiathey have found the appropriate place to get these GPU: the international second -hand market. However, the most interesting thing is that they are not being formed with the H20 chips that, as we have seen, have been prohibited by the Chinese government; They are getting the GPUs H100 and A100 of Nvidia, which They are more powerful than H20. For the US it is essentially impossible launch an unpublished strategy. This measure will consist, if it finally comes to fruition, to introduce the technology necessary to allow them to be tracked at all times. Chinese companies are buying huge games of NVIDIA A100 and H100 in the second -hand market A priori would be a form of geolocation that would identify where each integrated circuit resides during its journey once it leaves the semiconductor factory. Michael Kratsios, the director of the Office of Scientific and Technological Policy of the White House and one of those responsible for the US government’s action plan for the development of AI, has confirmed that are considering the possibility of introducing tracking solutions both implemented in the hardware and software itself: “We are discussing what software or physical changes could be introduced into the chips themselves to improve the tracking of their location.” The US administration is determined to protect its current leadership in the development of hardware for AI as the adoption of this technology accelerates throughout the planet. However, implement the solution proposed by Kratsios and other White House advisors It implies important technical challenges. Constant tracking by GPS is not practical in this scenario of use, According to Kratsios himselfso a possible solution is to introduce in each chip the logic necessary to confirm its location periodically. In this way, external networks can be reduced. The problem is that this design increases the complexity of the logic of each chip and can presumably impact its performance, which would penalize its productivity in the calculation centers. In addition, the cost of each GPU will increase and hackers They could find new ways to violate the safety of these chips by resorting to possible weaknesses of tracking logic.

One million less places this winter at provincial airports

by

The pulse between the government and Ryanair continues to climb. After a summer in which the company had withdrawn 800,000 places from our country, it now ensures that it will withdraw a million seats available this winter. The official reason: Aena’s rates. THE OFFICIAL: THE FINE OF CONSUMPTION TO THE COMPANY. One million less. That is what Eddie Wilson, CEO of the airline, has confirmed to Europa Press. The company will eliminate a million places available during the next winter season. The definitive announcement should occur Next Wednesday, September 3. In his interview, Wilson says that the movement is because they will “invest where we can obtain a return” since, in his opinion, the government is allowing regional infrastructure “to deteriorate and underminate.” Because? The official reason that Ryanair wields is the increase in the airport rates charged by Aena. The company, which manages these spaces and provides services such as safety, cleaning and other logistics -related activities, will raise prices next March. The company wants the new rate increases by 6.5% With a maximum of 11.03 euros per passenger after the price has almost frozen a decade. This only increased (although by 4.09%) in 2024 alleging that the Ukraine War had hit its accounts. At the moment, competition has to confirm whether this increase in rates may or may not be carried out. And, despite everything, it is something that will be applied from next March but Ryanair has already repeatedly threatened With the reduction of the offer if this happened. What does Aena say? The company ensures that not all sites pay the same for the service they offer and have stressed on several occasions that their work is essential for the operation of the airport itself. Payment at Aena’s rates includesamong other services: Aena’s staff Air navigation services (such as communications or meteorological reports) Security services MAINTENANCE AND CLEANING SERVICES Attention to people with reduced mobility In addition, the company indicates that they exist Incentives so that airlines pay less where airports accumulate less offer. For example, the discount in the passenger rate with reduced mobility is 100%. In regional airports that have not recovered prepandymia traffic, the discount is 70%. And there are additional discounts for passengers who make connections or fly to the Canary Islands and Balearic Islands. There is something else. It is not only a matter of rates. Ryanair and the government also maintain a war open for the issue of hand luggage. Consumption fined the company (109 million euros)along with other airlines, because it considers that the size of the suitcase that you can transport for free is excessively small. Europe, however, seems to give the reason to the company. At the moment, the litigation continues. Last June 26, The Superior Court of Justice of Madrid suspended in a precautionary way it and from Ryanair say they have “absolute confidence that The mules will be canceled“For European justice. There is no confirmation of the latter but the truth is that The European Parliament and The European Commissionon their way to reform the regulations that affect travelers, they seem to align with Ryanair. If everything goes ahead, they should define some Minimum dimensions for this backpack/suitcase But these are aligned with those offered by the Irish company that also He has already made his own gesture of goodwill. Those indicated. Regional airports will be those that undergo the changes in Ryanair’s strategy. During the summer season we are living, the company It has already eliminated 800,000 seats from seven airports. In Jerez de la Frontera and Valladolid they have stopped operating. In Vigo, Santander, Santiago and Zaragoza and Asturias have reduced their operations to a greater or lesser extent. This frightened has directly impacted the number of flights made in these airfields. Between April and July (first four months of the summer season) they traveled 240,000 passengers less that in the same period of 2024. It remains to be seen the impact at the end of the summer season but airports such as Valladolid anda have been practically deserted.

The body warns of Alzheimer’s long before the brain. The track is in the intestine

by

Keep ‘healthy’ The bacteria we have in the intestine It is more important than we can think. During the last decade there are many voices that have arisen pointing to the relationship between our microbiota and other parts of our body. Now, a study has given light on the amazing connection that exists between digestive and metabolic health and the risk of developing diseases neurodegenerative as Alzheimer’s either Parkinson. A study that has used data of all kinds. Research, published in Science Advances, Not only identifies specific disorders that increase the risk of these diseases, but also demonstrates that these signals can be detected up to 15 years before neurological diagnosis, opening a new and promising via for Early detection and prevention. The work, which analyzed the clinical, genetic and proteomic data of hundreds of thousands of biobancos such as the UK Biobank, Finngen and Sail, is the most extensive of its kind and reinforces the importance of called intestine-corebro axisthe complex communication network that connects our digestive system with the central nervous. Digestive disorders and Alzheimer’s. The researchers analyzed the association of 155 digestive, endocrine, metabolic and nutritional disorders with the future risk of Alzheimer and Parkinson. The results are revealing. For Alzheimer’s, it was found that previous diagnoses of the following conditions significantly increased the risk: Gastritis and duodenitis Esophageal reflux disease (esophagitis) Diabetes (all types) Vitamin D deficiency Electrolyte disorders and acid-base balance Functional intestinal disorders (such as irritable intestine syndrome) There are also warning signs for Parkinson. A disease that is also neurodegenerative and is iconicly characterized with a constant tremor, among many other signs. In this case, the pathologies that could be an alert sign to generate this disease were: Dyspepsia (indigestion) Diabetes (dependent and independent of insulin) Functional intestinal disorders The importance of being a stratified study. This means that the data were divided into windows from 1 to 5, 5 to 10 and 10 to 15 years before diagnosis. This is something really important, since researchers could confirm the theory that the increase in risk is not something that happens just after the appearance of the first neurological symptoms, but it is a process that is created over more than a decade. For example, a diagnosis of non -insulin -dependent diabetes between 10 and 15 years before was associated with a 71% greater risk of developing Alzheimer’s. The importance of an early diagnosis. And it is that diagnosing a neurodegenerative disease so in advance is the best asset we have to avoid its most unwanted effects. Right now Alzheimer is an incurable disease, but There are drugs that stop the disease. From here lies the importance of having an early diagnosis, since the sooner the timely treatment begins, the more difficult it will be to progress to the worst stages. It also has protection functions. Curiously, it has been seen that a hemorrhoid diagnosis was associated with a lower risk of Alzheimer’s. The authors speculate that this could be due to a survival bias: the serious conditions that are sometimes associated with hemorrhoids could have a higher mortality rate, which would reduce the probability that these patients live enough to be diagnosed with Alzheimer’s. Genetics or lifestyle? One of the most counterintuitive findings in the study has to do with genetics. The researchers calculated the polygenic risk scores (PRS), which is a measure of genetic predisposition to a disease, and compared them. They discovered that patients who developed Alzheimer’s or Parkinson and also had one of these digestive or metabolic disorders, on average, had a lower genetic risk score than those who developed the neurological disease in isolation. Inheritance does not matter so much. These results can translate into that the person with intestinal comorbidity, environmental and lifestyle factors They play a much more decisive role in the development of Alzheimer’s or Parkinson’s than the genetic inheritance itself. It is the evidence that we needed to reinforce the idea that the disease is not only in our genetic material, but that the environment and our decisions can intervene in its development. Towards a multimodal predictive model. The true qualitative leap of the study is the creation of a multimodal prediction model. Instead of based on a single type of data, scientists combined four pillars of information: clinical, genetic, proteomic data (with the analysis of 1,463 biomarkers) and demographic. The result was a model with a predictive capacity much higher than that of any individual paradigm. For Alzheimer’s, the combined model reached a 0.90 precision (AUC), a very high level for this type of predictions. It is interesting to note that the model that excluded clinical data, but maintained genetics, proteomics and demography, obtained almost identical precision (0.89), which suggests that blood biomarkers already capture much of the biological information that underlies clinical diagnoses. A diagnosis based on an analytical. Among the most influential biomarkers were found GLIAL FIBRARRARARY ACID PREIIN (GFAP) and the light chain neurofilament (NFL), both known as indicators of neuronal damage, which validates the biological robustness of the model. This approach demonstrates that the integration of different “omics” (genomic, proteomic) with clinical data is the way to follow for truly early and personalized detection, long before cognitive symptoms or irreversible motors appear. The team has even developed an interactive web platform so that other researchers can explore the results, promoting transparency and reproducibility.

In Galicia the orcs are hitting sailboats. And there is an unexpected reason why they are there: the octopus

by

In Galicia, at least in part of the Galicia Litoral, summers begin to be marked by something more than the escapes to the beach, the pilgrims, the arrival of Fodechinchos tourists and (unfortunately) forest fires. On its coasts They usually sneak spontaneous ones that attract more and more looks, both for their spectacular and ‘encounters’ that occasionally leave with the small boats that navigate near the estuaries: the orcs. The summer of 2025 is not an exception. And for now he has already left some discovery amazing. What happened? That in recent days the Galician coast has had peculiar protagonists: orcs. It is nothing new. A few years ago We talked to you Already of their incursions in part of the coast of Spain and Portugal and how sometimes they leave the occasional scare when they run into sailboats or small boats. That does not mean that your presence continues to generate expectation, both among the media (even The Times has echoed of sightings) as among the authorities. In fact they have already forced to mobilize Maritime rescue and the Civil Guard. Where did they see? The Atlantic Orca Working Group (GTOA) includes a tool on-line which allows to follow the latest interactions between ships and orcs. His map shows sightings in the surroundings of the Gulf of Cádiz, the Portuguese coast, part of the Cantabrian and especially on the Galician coast. On Saturday Maritime Rescue confirmed the existence of three different groups in the Galician Atlantic Strip and The regional press has confirmed the presence of specimens in The Baixas Ríasalthough Gtoa has also registered interactions further north. Why is it news? For several reasons. The main one, its ‘encounters’ with sailboats. On Saturday maritime rescue already asked the navigators of the region that extreme surveillance on the Galician Atlantic coast and warned that a sailboat had to be towed to the port and another escorted precisely by the presence of orcs. The Pontevedra Civil Account too He spoke A week ago in X of incidents In Costa da Vela, north of the Cíes Islands, with several sailboats involved, and how one of them ended with damage to the helm shovel. Europa Press assures that as a precaution a regatta and maritime rescue was suspended in charge of these days of remember To the navigators a series of basic guidelines in case of these animals, such as not approaching the bands of the boat or navigating to the coast in search of shallow waters. The normal thing is that the incidents (when there are) do not go beyond blows wave loss of the helm, although there are cases of sailboats that They have ended up anxiety. But … why do they act like this? The phenomenon It is not exclusive of Galicia and has given rise to multiple theories that explain the behavior of these cetaceans. Some point to food scarcity, the possibility that ORCAS consider vessels as competition or even an unexpected effect of pandemic and the break of nautical activities, resumed in recent years. Last year a working group of the International Whaling Commission He raised An explanation Much simpler … and curious: the orcas that ram ships are mostly specimens Young and boring They do it as a game, a fun that would not seek to cause intentional damage to the sailboats or the crews that are on board. “It is more playful than intentional,” summarize Alex Cerbino, from the CBI. If true could be a “temporary” behavior, as already Others have been seen. What exactly do Galicia? That is the other surprise they have left this summer in Galicia. Experts have long known that these animals move chasing the Atlantic red tuna, their favorite delicacy. In fact, the search for food is what explains summer migrations from the Strait of Gibraltar to the north, which in autumn look for deep waters and already in winter return to the narrow area, where they remain until spring, Remember Gtoawhich clarifies in any case that migrations of the Iberian orcs can be “diffuse” and it is not strange that they do not travel in block. Now experts have found out more than helps to understand the incursions of these cetaceans in the Galician estuaries. A recent investigation of the Institute for the Study of Mulas Vigo lighthouse either The voice of Galicia He has concluded that the Iberian Orcs arrive in Rías such as Aruouso in search of something more than atlantic red tuna. They also do it to capture other of their stars dishes, cephalopods. What are you looking for? The same as many Galicians and tourists in summer: in addition to squid, the great food of the gray calderones, the orcs look for a good ration of octopus. “They love it!” assures to Lighthouse Bruno Díaz López, director of the BDRI and Doctor of Ecology. “Thanks to the sightings made in recent years and during the weekend in the Ría de Aruous we have resolved a recurring enigma: the orcs penetrate the estuaries to feed on octopus.” Experts have appreciated “series of long and repeated vertical dives, direction changes, controlled promotions and brief ventilation pauses” that, in their opinion, correspond to the hunting methods used by the cephalopod predators. BDRI experts have even seen Orcas pull nasas for octopuses. In case there were doubts, they have also managed to “visually document specimens emerging with octopus in the mouth.” “This finding explains the repeated entrance of Orcas in the Ría de Arousa in the last three years,” they claim. Is it important? Yes. Although the orcs go behind the tuna, the finding gives us new information about their incursions in Galicia. “Beyond their main prey in the open sea, the orcs take advantage of coastal trophic opportunities linked to octopus in specific periods,” concludes The director of the BDRI, who remembers that the phenomenon does not fit only with the most recent observations, but also with the documentary records. “It agrees with historical testimonies of Aguiño … Read more

Nvidia has become hostage of her own success. His record numbers know little when the world expects miracles

by

Nvidia has presented her Results of the second fiscal quarter. Technically beat all forecasts: Adjusted benefits of $ 1.05 per share compared to the 1.01 expected. Revenues of 46,740 million dollars against the projected 46,230 million. The company has also projected income of 54,000 million for the current quarter, slightly above the consensus of 53.4 billion. Why is it important. These seemingly solid numbers have not been enough for a market that has turned Nvidia into the fire test definitive of boom of the AI. The action has fallen 3% in the operations after closing, a reaction that reveals to what extent the expectations about the most valuable company in the world – with 4.4 billion capitalization – have reached almost impossible levels of satisfying. China’s problem. The great shadow on the results has been the total absence of sales of the H20 chip To China during the quarter. Nvidia has not included any sales forecast to China in its guide for the third quarter, despite the fact that the financial director, Colette Kress, has mentioned that they have between 2,000 and 5,000 million dollars in ready -to -send orders to send if geopolitical issues are resolved. The company is waiting for the Trump administration to clarify the regulations on the 15% cut they want to impose to Chips sales to China. Jensen Huang has been unusually direct during the Call with analysts: “The Chinese market estimates that represents about 50,000 million dollars of opportunity for us this year.” He added that half of the world’s researchers are in China … And that it is “quite important” that American technology companies can access that market. Between the lines. Huang’s frustration with the geopolitical situation is palpable. His comment that “we just have to continue advocating” before the Trump administration makes us glimpse a more tense negotiation than the official statements say. The CEO has suggested that they are working in a modified version of their Blackwell chips for China, with reduced performance, indicating that Nvidia is willing to make weight concessions so as not to lose that market. Striking in a company Today as powerful as Nvidia. Data centers disappoint. The data centers segment, which represents 88% of total income, has generated 41,1 billion dollars, slightly below the expected 41,290 million. It is the second consecutive trimester that this important segment does not reach expectations, a worrying signal when large technological ones such as goal, Google and Microsoft are investing tens of billions each quarter in AI infrastructure. “Everything is sold”. Huang has said during the call that “everything is sold”, referring so much to the Hopper chips current as the new Blackwell. Has added that the production of Blackwell Ultra It is “progressing at full speed” and that demand is “extraordinary.” However, these statements contrast with the fact that the income growth of 56% year -on -year is the slowest in nine consecutive quarters of growth greater than 50%. Growing pressure. The market reaction tells an uncomfortable truth: Nvidia has become hostage of its own success. With a weight of 7.5% in the S&P 500 – 3% in December -, Any stumbling block has the potential to drag the entire market. An important Nvidia failure would be a detonation for half -world bags. The contrast. Huang has promised that AI infrastructure spending will reach between 3 and 4 billion dollars for the end of the decade, but the immediate reality is that NVIDIA cannot freely access the second largest computer market in the world. The repurchase of 60,000 million dollars in shares approved by the Council – one of the largest in American business history – seems more an attempt to sustain the price of the action than a real confidence signal in the future without regulatory mosquadillas.

41,000 years ago, our ancestors survived an investment of the poles. We already know how they cope with this change

by

About 41,000 ago, planet Earth became a much more hostile place than it is now. He magnetic shield that protects us from solar wind and Cosmic radiation It weakened until almost disappearing, and the magnetic poles, those references that the compasses use, abandoned the Arctic and Antarctica to roam all the globe. This event, known as the Laschamp excursionhe plunged the planet into An unprecedented radiation environment for almost two millennia. Our ancestors lived differently. The Homo sapiens I know They expanded by Eurasiaand the Neanderthals In their last millennia of existence, they lived under a very different sky. A new and revolutionary study published in Science Advances The space environment of the Earth has first rebuilt in 3D During this chaotic period. The results not only show us what the planet was like, but they offer fascinating clues about how our ancestors could have survived and even prospered. A broken magnetic shield and auroras about Ecuador. The Earth’s magnetic field is like an invisible shield generated by the planet’s liquid iron core. It protects us from a constant flow of charged particles emanating from the Sun. without it, The atmosphere would be swept and life on the surface, bombarded by harmful radiation. During the Laschamps event, This shield weakened until it reached just 10% of its current force. According to the simulation of the team led by Agnit Mukhopadhyay, this had two spectacular consequences related to the magnetosphere and the poles. The magnetosphere contracted dramatically. The protective bubble that surrounds us shrunk almost half of its normal size. At its weakest point, the limit of this shield (the Magnetopause) was only 15,500 km from the surface, a dangerously close distance. The poles went crazy. He Magnetic axis More than 75 degrees leaned. This caused the Earth’s magnetic field to become “multipolar”, with several North and South weak poles distributed by the planet, a configuration More similar to Uranus or Neptune than to that of our current land. Logically they had consequences. The most visible consequence of this magnetic chaos was the migration of the auroras. Normally confined to the polar regions, the lights of the north and the south expanded and wandered throughout the globe. The simulation shows that the Auroral oval moved from the Arctic, passing through Western Eurasia, until it reaches northern Africa. At the same time, in the southern hemisphere Las Auroras moved over Australia and New Zealand. In the peak of the event, the auroras were probably a global phenomenon, visible from almost any point on the planet. Adapt or die. See auroras From the Sahara it may sound poetic, but the reality was much more bleak. Those lights meant that the “open field lines” were no longer only on the uninhabited poles. They covered regions densely populated by prehistoric humans such as Europe. This implied a much greater exposure to Ultraviolet radiationwith all its associated hazards such as burns, skin cancer, eye damage or even fetal development problems. This is where the study connects geophysics with archeology in a fascinating way. The researchers point out that the Laschamps event coincides with notable changes in human behavior, which could be interpreted as adaptations to this new and radiant world. Appearance of custom clothing. The Homo sapiens From the Auriñaciense culture they developed tools such as bone needles and scrapers, associated with the manufacture of tight clothing. This clothes, unlike the simple skins or layers that are believed to use the Neanderthals, offered a Much more complete protection against UV radiation without sacrificing mobility. This innovation could have conferred on sapiens A competitive crucial advantage. Generalized ocher use. The ocher, a mineral pigment of iron oxide, becomes much more common in the archaeological sites of this era. It is known that ocher is an effective topical sunscreen. Its extended use could have been a direct response to protect the skin. The Boom of Rock Art. The event also coincides with the appearance of some of the first cave paintings known figuratives. The hypothesis is that, to protect themselves from radiation, humans spent much longer within caves, which could have encouraged the development of this cultural and symbolic expression in the safety of the gloom. The inevitable: the disappearance of the Neanderthals. This fact occurred just at the end of this period and that is why it was almost safely A multifactorial process. However, this study suggests that its possible inability to adapt to high levels of radiation, in contrast to the cultural innovations of the Homo sapiensit could have been another factor in its decline. If it occurred today, it would end up in Apocalypse. Although a geomagnetic event like Laschamps is not imminent, the Earth’s magnetic field It has weakened around 10% in the last 180 years and The magnetic north pole is moving at a record speed. If a similar event occurred in our current society, we would face an apocalypse. A weakened magnetic shield would leave our completely exposed communications and GPS satellites. The global electricity would suffer massive overloads that would cause generalized and lasting blackouts. And all this would be added to an alteration in the atmosphere that could lead to very important climatic changes. A look at the future of our planet. The Laschamp excursion study is not just a window to our deep past. It is a warning about the fragility of our world and a reminder that Earth is a dynamic and sometimes violent system. 41,000 years ago, our ancestors survived thanks to their ingenuity. Today, our survival would depend on a technology that, ironically, would be the first to fall.

The future of the European cloud is being written in Aragon. AWS has made him his most ambitious bastion in Spain

by

What until now was an ambitious announcement has just become a reality. The Aragon government has published in its official bulletin the approval of the General Plan of Interest of Aragon (Piga) that will allow Amazon Web Services (AWS) expand your infrastructure in the region. This is a project presented in May last year that contemplates an investment of 15.7 billion euros and that comes with the promise of promoting thousands of jobs, both direct and indirect. The process has been resolved in just 15 months, an unusually brief period for these types of procedures, and that places the American multinational in a position to immediately start the works in the municipalities where it already has a presence and in others in which it will be installed for the first time. We do not talk about a starting point, but of an extension: Amazon already operates three centers in Aragon And now he plans to lift five more. The Aragonese bet to become a strategic cloud enclave The key that this advance has promoted is in the Pigawhich acts as a fast route for large -draft initiatives. The regional government declared AWS’s expansion in 2024 INVESTMENT OF AUTONOMIC AND GENERAL INTERESTwhich opened the door to a preferential process. In the social network XThe Executive highlighted the publication in the BOA and the words of the counselor Octavio López, who valued the fifteen months that the entire process lasted. Click on the image to see the original publication in x As we indicated above, the planned investment amounts to 15.7 billion euros. It is the greatest technological operation approved in Aragon and one of the most ambitious in Spain. The regional government emphasizes that this figure reflects not only the size of the works, but also Amazon’s commitment to consolidate its presence in the region. The execution, of course, will be progressive, with an estimated temporary horizon of ten years. The plan contemplates a remarkable scale jump: of the three existing campuses It will be passed to a total of eight locations in Aragon. These will be located in Villanueva de Gállego, Huesca, Ebro Burgo, Zaragoza-La Cartuja and Sotonera. Each campus will integrate not only data centers, but also auxiliary facilities necessary for its operation. The plan foresees new access roads, fiber optic and High voltage lines for campus. In water matters, specific conduits for process water and evacuation networks will be enabled. Data centers are the machinery that supports digital life. There photos, videos and documents are stored, processes that work the social networks are executed and transactions that move the economy are managed. Every time you see a series in streaming, you participate in a video call or make an online payment, there are servers by processing the information in the background. Companies such as Google, Microsoft or Amazon operate this type of infrastructure. In Aragon, the extension corresponds to AWS. All the site planned in Aragon will be interconnected by fiber optics and managed as a single unit. In the company’s jargon it is called the AWS region, in this case identified as AWS Europe (Spain). The model is based on dividing the region into several areas of availability, so if one suffers an incidence, the others maintain the service. The extension ensures more capacity, lower latency and greater resilience for customers who use services in the Peninsula. Official documents stand out that campus will be equipped with redundant energy, cooling and communications systems. This means that, although a component fails, the service remains active. Fire detection measures, water leak control and operational continuity protocols are also included. In parallel, the plan incorporates energy efficiency and water management commitments, with infrastructure designed to optimize consumption. The goal is to sustain growth that combines technological capacity and environmental sustainability. Not everything is lights along the way. As the country collectedAt the end of 2024 Amazon requested to expand in a 48% water availability for its three complexes already active in Aragon. The petition ignited the alarms of groups as environmental environment and your platform your cloud dry my river, which question the water impact of this type of facilities. In their allegations they recalled that climate change should already have been considered and that, in full structural drought, what corresponds is to limit consumption. The Aragon government presents this extension as part of its strategy to attract technological investment and reinforce the role of the community on the European digital map. In the official communication it is noted that projects of this scale allow diversifying the economy and modernizing key infrastructure. Beyond the numbers, the institutional message aims to consolidate Aragon as a cloud reference enclave.
