The change of Google’s search engine with AI was a mystery about its monetization. Finally it will be another subscription

by

For months, the technology industry has been closely watching how Google resolves its particular dilemma: how to integrate artificial intelligence into its search engine without destroying the advertising business that supports its empire. The doubts are being cleared up little by little, and everything indicates that the company has already solved it: through AI Plusa subscription with a cost of 7.99 euros per month. Dilemma. The results of traditional search with blue links They generate billions in advertising, being one of the company’s most lucrative businesses and also one of the reasons why it is where it is. On the other side we have his foray into the AI ​​careera business in which they are burning money on infrastructure in the hope that it will be profitable in the long term. This last business also clashes with the traditional advertising system, with which Google also takes great advantage. Embracing the new potentially means burying what feeds you. The company is looking for a solution to this dilemma with Google AI Plus. What does the 8 euro subscription include? AI Plus has recently reached 35 new countriesamong them Spain. For €7.99 per month, users get enhanced access to Gemini 3 Prothe image generator Nano Banana Prothe research tool Deep Research200 GB of cloud storage and the possibility of using Gemini directly in Gmail, Docs, and other Google apps. Also includes 200 monthly credits for flow and Whiskthe company’s AI video creation platforms. Duel with OpenAI. The price is tight and even lower than the offer. ChatGPT Gowhich is found in Spain at a price of 9.99 euros per month. Both companies are fighting to attract users who want more than the free version, an opportunity to obtain more financing for their AI operations and, over time, attract even more customers who want to immerse themselves in more complete and higher-cost plans. Limitations to justify the price. The version of Gemini 3 Pro included in AI Plus has significant restrictions compared to the AI ​​Pro subscription of 22 euros per month. For example, the context window is drastically reduced from 1 million tokens to 128,000, which means that the model will “forget” information much sooner in long conversations or when analyzing long documents. Monthly credits for creation tools are also five times lower: 200 versus 1,000 in the Pro version. Google gives away AI to its storage customers. The company is adding all AI Plus features automatically to existing subscribers of Google One Premium (2 TB for 9.99 euros per month) at no additional cost. This avoids the absurd situation where paying more would result in having fewer features, but it also shows Google’s commitment to getting its users who pay for storage familiar with Gemini without them having to think twice. A change for the media. Google is building a monetization strategy around AI, and that affects the media. In this way, the media goes from being the user’s final destination to becoming data providers to train and feed AI responses. When Gemini responds directly instead of displaying blue links, traffic to the original sites evaporates, along with the advertising revenue they generated. The issue is somewhat tricky and it is still unknown how all the parties involved are going to agree. Subscriptions. Google is betting on a freemium model that allows it to make its investment in AI profitable without completely abandoning its traditional advertising business. The question is whether users will be willing to pay for something that until now they considered free. Unlike Netflix or Spotify, AI subscriptions They are still a relatively new concept to the general public. We will have to wait to find out if this tightrope walk balancing exercise by Google ends up convincing in the long term. In Xataka | The number of new apps coming to the App Store has skyrocketed.

How a mummified wolf has solved the mystery of the woolly rhino’s extinction

by

14,400 years ago, a barely nine-week-old wolf cub feasted on the Siberian stage. Shortly after gobbling that piece of meat, the puppy died and was buried in the permafrostnear the village of Tumat in northeastern Siberia. Something that at first seems insignificant, has given one of the most important milestones in modern paleogenetics. And this one was in this puppy’s stomach. The study. A team of scientists from the Center for Paleogenetics at Stockholm University has achieved what seemed impossible: Recover the complete high-coverage genome of a woolly rhinoceros (Coelodonta antiquitatis) from the undigested remains in that wolf’s stomach. The results, published in Genome Biology and Evolutionforce us to rewrite the books on how and why this megafauna became extinct, since until now we had a very different idea. A biological miracle. The discovery of this puppy is not something recent, since it was found in 2011, and received the nickname Tumat-1. Being mummified in ice, the reality is that it was in perfect condition, but during the autopsy the researchers found a 3-centimeter piece of tissue with remains of blonde fur. Due to the area in which it was initially found, it was thought that it was a cave lion. But the reality is that genetics has said something very different: it was a woolly rhinoceros. Something that is incredible, since it is the first time in history that the complete genome of an Ice Age animal has been sequenced from the stomach contents of another animal. A great milestone. For science to recover the genetic material of a species in these conditions, the truth is that it is something incredible because of the doors it opens. And DNA is where we can find practically everythingeven the genetic health of the species before its end. Genetic decline. For decades, the dominant theory suggested that woolly rhinos disappeared due to slow genetic erosion. It was believed that, as its population was reduced, inbreeding accumulated harmful mutations that doomed the species due to the many diseases caused by having children between relatives. But this is something that has now been completely debunked. When comparing the genome with samples from 18,000 and 48,500 years ago, the researchers found no decline in diversity. Furthermore, there was no indication that the species was in a state of inbreeding as there was no genetic crossing between close relatives. That is why the effective population remained stable at about 1,600 individuals until just a few centuries before its total disappearance. The culprit. If it was not genetics and inbreeding that condemned the species and not human hunting (because thousands of years passed together without it happening)… what happened? Science now points to Bølling-Allerød Interstadial, a period of abrupt climate warming that occurred about 14,000 years ago. This phenomenon transformed the dry, cold steppe (the rhino paradise) into a landscape of bushy vegetation and, most critically, deep snow. Without being able to live. The woolly rhino, with its short legs and heavy body, was not designed to walk on soft snow or dig for grass under thick layers for food. In this way, it was an environmental trap that caused the animals to not be able to adapt correctly to the new habitat that had been generated around them due to how quickly it happened. Looking to the future. What we learn in the past can also be applied today and tomorrow. And this study does not only speak of the past, since in a context of current climate crisis, the case of the woolly rhinoceros is a warning. It shows that even a species with a stable population and robust genetics can collapse almost instantly if the ecosystem changes abruptly.

In 1845, John Franklin’s expedition set sail in search of the Northwest Passage. 180 years later his loss remains a mystery

by

On the morning of May 19, 1845, Captain John Franklin and his expedition weighed anchor from the Greenhithe Harboralmost at the mouth of the Thames. They were looking for the Northwest Passagethe (at that time theoretical) maritime route that would link the Atlantic and the Pacific through northern Canada. They never came home. 129 men who never returned and who, for 170 years, have been one of the great questions of scientific and naval exploration. We now know why the men of John Franklin’s lost exploration died. There are those who insinuate that the trip started badly from the beginning. It should never have been in the first place. John Franklin. The first option William Edward Parryone of the great English explorers, but he had already traveled to the Arctic five times and “was tired.” So he declined the offer. Secondly, they thought about James Clark Ross. Ross has just arrived from Antarctica where he had explored the Ross Sea and Island. In fact, the ships on that expedition were the same as those that would be used on this mission (two of Ross Island volcanoes They are called Erebus and Terror in honor of the ships). But upon returning to England, he became engaged to his future wife and decided that great explorations were no longer for him. He was followed by James Fitzjames (discarded due to inexperience), George Back (considered too controversial) and Francis Crozier (who, well, was Irish and that was more than enough reason to rule him out). Seeing the yard, John Barrow, second secretary of the Admiralty, called John Franklin. To this day no one knows why Franklin, who was already a legend at the time and was almost 60 years old, he said yes. But the fact is that, as I said, they left the vicinity of London that day in 1845. They stopped in Orkney and the convoy formed by the two main ships (HMS Erebus and HMS Terror), the HMS Rattler (the first English warship with steam propulsion) and a transport headed to Greenland. There they sacrificed ten oxen and the expedition began its solo journey. The search for the Northwest Passage The travels of Marco Polo are a peculiar book. Not only does it remain a very interesting precedent for current anthropology, but it served as an inspiration for many during the era of great exploration. The image you can see above is precisely the annotated copy of ‘The Voyages’ that Christopher Columbus had. In one of its versions, the Italian one from 1559, a Chinese province called Anian. We assume that it was from there that the geographers and explorers who discussed whether America was a new continent or, on the contrary, an Asian peninsula, got the name of the Strait of Anian, the separation between Asia and America that would give access to the Northwest Passage. It is what we know today as the Bering Strait and for years it was pure mythology. But, first, Ferdinand Magellan and his crew turned around Cape Espiritu Santo and found themselves face to face with the southeastern passage; and, second, a Dane in the service of Russia, Vitus Beringrediscovered for the West the strait through which Semyon Dezhniov had already traveled sixty years before. The rest was geopolitics: the quick passage to the Pacific without having to pass near the Spanish territories in America was too juicy. In 1745, an English law promised 20,000 pounds to whoever discovered the pass and the boom began. I have tried to convert the amount to a current currency and I have not been able to do it accurately, but I have drawn one conclusion: it was a lot of money. Favorable weather In early August 1845, two whalers, the Prince of Wales and the Enterprise, encountered Franklin’s ships in Baffin Bay. They were waiting for favorable weather to enter the Strait of Lancaster. That was the last time they were seen. Two years passed. And, little by little, Lady Jane Franklin, some members of Parliament, and the fledgling British press began to ask the Admiralty to send someone to search for the heroes of Franklin’s expedition. The Government sent three expeditions: one by land and two by sea, one through the Atlantic and another through the Pacific. They failed. Fearing that they would be forgotten, Lady Jane Franklin composed her lament, the song you can hear just above. And, although I don’t know if it was for that reason, the truth is that was not forgotten. In fact, the search for the lost expedition “became nothing less than a crusade.” In 1850 alone, eleven British and two American ships tried to locate them. It was then that the first tombs were found. Over the years, the different expeditions found fragments, Inuit stories and objects from the expedition. In 1855, following the indications of some Inuit tribes, pieces of wood were found with the name of Erebus. In 59 two messages were found. The first, dated May 28, 1847, was from Franklin himself and read “Sir John Franklin, Commander of the Expedition: All Well.” It is the document on the right. It was a common practice at the time, documents were left in different places so that, in case of problems, they could be reconstruct the details of the trip. But in this case, something curious happened: on the edges there was another message, dated April 25, 1848, explaining that the ships had been trapped in the ice. Franklin and twenty-three other crew members were dead. And the rest, the survivors, had abandoned the ships looking for an exit to the south. In the next few years some objects, some rumors and some tombs appeared. Nothing else. The ships never appeared and we never, in 150 years, discovered what had really happened to Captain John Franklin’s lost expedition. One hundred and fifty years without news In the 1980s, the University of Alberta launched a project to track the expedition. The different possible routes were traveled … Read more

Australia has decided to ban social media for those under 16 years of age. The mystery is how they are going to achieve it

by

December 10 was the date marked on the Australian calendar for prohibit social networks for minors under 16 years of age. Australia becomes the first country to implement a measure of this type, although there are others that also want to do it like Denmark or France. The ban is already in force, however there are still many doubts about how the measure will be enforced and how effective it will be. What exactly does it prohibit? The Online Safety Amendment establishes 16 years as the minimum age to have a social media account. This means that minors can access networks without logging into an account, which will allow them to consult public posts on social networks, watch YouTube or read Reddit threads. Without an account, they will not be able to access personalized feeds, receive notifications or communicate with other users. Currently, the amendment includes eleven services prohibited for minors: Instagram, TikTok, Facebook, Snapchat, X (Twitter), Reddit, YouTube, Twitch, Kick, Threads and Lemon8. It is not ruled out that the list will change in the future. How are they going to verify the age? The million-dollar question and the one that leaves us with the biggest doubt of all. The amendment details the prohibitions, but leaves it up to the platforms to do the work of verifying the age of their users. It does not say how they should do it, it only specifies that they will not be able to do it just by asking for the DNI and they will not be able to save data related to age verification. Although they do not establish rules on how to carry it out, the Australian Government published a report in which they concluded that age verification technologies were technically viable. In the report they analyze several methods: Checking documents and identity records. Age estimation using biometrics and facial recognition. Age estimation from the user’s behavior or fingerprint. Parental control mechanisms. Image: Wikipedia The doubts about the effectiveness We have the recent case of United Kingdom when it banned porn for those under 18. They also proposed various age verification methods such as those mentioned in the Australian report. The reality has proven to be more complex and, after the blockade, there were a brutal spike in downloads of VPN serviceswhich means that many users fake their location to bypass the block. The law is made, the trap is made. Furthermore, the system is not perfect. They count in NYTimes that some teenagers have used the facial recognition option in some apps and it has incorrectly estimated their ages. And there is also the issue of privacy. Although the law says that platforms cannot collect data from the age verification process, there is no standardization in this regard and if we have learned something after decades on the internet, it is that leaks happen. What are the platforms doing? Instagram, Facebook and Threads Meta has already done his homework. On November 20, it notified users minors under 16 that their accounts on Facebook, Instagram and Threads were going to be deleted. Regarding age verification, in September 2024 already announced “accounts for teenagers”which restrict certain features, such as making the account private by default and limited messages. To detect age, since April they have been using AI tools to detect users who lie about their age. In statements to Vergea representative of Meta has assured that the regulations “isolate adolescents from online communities and information, while providing inconsistent protection in the numerous applications they use.” TikTok and Lemon8 Bytedance apps have confirmed that from its entry into force, they will deactivate the existing accounts of those users under 16 years of age and will not allow them to create new accounts. Additionally, content from underage Australian users will be hidden. Regarding facial recognition, they offer several methods such as age estimation through facial recognition, credit card authorization, and verification of official identification documents. reddit Reddit has also started suspending the accounts of those under 16, but gives them the option to download their data first. In a post on the platformthey say that age verification will be done through “a prediction system.” The platform has taken a stand against this decision and states that the law “undermines everyone’s right to freedom of expression and privacy.” YouTube YouTube communicated that as of December 10, it would begin to suspend the accounts of those under 16, although they will be able to continue watching YouTube without being logged in since the law does allow it. They do not say how the age verification will be done, what they do say is that the new law is a mistake and that it will have a counterproductive effect since, by deleting the account, the possibility for parents to control what their children see will be lost, so minors will be even more insecure. snapchat In one publication on your website, Snapchat confirms that from December 10 it will block all accounts of those under 16. They will keep the account blocked for three years and if users turn 16 during that time, they will be able to recover it using age verification. Verification will be done in three ways: connecting the app with an Australian bank account, scanning the ID document and using the age estimation through a selfie. Twitch The streaming platform will prevent users under 16 from creating an account. For this they will use their verification system through facial recognition. Existing accounts will be deactivated starting January 9. Kick In the case of Kick, as published Guardianthey will use the same age verification system that Snapchat uses. X (Twitter) Elon Musk’s social network requested last September that the entry into force of the new regulations be delayed, as published Guardian. From X they expressed “serious doubts” about the legality of the regulations. What happens if the platforms do not comply? The law does not say how they should ensure that minors create an account, but it does say the consequences … Read more

The existence of lightning remains a mystery to atmospheric physics. Austria has given us a clue to solve it

by

It seems unbelievable, but in the middle of 2025 one of the most common and violent phenomena of nature continues keeping many secrets. This is the case of raywhich we know how to protect ourselves from and we know that Franklin had very right with your kite. But if we ask an atmospheric physicist what exactly detonates the first spark inside a cloud to start the download, you’ll probably shrug your shoulders. The discovery. We would expect the answer to this classic meteorology question in the sky itself, but in reality it seems to be in a laboratory in Austria. It has been here where they have achieved something that seems like magic: using lasers to trap microscopic particles in the air, and almost by accident, discovering a charging mechanism that could be the ‘missing link’ in the formation of lightning in our sky. What we knew. For lightning to strike, it is necessary that there is a monstrous electric field that breaks the resistance of air, something that has a name: dielectric breakdown. The problem is that when we measure the electric fields inside a thundercloud, the numbers don’t add up: They are too low to initiate lightning on their own. This means that scientists have long suspected that the secret was in the aerosols and ice crystals that collide within a cloud. And the theory is quite clear: if a small particle could accumulate enough charge, then it has the ability to create a micro-electric field around it so intense that it would start a chain reaction. The problem is that studying a microscopic ice grain in the middle of a storm is impossible, since we can be next to it and we cannot lower the cloud to the ground either. That is why this is where this research comes in, which has found a high-tech solution with optical tweezers. The experiment. To find the answer, a 532 nm green laser was used to make lift a silica sphere just a micron in diameter. But… Why? In this case, the initial objective was to measure forces precisely, but they encountered something very strange: the laser itself that held the particle was electrically charging it. Far from being a mistake, they realized that they had in front of them a perfect tool to simulate the atmosphere in miniature. It was no longer necessary to go to a cloud to analyze it. In this way, they began to charge a particle with so much static electricity that it caused a dielectric breakdown in the air around them, discharging themselves suddenly. They had literally created a controlled micro-ray in the laboratory. The authors of the study explicitly suggest that this system is an ideal model to study the electrification of aerosols and clouds. Its importance. Until now, studying these phenomena required getting into a storm-chasing plane or relying on computer simulations. But now we have the ability to simulate these conditions in a controlled way. And it is also ideal to understand why sometimes the sky seems like it is going to break in our own heads.

The mansions of the most exclusive urbanization in Spain are usually a mystery. Marc Márquez has opened it up a little

by

The MotoGP rider has had no shame in reveal the value of his mansion in La Finca, along with other details about how he manages an asset that exceeds 80 million euros. Far from the clichés of the millionaire athlete, Márquez talks about fiscal responsibility, professional advice and a clear philosophy: money has not changed his lifestyle (or at least not in everyday things). The mansion as an investment, not as a whim. Marc Márquez has resided since 2022 in La Finca, the most exclusive urbanization in Pozuelo de Alarcón, where he has neighbors such as Cristiano Ronaldo or Cristina Pedroche. His property, valued at around 10 million euros, has 1,300 square meters distributed in seven rooms, a gym, a two-story swimming pool and a minimalist aesthetic with straight lines and light tones. When asked about the price, the pilot responds: “10 million? Around there. That area is around there. But it is an investment,” according to declared on Imagin’s ‘The End of the Month Podcast’. He also states that “the house is paid for.” This case, in fact, It was owned by Mariano Díazformer Real Madrid player and current Deportivo Alavés forward. The jump to Madrid. The move from Cervera to the capital was not just a matter of comfort. According to revealed to ‘Todo Circuit’the decision was motivated by medical reasons, being close to his doctors after the injuries that have marked his career, and by logistical efficiency. “I save hours on the train, with events and commitments,” he explained. The Finca also offers you the privacy you are looking for, being a refuge where you can disconnect from the circuit without fanfare. The lesson of the first million. The path to economic stability began in 2013, when Márquez won his first MotoGP title at just 20 years old. That bonus of more than a million euros opened his eyes about money management. “More than 50%, bam!, Treasury. 10% for the manager, training motorcycles…”, remembered in that same interview. It was then that he met the lawyer who still advises him and learned the importance of not losing his mind: “They told me: ‘it seems like a lot, but it’s little, leave it in the bank.’” Since then, he assures that his advice is provided by a lawyer and an accounting manager, without limited companies. “I am self-employed, I am not a company, I do not have a SL,” he says. An empire beyond motorcycles. In addition to his residence, Márquez has diversified his assets with investments in the audiovisual sector with his brother Álex. They participate in companies such as Fast Brothers Productions, dedicated to film and series production, and Café Para Muy Cafeteros, focused on podcasts. They also founded Vertical Management SL, specialized in representation and advice of athletes and content creators, together with Vertical Content Creators SL and Bamboleo Events SL, the latter focused on organizing sporting events. With this network of companies, he not only manages his image, but also builds a professional future that will be very good for him once he retires from his profession. 2025, year of 10. His season with Ducati has been historic: he has won his ninth world title, achieved 11 victories in grand prix and 14 in sprint. This, according to Forbes, has reported him extraordinary income that totals more than 5 million euros in bonuses, in addition to his base salary of 12 million. Added to this are sponsorships with brands such as Estrella Galicia, Alpinestars, Shoei or Audi, which represent a substantial part of a total assets that exceeds 80 million euros. Money without posturing. “I’m lucky that money hasn’t changed my lifestyle,” says Márquez. “I have the same time with my friends anywhere, I don’t need to show off.” He has no debts, declares himself self-employed and maintains a low profile. “I don’t want to be in the newspapers or anything like that,” he confesses. It is the same solvency with which he rides a Ducati: a cool head, long-term vision and feet on the ground. In Xataka | An atoll in the South Pacific has become a magnet for millionaires.

The extinction of Neanderthals has always been a mystery. Science now believes that they are still with us

by

For decades, the disappearance of Neanderthals has been one of the biggest mysteries of human evolution. It happened about 40,000 years ago, suspiciously coincident with our species Homo sapiens to Eurasia… But now we are thinking that they did not become extinct. What was thought. Classical theories paint a replacement scenario: either we wiped them out in direct competition, or they couldn’t withstand brutal climate change. But now a study published in Scientific Reports offers a much more fascinating answer: we absorb them among ourselves. And the key to all this is genetic dilution. The hypotheses. To go deeper, the competition hypothesis suggests that Homo sapiens We were simply superior: we had better hunting strategies, a broader diet or more advanced social structures that allowed us to monopolize all the resources, driving the Neanderthals to extinction. On the other hand, the environmental hypothesis blames the drastic climate changes that occurred just at that time. According to this idea, Neanderthals could not adapt to extreme fluctuations and their populations fragmented until they disappeared permanently. However, the new study presents a mathematical model that leaves both factors aside and focuses on the most basic of all: demographics and sex. The new model. The authors of the study propose an analytical model that demonstrates how Neanderthals could disappear without the need for the Homo sapiens had any selective advantage over them. The model does not require “catastrophic events” or cognitive superiority. Instead, it relies on a concept called “species-neutral drift” and a key factor: small, recurring immigrations of Homo sapiens in Neanderthal territories. There were many more of us. One of the first ideas pointed out in this case is that the population Homo sapiens that left Africa was much larger in number than the Neanderthal, acting as a “practically infinite demographic reservoir.” By going together, because friction makes affection, and between the species they began to intersect and had very fertile offspring. The model assumes that this was not a one-time event, but rather a “sustained gene flow” that occurred every time a small group of modern humans arrived in an area. So, adding that the Neanderthal population was much smaller and there was a constant influx of genes from Homo sapiensthe result is the dissolution of the gene pool. It’s literally like pouring a glass of Neanderthal water into an ocean of Homo sapiens. In the end his presence is completely diluted. The time. The most powerful thing about the study is that its calculations fit with the archaeological record. The mathematical model shows that this process of “almost complete genetic replacement” could have occurred within a period of 10,000 to 30,000 years, something that aligns with the long period of coexistence that both species had in Eurasia. Were they extinct? This is the question we ask ourselves. Know if the word ‘extinction’ is appropriate for this paradigm. This model offers what scientists call a “parsimonious explanation” (the simplest). In words we understand, it does not deny that other factors, such as competition or weather, could have contributed. But it shows that this genetic dissolution alone is something that may have explained the disappearance of the Neanderthals. That is why, rather than an extinction, we speak of a fusion by absorption. This perfectly explains why the Neanderthals disappeared as a genetically distinct group, but their legacy endures: modern humans of Eurasian ancestry conserve in our DNA a small percentage of their genetic heritage (although very diluted).

This is how science has unraveled the mystery of Lake Tefé

by

The historic drought and heat wave that hit the Amazon in 2023 caused extreme warming and unprecedented in its waters, with devastating consequences that we are seeing today. A new study published in Science details how water temperatures in key lakes reached lethal levels, causing high mortality in fish and especially river dolphins. Very high temperatures. A priori we may think that heat waves just as they come will go away without leaving any consequences. But the reality is very different, since in the Amazon, of the ten lakes that were monitored, five exceeded 37ºC during the day and there was one that reached 41ºC as if it were a spa pool. This extreme heat wasn’t just skin deep; It penetrated the entire water column, approximately 2 meters deep, eliminating any fresh refuge for aquatic life. It was literally left uninhabited. Epicenter of the tragedy. Lake Tefé, which is normally more than 7 km wide, became the focus of national and international attention after its surface area will be reduced by 75% between September and October 2023. It is literally a consumption never seen before that surprised the inhabitants of the area and also the animals. This drastic reduction in water coincided with a “massive and unprecedented mortality” of river dolphins. In a short interval, 209 dolphin carcasses were found (both from the Amazon River and Tucuxi). And precisely, the study points out that only on September 28, 2023, when temperatures reached 39.5 °C for the first timeseventy dolphin carcasses were found. The researchers also observed extreme daily temperature variation of up to 13.3°C, meaning the water went from hot tub-like heat during the day to drastically cooling at night. completely altering the conditions of the system. And living there becomes really complicated. What caused this extreme heat. The study used models to identify the culprits behind this warming. It was a “perfect storm” of factors that coincided such as high solar radiation due to completely clear skies that could not stop the sun. But the reduced depth of the water or the low wind speed also intervened, which generated less cooling due to evaporation. A long term problem. While the 2023 event was extreme, it is not an isolated incident. Study reveals worrying long-term warming trend in region, Based on satellite estimates, between 1990 and 2023, the lakes in the Amazon region have experienced a temperature increase of 0.6 degrees per decade. A great ecological crisis. The impact was not limited to the dolphins. The study also documents significant fish mortality. All because of the fact that they have a fairly narrow temperature tolerance range, meaning that the moment there is an increase, even a slight one, in temperature, they are finished off. For human populations, the consequences were equally serious. The drought and extreme heat managed to isolate thousands of people in riverside communities, leaving them without adequate access to food, drinking water and medicine because maritime transport is also severely affected.

science has solved the mystery of plasma rain

by

Although it may seem incredible, it rains in the Sun. But it is not a rain of water like the one we know on Earth. It’s a rain of incandescent plasmaa phenomenon that for decades has baffled scientists by not understanding it. Now, a team from the University of Hawaii has solved the mysteryand the answer is completely changing our way of understanding the atmosphere of our ‘reference’ star. The discovery. Published in the prestigious magazine The Astrophysical Journal, not only explains why these spectacular plasma condensationsbut also gives us new tools to predict space weather that affects our technology here on Earth. The mystery. The “solar storm“, or more technically coronal rain, occurs in the corona, the outermost and hottest layer of the Sun. There, masses of denser and relatively “cold” plasma condense and fall back towards the solar surface, creating bright arcs and loops. And although we talk about ‘cold’, the reality is that we are talking about tens of thousands of degreescompared to the millions of degrees in the surrounding plasma. Although for us it would be something unthinkable. The big enigma was speed. Solar models predicted that this cooling and condensation process should take hours, or even days. However, observations showed that rain formed within minutes during solar flares. Something didn’t add up. Now the problem has been located in the models that were used. And they assumed that the chemical composition of the corona was static and uniform, a simplification that has undoubtedly resulted in us calculating the phenomena that occur in our star much worse. The key. The key breakthrough came when the researchers, led by graduate student Luke Fushimi Benavitz, decided to abandon that old assumption. They introduced into their simulations a factor that until now had been overlooked: the abundance of chemical elements varies in space and time without being static. And this is where physics gets very interesting. The mechanism. The first thing that happens in this case is a solar flare that heats the chromosphere (the layer below the corona). This impulsive heating causes a large amount of plasma in the chromosphere to “evaporate” and rise at high speed towards the coronal loops. This ‘new’ plasma will have a composition similar to that of the photosphere, which is the surface we see of the Sun. Once the plasma was already in the coronal loop, rich in materials such as iron or silicon, it is pushed and concentrated at the highest point of the arc, creating a ‘peak’ with these elements. One property of these elements is that they can radiate a lot of energy quickly and this causes the plasma to cool. And this sudden concentration at the apex of the loop acts as an ultra-powerful radiator, causing localized and very rapid cooling. Finally, this sudden cooling causes a pressure drop. As a result, more plasma from the surrounding area is sucked into that area, increasing the density. The most interesting thing is that the higher the density, the cooling becomes even more efficient and a ‘thermal runaway’ occurs. As its name indicates, the temperature will plummet and the plasma will condense, forming rain. The importance. For the first time, this model has done something that had not been achieved before: simulate the formation of rain on the Sun. And understanding it goes far beyond solving an old riddle, but it affects us completely. Most importantly for us, it improves our ability to predict space weather. solar flares They can launch enormous amounts of energy and particles into space which, upon reaching Earth, can damage satellites, disrupt communications and overload electrical networks. More precise models of the Sun’s behavior allow us to better anticipate these events that until now gave us very little preparation time. Rewriting. This discovery forces us to rewrite a fundamental part of solar physics. The idea that the composition of the solar atmosphere is dynamic and not static opens a large field of research ahead to understand exactly how energy moves through the star.

There is a mystery customer spending 10 billion on Broadcom chips. Nobody knows who he is and that should worry us

by

Charlie Kawwas, president of semiconductors at Broadcom, confirmed yesterday that OpenAI is not the mysterious client who signed up to pay $10 billion in custom chips. In September the existence of that enigmatic client became known and there was unanimity assuming that it would be OpenAI. But it turns out it’s not OpenAI. “I would love to receive a purchase order for 10 billion from my good friend Greg,” Kawwas said. referring to Greg Brockman, president of OpenAI. “He hasn’t given it to me yet.” Why is it important. During the Cold War, nuclear installations could be counted from satellites. In the AI ​​race, someone may be building the computational equivalent of a nuclear arsenal and we have no way of knowing. AI chips are the new strategic weapons. And unlike enriched uranium, they travel discreetly in commercial containers. An entity with $10 billion to spend on custom semiconductors is building AI capability on a beastly scale. The candidates. The analysis rules out the usual suspects: Meta and Google They are already known Broadcom customers. amazon has its own chip strategy with AWS. Microsoft invest through your partner-friend-enemy OpenAI. More disturbing options remain: Gulf sovereign wealth funds with technological ambitions. Government entities Americans (NSA, classified projects). Chinese actors operating through intermediaries. Apple preparing a major play in AI. This last option would be the canary in the mine to anticipate Apple’s total immersion in AI, but the parakeet Gurman has not anticipated anything, so it sounds like a very remote option. The money trail. Broadcom does not announce the arrival of these types of customers by chance. In September, CEO Hock Tan mentioned this $10 billion order because it completely changed the company’s revenue projections for 2025. Broadcom shares are up more than 53% so far this year. And in 2024 they will already double their value. The market always values ​​these secret contracts even if it does not know who signs the check. In perspective. Opacity in AI infrastructure investments has become the norm. Companies treat their component strategies as classified information. OpenAI just announced 33 gigawatts of computing capacity between agreements with NVIDIA, AMD and Broadcom. One gigawatt can cost $50 billion. The figures are stratospheric, but at least we know who signs them. The alarm signal. When $10 billion in critical technology changes hands without identification, we have a problem because computational training capacity, in the age of AI, is geopolitical power. This case is also a message about the immediate future: the next technological revolution may be developing outside of any public scrutiny.
