The last great finding only confirms how little we know about it

by

The moon always shows us the same facea family face full of dark “seas” of basalt. But what about his hidden face? For decades, we have known what is radically different: More mountainous, with a thicker and firing cortex of craters, but with much less volcanic activity. This enigma, of having a moon with two faces, has been one of the great mysteries of astronomy. Now We are getting to know More details of its composition. As. The key lies in the first rock samples brought from the hidden face of our satellite by Chinese mission chang’e-6 that has given us the key to continue investigating in this line. That is why a research team from the University of Peking and College London University He has discovered that the interior of the hidden face of the moon is significantly colder than that of the visible face. And this temperature difference is key to everything. The analysis. When starting to study the fragments extracted from the Aitken basinscientists have confirmed the first of all the age of the stones. Specifically, they have seen that these rocks were formed from Lava about 2.8 billion years ago. But the real surprise came to see the chemical “thermometer” of its minerals. The results, published in the prestigious magazine Nature GeoscienceThey show that this lava was formed at a temperature of about 1,100 ° C. That said, it may not seem much, but it is approximately 100 ° C longer than the lavas that gave rise to the seas of the visible face, according to the samples brought by the missions Apollo and Chang’e-5. “The visible face and hidden face of the moon are very different on the surface and, potentially, inside. It is one of the great mysteries of the Moon. We call it the two -sided moon,” explains Professor Yang Li, co -author of the study. Testing. Faced with evidence like this, the only thing that can be done is to be sure of what is being said, and for this the scientific team arrived a second method of analysis. In this case, the satellite remote sensing data of the Chang’e-6 landing zone with a similar age region on the visible face were compared. The result was consistent: the potential temperature of the mantle of the hidden face was about 70 ° C lower. In this way, there was no doubt: the interior of the hidden face was colder. Because. The answer seems in this case a “cocktail” of chemical elements that has been called from Kreep. This acrononic groups Potassium (K), Phosphorus (P) and Rare Earth (REE), which in turn is also accompanied by radioactive elements such as uranium and thorium. The key to all this, which is the elements act as an internal “thermal blanket.” As they disintegrate radioactively, they generate heat, maintaining the hottest mantle for longer and favoring volcanic activity. But the truly interesting thing is that the Kreep distribution is not uniform, but is almost everything concentrated in the visible face of the satellite. This is something that Chang’e-6 samples confirm Retrieved: the basalts of the hidden face have a less or insignificant Kreep component ‘. Without that extra heat source, its mantle cooled faster, the bark became thicker and, therefore, volcanism was much more scarce. The final mystery. This matter does not stay here, since more questions are raised in this regard, such as why all the Kreep material ended in the visible face? This question is not answered by this study, but confirms the real thermal asymmetry of the moon, giving more weight to several fascinating theories. Among them is one of the most accepted hypotheses that points to the gigantic impact that formed the Aitken basin in the hidden face (the largest crater of the solar system). In this case we talk about being so violent, the impact pushed the magma rich in Kreep to the opposite side, the visible face. Another theory suggests that the Earth initially had two moons. The smallest ended up slowly colliding with the largest, forming the thickest bark of the hidden face and explaining the composition difference that has now been demonstrated. But in the end we are talking about hypotheses that must still be confirmed in subsequent studies.

We believed to know what killed Napoleon’s army in Russia. The finding of a tooth has shown us something else

by

In 1812 there is a moment that was going to be registered in the history books. The Russia invasion by Napoleon culminated in one of the greatest military tragedies: The great arméeformed by more than half a million men, was forced to a devastating withdrawal marked by hunger, cold and disease, a combination that cost the lives of hundreds of thousands of soldiers. Or we believed. Health catastrophe. In the summer of 1812, Napoleon Bonaparte gathered up to 600,000 soldiers for his campaign against Russiathe greatest force he had ever deployed. However, the burned land strategy of Tsar Alejandro iwhich involved Evacuar Moscow and deprive the supplier of supplies, forced the withdrawal of the French army to Poland during a brutal winter. Between October and December of that year, more than 300,000 men perishedvictims of hunger, the extreme cold and a wave of diseases that devastated to an already weakened force. For a long time, the testimonies of survivors and the first scientific analyzes pointed to the TIFUS and the trench fever as the main culprits, reinforcing the idea that the bad hygienic conditions had sealed the fate of the great Armée. The new findings. Now, research carried out In the Pasteur Institute in Paris they have contributed a more precise vision thanks to metagenomic techniques, capable of identifying genetic material of any pathogen present in human remains. Nicolás Rascovan’s team analyzed Thirteen soldiers Buried in Vilna (current Lithuania), epicenter of mortality during the withdrawal. The results did not detect traces of typhus or trenches fever, but they did reveal the presence of Salmonella Entericacause of paratyphoid fever, and Borrelia recurrentis, transmitted by lice and responsible for recurring fever. These diseases, although not always fatal, would have deeply weakened soldiers already exhausted by endless marches, lack of food and glacial temperatures. In that context, even pathologies that in other circumstances could have overcome became mortal. Napoleonic invasion in Russia Lethal combination He New scenario It suggests that defeat is not explained by a single infectious agent, but by a devastating combination: physical exhaustion, starvation, extreme cold and a set of diseases that, together, undermined the resistance of tens of thousands of men. The Parathyphoid fever It would have caused diarrhea and dehydration, while recurring fever progressively weakened with cyclical episodes of high fever. All this, added to the lack of hygiene, to the spread of lice and the impossibility of adequate medical care in the middle of the chaos of the withdrawal, turned the Napoleon army into a paid field For the disease. The magnitude of the health catastrophe even exceeded combat losses, and became one of the decisive factors that precipitated the collapse of the campaign. Historical and scientific implications. Although some experts warn that the amount of recovered DNA is reduced and that the results are not entirely conclusive, The study It marks an important advance in the use of modern tools to reinterpret historical episodes. Demonstrates the Metagenomics potential To trace diseases in ancient human remains and offers new perspectives on how biology, and not only military strategy, it can explain the collapse of whole armies and populations. Researchers They point That these techniques could also be applied to the study of communities in America and Australia after European contact, where the lack of reliable records and historical biases make it difficult to understand the true impact of epidemics. The defeat that sealed the empire. The Tragedy of 1812 It is still one of the most studied inflection points in military history. The collapse of the Great Armée Not only stopped the Napoleonic expansion, but triggered the offensive of his enemies and the beginning of the end of his empire. While the epic of the campaign has traditionally been narrated in the key of battles and strategic decisions, the New evidence They confirm that biology and disease played a central role in the debacle. The withdrawal of Russia was, ultimately, both a military disaster and an epidemiological catastrophe, and the DNA of a few teeth found in Vilna has allowed to illuminate more precisely the executioners invisible and tiny that decimated the soldiers of Napoleon in one of the most lethal winters in history, starting with an unexpected “army” of lice.

In León there are small villages that are finding a peculiar phenomenon: thousands of “ghost tourists”

by

In the world there is good and bad touristsrespectful tourists and disrespectfulclean and others capable of converting places such as Everest either The Fuji In authentic stercolera, but much less common is what some peoples of the province of León are living. His municipalities are finding a kind of “Ghost Tourism”a drip of thousands and thousands of travelers that nobody has seen or heard or housed, but that in theory they have visited the town. Or at least he assures it A study of the INE. Multiplying the census by 24. Carbajal sources It is a town of León located about 50 minutes by car from the provincial capital and surrounded by hectares and hectares of cultivation. It doesn’t usually sneak into the news, but Monday León News He dedicated him A broad article which explains a peculiarity of the people: in summer there are few municipalities in which the population shoots more for tourism. According to A study INE experimental that measures the flow of tourists from the position of mobile phones, between July and August 2024 the town received 1,826 tourists. Many do not seem like many, but it is that INE himself acknowledges that in the Leonese town there are barely registered 76 people. That is, when the heat arrives, the summers multiply by 24 the municipal census. Next to nothing. “It’s a mockery”. Such data would be compressible if Carbajal sources had a natural park, an old fortress, parties known throughout the community or some other claim that explains that avalanche of visitors, but the City Council itself itself Recognize that this figure of 1,826 tourists (464 in July and 1,180 in August) is difficult to explain … and even more difficult to assume. “It is a burial,” nods The mayor of the town, Carlos de León Saluds, in León News. Similar opinion, Ana María Ortega, former mayor and councilor, Explain That one thing is that the influx of visitors increases in July and August for the people who returns to the village or visit to their relatives and a very different one that the data is triggered in an exorbitant way. “In summer you can triple the population, but multiply by 24 the number of inhabitants with veraners and tourists cannot be.” So … what happens? To understand that mysterious “Ghost Tourism” the first thing is to go to the prine sources. The data of the 1,826 tourists leaves a new “Experimental Statistics” of the INE that resorts to the signals of the mobiles to calculate different metrics related to tourism: the place of origin of foreigners arriving in Spain, the destinations that visit the Spaniards when they leave the country and the movement between communities, provinces and municipalities. The study has been prepared for a few years and always talks about the same: “Tourists.” If we consult the “internal tourism” data and more specifically the flows of “Interprovincial tourists” Residents in Spain, classifying the results by municipalities, the surprise arrives: in July of last year Fuentes de Carbajal received 646 and in August 1,180. In total 1,826. The question is therefore … how are those figures calculated that collide the mayor and the former mayor of the people? Mobile and antennas matter? The response is given by INE in The technical file From the survey: the data is related to the position of mobile phones and are obtained thanks to the collaboration of the country’s large operators. The approach is interesting and promising, but implies certain challenges. “The location of mobile phones is estimated from mobile phone antennas”, collects the institute itself: “This implies that the location of a mobile is not established with total precision, and the error depends on the concentration of antennas.” In summary, the more mobile antennas, the greater precision. Unraveling the mystery. The INE’s ability to analyze the data is also limited. The records on mobile location are anonymous and processed each operator, so the institute receives only aggregate data and in tables, without option to examine loose values. In rural areas it is also found that the low density of the network conditions the type of ‘cells’ with which it operates. By statistical secret, the institute also hides certain data. With that information about the Ortega table Slide that the balance of carbajal sources (which is so adjusted to what is perceived in the people itself) may be due to technical issues, such as coverage or that for some reason the data of other municipalities are added to those of the Leonesa Villa, thus blurring the real photo. Near Fuentes de Carbajal there are other villas with a balance of zero visitors. In Xataka we have already addressed the INE to ask him about that apparent mismatch. Is it the only case? No. León News Informs other equally striking, although none reaches the level of carbajal sources. In San Millán de los Caballeros, for example, the INE registered 1,648 tourists in July and in August 1,602, which adds 3,250. Again they may not seem like many, but it is that the town has 191 inhabitants registered. The same occurs in Izagre, of 137 residents and who according to the statistical institute receives almost 2,000 Veranians. “We don’t have great parties, just four performances during the summer,” remember the mayor of San Millán. “There are two campsites close to the people, but they are in the municipal terms of Valencia de D Juan and Villamañán.” Nor does the Izagre councilor achieve to understand everything that happens: “On central summer days, with the holidays, between 150 and 200 people can be reached in each of the villages, but reaching the 1,987 veraneantes in those two months cannot be.” Images | Zed Mendez (UNSPLASH)Google Maps and Wikipedia Via | León News In Xataka | It is increasingly easy to see from the road a crop that had never been dominant in Spain: the pistachio

In Galicia they have tired of finding garbage outside the cubes. So they will begin to rummage in it to fine their owners

by

In Sanxenxo They are fed up of finding trash out of the containers. Hence, the cleaning service and the local police of this coastal municipality of Las Rías Baixas, very popular as Tourist destination During the summer months, they have assumed a peculiar task: rummage in the bags to hunt receipts, tickets or any other track that reveals who has skipped the ordinance. And the City Council already warns: the ‘joke’ can be expensive. What happened? That Sanxenxo, a municipality of the Pontevedrés coast, He said enough. Its authorities have tired of being garbage bags outside the containers spread throughout the people and want to cut that annoying root habit. As? Searching on the bags to identify their ‘owners’. And how will they do it? In A statement Published on Tuesday the City Council explains that the concessionaire dedicated to the collection of waste, Ascan, will be responsible for “analyzing” the bags thrown out of the collection points to “locate the offender.” It will also do so from the hand of the Municipal Police and with a strategy worthy of the classic detectives. The operators will look for receipts, cards or any other track that can reveal where the bag came from. What if they locate the person in charge? Sanction. The Galician City Council recalls that those who skip the Environmental Protection Regulations, public cleaning and garbage collection face a fine of up to 600 euros. After all, The Consistory insistsArticle 39 of that rule makes it clear that pouring garbage into “unauthorized places” is considered a very serious infraction. Why do you do it? Because over the last days the Consistory has encountered garbage bags thrown in the center of the town, in areas as crowded as Consistory or Praza do Pazo, although it has also located abandoned waste in other parts of the interior of the municipality. In Sanxenxo there are some 18,000 neighbors registered, according to the latest INE data, but the number of people who walk and spend the night in the town He shoots every summer. Some estimates They point out that its population It is quintupple During July and August and, at least in 2020, the town had 11,100 second residences. Only in August last year the INE registered 70,000 travelers housed in hotel stores. To give services, to them the usual neighbors, the town has 2,000 containers and 651 islands of waste, spaces that the City Council wants them to use yes or yes. Although it must resort to fines to achieve it. Is it the first to do it? No. Sanxenxo is not the first town hall to which it occurred to search in the garbage bags to hunt offenders. Before they have already done other municipalities in the country, with disparate results. Similar measures were raised in their day in Sherry, Barcelona, San Sebastián either Seville. In the case of Donostia, In 2015 The Consistory ended up issuing an order so that the operators in charge of the collection of garbage stopped opening the bags. The decision was made after the complaint of a neighbor they had fined 250 euros.

In case not finding waiters were not enough, the hospitality faces a new problem this summer: where to accommodate them

by

According to a recent report Prepared by Obsbusiness School, tourism represents 15.2% of the total of the national economy and 2025 has all the signs of becoming a year of record for this sector, with an estimate of 98 million tourists, which represents an increase of 4% compared to last year. These tourists will spend about 138.5 billion euros. The data from the Ministry of Industry and Tourism They pointthat the sector will use a total of 2.99 million people. Such and as they highlight in Five daysthe main problem facing the hotel sector is not just the Personnel shortage. Is that, although they can hire workers to cover the high season in summer, these They cannot be paid The accommodation by the High price of rentals In tourist areas. Homemade. According to the last ‘Rent prices report in Spain’ Published by Idealista, the average price in Spain is 14.5 euros per square meter. That is, a 60 square meter accommodation should cost about 870 euros. However, the price increases when we approach tourist areas such as Málaga (16.3 euros/m2), Balearic Islands (19.7 euros/m2), Barcelona (23.9 euros/m2). In the case of the Balearic Islands, for example, the rent of a 60 -square -meter house would amount to 1,182 euros, a figure that can be doubled in high summer season. The high price of rentals makes it unfeasible that workers from other territories move to the main tourist destinations during the months of greater influx because, literally, The salary is gone Only in the rent. Work and accommodation. The hoteliers of the Balearic Islands were the first to alert the situation. Hotel chains Meliá, Riu, Barceló and Iberostar had planned increase your templates To meet summer demand. Due to the difficulty of finding accommodation for their new employees, chains have been forced to reserve a part of their facilities as accommodation during the summer months, offering it for free as an incentive to attract qualified talent. Hospitality entrepreneurs in the Canary Islands, meanwhile, They offered to build homes at priced price to rent to workers in the sector. However, the Ministry of Tourism estimates that only about 455,000 employees work in these large chains that have enough financial muscle to assume the cost of the accommodation of its employees. The other 2.5 million remaining employees belong to restaurants, bars and other small businesses. That leaves them with a serious problem, no longer due to lack of labor, but because rental price It makes someone from outside move during the high season to work. The only way out: adapt. It is materially impossible that the supply of local labor covers all the demand for the hospitality during the high season, so, given the impossibility of hiring more personnel, restaurants and small hospitality businesses of those those Tourism areas “Tensioning“They have chosen to adapt and reduce their care schedule depending on their staff. According The data of the Turijobs Employment Portal published by Self -employed and entrepreneurs87% of restoration businesses have had to apply these time adjustment measures to adapt to the lack of personnel. Desestationalization of tourism. One of the objectives of the tourism sector is Destationalize itTo, thus stabilize demand throughout the year allowing a more rest and economic continuity market, instead of focusing all the activity in the summer months. As they highlight in The countrypart of that goal is being achieved, and during the first three months of 2025 it has been increased by 5.7% The number of tourists, so that the tourist season is now ahead of May and ends beyond October. The de -stationalization of tourism would allow employees to settle in these destinations throughout the year, not only during the summer months, stabilizing in turn the availability of a sufficient local workforce. Long -term strategies. Given an unlikely scenario of moderation in rental prices, the most affected companies in the sector have adopted a long -term local personnel collection strategy. Thus, the dependency of personnel from other autonomies is reduced and, with it, the problem of accommodation. Portaventura World and University Rovira and Virgili signed a training agreement In 2024 for 150 employees per year. This agreement offers, in addition to a training accreditation, a job at the facilities and the Tourist Resort of Port Aventura once the training is finished. In the same line the initiative of the hotel chain THB Hotels moves that, through Your program THB College has offered accommodation and training to more than 2,000 employees since its creation in 2014, eliminating the problem of the shortage of qualified and accommodation personnel for them.

In 2021 a volcano spent three days in eruption without anyone finding out. Now it helps us ahead of the silent volcanoes

by

Knowing how to read the signals that a volcano gives before erupting can make a difference between a scare and a tragedy. Some volcanoes make it easy for experts who know how to read these clues but others erupt without prior notice. Or maybe just we couldn’t decipher your signs. At least until now. A new tool. A team of researchers He has devised A new mechanism to model the behavior of some volcanoes. This tool, its creators stand out, will serve to more effectively monitor the eruptions of some volcanoes reducing the risk associated with these natural phenomena often so violent. Some special usefulness in the case of “silent” volcanoes. “Despite great advances in monitoring, some volcanoes erupt with minimally detectable or even without them precursors, significantly increasing the risk of nearby populations,” pointed in a press release Yuyu Li, co -author of the study. As explained by LI herself, some of these volcanoes are located not only near communities, also near important air traffic routes. Silent volcanoes. For the development of its tool, the team resorted to the Veniaminaf volcano, located in the North American state of Alaska. This is one of the so -called “silent” volcanoes, volcanoes whose eruption is not preceded by the signals that are generally associated with an imminent or close eruption, such as earthquakes or the deformation of the soil in the surroundings of the Magma Chamber. Veniaminof’s is just an example that We can find In this family of silent volcanoes that also includes some closer such as Stromboli in Italy or Popocatepetl in Mexico. Looking inside the volcano. But among all of them, the Veniaminof volcano is perhaps the most paradigmatic. Not because only two of the 13 rashes that have leaded since 1993 have been planned, but because in 2021 he achieved the milestone of erupting without anyone noticing Until three days later. The team responsible for the study analyzed the internal conditions that make it a silent volcano. Factors such as a slow supply of magma and a warm host rock are key in this regard. The monitoring of the volcano was carried out for three summers prior to one of the silent eruptions of the volcano, that of 2018. A model to get ahead of the eruption. The result, a model that conforms to the state of different variables that can condition the probability of the burst of the magma, such as the volume of the reserve, flow conditions of the magna, depth of the reserve or the form that it acquires is. Thus they could estimate what kind of conditions could be linked to a silent eruption and which ones were not. The team found that soil deformation could help prevent some eruptions of the volcano but that the relationship between underground magma and rashes were somewhat more complex than it might seem. The details of the study have been published In an article In the magazine Frontiers in Earth Science. The following steps. Monitoring the numerous silent volcanoes distributed throughout the world will not be an easy task. For now, the resolution gives a clue to what are the volcanoes to monitor more closely: volcanoes with small and warm reserves and slow magma flows, explains the team.

There is already a detainee for using the Meta Ray-Ban to record without consent. Recorded hundreds of women in Barcelona without finding out

by

A young man has been arrested in Barcelona After recording hundreds of women with smart glasses without their knowledge. What he did with those recordings: use them in their “seduction” courses that sold for 3,000 euros. Why is it important. It is the first known case in Spain where Ray-Ban Meta They are used to commit crimes against intimacy. The victims did not know that a camera that they did not detect recorded conversations about personal information that later disseminated and monetized. The facts. The detainee approached foreign tourists in Barcelona, ​​held apparently casual conversations and recorded them with glasses that had an integrated camera. Without noticing it, and in fact hiding it. The videos were later published in Tiktok and Instagram as a claim for their “seduction techniques” courses. In figures: 329 videos analyzed by the police. 239 Conversations with intimate data of women. 700,000 visualizations reached the video of the complainant. 3,000 euros cost the full course (plus 45 euros per month of subscription) The technical problem. The Ray-Ban Meta (329 euros) emit a white light when recording, but it is easy to hide them with small tricks. The majority of victims did not detect being recorded, according to police investigation. Smart glasses pose a privacy dilemma that we had not had to face so far, although it already anticipated a decade ago with The Google Glass opening the way. Ray-Ban Meta are much more concealed. Let’s not talk compared to a mobile. Yes, but. Goal designed a safeguard: the indicator light. The problem arises when malicious users deliberately avoid them to record without consent and then make malicious use, or at least to monetize or spread them. Goal is preparing more AI functions for these glasses that will identify places or people in real time. Some users have achieved it on their own. This arrest promises to be the first of many conflicts that are yet to come between body technology and privacy.

Chrome’s extensions have a big problem. Anyone can buy them and fill them with malware without finding out

by

One day John Tuckner decided to try to be evil. He found a browser extension called “Website Blocker” that could buy for $ 50 and took it. The extension, which allows to block certain websites so that the user is not distracted with them for some time, was especially interesting because it allowed to reuse it for spam attacks. And then things happened. Sight problem. In just a few days I had control of the extension and could do what I wanted with it. He modified the code, published the update and confirmed that the novelties had reached all users without being found. And then told what was happening: He is the founder of the cybersecurity company Secure Annex, and wanted to confirm their fears: there is great danger with extensions: anyone can buy them, modify them and reuse them for all kinds of purposes. Google reviews the modifications, but “it is not clear about what level of scrutiny,” Tuckner explained. Another recent case. At the end of January the creator of the Browser Boost Extra Tools for Chrome extension sold this development and transferred it to its new owner. Its 30,000 users were soon exposed to the new code, which dynamically redirected websites that the new owner decided unilaterally. I have not been. One of the extension users He warned of the problem in the github repository of the extension and analyzed the code notifying the danger of malware that could reach due to the new owner. The creator, n0m1111, explained who had sold the extension months ago and was no longer responsible for the code. Playing with permits. These extensions often allow permits of all types of browser parameters. Tuckner explained how in the extension he bought a permit called “declarativemetretreQuest” was used that was very wide and allowed to redirect users to false authentication sites to steal their passwords. Other permits would allow the owner of an extension to take screenshots with sensitive information or access the cookies that the browser keeps to steal data from the browser sessions. The possibilities are multiple and in Xataka we already talked a few months ago about how extensions They are becoming a silent method to infect users. A recent attack. In February, the Gitlab Threat Intelligence expert team They discovered A group of 16 Chrome extensions “used to inject code into browse to facilitate advertising and SEO fraud.” Among them they added 3.2 million users, and in Gitlab confirmed that the extensions had been bought and then modified, which allowed to avoid suspicions by users and the industry itself. These experts notified Google of the problem, and the company eliminated them all in January 2025. Block extensions, the solution. If you want to protect yourself from these problems, the solution is block The execution of extensions in your browser, especially in computers that handle sensitive data such as work. Unless they are extensions of trust, these types of problems can cause serious security problems. Care with permissions. Browser extensions can end up being bought, sold and reused without notice by their new owners, as has been the case. That raises a serious problem for users and companies, which before installing an extension should provide A lot of attention to permits that ask for these extensions to work. What do they say in Google. In Xataka we have contacted Google responsible and we will update this article if we receive new data on the subject. Be that as it may, the company offers A HELP DOCUMENT In this regard and also indicated in a Article in your official blog How to stay safe with the use of extensions in Google Chrome.

Finding quick and reliable tests for Alzheimer’s is a key mission for science. And we have a new candidate

by

Ahead of Alzheimer’s. It is a simple but difficult objective to achieve since the symptoms of this disease tend to appear when the disorder is advanced and has already caused important damage to our brain. A difficult objective but what It can help us treat the disease With greater efficacy, managing to delay the appearance of some of its symptoms such as cognitive deterioration. Maybe one day helps us cure it. In the blood. A group of researchers has tested a new blood test aimed at the early detection of Alzheimer’s disease. The test is based on a biomarker present in the blood, P-TAU217, which shows changes long before the appearance of symptoms in people with the disease. The study showed precision when detecting the disease greater than 90%. These results also did not depend on the age or gender of the participants, either on the existence of comorbidities or whether the test was carried out by specialists or primary care personnel. This marker can be measured with simple and cheap tools and the process is automatic, which can facilitate detection in various circumstances, democratizing the diagnosis of the disease. “This is an important step to bring simple blood tests for Alzheimer’s disease to health systems around the world,” said the team responsible for the essay in a press release. P-TAU217. Detection methods based on the P-TAU217 compound They are not exactly new. These types of tools are already implemented in the United States and it is expected that they will soon reach the rest of the world, says the team itself. The new method seeks to offer a simpler alternative to the available tools. The new study analyzed the precision of this New Test in the conditions in which it would be used, not only in specialized clinics but also in primary care. In three countries. The essay was carried out from 1,767 participants with cognitive symptoms distributed in three countries: Spain, Italy and Sweden. The details of the study were published In an article In the magazine Nature Medicine. The New Test included two cut points. One of them served to interpret the negative results: from this threshold the test rules out the presence of the disease. The second of the cut points serves to find the positive ones: this threshold shows the presence of the disease. This leaves, between one cut and another, a “gray zone” in which the results are inconcuing, however the use of a test with a single threshold slightly reduced the accuracy of the diagnostic tool. Above 90%. The study showed that the test achieved an accuracy between 92% and 94% when used in its two cuts mode. However, this precision fell to levels between 83% and 87% when only a cutting point was used and applied to more advanced ages. “When the method was tested in patient sides, the precision was between 92% and 94%,” NOëlle Warmenhoven explainedfirst signer of the study. “This is promising since this method will probably become one of the most used in clinical practice around the world.” In Xataka | We have a new “theory of all” to understand Alzheimer’s.

the challenge of finding 500 billion dollars for the largest AI project

by

He Project Stargate announcement This week was surprising for many things, but above all it was surprising for one: the 500,000 million dollars that will theoretically be invested in the next four years to achieve its objectives. The figure, absolutely colossalhas generated many suspicions. And rightly so. 100,000 million to start. Of that total figure, the announcement made it clear that the companies that provided the capital would invest “100 billion dollars immediately,” but even that does not seem easily achievable. SoftBank and OpenAI, those who will invest the most. In The Information reveal that SoftBank and OpenAI will contribute $19 billion each for the Stargate project. Bloomberg duck that both will also be the ones that will have the most participation in the final company: each will have a 40% participation. Musk attacks, Altman defends himself. The announcement of the project provoked a quick reaction from Elon Musk, who stated in X that “Actually they (the companies involved) do not have the money). He later added that “SoftBank has less than $10 billion guaranteed. I have good sources.” Sam Altman responded to those allegations hours later indicating that the data that Musk provided was “Incorrect, as you probably know.” Musk and xAI compete with OpeenAI and maintain a long rivalry, but here Altman surprised further telling Musk that “I truly respect what you have accomplished and believe you are the most inspiring entrepreneur of our era.” SoftBank under review. Analyst MG Siegler indicates in your newsletter that SoftBank has about $30 billion in cash. It seems to have room for that initial investment, but there are other data that work against it. As indicated user David Manheim on X, SoftBank’s investment fund has had notable failures in the past. On Wikipedia you can see how SoftBank Vision Fund lost $27.4 billion in 2022 due to several failed investments led by Masayoshi Son, the CEO of SoftBank. Among them is the investment of 100 million dollars in FTX, which then collapsed. OpenAI burning money. There are also questions about OpenAI’s ability to invest that amount. It is true that it has raised significant sums in the latest investment rounds, but the company is a money burning machine. Arab money and debt as exits. As the aforementioned Siegler article reveals, an important part of that investment may come from the United Arab Emirates through MGX, the investment fund. Another option is to resort to debt, which has already been very common in SoftBank’s investments (they have 150,000 million invested with that formula). Meanwhile, OpenAI looks for other girlfriends (Oracle). The project is also revealing other parallel movements. In The Wall Street Journal They highlight how OpenAI is beginning to look for options for its alliance with Microsoft, something that both have admitted. At OpenAI they complain that Microsoft does not give them the computing power they need, and they seem to be testing alternatives like Google. Perhaps Oracle is also among the candidates, especially now that it will be one of the participants (along with NVIDIA) in the creation of the large data center in Texas. It seems clear that OpenAI wants to not depend so much on Microsoft (or anyone) and Stargate may be a vehicle to achieve this.
