It has been frozen for 30 years at 8,500 meters. Now a mission wants to finally solve who was the most famous corpse on Everest

by

If you like mountains and have ever gone (or fantasize about going) to Everest, surely the name of Green Boots sounds familiar: it is a reminder that climbing the highest mountain in the world is still a risky activity. The body of this mountaineer who died in the middle of the ascent was mummified at the entrance to a cave that you have to pass through when you climb the main ascent route from the Tibetan side. 30 years after his death, The Guardian echoes a leaked document where the rescue operation and repatriation of Green Boots to India is collected. In the rescue process it would also correct a mistake that has lasted three decades: the identity of the corpse would be cleared once and for all. The tragic story of Green Boots. “Green Boots” is the nickname of the mountaineer found in 1996 under a rocky outcropping at 8,500 meters above sea level, just 350 meters from the summit on the northeast route that ascends from the Tibetan side. The nickname has little originality: he was wearing boots of the same brand and model Koflach Arctis Expe phosphor green in color. His boots (and his body) were exposed and since it is in a transit area, it has become a macabre reference point to inform the base when they reach that position. Who really is Green Boots?. As for his identity, for almost 30 years it was assumed without official confirmation that It was Tsewang Paljoran Indian mountaineer who died in a severe snow storm known as the 1996 Everest disasterwhich killed 12 people. That tragedy inspired the book Into Thin Air. However, as reported by The Guardian, the document from the Indian rescue authorities identifies the body as Dorje Morupan Indian guard member of a Indo-Tibetan Border Police expedition who died in that same tragedy. The document ensures that this identification “has been confirmed through a prior verification process within the framework of a prior technical evaluation”, although without detailing what it consisted of. The recovery mission. The rescue bidding document asks companies to bid for the mission, which must have at least six Sherpas who have previous climbing experience. In addition, they must provide evidence of the mission and transport the body to Delhi before October. As explains Alan Arnettean American mountaineer and well-known blogger about Everest, lowering it is going to be “an arduous task” and estimates the operation at about $150,000. The monsoon rains also work against it. According to Sherpa Tshiring Jangbu details to The Guardianfounder of Everest Sherpa Expedition and with experience in this type of operations, with only a third of the oxygen available compared to that at sea level, activity above 8000 meters requires enormous effort and decision making can become more difficult. And that’s not to mention the load: a frozen body with mountain equipment can weigh up to 200 kilos. In addition, limbs frozen at angles impossible for descent sometimes mean they have to resort to amputation. A cemetery called Everest. Precisely because of the difficulty, danger and cost of the rescue operation, approximately 200 bodies still remain there on the slopes of Everest. As New Zealander Guy Cotter, who coordinated a similar rescue operation with his company Adventure Consultants in 1997, explains: “For families, recovering a body from the mountain gives them comfort, as long as it does not put other people at undue risk.” And according to their experience, there have been cases of recovery of bodies in which more people have died. Aware of the risk of their hobby, there are experienced climbers who wish that, if they die while climbing, their remains remain on the mountain, but are moved out of sight. Of course, families do not always think alike. In Xataka | Climbing Everest in person costs 50,000 euros.

The Medici have been carrying an apparently unsolvable mystery since the 16th century. Science finally has an answer

by

The uncle of a famous superhero said that ‘with great power comes great responsibility’. If what we are talking about is the Medici, the saga of bankers, prelates, patrons and rulers who dominated Tuscany between the 15th and 18th centuries, great power entailed something else… enormous risk. One filled with rivalries and plots that could come from both external enemies and the family itself. Hence the chroniclers carry four centuries wondering why some of its main figures died suddenly at the end of the 16th century. Disease? Bad luck? Murder by poisoning? Science already has an answer. Worthy of Agatha Christie. The British queen of suspense left us exciting novels, but few match the Medici family chronicle in mysteries and script twists. It takes reviewing some of the events that shook the Florentine saga in the second half of the 16th century to prove it. In 1562 the cardinal Giovanni de Medici He died at the age of 19 after a trip along the coast accompanied by his mother, Eleonora and his little brother Garzia, who also died around the same time. Only 25 years later the drama hit the family again through his brother, the Grand Duke Francesco I. He died in 1587, aged 46. Just a few hours later his wife did it Bianca. Quite a coincidence, right? That is what they thought the contemporaries of Francesco and Bianca, who in a matter of 24 hours watched the two members of one of the most powerful couples in the region go to their graves. In theory the cause of death was malaria, but… Wasn’t it a coincidence that husband and wife died just a few hours apart? Wasn’t it suspicious that exactly the same thing had happened to them as had happened to Giovanni 25 years earlier? Rumors of murder arose and eyes soon turned to Ferdinandanother Medici. The Tuscans of the time cannot be blamed for their suspicion. Ferdinando was next in the line of succession and risked being overtaken on the right by his nephew, the illegitimate son of Francesco I. As if that were not enough to spark rumors, they say that he had visited the Grand Duke and his wife shortly before the couple fell ill. How long does a suspicion last? Well, more than four centuries, which is how long historians have been turning around Francesco’s story. Why did he die in such a sudden and premature manner? Was it malaria? Arsenic poisoning perhaps? Did Ferdinando plot against them? Science tried to solve the mystery a long time ago, but it has only added fuel to the fire. At the time, the analysis of exhumed bone remains confirmed the malaria theory; but other studies, including one from 2006 carried out by professors and forensic experts from Italy and based on toxicological examinations, pointed to poisoning. An impossible labyrinth. The testimonies of the time do not help either. We know that Francesco and Bianca showed symptoms compatible with malaria and that the Medici family doctors tried to cure them with bloodletting, a method with which they surely (now we understand) only made things worse. The problem is that supporters of the poisoning theory also have their own arguments. Donatella Lippi, one of the authors of the 2006 study, remember that although it is confirmed that the couple contracted malaria, it does not mean that that was the cause of death. It even slips that in the Vatican Library there are testimonies that speak of skin rashes and other symptoms that could well be related to arsenic poisoning. And the genetic analysis arrived. This is how things were until a few weeks ago, when a group of researchers from the University of Pisa and Yale published a new study in iScience in which they collect their conclusions after subjecting bone remains of two members of the Medici family to DNA analysis: Giovanni, who died in 1562, and Francesco, who followed him to the tomb 25 years later. To be more precise, the researchers extracted genetic material from four rib samples, three from the duke and one from the cardinal. His remains and those of other Medici rest in mausoleums located in the Basilica of San LorenzoFlorence. Go one step further. In the past, researchers had already tried to clear up the mystery with paleo-immunological analyzes that, although they yielded some interesting conclusions, did not serve to silence “the rumors.” as you recognize Valentina Ciuffra, professor of History of Medicine at the University of Pisa and one of the authors of the study published in iScience. It was necessary to go one step further. And that is precisely what the Pisa and Yale team intended by using advanced methods to study ancient DNAgenetic material extracted from samples that are centuries and centuries old. What have they found out? That both Giovanni and his brother Francesco suffered from malaria. We know this because researchers located traces of Pasmodiumthe parasitic protozoa that cause the disease. One of the two Medici brothers even suffered it in a particularly bloody way: both the bones of the cardinal and the Grand Duke preserved traces of Pasmodium faciparumthe most lethal species among humans; but in the case of the latter (Francesco) greater molecular traces of P. malarie. What does that mean? That the Grand Duke who died in October 1587 showed traces of two species of malaria. It is not something exceptional. Experts have already detected samples in Belgium that suggest the coexistence of several species of malaria, although they insist that further research is necessary before stating with complete certainty that both species circulated in 16th century Italy. “With scientific certainty”. For the authors of the new DNA study, their work is conclusive and settles a 400-year-old mystery: “This genetic analysis confirms historical accounts, as well as previous research. We can now affirm with scientific certainty that malaria, and not poisoning, was the cause of the death of Grand Duke Francesco de’ Medici,” stands out Valentina Giuffra. In case there … Read more

The Don Quixote that Orson Welles never finished will finally take shape. Four film libraries have had to agree to achieve this

by

It took Welles almost thirty years to finish Don Quixote. It took Terry Gilliam another thirty and he got it, but the process was a nightmare that deserved its own documentary. Adapting Don Quixote has given us several minor classics and some other milestones (the historic Spanish animated series, without going any further) and now, four European film libraries are about to demonstrate that there is a third way, through the recovery and restoration of one of the most famous non-films in history. International collaboration. Four film institutions have decided to finish, to the extent that something like that can be finished, the work that Orson Welles left unfinished after his death. During the Cinema Ritrovato festival in Bologna, the Spanish Film Archive, the Cinémathèque Française, the Italian Cineteca Nazionale and the Filmmuseum in Munich They confirmed the beginning of the reconstruction of their ‘Don Quixote’. The project is coordinated by Esteve Riambau, historian, filmmaker and former director of the Filmoteca de Catalunya. The objective, as explained by Riambau himselfis to have the reconstruction ready in 2028. An infinite shoot. In 1957, Welles’ friend Frank Sinatra invested $25,000 in the project. The original idea It was to function as a complement to the singer’s own television show, in the form of a short special for CBS. At that time it was scheduled to star Charlton Heston, but it couldn’t be due to scheduling issues. Filming took place in Mexico, Spain and Italy and lasted, with interruptions and returns, over almost three decades. The agreement with CBS ended up falling apart and Welles decided to turn the television special into the feature film that would never be finished and that would evolve bathed in pure chaos: in Mexico, for example, Welles worked without a finished script, filming improvised sequences in the street, and he himself was in charge of keeping track of the filming with obsessive detail. Neither the death in 1969 of the actor who played Don Quixote, Francisco Reiguera, nor that of the actor who played Sancho Panza, Akim Tamiroff, in 1972, stopped Welles, who also continued filming in color. In 1982, three years before he died, he was still making changes to a film he affectionately called My baby. A curse that spreads. Don Quixote has a reputation for devouring races. Terry Gilliam needed eight failed filming attempts and a lawsuit from his own producer to carry out ‘The Man Who Killed Don Quixote’, a project that started in 1998 and finally premiered in 2018. The disaster of the first attempt, in 2000, with Jean Rochefort and Johnny Depp, was portrayed in the documentary ‘Lost in La Mancha’. Before them, Peter O’Toole, John Lithgow and Rafael Rivelles had already given life to the gentleman in much more conventional versions. What material do we have? A huge and dispersed amount. The Cinémathèque Française preserves about 80 minutes in 35 mm positives that were exhibited at the 1986 Cannes Festival. The Spanish Film Archive bought 16 and 35 mm rolls in 1991, totaling 50,000 meters of film, in addition to the cultural exploitation rights, and is the researcher of the entire legacy. The partially unpublished block is in Rome: between 40,000 and 50,000 meters of negatives that the editor Mauro Bonanni kept in Cinecittà and that Oja Kodar, Welles’s last collaborator, recovered in 2017 after settling a dispute with the editor. What’s coming Riambau affirms that all these materials “no one has seen yet.” Added to that are more than 2,000 pages of script that Welles wrote over decades, although some of the material has been lost. Riambau will order a script that does not yet have a clear structure and in 2027 it will be compared with the images to census all the available material. There may be surprises on the thousands of meters coming from Cinecittà: this Quixote can still cause more headaches.

Finally, Toledo has its transportation app. It only took a decade of digital stumbles and analog queues

by

Yurni is the new official application of urban transportation in Toledo. It has just been presented by the city council and goes hand in hand with the Ruiz Group with a concrete promise. If you search for them in the Google Play Store or the Apple store and you read “Yurni Linares” it is because, in fact, the application began offering service in the town of Jaén. Now it arrives at the mecca of Corpus Christi with the intention of resolving past problems, putting an end to COPI’s ordeal, allowing the card to be recharged from the mobile phone and offering reliable schedules in real time. Third time’s the charm. Yurni arrives with functions that should be obvious in 2026: consult real time and theoretical arrival time, plan routes according to transfers and duration, recharge entitlements, buy QR tickets and manage a virtual wallet without having to type the card number each time. In fact, the idea of ​​the service is to integrate recharging along with metrics such as calories burned or CO₂ saved on each trip. Before the launch, about 150 people tested it—including ONCE users—and the average rating rose from 4.5 out of ten for the previous app to 7.9, a sign that at least the interface and stability are no longer the recurring joke at the stop. Because there were days where not a single marquee met the estimate. It is estimated between 80,000 and 90,000 downloads. From ‘Toledo Bus’ to COPI. Yurni started in 2017, when GMV developed the Bus Toledo app for Unauto and the City Council, integrated into the Operation Assistance System. It was, de facto, the one used by any Toledoan who did not opt ​​for Google Maps or Apple Maps. Taking advantage of the onboard GPS and information panels at stops, the application worked at times. The City Council insists that this time the tool has been “validated by users.” So “I don’t know when the bus passes” should now be resolved with a glance which, in the process, corrects the trend of ghost schedules and poorly communicated incidents that led to constant complaints, whether you were waiting in Zocodover, in the Santa María de Benquerencia industrial estate, coming from Azucaica or waiting on the Paseo de la Rosa in Santa Bárbara. New urban offer. In 2024, the city launched COPI Toledo, developed by Vanwardia in collaboration with Unauto and Grupo Ruizpresented as a comprehensive urban mobility solution with real-time information and plans to integrate other modes of transportation on a single platform. And how does it work? Like almost all of them: as soon as you open the app it is linked to a phone number – although you can use it without login -, you receive an SMS and an associated account is created. You can ask it to launch alerts for route and schedule changes and the application will ask for geolocation permissions to recommend closer stops. The rest is as simple as entering the destination and receiving an estimated arrival time. Toledo grows; its roads, no. Toledo has been suffering from worrying traffic congestion for years. In addition to the constant works in the town, there have been blockages in the roundabouts attached to the new University Hospital, delaying the arrival of students to their homes by up to an hour every midday. But the numbers are clear: during 2025, Toledo set historic figures of more than 1.6 million overnight stays and almost 1 million travelers in the first eleven months, beating 2024 which was already a record year in itself. Toledo is, in addition to the fifth Spanish province where tourism is growing the most, a city on the rise: 86,070 inhabitants as of January 1, 2023 at almost 100,000 currentwith a certain concentration in usually more unpopulated areas—Valparaíso, La Legua and Los Cigarrales de Vistahermosa—. However, the diagnosis of the Sustainable Urban Mobility Plan indicated that only 7% of internal journeys in Toledo city are made by urban bus, which promotes congestion. The mismatch between supply and demand is estimated as the main cause. The most serious shortcomings occur in the industrial estate, Vía Tarpeya and peripheral urbanizations such as San Bernardo, where you have to walk several kilometers to reach an urban stop. Very irregular management. During the last two years, local media They have documented general dissatisfaction with the poor functioning of the app. The Unauto manager acknowledged that they had rushed the launch, forcing them to update the app just three months later to make the schedules more visible. In December 202025, a server outage left both the application and the card recharge website out of service, forcing us to return to the physical ticket or payment on board with a bank card. In that cycle of technological promises, the nominative cards experienced their own battle of Las Navas de Tolosa: at the beginning of 2026, the local government of PP and Vox decided to maintain the bonus of the 40% on the ticket only for registered votersforcing the creation of a special card for them, while the rest were left with the state’s 20%. The bus pass for those not registered rose from 0.38 to 0.51 euros per trip and the general monthly payment went from 20.40 to 27.20 euros, with the explicit message that aid should be concentrated on “the neighbors.” Unexpected consequences. For example, it is no longer possible to tick for someone else. Because in addition to requesting copies of the DNI and, in the case of minors, family books or other documents, photos have been requested that have never been inserted into the new cards. FACUA described the process as “illegal and abusive” due to the transfer of data to a private company. And, after the complaint, the City Council and the dealership rectified allowing the form and sending by email, but thousands of people still had to go through the small Unauto office, collapsing it right in the middle of the operation after Easter.

Cancer in people under 50 years of age has been growing for decades. A macro study finally points to the big culprit: biological aging

by

The increasing incidence of cancer in young adults is one of the most debated topics in recent oncology. In recent years, exhaustive reviews have warned of an increase in diagnoses in those under 50 years of agealthough medical science had long been searching for the underlying mechanism that connects the dots between modern lifestyle and the early onset of this hated disease. The answer. A new study recently published seems to have found a key piece of the puzzle, which is nothing more than that our cells are aging faster than our ID card. This is the conclusion of research published in the journal Nature that indicates that accelerated biological aging is associated with a greater risk of developing early-onset cancers, especially solid cancers such as lung, stomach and also uterine cancer. Two concepts. To understand the finding, we must first differentiate between chronological age and biological age. The first of these is immovable, since it is nothing more than the years that have passed since our birth. But biological age is flexible, since it is calculated by evaluating the physiological state of a person through blood biomarkers and metabolic profiles. It reflects how “old” our tissues and organs really are. How to measure them. To measure this, Tian’s team used models already consolidated in scientific literaturesuch as PhenoAge and the Klemera-Doubal method. With these tools, they crossed the data of more than 150,000 adults from the UK Biobank and approximately 10,000 program participants. All of Us of the United States. The result shows a dangerous imbalance. This means that those people born in more recent decades had a greater tendency to have a biological age higher than that corresponding to their date of birth. And this time “jump” has direct clinical consequences such as the appearance of cancer. To be more specific, it has been seen that every time we have a person with a biological age higher than their corresponding age, they have an 8% higher risk of having early-onset solid cancer before the age of 50. If we compare the extremes, individuals located in the tertile with the greatest biological aging have a 15% greater risk of developing the disease compared to those in the tertile with the least biological wear and tear. The context. The main thing is not to fall into alarmism, since, although it is true that cancer is increasing in the youngest people in society, it is also increasing in all remaining bands due to multiple factors such as general population aging and better screening methods that allow us to detect cancer earlier. However, the specific data on early onset are undeniable, since large studies point to significant increases in thyroid, breast, colon, kidney and endometrial tumors in the 20 to 49 age group. Colorectal cancer, specifically, is the one that worries the most due to its escalation in young adults. The lifestyle. That we are biologically aging much faster than we should is not magic, but rather it seems to be influenced by different factors related to lifestyle. These include rates of youth obesity, prolonged consumption of diets rich in ultra-processed foods, a sedentary lifestyle, and exposure to environmental toxins. What this new work provides is the quantification of the damage, since these risk factors accelerate the biological clock. We must keep in mind that the human body is exposed to pro-inflammatory factors for more years from early stages of life, which makes it easier for DNA damage to accumulate faster than cellular mechanisms can repair it.

We’ve spent years unraveling a signal from space that shouldn’t exist. And finally we have a “Rosetta stone” to decipher it

by

It was the year 2018 when a team of Australian scientists detected a strange radio signal in the plane of the Milky Way. The radio pulse was too slow for any known astronomical object. It seemed more like some kind of anomaly or error in the telescopes than a new discovery. However, in 2025 another similar signal was located. And then another and another. Currently, there are at least 12 of these signals recorded, which have been named long-period radio transients (LPTs). Each of them includes a new feature that makes it impossible to find a common thread. Or at least it had been that way until now, since a new group of Australian researchers has located a sign that brings together several of the pieces of the puzzle. It has been so useful that it has been colloquially dubbed a space Rosetta stone. All the pieces together. The signal located in 2018 (although it was published in 2022) occurred every 18.18 minutes. With this periodicity, a star in the Milky Way increased its brightness for 30-60 seconds, and then decreased it again. Later a similar phenomenon was located, in which it was possible to see further. A binary system consisting of a white dwarf and a red dwarf was identified. The interaction between the two produced the emission of radio waves. However, when another LPT was detected, the emissions were not radio waves, but X-rays. How was a single phenomenon going to be defined if each one was different from the previous one? The key, finally, has been another LPT, initially located by the ASKAP telescope, of the Commonwealth Scientific and Industrial Research Organization (CSIRO). With it, and with the collaboration of other telescopes, a binary system composed of a white dwarf and a red dwarf has been identified, whose interaction gives rise to a periodic change in brightness, accompanied by the emission of radio waves and X-rays. All in one. With all the pieces, it has now been possible to reconstruct the event. Four telescopes to reconstruct history. The new LPT has been named ASKAP J1745-5051. It is not possible to know exactly how far away it is, although estimates place it between 1,300 and 30,000 light years away. Observations made with the ASKAP radio telescope made it possible to locate a periodic emission of radio waves every 81 minutes, which corresponded to a possible LPT. In order to check if the rest of the conditions that had been observed individually were met, it was observed with three other telescopes. On the one hand, space telescopes Swift and Einstein Probewith which X-ray emissions were detected. On the other hand, with the Southern Astrophysical Research Telescope (SOAR). With this, a binary system composed of a white dwarf and a red dwarf that orbit each other with a period of 81 minutes was identified. Everything fits. The full story. The conclusion when putting all the pieces together is the following. On each orbit, the white dwarf, which has a large mass concentrated in very little space, gravitationally attracts the red dwarf and extracts material from it. This is channeled by the magnetic field of the white dwarf itself until it reaches its surface, where it collides, producing a temperature increase of millions of degrees Celsius. Furthermore, this very violent interaction causes the release of energy in the form of X-rays. On the other hand, the gas accelerated by the colliding magnetic fields of both stars is what appears to produce the radio signals. A Rosetta Stone. The principal investigator of this new study It’s called Kovi Rose. We might think that this has had to do with the fact that the discovery is referred to as a space Rosetta stone. And maybe it has had a little influence, but the reality is that there are more reasons. The original Rosetta stone It was a fragment of Egyptian rock in which there was a text written in three different languages: ancient Greek, hieroglyphics and demotic writing. Because archaeologists of the time knew how to speak Greek, they were able to use it as a basis for understanding hieroglyphs. One language allowed them to reconstruct another. In this case, the new discovery is also in three languages: radio waves, detected by ASKAP, X-rays, with which Swift and Einstein Probe work, and visible light from SOAR. Three languages, three pieces that, when read together, can help to understand the whole much better. With this Rosetta stone, the authors of the study hope to be able to unravel many of these mysterious signals from the Universe.

The time since 1940 has changed a lot. We finally have a time machine to see it on an interactive map

by

I was born on a Monday in September at noon and, obeying the tradition of the San Miguel summer, the weather was mild and sunny even though October was just around the corner. I know this because my mother has told me a lot of times, but today I also just confirmed it. And be careful, finding out the weather of a day in the 80s was not a priori as easy as knowing what it was last year: it normally involved resorting to scientific databases or finding paper records, which are already old. The good news is that there is a free tool, accessible from any browser and moderately intuitive so that anyone can know what the weather was like on any day (and any time!) from today until 1940, from your date of birth to your wedding or a trip. The not so good news is that it is the best test to see how time is changing due to climate change. His name is Weather Replay and in a few words it works like a meteorological time machine in the form of a weather visualization web application. Behind this website there are two top-level European projects: on the one hand Copernicus Climate Change Serviceintegrated into the EU space program and with the aim of offering rigorous climate data available to everyone. On the other hand, ECMWF, the European Center for Medium-Range Weather Forecasting, the world reference body for numerical weather prediction. Weather Replay Home Screen The climate time machine starts in 1940 The first screen says roughly what it does: you choose a date and time, use the box at the bottom left to write a location and from there you can see a 48-hour animation where the atmospheric conditions of that specific moment are reproduced: temperature, wind, precipitation, pressure and a few other variables. Everything is very visual and available in a few seconds, without installing anything or registering. Layers are a key element to learn more information. Weather Replay Although there is an initial tutorial that may be interesting to follow, the buttons and their function and the legend are easy to understand and despite its simple appearance, it is quite powerful and with practical options to only have what interests us such as zooming, modifying colors and levels or layers. An especially interesting function is being able to compare the time on two specific dates. Swipe left and right to see what the weather was like on two days from 1940 to today. Weather Replay Under the hood of this comprehensive interactive map is ERA5, the ECMWF global atmospheric reanalysis that continuously reconstructs the state of the atmosphere using real data from satellites, sounding balloons, ocean buoys and weather stations with high-resolution numerical models. Thus, it covers the entire Earth with a mesh of about 31 kilometers and 137 vertical layers up to 80 kilometers in altitude. Despite the huge amount of data it handles, the simulations and management are agile thanks to the fact that it is in the cloud DANA Floods of 2024. Weather Replay Beyond tinkering and satisfying curiosity, this tool means that anyone has access to 80 years of atmospheric data in an intuitive and graphic way to see with your own eyes how phenomena have evolved such as heat waves, extreme rain events or wind patterns in the regions you know best. In short: that everyone can see climate change. At a teaching or journalistic level, it constitutes a magnificent resource to contextualize meteorology. For example, reproducing how the tragic Valencia DANA of 2024 began.

The iPhone 17 finally drops in price. New historical low for very few days

by

Apple mobile phones are going through a very particular situation, and that is that in addition to the lack of stock that they have had since their launch eight months ago (especially the base model), the offers have been very brief with very unattractive discounts. However, MediaMarkt is celebrating its new Apple Days right now and it is precisely the iPhone 17 who stars in the campaign with a historic minimum price. If you were thinking of buying the mobile, now you can do it for 899 euros. Of course, the offer will end along with the campaign on May 28 at 9:00 a.m. The price could vary. We earn commission from these links The iPhone 17 at an all-time low price He iPhone 17whose official and recommended price is 959 euros, has received very few offers since its launch. The stock has also been very irregular, preventing, for example, buying it in some stores for a while. However, right now there is sufficient stock in the MediaMarkt online store, allowing it to be purchased at this new price in its five different colors. This mobile phone is the one that has benefited the most from the generational leap, since it is the one that has changed the most compared to the iPhone 16. We find a very good screen both for its quality and for its 6.3-inch format, but above all because it now has the 120Hz refresh rate that until its launch we only saw in the most expensive Apple phones. Another of the great news is that Apple has finally started manufacturing its mobile phones with a 256 GB minimum configuration internal storage, a larger number to store information locally. In addition, it is also worth mentioning that the iPhone 17 incorporates the A19 chip and that it has wireless charging through MagSafeone of the most useful technologies in Apple phones. ⚡ IN SUMMARY: iPhone 17 offer today ✅ THE BEST The arrival of 120 Hz: Until its launch, we only saw this refresh rate in the most expensive Apple models. Increasing base internal storage: Apple has finally abandoned the minimum configuration of 128 GB. ❌ THE WORST It gets too hot: something that happens especially during long gaming sessions or with intensive use. Its fast charging: It improves generation after generation, but it is not up to par with the competition, which has much cheaper mobile phones with greater fast charging. 💡 BUY IT IF… You are looking for the best quality-price ratio within Apple’s current generation, if you are coming from Android phones and want an iPhone with a 120 Hz refresh rate and you are also looking for a model that is compact. ⛔ DON’T BUY IT IF… The 256 GB of storage is not enough because you usually take a lot of photos (and in good quality) or if you are looking for a cheaper iPhone, like the iPhone 17e.

Throughout its more than 4,500 years of history, the Great Pyramid of Gizathe tomb of Pharaoh Cheops, has witnessed the rise and fall of empires, the erosion of the desert and also the earthquakes in an area with very intense seismic activity. This is crucial, because while the Alexandria Lighthouse or the Colossus of Rhodes succumbed to the Earth’s tremors, the 138-meter-high mass has remained immovable. The secrets Their longevity has been a topic of conversation for decades among Egyptologists, engineers and architects who tried to understand why they were still standing. And it is logical, because every physical object has a “natural frequency” of vibration, and this is crucial because when the seismic waves of an earthquake coincide with the frequency of an object, a very important amplification effect is produced. It is an effect that we can see, for example, on a swing, since we push it at the exact moment so that it goes higher and higher. And this is where the “superpower” of the Great Pyramid lies. What does it consist of? According to a study published in Scientific Reports, the pyramid and the ground on which it sits dance to completely different rhythms. This means that the pyramid has a natural vibration frequency which is around 2.3 Hz. For its part, the surrounding terrain of the Giza Plateau vibrates at a drastically lower frequency, close to 0.6 Hz. This mathematical gap is a true structural lifesaver, since, since there is no coincidence between the frequency of the stone mass and that of the ground during a seismic event, resonance is practically impossible. Waves from the earthquake pass through the area, but the pyramid does not amplify the vibration, dispelling the danger of a catastrophic collapse. It is, in modern terms, perfect passive seismic isolation behavior. Extreme geometry. This frequency decoupling is one part of the equation, since the focus is also on the impeccable architectural design and geometric of construction, which provides a uniform structural response to any mechanical stress. All this is thanks to the ingenuity of Egyptian engineers who created an artificial monolith that defies the laws of destruction through several characteristics, such as greatly lowering the center of gravity. And, unlike modern structures that are slender, in pyramids the vast majority of stones are concentrated in their lower third. This makes the building virtually impossible to overturn, regardless of the violence of the transverse shaking. More reasons. The square pyramid shape is not just an aesthetic or religious choice, but it is the most stable geometric figure that exists to withstand compression. Symmetry ensures that when seismic waves shake the building, the load and stress are distributed equally across all faces, avoiding critical fracture points. The internal chambers. One of the details that the investigation has pointed out is the unsuspected role of the famous internal chambers of the pyramidlike the King’s Chamber. Historically, they have been analyzed from a funerary perspective, but it is now suggested that, together with the impressive granite discharge blocks, they also act as a system to dissipate energy. In this way, seismic waves that manage to penetrate the structure encounter abrupt changes in the density of the matter, which causes the waves to refract and disperse. Did they do it on purpose? This is the question we can ask ourselves after reading all this, and the most plausible answer is that the Egyptians did not handle all these technical concepts, but they were absolute masters of empirical engineering. Through observation, trial, error and a deep knowledge of the materials, they arrived at the optimal solution so that they would last for life. They built for eternity based on massive stability and, in doing so, accidentally designed a building that meets the same safety parameters that we demand of our most critical infrastructure today to prevent them from collapsing in an earthquake.

Without gas stations in space we will not reach Mars. NASA knows this and is finally doing something about it

by

Much of a spacecraft’s fuel is consumed in maneuvers to leave Earth’s orbit. For this reason, as manned missions move further away from our planet, we must begin to think about use space gas stations. These are not fuel pumps floating in space, but satellites, or even ships, capable of transferring fuel to a ship that needs it to travel further. At the moment, this is one of the weak points of many missions, so it is important to start working on technologies that allow it. At NASA they are very aware of this problem, hence this year they are going to launch LOXSATa mission that will test 11 different technologies to guarantee the transfer of propellants. 9 months ahead. LOXSAT is a NASA mission in collaboration with the company Eta Space. The objective of this mission is to test different cryogenic fluid management technologies so that in the future propellant tanks can be created in space. The mission will remain in low Earth orbit for 9 months. Meanwhile, 11 technologies will be tested focused on achieving four objectives: reducing boiling, improving propellant transfer, maintaining stable pressure and measuring propellant levels. The big problem. Cryogenic propellants, such as liquid oxygen at extremely low temperatures, are very efficient, but they have a major disadvantage. And in microgravity conditions, when the transfer between ships is carried out, the temperature cannot be kept low enough, so the fuel boils and suddenly transforms into gas. This causes a huge increase in pressure, which can endanger the ships involved. It seems to be that precisely this problem is the one that is giving SpaceX the most headaches. Like Blue Origin, this company must demonstrate its ability to refuel in space to be part of the Artemis missions, but it is not being easy. This is the reason why with LOXSAT methods will be tested to maintain stable pressure and reduce boiling. Space gas stations. The objective of this mission is to perfect the technology so that in the future there can be fixed propellant tanks in space. In other words, they hope that as we colonize space terrain we have gas stations so as not to run out of fuel. China on the heels. Ideally, in the future, large ships could exchange propellant. No space agency has achieved anything like this. However, China has indeed achieved it with satellites, in their Shijian missions. Plus, they did it in a higher orbit, so they are ahead of NASA in the particular race that has been uniting them for so long. Of course, at the moment, China has not tested cryogenic propellants, but tried hydrazine replenishment. There is still room for improvement. Write down the date. The mission will depart aboard an Electron rocket from Rocket Lab. The launch will be in the summer, no earlier than July 17, from New Zealand.
