In 2011 a mysterious series of numbers and letters appeared in Reddit. Thousands of people would spend years trying to decipher her

by

Fourteen years ago a Reddit user appeared called ‘A858DE45F56D9BC9’ and began publishing characters of characters, apparently meaningless, in a SubnetDit of the same name. For more than a year the publications went unnoticed until one day madness began. What followed was the creation of a community with thousands of obsessed people with solving the puzzle And, above all, know who was behind the one who is considered One of the biggest Internet mysteries. Reddit’s Stonehenge Although the user’s name was much longer, in Reddit it is known as The mystery of A858. Although the first publications arose in July 2011, it was not until 2012 when the Reddit community began to pay them attention. Some users attempted to disappoint the messages and there was one that made interest explode. The comment and the answer confirmed that A858 was not “something”, but “someone.” A user mentioned that A858 was Reddit’s Stonehenge in reference to Its function was a mystery. A858 responded shortly after with one of his classic encrypted messages. The surprise came when they discovered that it was an image in ASCII format that represented precisely that: the Stonehenge. Until that point he had not given too much importance, but with this it was demonstrated that Behind A858 there was someone human. And then madness unleashed. Years trying to solve it Users wanted to know the goal behind those messages and set out to disregard them, but they soon realized that it was not going to be simple. In September 2012, the SOLVINGA COMMUNITY858 which currently has 15,000 members. Here a collective effort to understand The goal behind A858 that lasted years. Decipher A858 seemed impossible. He also behaved strangely: he disappeared, erased posts … the community was frustrated Only a few messages were deciphered by the community, including some citations of famous authors such as is from Max Lerner, Christmas greetings either References to April’s Fool (The equivalent of innocent’s day). The challenge was very complex from the technical point of viewhe used unusual obfuscation techniques, and there was not a clear pattern in his behavior; Sometimes he disappeared, he deleted posts, the submandit made deprived, Some messages were very easy to solve and others seemed impossible… This made the community frustrate and begin to lose interest, but then A858 appeared and everything was reactivated. Ask A858 Anything One of the points in the Subbreddit Solvinga858 was in 2015 when A858 made a mist (Ask Me Anything) where He attended to the numerous doubts of the users, although they also had to disappoint them. It wasn’t going to be so simple. Users asked him if they were wasting his time trying to decipher him, to which A858 replied that no, but I couldn’t tell them the goal behind the project. He also revealed that only a woman from the United Kingdom had managed to decipher him and expected more correct answers. Here you can read in fullbut then we highlight some of the questions and answers of the session: What is R/A858DE45F56D9BC9? The objective cannot be revealed. A858 published ASCII art drawings, prime numbers tables, Apple II source code fragments, etc. Were you playing with us? Because? Coded posts are designed to be easily resolved. And the other encrypted using a stronger encryption? The other posts are not designed to be easily resolved. There are often long pauses in which there are no A858 posts. Is A858 your only job? Sometimes we are retouching. Other times we are working on other projects. Are you doing this love alone or are we talking to the team of which you are part? A858 is a project with a team. I am a member of the team. Are you affiliated with a government organization? I don’t know any place that has no government. An unsolved mystery The question session fed even more if the mystery fits, but over time A858 was publishing less frequently until the publications ceased completely. In March 2016, after months in which the Subbreddit had been deprived, A message appeared which said “the A858 project has concluded. It can be unsubscribed.” Many users did not believe it, but A858 never published again. A858 was never resolved. We only know that there was a company behind that one day cut the financing. The next news that was had was In September 2016 through one of the moderators of Solvinga858which revealed that he had had contact with the person behind A858. In his message he assured that this mysterious person was paid by a company to “post code puzzles through encryption and different text handling methods.” After a while, The company behind the project decided to cut the financing And there all ended. Needless to say that It was not the answer that the community expected and left too many unknowns to solve. Theories behind A858 As a good mystery, there are many theories about what was really behind A858. One of the most repeated is that it was A company looking for experts in encryption To hire them. A858 agreed over time with Cicada 3301 Another very similar mystery, although much easier to solve. Supposedly those who managed to decipher Cicada, received a message to enter a mysterious organization. Another of the theories defends that A858 a ‘Numbers Station’ Used by Mossad for Espionage Tasks. It does not seem to be known with total certainty, but one of the theories that makes more sense is that A858 was A company testing its own safety. In this scenario, The objective of the project would be precisely for anyone to solve the puzzleswhich would show that security was good. If so, they got it.

The mythical An-124 had been trapped for years and now it flies again

by

Inheritance of the Soviet UnionUkraine has both larger aircraft in the world (If we don’t count the monstrous Stratolaunchclear). Or had. On the one hand, a beast with wings called Antonov AN-225a unique model in the world that had a large load capacity and that could carry spacecraft on its back. On the other hand, the Antonov An-124, another somewhat smaller load model. With the Start of the Ukraine Warboth were trapped. Now the AN-124 sets the skies again, and it is much more than to see this giant fly again. Soviet monsters. In the context of the Cold warone of the battles was that of “I”. The United States flew for the first time in 1968 the imposing Lockheed C-5 Galaxy For transport of troops, becoming the new largest plane in the world. The Soviet Union was not going to stay with a crossed arms and began working in its replica. Thus, two companies (Aviastar-SP at Uliánovsk, Russia, and Aviant in Kyiv, Ukraine) undertook design and RPUEBAS work in parallel. The result was the AN-124, a huge cargo plane with an imposing front that is physically similar to Lockheed C-5 Galaxy, but something bigger. It was introduced in 1986 and, just two years later, the AN-225 Mriya appeared. Aviant Fruit (current Antonov) a larger version, with six engines and with a wingspan that prevented him from landing in 65% of airports around the world. After all, although it was a cargo plane, it was focused on transporting the Soviet transforder Burán and any other element of the Soviet space program. See this live must have been impressive Antonov Airport Battle. And if I speak of Antonov AN-225 in the past it is because, with the beginning of the Ukraine War, both the AN-225 and the AN-124 with registration U-82073 were catching you in one of the Ukraine airports. Since it is logical, for security reasons, the flights were suspended and the ships were abandoned to their fate in the Hostomel airport. The AN-225 that once surprised the world, was completely shattered. At first, the plane pilot said that the ship was intact, but shortly after confirmed the destruction of it. This meant more than the destruction of an airplane because yes, the AN-225 made few missions a year (putting it in the air costs a million dollars), but it was a symbol of Ukraine. The AN-225 UR-82073. The AN-124 is not so unique because Russia has a couple of dozens, another seven and there are units owned by other countries, but the UR-82073 has become another symbol of Ukrainian resistance. In addition, it is a model Very important for the transport of goods in Europe. Also abandoned, he got what his older brother does not: survive bombings. Removing Russian ballast. The last three years, the ship was stopped and partially disassembled, but from Antonov they have been working secretly with a goal: to modernize it. These tasks began before the war with the aim of replacing the Russian key components with parts made in Ukraine and in the West. The Russian invasion He modified the plans and caught the operators with half-work, but they continued working and, just a few days ago, the AN-124-100 Ruslan, now renamed IRPIN, has re-crossed the skies. Furtive flight. Symbolic flight. With a nose that proudly shows a “Be Brave Like Irpin” -“is brave as Irpin” -,, now It has new airplane and navigation systems that meet the current standards. IRPIN is a Ukrainian city located west of Kyiv that played a relevant role At the beginning of the war and on July 11, the plane furrowed the Ukrainian sky with the transponder off until crossing Poland. He Transpose It is a piece that gives real-time information about the ship as its location and altitude, and everything indicates that Ukraine did not want Russia to know that the UR-82073 was again in the air. Your destiny? Leipzig, in Germany, where Antonov has its new operations base. Antonov itself shared the video of the feat a few days ago and it is they who They affirm that “the relocation of” Ruslan “was not only a technical decision, but a symbol of resilience, professionalism and unity of Ukrainian aeronautical builders. The modernized” Ruslan “will continue to fly and serve Ukraine in the international arena.” And the AN-225? Happy end to the AN-124, but … will Ukraine leave as if nothing the destruction of the AN-225? When I said there was only one AN-225, it was half truth. There was really a complete and operational, but they had one “in half” stored. As it is a practical plane, it was not considered necessary never It was completed. In July 2024, however, the situation turned a turn. David Lomdzharia, president of the state conglomerate of Defense of Ukraine, affirmed who want to rebuild the AN-225 Mriya from that second incomplete fuselage. It has been saved since the Soviet era, so the State is not known, but Antonov has saying They have already started work and cost about 500 million euros. In the end, if Ukraine reconstructs the AN-225, he would do it for more symbolic than practical reasons, but we must wait to see why there are no dates or anything on the table. At least, publicly.

150 years ago we found a lot of rivets in a funeral mound. It turned out to be Norway’s biggest Viking ship

by

From series for all ages as’Vivky the Vikingo‘o The raw’Vikings‘, movies like’THE WARRIOR Nº13‘ either ‘How to train your dragon‘And video games like’Assassin’s Creed Valhalla‘ either ‘The Banner Saga‘, the Vikings have resisted fashions and the passage of time. And one of its most recognizable elements are its ships. They continue to cause astonishment And, among all, there is one that we discover by chance and turned out to be the king of the sea viking. The Myklebust. The finding. That mysticism and that it seems that they do not go out of style, contrasts with the barely 300 years that the Viking era lasted. Speak well of his legend, and ships like the Myklebust They are an essential part of it. Centuries after his era, in 1874, archaeologist Anders Lorenge gave some strange remains on a farm west of Norway. They were inside Randehagjen funeral moundon the Myklebust farm, and among many other things, he found a lot of rivets of a ship. Unfortunately, everything in quite a bad condition because the ship was buried after being cremated, which caused him to live in the shadow of other ships such as the Gokstad or the Oseberg that were found in perfect condition. But, over the years, we have been able to train more than an idea of how this king of the seas was. Ship? Cruise. As the excavations were carried out, the researchers found more rivets until they add about 7,000. Taking into account both the amount and their size, it is estimated that the Myklebust came to measure about 30 meters. And the estimate is not only based on the rivets, but on a very specific piece of the shields of the Vikings: the Umbo. This is the central circumference of the shield, which was probably placed along the ship next to the corresponding soldier/rowing. 44 umbos were found, indicating that, at least, there would be 22 shields per side. The Vikings had several ships, but those who entered combat were mainly three. On the one hand, the Karvia small ship of about 20 meters for the expeditions near the coast. On the other, the SNEKKEa great transport of about 30 meters designed for oceanic navigation and the transport of troops. Finally, the Drakkar. The size of these varies, but the Myklebust would fit into its description as a little draft ship, numerous oars and the bow with the dragon’s head. They were the most versatile ships because they were maneuverable, but with a large load capacity of warriors. Sagastad Museum with the replica of Myklebust and its sea access ramp Cremation. Due to its dimensions, the Myklebust was a symbol of power and had to terrify to see it on the horizon if it was not of yours, and in addition to its size, it had to belong to someone high. The reason why the pieces were very damaged is because the ship was buried after being cremated. In Vikingas tombs, the complete cremation of the ship was a strange and reserved practice only to the most powerful, like a king (it is speculated with Audbjørn de los Fjordos). In addition to the trousseau, jewelry, various objects and some hunting, the deceased needed a ship for his last trip to Valhallaand the Myklebust was that last means of transport. Returning to the seas. We do not know if its owner arrived at Valhalla, but what we do know is that the Myklebust has been furrowing the Norwegian waters for a few years. In Nordfjordeid is the Sagastad Viking Centera museum and attraction focused on the dissemination of Viking culture. It has several exhibitions, but the one that attracts more looks is the Myklebust room. In it, there is one Real scale recreation And with everything of detail of the war ship that can also navigate. The work began in 2016 and ended in 2019, and each spring opens the gate of that part of the museum so that the spectacular ship is dragged a few meters until it comes into contact with the sea. It is then that he undertakes a journey through the fjords, in an event that highlights the magnificent figure of this type of ships. But that replica can fall short if objects are still discovered on the site. A 2024 analysis showed more objects in the mound, such as a bronze ring and what can be more umbos, so perhaps we would have to rethink the expanding the drakkar for future tributes.

For years we were who we called to ask for information. Now Google’s AI calls for us

by

Imagine you are looking for a hairdressing for your dog. You do not have time to call, compare prices or review reviews one by one. But Google yes. His artificial intelligence is in charge. Call for youconsult availability, ask for prices and give you the answer, all without you said a single word. That is exactly What has begun to activate Google: A new function within its search engine that allows the system to contact local businesses in your name. It is not an independent app or an isolated experiment: it appears directly in the search results, under a button that says “Have Ai Check Pricing.” An AI that acts in your name, without changing your way of searching It is not necessary to learn commands or configure anything special. Press the button, answer a series of questions and the system is responsible. Speak for us, collects data on prices and availability and returns them organized. We continue using the search engine as always, but with an AI that is no longer limited to responding: it begins to do things. An interesting point is that companies can control this function from their business profile, which guarantees that they have control over whether or not to receive this type of calls. For now, this capacity is only available in the United States. Of course, Google has not mentioned concrete plans for its deployment in the European economic space or has given dates about its arrival in other regions. If something is clear is that Google is no longer made up of offering links. He wants to execute tasks. Organize data, reason, investigate … And now also contact third parties. Google is also updating a parallel solution called Ai mode. Now it works with Gemini 2.5 Proits smartest model, and the Deep Search tool, capable of making deep searches. Both improvements are only available to those who have registered in the AI Mode experiment through Search Labs, and require a subscription to the pro or ultra plans. These novelties arrive just when the launch of Chatgpt agentsthe new openai system that operates on a virtual computer and Execute real tasksstep by step.

Some astronomers analyzed the “Big Bang sound.” Now they believe that the Earth is in a vacuum of 2,000 million light years

by

Cosmology has a huge problem. It is known as hubble tension and suggests that the nearby universe is expanding faster than the distant and primitive universe He is telling us. Something does not fit. Now, a disturbing study offers a solution. The big problem of cosmology. Hubble tension is One of the biggest headaches of modern physics. On the one hand, we have the measurements of the cosmic microwave background (CMB), the oldest light in the universe. When applying the standard cosmological model (LBDACDM), these observations show a 67.4 km/s/mpc hubble constant. On the other hand, when The expansion of the universe is measured Using nearby objects such as standard candles (a type of supernova), a significantly higher value is obtained: about 73 km/s/mpc. This difference, that the most recent data places in a tension of more than 5Sigma (a level that in particle physics is considered a discovery), refuses to disappear. A disturbing explanation. A new study Prepublished in Arxiv proposes a solution as elegant as depressing. That the discrepancy is not in our measurements, but in our location. According to Indranil Cosmologists Banik and Vasileios Kalaitzidis, we could be living in the center of a gigantic cosmic vacuum, a “bubble” of 2,000 million light years in diameter with a density 20% lower than the universal average. The test, they affirm, It is in the “Big Bang sound”. A local vacuum. The idea of the local vacuum is not new: it is known as the empty KBC (Keenan-Barger-Cowie, in honor of the astronomers who proposed the idea based on the galaxies count). If our galaxy, the Milky Way, were in a region with less matter than normal, the severity of the surrounding, densest areas, would “throw away” out. This effect, added to the general expansion of the universe, would cause nearby galaxies to move away from us faster than normal. “This would give the appearance of a faster local expansion rate,” explains Indranil Banik, of the New Research. The Hubble tension problem would thus become a local phenomenon, without the need to revolutionize the entire cosmological model. The sound of the Big Bang as proof. What the new study of Banik and Kalaitzidis contributes is a much more fundamental test based on barionic acoustic oscillations. Although we call them “the sound of the Big Bang”, they are not sound waves that we can hear. They are the traces that left the pressure waves that spread through the superdense plasma of the primitive universe. These waves were “frozen” about 380,000 years after the Big Bang and created A characteristic pattern in the distribution of matter. This pattern works as a cosmic rule of about 500 million light years in length, which astronomers use to measure the expansion of the universe to different eras. The results. The team analyzed 20 years of measurements and compared them with two scenarios: on the one hand, the homogeneous standard model, without emptiness; and on the other, the model that includes the empty KBC. The results, presented at the National Astronomy Meeting 2025 of the Astronomical Society Royal, are blunt. According to the statistical analysis of the study, the model with a local vacuum conforms to the data in a spectacularly better way. While the standard model has a 3.3sigma voltage with observations, vacuum models reduce it to only 1.1sigma –1.4sigma. Calmly. The researchers consider “demonstrated” that A vacuum model is about 100 million times more likely than a model without emptiness. However, it is a preliminary study, which has not yet gone through the pairs review. Previous studies set very strict limits to the existence of such an influential vacuum, concluding that it is not enough to explain the entire Hubble tension. They also propose early dark energy as a solution. But Banik’s work offers one of the strongest evidence to date that the Earth could be in a very lonely region of the universe.

The last public employment offer leaves a revealing fact after years of record figures: Spain needs more officials

by

In recent years, the Pedro Sánchez government has promoted public employment calls that have broken historical figures for the number of public employment places. However, the new Public Employment Offer (OPE) for 2025 that has just known a turning point marks. Although it will have 36,588 new places, this figure represents a reduction with respect to the previous calls, and shows a worrying reality: the lack of personnel in the administration. New call 2025. The New Public Employment Offer presented by the Executive contemplates a total of 36,588 places, which represents a decrease of 9% with respect to the 2024 offer that was 40,146 places. Specifically, the number of places corresponding to the General State Administration is reduced mainly, which this year adds 26,889 positions, that is, 4,500 less than the previous year. This marks a change of trend against the years in which the calls carried the label of “historical” for its volume of places. The Independent Trade Union and Officials (CSIF) summarize it Clearly: “The places are insufficient to cover the losses accumulated in the administration of the State in recent years”, in addition to the majority union of the officials, they slide that the absence of new budgets and the freezing of funds of the European Union are already noticed in this call. Distribution by bodies and lack of personnel. Among the bodies that will be reinforced their workforce are the State Security Forces and Bodies. According to official data, the National Police Corps will have 3,139 new places, 300 more than the previous year, while the Civil Guard will add 555, reaching a total of 3,713 new places. The army too It will increase its template In 2025, with the incorporation of 2,847 new troops, 200 more than in the previous year. For its part, the Central Administration will have 20,324 new free access places, which will add 6,565 internal promotion places, which must be covered with part of the new 20,324. In that quota, 8,851 places of new allocation are also included to strengthen citizen service services in the offices of the SEPE, foreigners, cadastre, issuance of the DNI, DGT, Social Security or Tax Agency. The challenge of the generational relief. Since the current government arrived at La Moncloa, he says have summoned 260,000 public employment places. As Minister Óscar López highlighted in the presentation of the OPE by 2025, this leaves an average of 32,522 annual public places. Even with that effort, the reality is that the structural needs of employment in the public sector continue to be effective. As reflected in the EPA data (Active Population Survey) of the first quarter of 2025, for the first time since 2018, public employment registers a decrease of 51,900 people in its template. Thus, although the calls try to compensate for accumulated casualties, the balance is still negative. One of the main challenges facing the administration is to absorb the Retirements planned for the next decade. According to collected data In the study on the aging of the templates in the General State Administration 2024, 59.95% of the staff of the General State Administration is over 55 years old. This aging forces the administration to Compensate retirement that each year occur, with new additions. In 2023, for example, the number of retirement was 10,758 officials, while only 8,770 new officials were incorporated to cover those places, leaving a deficit of 1,988 positions that were not covered that year. Below the average public employment in the OECD. Internationally, the data does not accompany. According to the report ‘Government at A Glance 2025’ Of the OECD, Spanish public employment represented in 2023 15.25% of the total active population, below the average of 18.41% of the OECD countries. In addition, despite the increase in the number of places, the Public Employment Growth It has been developed at the same rate as private employment, without equating the boom that other countries have applied to balance essential public services.

The first prohibitions to diesel cars over 10 years are already underway. There is only a small detail: there are no

by

Gasoline cars that comply with Euro 3 and diesel cars that comply with Euro 4 or Euro 5. That is the definition made by the DGT of the vehicles that They carry the bchatin B in cars. Although, really, what traffic has done has been discriminating for years of enrollment. Thus, cars with stickers B are enrolled between 2000 and 2006 for gasoline cars and Between 2006 and 2014 for diesel. This decision has generated some inconveniences since there are vehicles enrolled before 2000 (gasoline) or 2006 (diesel) that comply with the aforementioned emission regulations. But, except those exceptions that can be reviewedcars with stickers B are at least ten years behind them if we talk about diesel vehicles. Discrimination has raised some controversies since the owners of these cars face more hard restrictions than gasoline cars. To sticker equality, his car is many less years old. And that opens the door to be prohibited to diesel cars more modern than gasoline in our cities. Restrictions that, as you have been able to read, are already applied or will arrive very soon. But they do not exist. An exception (very exceptional) In recent days, social networks have been filled with messages that point to alleged prohibitions to cars with sticatin B. that is, gasoline with more than 19 years behind them but diesel with just over 10 years. But the truth is that when one goes to detail, those prohibitions They do not exist or, at most, they will be very soft restrictions that do not limit the use of the car. First, you have to understand that Since 2023 All cities with more than 50,000 inhabitants had to launch low emissions (ZBE) areas to improve air quality. But in the regulations It was not established how they should be These, who had to affect nor a punishment was established for not doing so. This has caused many municipalities to choose not to apply the measure, claiming that they needed clear orders from the government (aware that it is a measure that can negatively affect the electoral level). But it has also caused Paradoxes like Ciudad Realwhere you aspire to establish a ZBE … where all cars can access (even those who have no environmental labeling of the DGT). If we use the map that the government itself has active and select Restrictions by B labelwe will see that only the city of Segovia, Madrid and Barcelona remain active. In Madridcars with b label can circulate without problem but in the area of low emissions of special protection center center (ZBEDEP CENTER DISTRICT)they are obliged to park in a parking lot, whether public or private. It is the same restriction as when the area was called Madrid and there are no firm plans to change it. The case of Barcelona is a bit more special. Right now, all cars with stickers can circulate within the Metropolitan Area of Barcelona (AMB) without restrictions. Of course, cars with stickers B are included. The point is that The Generalitat of Catalonia has given green light to a plan to put obstacles to its use. That plan puts on the table restrictions on cars with B label from January 1, 2026 in all cities of More than 50,000 inhabitants within Catalonia as long as the anti -antamination scenarios are activated. That is, when the pollution is so high that it forces to prohibit circulation to some vehicles. It is something that It is also contemplated in Madrid In some scenarios. The protocol does contemplate the restriction of cars with B label B but as of January 1, 2028. By then, those cars will be over 14 years in the case of diesel and more than 22 years if we talk about gasoline. In Catalonia, cities with more than 50,000 inhabitants are Barcelona (and all the municipalities that already enter the AMB), Lleida, Tarragona or Girona, among others. You can consult here on this link. However, in the plan it is only specified that they will have to have a ZBE and that it must restrict the circulation to the cars with environmental label B but the size of it is not specified. That, just as it happens in the rest of the territory, has proliferated cities where Zbe barely affects a handful of streets, without substantial impact for the vast majority of drivers. That is what happens in Salamanca, the only city that Restrictions to cars with sticatin B already applies throughout Spain. However, the size is just 0.37 km2, the historical bud. Inside can access the aforementioned vehicles if they are registered in that area or if they do it outside the schedule established for the application of the ZBE: Monday to Thursday: from 7 a.m. to 8 p.m. Fridays, Saturdays and Vespers of festive: from 7 to 23 hours. Sundays and holidays: 10 to 20 hours. Much Runrún and few prohibitions In spite of everything, in some media we continue to read that there are already prohibitions raised to cars with almost immediate application B label, as inferred in the holders. Then we leave a list of the most commented cities and what will be applied or not. Bilbao: This zbe It has a size of 2 km2 and is active from Monday to Friday from 7:00 a.m. to 8:00 p.m. In that time section, from June 15, 2025 cars with B label B of the DGT are forced to enter a parking lot (as in Madrid) but can enter with that condition until January 1, 2030. By then, these diesel cars will have at least 16 years. Estepona: This zbe It has a size of 0.49 km2 and is also located in the historic center. Here, cars with stickers B are obliged to park in a parking lot or in a hotel, as in the previous case of Bilbao. There are no more restrictions. Getafe: This zbe It has a size of 1.18 km2. Since 2025 it has the same … Read more

I’ve been sleeping badly for years, so I’ve tried “sleep headphones.” They haven’t been what I expected

by

I’ve been sleeping for years regulate. The classic culprits are discarded: I don’t take late or copiously, I don’t drink alcohol, I don’t take caffeine, I do sports, No mobile abuse just before going to bed… Simply I find it hard to fall asleep and sometimes wake up at several times during the night. So I wanted to whose car more and more manufacturers are climbed. In my case I have tried the Anker Soundcore Sleep A20. Let’s see how. What they are and what they promise Sleep A20 are wireless headphones designed exclusively for sleep. The first thing for what they attract attention: they are dwarves. The second: They are very light. The third: its profile is very low, they do not stand out from the ear. The closed box. Image: Xataka. Image: Xataka. Image: Xataka. They also come with several silicone and “wings” tips to adjust it, something especially important in some vermin that we are going to take sleeping for hours. The important thing is that they are not just headphones: Its application includes several environmental sounds, sleep monitoring and specific functions for the night. They can work in two modes: Bluetooth mode to reproduce any sound from our mobile. Sleep mode with soured sounds in the headphones. The experiment The first night was adaptation. I had never slept with a headset in my life. In addition, I usually sleep sideways. It seemed unlikely that a headset did not bother me. Minipunto for these, because I immediately forgot that I was wearing them. The flat design and the soft, gummy, flexible material, made it barely noticed additional pressure. Zero problem. They stand out practically anything. Image: Xataka. Image: Xataka. Then there was the issue of listening. Put to try, I let the application surprise me with its own proposals, which they call “brain waves with the” created specifically to help us fall asleep. We can choose whether listening to them only for a while, only until we stay asleep or all night. I tried the three: Only for a while: It gives what it promises. If we mark 45 minutes, at 45 minutes it will stop ringing. Only until we stay asleep: The same, detecting the moment we fall. All night: What a bad time. The sound made me wake up a couple of times, something disoriented by him. Perhaps it is a personal issue and there are people who have a reparative dream with the headphones sounding throughout the night. It is not my case and I advise to set the timer in a generous way to ensure that the shutdown will occur. The Yay and the Nay There are four elements that work really well here: Exceptional comfort. They have never been a nuisance. They are soft and with the low profile they are not noticed or sleeping sideways, as a soil alternate. Spectacular battery. 14 hours in sleep mode is something that I can never check for myself. After seven hours of night use, when they woke up they still had about the remaining 50%. Passive noise block. Without active cancellation, but with the right tips they isolate surprisingly well. Reasonable, at least. Useful sleep monitoring. The application records sleep phases, number of turns in bed and preferred position. There is enough correlation with what it says My garmin on duration and phases. And then there are four other elements where they fail. Mediocre audio. That nobody expects audiophile quality. Nor is it the vocation of these headphones. The sound is functional, music lacks depth and warmth. Very limited pre -recorded sounds. There is some variety, but many sound compressed and artificial. The most effective are the noise of color (white, brown, pink). Application Faluta. He tells me that I slept 16 hours when the reality is that at seven hours I took them off and left them on the bedside table. I should understand that absolute immobility for nine hours cannot be equivalent to very deep sleep. In addition, it is not very intuitive when applying one way or another. Problematic tactile controls. In the dark it is easy to activate some function. About the application Falutathere is an example. I have not sleeping 11 hours possibly from the day before my birth. That lack of logic in detection is a negative point. Yes, you can see how much I move during the night: my wife says that 16 turns seems like a fairly reasonable figure. The data collected by the application. Image: Mockuuups Studio, Xataka. Also Atina that I am only able to sleep aside, and I have quantified what I already imagined: I usually sleep more towards the side of the edge. The final verdict The big question with these headphones is whether they really help sleep better. The answer, in my experience, is not. I did not notice differences between the nights with them sounding before sleeping and the nights without them. I thought That the scientific approach of pre -registered sounds would better induce sleep, but it has not been so. My Garmin data, with me every night, indicate very similar patterns with them and without them. And something worse when I tried to wear them playing all night, as I said before. At 150 euros are not cheap, but Yes I see them a clear target audience: the people who need to fall asleep listening to something. For that, I don’t think there are much better options for the low profile and night comfort. And without disturbing the bed couple, if there is. There I see an obvious sense. But for those who do not sleep wonderfully and look for allies of any kind to fall asleep, and not to simply hurry a podcast of True Crime Until we fall round, at least in my experience, these headphones do not miracles.

We have found tools 300,000 years ago in China. And they put up legs what we believed on the paleodieta

by

Imagining humans diet of tens of thousands of years is to think, almost automatically, in the Paleodieta. For years we think that ‘paleo diet’ consisted of Eat, above all, meatbut more and more studies have put on the table that our ancestors They were not as carnivorous as we thought. And, from time to time, tools appear that support that Vegetable diet in antiquity. The last? Chinese tools with at least 300,000 years old. The discovery. In an article published in Scienceresearchers detail a series of 35 wood tools found at the Gantangqing archaeological site, located in southwest China. Using methods such as Electronic spin resonance On sediment minerals attached to tools, researchers have been able to date with a 95% confidence this set of tools in a segment between 250,000 and 361,000 years. This collection includes Tools of all kindsas large sticks to dig two hands, hooks and some smaller supplies, and researchers detail that they all have clear manufacturing marks such as rounded ends, more sharp parts and other polished surfaces. Collectors. The hunt was present at the time and was of great importance, obviously, but we have already commented that there is more and more evidence about the relevance of the collection and the Vegetable diet before the agriculture. The estimate is that these tools did not serve for hunting, but to process plant foods. The analysis of both the waste that presents the tools and the use brands indicate that they were designed to excavate and collect grounds and tubers and roots. Hook -shaped tools, for example, could have served to cut the smallest roots and tools to clean vegetables in a precise way. Contrast. Almost as interesting as the tools themselves is precisely that collecting purpose. The reason is that in Western Eurasia and in Africa they had already been found Wooden tools Of that age, but the enormous difference is that most tools were hunting while the Gantangqing repertoire, apart from more diverse, specializes in that plant collection. Importance beyond diet. Although they are tools of the last years of the Paleolithic inferior in which rock tools were more than established, but there was the hypothesis that, in East Asia the rocks were less abundant than in other regions and populations depended largely on organic tools. And that need forced the elaboration of the tools made from wood. And, above all, the discovery puts on the table that cognitive abilities of the population of Southeast Asia and its ability to create advanced tools was comparable to that of European and African contemporaries. In the end, it is always curious to verify how a “simple” discovery, as a tool of tens of thousands of years ago, allows to establish a connection with the diet of that population, their skills compared to those of other areas and how they raffled difficulties to continue advancing. And also how the stone that We always associate the Paleolithic He was not the only protagonist in the technological evolution of the species.

The Neanderthals invented it 125,000 years ago with their “fat factory”

by

Although demonized for a long time, fat is one of the essential macronutrients for the correct functioning of our body. More recent studies and habits are putting the fats in their place placing some like Allied in healthy dietsbut thousands of years ago, who already knew the role of fat in the body were the Neanderthals. To the point that just discover A giant “Factory” of fat in Germany. Short. Neumark-nord It is an archaeological site that is southwest of Berlin and a few kilometers from Leipzig. It is a place not alien to researchers, since a study in the area a few years ago revealed How the Neanderthals already did what we are doing so well: deeply modify the landscape in which they live. Without leaving the customs of those Neanderthals who inhabited the area 125,000 years ago, we have new details about their customs. Posted in the magazine Science Advancesa new study shows how Our ancestors They had an “industry” around the processing of the bones of large mammals with a single objective: extract bone fat to consume it little by little. Fat factories. A study of more than 2,000 bone fragments and dozens of flint tools It has allowed researchers to observe in many of them signs of having used to crush, have been crushed and have an exposure to intense heat. In some specific areas there was a concentration of bones rich in marrow, as well as anvils and folk that would have been the Tools used by Neanderthals. This concentration reinforces the idea that the site was used as a kind of “factory” to extract fat in a rather laborious way. According to the researchers, to get that bone fat, they broke the bones of 172 mammals such as deer, horses or cattle. Once they reached the marrow, the small fragments in water crushed and warmed it to extract the fat. It was a planned, long and, the researchers affirm in Livescienceorganized to maximize the extraction of nutrients from animal remains. Bones damaged by a hammer Fighting “rabbit starvation”. Why complicate life so much to get fat? The reason is simple and we must return to the diet. Follow one balanced diet To be healthy it means that we must eat a certain amount of fats, proteins and carbohydrates. When one of the tables of the table decomposes, health problems appear. That they put so much effort to get fat in this way may mean that there were times (perhaps the coldest) in which Carbohydrates scarce and could not feed exclusively with proteins. A decompensation thus (which we now do with Diets like Keto) It is dangerous, above all, if it is accompanied by an intense rhythm of life in which energy is needed. Consuming too much protein without sufficient fat can cause something called “starring rabbit”, A potentially deadly condition that is caused by excessive consumption of lean meat without enough fat. And it is not that the rabbit is the animal that suffers it. It was baptized like this because Arctic Explorers They fed almost exclusively with similar rabbits and animals and fell seriously ill because our body cannot metabolize large amounts of proteins without sufficient fat. They only improved when they could hunt animals with more fat. Ahead of the clock. Our body may burn carbohydrates or fat to obtain energy, since Protein is not a good “fuel”and if the carbos were scarce, the Neanderthals turned to fat. Where from? Of what they had closer: the bones of the animals that had hunted to feed. That they realized this implies that perhaps we should stop seeing them as those little sophisticated “hunters” that we can imagine sometimes. It also indicates that They were organized and quite ingenious. And, more important than this consideration, that large fat factory in Germany advances the resource intensification industry clock in almost 100,000 years. Before this analysis, the oldest evidence of a similar industry Databa 28,000 years ago. Images | Athree23 In Xataka | The Neanderthals left a deep genetic footprint in us.
