Awakening in the middle of the night is common

by

It can be something occasional or something recurring, but it is something that happens to almost everyone (especially as our age progresses), waking up in the middle of the night. Sometimes it occurs for no apparent reason, although this “apparent reason” can be a night visit to the bathroom. Waking up in the middle of the night can be usual, but why does it happen? The question is important although it also hides another that many people will have done. It is the one, regardless of the annoyance, it is this loss of sleepworthy sleep. Sleep interruptions can cause insomnia problems, but can also respond to other stimuli of different kinds. In a recent interview in The avant -gardeSleep Psychologist Roser Gort pointed out some of the factors that can contribute to these inconvenience. First of all, GORT indicated that sleep interruptions are usually completed a pair of sleep cycles, an important factor since these cycles are linked both with the depth of our dream and with the very function of this. During each sleep cycle our brain passes through four phases: a REM phase (rapid eye movements); and three phases NO-REM, each deeper than the previous one. The REM phase is the phase in which dreams occur and in which it is easier to interrupt the dream. During a typical night we cross several cycles but the relative duration of each phase in them changes, as well as the very duration of the cycle: the first cycles will see longer deep phases, while in the final cycles the REM phase will gain prominence. If we generally wake up a couple of cycles, it is logical that we always wake up at the same time. But let’s go back to the key matter: what are the factors that make us woke up easily. Stress is one of them. According to Gort indicatesthe cortisol (the colloquially called “stress hormone”) tends to accumulate in our body from a certain time of the morning (between two and four) when our stress levels are high. The early appearance of This hormone It can facilitate we woke up at such hours in the morning. “Stress can also harm the quality of your dream,” they explain from Sleep Foundation. “Sleep and stress are probably affected by each other, with poor dream impacting your ability to manage stress and stress by impacting your ability to sleep well.” From the Foundation they also point out how The hormones They can also play an important role in these contexts. Hormones play a key role in the functioning of circadian rhythms, the “internal clock” that indicates when to sleep and when to remain awake. Hormonal changes, Add the FoundationThey can take you to wake up in the middle of the night. This also implies that events that influence our endocrine system, such as pregnancy, can affect our sleep and vigil cycles. One of the factors that can affect the continuity of our dream is age. As we become older, our body requires less sleep. This not only affects the total of hours that we sleep at night, it can also increase the probability that we wake up in the middle of the night without apparent reason. Some sleep problemssuch as insomnia or sleep apnea can also be behind our problems to keep us asleep. Finally, there are external factors that can also influence our ability to sleep “from the pull”. Factors such as our daily habits or medications that we can be consuming can also make our dream more fragile. Recovering the dream Waking up in the middle of the night can be a problem for those who have difficulty falling asleep. Awakening in the middle of the night can mean to lose a valuable sleep time, so some experts have been interested in this find ways to reconcile sleep quickly and effectively. Often We can wake up With the prevailing need to urinate. The problem is that this visit to the bathroom can contribute to reveal us making us more difficult than we reconcile the dream. According to Gort explainedit is not so much our bladder that awakens us on such occasions but that when we wake up we realize that we have to release its content. If we want to avoid this we can reduce our fluid intake in the hours before we go to bed. Avoiding this night walk can help us, but experts suggest A series of tricks To help us recover sleep. The first: not to look at the clock to check the time it is, since this probably generates anxiety and makes our dream difficult. There are almost as many ways of sleeping as people. Our dream depends on many factors, such as biological, work or social.

The strange buzzing that you can only listen to at an age. The frequency that Japan, the US and Europe uses against young people

by

In 2009 IHe listened to listen for the first time in the streets of Tokyo. For years, the Kitikahama Parkin the district of Adachi, he had been recurring white of acts of vandalism, especially in public facilities such as bathrooms and urban furniture. Damage, mainly attributed to groups of adolescents who frequent the area at night, had meant a significant cost for local authorities. And since then, a Imperceptible noise For much of the population has been recurring. A sound that has its origin in Europe. The mosquito. Years before, in 2005, the New York Times spoke of the arrival of an invention to the United Kingdom. What began as a child auditory discomfort was transformed years later into an unusual solution for a persistent urban problem. Howard Stapletona British engineer, he remembered how, at age 12, upon entering a factory with his father, he was forced to go out immediately by an unbearable sound that adults did not even perceive. Decades later, that experience led him to create The mosquitoa device that emits a high frequency buzz perceptible only by young ears (mainly around twenty) and practically inaudible for those who have passed thirty. Its purpose was as direct as controversial: drill teenagers that congregate in noisy in front of stores, generating discomfort, intimidations and even episodes of theft and violence, without the need for direct confrontation. Personal idea to experiment. The first real mosquito test took place in Barry in 2005, a town in southern Wales, in front of a spar grocery storemanaged by Robert Gough and his family. Before the installation, the place suffered daily La presence of adolescents They smoked, drank, insulted customers and broke into the establishment. Gough had considered resorting to classical music to large volume, but never implemented it. It was Stapleton who offered to install the device testing. In a matter of little time, the usual congregation of adolescents disappeared. Some tried to resist, entering the store with their fingers in their ears and asking to turn off the buzz. Gough, ingenious, told them that the device was to scare birds due to avian flu. The result was a Radical transformation: Before conflicting teenagers now entered, bought, and they went without causing problems. Mosquito installation in a Philadelphia store It hurts, but it doesn’t exhaust. We talk about a device that emits a kind of chirp pulsating by Above 17 kilohertzup to 75/80 decibels, comparable to a noise of tinnitusIt is not painful, but very irritating. Stapleton said he tested different frequencies with the help of his own children to formula That “I did not harm, but it would bother enough to want to leave.” His intention was never punishing, but Simply dissuadecausing an discomfort that pushes the adolescent to retire on its own. While some adults can still perceive the sound, the device is designed thinking about behavior patterns rather than strict age ranges: hardly a 30 -year -old person is around the entrance of a store for hours. Professor Andrew King, an expert in neurophysiology at Oxford University, I recognized years ago To the Times that although the hearing of high frequencies decreases with age, that loss is gradual and, therefore, some adults could also hear it. Stapleton will consider it irrelevant: “The mosquito is not for them.” Cross borders. After its appearance, the mosquito It generated great interest. Stores, railway deposits, shopping centers and British local authorities They requested units. Stapleton, at that time, already contemplated more powerful versions Activable by panic button, designed to repel crowds that enter into mass to steal, which in the United Kingdom is known as Steaming. Its logic It was simple: “It is difficult to steal with the fingers in the ears.” From Europe and the US to Japan. Four years after the invention was established in different cities from the United Kingdom, then Europe, and finally the United Statesthe mosquito made the leap to Japan. Given the numerous acts of vandalism, the district of Adachi decided to resort to the controversial technological solution, but growing in popularity. Pilot test In Japan, some shops and They had implemented Previously after receiving complaints about garbage, noise and concentration of youth groups, but 2009 was the first time it was installed in A public park. The Adachi administration, which had hired the device to the Melc Co LTD company, based in Chiyoda, installed it in the area as part of an essay that would last until March 2010. Background: Vandalism costs in the 470 parks and public areas of Adachi in the previous years had overcome the 3 million yenso any solution that could reduce non -invasive figures represented an attractive option. According to Melc representatives, the objective It was clear: generate an environment uncomfortable for offenders without altering the tranquility of the rest of citizens or provoking neighborhood complaints. And in the trains. Although today the number of facilities of this type is unknown in Japan, in the social networks They abound videos and comments of young people alluding To this type of sounds. Bloomberg had that even a version of the mosquito has also been installed in trains stations. In many of them ultrasonic devices had been placed that emitted a high frequency sound only noticeable for children under 25 years. The devices, designed to discourage merodeus without confrontations, caused obvious reactions In students: discomfort faces, accelerated steps and complaints, without most knew where the sound comes from. Meanwhile, older adults walk imperturbable, unable to hear the signal. The technology, originally from Wales, had found in Japan its most systematic and culturally accepted use. Between defense and stigma. Counted in a long NPR interview to Stapleton that the mosquito has generated a debate about the Technological intervention limits in public space. While some celebrate their ability to restore tranquility in commercial and school areas without violence or clashes, others consider that their indiscriminate use It can be equivalent to criminalizing the default youth. Stapleton responded That the true enemy is not adolescence, … Read more

We have found the first narcosubmarino with Starlink. It is a new step in drug logistics

by

The drug trafficking industry It has an important challenge that does not go through producing the drug, but to distribute it. Of conventional networks infiltrating the product in commercial vehicles or using ‘mules‘, the drug traffickers have controlled huge fleets of submarines. These craft vehicles baptized as ‘Narcosubmarino’ have experienced a boom In recent years, and the striking thing is that they are updating in terms of technology. So much that a narcosubmarino without a crew that is controlled at a distance, thanks to StarlinkElon Musk’s satellite Internet network. And, obviously, it is a new headache for Maritime authorities. Short. It was a few days ago when Colombia’s Navy reported On a strange finding that made the first week of April: a narcosubmarino ‘stuck’ to a boat that had the capacity to transport ton and average drug. Neither by size nor by capacity was a ship that caught attention, since in recent years the capacity of this type of boats has increased to transport more drugs. What was striking was the antenna in the front. In that area He was A Starlink antenna, Elon Musk’s Internet service for which every time More satellites are displayed To increase global coverage, and we can imagine the usefulness of such a system in the operations that a narcosubmarino can perform. Advanced remote control. No crew was found, so it is speculated that this connection with Starlink would allow new generation drug traffickers operate semi -autonomous. That is, someone on land would perform the functions of remote controller, assuming a huge advantage if the authorities intercept the ship because they would be carried out with the cargo, yes, but not with human operators. Now, apart from logistics advantage and facilities when navigating any type of water thanks to that global satellite connection, the authorities estimate that this technology represents a major challenge for anti -drug forces because it will make them more difficult to track. Narcosubmarine are not real submarines in many cases, but semi -submersible that can escape the ‘vision’ of radars, and without humans inside, they can also go more unnoticed to tracking systems. In addition to the Starlink system, the ship has two cameras, an internal to monitor both the transmission and the engine and an external one for the vision of the trajectory and that the operator can avoid obstacles. Of all sizes. Having caught a narcosubmarino for remote control thanks to Starlink supposes One more step in the drug trafficking network and demonstrates how their vehicles are adapting thanks to the latest technology in order to be more efficient. Because the one seized by the Colombian Navy was empty and estimate that it was a proof unit, but that there is already something like that, surely, it implies that there is more on their way. Because if something is clear, they are investing in the construction of these ships. It is estimated that, in 2009 there were about eight vehicles of this style, a figure that reached the 180 estimated in 2020. Obviously, there are many gray in all this because they are estimates. World Network. Many of those narcosubmarinos are usually precarious ships with a short useful life, but also There are more sophisticated And in recent years we have seen semi -submersible Greater and sophisticatedsome reaching 30 meters long with designs very, very similar to the submarines used by world armies. In fact, a few months ago Colombia’s Navy intercepted A ship that had the Australian or Neozelands coasts as an objective, implying that there is no country that escapes Colombian drug trafficking networks, consolidated as the heart of cocaine world imposing increase in production These last years. As much as it may be, and although it has only been a test, that a narcosubmarino has already caught with Starlink assumes that the drug traffickers are already ‘Armando’ with vehicles capable of operating remotely, even in areas to which the traditional coverage does not reach, with all that it implies. And compared to the first vehicles in the early 90s, It is a huge step and a great challenge for the authorities.

For centuries the Christians pilgrimage to a remote cave to venerate Salome. Problem: They were wrong with Salome

by

There was a time, many centuries ago, in which Christians went to an old cave located in the Judea Lowlandsnear the village of Eliav, in search of inspiration. Over the years even a Sacred place For Islam. There (the remains of Salome were supposed to be, a biblical figure with echoes in the origins of Christianity. Some versions identified it as the midwife that attended the birth of Jesus. Others as one of his disciples and witness of the crucifixion. It is even said that she was Maria’s little sister. Now a group of Israeli archaeologists has reached a fascinating conclusion that relies on vestiges located years ago In the cave: I probably Salome that rested in his day in the crypt was neither the midwife nor disciple of Jesus, but an opulent and powerful aristocrat related to Herod. In a place of Judea … The Salomé cave is a wide sepulcher located in Sefeláthe lowlands of Judea, with an exceptional archaeological value. In fact there are those who consider it one of the funeral caves “More impressive” discovered in Israel and “More elaborate” of his time, the known as period of the Second templewhich extended between the centuries VI AC and I DC Specifically, experts believe that the crypt built between the I AC and I DC The cave itself is no novelty. The archaeologists excavated it decades ago, in the mid -80s, after they were located. Throughout the last years, however, they have expanded our knowledge about the grave. By 2022 A group of experts from Israel Antiquies Authority (IAA) made an excavation in part of the enclosure that revealed new data on its architecture and history. He also confirmed that for several centuries that remote Cave of Sefelá was used as a veneration space. And how is it? Wide. Elaborate. And fascinating. The archaeological set includes a lobby, a large patio surrounded by silry stone walls and a funeral cave with several cameras in which they were preserved Kokhimfuneral niches excavated in the rock, in addition to ossuaries. Although archaeologists studied the thorough crypt in the 80s, a few years ago they wanted to go further, analyzing in depth The 350 m2 courtyard and cleaning the inside of the cave. “The patio turned out to be one of the most elaborate of its kind compared to other cemeteries of the same period,” he says An article Posted by the IAA. Among other things, experts met stones with Jewish motifs and “delicate plant designs,” such as rosettes, grenades and acanthus vases. Nothing to do with most access courtyards to funeral caves found by archaeologists, who are usually excavated, not raised with masonry. Cave … and pilgrimage place. If the grave is so relevant, it is not only because of its size, architectural characteristics or decoration. There is another equal or even more relevant factor. For a while the cave was a pilgrimage place. During their excavations of 2022 and 2023 in the front courtyard, archaeologists discovered a row of positions in which clay lamps were sold and rented. “We find hundreds, complete and broken, dating from the eighth centuries and IX DC”, They explain Nir Shimshon-Paran and Zvi-Fire, directors of the excavation. “The lamps may have served to illuminate the cave or as part of religious ceremonies, similar to the candles that are distributed today in the tombs and churches,” They add. In the cave, Greek, Syriac and Arab inscriptions, recorded crosses and indications that reveal that the funeral space remained in use during the Byzantine and Islamic periods were also located. “The excavations show that, in the Byzantine period, the site had become a place of Christian pilgrimage,” experts say, which tells us about a wide period of worship that covers from the 5th century to the IX DC DC The cave of Salome. The question was obvious … Who belonged to the funeral cave? Who rested in his day in the crypt? And why the archaeologists found crosses and dozens of inscriptions recorded directly on the rocks of the walls? The answer is both simple and complex: the Sefelá cave was the resting place of ‘Salomé’. Among the inscriptions in different languages, archaeologists identified several in Greek that mention that same name, ‘Salomé’, supposedly a religious figure relevant to Christians. In An article Published this year on the sepulcher, IAA experts remember that, in the 1090s, the scholars that analyzed the inscriptions have already concluded that the first monks who arrived in the cave in the Byzantine period discovered an ossary with the inscription ‘Salomé’, a relatively frequent name in the Judea of the beginning of the beginning of Christianity. “During the second temple period it was not common Explain Paran to The Times of Israel. “It is possible that the cave contained an ossuary with the name of Salome, although we did not find it. It could have been looted.” So … who was the famous Salome? The midwife of Jesus? A tradition attributes that name to a figure that appears in it Protoevangelio de Santiagoapocryphal text in which a Salomé is cited as a midwife that doubted the virginity of Mary. The story tells that his disbelief earned him a punishment that ended up turning it into a symbol. “According to the Christian tradition, Salome was the midwife of Bethlehem who was called to attend the birth of Jesus. He could not believe that they asked him to participate in the birth of a virgin and his hand dried. He only healed when he held the baby’s crib,” Remember From the IAA. Other versions They place Salome as a disciple of Jesus, Mary’s sister or has even confused her with the mother of Santiago and Juan. “The cult of Salomé, sanctified by Christianity, belongs to a broader phenomenon: the Christian pilgrims of the 5th century found and sanctified Jewish places. The name Salome could have appeared in ancient times in one of the alter’s already disappeared from the tomb and thus the tradition … Read more

Spain is the favorite caramel of hackers

Spain already has the third most attacked domain in the world, the .es. It only has a .com and .ru, a fact accompanied by reports that suggest that cybersecurity incidents 64% have increased in the country Regarding the previous year. A situation that It does not improve despite the response of Europe And that raises an immediate question: what does Spain have to be so sweet? And one more. Cofensecompany specialized in defense against phishing, has detected a increase of up to 19 times more attacks on domains. in the period between the last quarter of 2024 and the first of 2025. 99% of these attacks focused on phishing. The other 1% went to distribute different remote access Trojans. The method. The growing attacks on addresses. They use one of the simplest methods to infect a computer: email. Simulating Microsoft addresses. From these C2 servers (Command & Control) the attackers can send personalized commands to the computer. In other words: Capture the screen Register what you write Activate or deactivate the camera and microphone of the PC Access PC files Why Spain. Spain is one of the whites more attractive in the world for cybercriminals. Experts like Francisco Valencia, director of Hackrisk.io, points to several reasons for this to happen. Strong international presence of Spanish companies. Geographic position as a bridge between Europe and America (submarine cables such as Marea, Grace Hopper) Changes in the global context after Brexit and deviation of attention to countries such as the United Kingdom. They are not the only suspects. The rapid digitalization of companies after the arrival of European funds The attack radius increasedweaknesses in small and medium enterprises, and a public administration exposed to vulnerabilitiesand geopolitical interest in the country make Spain The second objective with more cyber thrames detected globally. The impact. Some of the cyber attacks received in recent weeks are making the Spanish administration itself, preventing access to the systems of some municipalities in the country, and having affected authorities such as CNMCeither national companies like Repsol and Telefónica. Recent cases. While I write these lines, Spain is mired in two cyber attacks that have left KO the systems of two municipalities. The first is that of Melillawhich adds two weeks under an attack whose authorship a Russian group has been awarded, and the second one that of a small Alicante municipality that has suffered the same fate: Villajoyosa. The answer. In May 2025, the Council of Ministers approved a package of 1,157 million euros To reinforce national cybersecurity, a budget distributed between defense, digital transformation and public function, interior and the Department of National Security. The focus is being put also in processing the transposition of the NIS2 directives and the EU Regulation Dora. In other words, force the critical sectors of the country (energy, telecommunications, health, finance …) to notify cybersecurity incidents and implement more robust risk management systems. At the moment, none of the efforts seems to be materializing in real improvements. In Xataka | How to change all our passwords according to three cybersecurity experts

a selection of getaways full of fun and strong emotions

by

Nothing more summery and familiar than visiting an amusement park. In Spain the offer is considerable and covers all kinds of options: the most traditional with roller mountains and free falls, others with more informative approaches and shows, set in different historical times. Passing, of course, through the inevitable aquatic parks, the most refreshing sites to spend summer. We have made a selection of the best attraction parks in our country, so that you do not escape a change of ground in the wagon this summer. Portaventura World (Tarragona) Nothing less than 52 hectares distributed in six thematic areas inspired by civilizations such as China, Mexico or Far West. More than forty attractions for all audiences, some as legendary as Shambhala or Dragon Khan, and a couple of extras, the Caribbean aquatic Aquatic Park, and Ferrari Land, with the fastest attraction in Europe. In addition, they are celebrating for the 30th anniversary of the Park, which guarantees a year of special activities and celebration. Warner Park (Madrid) A thematic experience based on the world of cinema and the characters of Warner Bros, and that is distributed in five areas: Hollywood Boulevard, Movie World Studios, DC Super Heroes World, Old West Territory and Cartoon Village. There are classic attractions such as Russian mountains or the highest free fall tower in Europe, but the authentic appeal is in the encounter with the characters of cinema and television, or the shocking show Batman – Gotham City Escape. There is also aquatic park, ideal for summer months. Attraction Park (Madrid) The classy amusement park, located in the Casa de Campo, offers an experience for the whole family distributed in five thematic areas: Great Avenue, Tranquility, Machinism, Nature and Nickelodeon Land, the latter with children’s attractions and franchise characters for the little ones, such as SpongeBob and the Canine Patrol. The park has more than thirty attractions ranging from the classic Russian mountains to others of aquatic type. There are also live shows, special events such as the Magic Festival and, of course, the classic and inevitable Caserón del Terror. Magic Island (Seville) A DIDACTIC THEMATIC PARK Historical atmosphere: the discovery of America. It offers six thematic zones and attractions that, as always, cover all kinds of styles: roller mountains such as jaguar and aquatic highlights. Its magical water area has artificial beach, wave pool, slides and slow river, which makes a perfect option for summer. As always, there are live shows, also with an educational touch, like many park activities. Mythical terra (Benidorm) Terra mythical also opts for the historical setting, this time around the ancient Mediterranean civilizations with five thematic zones: Rome, Greece, Egypt, Iberia and the Islands. Among its most adrenaline attractions are a 54 -meter free drop that reaches 100 km/h, the flight of the phoenix, and a brutal roller mountain of extreme speeds, titanid. The mythological theme of all attractions (Achilles’ anger, Triton’s fury …) give a unique touch to the park, of the most recognizable in Spain. Unfortunately, its coponstruction also has An intrahistory in which there is space for the embezzlement of the real estate bubble. Tibidabo (Barcelona) Another attraction park, such as Madrid, which has a great tradition, located on the top of the mountain of the same name, which makes it the owner of a privileged natural environment, with great views of the city and the sea. It has more than 25 attractions for all ages, with classics such as Avió, Talaia and Carousel, and also roller mountains and more modern free falls. There are aquatic attractions, educational spaces, live shows, also the historical and essential Museu d’A autòmats and access to the funicular. An amusement park, no doubt, different. Dinópolis (Teruel) Another openly educational and thematic approach park, this time focused on the always fascinating world of dinosaurs. It has interactive and mechanical attractions, such as Torresaurio, and shows such as the T-Rex Show, where the one that is announced as one of the most sophisticated animatronics in the world makes an appearance. It also has, of course, a paleontological museum with fossil skeletons, and all kinds of simulators to discover how dinosaurs lived. Siam Park (Tenerife) It is considered one of the best aquatic parks in the world, and also has a curious special theme, little seen here: everything has Thai style and decoration. Like any amusement park, it has brutal and adrenaline attractions, such as the Singha aquatic roller coaster or the free of free of power free fall (28 meters high, 80 km/h, crossing an aquarium of sharks and mantaryas), and others calmer, with swimming pools and a water racing. There is artificial beach, a slow river and shows with marine animals. Katmandu Park (Magaluf) An absolutely familiar orientation park, with ten attractions where fun without shocks and technology takes prominence. For example, in the star and more original attraction of the park, The House, a house upside down where reality ceases to make sense. There are abundant aquatic and soft areas for children, a thematic minigolf, a small attraction of laser shots in the west distant and an adventure of zombies. A good alternative if you are looking for accessible fun for all ages. Aquopolis (Villanueva de la Cañada, Costa Daurada, Torrevieja, Cartaya and Cullera) A network of aquatic parks in five parks distributed in Spain: Villanueva de la Cañada (Madrid), Costa Daurada (Tarragona), Torrevieja (Alicante), Cartaya (Huelva) and Cullera (Valencia). Each park has all the expected attractions (high -speed slides and vertiginous falls to safe children’s areas and wave fishing). According to the park, there are even hospitality areas with cabins and VIP areas away from the crowds. Puy du Fou Spain (Toledo) The most recent of all the thematic parks in Spain, which adds to historical settings, here with a fantasy and color bath to recreate through theatrical representations historical episodes of the history of Spain since the 5th century. It has a spectacular night show, ‘Toledo’s dream’, which summarizes 1,500 years of history in 70 minutes. Apart … Read more

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.

The US has taught the tariff rope with Brazil again. Embraer has a lot to lose, and its customers too

by

If you live in Europe, fly in a Embraer is not the most common. But the truth is that these Brazilian planes are more present than they seem. In airports such as London City, Where only a few models can operate, these jets dominate the track. Even in Spain his footprint was remarkable: Air Europa had several E195 in its regional fleet until the beginning of 2023. Embraer is not a minor actor. It is one of the world’s largest manufacturer in the world and its e-hes-especially the E175– They hold a good part of regional traffic in the US. Airlines such as American, Skywest and other regional United Express operators have clearly opted for them. With Boeing in low hoursEmbraer is emerging as an emerging candidate for the select group of the great manufacturers. A tariff triggers uncertainty President Donald Trump has threatened to apply A 50 % tariff To Brazilian products as of August 1, an unprecedented offensive in relations between the two countries. In parallel, Brazil already mentions a mirror answercovered by a recent reciprocity law. Although there is still no confirmation about which sectors they would be exempt. With a large part of Embraer’s orders aimed at the US market – where almost 95 % of firm orders from E175 come from airlines such as American, Skywest and other United Express operators -, the new measure threatens to significantly increase their products significantly. Not only will the final prices of the jets be affected, but the cost of the Imported components from the United Statesessential for manufacturing, it could also be affected if Brazil decides to apply, in retaliation, an equivalent rate. Among those components are enginesCF34 manufactured by General Electricthe airplane system Honeywell Primus Epicas well as landing trains and actuators supplied, mostly, by Collins Aerospace (USA) and Liebherr (Europe). An essential part of each aircraft that, if more expensive, would also impact the production costs of the aircraft destined for other markets. This dual effect could have broad spectrum consequences. On the one hand, airlines could be forced to Reconsider your purchase strategies If the price jump translates into higher operational costs. On the other, if the manufacturing cost is increased, Embraer’s global competitiveness would be compromised, even in regions where its position is solid. As Flightglobal collectsEmbraer has indicated that he is evaluating the impact of this measure on its operations and has been active in the dialogue with the authorities to try to restore the exemption of the import tax that has historically favored the Brazilian aeronautical industry. However, queen uncertainty. This tariff is part of a Trump communications series to leaders of more than twenty countries, with warnings that rates can modify “according to the relationship.” The lack of regulatory clarity leaves manufacturers such as Embraer – and suppliers, airlines and passengers— In a difficult situation to anticipate.

“The countries that do not manufacture their own drones will be vassal states”

by

Elon Musk has put his cards on the table with A lapidary phrase: “We better discover how to build drones quickly or we will be doomed to be a vassal state.” Only China manufactures scale drones. And a certain electric car company could supply that need. The harsh reality. “The United States cannot currently manufacture its own drones,” said Musk At a results conference of Tesla. At first glance, it seems a classic exaggeration of the entrepreneur. American military suppliers such as Aerovironment (manufacturer of the Switchblade-600) or General Atomics (creator of the MQ-9 Reaper) design and produce drones. However, Musk does not refer to the ability to design these unmanned ships, but to the scale production and independence of the supply chain. In this sense, China’s dependence is overwhelming. Not only by the United States. China controls between 70 and 80% of the world market for commercial drones, which They are actively used in the Ukraine War. And critical components such as batteries, chips, cameras and engines come mostly from China. “China manufactures more drones on a day than the United States in a whole year,” Musk said. A 9 billion market. But Musk’s warning is not just a patriotic outburst, it also has a business reading. According to a Morgan Stanley reportthe drone and Evtols sector could reach a value of 9 billion dollars from here to 2050. It is a cake too large for the South African businessman not wanting a piece. The movement would charge special relevance at the current time of Tesla. The company recorded a drop of 71% of its net benefits during the first quarter of 2025, with a 52% sales collapse in a single month. The incipient deployment of robotaxis does not seem enough to convince shareholders, and bet on such a large market could be the solution. The pieces fit perfectly. Tesla already develops advanced robotics with humanoid robot optimus and autonomous systems such as autonomous computer -based computer driving. Spacex, your sister company, closes the circle with an unmatched knowledge of the aerospace sector. Musk itself showed the movement in the call to investors, speaking about Tesla’s future: “The future of the company is based primarily on large -scale autonomous cars and on a vast number of autonomous humanoid robots.” Drones fit as a glove in this vision of “robots with affordable artificial intelligence.” The pentagon is knocking on the door. China’s geostrategic dependence has not gone unnoticed in Washington. The pentagon has launched the “Replicator” initiativea 1 billion program to deploy thousands of military drones, selecting the Switchblade-600 Aerovironment as its first public purchase. In parallel, the Department of Defense has promoted a reform to eliminate the bureaucracy and achieve the “domain of UAS” by 2027. The message is clear: the United States shares Musk’s concern and is trying to recover the lost terrain to forced marches. Musk’s statement about the “Vasallos states” is, say, a play for several bands. Image | Flickr (DVIDS) In Xataka | China conquered us with its cheap drones.

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.
