We have just confirmed, to no one’s surprise, that Neanderthal dentists were real butchers

Go to dentist or having maxillofacial surgeons for many people may be something that arose with our species and our great intellectsince we do not conceive that in prehistoric times our ancestors were worried about their teeth. But now we know that Neanderthals They had dentistsalthough logically with the techniques of the time. An evolution. Until now we knew that Neanderthals used small wooden sticks to get clean food scraps, something that, to be fair, some modern primates also do. However, a new find In the icy mountains of Siberia, what we thought we knew about prehistoric medicine has just been blown up. And it was not a simple instinct, since Neanderthals knew how to locate the source of acute pain and use stone tools to perform invasive dental interventions like those they can do to us today. Although logically we no longer have stone as a surgical material. Patient zero. The discovery that is the protagonist of this story has been named ‘Chagyrskaya 64’, and it is nothing more than a lower left second molar that belonged to an adult who inhabited the Chagyrskaya cave in the Altai massif in Russia. We even know that he belonged to a group that represented the most eastern known Neanderthal populations. Via: PLOS. Images of the tooth analyzed by the researchers. A tooth. At first glance, the tooth had a huge and unusual cavity in its upper part where it performs the chewing function. At first, archeology attributed this to the natural wear of the piece due to friction when chewing hard foods or simply from having received a blow. However, the edges of the cavity were smooth and rounded, so accidental breakage was completely ruled out. Furthermore, the pulp chamber, which is nothing more than the inner part of the tooth, was widened in a way that wear could not explain. What was happening. The answer to everything centers on the fact that the tooth had a severe cavity that someone tried to cure by force, removing the entire area of ​​the tooth that was in the ‘worst’ condition. And surely the pain that is felt with a cavity of considerable size that reaches the nerve area of ​​the tooth was the trigger for having to do this technique. Rustic dentistry. To prove that this hole was made on purpose, the research team used micro-computed tomography and extensive traceological analysis to see traces of use. Here what was seen is that the walls of the cavity had V-shaped stepped microgrooves, identical to those left by a perforator lithic, which was a sharp stone tool. And to confirm this, experts conducted experimental archaeology, replicating the drilling and rotation process on ‘modern’ human molars. And the brands matched perfectly. A conclusion. With all this information we can know that there was an individual who not only survived the brutal intervention in life, but also continued chewing with that tooth, as demonstrated by the subsequent polishing. It is true that they had no option to ‘cover’ that hole in the tooth as dentists do now after removing the cavity, but it did not prevent him from continuing with his normal life. A cognitive leap. Beyond the medical anecdote, the reality is that solving a cavity by excavating the infected tissue requires quite complex rational reasoning. Although we see it as easy now, identifying the source of the pain, conceiving the idea that it can be eliminated, selecting the tool for that task and executing precise rotary movements with the fingers is not easy. That is why this ability separates this behavior from mere animal instinct and shows that Neanderthals were more advanced than many of us had in mind.

A superyacht has just crossed Hormuz before the astonished gaze of the US and Iran. Its flag has confirmed that mines are not for everyone

In 2019, during one of the highest recent tensions in the Persian Gulf, several marine insurers they raised their premiums so much that some shipowners chose to keep their ships anchored for weeks rather than crossing certain routes considered too dangerous. In parallel, other ships continued sailing with relative normality thanks to apparently minor details such as their registration or the documentation they carried, making it clear that, even in times of greatest uncertainty, not all ships play with the same rules. A strategic step converted into a global funnel. we have been counting. The Strait of Hormuz, through which about a fifth of the world’s oil normally circulates, has become one of the most tense points of the planet after the outbreak of the conflict between the United States, Israel and Iran, with traffic plummeting from more than 130 ships daily to just a few dozen and hundreds of ships trapped waiting for safe conditions. The situation has skyrocketed energy prices and generated a domino effect in global trade, while Tehran demands permits to cross and Washington threatens to intercept certain movements. In this scenario, crossing this bottleneck has become an operation fraught with military, legal and economic risks. Or maybe not so much. A superyacht that defies the blockade. Because in the midst of that collapse, he Northa luxury superyacht valued at just over $500 million and linked to the Russian oligarch Alexei Mordashovachieved what very few have achieved in recent weeks: crossing Hormuz from Dubai to Oman without incident. With more than 140 meters in length, several decks, a swimming pool, heliports and even a convertible hangar, its journey not only contrasts with the general paralysis of maritime traffic, but also makes it a striking anomaly in an environment where even large oil companies prefer not to take risks. Your journey, monitored in real timefollowed routes that other ships have used with some type of coordination in the area, although without official confirmation about permits. Alexey Mordashov The invisible key. Possibly the most revealing element of this episode is not in the luxury of the ship, but in how did he get through without being detained or attacked, in a context where any ship can become a target. Everything indicates that he achieved it with a combination of factors: not heading to Iranian ports (which would place it outside the direct focus of the US blockade), sailing through corridors tolerated by Iran and, above all, operating under a diffuse legal structure where the formal property does not entirely coincide with the real one. In other words, in an environment where each movement is interpreted as a political signal, the flag, the chosen route and the legal ambiguity act as a kind of tacit safe conduct that allows one to move between red lines without completely crossing them. Geopolitics, sanctions and alliances in the background. Of course, the journey of North cannot be understood without the political background that surrounds it, marked by the close relationship between Russia and Iran and by the fact that Vladimir Putin maintains a strategic support to Tehran in full escalation with the West. Mordashov, one of the men richest in Russia and sanctioned for the United States and the European Union since the invasion of Ukraine, you have already seen other seized assetswhich has led many oligarchs to move their assets to safer jurisdictions. In this context, the passage of the yacht through Hormuz also becomes a sign of the extent to which certain networks of power and alliances can influence what, in theory, should be a total blockade. A symptom of how conflicts work. Beyond the anecdote, the episode reflects a dynamic increasingly common in contemporary conflicts: while great powers impose restrictions and threats, they always there are gray spaces where specific actors manage to move thanks to combinations of diplomacy, crossed interests and legal loopholes. The fact that a luxury superyacht can cross one of the most dangerous points on the planet in the middle of a crisis, while hundreds of ships remain immobilized and frightened by mines and drones in the surrounding area, illustrates how power is not only measured in military capacity, but also in ability to browse (literally and figuratively) between rules that are not always applied uniformly.

an Arabic document from the 17th century has confirmed its existence

If we think about characters and civilizations in African history, most of us think of the pharaohs and pyramids of Ancient Egypt and little else. However, there is much more and you don’t have to go far from that enormous continent: just to the south, following the river inland, there were powerful kingdoms with their own kings, their own cities and their own cathedrals (yes, I said cathedral). One of those kingdoms was called Makuria, and its capital was Old Dongola, a great city on the banks of the Nile that for almost a thousand years was a center of power, commerce and culture. Curiously, while Europe was living through the Middle Ages, Dongola was a prosperous Christian city that even stood up to the Arab armies that conquered North Africa. Over time it declined, became Islamized and was almost forgotten, buried under the desert. The history of the region Nubia It is almost a documentary silence. It’s not that nothing happened: it’s that almost nothing was written or what was left had not been excavated. In that darkness, a small fragment of Arabic paper recovered in a garbage dump in ancient Dongola (the north of present-day Sudan) has just marked a before and after. The discovery. The document measures just 10 × 9 centimeters, it was found in a garbage dump inside Building A.1 of the Old Dongola citadel (what has been popularly known there for centuries as the “King’s House”) and it is an administrative order issued in the name of King Qashqash. The king orders a subordinate named Khiḍr to arrange an exchange of sheep with their offspring, cotton cloth, and a headdress between several individuals. The text was written by the scribe Hamad and the research team behind the paper considers that it is probably the response to a previous letter, suggesting that there was an active epistolary network around the court. It is, simply, the king working on his task of administering, managing assets and relationships within his network of power. The first face of the King’s order. M. Rekłajtis/PCMA in Barański et al. 2026 Why is it important. The relevance of the discovery has several levels, but the most direct and immediate is to confirm the historical existence of Qashqash, of which there was previously only evidence through oral tradition, including fragments of the Kitāb al-Ṭabaqāt of Wad Ḍayfallāh. This book compiled in 1700 compiles the biographies of the most important saints and religious teachers of the Sudan, based on stories that had been transmitted orally from generation to generation. Beyond that confirmation, the discovery sheds some light on what the “Dark Ages” of Nubia were like. For centuries the image left by Leo Africanus in the 16th century predominated, describing the king of Nubia as a monarch perpetually at war. This document demonstrates the opposite: the region was politically active and its king was not on the battlefield, but rather involved in the daily management of goods and networks of reciprocal exchange, which was the central mechanism of political power in precolonial Sudan. Context. Old Dongola was the capital for centuries of the Christian kingdom of Makuriaone of the most powerful medieval African kingdoms in the Nile Valley. In the mid-14th century it ceased to be so, and the city progressively contracted until it was reduced to its citadel and its immediate surroundings. What followed is the period that historians call the Sudanese “Dark Ages”: three centuries in which Dongola was caught at a geopolitical crossroads: with pressure from the north by Ottoman Egypt, from the south by the Funj sultanate, and meanwhile its society was Islamized. It was in that delicate context that Qashqash probably reigned between the second half of the 16th century and the first years of the 17th century. one of the first rulers of that dark period that has been able to be verified. How have they done it. The PCMA research team at the University of Warsaw have combined three independent avenues to date and contextualize the document: with numismatics using Ottoman silver coins from the same stratum, radiocarbon of organic matter from the garbage dump, and cross-literary genealogy, combining the Kitāb al-Ṭabaqāt and the account of the traveler Evliya Çelebi, the documented descendants of Qashqash. The convergence of the roads has made it possible to reconstruct the limits of when his reign was. Qashqash is just the tip of the iceberg. The document is also a linguistic testimony of the first order: written in Arabic, it has grammatical irregularities and colloquial spellings that show that although it was not fully established, it was already the language used by the chancellery. In short: evidence of the gradual Arabization of Nubia, which was adopted and adapted. Another interesting point is that archaeological evidence and local oral memory confirm each other. Building A.1 has been called the “King’s House” by the inhabitants of Dongola for centuries and the descendants of Qashqash continue to live nearby. Finding the royal order precisely there is no coincidence: it is archeology validating what the community had remembered for generations. In fact, the collaboration between the research team and those who live there has been close, something they consider essential for a correct interpretation. Shedding light on the dark ages. The Qashqash order is only the first published result of a much larger corpus as the project has recovered approximately fifty Arabic paper documents in Old Dongola, including letters, legal and administrative texts, and written amulets. The first analysis points to communication networks that connected religious, administrative elites and possibly nomadic leaders of the region. A comprehensive and in-depth analysis of the set will shed some light on the political, legal and social history of pre-colonial Nubia.

has confirmed that this war is going to haunt us for a long time

Every day they circulate around the planet more than 100 million of barrels of oil and enormous volumes of gas that depend on a few strategic points to reach their destination. It only takes one of those nodes to fail for the markets to react in chain in a matter of hours and the impact is noticeable from large industries to the final price of energy in homes. The red line that no longer exists. Because he latest attack on Iran He has not been just another member of the war: he has crossed a border that until now everyone avoided, that of directly striking energy productionnot just its transportation or its peripheral facilities. The sequence is clear and extremely dangerous, because first the gas fields are attacked, then immediate retaliation comes. against equivalent infrastructures in neighboring countries, and in a matter of hours the conflict can enter a logic of “eye for an eye” that has no turning back. In fact, what for years was the worst possible scenario for analysts and strategists (an open war against the energy heart of the Gulf) is no longer a hypothesis for become realityand that changes the very nature of the conflict. War against the system, not against objectives. attack the South Pars gas field It’s not just hitting one more facility, it’s hitting a central piece of the global energy system and Iran’s own internal workings, and the Iranian response. on Ras Laffan confirms that the message has been understood throughout the region. It is no longer about destroying military capabilities or putting political pressure, but rather directly damage the pillars that support states: we are talking about income, social stability and supply capacity. When a facility that concentrates near a fifth of natural gas liquefied planet can be engulfed in flames, the war stops being regional and becomes become systemicbecause its effects spread far beyond the battlefield. A war with the face of Iraq. Plus: the dynamic that has been activated is dangerously reminiscent of the gulf war 1991, when burning oil fields became a symbol of total war against energy infrastructure. If the current escalation continues, it is not difficult to imagine the next step: refineries, petrochemical plants and entire fields become priority targets, with prolonged fires and damage that can take years to repair. The difference is that now global interdependence is much olderwhich amplifies the impact and can turn each attack into a direct hit to the global economy. In other words, the war is no longer fought only with missiles and drones, but with the destruction of the capacity to produce and sustain the energy that moves the planet. An expanding goal board. The Iranian response It also hints at a deeper strategic change: one where, if its energy base is hit, any equivalent infrastructure in the region becomes legitimate objectiveincluding facilities in Saudi Arabia, the Emirates or Qatar itself in the equation. If you like, beyond the energy, the implicit message is even more disturbing: if this taboo is broken, other, perhaps more dangerous ones can also be broken. Because Iran still has the capacity to climb in other directionsfrom attacks on political and symbolic centers to more direct blows against power structures. In other words, if they touch the economic heart, they can begin to point to the political heart, and that opens up a range of scenarios that are much more difficult to contain. The war after the combat. From that perspective, the real problem is not only what is happening now, but what this implies for medium and long term. Destroying energy infrastructure is not something that can be repaired in weeks, and each impact can leave scars that most likely they will last for yearsaltering trade flows, regional relations and power balances. Therefore, possibly this moment be so decisive in the war conflict: because it confirms that we have entered in a phase of the same whose consequences will persist long after the bombings stop. It’s not just another war in the Middle East, it never really has been, but now it’s the beginning of a dynamic that can redefine how conflicts are fought in a region where, from now on, the limits are no longer clear. And that is what makes it more dangerous than any other.

There will be no insurance or registration for electric scooters on January 2, 2026. The DGT has confirmed it

On January 2, 2026, I aspired to put some order with electric scooters. At least, the order understood as the DGT understands it. And on that date, all electric scooters They had to begin to comply with a series of conditions. They would have been sold as new or were electric scooters that are already in the hands of users. Now, the DGT has confirmed that this will not be possible. In order to apply the new regulations, it is necessary to a Royal Decree that has not been approved and that, as of December 23, 2025, it will be impossible for it to arrive in time for the new year. Despite this, Traffic reminds us that it is mandatory to have insurance for it, which will have to be active before the end of January of next year. So… what has been approved and what is mandatory? No insurance at the moment From 2024all electric scooters sold in Spain have a certificate that includes the technical characteristics of the electric scooter. This certification serves agents to verify whether or not said personal mobility vehicle complies with the technical characteristics for which it was created. And it must be taken into account that an agent can stop an electric scooter but they are also being done controls in some cities. In bliss plate Data such as the maximum speed at which it can circulate must therefore be reflected. In addition, the DGT had to have a VMP registry ready so that anyone who had a vehicle of this type could register their electric scooter. This forces those who have a vehicle of this type before 2024 to have to send the electric scooter to one of the laboratories accredited by the DGT. It will certify that the vehicle is not modified and confirm that it meets the permitted technical conditions. This registration will be a kind of registration for electric scooters and every new scooter sold in our country must be registered. The intention was to leave this possibility to the private customer until 2027, but they were going to be forced to have civil liability insurance as of January 2, 2026. This left them on the verge of having to “homologize” the electric scooter no matter what. However, the DGT has today published a clarifying note in which it states the following: “The Council of Ministers, taking into account the urgency of the processing of the aforementioned Royal Decree, agreed on November 18, 2025, to process it urgently. Although the hearing and public information procedures have already been completed, its approval will not be possible before next January 2” Without this Royal Decree approved, the DGT confirms that there is no legal basis to be able to demand from users registration and insurance of the electric scooter. They assure that “the technical development for the registration of VMPs is already completed” but that without the regulations that regulate this approved, they will not be able to demand these two requirements from January 2, 2026. Therefore, electric scooter users will not have to have insurance for their electric scooters as of January 2, 2026. But, in addition, Traffic does not indicate from what date they expect this change to be active. They only specify that it is mandatory to have insurance as of January 26, 2026 for those personal mobility vehicles with a weight greater than 25 kg and a speed greater than 14 km/h. Electric scooters are considered light personal mobility vehicles and, therefore, insurance will not be required. At least for the moment.

The most detailed gravitational waves in history have just confirmed the great prediction of Stephen Hawking

After ten years Perfecting the detection of gravitational wavesLigo sensors achieved such a precise observation which has allowed physicists to confirm one of Stephen Hawking’s most famous predictions: the black holes area theorem. Ten years. A decade has passed since the scientists of the Ligo Observatory The universe listened for the first time in a completely new way: by detecting gravitational waves. On September 14, 2015, wrinkles in spacetime tissue Predicts by Albert Einstein a century earlier inaugurated a new era in astronomy. What was then an almost imperceptible cosmic whisper, today has become a symphony that sensors can clearly hear. And on the tenth anniversary of that milestone, the Ligo-Virgo-Kagra (LVK) collaboration has captured the most clear gravitational wave signal to date. GW250114. Detected on January 14, 2025, physicists believe that these gravitational waves were caused by the collision and subsequent fusion of two black holes to about 1.3 billion light years from the earth. Interestingly, the event is almost a twin that ended using Ligo’s physicists the 2017 Nobel PrizeGW150914. In both cases, it was two black holes with masses between 30 and 40 times that of our sun. But there is an abysmal difference: the signal quality. An unprecedented sharpness. Thanks to a decade of technological improvements and advances in quantum engineering, Ligo detectors are now almost four times more sensitive. While the first signal had a signal/noise ratio of 26, that of GW250114 has a 80. “We can hear it high and clear, and that allows us Physical Review Letters. This sharpness has been key to unraveling the secrets that were hidden in the vibrations of the black hole resulting from the merger. Hawking theorem. In 1971, Stephen Hawking proposed that the total area of ​​the event horizon of a black hole can never be reduced. It can increase or remain the same, but never shrink. This, which is known as the Hawking area theorem, is analogous to the second law of thermodynamics, which says that the entropy (the disorder) of an isolated system always increases. Therefore, the area of ​​a black hole is a measure of its entropy. Trying it is complicated. When two black holes merge, part of their mass becomes an enormous amount of energy in the form of gravitational waves (the famous E = mc²). In addition, the new black hole can turn much faster, and a larger turn implies a minor area for the same dough. Does the increase in mass compensate for these losses so that the final area is always greater? The analysis of GW250114 has been settled by the matter bluntly. Hawking was right. In this case, the two initial black holes had a combined area of ​​about 240,000 square kilometers. After the merger, the new black hole, with a mass of about 63 times that of the sun, it had an area of ​​400,000 square kilometers. If in 2021 a first test with the 2015 signal showed a 95%confidence, the new data raises that certainty to 99,999%. As Kip Thorne recalls, one of Ligo’s parents and Hawking personal friend, the British physicist called him right after the first detection in 2015 to ask if they could try his theorem. Hawking died in 2018but today his theory has been verified in a way that would have left him very satisfied. Einstein too. Thanks to this new signal, scientists have been able to analyze the moment just after the merger in which the new black hole vibrates like a newly hit bell before stabilizing. The frequencies and speed with which these tones are attenuated. It is the most solid test to the date that black holes are seemingly simple objects that can be completely described with only three properties: mass, spin and electric charge. All other information of the material that formed them is lost. But each detection of gravitational waves is one more piece in the puzzle of the cosmos. And as GW250114 demonstrates, to understand them we travel on the shoulders of giants such as Einstein and Hawking.

We sensed that Japan was very serious. The first shot at the JS Asuka with its electromagnetic cannon has confirmed it

In July Japan advertisement Something that surprised the world: he had physically mounted his riel cannon on the JS Asuka ship. In other words, the nation was already navigating with a science fiction weapon that the United States developed in the past, but had abandoned. A clear message that they were going very seriously. A message that has now taken full form. The Japanese milestone. Japan has achieved historical advance when performing the First documented test of a naval electromagnetic cannon fired at a real ship, installing a prototype in the Experimental ship JS Asuka. The Acquisition, Technology and Logistics Agency (ATLA) He has just confirmed That between June and July 2025 this essay was carried out successfully, which marks a before and after in the global race for new generation weapons. As we said at the beginning, this achievement takes on greater relevance because the United States Navy, than He led the field between 2005 and 2022, He left the project Due to its technical difficulties, while Japan He has persevered in search of a capacity that could redefine the naval war in Asia-Pacific. Technology, remains and possibilities. The so -called Railgun, capable of launching projectiles at hypersonic speeds Up to Mach 6.5 With charges of five megajulaios, it offers decisive advantages: Broad ammunition than missile in front of hypersonic missiles. However, it continues to face great technical challenges: Huge electrical consumption, complex cooling systems, the need to reconfigure the internal spaces of the ships and the extreme wear of the cannons after tens of shooting, which compromises precision and safety. The use of Asuka as a test platform reflects the need for open space on deck, something difficult to replicate in operating ships without expensive modifications. From prototype to operational weapon. Japan has invested in this field since mid -decade of 2010shooting in land facilities and designing naval and land versions mounted on trucks. The Ministry of Defense has already shown more compact turret models, designed to integrate into futures 13DDX destroyers or even in the modern ships of the Mayan class. ATLA seeks to improve The useful life of cannons, reduce energy consumption and achieve a viable shooting cadence, objectives that will determine if Railgun goes from being an experimental prototype to a real weapon in the fleet. A weapon for the era of hypersonic threats. In a strategic scenario where China develops long -range missiles and Russia experiences with hypersonic projectilesJapan contemplates the Railgun in response to the saturation of aerial defenses. His speed of shooting, his low projectile cost and his ability to attack VeloS targets make him A possible alternative To interceptor missiles, whose replacement in the sea is almost impossible. This context explains Tokyo’s insistence on maintaining the project despite technical obstacles. Competition and cooperation. Plus: Japan is not alone in this effort. China has been experimenting with Railgunswith the appearance of a prototype on an EPL Navy ship In 2018although its current state is uncertain. Türkiye too He has shown advanceswhile the United States, despite closing its program, is Taking advantage of technology of ammunition developed for land applications. In parallel, Japan has sealed Agreements with France To collaborate in the development of this technology and maintain contacts with the US Navy, opening the door to future cooperation. Strategic reading If the Japanese Railgun exceeds its engineering injuries, it will emerge as the first operational case that converts a technological promise fleetrebalancing the cost-interceptor equation against saturations and rapid threats. The United States could be reached with less friction thanks to its inheritance and a possible cooperation with Tokyo. China would do the same if you see a clear advantage in area denial, and it is possible that Türkiye would capitalize on land and point defense applications. In terms of tendency, everything points to a coexistence: missiles for the long value, railguns for fire volume and shooting cost, and energy weapons directed for terminal/short range, each covering its niche in a multicapa defense architecture. Continuity of military ingenuity. In short, Railgun symbolizes both the attractiveness and difficulties of military innovation. As at other times in history, when gunpowder or guided missiles promised to transform war, the question is not only if technology works, but if can adapt to logistics, costs and strategy of each country. One thing is clear: Japan, with Your demonstration On board Asuka, it is placed at the forefront of a race that is not over, and that could define how naval wars are fought in the second half of the 21st century.

He installed Windows 95 in a PS2 and confirmed why it is one of Sony’s most indomitable consoles

Someone set out to take a PS2 to the limit: to operate a desk operating system In the legendary Sony console. He got it, although not precisely in the way many could imagine. And he didn’t stop there. He also tried to operate a game as mythical as ‘Doom’. The idea sounds simple: take an ancient operating system and make it work on a console two decades ago. However, chow our 3D games colleagues collectjust look a little more closely to understand why that combination, in reality, is almost impossible. The experiment that led an operating system to a console limit The PlayStation 2 was market in 2000 with a custom -designed architecture for video games. Its processor, the Emotion Engineruns about 300 MHz and works with a set of instructions different from that used by the personal computers of the time. Next to him, Windows 95 —Caszado in 1995 – was created to function in X86 processorsas the Intel 386 or 486 classics. Since the PlayStation 2 could not directly execute Windows 95, a good idea was to simulate a compatible computer within the console itself. And that is exactly what he did The YouTube channel Metrabyte. Did not turn to a native installer – because it does not exist – but to the standard installation of Windows 95 within Bochsan X86 architecture emulator. To put it, the youtuber loaded a version of Bochs adapted for the console, connected a USB keyboardand started the process. At first he used a USB memory to advance with the installation of Windows 95. But he soon found an obvious bottleneck: the USB port of the PS2 barely reaches 1.5 MB/s. To avoid this, he ended up choosing a more handmade solution: moving the files to an old IDE hard drive – rescued from an IMAC and mounted on an external housing – that connected to the console. Windows 95 was not designed to execute from an environment emulated on a console, much less from such limited storage units. Each step required a lot of time. The process lasted a good part of the night. The author himself calculates that around 10 amalthough he admits not knowing exactly how long it took. But the system finally started. Windows 95 was on the screen. With your colors, your desk, your starting bar. He even managed to open Paint. The keyboard worked, although USB mouse was not recognized. The fluidity was minimal. And when he tried to execute ‘Doom’, one of his original ideas, the system simply could not with him.

Health has just confirmed that the new tobacco law goes after the terraces. And it is not the only environment that wants smokeless

Terrazas, Marquesinas, University Campus, Teaching Centers, Sports Facilities and Labor Vehicles will be some of the new environments where smoking will be prohibited. At least that’s what the Ministry of Health seeks, that is working to reform the current anti -tabaco legislation, with the objective of “protecting public health and” denormalizing tobacco consumption in shared spaces. ”The plan is part of a broader strategy that seeks to reduce the impact of smoking, a threat that, according to Minister Mónica García, causes 30 % of cancers. A commitment that had been paused for years. The measure is not new, but so far it had not left the drawer. In 2021 a draft had already been written With proposals in this line, also including an increase in tobacco taxes and a stricter regulation of vapeo. That plan, prepared with the recommendations of scientific and medical societies, was two years paralyzed until Minister Mónica García, who took possession in November 2023he boost him again. Click to see the message of the Minister of Health in X Social consensus has changed. The idea of ​​prohibiting smoking on terraces was one of the most controversial when it began to consider, but public acceptance data has evolved over time. A survey of The Spanish Society of Family and Community Medicine (SEMFYC) pointed out in 2022 that 72 % of the population would agree to expand these smokeless spaces, including part of the smoking citizenship. Although without mentioning a specific survey, Health has pointed out that the measures raised “are backed by a majority of citizens.” New devices, same regulation. One of the most relevant changes posed by the reform is Normative comparison of electronic cigarettes and tobacco devices heated with conventional tobacco. In practice, that implies that these products will have the same restrictions of use in public spaces, without exceptions. The text that develops this aspect already It has been sent To the European Union for its evaluation, within the usual procedure. The challenge: convert the draft into law. For now, the reform is in the elaboration phase and must overcome several filters. First, the approval in the Council of Ministers, and then a parliamentary process where the support of other political forces will be needed. Everything can change in that process. Even so, the ministry insists on the importance of progressing quickly. A national strategy for 2030. The fight against smoking is part of a more ambitious national strategy. The objective shared with the Spanish Association against Cancer is clear: achieve the first generation of young Spaniards free of tobacco by the year 2030. For this, in addition to expanding smokeless spaces, Health plans to promote the unique packaging, finance treatments to quit smoking from the National Health System and advance measures that hinder the access of young people to tobacco. Not only physical health: also mental health and equity. Exposure to tobacco smoke does not affect all people equally. The Ministry puts the Focus on vulnerable groupsas minors or pregnant people, and raises this reform from an equity approach. Every person, argues healing, has the right to safe environments no longer to be involuntarily exposed to smoke.
