We are going through one of the shortest days in history

by

If you feel that days fly, it is not just a perception of yours. Our planet is turning faster than normal. This July 22 is expected to complete its rotation 1.34 milliseconds before 24 hours, turning today the second shortest day of the year and one of the shortest since we have records. Earth accelerates. Until 2020, the shortest day registered had lasted 24 hours less 1.05 milliseconds. Since then, The shortest day of each year has overcome that threshold. In 2020 and 2021, the highest deviation was −1.47 ms; in 2022, of −1.59 ms; In 2023 he rose to −1.31 ms and in 2024 he came down again, marking the current record. The shortest day ever documented occurred on July 5 of last year. He lacked 1.66 ms to complete 24 hours. 2025 silver medal. The predictions for the summer of 2025 They pointed out three key dates in which Earth’s rotation could beat its speed record: on July 9, July 22 and August 5. Finally, the shortest day of 2025 was on July 10 with a deviation of -1.36 ms. According to the latest estimates, this July 22 will be the second most short day with a duration of 24 hours -1.34 ms. On August 5 it would be third with a -1.25 ms. The world upside down. The really fascinating thing about this phenomenon is that it goes against everything we know about the rotation of our planet. For billions of years, the land has been stopping for the friction of the tides generated by the moon. Our satellite steals rotational energy to the planet, causing the days increasingly long. In fact, it is believed that during much of the history of the earth, the days lasted about 19 hours. Why it happens. We don’t know. Some researchers They attribute it to the thaw of polar capsbut the redistribution of that mass of water to Ecuador could actually be moderating the acceleration, not driving it. Earth’s acceleration has no place in any of the oceanic and atmospheric models, so the scientific community suspects mainly from the depths of the planet. One possibility is that the liquid nucleus of the earth is slowing down its movement and, to preserve the angular momentum of the planet, this internal slowdown is being compensated With a slight acceleration of the mantle and the cortexwhich is what we experience on the surface. The second intercalar … negative. Earth’s acceleration has implications for time measurement. Since 1973, atomic watches mark the coordinated universal time (UTC). Occasionally, A “second interlar” has been added To resolve our watches with the terrestrial rotation, which Historically, he slowed down. Now, we face an unprecedented scenario: the need for a second negative intercala. If the acceleration trend continues, world timing could have to subtract a second of atomic watches Around 2029. It would be the first time in history that this type’s correction is made. Image | POT In Xataka | We know since time immemorial that the days last 24 hours. Except when the wind blows

Cruise employees with days of 11 hours a day and 7 days a week

by

In the brightest covers of the luxury cruises They pass Dream holidaysinfinite pools, spectacular buffes and night shows. But under all that fun, in the lower covers, the true human machinery that operates these is hidden colossi of tourism: A population of employees who work 12 hours. The cruise industry continues to grow: 34.64 million passengers will embark in 2025, according to The latest reports of the Cruise Lines International Association (CLIA), which has generated a record demand for personnel. Getting one of these jobs requires, in many cases, to master English, Obtain regulatory certifications and accept contracts for months, with minimal breaks and far from the home. Mass recruitment allows more and more workers in countries with emerging economies and low salaries to be part of the crew, such and As publishes I monde. Life and work on the lower covers. Under the luxuries of the main roofs, a diverse community of employees from India, the Philippines or Peru, Honduras or Colombia is crowded. There, the cabins cease to be private and the carpet is replaced by the cold metal. Most share a room with other companions, in two bunk beds and with hardly any places for personal rest, as confirmed The Alba Sud report ‘work on cruises. Of the extension to the intensification of the working days’. This 2021 report confirms that hierarchically lower positions support an average of 11.3 hours of daily work and 6.97 days per week, accumulating around 80 hours per week. Working conditions prevent having 24 -hour consecutive days and, when the cruise is on the high seas, the crew “does not enjoy any full day of rest. At most, a few hours of holidays,” says its authors. The law of the sea and precarious contracts. Most cruises navigate under convenience flags (such as Panama, Bahamas, Bermudas), with which not only many taxes dodge: they also allow to avoid strict labor regulations. Workers on board lack union representation and there is hardly any margin to negotiate rights or schedules. Social protection is limited to the essential: basic medical care and minimum rest, stipulated by the Convention on Maritime Work. The interpretation of these regulations is very lax and there is no benefit for maternity or guaranteed compensation in case of accident, nor is the right to strike of employees ensures. According to what was published by I mondewages vary according to the position, but the most common ranges for unqualified employees of cleaning, kitchen or maintenance range between $ 900 and $ 1,100 per month. Contracts usually extend between 4 and 9 months, after which employees return to their country for a period of two to three months until they summon them again for a new season. These periods are considered on vacation, but are not paid. Precarious, but save. Despite the hardness of conditions, work on a cruise It is still an aspiration For many employees from Southeast Asia and Latin America. “Working on a ship is a dream for me. So I think I will continue to do it while I can, because after 40, it is difficult to find work in the Philippines,” he said I mondeVanessa, a 45 -year -old Philippine who cleans cabins in one of those cruises. Working on a cruise maintains its appeal for those who seek to save for a specific goal, such as buying a house or setting up a business when you return home. “I can pay the education of my children,” added Glitz, lifeguard and single mother who has left her two children with her parents in the Philippines. Not having maintenance or accommodation expenses on board, they can send virtually all the full salary to their families and plan a more stable future than their country of origin allows. A job with a lot of rotation. According to the Alba Sud study, 81% of the employees surveyed received a Increase in workload After the stop of the pandemic, and 56% say that their day lengthening in recent years. Precarious salaries linked to the long days and the time they spend away from their families, make work on a cruise an activity with high labor rotation. Companies have recognized that it is difficult retain employees Throughout the season. “The challenge for companies is to hire people who are not going to stay in a port port. It often happens, so the company reassures when an employee has a family to send money,” he tells the French newspaper, Cédric Rivoire-Perrochat, co-founder of the Compagnie Française de Croisières Compagnie Naviera.

We have been dreaming of a temperature drop for days this week. Aemet believes that we still have the worst

by

The arrival of storms to the north third of the Peninsula has monopolized part of weather care During this week. However, for a good part of Spain, heat remains intense and in some areas this implies risks to the well -being of people who reside or work there. A red notice, by heat. The State Meteorology Agency (AEMET) has activated A red notice (Extreme risk) due to high temperatures in the east, south and west zone of Gran Canaria. It is one of the various notices that the agency will keep activated over the next few days as a result of high temperatures. According to the agency’s notices, the maximum is expected reach 40º In the Tirajana basin, a temperature that can be normal these days in some areas of the southern peninsular but has led experts to give the alarm. The notice also indicates the persistence of heat, with minimal temperatures above the 25º barrier, but which could reach 30º. That is, the “Equatorial nights”They will be the norm in this area. The eye put in the humidity. The good news is that the forecasts indicate a low relative humidity in the area. Wet heat It can increase The thermal sensation, but can also increase the risk derived from high temperatures by preventing our body from dissipating the heat it generates. The situation in the Canary Islands will also improve from tomorrow, although yellow warnings will still be activated due to high temperatures in the south of the island of Gran Canaria. Thermal relief, partly. The situation is partly extrapolated to the center and south of the Iberian Peninsula. Temperatures today They will be high in much of the country and Aemet has activated numerous notices by high high temperatures, among which the temperature notices of up to 42º in some areas of the interior of Andalusia. With the arrival of the trough, the storms will reach the peninsular but the thermal relief can be noticed in more extensive areas. It is expected that on Friday there are not only notices in the center and the west peninsular, and on Saturday the notices are expected to be limited to areas of the Mediterranean basin. Waiting. For now we do not know what will hold us next week. Medium -term forecasts They predict a second half of the month of July warmer and dry than normal in most of the territory, so a heat return would not be entirely strange. For now we will have to wait to approach the passage of the storms and at the end of this warm episode before knowing what will hold us the last weeks of the month.

Erect “11 days”, Onlyfans and police eviction

by

Juan Bernabé’s is a story worth fighting for the summer snake title, but of all 2025. Although his name may not tell you much, for almost a decade and a half this 57 -year -old Cadiz, Admirer confessed from Mussolini and Franco, he exercised as a welfare of The SS Lazio. His mission consisted basically to take care of, love and work with Olympiaan imposing eagle that embodied the emblem of the Italian team. That gave him fame and made him by extension into a celebrity (an almost symbol) of the club chaired by Claudio Lotito. So it was at least until January. Now Bernabé is out of Lazio, It has ended up evicted and a new career is looked like ‘Disseminator’ of Penian prostheses In Onlyfans. What we said: firm candidate for summer snake. Who is Juan Bernabé? The (ex) scerero of the SS Lazio. And against every forecast one of the undisputed protagonists of the Italian football chronicle, although for reasons that little (or nothing) have to do with sport in general. What has given him fame is his penis. Or rather, his efforts to show it. Before explaining it in detail, it is good to know some brushstrokes of the character. Gaditano, 57 yearsfornido, fond of motorcycles and a wax of profession, Juan Bernabé devoted himself for almost 15 years to take care and fly to his Águila Olympia about him Olympic state of Rome before each party. The bird ended up embodying the club’s symbol (known as Aquile and that incorporates one in Your shield) and with it he did it in some way the trainer himself. “After my family, the fans are the most important in my life,” Bernabé presumed in September 2010just after the bird first volume on the stadium. A relationship with curves. Recently, during An interview with The worldBernabé remembered that he arrived at Lazio almost almost in a stroke of luck. “After flying to the eagle at the stadium, the sound of ‘with you split a,’ a man so excited that I told him would do the same, for free, for his team, Lazio. He was the great journalist Andrea Pesciarelli“. That was the beginning of a professional arrow that ended the Cadiz living in Formllo, owned by the club. For a while the relationship between Bernabé and Lazio seemed to march relatively well. Two years ago the club broadcast A statement to publicly transmit your condolences for the death of your father and last year He did the same when he lost his brother or even celebrate his birthday. However, the passage of the Cadiz by Aquile He was also tarnished by the controversy. In 2021 Lazio already The exit door pointed to him After Bernabé caught doing the fascist greeting to the voice of “Duce, Duce!” At the end of a match, although later the club chose to back down and readmit it. The welfare has denied being fascist, although it does recognize being An admirer from Mussolini and Franco. And the great controversy arrived. The fascist greeting and his recognized “Admiration” for Franco and Mussolini’s legacies had a pass in the eyes of the Lazio directive. What did not have was what he did earlier this year: Show your penis. After passing through the operating room to insert him a Hydraulic prosthesisBernabé decided Show the results In networks. And he did it big, with photos and videos in which no details were saved. He was so proud of the result that he even talked about the issue in interviews, which aggravated the board of directors. Defenestrated in the act. To Claudio Lotito, president of Lazio, Senator and who presume If a Mass had not skipped in 67 years, the attitude of the welt (and the consequent mess in networks) bothered him so much that his pulse did not shake when he was fired. He has recognized himself. “When they warned me, it took me an hour to fire them both,” he presumed in An interview. “I preach values, command the eagle to generate enthusiasm among children and then this person has this behavior of moral decline. He has violated the ethical code of Al Lazio.” That ‘second’ fired of which Lotito speaks, by the way, was the team’s urologist, Gabriele Antoniniwho practiced the operation to Bernabé and posed in some photos after the operation. The statement Regarding the expulsion of the welt, of dry and very hard tone, it was published on January 13: “The club understands the shared pain that the loss of the eagle in the next games will cause fans, but believes that it is not possible for us, especially for the historical symbol of the eagle, being associated with a subject whose attitude has made the relationship inadmissible.” History is complicated. In case the waters did not go down enough, Bernabé did something that ended up rooting his relationship with Lazio: he continued installed at the Flamllo Sports Center alleging that he was convalescent of the penis surgery to which he had undergone. Pashed January, February, March, April, May, arrived June … and the patience of the club ended up consuming, which led him to broadcast A statement On the 28th in which he reported that, “fulfilling an order from the Tivoli court,” he had thrown Bernabé from his facilities. “The decision occurs after the termination of the contract months ago. The club, after numerous requests for voluntary eviction, has taken the appropriate measures to protect its assets and the operation of the sports environment,” Lazio alleges. Bernabé’s version is something different. In An interview with The world He ensures that eviction was executed days before stipulated and that when the Italian police knocked on his door to throw it, he had not yet recovered from the operation. “With erect penis for 11 days”. “Five policemen touched my door. I could barely move, but I opened. When the inspector looked at me I said: ‘If I want I get out of bed and … Read more

Melilla has been with a total collapse of its computer systems for three days. The cyber attack is there

by

Those responsible for the Autonomous City of Melilla indicated last Sunday night that the city’s computer services had been interrupted by technical causes. At the moment the origin of the problem is not known, but a cyber attack is investigated. Although that hypothesis is not confirmed, there is a reality: that Spain is the second most attacked country in the world by cybercriminals. What happened. On Sunday night the City Council of Melilla reported That “due to a technical problem in our computer systems, we inform citizens that, temporarily, it will not be possible to provide services through the OIAC (Information and Citizen Attention Offices).” The cyber attack hypothesis. As they point out In the Melilla lighthousethere is no official confirmation about the origin of the problem, but working on the hypothesis of a cyber attack. In that investigation, the Autonomous City has the support of the National Intelligence Center (CNI), with which maintains a collaboration agreement in cybersecurity. Collapse (almost) total. The fall of computer systems in Melilla has made the usual tasks of the administration cannot be carried out by computer. That has forced them to recover in certain cases Traditional processing methods as the manual firm to process the most urgent files. The Minister of Development, Miguel Marín, explained in statements to the media how “obviously this slows the work.” The municipal website, which allows citizens to be done through the Internet, is also falling. Three organizations are still operational. As they point out In News from Navarraonly three public bodies have been saved from the fall: the municipal housing and land company of Melilla (Emvismesa), the Promise and Immusa Economic Development Society, on which local television depends. There is no date for the recovery of systems. Both Marín and the president of the Autonomous City, Juan José Imbroda, pointed out that the priority is to recover the operation of the services. However, the initial objective of recovering them in two days has not been met, and there is no estimated date for computer systems to work normally again. Denunciation and investigation. Although there is no confirmed cause of the problem, there has been a formal complaint due to the possibility of a possible cyber attack. “The police are alerted,” said Imbroda, “we will try to find out what has really been and where it comes from.” Image | Trevor Huxham In Xataka | Carrefour received five identical cyber attacks and did nothing.

Vigo Airport has released a digital tower “at the forefront of efficiency.” Has lasted four days

by

Announced as “the avant -garde of efficiency and safety in the air sector”, Vigo airport has begun working with “the first digital tower of Spain.” Four days later, the work has stopped for a first problem. And, in the background, the doubts about its real effectiveness, the position of workers and the shadow of some layoffs. Vigo, now with Digital Tower. It was announced by Oscar Puente, Minister of Transportation, with the words we collected above. In a tweeton June 17, the politician pointed out that Vigo received a strong change in his way of working. The project started with a Vigo-Madrid flight and was qualified by bridge as “a technological milestone” that places the facilities of Vigo “at the forefront.” Four days later, the entire system has had to stop by a Error caused at 31 minutes to go into operation. What is a digital tower? A Digital Tower For air control, it comes to replace traditional control towers. In the latter, controllers work at great height to control by computer systems and their own view air traffic. In this way, it is always about choosing the best option to manage the entry and exit of flights into the maximum safety conditions. A digital tower uses all these computer systems but changes the “windows” of the screens control tower in which what the cameras see are recorded. In addition, it has a multitude of sensors and microphones to simulate with maximum precision the same sensations as an air controller has in a traditional tower. Is it better? According to the words of the Minister of Transportation, yes. AND According to Aenaalso. They ensure that the videoWall that forms 13 55 -inch monitors represent a 360º image of what is seen in the tower. This allows them to have visibility of areas that are covered in the traditional tower. The installation, as we say, has fixed cameras and two mobiles. As well as “speakers that reproduce the ambient sound of the microphones installed in the flight field.” In addition, AENA points out that “they provide a series of operational and security advantages” although it does not give examples of them. And emphasize, because it is important, “maintaining the same number of controllers.” War foot. That last part of the message is important. In social networks, numerous accounts that expose the feeling of aerial controllers have been radically opposed to the implementation of these “digital towers.” The well -known account @Controlerators in x He qualifies the digital tower of “basement with cameras designed to control several airports”. And that is the great reset that has raised among the workers. In the environment, the feeling that operations of the Airport of A Coruña can be replaced with the air management of the Viguesa Digital Tower. Alvedro (A Coruña) and Peinador (Vigo) share a company managing air control services (Saerco) so A reduction in the number of workers is feared For a remote control of both airports. In The voice of Galicia They even point out that AENA neither confirms or denies that A Coruña workers can be replaced by the new digital control tower. BNG and the Popular Party They are already working to paralyze the project. “Quite obvious defects”. In addition to the works that may be in the air, the Union of Air Controllers (USCA) ensures that Aena has rejected its request for include “high definition cameras” And they emphasize that the system does not improve the traditional because “They are not clearly appreciated Small aircraft. “They are, in the words of the” quite evident defects “union. They emphasize in words to Vigo lighthouse that the system presents operability restrictions in specific weather situations and that “would entail the imposition of time restrictions that would prevent the simultaneity of visual flights (VFR) and instrumental (IFR).” That is, for the union, a problem for “urgent health transport, customs surveillance, fire extinguishing services or maritime rescue, as well as schools or private flights.” Many doubts. Although Aena points out that “currently, more than 30 European airports have implanted that technology and is operating from a digital control tower. Outside Europe, initiatives are being developed in Australia, Canada and the United States airports,” the truth is that the operation of these digital towers raises doubts. In fact, tests in Spain are being carried out for years. In 2023 problems were already reported In the Vigo airport digital tower related to the imprecise detection of small aircraft. The project was approved in 2019, it was awarded in 2020 and until this year it has not been launched with the first flights. Something similar has happened in Menorca, where it is also being tested with a digital tower that At the end of 2022 he also reported problems security This air control system It should be underway in 2021 But for now he has not exceeded the evidence and has ended up being Vigo the city that has been awarded the first “digital control” of a flight in Spain. Joy, yes, has lasted four days. Photo | Enrique Dans and Aena In Xataka | We have been waiting for years at airports for years. Tiktok’s “airport theory” believes that it has been a mistake

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

by

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

An American physicist has found a shortcut to get to Mars in 90 days. It is key to surviving radiation

by

The long flight will be One of the many risks that astronauts who travel to Mars in front. SIX TO NINE MONTHS Broken the safe radiation limit that NASA establishes as acceptable: 600 msv. The problem would be forgotten if you could get to Mars in just 90 days. And you can with current technology, according to recent research. Conventional chemistry, record times. The physicist Jack Kingdon, a researcher at the University of California, has published in the magazine Scientific Reports A proposal that breaks with the provisions of trips to Mars. Normally, a flight to the red planet requires between six and nine months, which raises multitude of challenges for exposure to radiation. With Kingdon’s trajectory, 90 days per path would suffice. The most surprising thing is that their calculations are based on the classic method to optimize interplanetary trajectories (Lambert’s problem) and do not depend on futuristic engines, but on a current chemical rocket: the Spacex starship. Two crew and four loading ships. The proposal is a monumental scale. The mission to Mars would require six ships: two crew and four loads that would travel separately. To put them on the route, they would take about 45 Starship pitches within two to three weeks, a rhythm that, although ambitious, fits with Spacex’s plans to massively climb their operations. A gas station in space. The real logistics challenge would occur in the low terrestrial orbit. There, a starship-cistern fleet (ships dedicated exclusively to transport fuel) would perform a complex dancing of reposses: The two manned starship would need about 15 reposses each to load the 1,500 tons of propellant that will allow them to take the rapid trajectory. The four load starship, aimed at carrying the equipment and supplies, would receive only four reposses each and would be sent to Mars in a slower and lower energy consumption trajectory. The shortcut. Once full of methane and liquid oxygen, the two crew ships would turn on their engines to escape the earth’s orbit. They would cover a high -energy Lambert type trajectory required by an ΔV ≈ 4.6 km/s, which translates into a 90 -day flight time. Just before being captured by the severity of Mars, the ships would make a key ignition to stop, reducing their input speed of about 9.7 km/sa about 6.8 km/s. The Martian atmosphere would be in charge of dissipating the rest of the energy by aerocapture, a maneuver in which the ship “brushes” the atmosphere to stop without spending fuel. Finally, a brief ignition of the engines would allow a propulsive landing on the surface. The study demonstrates that this scheme is mathematically possible for the 2035 launch window, but it depends on Spacex dominating two critical technologies: the cryogenic orbital refueling on a large scale and hyperbolic aerocapture. And the return? An even more complex plan. If the idea is to return, the mission becomes much bold. First, a fuel production plant should be established on Mars (As Sabatier reactors) to manufacture methane and oxygen from CO₂ and the ice of the planet. The return plan implies that the manned ship take off from the surface of Mars and entered orbit. There, the load ships, which arrived previously, would also take off to act as cisterns in the Martian orbit, transferring all the necessary fuel to the manned ship for its 90 -day trip back to the earth. Not everyone shares optimism. The study identifies a viable return window in 2037. However, not everyone shares optimism. The own Paper recognizes that his proposal collides with the vision of agencies such as NASA, which has historically shown preference for nuclear propulsion For fast missions to Mars, a technology that, according to the author of the study, still has a low maturity and great regulatory obstacles. All this, of course, whenever the goal is to return. Recall that Elon Musk’s idea is to send robots first and then volunteers to build a self -sufficient city on the red planet.
