Spain has more and more problems with the drought and criminal networks have begun to realize it

This story begins with a civil guard couple in civilian clothes chasing a tanker truck. They have been following trucks for months, they have checked thousands of livestock farms and, finally, they are about to find something. With 50 million liters of something. The initial track. More than a hundred residents of a district of Lorca denounced last year that there was an entire network selling water tanks to supply agricultural operations. It is nothing new: the Civil Guard has numerous investigations underway into the inspection and control of water use. Therefore, SEPRONA started to investigate the matter. And what have they found? The surveillance device located the tanker truck filling point: it was a well without authorizations for use and without a volumetric counter or any other type of measuring instrument. It seemed difficult to know the number of liters extracted. However, as the company pretended to be legitimate, the Civil Guard has been able to document that, during the last 18 months, 56 million liters of water had been sold for a value of at least 275,000 euros. This is only in the last 18 months: the armed institute believes that the illegal use of the well may have lasted several decades. Just one case out of a million. Over the last few years We have been talking about dozens of people investigated, detained and convicted due to illegal irrigation: in 2023 alone, hundreds of millions of cubic meters of water have been extracted illegally. The problem is real: so real that the Malaga water company has even hired private detectives to monitor employees, suppliers and customers. However, the key to this is not what has already happened. The key is what is going to happen. The list of threats is enormous. Climate change, overexploitation of aquifers, intensive agriculture, inadequate water management, forest fires, deforestation and population growth… Spain has a problem with water and that problem is not going to stop growing and growing. In this context, robberies are going to become more frequent and common. And that’s saying a lot: according to WWFthere are more than 500,000 illegal wells. But no one can be surprised. After all, there is a high financial incentive and relatively low penalties. Most cases they end, in fact, in fines and that is an excellent breeding ground for a huge problem.

I have tried the world’s first rolled laptop. Just get back to him to realize that it makes a lot of sense

Two years ago, Lenovo showed at the MWC a concept of roller laptop of the most curious: His screen expanded to convert a conventional laptop into one with vertical screen. We did not know if that device would see the light at some point, but as the folding laptops did, In the end he did. In the CES of this year, Lenovo confirmed that this rolled laptop was no longer a concept and became a commercial product. He was baptized as Lenovo Thinkbook plus gen 6 and today, finally, we have had the opportunity to try it first hand. Because? That is a question that is worth asking, why an enrolly laptop? The answer, luckily, is simple: having a laptop with a large screen is fine, but having a large screen with more vertical space is wonderful if we work with documents (text or spreadsheets), texts or code. The attempts to date had been shy, with laptops that left the 16: 9 format for Bet on the 3: 2. Lenovo has gone a step further. Rolled is a more or less conventional computer | Image: Xataka But unrolled is another story | Image: Xataka How is? At first glance it is a conventional portable device, only that the screen is somewhat more square than normal. When the panel is rolled, it is 14 inches and has a resolution 2,000 x 1,600 pixels, that is, 5: 4 format. By clicking a button (or gesture with the hand that does not finish going fine), the laptop is displayed up to 16.7 inches, the 2,000 x 2,350 resolution pixels and an 8: 9 format. Basically, a 50% larger screen. The third button starting on the right in the upper row is the one that goes down and uploads the screen | Image: Xataka The laptop takes about ten seconds to complete the up or down cycle. The screen, of course, is hidden under the keyboard and unwinds thanks to engines that, everything is said, are heard slightly. It is not an unpleasant sound or that will be distracted, much less, but it is there. However, I must say that the contact took place in a crowded room of people, so I had to approach a lot to notice the noise. Hypnotiza. The truth is that it is easy to get dumbfounded seeing how the screen goes up and down. I will not affirm or deny having been turned on by clicking the button every ten seconds like a child with a new toy. It is one of those technologies that attract attention and that suppose a breath of fresh air in a mature product category in which innovation usually goes inside. Even more in the AI ​​PCs era. Detail of the roller mechanism | Image: Xataka And how much does it endure? When the durability question, from Lenovo they explain that the roller mechanism endures 20,000 cycles. They are about 11 years at the rate of five daily cycles. In this case, however, it must also be taken into account that the screen is not only enroll and unwinds, but also folds when we close the laptop. Lenovo ensures that the panel will endure 30,000 opening and closing cycles. Anyway, in a contact as preliminary as this is not possible to confirm this. This is how the laptop is seen from behind when it is completely unrolled | Image: Xataka The wrinkle. One of the great evils of folding mobiles is the wrinkle of the fold. Although manufacturers make all kinds of juggling to avoid or reduce it, such as making a drop -shaped fold, the reality is that it remains visible and notable to touch. In the case of Lenovo laptop is exactly the same. The wrinkle shows and looks. Not only is it seen, but it causes flashes when looking at the screen from certain angles. In front, however, there seems to be no problem. In what angles, the wrinkle is more or less visible | Image: Xataka A system that feels robust. Although the device rises and that the part that rises is thinner the upper area, the device does not transmit a sensation of fragility. It does not give the feeling that we will leave if we put it vertically and incline it. Moreover, the thickness of the laptop, being superior to that of a conventional laptop, is not as high as one could imagine. Yes, it weighs more and is thicker, but neither as much if we take into account that inside hides an roller screen and a deployment mechanism. An interesting change. As someone who is writing and reads a lot, a lot, a lot throughout the day, this type of implementations are interesting. On a few occasions I am doing Zoom-Out to a PDF to read more content or juggling to be able to better read something than, on a vertical screen, I could read without problem. This device solves that problem of a stroke, although it does so at a price well above what any laptop costs. Image | Xataka This laptop supposes, or could assume, a paradigm shift, in the way we understand the laptops. Getting that extra space is a fantasy for those of us who use the computer for productivity (not so much to play, there does not make too much sense). However, accessing this device is not something available to everyone. The price issue. The Thinkbook Plus Gen 6 Cuesta 4,199 eurosa price that surely leaves it out of the reach of most mortals. Does it solve having to load or install a secondary monitor to have flexibility? It solves it, partially at least, but it does it at a very high cost. The technology is impressive and seeing it in operation makes it win. The device is undoubtedly unique in its kind. Now he has the challenge of convincing users, and that is a flour from another sack. Images | Xataka In Xataka | “The AI ​​is not a … Read more

We are running out of beaches on the planet. And we don’t realize because they are filling them at an indecent price

There is something much worse than the appearance of algae either Fecal matter On the beaches. Even above of systematic “theft” That is being done on the coasts to continue raising brick, there is a silent reality whose ending is a scenario where, directly, we run out of beaches on the planet. That process is not just happening, we are spending a fortune at all. Global threat. I told this week The Financial Times In an extensive report. Rodanthein the Outer Banks of North Carolina, exemplifies the serious erosion suffered They have collapsed at sea. The problem, aggravated by more intense storms, strong tides and the rise in the level of the sea associated with climate change, is now amplified by a critical factor: the Sand scarcityresource that acts as a natural barrier to floods and temporal, but whose growing demand (especially For construction) it more expensive and limits its availability. The (no) trick. He method More common to stop erosion has been the “beach regeneration”, moving sand From other points, but in Rodanthe the initial cost would exceed 40 million dollarssomething unassumable for the municipality. This leaves as options the planned withdrawal of infrastructure or resistance until the waves dictate the end. Erosion as a structural challenge. Of course, there is a lot more. Cities such as Miami, Barcelona or the Australian Gold Coast face constant sand losses that threaten their beaches, vital for tourism and local economy. In Barcelona, erosion annual 30,000 m³ It is aggravated with each temporary, and although dikes and breakwaters have been added, the setback continues. In the Gold CoastCyclone Alfred in March started so much sand that left stretches of the retaining wall; Restoring the coast will cost three years and 40 million Australian dollars. The dilemma It is global: 10% of the population lives less than 5 km of the coast and urbanization slows the natural flows of sand, aggravating the problem. Rodanthe Steal sand. And yes, even scientists already They have warned On several occasions that sustaining beaches artificially is increasingly difficult and extremely expensive, and that in some cases it would be more sensible to allow the coastline to migrate inland, although socially and politically complex. Gold Coast The dilemma of providing sand. Regeneration It has advantages in front of rigid structures such as retaining walls, which can intensify erosion in adjacent areas. However, it is temporary and its duration depends on local geology, climate and human pressure: some beaches require new contributions every two years, others last a decade. In the United States, where it has been applied for a century, they have been treated almost 600 beachesreaching a maximum of 50 million m³ in 2019. The problem? That the search for proper sand It is complicated: In North Carolina, local reserves are exhausted, in Miami transport is used from inside, and environmental objections, such as marine habitats, delay projects. Plus: Powerful storms can erase millionaire investments. Perspectives and answers. In places with moderate erosion or abundant reserves, such as the Netherlands, regeneration is a State policy: The country invests the 0.3% of your GDP Annual in flood risk management and has 12 million m³ of sand available every year, sufficient to protect entire cities. On the other hand, in areas with severe erosion and overflowing costs, planned withdrawal can be the only viable output, implying controlled expropriations and demolitions. The Times told that in Rodanthe, the National Parks Service acquired and demolished two houses valued in millions to return the land to public use, but There are no funds For more purchases. Many residents, aware of living in the “land of changing sands”, assume that the sea will gain ground and prepare to sell when the water reaches wetlands. Battle against time (and economy). In short, the Sand scarcityits increase and the increase in coastal erosion draw a future in which to keep the current beaches looks like it is unfeasible for many communities. Although Regeneration It remains the preferred option to protect local properties and economies, its physical, financial and environmental limits. rethink strategies. The dilemma between spending more and more to contain the sea or yield terrain to nature will mark the future of much of the inhabited coasts, and the margin of maneuver is narrowed as the climate and the demand for sand accelerate the process.

We had to observe 4,000 supernovae to realize that something does not fit the explosions of the white dwarfs

Approximately a century ago we realized that the universe was not static but extended. Some theories even estimate that it does it at increasing speeds, but measuring this speed has become A major headacheas much as explaining the mechanisms that underlie this cosmic inflation. But maybe we are doing too many turns to the matter. Not so predictable. A study has observed That the supernovae associated with the white dwarf stars are not as predictable as we believed. The study presents us with a problem, and that is that the role of these explosions as markers of the cosmic distance is staggered now. Star milestones. Regular and predictable cosmic objects and events are of great help for astronomers when analyzing a vast and diverse cosmos. Know what intensity an object or a distant event shines opens the road to precisely calculating your distance based only on the intensity with which it shines in our sky. That is why these supernovas had been useful for calculating distances and with it the changes in the distance over time, that is to say the speed. The speed at which the objects of the cosmos move away from each other. Explosions of the most varied. The new study has revealed that supernovae associated with White dwarfs They are not in this group of regular cosmic events as we believed. Through its observations, the team found “multiple and exotic ways” in which white dwarfs could explode. These included collisions between two stars and star cannibalism in binary systems. “The diversity of ways in which white dwarfs can explode is much greater than it was previous And until years later ”´, pointed in a press release Kate Maguire, co -author of the study. 4,000 Supernovas. The finding was possible thanks to the use of tools capable of detecting very faint signals and the accumulation of a large amount of data for the sample. The team resorted to the data of the ZTF survey (Zwicky Transient Facity), From which they obtained information from a total of 4,000 supernovae, a sample, they explain, much greater than those previously compiled. “Thanks to the unique capacity of ZTF to scan the sky quickly and deeply, it has been possible Maguire added. The details of the study were recently published in a special number in the magazine Astronomy & Astrophysics. Dark energy. The finding is at the same time a problem and it is that if we lose one of the tools used to calculate the distances in the cosmos. In spite of this, it is great news since knowing that the outbreaks of white dwarf the one that moves away from us.
