The US has been looking from space for years at a huge brown ribbon in the Atlantic that goes from Mexico to Africa that should not be there

The blue planet looks very different from space. We have internalized things like that the Chinese Wall is seen and it is not true: what is appreciated They are the greenhouses of Almería. Or a great old man desknown as the Great Dam of Zimbabwe. And for a few years now, NASA satellites they have been registering the presence of a brown stripe that extends across the Atlantic Ocean. It’s not a big brown island or a continent, but it looks like it. What is that “brown continent”. It is a mass of brown algae that, according to research from the Harbor Branch Oceanographic Institute and Florida Atlantic University in whose last record It weighed 37.5 million tons and surpasses the 8,000 kilometers in length, more than from New York to Madrid. And it has a name: the Great Sargassum Belt. Context. He pelagic sargassum It is a seaweed that historically has always lived confined to the Sargasso Sea. However, since 2011 NASA has been documenting its expansion into the open sea until what it is now: a brown strip that by the end of 2024 left the Gulf of Mexico and spread until it reached the coasts of West Africa. This phenomenon is actually a huge accumulation of algae that reappears almost every year with one exception: 2013. The Great Atlantic Sargassum Belt is bigger than ever: evolution documented by NASA Why is it important. Because this stratospheric mass of algae is not only spectacular from a visual point of view: it has repercussions on the marine ecosystem, destroys beaches and even contributes to accelerating climate change. It is also an ecological alarm signal for the Atlantic. According to Dr. Brian Lapointelead author of the review of changes in pelagic sargassum and professor at FAU Harbor Branch, explains that it even caused the emergency shutdown of a Florida nuclear power plant in 1991. Why are they growing like foam?. Lapointe and his team have been investigating the evolution since the 1980s and have found that the nitrogen content in brown algae has increased by 55% between 1980 and 2020; the nitrogen/phosphorus ratio also increased by 50%. This change has occurred because brown algae no longer only feed on natural nutrients from the ocean, but also receive nitrogen and phosphorus from land thanks to human activity, such as agricultural runoff or wastewater discharge. The result is uncontrolled growth. Sargassum is transported by ocean currents, especially in floods from the Amazon, towards the Atlantic. There it thrives thanks to that extra supply of nutrients. An unaesthetic and harmful stain. Brown algae per se are not harmful and in fact, they serve as habitat for different species. However, its enormous presence has altered the ecosystem. Upon reaching the coasts, they begin to decompose, thus releasing hydrogen sulfide, a toxic gas that damages coral reefs, reduces the oxygen present and emits greenhouse gases. What can we do. In short: stop feeding them. After this exhaustive monitoring, the research team warns that humans should reduce nutrient runoff from the coast since, if this continues, more Great Sargassum Belts could appear throughout the ocean.

Verdeliss’s latest challenge reminds us that impossible challenges are huge business

Before we get into the matter, let me ask you an indiscreet question: What did you do between seven in the afternoon on Wednesday and the same time on Thursday? Most likely several things, including eating, sleeping, and stretching your legs. Of all of them Estefanía Unzu, better known by her alias ‘Verdeliss’he only did the last one. And in an unorthodox way. During 24 hours the influencer He dedicated himself to running on a treadmill installed behind a shop window in Madrid. It is the umpteenth proof of two trends that they walk run hand in hand: business and the fever generated by impossible challenges, a field that Verdeliss know well. What has happened? If in the last few hours you have stopped by the Decathlon store in Nuevos Ministerios (Orense Street, Madrid) it is quite likely that you have been surprised. On Wednesday the 25th at 7:01 p.m. in its window you could see a treadmill with a runner taking strides. At 2:00 a.m. the image was identical. And at 6:59 p.m. on Thursday the 26th, the same thing happened. The surprising thing is that during all that time (the 24 hours from 7:00 p.m. on Wednesday to 7:00 p.m. on Thursday) the person who ran on the treadmill was always the same: Verdeliss. His balance: 24 hours of walking and more than 250 km. Why did he do it? Advertising. The challenge is part of the campaign orchestrated by Decathlon to promote the sneakers Kipride Maxof Kiprunthe brand with which the French chain aspires to expand its space in the growing business athletics and amateur running. In fact, the company has been in charge of giving visibility to the Verdeliss challenge on its networks, with videos, photos, interviews with passers-by and of course to the influencer herselfwho before starting to run assured that his objective is to test his limits. The underlying purpose: to take advantage of the challenge to give notoriety to the new Decathlin sneakers and provide them with a place in a hypercompetitive market, in which large multinationals such as Adidas or Nike work in different price ranges and frequently launch promotions. Kiprin introduced the Kipride Max ago just a monthpromote them as daily training shoes “designed to offer the brand’s most cushioned and comfortable ride.” Why Verdeliss? Because of his public profile. Runners there are many. Influencers, too. Estefanía Unizo Ripoll (‘Verdeliss’) has however managed to gain notable fame. And it has done so with two ingredients: an unconventional profile and a commitment to extreme challenges like Decathlon. The influencer Navarre has 40 years, eight children and combines his love for extreme sports with his businesswoman facet and media figure (he reached go through Big Brother). Since he joined YouTube in 2008, his profile has also changed: from basically publishing family content he has turned towards extreme sports. If his name sounds familiar to you even if you don’t follow current events running maybe it’s because in 2025 he went for it World Marathon Challengea test that consists of seven marathons in seven days and different continents. And that is just one of the challenges he has conquered. Another is the national championship 100 km on the road. Why is it important? Because Decathlon’s challenge not only tells us about it. It also tells us a lot about the fever (and business) generated around impossible challenges. People like to explore (or see how others explore) physical limits, whether climbing skyscrapersjumping from heart attack distances either swimming and running enormous distances with hardly any breaks. Behind many of these initiatives there are sponsorships (also campaigns with a more or less solidarity approach) and above all a huge media exposure for those who star in them. Verdeliss, for example, adds some 1.6 million of followers on Instagram and others 2.1 million on YouTube. The organization of extreme events also opens a business avenue: without going any further, participating in the World Marathon Challenge requires paying tens of thousands of euros. With yesterday’s campaign, Decathlon manages to position itself in a hypercompetitive market and the influencer (beyond the promotional agreement itself) feeds her image as an athlete capable of conquering extraordinary challenges, traveling 255 km in 24 hours. In the background there is another debate: to what extent facing challenges like this pushes the body to its limits. In the past Unzu herself has recognized having done “savages” and who does not seek to be “exemplary.” In fact, he even warns his followers: “Don’t do this in your house.” Images |Decathlon (IG) and Verdeliss In Xataka | The Winter Olympics leave Italy with a debt of 7.8 million dollars.

Mercadona suppliers have invested 1.7 billion euros. That gives you an idea of ​​what a huge business it has become.

when you want present your model Mercadona’s business strategy usually cites five pillars: “the boss” (the word used to refer to customers), its staff, society and capital. The fifth is his wide network of suppliers. That the Valencian chain includes them on that list is no coincidence. If it has managed to lead the sector until it has gained a business share that is already close to 30%, it is thanks largely to its bet on white labela wide catalog of articles impossible to articulate without a “industrial cluster” with 2,100 suppliers. As Mercadona grows they do it too, but that link is not free. In order not to lose step, they are forced to invest millions. One figure: 1.7 billion. The data has revealed it Expansion. Last year, Mercadona suppliers made investments in Spain and Portugal worth 1.7 billion euros. The figure is not only interesting for its volume, it is also interesting when put into perspective: it represents 31% more than the previous year, when the sum of investments amounted to 1,300 million. If compared to 2023, when ‘only’ 500 million euros were mobilized, the increase in investment is much greater, close to 240%. Of course, not all suppliers have spent the same nor do all the projects in which they have invested have to be 100% focused on Mercadona, although it is true that the chain is the main client of some of its suppliers. Who has invested the most? Mercadona has not yet presented its 2025 report, but we do have that of the previous yearwhich details the suppliers that mobilized the most investment and generated the most employment. At the head was Casa Tarradellas, which supplies Mercadona with ready-made pizzas and fuets for the Hacendado brand. In 2024 the Catalan company invested 104 million to build two new factories, dryers and production lines. The published data by Expansion show that in 2025 it once again led investment in the Mercadona supplier ecosystem, with the mobilization of 117.6 million. At the beginning of last year the firm presented a new mill for wheat flour in Gurb (Barcelona) that required 25 million of euros and throughout the year it also promoted a storage center of species. In 2024 Casa Tarradellas achieved increase 12% its profits to reach 38.4 million euros, consolidating the positive trend already registered in 2023. The result was largely possible due to the increase in income. An investment cluster. The list The greatest investment effort is completed by companies such as Vall Companys (70 million euros), Incarlopsa, Avinatur, Essity and Cañigueral, all four with investments close to 60 million, Covap (42.5 million) and Entrepinares (27 million). Names such as Familia Martínez, Huevos Guillén (50) and Elaborados Naturales (40) also stand out. Not all of that money has had to be allocated to projects focused on supplying Mercadona, but a review of the reports deposited in the Commercial Registry reveals that the supermarket chain has become the main client of its suppliers. In some cases the company founded by Roig actually represents more than 50% of all his income. “Joint planning”. The data is interesting because it does not only tell us about the resources that Mercadona suppliers have dedicated to strengthening their infrastructure and productivity. It also suggests that these companies are forced to make this effort to keep up with the Valencian chain, which in 2024 increased its turnover by 9%, to exceed the 38.8 billion euros. Looking ahead to 2025, it expected to continue growing and reach 40.1 billion. Although Mercadona has not yet presented its report for the past year, we do have studies that show that it has achieved increase your quota of business, moving away from rivals such as Carrefour or Lidl. As its sales grow and its catalog of private labels and ready-to-eat foods triumphs, the Valencian firm needs to rely on its “industrial cluster” of suppliers. Hence the urgency for them to strengthen their production capacity. “These investments are possible thanks to trust and joint planning,” they explain from Mercadona when remembering the 1.7 billion mobilized. Investment… and something more. That these companies are willing to dedicate millions and millions of euros to modernize their facilities, gain production capacity or expand is explained by a very simple reason: keeping up with the Valencian chain has become quite a lucrative business. Recently Five Days he wondered how the companies that supply it with products are doing and, after investigating the Commercial Registry, it found out that in 2024 the 20 main suppliers of the chain increased their sales figures by 18% to exceed 12,000 million euros. In total, aggregate profits grew by 5%, exceeding 360 million. Curiously (or not) at the top in billing volume were Casa Tarradellas, Incarlopsa, J García Carrión and Covap, with sales increases ranging from 12 to 29% between 2022 and 2024.

“We didn’t expect this.” A Ukrainian drone has revealed a Russian arsenal in a warehouse, and the surprise has been huge: the missiles are animals

From the early stages of the Russian invasion of Ukraine, when tanks were advancing while logistics columns were bogged down and fuel was scarce, the war began to reveal an uncomfortable paradox: the more modern it became in the skies, more “medieval” It was done on the ground. In fact, in that space where drones, satellites and trenches coexist, the return of solutions from the past apparently overcome was an early sign that the conflict was going to be, above all, a test of resistance. The latest Ukrainian discovery has confirmed that the wear and tear is tremendous. The return of the war of attrition. The irony is that the war in Ukraine has been shedding any illusion of modernity to return, as the days go by, to brutal logic of wear, one in which the quantity and capacity to take losses They weigh more than any technological “game changer”, and where the Russian army, pressured by the massive consumption of material and men, is beginning to show obvious signs of logistical exhaustion. On the southern and eastern front, the shortage of armored vehicles and modern systems is no longer hidden with silence, but is manifest in improvised solutions reminiscent of conflicts from another era and centuries, while Moscow insists on maintaining constant pressure on Ukrainian defenses at any cost. Cavalry in the 21st century. This wear and tear became visible at the beginning of 2026 when Ukrainian units detected and neutralized Russian assaults carried out on horseback, a tactic that seemed banished from modern warfare but that reappeared in sectors such as Oleskiivka in response to lack of means conventional. We are talking about small assault groups that advanced mounted, supported by prior reconnaissance, in infiltration attempts that ended up being aborted by drones and fire defensive, leaving such an absurd image (and repeated) as revealing: many horses survived, but the soldiers did not, and the Russian army confirmed that it was willing to resort to any available resources to sustain its offensive. The drone and the impossible arsenal. Now, the scene What finally condensed this drift came several weeks later, when a Ukrainian drone sneaked through the destroyed roof of a hidden warehouse, several kilometers from the line of contact, with the usual expectation of finding ammunition, fuel or military vehicles. What happened gives an idea of ​​these four years of slow war that has worn down both sides. Instead of artillery and technology to advance, the camera showed something that looked like something out of a rural garage: aging civilian cars, motorcycles from another era, and saddled horses, an “arsenal” as unexpected as it is eloquent of the state of the war in many areas. The message. “We didn’t expect to see this. It was really unusual,” said the drone pilot. to the Insider mediumspeaking on condition that he only be identified by his callsign “Cosmos.” “We were hoping to find some armored vehicles,” he added. He video It went viral because it summarized in seconds the real state of Russian logistics, but also because it demonstrated that those animals were not an isolated anecdote, but part of a system that already uses cheap and expendable media to move and attack under the constant threat of drones. Russia and the logic of sacrifice. For the Ukrainian commanders, this discovery is neither trivial nor a simple curiosity, but rather proof of a way of waging war based on accepting massive losses of material and personnel, replacing armored by civilian cars and horses because they are easier to replace. This logic, which prioritizes the attrition of the enemy, even if the cost is enormous, explains why Moscow continues to advance slowly, launching assaults with many times obsolete or improvised in regions such as Donbas, even when the monthly casualty figures, according to NATOreach levels that are difficult to sustain. If you will, the drone that expected to find missiles and found animals ended up portraying, better than any report, a war that moves backwards while consuming everything at hand.

North Korea believed the threat was miles from its border. A video has revealed that it is a few meters away with a huge warhead

For years, North Korea has built your security on the idea that the most dangerous thing came from afar and could be seen coming in time. But on the peninsula, threats do not always come from the other side of the world: sometimes they develop much closer than anyone imagined. A “monster” missile. a video has revealed that South Korea has begun to operationally deploy the Hyunmoo-5its largest ballistic missile to date and one of the most peculiar in the world due to the combination of size and mission. Although it remains shrouded in secrecy and there are no publicly confirmed test launches, its input in units indicates that Seoul already considers it a real instrument of deterrence. A weapon designed for an extreme scenario on the peninsula, where the problem is not just attacking, but hitting what is buried, protected and designed to survive. The key: the head. What it places to Hyunmoo-5 In a category of its own is its warhead gigantic penetrationmuch heavier than that of usual conventional missiles. Where it is normal to carry loads of less than a ton, here we are talking about a block that can be around several tons, with an important part dedicated to dense metal and structure to pierce before detonating. The logic is simple and we have seen it before in the United States MOP: enter the ground at enormous speed, break through like a kinetic hammer and then explode once inside, attacking bunkers, command centers, warehouses and shelters designed to withstand traditional attacks. Ballistic bunker-buster. In terms of effect, it is reminiscent of bunker buster bombs launched from a planebut with a decisive difference: here it is not falling from a bomber at subsonic speed, but rather hits like a ballistic projectile at speeds close to hypersonic or directly hypersonic. This multiplies the penetration capacity by pure impact energyeven before counting the explosion. It does not make the weapon “nuclear,” because the type of destruction is different, but it does create a conventional tool with the power of entry and demolition that seeks to get closer to what a regime fears most: losing its underground shelters. Ceremony celebrating the 65th anniversary of the Armed Forces of the Republic of Korea The mystery of scope. The huge warhead penalizes the range, and that is why many estimates They place their radius of action around about 600 kilometersmore typical of a short-range missile despite the size of the set. For South Korea that is not a problem, because the priority objective is close and it’s concrete: Hardened facilities in North Korea. Still, if the load were lightened, it could reach much greater distances, even entering intermediate-range missile parameters, opening the door to broader regional readouts. Total design freedom. For decades, Seoul developed missiles under agreed limits with Washington, first very strict and then increasingly relaxeduntil those guidelines disappeared completely in 2021. That change was not symbolic: it came at the pace of North Korea’s advance in missiles and nuclear weapons, and left South Korea with room to create heavier, more capable systems with greater range options. Hyunmoo-4 had already raised the bar with a powerful charge, but Hyunmoo-5 represents the definitive jump to the idea of ​​“demolition power” as a main feature. The three-way strategy. Plus: the Hyunmoo-5 is integrated into the South Korean scheme designed to avoid or respond to a North Korean nuclear attack, with three pillars that complement each other: a preemptive strike plan on nuclear and missile capabilities if deemed inevitable, an air and missile defense to intercept launches, and massive conventional retaliation against leadership and strategic infrastructure if the North strikes first. On that board, the missile serves both to punish and to decapitate capabilities, because its specialty is attacking what the adversary hides underground to guarantee its continuity. Deterrence and escalation. They counted the TWZ analysts that the South Korean bet aims to maintain a “balance of terror” with increasingly forceful conventional means, but it also fuels an uncomfortable debate about the future. If Seoul one day decided to pursue a nuclear arsenal of its own, a missile from this family would be a natural candidateand a nuclear charge would also be much lighter than the current conventional one, which would expand range and flexibility. Meanwhile, the mere existence of Hyunmoo-5 already serves as an unmistakable message: even without crossing the nuclear threshold, South Korea wants the ability to open any relevant bunker and force Pyongyang to assume that his depth no longer guarantees security. Beyond Pyongyang. In public, South Korea frames these weapons as an answer to North Korea, but the regional background weighs more and more. Have a missile potentially adaptable in range and with a devastating payload add margin facing scenarios where the threat is not only from North Korea, but also from nearby powers such as China or Russia. The idea of ​​​​increasing their survival and employment options with future naval platforms is even contemplated, following the trend global from “arsenal ships”because in deterrence it is not enough to have the weapon: we must also guarantee that it will remain alive when the time comes to use it.

The Vitruvian Basilica is the “holy grail” of Roman architecture. Also a huge enigma that we have finally solved

If there is one thing that abounds in the presentations of archaeological finds (no matter where, when or who makes them) they are superlatives. Each discovery is the most important, the definitive one, the last missing piece to complete the puzzle. Another thing is that it really is like that. In the province of Pesaro and Urbino (Italy) the authorities they just announced a finding in which the opposite occurs: yes, there are superlatives, but they fall short. In the end, what they have unearthed there is neither more nor less than the “holy grail” of Roman architecture. In a stroke of luck, archaeologists have found the basilica erected 2,000 years ago by Marcus Vitruvius, which concludes a search for more than five centuries. What has happened? That Italy has put an end to a 500 year adventurethe time that archaeologists, architects and historians have been searching for perhaps the “holy grail” of Roman architecture: the legendary Vitruvian Basilica. Scholars placed it in Fanum Fortunae (current city of Fano) and for decades they probed its soil in search of vestiges or at least some indication. In vain. things changed about three years agowhen during the renovation works of the market square they found themselves (shortly half a meter deep) some remains that, we now know, belong to the basilica. “Millimeter correspondence”. What we have found under the cobblestones of Fano are Roman columns. So far nothing exceptional considering that we are talking about an ancient coastal city in the Marche region of Italy. The curious thing is that these vestiges fit closely with the description that Marcus Vitruvius left us of the basilica in his famous treatise. ‘Of Architecture’. The columns, their arrangement, the shape and layout of the nave coincide. The “definitive confirmation”, clarify from the Italian Ministry of Culture, arrived after the discovery of a fifth pillar that confirms both the position and orientation of the property. A planimetric reconstruction based on the description left by Vitruvius finally provided the guide. The coincidence is so precise that the authorities speak of a “millimeter correspondence”. “Imposing structures”. “The columns, around five Roman feet in diameter (147-150 cm) and about 15 meters high, rest on pillars and pilasters that supported an upper floor,” points out the Italian Government, which recalls that in 2022 experts were on the trail after discovering some “imposing masonry structures and marble floors” on Via Vitruvio. The confirmation that the remains belong to the old basilica does not complete the work. In fact, Cultura is already advancing that it will continue researching with the support of community funds. “Everything necessary will be done to recover and promote this exceptional find,” guarantees the regional president, Francesco Acquaroli. “Like Tutankhamun’s tomb”. During the presentation neither Francesco Acquaroli, nor the Minister of Culture, Alessandro Giuli, nor certainly the mayor of the town, Luca Serfilippi, spared praise (and superlatives). “The column behind us changes the history of the region. It is a discovery comparable to that of Tutankhamun’s tomb,” celebrated the regional leader. Giuli has used similar effusiveness, for whom the location of the mythical Roman basilica, erected ago two millenniabrand “a before and after” in archaeological history. “History books and not just journalistic chronicles will document this day and everything that will be studied about this exceptional discovery in the coming years. The scientific value is of absolute caliber,” he emphasized the Minister of Culture. “The vestiges discovered clearly demonstrate that Fano was and is the heart of the oldest architectural wisdom of Western civilization.” Is it so relevant? Whether the discovery of the Vitruvian basilica is comparable to that of Tutankhamun’s tomb may perhaps be discussed, of course what is undeniable is that it is one of the great archaeological news of the year (and that at the very least). The reason is not only the value of the building but that of its creator, Marcus Vitruvius (1st century BC), architect, engineer, treatise writer and author of ‘Of Architecture’a fundamental manual to understand Renaissance architecture. In his treatise Vitruvius addresses the three axes that would mark architecture for centuries: firmitas (firmness), utilities (functionality) and venustas (beauty). His work influenced, among others, León Battista Alberti, Andrea Palladio and Leonardo Da Vinci, who was inspired by its proportions to create one of the most iconic (and recognizable) drawings of all time: the ‘Vitruvian Man’. In ‘De Architectura’ the Roman architect does something else: he describes in detail the basilica that has now been found (finally) in Fano, a project in which was directly involved. In fact, the Ministry of Culture remember that it is the “only building attributable with certainty” to the Roman writer. Now we no longer need to imagine it.

Eric Schmidt, former CEO of Google, is building a huge space telescope. The question is not how, but why

If someone today wanted to build something like a new Hubble, it would make sense to think of years of reports, reviews and committees before the first piece of hardware is even manufactured. However, that logic has just been broken with an unexpected announcement: Eric Schmidt, former CEO of Google, and his wife Wendy have put on the table his own money to power not one, but four telescopes, including a large-scale space observatory. The move not only challenges the sector’s inertia, but raises a question deeper than budget or technology: what exactly is a former Silicon Valley executive pursuing by wading into the heart of modern astronomy. This is a project promoted by the Schmidt Observatory System, it seeks to cover everything from the deep sky to the detailed study of transient phenomena. A change of model. Currently, telescopes are generally in the hands of public agencies and academic consortia. Building ever-larger mirrors and then putting instruments into orbit turned astronomy into a matter of national budgets. The Schmidts’ entry into this arena suggests that, with new technologies and another way to finance risk, that historic balance could be starting to shift again. Risk, speed and open science. The approach behind the observatory system is not to compete with space agencies, but to cover the space left by their own processes, which are long, conservative and highly conditioned by public budgets. The Schmidts seek to finance concepts that have already been imagined by the scientific community, but that rarely overcome the barrier of official financing due to their level of risk or the deadlines they require. The piece that gives meaning to the whole and that really makes the difference is Lazulithe only one of the four projects that will leave Earth. It aims to cover a wide range of science, from transient events lasting minutes or hours to the detailed study of exoplanets, with a level of flexibility that large public observatories cannot always offer. Further, more agile. One of the clearest breaks between Lazuli and Hubble is where it will operate and how. While NASA’s telescope orbits about 500 kilometers from Earth, Lazuli will be placed much further away, in an elliptical orbit that should give it a clearer view and allow for fast and continuous data linking. Lazuli Space Observatory In the official description, Schmidt Sciences frames this operation in a “lunar-resonant” orbit. Added to this is a larger mirror, 3.1 meters compared to Hubble’s 2.4 meters, and an observation philosophy designed to react quickly to unexpected phenomena. One platform, several instruments. Lazuli is designed as a unique platform that integrates three instruments designed to cover everything from wide-field observations to the detailed study of exoplanets and transient phenomena. Wide-field optical imager with high cadence for photometric time series, 30′×15′ field of view and filters between 300 and 1000 nm Integral field spectrograph continuously covering 400–1700 nm, optimized for stable spectrophotometry and rapid sorting High contrast coronagraph to directly observe exoplanets and circumstellar environments, with contrasts of 10⁻⁸ and up to 10⁻⁹ after processing The era of array telescopes. Argus, DSA and LFAST They are not traditional telescopes, but rather distributed systems that take advantage of recent advances in computing, storage, and automated analysis. Instead of concentrating everything in a single structure, they distribute the collection of light or radio signals among tens or thousands of modules that are then digitally synchronized. This modularity aims to accelerate deployments and opens the door to observing the sky almost in real time, something fundamental for the astronomy of fleeting events. Render of the Argus Array (left), Deep Synoptic Array (right) Argus Array will bring together 1,200 optical telescopes in Texas to observe the northern sky almost continuously, with the idea of ​​being able to “rewind” what happened minutes or hours before an event such as a supernova. DSA, in Nevada and under the direction of Caltech, will deploy 1,600 radio antennas to map more than a billion sources and update its view of the sky every fifteen minutes. LFAST, for its part, will be installed in Arizona as a system of 20 80-centimeter mirrors aimed at large-aperture spectroscopy and the search for biosignatures, with a prototype planned for mid-2026. What the Schmidts have launched is, at its core, an experiment on the scientific system itself. Lazuli and his three colleagues on land aim to show that it is possible to build large-scale observatories more quickly and with an openness of data that does not always fit into traditional models. Whether that vision materializes will depend on factors yet to be determined, such as the final contractors, real costs or the feasibility of the schedules, but if it goes well, the impact will not only be measured in new discoveries, but in a new way of deciding what science is done.

There is a huge gap between what we think medical marijuana does and what it actually does.

Anti-inflammatory, analgesic, relaxing, sleep inducer, anti-tumor, anticonvulsant… It is not the definitive medication leaflet, these are just some examples of what I have found when searching for “medical marijuana benefits.” According to a survey in the United States and Canada, 27% of citizens have consumed it to treat anxiety, relieve pain and sleep better. What if it is not as effective as we thought? This is what UCLA has just concluded after an extensive study in which they have analyzed fifteen years of data. The study. We have known him through New York Times. This is a very extensive review in which a group of psychiatrists from the University of California has analyzed more than 2,500 articles published from January 2010 to September of this year. They have included clinical trials, meta-analyses and clinical guidelines and have prioritized those that are based on larger and more relevant samples. The beliefs. In recent years, cannabis has become popular after its legalization in the United States, where It already collects more taxes than alcohol. According to the survey we mentioned above, people who used for medicinal purposes did so mainly to relieve pain (53%), sleep better (46%), treat anxiety (52%) and depression (40%). The conclusions. The study is conclusive: there is a huge difference between what we believe and scientific evidence. The evidence is strong in very specific cases, such as loss of appetite associated with HIV/AIDS, chemotherapy symptoms (specifically nausea and vomiting), and some severe pediatric disorders that cause seizures. However, for other conditions, the studies analyzed did not provide conclusive evidence of its effectiveness. For example, in the case of pain, one of the most common uses, clinical guideline from the American Association of Clinical Oncology does not recommend it as a first-line treatment due to lack of evidence. For anxiety there is also no solid evidence on the effectiveness of THC, but CBD consumed orally did obtain more notable results in reducing anxiety. Risks. While the evidence on its effectiveness is doubtful in many cases, the evidence on the risks is more extensive. Marijuana is associated with the appearance of psychotic symptoms and anxiety, especially that which has a high THC content, increasing the risk of anxiety disorder by 19.1%. Smoking marijuana daily increases the risk of coronary heart disease by 2%, the risk of heart attack by 1.7% and stroke by 2.6%. Addiction. On the other hand, there is the issue of addiction. The study estimates that 29% of people who use medical marijuana have a substance abuse problem, especially those who smoke it. Speaking to the New York Times, the professor and expert Ryan Vandreystates that this explains the improvements in insomnia that many consumers advocate; It is not that marijuana makes them sleep better, it is that they sleep worse if they do not consume it due to their dependence on the substance. “If they stopped using cannabis for a month, they might notice an improvement in their sleep. But most never make it to that month because, after a day or two without sleep, they convince themselves that ‘this is the only thing that helps me sleep, so I have to keep using it,’” he says. The excuse. It so happens that many medical marijuana users do not have any medical prescription. According to one survey published this year77% of consumers declared using cannabis for medical purposes, but only 28% consumed on medical advice. According to Kevin Hill, one of the authors of the UCLA review, there are justified and effective uses of cannabis, but there is a huge group of users for whom medicinal use is the excuse to “rationalize their recreational use.” Image | RDNE Stock project, Pexels In Xataka | The positive (and quite predictable) effect of legalizing the sale and consumption of marijuana
