Having an AI browser that does things for you sounds good. Until a hacker uses it to steal all your money

by

Ask the AI ​​to make a summary of that article that you just saw in Reddit can be very expensive. It is what They just revealed Those responsible for Brave, who have discovered a surprisingly simple way to hack the browser of the perplexity comet to do not only what the user asks, but what an attacker has managed to convince him to do. The danger of leaving everything in the hands of AI is evident. What happened. Brave’s experts, a browser that competes with Chrome or Firefox and also has AI functions, wanted to analyze the risk of using an agetic browser like the one It offers perplexity right now with Comet. And what if they have done it. The browsers with ia promise a lot. Thanks to tools like Comet – Openai too has its chatgpt agentheir of Operator-, It is possible that the browser becomes a kind of digital butler and do things for us autonomously when visiting websites. Thus, you can summarize a news, tell you which song appears in that YouTube video, look for offers, answer emails or complete purchase processes. A priori the advantages are huge, but be careful, because there are also important risks. But be careful to let go of the steering wheel. However, delegating everything in the browser can raise a real threat to the safety and privacy of our data. If we trust them too much, these browsers may have access to all our data, since theoretically they will benefit from access to our email, but also to banking and financial data and even health. What happens if the amazing model or makes mistakes? Or worse: What happens if someone modifies the content in a malicious and invisible way for ia agents to follow malicious instructions? Having the AI. That is just what They discovered in Brave When trying a simple technique. They published a malicious comment on a Reddit thread, and then asked Comet to summarize the article. When they went to do it they verified how Comet did not know whether the content of that thread could or not contain malicious instructions: he simply met them and followed them. And in thread, as can be seen in the video, there were some simple instructions that stole the credentials of their perplexity account and even intercepted the verification code that the platform sent to the user to log in the service. Result: Automatic account by the attacker thanks to the AI. How the attack works. As Brave experts explain, the problem is that the way of hacking this type of browse is not hacking the browsers, but hacking the content, something that is very, very simple. The steps are the following: Configuration: An attack writes Malicious instructions in some content on the web. If you control that site, you can hide instructions using blank text if the background is also white, or in comments or other invisible elements. They can also do it directly “injecting” those instructions through comments in publications on social networks such as Reddit or Facebook. Activation: A user sails to that website and uses the browser with AI. If you do something simple as “Summarize this page“Or ask that certain information be extracted, these malicious instructions are activated. Injection: As the AI ​​processes the information on the page, see those malicious instructions and follow them. It is not able to distinguish whether the content has a malicious purpose or not, and considers everything as part of what you should do at the request of the user. Exploitation: these malicious commands and instructions indicate to the navigator’s tools to perform various actions, such as navigating the user’s bank account, Extract stored passwords In the browser or collect information to a remote server controlled by the attacker. Possible solutions. Those responsible for the study indicate that to protect themselves from these types of problems, agricultural browsers must first differentiate between what the user has asked for and what the user content is. The content of a website “should always be treated as non -reliable.” In addition, the browser with AI should necessarily ask for the user’s interaction to perform certain actions, how to access passwords or perhaps send an email. Restrict permissions to the agetic browser and make good use of Two -step verification systems “With mobile applications such as Google Authenticator, for example,” are also adequate ways to mitigate a problem that can put in many problems the deployment of these tools.

So much ice has melted in Greenland that the plankton has grown 40%. It is not good news

by

The Antarctica and Greenland have become two of the Climate change thermometers. The Ice loss in Greenland It is something that has been monitored for years because not only influences sea level: also in the Sinking of the seabed. It is estimated that Greenland’s glaciers have reached a point of no returnand its implications go beyond sea level. In fact, a recent NASA study He points out that there is a beneficiary of the thaw: the phytoplankton. And it is not good news. Short. A few months ago we commented that Greenland was getting greener. The estimates point out that, during the last 30 years, the region has lost 1.6% of its ice, which may seem little, but it is something equivalent to the Galicia area. The air temperature is about 3 higher Celsius degrees in the period between 2007-2012 than in 1979-2000, and That thaw It is causing a huge increase in fresh water. How much? According to the investigation of San José State University and NASA, of up to 266 million tons per year that are discharged into the sea, especially under the Jakobshavn glacier, the greatest in Greenland. It is the equivalent of 1,200 cubic meters of fresh water that are poured into the sea every second. As is fresh water, it is less dense and lighter than the salty, and what it does is like a whirlpool, dragging nutrients from the seabed to the surface. The study. These nutrients are mainly iron and nitrates, and it is phenomenal to phytoplankton. It is, however, an anomaly, and the researchers wondered to what extent that rapid growth of the plankton could affect the ecosystem. In it studypublished in Nature, detail how with the help of a model developed in the JPL and the MIT and using superoringers to accelerate the calculations, simulated the interaction between the water of the thaw, the nutrients and the phytoplankton. The greatest areas is where an increase in chlorophyll has been seen in recent years They have discovered that the growth of the body in the studied area increases between 15% and 40% in summer, at which time the maximum point of the thaw is given, thanks to those nutrients that the fresh water current sends to the surface. In total, NASA has observed That, between 1998 and 2018, the growth of phytoplankton in argic waters had increased by 57%. Consequences. On the one hand, that increase in phytoplankton can be positive for marine life, since it improves the basis of the ecosystem to be able to feed more animals, and also phytoplankton Atmospheric co -capture (that is not bad for us) To do photosynthesis. However, there is a paste: changes in temperature, chemical composition and water salinity can alter ecosystems. In the study they have not launched predictions about what will happen, but it is evident that it is a substantial modification of the marine properties of that specific area. Its conclusion is that those Changes in the Food Chain They can modify the composition of marine species, from bacteria to fish, affecting both the equilibrium of the ecosystem and fishing activities, which are a key engine for Greenland. Because phytoplankton is tiny, but it is the food of Kril and other small herbivores that, in turn, are the larger animal food baselike fish and whales. Only in Greenland? This study was carried out in a very specific area, that of the Jakobshavn glacier, but the results have similar implications for the more than 250 marine glaciers in the region and, possibly, for other glaciers that end in the sea in other regions of the world. Researchers comment that this simulation method is adaptable to other systems and that, therefore, it is likely that other areas where glaciers are pouring water into the sea They are also living, to a greater or lesser degree, a similar phenomenon, modifying ecosystems and affecting both fauna and fishing activities that are carried out in the area. Therefore, the thaw of glaciers is no longer that it affects only at sea level, but has the potential for alter the ecological balance of the regions in which it occurs. As they say, we were few and the grandmother gave birth. Images | POT In Xataka | 400,000 years ago all Greenland ice melted. The map he drew is not flattering

More and more voices think that keeping food in plastic is not a good idea

by

A kitchen that boards has a drawer up to numerous tuppers with the tapas on the other hand. Although it is not the only place, we open the fridge and find even more stacked: some keep the leftovers of noon, others contain freshly taken food from their original container. Behind this daily life – so assumed that goes unnoticed – hides an uncomfortable question: are we storing our food well? The plastic under suspicion. Light, cheap, resistant: plastic became the great ally of modern cuisine. However, recent studies call their safety when they come into contact with food. A BBC report He explained That thousands of chemicals are part of their composition and that some can migrate to food, especially when they come into contact with fatty, acid or hot foods. The problem is not only the food we keep, but also the use we give: the microwave, the dishwasher or the rayons due to repeated use accelerate the release of compounds. And microplastics. To them is added another invisible problem. As Delish magazine has pointed outtuppers release microplastics, tiny particles that have already been found in blood, lungs and even human placenta. A health problem. The debate about tuppers is not a simple kitchen detail: what is at stake is hormonal health. Many of the compounds that migrate from food plastics are classified as endocrine disruptors, substances capable of altering the balance of our hormones. The best known case is bisphenol A (BPA), used for decades in rigid plastics and linked to fertility and development problems. The European Food Security Authority (EFSA) recently reviewed its safety and reduced tolerable intake at a level 20,000 times lower than the previous one. Something similar happens with phthalates, employees to give flexibility to plastic and also associated with hormonal and reproductive alterations, As the BBC has detailed. Plans b. However, trusting alternatives is not a guarantee either. The Guardian He has warned that compounds used as BPA substitutes – the so -called BPS and BPF – have similar effects on the body. AND, According to a study cited by The I Papermore than 3,600 chemicals of plastic containers present in humans have been identified, many of them barely studied. Therefore, some expert voices are overwhelming. Lisa Zimmerman, from Food Packaging Forum, summarized it like this For the same medium: “If you care about your health, you should throw your plastic tuppers and use glass or steel.” The stations also influence. Beyond chemicals, summer heat adds another threat: bacteria. In statements collected by El Confidencialdietitian Judit Carreira, from the Sant Pau Hospital, explained that high temperatures favor food poisoning. Its advice is clear: transport the taperes in thermal bags or portable refrigerators, avoid exposing them to the sun and, above all, separating raw cooked in the fridge to prevent cross contamination. “When you return from the supermarket, the meat and the raw fish should be removed from the container and stored in a clean taper,” He has insisted. He also remembered the four basic food security rules: clean, separate, cook and cool. So, throw all my tuppers? It is not about emptying the kitchen, but of changing habits. Various media They coincide In a series of recommendations: Avoid reheating in plastic: although the container indicates “suitable for microwave”, heat accelerates chemical migration. Reserve them only for cold or dry foods, never for oily, acid or hot meals. Replace them if they are scratched, deformed or with persistent smell. Opt for glass, steel or ceramics for hot meals or prolonged conservation. Now, not all alternatives are perfect. Ceramics, although it is considered safe if it is certified, can be a problem in cases of artisanal productions. The mail reported a few months ago The case of a family of Getxo (Vizcaya) poisoned with lead after drinking for years of an enameled ceramic jug bought in Andalusia. Lead, prohibited in pottery since the 60s, can cause abdominal pain, anemia or neurological alterations. An easier life, at risk. It is true that tuppers have made our lives easier, but they have also exposed us to a chemical soup not yet known. Science still investigates the cumulative effects, but there is consensus on something simple: heat, fat and plastic do not combine well. Perhaps the true luxury of modern cuisine is not accumulating containers of all sizes, but choosing containers that take care of our health.

We have asked Renfe what alternatives we have to the cancellations of the AVE in Galicia. There are good and bad news

by

For sixth consecutive day, the high -speed circulation of the Galician corridor remains suspended. The service between Madrid and the Galician cities is provided only partially and in extraordinary frequencies. We have spoken with Renfe and consumer associations to know what their alternatives are. Sixth day without bird. Renfe cannot provide the high speed service of the Galician corridor as a whole. So The company itself confirmed it on its social networks but On its website Information about the latest news related to the railway situation between Madrid and Galicia is not found. No, at least, with a first glance. It is the result of the serious fires that are ravaging Zamora, León and Ourense, which They do not allow for sure to the high speed line. Given the impossibility of guaranteeing an improvement in them and, therefore, an opening of the line, Renfe confirmed almost at 11:00 am that all trains of today Tuesday, August 19, were suspended. Click on the image to go to the original tweet To (or from) Zamora. The solution that Renfe is giving is that passengers who prefer can travel from Madrid to Zamora or start their trip to the capital in the latter city, if it moves in the opposite direction. It is a patch that also requires adapting to Special schedules because the usual frequencies or schedules are not being fulfilled. Arriving in Galicia from Zamora or arriving in Zamora from the Galician community has already been in charge of the client. The latter is the one who has to look for life to take the train or reach its original destination. Something that, from Facua, they point out, should not happen. Buses? Jordi Castilla, Facua spokesman, explains that Renfe has the obligation to allow the change of ticket or its cancellation for free. Something that is already doing. However, it specifies that the company has to “relocate the person in an alternative environment without any cost.” From Xataka We have asked Renfe about this possibility and if they are valuing to include it in the next few days but we have not obtained an answer. Nor have those who In social networks they are asking Link Galicia with Zamora by bus since the main roads remains open. From Facua they emphasize that if the suspend and Renfe service does not offer this possibility, the client has the right to use a public transport means (such as a bus) and claim the money from the company. Not so a private transport, so the airplanes would be discarded. Cancellation expenses could also be claimed, such as a hotel night. What if I want to travel to or from Zamora? In Xataka We have contacted Renfe’s customer service. From Facua they point out that if we have a ticket with departure in Madrid to a Galician city and cover the journey to Zamora (or we start it in this city to Madrid) we have the right to receive part of the previously paid ticket. The same has been confirmed to us from the customer service of the railway company but, unlike the change of tickets or its cancellation, it cannot be done by telephone. In this case, you have to perform a online claim by filling out the form which is facilitated on the web or attending the office of the origin or destination station. Little in advance. Until now, Renfe has preferred to hurry until the last moment the cancellation of the trains. To the point that the confirmation that no train would circulate today in the high -speed line has not reached almost noon. That is causing many users to ask the company through social networks like Twitter what will happen to their tickets. The answer is repeated in that case: the client will be informed by social networks, mail and SMS. The telephone service and the website are being referred to change or cancel the tickets but in X only reference is being made to the confirmed cancellations and not to the trains that, it is not confirmed, if they will circulate in the next few days. What if I travel the weekend? In Xataka We have asked Renfe’s customer service if possible change or cancel a ticket for next Friday. They have confirmed that yes, there would be no problem even without the company having not yet confirmed the cancellation. From Facua they explain that in this, and in any other case, there is no minimum anticipation time with which Renfe or any other company must operate. “It remains in the good or bad faith of the company because if you know that it will be impossible to travel, you should inform you as soon as possible so you can look for alternatives and not have to adapt at the last minute.” Despite this, we can confirm that by telephone, these returns are being admitted even though there are still no confirmed cancellations beyond today, August 19.

We have been listening for years that “a glass of wine a day is good for health.” Science is clear that

by

Many times we have heard that “a glass of wine a day is good for our health.” We have also heard that “the Recommended alcohol amount It is zero”Who is right in this debate? The debates about the benefits and prejudices of a food are not exclusive to fermented drinks such as wine or beer. The relationship between eggs and cholesterol is a classic example but we can also find apparent contradictions regarding the consumption of coffeehe rice or the potatoes. Human health has many dimensions and our nutrition is very varied (even the poorest diets involve the consumption of a wide range of compounds present in the ingredients of the product or in their additions). Studying in detail The effect of each product is difficult precisely for this reason. That is why science often advances slowly, with the succession of seemingly contradictory studies that are actually simply refining the aim. However, the accumulation of these experiments is granting us a better idea of what happens in our body when we consume alcohol, even when this consumption is restricted to “a glass or two” wine. To better understand the debate, we can start asking us, what is good for wine? The idea that wine can be beneficial to our health is mainly based on polyphenolsnon -nutritious substances but with antioxidant capacity. These compounds present in grapes of which the wine is fermented, they can be beneficial to our health. The problem here is that There are non -alcoholic alternatives where these compounds are also present, such as must or grape itself. In part due to these compounds, it is usually attributed to wine Potential benefits About our cardiovascular health. Experts believe that this improvement could be due to the fact that these compounds favor the reduction of blood pressure and reduce cholesterol. Still there is some discrepancy in this regard among the different studies. A drink with risks Cancer is One of the main risks that are associated with excessive alcohol consumption. AND There are several types of cancer which have been associated with this consumption: in addition to the liver, alcohol consumption has been linked to oral cavity cancer, pharynx, larynx, esophagus, colorectal and, in the case of women, with breast cancer. “The response to whether the relationship between alcohol consumption and cancer risk is clearly established is that there is sufficient evidence,” said Marina Pollán, director of the National Epidemiology Center, in statements collected by Science Media Center (SMC) Spain. The risk, of course, “is proportional to the amount of alcohol ingested, being lower for moderate consumption.” But beyond cancer, excessive alcohol consumption has been conventionally linked to the appearance of the Hepatic cirrhosis (which can also lead to cancer). This disease It arises with the formation of “scars” in our liver, and can also be caused by hepatitis. While we link moderate consumption of wine to an improvement in heart health, alcohol consumption can have an opposite effect. This has also been related to the appearance of alcoholic myocardiopathy, arrhythmias and other heart problems. It should not forget the relationship between alcohol consumption and mental health problems such as addiction itself, being able to exacerbate existing problems. Various studies made in recent decades They have pointed out Alcohol as psychoactive substance More harmful In social terms. One of the most outlined studies in this field was carried out in the United Kingdom and Posted in 2010. Posted in The Lancetits results indicated that this was not so much to the damage it generated in the individual (in this sense it was overcome by heroin, the crackand methamphetamine), but for its social cost. However, these risks are generally manifested after consumptions that we consider “excessive”, in contrast to “moderate” consumption that is often promoted. The problem is that, beyond social conventions or recommendations perhaps without excessive scientific foundation, we do not know if there is such a thing as moderate consumption. According to the Monograph Alcohol 2021. Consumption and consequencesof the Spanish Observatory of Drugs and Addictions, this border does not exist, or in the words of the text itself: “There is no level of risk consumption free of risk.” That is why the health authorities speak not of “moderate” consumption but “low risk” consumption. The risk is never zerobut it is possible to keep it low. And how much is considered “low”? According to the report limits of low alcohol risk consumption, this would be two standard drink units (UBE) in men and one in the case of women. These “standard” measures are equivalent to 10 g of alcohol or, in terms of wine, approximately a 100 ml glass. It is not the same to ensure that moderate alcohol consumption is compatible with a healthy life than to say that this moderate consumption is beneficial to health. Nor is it the same to say that wine can generate a specific benefit in our well -being with ensuring that this possible benefit can be greater than the risks involved in this or other alcoholic beverages. As we pointed out at the beginning, alcoholic beverages (like any other food) contain a myriad of compounds, some harmful, other beneficial for their operation. The general consensus is that the damages of compounds such as alcohol are superior to the benefits that others such as polyphenols can provide. In short, a glass of wine a day can hardly kill us, but We must be aware of the risks They are associated with her. As always, a balanced diet and an active life can always help us reduce our risk of suffering certain diseases, perhaps even helping us to compensate for these small excesses that we can incur.

The bad thing about Framework Desktop is that it has welded memory. Good too

by

In 2021 the portable panorama was bleak in a key section: The right to repair. Manufacturers made it more difficult to try to solve problems or update these machines. It was then that a small and unknown company He showed us That there was an alternative. That company was called (and is called) Framework. Their Modular laptops have since demonstrated being An absolute reference in repability and expansion capacityand in recent years they have maintained that tradition. A few months ago they advanced the launch of Two new portable modelsbut next to them a surprising machine arrived: a desktop minipc that, curiously, seemed a betrayal to the principles of the company. That machine is none other than the Framework Desktopa different team both for its exterior and its interior. To start, we are talking about a minipc format equipment with a mini -it plaque and a tiny box with a volume of 4.5 liters. That box also has A differentiating design With a front panel in which we can place 21 “tiles” that we can also customize by printing them in 3D ourselves (The designs To do so they are available). The team also presumes from those already famous modular ports in their laptops and that allow to create a tailored inputs and outputs. We can buy them separately and incorporate new modules when we need it. That in regards to the outside. Inside, the technical specifications are as follows: Framework Desktop Processor AMD Ryzen AI Max 385 (8 cores, 16 threads, up to 5.0 GHz, soldier) AMD Ryzen AI Max+ 395 (16 cores, 32 threads, up to 5.1 GHz, soldier) GPU Radeon 8050s Graphics (32 nuclei, 2.8 GHz) Radeon 8060s Graphics (40 cores, 2.9 GHz) NPU Up to 50 tops Memory 32/64/128 GB LPDDR5X-8000 Welded Storage Flexatx 400W Front ports 2 x customizable I/O modules Rear ports 1 x HDMI 2.1 2 x Displayport 2.1 2 x USB-C (USB4) 1 x RJ45 (5GBE) 2 x USB-A (USB 3.2 GEN1) 1 x minijack 3.5 mm Feeding Flexatx 400W Dimensions and weight 96.8 x 205.5 x 226.1mm 3.1 kg 4.5 L mini -it box Price From 1,309 euros In these specifications it surprises how we say we find a configuration in which the AMD soc (with the CPU, the integrated GPU and the NPU) is welded to the motherboard, but it is also the memory. That seems a betrayal to the “replaceable and replaceable” spirit of Framework teams, and is something that has already caused some criticism. A the AI workstation for all audiences Some of the analysis Independents who have evaluated the team criticize him for that. However, that decision has its reason for being: as the company responsible explained in the Official announcement: “To enable the huge 256 GB/s memory bandwidth offered by Ryzen AI Max, the LPDDR5X has welded. We spent months working with AMD to explore ways to solve this, but finally we determine that it was not technically viable to install modular memory with high performance with the 256 -bit memory bus.” It is a reasonable argument, especially considering that although this team has a certain gaming personality, its true focus is another. These teams make use of a unified memory architecture (UMA) That makes no dedicated video memory: the GPU uses RAM as video memory, so 32, 64 or 128 GB of RAM are shared between CPU and GPU. It is an idea similar to the one handled by Apple in its MX chips: there the unified memory allows to be used interchangeably by the CPU or the GPU. And there is the interesting thing about these machines, which are in essence affordable work stations to work with local AI models. We already talked about this week of how GPT-Oss-20b, Openai’s open model was great but showed that having a lot of graphic memory was important for this type of scenarios. Well, Framework Desktop raises a decent alternative to Apple teams and their unified memory. If, for example, we buy the 128 GB model of RAM (2,359 euros), We could dedicate up to 112 GB of those available for video memory. That gives a lot of play to work with heavy models such as the “Large” variant of Openai (GPT-Oss-120b) or, as they explain in Framework, with models as it calls 3.3 70b Q6, for example. In fact, that is where this team really provides value, which also maintains a low profile in terms of power (the consumption peak is 140W) and also in noise. We are not before a gaming team competitor with dedicated graphics: if what you want is to play every pill (even in Minipc format), this may not be the best alternative. But if you want, you are rather occasional gamers and what you are interested in is to have a powerful work team and allow you to experiment with local AI models, We are facing what is probably one of the best current alternatives If you are looking for a compact, efficient and silent team. The other options are clear: a high -end MAC with the maximum amount of unified memory that you can pay, or a PC in which you combine several dedicated graphics (to add their graphic memories) and that therefore will consume a lot of energy, it will be voluminous and predictably make a lot of noise. Could Framework Desktop have been a more modular, reparable and replaceable equipment? Definitely. But that is what are already the majority of current PCs. Here the manufacturer has taken another way, and we believe it is a very interesting approach. Now it will be the users who will decide (you will decide).

Nolan is rolling ‘the Odyssey’ in the Western Sahara. A good part of Spanish cinema has been thrown over

by

In the absence of One year for the premiere and having seen Only an official image From what it holds, the next of Christopher Nolan is already raising some controversy, although this time the reasons are completely extracinematographic. The filming of the film in the city of Dajla, in Morocco, already He aroused certain protests a few weeks ago, and these are now increasing with A statement signed by a large number of Spanish artists They ask for transparency with the reasons to have chosen that place. All against Nolan. Directors such as Rodrigo Sorogoyen, Benito Zambrano, Fernando Colomo and Icíar Bollaín and actors such as Javier BardemJuan Diego Botto, Carolina Yuste, Javier Gutiérrez, Nathalie Poza, Carlos Bardem, Guillermo Toledo, Alberto San Juan, Melanie Olivares or Luis Tosar have joined the aforementioned prior manifesto of the Sahara International Film Festival (Fisahara) against the recording of the film in this area of the African continent. The manifesto asks the producers of the film to “break their silence on why they chose the city of Dajla, occupied by Morocco, in the Western Sahara, as a place of filming of the movie scenes.” Without consent. The manifesto explains the reason for the protest: to film “without the consent of the Saharawi people. The only consent he received came from the occupant force: Morocco.” The problem, according to the festival, is that “Nolan (…) may have contributed without knowing it to the repression of the people of the Western Sahara, helping to normalize the brutal occupation of Morocco.” And he continues: “Morocco has turned Dajla into a tourist center, as Netanyahu intends to do with Gaza, a place to practice kitesurf, cultural events (…), conferences, renewable energy projects used to make the occupation green, etc.” The background of the conflict. The Western Sahara conflict It originates in 1975when Spain left its colonies, delivering the territory to Morocco and Mauritania instead of celebrating the self -determination referendum promised to the Saharawi people. Morocco launched the “Green march“That same 1975, an invasion of 350,000 civilians accompanied by military forces that occupied the Western Sahara, causing the Saharawi population to run massively into the desert and subsequently to the refugee fields of Tinduf, in Algeria. During this escape, Moroccan aviation systematically bombarded civilians refugees with napalm and white phosphorus in Camps like Um-Draigawhere they died between 2,000 and 3,000 Saharawis. 170,000 Saharawis They have lived as refugees for almost 50 yearswhile the Polisario Front continues to claim the independence of the territory and the right to self -determination recognized by the United Nations, in a conflict that resumed militarily in 2020 after 29 years of high fire. A laundering operation. The Moroccan government has been immersed in an intense international image washing strategy in relation to the Western Sahara, focused on the normalization of the occupation, the Economic and tourist promotion of the territoryand diplomatic and media manipulation. That is precisely what is attributed to Nolan from the statement that may be helping to be done, consciously or not. Much discussed lately it has been the Mass Influencers Invitationjournalists trips and content creators of European countries to promote the occupied city of Dajla. Nolan’s key role. Reda Benjelloun, from the Moroccan Cinematographic Center, told the local environment Stockings24 That the production of ‘the Odyssey’ has a vital importance for the city, since it is the first major Hollywood production that does so. In a radically opposite position is the Ministry of Culture of the Polisario Front, the Saharawi nationalist group that seeks self -determination, and which issued a release in which he affirmed that “this act constitutes a dangerous form of cultural normalization with the occupation, and an unusual exploitation of art and cinema to bleach the image of a colonial situation that is still imposed by force” In Xataka | Morocco has given Israel 34,000 km² of the Atlantic for gas exploitation.

The good news is that there is a material that works well on the walls of fusion reactors. The bad: it is lithium

by

We know how the sun works. Another thing is to imitate it. If we got Build a nuclear fusion reactorwe would have clean, safe and practically unlimited energy. But doing so involves incredibly complex engineering challenges. The wall problem. One of the more colossal challenges In nuclear fusion is to build a container that supports a hottest plasma than the sun’s core. For years, scientists have been experiencing with various materials, from graphite to high resistance metals such as tungsten. A recent researchthe result of an international collaboration of nine institutions, confirms that we have a star candidate that works spectacularly well for the wall of the reactors: lithium. A self -refrasinal shield. To understand why lithium is so attractive, you must first visualize the hell that is unleashed inside a tokamak, the most common fusion reactor design. A hydrogen gas, mainly its deuterium and tritium isotopesmore than 100 million degrees Celsius is heated to become a plasma. Magnetic fields potently confine it so that it does not touch anything, but it is impossible to prevent some particles from escaping and violently shocking against the interior walls of the reactor. This is where lithium shines because it can be used in a liquid state. Instead of eroding and degrading with each impact, it flows and heals himself instantly. This self -referential liquid layer would protect the solid components behind. Moreover, if the reactor walls are hot enough, the lithium can form a steam shield that absorbs much of the impact before it reaches the solid surface. Goodbye to graphite? Research shows that lithium is not only a passive shield, but an active plasma conditioner. Instead of reflecting the fuel particles that escape, cooling the edge of plasma and destabilizing it, lithium absorbs them. This helps keep heat where it has to be and, therefore, to stabilize the fusion reaction and improve the confinement of plasma. According to researchers, lithium is a promising candidate to replace graphite, which has a much higher erosion rate. Applied in tungsten walls, it allows to operate the fusion to greater power densities, opening the door to more compact and efficient reactors. Two ways to apply it. The researchers tested, on the one hand, to cover the lithium walls before lighting the plasma and, on the other, to inject lithium powder directly on the plasma during the reactor operation. The injection was much more effective when creating a uniform and stable temperature profile, one of the sacred conditions for commercial fusion. All tests were carried out at the Tokamak Diii-D of General Atomics with financing from the United States Department of Energy. The authors of the study, published in the Materials and Energy nuclear magazine, are researchers of the Princeton plasma physics laboratory and his collaborators. Bad news. In addition to exercising even more pressure on the already tensioning lithium market (Although it does not scarce, it is not extracted to the rhythm that grows its demand), there is a more alarming problem. The lithium is too much Well at work. Catch the tritium with a very high efficiency, preventing it from returning to plasma to be used as fuel. If the tritio is stuck to the walls, the reactor ends up running out of fuel and the cycle breaks. The accumulation of radioactive tritium in cold areas and difficult to access the reactor also greatly complicates its maintenance and is a safety risk. To top it off, the retention is more significant if the lithium is injected with the reactor in operation, the most efficient application method. A possible solution. The key is that these experiments were carried out with lithium in solid state, at temperatures below its melting point. In a real reactor, with liquid lithium, The solution could be a “dialysis” system: Instead of bathing the walls by a lithium river and leaving it there, it would be continuously extracted from the reactor, taken to a processing plant to separate the tritium trapped, and pumped back, clean and ready to continue working. The reactor design would have to adapt to this new proposal. It would be necessary to avoid the cold areas where lithium and tritio could accumulate and stay stagnant, keep the walls at higher and more controlled temperatures, and include the circuit to extract, processes and continuously introduce lithium. A material that solves multiple problems in our mission of simulating the sun, but in return introduces new and also complex.
