Five ideal portable batteries if you are going to spend all day away from home

by

There are very few weeks left for the return to school, so it is now a good time to buy all the school supplies, but also those devices that can be practical for the next year. If you are going to need a PowerBank or portable battery, in this article we have gathered five models compatible with mobile phones, tablets or laptops. Ugreen Nexode 45w by 49.99 eurosa portable battery aimed at mobile phones. Belkin Boostcharge Pro by 55.89 eurosa PowerBank with a wireless load module compatible with Apple Magsafe. Anker Prime by 79.99 eurosa powerful powerBank that can be used even in laptops. Anker Zolo by 99.99 eurosa portable battery with 25,000 mAh and 165W power. Ugreen Nexode 145W by 125.99 eurosa PowerBank that allows recharging up to four devices at once. Ugreen Nexode 45w If you do not need to carry a PowerBank to recharge the laptop or tablet, it is best to bet on a more economical model that has good capacity. The Ugreen Nexode 45wwhat costs 49.99 euroscomes with 20,000 mAh theoretical and allows to recharge three devices at the same time using its integrated USB-C cable, its USB-C port and its USB-A port. The integrated cable can be used as a transport strap and takes approximately four hours to load. * Some price may have changed from the last review Belkin Boostcharge Pro If you have a mobile with wireless load, but above all a iPhone Compatible with Apple Magsafe, the Belkin Boostcharge Pro has a price of 55.89 euros. It comes with theoretical capacity of 10,000 mAh, includes a pin that works as a support and is quite compact. It also allows three devices to be recharged (two USB-C ports and the wireless load module) and offers a 20W power. * Some price may have changed from the last review Anker Prime The Anker Prime It is the PowerBank that I have myself and works at one thousand wonders. Its price is 79.99 euros And it has a theoretical capacity of 20,000 mAh, offers a total power of 200W and allows three devices to be recharged through its two USB-C ports and its USB-A port. It is compatible with mobiles, tablets and computers. It includes a screen that shows information related to the load status and takes just over an hour to completely load. * Some price may have changed from the last review Anker Zolo A step above we find the Anker Zoloa portable battery that stands out for its thin design. Costs 99.99 euros In Amazon and comes with a theoretical capacity of 25,000 mAh, it offers a total power of 165W and is able to recharge up to four devices at the same time Through its two integrated USB-C cables, its USB-C port and its USB-A port.

There was a day that Volkswagen wanted to have “the Bentley of the town.” It went wrong

by

If something has shown us the history of the car is that it is completely irrational, extremely competitive and very conservative. The electric car is demonstrating it clearly. The number of brands has triggered and China wants to make a foothold on European soil. The reality is that Only Tesla seems to have found the way Correct and China is moving in Europe … but with Combustion engines. That conservatism is not new. Raising a brand from scratch is only possible with a huge economic effortsustained and almost blind for years and years (like Tesla)with the help of state media (as Xiaomi and its association with one of the national Chinese car companies). But it is also almost impossible to change the perception that the client has of you. Winning to the client and ascending on the ranks of the market can take decades. A good example is Hyundai and Kia that have some of the best -selling cars In our country but they had to start earning market share selling cars much cheaper than those of the competition. But rapid movements, those who want to position a brand in a higher segment almost from nowhere or those that seek to compete with premium brands with a model that equals features but also in price is generally a call to failure. There is a good handful of examples and the Volkswagen Phaeton is undoubtedly one of the most representative. History of a failure Luckily for those who like cars and unfortunately from manufacturers, the purchase of a car is irrational. It has an inevitable part of aesthetic taste but also for quality perception, affinity with the brand and construction of an image and a history based on the past. That makes, for example, Renault fails with Vel satisf either Avantime Although they were very good vehicles that tried position yourself above the generalists. Nor has Stellantis (and before PSA) achieved return to DS to your luxury past Despite the multiple attempts. And something similar happened to Volkswagen Phaeton. By order of Ferdinand Piëch, then president of the Volkswagen Group, the Germans wanted to assault the premium market with a Berlina that was called “The Bentley of the People”. The intention was to stick with the Mercedes S, BMW 7 series and, curiously for being part of the group, with the Audi A8. The bet was so strong that the possibility to match (or improve) in equipment and materials to its rivals with a more adjusted price was not even tan. It was directly to resemble all fronts (also in price) and in the executives of Volkswagen they took a tortazo. In fact, the Volkswagen Phaeton Not even was a version of Audi A8. Yes, he shared some aluminum panels with the Berlina of the four hoops, as explained in Km77 In the early 2000s, but for development it departed from a blank sheet and even The Volkswagen Dresde factory was builtknown for their Glass structure and for being the one that, discontinued the Phaeton, covers the complete electrical models of the company. In that assault on the heavens, the Phaeton was sold above 66,000 euros for what the German triad looked from you. A Audi A8 It was sold at that time slightly below 69,000 euros. A BMW 7 series It started from 67,500 euros. He Mercedes S Yes it was significantly more expensive, starting from more than 71,000 euros. In those early years of the new century, all German luxury Berlins shared two things: they all had versions above 120,000 euros. And they all had gigantic engines. And the Volkswagen Phaeton was not going to be less. Its most “small” engine was already a V6 in diesel and gasoline versions. From there, it could only be dreaming. Volkswagen’s bet was also sold with a V8 4.2 gasoline, the famous V10 5.0 TDI and an endless W12 6.0 of gasoline that was sold with 420 and 450 hp versions. The average consumption of the latter was around (with the homologations of that time) 14.5 liters/100 km on average. And of equipment, the Phaeton was not badly served: heating seats, electric with memory and massage, bi-xenon headlights, four-zone heshlyzizer, indoor in the skin topped with wood and the possibility of replacing the rear seats with two sidewalks to improve comfort. Developing the car, therefore, was not going to be easy. At least this is attesting to 1,100 million euros that, according to Autoweekthe Germans invested in their development. From Automotive NewsHowever, they raise the figure to 2,000 million euros. But despite the expensive development and the good of the product, selling the Phaeton was not simple either. To the point that, according to this last medium, the Germans lost 28,101 euros for each unit sold. Keep in mind that the company had made a effort huge in machinery, employees and a new factory (The Dresden crystal plant) To launch a car that would meet the quality of a vehicle of its price range. It is said that Ferdinand Piëch delivered a series of unnegotiable requirements to put the car on the street among which was the ability to maintain the interior temperature at 22ºC circulating in a sustained way at 300 km/h with an exterior temperature of 50ºC. And all despite the car was limited to 250 km/h. Only for overestimating the capabilities of the car and that there was no open door to the client’s disappointment. But the market did not respond despite the fact that Volkswagen reached up to 100 patents during its development. Estimates that aimed at 20,000 units sold a year were impossible to meet. Even as the years passed. Because during the decade and a half that the car was on sale only 84,253 units were sold. Volkswagen’s most optimistic forecasts, collect in DiariomotorThey could exceed 35,000 units sold. And, as exceed, the 50,000 cars sold. Seeing one of those people’s bentley was not as complicated as seeing a true Bentley but of course it … Read more

Depseek has just launched something that will bitter the day and the US chips companies: it is called Depseek-V3.1

by

There was a day when Depseek surprised half the world by demonstrating that you could go far with less. Today returns with V3.1 And a message that does not go unnoticed: the model has prepared for the next Chinese chip batch. We are not talking about an automatic market overturn, but about a concrete bet that points in an awkward direction for Nvidia and company. If that technical tune with the Chinese hardware It translates into performance, conversation about who feeds AI in China is going to sound very different. According to the company’s own noteV3.1 opens a hybrid inference in the purest style GPT-5: the same system with two routes, Think (deep reasoning) and Non-Think (Quick response), Sygons from your website and app. The formulation is clear: “Hybrid Inference: Think & Non-Think, a model, two models.” The company also underlines that the version Think “Reach answers in less time” than your predecessor. That is, not only do pesos change, the inference modes that are already in service also change. The phrase that frames everything: an FP8 “thought for national chips” In a comment set in his latest publication in Wechat, Depseek writes: “EU8M0 FP8 is for the next generation of national chips.” That is the point that tense the rope: it suggests that the company has adjusted the data format, apparently a FP8 which label as EU8M0, to the next wave of Chinese processors. Bloomberg andReuters collect that message And they synthesize it: v3.1 is “personalized to function with next -generation AI chips Chinese. ”In other words, optimization oriented to the local ecosystem. The original comment in Chino (left) and its Spanish translation with Google Translate (right) FP8 is an 8 -bit format that weighs half that FP16/BF16. With native support, it allows more yield per cycle and less memory, provided that the climb is well calibrated. In the official Model Card of Hugging Face It is read that Depseek-V3.1 “has trained using the EU8M0 FP8 scale” format, which indicates that it is not only a packaging of weights, but that training and execution have been expressly adapted to that precision. The delicate part, and it is convenient to be prudent, is that everything points to a chips remittance that will be displayed in the future, since they can take advantage of this scheme natively. So is this bad news for Nvidia? The data of the fiscal year that expired on January 26 indicates that China represented approximately 13% of the company’s revenues led by Jensen Huang. If part of the computation of AI in China Classic duo muta NVIDIA GPU + CUDA ECOSYSTEM To domestic solutions that work with the UE8M0 FP8 format and give good results (presumably chips ascend of Huawei), the demand for Western solutions could be eroded over time. China meant about 13% of Nvidia’s income in the last fiscal year All this happens on the US export controls board: restrictions that sought to stop China’s access to leading chips and that have also accelerated their commitment to self -sufficiency. This year the Trump Administration rehabilitated with conditions the export of H20a chip cut for China. Since then, the state of the H20 has been oscillating: among permits, Chinese regulatory pressures and Nvidia plans to present Blackwell -based alternatives. The background message is that the framework is political and changing, and any route that allows China to depend less on these windows becomes strategic value. You have to remember another fact that helps to calibrate expectations. According to Financial TimesDeepseek tried to train his future R2 model with Huawei chips ascend to official instances and found persistent technical problems. He ended up returning to Nvidia for training, while he was still working on the Compatibility for inference. That episode does not invalidate the current strategy, but puts the bar: to completely migrate its processes is not simple, it requires, among other things, months of engineering. V3.1, therefore, it must be read as iteration. Now the company states that it has prepared its model for the next Chinese chips. Matherena models scores And here we have another interesting fact. Matharenaa platform linked to Zurich Federal Polytechnic School which evaluates models in real and recent mathematical competitions, places GPT-5 as a leader, with 90% in final response tests, already deepseek-v3.1 (Think) something behind although among the best models of the moment. This helps to locate the context: V3.1 Compete above.

Asturias prepares the greatest experiment in Spain to reduce the day

by

When the national debate seemed focused on (still stagnant) Reduction of the working day At 37.5 hours a week, Asturias has decided to step on the accelerator. The Principality government has launched the machinery to launch an experiment on the four -day work week in the region, a movement that resurrects one of the Conversations about the future of work in our country. The first step have already taken it. From the regional government They have already tendered The study that will serve as a road map in this ‘experiment’. The objective they have is clear: analyze the viability and The economic impact to implement a 32 week weekly day in the business fabric of the region. A necessary study to be a success. This study, which will have a value of 16,862 eurosan external consultant will be held. In its content, what is going to be collected will be the similar projects that have been made in other regions, with their failures and their mistakes. In this way, we will not try not to fall into the same stone again as other autonomous communities or other regions of the European Union. In addition, it will also identify the key sectors of the Asturian economy where it would be more feasible to apply this reduction in working hours, and especially where there will really be a benefit of having a four -day day. From there, the assessment of unions, employer and company will be collected to have a complete vision of the consequences that this measure can have. When it will be launched. Once the report has been launched in tender, the manager who manages to get him will have a period of three months to be able to collect all this information, so we can easily leave the next year. When you have all this information, it will be when the Government will propose to companies the possibility of joining this initiative. The main focus will be in the private company. Sources from the Ministry of Science, Industry and Employment They have detailed To El País that the objective will be the private company in this experiment. Although they will also analyze the viability in the public company. But what is clear is that participation will be voluntary, as detailed in the agreement signed between the regional government with the employer and the unions. In these same statementsthe Ministry suggests that this model make Asturias one of the first communities to apply this labor model, aspiring to be one of the greatest experiments in Spain in this area. All this because so far the projects that have come forward have focused on very specific areas of a province or have been a failure, as in the case of the Plan of the Ministry of Industry. The great debate: how will affect salary. Logic can mark that a reduction in the number of hours worked It also carries a reduction in monthly salary. But this is something that at the moment is not clarified in the position by the Principality. As they point out, there is a “varied casuistry” and that, in the absence of a national regulation, it is an “issue to negotiate in each labor relationship.” Precisely, the study that has been in charge will be focused on shedding light on how this problem with companies should be solved. There are a history in Spain. To see similar projects we can go to Valencia in the spring of 2023, where the City Council of the capital tested the four -day week turning on Mondays. The results In this case they were very positive, since an improvement in the well -being of employees was evidenced. Although he also had a negative impact on some businesses by losing this habitual clientele of Mondays. Nationally, the Ministry of Industry launched in 2022 With a budget of 10 million euros in grants A plan to reduce working hours. But it was a disaster, since Only 41 industrial SMEs requested participatingand finally, almost two years later, only five companies were approved, reducing the investment to 500,000 euros. In Spain the regulation will still take to arrive. Although the Council of Ministers I already gave green light To the legislative text that would come true to have a 37.5 hours day in Spain, you still have to wait. His passage through Congress is being torpedored, since for the moment does not have enough support To be published in the BOE. Although the reality is that although it seems A substantial changethere are many companies that collect it in their collective agreements and Other EU countries They have a day below what is raised.

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.

This worker combined three jobs for a year. They threw it out of the three the same day

by

We don’t know if We will run out of work because of AI, But for the moment we do know that There are people carrying the concept of multi -employment to another level. Many share their experience in the Reddit Overemployed community And there has been a case that has caught the attention. A worker tells that he had three simultaneous jobs and, without waiting for him, on the same day he has lost them all. According to the worker, the fault has LinkedIn. What happened. The worker himself tells in This Reddit publication. He is dedicated to sales in the technological sector and during the last year he has been hired in three companies at the same time. The companies were not aware of this situation and thought that the employee was with them exclusively. Everything was going well until one of his bosses tried to look for him on LinkedIn and, not finding him, he began to suspect. LinkedIn’s chivato. The boss who looked for him in LinkedIn did not find him because the employee had been in charge of blocking the whole world of company No. 2 not to discover him. However, he did not count on the boss to contact the hiring agency, which he had not blocked and that he could access the profile where he put that he had another job in company No. 1. Not only did they say goodbye, they also contacted the company No. 1 that, in less than an hour, also fired him. Unemployed. He still had a job, a company in which he had been working for two years. Nor could he keep it. Those responsible for the company Nº2 contacted them and at the end of the same day he had lost all three works. In this case it was not for LinkedIn, but because the worker mentioned the company No. 3 in his curriculum. In its publication, the now unemployed gives congratulations to the Human Resources Department “respect your dedication to ruin my life.” There have been more cases. He is not the only one that combines several jobs in secret. In the same community of Reddit we can find many more cases and in Xataka we have also treated them, such as that of this Barcelona company that He discovered that one of his employees had another job. There are even those that even exceed the protagonist of this article and reach the four jobs at the same time either This engineer who was winning a fortune Thanks to teleworking and chatgpt. Remote work. Obviously, these people do not have full -time face -to -time jobs. At the moment Teleworking is falling capebut the figures are still higher than prepandymia. This has allowed some people to decide to combine several jobs without their employers knowing it. The trick of some workers is do the minimum in each job so as not to have too long days. The role of AI. Many of these multi -employed admit to using AI tools, like this I assured Vice that “AI does 80% of my work” and he only dedicated himself to more complex tasks or refine what AI had done. Others use the Slack messages, write emails or take notes in meetings.

Spotify is no longer a music player. It is a “audio netflix” who wants to devour your whole day

by

After 18 years palmando money, Spotify premiered its age this year with its first profitable exercise in its history. That milestone has been followed by good news as its latest quarterly resultsthat tell their own story. A story that goes far beyond its 696 million users – 276 million of them, Premium. It is that of a silent but beastial metamorphosis. Spotify has ceased to be a music player to become something different. It is a time to capture time. When Daniel EK says that “people arrive at Spotify and stay in Spotify” is subtly describing its strategy: Colonize more and more sound moments of our day to day. A few years ago, Spotify’s natural competitor was Apple Music. And YouTube Music, Deezer, Tidal. Today their rivals are rather Tiktok, YouTube, Netflix, Instagram, and even your own concentration. Compete for your sustained attention. It is not worth being the one who puts background music. The growth in active users – 11% – is, more than more people listening to music, more people delivering fragments of their day to the same platform: Music to go to work. A podcast while you work. Another music while playing sports. An AUDS AUDIOLIBRO. Videoclips with which to kill dead times. Spotify has been weaving A network that catches routines, not a long time. That is the strategy: assault every moment in which we consume audio. And towards that the company goes, towards being much more than a modern Gramola. It wants to be the entity to whom we delegate the decision to hear in each context of our day. The audiobooks looked like a sweetbeard, something tertiary, but The decision to compete with Audible It seems more and more important. The reason: Spotify needs content that works at dead moments that music cannot fill out at all. Long journeys by car. Hours of cleaning at home. Night walks. The audiobooks, such as podcasts, turn Spotify into a company for all occasions, into the audio netflix they promised to be. Spotify detected that there was a silent war for the moments of “partial attention”. While we drive, we cook, clean, we close. Moments when music works, but where an interesting conversation can hook you more. That is why hundreds of millions were spent in Joe Rogan and company. To occupy temporary territories that escaped their control. With the audiobooks gaining weight, Spotify has completed its transformation. It is no longer a music app. Not a music app that has podcasts. Is A total audio platform that coincidentally also reproduces songs, homogenizing everything in that damn word called “content.” They have resigned to be perfect in something to be indispensable in everything. And it is working: almost 700 million people have decided to be in a space that serves as a unique sound universe and does not dispatch towards several specialized applications.

What’s behind the fever for drinking electrolytes every day

by

During a trip to Mexico, the heat passed me an invoice. She was soaked in sweat, exhausted, with dry mouth, despite not stopping drinking water. At that time, a friend offered me a drink with electrolytes. I tried it, without many expectations … but the truth is that something changed. I felt better. It was the first time I tried something like that. Since then, I have asked myself: did you really need those electrolytes or was it pure placebo effect? What are exactly? To understand it easily, electrolytes are minerals such as sodium, potassium, magnesium, calcium or chloride. However, there is a superlative difference that makes it different: they are electrically loaded. In other words, they play a fundamental role in processes such as heart rate regulation, muscles contraction, nerve function and liquid balance in the body, According to Medlineplus. And how do you lose them? They leave with sweat, with urine, and also when you are sick and your body loses liquid quickly. In such cases, replenishing them is not a whim, but a necessity. Dr. Javier Marhuenda, nutrition expert, He has warned at the Spanish Academy of Nutrition and Dietetics in losing too many can have serious consequences: from fatigue and spasms to heart problems or seizures. Should we replenish them daily? The short answer is: not necessarily. And for most people, it is not recommended either. In a report for The New York Times They have pointed out That there is a belief that we need to replace electrolytes constantly, even in moderate training or in everyday life. However, this theory does not have as much scientific support as it seems. “Everyone believes that they need to replenish lost electrolytes immediately,” Dr. Tamara Hew-Boutler, a scientist of sports medicine at Wayne State University, said for the New York environment. It is easier to find them. Actually, a balanced diet already provides the necessary electrolytes. According to nutritionist Heidi Skolnik cited in the same mediumit is not necessary to resort to supplements to obtain electrolytes: everyday foods such as bananas, nuts, legumes or dairy products already provide minerals. Only in specific cases: a dehydration caused by severe diarrhea, high fever, very prolonged exercise sessions or intense exposure to heat, makes sense to use specific drinks with electrolytes. In these scenarios, isotonic drinks can be useful because they usually contain more sodium and potassium than conventional sports options. Optimized water. Social networks have turned “improved” water into a welfare ritual. Electrolyte mixtures, superfoods, adaptogens, natural caffeine and vitamins parade each morning in Stanley vessels and Owala bottles. In an article for glamor They have summarized it In a very ironic way: “The water alone is out of fashion.” Danika Daal, Content creator that shares hydration routines in ASMR, He has commented In the fashion magazine: “The videos about electrolytes have had excellent performance. It is a recent trend and there is still little information available.” In this way, electrolytes have thus added to a broader wave of supplements turned into lifestyle: Collagen milkshakes, Tinuras, vitamin envelopes and “loaded waters” that combine multiple ingredients to achieve functional and tasty well -being. According to Stacie Stephenson, an expert in functional medicine interviewed by glamor: “If the taste helps a person drink more water, welcome. But there is nothing wrong with classical water.” But is there any risk? The electrolyte content in these products is not usually so high as to cause hypernatremia (too sodium) or hyperkalemia (too potassium), although it is important to check tags: some drinks contain Both sugar and a soda. In addition, like most supplements, They are not regulated with the same rigor as medications. Another risk is to drink too much water without replenishing sodium. This imbalance, known as hyponatremiA, it is uncommon but it can be serious, especially in athletes that train for many hours. So, I need them or not? The answer is not black or white. As Marhuenda has summarized: “A person must use these drinks based on their individual needs and their level of activity.” A yoga class is not the same in the park as a triathlon in summer. For those who do intense exercise, they work in the sun or are sick, electrolytes can be useful, even necessary. But for the general population, with a balanced diet and an active lifestyle but not extreme, water – yes, only water – remains enough. Between fashion and physiology. That day in that town in Mexico, the bottle of electrolytes was my relief. Did you really need those minerals or was it the power of salty flavor and autosugestion? Maybe both. The truth is that, beyond marketing, science insists that hydration begins with water. As Dr. Kenefick has detailed to The New York Times: “Many drinks are marketed using electrolytes as a marketing tool.” And while the market bombards us with promises of optimized hydration, the most effective recommendation remains that your mother repeated again and again: drink water.

Generate day energy and hunt asteroids at night

by

At the time they seemed the future of solar energy for their ability to follow the sun with oscillating mirrors. Today the solar concentration plants, which direct the light by heliostats towards a large central tower, They cannot compete with photovoltaic prices collapse. But when a door closes, sometimes a window opens to the universe. Short. A pilot project in the United States has begun to take advantage of these gigantic mirrors when the sun falls for the Planetary Defense. For the day, heliostats generate energy concentrating sunlight in a tower connected to steam turbines. At night, they defend the planet of potentially dangerous asteroids. The figures are devastating. The thermoelectric solar energy has lost the battle against photovoltaic by win. In 2023, the world installed the record figure of 345.5 gigawatts in solar panels, but the solar thermos I barely added 0.3 GW in total. And what is worse, since then construction is not started of no new plant. Although Spain, the world leader in concentration technology, maintains its centrals working, other projects are canceled or reconvisaged. Morocco has replaced the Termosolar part of the MEGACOMPLEJO NOOR MIDELT by photovoltaic after qualifying it as “immature and face technology”. And iconic projects, such as the gigantic Ivanpah plant in Californianow face their closure for not being able to compete with the low price of photovoltaic kilowatt. Save the planet, and incidentally investment. Given this panorama, what can be done with these huge and expensive infrastructure? John Sandusky, scientific researcher at Sandia laboratories, has been turning an idea for almost 20 years. “Heliostat fields do not have a night job. They are simply there, without using,” Explain in a statement. “We have the opportunity to give a night work at a relatively low cost to find objects close to Earth.” The proposal is not to use heliostats to take photos of the sky. Its optical quality is not enough to form crisp images such as a telescope. The genius of the proposal, embodied in a Study of the late 2024 That has already been put into practice, lies in using what these mirrors do best: concentrate light. A lot of light. How it works. The traditional method seeks in the long exposure images the steles that the asteroids leave when moving against the fund of fixed stars. Sandusky’s method is radically different and is based on frequency analysis. Instead of aiming at a fixed point, the plant’s software causes the heliostats (mirrors designed to follow the sun) oscillate, sweeping a small portion of the sky at a constant and repetitive rate. The light of the stars, swept at this constant pace, generates a signal in the tower receiver with a specific and predictable frequency. It is the “tone” base of the sky. If an asteroid crosses that field of vision, moves at a different angular velocity from that of the stars. This makes the light that reflects generates a signal with a slightly different frequency from that of the “tone” base. It is a tiny change, but measurable with current technology. And can be used to detect asteroids due to its speed relative to the stars. From theory to practice. A team has demonstrated its viability using a single heliostat, and is already working to climb the project to a large solar plant to increase sensitivity and to detect smaller and more distant objects. Even tracking satellites and other objects in the cislunar space, to sell the idea to the space force. Sandusky’s idea is a masterful example of lateral thought. Instead of building new and very expensive observatories, it reuses a multimillion -dollar infrastructure that would otherwise be inactive half of the time. A technology that fights to survive in the competitive energy market and that could find a second life, a second job.
