Heat was always the enemy of solar energy. A new study says it will be your best ally

by

For decades, heat has been considered the Achilles heel of solar energy. When the sun squeezes and the temperature rises, the solar panels They begin to lose efficiency. In sunny places, from Madrid to Sydney, the paradox is known: a lot of sun to achieve a lot of energy, but also a lot of heat that plays against. However, where some see problems, a new study has found a possible solution. An unexpected ally. A study by the University of Laughborough, Posted in The Journal of Chemical Physicsturn this logic. Researchers have tried some photoelectrochimic flow cells (PEC), an emerging technology that captures light and stores it. The most striking thing about this research is that the more heat they receive, the faster they store energy. The team has even identified an “optimal point” around 45 ° C, where performance reaches its maximum before stabilizing. More in depth. But to understand the importance of this finding, it should be remembered why heat is a problem in conventional photovoltaic panels. The increase in temperature causes an increase in internal electrical resistance. This means that electrons lose energy in the form of heat instead of contributing to electric current, which reduces voltage and efficiency. As we have explained in Xatakafor each additional degree above 25 ºC, the plates lose between 0.05 % and 0.34 % yield, which can translate into falls from 10 to 25 % in very hot days. Instead, PEC cells behave totally the other way around: heat energizes liquid electrolyte, accelerating the ion movement. In this way, internal conductivity is improved and reduces losses, achieving a faster and more efficient load. The benefit of heat. The project led by the University of Laughborough by not needing active refrigeration systems, installation and maintenance costs are reduced. For their part, the most benefited regions would be those with abundant sun and high temperatures. As Dr. Bae has highlighted in Interesting Engineering: “This revolutionizes popular belief and gives us a new way of designing solar storage systems that prosper in heat conditions.” Other ways. Beyond the PEC cells, there are also initiatives that seek to take advantage of heat in solar energy. The Australian startup Coolsheet has designed a passive water cooling system that is installed in the rear of the solar panels. This reduces the temperature of the plate and, at the same time, water is heated that can be used in industrial or domestic processes. As we have explained in Xatakaevery 10 ºC less on the plate can translate into an increase of 4 % in electrical efficiency. From enemy to ally. Solar energy crosses an intense innovation phase. From technologies such as PECs, which make heat into an ally, to hybrid solutions such as Coolsheet, which reuse leftover heat, the future seems to get away from the traditional vision that heat is a problem to fight. What is clear is that, As the University of Laughborough concludeswe are one step closer to a scenario in which the sun not only generates electricity, but also enhance the efficiency and reliability of our energy systems.

A new study associates late breakfast with lower life expectancy

by

One of the Great statements that has always been done in the field of nutrition is that breakfast is one of the most important meals of the day. Given that premise, we are at a time where The ‘what’ we eat has monopolized our attention counting calories, Analyzing macronutrients and discussing superfoods. However, a new research wave is focusing on an equally crucial question: the “when” we eat. Longevity. One of the great objectives that people have is to last how long the better. But, They tell Putin and Xi Jinping with organ transplantation. But although this is not a viable option, a study that followed almost 3,000 older adults in the United Kingdom for more than three decades is clear that breakfast can be key to calculating our risk of mortality. The key point is the time to have breakfast, which would be a great health marker that points to the much (or little) that can be lived. An internal clock. The field of study that focuses on this aspect of our life is Chrononutritiona discipline that studies our internal clock, what we know as circadian rhythmswhich only dictate when we sleep or wake up, but also regulate our hormones, our metabolism and how we process food. In this way, eating in tune with this internal clock seems to be beneficial, according to researchers, while doing it could disagree our internal machinery. The new studyled by researchers from institutions such as the University of Manchester and Harvard, entered fully into this concept, analyzing how food schedules change as we age and what that means for our health. The late breakfast problem. The researchers analyzed the data of 2,945 adults older than 1983 until 2017. The results in this case were quite clear: as the participants aged, they tended to delay the time of breakfast and dinner, and to shorten their daily “food window”. But what caught the care really was the relationship with the health problems that arise with longevity. Greater mortality. Delaying breakfast associated with a higher risk of mortality in the short term. Specifically, every hour of Breakfast delay It was linked to an 8% increase in the chances of dying, even after adjusting factors such as socioeconomic level or lifestyle. New diseases. In addition to increasing the probability of dying, having breakfast in a late way can be related to a greater burden of physical and psychological diseases, such as fatigue, depression, anxiety and multimorbility, that is, the suffering of several diseases simultaneously. Lower survival. A criterion that can agglutinate the two previous values ​​is the survival of a person. In this case, the analysis identified two groups of patients: on the one hand, those who ate very early and on the other, those who ate later. The researchers could see in these cases that the 10 -year survival rate was remarkably lower in the group that ate later (86.7%), compared to the group that made it earlier (89.5%). The effect of aging. Far from being a simple choice of lifestyle, the study suggests that this change in schedules can be a deeper reflection of healthy health processes. Researchers suggest that genetics play a fundamental role in this case. On the one hand, there is a person who have a genetic predisposition to be ‘nocturnal’ which is what is known as a evening chronotype They have to delay the hours of all their meals. On the other, and perhaps more importantly, the study states that the beginning of a disease can be what leads us to change our schedules, and not vice versa. A conditions such as depression, chronic fatigue or oral health problems can alter appetite and daily routines, causing the first meal of the day to postpone. This phenomenon could be related to what is known as “anorexia of aging”, a geriatric syndrome characterized by the loss of appetite and a lower food intake. A health biomarker. The authors conclude that, rather than being a direct cause of mortality, breakfast time could function as a “simple health marker in older adults.” It is an easy indicator to observe for anyone and that can alert on underlying changes in the physical and mental well -being of a person. This research reinforces the idea that maintaining regular food schedules with our day and night cycle is important to have healthy aging. As they explain from the Harvard School of Public Health, aligning meals with the circadian clock can help regulate metabolism and reduce chronic diseases.

Until recently the young people looked at their selectivity note to know what they could study. Now look at something else: idealistic

by

“They ask you to get a good note to enter the race. You do it, but you can’t afford to live in the city where the university is.” Reflection He is from Carlos, a 21 -year -old university student who studies law and fights with the complicated task of looking for a rental that does not swallow his entire budget of the month, something that is not easy in a residential market of Shot pricesconditions Draconians and marked by The “boom” of tourist rentals. His is an isolated case. On the contrary, it reflects an increasingly worrying reality: the price of housing is costing Spain for more than families savings capacityhe is also spending his talent. “It affects the right to study”. That the price of housing influences the place where one can study their career is nothing new. It happened years ago. And decades. Even before the brick bubble. However, as rentals climb up to approach to the bubble peaks of 2007 and Spain entered a “Social Emergency” Marked by the house, the problem has become more and more serious. Have a roof today comes out and force tenants to assume conditions Hardwhich directly conditions students. It I recognized In 2024 the Minister of Science, Innovation and Universities, Diana Morantwhose department even signed A protocol with the Ministries of Economy and Housing precisely to promote “affordable” rental among university students. “The housing crisis is affecting the right to study a university career, Morant insisted. “Access to the university should only be limited by merit and personal effort, not for economic reasons.” “It’s a palmaria reality”. Morant is not the only one aware of the problem. The difficulties that young people find themselves when looking for accommodation worries to unions and even rectors, which They are not alien how the scale €/m2 of cities influences both or more in the future of students than selectivity. “The lack of accommodation is a Palmaria reality. We have 2,000 requests from place in residences for 1,000 squares,” I confessed recently to The country Ángel Arias, rector of the Carlos III University, who laments how difficult it is to solve the problem for the campus themselves. “Building a building is 25 million euros if you have the ground. It is 10% of the entire university budget.” Beyond Madrid and Barcelona. The problem is not exclusive to the great metropolis. “The issue of rates is not a great inconvenience to study at the university. What begins to be the limiting element? In some cities it is already the price of rental houses,” ditch Julián Garde, from the University of Castilla-La Mancha. Similarly, his Extremadura counterpart, Pedro Fernández, is expressed, convinced that the cost of registration no longer removes the dream of the students of the students. They do the rentals, the €/m2. “In Mérida and Cáceres there is a lot of accommodation availability that is used for tourism, and that makes the prices for the students have a lot.” How serious is the problem? Recently Live4lifea student specialized rental platform, launched A study which reveals that when deciding in which university 45% of young people are going to be formed are conditioned by a key factor: the rental price. Moreover, 58% rules out the most expensive cities and 64% indicate the cost of housing as its main obstacle, which conditions both their academic future and their way of looking for floors. “Young people delay as much as possible the search for a place to live during the university course. There are few offers and prices are rising, so they expect much more to see if they find any bargain,” assures The firm’s CEO, Alberto Añaños. The problem is aggravated if you take into account that more and more students They demand training outside their province of origin: in the 2022/2023 course they already exceeded 300,000 people, and many move to another autonomous community. Who do they do? Above all Students with parents with higher studies and good jobs, which suggests a social gap. “You have to pass some ‘hunger games’”. So far the perspective of politicians, rectors and researchers, but … how do the students themselves live? Eldiario.es published A report with testimonies of several university students who demonstrate how the high cost of the house (and the hardening of the requirements requested by the homemade) is conditioning their training. “There are people who are renouncing their university square for the impossibility of being able to pay a rental. If it is already difficult to access a place in the university, now the housing crisis adds one more lock,” Underline Coral Latorre, directive of the Student Union, before warning that this handicap does not affect everyone equally. It weighs mostly in the humblest homes. Idealist slopes. “My sister is 18 years old and has made selectivity. He wants confesses María Ángeles Guzmán, of the Coordinator of Representatives of Public University Students. Another young university student, Avril, 22, sees with impotence how the start date of his face -to -face master’s degree is approaching and does not yet have an apartment in which to stay. He had signed one and even paid to reserve it, but assures that the real estate company told her and her partner that the agreement could not be closed because they do not meet the conditions of “economic solvency study.” Is the house so expensive? The figures are eloquent again. According to Idealista, throughout the last decade (August 2015 to the same month of 2025), rentals have almost doubled in Spain: € 7.5/m2 have passed to 14.5. And that is the state average. In Madrid it went from € 11.9/m2 to 22.2 and in Barcelona from 12.3 to 23.1. They are relevant data because, in addition to being the largest cities in the country, they are also the ones that brings together greater concentration of universities.

A massive study links it with a higher risk of chronic pain in adult

by

During generations, the message has been the same: menstrual pain is normal, a “girls” to endure. But the reality is that a pain of great draft never It is something that should have been normalized. Now, a Longitudinal study Published in The Lancet Regional Health – Europe comes to disassemble this myth and to give an alarm voice: Have painful periods In adolescence it is linked to health problems in the future. A public health problem. The methodology of this study has been based on the monitoring of more than a thousand participants in the United Kingdom for decades. In this way, not only has it been confirmed, it has been concluded that the more severe the menstrual pain at age 15, the greater the probability of developing chronic pain a decade later, at 26. In this way, menstrual pain goes from being normalized to a serious public health problem. A methodology with long -term views. To get to this conclusion, the researchers They used data of the Longitudinal Avon Study of Parents and Children (ALSPAC), An ambitious project that has followed the lives of thousands of people since birth in the 90s. They analyzed the information of 1,157 participants, evaluating the severity of their menstrual pain at 15 years classified as null, mild, moderate or severe. Subsequently, once these participants were already 26 years old, an analysis of their health status was carried out by asking if They suffered some kind of chronic pain. Something that was defined as a pain that lasted at least three months. Worrying figures. After adjusting the data to rule out the influence of other factors such as BMIthe socioeconomic level or previous mental health problems, the results were clear. The first of all, is that adolescents with moderate dysmenorrhea, that is, with strong enough pain to not be able to ignore it, they had an extra 65% probability of suffering chronic pain in the adult stage compared to those without menstrual pain. In the case of the most severe dysmenorrhea, which prevent normal activities, the risk is triggered up to 76% of suffering chronic pain in the future. These data translate into an increase in absolute risk of 12.7 and 16.2 percentage points, respectively. It is a difference too big to be ignored. The study also revealed how common this problem is: almost 60% of adolescents in the sample reported moderate to severe menstrual pain. A problem that extends through the body. One of the most interesting findings in the study is that the association is not limited to the classic abdominal or lumbar pain, which could be considered an extension menstrual pain. What happens in this case is that adolescents with severe dysmenorrhea show a greater risk of chronic head pain, back, knees, dolls, hips and thighs. Because? The authors of the study suggest that behind all this is a central sensitivity. To understand it, we must bear in mind that in adolescence there is a great neuroplasticity, where the nervous system is especially moldable. The repeated experience of intense and poorly managed pain, such as dysmenorrhea, can “train” the nervous system so that it becomes hypersensitive. In essence, the brain and spinal cord learns to be in a constant alert state, which increases vulnerability to develop other types of pain in the future, even in those areas that are not at all related. For Dr. Rachel Reid-McCann, principal researcher, “It is possible that the experience of moderate or severe menstrual pain can alter the structure of the brain and how it works in response to painful stimuli, making chronic pain more likely in the future.”. It is not a purely psychological. In the study itself, researchers have seen a relationship between dysmenorrhea and a subsequent increased symptoms related to anxiety and depression. But these factors only explained a small part of the connection with chronic pain and this reinforces the idea that the main cause is a physiological mechanism, and not simply that “pain is in the head.” You have to stop normalizing pain. The conclusion of the study is a call to action for father, educators and, above all, for the health system. Normalize menstrual pain and dispatch it as “is normal” has great long -term consequences. And that will go to the health system. The researchers point out that menstrual stigma and the lack of education on menstrual health cause many young people not to seek help, or that when they do, their complaints are minimized. In this way, it is believed that early identification and good control of dysmenorrhea can be key to improving the immediate well -being of adolescents and preventing the appearance of serious health problems in the future.

His mega -study for trucks is the largest in the world

by

Huawei has presented the first 100 MW recharge station. The space is designed for the recharge of large -tonnage electric trucks and has put a new roof if we talk about power available in the loaders. It is just another example of how the company is becoming a reference in the market for electric mobility in the country. The biggest in the world. There is only one electric vehicle recharge station with 100 MW. It is in China, of course, and Huawei has raised it. The technology company has opened in Beichuan Qiang, a county in the center of the country, the largest load station in the world for available power, according to Carnewschina. The space is designed for electric truck recharge and its location makes all the meaning, far from the big cities. The most important city in the area is Chongqing that has more than 30 million inhabitants but is 400 kilometers away. This gives an idea of ​​the existing complications to join the large Chinese cities through the use of electric vehicles. In data. As for pure and hard data, Huawei station It is summarized in the following: 18 load points with 1.44 MW powers 108 load points at 600 kW A total capacity of 100 MW of power Two storage spaces of 215 kWh It is estimated that they can recharge up to 700 trucks daily Understanding it. To have a clearer what all these numbers mean, the first thing we have to take into account is that In Spainmost of the rapid recharge points are 150 kW. The most advanced are delivering between 350 and 400 kW but are exceptional. Besides, There are barely cars that can recharge more than 250 kW at the moment. Powers such as those commented above are only available for trucks since a battery is needed that is able to assimilate that power. Byd, in China, has 1 MW chargers that can be used for private vehicles but already explained that the true target audience is heavy transport. With a 1 MW load point, a byd car can recharge 400 kilometers in five minutes. In Carnewschina They point out that at that time a truck recovers about 100 kilometers. It is not a problem since it is assumed that in heavy transport longer stops are expected to rest. A reef. With this type of recharges, Huawei shows that he has found a huge business road. Although byd loaders have been the ones who have caused the most expectation, China technology is another of the big companies than He is developing his own loaders And you can look at you from you. In the case of this new loading station, Huawei presumes the integration of photovoltaic energy, which allows it to reduce its environmental impact but, above all, function disconnected from the main network which allows it to mitigate the pressure on it. It ensures a microred in which the type of energy consumed is balancing and renewable is prioritized. And a reference. The company has risen as one of the market references. In addition to these huge load stations and their 1.5 MW power plugs, it also has a good network of 600 kW loaders for passenger vehicles that, as we have seen, are more than enough for current vehicles. The competitive advantage over the rivals is that Huawei presumes having worked on the liquid cooling of the charger so as not to overheat the system and, therefore, that the loading power is reduced. The company assured in the late 2024 that it has already deployed 50,000 of these plugs around the country, distributed throughout 200 cities. And it is not the only open front that the company has in the electric car. Right now, it is offering its technology to sustain infotainment systems or software management in firms as powerful in China as Maextrowith whom you have for sale A luxury sedan of almost five and a half meters long Photo | Huawei In Xataka | While European manufacturers think about what the car of the future will be like, Huawei is already thinking about the post-coche era

How to create a podcast from a text to study, investigate or simply listen if you don’t feel like reading

by

Let’s explain How to create an audio from text wearing artificial intelligenceso that you can have a kind of podcast to study or review something when you do not feel like reading. Thus, instead of having to be reading a text, you can simply relax while listening. We are going to start the article with a series of previous tips and recommendations to take into account before putting the task. Then, we will tell you how you can do it with one of the best tools available for it, and we will continue with two ways to do it with assistants of AI as Chatgpt And some other alternative that is also interesting for Generate voice with artificial intelligence. Before starting, things to take into account Before starting to get to work with this, there are some things that you must take into account. First, you must define whether this audio or “podcast” that you want to create is educational, informative or only entertainment. Try too Be clear if you are going to listen to only you or also some other person, in order to polish how well finished it is. A written text does not always sound natural when you listen to it, especially when you have longer and somewhat intricate phrases. That is why it can be recommended that The phrases are short and close languagenot something that makes you heavy listening. In cases where you are going to be able to do it, Decide tone and voice stylechoosing between one more formal or informal. This may depend on the content you want to consume in audio, and also if you are going to listen to only you or other people. It is also recommended that You take care of the audio duration. The recommended duration may vary, because if it is something dense or to study it may be that from 20 minutes begin to get tired, but if it is for leisure or something narrative you should not have problems with longer durations. If it is something dense, try to segment the content well. And finally, Always check the result and do not be afraid to try again If you don’t convince you. Because sometimes the voices of AI may sound unnatural or there may be errors, and that is why it is important to check it even if it is a bit. In the end, The most important part is in the script That you will create to be narrated, and in this it is what you will have to spend most of the effort. Try to be natural, with good scores and well structured. Audios from your notes with notebooklm The first tool you can use is Notebooklm from Google, a service with which you can use artificial intelligence to organize your sources, and even Create an audio summary As if it were a podcast. It is a kind of chatgpt, but in which everything you do will be based on the sources you have added by hand. You can use notebooklm Through its official website or by mobile applications. The official website is Notebooklm.google.comor also in their apps In Google Play For Android and In the App Store For the iPhone. You can use it for free, but its payment version will give you more audio summaries. The first thing you should do with this tool is to create a notebook or work space. Inside, In the left column you can add sourceswhich are the files that the AI ​​will use to obtain the information. They can be text documents, slides, PDF, YouTube videos or links to web pages or online items. Once you have added the sources, Go to the section of Studiowhere the tool will create an audio summary of the content of all files. With this you will create your personal podcast To get information about everything you want. How can you do it with chatgpt and others AI Another option is to use a generative AI such as Chatgpt, COPILOT, Gemini either Deepseek. These tools They do not allow you to create a downloadable audio file although this is something you can do with other third -party tools. What you can do is listen directly to the AI ​​app. What you have to do is Create a summary script of an article. Then, this script can be heard directly in Chatgpt, Gemini or other platform, or take it to another AI that generates a downloadable audio. Let’s explain everything step by step. To start, you have to tell Chat GPT to make you summarize an article or a web page. For that, You must attach it and include the prompt or the instructions to generate your script. The article from which you want the summary can be included by uploading the text file or PDF, or directly putting the website. The prompt that we have used is as follows: “I want to create an audio to listen to a summary of the content of this website. I want you to generate the script to then copy and paste it into a program that passes from text to audio. The script has to be narrative, without structure, you simply have to write it to read it from there. (Link)” As you can see, in the prompt we have reiterated that the text generated by chatgpt It must be natural and should be read directlybecause sometimes if you do not mention it, you can tend to generate a script scheme with things to be filled, and what I want is to generate a text to copy and paste. Here, It is you who decides how and what do you want to make the summarybeing able to be one or several files that you raise or add. Just remember that Everything you upload or vintages will be saved on servers of the company that owns the AI, so be careful in the event that you are adding sensitive data that you … Read more

A study has investigated how many microplastics we inhale daily when breathing. And has an unpleasant surprise

by

From a time to this part, microplastics seem to have sneaked into all areas of our life: From the lettuce that we eat In the salad, even In men’s testicles. This polymer is not only found in the earth where vegetables are grown, in the oceans where the fish are or in The springs where the water we drink comes out. And the idea that all these particles are in the environment that we breathe more and more consolidates. Already in the past ‘Nature’ magazine He published the first evidences that showed that microplastics are found in the air that surrounds us. But now A recent French study Published in the magazine ‘Plos One’ gives us more details about the concentration of these polymers that we are constantly breathing, and how the car is one of the biggest foci we face. The good news is that this gives rise to solutions to reduce your presence. The conclusion of this new study are very direct, but also alarming: we are inhaling a drastically greater microplastics than we believed. The previous estimates have fallen short, very short. The new figure suggests that an average adult inhales about 68,000 microplastic particles every day. One hundred times more than what was calculated so far for the range of more dangerous particles. An invisible enemy that attacks our lungs The problem of measurements that were done so far was a matter of view. The most common methods in this type of detection, such as infrared spectroscopy, are effective to detect particles up to 20 micrometers. However, they are completely ‘blind’ with the smallest particles, which are known as PM_10 (less than 10 micrometers), and that are the ones that can make the lungs the most damage when the different defense mechanisms that the body has. This new study, led by French researcher Nadiia Yakovenko, has used a much more precise technique called Raman spectroscopy, capable of ‘see’ particles of up to a micrometer, eliminating the limitation that the conventional spectrometer had. In this way, we have a new molecular zoom that has revealed that the situation of our environment is much more alarming than was thought. Taking advantage of this new technique, the investigation was conducted in the path of knowing the place where there is a greater concentration of microplastics. In the case of an apartment, the average measure measured was 528 particles per cubic meter. But the problem was when measuring in the car, where the figure shot up to 2,238 particles per cubic meter. Box chart showing the concentration analyzed with microplastics in cars and apartments. Seven apartments and five cars were analyzed. In this way, the simple fact of this in the car makes us exposed to a concentration of microplastics four times higher than that we expose ourselves in our own home. And this is not due to anything other than the amount of synthetic material that we have in a car, such as plastic splashing, carpets or upholstery. All this, added to a very small space and that can be without ventilating for many hours, makes it the ideal breeding ground for the cabin to be filled with microplastics that we breathe at the time of starting to drive. Because the reality is that we do not ventilate the cabin before driving, but that we enter the car, we start and go. The new and alarming daily account: 68,000 particles Here comes the data that changes everything. When combining its findings with those of the history of the bibliography, the team has recalculated the exposure we face on average. In total there are 68,000 particles small size (less than 10 micrometers) to which an adult is faced daily. These are the most worrying particles, since being so small They can reach the alveoli and cross the alveolocapilar barrier formed by pneumocytes and blood capillaries. This means that they can end in our blood. In a lower exposure range are the particles with a larger size ranging from 10 to 300 micrometers. These being larger do not reach the alveolocapillary barrier, but are ‘trapped’ in the mucous membranes of the upper respiratory tract, although they are not harmless, since they crawl to the throat and end up in our stomach. It has important health consequences. This constant exposure to plastic fragments It is not harmless. The authors of the study remember that the inhalation of these particles can be associated with damage to lung tissue, inflammation, increased oxidative stress and also to the appearance of chronic diseases such as COPD. But microplastics do not ‘travel’ lonely. They can transport with them different heavy or polluting metals that adhere to their surface and that once within the body can be released and alter endocrine functions such as endocrine disruptors or increase the risk of other diseases. In this way, this new study demonstrates that there is still much to investigate microplastics and redipline as a complex a public health problem that occurs silently and ‘invisible’.
