China has been building the Great Green Wall for 50 years. What I had not planned was to alter the rains

by

The China’s forests are growing. It has nothing to do with a natural process, but with a meticulously followed strategy to contain the desert expansion and reforest the country with billions of trees. The consequence of this reforestation is not limited to having more trees and two studies have just shown the counterpart of massive ecological engineering. This is not good news: the continental hydrological cycle is being altered. The Green Wall. Of China’s deserts, the Gobi may be the best known, but the Taklamakan It is one of the most problematic. 85% of this 337,600 km² desert are dunes, which at certain times of the year generates sand storms that leave the surrounding towns without crops. And countries like the two Koreas or Japan too they suffered the effects of storms. Furthermore, it was growing, so in 1978, the country launched march the Refugio Tres Norte Forest Program. The strategy: a series of tree belts to contain the expansion of its largest deserts. The objective: to go from forest cover in the country of 5.05% in 1997 to almost 15%, and the idea is complete that belt by 2050 with a total of 4,500 kilometers long. At the moment, the Great Green Wall has completed the shield around Taklamakan with a belt of about 3,000 km, observing a decrease in sandstorms. Consequences in water. Apart from that desert, in others such as Ulanbuh, Korqin, Hunshandake, Maowusu and Kubuqi, tens of thousands of square kilometers of forest and pasture have been built. And, although the storms have decreased, different investigations are noticing a secondary effect: an alteration of the water cycle throughout the continent. Published in Earth’s Future, a study carried out by Chinese researchers shows how new vegetation has increased evapotranspiration in the region. Bottom line: More water is being pumped from the ground into the atmosphere, meaning winds are transporting water to regions like the Tibetan Plateau as rain while the monsoon regions of the northwest and east are suffering a decrease in its net water availability. Non-uniform redistribution. This greater green cover causes restored forests and grasslands to transpire more water than bare soil or traditional crops. This additional moisture It enters the atmosphere, which falls in other regions as rain. According to the study, the consequences at the national level were the following: Evapotranspiration increased by 1.71 mm/year. Precipitation also increased by 1.24 mm/year. Water availability (from aquifers and springs, for example) decreased by 0.46 mm/year. And, as we say, the process is not uniform because the water is moving from one area to another. Greening/conserving water. It is not the only study published on the subject, but it is one that coincides in time with another published in August of this year in which, after analyzing 1,046 hydrological stations and their data from the last 60 years, they discovered that the flow of the rivers decreased by more than 70%. Their conclusion is that it is not an effect of climate change, but of changes in the landscape caused by human intervention. It makes perfect sense: trees need water to grow, and that amount of new trees makes them act like a giant pump, reducing the amount of water that feeds the rivers. Thus, there is a tension between greening China and conserving its water, since once in the clouds, it precipitates air currents wherever you go. Implications. In the end, the researchers conclude that the strategy when managing water must be changed and that hydrographic plans must take into account both the land basins and the “air basin”, anticipating where the water evaporated by the forests will travel. Because the ambitious reforestation plan has 24 years left and the country has invested a lot in it directly – by planting trees – but also with policies that prohibit the felling of forests or with incentives for farmers to convert their croplands into pastures. And, well, the consequences not only have to do with water. That the Natural Forest Protection Program prohibited logging in primary forests provoked that Chinese loggers would ‘loot’ the Burmese forests. Something that adds to the conflict between both nations.

Japan is the only country in the world where the green traffic lights are blue. And the reason is called “aoshingō”

by

Red, amber and green. The three colors of traffic lights around the world. All over the world? No, some particular Japanese traffic lights resist today and forever… the Vienna Convention on Traffic Signs and Signals to which more than 50 States are adhered. Although there are curious absences in it, such as those of the United States or, of course, Japan. This regulatory framework was signed for the first time in 1968promoted by the Economic and Social Council of the United Nations. The text reviewed previous regulations with the aim of homogenizing traffic in as many countries as possible. The last review, in fact, is from 2003 and it addressed the modernization of some signs or the priority rules on roundabouts. The intention is that what we understand in Spain as a Stop is also the same in France or Germany. And so it is, in fact, because all of Europe subscribes to said text. But the most striking absences, such as that of Japan, give rise to curious anecdotes. Like finding traffic lights where the priority of passage is not granted with green, it is applied when the light turns blue. Blue, I love you blue And if you travel to Japan and plan to drive, there is one detail that you should not overlook (beyond the fact that you drive on the left, remember): the green light on some traffic lights is blue. Or turquoise, more accurately. The origin must be found in the language itself. The Japanese did not have a specific word to refer to green. To mention it they referred to the word “Ao”. The problem is that “Ao” It refers to a wide spectrum of colors and among them, as you can imagine, blue or greenish blue or turquoise. Some sources suggest that the word “Midori”, which refers specifically to the color green, became popular during World War II for a purely practical matter when it comes to differentiating both colors. However, a good part of society continued to refer to green as “Ao” and, in fact, it continues to be part of words that are applied exclusively to define green objects, such as aoshingō…which is actually the official word for the green traffic light even though it doesn’t specifically mean green. In 1960, Japan signed its own Traffic Law where this term was collected to talk about the traffic light. This law is, therefore, prior to the aforementioned Vienna Convention and remained intact until 1973 when a ministerial order ended up specifying that the traffic light It had to be as blue as possible within the greenas a compromise measure between maintaining the traffic lights that were already installed and approaching international conventions. The result is that the oldest traffic lights have a more intense blue and the most modern ones have a green tone with slight blue nuances that can remind us of turquoise. However, they are not exactly green because the term “Ao” works, as we said, for both blue and green.

On this island in Japan there is a traffic light that only turns green once a year, and not precisely to control traffic

by

On the small Japanese island of Himakajima there is a traffic light which remains flashing amber or red all year round. Only during one day in May does it change its usual behavior and activate its green light (or blue, as they insist in Japan). This is not a fault. It was designed this way for a reason that goes beyond traffic control. An educational traffic light. The traffic light was installed in 1994 at the Himakajima East Port intersection, but not to regulate traffic. The island barely has 2,000 inhabitants and few vehicles circulate on its roads. The traffic light exists solely to teach children of the place how the urban signals work before they leave the island for larger cities. One less problem. According to explains the Himaka Road Safety Association, which promoted its installation, minors grew up without real experience with traffic lights. Before, they used small models in traffic safety classes, but the children themselves asked “what does a real traffic light look like?” account Kazuo Sugiura, former president of the association, to the local media Asahi. One day a year to learn. Every May, the traffic light is activated for a full day. Third and fifth grade students from the local school go to the crossing accompanied by teachers, parents and authorities. There they practice how to cross correctly: they wait for the color to change, look both ways and cross the zebra crossing with their arm raised, just as they would in any city in Japan. More difficult than expected. The children also discover that calculating the time they have to cross the pass is not as simple as it seems. “It was complicated because it turned red when I was trying to cross,” explained a third-grade student after practicing with her bicycle. The exercise helps them understand the real times of light change and develop security reflexes that they cannot acquire in their daily life on the island. An unexpected tourist curiosity. This little anecdote has gained notoriety beyond Japan. Every year videos and photos circulate on social networks showing the peculiar educational ritual. Some users even consult the local government website to find out the exact date of “green day” and witness the event, although it varies slightly each season. It is already part of the island’s identity. Once the annual training is completed, the traffic light returns to its flashing lights routine. It does not serve any practical function in traffic control, but it has ended up becoming a small symbol of how the community of this island prepares its children for the urban world. The rest of the year, Himakajima remains a quiet place known for its beaches and octopus dishes, with a traffic light that counts down the days until it can turn green again.

There are green, orange and even purple USB ports. The color rule that indicates your generation is extinct

by

There was a time when everything was easier. If the USB port was white, it was slow; if it was black, it was standard; and if it was blue, it was the fastest. That rule that helped us Easily identify USB-A generations It’s gone. The arrival of new standards, charging functions and brand marketing has meant that today we find a wide range of green, orange and purple ports that no longer mean much. Image: StorageReview The original color code. The current chaos, as we explain in our guide to the USB standardit was not planned. The USB-IF organization tried to standardize it: white corresponds to USB 1.x, black for USB 2.0 (480 Mbps), and blue (or turquoise) for fast USB 3.0 (5 Gbps). First confusion. That is a product of the charging ports: the first problem came when colors began to be used to indicate power functions, not just data transmission. This is how the yellow, orange or red ports arrived. These usually indicate an “Always on” or “Sleep & Charge” function, which means that the port continues to provide power even when the computer is turned off or in sleep. More speed, more colors. To differentiate USB 3.1 (10 Gbps) and 3.2 (20 Gbps), the standard suggested the color turquoise blue, or failing that, red. Here the system began to leak. And the final blow came from marketing. A purple USB cable for a Huawei device indicates that it supports SuperCharge, its fast charging technology. Image: Reddit The rule became extinct completely when the brands decided use colors as corporate identity. The most famous case is that of Razer, which dyes its ports a characteristic lime green. Likewise, if you see a purple port, it’s probably from Huawei. The Chinese manufacturer uses them to identify its devices compatible with SuperCharge (its fast charging system), although technically it is still a USB 3.1 port. Chaos also in names. If there is already a mess with the colors, there is also a mess with the names: USB-IF itself has contributed by renaming the standards. USB 3.0 was renamed “USB 3.1 Gen 1” and is now “USB 3.2 Gen 1.” In parallel, USB 3.1 is now “USB 3.2 Gen 2”. This makes it almost impossible for a user to know what they are buying without looking at the fine print, a mess that the Wi-Fi Alliance solved much more elegantly. with standards such as Wi-Fi 5, 6 or the most recent Wi-Fi 7. The real culprit: USB-C. The final nail in the color coding coffin is the USB-C connector. It’s just a reversible connector, but what’s inside is chaos: the same USB-C port can be a slow USB 2.0, a USB 3.2 or a very fast Thunderbolt 4. The only way to differentiate them is to look for the lightning bolt logo that characterized Apple. Or read the device’s spec sheet because color, unfortunately, no longer means anything.

Green tea has always been thought to be good for losing fat. Now we know why

by

Green tea has been known for centuries for its antioxidant properties and medicinal, and modern science has therefore wanted to investigate whether it really has clear effects on metabolic diseases important such as diabetes or obesity. Now, a new study published in Cell wanted to delve deeper into its mechanisms and reveals that green tea significantly improves glucose sensitivity in obese mice. The diet. To reach these conclusions, the research team put mice on a high-fat diet for four weeks to induce obesity. After this time, they divided the animals: one group continued with the high-fat diet and received a standardized green tea extract (500 mg per kg of body weight), while another group received only water. A third control group consumed a normal diet for comparison. The temperature. The key to the study, and what differentiates it from many others, was temperature control. Mice were maintained in a “thermoneutrality” environment at 28°C. This is crucial because the usual laboratory temperature (about 22 °C) means cold stress for the mice, which forces them to spend more energy to stay warm and therefore lose ‘artificial’ weight. This extra energy expenditure can mask the true effects of the substance studied, such as green tea in this case. In this way, by eliminating this factor, scientists were able to “cleanly” observe the real impact of green tea. The result. They confirmed the powerful effect of green tea on weight control and metabolic health. According to a previous study by the same group, obese mice treated with green tea reduced their body weight by up to 30%, a very significant result. In the current research, it was noted that the treatment “effectively prevented body weight gain.” But in addition to the weight, which can be very good, the most interesting thing is undoubtedly the ability of green tea to make the body better manage blood sugar. Obese mice treated with the extract were seen to restore their glucose levels to levels similar to those of healthy mice, as demonstrated by glucose and insulin tolerance tests (GTT and ITT). Although if you look at the fasting values ​​there are also important changes, since the treated mice had lower sugar values ​​than the obese mice that were not treated. Protective effect. One of the most notable findings was the effect protector on muscle mass. Obesity usually causes a reduction in the diameter of muscle fibers (atrophy), but the study revealed that green tea not only prevented this deterioration, but caused a “significant increase in the cross-sectional area of ​​muscle fibers.” This suggests that green tea protects muscle from the harmful effects of obesity. The mechanism. There are several systems to understand why these effects occur in the body: Fat metabolism: treatment increases the expression of key genes involved in lipid uptake in the muscles, and the creation of new mitochondria is also enhanced, which in the end are the ones that will use up the energy. Glucose uptake: sugar uptake was improved by improving the number of insulin receptors in cells as well as the famous transporter GLUT4 which allows the muscles to capture and use this sugar much better by removing it from the bloodstream. Energy production: increasing the enzyme LDH in the body it is related to an increase in energy metabolism that increased in treated mice. It’s not a miracle. Although the results are promising, researcher Rosemari Otton warns that this is not a miracle solution. The dose used in mice would be equivalent to about three cups of green tea a day for a human, but quality is essential. Otton recommends the use of standardized extracts, since the tea bags we have in the supermarket do not always guarantee the quantity or quality of the flavonoids, which in the end are the beneficial compounds.

45,000 tons of green hydrogen per year

by

For decades, the North Sea was synonymous with oil and gas, holding a good part of the European economy and energy supply. Today, in full transition to renewables, that same sea is emerging as the scenario of a change of era: there has not been discovered a hidden reservoir, but the production of 45,000 tons per year of green hydrogen. Is this possible? Some media They have replicated The same narrative of finding a natural hydrogen site in the North Sea, but the reality is very different. An official statement from Totalenergies and Air Liquide They announced two projects of electrolysis in the Netherlands and Belgium that, added, could produce that amount of green hydrogen every year from renewable electricity generated in the Oranjewind marine wind park. In short, there is no hydrogen deposit “under the sea”. What there is is production potential thanks to offshore wind turbines that provide energy to electrolyte capable of dividing water into oxygen and hydrogen. Electrolysis It consists of applying electricity (If it comes from renewable sources, such as wind, we talk about “green” hydrogen) to previously treated water to separate its oxygen and hydrogen molecules. Subsequently, hydrogen is compressed or transported by pipes towards its industrial or energy use. There are many plans in sight. The project mentioned above contemplates an electrolyzer of 250 MW in Zeeland with the capacity to produce up to 30,000 tons per year, it is scheduled for 2029. Also, there is one of “Tolling” with the Elygator electrolyzer in Maasvlakte, with 15,000 tons per year for the Refinery of Antwerp, operational within two years. This scheme means that Totalenergies does not build or opera directly that electrolyzer: yields its renewable electricity to air liquid, which transforms it into hydrogen, and totalenergies pay for that production capacity In addition, others develop in Europe projects like Hope (Hydrogen offshore production for Europe), coordinated by French Lhyfe. This will install a 10 MW electrolyzer off the coast of Belgium and hopes to produce its first four tons per day in 2026, demonstrating the viability of generating hydrogen directly on the high seas. But is there anything in motion? Pilots have been tested for three years Sealhyfea small offshore plant also from Lhyfe. However, making the leap to large -scale production faces several obstacles: High costs: a single electrolyzer such as Zeeland is about 600 million euros of investment. Technical challenges: corrosion, storms and maintenance in marine conditions. Environmental Impact: Offshore wind farms They can affect to marine biodiversity, fishing or provoking bird collisions with turbines. Fragmented regulation: Each northern sea country applies different norms, which delays common projects. A strategic sea. The European Union has marked as a goal to boost renewable hydrogen to decarbonize sectors that are difficult to electrify – such as steel, cement or heavy transport – and reduce dependence on fossil gas. By 2030 wants to have dozens of electrolyte gigawatts installed. In parallel, its offshore renewable energy strategy plans to reach up to 300 GW of marine wind capacity in 2050, Much in the North Sea. Now, the North Sea does not belong to the EU as a whole: it is distributed in exclusive economic zones (ZEE) from different countries, including Netherlands, Belgium, Germany, Denmark, United Kingdom and Norway. That means that each project must first adjust to the country’s regulations in whose Zee is. To overcome this fragmentation and scale the energy transition, Brussels promotes cross -border cooperation initiatives such as the North Seas Energy Cooperationwhich seeks to harmonize rules and interconnect projects between neighboring countries. Goodbye gas and oil. The North Sea was for decades symbol of the European Black Gold and gas dependence. Today it could become a laboratory of the energy transition. The “Treasury” is not hidden in chests under the sea: it is a challenge that requires investment, political cooperation and technological advances. Only if these barriers are exceeded, the figures will cease to be striking holders to become a true energy revolution.

A green elixir distilled by nuns 400 years ago is the best example

by

In the seventeenth century, a apothecary entrusted the French Benedictines of Notre-Dame du Calvaire a secret formula made with sage, rosemary, honey and piperite mint. Four centuries later, the nuns of Bozy-La-Forêt They continue to distill His famous “Emerald Water” as a soothing and energizing lotion. A symbol of how “natural” has always accompanied health care, long before social networks They would make him a trend. The self -care is fashionable. In Spain, eight out of ten people consider that self -care is key to maintaining good health, According to the Association for Health Self -care (ANEFP). And this perception does not remain in theory: it is promoting a market in full expansion. This is the case of the Italian company ABOCA, which has billed more than 50 million euros in Spain with natural health products for common problems such as coughing, reflux or irritations, According to El Confidencial. At the same time, supplement fever and nutricheastics It has been installed in supermarkets, pharmacies and social networks. 75% of Spaniards has consumed Some supplement: from collagen to enriched vitamins or coffees. The difference is that older people trust capsules and anti -aging protocols, while young people seek the same in “functional” snacks or drinks. ANDThe self -care is no longer marginal. The I radiography of self -care in Spain (2025), prepared by ANEFPoffers a clear photograph: 85.3% believe that self -care can improve healthcare. 8 out of 10 see it fundamental to preserve health. Only 1 in 3 associate it directly with disease prevention. 42.5% recognize that lack of knowledge is the main barrier to practice it. The conclusion is evident: there is interest and disposition, but health education is still for a responsible self -care. Natural yes, but regulated. Not everything that is sold as “natural” has the same base. Natural health products act for physical or support mechanisms (for example, create a barrier against acidity), and have European regulation (Regulation 2017/745) which guarantees your safety and efficacy. As the EU regulations rememberevery health product must carry the CE marking, which ensures that it meets safety, health and environmental protection requirements. The key, Experts warnIt is not to confuse natural with harmless: any substance, plant or synthetic, has real effects on the body. But is homeopathy? It should be clarified: natural health products and homeopathy are not the same. The former have European regulation, clinical studies and verifiable mechanisms of action. Instead, homeopathy is based on extreme dilutions without scientific evidence beyond the placebo effect. In Spain, the Spanish Agency for Medicines and Health Products (AEMPS) has registered more than 1,100 homeopathic products. Despite this, citizen trust It collapses: In 2020 only 17.2% of respondents claimed to believe a lot or much in this type of treatment compared to the more than 50% that said otherwise. The business, which came to move dozens of millions, is in decline. And experts They coincide: Confusing “natural” with homeopathy is a mistake that can undermine the credibility of responsible self -care. A cultural change. More than a fashion, self -care reflects a deep cultural change. As we have already written in Xatakaprevention, aesthetics and emotional well -being are mixed in a new culture that promises energy, youth or health control, but also reveals obsessions and social pressures. Social networks have accelerated this phenomenon and have become shop windows, where self -care appears both as part of the daily routine as in the form of viral tendency. Mental health adds another layer: with high levels of stress and anxiety, many resort to self -care as a personal strategy, although 42.5% recognize the lack of knowledge as the main barrier, According to ANEFP. To this are added social inequalities that condition habits, As investigations of the Clinical Medicine Magazine point out. What seemed before an eccentricity – a lotion of nuns or a functional shake – today is part of a new culture of health that combines science, tradition and marketing, and reflects the contemporary aspiration of control not only how much we livebut how we do it. Between tradition and future. From the discreet distillation of Emerald water in a French convent to viral supplements in social networks, self -care has traveled a long way. Today, it represents a solid, regulated and growing market, but also a cultural phenomenon that reflects our obsessions: living more, living better or simply feeling that we have control of our health. What is clear is that self -care is no longer a marginal practice. It is an industry that combines tradition, science and marketing, and that forces us to ask ourselves not only how we want to take care of ourselves, but with what criteria.

We all know that green is to advance traffic lights. Less Japan, defending that green is actually blue

by

A long time ago We count A fascinating story that had the traffic lights and China as protagonists. It turns out that Beijing tried to change the color of these key traffic devices because use red to “stop” It was “anti -communist”. Of colors and traffic lights also goes the following story. In Japan they have no problem with red, but with green. The blue traffic light paradox. In most of the world the traffic signal that invites us to advance is unequivocally green, but in Japan that same light It’s called blue And, in some cases, it even seems bluish in the eyes of those who visit the country. This peculiarity He has baffled to generations of foreigners, but for the Japanese it is a convention as natural as saying that the sky is blue. The explanation is not found in lamp technology or in an arbitrary decision of the road authorities, but in a Cultural and linguistic background that sinks its roots in centuries of history. The linguistic origins of “year”. In ancient Japanese, they only existed Four basic words To designate colors: red, white, black and blue. The term AO served to name a much broader spectrum of shades than we associated with blue today, including what we consider green and cyan. This linguistic heritage lasted until the Heian periodwhen the Midori word to specifically refer to vegetation and the vitality of green color. However, the force of custom kept alive The use of AO In situations where, for other languages, green nuance is evident. Thus, it is not strange that a Japanese speaks of blue apples, mountains or blue vegetables, although in the eyes of anyone they are green. The conflict. When Japan introduced traffic lights in the 1930s, the progress light was described as green, following the global convention. But in 1960, with the entry into force of the Road Traffic Lawthe term AO Shingō, the “blue signal” was officially adopted. The clash with international standards was exacerbated after Vienna Convention of 1968which set the green as the reference color. Japan did not ratify that treaty, and with it the right to continue using its own denomination was reserved. In 1973, to reconcile customary and external demands, the government decided that the lights should be of a green With a bluish enough nuance As if I could continue to be called Ao. The result was a curious balance: greenish appearance traffic lights, but culturally blue. Beyond the signals. The persistence of AO It is not limited to traffic lights. Common expressions such as aoringo to designate the green apple, Aonori for the green algae that is sprinkled on dishes such as the okonomiyaki, or Aoba for the young leaves of the trees, show how blue overlaps green in the Japanese tongue. In addition, AO acquired a symbolic value associated withor new and the immature. To say that a person is AOI means that it is still inexperienced, a metaphor equivalent to that in Spanish or English we express calling someone “green.” This crossing of meanings reveals how the language not only names colors, but also organizes cultural perceptions and associations around them. Convention turned into identity. Today, although Japanese traffic lights are in green practice, they continue being called blue by millions of people who have inherited a particular way of seeing and describing the world. What for a foreigner is a rarity or confusion, for a Japanese is a tradition that does not need justification. If you want, the tongue has been imposedwork visual perceptionand the result is an example of how cultural conventions can challenge international standards and become part of national identity. Thus, Japan’s blue traffic light recalls that the way we name things influences how we understand them, and that even a traffic light can tell a story of centuries of history, language and custom.

This is how coffee and green tea have sneaked into the list of allies

by

Before looking at the mobile, before speaking with anyone, there is an almost sacred gesture: prepare coffee. Beyond frightening sleep, that cup could have an unexpected benefit to your health: protect your liver. An invisible enemy. More and more people live with a diagnosis that usually goes unnoticed for years: the fatty liver. A disease that in Spain affects one in four adults, According to the Spanish Association for the Study of the Liver (AEEH). Can’t it be detected before? The point is that the liver accumulates fat silently. At first it does not hurt, it does not bother and does not warn. Only when it advances already becomes more serious problems such as fibrosis, cirrhosis or liver cancer. The accumulation can should be mainly two causes: Alcoholic liver disease, linked to alcohol consumption, or metabolic hepatic stanosis (EHMET or MASLD), related to obesity, insulin resistance and metabolic alterations. And a key actor in the equation: sugar, especially the fructose added in sodas, pastries or ultraprocess cereals. Unlike glucose, fructose is almost exclusively metabolized in the liver, which triggers fat manufacturing. An unexpected ally. Among the classic recommendations – e -evident simple sugars, trans and alcohol fats – science has begun to look at coffee. According to Dr. Javier Escalada, Endocrinologist and director of the Department of Endocrinology and Nutrition of the University of Navarra Clinic, This has explained it for Hola magazine: “Coffee is not only safe, but its consumption is associated with less risk of progression of liver damage. It can even reduce transaminases and protect against hepatecellular carcinoma.” Different studies, collected by Cleveland Clinicthey also demonstrate that coffee helps reduce inflammation and prevents the accumulation of fat in the liver thanks to its antioxidants. As Dr. Jamile Wakim-Fleming pointed out to the same medium, a process called autophagy is activated, a kind of internal cleaning that eliminates damaged cells and protects the organ against fibrosis. Another type of allied cup. In parallel, green tea is also consolidated as another ally. Its catechins and antioxidants help reduce liver fat, improve the lipid profile and exert an anti -inflammatory effect. The evidence is more solid in green tea than in black or red. Of course, with an important nuance: the benefits are observed in traditional infusion, not in extracts concentrated in capsules, which in high doses can damage the liver. A great population study in the Netherlands, Published by Journal of Hepatologyanalyzed more than 2,400 people and found that those who took three or more coffee cups a day had less liver rigidity – a fibrosis indicator – against those who did not consume it. The effect was also observed in herbal infusions consumers. Although not everything depends on a cup. It should be put in context. Neither coffee nor green tea are a magical potion. They work, but within a healthy lifestyle. Doctors insist that the basis of fatty liver treatment is to change the lifestyle. That means following a Mediterranean diet, exercising, no alcohol or tobacco, dominating well and controlling stress. As the nutritionist Isabel Higuera has detailed To the Spanish magazine: “The diet set is more important than food in isolation. In these patients it is key to consume enough fiber, healthy lean proteins and fats, but always adapted to each person.” Beyond the cup. The fatty liver does not warn, but it is not an inevitable destination either. There is no miraculous remedy, although science suggests that small daily habits can make a difference. Among them, something as simple as coffee or green tea, which not only clear the dream, also seem to protect the liver. A reminder that health begins in gestures as simple as what we eat, drink and repeat every day.

Spain has more green energy than ever but the system does not endure it

by

Spain presumes to be a world leader in renewables. In spring he covered 100% of the demand with clean energy and in July came to beat records in renewable energy with more than 10,000 GWh, According to Electric Red Data. The paradox is still evident when taking a look to the light of the light: The green boom has collided with an invisible wall – with saturated networks and a chronic storage foul – just when heat waves shoot the demand and check the electrical system. The abundance that became a problem. In just five years, Spain has gone from irrelevance to becoming the second European country that has installed more solar capacity, only behind Germany. However, that abundance has ended up becoming a headache. In May, wholesale prices came to zero or even negative for a third of the month, According to Electric Red Data cited by Financial Times. And in July, despite beating a new renewable production record, with 13,850 GWh, the light invoices continued up, As we pointed out in Xataka In full peak of the heat wave. The paradox is clear: at noon there is fun cheap energy, but when the sun falls the network cannot sustain the demand and prices shoot again. The window of the energy transition. The contrast is even more evident if you look at the energy mix. Since July 15, Spain It has not generated electricity weeks From coal for the first time in more than 140 years. A milestone that consolidates the country as a world showcase of energy transition. However, the face B of success is that it is ruining the profitability of the sector. Projects that were just two years ago sold for € 200,000/MW today they barely reach between 28,000 and € 89,000/MW, According to a Financial Times report. The boom has resulted in a wave of “Fire Sales” and a much more uncertain market for investors. The price of running too fast. The renewable expansion has been brilliant, but the infrastructure to sustain it has not accompanied the same rhythm. Since 2020, Spain has allocated $ 0.30 to reinforce its electrical networks for every dollar invested in new solar and wind plants, compared to 0.70 European average, According to Bloombergnef collected by FT. The result is a bottleneck: more than thirty “hot knots” where the network is saturated, especially in Cáceres, Badajoz, Toledo and Ciudad Real. Only in July, more than half of the production cuts –The so -called Curtailments– They corresponded to photovoltaic, with about 392 GWh wasted, According to the Spanish. In addition, the low storage capacity aggravates the painting. When the sun sets, photovoltaic production collapses but the demand remains high, forcing the system to resort to gas to cover the hole. That same gas, more expensive in international markets, has become one of the engines of the price increase. To this was added in January the return of the electric VAT to 21%, after years of fiscal reduction to mitigate the energy crisis, As we have described in Xataka. The result is noted by the consumer: in July, the average price of light reached € 164/MWh, which meant that an average family would pay between 20 and 25 euros more on its monthly bill compared to last summer. Heat has something to say. To structural problems have been added short -term factors. The heat waves of the summer have stressed the system: in June, the electrical demand increased by 14% in Spain, 9% in France and 6% in Germany, As we have explained in Xataka. With the air conditioners operating at full performance, the demand is triggered just when the nuclear and thermal plants reduce their capacity due to the lack of cold water in the rivers to refrigerate. France has been the country most affected by this phenomenon, but Spain has also felt pressure. A decree waiting for the end of summer. The third leg of this whole issue has to do with politics. After the April blackout, the government Approved in June a decree “Antiapagon” which sought to reinforce the network and give an impulse to energy storage. However, on July 22 the norm was rejected in Congress with 183 votes against, in a coalition of rejection between the conservative opposition and part of the left. Since then, the Executive tries to carry out some of these measures through regulatory reforms that do not need parliamentary approval. The other face of the solar boom. Given this panorama, the market looks for exits. One of them are the long -term energy sale contracts (PPAS), which ensure stable prices to corporate customers. The Zelestra project in Belinchón, for example, closed an agreement with pharmacists such as Takeda and Teva when the average of the PPAS in Spain was around € 39/MWh, According to FT. Another change vector is marked by technological giants. Amazon, Meta and Microsoft have announced large data centers in Spain, attracted by the abundance of cheap energy. “There is an enormous interest, they consider Spain the number one fate in Europe,” admitted the CEO of Zelestra in statements collected by expansion. However, enthusiasm ranges with the same obstacles: slow permits and lack of network connection points. It is not exclusive to Spain. As they have detailed in the Spanish report, Germany needs to reinforce 14,000 kilometers of high voltage lines to transfer their renewable energy from north to the industrial south; Scotland has come to pay wind parks for not producing; And in the United States there are about 1,000 GW of renewable projects waiting for a network connection, almost four times the installed capacity. A brilliant future among cracks. Spain has potential, but its electrical system is not prepared to manage so much clean energy. As a summary cited by Financial Times summarized: “The problem is not that Spain has gone too fast with renewables, but has been too slow with networks.” The future of the energy transition will not depend on installing more panels, but on … Read more
