3,599 books of all kinds that you can now consult

by

If you are proud of your reading speed, turn side to side: earlier this year, Dan Pelzer died with 92 years, leaving behind A manuscript list of books which had read since 1962. An enormous amount of readings that has generated an unusual interest among fans, since it raises a great diversity of issues on habits and reading records. 3,599 books. That is the amount of volume published in a document that has enabled the searchso you can locate your favorites there. Your goal to read such a amount: try to read a hundred daily pages. Pelzer began to maintain the list when he was destined in Nepal as a volunteer of the peace body, and kept it until 2023, when he had no choice but to leave the reading and after many years as a retiree. Tars. Many of these books betray an indisputable interest in Christianityreligion that Pelzer practiced, according to his relatives, devoutly. There is also abundance of history books, which led him to read no less than ‘History of Civilization’ of Will and Ariel Durant, a huge work in twelve volumes, which if we attend to the registration dates, he took from the library apparently disorderly. However, Pelzer did not disgust authors of Best Self Like Stephen King, Ken Follett or John Grisham. Why the list is interesting. Comments on articles like thisthat they break down the story of Pelzer, demonstrate to what extent in digital times this type of feats touch a fiber. Pelzer’s commitment to reading has its abundant critics (one states that “only about 15% of books are critical of the status quo or show the world from a non -homogeneous perspective. The guy read more than 3,500 books, but only to confirm their own beliefs “), but That vision has all the meaning of the world: His own son described the list in an interview as “a microcosm of his life.” The importance of libraries. It is logical that Columbus Metropolitan Library will take the work of digitizing and visible the list as a tribute to one of its most voracious visitors. For many readersthis list actually hides a real tribute to public libraries as essential tools for democratization of access to knowledge. A 2022 PEW survey He talked about the Americans to read on average 14 books in the year, much less than Pelzer’s 60 annuals. And in a moderate income man, the library plays an essential role. To read all. If you want to undertake the task of imitating the huge amount of Pelzer readings, remember that we have A list of tips to read 200 books a year. The methodology is simple: find a space of daily tranquility and click on it. Always carry a book on. Leave what you have to leave, do not become a torture. And yes, of course, turn off the mobile. Pelzer’s milestone is within your reach. In Xataka | More and more people use chatgpt to read books for them. Has advantages and enormous inconvenience

In 1995, NASA began to drug spiders with amphetamines, marijuana and the most devastating: caffeine

by

We carry decades experimenting with animals. Despite the Ethical issueand that we see more and more vegan products that imply that there has been no experimentation in animals, until Large technological ones resort to this method. And in 1995, NASA made one of the more curious experiments To measure the drug toxicity. And they did it drugs. Measuring toxicity. It is not that someone woke up one day and wondered what would happen if we die LSD to spiders. Or well, exactly that is what happened, but for a good reason and not for fun. In 1948, the researcher Peter N. Witt He wanted to help his colleague HM Peters, a zoologist who wanted to modify the schedule in which his laboratory spiders began to weave the nets. To do this, he administered substances such as LSD, Mescalina (hallucinogen), amphetamines, caffeine and strychnine (stimulating such as cocaine) To the arthropods and discovered something: the schedule did not change the least, but the patterns of the cobwebs. Depending on the drug Administered, the pattern changed, and that revelation served as an economic model to prove the neurological impact of drugs and toxic on living systems. Why spiders? The problem is that the nervous system of arthropods is different from ours, so it is useless to draw conclusions when we want to try effects on humans, but it is interesting to know how these psychoactive substances influence their organism. In 1995, NASA, inspired by Witt’s experiment, chose spiders for new research, but also did it for An ethical issue. They wanted to measure the toxic effect of different compounds, but without resorting to mammals or “higher organisms.” They needed a sensitive and reliable organism, but not controversial. In addition, spiders are perfect because their cobwebs follow fixed and instinctive patterns that, as Witt already demonstrated, was extremely sensitive to chemical alterations. The experiment. Baptized as “Using Spider-Web Patterns to Determine Toxicity“, he experiment It consisted of exposing different European garden spiders to different drugs. To do this, they dissolved a certain amount of drugs in sugary water and administered it directly to the spider through the mouth or by means of flies previously fed with the solution. Once administered, they let each spider weave their air and, later, photographed the web that had been fabric, comparing that creation with cobwebs photographs that those same spiders had made before applying the drug. If you get drugs, don’t tile. The results They speak for themselves: In addition, the methodology was stricter than the one carried out by Witt half a century earlier when using statistical tools to measure changes in the number of complete sides of the ‘cells’ of each web and the general regularity of the design. In other words: high doses of caffeine, for example, and because it is the one that produces the most chaotic result, generated disorganized and incomplete patterns. Until the lowest doses they already allowed irregularities to be observed in the web that allowed researchers to correlate toxicity with tissue morphology. Consequences. We must not be a genius for this, but the greater the toxicity, the more incomplete and chaotic the web was. But the most important thing is that this thorough methodology of NASA converted the experiment In an alternative to traditional toxicity tests, especially in a scenario that, as we said, had less tolerance to tests with other types of animals. They were biological evidence, yes, and chemicals were also administered to living beings, but in a little invasive way and without losing rigor. And, precisely, the visibility of this work helped the debate on animal ethics to increase even more, evidencing that alternative, but economic methods could be used, with rigorous and replicable results, being more ethical than other models that were made -and they continue to do. Like Witt’s, NASA’s experiment provided very valuable information, but not applicable to humansdue to the differences between the nervous system of a human and other animals … and that of arthropods. For example, caffeine causes total chaos in spiders, but in humans, although It is not good if we want to make certain decisionsIt does not produce the same effects.

When the town next door is your landfill

by

Some residents of Santa Oliva cross the town next night with their garbage bag, reports 3cat, Catalan Public Radio. They are not visiting, they are going to throw it into the Albinyana containers so as not to have to separate their waste. The panoramic. The Baix Penedès region has become the epicenter of a garbage war between municipalities. Each town has its own collection system: Traditional containers. Smart containers by card. Door -to -door collection. The result is chaos where some neighbors practice what the authorities have baptized as “garbage tourism”: bring your waste to the people next to dodge the recycling standards of the strictest municipalities. The situation has climbed to the Kafkian. In Cunit, The Local Police opens and inspects the bags deposited outside the container in search of receipts, letters or any document that delates to the offender. They have already put more than 200 fines that range between 300 and 3,000 euros. Why is it important. This conflict perfectly reflects the gap between the technological and environmental ambitions of administrations … and citizen resistance to change. Smart containers that require card to open or door -to -door systems with strict schedules guarantee to increase recycling rates. But they also generate a visceral rejection in part of the population, which does not want or cannot have five different containers at home. The result is a spiral of absurd behaviors: Neighbors who sabotage smart containers to leave them permanently open. Others that drive kilometers to throw garbage in the neighboring town. And police converted into waste detectives. Yes, but. Legally, “garbage tourism” inhabits a gray area. Using the container of the neighboring town is not always illegal if its local standards are respected, although it is an abuse of the service that others pay with their taxes. The clearly illegal thing is to throw bags out of containers or do it inside whether there are municipal norms that prohibit use to non -residents. The context. The problem is not exclusive to Baix Penedès. In Sanxenxo (Pontevedra)the cleaning company also analyzes abandoned bags seeking to identify offenders, with fines of up to 600 euros. In Villena (Alicante)the police have identified twelve people in seven months. The municipalities defend that these systems reduce costs and improve recycling. But in Cunit there are neighbors who have not pick up the card for two years to open smart containers. The mayor speaks of “neglect.” The neighbors see it different. Between the lines. Recycling digitalization is creating new marginalized: older who do not understand smart cards, neighbors without a car for the clean point, workers with time -to -door incompatible schedules. “Garbage tourism” is only the symptom of the imposition of technological solutions without social consensus or alternatives for those who are out of the system.

Review with characteristics, price and technical file

by

I travel to 120 km/h on a highway but between the noise, the slight headache and how stuck I go to the ground, I feel faster. I don’t need to go faster, we are fine as we are. There is little left. Just a few kilometers to take the detour to the right and take away a moment in the first town of the Madrid Sierra that is presented to us. It is summer. Still. The sun has not fallen at all but those days of summer decline have already made their appearance. Of somewhat lazy afternoons. Days when the sunset seems to have eaten a quarter of an hour a day before. Of pleasant fresh after a truly infernal August. That is why I stop to the side and leave the central console button tight. I pierce how this Mazda MX-5 is cleared when it separates its retractable roof. He does it in seconds but without hurry. There is no hurry. None. A present that knows past It is exactly what Mazda had in mind when At the edge of the 90s he presented his Mazda MX-5. His Miata. The 80s were characterized by a wild evolution among sports. The turbo put the market above With irrational options at that time. Small missiles like Peugeot 205 or the Renault 5 in turn. At the end of the 80s, the hegemony of Japanese sports. In the early 90s, the Japanese had in hand Authentic supercar. At the same time, a small company did what has been best: go to his air. In full race for power and total traction, Mazda put on the table A small convertible that will resume the philosophy of those of Roadster English with Japanese reliability. It was not, much less, the fastest. Nor did I want to be. His philosophy was the same as today. And although the proven unit does have a clear more aggressive approach, in essence it remains a car sustained by basic and solid pillars: lightness and low price. More than 35 years after their first presentation, the pillars are sustained. Is a 35,000,000 euros car a expensive car? Unfortunately, if you want an alternative to Mazda MX-5 it does not exist. It is the last of its kind. Find a convertible, manual and rear -wheel drive. I have time and I know the answer. The closest thing is a Mini Cabrio But it weighs 300 kg more and has automatic change. Ah, and it’s front traction. He Miata He comes directly from the past and threatens to stay there. Its 142 gr/km of CO2 seem an environmental attack if we take into account that the objective of Europe is to be below 93.6 gr/km of CO2 in the average emission for 2027. If Mazda does not want to receive fines, many electric ones have to sell (The count with plug -in hybrids is no longer so favorable). That or join those who point to zero emissions. With a horizon to choose between electric or millmillionary fines, Mazda MX-5 is a car in danger in extinction. Because its formula is a thing of the past. We have reached a point where the car small, light and enjoyable It seems not to exist. The electric sweeps with the light format. Let’s not say with the pleasure of stepping clutch, move the gear lever and lift your left foot to the rhythm that the right progresses. Know in the past. We will see if it is not there. There is no hurry The MX-5 is particular. Of course, it is not fast. The unity we have between hands comes with a 1.5 Gasoline Motor of 132 hp and manual change. In a market that has been filled with engines driven by excessive power jets (not to mention electrical versions), those 132 hp might seem ridiculous. And they will be for those who seek to cross the car or go with the knife between the teeth. But this is not the approach of Miata. The MX-5 was born to be enjoyed calmly. It is food in a good restaurant where everything comes in due time. Far from the hamburger binge and fried potatoes devoured in 15 minutes. Eye, the second can give us a higher happiness peak, the first is sustained over time. You enjoy seeing how the curve approaches, you reduce one or two marches and step on the accelerator at the exit to stretch an atmospheric engine of those that no longer remain. Without the push of the turbo, enjoying how the needle exceeds the position of the 6,000 rpm with a pleasant linearity. But the best quality of the small Mazda toy is deceive you. Free, play with change and direct the car where you want to feel you are fast. Nothing is further from reality. The noise of being converted, driving from the ground and a minimum asylum are his pious lies. No, don’t circulate fast, it just seems. You do not need good hands to enjoy with the Japanese Roadster and that is a delight for those looking for a car for enjoyable the weekend and, if their circumstances or family allow it, keep it as a daily car. Because that approach away from radicalisms makes the MX-5 be sold as a car for day to day. Especially to enjoy without objection in the most bland journeys, while one weekend you allow yourself to leave without the remorse of being missing a machine that would take much more split in a circuit. It is something that can happen to you with any of the most sporty compact at this time. Practical in day to day but missiles difficult to govern the weekend. I think about this while the car supports and changes the cast of pesos smoothly, while curves link. Brake a little and let a car that comes in the opposite direction. A SUV as another one of those that are sold in our country. Now I … Read more

Four astronauts were chosen in 2023 to see parts never seen from the moon. The wait is coming to an end

by

After A long delayNASA’s Orion ship is practically ready for the first human flight to lunar orbit in more than half a century. American astronauts Reid Wiseman, Victor Glover, Christina Koch and Canadian Jeremy Hansen are the four chosen to see the moon from an unprecedented perspective. What they don’t have yet: a definitive date. The Artemis II mission flight plan The first Crewing Mission of the Artemis program It is the equivalent of Apollo 8 in the new lunar race. Artemis II is not a mission of alunage, but an overflow of the moon with the crew as a novelty of the system. His main objective It is validating that the Orion ship and its rocket, the Space Launch System (SLS), are safe to transport astronauts to deep space. The flight plan of about 10 days begins with a takeoff from Florida and two laps to the earth. The first orbit will last just 90 minutes. The second, much more elliptical, will be extended for almost 24 hours, leading to the crew at an altitude of more than 74,000 km to test the life support systems before flying to the moon. With all verified systems, the Orion Ship Service Module, a Contribution of the European Space Agencywill turn on its engine for a translunar injection that will drive the crew on a four -day trajectory to the moon. The four astronauts will pass about 7,400 km from the hidden face of the moon, traveling farther from the earth than any human being before them. From that point, they will see the moon in the foreground and our planet as a small blue marble to almost 400,000 km away. Thanks to a “free return” trajectory, the severity of the earth and the moon will be responsible for attracting the Orion ship back home without the need for large motor lit, a trip of another four days that will culminate with a meritorious with parachute in the Pacific Ocean. Along the way, They will beat the highest speed that has ever reached The human being. Four astronauts waiting since 2023 In April 2023, NASA He presented the world The four astronauts selected for the Artemis II mission. On the part of NASA, a veteran trio will travel that includes Commander Reid Wiseman and the pilot Victor Glover (both with experience at the International Space Station), as well as the Mission Specialist Christina Koch (the woman who holds the longest space flight record). On the part of the Canadian space agency, which is NASA’s first partner to participate in a manned mission of the Artemis program, the Mission Specialist Jeremy Hansen will go, for whom Artemis II supposes his first trip to space. When these four astronauts were selected, Artemis II was scheduled by the end of 2024. The objective date is not before April 2026. The main reason for the delay is the Thermal shield of the Orion shipthat he did not behave in the expected way in his debut mission. While Artemis I was declared a success, the inspection of the Orion capsule after his return in 2022 revealed something disturbing: the thermal shield had lost great pieces of its protective material. After months of research, NASA identified the cause in December 2024: During the reentry, the gases generated within the ablative material of the shield could not escape correctly, accumulating pressure and causing some parts to detach. Artemis I was a mission without crew, but the phenomenon was not foreseen in the models of their engineers. This problem, together with other technical challenges in the battery and circuits of the life support, led NASA to Read the calendar a couple of timesdelaying Artemis II as of September 2025 and, subsequently, to the current date of April 2026. Everything is already perfectly rehearsed Far from being bored at home, the last days have been a frenzy of trials for the four astronauts. In early August, their costumes entered and entered together in its Orion capsule. Within the ship, already loaded with fuel, they connected to the life support systems and communications, simulating the conditions of the launch day. A few days later, the Orion capsule was transferred to the assembly building Where on August 27 they finished installing the launch abortion system, an escape tower designed to move away the rocket crew in case of emergency. That type of emergencies is also rehearsed. In June 2025, NASA and the United States Department of Defense They made large -scale rescue drills On the Florida coast. Helicopters, rescue paratroopers and recovery equipment practiced how to extract the crew of the capsule in the sea in the worst stage. In Houston, the mission control center has also released facilities. On August 15, the New Orion Mission Evaluation Rooma space where dozens of NASA engineers and its international partners will monitor each data of the ship during the flight. A few days later, they were already doing complete simulations from the new room. Although the main objective is technical, Artemis II will also be a scientific mission. The crew can see the moon from a unique perspective that no one has seen before with their own eyes. And for that reason he has received Intensive geological formation To make the most of the overflow. Although they will not step on the moon, they could be the first humans to see with their own eyes certain regions of the hidden face, such as the Eastern basin. And they have the important task of photographing impact craters and old lava flows, describing textures and colors to help scientists on land to plan the Artemis III mission, the first one that will step on the moon since 1972. If China He doesn’t get it before. Images | POT In Xataka | When the first human being stepped on the moon we all believed that he had abandoned the “earth.” We were wrong

If the question is what to do with the plants on vacation, more and more people are clear: nurseries for plants

by

End of August. Summer is perhaps already in the last ones, but you have a promising first half of September on vacation ahead during which you plan to travel to some sun and beach destination. If you have a dog, cat or even a pogone as a pet there is no doubt what to do with them. In case you can’t leave it to a relative or friend There are hotels They are dedicated to caring for them. But … And the plants? What to do with the ficus of the room or that bonsai that your girlfriend gave you years ago? Do you ask for a neighbor to water him from time to time? Faced with that task, more and more people are clear: nurseries for plants. Wardrobe for plants? Exact. The concept may be shocking, but It is not entirely new. In 2004, the City of Pozuelo de Alarcón already launched a “hospital and nursery” service to help all those neighbors who had problems with their plants. The idea is to advise and offer phytosanitary treatments, but also, remember The Consistory, that the neighbors have a safe place to leave their cactus, ficus, potos and other domestic plants when they go on vacation. On its website, the City Council Clarify In fact, the nursery is open in summer between June 15 and September 15. What are they for? So that when you go on vacation, the care of your plants does not depend on a volunteer neighbor, friend or familiar between time to your home to water and go up and down the blinds. In the nurseries the plants are monitored, they receive care and (if necessary) the staff applies treatments against pests. Philosophy is not very different from that of dog hotels, a type of business that It has spread all over the country. The idea is that when you are not the living beings who are usually in your care do not be disregarded. All. “Plants are living beings, I can’t let them die, I have a responsibility,” I recognized Recently in The country Iván Giacomoni, a neighbor of Madrid who, before leaving his bonsai in a local nursery. “I prefer to take him to a professional rather than ask for favors.” Who use the service? The fan of casuistry is surprisingly broad. They take advantage of plant nurseries people who plan to go on vacation and be out of home for days, but also people who are moving or works and prefer to keep their plants in quiet spaces. There are even those who resort to the service in summer, when the temperature in their homes rises too much, to prevent embarrassment from punishing certain species. Giacomoni is A good example On another reason why people go to nurseries: he usually resorts to service for his Manzano bonsai, a delicate plant and with a high emotional value (it is a gift from his wife) that therefore requires special attention. Entrusting care for a relative or a friend who is not accustomed to that kind of tasks is a concern for the owner and a commitment for those who receive the order. Giacomoni admits that he often collects his bonsai of the nursery much better than he was when he delivered it. What services do they offer? It depends on the nursery. All are basically dedicated to the same thing: caring for plants while their owners cannot do it, but the level of care can vary greatly from one to another. Last year The voice of Galicia interviewed to the person responsible for a Florist of A Coruña with a nursery service that submits to plants an exam to know their status and act accordingly. If necessary, they apply treatments to eliminate pests. In another nursery in the Community of Madrid, they say that, “if necessary”, they even “speak” to plants. “We treat them as if they were family.” Excessive? Before the pandemic in Dubai a garden center decided to go further and offer A summer camp For plants with music and reading sessions. And how much do they cost? Depends. If we talk about the Dubaiti center the first plants can receive at the service without cost, although (At least in 2019) For the following, 7.5 euros must be paid. Here in Spain you can find businesses that take care of plants between 0.5 and € 1.5 a day or between 3 and 7 the week, depending on the establishment and especially the characteristics of the ‘guest’. In the case of the nursery of Galicia, for example, its manager Explain that the specific treatments “are part” and even a home care service is offered for the largest plants. Other nurseries, usually linked to groups and not to private businesses, offer Free services. But … are there so? A quick search on Google confirms that it is not (nor by Asomo) a business as widespread as that of Canine hotels, but it is making its way little by little. TO The initiative From the City of Pozuelo, others have been joining: in the Chamberí area, in Madrid, there is a florist that has decided to launch the service after verifying that many of its customers returned on vacation concerned about the state of their vegetables, and the Circle of Fine Arts also welcomes them Between July and September Without any cost as part of your Climate Refuge Program. Its number of places, yes, is limited. The service is not exclusive to Madrid, or Spain. Can be found in other countries, such as United Arab Emirates, Colombia or United Kingdom. There, in London, a company opened years ago A plant hotel With rooms designed for adapt to its tenants, which includes a spa service with nebulizers. And how are you doing? At least they show that there is a latent need. The web From the Circle of Fine Arts of Madrid it informs that its nursery “is full and there is not even one more pot”, … Read more

A soda giant assaults coffee by buying the owners of Marcilla and L’Or. Now they go for the Nestlé cake

by

There are two worlds when we talk about coffee brands. On the one hand, the numerous toasters and small brands that focus on the Specialty coffee. On the other, a handful of conglomerates huge that copied the shelves of the supermarkets. Nestlé, Starbucks, Lavazza Or Jde Peet’s are some of those giants, but a brand of sodas arrives to take a good bite to the increasing, coffee cake worldwide. As? Buying to one of its main competitors: the holders of Marcilla or L’Or. KDP. They are the acronym of Keurig Dr Pepper, one of the world’s largest beverage companies. This is the result of the fusion in 2018 of Dr Pepper Snapple Group, holders of the 7up or Schweppes brand, among others, and of Keurig Green Mountaina powerful and historical coffee brand that revolutionized the monodosis system in the United States in the 90s both in offices and in homes. They are a giant with a assessment of about 43,000 million euros. The group manages more than 125 brands, but talking about coffee, in the United States they have Keurig coffee makers With own capsules, In the pure Nestlé style with the Nespresso. Well, that megagroup has just launched an operation of 15.7 billion euros to buy one of the largest coffee companies in Europe, the Dutch Jde Peet’s. Jde Peet’s. This is the matrix of emblematic brands such as Marcilla, Saimaza and L’Or in the Café World, but also of Senso or Hornimans, among others. Before the purchase, the company’s valuation was about 13,000 million euros and, Despite all the problems of the coffee sector these last months and price increases, They closed 2024 with a growth of 13.2%, exceeding the forecasts of the 1,250 million euros. Coffee Empire. Although in Europe they remained stable, performance in areas such as Latin America, Russia, the Middle East and Africa was what promoted the company during the last year, translating in an increase of 21%. And, precisely, that is what KDP seeks with the purchase of Jde Peet’s: entering a market that they have not exploited, but in which the brands of the Dutch are well established. To fulfill the strategy, KDP will create two entities when the purchase is closed: Beverage CO and Global Coffee Co. The latter seems like a rebranding of what so far was Jde Peet’s. Objective: Nestlé. This purchase occurs in a context of a Strong up coffee price increase In recent months thanks to a Perfect storm due to factors such as bad crops and shortage problems, as well as a World demand growth Coffee, especially in China. And the group they have in the sight is Nestlé. This giant has its top priority in coffee, Representing About 20,000 million euros in 2024 with brands such as Nescafé, Nespresso, Dolce Taste, Bonka and a strategic alliance with Starbucks to create home products (more capsules). As we read in Reutersanalysts already estimate that this new KDP entity will have a business size similar to Nestlé, both with a 20% share in the global market. Although the purchase is there and there is an agreement between both parties, such an operation should be reviewed carefully, but it is expected to be resolved in the first half of 2026. We will see what happens with its brands, but in a context in which coffee not only crosses problems due to climate change, but Also for tariffsthis fusion between the American and the European makes all the way.

If your intuition tells you that “more intense color are richer,” science has good news for you

Cardiovascular diseases follow being the main cause of death in the worldbut this scourge can begin to control thanks to the most colorful foods of the supermarket. A new and thorough review study systematic published in Nutrients has put the focus on carotenoidsthe Natural pigments that give their vibrant color to fruits and vegetables such as tomatoes, carrots or spinach. What are exactly carotenoids. Carotenoids are a group of more than 600 compounds that plants, algae and some bacteria produce naturally. They are responsible for the red, orange and yellow tones of many foods. Among the best known we can highlight the lycopene that is very present the tomatoes, the beta-carotene that is in carrots (and can get to give us an orange color on the skin) and the Lutein o Zeaxantine that are in green foods. Components of great importance for humans. Humans cannot produce these carotenoids, as with some vitaminsso we depend on the diet to obtain them. But his fame is not free: they act as Powerful antioxidantsneutralizing the free radicals they produce Oxidative stress and ends up damaging the cells and the genetic material itself. In addition, the study highlights its anti -inflammatory properties or its ability to improve the cholesterol profile by reducing oxidation of ‘bad’ or LDL cholesterol. This is something very relevant, then The oxidation of LDL is the trigger to form the atheroma plates In blood vessels, which is a key risk factor for Atherosclerosis. That is, the hardening and obstruction of the main arteries of the organism that can finally cause a heart attack. Evidence on the table: real food vs. supplements. The researchers, led by a team from the European University of the Atlantic in Santander, analyzed 38 of the most relevant studies published in the last decade to answer a key question: does the carotenoid intake prevents cardiovascular diseases? But beyond this, they also wondered if The supplements that can be found work or a varied diet is better. Having them in blood is associated with a healthier heart. The observational studies of cohorts that followed large groups of people for years, are quite consistent: those who had higher concentrations of serum carotenoids presented, in general, a lower risk of cardiovascular disease. Specifically, there was an inverse correlation with hypertension, the rigidity of the arteries and several inflammation markers. This suggests that a usual consumption of rich foods in these compounds is a good cardiovascular health indicator. Do carotene supplements work? This is where the thing is complicated. The studies that gave the participants carotenoid capsules showed results that were often contradictory. On the one hand, when the lycopene was given in supplement, he recorded an improvement in the endothelial function of patients who already had cardiovascular disease, but not in healthy volunteers. In the case of lutein, a triglyceridesand with beta -carotene the significant effect was null. This is something that surprised the researchers, but even more they were amazed to see that by providing several carotenoids together the effect was more effective than with the use of an isolated carotene. This already gives us an important clue. Real food wins the game. The clearest verdict came from dietary intervention studies. When participants were provided with foods such as tomato or carrot juices, or they were indicated to increase the consumption of fruits and vegetables in the diet, the benefits were more notable and consistent than with the pills. Interventions with tomato juice in lycopene managed to reduce key inflammatory molecules in atherosclerosis, while increasing the consumption of fruits and vegetables improved antioxidant capacity of “good” or HDL cholesterol. In this way, scientific evidence suggests that carotenoids have to be consumed in ‘groups’ to have a greater effect. The conclusion is clear: we must not replace the vegetable. On many occasions we try to supplement what we do not like with herbalist treatments. This is not ideal in this case, since the cardioprotective effect of the carotenoid seems to be amplified with other compounds that the original food such as fiber or vitamins presents. But it also adds to the need to complement it with other fruits and vegetables. And you don’t have to become obsessed with tomato and carrot in this regard. There are a lot of fruits and vegetables that can be included in the diet in a varied way so as not to end ‘hating it: peppers, pumpkin, broccoli or kale are some of the examples we find. Time is vital for your protection. As in medicine, the effects are not usually immediate when a change in the habits of a patient is made. In this case, long -term observational studies show the strongest results, that is, It is the sustained habit of consuming these foods What really protects the heart. A good diet is fundamental. This conclusion is no secret to us, since there are many studies that point to important benefits of following a good diet. For example, the Mediterranean diet It can help us stop the aging of the brain. Although it is also a reality that there are many diets such as potato diet either Miracle diets In general, they are a pathology to face it in the absence of nutrients or a subsequent rebound effect.

It is difficult that Mercedes’s position regarding the electric car does not mislead us. His Electric Mercedes It promises autonomies and consumption hardly comparable to any of its rivals. His proposal is that of a car with that of forgetting any plug. Your electric Mercedes, which promises Homologge almost 800 kilometers of autonomy with an 85 kWh battery (ridiculous consumption of between 12.2 and 12.5 kWh/100 km), it looks like the direct heir of the Mercedes Vision EQXX. That prototype, which en Xataka We could tryhe directed his efforts to aerodynamics, very high battery energy densities and very low consumption. That is, the bet was not to achieve the maximum possible autonomy “to the gross”, increasing the battery capacity well above 100 kWh. The way was the opposite, having a lot of energy available but taking advantage of it very little. While the electric Mercedes filled headlines (some for worse), the company insisted again that it had to keep investing in combustion engines. His CEO, at the head of acea, He has sent a letter to the European Commission where he asks for this: flexibility in adoption to the electric car. And yet, in Mercedes it seems that something very fat is being cooking. We do not doubt that other laboratories of car manufacturers are handled juicy things but Mercedes has something good: it takes out its theories to walk. And thanks to that we can see cars like the Mercedes Concept Amg GT XX. Why does an electric car have less autonomy than the announcing 25 records of a tacada Just when the 60s died, Mercedes presented in society a groundbreaking prototype: The Mercedes C111. During its four generations it was shown that this car was the perfect basis where to try each and every one of the advances that the company had in hand. Under his body passed from diesel engines to rotary engines. It is no accident that the Mercedes Concept Amg GT XX It will appear in society with the orange color that identified that mythical sports. A little over two months ago, the company made this public 1,360 hp prototypea 360 km/Hy peak speed a soundtrack of a V8 … that, of course, you will not find it under its body. The technical data were surprising. To get this prototype to become the most powerful and fast Mercedes-AMG ever manufactured, use three axial flow engines (one in front and two on the rear axle) with a battery refrigerated by immersion (we will now see the details) with an 800 volt structure that allow loads of up to 850 kW as a maximum peak. According to the brand, they allow you to recover 400 kilometers of autonomy in five minutes. To this is added an aerodynamic coefficient of 0.198, almost matching the Lucid Air (0.197) and completely closed tires that not only prevents creating turbulence, they are also responsible for the front air flow not diluted in the passage of the vehicle and it is not until the rear axle is overcome when it is dismissed from it. With all these incentives, it only was waiting to see What was Mercedes of When he decided to throw himself to a test track. That happened only a few days ago. Mercedes has put his concept AMG GT XX at full performance for eight days in the Italian Nardò test trackknown for its speed and for being the place where for the first time the Mercedes C-111-IV exceeded 400 km/h. This time, the Germans put their heir to turn to the immense 12.68 kilometers ring. The result was waiting … eight days. Because for more than a week, the Mercedes Concept Amg GT XX has been spinning without rest. The result is that at that time it has managed to complete the whole world. That is, 40,075 kilometers (24,901 miles). Specifically in 7 days, 13 hours 24 minutes and 7 seconds. Not happy with it, the car continued to pushing the barrier of 25,000 miles. On the way the Germans broke 25 long distance records. In the first 24 hours they already reached 5,479 kilometers. The figure was overwhelmed: 1,518 kilometers more tours than the previous record. The formula was simple and effective. Mercedes engineers mounted the pilot, he went to the track and put himself at a cruise speed of 300 km/h. When the battery was exhausted, passing through boxes to recharge at 850 kW of power. Thus, day and night. Day and night for eight days. In total, 3,177 turns of the Nardò circuit of 12.68 kilometers. You can consult all kilometer milestones (and also in miles) In this link. Among the keys that have allowed Mercedes get up with these distance recordsThe company ensures that cooling has been key. They say they have an innovative direct cooling system of the battery fluid. As the components have to face different temperature ranges, it has a central refrigerant concentrator that supplies the specific refrigeration that each of one of it needs. It is also connected to the main radiator and two other wheel arc radiators on each side of the front. Working surgically, you can distribute cooling among all components or specifically send it to the one you need most at that time. Thus, the test has been held in Three pillars: cooling, aerodynamics and recharges time. To guarantee the maximum performance, the company came to install its own medium voltage electric lines, transformers and load stations. Thus, they could have their own high -power load concentrator developed entirely by themselves. In fact, works that extended almost three months were necessary. The result: three loaders with a total power of 2.5 MW. The average of the charges was 850 kW but the company does not specify for how long they were carrying or to what percentage of the battery they loaded with each stop. It is impossible, therefore, to really know the battery capacity used. Photos | Mercedes In Xataka | Solid state batteries are the … Read more

Their companies lack the scale of their rivals

by

The Japan government needs its semiconductor industry to be great again. The biggest. In fact, it was in the past. In 1988 NEC, Toshiba, Hitachi, Fujitsu, Mitsubishi, Matsushita and other Japanese companies hoarded nothing less than 50% of the chips industry. However, Today none of these companies It is positioned among the leaders of A sector dominated with iron fist by Taiwanese, American, Dutch, South Korean and German companies. Japan is currently investing more money in its sector of integrated circuits than the US, Germany, France or the United Kingdom. Not in terms of net value, but its effort is greater if we weigh the investment of these countries on their gross domestic product (GDP). The US dedicates 0.21% of its GDP to its semiconductor industry, and Germany 0.41%. France, according to Nikkei Asia0.2%, and, finally, the United Kingdom 0.04%. The difference is very significant and puts on the table the effort that Japan is making with 0.71% of its GDP. However, this country will not be easy to compete from you to you with Taiwan or South Korea in the integrated circuit industry. Toshikazu Maeda, the general director of the company specialized in the manufacture of equipment to produce Marumae chips, holds that many Japanese companies lack the necessary scale to compete effectively and increase their income. In fact, he regrets that most of the Japanese companies are not growing in full rise of the artificial intelligence (AI). To remedy it, it proposes a solution: smaller companies should merge to grow and be ready to react to the next great opportunity. Rapidus is Japan’s best option to compete with South Korea and Taiwan Japan currently has dozens of very specialized small businesses that manufacture components for ASML either Tokyo Electronwhich are two of the largest manufacturers of photolithography and wafering processing equipment. As Maeda defendsits production capacity is too modest to compete with giants from other countries, such as South Korean companies Samsung or SK Hynix, which produce some of their integrated circuit manufacturing equipment, or the American applied materials, among many others. However, if we stick to the manufacture of Japan Chips already has a company that aspires to compete with TSMC, Intel or Samsung. Rapidus corporation It has been expressly created to replace Japan at the forefront of integrated circuits. Interestingly, it is a very young company. It was founded on August 10, 2022 By the Japanese government With an initial capital of 7,346 million yen (just under 46 million euros) contributed by, and here comes the interesting, Sony, Toyota, Nec, Softbank, Kioxia, Denso, Nippon Telegraph and Mufg Bank. The initial capital invested in the constitution of this company is not very bulky, but there is no doubt that the companies that participate in it have an indisputable relevance in the sectors of technology, automotive and telecommunications. Japan currently has dozens of very specialized small businesses that manufacture components for ASML or Tokyo Electron Rapidus is currently putting a circuit manufacturing plant integrated in northern Japan, in the city of Chitose (Hokkaido), in which it plans to produce semiconductors of 2 Nm. The first prototypes of these chips They are already readybut large -scale manufacturing will not arrive at best until 2027. So far there is nothing really surprising because presumably at that time TSMC, Samsung and Intel will already be manufacturing integrated circuits with comparable lithographs. What is causing the new Rapidus factory to monopolize the looks of the semiconductor sector is that, according to Atsuyoshi Koike, which is the president of the company, it will be completely automated. Its purpose is resort to robots and AI To set up an automated production line that will be specialized in the manufacture of 2 Nm chips for AI applications. Its plan consists, in short, to produce integrated circuits faster, with a lower and more quality cost. To manufacture these semiconductors, equipment of extreme ultraviolet lithography (UVE) produced by the Dutch company ASML, and practically all manufacturing processes are automatic. However, the tests of test and validation, interconnection and packaging of the chips are still largely carried out manually in most manufacturing plants. According to Rapidus, its automation technology of all these processes will allow you to reduce the delivery time of your chips by 66% compared to the times they usually offer TSMC and Samsung. If this Japanese company finally achieves its purpose and its competitors do not improve its efficiency will be able to deliver its semiconductors In a third of the time spent by their rivals. A priori is a stinging enough asset for Rapidus to grow in a perceptible way, although for the moment it is just a conjecture. Whatever this company seems to have everything well tied.
