Massive study confirms direct link to heart damage and mortality

by

For years science has been warning us that ultra-processed they are a danger because of the effects it has on our body. Something that began as a suspicion about nutritional quality has now become a statistical certaintysince ultra-processed foods not only make you fat, but also directly hit the cardiovascular system. With figures. A new study conducted by Florida Atlantic University (FAU) and published just a few days ago in The American Journal of Medicine has put an alarming figure on the table: high consumption of these products is linked to a 47% higher risk of suffering from cardiovascular diseases. And it is not a study that is based on speculation, but the authors have analyzed the data from the National Health and Nutrition Examination Survey corresponding to the period 2021-2023 cwith a sample of 4,787 American adults. How it was done. The methodology is robust because it does not simply look at what participants eat, but the researchers adjusted the results taking into account confounding variables such as age, sex, race, income level and, crucially, smoking. With all this, and eliminating the effect of tobacco and socioeconomic situation of the equation, the result was that those who consume greater amounts of ultra-processed foods are almost 50% more likely to develop heart pathologies compared to those who consume less. It is not an isolated case. If this study were the only one, we might be skeptical. The problem is that it rains in the wet, since the FAU research It arrives to confirm a trend that we had already seen in previous macro studies, consolidating what in science is called a dose-response relationship: the greater the amount of ultra-processed foods, the greater the damage. For this we have the French precedent with a famous studio of the cohort NutriNet-Santéwith more than 100,000 participants, which has already shown that an increase of just 10% in the ultra-processed diet is associated with a 12% increase in total cardiovascular risk. There is more. A meta-analysis published in 2024which reviewed more than a million participants, found a linear relationship in which for each additional daily serving of ultra-processed foods, the risk of cardiovascular events increases by 2.2%. And if we still want more evidence, in Australia A 25-year follow-up of almost 40,000 people linked high UPF consumption with a 19% higher cardiovascular mortality. The new tobacco. The most striking thing about this new research is not only the numbers, but the comparison they make with tobacco and the public health crisis it generated in the 20th century. And while the anti-smoking campaigns achieved drastically reduce deaths due to lung cancer and heart disease, the food industry has filled shelves with products classified as ultra-processed. Because? The mechanism behind this 47% elevated risk appears to be related to systemic inflammation and altered lipid metabolism. It must be taken into account that industrial processing generates polluting byproducts such as acrylamide and uses additives that increase oxidative stress in our body. Basically, the body loses the ability to “cleanse” itself at the cellular level, decreasing antioxidant enzymes and allowing free radicals to damage the inner layer of the vessels, which accelerates the formation of atherosclerotic plaque. This is combined with a nutritional composition with 5 or more ingredients, rich in added sugarssaturated fats and additives, but poor in fiber and micronutrients. A trio that directly impacts blood pressure and insulin resistance, increasing predisposition to diabetes.

The Spanish rail giant escapes millionaire contracts, including the Barcelona Metro. The reason: his link with Israel

by

Basque Caf’s rail manufacturer is in a committed situation after Its inclusion in the United Nations list which points to companies with operations in Palestinian territories occupied by Israel. This circumstance could close the doors of important public contracts, such as The Millionaire Barcelona Metro Contest. In the blacklist. Transports Metropolitans de Barcelona (TMB) has a tender open to acquire 39 new trains worth 321 million euros. The specifications includes a clause that prohibits the participation of companies that appear in the Registry of the United Nations High Commissioner for Human Rights (UNHCR). CAF, current TMB provider, now appears in that list for its participation in The tram of Jerusalem thisa project awarded in 2019 with the Israeli construction company Shapir. The CAF position. The company based in Beasain defends the legality of your contract and denies any violation of human rights. As communicated to the National Securities Market Commission, it has reports from independent experts that support its position and ensures that the project “generates positive impacts on the population” by also providing service to the Arab community with a “inclusive and non -discriminatory” hiring policy. The Alstom turn. The French multinational Alstom, which has a factory in Santa Perpètua de Mogoda, appealed in August before the Catalan Court of Public Sector Contracts against this restrictive clause. However, the recent update of the UN list has retired to Alstom from the registrationwhich now allows you to present to the contest. This exit makes CAF the main affected, since the resolution of the resource will determine whether or not to participate in the tender, whose term remains open until December. More Spanish companies indicated. CAF It is not the only company Spanish in the Black List of the UN, which includes about 160 signatures. Florentino Pérez’s construction company, its SEMI subsidiary and the Ineco public company, under the Ministry of Transportation, also include. CAF is charged with equipment and materials that “facilitate” Israeli settlements, in addition to providing support services and using natural resources, which makes it the Spanish with the greatest reproach by the international organism. A political and social debate. Inclusion in this list does not imply direct sanctions, but yes it has practical consequences. The United Nations urges States to adopt “appropriate measures” to prevent human rights abuse, and administrations such as the Barcelona City Council have incorporated this exclusion in their responsible hiring policies. The debate has also reached the Basque political terrain, where part of the CAF staff starred in concentrations demanding the cessation of the contract with Israel, while the lehendakari Imanol Pradales He has asked that you have “care with the accusations” and has urged the company to make “an ethical reflection”. Implications. Beyond the Barcelona contest, appearing in this registry can affect the reputation of companies, rating rating agencies and access to other public tenders if similar clauses appear in the tender. Public hiring represented 11.55% of Spanish GDP in 2023which turns these vetoes into a relevant economic issue for the companies indicated.

The Neoclouds promised to democratize the AI. Right now are the most fragile and indebted link in the entire sector

by

Coreweave, Lambda Labs, Crusoe and Nebius They represent the most booming and also more fragile link in the AI ​​value chain: Neoclouds. These companies have raised tens of billions in capital and debt to build Data centers full of NVIDIA GPUSbut its business model rests on an increasingly questionable premise: that the demand for computing capacity to continue to grow exponentially. Why is it important. The problem is not just that these companies lose money. Is that its financial structure depends on a vicious circle: They raise debt to buy GPUS. They use those GPUS as a guarantee for more debt. And the money they enter comes mostly from the same companies that sell them the chips and lend them the money. The model. The Neoclouds They came promising GPU infrastructure in months, no years, already prices up to 66% cheaper than AWS, Azure or Google Cloud. The proposal sounded well: companies needed GPUS and Hyperscalers (AWS, Azure and Company) did not supply. The market responded with enthusiasm: Coreweave went from billing 16 million dollars in 2022 to 5,350 million in the last year. Nebius (which has exploded in the stock market and whose germ is Yandex) grew from 5 million quarterly to 105 million. The segment Neocloud As a whole, 82% per year has grown in the last four years. The problem of the single client. Coreweave generated 60% of its 2024 revenues by renting capacity to Microsoft for Openai. Only Microsoft. Nvidia represents another 15%. If you eliminate a The magnificent seven already openai of the accounts of the main Neocloudsthere are hardly 1,000 million dollars of combined income, As calculated by analyst Ed Zitron. Lambda Labs has half of his income at Amazon and Microsoft, plus 1.5 billion in a contract with Nvidia. Almost all Nebius’s growth projection comes from A 19,000 million agreement with Microsoft. There is no diversified market of business clients. There are a handful of technological giants using these suppliers as an exhaust valve or as a vehicle to move money without inflating their own capital expenses Aka Capex. The money trail. Coreweave owes 25,000 million with annual revenues of 5,350 million. Its debt-active ratio reaches 85.4%. It is like two times your annual salary. And unlike the property that supports a mortgage, the GPUS depreciate quickly. Nebius He has just closed a 4,200 million round to build the infrastructure that allows you to fulfill your contract with Microsoft. Lambda Labs and Crusoe have raised hundreds of millions in risk and debt capital. The model is always the same: You get a large contract. You use that contract as a guarantee to raise debt. Purchases Gpus to Nvidia. Rrena more data centers. Repeat. The problem arises when the Ancla client decides that he no longer needs so much capacity, or when you cannot build the infrastructure quick enough. Between the lines. Nvidia has invested directly into several Neoclouds And it is also its largest supplier and, in many cases, its largest client. Coreweave signed a 6,300 million agreement with Nvidia a few days ago For the manufacturer to buy any capacity that cannot be sold to other customers until 2032. In the end we see an elaborate mechanism of Circular financing: Nvidia needs to sell GPUS to maintain its growth. The Neoclouds They need to buy GPUS to fulfill their contracts. The Hyperscalers They need additional capacity but do not want to inflate their capex. And the Private Equity You need to place tens of billions in something that seems the future. In figures. Building a Data Center Capacity Gigavatio costs between 32,500 and 50,000 million dollars. Oracle and Crusoe took 2.5 years to complete a gigavatio for Openai. Nebius has promised to build multiple gigawatts in increasingly unrealistic terms. The alarm signal. Coreweave has reported important operating losses in its last quarter despite explosive growth in income. Nebius plans to reach 1,100 million in annual recurring revenues by the end of 2025, almost exclusively driven by the contract with Microsoft. What happens if Microsoft decides that you can build your own cheaper capacity? Or if Openai, the final customer of much of that capacity, collapses under the weight of their own losses? The decisive moment. The consolidation has already begun. Coreweave has just bought Core Scientific for 9,000 million in shares. Only great will survive, and probably not many. It is a matter of time when the adjustment will arrive. The doubt is how much damage will cause when billions in debt collide against the reality that the real demand for GPU capacity is a fraction of what is assumed.

There are more and more studies that link coffee with living more. And it is very easy to put the leg when preparing that ‘philosopher’ coffee

by

Numerous myths have accompanied coffee during the last decades, Many related to caffeine. However, in recent years more and more studies are investigating the beneficial properties of coffee in our body. Is being related to a Less probability of dying by cardiovascular diseases or with Benefits for our kidneys. There are still unknowns, such as His influence on the brainbut lately the trend is to study the relationship between coffee and live more. And they are finding green sprouts. Lengthening life expectancy. The idea that coffee reduces the possibilities of premature death is something that has been circulating for a while, but this year has monopolized holders because several are published studies In this regard. Tufts University researchers, in Massachusetts, have published a study in which they have related the consumption of one or two cups a day with a lower risk of death due to any cause and for cardiovascular diseases. Fang Zhang is the main author of the study and considers that it is important that the relationship between coffee and longevity be studied, taking into account that “almost half of American adults drink at least one cup per day.” This data can be extrapolated, since coffee is, behind the water, the most consumed drink in the world. The study. To prove that relationship, the researchers studied data from more than 46,000 American adults over 20 years of age who have been collected in health surveys during the last two decades. From that sample, 7,074 people died, and those deaths crossed with coffee consumption. What did they find? That adults who drank coffee showed a remarkably lower risk of mortality due to any cause. A cup of coffee a day has been associated with a 16% reduction in the risk of mortality. With two to three cups dailythe percentage increased to 17%, and with more cups a day no additional reductions were observed. Along the way, they failed to relate the mortality results due to cancer with coffee consumption -another of the Myths They have circulated. The additives. Now, it is not worth having coffee anyway. Bingjie Zhou is an epidemiologist of Tufts that has participated in the study and comments that “few have analyzed how additives could affect that relationship between coffee consumption and the risk of dying.” What additives do you refer to? To the sugar and the saturated fat that can be in the milk, yes, but also in oil and other additions that some chains implement their drinks. When a small amount of sugar or saturated fat is added (present in the aforementioned whole milk, but also in the cream), that beneficial relationship disappears. Therefore, it would be necessary to have coffee only to give the results that the researchers managed to segment. Caffeine. Zhang states that “the benefits of coffee for health could be due to its bioactive compounds,” but also comments that the key does not seem so much in coffee … as in caffeine. And, if the positive effects of coffee disappear by adding saturated fat or sugar, they are also diluted when coffee is decaffeinated. Decaffeinated coffee drinkers have not shown those differences in mortality rates, a conclusion similar to the one they have arrived Other studies that go further to point that the beneficial is the combination of coffee and caffeine, not only coffee or Only caffeine. A monster or a Red Bull would not be worthultimately. It is on the way to the front. Now, both studies are observational, which means that they are limited when examining the cause and direct effect of coffee. In fact, not being a controlled environment, but a simple survey, admit that the lack of a significant association between decaffeinated coffee and mortality could be due to the fact that the consumption of this type of coffee is much lower. As we say, for now those studies that are connecting coffee consumption with mortality are limited, but that several on the same during the last months indicate an interest in knowing that link. In addition, they are the basis for subsequent investigations that analyze how the multiple components of coffee or the time of the day we take it –that is also being studied– It affects that relationship.

The ‘Napier bones’ seem a dominoes, but they are the link between the abacus and the modern calculator

by

The name of John Napier It may not sound to you anything, but I already tell you that, very possibly, it is a person who does not like you. Because what may sound to you is about Neperian logarithms than so many They brought us head in high school. It was Napier who first defined this function, but to “compensate”, he also gave life to what we can consider as the precursor of the Current calculator. Something called ‘Napier bones’ that looks like a dominoes, but that brought mathematical operations to more people. John Napier. This Scotsman were interested in many things. His family was more than settled and, as a good son of wealthy, he attended the University of Saint Andrews at age 13. It did not last long, but not because I would like to leave the studies, but because it went to others Universities of France, Italy or Flanders. Life living from Castillo in Castillo, where he gave free rein to several of his passions. A magician (but not of the numbers). Was a Protestant and considered A black wizard for its neighbors. He was also an ingenious guy. When the pigeons ate their grain, decided Spread wet seeds in alcohol through the field and, with ‘anesthetized’ pigeons and unable to fly, he dedicated himself to capture them. As always, and more when we talk about this type of stories with several centuries behind them, imagination and exaggeration do their job, but what is undeniable is that Napier liked solve problems. His greatest contribution is the one commented Mirifici Logarithmore Canonis Description in which he defined the current logarithms in 1614, but before and then I publish other treaties of the Mathematics field in which he explored how to simplify the calculation tasks. And not only theorized about them or impulse The comma in the decimals: created tools to solve those calculations more easily. The new abacus. Since we need to solve mathematical problems, humanity has sought ways to support tools. This is how the abacoseither The quipus with those who could do simple operations such as sums, subtraction and multiplications. With more complex mathematics, we had to go around the system, and Napier took off his new abacus, or a protocculator. Napier’s bones. In 1617, shortly before he died, the mathematician invented a manual tool focused on facilitating some more complex operations, such as multiplication and division, but also square roots. It was a set of rectangular rods in which the multiplication tables were recorded, in addition to a board with holes for the rods and with the figures of 1 to 9 arranged vertically on the left side. By placing these rods next to the others, multiplications and divisions operations were reduced to simple sums and subtraction, respectively. Originally, they were manufactured in metal or wood, especially, but these rods could also be built in ivory, and a complete game included 10 rods to represent the numbers from 0 to 9. That? Ok, as with mathematics, let’s see examples. One very simple is seen with multiplication, because we do not need to memorize the tables. If we want to know how much 2 x 6, we simply look for row 2 on the right and the rod that begins by 6 and we see what number is in the quadrant: 12. If we want to do an 8 x 8, we repeat the process and we see that we have a 64. If we do a more complex operation, such as 46785399 x 7, we place the rods corresponding to that number (the one that begins by 4, which begins by 6 and so on) next to each other from left to right and we look at the number that comes out in row 7, which is why we want to multiply. Now, from right to left, we are placing the numbers that appear together in the diagonal box: 327497793. Later mathematicians improved the system by creating a board with a 65º inclination that improved the visual identification of that formula, but the ‘Napier bones’ were a revolution when approaching that more complex mathematical calculation to people without higher studies. The only thing that had to be learned was the rule of multiplication and division with the board system. Variants were created, with circular format tablets A jewel. Dying in 1617, it is complicated that Napier saw the transcendence of his theoretical and practical work, but today his logarithmic foundations continue to be used, also the coma of the decimals, a lunar crater bears his name and that Neperian abacus is one of the jewels of the National Archaeological Museum of Madrid. It is not known who manufactured it, but it is a wooden case of a considerable size with 30 drawers in which the sheets of the two abacos designed by the mathematician are stored. One of them formed by 60 numbered rods built in bone and the second, called ‘Promptuario’, composed of 300 numbered and perforated wool chips to perform multiplications. The ‘promptuary’ of the man of Madrid And it’s like a Megachuletasince in the doors of the boxes are the first powers of the digit numbers, the coefficients of the first powers of the binomial and the numerical data of the regular polyhedra. Curious that calculators, apart from being objects with a specific purpose, have become some cases in authentic works of art. To tell the divisumma.

A direct link with Barcelona

by

It doesn’t matter if we talk about art history, science, rebirth, Europe or even History in generalthus, with capital letters. Few figures have been in recent centuries as fascinating as Leonardo da Vincithe great polymata, the genius par excellence. Painter, musician, engineer, scientist (the latter in the extent more broad and precursor of the word) and compulsive writer of notes, Da Vinci has become the maximum exponent of humanism. Until now, telling their lives the biographers have cited mostly two points: The different regions of Italy in which he lived and France, where he died in 1519, with almost 70 years. Now a new work, cemented in a deep research work, establishes a new geographical link: Barcelona. Great painter, huge icon Da Vinci is not just a huge painter and a precursor of modern science. Next to some counted names, such as Van Gogh, Beethoven either Poe (not many more), is part of the group of artists elevated to the category of Pop icon timeless Hence in recent years he has starred tens hundreds of monographs that follow the wake of one of its first biographers, Giorgio Vasari. Only in the last decades they have investigated in the life of the Tuscan (sometimes putting the focus on some concrete aspect of its legacy) Fritjof Capra, Michael White, Frank Zöllner either Charles Nicholl either Walter Isaacsonknown for his biographies Steve Jobs and Elon Musk And who in 2017 dedicated a monumental work to Leonardo. Now that vast list is added an essay of more than 600 pages written by the teacher Carlo VecceExpert in the Renaissance. Its title cannot be clearer and gives an idea of ​​to what extent the book aspires to be a total compendium about Da Vinci: ‘Leonardo’s life’. To prepare it, Vecce has examined the painter’s manuscripts and divered in files And historical records, which has allowed him to enrich the image we had so far of the author of ‘La Gioconda’. Along the way, it has also reached some amazing conclusions. One of them is Leonardo’s family link with Spain. More specifically with Barcelona, ​​where he moved part of your family time before the painter was born in AnchianoVinci, in 1452. In fact, to find the connection with the city, you have to go back to the time of Leonardo’s great grandfather and grandfather, to whom his commercial vocation took him to the Spanish coast. To establish the link, Vecce starts talking about Guido Di Michele, a key figure in Leonardo’s family tree for two reasons. First, for carving a hole in the influential guild of Florentine judges and notaries between 1330 and 1360. Second, for their two children: Giovanni and Piero, great -grandfather of the future painter. Although both brothers studied laws and were admitted to Guido’s profession, over time they ended up following different paths. Piero made career as a diplomat and became a notary of The Signoria. Giovanni however decided to break the tradition and try fortune in Barcelona. That I opt for the city is no accident. In his work, Vecce remembers that Barcelona was “one of the capitals of the Mediterranean world “in which a rich community of Florentine merchants also prospered. Giovanni was installed near Santa María del Mar (under construction) Together with his wife Lottiera and managed to make his son, Frosino, dedicate himself to the lucrative trade of luxury fabrics and dyes Between Mallorca and Valencia. Leonardo’s link could have been left in that distant branch of his ancestors if it were not because one of Piero’s children, perhaps tired of life in Tuscany, was attracted to the life that his uncle Giovanni and his Frosino cousin like merchants in Barcelona took. His name was Antonio and the dessert would be remembered for being the father of being Piero Da Vinci. That is, Leonardo’s grandfather. Instead of following the footsteps of his father in Florence, Antonio moved to Barcelona and for almost 15 years he worked hand with Frosino, dedicating mainly to the sale of Spices and raw materials for the textile industry. Vecce recounts how Leonardo’s grandfather navigated the Mediterranean, between Barcelona, ​​Valencia, Mallorca and Morocco, and reached Fez, although over time his activity focused on Barcelona. When he was already 40 years old, Antonio decided to take a new turn to his life and Return to Tuscany. The exact reason is not known, but that decision would be crucial for Leonardo. Back in Italy Antonio started from scratch, he married a notary’s daughter and in 1417 he returned to Vinci, where the family lived from the few family income. His tight economy did not prevent marriage from having several children: Guliano, Violante, Francesco and Piero Frosino. We are interested in the latter, the eldest of all and who in the 1440s decided to move to Florence to resume the family tradition initiated by Guido Di Michele and become a notary. If Piero has gone down in history, it is not, however, because of his study of the laws or the role he performed in the capital of Tuscany, but for his son. In 1452 he had An illegitimate rod With a woman named Caterinaa healthy, creative and intelligence creature only surpassed by its very powerful curiosity. They called him Leonardo. Leonardo da Vinci. His father and mother would end up following different paths, marrying other people and having more offspring; But Piero soon realized his son’s talent for drawing and worried that Leonardo could train as an artist In Florence at the Pintor Academy Andrea del Verrocchio. The rest is already history. Who was the mysterious Caterina, her own past and her family is another investigation route that creates new links for Leonardo and in which Carlo Vecce also investigates in her work. But that is already subject to Another report. Images | Wikipedia 1 and 2 and Logan Armstrong (UNSPLASH) In Xataka | A drawing by Leonardo da Vinci hid a hidden map.
