In 1985, on the verge of being defeated by Pepsi, Coca-Cola changed its ancestral formula. The result was a disaster

by

Coca-Cola had been the reference soft drink around the world for decades, but in the early 80s a very tough competitor had emerged: pepsi. The firm had been gaining more and more followers with advertisements in which they participated Michael Jackson, Michael J Fox either Cindy Crawfordand its success did not stop growing thanks to a spectacular advertising campaign called “The Pepsi Challenge”. Those ads seemed to show that people preferred the taste of Pepsi, and Coca-Cola managers, scared by the threat of being forgotten, decided to change the formula and create the so-called “New Coke.” That was a disaster and Coca-Cola ended up returning to its original formula. The Pepsi challenge was as simple as it was effective. The people who participated did a “blind tasting”: there were two glasses with unidentified cola, one with Coca-Cola and the other with Pepsi. In appearance they seemed the same, and behind them were the bottles with which each glass had been filled (or hidden under some paper cylinders). The result according to the advertisements was always himself. The taste of Pepsi won time and time again. Coca-Cola executives, who saw how their market share was constantly declining, began a gigantic project: the creation of a “New Coca-Cola” (New Coke) that would see its recipe modified for the first time since the creation of this drink in 1886. What happened The modification of the recipe was evaluated with market studies that were promising: the new Coca-Cola, sweeter, beat both the old Coca-Cola (the original) and Pepsi. Everything seemed to show that Coca-Cola had its winning drink. That made the company announce “New Coke” with great fanfare on April 23, 1985. Initially the reception was good, but criticism soon began to arrive, which increased: a lot of people wanted the old Coca-Colaand surveys conducted shortly after the launch showed how only 13% of people preferred “New Coke.” Coca-Cola ended up producing the original recipe again, which it called “Coca-Cola Classic” just two months after that launch, and some time later it directly stopped manufacturing its “New Coca-Cola” to stay with the classic, which also lost that adjective. Everything remained as at the beginning, but with a spectacular marketing failure and development in which the firm had invested 100 million dollars. Still, Coca-Cola recovered after the disaster. That attempt to compete, although a failure, seemed to resonate deeply with consumers, especially when Coca-Cola recognized its mistake and offered the “old Coca-Cola” again. By the end of 1985, Coca-Cola Classic was outselling New Coke and Pepsi. What happened? One of the problems was pointed out by Malcolm Gladwell in his book ‘Intuitive Intelligence: Why do we know the truth in two seconds?’ (‘Blink: The Power of Thinking Without Thinking’). In it he explained how the failure was in the nature of the blind tastings, based on “sips.” People, he explained, reacted positively to the sweeter taste of Pepsi when they only tried a sip, but that taste ended up being worse when you drank an entire can, and that is what according to Gladwell Coca-Cola failed to understand in its tests. The original Coca-Cola recipe proposed a much more appropriate balance for the capacity of the cans and bottles of this soft drink. At Coca-Cola they also tried to investigate what had happened, and the conclusion of those in charge was that they underestimated the public reaction of people who rejected the change. The response generated by that launch of the “New Coca-Cola” was astonishing, and signature collections and movements against the new recipe were organized that united many people in an unprecedented campaign. Of course: New Coke kept winning those blind tastings. It didn’t matter: the one that really won was Coca-Cola, whose current quota in the soft drink market is 44% in the United States, while Pepsi’s is 26%.

We have been blaming hygiene for our allergies for almost 40 years. Ancestral DNA has just shown that the problem is more complex

by

Every time a child develops a asthmarhinitis or eczema, one of the questions we ask ourselves is why it happens, and one of the ‘culprits’ we point to is excess cleaning. Right now it is a reality that we live in environments that are too neat, using disinfectant gel all the time and not letting the little ones play in the mud because logically they can get stained. However, science here has ‘traveled’ to the past to find out the origin of allergies. What have they done? Here two new and massive studies based on the analysis of prehistoric DNA are putting the famous “hygiene hypothesis“And the paradigm we face now is that the evolutionary adaptations that our immune system has developed over the last 10,000 years to survive pandemics, curiously, are designed to protect you from allergies, not to cause them. A return to the past. To understand the plot twist, we must go back to 1989 where epidemiologist David Strachan proposed the hygiene hypothesis. Here it was proposed that the lack of exposure to microbes during childhood in most modern societies deregulated the immune system, since it literally did not grow with good training under its belt. In this way, it was proposed that, by not having real pathogens to fight against, the body created an imbalance that caused the immune system itself to attack substances that are not actually a threat, such as pollen or mites. And it seemed to make sense. A genetic journey. The first blow to this hypothesis has been dealt by a great published research in Nature this same month of April. Here the researchers analyzed almost 16,000 ancient genomes from individuals who lived thousands of years ago. What they discovered here is that the transition to agriculture in the Neolithic changed everything, since human societies became dense, we began to coexist closely with animals and, with this, large-scale infectious diseases arrived. But these pathogens that we began to face, despite the many deaths they generated, also favored hundreds of immune variants to ensure our own survival. But there is more. This is where parallel research that is revolutionizing our understanding of asthma and autoimmunity comes into play. Here is an article preprint has crossed ancient DNA with the modern complete genome with the aim of looking for differences between our DNA and that of our ancestors. Logic dictated that a system “revolutionized” by evolution to fight bacterial and viral infections of the past would be the cause of today’s allergies. But the data show exactly the opposite, as the study reveals that genetic variants that were positively selected in recent millennia have strengthened defenses in “barrier tissues” such as the intestine, against pathogens, but at the same time reduce allergic inflammation. The variants. Among these defense genes We have, for example, LYZ, which codes for lysozine, a fundamental antimicrobial enzyme in our secretions that destroys part of the bacteria. We also have FUT6, which is involved in protein fucosylation, a process vital to the interaction between our mucosal immune system and the gut microbiome. Why are we allergic, then? If our genetics have been evolving for 10,000 years to protect us from allergies in the lungs and intestines, the question is inevitable: why do cases continue to increase? Here science suggests that the problem is not simply an excess of cleaning in the present, but a profound imbalance. In this way, we do not need to catch diseases or live surrounded by human society, but the problem is that our immune system, genetically adapted to the strong pathogenic pressures of the first agricultural societies, expects to encounter a series of commensal microbes in the environment. The ‘problem’ is that these microbes are no longer present in modern cities and that is why the genes we have with a protective function cannot do their job correctly.

If the question is how to shield the mountain to fires, in Soria they have an ancestral solution: luck of pines

by

With tens of thousands of hectares calcinedhundreds of evacuated people, several deceased and an environmental and economic impact that can only be completed with the passing of the weeks, these days do not abound the good news related to forest fires. On Thursday 13, however COLLEGE OF ENGINEERS OF MONTES (Coim), He presumed in networks of an “ancestral formula” that has allowed part of the rural population of the provinces of Soria and Burgos to get rid of the harassment of the flames or, at least, look at the summer with some more peace of mind. His name: “Good luck of pines.” In a place of Soria … For days in Spain, talking about fires is to do it of calcined hectares, evacuations and confinements. That is why it attracts even more attention if it can be published on Thursday A thread of very different tone. In him he remembers that the Pinares regionbetween Soria and Burgos, it seems to have found a formula to reduce the impact of forest fires. And that in the area, between the Natural Park of the black lagoon and the glacier circuses of Urbión, is one of The biggest pine forests from Europe. Click on the image to go to Tweet. Three words: luck of pines. “In the Soriana de Pinares region of Pinares more than 20 years ago there is not a great forest fire. Magic? No … call it ancestral forest management,” starts the school before specifying that the key to that apparent armor in front of the fires is in the “Good luck of pines”“an ancestral management model” that for centuries confers to the neighbors a series of rights and duties over the mountain. Moreover, Coim remembers that a few days ago ray caused a fire conato in Vinuesa, the head of the region, but was suffocated shortly. “Chance? No”, Remar. on Wednesday HERALDO DE SORIA He spoke Of several fire alerts that did not go to adults in the areas of Tera, Gómara and Vinuesa, where in the early morning, around 7.45 h, a fire was detected, probably caused by lightning, which was stifled only one hour later, at 8.42. The intervention of several environmental agents, together with a fire endowment, allowed the flames to raze a reduced surface, of 0.01 hectares of grass. What is the fate of pines? As COIM points out, it has nothing magic. The fate of pines is a way to manage forest resources, a system that goes back centuries ago, to PUEBLAS LETTERS granted during the Middle Ages and has helped establish a strong link between the local population and forests. “This deep link with the forest has created a community that not only lives from the mountain (wood, hunting, mushrooms, tourism), but actively protects it,” They point out from school Before remembering that the formula includes coordination between institutions, prevention systems and continuous surveillance. Going down to detail. Said so maybe it sounds abstract or diffuse, but Philosophy The system is actually very simple: what it raises is the distribution among the members of a community of forest resources such as the wood extracted from municipal pine forests. The cast is made through lots and the beneficiaries must meet certain requirements that guarantee their roots and link with the town, among other things it helps to generate a feeling of local belonging. “The fate of pines is a system to distribute forest exploitation of wood and wood that is integrated into a community such as a practice that has been maintained for centuries uninterrupted thanks to the will of the municipalities and the inhabitants of the peoples, responsible for perpetuating this ritual, transmitting it from generation to generation as a symbol of cultural identity and belonging to the community” explained The Junta de Castilla y León in December, when it decided to declare the well of intangible cultural interest. And how do they do it? “The enjoyment of the lots is carried out through periodic concessions of luck or wooden shorts to the neighbors,” The Board abounds. “These are use divisions in equal portions, lots or lots, which are subject to raffle among the beneficiaries. For a long time, the cast was materialized in kind, with the wood itself. In recent decades, the need to facilitate management and conservation tasks has resulted in the preparation of lots that, once sold, give rise to distribution of money.” Those responsible for controlling and preparing the register of beneficiaries are local municipalities or entities, which sometimes require those who participate that they meet some requirements, such as having roots in the town or taking some time living there. Right now it expands through the regions of Pinares Soria-Burgos and Pinares Llanos de Almazán, for which they extend According to the Junta de Castilla y León to about 100,000 hectares of native forest mass. Is it so old? The truth is that yes. The Board itself recalls that the first written references date back to the 16th century, although its history is actually richer. “The privilege by which the kings granted the right of use that was obtained from the mountains, through letters villages and privileged letters, dates back to the Middle Ages with the repopulation of these territories,” remember. With the passage of time, during the seventeenth, eighteenth or twentieth centuries, the practice was consolidated. At the beginning of the last century, luck was reflected at the legal level through special ordinances and statutes, “turning a situation of fact into a law.” Beyond its tradition and roots, the Board highlights its advantages, as its effect to “link” the population to their environment or its effectiveness to fight depopulation. “It benefits the inhabitants who reside in those locations”, Point out The Government. “It is also an important economic contribution to the community.” The Soriana formula. Whether the pine suertes the key or one more piece of the Forestry Management Formula of Soria, the truth is that for a long time different media The same question have … Read more
