We Spaniards have been calling all donuts with holes “donut” all our lives. Now it is private property of Bimbo

November 19, 2025 by usatoday24

Cases of all types and types pass through the Supreme Court table. That’s nothing new. What is curious is that its magistrates rule on a lawsuit in which pastries, linguistics and brands are combined, all well mixed in a legal dispute so full of chiaroscuro that justice has taken a while almost a decade in reaching a conclusion. As if that were not striking in itself, at the center of the dispute was one of the most famous sweets in the country: Donut. We explain ourselves. Word of the RAE. If you open the RAE online dictionary and type “donut” you will see that the meaning From the word is clear, at least to academics: a donut is basically a “spongy, donut-shaped piece of pastry, fried and usually glazed or covered in chocolate.” A type of donut. The RAE also clarifies that the term comes from the registered trademark Donut. The million dollar question is… Is donut (like that, in lower case and with an accent) the same as Donut? Does the fact that the first word has been in the Royal Academy’s dictionary for years allow any Spanish company to use it freely or is it the exclusive property of the company that popularized it, Bakery Donuts (Bimbo), owner for decades of the DONUT brand and others that have included the term? Almost a decade of lawsuits. The above questions are more than just questions thrown into the air or theoretical reflections. They are at the bottom of a dispute that may date back to beginning of 2017when a long legal tug-of-war began centered on the word “doughnut.” Around that time, Bimbo Donuts Iberia filed a lawsuit before the Commercial Court No. 9 of Madrid when it detected that another third-party company (Atlanta Restauración Tematica) was offering donuts on its website that, although they were called Redondoughts, were described as “doughnuts.” For Bimbo, this represented a violation of its trademark and it decided to sue. Why’s that? The Confidential has had access to the last ruling in the case, which allows us to understand the arguments put forward by both parties. For Bimbo, the fact that another company used the term represented two things: first, a use of its brand, which has been cared for for decades; second, an example of unfair competition that affects their interests in the candy market. For Atlanta things are different. In your opinion“donut” is nothing more than a word in common use, a word recognized by the Royal Academy. As if that were not enough, he claims that he has not even used it “as a trademark”, but rather on his website, where at the time it had an “insignificant” reach. In fact, the company is dedicated to selling to professionals in what is known as ‘Horeca’ channela label that basically refers to establishments such as hotels, restaurants and cafes. To the Supreme. Bimbo’s claims were unsuccessful in the first instance. Not in second either. As remember Five Days, This last court even recognized that the word donut is descriptive, in common use and appears in the RAE dictionary. The multinational did not give up and the issue ended up in the Supreme Court, which is the one that has had the last word. The most curious thing is that for its magistrates the reality is somewhat different than for previous judges. “It cannot be ignored that the use of the same word by Atlanta may imply per se an improper use of the reputation or notoriety of the Donut brands, with the consequent impairment of their distinctive character and reputation,” reasons the ruling of the Supreme Court, which even speaks of the risk of “loss of prestige.” “The third party unfairly benefits from the attractive power of the brand.” In case there were any doubts, the ruling recalls that Atlanta did not exactly use the term RAE (with a lowercase letter and an accent), which leads the court to point out that the company did not act in a “loyal” manner towards the “legitimate interests” of Bakery. “It affected its renown, distinctive character and exclusivity,” he remarks. An armored brand. The conclusion? Whatever the RAE says, the unauthorized use of the word ‘Donut’ for commercial purposes (at least in Spain) violates the rights brand of Grupo Bimbo. Hence the multinational spoke of a “historic legal victory.” In his opinion, the ruling recognizes “the renown” of his brand and grants it “maximum protection.” In reality, since Atlanta has already removed the word from its website and its use was “limited,” it does not impose compensation or a fine.

There were thousands of mysterious holes lined up in Peru. We didn’t know why until a drone saw them from the air

November 12, 2025 by usatoday24

In the arid hills of Pisco Valleyin the south of Peru, extends a monument as mysterious as it is precise: a strip of almost a kilometer and a half made up of some 5,200 perfectly aligned cavities, known like Mount Sierpe or the Band of Holes. Discovered in 1931 by the geologist Robert Shippee and Lieutenant George R. Johnson during one of the first aerial expeditions over the Andes, the site baffled generations of archaeologists. Until now. A mysterious landscape. For decades, theories were proposed ranging from its defensive use to fog capture or water storage, but none of them quite fit. Now, a new study published in Antiquity provides a convincing hypothesis from a point of view that no one had valued: from the air. In this way, Mount Sierpe would have functioned as a accounting and barter system on a large scale, a kind of “spreadsheet” of the pre-Hispanic Andes. The geometry that speaks. The international team of researchers, led by archaeologist Jacob Bongers from the University of Sydney, used drones to map the site with millimeter precision. Aerial images revealed an organized structure into about 60 blocks or sections, each with distinct alignments and regular number patterns. Some areas show rows of nine by eight holesothers alternate between groups of seven and eight. This internal order, absent any defensive or agricultural logic, suggests an administrative purpose. Sediment analyzes extracted microscopic remains corn, totora and willow (plants traditionally used to make baskets and mats), which suggests that the cavities were lined with plant fibers and were used to store goods, possibly in packages or braided baskets. The holes of Mount Sierpe From local barter to administration. Researchers believe that Monte Sierpe was born as a space for exchange between highland and coastal communities, an organized market for balance the flow of goods in the absence of currency. Products (for example, corn, coca or cotton) could be deposited in each cavity as a visible representation of the value of one good compared to another, allowing quantities to be compared in a public and transparent manner. Centuries later, with the expansion of inca empirethat system would have been reinterpreted and expanded as an accounting tool to manage the tribute of local populations. Each block of holes would have corresponded to a different community group, and the variations in number and arrangement would reflect the contribution levels or work shifts required by the Inca State. In essence, Monte Sierpe would have been a physical data recorda stone matrix destined to organize the unwritten economy of the Andean world. A carved khipu. The most revealing finding is the similarity between the structure of the site and the Inca khipusthe rope systems with knots used to record censuses, taxes or resources. One of the khipus found near Pisco presents around 80 groups of lacesa figure surprisingly close to the 60 segments of Monte Sierpe. This correspondence suggests that the Band of Holes could have been a three-dimensional khipua monumental version of that woven numerical language, designed to coordinate the flow of goods and work between communities. Unlike the tablets or inscriptions of other civilizations, the Andean peoples turned geography itself into a support for information. Code in the desert. If you also want, Monte Sierpe redefines our understanding of pre-columbian organizational intelligence. Without writing, without currency and in a hostile environment, Andean societies managed to develop a visual, modular and mathematical method to represent their economy. Each hole would have been a cell a great living recordmanaged collectively, perhaps accompanied by ceremonies or ritual exchanges. Thus, in its apparent geometric simplicity, this “spreadsheet” carved into the rock reveals a advanced economic systembased on reciprocity and communal control of resources. What for the first explorers were simple rows of holes now emerge as the physical testimony of a civilization that, centuries before European contact, had already found its own way of turning the landscape into memory.

We have detected the greatest fusion of black holes seen to date. It is a problem for our theoretical models

July 19, 2025 by usatoday24

One of the enigmas that most intrigue astronomers is that of Black holes of intermediate size, those black holes halfway between the holes of stellar mass and the supermassions such as the one that dominates in the center of our galaxy. These are black holes with masses between 100 times that of our sun and those that multiply this star mass by millions. GW231123. A group of Ligo-Virgo-Kagra (LVK) collaboration researchers (LVK) has announced The detection of the greatest clash between two black holes registered to date. The discovery has occurred thanks to the gravitational waves generated by the impact, whose signal has been called GW231123 by those who detected it. November 2023. The name of the signal refers to the date on which it was observed, on November 23, 2023. The study of the detected waves led those responsible for the new study to estimate that the resulting black hole had a dough some 225 times higher than that of our sun. Until now the most massive had been “alone” 140 solar masses. It was in 2021, the GW190521 signal. Estimates indicate that the 2023 signal was the result of the collision between a black hole of 100 solar masses with one of 140 solar masses. That is, only one of the black holes was already as massive as that of the fruit of the largest shock detected so far. From this event not only highlights its magnitude, but also the fact that the speed of rotation of black holes was surprisingly high. A new enigma in heaven. All this planet an important unknown for the team. As they explain, the holes of such mass cannot be formed from the death of a star, at least based on what contemporary physical models say. The only way we know can be formed is through the fusion of smaller black holes. LVK. In 2015, the Ligo experiment made history detecting for the first time the clash of two black holes through the expansion of gravitational waves associated with such a violent event. This pioneering experiment has been company in Europe and Kagra for years (Kamioka gravitational wave detector) In Japan. Together they have already detected more than 300 clashes between black holes. The details of the study They have been presented In the 24th International Conference on General Relativity and Gravitation (GR24) and 16th Conference Edoardo Amaldi on gravitational waves, a joint conference held this week in Glasgow, Scotland. Not so easy to observe. The detection of GW231123 “pushed the limits of both gravitational wave detection technology and current theoretical models,” says the responsible team. Analyzing these types of events through gravitational waves is not easy, but knowing more about them can help us unravel some key mysteries of the cosmos. “Black holes seem to turn very quickly, almost to the limit of what is allowed by Einstein’s theory of relativity,” explained in a press release Charlie today, co -author of the study. “This makes the signal difficult to model and interpret. It is an excellent case study to push the development of our theoretical tools.” Looking for the midpoint. Theoretical tools that perhaps help us reveal the secrets of the elusive black sized black holes. Today we do not know very well how these holes are formed whose mere existence implies the certainty that we still do not know about our universe.

A quantum solution for black holes

July 6, 2025 by usatoday24

The two families of physics They have not spoken for 100 years. Einstein’s general relativity describes with centenary precision The large-scale universe: how the planets, stars and galaxies deform the space-time fabric. On the other hand, quantum mechanics explains the strange and tiny world of subatomic particles. Both theories form the pillars of modern science, but are fundamentally incompatible. Unifying them in a single theory of “quantum severity” is, for decades, The Holy Grail of Physics. New research suggests that the key to achieving this could be hidden in the heart of the more enigmatic objects of the universe: Black holes. The impassable wall of physics. The problem is simple and the time incredibly complex. Quantum mechanics has managed to explain three of the four fundamental forces of nature: electromagnetism, strong nuclear force and weak nuclear force. Gravity, however, resists him. General relativity, our best theory of gravity, falls apart in the most extreme environments of the universe, precisely where quantum effects should be crucial. The clearest example of this rupture is the singularities, the theoretically infinite density points that are found In the center of black holes. For physicists, an infinity in an equation is an alarm signal that indicates that the theory has reached its limit. “We believe that general relativity only works on large or ‘macroscopic’ scales, but that in very short distances, or microscopic scales, it must be replaced by a quantum theory of gravity,” He explained to Space.com Theoretical physicist Xavier Calmet, author of a new study published in Europhysics Letters. A new recipe for black holes. Until now, string theory was the main candidate for this unification, in the absence of experimental verification. But Calmet and his team have adopted a different and surprisingly effective approach. Instead of a complete and finished quantum theory, they have used what is known as the “effective action of Vilkovisky-Dewitt” to calculate universal quantum corrections that should be applied to Einstein’s equations, regardless of the underlying theory. When applying these corrections, the team discovered something fascinating: in addition to black holes that arise from general relativity, there must also be holes born from “quantum solutions.” And it is not simple adjustments to the black holes we already knew. “They are completely new black holes that exist in a world of quantum gravity,” explains Calmet. New theoretical objects that emerge from the same mathematics, but with a quantum “flavor.” What all this means. Einstein’s relativity works great for huge things such as planets and galaxies (a continuous world); and quantum mechanics, for the tiny, like atoms (a world to jump). When it comes to explaining black holes, relativity predicts a singularity, an infinite density point that, in practice, tells us that the theory does not work anymore. What these physicists have done is to use a mathematical “patch” to add the basic quantum rules to relativity. This patch is the action of Vilkovisky-Dewittdeveloped by physicists Georgy Vilkovisky and Bryce Dewitt. In doing so, they not only fixed the “error”, but discovered that the new rules allow the existence of a completely new type of black hole, one that simply could not exist according to Einstein’s old rules. Can we ever see them? The study details how these solutions can be built near the events horizon, the border from which nothing can escape the black hole. Although these quantum solutions are theoretically different, distinguishing them from their classic counterparts is, for now, an almost impossible task. The most significant differences manifest very close to the horizon of events, a region that we cannot observe directly. “The astrophysical black holes that we are observing well could be described with our new solutions instead of those of general relativity,” Callmet concludes. “As both theories match great distances, it will be difficult to propose evidence capable of differentiating between the two types of solutions.” The theory shows that it is possible that There are black holes within a frame of quantum gravity. But the secrets of quantum gravity remain fiercely saved by these cosmic titans: the response to the greatest enigma of modern physics is not in a particle accelerator, but quietly orbiting in the darkness of space.
