Dogs are getting uglier and uglier. And science has several reasons to explain why we love that.

by

In 1989, journalist Margo Kaufman reported in the Los Angeles Times how a stranger shouted “Hey, ugly!” upon seeing his two pugs walking down the street. It was not an isolated case, in his chronicle he commented that the derogatory comments accumulated day after day. At the time, these dogs were seen as comical anomalies, far removed from the prestige enjoyed by the German Shepherd or the Labrador. Three decades later, the world has turned upside down. What used to provoke ridicule today generates fascination. The networks have been filled with hairless Chihuahuas, toothless Chinese Cresteds, bulldogs that snort like locomotives and identical Brussels Griffons still Ewok. The phenomenon is as visible as it is undeniable: we are falling in love with ugly dogs. The rise of ugly dogs. The most compelling data It is contributed by The Wall Street Journal: As of 2022, the French bulldog is the most registered breed in the United States, displacing the Labrador retriever after 31 years of absolute reign. And it is not an isolated case: pugs, Brussels griffons, Chinese crested dogs and peculiar chihuahuas accumulate searches, followers and adoptions. Although Spain does not have a record as exhaustive as the United States, the trends point in the same direction. Industry platforms place the French bulldog, Chihuahua and other small and striking breeds among the most in demand in big cities, a symptom that aesthetics ugly-cute It is also gaining ground here. As explained by Elias Weiss Friedmancreator of The Dogist account, people look for dogs that stand out, animals whose appearance attracts attention and says something about the owner. Social networks as an amplifier. The aesthetics ugly-cute (translated as cute, but ugly or funny) is a fashion promoted by influencers and celebrities, who boast on Instagram of their pugs (either pugs) either french bulldog (either frenchies), contributing to normalize—and popularize—its extreme appearance. And contests also help: in 2025, the winner of the historic World’s Ugliest Dog Contest It was Petunia, a hairless French bulldog, rescued in Oregon. The contest may sound ridiculous, but its function is to make dogs from shelters and illegal breeders visible and facilitate their adoption. Ugly sells and moves. However, this trend is not sustained by virality alone. There are deep psychological mechanisms. But why? The general health psychologist Alejandra de Pedro González explains to Xataka that the fascination with the “rarest” dogs responds to a very human instinct: taking care of the vulnerable. “We associate certain traits—lameness, hairlessness, deformities—with a need for protection. That activates our most basic prosocial instinct,” he points out. This impulse is not exclusive to our species. Scientist Konrad Lorenz defined in 1943 the baby schema: a set of childhood traits (big eyes, round face, small nose) that trigger caring behaviors. Many “ugly animals” share these exaggerated traits: bulldogs and pugs with flattened snouts, Chinese crested dogs with prominent eyes, chihuahuas with disproportionate heads. The researcher Marta Borgi, in a study published by the scientific journal Frontiers in Psychologyexplains that these traits increase the willingness to protect and reduce aggressiveness towards the individual. Beyond tenderness. According to De Pedro, unusual dogs allow you to project an almost human personality: “With a strange dog you can almost invent a personality,” he details. This fits with what picks up The Wall Street Journal: owners who describe their dogs as elves, babies, literary characters, or even tragic souls. Crooked faces, prominent eyes or disproportionate bodies become emotional canvases. In addition, these breeds require special care—fold cleaning, respiratory medication, constant checkups—which strengthens the bond. For the psychologist, this emotional investment is a form of parentification: “In an individualistic society, people look for someone to take care of. An ugly dog ​​is the ultimate expression of unconditional love, it doesn’t even have to be cute for you to love it.” The dark side of the trend. Brachycephalic breeds—pugs, French and English bulldogs, Boston terriers—suffer from severe respiratory problems, difficulties regulating temperature, eye diseases, and infected skin folds. Veterinarians cited by The Wall Street Journal They describe these extreme cases as “medical nightmares.” Countries clike Holland and Norway have banned the breeding of some breeds for violating the animal welfare law, by perpetuating characteristics that condemn the dog to a life of pain. In fact, studies from the Royal Veterinary College show that English bulldogs are more than twice as likely to suffer from diseases compared to other breeds and have a drastically shorter life expectancy. Even so, owners and breeders resist changes: some people They think it’s “funny” the snoring or noisy breathing of pugs, without understanding that they are clinical signs of suffering. The (im)perfect beauty. Petunia, the hairless bulldog crowned in California, doesn’t know that she has been on the front page of newspapers. Nor has it fueled a global debate on aesthetics, vulnerability or animal welfare. He only wags his tail when someone approaches him. And perhaps therein lies the true explanation of this contemporary obsession. In a time that demands perfection —symmetrical faces, ordered lives, polished bodies—, ugly dogs offer us the opposite: unconditional tenderness. It doesn’t matter if they have a crooked tusk, a milky eye or a snorting snout. His way of loving does not change. Perhaps that is why we look so much for these unlikely animals: because, when we look at them, we recognize that tenderness remains a basic human need that does not understand symmetries.

Drones revolutionized warfare in Ukraine, now they are going to do it all over the world with one final trick: changing shape

by

If something has become clear after these years of war in Ukraine, it is that drones are no longer a mere complement from the battlefield: they have become a such transformative technology like gunpowder or the Kalashnikov, and are entering a second, even more disruptive phase, driven by artificial intelligencethe miniaturization and the accelerated production. Their next landing is planetary. The second revolution. As we said, drones have gone from being tactical support to becoming a structural factor of modern warfare. Ukraine has shown that an inferior actor in means can degrade a great power with cheap swarms air, naval and land. At the same time, insurgencies, militias and states with few resources use the same logic to compensate for conventional disadvantages. The result, as we will see below, is a global diffusion of precision capabilities at low cost that reduces own risks, complicates defense and makes conflicts more accessible and resistant to resolution. War spine. The trajectory of drones goes from radio-controlled experiments in world wars to smart cruise missiles and platforms like the predator and the reaper in the “war on terror.” The recent turning point is Nagorno-Karabakhwhere an average country combined decoys and UCAVs with artillery to neutralize anti-aircraft defenses and dominate the air without powerful traditional aviation. Since then, the central lesson is that no need be a superpower: simply integrate drones, sensors and indirect fire intelligently to alter the tactical balance. Ukraine as a laboratory. In Ukraine, the drone design, testing and tuning cycle has been compressed to weeks. kyiv has scaled from imported platforms to its own industry that produces millions of unitscombining FPV, reconnaissance, long range and fiber optic guided systems to circumvent Russian electronic warfare. The proximity between workshops and front allows for rapid iterations on sensors, frequencies and flight profiles. Russia responds with mass production and specialized units like Rubikon. The front thus becomes an environment where each innovation is copied or counteracted in a very short time. Swarm globalization. The intensive use of drones has extended to conflicts with a lower media profile. In Africa, dozens of states and non-state actors have built-in armed UAV to internal wars, with markets dominated by exporters such as Türkiye and China. In Myanmar, rebels have converted commercial drones into a substitute for artilleryforcing army withdrawals. In Gaza, Hamas used them to blind Israeli sensors before raids. This shows that technology not only balances power relations, but also increases lethality and makes subsequent stabilization difficult. AI, ammunition and fire economy. The AI integration Drones transform the economy of combat: the cost per useful impact decreases and precision increases. Now there are kits software and hardware that allow existing platforms to locate, track and attack targets with limited human supervision. The practical effect is to reduce the need for classical artillery and increase the efficiency of fire, both on land as in sea. However, this does not eliminate the value of artillery or manned platforms, but rather shifts part of the fire load to systems more fungible and scalablewith clear implications for budgets and logistics. The new unmanned spectrum. And here comes one of the big changes, possibly the least expected. The drone family is expanding and transforming, changing shape and size: from nanodevices for close reconnaissance to enormous ships and underwater vehicles autonomous. The former allow discreet exploration in urban or closed environments, and the latter expand the presence on the surface and under the sea without embarking crews or assuming their risks. Between both extremes, ukrainian naval systems, Chinese XLUUV or AUV as the Ghost Shark redefine surveillance, anti-submarine warfare and area denial operations. The common pattern is to eliminate the need to protect lives on board, making it easier to accept high-risk missions and speed up production. A new generation of contractors. Companies like AndurilAuterion or Shield AI operate with startup logic: short development cycles, strong software integration and commitment to assuming own risk before winning large contracts. Some choose to control the entire chain (hardware and software), others to offer “operating systems” applicable to multiple platforms. This puts pressure on traditional, less agile contractors, and reconfigures the industrial ecosystemwith more mid-sized players competing in specific niches (loyal squires, swarms, mission software). The result is greater speed of innovation, but also more fragmentation of solutions. China, the US and the race. China part with advantage in commercial drones and transfers that leadership to the military fieldwhile investing very heavily in countermeasures after observing the performance of cheap drones in Ukraine. The proliferation of manufacturers of anti-drone systems and directed energy weapons indicates a strategic commitment to control both attack and defense. The United States, despite the accumulated experience, appears out of date in volume and in anti-swarm systems, with dispersed programs and irregular financing, which forces to emergency measures to accelerate purchases and use dual suppliers. This anticipates a long race in which quantity, cost and active defense weigh as much as the individual sophistication of each platform. Strategic limits. This point is often not taken into account. The destructive capacity of drones can lead to overestimating their strategic impact. From there what spectacular operations against high-value infrastructure do not always translate into lasting changes in the control of territory or in the political will of the adversary. Controllers like Radakin they underline that drones and algorithms do not replace the need for a coherent strategy or forces capable of occupying and holding ground. The temptation to build campaigns based on high-visibility specific hits can generate a dangerous gap between tactical success and strategic results. The era of eternal wars. All this breeding ground leads to a final scenario: by reducing costs and risks for those who prolong the combat, drones favor conflicts. no clear outcome. Statistics show fewer decisive victories and fewer peace agreements since the 1970s, while stagnant wars increase. In this context, drones provide continuous capacity for harm to actors who would otherwise be forced to negotiate or give in. The probable result is more long wars, distributed … Read more

We have found a very rare “hybrid” blood type that only three people out of half a million have

by

At school they taught us a basic rule of the biology of our blood that would accompany us throughout our lives: o we are A, or B, AB or else O. He ABO system of the blood discovered by Landsteiner For more than a century, it has been the pillar of modern hematology and is essential for performing a transfusion or transplant. However, genetics has a habit of reminding us that biology does not follow the dogmas we have been taught in textbooks. Other blood types. The ABO system is undoubtedly the majority in our species and that’s what we’re completely used to handling. But the reality is that there are other groups that are really minorities, like the one they have discovered a group of researchers from Thailandwhich has confirmed what seemed like a statistical anomaly. In this way, after analyzing the blood of 544,000 people, they have found a “hybrid type” of blood that It is extremely rare. So rare, that in that massive sample only three people own it. And this is not only a challenge for the different health systems that must have greater control over blood transfusions, since giving blood that is not compatible to these patients can be a death sentence. A goal. The study, carried out by researchers linked to the National Blood Center of Thailand and recently reviewed, started from a brute force premise: mass analysis. By screening more than half a million donors, the goal was identify rare phenotypes that escape the standard typing tests used in hospitals for the majority group. And so much so that they have achieved it. What they found in this case were three subjects who did not fit the usual patterns. This was not simply a rare blood type (as AB negative might be in certain populations), but a genetic structure that defies the Mendelian genetics that are classic in the human blood group. And to see it in magnitude, of the 544,000 subjects, only three presented this variant, which means that it has a prevalence of 0.00055%. Hybrid blood. Once we know how rare it is, the question becomes clear: what is hybrid blood? In general, it is necessary to know that the blood group is determined by a series of antigens that are on the surface of the red blood cells that travel through the bloodstream. These antigens are placed there by specific enzymes. If a person has enzyme A, they will be blood group A. If they have enzyme B they will be group B and if they have both they will be AB. And this is where the deep science comes in: the ABO gene is incredibly diverse in our environment. What these three individuals present seems to be a variant of what in hematology known as cis-AB phenotypes or B(A) hybrids. Instead of inheriting an A allele from one parent and a B allele from the other, they possess a mutation that allows a single allele to code for both enzymes at once, or create a “mutant” enzyme capable of performing both functions. A confirmation. This is an idea that On paper it looked very good.especially after research that pointed to the possibility of a hybrid enzyme that had both functions. Now the Thai team has only confirmed that this phenomenon really exists in humans. The problem of transfusions. We might think this is just a curiosity for geneticists, but it has real implications. If one of these three people needed an urgent transfusion and was misclassified with a standard test, the consequences could be fatal, since they would develop a major immunological reaction at the time of being transfused, which would seriously put their life at risk. All this because the immune system is ready to attack everything that is foreign, that is, everything that does not resemble what is inside. Thus, if blood is transfused that has small modifications to the red blood cells, it can react by destroying them and creating a potentially fatal reaction. It is not an isolated event. Although this may seem like an oddity that has only now been discovered, the reality is that there are many blood types that fall outside the classic ABO. One of the most curious It is known as ‘golden blood’ where you are neither Rh positive nor negative, but null. This makes him a universal donor (hence his name), but the problem is that he can only receive transfusions from his own blood group, which is extremely rare to find. Although it is not the only one, since we have rarer groups such as Gwada-Negative which is accompanied by other important neurological symptoms.

The bridge with the largest steel span has completed its most difficult challenge. And it’s in China, of course.

by

There is not a month that does not release one mega constructionand in that area, China leads with an iron fist. Both due to the magnitude of his works, the technique used or the land they save with the structurethe Asian giant has become an example of perseverance when it comes to creating, above all, infrastructure that connects all its regions. After the highest bridge in the world, in the province of Chongqing, they are involved with another record-breaking bridge. One with the largest steel span in the world. Fenglai Daxi River Grand Bridge. As is often the case with these works, something that stands out as much as its magnitude is the construction time. In just three years, they have up a bridge in an extremely complex area. It clears two cliffs and the causeway will be 310 meters above the water surface. But more than because of the terrain, if it is news for something, it is because of the opening, that space between two columns. The total length of the bridge will be 1,136 meters when it is finished and the span is almost half of it: 580 meters that are suspended leaning on an arch-shaped structure made of steel. The height The arch in its central part is 116 meters and both the photos and videos show the complex lattice-type structure. Precision. More than a whim, it is necessary if you want to bridge that distance while looking for a bridge that can withstand both the weight and the possible tremors that are frequent in the region. To build the structure, engineers turned to BIM methodology (either Building Information Modeling) that simulates by computer all the processes of both the construction of the structure and its future maintenance. This is common, but essential in this lattice structure where many embedded components require an accuracy of less than a millimeter of deviation. On November 28, the team complete the union of each of the pieces weighing more than 300 tons that form that great puzzle of the lattice span, and now it remains to create the road that will consolidate the union between regions. Necessary. Because the Fenglai Daxi River Grand Bridge is not simply a feat of engineering: it is a catalyst for something China is aggressively pursuing. The country wants to carry out an economic and social transformation of the most challenging regions of its geography, and the Chongqing region falls into those plans as it has a large number of mountain ranges that have traditionally challenged communication with large centers. When completed, the bridge will be part of the Wu-Liang Expressway that will link the urban center of Chongqing with the Wulong district in approximately one hour, when with the current detour it takes approximately three hours, having to do a mountain route. And it is just one piece of a much more ambitious plan, which includes 52 construction projects, more than 1,200 kilometers of highways and a total investment of 155 billion yuan, about 19 billion euros. Megathings = tourism. Thus, the bridge will seek to become an element that will facilitate the flow of goods between the regions, but also of people with the objective of promoting tourism. Currently, in Wulong About 350,000 people live there and it has traditionally been a poor area due to the soil not being the best for farming and its natural isolation. However, since 1994, tourism has transformed it, especially since the Karst Geology National Park out including on the UNESCO World Heritage list in 2007. Now, Wulong aspire to become a global tourist destination, and this improvement in infrastructure seems key to achieving that goal. Furthermore, it is no longer just that China’s megaconstructions facilitate mobility: The buildings themselves are designed with the aspiration that they become points of interest. An example is Huajiang Grand Canyon Bridgean immense construction 625 meters above the level of the river that is used to cross from one side to the other, but It has a cafeteria and some adventure activities. Another is the Three Gorges Damwhich can not only move the axis of rotation of the Earthbut it also has a museum that documents the construction, an example of how the dam itself works and multiple observation points.

It also changed engineering forever

by

Shortly before 11:00 a.m. on November 7, 1940, an impressive American suspension bridge was minutes away from becoming engineering history. In that mass there was only one dog trapped that no one could save. After a few minutes after 11, the cameras filmed one of the most shocking scenes ever recorded. This was the story of a huge failure. A too light masterpiece. When the Tacoma Narrows Bridge opened in July 1940, its fine and elegant silhouette was intended to symbolize a new era of engineering economic and structural efficiency. Leon Moisseiff, one of the most prestigious engineers in the country and architect of the Golden Gate, had designed a stylized colossus that, however, from day one began to show a disturbing behavior: The board vibrated and waved even in moderate breezes. The workers named the structure as “Galloping Gertie”a nickname as colloquial as it was revealing, because it indicated that something deep and still misunderstood was disturbing its stability. First investigations. The University of Washington teams began intensive studies: scale models, wind tunnel tests and emergency solutions such as hydraulic jacks and temporary cables. Nothing managed to stop the oscillations. The bridge, too thin, too light, too faithful to a refined aesthetic, had been pushed to the limit by the design philosophy of the Great Depression, one in which materials were reduced to the essentials and aerodynamic resistance was not yet a mature science. The disaster. On November 7, 1940, with winds of around 65 km/h, Gertie experienced what she researched defined as “an abrupt transition between the usual vertical oscillations and a violent torsional movement that soon became unmanageable.” Motorists and reporters experienced scenes that seemed taken from a fantastic story: sections of the ground that disappeared underfoot, jumps in the void between undulations, and a torsion rhythm that intensified until the structure folded in on itself. At 11:02 in the morning, the center of the bridge fell into the strait. The only victim was Tubby, a dog trapped in an abandoned car. The show, filmed with a chilling sharpnessbecame one of the most influential visual documents of modern engineering. What the hell happened. After the fall, investigations determined that the collapse was due to an unknown phenomenon then in its complexity: the so-called as torsional flutter. When one of the suspensions gave way, the deck adopted an asymmetrical geometry that allowed the wind to feed the bridge’s torsion. The structure was no longer agitated by the atmosphere: it was its own movement that generated the destructive force, not the wind. The “self-excited” oscillation grew without limit until it caused a total fracture. That tragedy buried the classic theory of “deflection,” which held that only vertical movements were relevant in a suspension bridge, and forced the development of new aerodynamic principles and a rigorous standard of wind tunnel testing that has since been applied around the world. Bridge opening day in 1940 Reconstruction and correction. In later years, the United States rewrote the manuals of bridge engineering. A more robust replacement was designed, with a wider skeleton, heavier cables and open grilles to reduce wind action. “Sturdy Gertie,” opened in 1950, corrected the conceptual errors of its predecessor and became the symbol of a lesson learned through catastrophe. Decades later, in 2007, it was added a new section to absorb the growing traffic. And while engineers built a safer bridge on the surface, the underwater world began to claim the remains of the original bridge, which lay scattered more than 60 meters under the waters of Puget Sound. Collapse day Unexpected metamorphosis. In an extraordinary way, what began as an accidental shipwreck ended up becoming one of the artificial reefs more extensive and unique of the Pacific Northwest. In the depths of the strait, twisted beams and ruined metal plates were covered with anemones, sponges, algae and layers of organisms that transformed the tragedy into a hive. underwater life. Wolf eels snaked through the knots in the steel, giant Pacific octopuses found refuge in the folds of the collapsed deck, and schools of fish prowled the rubble. For divers, it was a palmost mythical landscape: a metal forest colonized by marine life, so exuberant that it gave rise to the legend of a gigantic “Octopus King” which, according to the inhabitants of Tacoma, reigned in the shadows under the bridge. The magic of that accidental ecosystem was that nature took a vestige of human engineering and turned it into a sanctuary. Depiction of Tacoma Narrows Bridge Collapse Threatened legacy. However, as the decades passed, the environment changed disturbingly. Various witnesses who dived in the nineties describe an underwater garden brimming with faunabut today, most of that splendor has disappeared. The overfishingcombined with ecological changes in the Puget Sound, has dramatically reduced the presence of iconic species. Sea creatures and giant octopuses have migrated In less exploited areas, the fish are smaller and in many sections only remains of hooks and gear remain. The least affected points are, paradoxically, those found under the current bridge, where fishing is complicated and marine life resists. Still, for many expertsthe deterioration of the artificial reef is a reminder of the vulnerability of unintentionally created ecosystems and how human intervention (on land or sea) defines which life thrives or disappears. History, memory and protection. Galloping Gertie’s remains were included on the National Register of Historic Places in the 1990s, not only as evidence of a failed engineering landmark but also as a testament to nature’s ability to transform ruins into habitats. Today some defenders aspire to an even higher status: turning the site into a marine reserveprotected against extractive activities and recognized both as ecological heritage and as a fundamental chapter in the history of engineering. An extraordinary failure. If you also want, the history of the Tacoma Narrows is not only that of the bridge collapsebut that of a double transformation: that of engineering knowledgewhich evolved as a result of the disaster, and that of underwater ecosystem that emerged from the … Read more

everything was fine until he forgot the password

by

That let’s forget a password It is a fairly common mistake that normally does not have major consequences, but there are cases in which things are more serious. Today we learned the story of a man who has forgotten the password for a chip he has implanted in his hand. And there is no way to get it back. What has happened? They tell it in Futurism. The protagonist of our story is called Zi Teng Wang and a few years ago he thought that implanting an RFID chip would be fun for his magic shows. As narrated in your Facebook pageAfter trying several uses that did not convince him too much, he programmed the chip so that when scanned with a cell phone a meme would appear. One day, the link where he had hosted the image stopped working and when he went to change it, he realized that he had forgotten the password for the chip, so now he has a chip in his hand that redirects to a broken page. A solution. It is not possible to use the classic “I forgot my password”, so Zi Teng Wang has consulted with friends who are technologically savvy and they have told him that the only option to regain access is to hack the chip. Simply use an RFID reader and try all possible combinations. The problem is that you have it in your hand, so you would have to strap the reader to your hand or remove the chip. In the end he decided to let it be and is glad that the link to the meme worked again. Biohacking. In 2016 it was very fashionable about implanting RFID or NFC chips in the body. RFID technology is the same as that used in the chips that are implanted in dogs and cats, while NFC is what we usually use to transfer data between mobile phones or pay. These chips do not have a battery, but rather work passively by “responding” with identification when a reader approaches. Years ago there were people who did it to be able to open doors or unlock your computer simply by reaching out and also to pass your contact information. Currently, the original biohacking has been eclipsed by more ambitious proposals that aim at extreme longevity with figures like Bryan Johnson and more advanced technologies such as the brain chips proposed by companies like Neuralink. epic forgetfulness. Being left with a chip in your body that is useless is a chore, but it is even fun when compared to other cases of forgotten passwords. In 2021 we learned the story of a German engineer who lost your bitcoin wallet passwordwhose value amounted to 256 million euros. And it has not been the only one, it is estimated that there are at least 3.7 million bitcoin lost for the same reason.

Ford CEO is completely obsessed with Chinese electric cars

by

“Xiaomi is the Apple of China.” These are the words not of just anyone, but of Jim Farley, CEO of Ford. The boss of the American company is one of the bosses who has been the most talked about in recent years. And the reason is approach when studying rivals. It is rare to see the CEO of a company praising a rival, but Farley not only does not mince words, but is determined to air the details that need to be improved to catch up. And if there’s one thing that’s catching Farley’s attention, it’s Chinese cars and, in particular, the Xiaomi SU7. Knowing the competition. The automobile industry has embarked on electrification, and if this adventure is making one thing clear, it is that China is leading the way. Although Tesla struck first from the West, it is the Asian giant’s companies that are pushing both technology and batteries. This is generating an ecosystem in which chinese cars They are extremely competitive in the market, something that is making Western manufacturers nervous. To better understand his competition, Farley had the idea of ​​carrying out a series of trips to China to select cars to take back to the United States. Not to dismantle them – or not only – but to drive them on a daily basis on everyday trips. In a recent interview with La Naciónstates that the entire management team is going on that trip to choose 50 cars. He doesn’t want to get off his SU7. Of those 50, they keep five, and they are the ones they take back to Detroit. The one chosen by Farley? He Xiaomi SU7. He liked it to the point of saying that “it’s fantastic,” stating that he didn’t want to get off of it. Previously, already rated the company as “an industry giant and a much stronger consumer brand than automotive companies,” but now it has gone a little further. The Apple of China. “Everyone talks about the Apple car, but the Xiaomi car already exists and it is fantastic,” said before the official cancellation of the car was known. And, in fact, in that interview for La Nación, Farley commented that he is not surprised that Xiaomi is so successful. “It is the Apple of China.” Precisely, it is the “ecosystem” that stands out, something that is Apple’s strong point: “You get into the car with your phone and you don’t have to pair it because it automatically identifies it. It has facial recognition, an AI assistant and can accelerate from 0 to 100 km/h in three seconds with just the push of a button. It looks like a porsche taycan”, he assures. Humiliating. Is it perfect? “No, and we could surpass it in the segments in which we compete,” adds the manager. But Farley’s ‘flowers’ are not only for Xiaomi, but for the Chinese industry. At the Aspen Ideas Festival held in June of this year, CEO described what he saw in China as “lor most humiliating thing I have ever seen in my life”. The reason? That 70% of the world’s electric vehicles are manufactured in China and that they have cabin technology much superior to that offered by many Western brands. “Automatically, your entire digital life is reflected in the car.” Technology gap. Farley’s interest in competitors, both Chinese and domestic, is evident. When Ford entered the electric segment, He did it like an elephant in a china shopwith a Ford Mustang Mach-E which was very expensive to develop when its competitors already had much more optimized processes that allowed the price of cars to be lowered. Since then, they have been changing strategy and moving chips. They hired Doug Field, former chief engineer of the Tesla Model 3 and member in Apple car design, and was the one who opened cars to Farley. Field sincere: “Jim, your parts release system and development architecture are 25 years behind. You can’t compete like that with BYD”. The acid test will be the new electric pickup that Ford is preparing for 2027 with the aim of making it affordable. We will see, of course, how the market responds, but what is clear is that Farley does not fall short when it comes to praising the competition.

If you want your body to be biologically eight years younger, science has a recipe for you: vegan diet

by

We humans have many desire to appear as young as possiblealways seeking eternal youth. This has meant that its search has ceased to be the exclusive terrain of the alchemy to become one of the hottest fields in biotechnology, with many treatments that seek to literally make us younger or even extend our lives. Now, the vegan diet It is at the center of supposed iron health, and science has wanted to verify whether consuming it leads to an increase in the years of life. The twin experiment. Traditionally, doing research on how a person ages has been a problem because of genetics. And comparing two therapies between two people to see if they age more or less quickly makes us wonder if the result is due to the treatment or diet or because one of the members has very good genetics. To eliminate this variable from genetics, science has found the best way to work: use identical twins. In this way, their genetics will be exactly the same and the effect of the intervention we perform will be directly related. The study. They recruited a total of 21 pairs of healthy adult identical twins. One of each pair was assigned a healthy omnivorous diet; on the other, a strict vegan diet. In total, for eight weeks the impact was measured using epigenetic clocks with algorithmic tools that estimate biological age based on in DNA methylation. Methylation is the process by which small chemical groups called methyls are added to certain parts of DNA with the aim of being able to ‘turn genes on or off’, causing some instructions to be read and others not. Something that is related to agingsince it changes over time. The results. In this case, what the researchers saw was very interesting, because despite the short time the diet was maintained, it was found that the vegan group showed significant reductions in estimated biological age. This is something that was seen in decreased DNA methylation in pathways related to inflammation and metabolism. All of this adds up to improvements in fasting insulin and a reduction in LDL cholesterol, leading to better old age. But although everything seems very good, caution was already requested with these results. Because. It’s okay that the vegan diet seems to offer good results, but the big question is why this happens. And the summary tells us that it was not just because they left meat aside, but because they stopped eating in general. This is the most important point, because the vegan group consumed fewer calories simply because the calorie density, and therefore the calorie restriction in the end It is one of the few methods which has been proven to extend life in animal models. This also adds up to weight loss, as the vegan participants lost more weight than their omnivorous counterparts. Critics point out that rapid weight loss can alter epigenetic markers on its own, regardless of the food source. The problem. Although the fact of being on this diet for such a short time and under the study means that longitudinal research is still needed to know if this translates into years of real life gained. And although the biological clock slowed down in this case, researchers warn about the long-term risks of having a poorly planned vegan diet. One of the consequences is the vitamin B12 deficiencyalthough today the supplementation that is done in foods makes this a minor problem. Added sugar. The other culprit of aging and to which we pay less attention. A study published in 2024 I was quite clear about the consequences of its consumption, in some cases without knowing it because we did not read the labels of the foods we consumed. In this case, a study with 242 middle-aged women used epigenetic clocks to measure cellular damage to correlate it with their consumption. The results in this case were quite clear: each extra gram of sugar added was associated with an increase in epigenetic age. However, there is a brake that we find in our Mediterranean diet, which is rich in vitamins, minerals and antioxidants. That is why eliminating up to 10 grams of added sugar per day could reverse the biological clock in approximately 2.4 months. The lesson. Scientific literature points out in this case that what matters in food is quality, not just the label. This is why a varied diet with fruits, vegetables or legumes is directly associated with lower mortality and a decrease in chronic diseases. On the contrary, a vegan diet that is based on ultra-processed foods (even if it has very little meat) can be really harmful in the end.

Every time you think you’re eating poorly lately, think about these Neanderthals who ate their neighbors.

by

Approximately 40,000 years ago, a group of Neanderthals captured girls and women, took them to the vicinity of the Goyet caves (in present-day Belgium) and ate them. And no, it’s not a figure of speech. What is a girl like you doing in a place like this? Although the third Goyet cavern has been studied since the 19th century, it was not until a few years ago that tomographic techniques, ancient DNA analysis and isotonic measurements have allowed us to fully understand what was happening in the heart of the mountain. And we have seen the best example a few days ago in Scientific Reports, Quentin Cosnefroy and a large team of European researchers have managed to identify a minimum of six individuals among the mass of bones to be studied. At least four were adult or teenage women of short stature and surprisingly fragile bones. And that in itself was quite curious: why was the proportion of women so high? But it wasn’t the most curious thing: the most curious thing is that they had been eaten. Hunger. According to the analysis, virtually all of the bones show cut marks, fracturing for marrow extraction, and other signs of processing for human consumption. But the most striking thing is the selection: it is not a random group, but a very specific demographic sample. I have already said the key: the bones were too graceful to be Neanderthal bones (who, remember, populated the caves at that time). The isotopic studies showed that none of these individuals came from the vicinity of Goyet: that is, they were women from other groups who (as I said) were captured and taken to the cave to be consumed with tools. They were a banquet. And no, I’m not going overboard with sensationalism. The same study acknowledges that the statistical probability of finding such a gender and age composition is ridiculous. “The exclusive presence of women and children in the Goyet complex does not respond to chance or a sample of natural mortality. It is a deliberate selection,” said Christian Pérez. And he was right. The only reasonable explanation is exocannibalism; something that had only been identified in modern ethnographic contexts as a form of violence towards groups (in the context of tribal wars). As the authors pointed out, this interpretative key is what can help us understand what was happening. The last living Neanderthal. Little by little, the question of what happened to the Neanderthal universe becomes more accessible to us. In fact, “the appearance of extreme behaviors such as selective cannibalism could be interpreted as an expression of growing tensions” and that clears up many doubts about what could (and could not) happen. As much as the theories on assimilation gain strengththe truth is that this admiration was not a bed of roses.
