The eternal battle between whether you are from Apple/iOS or Windows/Android intensifies because the AI ​​wants to take advantage: Crossover 1×36

In the world of technology there are usually two main types of users: those who choose Apple’s closed ecosystem, and those who prefer to bet on (somewhat) more open alternatives such as those proposed by Microsoft with Windows and Google with Android. Is there a way to know which of the alternatives is better? Into that mess we get into this new episode of Crossover in which we analyze what a technological ecosystem is and the evolution of this concept. Thus, we review how Microsoft began to implement that idea without still using the word “ecosystem.” He did it with Windows because with it he had that central element on which to sell us other applications like Office or Internet Explorer in those beginnings. But with smartphones and the cloud, the ecosystem concept ended up making complete sense, and If there is someone who has exploited it in an extraordinary way, it has been Apple. It has done so, however, with a closed focussomething that has clear advantages, but also disadvantages. Faced with this conception, Microsoft first on desktop computers and then Google on mobile phones continued to promote open ecosystems, which gave much more choice but also posed their own problems. Added to all this now the rise of AIwhich these companies will undoubtedly try to use as a new argument to strengthen their ecosystems. They are all doing it already, and it remains to be seen whether or not this reinforces these ecosystems, whether open or closed.

We already had an ozempic to lose weight, now someone has created one for the eternal youth: NAD+ promises

Of the six -digit operations In elite operating rooms to luxury serums That they promise to erase wrinkles in minutes, the eternal youth industry has always played with the same idea: that somewhere there is a shortcut. But what if the secret was not in a cream or in a scalpel, but in a tiny molecule that lives in each of our cells? This is how NAD+is presented, the coenzyme that has gone from being a laboratory concept to become the new biohacking grail. The ozempic of being young. As happened with the GLP-1 drugs in The obsession with thinnessNAD+ has become the aspirational shortcut towards youth. Hollywood and the aesthetic elite have embraced him within the call “Invisible luxury”: undetectable results, continuous maintenance and therapies that combine apparatus with cosmetic biology. In that stew of mass access, supplements and “shots” of NAD+ they occupy the biohacking story. From Hollywood A Amazon. A couple of years ago, Hailey Bieber and Kendall Jenner They popularized Intravenous NAD+therapies, a format that Miami and Dubai clinics sell as an energy and anti -aging “booster”. But it is not just celebrity thing: a search is enough on Amazon to find NMN or NR capsules that promise to raise cell levels. The problem is that, As The New York Times has warnedthe scientific evidence that supports these habits is still weak. In addition, what appears on the label often does not match what is in the bottle. A study led by the gerontologist Andrea Maier detected deviations of up to 100% in the real content of supplements, regardless of brand or price. Shining the NAD+. Better known as Nicotinamide adenine Dinucleotide, is something like the spark that allows our cells to work. It is everywhere, from the muscles to the brain, and According to the University of Navarra Clinic Participate in such critical tasks as producing energy, repairing damaged DNA or activating syruches, proteins linked to aging. The problem is that, over the years, NAD+ levels plummete and begin to relate to memory loss, muscle weakness and an increase in the risk of diseases associated with age. Therefore, raising those levels by precursors such as NR or NMN can keep mitochondria and favor cell longevity. Initial essays, collected by the confidentialThey have documented improvements in memory, movement and metabolism. However, they are small studies and experts They agree that they are missing Essays to convert the promise into solid evidence. Experts ask for prudence. Enthusiasm coexists cautiously. According to the webmd medical portalnicotinamide is safe to 900 mg per day, but high doses can cause headaches, fatigue, gastrointestinal problems or enzymatic alterations. In the case of nicotinic acid, another form of related vitamin B3, can cause redness and decreases in voltage even in moderate doses. The University of Navarra Clinic Explain that Supplements can interact with medications that affect liver or coagulation, so it is recommended to use them only under medical supervision. In a more concrete way, they probably do not damage in moderate doses, but there is also no certainty that it is worth taking risks for something that still has no macros studies. A society in search of shortcuts. NAD+ fever fits into a broader cultural context: obsession with shortcuts against aging. Hollywood has gone from “Frozen faces” from Botox to the “Liquid surgery” And luxury invisible treatments, while the rest of society consumes supplements, Collagen powder and Digital filters as affordable substitutes. And perhaps that distance reveals something deeper: our obsession with shortcuts against the inevitable. The eternal youth industry blooms because we live terrified at the passage of time, as if aging were a failure that must be corrected. But old age is not an anomaly: it is the only certainty we share. Perhaps the real question is not how to avoid it, but why it costs us so much to accept it. Meanwhile, science continues to remember what it works –move, sleep well, Eat better– Although it never sounds as glamorous as a molecule that promises to stop the clock.

Our body is full of almost indestructible “eternal chemicals.” It turns out that we have the solution in the intestine

“Eternal chemicals” is a name with great loudness. They are practically indestructible molecules, and the problem is that they are really harmful for both nature and us. In recent years we are taking it seriously and we have sought Remove them with guns with electron beams. Also through forms of break their molecular bondsand now a bacterium can become an ally to end these eternal chemicals. And it will be as easy as taking a capsule. A slow poison. The perfluoroalquiladas and the polyfluoroalquiladas, known as PFASThey are a relative of about 4,700 synthetic molecules that have great resistance due to the unions between fluorine and carbon atoms. They are very useful for that resistance, since the molecular union is very stable and does not react to external agents. The problem is that they are used in many products (hygiene, textiles, pesticides, containers or Even in the wine), they accumulate in nature by not being destroyed and, potentially, also in our body. PFAS and their derivatives, such as trifluoacetic acid, are related to soil contamination and water sources. And the prolonged exposure to certain PFAS has been related With a higher risk of kidney cancer and testicles, alterations in the immune system, changes in cholesterol, fertility problems and increased blood pressure in pregnancy. Intestinal bacteria. That is why we commented on some lines: we are looking for how to end them. It is difficult, but researchers from the University of Cambridge have TOP With an unexpected ally: human intestinal bacteria. Specifically, the Faecalibacterium prausnitziian intestinal bacterium that, together with others found in our body, has proven to be very effective absorbing pfas. In experiments, and as they point out in Natureresearchers have found about 38 bacterial strains that absorb these eternal chemicals. Basically, they quickly accumulate great concentrations of PFAS minutes after exposure to them. How do they do it? Catching toxic compounds within cell groups, protecting both themselves and the host. Come on, putting the pfa in quarantine. Swallowing more and more. To test it, the toxicology unit of the University of Cambridge experienced with mice that had ingested PFAS. They introduced nine bacterial strains in their organism and observed that these bacteria quickly trapped the PFAS and then were naturally expelled through the feces. The interesting thing is that bacteria work more intensely at greater concentration, with constant elimination rates of between 25% and 74% of the PFAS present in the body. Horizon. Studies are constantly published in which they tell us how they have discovered the potential of something to improve our life, but usually, the conclusion is usually a “we need more evidence and we will see.” In the case of bacteria that engulf eternal chemicals, researchers have something clearer what the road map is after those first experiments in mice. In the next steps, they will explore the development of Probiotics specifically aimed at improving our defenses against PFAS, and they have it so clear that they have founded a startup of biotechnology To develop these products. The objective is that the first is ready by 2026 and what these specialized probiotics will do will be to capture chemicals before they are reabsorbed in the intestine and “encapsulate them” for excretion through the digestive system.

If China invades you will be an eternal conflict

Just a month ago a kind of Leave Vú On the island of Taiwan: it had dawned with a Fleet from China in front of its coasts, again. Beijing repeated the strategy once again, and the enclave then made a decision: Activate a plan B Making the greatest simulation of its history, an invasion disguised as maneuver that lasted 14 days to see how far their defenses would go. The island has now decided to adopt another strategy by looking at Ukraine. Survival and resistance. I told this week in Exclusive the Wall Street Journal. The Taiwan government has initiated an urgent and deep transformation of its armed forces in the face of the growing concern that China can launch an invasion before 2027. The main change in the strategy lies in the fact that the objective is not to defeat Beijing in a direct confrontation, but to resist sufficient time to intervene, for example, the United States. PUELCOESPIN. To do this, Taipéi leaves his traditional preparation for conventional war and adopts An asymmetric strategy Known, according to the newspaper, as a “porcupine strategy”, designed to inflict such a high cost to the invader that a attack dissucted or at least stops it. This involves deploying multiple coastal layers, reorienting its navy towards coastal operations, reorganizing its army, increasing its anti -men and anti -aircraft missile arsenals and multiplying the acquisition of drones, with the intention of Replicate the Ukrainian model in front of Russia. Plus: has founded a Specialized Academy in training with drones and modernized the formation of their troops to operate sophisticated weapons systems in real combat conditions. Inspiration in Ukraine. As we said, the example of Ukraine has served Taiwan to learn fundamental lessons, such as the speed with which ammunition reserves are exhausted in a prolonged war. However, the insular geography of the enclave would make extremely difficult to receive external supplies in case of blocking. Therefore, their authorities insist that Increase missile reserves It is a priority. This change of doctrine, however, faces other obstacles. The Minister of Defense, Wellington Koo (one of the few civilians to hold the position), must break a military mentality centered for decades in the conventional war. There is more, since it adds Trump’s pressurewhich has required Taiwan to raise his military spending until 10% of GDPa difficult goal to achieve for a country that for years has maintained spending around 2%. President Lai Ching-you has committed to increase it to 3% Before the end of the year, although it faces a parliamentary opposition that prefers a more conciliatory policy with Beijing. Finally, there is a political paradox: the small and cheap weapons typical of an asymmetric war (such as drones and missiles portable) are less visible as Commitment sample Budget, despite its greatest efficiency. The “military” vs. society. He WSJ added Another “but” very important to the new strategy. Beyond the doctrine and weapons, the biggest Achilles heel of the Taiwanese defense is its personnel scarcity. With a goal of 215,000 troops, the army had only covered 78% of its places At the end of last year. Demography It does not help: Taiwan has one of the lowest birth rates in the world, and its youth (educated in decades of economic growth and pacification) shows little interest in the military career. The “mili.” The authorities have extended the mandatory service four to twelve monthssalaries have risen up to $ 400 a month and have modernized military accommodations. At the same time, recruitment campaigns that appeal to patriotism and youth idealism have been launched. It is also reversing to improve the mobilization of reserves, a key component to face a prolonged conflict. The formation of the conscripts has changed radically: now Soldiers are trained In the use of drones, Stinger missiles and defense maneuvers in realistic scenarios, abandoning the old training routine in contact without contact with advanced armament. The importance of the strategic alliance. Although the Taiwanese plan presupposes that the United States will go to its defense, that support is not insured. After seeing how Trump reduced the support to Ukraine, Taipéi seeks convince Washington that your defensive effort justifies an eventual intervention. Bilateral military cooperation is still under development and, According to analystsa lot is missing for both forces to execute real joint operations. Hence the agreement that We count a few months ago And that Taiwanese officials admit that they have no experience in modern war and need to learn from those who do, that is, from American army. However, the Pentagon has not made public comments on the degree of joint preparation. In that sense, the island seeks not only to equip yourself, but also coordinate doctrinal and operationally With Washington, aware that his survival could depend on both his own advances and on the political will of the United States to intervene the time. Between urgency and reality. In short, the success or failure of the new Taiwanese defense strategy will depend not only on available time and military muscle, but also on internal support and political will both local and foreign. Taiwan is trying to reinvent its defensive capacity with unprecedented speed, in a context of growing regional pressure, low war experience, demographic challenges and political polarization. Ultimately, its objective is not (it has never been at all) to win a war against China, but to make it expensive enough, slow and painful so that, in essence, it never begins.

The “eternal chemicals” are already everywhere. And that includes one of our favorite places: Spanish wine

The “eternal chemicals” have become a hot issue. These chemicals are widely used in a variety of contexts but their increasingly common presence in the environment worries both environmentalists and the health sector. And for now we know little about the possible impact of these substances on the health of people and in ecosystems. “Eternal” chemicals in wine. A study by the environmental association European bread(PHASE Action Network Europe) He has warned of the presence in the European wine of one of the substances we usually refer to as “eternal chemicals”: trifluoroacetic acid. PFAS and TFA. PFAS are the acronym with which we often refer to the category of perfluoroalized and polyfluoralized substances. It is a family of synthetic molecules (there are about 4,700 compounds of this type) that stand out for resistance that imbues the union between fluorine and carbon atoms. These compounds They are useful For example, in the manufacture of non -stick objects, but they can also be found in pesticides, containers or hygiene products. This is a molecular union Extremely stabledoes not react to external agents so it is extremely difficult to make these substances decompose, either by natural processes or otherwise. That is why these substances tend to accumulate in nature and, potentially, in our body. Interestingly, one of the problems with these substances is in one of the products as a result of the decomposition of the PFAS, the trifluoroacetic acid (TFA). This is precisely the “eternal chemist” on which the new study has focused. 49 wines. The analysis It began with a dozen Austrian wines of relatively old vintages and was expanding to include more recent crops and other countries. In total, 49 wines were analyzed, including at least one produced in Spain. They observed that wines prior to 1988 They did not contain traces of TFAbut that from that year the concentrations were increasing, first little by little and, as of 2010, significantly. The average concentrations in the vines of vintages between 2021 and 2024 was 122 µg/l, although peaks of up to 300 µg/l were detected. Although the phenomenon extended throughout Europe, the team indicated that Austrian wines were the most affected. Other Detail highlighted By the association it was the correlation between the concentrations of TFA and waste of synthetic pesticides. Ecological production The study of European bread He noted that ecological production wines also did not get rid of the presence of these substances, although it is true that they showed some concentrations less than those found in other wines. To what extent are a risk? Today we do not know for sure the effects of “eternal chemicals” on our health, but there are some indications that allow us to get an idea of ​​these possible effects. TFA has been linked, for example, problems for Fertility; But other compounds of this family have also been related to immune problems and even a greater risk of cancer.

Genetics offers some clue to answer the eternal question: What the hell goes through my cat’s head?

Who has lived with a cat has probably intrigued more than once by the sometimes incomprehensible Gatuna Psychology. Now, a project seeks to respond to some of the mysteries that surround the behavior of these felines in the hope that their psychology is not, after all, completely impossible to understand. Cats are sought. And the first step to achieve this is in Create a database with information about numerous cats of various races and contexts. It is precisely what the Darwin cat initiative team is doing, or Darwin’s Cats. Plans. He objective of this project It is to collect 100,000 cats enrolled in June 2026, although they have not yet reached the 10,000 mark. The team seeks to gather information on the behavior of felines through a questionnaire and information about the genetics of each individual. For the latter, participants will have to send a hair sample from the animal next to the questionnaire. Combining these data, the team hopes to obtain the highest database of its kind to investigate not only in the behavior of these domesticated animals, but also expand our knowledge about their health. Who wants to register your pet, yes, you must pay a donation of about $ 150, in order to finance the investigation. In Xataka Communicating with our cats has always been a complex task. A study has discovered the key: flashing Darwin’s ark. This project is not the first in its style for the team that undertakes it. The initiative is part of the work of the Darwin Ark Association (Darwin’s Ark), which a few years ago made Similar work With dogs. Behind the project There is a team of researchers linked to the Chan School of Medicine of the University of Massachusetts and Broad Institute. Inquiring in feline psychology. Perhaps because of the contrast between dogs and cats or perhaps because their behavior really is strange to us, the psychology of cats has intrigued many throughout the long history of coexistence between felines and humans. So strange is sometimes the behavior of these animals that we have come to apply evidence aimed at detecting psychopathy trends in these animals. In recent years, this field of study has put some emphasis In the genetics of cats when confirming some ideas about the existence of hereditary features in the personality of these animals. A quite widespread notion but that we are still understanding. {“Videid”: “x95dxwi”, “Autoplay”: fals, “Title”: “The strongest animal measures 1mm so are the most fearsome animals”, “Tag”: “Webedia-prod”, “Duration”: “343”} Health issue Understanding the genetics of these mammals goes beyond finding patterns in their behavior. It can also help us when detecting genetic components of some of the diseases that affect cats and thus be able to find ways to improve veterinary attention to these animals. Perhaps they can even help us prevent or cure some of the diseases and disorders that affect very present animals in our environment.

China became famous for its eternal working days. The solution has been to throw employees at their time

The Reduction of the working day It seems to be a path of no return that many countries have proposed to move. Some, Like GreeceThey do not do it with a determined step. Instead, others whose self -denial It seemed immovable, they are surprising the world with day reduction measures. China is one of those countries that, unexpectedly, has proposed to cut its workday. Labor culture 996. While in a large part of the West the eight -hour workday begins to be seen as a vestige of the last century and fights for the reduction of working hours, in China the culture 996 still continues: work from nine in the morning to nine o’clock at night and six days per week. Such and as they tell In ethic, that pace of work is taking Chinese society to the extreme, pulling on the soils The birth rate in a country that for years has sinned just the opposite. Chinese authorities have been trying for years Eliminate the culture of 996 of the workplace, but Without too much success. Dji has seriously proposed. According to The published by SCMP, Since the end of February something very curious is happening in DJI, the Chinese drone manufacturer. When the clock marks nine o’clock at night, a squad of human resources managers travels through the brand’s central offices in Shenzhen. Their mission is to make sure that all employees without exception leave their jobs and go home as if it were a fire drill. Instead of evacuating the building for security, employees are “guests” to leave their cubicles to meet a new rule: no one can work beyond their day. The fault is “Neijuan”. No, Neijuan It is not the name of the company’s Human Resources Manager. The term could translate to something as “involution” and, as they explain in SCMP, It refers to the need to reduce excess competition in certain areas of the economy. The measure is imposed as a New economic policy of China in which it is intended to reduce the excess of competence that makes companies in certain sectors such as The technological either Renewable energiesinvest an unnecessary amount of resources without obtaining an improvement in their profitability or in their R&D in return. Therefore, it implies outbound templates without registering a significant advance generating inefficient competition. It is something unpublished in China. Until recently, it was common to see the offices of DJI illuminated until the early hours of the morning with employees who lengthened their days until infinity. Now, the image is very different and has impacted many who have commented on social networks. The Asian media highlighted the publication of a worker surprised by the measure that commented “it was the first time they threw me from the office.” Other technological giants are adding. Although the work culture 996 has the support of prominent names of the Chinese technology industry Like Jack Mamore and more international companies such as Haier or Measure They are adding to the call of the Chinese government of limit the days of its employees. According to sources of SCMPHaier would have ordered all the staff of his headquarters to respect the breaks of two days of the weekend, while Midea has begun to demand that the workers file their departure at 6:20 p.m., instead of 9 pm.
