All this and more in 1×17 crossover

by

Last year the Galician hacker Antonio Fernandes He had a moment “hold me the cubata” with another hacker: both tried and managed to sneak into NASA. They did it ethically, and the curious thing is that the space agency ended up sending a letter of appreciation for explaining how to protect themselves from future similar cyberbrains. That story is an integral part of 1×17 crossoverthe new installment of our technology and entertainment program. But it is also this expert He told us about the practice of Bounty Bug -try hunt failures and vulnerabilities In computer systems – and revealed a fact of the most curious: there is a “Spanish team” focused on this discipline … that won a hacking World Cup! Fernandes also had time to explain in detail how to avoid ransomware attacks, what kind of security we can expect from our mobiles or how dangerous is the future we face now that the deefakes and the malicious AI come to us. Presented by Jaume Lahoz and Carlos Santa Engracia, in this new episode there are also other prominent spaces. Thus, we tried the new Polestar 3the electric SUV that wants to compete (among others) with the Tesla. We play “reality or myth?” With Ana Boria and we even have time to talk about those activity bracelets developed by Whoop that go one step further in the management of physical activity data.

The commercial war between China and the US also goes from airplanes. The c919 comac already threatens the future of Boeing and Airbus

by

The aeronautical sector has become another battlefield of commercial tension between Washington and Beijing. The C919the first narrow fuselage commercial plane developed completely in China, He is winning traction In Southeast Asia while Boeing and Airbus fight against delays in their deliveries. An opportunity born from despair. Malaysia has confirmed that Airsia and Air Borneo are valuing C919 as an alternative to Western manufacturers. It is no accident: the waiting lists to receive Boeing and Airbus airplanes extend years, and the airlines They desperately seek to diversify their suppliers. Malay Transport Minister Anthony Loke summarized it thus: “All airlines look for faster deliveries and cheaper options. COMAC is one of the manufacturers they are considering.” The Chinese pride Achilles heel. Despite its ambition, the C919 drags a critical dependence on US components that could be lethal. LEAP-1C engines (Manufactured by the Joint Venture between GE and Safran), Honeywell’s navigation systems, the rockwell collins meteorological radar and multiple critical components come from the United States. Tariffs and prohibitions. The Tariff climb It has raised the cost of the US components until they make them almost unfeasible. Just a couple of months ago, China applied tariffs up to 145% in response to tariffs applied by Trump, shortly before The 90 -day truce that both countries occurred. At the same time, Beijing has prohibited its airlines from acquiring US suppliers equipment, although this restriction does not yet affect manufacturers as Comac. The race against time towards autonomy. China has not been still in this critical situation. And it develops the engine CJ-1000A through AECC as the National Substitute for Western LEAP-1C. The evidence has been advanced since 2018, although the commercial certification will not arrive before 2030, and in the worst scenario it would be delayed until 2035. Meanwhile, the Chinese domestic market offers an extraordinary mattress: Boeing estimates that China will need 8,600 new airplanes commercials in the next two decades. And now what. The United States has recently reactivated licenses to sell engines to C919, but this movement can also mean China’s reinforcement to achieve technological autonomy in the sector. The European C919 certification could arrive between 2028 and 2031which would open the doors to the global market. If China manages to combine a competitive plane with aggressive prices and fast deliveries, the historical Boeing-Airbus duopoly could have its days counted.

He left his tesla Cybertruck plugged in and went on vacation. Two weeks later, the vehicle no longer lit

by

Imagine the scene. You have a tesla and you are about to go on vacation. The trip will be by plane, so you face an immediate decision:leave the car plugged in During the two weeks you will be out or wait to connect it when returning? If you follow the manufacturer’s recommendations, the answer is clear: it is best to leave it plugged in. That was exactly what Aj Esguerra did, resident in Arizona. The official advice followed to the letter. But when he returned home after his break, he ran into an unpleasant surprise: his Tesla Cybertruck did not respond. This is what they tell in Motorpasion Mexico. What failed? We go in parts. What happened exactly to cybertruck At first glance, everything seemed in order. As the user explains in a group of Tesla ownersthe charger worked, the car had been left with 79 % battery and the Tesla app showed that the load limit It was set at 80 %. But when returning on vacation, Aj Esguerra encountered the last thing one would expect from a connected vehicle: a completely inert cybertruck. “I need help: we were out two weeks and when returning, the Cybertruck does not turn on at all,” he explained. I couldn’t even open the doors. He restarted the charger – the blue light went to flash in red – and began to consider hypotheses: “I live in Arizona and this week we have had record temperatures. Could the battery have overheated and damaged the battery?” AJ contacted the technical service through the app and, as he said, the answer was immediate. “The Tesla service is on its way. They responded quickly through the application and received a call immediately,” he explained. The technicians managed to access the interior of the vehicle, put it in a provisional way and They transferred to a service center For a more complete diagnosis. There came the final explanation. The problem was not the battery, nor the heat, nor an error when programming the load. The failure was in a key component of the Cybertruck electrical system: the Power conversion system (PCS). According to Esguerra, the technicians ruled out that the breakdown was related to having left the car plugged in. In fact, they reiterated that this is still the recommended practice. The good news: Tesla took over the reparation without any cost for the owner. Thus, the vehicle worked normally. What is the power converter and what does it do As Skill-Lync points outthe SCP plays a fundamental role: it is in charge of managing how electrical energy in the vehicle enters and is distributed. When we connect the car to a power outlet, the SCP transforms that alternating current (CA) in direct current (CC) To load the main, high voltage battery. But he doesn’t stay there. Power conversion system He is also responsible for keeping the car’s auxiliary systems – such as lights, internal electronics or sensors – through a second conversion: high voltage to a lower voltage. It is composed of several key elements: CC-CC converters, filters, electronic controllers and a liquid cooling system to avoid overheating. In the cybertruck is located in the auxiliary compartment Known as the “Ancillary Bay”, which requires the removal of some sheets to access it. The official recommendations Tesla makes it clear in the cybertruck user manual: The most important thing to preserve the high voltage battery is leave the vehicle plugged in When not used. This is literally indicated by the manufacturer, which warns that the car, even off, continues to consume energy progressively. And if the load falls to zero, damage that does not cover the warranty can occur. In addition, Tesla recommends not waiting for the load level to be low to plug the car. In fact, he affirms that the system pays better if it is kept loaded regularly, even if it is not used. And in case of a prolonged trip, it advises to calculate that the vehicle loses around 1 % battery per day, although that figure can vary depending on the temperature or vehicle configuration. The background message is clear: nothing happens to leave it plugged for weeks, provided that everything works correctly. Although, as we have seen in this case, sometimes things do not go as expected. So, is it safe to leave the car plugged for weeks? In theory, yes. It is what Tesla recommends and is what Aj Esguerra did. But the case of his cybertruck shows that, in practice, Other factors can come into play They escape user control. For example, a peak of voltage in the electricity grid, a punctual failure in the charger or overheating due to extreme temperatures can trigger a chain of errors difficult to detect if no one is there to intervene. In the absence of supervision, a minor incident may end up becoming a major problem. Esguerra himself acknowledged that, before leaving, forgot to schedule the load for the freshest hours. The Cybertruck was carrying day, in the middle of heat wave in Arizona, for several days in a row. Although Tesla did not attribute the failure to heat or continuous load, that context helps to understand how certain environmental factors can increase risk, especially in extreme climates. So, leaving the car plugged in is recommended. But it is also to ensure that the charger works correctly, that the environment is safe and that the electrical installation is protected against unforeseen events. In that balance between trust and prevention is where you should really reduce the possibilities of meeting any type of inconvenience.

For some reason, evolution does not stop creating antiques. 12 times different around the world has emerged

by

Like the Chavo del Ocho when he did for the umpteenth time the joke to continue criticizing Professor Jirafales once the others had silenced, nature can have somewhat repetitive scripts. The point is that they work. Trend to eat ants and termites. It doesn’t matter if we are in America, Africa or Asia. Again and again, throughout the history of the earth, different mammalian lineages have reached the same evolutionary conclusion, developing a similar body plan to exploit one of the most abundant banquets on the planet. A recent study Posted in Evolution magazine It reveals that the specialization in eating ants and termites (a feature known as Mirmecophage) has emerged independently at least 12 times different since the extinction of dinosaurs 66 million years ago. Convergent evolution. When we think of an anthill, the iconic elongated snout animal of the Americas comes to mind. But the anthill is not alone. Pangolines and Aardvarks, who inhabit Africa and Asia, are distant relatives who have developed a surprisingly similar tools kit. Adaptations include long and sticky tongues, a reduced or non -existent teeth and powerful front legs armed with claws to dig in insect nests. This phenomenon, in which unrelated species They develop similar features To adapt to similar conditions, it is known as convergent evolution. The same strange design. “The specializations associated with Mirmecophage are among the strangest and most fascinating mammals,” says Laura Wilson, an evolutionary biologist, In Science magazine. “This study illuminates our understanding when, and how many times, these fascinating characteristics evolved and under what conditions.” To reach these conclusions, the also biologist Thomas Vida and his team collected and analyzed data on the diet of almost 4,100 species of mammals, mapping their eating habits in the great evolutionary tree. The resulting model left no doubt: the evolution has taken the path of mirmecophagy over and over again, and has done so in the three large branches of mammals, including marsupials and monretrems, which put eggs. The postdinosaurs world. There are several crustaceans that have evolved towards a body shape similar to that of a crab. This phenomenon has occurred at least five times, but over several hundred million years. Mirmecophagous mammals, on the other hand, have done it 12 times in just 66 million years. “For some reason, things continue to evolve until they become hormigueros,” says the author of the study. Why this rise of ants dining rooms just after the disappearance of dinosaurs? The answer, according to researchers, is in the history of social insects. After the great extinction of the Cretaceous-Paleogen, the ants and the termites experienced a demographic explosion. His presence in the fossil registry shot, and his biomass became an abundant ecological resource. A road without return. The study also reveals another fascinating fact: once a mammalian lineage specializes in eating ants and termites, it seems that there is no turning back. The researchers only found a reversal case: the musarañas elephant of short ears. Their ancestors were probably fed on ants and termites more than 13 million years ago, but today, these southern Africa creatures have a mixed diet that includes other insects and plant matter. This evolutionary dead end is probably due to the stability and abundance of the food source, or the difficulty of recovering the features of a generalist once the body has adapted to such a specific diet. The story, therefore, tells us that while there are ants and termites in abundance, the evolution will continue to threaten more mammals into relentless devouring machines of colonies.

The competition is starting to overcome

Things are not going well for Novo Nordisk, the Danish pharmaceutical Ozempic and Wegovythe popular Drugs to lose weight. The company fell up to 30% in the stock market After presenting (bad) results. In the last year, the shares have fallen double, 60%. Although it will continue to grow, it has trimmed its expectations: from a growth in predicted income between 13% and 21% for annual sales, the company has dropped its fork to 8% and 14%. It is just a consequence of what is already living in several markets. Sorpasso. Novo Nordisk had been in a vulnerable situation, and its stock market value, which came to rise 400% from the pandemic, is reflecting what is already happening in the recipe market: according to the Financial Timesthe IQVIA research company reports that the Danish company has been destroyed in market share in the United States by the pharmaceutical company Eli Lilly, its great rival worldwide. A painful loss in the largest market. With 607,000 weekly recipes, Ozempic has fallen below 622,000 Mounjaro, Lilly’s drug. Ozempic has dropped from 50% of sales for the first time, despite the fact that a judge of the Texas district prohibited the country in the country Marketing of Copies of Novo Nordisk products. For Novo, it means losing the leadership in the market where more semaglutida sells Worldwide: in 2023, 71% of sales arrived from the United States. The news adds to another negative: Wegovy had already been overcome by another proposal by Lilly: Zepbound. It was seen coming: in the United Kingdom, Mounjaro already exceeded Wegovy At the end of the year. The CEO of Chemist4u, an online pharmacy, said that in the last three or four months of 2024, Mounjaro won Wegovy in a 70-30. What are Zepbound and Mounjaro. Zepbound was the second commercial name that Lilly put to the Tirzepatidathe compound with which Lilly threw himself to compete against type 2 diabetes, such as Ozempic. If Novo Nordisk launched Wegovy to focus on weight loss as an alternative for the diabetic ozempic approach using the semaglutida, Lilly did the same with Zepbound with respect to Mounjaro. The FDA approved Zepbound’s medical use at the end of 2023. In Spain, it has not been approved for now, but for a year Pharmacies market Mounjaro under prescription for diabetes and obesity. This is how Novo Nordisk lost his advantage. The arrival of Danish pharmaceutical drugs to the United States was marked by a production that failed to meet the spectacular demand. According to Financial Times, Evan Seigerman, BMO capitalist Markets, prognosis problems had to do with a previous medication from Novo, SaxendaIt was not so successful. The supply problems led to the approved the Sale of Ozempic copies. Although Novo Nordisk managed to increase production by acquiring factories, the under supply gave Lilly time, which Mounjaro launched for diabetes in 2022 and Zepbound in 2023. A matter of marketing. When the huge success of Ozempic began, Novo Nordisk went from being a company focused on the sale of insulin that had to convince doctors through research to have to aim at the weight loss market, a massive market focused on the final consumer, and highly influenced by advertising and celebrities. Novo left the door open to Lilly, and Bernie helped. The marketing of the American pharmaceutical He started selling his online drugs. Being also Aggressive with discounts and several price drops. In this sense, Senator Bernie Sanders also did not help will report price differences of Ozempic in the United States compared to other countries ($ 600 per month for 59 of Germany), claiming that generic versions could be sold for less than $ 100, and accusing Novo of using the US market of “dairy cow“ Lilly tests that show advantage over Novo. According to the study results Surmount-5 Posted by Lilly, at 72 weeks, patients who took Zepbound lost 22.8 kilos in front of 15 kilos of those who took Wegovy. A 20.2% weight loss using the lilly tirzepatida versus 13% of the Semaglutida of Novo. With regard to diabetes, the essay Surpass-3 He showed that Mounjaro produced a reduction in glucosylated hemoglobin (A1C) between 2 and 2.3%, compared to 1.9% of Ozempic. A new (and something frustrated) hope. Novo is developing New Generation Drugswith a drug called to be the successor of Wegovy: Cagrisema. The problem with this drug is that initially, the company announced that it hoped to help patients lose 25% of their weight. The result of his trial provided somewhat minor general figures, With 22.7% loss in 68 weeks. 40.4% of the patients who received the dose of Cagrisema did reach 25% loss in that period, but the market was relentless and fruit of the disappointment between investors.
