In the war cameras vs lidar, Tesla has a lot to learn from an unexpected product: the Chinese aspiring robot

by

Light detection and ranging. Or, what is the same, detection and measurement of light. These are the words behind Lidar. This technology uses light pulses to map the environment and discover each and every corner of a stay or an open space almost in real time, as well as to recreate 3D environments with enormous precision. To understand how a lidar radar works, I recommend watching Mark Rober’s video in which it tells the differences between a car equipped with this system and its tesla, which exclusively uses cameras to detect the obstacles that you can find along its path. Beyond the controversy arising in relation to the tests that Rober does, the video explains well Why Lidar is such a complete system. In a simple way, the system takes advantage of the speed of light to emit infrared pulses. These bounce in the object in question and the system calculates how far that object is using the time that the pulse of light has taken to go and return. As light pulses have a very small size and, as we said, it takes advantage of that very high speed of light transmission, can map the objects almost in real time. In recent days, after Mark Rober’s video, the controversy of whether it is better to use an LIDAR or one system that exclusively use cameras and recreations by software is better or worse to guarantee the best behavior in terms of autonomous driving. A controversy that has left people trying launch your tesla against a wall With a road painted in the purest shyesty style. And it is a long time since it made it clear that I would bet everything on the use of cameras for manage your driving aid systems Or, in the future, completely autonomous driving with the robotaxis that wants to put in the streets. At the time, home vacuum robots also lived this moment of indecision. And along the way, Irobot who was the leading market leader has ended up giving millionaire losses and has seen how Chinese manufacturers have eaten much of the market. The secret of the latter: they use lidar instead of trusting everything to the cameras. What can you learn from a vacuum cleaner “We have substantial doubts”, with these words Irobot owners responded to the question of whether they could move forward with their operations. My partner Javier Pastor explained A few months ago when Amazon raised the purchase of Irobot in 2022 (which fell into regulatory terms) The company had a value of 1.2 billion dollars. In the third quarter of 2024, the calculation was about 200 million dollars. Shortly after, The situation has not improved a lot. In 2024, Irobot lost more than 145 million dollars. However, they had reduced their losses by 52%. The company faced a perfect storm. After spending the worst of pandemic, spending on home robots and other products (such as computers) They collapsed. That coincided with the launch of new Chinese products that were faster and faster than Irobot’s: they used the lidar sensor. This system is ideal for improving the capacities of a vacuum robot. It detects better obstacles, mapping the house more precisely and that translates into faster and more effective work. The result is especially good if it is combined with the cameras and artificial intelligence systems to discover smaller obstacles that can go unnoticed or create confusion. In recent years, that has been the trend of the market in cleaning the home. The combination of this system with a more attractive price He has triggered the sales of Chinese aspiring robots, to the detriment of an Irobot that accumulated more than 60% market share. The comparison with Tesla and the electricity car market is evident. The latter are using Lidar sensors in their cars and offer a product equal to or better than Europeans and Elon Musk’s for a fraction of their price. He Xiaomi Su7 and its wide reception He is being a good example of this. Tesla has long since defends that Lidar are not necessary to improve autonomous driving systems but studies say that, as in the case of vacuum robots, the best performance is signed When both technologies are combinedLidar and cameras. In the case of Xiaomi, the videos shown from How your total autonomous driving system operates They are impressive, with very human behavior and managing the smallest spaces very well. This is possible because, among other things, A lidar is better when calculating distances And suffer less when the light falls. Neither does the risk of the camera be dazzled, At least not intentionallygenerating Ghostly brakes. So far, everything indicates that Tesla does not seem willing to return to anything other than the “All Chamber” To save costs. At the moment it has worked but you have to demonstrate that it is as effective as more advanced systems. And there is also the largest electric car market in the world. In China, where foreigners are suffering from the local product, Tesla is hitting a good batacazo in 2025.

16 Functions and tricks of the blue circle with the artificial intelligence chat

by

We bring you a list with The best functions and some tricks of Goal AIthe artificial intelligence that has been integrated into WhatsApp with A blue circle. It is something similar to having Chatgpt in WhatsAppbut in this case it is the AI ​​created directly by those responsible for the app. The idea of ​​integrating goal AI in the application is that you always have at hand the possibility of chatting with artificial intelligence and asking for anything without having to open any app. Now we will tell you some of the things you can ask to give you some ideas. And as we always say in Xataka Basics, we invite you that if you think we have left an important function tell us in the comments section. Thus, all Xataka readers can benefit from the knowledge of our xatakers. Get out messages like templates Have you been late for an appointment? Do you want to congratulate a birthday? Doesn’t it come in any ingenious to write? So goal ai can do it for you. You just have to ask for something like “write a message of ..” specifying what you want, and will do it for you with one or two examples. Here, what will generate goal AI is a template to which you then have to add names and others. You can also Specify the context of the message you want to write, or even the tone you want to use to make the result as well as possible. Check your messages before sending them But imagine that you want something more personal, such as writing your own long message to talk about an important topic. However, you are not sure that you have written it correctly. In that case, you can ask goal to Check the spelling and grammar From your message. Thus you can make sure you do not have any important error, especially in those cases in which the message is serious or professional and you want to make sure it causes a good impression. You can ask general questions As with any other artificial intelligence chat, a goal you will be able to ask that Information about whatever you want. You can ask you about things, sites, history, people, whatever you want, and the AI ​​will answer you with the information you have available. This information can be removed from the knowledge base with which AI has been entered and internet. In the event that the information is found on the network, Meta will add the link of the page that it has used as a source. Ask for specific information In addition to general information, you can also Ask for specific information On topics such as history, science, technology, art, literature or whatever you want. Again, goal AI will take your knowledge of your training or internet to answer you. Both this function and almost all can be found in other artificial intelligence chatbots, although the advantage of this is not to need to go out of WhatsApp to make the consultation. You can correct the information If you think it has failed in the answer, You can correct AI telling him that he has failed and what was the good answer. Then, the AI ​​will make a double checkeo of the information, and if it had effectively made a mistake will correct it and try that the changes apply for everyone. Ask for definitions of words and concepts You do not need a dictionarybecause if there is an expression, a concept or a word that you do not understand, you can ask goal to explain it to you. You can ask for any definition and will answer you in an understandable way. Translate texts into several languages Goal AI can also act as a translator. This works in the two directions, you can put a text in another language and ask you to translate it in Spanish or vice versa, write in Spanish and ask that you translate that to English, French, German, Italian, Portuguese and more. These translations can be of any length. It is best to ask you in the Prompt that you make a translation of what you will write below, put two points and then paste or write the text you want. It may be all you want. Ask for entertainment recommendations Don’t you know what to see, read or listen? You can ask goal to I recommend films, series, books or music Based on your tastes. You can ask, for example, on recommendations of a specific genre or also add publication dates. You can also ask for recommendations similar to another specific title, or ask you to make recommendations if you like certain different titles for AI to establish a relationship between them and look for related content. Synopsis of films and event information And if with the recommendations of the previous point you do not finish trusting, you can also ask for A synopsis of a movie or series. You can ask you to explain what something that has recommended you, or directly ask you about a specific title you have in mind. In addition to this, you can also ask for Information about events and festivalsto look for the most recent on the Internet about some that you are interested in attending. Ask him to make games for you Like other AI attendees, goal AI can also make a text -based game. For example, you can ask you Make you a game of guessing words or a trivialand the AI ​​will ask you the questions to wait for your answers. You can also ask for clues. When configuring the games, be sure to tell you that it is the one that makes you play. You will also be able Ask to be a thematic gamelike a trivial based on a fantastic series or universe that you like. It can be your calculator Another possibilities offered by this AI is to be able make mathematical … Read more

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

by

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.

In full birth crisis, in the US there is a movement that aspires to turn its demography: pronatalism

by

“I want more babies in the United States.” The phrase It’s JD Vance and matters especially for two reasons. The first, because although the Republican had shown before His obsession with birth rates, that specific comment released it in January, during His first public speech as vice president of the country. The second reason is that when Vance pronounced it, he did more than give his personal opinion: he connected with a movement that, although not new, seems to be gaining weight (and visibility) in Trump’s US: Pronatalism. And Vance is not the only media figure (not even in the Trump administration) in tune in with a speech that goes beyond the US and It arrives in Spain. What is pronatalism? Roughly, Pronatalism It is an ideology that advocates Increased birth rate of a country. This is defined by the Cambridge Dictionarywhich affects that its basic objective is to increase the population without having to rely on the arrival of immigrants. That, of course, is the definition with thick stroke. If we go down to detail, many more nuances and a mixture of ideologies that do not always coincide in the background or forms are appreciated. “It can be motivated by cultural, religious, geopolitical or economic imperatives,” comments on The conversation Céline Delacroix, professor at the University of Ottawa, adds: its policies “can manifest in various ways, covering from soft measures, such as stigmatizing those who decide not to have children, other hard, including restricting access to contraceptives.” An objective, several reasons While the pronatalist goal is clear, the argument that accompanies it (and justifies) is not always so much. Under his broad and diffuse umbrella conservatives are grouped with religious motivations that see a social pillar in the family, but also more coincident with Musk. In his case the key is not so much religious as the Fear of demographic collapse and its consequences at a social and economic level. The option to open the doors to migration It would be discarded For them for their fear that It ends up weakening The culture of the country that receives it. Perhaps the best known example of that last profile is the marriage formed by Simone and Malcolm Collinsthe drivers of the organization Pronatalist. Although neither of them arrives at 40, the couple already expects His fifth child and aspires to have at least two more. However, the most striking of their case is not the figures, but it is the ideology that has led them to embrace pronatalism. The Collins They are defined as Tecnopuritanosatheists, anti racist, defenders of LGBTQ+ rights and its vision of pronatalism contemplates the use of in vitro fertilization or genetic selection. Moreover, they themselves They have resorted to both, including the Preimplantational genetic test (PGT) to rule out embryos at risk of cancer or “mental health problems” for which there is no quality treatment. “” We obviously analyze the intellectual coefficient, “they add. Is it something new? No. Natalism or pronatalism exists For several decadesbut in the US it has gained remarkable visibility for several reasons, beyond the expectation that can awaken cases such as collins marriage. One of those reasons, fundamental to understanding its boom, is the Birth decline of the US. The other is the notoriety of certain figures in tune with the main objective of the natives: encourage the birth rate of the country. Vance is one of them. Another is Musk, who has At least 11 offspring and In 2022 came to tweet that “the collapse of the birth rate is, by far, The greatest threat that faces civilization. “Donald Trump himself He has recognized openly that he wants to boost a new “baby boom” in the US. The most revealing movement however has made another high position of Washington, the Secretary of Transportation, Sean Duffy. Father of nine children, Duffy has gone from rhetoric to the facts when signing A memo which prioritizes projects aimed at communities with high marriage and birth rates. There are those He has interpreted it as a clear example of “pronatalist policy.” The decision of the Transport Department is interesting because, no matter how much Trump pursues a new baby boom or vance you share your desire to see more American babies, there is an issue that is still pending: How to achieve it? After all, the US is not the first country that intends to increase its birth rate and many others, such as Japan, China either South KoreaThey have proven how complicated it results. The jump from theory to facts is also relevant to the natives because it transparent their internal tensions and differences. The magazine The Atlantic reflects it well in An article entitled “The loneliness of the conservative pronatalist”. To encourage birth, there are conservative cutting formulas, such as promoting family values; But also other liberals, such as granting more subsidies to parents or betting on housing promotion policies, a solution that clashes a priori with the efforts of Donald Trump (and Musk) to achieve On the contrary: put the scissors in the administration. Another friction point is what the Collins represent: the use of in vitro fertilization and other practices that arouse misgivings among anti -abortion. The connection with Europe (and Spain) Pronatalism has supporters, but also detractors. And there are a few reasons that explain it. Although people like Collins try to mark distances with racism, even It is not so much The most active pronatals in the US were the white nationalists concerned that other communities surpass them in number. His recent boom is also closely linked to the speeches of figures on the right, such as Elon Musk or JD Vance, who pronounced his famous “I want more babies” during the Life marchan act against abortion. The result is that extreme right formations have capitalized the speech pronatalist as a reaction to feminism and the defense of sexual autonomy that It has been dominating for years In the public sphere. Also to immigration. Spain leaves … Read more

Transform smartphones sensors into an antimatter chamber

by

One of the reasons why Antimatter is so interesting Not only for particle physicists, but also for the people to whom we are passionate about science, is that the tools we have They still do not allow us to understand what role he played in The origin of the universe. However, the enigma does not end here; Nor do we know what laws govern the faint line that delimits the imbalance between matter and antimatter in the cosmos. Before moving forward, we are worth stopping for a time to briefly review what antimatter is and what makes it so peculiar. Actually, it is nothing more than a form of matter constituted by antiparticles, which are particles with the same mass and spin as the particles with which we are familiar, but with opposite electric charge. In this way the antiparticle of the electron is the positron or antielectron. And the proton antiparticle is the antiproton. The antimatter has a surprising property: when they come into direct contact with the matter, both are annihilated, releasing a large amount of energy in the form of high-energy photons, as well as other possible particle-antiparticle pairs. It is currently being studied in much of the research centers specialized in physics of most important particles in the world in the hope that knowing it better helps us understand some of the mysteries of the cosmos that remain out of our reach. The AEGIS experiment demonstrates how ingenious particles are physicists The sensors of the cameras of our mobile phones are very valuable when it comes to unraveling the mysteries of the antimatter. This a priori statement may seem strange, but it is reliable. And is that a team of researchers from the Technical University of Munich (Germany) who works side by side with scientists from the Cern (European Organization for Nuclear Research) has designed an experiment that, precisely, resorts to this strategy. It’s called aegis (Antimatter Experiment: Gravity, Interferometry, Spectroscopy or ‘Antimatter experiment: gravity, interferometry, spectroscopy’) and is extraordinarily ingenious. AEGIS uses modified sensors of mobile phone photo camera to identify the points where antimatter and matter are annihilated In the cover photography of this article we can see what the device they have built. Broadly the purpose of this experiment is to study the interaction between gravity and antihydrogen, which is a form of antimatter, to verify if the latter behaves before gravity in the same way as ordinary matter. As we can deduce from its name, it resorts to interferometry and spectroscopy techniques to carry out its objective, but the most surprising thing is that the detector uses modified sensors of camera photo cameras to identify in real time the points in which the antimatter and the subject are annihilated. “For AEGIS to work properly we need a detector with an incredibly high spatial resolution. And the smartphones camera sensors have pixels of less than 1 micrometer,” Francesco Guatieri explainedmain investigator of the experiment. “We have integrated 60 camera sensors in our detector, which allows you to reach a resolution of 3,840 megapixels, the largest amount of pixels of any image detector to date.” It is spectacular. Let us trust that Aegis fulfills its mission and these scientists manage to understand a little better how the interaction between antimatter and gravity is.

Coffee has no cholesterol but does raise its levels. And someone has discovered the perfect elaboration to limit it

by

We are increasingly clear that coffee is a food with Positive properties for our health. However, it has traditionally been surrounded by many myths. Many of them Caffeine relatedbut also some related to things as serious as supposed damage to the heart and its incidence in cholesterol levels. And the latter is half myth. Because coffee has no cholesterol, but compounds that, depending on how we prepare it, will influence more or less on LDL (“bad cholesterol”). Cafestol and Kahweol. Let’s see, if coffee has no cholesterol, how do some of its compounds do have an impact on cholesterol? The reason is that we do not drink coffee in grain, but we crush it to get a ‘dust’ from which to get an extraction and, therefore, the coffee cup. When we break down the coffee beans the oils of it are released, and in them we have fat -soluble diterpenes that are those that have an impact on blood cholesterol levels. Mixed effects. These compounds have some health benefits, since they have anti -inflammatory and anticancer properties. It has also been observed that it favors osteoblastic activity that helps bone health and can have antidiabetic effects. However, the contradictions are there. Although both have a similar effect, it is cafestol that acts as an enemy of FXR receptors, inhibiting the synthesis of bile acids in the liver and, therefore, reducing its effectiveness by eliminating the cholesterol from our body. When this occurs, cholesterol levels increase, with more notable increases in LDL cholesterol. The investigation. Does this mean that I must stop drinking coffee? Not much less, since although these diterpenes can influence cholesterol levels, lead It allows to maintain the cholesterol at bay. We are not talking about sugary drinks or alcohol, go. Now, in a investigation carried out by the University of Uppsala in collaboration with the Technological University of Chalmers have found the coffee preparation method that less Cafestol and Kahweol allows our body to reach. Processing. To do this, the team took two coffee samples from different offices resting machine machines every two or three weeks, with coffee varieties that included average and dark gall of five trademarks of ground coffee. Most machines use ground coffee, but a couple They grind before (the super -automatic). In total, eleven machines were analyzed, three that use coffee concentrate (mix with water). Compared the results with other preparation methods such as percolation, the French press, boiled coffee and samples of espresso. The goal is to see which one prepares coffee with the highest levels of both coffee and kahweol. And the result is overwhelming. Boiled coffee. In the upper graph we can see the concentration of coffee in the different elaborations and there is a clear winner, as well as an obvious “loser”. Previously, it had indicated that boiled coffee was the highest source of these diterpenes and was not as recommended on a regular basis. And it is logical because it does not filter coffee at all. On the contrary, the best elaboration to reduce coffee to the minimum possible is through filter coffee. Here there are variations depending on the filter material, but in the analyzes it is shown as the elaboration that, in a more consistent way, keeps the coffee levels in coffee. Interestingly, we can achieve the same effect by preparing boiled coffee if we like it more and then filtering it, which is the icon of the chart sock. Too many variables. A problem that researchers were found is that, although the concentrations of diterpenes in the machine of the machines was always inferior to the preparations of boiled coffee and other elaborations such as French pressthe concentrations vary significantly between machines and between the sampling intervals. Of the machines, those that use liquid concentrated coffee have lower levels of diterpenes, similar to those of the filtered coffee. Typologies. This may be due to the type of coffee that is placed in the machine or the temperature at which they heat the water, but there is a more disconcerting case: that of the espresso. The researchers comment that a “considerable and clear explanation variation is observed in the concentration of diterpenes among the four samples analyzed”, recognizing that it is something that requires an additional study because it could be relevant to the usual consumers of this preparation. “It can contain high levels of substances that raise cholesterol.” It is the warning of this machine in a Swedish office photographed by Uppsala University And limitations. The team has focused on measuring the concentration of diterpenes, ensuring that it is known that they negatively affect other lipoproteins such as triglycerides, but that it is an aspect that they have not taken into account for their research. In addition, they also recognize that, although the results are solid and there is a “better way to prepare coffee” to maximize coffee, the study has important limitations. On the one hand, the size of the sample, since these are several collection maintained over time, yes, but of eleven concrete machines when there are many, many more in the market. On the other hand, there are variables such as water pressure and temperature, contact time between ground coffee and hot water, grinding or grain gall. Next steps. Come on, too many things, something logical taking into account that there are not only many different coffee machines, but a huge fan in terms of water and coffee gut. It is something that, they point out, it would be interesting to analyze in the future, as well as studies that compare coffee consumers of companies with coffee machines in front of others in which they use paper filtered with paper. In whatever, there are many studies and they themselves comment that “long -term prospective studies on cardiovascular results that could help confirm the causality of the associations” must be carried out between the diterpenes and the increase in LDL cholesterol. At the moment, I will continue to have coffee regularly, but … Read more

25% tariffs on cars are already translated into dismissals and plants at medium gas in Mexico

by

One has a thousand ways of Spanish to search synonyms to talk about threats and continuing notices. That of “the wolf”, the pitcher and the fountain, to pull the rope … It will not be for stories, word games or metaphors. Exactly that is the risk that is run with the tariff war that Donald Trump has opened. Since he arrived at the White House, the new president of the United States does not stop launch threats of new tariffsincendiary messages against their own allies (or those that were considered allies until not so long) and more and more statements in which The same is attacked to Europeans than Mexicans and Canadians. And, along the way … little or nothing applicable. Because although the United States applies since April 2 A 25% tariff on cars that pass through their borders and the pieces that help manufacture them, as well as steel and aluminum (also Keys in the automotive industry). The caraded tariffs to these two neighboring countries They are suspended. On April 2 tariffs have been announced to almost the entire world. They should Enter into force on April 9. Yes, we talk about 20% of tariff to any European product and even the 10% tariff applied to an uninhabited island. Or at least Only inhabited by penguins and seals. But along the way, China has already sent a notice: if the tariffs continue, if there is no possible conversation, They will impose back 34% of tariffs to American products. It is the most forceful response that the United States has received so far. But it is not the only one. Because so much threat has consequences. Canada and Mexico already prove how their automotive industry can go through many problems. Some, in fact, are already specifying. The first consequences Until now, Canada and Mexico had been commercial partners. To the point that the Inflation reduction law promoted by the government of Joe Biden that prioritized tax incentives to companies that produced in the United States also contemplated that part of the production would take these two countries. In either of them it occurs A very high volume vehicular. Except Tesla (produces all its cars there) and Ford (77% of what it produces is manufactured in the United States). The rest import vehicles in a much higher amount. General Motors, for example, produces 30% in Canada and Mexico. Nissan 31% and Toyota 27%. With the aim of counteracting the coup, Canada has announced that it will also impose 25% of tariffs on US cars that do not comply with the T-MEC free trade agreement. Both countries, together with Mexico, had been subject to a reciprocal agreement for 60 years so as not to pay tariffs on the import and export of vehicles and promote a connected automotive industry. To understand to what extent the new relationship is complicated, in BBC They explain with a map the complex process since a piston of an engine is born until it is introduced into the cylinder. On the way, the piece crosses the United States to Canada, from Canada passes to Mexico and from Mexico returns to the United States where, it is finally mounted. Impose round trip tariffs It will make a product that has its consequences on employment and the volume of cars sold. Stellantis is one of the companies that has announced drastic measures. The first, the temporary retirement of 900 employees in the United States. They are people distributed by five floors that will cease their work assembling motor trains and trains for a decrease in production as a cause of tariffs. In addition, another 4,500 employees will be sent home in Ontario (Canada), where their factory will remain closed for two weeks. Mexico does not get rid because its Toluca plant (2,400 employees) will also be closed throughout the month of April. Despite being the least affected (taking into account exclusively the production of cars and not so much where the pieces they use), Jim Farley, CEO of Ford, already warned in February that “a 25% tariff at the borders with Mexico and Canada would open a hole in the US industry as we have never seen,” they collect in The New York Times. These pieces are, without a doubt, the part that most directly affects Spain. Our country had an important commercial partner in the United States when selling parts to produce cars. There 4% of them are exported but, above all, they take air to the paths that the trade war will take in Mexico where a good part of The largest Spanish companies are settled. The other way is to make the products more expensive, move there part of their production or, directly get them out. The latter is what they value in Mercedes that can Stop selling your Mercedes Gla. Small cars are more complicated to make profitable and would not be competitive if they face a 25%tariff. Volkswagen is in an extremely complicated position. 43% of their sales for the United States arrive from Canada and Mexico. Another 36% produce it in Europe, mainly. Only 21% of their sales there are produced within their borders. An option raised is to bring the most profitable vehicles to the plants they already have in the country. For the moment, Automotive News He assures that the German company has already ordered to stop its shipments from Mexico and Europe. And Toyota, who was already reducing its production, has also ordered to reduce the working hours at its Guanajuato (Mexico) plant, they point out in Bloomberg. The same path leads in Honda, where they also have conversations to reduce their production and, therefore, send workers home even if it is temporarily.

We have studied the bones of some mice that passed 37 days in space. The results are not optimistic

by

In November of this year, if there are no unforeseen events, in November of this year humanity will celebrate an anniversary. They will be fulfilled 25 years of human presence continued in space. The exploration of the last border has advanced significantly and humans spend more time in space and aspire to get further. But that has a price. The cost of microgravity. A team of researchers has analyzed The effects of a spatial mission on mice and the results do not invite optimism. They observed that the stay severely affected the bones of these rodents, who lost bone density in parts of their body. The femur, great victim. This loss of bone mass was not given in all areas equally. The team observed, for example, that the femur was one of the bones where the most extended bone cavities. In contrast, the lumbar zone of mammalian spine were the least affected. This makes the study responsible for the study suspect that the main trigger for this loss of bone density is in the microgravity. For example, the team indicates an alternative hypothesis, radiation. As they explain, the mice in the ISS were not exposed to large doses of radiation from space, but if this had been the loss of bone mass would have occurred from outside, that is, that the bones closest to the surface would have been more damaged, while the most surrounded by muscle bones would have been more protected. 37 days in orbit. The experiment used mice to explore how long rooms in space affect. They were used Two groups of micesome that were sent to the space station for a mission of 37 days and others that remained on Earth as a control group. The team responsible for the study simulated flight conditions in the control group to be able to make the conditions similar in everything except in the space stay. Similar, not identical. Those responsible for the study explain in a video how mice and humans keep important biological similarities that imply the changes we see in some are probably also giving in others. There are also differences to consider. For example, the fact that humans are bipeds implies that the bones of our lumbar zone have a more important role in supporting the weight of the upper part of our body. This implies that these bones are probably more affected in humans than in mice. The details of the study were published In an article In the magazine Plos One. If you don’t use it, you lose it. The body often tries to optimize resources. That is why a possible explanation to this phenomenon is there, in the idea that, since the bones in microgravity do not need to endure the weight of our body, they lose mass and density. Other risks. The study points to microgravity as the main suspect of the loss of bone density but this is not the only risk to take into account when we devise long -term space trips. Radiation is perhaps the most important in this sense, to the point that it was considered as a candidate to cause bone mass loss in mice. Radiation implies an additional problem and that, although in places like the moon and Mars the seriousness of the bodies could reduce the deterioration of the bones associated with the microgravity conditions, the same cannot be said of radiation. Moreover, the radiation in these environments is greater since the International Space Station even protected by the Earth’s magnetic shield.

We have been using sweeteners that provide zero calories. Now we understand why they don’t always help lose weight

by

Sugar is one of the most daily foods and one on which food controversies do not scarce. Excessive sugar consumption can be linked to various problems, from the oral to diabetes. The artificial sweeteners that we sometimes use to reduce the consumption of conventional sugars can be healthier, but no less controversial. Less sugar, more hungry. A recent study He has found that some artificial sweeteners could be affecting the signals that manage our appetite at the brain level. The team responsible for the study observed that the Sucralosa had a less satiating effect than sucrose, conventional or table sugar. The Sucralosa. Sucralosa is a artificial sweetenera disaccharide or compound sugar such as the union of two simple sugars. Its sweetest capacity is up to 600 times higher than that of sucrose, but our body does not absorb it in the same way. This implies that this sweetener has no caloric contribution to our body. This could explain the observed phenomenon: our body would perceive the sweet taste and prepare for calorie ingestion. The body would simply be responding to the absence of energy received. 75 participants. In the study, 75 participants who worked as both of the experimental group and control group in two sessions separate days or weeks from each other took part. Participants, men and women, some with “healthy” weight, others overweight or obesity, consumed three drinks prepared in the experimental sessions to which they underwent. These preparations were a sweetened drink with sucralose, another with conventional sugar (sucrose), and another simple water. The order in which they assigned each drink was random. The team later studied the participants’ response to each drink. Before and after the test they carried out functional magnetic resonances, they took blood samples and asked the participants for their feeling of hunger. They observed that the sucralose increased appetite and activity in the hypothalamus and that it did it to a greater extent among the participants with obesity. The team also detected changes in how the hypothalamus communicated with other brain regions. The details of the study were published In an article In the magazine Nature Metabolism. Old acquaintances. The key can be in the hormones that our body produces when eating, hormones such as insulin and LPG-1 (Glucagon -like peptide 1). This last hormone is produced in the stomach when we eat and fulfills a double function: on the one hand warns the pancreas that we will need insulin to manage digerida glucose; and by transmits to our brain the message that we have fed and satiated. “The body uses these hormones to tell the brain that you have consumed calories, to reduce hunger,” Explain in a press release Kathleen Alanna Page, co -author of the study. “The Sucralosa did not have that effect, and the differences in hormonal responses to the sugar compared to sugar were even more pronounced in participants with obesity.” Much to investigate. According to the team itself, there are still some unknowns to solve in this context. One question, for example, is how this sweetener affects our brain activity in the long term. To do this, they explain, longitudinal studies will be necessary that also analyze the weight and food behaviors of the patients. Another issue to solve is how other factors affect, such as sex, this relationship. The team indicated that during the experiment, the brain activity of women showed greater variability than that of men, which implies the possibility of differences to study.
