An American physicist has found a shortcut to get to Mars in 90 days. It is key to surviving radiation

by

The long flight will be One of the many risks that astronauts who travel to Mars in front. SIX TO NINE MONTHS Broken the safe radiation limit that NASA establishes as acceptable: 600 msv. The problem would be forgotten if you could get to Mars in just 90 days. And you can with current technology, according to recent research. Conventional chemistry, record times. The physicist Jack Kingdon, a researcher at the University of California, has published in the magazine Scientific Reports A proposal that breaks with the provisions of trips to Mars. Normally, a flight to the red planet requires between six and nine months, which raises multitude of challenges for exposure to radiation. With Kingdon’s trajectory, 90 days per path would suffice. The most surprising thing is that their calculations are based on the classic method to optimize interplanetary trajectories (Lambert’s problem) and do not depend on futuristic engines, but on a current chemical rocket: the Spacex starship. Two crew and four loading ships. The proposal is a monumental scale. The mission to Mars would require six ships: two crew and four loads that would travel separately. To put them on the route, they would take about 45 Starship pitches within two to three weeks, a rhythm that, although ambitious, fits with Spacex’s plans to massively climb their operations. A gas station in space. The real logistics challenge would occur in the low terrestrial orbit. There, a starship-cistern fleet (ships dedicated exclusively to transport fuel) would perform a complex dancing of reposses: The two manned starship would need about 15 reposses each to load the 1,500 tons of propellant that will allow them to take the rapid trajectory. The four load starship, aimed at carrying the equipment and supplies, would receive only four reposses each and would be sent to Mars in a slower and lower energy consumption trajectory. The shortcut. Once full of methane and liquid oxygen, the two crew ships would turn on their engines to escape the earth’s orbit. They would cover a high -energy Lambert type trajectory required by an ΔV ≈ 4.6 km/s, which translates into a 90 -day flight time. Just before being captured by the severity of Mars, the ships would make a key ignition to stop, reducing their input speed of about 9.7 km/sa about 6.8 km/s. The Martian atmosphere would be in charge of dissipating the rest of the energy by aerocapture, a maneuver in which the ship “brushes” the atmosphere to stop without spending fuel. Finally, a brief ignition of the engines would allow a propulsive landing on the surface. The study demonstrates that this scheme is mathematically possible for the 2035 launch window, but it depends on Spacex dominating two critical technologies: the cryogenic orbital refueling on a large scale and hyperbolic aerocapture. And the return? An even more complex plan. If the idea is to return, the mission becomes much bold. First, a fuel production plant should be established on Mars (As Sabatier reactors) to manufacture methane and oxygen from CO₂ and the ice of the planet. The return plan implies that the manned ship take off from the surface of Mars and entered orbit. There, the load ships, which arrived previously, would also take off to act as cisterns in the Martian orbit, transferring all the necessary fuel to the manned ship for its 90 -day trip back to the earth. Not everyone shares optimism. The study identifies a viable return window in 2037. However, not everyone shares optimism. The own Paper recognizes that his proposal collides with the vision of agencies such as NASA, which has historically shown preference for nuclear propulsion For fast missions to Mars, a technology that, according to the author of the study, still has a low maturity and great regulatory obstacles. All this, of course, whenever the goal is to return. Recall that Elon Musk’s idea is to send robots first and then volunteers to build a self -sufficient city on the red planet.

This map distributes the “heart” of Europe over the Iberian Peninsula. And reveals the key to the success of the region

by

Maps are useful, fascinating and sometimes almost almost An art form. However, they do not always allow us to understand real dimensions and distances well. Especially when we talk about broad territories. A map published in Urbanity.one (and shared by Madrid projects) With a peculiar approach: its author has taken some of the main cities of Central Europe, the metropolis of the one known as “Blue Banana”and has distributed them on a plane of the Iberian Peninsula respecting The real distances. The result reminds us of two things. The first, the considerable size That has Spain. The second, how close the cities of Central Europe, a crucial factor to understand the history and economic development of the region. As a picture is worth more than a thousand words, at the end of the 1980s the Geographer Roger Brunet decided to invent A visual metaphor to refer to the most populous and urbanized region in Europe. He called her The “Blue Banana”. Maybe it sounds strange, but it makes enough sense when a map is taken. If the cities of the European industrial axis are connected, covering from England to the Netherlands, Belgium, Germany and northern Italy, that is: the drawing of A huge banana Located more or less between Manchester, Munich, Zurich and Rome. How big is that “Banana” imaginary? The first response to mind is obvious: very much, right? In Madrid it projects They have shared However, a map that helps to understand that this abstract axis is actually much smaller than what intuition suggests. At least if we compare it with Spain. The reason is very simple. Its author has selected the metropolis that are distributed by that theoretical axis that structures Europe Central and has arranged them on a map of the Iberian Peninsula respecting the real distances between them. The result It shows that Cambridge would be more or less where Vigo is, Rotterdam would stay up to Valladolid, Bremen in Pamplona, ​​Stuttgart almost where Alicante is and Paris would more or less occupy the place of Badajoz. In the center of the Peninsula, in Madrid, it would be located (kilometer up, kilometer down) Düsseldorf and the Barcelona space would occupy by Linz, an Austrian city. The cast may be striking, but it arrives with pulling Google Maps and its measurement tool for Check the distances. Between London and Paris there are about 340 km in a straight line, just under those that separate Madrid and Granada. If we pull a straight line from Rome to Munich would measure approximately 700 kilometers, a little less than Barcelona to Córdoba. Comparisons are interesting for several reasons. The main one is that they remind us The great size of Spain. The Iberian Peninsula measures just over 583,000 km2 and Spain occupies approximately 505,000taking into account the 12,500 km2 of island surface. That makes our country one of the most extensive of the community club, together with France and Sweden and Germany. A wide disposition of land is both an opportunity and a challenge in aspects as a distribution of the population or provision of services. The other great conclusion left by the map Shared by Madrid projects It is the close thing that are actually the Central European metropolis and their main industrial poles, population centers and strategic axes of political decision -making, a proximity that has influenced the development and integration of Europe.

Even so, he is going better than expected, and the key is in user pocket

by

There are companies that appear everywhere, which have millions of users, which seem unbeatable. But behind that dazzling popular there is a fact that is often overlooked: They are not profitable. Some have been growing at full speed without ever generating benefits. Openai is one of those cases. His name is on everyone’s lips since Chatgpt He went into the world in 2022. But the truth is that, economically, he is still far from quading the accounts. Spend much more than you enter. And it will not be profitable for several years, if they are fulfilled Your own calculations. The paradox of success that does not give benefits OpenAi is everywhere. And chatgpt too. In just over two years it has gone from being a technical rarity to get into mobiles, computers and conversations. But that something sounds a lot It does not mean that it gives money. In fact, the accounts are still in red. Because the phenomenon is real, yes. But so is the expense. Training increasingly large models, keeping servers working and hiring talent is not cheap. According to The InformationOpenai would have lost about 5,000 million dollars in 2024. And this year the thing does not look much better. It is not a unique case. Spotify was founded in 2006 and It took twelve years to see benefits for the first time. Twelve. And only in 2024 managed to close A full year in positive. Have millions of users It does not guarantee May a company be profitable. Openai does not seem to be close to balance, but there is an important difference compared to a year ago. According to Financial Timesyour subscription income has shot. It has gone from generating $ 5.5 billion to approach 10,000. Half of that money comes from users who pay for chatgpt. Telegram’s case also helps put things in perspective. The application was born in 2013 and for more than a decade operated without generating benefits. Only in 2024, after exceeding 900 million users, Finally reached profitability. It took eleven years. Openai aims to follow the same path, but at another pace. The company already has told its investors that does not expect to be profitable before 2029. And for that to happen, it needs a very concrete figure: reach 125,000 million dollars in annual income. The company has already told its investors that it does not expect to be profitable before 2029. It is an ambitious objective, especially if we take into account that today is around 10,000 million. For multiply by more than ten Its turnover, OpenAi not only trusts that more users subscribe to Chatgpt, but that much of their income is related to their API. When we talk about the API we are referring to the system that allows you to integrate OpenAI models into third -party applications. Companies of all kinds, from banking to health, which can use various models of the company, such as GPT-4.1, to improve their benefits. Another important source, According to The Informationthey would be the calls Artificial Intelligence Agentsmore sophisticated tools that not only answer questions, but do complex tasks autonomously. Openai wants this to become its great premium product. It should be noted that many of the great technology (Microsoft, Google, Tesla) quote on the stock market and publish each quarter accounts. That forces to generate official reports, audited data and financial transparency. Things are different in the startup led by Sam Altman. OpenAi does not quote on a stock market and adopts a hybrid model: a non -profit entity (Openai, Inc.) controls a subsidiary with limited profittoday in the process of becoming in a public benefit corporation to capture greater investments than those received. Not being obliged to publicly audit your commercial accounts, OpenAi does not publish official figures. There are no quarterly reports of income, costs or losses. This is usual in many US private companies, which have greater financial confidentiality. Therefore, when we talk about current Openai numbers, we do it supporting ourselves in leaks, in Media estimates such as The Information or in data that the company itself shares selectively with investors. There are no periodic official reports, because they do not exist. There is no doubt that Openai has achieved something huge: he has put generative artificial intelligence in everyone’s mouth. But that does not guarantee income, much less benefits. Touch to wait to know if the company will meet its goals. For now, it seems to be on the right track.

the 15,000 ninja companies that dominate key niches without anyone knowing them

by

China not only manufactures giants such as Alibaba, Tencent or Tiktok. He has built meticulously An army of 14,600 “small giants” that dominate fundamental industrial sectors, but without making noise. Why is it important. While in the West we follow the track of BydXiaomi, Bytedance or Huaweithese specialized SMEs are those that control the pieces of the industrial puzzle. Sensors, aerospace components, specialized semiconductors: the niches where technological supremacy is really won or lost. The context. He “Little Giants” program He was born in 2015 as part of “Made in China 2025“Its objective: push highly specialized medium -sized companies to develop competitive advantages in specific sectors. A surgical model against the model of large state companies. There are 15,000 “small giants” with official certification. Almost 90% are in the manufacturing sector. More than 80% focus on emerging strategic industries such as integrated, robotic or aerospace circuits. And almost 5,000 work in AI AND CLEAN ENERGIES. That is happening. Each “little giant” receives state support to dominate a specific niche. Submarine cables, superconductor materials, quantum sensors, satellite systems … technologies that seem lower but vital for global supply chains. And for Chinese military development. Some examples: Leaderdrive: Specialized in precision harmonic reducing. Endovtec: Develop advanced endovascular devices. Phabuilder: Biotechnology to produce industrial materials. Acoinfo: Develop real -time industrial operating systems. Guizhou Anda: Battery materials, supplies Catl and Byd. WELION: solid state batteries of high energy density. JIASHIDA Robot: Domestic cleaning robots. It is no accident that The United States has already included many of these companies in their blacklist. They are the real threat: not the brands that anyone knows, but those that manufacture the components that make the world work. This “unique champions” strategy makes medium -sized companies practically monopolies into ultra -specialized sectors. Result: If you need a certain type of semiconductor or components, you have no alternative. And that company is subsidized, protected and backed by the Communist Party.

The mobile industry has been desperate for years to improve its cameras. Honor believes having found the key

by

A few weeks ago I had the opportunity to try the Honor 400 Pro. It is a mid-high-end phone with the focus on mobile photography. So far, there is nothing especially surprising. But if I tell you that this phone sets the bases of a Honor who does not believe that the future of photography is in the hardwarebut in cloud computing, things may change. In Xataka we have been able to talk to Luo Wei, Chief Imaging Architect of Honor. He is the one in charge of leading the photography part, applied to it and super zoom in honor, and ex-huawei. And someone who is clear that to win the smartphone career you have to win the AI ​​race. If marketing sounds like you can be calm. It is not, it is the vision of the future of a giant who aspires to conquer Europe. Honor wants to lead in Europe, and wants to do it with ia To understand why AI for honor in phones is so important and not misunderstand it as a marketing exercise, it is necessary to know the relevance that the company has with its Alpha plan. In March 2025, the company revealed a investment of 10,000 million dollars In five years to promote artificial intelligence on their devices and display your first AI agent, in association with Qualcomm and Google. The objective is clear: lead the AI ​​agents in the mobile ecosystem and be the main reference in this race. At the moment, he will do it hand in hand with these two partners in Europe. Honor has different strategies for China and Europe. In our territory, Google Cloud is the main partner It is also relevant to understand that this plan has a lot to do with The position of honor in Europe and how it aspires to conquer our market, more than a proposal centered purely on your native country. With counterpoint data in your hand, Honor is the brand that grows most in shipments in Europe in an interannual wayand wants to continue pushing leading the functions of AI. In China, its AI approach is different, deeper and more local. There the partner is not Google Cloud, they are national giants like Alibaba (Qwen + Wanxiang), Baidu and Tencent Clouddeepening much more in your Yoyo assistant and hand with Depseek. All of AI One of the pillars of this plan, in addition to the creation of the first agriculture for smartphones, is Aimage. Landing the term to the tangible: the high -end phones of honor process the photographs in the cloud to “improve them”. And about this there are many questions. The first is why. Here Luo Wei states that, historically, Mobile photography has been limited by hardware. A limitation that according to Honor can only be overcome using cloud computing, especially for tasks such as image restoration, provide movement (turn into short video) static images or improvements in the zoom. Being more concrete, 12,500 million processable parameters for its cloud model vs. 3,000 million parameters with which current hardware can deal. Adding to this point the possibility that stresses honor of updating its algorithms via Ota. It’s something we have talked about in Xataka: We have been watching a stagnant industry at the photographic level and with a clear physical limit when improving your hardware. Currently, there are no larger sensors. The second point is in the democratization of functions such as Super Zoom (Zoom improved with AI) on devices beyond its flagship. Creating a cloud platform from which you can drink lower ranges models allows you to honor an experience similar to that of a high range in cheaper models. “The algorithms have been increasingly improving since December last year, when this function had just left. And if you compare the future with what is now, five months later, you can see that the cloud -based algorithm is updated every two weeks is becoming remarkably more real.” For honor it is also especially important The improvement margin through updates that allows AI. Honor takes it seriously: they update it every two weeks. The key here is not alone in time, it is in how. System updates can be installed or not, depend on storage space and hardware requirements. Luo says that, using the cloud, they could update the algorithm daily if they wanted and access to it would be immediate. The second great unknown has to do with profitability. Using Google’s cloud sounds good, But someone has to pay it. Here is surprising the transparency of Luo, who explains that honor is still debating what the business model will be and if they will end up charging users or not to use these services in the cloud. Here, Luo explains that honor does not pay for users or requests, but for QPS (consultations per second). In other words, for the ability of users to access the cloud service, and thus their costs do not depend on user behavior. It is, currently, its way of making this business sustainable, although it makes it clear that it is something that is being worked on and discussing internally. Betting everything to the cloud brings an inevitable question, What happens to the privacy of users. Honor explains that its AI cannot be used without prior consent of the user (it appears from the configuration assistant), and secondly, that all photographs that are uploaded to the cloud to be processed are eliminated after being treated. On the future of photography, Luo closes with a metaphor. At the beginning of the history of automotive, the gearbox was manual. Subsequently, it went to automatic changes and, today, We are already talking about autonomous driving. And yet, we still need drivers. For honor, the AI ​​will allow any user, regardless of their degree of skill, obtain the best photograph in any scenario. For expert users, it will be a co-pilot in editing functions, elimination of elements and post-foto work. Image | Honor In Xataka | … Read more

Bill Gates and Warren Buffet have shared the same key to be successful: choose what to focus on

by

Bill Gates’ father brought together several people, among whom He was Warren Buffett, and asked what it was, in a word, The secret of his success. Both Microsoft’s founding millionaire and his good friend Buffett responded exactly the same: focus “You must focus. Eliminate distractions. Commit with only one thing and become excellent in it. “These are some of the advice that insistently repeat many productivity experts, such as the author of ‘Atomic habits‘, James Clear. This idea sounds logical. However, the big question for those who read those advice is How to know what to focus your energies. Experience before choosing How to know what to dedicate your attention and energy if you don’t know what really interests you? That is one of the questions you must answer before asking yourself What to focus on. Before deciding on what to concentrate your energy, it is necessary to try different paths. As Clear tells In your personal experienceDuring his first year as an entrepreneur he made many mistakes: “I launched my first product without having an idea who would sell it (big surprise, nobody bought it).” Therefore, your recommendation is Do not get obsessed with a single idea will work. It is necessary to try between four and five different alternatives for a while and, if it does not convince you, go to the next. This approach to “try things until something is easy” is essential because, regardless of the objective, it must adapt to your nature and skills. If you are looking to be more productive, experience with several Organization techniques. However good they are and no matter how much they work To people in your environment, you may not adapt to your way of working, To your biorhythms or your way of processing the information. Simply stop committing you to work with you and try Another different technique. The same happens if your goal is to start exercising, prove different sports. Maybe the Running Don’t be yours And it seems bored, and what you really enjoy is yoga or paddle. As the author of the Best seller on productivitythe important thing is not to obtain that a single option must work at all costs. Leaving behind what does not fit with you will allow you to discover what best suits your personality and lifestyle. Choose and Persevear: Invisible work Once you have experienced enough to discover what fits you and what is not, it is time to decide What are you going to focus on. As Clear explains, there comes a time in the process in which you don’t need more information, you just need to make a decision. This is one of the most difficult moments, because it implies putting aside the constant search and commit yourself to a single option. It’s time to focus. From here, perseverance becomes fundamental. Real progress It is not usually visible at the beginning. For example, you must be aware that, if you start going to the gym, you will have to do thousands of repetitions before noticing physical changes. If you want to be a great chef, you will first have to cook many mediocre (or bad) dishes. As Ira Glass pointed outfounder of the podcast This American Life“Your taste is good enough to notice that what you do disappoints you.” That is, only through repetition and constant learning the basis of success for a project, regardless of its nature, begin to lay. It doesn’t matter if it’s about Study oppositionsimprove your productivity, read more either Acquire new habits healthy The practice and art of simplifying Excellence is achieved with constant practice. After going through the phases of experimentation and hard work, the time comes when you can start simplifying. James Clear summarize it like this: “Only after completing the repetitions you will understand which parts of the task are fundamental for success.” It is then, when You have created a solid systemWhen you can Cut processesbetter choose your tools and eliminate what does not provide value. Getting something simple is, paradoxically, the most difficult. As wrote Blaise Pascal: “If I had more time, I would have written a shorter letter.” True mastery consists in knowing exactly What is essential and what is accessorysomething that is only achieved after a lot of practice and learning. Each person has their own rhythm, but the path to simplicity and approach inevitably happens through experience and perseverance. In Xataka | Lack of motivation is a problem for productivity.

The Granada particle accelerator is born today. Thanks to him Spain has the key to nuclear fusion

by

Today is a crucial day for IFMIF-DONES (International Fusion materials irradicion facility demo-eraned neutron source). This very important scientific project is closely linked to ITER (International Thermonuclear Experctor reactor), The experimental reactor of nuclear fusion that An international consortium led by Europe He is building in the French town of Cadarache. Ifmif-Dones, however, resides in listening to, a town in the province of Granada. The construction works of this last installation began in mid -September 2022, but today it is a very important day for both Granada and all of Spain. And it is because the Council of Ministers will approve today the investment of almost 200 million euros required by the start of the construction of the IFMIF-DONES linear particle accelerator. This machine is the authentic heart of this scientific installation, and, therefore, the ingenuity that will place Spain in The nuclear fusion map. The tuning of this linear particle accelerator will cost approximately 450 million euros, although the Andalusian Board will contribute half of this money. However, this is the cost of the accelerator; The IFMIF-Dones project will completely cost about 700 million euros. Spain will contribute half of this capital. To this figure we must add another 50 million to carry out its implementation. In addition, the operation of this avant -garde research center will have an annual cost of about 60 million euros, of which Spain will assume 10%. It may seem a lot of money, but we must not forget that those responsible for the project are convinced that The economic and scientific return Ifmif-Dones will far exceed your cost. What is Ifmif-Dones and why it is crucial for the future of nuclear fusion Ifmif-Dones is one of the three fundamental pillars of the nuclear fusion building in whose construction the European Union is involved. The other two are iter and demo. The experimental nuclear fusion reactor that is currently being built in the French town of Cadarache seeks to demonstrate that the merger at the scale that man can handle works, and also that it is profitable from an energy point of view. However, Iter does not aspire to produce electricity. That will be demo’s task (Demonstration Power Plant), an installation that will take the technological advances that will have shown to function correctly in Iter and take them one step further to establish themselves as The authentic precursor of commercial nuclear fusion reactors. However, without Ifmif-Dones there will be no demo, so Granada is now the center of attention. The fusion of a deuterium core and another tritium triggers the production of a helium core and a neutron that is fired with an energy of about 14 MEV To understand in all its extension what is the role of the IFMIF-DONES project, it is necessary that we briefly review the foundations of nuclear fusion. One of the biggest challenges facing the technicians who are involved in the tuning of nuclear fusion reactors by means of magnetic confinement, such as Iter, consists of recreating inside the vacuum chamber of these sophisticated machines the necessary conditions so that the deuterium and tritium nuclei are merged. However, this is not everything. When this reaction takes place the fusion of a deuterium nucleus and another of tritium triggers the production of a helium core and a neutron that is fired with An energy of about 14 MEV (Megaelectronvolts). The problem is that the neutron lacks net electric charge, so it cannot be confined inside the magnetic field that, however, does retain the deuterium and tritium nuclei, which have positive electric charge. This is the reason why when it originates as a result of the nuclear fusion reaction, this neutron is fired towards the walls of the vacuum chamber with enormous energy. This particle is very important because in practice it will be closely linked to the production of electrical energy in nuclear fusion reactors, but, at the same time, it represents a very aggressive form of radiation that can significantly degrade the materials used in the reactor. The components that will be most affected by the direct impact of high energy neutrons and the most intense heat flow are the internal wall of the vacuum chamber and the Blanketthat it is a mantle that covers it and that has as its purpose Regenerate the tritium that it is necessary to use as fuel in the nuclear fusion reaction. This is the reason why it is crucial to develop new materials that are able to support the flow of neutrons and guarantee, therefore, that the reactor will have a prolonged operational life. IFMIF-DONES linear accelerator will produce high energy neutrons with the intensity and volume of irradiation necessary to test candidate materials This is, neither more nor less, the purpose of Ifmif-Dones. And to carry it out it is necessary to put ready -to -set facilities to allow the technicians involved in the project to evaluate the properties of candidate materials to intervene not only in demo, but also in future commercial nuclear fusion commercial reactors. The task of this project invites us to intuit what the heart of Ifmif-Dones is: a source capable of producing high energy neutrons with the intensity and volume of irradiation necessary for Test candidate materials. And this source of neutrons will be nothing other than a linear particle accelerator that will help IFMIF-DONES scientists to try, validate and qualify the materials that in the medium term should reach future electric power production plants through fusion.

Losing weight without losing muscle is the great challenge of drugs such as Ozempic. A protein keeps the key to face it

by

It is usual for us to often get news about hopeful scientific advances made in mice. These experiments always leave a question in the air, if the discovery can be applicable to humans. This does not always happen, but sometimes MITCH Silence the expression of a simple protein in our muscles can lead to weight loss and, more, more, It can allow us to lose weight Without putting our muscle mass at risk. The protein in question is called Mtch2 (Mithochondrial Carrier Homolog 2), but has been nicknamed “Mitch” by those who study the compound and its effects. The last analysis of this protein and its associated gene has observed that its “erased” in human cells causes in these lower efficiency Energy What is perhaps more important, this silenced causes cells to stop using carbohydrates as a priority energy source and in place they preferably use body fat. Different fuels. The cells of our body need energy and billions of years of evolution have given rise to a series of biological mechanisms that allow us to maintain a calorie reserve that allow us to feed these cells in times of greater shortage. These mechanisms imply that our cells can resort to different fuels according to the situation. While the carbohydrates we consume and the fats that we use as a reserve are the main fuel Ozempic. From mitones to mitochondria. According to Explain the responsible teamthe new study has its bases in a previous experiment conducted with mice that observed in the rodents an “improvement” in their body composition in the form of “protection” against obesity and the development of more muscle fibers. This accompanied by greater consumption of greater oxygen consumption and an increase in resistance. The results were promising but left the team with a doubt, if it would be possible to “inoculate” the body against obesity by silencing the expression of a protein without this negatively affecting muscle mass. To look for an answer, the team went on to focus on the role of the mitochondría, the organelle in charge of providing energy to the cell. The key is in the fact that the “mitch” protein plays an important role in the merger of the mitochondria, a fusion capable of increasing the efficiency of these organelles. By silencing protein, organelles would lose the ability to resort to this fusion which also implies less efficiency and thereby a greater need to consume energy resources of our body. It only remained to prove if this was also true in human cells. Less efficiency, more consumption. They thus verified that by silencing the protein in human cells, the “mitochondrial network” was undone and, as expected, energy efficiency fell. This left the cell in a “permanent state of energy deprivation.” And what is more, the team also found that this led to the cells to prioritize the use of fats as a primary energy source, instead of other possible sources such as carbohydrates. “After erasing Mitch, we examined, every few hours, the effect that it had in more than 100 substances that take part in the metabolism of human cells,” pointed in a press release Sabita Chourasia, co -author of the study. “We saw an increase in breathing, the process in which the cell produces energy from nutrients, such as carbohydrates and fats. This explains the increase in muscle resistance of previous experiments in mice.” The details of the study were published In an article In the magazine Journal embo. An intermediate step. The study takes an important step in the long process between the first results in animal models and the design of a treatment for weight loss based on what was learned. In following studies, the team intends to elucidate new aspects about Mitch’s role in the accumulation of fat in the body. The fact that women usually have higher levels of this protein can help researchers discover if Mitch is also responsible for the differentiation of fatty cells.

Baidu believes to have the key and has registered it in a new patent

by

The idea of ​​talking with our pets has been feeding the collective imaginary. And although we continue to maintain a conversation with a dog or a cat in the style of Doctor Dolittleartificial intelligence (AI) begins to explore a much more realistic land: to interpret how they feel. The last sample comes from China: BAIDU has requested a patent proposed by a system capable of translating the emotional state of animals into understandable language for humans. An emotional translator, not a talk with your dog. The application, submitted by the company to the State Office of Intellectual Property of China raises a system that does not intend to translate barking or meowed in human phrases as if they were words, but to identify relevant signs of animal behavior (such as voice, gestures or physiological changes) to estimate its emotional state and express it in natural language. In other words: it’s not about talking to animals, but better understanding what they feel. As Sina collectsthe key is to build an emotional interpretation channel that allows humans to react to what animals, obviously, cannot express in words. The difference with respect to other existing tools is in the depth of the analysis. Most initiatives in this field focus on the superficial interpretation of sounds or expressions, but do not capture complex emotions. Baidu’s proposal aspires to break that limit. Artificial intelligence with multimodal approach. The system key is in its integral approach. According to the technical summary of the patent, the method relies on technologies such as automatic learning, deep learning and natural language processing. These three pillars allow to process large volumes of data and extract relevant patterns in real time. Innovation is how the different signs collected are combined: vocalizations, postures, behavioral variations and physiological data. All this is analyzed jointly to avoid errors that usually occur when it is based on a single source. The ultimate goal is to achieve a more precise emotional reading, with less margin of ambiguity. Applications in Care, Conservation and Animal Study. The potential use of this technology goes far beyond the domestic sphere. According to the document, it could be used to improve the welfare of pets, adjusting their care and company based on their mood. But it could also have an important role in scientific research, helping biologists to better understand the behavior of rare or endangered species. In reservations and conservation centers, these types of tools could become an ally to anticipate states of stress or discomfort before they manifest themselves in an evident way, facilitating the task of the staff. It is not yet a product. As with any patent, its publication does not imply that technology is available or becoming a commercial product. In fact, South China Morning post points That the evaluation process can be extended for more than a year, and Baidu has not announced concrete plans to develop it in the form of a device or service. For now, what the company poses is a technical basis that opens a new chapter in the relationship between humans and animals. One in which, perhaps, we can begin to understand more precisely what those who cannot talk to us with words feel.
