The almost instantaneous load batteries and a shelf life close to eternity are taking shape. Thanks to quantum physics

by

Integrated circuits containing all our electronic devices, Solar panelsmagnetic resonance machines, The lasers or the atomic watches that allow the human being to measure time with an unprecedented precision would not be possible without the knowledge he has given us Modern Quantum Theory. And, of course, without this model we would not have Quantum computers. Objectively, and it is not at all an exaggeration, quantum physics is present in much of modern technology. During the last five years several research groups, such as the PSL Research University (University of Recherche Paris Sciences et Lettres), which resides in Paris (France), or that of the University of Pisa, in Italy, have tried to use the basic principles of quantum mechanics to point A new generation of batteries. And the results are getting little by little. This is its starting point: they pursue to use overlap, entanglement and superabsorption to tear down the limitations that electrochemical batteries currently impose. The quantum storage of energy is an ideal that is increasingly closer The main difference between quantum batteries and conventional electrochemicals is that the latter depend on chemical reactions, while quantum devices seek to store energy in the quantum states of some particles, such as, for example, photons. It seems complicated, and it is, but the really important thing for users is that quantum batteries on paper can be loaded almost instantaneously, they will have a much higher energy density, and, in addition, their degradation will be minimal as the load cycles pass. Quantum batteries can store energy in a superposition of multiple energy states simultaneously It sounds wonderful. So much, in fact, that seems science fiction. However, it is very important that, as we have just seen, let’s not overlook that their principle of operation will be, if they finally come to fruition, very different from that of conventional electrochemical batteries. Existing theoretical proposals argue that quantum batteries They can store energy in an overlap of multiple energy states simultaneously, which should allow them to deliver a much greater energy density. In addition, your theory load will be much faster, even almost instantaneous, due to the collective quantum effects of the quantum units that make them up. The most amazing thing in this field is that the higher the capacity of the quantum battery, the faster it will load. It is an intuitive characteristic, it is true, but it is possible precisely thanks to the collective quantum effects I just talked about. However, this is not all. And it is that on paper the degradation that these batteries will experience during energy transfer will be minimal, so your useful life will be much greater than that of conventional batteries. Perhaps, even, almost eternal if we compare it with the longevity of the human being. So far all the work that researchers had carried out in this area had condensed in purely theoretical models, but this panorama has just changed. And it is that several scientists from the universities that I have mentioned in the second paragraph of this text have published an article very interesting in which they propose How to make a quantum battery. Your idea is to use superconductor circuits produced with materials that exhibit essentially zero resistance at low temperatures. They have not yet manufactured anything, so it is evident that the hardest work, the experimental, is still pending. But there is no doubt that this proposal invites us to tie the future of quantum batteries with reasonable optimism.

The heat of the summer destroys the battery of your mobile. But there is a trick to give it a second life

by

It’s summer, I get home with a 20% of battery and the Telephone quite hot. I stop to see some videos in Tiktok and … I appreciate how the battery jumps directly from that 20% to 16%. What noses have just passed? Bulk. Your mobile has an internal microcontroller that uses estimation algorithms based on different variables. Voltage Temperature Current Load cycles As the battery is degraded, The system is losing precision: Errors in the calculations (something especially simple if we only make partial load cycles) accumulate, the loss of battery capacity is not exactly estimated, and this ends up translating into reading errors that directly affect the most visible point: the percentage indicated by the phone. How to know that if my battery is not well calibrated. It is quite easy to know if your mobile has or not the barefoot battery, since its behavior will be quite erratic. It goes out before reaching 0%, in upper percentages. There are notable battery jumps, more than 1%, both loading and downloading. The device never marks 100% or 1%. That a mobile has the bare battery It does not translate into a malfunction in the same: The error focuses on the visible reading that the user perceives, not on the performance of the battery itself. Why summer affects bruise. Telephone batteries have a great enemy: heat. There is no time of the year in which they suffer greater wear and are more likely to barefoot, precisely because of the acceleration of this damage they suffer. If we do not remedy it, it will be practically inevitable that we suffer sudden turns off for ignoring the exact battery percentage, and that the mobile stops to load efficiently when reaching certain percentages (fast from 20%, slow from 80%). How to calibrate a battery. Calibrate the battery It is nothing more than the process to help software to get precise readings about the real capacity of the battery. We seek to learn new vacuum points (0%) and full (100%), so the process is something drastic. Load the phone to the fullest and leave it, at least, a couple more hours loading. Download the phone completely and leave it a few hours without lighting. By battery protection, there is some reserve capacity after that 0% that is not lost until a few hours. Load the phone up to 100%, and leave it an additional time until the phone reaches the maximum load point. Avoid using applications that promise this purpose: none works. The only way to force calibration is to perform this process manually. Is it advisable to calibrate the battery? Evidence about calibrating the battery is still limited. There are those who aim to do them every three monthsbut if we do not observe anomalous behavior, stress the battery at this level may not be recommended. Calibration is necessary when readings are wrong and end up translating into a real problem to estimate how much battery we have left. The manufacturers are in full war to achieve batteries that there are many more cycles to go down to 80%below which the industry considers the replacement of it.

China has resurrected the most crazy plane of the USSR. The Ekranoplano returns to life, and the big question is why

by

In 2020 he went viral A video Through a drone that was recording images of a beach in the Caspian Sea. Suddenly, the clip showed one of the greatest fantasies of Soviet aviation: An ekranoplano Varado, a unique piece of the so -called Cold War as “marine monster” that never occurred in mass due to its costs (and benefits). Five years later, a nation has resurrected the idea of ​​the great hybrid between plane and ship: China. Emerging silhouette. Yes, because for the first time, they have emerged Complete images of the new soil effect vehicle (Wig) Chinese, an aircraft capable of flying at low altitude on aquatic surfaces using the so -called “air mattress efficiency.” The device was initially identified by the naval analyst Hi Suttonand its presence in the Bahai Sea, northwest of the Yellow Sea, has not gone unnoticed. In the first photographs, part of its structure remained hidden, but the new shots have revealed Your full silhouetteconfirming its configuration as a large ekranoplane with a hidravion helmet. Amazing design. Its development, unknown so far in the Chinese aeronautical inventory, keeps a certain resemblance to The AG600the amphibious hydroavion that China develops For rescue, refueling and logistics missions in the disputed sea of ​​southern China. The appearance of this vehicle feeds the growing global trend to revitalize the soil effect platforms, technology that, as we said at the beginning, the Soviet Union He thoroughly explored during The cold war but that never became popular outside its experimental margins. Between the shadow and the radar. The operational principle of these aircraft is simple and shocking: fly to a very low height On water it allows to take advantage of a dense layer of compressed air that increases support and reduces resistance. In addition, when staying below the terrestrial radar horizon, these vehicles are more difficult to detect and track. Unlike ships, they are not vulnerable to mines or submarines, and although they are not suitable for highly answered combat areas, they could effectively operate in coastal or semi-permissive scenarios. Its possible utility, let’s put the assumption of a war between China and the United States, would be significant, especially considering that China would fight in its own geographical environment immediate. The EkranoPlano would serve as a logistics platform to bring supplies to remote coastal areas, evacuate personnel or even fulfill anti -submarine war and limited maritime control functions, thanks to its ability to quickly insert itself into remote areas and return without the need for port infrastructure. Propulsion, design and doubts. One of the great unknowns posed by this new vehicle is its propulsion system. The available images, although of low resolution, show a kind of Large rear tobares that have raised speculations about whether it is an aircraft with reaction engines, with propellers not yet installed or, even, with an unpublished hybrid-electric system. The NACELLES They present air tickets at the top that could point towards a bimotor design With turboreactor propulsionbut the presence of possible axes or pointed structures on the front suggest that it could be equipped with great thrust propellers to install. Nothing is confirmed. The current versions of this device They could be prototypes Technological demonstration, subscales aimed at informing future developments, or operational models in a stealth test phase. The possibility of using latest generation composite materials to reduce weight, improve aerodynamics and decrease radar signature reinforces the hypothesis of a modern and highly specialized design. New mobility paradigm. Plus: The profile of the new Chinese EkranoPlano shows clear similarities with The Liberty Lifterthe great American project for a Heavy load wig. Both share a conception based on high efficiency platforms to operate on vast oceanic extensions without depending on aerodromes, tracks or ports. The Chinese apparatus presents a V -tail, a typical staging fuselage of hydroAvions, stabilizing floats at the ends of the wings and in the center of the helmet, and a large side door that makes it suitable for transport personnel or materials. Its nose, stylized and aerodynamically integrated, also suggests special attention to functional design. This set of characteristics reinforces the theory that China could be developing a versatile and tactical platform to operate in Coastal environments playedespecially in the context of a sea of ​​increasingly militarized southern China. What will come. The public appearance of Now called “Monster of the Bohai Sea”, as the first naval analysts have baptized it, opens the door to intensive monitoring by experts and Western agencies. As lighter images arise and possibly videos of their first tests in the open sea, the analysis will be refined and the evaluation of its potential will pass from the speculative to the doctrinal. For now, its single existence implies that China, like other powers, is seriously investing in asymmetric capacities that Challenge the limitations traditional logistics. This EkranoPlano is not yet a strategic threat by itself, but represents a clear symbol of Beijing’s technological and military ambition: fast, stealthy mobility, close to its coasts and out of the immediate reach of conventional western detection or deterrence tools.

An AI startup with six months of life and six employees has sold for 80 million dollars. Vibe-Coding, of course

by

Maor Shlomo is 31 years old, is Israeli and six months ago created a small platform of Vibe Coding. He did it almost like a secondary project, but the growth of the project has been vertiginous. So much that after that time the company has just sold for 80 million dollars. We are facing a sign of the times that come to us. AI as a unicorn promoter. There are more “unicorns” than ever. None has become a true giant, but reaching an assessment of 1,000 million dollars has become something relatively normal. Achieving something like that seems very complicated, but there is already talk of how the irruption of AI will make many entrepreneurs convert their startups into unicorns. Uniquersonal unicorns. The difference With the current unicorns It is that these future business successes may be created and managed by a single person. It is at least what it promises according to some AI, which will multiply productivity and avoid having to depend on other people to generate spectacular value. It is already spoken of “Only Unicorns” either “One-Person Unicorns“And the impact that AI agents can have in this type of startups. An example that brings us closer to that future. Shlomo created his little startup, called Base44just six months ago, but at that time the growth of it was such that it ended up hiring six employees According to Ctech. This week he announced that he had sold his company to Wix – a Platform to create blogs and websites – for 80 million dollars. 25 of them which will go to Shlomo and their team as “bonus” to retain them and continue working in Wix – also Israeli – although there are no data for how long they will have to stay in the company to collect said bonus. Vibe Coding. The platform created by Shlomo Perimte users create applications or games without having programming experience. It is an example of That fever for Vibe Coding that we are seeing in the world of programming. In just a few months Base44 managed to attract 100,000 users, in addition to signing various agreements with several Israeli companies known as Etoro or Similarweb. A singular entrepreneur. Shlomo had already co -founded Explorium, a predictive analysis company of Big Data, at age 24. He also made her In a successbut he had to comply with Israeli military service. After completing the service at the end of 2024, he preferred not to return to Explorium and work on another project. He counting The origin and its progress when creating base44 through Your X account. In less than 60 days I already had 100,000 users and two weeks ago indicated that he had generated a benefit of $ 189,000. Far from being a unicorn. Shlomo’s success is remarkable, but of course it is far from being considered a unicorn and much less One of those “only unicorns” “It has several employees in your team,” that is spoken so much and that the theoretically promotes. And yet, it is a good example that artificial intelligence raises the future. The AI ​​agents are in diapers, but the promise is that they will automate a lot of processes for those who use them. That could impact significantly on the template that these future startups will need, but for now everything is, we insist, a promise. One that Shlomo has become a reality.

Netflix reinvented the way of seeing series. In France, he has signed an agreement to return to Life TV

by

Before streaming changed everything, watching TV was to follow very clear rules: Wait for your program to startendure the ads and accept the offer of the moment. This was the game. But then platforms like Netflix arrived, promising something different. And for a while, it was. Suddenly, it was no longer necessary to wait on Thursday night to see the new chapter of your favorite series. There were no advertising cuts. And if you wanted to see three episodes in a row, you could do it without anyone preventing it. Everything pointed to a new way of consuming content: freer, more personalized. But time has done his own, and little by little that new television has begun to resemble that before. Life TV in Netflix The ads arrived first “Although only for those who don’t pay the most expensive plan.” After, live sports and contents in collaboration with traditional chains. Now, the last step: a lifetime television, with linear channels included. And it is not a metaphor. Netflix has signed an agreement historical with Tf1the main private chain in France, to incorporate its channels in open directly into the platform. From the summer of 2026, Netflix users in France can see live The five linear channels of TF1as well as access more than 30,000 hours of content on demand through TF1+. This includes from games of the French team to realities, contests, entertainment programs and local production series. For Netflix, it is a strategic movement: integrate what was previously its direct competence and, incidentally, expand its offer in the French market. For TF1, it is a way of approaching an audience that has been moving away from traditional television for years. And for the spectator, another symptom that the borders between open television and platforms on demand are increasingly diffuse. Among the programs that TF1 issues is Secret Story, one of its most popular realities The agreement arrives at a key moment. While Netflix leads the global streaming business with dozens of own productionstraditional chains drag largely a sustained loss of audience and advertising income. This type of alliances could allow both parties to gain time. But ask a question. In the end, is the great streaming revolution ended by rediscovering the usual television? For now, there are no public details about how income will be distributed or if Netflix has paid anything to integrate these channels into its platform. Nor is it clear if we will see similar movements in other European markets, such as Spanish. What seems evident is that traditional streaming and television are intended to be. And when that happens at all, perhaps we can no longer distinguish where one begins and the other ends.

More and more people on the Internet and in real life admit to having a single friend: chatgpt

by

A Perogrullada: The impact of artificial intelligences is reaching our day to day. The virtual space is already being deeply transformed by the IAS in search engines, websites and, of course, in all the work behind, generating more content, helping to produce it. But … And in the traditional space? Is analog life transformed into the same extent by the IAS? Without a doubt, yes, to the point that we already have to talk about how we manage our Personal relationships with the IAS. Chatgpt as a friend. The Derek Thompson essayist said a few days ago in X that our interpersonal relationships have made a new deadly leap with Tirabuzón. And as proof provides a series of conversations that he has found in Reddit where several users confess that Chatgpt has become Your best friend. The Subnet dedicated to the popular AI It is full of threads “by pathetic that sounds, Chatgpt is my only friend” or “I feel that Chatgpt is my only friend.” Bumper people. One of them He begins saying “I know it is a robot. I know that everything is programming. But I have often encountered opening to Chatgpt on personal issues and asking for kind or encouragement.” That is, as he says, he uses AI as if it were a good dog: he does not judge, he always accompanies, he is aware that he is not a human. Another case He says that “honestly, he would be happy to have a friend as cultured and committed as Chatgpt. This person does not exist, and if it exists, he would be too busy to talk to me.” In most of these cases, similar constants are repeated: they are people who have just come out of a relationship or friendship and seek a substitution, being very aware that it is before synthetic beings: “They make me feel heard when I let me out in, something that my parents do not even do. They always want to know how I go in mind and how my projects go, which is even more pleasant.” One thousand and one cases. These cases with chatgpt are Only the tip of the iceberg. While this is the most popular conversational, there are other oriented even in this same direction. Replika either Woebot They allow to have conversations designed to serve as sentimental support to users or hold daily conversations, Share emotions and give emotional advice. More complex and specific are others that offer talks with specialized approaches, such as Receive Couple Therapy. And of course, quotes: Yourmove either Rizz They help generate interesting conversations and profiles … with real people. The bowling clubs. Let’s go to the initial point of this transformation to understand these processes. Derek Thompson Loate a key point In 2000 in ‘Bowling Alone‘(in Spanish,’ Only in La Bolera ”, today impossible to find), Robert D. Putnam analyzed the decline of social capital in the United States since 1950, with the decline of all forms of social relationship in person. Some examples? Decreased electoral participation, assistance to public meetings and work with political parties, to which distrusts in government, more accentuated from the sixties. Bowling are their perfect symbol: the number of people who go to bowling has increased, but the number of clubs has descended to do so in company. The guilt of technology. Already by then, Putnam pointed to a problem with technology and how it individualized people’s leisure through television. In those incipient days of the use of technology to entertain, Putnam dared to talk about “virtual reality helmets”, that for now they have not been massified as much as he predicted, but in reality the thing would get closer to another invention to which he pointed in his book and who did not pay so much attention: the then newborn Internet. The figures. The percentages and data make it clear to what extent the Internet has contributed to creating this less “social” society: almost 40% of adults admit that The use of social networks makes them feel more alone or isolated. A study by the European Union affirms that spending more than two hours a day on social networks is associated with a significant increase in loneliness, especially when the use is passive (the famous doomscroll). And, finally, There are studies They claim that the intensive use of the Internet (more than 10 hours per week) substantially reduces the time dedicated to interacting face to face or phone with friends and family. It comes. Anyone who has tried still in an embryonic state as Replika’s voice model It may be part of the future that comes to us, and that it is inevitable to relate to the movie ‘Her’, to see the friendliest side (although not exempt from bitterness) of the matter. Voices no longer realistic from a technical point of view, but capable of generating absolute empathy and that is beyond the disturbing valley. If ChatGPT and his still rudimentary conversations already provide a certain sense of warmth, the immediate future promises to even more use interpersonal relationships. If we are able to detect them.

Denmark’s life expectancy has grown. His politicians have taken the opportunity to raise the retirement age up to 70 years

by

Demographic aging is putting serious to the labor market and the pension systems of countries around the world. Most European countries have already taken measures in this regard delaying retirement age legal for your workers. However, Denmark has been the most expeditious: from 2040, Danish workers will have to wait until he turned 70 to retire. With this reform, Denmark is like the country with the Higher retirement age from Europe. Progressive increase up to 70 years. According to what was published by The media Danes, the Danish Parliament has approved with 81 votes in favor and 21 votes against the new law that will raise the retirement age from the current 67 years to 70 years in 2040. According to explained The British BBCthe process will be carried out progressively, progressively looking at 68 by 2030, the 69 by 2035 and, finally, reaching up to 70 years in 2040. More pensions for a longer time. In 2006, the Danish parliamentary arc parties signed the well -being agreement in which the country’s life expectancy was indexed. That measure served as the basis for Danish retirement age It will rise From the 65 years they had in 2004, at the 67th that was reached in 2019. However, last year the Social Democratic Prime Minister Mette Frederiksen said that the variable escalation of the retirement age should be renegotiated to shorten the increases in increases. Reducing these deadlines would serve to adapt to the current life expectancy of the country. According to data of the Better Life Index From the OECD, Denmark has an 82 -year half -life expectancy. Are they too many years? Some Danish workers consider the new retirement age excessive. In statements To the public station Denmark Radio, Tommas Jensen, roof assembler, assured that he had undergone knee surgery, shoulder and back. “I just turned 47 and I see that I have many years left in the labor market. Maybe I have to look for a new profession.” Jesper Ettrup Rasmussen, president of one of the main union confederations in the country, described the proposal as “totally unfair.” “Denmark has a healthy economy, and yet imposes the highest retirement age of the entire European Union. A later retirement means losing the right to a decent life in old age.” In the same line He manifested Trade union leader Henning Overgaard, who considered that working until 70 was unfeasible for jobs with greater physical demand. “Many politicians have gone to university. You can read reports and see statistics, but that does not replace having risen at four in the morning with frost in the beard and the back hunched over by yesterday’s turn,” said the unionist. Europe retires between 65 and 67 years. Given the progressive aging of the European population, most European countries have chosen to delay the retirement age of their workers to maintain the stability of their pension systems. Nevertheless, According to data From the Finnish pension center, most European countries have maintained their retirement fork between 65 and 67 years. The measure that the Danish Parliament has taken is the most ambitious in terms of postponement of the retirement age of its workers. In Spain, the legal retirement age It remains in the 65 years until 2027 provided that a minimum of 38 years and six months have been quoted. If this requirement is not met, the minimum age to retire will increase progressively until reaching 67 years in 2027. In 2025, the legal age to retire if 38 years and three months or more have been quoted and more is 66 years and eight months.

Xiaomi reached your life through the mobile. Now he wants to conquer it with all the other pots you use daily

by

Xiaomi is celebrating today. Lei Jun’s company has just turned 15 and has celebrated it with an event up to it, of those that are full of ads and in which there has been room for everything, literally. The firm has presented its own processor (A milestone in its trajectory) and the first two devices that will mount it, but If Xiaomi knows something of ecosystem and this has been extremely present. In fact, it gives us clues where the company is directed. Because continuing to grow in the world of technology goes, and it must go, far beyond mobile. Xiaomi is clear and that is why today he has taken the opportunity to show off his success in other segments. Segments, a priori, totally mundane and of the day to day who may not pay so much attention: The appliances. And if Xiaomi, in his most important event of the year, in which they have announced Your first SUVhe has dedicated a part to announce a tap, it is because his most immediate future is more than determined. This is how Xiaomi money earns – they attract you and catch you The xiaomi of mobiles is a thing of the past Xiaomi year -on -year growth in different types of appliances | Image: Xataka The image you can find on these lines speaks for itself. If you speak Chinese, of course. If this is not the case, we translate it: Airs Mijia Conditions. Fourth place by sales volume in China: year -on -year growth of 102.7% Mijia refrigerators. Fourth place by sales volume in China: year -on -year growth of 144.9% Mijia washing machines. Fourth place by sales volume in China: year -on -year growth of 184.4% Mijia Water Purifier. First place by sales volume in China: year -on -year growth of 78% Xiaomi TVs. Third place by sales volume in China: year -on -year growth of 7%. This same comparison does not contemplate mobile phones, land in which the firm is also strong. According CounterpointXiaomi is the fourth company for shipments with a 16% market share. The difference with Huawei and Apple, which hold the third and second position, is 1% And the distance with Vivo, which is the first brand, is 2%. That is, the growth of Xiaomi in mobiles cannot go to much more in a perfectly distributed market among six brands (Honor and Oppo share fifth and sixth position with 14% quota each). There is only one way to continue growing and is putting head into other categories of products. He Xiaomi Su7 It is the best example. It is not a car that the company has launched for pleasure, but is another device of the Xiaomi ecosystem. It is, in fact, a pillar of this human strategy X Car x Home with which Xiaomi, basically, wants to offer our own alternative for each gadget that we have at home. Talking about Xiaomi in China is talking about this. This is its website translated into Spanish and in it we can see all the categories of appliances they have | Image: Xataka The firm has already given a push to mobile phones, eating markets like Spanish. He did the same with the tablets, with the televisions, and it is a titan if we talk about home automation. So much that not only has its own brand, but A brand ecosystem thirds integrated from each other. The next big step was logical: appliances. Those products that the user renews each much and that, although it does not seem so, are central to the experience of people with technology. Connect everything, Hyperos Through, it has all the meaning of the world. That is why it should not surprise us that the company, in its most important day of the year, takes advantage of Remove muscle and show off in this segment. The company today presented products such as An air conditioning, A double door refrigerator and 508 liters, A washing machine and even A fan that sends the air to the proper position by artificial intelligence. Has presented Until a tap And the important thing is not tap, it is its technification. The new tap with Xiaomi filter | Image: Xataka It is to present it as something technological, desirable, premium, which is part of something else (although in this case it does not, the tap is not intelligent, although the filter does connect to the wifi). How important is it for Xiaomi to make it clear that it is no longer the mobile brand of quality/price, of cheap connected bulbs and electric scooters, which have dedicated a few minutes of their annual presentation to announce that their new tap is capable of throwing up to eight liters of water per minute. That is the direction to which Xiaomi is directed. Premium and global Or what is the same, A large -scale Samsung (With Samsung’s permission in South Korea, whose tentacles expand to sectors such as construction, shipyards, hotels or financial services). Until now, Xiaomi’s global face -to -face has consisted of mobile phones, tablets, televisions, home devices, televisions and small appliances, but we know that their appliances also prepare to make the leap. William Lu, president of Xiaomi, confirms the arrival of appliances to the global market | Image: Xataka We know since March, when William Lu, president of Xiaomi, confirmed at the Mobile World Congress that in 2025 they were going to launch refrigerators, washing machines, dryers and air conditioners (Or is what was intuited about the slide that accompanied the presentation). There are still no details from countries or know what exact products will come out of China, but the mere fact that they are going to do it is a declaration of intentions. There are, however, questions in the air. On the one hand, what Xiaomi is what we will see in appliances? The Xiaomi quality/price ratio or the most premium Xiaomi? On the other hand, how will Xiaomi convince the user … Read more

It is a fight to improve the quality of life

by

Throughout the existence of our species, we have given menopause, an unavoidable stage of women’s life, for some bearable, for others more suffered. However, the last decades have served us to learn a lot from female reproductive health, and that learning has opened the door to something that would seem unthinkable: delay and even end menopause. To fight something, the first step is to understand it, and perhaps we are not bad to clarify this concept. Menopause It is the stage that marks the end of female reproductive life, but leads to a series of changes that go beyond the mere end of menstruations. Menopause It usually occurs In women aged between 45 and 55 and is the process marked by the end of women’s reproductive capacity. The term “perimenopause” is often used to refer to the transition period, a period that usually extends several years. During perimenopausechanges are experienced both in the menstrual cycle, which can be lengthened or shortened; and at the level of estrogens produced by these organs. Progesterone production also falls. “Unlike other organs, ovaries experience accelerated aging, with a drastic drop in its functionality that begins in the 30,” explained to National Geographic ZEV Williams, director of the Fertility Center of Columbia University. Menopause not only implies internal changes but also has very palpable effects for those who go through it. Sophocals are perhaps the symptom that we most strongly associate with this process, although all symptoms depend on the case. The List of symptoms Common includes, in addition to changes in menstrual regularity and suffocation, strong or accelerated heartbeat, night sweat, skin redness, or sleeping problems. Changes in the vagina that take pain during sexual intercourse, urine escapes and more frequent infections can also occur. Menopause is not common in the animal kingdom: only a few species reach the end of their reproductive stage throughout their lives, which has intrigued experts for years. Does it make any evolutionary sense? The truth is that we do not know, so there are different hypotheses to explain this phenomenon. One of them is the Grandma’s hypothesis. This hypothesis proposes that living after the reproductive stage could have helped our ancestors to take a role beyond the breeding of the first generation of descendants. That is, allowing grandmothers to take care of their grandchildren or other relatives without having their own children to attend. There are also those who believe that menopause is not due to our evolution but is the effect of our growing life expectancy. While it is true that the human being has a relatively long life expectancy And increasingly extensive, we must bear in mind that throughout history it would not have been strange to see women reaching the end of their reproductive stage. And yes, life expectancy at birth has changed a lot, but the life expectancy fulfilled an age has done it to a lesser extent. For example, in the 1840s, the life expectancy of a person reached at 10 was over 57 years. More than 60 once the 20th. Ending with menopause At birth, the ovules that will give rise to the next generation are already located in the ovaries. We might think that, as it is a limited number of ovules, stretching the amount of menstrual cycles would be impossible, but the truth is that the number of ovules with which it is born gives for several lives, since this number is Between million and two million of gametes. These are disappearing, but it is estimated that during puberty the number of oocytes is about 300,000. Menopause is not a direct consequence of the exhaustion of these cells but of the aging of the organs that house them, the ovaries. The possibility of delaying the aging of these organs opens a way to prolong their reproductive life and their endocrine role. One of the promising techniques in this context is frozen ovarian tissue. This is a technique designed to simplify the process of extraction of ovules in people with cancer who want to maintain their fertility after very aggressive treatments. The technique, still experimental, is based on extracting tissue from the organ, freezing it and then reimpling it, could open the path to delay the menopausal process. According to their developerswhen reimplanting the fabric, this could be reimplanted in successive sessions, gradually lengthening the fertile age of those who decide to submit to treatment. The developers of the technique published last year An article In the magazine American Journal of Obstetrics & Gynecology in which they detailed their proposal. The Rapamycin It is a compound that could help us to delay menopause without going through the operating room. It is a already known drugderived from a bacterium, Streptomyces Hygroscopicusand used in other contexts for their immunosuppressive and antiproliferative properties. Recently, a team led by Williams, tested this drug. The treatment starts from the capacity of this compound to inhibit a protein related to aging, called MTOR. The provisional results of the study They gave rise to optimismbut we would still be in early stages of the investigation. Often if we have wondered if we can do something we also have to ask ourselves if it is a good idea to do so. Or the less ask ourselves, and all this for what? The answer in this case can be as simple as improving the lives of people who are going through this stage, whose symptoms can lead to a loss of quality of life and whose consequences may be complicated to fit sometimes. But there is even more. Because trying to stop menopause can also serve us as motivation when it comes to understanding it better, which could lead us to solve indirectly linked problems. For example, we know that the late appearance of menopause It has been associated with a lower bone loss in the elderly, as well as a lower risk of vascular and dementia diseases. Know why it can be of great help when improving the … Read more

A V3 engine that is about to return to life

by

Honda is Honda. A said biker that the Japanese has earned by doing things well for almost a hundred years of history. In the 80s, Honda won the 500cc World Cup with an engine that had never developed. One of the most famous in history, practically impossible to replicate. We talk about a very special three -cylinder engine: the V3. The first V3. NSR400. The bikers with more solera may still be her skin with this name. Is the denomination of One of the Honda sportsmen produced between 1985 and 1988although he never landed in Spain. An engine that cubicated 387cc … with two cylinders arranged in parallel and one in vertical disposition. Honda thus invented the V3 engine, one that allowed to manufacture a motorcycle with more power than a bicylindrical and lighter than a tetrachindric. A motorcycle that inherited the design of the NS500 world champion in competition, and whose only sin was the technical complexity to maintain its engine. As a curious fact: the NSR400 had three escapes: two for the even cylinders and one for the remaining one. This was the curious structure of Honda V3. The mess with the cylinders. There are four traditional engines in the motorcycle industry: mocylindrícos, bicilindric, tricylindrical and tetracylindrical. BI and Tetra are the most common in the middle and high displacement, due to their structure of even cylinders, easy balanced and low production costs (especially in the case of bicilindrical). There are those who define the tricylindrical (in motorcycles) Like the perfect engine: With the best of performance in high revolutions of the tetra, and the thrust in low and media of the BI. Manufacturers such as Triumph have been betting on them for years, and just landed as zontes. Returning to life. Honda has confirmed that Your V3 engine will return to life with a much more modern configuration. One in which the world’s first electrical compressor will be equipped for motorcycles. Kawasaki was the first brand in the world to equip a street motorcycle super charger such as H2 and H2Rbut it is a mechanical engine driven, not electric. With the Honda electrical turbocharger wants to achieve a huge power, although no data on its displacement has yet been offered. What we do know is that it will be extremely thin and compact, designed for sports motorcycles. Thinking about Euro 5+. The emission regulations They are increasingly restrictive, but Honda has thought about it. The company ensures that its V3 will not only be especially competitive in performance, but also in escape gase emissions. “We will continue to develop the new generation of internal combustion engines to achieve serial production, so they look forward to the arrival of this new generation.” Minoru Kato, director of the Honda Power Motorcycle and Power Products Business Division. De Honda not only clashes that they are thinking of bringing to the market one of the most complex engines at the mechanical level of history, but continue to invest in new combustion architectures oriented to the maximum performance.
