Samsung and Apple brought ultra-thin mobile phones to the market with little battery life. China’s response: hold my tank

by

Samsung was the first, and Apple followed a few months later. The introduction of increasingly thinner mobile phones on the market did not meet any specific need, beyond reducing weight and thickness. Betting on this format, at least with the proposals of Western manufacturers, brought with it sacrifices both in camera and autonomy. In China they are clear that There is no need to sacrifice one thing or the other.. The Honor Magic8 Pro Air. Recently, Honor presented the Magic 8 Pro Air in China. The surname already tells us where the shots are going. It is a mobile phone of only 6.1mm It has the best MediaTek processor It has a 5,500mAh battery It has a triple camera system (wide angle, wide angle and telephoto). It turns out that it was possible. There are a few millimeters of difference between the Honor Magic8 Pro Air and its direct rivals, the iPhone Air and Samsung Galaxy S25 Edge. But the numbers speak for themselves. Honor magic8 Pro air iphone air samsung galaxy s25 edge dimensions 150.5 x 71.9 156.2×74.7x 158.2 x 75.6 thickness 6.1mm 5.6mm 5.8mm battery 5,500mAh Si/C 3.149mah Li-Ion 3,900mAh Li-ion camera system 50MP, 1/1.3″, OIS 64 MP, /1.2″, OIS 50MP 48 MP 1/1.56″ OIS shift sensor 200 MP, 1/1.3″, OIS 12MP,1/2.55″ The Honor device is 0.3mm thicker than an S25 edge and 0.5mm thicker than the iPhone Air. To give you context, there is a guitar pick difference and a 75% higher energy density in the case of the Chinese mobile. An outrage. Furthermore, China has shown that it is not necessary to give up a single camera to opt for this format. And when we talk about flagships, this point is key. The 10K club. Beyond demonstrating that in ultra-thin mobile phones, silicon-carbon technologies allow energy densities that were impossible until a few years ago, the “10K club” is adding more and more participants. Chinese phones with normal thickness or even less than usual with 10,000mAh batteries. The last one to join the club was Realme P4 Powerthe first mobile phone in the world with a 10,001mAh battery. These are figures that double the usual standard in the rest of the ranges. The answer? There is neither nor is it expected in the short term. China has been ahead in the race to deploy silicon-carbon batteries, one that is not so easy to get into. Such high density batteries require: Greater regulations at the transport level, especially in the European Union. Much higher prices, as Xiaomi advanced. A durability risk not yet proven. Moving towards silicon entails important changes that traditional manufacturers, accustomed to a conservative and slow strategy, are not yet willing to take on.

Bugatti has brought the Veyron back to life in the worst possible way: taking advantage of nostalgia

by

I confess: I have laughed at my parents. Not once, many times. My parents are those considerate boomers. A generation that took the reins of our society when the century changed and we entered the 2000s. And the market noticed it. In 2001 it premiered on RTVE Tell me how it happened. Three years later it was republished he One, Two, Three…. In 2009, a phenomenon was launched that now seems timeless: I went to EGB. That same year, Antena 3 put on television Course of ’63. The look at the past does not only remain in Spain. The Police return for a new tour. Indy returns from the 80s to live an alien adventure in 2008. Guitar Hero puts us in the skin of the rock myths that had happened a decade or so before. Does anyone remember Guitar Hero Live? I doubt it and I think you already know the answer. And here I am, tasting at night the first seasons of There is no one who lives herewhile I watch in horror as my friends search for tickets to another Love The Tweenties and Villafrío de Abajo faces Villafrío de Arriba in another exciting final of the Grand Prix. I want to run away but the past catches me. That past that brings us back to Andy and Lucas but at least brings us back to the best days of Crash Bandicoot. A past from the day before yesterday. I laughed at my parents but here I am, drooling over the new Bugatti FKP Hommage. ELON MUSK VS JEFF BEZOS: STAR WARS Of necessarily unnecessary tributes and cars 20 years. What is 20 years? Enough, according to Frank Heyl, Bugatti Design Director, to “create what I consider the ideal and definitive Veyron.” What he’s talking about is the Bugatti FKP Hommage. We could say that it is the “last Veyron”. We could say that it is the final and last evolution of a legendary car. We could say it. If it were a Veyron. The Bugatti FKP Hommage is actually a Bugatti Chiron disguised as a Veyron. The hyper-luxury company, through its even more exclusive division Program Solitaire wanted to pay tribute to Ferdinand Karl Piëch, who was the grandson of Ferdinand Porsche and took the reins of the Volkswagen Group for almost a decade after having held all types of roles in the company. A key man in the company who was even more key for Bugatti. And Piëch was the one who gave the order to buy Bugatti and to make it a different brand, to give it back a glorious past, W16 via. “He was a man who saw the impossible not as an obstacle, but as a challenge. His vision for Bugatti was absolute: 1,000 horsepower, 400 km/h top speed, all-wheel drive, and refined enough to arrive at the opera in a tuxedo or a dress,” defines Hendrik Malinowski, General Director of Bugatti to Piëch. And to honor him, Bugatti has created a one offone of those unique units of your Bugatti Chiron. “The FKP Hommage celebrates this uncompromising pursuit of excellence, combining the timeless proportions of the original Veyron with two decades of engineering evolution,” reflects Malinowski about a luxury hypercar that comes with the latest evolution of the W16 engine and the 1,600 HP that the Bugatti Chiron Super Sport has. To resemble the original model, Bugatti’s most exclusive division has dressed the Chiron in the outfit that the Veyron would wear today. Play with the proportions to maintain the essence of a car of which only 450 units were manufactured. The request, of course, comes from a millionaire whose name we do not know. At least for now. But we can say something about him: he feels “melancholic sadness caused by the memory of a lost happiness.” This is how the RAE defines nostalgia. The question is what this loss has attracted a millionaire to convert one of the most technologically advanced cars in the world into another hypercar from just 20 years ago. What is the sense? Aren’t the 450 units of the original Bugatti Veyron unique because… they are unique? What is there to gain? Nothing. Since there is nothing to gain from updating an iPod when you have millions of iPods elder brother hand. It’s not a question of nostalgia. It’s a matter of the original product being there, just around the corner. We can’t miss him because he never left. You can’t long to go out partying singing Melendi at the top of your lungs because at less than 40 years old you are at the perfect age to continue going out partying and singing whatever you want at the top of your lungs. It’s okay for nostalgia to get to us. But at least it serves to give new life to the product. Unless it serves to make accessible an object of which there are few left, they are difficult to obtain or expensive to maintain. It’s funny that Renault brings back the Five in electrical format. And it makes sense that now the Twingo It also doesn’t have a combustion engine. Or what Renault brings the car back to life Turbo like an electric beast. As harsh as it may seem to a purist, even Ford Mustang Mach E It makes sense when it comes to bringing the driving sensations of a classic Mustang to an electric car. It is the same and, at the same time, very different. But the automobile market is beginning to be dragged into a well of nostalgia that contributes between little and nothing. He Lamborghini Countach LP 800-4 It is interesting as a design exercise because it updates a mythical model. This Bugatti FKP Hommage only repeats what is already known. The same is happening with the “serial” production of restomod. The trend of taking an old car and bringing it back to life by turning it into a modern car with a classic flavor makes sense … Read more

the new life of your Cable Car

by

This week, January 20, 2026, works started to dismantle one of the symbols of Madrid. They are, however, the first step to modernize it and adapt it to current security standards. With more than 50 years Behind them, the Madrid Cable Car is being taken down. The reason is a comprehensive renovation of the infrastructure. In fact, the cable car will remain alive but The iconic image will no longer return of the blue cabins supported by cables that seemed to flex too much. Because those cables with more than half a century behind them are being dismantled. The project includes a completely renovated cable car. Fewer cabins, faster journeys and, of course, the obligatory announcement that we will have the AI ​​monitoring possible incidents. It is a turning point in a story that was born at the end of the 60s. A cable car to nowhere Year 1969. Gento continued running on the Real Madrid wing and Gregorio “Hacha braba” Benito brought order to the center of the defense. But the team’s best years in Europe had passed. Gárate, Ufarte, Adelardo and Luis Aragonés would lead Atlético de Madrid to become League champion the following year and a few years later to brush with glory in Heysel before that great shot hit the net by one of those Germans with an unpronounceable name. The 60s gave way to a new decade and Madrid began to breathe a certain air of change without yet letting go of its most traditional signs of identity. Carlos Arias Navarro, then mayor of the city, turned the city upside down to get anywhere by car. Urban highways such as scalextric from Atocha and the proliferation of parking lots honored the rich Madrid tradition of drilling holes in the ground and always keep some work active. But, unlike motorized vehicles, in 1969 Madrid inaugurated a mass of iron that allowed people to fly above what would later become the M-30 and unite the Argüelles neighborhood with the Casa de Campo, then open to traffic and the classic setting for Sunday picnics. The plan seemed perfect to spend a day with the family eating tortillas away from the hustle and bustle. A completely isolated hill that, really, has no services at hand. What then led to building a cable car to nowhere in a city that was in full ferment and whose neighbors seemed eager for new plans? They count in elDiario.es that, really, the current Casa de Campo station was nothing more than an intermediate stop to get to the Amusement Park and the Zoo. That 1969, in fact, an attempt was made to inaugurate the first of these attractions together with the Cable Car, taking advantage of the festival of San Isidro, patron saint of the city, but the flying cabins had to wait because some neighbors tried to stop the project, claiming that the passage of these vehicles did not respect their privacy since they could see the interior of their houses. The Casa de Campo Cable Car station is linked to the Lake, the Amusement Park and the Zoo by roads that run through the interior of the urban park. But then you had to walk through pine trees to get to the recent Amusement Park, which is located just over a kilometer from the end of the cable car. To get to the Zoo it is necessary to double the distance. And the project contemplated joining both spaces with the cable car in a monorail that never came to fruition. If it had left, one of the city’s wealthy neighborhoods would be linked by air to two of the municipality’s great leisure attractions at that turn of the decade. The project, however, was stopped. Since 1969 it has been in operation with the same infrastructure, its cables have remained active for more than 50 years and it is estimated that it has transported more than eight million people. In 2022, a review temporarily paralyzed the facility when it was considered that it was not completely safe and in 2023 it was temporarily closed indefinitely. Now, the Madrid Cable Car seeks to write a new page in its history. This week the works for its dismantling began but a renovation project is already underway, so that the cabins can fly again for almost three kilometers above the Parque del Oeste and the Casa de Campo. They will do it with new cabins and renewed cables from Switzerland. With artificial intelligenceof course, which according to the Madrid City Council will help control incidents. Spaces that will weigh a ton with seats to transport a total of 10 people per trip. The challenge, they say from the City Council, has been to put new material in a space that was designed 60 years ago, they collect in The World. If everything goes ahead as planned, the flying cabins will return to the Madrid sky next year. They will do so after a five-year hiatus and almost 60 years after the first travelers covered that walk that, one day, should have linked the Argüelles neighborhood with the Madrid Zoo.

give it a second life on your Smart TV or PC

by

Let’s tell you How to give a second life to your old mini or micro systemso that you can reuse it, especially its speakers. Thus, if you have one at home or see one that is quite cheap second-hand, you should know that it may be better for you to reuse it than to buy a sound bar for your TV or speakers for your computer. Let’s start by telling you about the limitations you will have if you want to do this, such as limited audio formats or no network access. Then, we’ll tell you what you’ll need and how to proceed. These are the limitations The first limitation that you are going to find is in some audio formats. If you connect the mini system to a device such as a TV or computer, you can play almost all types of files, although you will not have support for Dolby Digital, DTS or Dolby AtmosFor example. What you will have is support for great audio quality, since the speakers are connected. The other limitation will be in the connectivity that your chain supports. The safest thing, being a few years old, is that you do not have support for USB-C or HDMI, and possibly not WiFi or Bluetooth support either. Mini chains that are a few years old will surely be limited to analog audio inputs by RCA-type coaxial cable, and it probably has two different inputs, one for the left speaker and the other for the right. The speakers you bring may also be connected to the micro system via a specific speaker cable. This is what you can do If your TV has support for RCA coaxial cables, there is no problem, because you just have to connect them to the micro system, and then the speakers to it. But not all TVs have this support, and of course your computer will not have it. For these cases, there are two solutions. The “easy” solution is to opt for a 3.5mm jack cable. Many TVs and some computers may have one of these connectors, the headphone jack for life, and many micro systems may also have an input to use them. Then, on the device you will have the option to output the audio to speakers or headphones. If your chain doesn’t support it, there are 3.5mm jack to RCA cable adapters, another good option. However, the best option is to buy a DACespecially if you want to reuse the mini system on a computer. These are small boxes that are responsible for converting digital audio into analog. This means that you can connect your computer or TV to the DAC via USB, and after the DAC the RCA cables come out. In fact, you can even use DACs as intermediaries for other PC speakers you have, because they usually improve the sound a lot. This is how I told you back in the day when I explained to you how to improve the sound of your computer. The negative part here is that DACs have a cost. I use a Fiio K7 with support for Hi-Res audio, and Its price is about 200 euros. You can also buy others for less than 100 or less than 50 euros in stores like Aliexpres, they will also work for you. There are many models and many prices, and it all depends on the use you want to give it. Some DACs even have Bluetooth support, which will add this connectivity to your micro system. Regardless of the method used, once you have connected your TV or computer to the micro system, then turn it on in the INPUT options choose the auxiliary or the one designated to input sound from another device you have connected. Reusing speakers is not easy Reusing only the speakers of a micro system without the device itself and its electronic part is a little more complicated. This is only possible if the speakers have passive filters for the frequency range already installed inside them. Almost all speakers are two or more ways, with at least one driver for treble and another for bass-midrange. For everything to sound correctly, the speakers need to send the corresponding frequency range to each driver through prior filtering. These filters can be passive with a filter made up of capacitors, resistors and coils, or electronically active. The normal thing is that the technology to be able to do this is within the microchain itselfso separate speakers sometimes won’t do.

By now we all know Gemini. Google AI is a fantastic tool that we can use for a ton of things: from writing down a recipe in Keep to getting ideas for giving a gift, to generating a Christmas card. We can download it through Google Play Store But there Android phones have an advantage, since Gemini is deeply and very naturally integrated into them. The best thing is how simple it is to activate this artificial intelligence assistant: All you have to do is press and hold the side button on your phone for a few seconds. and we will automatically be able to interact with Gemini (either by writing or speaking). Now, what exactly can this AI do for us? Let’s see it briefly. Gemini is a very useful tool that has no cost Gemini is a very versatile tool that, as we say, can carry out many tasks. Now, before moving on to it, it is worth mentioning two very important details that give even more value to Google’s AI. The first of them is that interacting with Gemini is very natural, so you don’t have to speak robotically for him to understand us. The other detail is also key: everything is done at no cost to the user. In addition to talking to Gemini directly (or writing, as we have said before), we cannot ignore the existence of Gemini Live. Thanks to this function, which arrived after the launch of this AI, we can activate the device’s camera to share visual information with GeminYo. It is very useful if, for example, we want this assistant to translate a poster in another language. We can also share screen with Gemini if ​​we wish. On a day-to-day basis, we can continually use Gemini to set alarms or create reminders. In fact, this Google assistant handles complex tasks very wellwhich simplifies everything a lot. The clearest example is that we can, with a single sentence and in a language that we would use to talk to a friend, ask Gemini to create a reminder for a doctor’s appointment and send a message with this information to our partner (among many other things). Finally, we must add to this cocktail the latest function that Gemini has received, so far, on mobile phones: Nano Banana. Thanks to this, we can generate images very precisely and use them for anything, whether to create a meme or to design a birthday greeting, for example. You have Android phones with direct access to Gemini on offer If you’re in the market for a new Android phone and looking for something that lets you access Gemini directly, you’re spoiled for choice. In fact, MediaMarkt has an active promotion with many of them on offeralthough you only have a few more days to take advantage of it. Below you have a selection of some very interesting ones.

TRAPPIST-1 was the most promising solar system to search for life. Now our joy is in a well

by

spent years searching for planets that could serve as a Earth 2in 2015 it happened. Thanks to the TRAPPIST telescope, we discovered an ultra-cool dwarf star which had three planets around it. They published the discovery in 2016, but a year later it was concrete that in the system there was a total of seven Earth-sized planets. It was clear: we had to continue investigating because there were options for one to harbor life. TRAPPIST-1 (because a way of naming the findings it is with the name of the telescope) became the “holy grail” of extraterrestrial life. The star is 40 light years away and three of its planets are estimated to be in the “habitable zone.” This is the segment with the ideal conditions for life to prosper. The initial enthusiasm was justified: they were small planets, they were not gas giantsand the star is so faint that the temperate zone of the system would favor those ideal conditions. Different climate models pointed out that only a small greenhouse effect would be needed for any of them to be able to house liquid water on their surface. but the same James Webb telescopewhat youit is giving us so much joyis the one who has unmounted almost completely the narrative of TRAPPIST-1 as a system in which to search for life. And in less than a decade, these planets have gone from being the most promising place in our cosmic block to being just another rocky exoplanet. James Webb lowering the soufflé There are multiple reasons why we look for extraterrestrial life. There are the philosophical reasons, the well-worn question of whether we are alone in the universe. Then the scientists, eager to find life to understand how much organisms can endure in other conditionsunderstand the origin and evolution of the universe and even compare ourselves with them. And the practices: experiment in other environments, get resources and to a new home. The telescopes with which we observe the system are good for that first exploration, but more recently the task was left in the hands of one of the most powerful we have, the James Webb Space Telescopeor JWST. The result of an international megaproject is not on earth, but on a satellite, which allows sharpness and detail of the observed objectives unattainable for terrestrial telescopes. And when we have pointed the JWST at TRAPPIST-1, the soufflé has been deflated. His work has focused on the inner planets, known as TRAPPIST-1b, c and d. The conclusion is thatTheir habitability is complicated due to the lack of atmosphere or one so “thin” that it would not protect the planet well against the star’s radiation, also implying surfaces so hot that they would not be compatible with life. Any hint of atmosphere that was initially observed is now practically ruled out. As we read in spacefrom the University of Arizona they comment that “based on the most recent work, the previously reported tentative hint of an atmosphere was likely just “noise” from the host star.” If the star itself gave us hope in the first place by not seeming to be a “killer” of planets, it has now moved to the other side of the spectrum. It is possible that this radiation bombardment allowed Extremophilic microbes will develop on those planets, but to do so they would have to have a denser atmosphere, something that JWST is not seeing. However, all is not lost. The Great Hope: TRAPPIST-1e Although d, c and d no longer look good, the great hope now falls on e, f and g. They are the planets located in a more temperate orbit, where the balance between radiation and atmospheric loss may be more conducive to having a denser atmosphere that allows life. Among them, astronomers consider TRAPPIST-1e to be the most promising. A few weeks ago, a article showed how JWST observed TRAPPIST-1e during four different transits at the time when the planet came closest to its star. The telescope’s near-infrared spectrograph recorded subtle changes in the light around it, which would indicate the presence of chemicals in the atmosphere. Their estimate is that the atmosphere is composed of a majority of nitrogen and methane, and not carbon dioxide as occurs on Venus or Mars. Now, is this the case or is it once again noise from the host star.” It is a possibility that they do not rule out, but as they comment, need more observations and analysis. The researchers are clear that “if TRAPPIST-1e has an atmosphere, it is habitable.” It is a bold statement, but the second part of the question is “is there an atmosphere?” For now, it remains an enigma, but the next step is what will allow researchers to rule out the planet as habitable or get excited again. What will they do? Observe the transit through the star of TRAPPIST-1e when it coincides with that of TRAPPIST-1b. This way, ‘e”s signal will not be contaminated with noise from its star and observers will be able to “separate what the star is doing from what is actually happening in the planet’s atmosphere. If it has one.” Therefore, there is a thread to hold on to, but it is better not to get too excited about a planet that is right here in the neighborhood of the infinite vastness of the universe.

Why 20°C “ice slush” changes our search for extraterrestrial life

by

Titan, the crown jewel of the moons of saturnjust gave us a slap of reality. For two decades, the official narrative of space exploration focused on what was hidden beneath its thick haze. a vast global ocean of liquid water. But now we know that we were wrong, or at least, it was not as we imagined. The study. Led by Flavio Petricca, from the Jet Propulsion Laboratory (JPL) from NASAand published this December 17, 2025 in Nature magazineproposes a radically different model: Titan does not have an interconnected ocean, but a dense, viscous layer of “slush ice” with pockets of trapped liquid water. The 15 hour lag. The Cassini probe ended its mission in 2017 crashing into Saturn, but its data remains a gold mine for physicists. Petricca’s team has therefore decided to reanalyze the probe’s Doppler data, that is, the changes in frequency in the radio signals generated by the moon’s gravity. But now with the most modern processing techniques that we have developed. The result of the analysis is a 15-hour lag in Titan’s tidal response. This means that when Saturn exerts its brutal force of gravity on Titan, the moon deforms as if stretched. In this way, if on its surface there would be pure waterthe response would be almost instantaneous as it is liquid. But what they saw is a 15-hour delay that indicated that the interior is highly viscous. What is it? The data collected suggests that the material on Titan behaves more like a pasty glacier or extremely dense slush. What seems ruled out is free-flowing water, where the existence of life in the future was already pointed out. A new Titan. With all the data that has been collected, it has been possible to completely define everything we knew about the internal geology of Saturn’s largest moon. Specifically, it is now known that the rock core has a radius of 2.26 km, and the layer that surrounds it is formed by high-pressure ice mixed with water. Although not everything has to be so cold, it also has hot water pockets due to the internal heat. This is what keeps liquid water lakes near the rock core at about 20ºC. The question of life. At first glance, eliminating a global ocean of liquid water may seem like a bad idea for astrobiologists who had hoped for life here. But for the members of this study, the opposite is true. In the new “slush” model, the liquid water in the pockets is in direct contact with the rock core. This is very important, as it allows the water to dissolve essential nutrients from the rose and also have a temperature of 20°C which is ideal for complex chemical reactions. But also, having a small size, all these components are more concentrated. Dragonfly. This discovery puts all the pressure on this NASA mission whose launch It is planned from 2028. Dragonfly is an octocopter designed to fly over the surface of Titan, but its most important instrument in this context is its seismometer. What was expected is that this mission would measure the tides of a deep ocean. Now their mission will be to confirm whether seismic waves propagate through this viscous “hail.” In the event that the characteristic vibrations are detected, we will have confirmed that Titan is the most promising chemical laboratory in our solar system.

In 1965, a notary bought an apartment of bare ownership from a 90-year-old owner. The old woman was already living her second life

by

In 1965, in the picturesque city of Arles, in the south of France, the notary André-François Raffray believed he had found a bargain to invest. Jeanne Calment, a 90-year-old widow and no heirs owner of a large apartment in the historic center of the town, was willing to reach an agreement to sell her housing in exchange for a life annuity and to be able to live in it until his death. With the statistical data in hand, the purchase of the apartment was going to be a bargain for the notary, so he did not hesitate to reach an agreement with the elderly owner. What the young notary did not expect is that it was going to be the worst deal of his life: the old woman had a bombproof geneticsor at least that’s what everyone thought. The deal was a bargain, but not for who it seemed The purchase agreement was simple in its approach: Raffray would pay 2,500 francs per month to Calment (an amount equivalent to about 380 euros per month). until the death of the old woman (who we remember was already 90 years old), after which the property would be fully his. This type of contract (known in France as traveler) is based on the bare property. This legal concept establishes that the buyer acquires the right to property without enjoy the usufruct until an uncertain event occurs, in this case the death of the saleswoman. That is, it is like a deferred purchase in which a certain immediate payment is established and the seller can use the property until his death. The buyer then takes possession of the property. Given this condition, the price of the investment is considerably lower than the market value, since it is not available immediately. That reduction in the initial price has shot the number of operations that have been growing at a double-digit rate since the pandemic. According to published data by Expansionin 2021, this type of operations grew by 22.6%, 23.7% in 2022 and 11.3% in 2023. For a 47-year-old buyer like Raffray, that seemed like a smart move and a very low-risk investment. In 1965 and with the life expectancy statistics much smaller than the current ones, Raffray assumed that Calment would live perhaps a few more years and that the total amount he would pay would be less than the market price of the apartment. A saleswoman with a lot of attachment to life However, what seemed like an operation with few unknowns turned into a financial nightmare for Raffray. Jeanne Calment, the elderly nonagenarian, not only lived beyond any reasonable expectation at that time, but his longevity surpassed all calculations. Officially, Calment died in 1997 at the age of 122 years and 164 days. as he collected The New York Times. That is why he entered the Guinness Book of Records as the oldest person recorded to date, It’s also bad luck for Raffay. Raffray, in turn, died in 1995 at the age of 77, 30 years after signing the contract with Calment. Until that moment, the notary had paid fees that, together, They far exceeded the value of the property. However, after his death, his widow was forced to continue with payments to Calment, because the obligation agreed in the annuity contract only disappeared with the death of Calment, not Raffray. There was no escape. The result was that Raffray’s family ended up spending much more money than it would have cost to buy the apartment through conventional methods, without ever moving in. Calment herself, with irony, even commented in an article for The New York Times that “in life, sometimes bad deals are made.” A life worth two As expected, such remarkable longevity did not go unnoticed by science and medicine, with much interest being shown in investigating the details about the life and habits de Calment to try to reveal their secret…and boy did they do it. In 2018, a research team formed by the Russian mathematician Nikolay Zak and the gerontologist Valery Novoselov proposed a radical hypothesis: Jeanne Calment could have died in 1934. The Calment who had signed the bare ownership contract with André-François Raffray could be Yvonne Marie Nicolle Calment, daughter of Jeanne Calment who, supposedly, had died of pleurisy on January 19, 1934. The hypothesis was that Yvonne would have impersonated his mother’s identity to avoid paying inheritance taxes. That artificially “extended” the longevity of his mother, who was actually living two lives under the same name. This theory was supported by discrepancies in ancient documents, such as differences in physical characteristics between historical records and by comparing photographs of Yvonne and the supposed elderly Calment. So it was not only a fraud to avoid paying taxes, Raffay was also victim of deception. However, there is no scientific consensus on this version. Subsequent research by a team of Swiss and French demographers and historians, published in it Journal of Gerontologythey discard the hypothesis of fraud and maintain that, statistically, Calment could live to be 122 years old.

We knew almost nothing about the “black box” of life, the initial moment of fertilization: that is over

by

In biology, human development, from the fertilization of an egg to the formation of the complete baby, has a large area called ‘black box’because we don’t know what happens there. We have a lot of data about what happens in the first days after fertilization and also during the last months thanks to ultrasounds. Worse, there is an area between the second and fourth weeks of development that is terra incognita. The ethics. It is without a doubt the great wall of developmental biology right now, since to see what happens to an embryo in these weeks we would have to have it in a culture dish for more than 14 days. But this is something that ethics does not allow, since after those days the embryo must be inside a uterus or destroyed. The change. Now science is working to find exactly how to see the embryo in this time window, and the Chinese Academy of Sciences and the Pompeu Fabra University of Barcelona achieved it. Specifically, it has achieved cultivate macaque embryoids which are embryo models derived from stem cells until day 25. In this way, processes that until now were hidden have emerged. A team of researchers from the Chinese Academy of Sciences and the Pompeu Fabra University of Barcelona has managed to cultivate macaque embryoids (embryo models derived from stem cells) until day 25, revealing processes that until now remained hidden. And this has already given us data about how our body is formed. Gastrulation. Lewis Wolpert, a famous biologistused to say that “the most important moment in your life is not birth, nor marriage, nor death, but gastrulation.” And he was right. To understand this importance, you must know that during gastrulation the embryo stops being a simple sphere of equal cells and transforms into a complex structure with three different layers that will give rise to all the organs of the body. But it is also essential to be able to define the axes of the body, that is, knowing where the head will be, the tail and what is right and left. Something that until now was impossible to see because previous models of primate embryos ended up collapsing after day 17. The solution. The research has therefore used a new system of 3D suspension culture which has enabled macaque embryonic stem cells to self-organize and develop complex structures until day 25 outside the uterus. What they have seen. What researchers have observed in these “embryoids” is fascinating because of its similarity to natural embryos. As detailed in the paper from Nature, these models have recapitulated key events of the late gastrulation. Among this, the formation of the central nervous system stands out, the precursor of the digestive system, the first blood cells or even those that in the future will give rise to eggs and sperm. The most surprising thing is that the transcriptomic analysis (the study of which genes are active cell by cell) revealed that differentiation trajectories were similar to those found in natural monkey embryos during this stage. At last. This means that we have, for the first time, a reliable simulator to study human development. Since we share a large part of our biology with macaques, this model allows us to investigate the causes of abortions early spontaneous and congenital malformations without crossing the ethical red lines of experimentation with human embryos. They are not real embryos. This is something fundamental for the limits that ethics imposes on us that we mentioned at the beginning. What has been cultured in this case are not real embryos, but models derived from stem cells where neither eggs nor sperm were involved. This has the aspect that it can never become a viable living being if it is implanted in a uterus and its usefulness is limited only to laboratories to analyze how we are developing and revealing critical points where an embryo can be aborted.

We already have the missing ingredient to explain the origin of life

What the mission OSIRIS-REx brought back to Earth in his capsule after being perched on the asteroid Bennu It could be very enriching, but the truth is that it has exceeded all our expectations. And in the past we have already been surprised to find water or carbon in space, but now NASA has confirmed than what has been seen on this asteroid: Bennu contains sugars essential for life as we know it. But not only that, among the grains of dust and rock, researchers have come across something they did not expect: a mysterious substance that they have already dubbed ‘space gum’. The discovery. After a long time analyzing the materials extracted by this probe, the results have finally been released to a published study in Nature Geoscience led by Yoshihiro Furukawa from Tohoku University (Japan) and which undoubtedly marks a milestone in astrobiology. From a sample of just 603 milligrams of Bennu dust, the team was able to detect a variety of sugars that are biologically significant, such as glucose. This marks something historic since it is the first time that this sugar that we know so well has been identified in a pristine extraterrestrial sample. But this has not only been the important thing, but also samples of ribose which is an essential component of RNA, which is responsible for transporting genetic information in human organisms and which undoubtedly It became popular during the COVID pandemic. Its importance. Until now we had seen signs of these samples in meteorites, but there was always the shadow of land pollution upon impact. Now this doubt disappears since the samples arrived sealed. What is undoubtedly important is that the joint presence of these sugars suggests that they were synthesized by abiotic processes (without life) inside the asteroid, probably through chemical reactions in the presence of water at the dawn of the solar system. Something that would be essential to be able to generate life. Space gum. If sugars are the “hard” science news, what has captured most of our attention is what Danny Glavin, a mission co-investigator at the Goddard Space Flight Center, describes as “space gum.” The analyzes revealed a unique polymeric material, a kind of complex, sticky substance that doesn’t fit the standard minerals we’re used to. That is why its composition is now under study and its presence indicates that Bennu is not only a pile of rubble, but a chemical laboratory that is capable of create organic macromolecules that we have living beings inside us. In addition to this “gum” and sugars, the samples contained star dust that is older than our own Sun, survivors of ancient supernovae that were trapped in the asteroid’s matrix. A ‘complete kit’. With this announcement, the Bennu puzzle seems to be complete since amino acids have been found that are essential for proteins, bases to form DNA, carboxylic acids and now sugars to give energy and structure to RNA. This strongly supports the hypothesis that carbon-rich asteroids, like Bennu, acted as “cosmic delivery boys” during the late intense bombardment, seeding the early Earth with all the ingredients necessary for the life we ​​are now enjoying to emerge. It is literally an asteroid that carries all the ingredients for life as we know it. A look at the past. The stability of compounds like glucose and xylose in these samples, along with the surprising presence of ribose (which is typically very unstable), tells us that Bennu’s parent body had very specific water activity and chemical conditions shortly after the solar system formed. As confirms NASA itselfwe are facing the strongest evidence that the building blocks of biology are not a miracle exclusive to Earth, but rather common products of the chemistry of the universe.
