an AI that follows you from one device to another without losing track

by

Motorola has presented its first ‘fold’ type foldable at Lenovo Tech World 2026, an ultra-premium line called Signature and, above all, Motorola Qira: an AI platform (they call it “personal ambient intelligence”) shared with its parent company Lenovo that works on smartphones, tablets and computers, maintaining the context between all of them. Why is it important. Lenovo and Motorola’s commitment to AI is something different: that AI is the same on all your devices. It sounds obvious, but it is not so obvious. Qira maintains the context, the data and the conversation. You start something on your mobile in the morning and continue it on your laptop in the afternoon without repeating anything. The move attacks today’s biggest productivity problem: switching between apps and devices often breaks your workflow. Each change involves explaining again what you need. Between the lines. This is clearly a response from Lenovo to the strengths of the Apple ecosystem. Apple has much of its advantage in syncing between iPhone, iPad and Mac through proprietary software, and now Lenovo is trying to replicate it with AI as the common thread. The difference is in the execution. Apple controls hardware and software. Lenovo depends on Android and Windows, third-party systems. Your only asset to create that fluid experience is for AI to be the glue. In detail. Qira is not just another chatbot. It is an “ambient intelligence” (the naming is from Motorola) integrated at the operating system level, always present without having to open an app. Summoned with “Hey Qira”, with a dedicated key or by tapping the permanent item on the screen. Works even offline using local AI. The proposal is based on three attributes: Presence: It’s there, it can proactively suggest things or wait for you to call it. Actions: Execute tasks between applications and devices without having to manage each step. Perception: Build a unified knowledge base (with your consent) that includes your interactions, memories and documents across all devices. The use cases. Lenovo and Motorola have defined specific functions where Qira should shine: “Next Step” suggests actions based on what you’re doing and helps you switch devices without losing track. “Write for me” composes emails, documents or messages directly where you work, adapting to your tone. “Catch me up” summarizes what happened while you were away and helps you get back to tasks. “Pay Attention” transcribes and translates meetings in real time, captures key points and generates summaries. privacy. Processing occurs primarily on the device to keep data local. Cloud services are optional and require explicit consent. Lenovo insists that Qira never collects data without user permission. The context. No manufacturer has yet managed to make their devices “talk to each other” naturally using AI. Samsung has tried it with Galaxy AIGoogle with Gemini and Microsoft with Copilot. Everyone stumbles upon the same thing: their assistants don’t remember what you did on another device. They are great on one device but they stop being great when we switch from one to another. The specific applications do shine there (ChatGPT, Gemini, Claude, Grok…), but they do not have the system-level integration that Qira, Galaxy AI and company do propose. Qira unifies under one name the dispersed solutions that have arrived until now: motorcycle ai (the lower case imperative is a Motorola thing), Lenovo AI NowCreator Zone and Learning Zone. The platform integrates collaborations with Microsoft 365, Copilot, Qualcomm, Intel, Perplexity and Google. Motorola does not have a large share in the premium segment, if Qira works well it could be an argument to attract customers. Qira will arrive in the first quarter of 2026 on “select” Lenovo devices and then on compatible Motorola phones. They have not yet communicated the list of models that will receive it. The approach is pragmatic: better to integrate what already works than to compete with OpenAI or Google in the creation of foundational models where they would hardly be able to scratch anything. Qira is not its own model, but a platform that connects different AI services depending on the task. Go deeper. Beyond Qira, there is a strategic reading: Lenovo is trying to become the reference manufacturer for those who do not want Apple but do not want to rely only on Google. It is a difficult space to fill. They all failed because creating ecosystems requires years of investment, gaining committed developers, and reaching users willing to change their habits. Lenovo has financial muscle and Motorola retains brand prestige. But you’ll need Qira to really work. In Xataka | The technology industry has been searching for the “next smartphone” for a decade.

Boeing wanted to get back on track with Starliner after its most difficult year. The contract with NASA just changed in a key point

by

For years, Starliner was presented as Boeing’s opportunity to aspire to a leading role in American manned flights, in a scenario in which SpaceX I moved faster with Dragon. The contract signed with NASA in 2014 It represented that opportunity: six manned flights and an open door to a new cycle of missions. Eleven years later, the situation is different. That agreement has been adjusted and the next mission has become an exam without people on board. That agreement placed Starliner within the program with which the US space agency sought to guarantee two different US vehicles to the International Space Station. The idea was clear: have more than one capsule capable of transporting astronauts, long-term planning and autonomy in low orbit. That document established that, once the ship was certified, Boeing would operate six manned flights for regular rotations. All this with an eye on the station’s deadline, scheduled for 2030. A shortened contract, by mutual agreement. NASA and Boeing have decided to modify the conditions of the original agreement and reduce the number of guaranteed flights. Instead of the six manned missions planned after certification, the new scenario includes a mission without astronauts, intended to validate the system, and up to three crew rotations. In addition, there are two optional flights that NASA can activate depending on its mission needs. This review also reduces the value of the contract, which goes from $4.5 billion to $3.732 million, after deducting $768 million. Starliner-1 changes roles. This mission without astronauts has a name: Starliner-1, and it has become a key piece of the system validation plan. NASA will use it to send cargo to the International Space Station and verify, in real conditions, that the changes introduced after the manned flight in 2024 offer sufficient guarantees. The target date remains no earlier than April 2026, provided the spacecraft successfully completes testing, certification and pre-launch preparation. A history of setbacks: The first warning came with flight OFT-1 in December 2019, when some problems prevented for Starliner to complete the planned profile and approach the International Space Station. The mission had to be terminated early. In 2022, the OFT-2 flight managed to reach the station, but problems appeared in several thrusters. Two years later, during the first manned flight, several thrusters failed again on approachwhich led NASA to order the return of the ship without the astronauts. NASA and Boeing engineers inspect the Starliner spacecraft after landing in White Sands, New Mexico, during the OFT-2 orbital test in May 2022 When NASA decided that Starliner would not bring Butch Wilmore and Suni Williams back, they both extended their stay on the International Space Station much longer than planned. In total it was nine months, until the agency scheduled a Dragon flight with two fewer astronauts than usual to have enough space. That landing, in March 2025, allowed the return to be completed and confirmed that the evaluation process on Starliner was still open after the 2024 manned flight. Meanwhile, Dragon. In parallel, Dragon began operating with astronauts in 2020 and was progressively incorporated into NASA’s regular planning. Since then, the SpaceX capsule has covered the planned rotations within the Commercial Crew Program, becoming the vehicle regularly used to access the International Space Station. In August 2025, the Crew-11 mission was completed, and Crew-12 is scheduled for February 2026. NASA has booked additional flights with Dragon until the station’s operational end, scheduled for 2030. Less flights, less income, more pressure. The contract modification also means a change in Boeing’s position within the program. The reduction of the total value to 3,732 million dollars implies 768 million dollars less compared to the original figure, with fewer guaranteed flights and a greater weight of optional missions. According to Reutersthe company has invested more than $2 billion since 2016 in this development, which adds relevance to Starliner’s performance in upcoming flights. Despite this, Boeing says it remains committed to the program. Redundancy against the clock. For NASA, Starliner remains relevant because the agency wants two independent systems that can transport astronauts to the International Space Station. Steve Stich, head of the Commercial Crew Program, summed it up by pointing out that the plan involves certifying the ship in 2026, scheduling its first manned rotation when it is ready and coordinating future flights according to the operational needs of the station, which will remain active until 2030. Maintaining this double capacity is key so that the agency does not depend exclusively on a single vehicle. What happens from now on will depend on the outcome of the next flights. If the system manages to be certified in 2026, Starliner can still participate in up to three crewed rotations, with two additional options subject to NASA decision. Boeing maintains its commitment and suggests that the ship could have a place in commercial projects after the end of the International Space Station, although these scenarios are yet to be defined. The opportunity has not disappeared, but it no longer looks as much like the one signed in 2014.

stuck on a dead end track

by

In September, the future European fighter in which Spain participates began to disfigure publicly. Already in November, in a new twist of script, the European fighter began to point to something else. The latest? The Future Combat Air System project, FCAShas ceased to be solely an industrial and technological program to become an uncomfortable mirror of Europe’s ambition (and limitations). The plane is literally at a dead end. A symbol that wobbles. Those ambitions have was staged these days in the figure of Emmanuel Macron and Friedrich Merz, and the Europe they aspire to. Both leaders have spent weeks redoubling a speech that insists on strategic autonomy, digital sovereignty and its own military capacity, a message that is amplified in a continent shaken by uncertainty about the American commitment and by the aggressiveness of a Kremlin that has returned conventional war to the heart of Europe. In this context, the FCAS had been conceived as the emblem of a continent capable of compete with the F-35 American, to secure replacements for the Rafale and Eurofighter that are beginning to approach their operational end, and to demonstrate that Europe can still lead technological revolutions in defense. Reality blow. But the rindustrial and political reality surrounding the program contradicts official rhetoric. Eight years after its presentation, FCAS is accumulating delays, internal disputes and an atmosphere of mistrust that turns each negotiation into a slow erosion of expectations, forcing us to wonder if this plane of 100,000 million of euros has not become a failed test before even taking off. The blockages that show the seams. Behind the common façade, France and Germany carry structural rivalries that become especially visible when they must cooperate in a field as sensitive as combat aviation. Dassault and Airbus, the giants called to work side by side, have been exchanging reproaches. Eric Trappier, head of Dassault, has never hidden his refusal to give up leadership in design, nor has he hidden his disdain for German technical capacity in areas considered critical. From the other side, Airbus accuses Dassault of protect historical privileges incompatible with a modern multinational project. The international success of the Rafale, unexpectedly converted into a symbol of independence compared to the F-35, has further strengthened the French position and has strained the distribution of burdens and responsibilities. None of these frictions are new, but they are have become more corrosive at a time when cooperation is no longer just desirable, but necessary. What should have been an alliance between equals has led to what analysts describe as a marriage of convenience full of suspicions, in which every tactile decision on intellectual property, industrial distribution or technological transfer becomes a clash of corporate cultures. The political factor. Added to the industrial complexity is the political vulnerability of its promoters. Macron, cornered by an internal budget crisis and by the prospect of a 2027 that could hand power to the far right, has lost the ability to impose rhythms or guarantees in long-term projects. Merz, for his part, deals with a economy that seeks to reinvent itself and with a rise of the far right which forces careful internal calibrations, but unlike France, Germany yes it has resources: Its defense budget is heading towards a doubling that transforms Berlin into the dominant partner in financial terms. This asymmetry introduces a power imbalance that irritates both Paris and the industrial partners involved. Believe or not believe. This being the case, cooperation fundamentally requires trust, but that trust is precisely the resource that is most scarce. Without clear leadership, without a sustained common vision and without an architecture that credibly distributes risks and benefits, FCAS has become a hidden battle for influence rather than a joint project. What no one says, but everyone thinks. They remembered on Bloomberg that, as delays increase, hypotheses begin to emerge that would have been unthinkable just a few years ago. It we comment a few weeks ago, one way is to transform FCAS into an umbrella digital interoperability that allows each country to build its own plane, all connected by a common data system. This path would allow Dassault to follow a sovereign path, while Airbus would concentrate its efforts on mission systems, companion drones and data fusion. But there is more. Another alternative, more ambitious and politically riskier, would be to abandon the national distribution of work, which assigns tasks by flag, and move to a distribution by industrial skillsrewarding whoever can make each piece better and faster. This last option is what specialists have been asking for for years, but it is also the one that clashes head-on with the electoral incentives of each government. European defense remains organized to maximize benefits at the national levelnot common efficiency, and as long as this does not change, they will repeat the same blocking patterns. Without deep reform, FCAS risks becoming another example of ambition being suffocated by domestic politics. Consequences of failure. He FCAS failure It would be more than the collapse of an industrial project. It would represent a devastating message for a continent seeking to demonstrate that it can guarantee its security without completely depending on the United States. While the F-35 changes balances in the Middle East and while Europe watches, almost daily, how Russian drones penetrate western airspacethe world is moving towards a technologically different war. The countries that lead this transition (from autonomous swarms to sixth generation platforms) will determine the correlation of power of the 21st century. Giving up on FCAS would mean accepting that Europe is late, that it is not prepared for the industrial leaps that modern conflict requires and that, despite the rhetoric of strategic autonomy, it continues to depend from external suppliers for their critical capabilities. This dependence is the same one that Macron and Merz say they want to overcome, although the failure to fulfill their own projects pushes them, step by step, towards it. Between two waters. If you will, the outcome from FCAS It will be a … Read more

Canopo’s decree is one of the greatest mysteries to solve the ancient Egypt. And finally we have a key track to understand it

by

Egyptologists and especially those scholars dedicated to the study of hieroglyphs and The Ptolemaic dynasty They are in luck. And rightly. A team of archaeologists has located in the site of Tell el-Faran´inin the city of The Husseiniya (Sharqia), an unparalleled treasure in the last century and a half. Not because of the materials with which it is manufactured or its lavishness. No. The key is what he says, how he says it and above all what he does not say. What experts have found is neither more nor less than a famous stone trail Canopo decree. Of course, a very special. What is Canopo’s decree? A Egyptian decree promulgated by the king Ptolemy III Evergetes on a deck of 238 AC, in full Ptolomeics dynasty. The document was written after the high priests met in the city of Canopusto the east of Alexandria, to honor the monarch, his wife Berenice and the little daughter of both, who died by those same dates. It may sound boring, but the decree has been fascinating the Egyptologists. The text exalts the figure of the monarchs (“The benevolent gods”), their donations, campaigns and veneration in the temples. Also of more practical issues, such as the decision to lower taxes those years in which crops did not receive enough water from the Nile, or the creation of a new priestly range and a religious holiday. Another of the ads that it collects is the deification of the deceased daughter of Ptolemy III Evergetes and Berenice, which was called as her mother. Does it say anything else? Yes. Among other issues, the introduction of a new system of leap years which would add an extra day every four years to adjust it to religious rituals. Ptolemy III wanted that additional day to commemorate him and his wife, but the idea He didn’t finish curdling. Today it reminds us how advanced Egyptian astronomy was and how it advanced to Julian calendarintroduced by Julio César in the 46 AC replacing the Roman. Beyond what he says, the decree is valuable for how he says it. The document makes it clear that its content should be expressed in stelae that mixed three different writing systems: Egyptian hieroglyphs, The demotic and The Greek Koiné. The copies should also be distributed among the main temples for the edict to reach every corner of the kingdom. When in the nineteenth century the archaeologist Karl Richard Lepsius He discovered one of those specimens in Tanis, he found a valuable help to decipher the hieroglyphs. So or even more than Rosetta stone. How is the new wake? Of sandstone, 127.5 centimeters high and 83 wide, with a thickness of 48. Its upper part is rounded and, in addition to the registration of the central section, distributed over 30 hieroglyph lines carved in relief, the stone shows some interesting decorations. The design is crowned by a large winged solar disk flanked by two royal cobras that show the white and red crowns of Egypt, symbol of the union of the two lands. In the center, an inscription stands out in which “Di-Ank” can be read, a message that could be translated as “the one that gives life.” Why does the finding matter? Because the copies of Canopo decree do not abound. Or at least we have not found them. As remember The Ministry of Tourism and Antiquities of Egypt, the wake found in Tell el-Faran´in will join the other six known and unearthed versions inKom el-hisn, Tanis either Tell enough. Some are complete. Another are just fragments. “This discovery is considered the most significant of its kind in more than 150 years, since since then no new and complete version of the decree has been found,” Underline. Does it differ in something? Yes. And that is one of the reasons why the wake recovered in Tell el-Faran´in has generated so much interest. Although the decree of Ptolemy III made it clear that it should be captured in stelae that combined the three writing systems (hieroglyphic, demotic and Greek), the specimen we just found shows only one. This was confirmed by Mohamed Ismail Khaled, of the Supreme Council of Antiquities, who Clarify that the wake is written “entirely in hieroglyphs”, which differentiates it from other previous trilingual versions. What is it for? Beyond the obvious historical, archaeological and patrimonial value of the finding, Tell el-Faran´in wake has a key utility. From the outset, it has served the Egyptian Minister of Antiquities, Sherif Fathy, to breastfeed for the “continuous achievements” of the archaeological missions of the country and the “support” of the government to the excavation campaigns, something that feels especially good in full controversy by the Tourist megaproject of the Sinai. Political issues apart, scholars are relying on squeezing the content of the wake. The authorities expect them to help them expand their knowledge about the real and religious documents of the Ptolemaic era and “enrich” the understanding of that historical period. If something has aroused interest, it is, however, that the stone includes a single writing system, which seems an exception to the norm that includes the decree. “Open new horizons for our understanding of the language and provides additional information about Ptolemaic decrees, as well as about real and religious ceremonial systems,” Add the government.

The body warns of Alzheimer’s long before the brain. The track is in the intestine

by

Keep ‘healthy’ The bacteria we have in the intestine It is more important than we can think. During the last decade there are many voices that have arisen pointing to the relationship between our microbiota and other parts of our body. Now, a study has given light on the amazing connection that exists between digestive and metabolic health and the risk of developing diseases neurodegenerative as Alzheimer’s either Parkinson. A study that has used data of all kinds. Research, published in Science Advances, Not only identifies specific disorders that increase the risk of these diseases, but also demonstrates that these signals can be detected up to 15 years before neurological diagnosis, opening a new and promising via for Early detection and prevention. The work, which analyzed the clinical, genetic and proteomic data of hundreds of thousands of biobancos such as the UK Biobank, Finngen and Sail, is the most extensive of its kind and reinforces the importance of called intestine-corebro axisthe complex communication network that connects our digestive system with the central nervous. Digestive disorders and Alzheimer’s. The researchers analyzed the association of 155 digestive, endocrine, metabolic and nutritional disorders with the future risk of Alzheimer and Parkinson. The results are revealing. For Alzheimer’s, it was found that previous diagnoses of the following conditions significantly increased the risk: Gastritis and duodenitis Esophageal reflux disease (esophagitis) Diabetes (all types) Vitamin D deficiency Electrolyte disorders and acid-base balance Functional intestinal disorders (such as irritable intestine syndrome) There are also warning signs for Parkinson. A disease that is also neurodegenerative and is iconicly characterized with a constant tremor, among many other signs. In this case, the pathologies that could be an alert sign to generate this disease were: Dyspepsia (indigestion) Diabetes (dependent and independent of insulin) Functional intestinal disorders The importance of being a stratified study. This means that the data were divided into windows from 1 to 5, 5 to 10 and 10 to 15 years before diagnosis. This is something really important, since researchers could confirm the theory that the increase in risk is not something that happens just after the appearance of the first neurological symptoms, but it is a process that is created over more than a decade. For example, a diagnosis of non -insulin -dependent diabetes between 10 and 15 years before was associated with a 71% greater risk of developing Alzheimer’s. The importance of an early diagnosis. And it is that diagnosing a neurodegenerative disease so in advance is the best asset we have to avoid its most unwanted effects. Right now Alzheimer is an incurable disease, but There are drugs that stop the disease. From here lies the importance of having an early diagnosis, since the sooner the timely treatment begins, the more difficult it will be to progress to the worst stages. It also has protection functions. Curiously, it has been seen that a hemorrhoid diagnosis was associated with a lower risk of Alzheimer’s. The authors speculate that this could be due to a survival bias: the serious conditions that are sometimes associated with hemorrhoids could have a higher mortality rate, which would reduce the probability that these patients live enough to be diagnosed with Alzheimer’s. Genetics or lifestyle? One of the most counterintuitive findings in the study has to do with genetics. The researchers calculated the polygenic risk scores (PRS), which is a measure of genetic predisposition to a disease, and compared them. They discovered that patients who developed Alzheimer’s or Parkinson and also had one of these digestive or metabolic disorders, on average, had a lower genetic risk score than those who developed the neurological disease in isolation. Inheritance does not matter so much. These results can translate into that the person with intestinal comorbidity, environmental and lifestyle factors They play a much more decisive role in the development of Alzheimer’s or Parkinson’s than the genetic inheritance itself. It is the evidence that we needed to reinforce the idea that the disease is not only in our genetic material, but that the environment and our decisions can intervene in its development. Towards a multimodal predictive model. The true qualitative leap of the study is the creation of a multimodal prediction model. Instead of based on a single type of data, scientists combined four pillars of information: clinical, genetic, proteomic data (with the analysis of 1,463 biomarkers) and demographic. The result was a model with a predictive capacity much higher than that of any individual paradigm. For Alzheimer’s, the combined model reached a 0.90 precision (AUC), a very high level for this type of predictions. It is interesting to note that the model that excluded clinical data, but maintained genetics, proteomics and demography, obtained almost identical precision (0.89), which suggests that blood biomarkers already capture much of the biological information that underlies clinical diagnoses. A diagnosis based on an analytical. Among the most influential biomarkers were found GLIAL FIBRARRARARY ACID PREIIN (GFAP) and the light chain neurofilament (NFL), both known as indicators of neuronal damage, which validates the biological robustness of the model. This approach demonstrates that the integration of different “omics” (genomic, proteomic) with clinical data is the way to follow for truly early and personalized detection, long before cognitive symptoms or irreversible motors appear. The team has even developed an interactive web platform so that other researchers can explore the results, promoting transparency and reproducibility.

China’s sky has just given us another track of its air ambition. A plane so radical that costs to guess its function

by

In the month of June Some images In the sky of China they went viral. The future furtive hunt for the nation appeared on the scene, The J-36and did it clearly leaving behind the clues and indications of a technical ambition rather than remarkable. Now, a month later, another figure has just appeared thundering the sky of Beijing. But this time it seems something else. A new device without a tail. Yeah, Recent images They have revealed the existence of a new furtive combat apparatus in the test phase in China, whose Design without tail You have aroused doubts about whether it is a man -generated manned plane or an advanced combat drone with functions From “Loyal Wingman”. Although it is not clear if the aircraft has a cabin, the model presents features of a design of great sizepossibly manned, with wide fuselage and significant fuel capacity and internal armament. The absence of cola vertical surfaces, the wings in configuration with a “W” -shaped escape edge and the integration of twin air inputs suggest an effort by Maximize rankiness. The double wheel front landing train and the data probe in the Morro point to an early test of tests, but also to a considerable weight design, even suitable for aircraft carrier operations. Odds. The fact that the device shows similar characteristics TO CHENGDU J-36but in a seemingly more compact format, it has led to speculate that it could be a direct competitor of the SHENYANG J-XDS/J-50as part of the struggle between the two main aeronautical houses of China. This hypothesis makes sense if it is considered that The J-36due to its size and conception, it does not compete in the same segment as the J-XDs. A derivative smaller, bimotor And optimized as more traditional mission hunting, would fit in Chengdu plans to diversify its range and rival Shenyang. The possibility that it is an optimized design is also considered For aircraft carrier or of a sixth generation hunt in medium version, although the scale of the device cannot be determined with the available images. Another image of the new device The alternative of a drone. Another interpretation indicates that this model could be one of several Chinese projects inspired by the American program of Collaborative combat aircraft (CCA). In that case, it would not be a manned plane but A high performance UCAV With advanced autonomy, designed both to operate together with manned fighters and for independent long -range missions. Experts like Andreas Rupprecht They have identified Similarities and differences with other designs “without a tail” detected recently, which reinforces the idea that China simultaneously develops multiple prototypes of furtive drones, informally known as “tea cups”in contrast to the manned fighters nicknamed “teapots”. The diversity of configurations (from Deltas modified to diamond wings and mixed configurations) suggests that the country experiments with several solutions before consolidating an operational fleet. Tests and indications. Plus: The revelation of this new plane coincides with satellite images taken in Yangfangnear Beijing, where at least five different designs of CCA drones were identified in preparation for the September 3 parade, on the occasion of the 80th anniversary of the victory over Japan in World War II. Among them you can see models 9 to 12 meters long, some without tail and others with more traditional configurations, partially camouflaged under canvases. The same base also houses Balistic and UCAVS missile launches already known, such as the GJ-11 Sharp Swordwhich reinforces the idea that the parade will publicly exhibit the new generation of unmanned combat systems. In parallel, another large fuselage appeared in Shenyang’s plantwith a modified Delta design, which adds more unknowns about the different ongoing programs. China vs.euu. It We have counted. The accelerated rhythm of the Chinese military aerospace industry It is undeniableand this new plane (whether or not manned) demonstrates Beijing’s ability to generate Strategic surprise In a recurring way. In this field, the comparison with Washington is inevitable: the American Air Force currently develops The YFQ-42a of General Atomics and YFQ-44a de Andurilwith flights planned for next year and with an approach based on iterative design and deployment cycles. China seems to be emulating this modelmultiplying prototypes and moving rapidly in autonomy, AI and swarm capabilities. The biplaza fighters J-20s They have been profiled as drone swarm controllers, while early alert planes KJ-500 either H-6 bombers They are intended to become key nodes of this manned-nokened collaborative network. The strategic importance. Although it is not yet known with certainty if the new plane is a sixth generation hunting or An advanced UCAVthe truth is that China is developing a Range of platforms ranging from disposable drones to long -range pools. If it is confirmed that it is an unmanned plane, the model could constitute a more powerful and autonomous version than The GJ-11with the ability to accompany To the futures H-20, J-36 and H-6 in Missions of great action radius. If instead it was a new manned fighter, industrial rivalry would be consolidated Between Shenyang and Chengdu and would reinforce China’s jump towards a diversified fleet of sixth generation. In both cases, the message is clear: Beijing accelerate your advance In air combat technologies and seeks to reduce the gap with the West, positioning itself as a power capable of combining furtive aviation, AI and collaborative operations in a single air war ecosystem of the future.

Ozempic and blindness, we have been on the track of an extremely rare adverse effect for months. Now the AEMPS has taken a step forward

by

A few days ago the The United Kingdom warned on an unexpected effect associated with the use of Ozempic and treatments based on the same principle, the phenomenon of Ozempic Babies. Now the Spanish Agency for Medicines and Health Products (AEMPS) has also issued a statement but this time as a consequence of a very different effect. Adverse reaction. This week the AEMPS, the agency in charge of ensuring that the drugs meet the required standards, has issued A statement To warn of a very uncommon ocular adverse reaction “associated with treatments based on the semaglutida, the active compound of drugs such as Ozempic, Rybelsus or Wegovy. The notice occurs after the Committee for the Risk Assessment in Pharmacovigilance (PRAC) of the European Medication Agency (EMA) reviewed the risk of developing an ocular condition called Niana, which can cause loss of sudden vision. While the agency affects that the frequency of appearance of this type of eye problems is “very low”, it recommends that a sudden loss of vision is carried out an ophthanmological examination for Evaluate the possibility to interrupt the treatment. Noiana. Noiana is an acronym that refers to calls Previous ischemic optical neuropathiesNaion in English. These ailments are caused For the infarction of the optic nerve head. In other words, blood does not reach this eye region and a loss of vision occurs, which is typically fast but painless. It is an unknown and infrequent disease, not only in the context of those who follow a trailer treatment: its prevalence in the general population is approximately 10 cases per 100,000 inhabitants. A year on track. A year agoa study I found indications of the relationship between the treatments of Semaglutida and Niana. Indications such as those that gave rise to the evaluation by the Pract. The Committee reviewed clinical and preclinical essay data together with suspicion of adverse reactions, explains the AEMPS. This work resulted in the conclusion that trailer treatment can be associated with a risk of developing this disorder but indicate that with a very low frequency. The AEMPS speaks of “an increase in the risk of developing Niana of approximately double compared to people not exposed to this treatment. This corresponds to an additional case of NOIANA for every 10,000 patients treated with semagglutida for a year.” And what about the “other ozempic”? The AEMPS statement focuses on the drug -based drugs such as Ozempic, Rybelsus and Wegovy but does not indicate whether similar effects have been detected on similar treatments such as those based on the tirzepatida, such as Zepbound and Mounjaro. A medication with side effects. Like any drug, the semaglutida has a series of Contraindications and side effects. It should be remembered in this sense that the success of drugs such as Ozempic began when it was observed that this treatment against diabetes made those who followed it lost weight.

We are increasingly sure that Mars hides a lot of water underground. The last track has been given to us an earthquake

There was a remote time in which Mars, today desert, had rivers and seas. We know some of the remnants that have remained, such as the Jezero river delta that explores the Rover Perseverance But that water may have been more than mere traces. A lot more. New tests. A geological study conducted thanks to the propagation of seismic waves on the red planet has obtained new evidence of the existence of water on Mars. Although the study itself does not imply a definitive test, it joins the list of studies that indicate that the neighboring planet is not as dry as it seems. A wet past. The Martian oceans had a short duration In geological terms. According to estimates, these would have disappeared between 4,100 and 3,000 million years ago (our solar system has about 4.6 billion years), in periods called Noeic and Hesperic. The lower gravitational attraction and the lack of a magnetic field that protect the Martian seas of the solar wind left Mars without superficial oceans. But from that water there was more than a handful of marks in the geography of the red planet: the water in solid state lasts ice -shaped either Integrated into its minerals. The enigma of the missing water. Some researchers detected a problem, and it is the difficulty that the sum of evaporated water, frozen or embedded in minerals could represent the total water that was once on Mars, they explain In an article for The conversation Hrvoje Tkalčić and Weijia Sun, co -authors of the recent geological study on water on Mars. Insight, to the rescue. In his recent study, the team took advantage of the data captured by the seismometer that the probe Insight He kept operating on Mars during his activity. During this period, Mars suffered an earthquake and received the impact of several meteorites, events whose seismic waves were recorded by the instrument aboard the now deceased probe. Studying the spread of these leads, the team identified an “anomaly” in a layer of the Martian subsoil located between 5.4 and 8 kilometers under the surface. It is a “low speed layer” that, according to the hypothesis proposed by the equipment would correspond to a layer of porous rock stuffed with water, “like a saturated sponge” or “something similar to the aquifers of the earth.” A lot of water. This layer could hide a significant amount of water, enough to house the water that dfalta in the accounts of the experts. “We have calculated that the ‘aquífera’ in Mars could house enough water to cover the planet in a global ocean of a depth of between 520 and 780 m, several times more water that keeps the Antarctic ice layer.” The details of the study will be published In an article In the magazine National Science Reviewbut for now we have to settle for a draft. Tests accumulate. This It is not the first time that we get evidence of the existence of vast amounts of water in the Martian subsoil. A little over a year agoa study conducted from the data of the European probe Mars Express reached a similar conclusion, that of the existence of huge amounts of water, enough to create an ocean of several hundred meters deep, in the Martian subsoil.

In the last 20 years, colorectal cancer has doubled among young people and we didn’t know why. Now we have a track

by

In the last 20 years, the incidence of colorectal cancer has doubled in young adults and that has fired all alarms. Above all, because while this type of tumor shoots, we have no idea why. Now, a study headed by Spanish researchers has found a suspect: it is called colibactin and a bacterial toxin produced by some strains of Escherichia coli. The colorectal epidemic. The term is “epidemic”, yes. As Manuel Anse explainedthe alarm jumped in the US in the late 2000s: while colorectal cancer decreased in people over 70, growth rates in children under 50 grew at a rate of 1.5%. In Europe, the data suggests that it has arrived to grow to the rhythm of 8% Between twenty -year -old. It was a huge public health problem. But, above all, it was a mystery. What could be behind all this? The first track. In 2020, a research team from the Netherlands discovered that certain strains of Escherichia coli They produced colibactin and that toxin could produce cancer mutations In the children’s DNA. It was an interesting, promising way; But there were too many conditional in the idea. Those conditionals are those who have tried to eliminate the investigation that It has just been published in Nature. What have they done? They have analyzed the DNA of almost a thousand tumors of this type of 11 different countries (and three continents). Not only that: they have examined varieties, typologies and demographic features. And what they have found is more than interesting. To begin with, there are two genetic brands related to the toxin in question that are 3.3 times more common in tumors of young people (compared to those of people over 70 years old). To continue, “they are especially prevalent in countries with a high incidence of colorectal cancer in young people.” What does this mean? “Mutational firms are a kind of historical record in the genome; they point out that exposure to colibactin in early stages of life promotes colorectal cancer of early appearance,” Ludmil Alexandrov explainedfrom the University of California in San Diego. Everything seems to indicate that the harmful effects of this toxin begin soon (in the first 10 years of life). That is, “if someone acquires one of these driving mutations at 10 years, decades could be advanced in the development of colorectal cancer and suffering from age 40 instead of 60, “explained Alexandrov. It is great news. No, it’s excellent news. Insufficient, preliminary and still precarious: but if we are clear, it is that to contain the epidemic we must understand where it comes from. And, for now, it seems that it comes from the modern world. “In the most industrialized countries there is an increase in cases of infection with this strain of Escherichia coliwhich leads us to think about changes in lifestyle “, Díaz Gay says in the country. How can we use it in our favor? We do not know, but we will discover it.

The Curiosity Rover has found its best track so far that Mars was a habitable planet

by

NASA’s indefatigable Curiosity Rover has found one of the most forceful evidence until the date of the past habitability of Mars. But also of the fragility of this habitable ecosystem. The finding. Curiosity arrived in Mars on August 6, 2012. Covered with dust and with deteriorated wheelscontinues to put the Gale crater in which he landed. In a stretch of 89 meters of rocky strata, on the slopes of Mount Sharp, a discovery has caught the attention of scientists. According to a study Published in Science magazineX -ray crystallography instruments and Curiosity gas analysis have detected large amounts of siderita, an iron carbonate ore, between sulfate rich rocks. Why it is important. Although I know They had detected carbonates on Marsthis discovery is exceptional for several reasons. First, the abundance of Siderita: it reaches between 4.8 and 10.5% of the weight of three perforated samples, which have been baptized as Tapo Caparo, Ubajara and Sequoia. Second, the purity of the siderita. It is almost pure feco3, with very little magnesium or calcium, which contrasts with other Martian carbonates. Third, its coexistence with highly soluble salts in water: calcium sulfates and magnesium sulfates. All this fits with an ancient evaporation process. What tells us about the old Mars. The formation of this siderite implies that the Martian atmosphere contained sufficient carbon dioxide to dissolve in water and react with the rocks. When precipitating as mineral, the CO2 was kidnapped In the rocks. The Gale crater was a lake that gradually dry out over time, leaving behind these layers of different salts or minerals. The study estimates that recent samples could house between 2.6 and 36 millibars of atmospheric CO2, up to six times the current CO2 pressure on Mars, confirming that There was once an important carbon deposit interacting with surface water, a key requirement for habitability. An incomplete cycle. But the story does not end there. The team found evidence that part of the siderite that formed was subsequently destroyed. A close sample (nicknamed Canaima) lacked a siderite, but contained abundant iron oxyhydroxides. Samples with siderita (tapo caparo, ubajara, sequoia) also contained these oxides in variable quantities. Researchers believe that it is due to a diagenesis process. Subsequent fluids interacted with the rocks, partially dissolving the siderite. This destruction oxidized the iron forming oxihydroxides, and released part of the CO2 previously kidnapped again to the atmosphere. This training cycle (CO2 kidnapping) and partial destruction (CO2 release) constitutes the best evidence so far of a Old carbon cycle on Mars. However, Siderita’s persistence indicates that it was a partial and incomplete cycle: more carbon was kidnapped than was subsequently released, unlike the carbon cycle of planet Earth, which has maintained a greater balance over geological time. A fragile habitability. The discovery reinforces the idea of ​​a habitable primitive Mars with liquid water interacting with a CO2 rich atmosphere until The warm and wet days are over. He tells us that the planet was habitable, but also that habitability is something very fragile. Perhaps a lesson about the climatic stability of our own planet in the face of climate change. Mars, once again, serves as a planetary laboratory to understand the evolution and fragility of the habitable worlds.
