works

His answer is called Zhuri and it already works

by

USA takes years working on methods to obtain solar energy directly from space. What is known as space solar energy is shown as an improvement on the conventional solar plants that we have here on Earth. The density of solar energy in orbit is six times greater than on Earth and the problem of weather interference is eliminated. However, it is true that there are quite a few technological obstacles that must be resolved. Although Europe, the United Kingdom and Japan have already made some proposals, the United States has a very prominent activity around the implementation of this type of projects. Therefore, it was to be expected that sooner or later China, the North American country’s eternal space rival, would join. After presenting several proposals project, Zhuri has finally been selected, with which Xidian University it has already started to work. From geostationary orbit to your electrical devices. The Zhuri mechanism, which means “chasing the Sun” in Chinese, consists of several steps. First, a 4.8-meter dome-shaped mirror suspended on a 75-meter tower is used, which is responsible for concentrating sunlight on a series of panels, similar to those used on Earth. This sunlight is used to obtain electricity, which cannot be transmitted directly in space, so it is then converted into microwaves, which can travel more efficiently. These then pass to a rectifying antenna, known as a rectenna, whose role is to transform these microwaves back into direct current electricity. That is the electricity that reaches the Earth. Other devices. In addition to the mirrors mentioned, Fresnel lenses of 2 to 7 meters wide have also been tested, as they are capable of focusing light even more efficiently, with less expenditure of materials. They even include cooling liquids that help manage solar heat, avoiding some of the inconveniences that it could cause. The first tests have been a success. In the first tests, scientists from Xidian University have obtained energy in the order of kilowatts, so for now the results are very positive. They are not alone. In the United States there are several projects aimed at obtaining solar energy directly from space. For example, Caltech has been researching in this area since 2013 and has already carried out some experiments in orbit in 2023. Also some private companies, as Goalplan to power their data centers with space solar energy by 2030. And, of course, the United States government could not be absent. The ARACHNE project, of the Air Force, is based precisely on this same goal. On the other hand, in Europe the ESA has the project Solaris and UK Space Solar. Both plan to start operating in 2030. And above all, Japan stands out, which has been researching in this area for decades and was one of the first countries to test wireless power transmission. Not to be confused with Reflect Orbital. The United States has other similar projects, as Reflect Orbitalbut they should not be confused, as they are much more controversial. With them, what reaches the Earth is not electrical energy, as with everything we have mentioned so far, but rather sunlight itself, which is “squeezed” even during the night. The objective of both types of projects is similar, but the means are very different. Beware of challenges. All countries that have tried to obtain space solar energy have encountered the same challenges. For example, they highlight problems in addressing the ease of deployment of folding or self-assembling structures, achieving precise microwave aiming, and ensuring the safety of the beams, both for the environment and for aircraft crossing the area where this electrical energy is being obtained. To address some of these handicaps, China uses modular units that fly in formation rather than a single massive structure, thereby improving endurance and making maintenance easier. Short term goals. Logically, the ultimate goal of this type of project is to bring solar energy to any part of the Earth. However, for now, we want to go step by step and achieve small preliminary challenges, such as wireless charging of satellites in orbit or the supply of lunar bases in orbit or on the lunar surface.

build submarines. The last one weighs five tons and works

by

Zhang Shengwu is 60 years old, he is a farmer and has not studied naval engineering, although throughout his long life he has had other jobs that can be assumed to be a handyman, such as a carpenter, welder or in the shipping industry. Back in 2014, Shengwu saw a person on TV building his own submarine and, just like you and I ventured to make a cod pil-pil after seeing Argiñano do it effortlessly (spoiler: it goes wrong), the farmer made the determination to build it for himself. As China Daily tellsnot even his family’s warnings about the risks or the cost stopped him. Just over a decade later, in early July 2025, Zhang Shengwu showed the world his creation with a successful test dive of his “Big Black Fish”, a homemade submarine weighing five tons capable of submerging eight meters, the latest of his creations. It is neither the first submarine he has made nor is it almost certainly the last. Some play petanque, I make submarines. The idea of ​​building a submarine from scratch caught his attention, so he invested 5,000 yuan (approximately 642 euros at the exchange rate) to buy sheet steel, a motor and a battery. In about six months he had built his first prototype, a submarine six meters long, 1.2 meters high, weighing two tons, how Sixth Tone collects. The bad news is that there was a leak. The good news is that the design of its prototype obtained a patent, a formal recognition by the Chinese state of the technical validity of the project. Obviously it didn’t stop there. He then built a surface ship that also got a patent. As Shengwu himself acknowledges, his head is never idle, so he already had the following project in mind: invested 40,000 yuan (just over 5,000 euros) to create the second generation of his submarine, which would later become the Big Black Fish. First submarine built by Zhang Shengwu. CCTV News His masterpiece: he Big Black Fish. He improved and lengthened the hull to seven meters and 1.8 meters high, so that its cabin now seats two people. For more stability, Zhang poured approximately two tons of concrete into the hull as a counterweight and mounted two ballast tanks at the bow and stern: “The tanks collect water to submerge and empty it to float,” explains for Sixth Tone. He didn’t want any more leaks like his previous project, so he welded every joint and installed circular hatches. This boat is capable of reaching speeds of up to four knots and Zhang is especially proud of its performance. So, details that “a small battery and a motor can propel this huge structure underwater.

what it is, how it works and who can use Xiaomi’s AI agent platform

by

Let’s tell you What is Xiaomi MiMo Claw and how does it work?the artificial intelligence platform created by Xiaomi. This is a service that combines the manufacturer’s own artificial intelligence with the platform OpenClawthe popular AI agent. Xiaomi simplifies all of this to the maximum so that anyone can use it. So that you understand it well, we are going to start by explaining what exactly this tool is and how it works. Then, we will tell you who can use it. What is Xiaomi MiMo Claw MiMo Claw is a platform created by Xiaomi, built on OpenClawan open source AI agent framework. OpenClaw allows artificial intelligence to take control of your devices and do things for you on them, both to manage files and to do things on the network. About OpenClaw Xiaomi uses its most advanced artificial intelligence model, MiMo-V2.5-Pro. It is this version of MiMo that acts as an agent, being able to do the tasks you ask of it. Come on, it’s not limited to answering questions, it can also perform actions for you. Xiaomi has been testing this tool in beta for months, and on June 16, 2026, it confirmed the launch of its official version. Its great asset is yesu integration with Kingsoft Office (WPS Office), the office suite that is the Chinese alternative to Microsoft Office or Google Workspace. With this agreement, whoever uses its programs will have Xiaomi’s AI functions integrated. Xiaomi claims that in its internal tests at ClawEval, a testing ground that measures the performance of AI agents, its model had a task completion rate of 63.8%, with token consumption between 40% and 60% lower than that of similar products. Of course, remember that these are data that Xiaomi itself has given, it is necessary to treat the figures with caution. How MiMo Claw works MiMo Claw works as an AI agent, not a chatbot. This means that it is not limited to writing you answers for what you ask, it can take care of perform complex multi-step tasks without you having to guide them through each one of them. According to the data published by Xiaomi, the system can sustain more than a thousand consecutive calls to tools within the same session. This means that you do not lose track of what you are doing, and the logic is not interrupted in a long task. Come on, it’s harder to stay halfway without knowing what to do when the tasks are especially long. This is possible, among other things, because MiMo-V2.5-Pro ​​handles a context window of up to one million tokens. Tokens measure the amount of text and information that can be remembered and taken into account less work. The model natively supports the protocol MCP or Model Context Protocol. It is a standard that acts as a bridge between the AI ​​model and data sources that feed it to give it the information it needs to function. This means that it allows an AI to call external tools, being able to search the Internet, open files or execute code autonomously without the user having to do anything else. As we have told you, MiMo Claw is integrated into Kingsoft Office, so it focuses on the office field. MiMo Claw is compatible with more than 95% of common document formats, such as Word, Excel, PowerPoint or PDF among many others. This allows you to create complete cycles. For example, you can generate a document with AI, preview it and edit it in real time, all without leaving the Kingsoft Office ecosystem or resorting to other platforms. You can also create documents with a single click from templatesmanage files, and execute several tasks at the same time. This entire system is hosted in the cloud, so you don’t need to install anything nor use it on a powerful computer, although this also means that it does not have as much privacy as local alternatives. Of course, it is available 24 hours a day and can continue working or correcting errors while you sleep or do other things. Who can use MiMo Claw MiMo Claw can be used independently on the website of mimo.mi.comwhere in Use MiMo do you have a link for MiMo Claw. Of course, its deployment will be progressive outside of China. The service is in a phase where subscriptions and technical support for abroad are not yet enabled. Even so, when it arrives its free usage time will be 4 hours. MiMo Claw’s integration with Kingsoft Office is also designed for the Chinese domestic market. Therefore, if you use the version of WPS Office available in European app stores you will not find native integration with MiMo Clawit will only be in the Chinese versions. Therefore, at the moment MiMo Claw can only be used in China, and we will have to wait to see if it ends up reaching Europe. European data protection regulations are strict, so it may take a while to arrive.

What is Gemini Spark, what you can do with it, how it works and who can use it

by

Let’s explain to you What is Gemini Spark and how does it work?the new function of artificial intelligence integrated within the application Gemini. This is a response by the company to OpenClaw and others AI agentsbut aimed at helping us manage our digital life. The idea is not so much to do things for us on the computer as to be able to carry out online tasks autonomously, and even when our mobile phone or computer is turned off. We are going to explain this concept to you so that you understand it well, and then we will tell you how it works. What is Gemini Spark Gemini Spark is an artificial intelligence agent created by Google, and integrated into the Gemini application. AI agents are artificial intelligence systems capable of carry out actions autonomously. You ask them to do a task, and they carry out all the steps interacting with third-party services without the need for your supervision. Come on, it’s like a secretary who does tasks for you. In the case of Spark, it will be able to reason based on what you ask of it and the information it obtains from your connected applications. With this, then will take actions on your behalf interacting with these services. With Gemini Spark you can assign it a task and it will start working on it autonomously, even with your phone and computer turned off. And as one of the aspects that always worries security agents, Google assures that Spark is designed to consult you before taking important actions. Come on, you will have the final decision in these things. Spark can be working in the background 24 hours a day, seven days a week when you ask it to do something. It runs on the Gemini 3.5 model, uses the Antigravity harness, and integrates with Google Workspace tools such as Gmail, Slides, Docs, and all the tools in the company’s office suite. The difference with the normal Gemini is the following. AI chatbots require you to have it open for it to do things. Then, you ask them to do something, they respond and do it, and that’s it. The session ends there. Spark for his part maintain a persistent presence in your apps and digital environment, when you give it the order it can work in several steps and continue doing it in the background while you do other things, or while you sleep. How it works and what you can do with Gemini Spark Gemini Spark doesn’t live inside your device, but on dedicated Google virtual machines. This is what makes keep running in the background even if you close your laptop or lock your mobile. It connects to Gmail, Docs, Slides, and other Workspace tools with structured API integrations, making it more predictable than agents navigating the desktop pixel by pixel. This agent can connect natively with Gmail, Calendar, Drive, Docs, Sheets, Slides, YouTube and Google Maps. It is important that you know that these connections are disabled by defaultand you will be the one who decides which of them you want to activate to work with Spark. Spark can use a remote browser to leave the Google ecosystem. This way, they can enter a website and interact with it to perform tasks such as adding products to a shopping cart on your behalf. This tool will be able to do complex jobs for you. You can set recurring tasks to be done as often as you decide, teach it new skills, and let it execute multi-step jobs on your behalf. You can also organize your Google Drive files, even adding them to a spreadsheet by adding tags and notes. It can also automatically extract data from emails, create folders in your Drive cloud, etc. You can also teach it personalized behaviors or “Skills” to repeat, such as reading your last 50 emails sent, generating a style guide with your writing style and applying it when you ask it to write an email, and more. Another thing you can do is configure schedules to organize tasks with schedules or when conditions are met. For example, you can ask that every Monday at nine in the morning scan your inbox and summarize your emails, propose a list of priority tasks, or block gaps in your work calendar. You will also be able to create written documents or presentations from a prompt in tools such as Docs or Slides. It can review events, respond to invitations or schedule calendar meetings, convert email chains into a travel plan, record expenses in a spreadsheet, analyze past bills to anticipate future household payments, add recurring reminders, browse websites and compare options, help you complete reservations, and much more. The most important thing is that all this is going to do under your supervision. It’s as if Spark were an employee, who will send you updates on steps it deems critical, and will require your explicit approval to perform high-risk actions, such as sending emails. Who can use Gemini Spark Gemini Spark is part of the Google AI Ultra subscription. This means that if you want to use it you will have to go for the most expensive subscriptionwhich in Spain means paying a minimum of 100 euros per month. Additionally, Spark can only be used in the United States at the moment, because It is a tool that is still in beta phase. There is still no confirmation on when it will reach other languages ​​and countries, although when it finally arrives it will be able to be used on Gemini websites and apps of Android and iOS. They also plan to integrate it directly into Chrome in the future. In Xataka Basics | 64 free courses for AI with Claude, ChatGPT, Gemini and Copilot created by your own companies

They have asked 1,600 experts how the Universe works. They don’t agree on almost anything

by

We continually read news about new findings that they defy the known physics of the Universe. This may lead us to ask ourselves something: do we know so little about the Universe that absolutely everything challenges it? To answer this question it is important to give a little context. Yes, a lot is known about astrophysics, but when we talk about something as immense as the Universe, even that “a lot” can fall short. Furthermore, much of this information is based on hypotheses that have been accepted as consensus, but not on absolute truths. Therefore, it is not strange that in the largest survey ever conducted It has been proven to astrophysicists and astrophysics fans that there is a lot of disagreement on almost everything related to the cosmos. The largest survey. In 2024, during an astrophysics conference in Copenhagen, a survey was carried out in which 85 experts participated. All of them had to answer a series of questions about some of the best-known theories in astrophysics. With this survey it was seen that there is a lot of disagreement, even in those theories in which there is supposed to be a great consensus. In order to check whether these disagreements were a result of the sample size, a new survey was carried out in 2025, this time with 1,600 people who had to answer 11 questions. Some participants were experts from the American Astrophysical Society. Others were amateur readers of Physics Magazine. With a larger sample, the results were very similar. There is very little consensus. From hypotheses to certainties. Science in general, and astrophysics in particular, is built on hypotheses that evolve as scientific advances are made. For this reason, it is often more full of probabilities than certainties. It is important to differentiate different branches of science. In health sciences, there are certainties. For example, we know that antibiotics attack bacteria and are not useful against viruses, no matter how many people insist on taking them for the flu. We also know that their abuse can be very harmful, since it contributes to the development of resistance in bacteria. Those are certainties, although logically there is also information that evolves over time. In astrophysics, hypotheses accepted by consensus often outnumber certainties. There are very clear certainties, such as that the Earth is not flat or that it revolves around the Sun. But also some hypotheses with which not even experts agree. Cosmic inflation wins. The issue on which there was the greatest consensus in the 2025 survey, the results of which were recently published, was cosmic inflation. That is, the hypothesis that points to an exponential expansion of the Universe which began in its first moments, after the Big Bang. 51% of respondents agreed that this theory explains many problems in cosmology at once and therefore has a high probability of being true. Talking about the Big Bang. The existence of the Big Bang was another of the theories with the greatest consensus in the survey, although the truth is that the figure is nothing to write home about either. 25% of the participants agreed that this event gave rise to the Universe 13.8 billion years ago. On the other hand, there were 68% of people who indicated that the Universe was born at a time when there was a large increase in temperature and density, but they did not indicate when that occurred. Disagreements with dark matter. Gravitational behaviors that do not respond to the observed mass have been observed in the Universe. That is, it seems as if there are massive objects exerting a gravitational attraction on others, but these objects are not detected, not even large accumulations of atoms. There is nothing. 27% of those surveyed consider that this can be explained by the existence of dark matter. However, there are 12% who believe that all this may be due to changes in the behavior of gravity on cosmic scales. That is to say, when we talk about the immensity of the Universe, the gravity exerted by objects is not the same. On the other hand, there are 5% of people who consider that the key is in primordial black holes. Although here we must emphasize that one of the hypotheses about the origin of dark matter is that it is formed in part by primordial black holes, so they would not be denying its existence. String theory to solve incompatibilities. The theory of general relativity was proposed on large, cosmic scales. On the other hand, quantum mechanics talks about the behavior of matter on a subatomic scale. Both questions seem incompatible, but to understand the Universe we need to work at both scales. Therefore, for a long time there has been thought about a theory that helps unify both issues. This, for 19% of those surveyed, is string theory. In it, subatomic particles, instead of being treated as points, are considered vibrational states of a more basic extended object, called a string. Normally, when we try to calculate the energy of a particle by considering it a mathematical point, without extension, we get closer to it eternally. We can do a kind of infinite zoom. On the other hand, when the points are replaced by strings with a minimum length, a result must necessarily be obtained. It does not tend to infinity. On the other hand, in string theory gravity, which not normally considered on a quantum scalearises naturally. Another hypothesis. The point is that, in the survey we are talking about, there are 12% of people who consider that string theory does not solve the problem, but that another theory does: that of loop quantum gravity. This, basically, acts in a completely opposite way. String theory emerges with quantum mechanics as a starting point and tries to find ways to make gravity make sense. On the other hand, the theory of loop quantum gravity starts from the General Theory of Relativity and attempts to quantize it in a way that … Read more

An Atlassian engineer was fired. He then published a video on YouTube explaining how the company works

by

“I was recently affected by layoffs made by Atlassian and wanted to take some time to reflect on the time I spent working there.” This is how it begins the video that Vasilios Syrakis shared on his YouTube channel. The video, titled “I have been fired by Atlassian” seems to be a criticism of the company. It’s something much better. What has happened? On March 11, Atlassian, the company behind software like Jira or Trello, announced that it was going to reduce its workforce by 10%which translates into about 1,600 street workers. The reason, of course, was AI. In the company’s words: “Our approach is not that AI will replace people, but it would be dishonest to pretend that AI does not change the mix of skills we need or the number of roles required in certain areas.” One of those roles was that of Vasilios. The answer. Instead of recording himself criticizing the company’s decision, this engineer opted for something different. What he did was publish a detailed, 38-minute description of everything he built during the eight years he worked at the company. Your video is a masterclass on How the architecture of a company of the stature of Atlassian works and it serves two objectives: it turns your experience into a common good and at the same time it is a letter of introduction for future jobs. what he did. Vasilios did not have a minor role at Atlassian, but for eight years, he worked on the invisible “plumbing” that connects millions of users to Jira and Confluence. In the video he details how Open Service Broker works, the internal platform he built so that Atlassian teams could publish their services on the internet with one click; also the Sovereign system, which acts as the “brain” of the more than a thousand proxies; and how it rebuilt security so that all internal services inherited the same authentication and attack security without having to write it one by one. The context. In the announcement, Atlassian admits that it is achieving very good results. In February 2026 they published their resultsin which they boasted a 23% increase in their total revenues, which reached 1,586 million, and a 26% growth in cloud revenues. Despite the fact that the company is doing very well, 10% of its staff ended up on the streets, including engineers with roles as important as Vasilios’. As mentioned in the Experienced Devs subredditVasilios is careful and in the video he does not seem to mention confidential information about the company, but instead limits himself to talking about the design of its systems, so it does not seem like they could sue him. At the time of writing, Atlassian has not commented on the video, which already has almost a million views.

the idea is reminiscent of how macOS works

The speed of an operating system is not always noticeable when we export a video or open a demanding game. Many times we perceive it in much smaller gestures: a menu that appears instantly or a window that responds without delay. It’s a hard feeling to sell on a spec sheet, but easy to notice when it fails. Microsoft has been trying to convey for months that it wants to improve Windows 11and one of its next adjustments goes right into that area where fluidity is gained or lost in tenths of a second. Low latency profile. Microsoft is testing what is known as low latency profile. The idea is to ask the processor for an additional boost of speed at specific times, such as when opening the Start menu, an application, or certain context menus. We are not facing a function announced as a great novelty for all users, but rather a setting present in test builds. Secure Windows Central who has already tested this profile and has observed an appreciable improvement in speed and response compared to the current public version of Windows 11 25H2. It’s not magic, it’s latency. The reference to macOS does not point to a specific Apple feature, but to a principle that, according to Scott Hanselman, vice president of Microsoft and GitHub, modern operating systems share. “All modern operating systems do this, including macOS and Linux,” wrote in X. Their argument is that this is not “cheating,” but rather a common way to make applications appear faster: temporarily raising the CPU speed and prioritizing interactive tasks to reduce latency. In other words, Windows 11 would be trying to react better in those seconds in which we most notice if the system is accompanying or lagging behind. Spot power. At first glance it may seem contradictory that asking more from the processor also helps to take care of consumption. But reality goes the other way: many modern chips are designed to exert intense effort for a very short period and then return to a low-power state. Applied to Windows 11, the goal would not be to keep the CPU accelerated, but rather to take advantage of a specific push when the system needs to respond to the user. The key is that this impulse does not last longer than necessary. The test has not convinced everyone. Some users criticized on social networks that Microsoft resorted to this type of CPU boost, understanding that it could increase consumption and reduce autonomy, or that the company was leaning too much on the hardware instead of better optimizing the software. Now, Microsoft does not present this adjustment as the only answer to the fluidity problems of Windows 11, but as one more piece within a broader work. Windows 11 also needs convincing. The interesting thing is that Microsoft isn’t just talking about making an animation go a little faster. The company has begun to publicly organize its progress around a very specific idea, its “commitment to Windows quality”, with posts tracking the status of several changes in testing, including a less loaded Widgets view, lower RAM usage, adjustments to the Windows Insider program, and more leeway to decide when updates are installed. The timing is not coincidental either.. All of this comes as Microsoft tries to push users and businesses towards Windows 11, with Windows 10 still installed on just over a quarter of the world’s Windows PCs, according to StatCounter. When I finish that free year of extended security updatesanyone who wants to remain protected will have to update the system, change equipment if their hardware does not meet the requirements of Windows 11, or pay for more support. For companies there is a little more margin, but not infinite: they will be able to purchase one or two additional years of updates, with a cost that will increase each year.
