Drinking a glass of water before eating is one of the most common “tricks” to lose weight. Science has something to say

With the summer just around the corner, many people seek to lose weight quickly. We have seen it with challenges like Skinnytok, Shots of vinegar either Liquefied Céspes. In the midst of so many “miraculous solutions”, there is a advice that stands out for its simplicity: drinking a glass of water before each meal. It sounds very easy, but is it another myth détox or is there something true? A glass of water. At first glance, it looks like a quite simple premise. Drinking water before eating can “favor satiety” and help eat more conscious way, as the media have explained as Telva either Vogue. In theory, when occupying space in the stomach, water would reduce the feeling of hunger. But like He has warned Dr. Robert H. Shmerling, of Harvard’s Faculty of Medicine, in an article for Harvard Health Publishing, “human physiology rarely follows such simple rules.” Science behind. Dr. Shmerling He has evidenced That it was a premise “too pretty to be true.” In his article he has detailed that although drinking water before meals can generate a mild fullness of fullness – to activate the stomach mechanoreceptors – the effect is limited and passenger. In fact, as you have continued arguing, some studies support the idea in older peoplethere is even evidence that suggests that, within a hypocaloric diet, who drink water before meals can lose more weight in 12 weeks than those who do not. However, there is a nuance to take into account and that is that There is no robust evidence of long -term effects or in large populations. And other associated theories –Like cold water burns calories by thermogenesis– They have been denied in recent studies. Where there is consensus. The point is not in so much to drink extra water, but in what is stopped. Changing soft drinks, energy drinks or alcohol for water can have a real effect on weight loss. According to May Clinicthat simple gesture reduces the total consumption of calories without conscious effort. In addition, staying well hydrated improves physical performance, exercise resistance and recovery. Not because water “weights”, but because it helps sustain a more active and healthy lifestyle. The shortcut culture. The popularity of tricks like this also responds to a social need: to find fast, simple and effortless solutions to a complex problem such as weight control. In a society obsessed with thinness – especially among young women – they proliferate The calls Life Hacks that promise immediate results. As He already explained for Xataka The psychologist specialized in TCA, Sara Bolo, the worrying thing is that many of these tips end in apparently “healthy” behaviors, but hide eating disorders. It is simply water. In a context where “fast tricks” abound, it is advisable to remember that, as Dr. Shmerling has summarized: “If you think it works for you, there is no damage. Remember that no glass of water replaces a balanced diet.” Image | Unspash Xataka | Nostalgia for the 2000s has brought something else: the obsession with flat belly and radical thinness

Liquid Glass, iOS 26, Macos Tahoe, Watchos 26, the new Games app and all the news left by Apple’s WWDC 2025

Apple has chosen the WWDC 2025 To launch a clear message: its ecosystem needed deep reorganization. And he has done so starting with the most visible, such as design, and extending to the most structural, including the name of its operating systems.

He is going as good as everything else in China

This is Liquid Glass, the new interface of iOS, Macos, Ipados and Watchos

Great changes were expected to the Interface of Apple’s operating systems, and we already have them with us. Liquid Glass arrivesa new design language that makes use of translucent elements throughout the interface. Alan Dye, head of human interface in Apple, presented this “inspired” vision “redesign. This “expressive material” precisely adopts the appearance of a layer of liquid crystal that applies to drop -down menus, buttons and other visual elements. There is a unique effect also on all these visual elements: They are translucentbut they act as a unique lens that shows what is underneath as if those elements were actually made of that material. Transparencies are very realistic thanks to the effects that mimic this glass effect. In the iPhone wallpaper, for example, the time digits show the background color slightly modified by the effect of “liquid crystal” itself. This new interface adapts without problems in the dark mode if necessary, although Apple showed above all clear mode in all captures and demonstration animations. That interface promises to be especially clean, although a priori does not seem especially radical: we have a desk that seems more polished and with more “air” than its predecessor. There is something especially important: those visual elements are universal throughout the Apple ecosystem. The Liquid Glass design language reaches iOS, macOS, iPados or Watchos equally. All of them take another leap: Theoretically this year Macos 16 or iOS 19 were going to arrive, but instead we will have macos 26 or iOS 26. In development …

Google wants to replicate in its glasses with Android’s success in mobiles. Unlike Glass in 2013, now it makes sense

In 2013, Google Glass He promised to revolutionize our day to day with smart glasses that would give us real -time information. However, the project ran into multiple obstacles that led him to commercial failure. Now, more than a decade later, Google bets again on a similar proposal, but this time The cards on the table are completely different For two reasons: Android XR and Gemini. “If you go back and look at the original video of Google Glass’s launch, I think the vision was great. This idea of ​​a product that you can take and that gives you the right information at the right time was incredible. An interview during the Google I/O In Googleplex offices in Mountain View, California. The equation that was missing in Glass Image | Antonio Zugaldia The Google I/O. has left us with great novelties Around the company’s products and ecosystem. Almost overnight, Google bombard us with A flood of functions and products oriented to its Android ecosystem that Gemini has hugged strongly. Among some of the most prominent aspects we could try THE NEW AI MODE which replaces Google’s traditional searches with Search Live, Flow with the new Image 4 models and I see 3and even the new mixed reality devices with Android XR as Project Moohan and His glasses with Gemini. Payne has given us more context about the plans that the company has for the New ecosystem they are developing with Android XRwhich already borrows all the work behind android for mobiles. The Executive identifies three key elements that were not present at the time of Google Glass and that now exist: artificial intelligence, an ecosystem of robust applications and truly usable hardware. Image | Xataka “One thing that did not exist was the AI. Make Those experiences They were reality required some fundamental advances in artificial intelligence that had simply not occurred yet. Gemini is here now, “Payne explains. The second factor is the application ecosystem. While for Glass the developers had to build specific applications in a special development environment, Android XR takes a radically different approach. “We are building a platform. We work with the ecosystem. We include all Android developers. Now, instead that developers have to create a new application, the app simply works,” says Payne. Image | Xataka This approach means that All Android applications will work on Android XRfrom mobile phones to virtual reality glasses and devices, eliminating the input barrier that existed previously. With this, Google wants to leave behind That fragmentation problem That has been ballasting Android for years, offering universal compatibility, unified development tools and the use of open standards such as Webxr, Openxr and Vulkan to expand their ecosystem. Gemini as an intermediary between the software and us Interface that Google raises for Android XR in Project Moohan | Image: Google “We think Gemini is for XR what the touch screen was for smartphones,” says Payne, establishing a parallelism with The 2007 iPhone which changed the mobile industry forever. According to Payne during the interview, Google’s vision for his smart glasses is to create “a natural conversational interface that understands what is important for you and gives you the right information at the right time.” Glasses, equipped with cameras and microphones, They can feed Gemini with real world informationwhile the connection with the phone gives access to the user’s digital world. Real -time translation test with Gemini at glasses | Image: Google Glasses that people really want to wear The third pillar is hardware. Google has made significant investments in screens technology, such as The acquisition of Raxumwhich manufactures “tiny and efficient energy” monolithic micro LED screens, according to the manager. The company also seems to be considered as important Collaboration with brands Fashionable like Warby Parker and Gentle Monster to create “really elegant glasses, glasses that people really want to wear.” “What we learned is that people really need to feel that they wear normal glasses to wear them all the time,” Payne acknowledges about the lessons learned from Glass. And to see, the proposal that Google offered in 2013 with Glass cool a lot, but to win the mass public, perhaps opting for One more approach mainstream In design be more appropriate. Proof of this is the irrefutable success of the Ray-Ban Meta Not as a product, which also, but as a format. Privacy of what we know in Android PROJECT MOOHAN | Image: Xataka Aware of privacy concerns generated by a continuous recording device, Payne also told us more about the approach that Google is adopting in privacy and security. On the one hand, the idea is that the device offer key switches and markers To know when the user is recording, activating their location or sending their information to their servers. “Privacy ends up being the basis of anything we develop around the ecosystem,” says Payne. In the current prototype we cannot talk that these measures have been applied because they are not for sale to the public yet and everything indicates that the company still has a long journey ahead before marketing its glasses. Of course, Payne has been able to advance that The idea is to apply the Android already familiar permissions framework related to privacy, together with that series of switches and mechanisms incorporated into the hardware to protect the user. It is clear that having constantly connected glasses and that they see everything your eyes see must land with a crucial and determining approach in this aspect. The explosion with AI can be the ideal time to boost this technology As we have seen, for Android XR to stop being a niche and become a mainstream product, Payne identifies The confluence of three factors: abundant and useful applications, diversity of devices for different needs, and a powerful interface fed by AI. “No one is saying: ‘Do you know what I want to do? I want to wear a helmet. I want to wear smart glasses. I don’t know what they do, but … Read more

The AI ​​and technology of today drive the dream that Glass promised

The augmented reality is not new for Google. In fact, it is a segment in which they have wanted to play their foot for more than a decade. Glass It was the project that made us dream of glasses with which we could obtain all the information we would like directly from our retina. The problem is that Technology was simply not ready At that time. With the arrival of the generative AI, the balance has ended up balancing a lot. During The Google I/O.the company showed a prototype of glasses that reminded us of Google Glass, now driven with Gemini. Us We have been able to test this same prototype During our visit to the event and under these lines we tell you what we have found. Notice for navigators: they are still a prototype, so Google’s mission has been to collect feedback through closed -door tests. Glass lacked two keys: an AI like Gemini and the technology we have today Google’s return to the field of smart glasses seems to be more alive than ever, especially after knowing the development of the platform Android XR and his collaboration with Samsung and Qualcomm for the creation of Project Moohanthe augmented reality glasses that have the objective of standing in the Apple’s proposal with Vision Pro. Real -time translation can become one of the functions most demanded by these types of devices | Image: Google The company seems to come back with A renewed approachimportant strategic alliances and a much more mature technology. Android XR wants to spread through glasses of multiple formats And during the event we have been able to get back a bit with their glasses designed to wear them throughout the day. Google and Samsung They have not hidden with design Project Moohan and have not done so with these glasses either. This discreet approach seems inspired by the recent collaboration of Goal with Ray-Banand it is a clear recognition that smart glasses need to be, above all, glasses that people want to wear. The test (with failures) during the Keynote of the Google I/O | Image: Google During the test with this prototype I could check How Google has integrated its artificial intelligence assistant Gemini in a format that takes advantage of the first person vision. Unlike the original Glass proposal, where technology was the protagonist, here the experience flows more naturally. We would have loved to show you the interface during the test or a closest close -up of the glasses themselves, but unfortunately were some of the restrictions we had to meet. Sergey Brin himself, Google co -founder, recognized during the event the mistakes made with Google Glass, admitting that then They did not understand the complexity of supply chains in consumer electronics or how difficult it would be to make smart glasses at a reasonable price. The I see what you see Gemini It develops really well While we interact with the assistant through the glasses. The wizard uses the camera incorporated in the glasses to ‘see what we see’. In one of the demos, I stopped in front of a painting and directly asked who his author was and what he represented. Without having to specify to which table I referred to, the assistant responded precisely by providing data on the work and other related details of interest. Prototype glasses in the test with Gemini | Image: Xataka In another of the tests, I could also taste slightly Its potential capacity to help us with any type of taskasking him about the operation of a coffee machine in front of me. The wizard not only identified the model, but detailed the step -by -step procedure to prepare coffee. Although all the tests were in a safe environment where Google workers had control in case something strange happened, these tests implied me Everyone of possibilities that Google counted thanks to Gemini and a technology that is now ‘. Gemini drives device capabilities | Image: Google This ability to “see” and understand the context makes a substantial difference with respect to attendees who only depend on voice or text commands. It’s like having a partner who observes the world from your perspective and helps you when you need it. A ‘todologist’ that helps you in whatever. And that concept of direct aid has also been extended in other projects that Google has underway and that we could also see on Google I/O, as is the case of Search Live. In the current state in which this prototype was, the glasses had A touch button on one of the pins that allows you to activate or pause Geminiso that the assistant is not constantly listening and observing. In addition, when the camera is active, an LED lights so that people around you know that you are recording. This is the prototype on the demos | Image: Xataka The information was projected from one of the crystals, and everything we heard from Gemini could also see it in text. In the current state, the text is something uncomfortable to read, and that I have no view problems. However, we must remember that It is a very premature prototypeso it is a characteristic that surely changes a lot during the development cycle. And it should be remembered that Android XR is beginning to develop this year for this new concept of glasses, as the company has revealed during its Keynote. A strategy of alliances and price will be everything to determine its success What also makes this project of previous attempts distinguish is The collaboration strategy What Google is deploying. The company announced during the I/O associations with glasses manufacturers As Gentle Monster and Warby Parker, in addition to deepening their technological alliance with Samsung and Qualcomm. Google is investing up to 150 million dollars In his association with Warby Parker. Despite the enthusiasm, you have to be realistic: What I could try was a very early prototype with limited functionalities and in a controlled … Read more

Is glass solid or liquid? A much more difficult question to answer what it seems

There is an urban legend that attributes the irregularities in the glass decorated by the Gothic cathedrals to the fact that Glass is not a solid but an extremely viscous liquid that, over time ends up falling dragged by gravity. Well, according to experts, this story is a myth. And at the same time it really has a lot. Yeah, It is complicated. As we learned at school, matter can occur in three states: solid, liquid and gaseous. Then we would learn that the panorama is a bit more complex, with somewhat more unusual phases such as plasma, or the existence of a “Triple point”, A combination of temperature and pressure under which matter can be in three phases at the same time. In An article in The CovnersationPaddy Royall, a professor at the University of Bristol, explained a few years ago some details of this mystery and why the history of the windows of the cathedrals has some foundation Despite not describing a real cause of cause effect: the irregularities in these windows are due to the technique and not over time. For Royall, the key to the matter is in the transition. To understand where glass fits in all this we can think of water or, more specifically, what happens when the water changes its liquid phase to its solid phase. When the water freezes it does so more or less sudden. Small crystals arise from the liquid water, that is, regions where H2O molecules are structured in an orderly and invariable way. This crystallization occurs quickly, as a kind of infection that extends until the whole solidifies. In any case, the water will become ice in a discreet and not continuous process: it will pass from solid fluid without further proceduresso that their molecules will go from disorder to order. The problem is that not all matter seems to behave with that immediacy. And the glass, or rather, the glass are the best example of it. “The problem with the materials that form glass (which include plastics, alloys and ceramics, in addition to the daily ‘glass’) is that there is no obvious transformation. When cooling we cannot say the moment in which the glass becomes solid, ”he explains in Your article Royall And this is not simply due to a matter of temperature but in the same viscosity. So that a material crystallizes its atoms must “order” and structure. As explained to Livescience John Parker, from the University of Sheffield, “(the glass) cools quickly, but as it is so viscous, Atoms cannot be moved in a simple way to regroup in a more orderly solid structure, and are trapped in disorderly formations. ” “(Glass) is by mechanically solid, but with a messy structure like that of a liquid,” adds Parker. Something similar explains Royall In your article in The conversation. “The reason that (the transformation) is difficult to observe is that to do so we would have to wait an extraordinarily long time (much more than centuries),” he says. However, the teacher gives us some details of how atoms and molecules are structured in this solid that is not such. He explains that, if we look with a microscope, we can see how small groups of a few tens of molecules act differently: some are structured in orderly, as in a solid, while those around them remain unstructured, as in a liquid . A difficult experiment In 1927, the one that is considered “was launched”The slowest experiment in history” It is about Brea drop experimentan essay whose objective was to demonstrate that this substance was a liquid of enormous viscosity. Those responsible for the experiment placed an amount of break in a funnel, all protected in a glass bell. Under the funnel, another container to collect the fallen break. After three years letting the break, those responsible for the experiment opened their mouths and left the gravity to do their job. Ten years later the first drop fell. In the 95 years since the opening of the funnel, they have fallen A total of nine drops of break to the second container. This experiment remains active as curiosity and because it can still teach us things. For example, how environmental conditions alter the viscosity of this type of liquids. After the seventh drop (fallen in 1988), the University of Queensland installed air conditioning in the faculty that houses the experiment. The result: a remarkable slowdown of the speed at which the drops fall, that is, an increase in the viscosity of this fluid. So, glass is a liquid, right? The question remains without a definitive answer. In John Mauro’s words collected by Livescienceglass “is neither a true liquid nor a true solid: it has properties of both but has its own state of matter.” “The technical definition It is that glass is a state of non-echinibrated and non-cristaline matter that appears to be solid in the short temporary scale but that relaxes towards the liquid state, ”added Mauro, expert in material science of the Penn State University. The question of the time scale is important. The stained glass windows of the Gothic cathedrals are centuries behind. The temporal scale in which glass is located is much larger. That is why we know that, although there is something true in the legend of these stained glass windows, it would actually need more time so that we could observe changes in the structure of these materials. Much longer. In Xataka | We have discovered that diamonds can compact even more. The result is a much harder material Image | Antoine Pouligny / Jamieson Gordon
