Some people believe that sleeping on your side or stomach creates “sleep wrinkles” on your face. It’s exactly the opposite

by

The Internet is full of golden rules for have ‘eternal youth’this being the holy grail that many would like to have in their hands right now. Among these pieces of advice, there are several that can be quite annoying, such as that you should not sleep leaning on the side that is wrinkled. But… how true is this? The benefits of sleeping well. The sleeping position is essential to have a good rest. Because sleeping on your stomach is not the same as sleeping on your left side. In the first case, the cervical spine can suffer a lot and in the second the hated gastric reflux. can be seen reduced. But now it comes into play that sleeping on one side or the other can cause more wrinkles on the face due to the hated gravity that generates a mechanical effect that causes the face to fall and wrinkles to appear. But science disagrees on this one and puts the blame more on biology with cortisol and collagen. The myth of ‘Sleep Wrinkles’. The theory seems logical: if you spend 8 hours squishing your face into a pillow, that mechanical compression should leave a mark. There is often talk of “sleep wrinkles” (sleep wrinkles), which, unlike expression lines, caused by smiling or frowning, would be caused by having your face against the pillow. It is something that some experts defend like those of The Aesthetic Society, which suggest that sleeping on your stomach or side favors the appearance of vertical lines due to this chronic pressure. Other opinions. The clinical evidence It is quite limited in this casesince many of the statements that defend this myth come from the field of cosmetic surgery and with very limited groups of people. There are even articles that suggest that there is no clear relationship between sleeping in a certain way and having more wrinkles. The consensus right now is that sleeping on your back could theoretically reduce the formation of compression lines. But obsessing over this is not the best, since if having this position is uncomfortable and the quality of sleep decreases, then the biological weight it will entail will have a great impact on wrinkles. The real threat. This is where science stops being speculative and becomes blunt. If there is something that ages your skin, it is not the pillow, It’s sleep deprivation. When you get little sleep, the body enters a state of physiological stress, raising levels of the hated cortisol, the stress hormone. And elevated cortisol is the great enemy of our skin’s youth. This is because it can inhibit the cells that make collagen (the scaffolding of the skin), making the skin less elastic and increases metalloproteinases. This word, so long, is nothing more than an enzyme that breaks down that fundamental collagen that we have in our skin and that keeps it firm. If we do not produce it or destroy it, the wrinkles will appear there. With data. A key clinical study presented in ScienceDaily showed strong results: People with chronic poor sleep quality showed clinical signs of accelerated aging with fine wrinkles, uneven pigmentation, and sagging. But the most important thing is that if UV radiation from sunlight was also added to all these factors, the skin’s recovery would get worse. And this is where the need to have sun protection when going outside came in.

Mars has become an obsession. Missions like those led by SpaceX demonstrate this and the truth is that going is the “simple” part. The really difficult thing is terraforming the planet to be able to carry out long-term missions in the field. In the movie ‘The Martian‘We already saw how an astronaut survived on Mars based on field-grown potatoes and, although it may seem like science fiction, we are already making progress on it. But we also need to build, and it is best to use Martian dust to create bricks. As? With the help of two bacteria. Biofoundation. Both the Moon and Mars are covered in dust. This mantle is made up of a series of elements that we can use to our advantage to create construction materials. It is much easier to figure out how to transform these materials into something useful than to carry kilos and kilos of materials from Earth, and in a study published in Frontiers in Microbiology addresses that problem. In it, researchers from the ‘Giulio Natta’ Department of Chemistry, Materials and Chemical Engineering of the Polytechnic of Milan describe the process of transforming Martian regolith into a concrete-like material through a process called biocementation. And the proposal is to use a duo of bacteria capable of carrying out this transformation. ‘Mason’ bacteria. The protagonists are the Sporosarcina pasteurii and the Choococcidiopsis and the key process of the technology is ‘Microbially Induced Calcium Carbonate Precipitation: a process by which microorganisms generate calcium carbonate at room temperature. In the case of the Sporosarcina pasteuriithe process is based on ureolysis. Thus, the bacteria produces the enzyme ureasewhich hydrolyzes urea into ammonia and carbonic acid. When released, it raises the pH of the environment, while carbonic acid dissociates into carbonate ions. When they combine with calcium ions present in the medium, they precipitate as calcium carbonate crystals on the bacterial cell walls and on soil particles. A confusing and technical explanation to say that they generate a waste that acts as a natural cement that joins the regolith particles Martian, transforming naturally loose dust into a compact material with compressive strengths similar to those of some concrete mixtures. BIOMEX. On the other hand, there is the Choococcidiopsis. It is one of the most resistant organisms we know – like the friendly tardigrades -. They are capable of surviving in conditions that simulate the Martian environment and, in fact, a few years ago the mission BIOMEX of the European Space Agency demonstrated that strains of this bacteria exposed without any shield for 18 months to both the vacuum of space and solar radiation were intact. Once they were rehydrated, they resumed their metabolic activities. This is important because we have already “proven” the Choococcidiopsis in space, and its role in this story is not because of its ability to convert regolith into concrete, the other one takes care of that, but because of its extreme resistance. What the researchers propose is an association between the two bacteria. Through photosynthesis, the Choococcidiopsis releases oxygen that creates a favorable microenvironment for the Sporosarcina pasteurii Do your job while, in turn, providing favorable conditions for your companion’s survival in the hostile Martian environment. Defensive arsenal. That is, while one works, the other provides food and defense. And, really, the defensive arsenal of the Choococcidiopsis It is imposing. As if it were the armor of a state-of-the-art tank, it has three lines of defense: The first is formed by extracellular polymeric substances that form a thick layer that filters almost 70% of UVA radiation, almost 70% of UVM radiation and almost 90% of UVC. The second line consists of antioxidants that bind to the outer membrane to act as a photoprotector, neutralizing the reactive oxygen species generated by radiation. And the third defense includes UV filters. As if that were not enough, Choococcidiopsis can self-repair its DNA if it is damaged by radiation. Beyond construction. It is resistant and resilient, but before launching flying bells and bacteria to Mars, the team itself details that you have to go step by step. Although different agencies want to build the first human habitat on Mars in the 2040s, it is no longer just that building on the planet is a problem: the question of how these pioneers will return must be answered with guarantees. There are plenty of projects underway to learn how to build and farm on Mars by imitating the planet’s characteristics. At the moment, they are demonstrating that Martian material can be converted into construction material, but there is still a long way to go, such as replicating Martian conditions on Earth to optimize these construction processes. And discoveries such as the work of these bacteria together can lead not only to novelties in terms of construction, but also to potential uses of the capabilities of some of them to produce oxygen on Mars or even use the by-products they discard as an element for crops in space. Ammonia, for example, which could be used as fertilizer for crops. Images | T.

Chema Alonso has signed for Cloudflare and the RFEF after leaving Telefónica. This creates a strange situation for LaLiga

by

Chema Alonso has converted His departure from Telefónica In March in the most controversial play of the year in Spanish football. In a few weeks he has formalized his total departure from Telefónica, He has signed as a technological advisor of the RFEF Arbitral Technical Committeeand now he has announced his arrival in Cloudflare as Vice President for International Development. Why is it important. It is a very peculiar role change. Alonso now works simultaneously for two organizations that maintain structural conflicts with LaLiga: The RFEF, historical rival for the control of Spanish football, with the battle intensified in recent years. And Cloudflare, a company that LaLiga accuses of “collaborating with criminal organizations” by protecting more than 50% of the websites that are illegally soccer. The context. For more than a decade in Telefónica, Alonso had privileged access to LaLiga antipiratry strategies. Telefónica is more than who issues LaLiga: it is their strategic partner, fundamental in the fight against illegal emissions and who technically executes judicial blockages. Audiovisual rights represent 40-50% of LaLiga’s income, and Movistar Plus+ is its largest buyer. The irony is that the man who helped to design antipiratía defenses now works for those who help to overcome them. The facts. Cloudflare maintains an open war with LaLiga. The company has implemented privacy protection technologies that also hinder illegal content tracking: dynamic IP changes, HTTP port blocking, anonymization systems … and above all, Ech. LaLiga got judicial orders in recent months to block Cloudflare IPS during the parties, which affected thousands of legitimate websites that were left without service. Cloudflare demanded from LaLiga for these blockages, but Justice rejected it And it was In the hands of the Constitutional. In parallel, LaLiga and the RFEF fight a constant battle for calendars, schedules, disciplinary jurisdiction and audiovisual rights. They are not partners that cooperate, rather they are institutional rivals who have starred several struggles for the control of schedules, that of the Super Cup or The institutional battle that starred Thebes and Rubiales. For his part, Telefónica spent months on the war between LaLiga and Cloudflare, but He ended up taking sides. Obviously, for the first. Between the lines. He Timing It does not seem accidental. Three strategic movements in a few months. Alonso is positioned as the only actor with direct influence on two fronts against LaLiga. And armed with privileged information about their strategies. Your appointment in the RFEF will give access to arbitral systems. And from Cloudflare, he knows how LaLiga operates after so many years in his partner: his possible technical weaknesses, internal processes, calendars of legal actions. In perspective. Cloudflare could well be executing a “regulatory capture” operation: place someone with technical credibility in the regulatory body, influence the technological policies of Spanish football from within, neutralize future antipirable regulations. For the company, hiring Alonso is recruiting someone with knowledge Insider As few have. And that makes him an extraordinarily valuable asset. Yes, but. The situation raises unanswered questions. Did Telefónica know Alonso’s plans when he said goodbye? Was your departure completely involuntary? Can LaLiga legally challenge your appointment in the RFEF for conflict of interest? What we do know is that the signing for cloudflare does not imply a conflict with Telefónica for possible agreements for exit, as we have been able to know by knowledgeable sources of the matter. From Xataka We have contacted LaLiga, who has declined to comment on this. The same has exposed Telefónica. We have also tried to contact Chema Alonso, without success: The ‘contact’ section of its website It only offers as contact methods a postal address and the possibility of sending previous messages using the platform Mypublicinboxa company of which it is a shareholder and promoter.

Figure creates a system to make large -scale humanoid robots. And of course, there will be robots manufacturing robots

by

We had something forgotten to robots, but for A few months We don’t stop to return to hear about them. There are important efforts from companies such as Nvidia – who just put All meat on the grill-, Boston Dynamics or Teslabut there is another company that is pushing strong in this sector. It is called Figure, and has just announced a promising project. Botq. This is the name of the mass manufacturing platform of humanoid robots Announced by Figure. The idea is simple: to create a totally oriented infrastructure to that production of high volumes of robots that end up being used in all types of scenarios. 12,000 humanoid robots per year. The first generation of Botq will be able to produce 12,000 humanoid robots a year, but the company highlights that this is only the beginning “and we will climb considerably from there.” Manufacture with vertical integration. The company will control the construction process and its quality to ensure that the robots that end in the market have according to them the highest quality. They have also been working on software solutions for months to attend these high volume manufacturing processes. Robots building robots. The Humanoid Robots of Figure They already caught our attention last summer, and now these robots will participate in the manufacture of other humanoid robots. That, they say, will happen this year, but in addition “the number of humanoid robots involved (in manufacturing) will grow substantially over time to increase the automation of production lines.” By the way: Elon Musk has an identical idea. Figure 03 on the way. Its current humanoid robot was complex both in necessary elements and in manufacturing processes, but with it they have learned how they can reduce the number of components and how to improve production. And more efficient processes. Thus, instead of CNC machines they will use techniques such as injection molding or pressure foundry that allow “thousands of hours of manufacturing.” In fact, in some components that needed a week to be manufactured with CNC machines, times have gone from only 20 seconds.

What happens when its creator creates them biased

by

Elon Musk has always defined itself as An “absolutist” of freedom of expression. Precisely one of the objectives when he bought Twitter was to turn it into a “public square” in which to talk about everything without tap. It seems that he is achieving it, but now he goes further. Now we want us to believe that Grok 3 will always tell us the truth. Politically incorrect. According to him, Grok 3 “is an AI that seeks the truth to the fullest, although sometimes that truth is at odds with the politically correct.” As they point out In TechCrunchhe said it yesterday during the presentation of this new family of AI models. Of censorship, little or nothing. Grok’s previous versions have already demonstrated a tendency to have a tone and “psychology” different from that of their competitors. The first version was especially striking for its sarcastic toneand with Grok 2 things got especially interesting In the field of censorship. Above all, because it did not exist, and for example it is possible Generate Deepfakes of famous characters Without any problem from any X. Grok 3 and the problem of meaning the truth. Musk’s promises in this regard are striking, but hardly realizable. The reason is simple: that the absolute truths exist is already the object of debate in itself, but there is a powerful argument against: the truths are usually relative and depend on the context or point of view. The facts are there, but their interpretation is absolutely variable and is subject to biases. Humans, yes, but afterwards, also from AI. A neutral AI? Grok 3 seems to want to aspire to become a neutral the AI ​​that gets to the facts and that tells us the truth. Here an element in favor of these models is that lately they cite the sources on which they are based to give their answers. For example, perplexity, and that helps we can contrast those answers. OpenAI is (a little) left. 2003 studies They detected that models of AI like chatgpt had certain biases and seemed to position themselves more towards those who support the protection of the environment, towards libertarian ideologies and towards political lefties. Gemini, Google’s model, was criticized for creating “woke” images of viking or black Nazis, for example. Grok 3 could “talk” like Donald Trump. That an AI is politically incorrect makes us wait for unique responses. Dan Hendrycks, director of the Center for Ai Safety and director of Xai has raised How an AI model could respond as Donald Trump does. Direct, without ambiguity and without taking into account the politically correct. That can be irritating, but it would also allow unpopular opinions and controversial points of view. It was biases, for better and worse. Of course, theoretically without violating social norms and ethical principles, such as XAI explains in his “framework for risk management”. Partisan models. He Hendricks study He evaluated with what US politician models such as GPT-4O, Grok, or call 3.3 were more aligned, and according to their tests everyone seemed to be closer to Biden’s vision than Trump’s, Kamala Harris, or Bernie Sanders. It develops the idea of ​​what calls a “citizen assembly” in which EUU census data on political issues would be collected and then use those answers and modify the values ​​of a LLM Open Source. At this time that model would have values ​​that would be closer to those of Trump than to Biden, for example. But. The truth is that Grok had to be updated last August precisely not to say the truth. Five Secretaries of State in the US They warned that this chatbot was spreading misinformation when users asked about information about the then imminent elections. The change did not affect Grok’s ability to Generate Deepfakes Of the candidates, although in September 2023 x eliminated The capacity of some users to republicate electoral misinformation. Training is key. The AI ​​learns from those data that we provide in the training process, so the biases that an AI may have will have their origin in that data. If we train AI with data that profile your answers to a certain ideological current and criticize another, the theoretically replicate that position in your speech. No details have been given about how Grok 3 has trained and it is possible that we never know it, but if Xai wants us “Adjust” your perspectives and biases. In Xataka | X has been filled with very strange photos of celebrities. The culprit is Grok, which has no limits in its creation of images

After setting upside down the AI ​​industry, Depseek launches its first model that understands and creates images: Janus Pro

by

In full hangover for its model R1Deepseek has just launched Janus Pro 7ban AI model to generate images from text and understand other images that are introduced. And yes, it is also open source, although with An asterisk similar to the flame. Why is it important. Until now, multimodal models have had to juggle between understanding and generation of images, sacrificing efficiency or performance. Janus Pro 7B resolves this dilemma with a new proposal: unifies the understanding and generation of images in a single architecture. Innovation. The model introduces a “double track” system for visual processing: Separate the coding paths to understand and generate images. It maintains a single transformer to process all the information. Use Siglip-l as visual encoder for 384×384 pixels. Janus Pro comparative in the face of your predecessor for several applications. Image: Deepseek. This resolution is its main inconvenience, it seems much more oriented to already experience uses of little ambition than to the applications that we can assume other proposals such as Midjourney either Freepikwhich usually start from 1024×1024 pixels. However, Janus Pro is not a generator of images to use, but a multimodal model with several capacities. Of course, this resolution allows an optimal balance between quality and processing speed … for uses that are conducted with it. Between the lines. Janus Pro 7B’s architecture is especially relevant for its efficiency: Compact size of 7,000 million (“7b”) of parameters. Higher performance to larger specific models. Open source under MIT license for the repository, although the model itself requires accepting the Deepseek license. The MIT license It allows anyone to use, modify and distribute the code freely, even for commercial purposes, provided that the original copyright notice is maintained. It is one of the most permissive licenses that exist. The Deepseek licenseon the other hand, it is free and allows commercial uses, but includes specific ethical restrictions, such as the prohibition of military use or the generation of misinformation. In perspective. Janus Pro 7B is not only another multimodal model, but a new paradigm in the architecture of IAS that can see and create. Its unified but decentralized approach may well end up influencing future developments. The model is built on Deepseek-Llm-7b-Basethe base language model of the Chinese startup, announced in August 2024. of it inherits its language processing capabilities while adding advanced visual abilities. Its 16X subsample system for the generation of images allows you to maintain efficiency without compromising quality.
