If you haven’t trained it before, your brain will ignore any attempt to relax.

A very typical (and frustrating) situation can certainly be in the middle of a heated discussionwith pulses racing and jaw very tight. And right at this moment someone blurts out the most irritating advice in the world: “come on, take a deep breath and calm down“. you trybut not only does it not work, but it seems to make you angrier. A reality. It’s not that you are a lost case of emotional management. It is that, according to experts and recent scientific studiesbreathing like technique Immediate help in a “rush” of anger is often a lost battle if prior work has not been done. The ‘high’ problem. Sonia Díaz Rois, coach specialized in anger management, is blunt about it: Trying to breathe to calm yourself in the midst of an emotional peak does not work because the body, in a state of maximum alert, does not recognize slow breathing as a safety signal. And it makes a lot of sense, because when anger flares, we go into ‘fight or flight’ mode. The sympathetic nervous system take command, cortisol triggers and the brain prioritizes survival over reflection. Literally all the machinery is active to deal with the ‘threat’ that has been detected. A sudden change. If at this moment of extreme peak of the organism we want to stop it suddenly with slow breathing without having previously trained, the brain can interpret this abrupt change even as an additional threat or an obstruction. In this way, the only thing that is generated is a feeling of lack of air that will increase the stress you are experiencing. That is why the solution to anger is not to turn it off, but to listen to it. But for breathing to be a useful tool, you must first train it in the calmest moments. This is what is known as creating an ‘anchor’. There are different breaths. Science has an opinion in favor of the need to train this relaxation method when you are not angry. But it has also begun to distinguish which techniques are most effective in these high-stress situations. To this end, a 2023 randomized controlled study compared various techniques of breathwork with the mindfulness medication traditional. The result was finding a very effective technique to improve mood above meditation. It is known as Cyclic Sighing (cyclical sigh in Spanish). The way to do it is very simple, since you only have to do a deep inhalation followed by a short inhalation and a very long exhalation. In this way, those who practiced it for just 5 minutes a day showed greater long-term emotional resilience. Because. Neuroscience explains that by prolonging exhalation (as in the 4-7-8 technique, where you exhale twice as long as you inhale), we directly activate the vagus nerve and the parasympathetic nervous system, which is responsible for “slowing down” the body. Scream or breathe. For years, popular culture defended the theory of catharsis with very typical phrases such as “let it all out”, “hit a cushion” or “scream loudly and say everything you think.” However, it does not seem the most appropriate as indicated. a study published in 2024 about activities to manage anger that has totally denied it. And his reasoning is quite logical. A high-arousal activity such as boxing or literally shouting tends to increase arousal more than it should, and is something that maintains or increases the aggressiveness that you are trying to control. In contrast, low-arousal activities like deep breathing or yoga are the only ones that significantly reduce anger. Even in contexts of acute stress, as seen in studies with COVID-19 patients in 2024guided deep breathing exercises dramatically reduced anxiety and stress, although interestingly they did not have the same effect on depression. Train when you are well. The conclusion of researchers and experts like Díaz Rois is quite clear: breathing is not a panic button that can be pressed for the first time in a fire, but rather it is something that must be trained to be in full shape when necessary. To do this, you must enter when you are well, practicing the sigh technique that we mentioned before or counting your breaths. In this way, the nervous system is being trained to relate the respiratory pattern we are doing with the message that we are safe. Other important points. In addition to all this, science is quite clear that slow breathing practiced just before a negative emotional stimulus reduces its impact. This is something that we can keep in mind when, for example, we are going to enter an exam or a place where we think we are going to be very uncomfortable, where taking a few breaths beforehand can save us a bad drink. What you have to say. With all this that we have discussed, the next time someone tells you to “breathe” while you are angry, remember that they are scientifically right, but that for this trick to work you have to go through a series of training.

20 years after Dolly we still haven’t cloned humans, but stopping aging is feasible: Crossover 1×32

In the summer of 1996, a Scottish laboratory made a breakthrough that would forever alter our understanding of genetics and ignite intense debates about the ethics and the possibilities of cloning. That day Dolly was bornthe first mammal cloned from an adult somatic cell. This milestone, achieved by researchers at the Roslin Institute, opened a new era in genetic engineering and shattered the belief that only embryonic cells possess the potential for the complete development of a new individual. Since then there has been debate about the possibility of cloning human beings, but we have not done it and it does not seem that we will ever do it. Serezade, molecular biologist, researcher and scientific communicator, talks to us about that and many other things this week. But we also discussed with her another fascinating topic: how the latest advances seem to be achieving something long sought after: slow aging. There is a lot of fabric to cut here, and for example the environment, culture and habits shape our DNA. But there are also risks, ethics and genetic privacy intertwined. And all this raises a key question: does it make sense to be immortal?

There are exactly five things that you 100% haven’t dreamed of. And science already knows why

He dream world It has its own rules. It is a place where the impossible seems to be the routine, but, paradoxically, some of the most mundane tasks in our lives become impossible to appear in our dreams. And this is something that can cause us many questions about why we have not dreamed of some specific things. The examples. We warn you that this is something that can break your head, because the question is obligatory: have you ever tried to read a text in a dream? (if you remember) o Have you taken out your phone to discover an incomprehensible interface? All this is not a coincidence, because in reality there are some things that we can never dream like we all expected (even if they are very real dreams). It has an explanation. science has several reasons in his lap to convince us why elements of modern life such as the smartphone or computer interfaces have little place in our dreams. Everything focuses on the fact that during the REM sleep phase the activity in the prefrontal networks of the brain are greatly reduced. And it is precisely here where executive control and language are ‘stored’. In this way, if during sleep these neurons are ‘asleep’, then we will not be able to read a text correctly or even hold a smartphone in our hands. When we sleep, it seems that we don’t want to work or be using our cell phone. This is because in this time range the activity of the limbic area, related to the emotional and visual part, is triggered. This results in the content of dreams leaning towards the associative, visual and emotional, rather than tasks that require a great analytical focus such as operating a complex interface. In this way, the material of our waking life is not literally copied from dreams, but rather is integrated in a selective and transformed way, prioritizing emotional charge over functional fidelity. The nightmare of reading. The same neurocognitive principle that we have seen is the one that explains another of the best-known phenomena: the inability to read texts stably. What is basically caused is that the characters literally ‘move’ or distort because the language networks are not being stimulated as much. This applies equally to numbers, mathematical calculations, or the simple task of looking at the time on a digital clock. Stimuli that require fine symbolic precision tend to become illegible or change constantly. Although some studies with lucid dreamers have shown that basic operations can be performed under experimental conditions, outside the laboratory, the stability of the symbols is almost non-existent. No smell or taste. While sight and hearing dominate the dreamscape, other sensory modalities are virtually absent. Systematic studies based on sleep diaries are consistent in showing that olfactory and gustatory experiences are extremely rare. Figures put its occurrence at approximately 1% of all dream reports. Even in laboratory experiments where the olfactory environment is manipulated during the night, most participants do not report smelling anything in their dreams, reinforcing the idea that chemical senses are a rarity in this state. The mirror. It is another quite common phenomenon in dreams: seeing yourself reflected in the mirror is something almost impossible to achieve. In dreams, this is generated predominantly “top-down”, that is, from the brain networks themselves and with very little or no sensory information from the outside. Because of this, high-resolution details, such as a reflected face, text, or an interface, tend to morph or distort as soon as we try to examine them closely. Visual stability is not the norm. The ancestral content. In stark contrast to the absence of cell phones or books, there is one type of content that seems to be overrepresented: threats. Dreaming about being chased, falling, facing dangers or even elements such as storms or snakes is extremely common. And on many occasions we remember it perfectly because we have precisely woken up at the moment sweating or with our heart pounding. This supports the known “Threat Simulation Hypothesis” (TST), proposed by philosopher Antti Revonsuo. This theory suggests that dreams could have an evolutionary function: serving as virtual “training” to rehearse how to respond to danger in real life. However, the scientific literature itself indicates that this hypothesis, although plausible and supported, is also the subject of debate and presents mixed results when compared between different cultures and environments. Images | Shane In Xataka | Years ago we discovered that our ancestors’ dreams were not like ours. There are now thousands of people trying to introduce biphasic sleep into their lives.

All the autumn we haven’t had until now will hit us squarely. And it is summed up in one word: ‘bombogenesis’

When the day ends, the first big storm of the season will have made its debut in Spain. As I write, the extreme waves and strong gusts are already noticeable in the Cantabrian Sea. But that’s just the beginning: just after Benjamina river of humidity will reactivate precipitation on Saturday and will shift the activity towards the Mediterranean on Sunday. And all this, while the continent’s meteorological agencies have their eyes on the Bay of Biscay where a bombogenesis threatens to turn half of Europe upside down. But let’s go step by step. The countdown. A small chronology of what is going to fall upon us: Thursday, October 23. Today we will experience the peak of the maritime storm and the gusts of wind will be very strong in the Cantabrian Sea. AEMET has activated the red warning. In the late afternoon, rains will be more frequent in Galicia and the northern facade. Friday, October 24. The storm will move towards Scandinavia, but its exit coincides with the arrival of a jet of humidity that will connect the Peninsula with the Gulf of Mexico. Saturday, October 25. This is precisely what will reactivate the fronts near Spain and, ultimately, will initiate a whole series of locally strong and persistent rainfall in the center, west and north of the country. Sunday, October 26. These fronts will cross towards the Mediterranean and, on their way, will cause a drop in temperature, numerous showers and the first snowfalls. And then… bombogenesis. Is another way to call ‘explosive cyclogenesis’; that is, “a meteorological phenomenon that describes the rapid and intense formation of a cyclone or storm in a very short period of time.” In technical terms, we are talking about an explosive intensification of an extratropical storm (pressure drop below 24 hPa in 24 hours at mid-latitudes). Is that what we are going to see? Right now, the likely scenario is that bombogenesis is located to the north (between the Bay of Biscay, the English Channel and the North Sea) with the deepest core far from the national territory. Here their fronts and the sea in the background will reach us. On paper, the phenomenon is most likely to spread into Europe, but it is autumn. Spring and autumn are always difficult seasons to model and that means that we can be surprised at any time. What happens is that then the party begins. Needless to say, looking at what the models say beyond these days is meteorology-fiction. However, there is a possibility that this opens a small door through which different Atlantic storms can sneak in.

I’ve been sleeping badly for years, so I’ve tried “sleep headphones.” They haven’t been what I expected

I’ve been sleeping for years regulate. The classic culprits are discarded: I don’t take late or copiously, I don’t drink alcohol, I don’t take caffeine, I do sports, No mobile abuse just before going to bed… Simply I find it hard to fall asleep and sometimes wake up at several times during the night. So I wanted to whose car more and more manufacturers are climbed. In my case I have tried the Anker Soundcore Sleep A20. Let’s see how. What they are and what they promise Sleep A20 are wireless headphones designed exclusively for sleep. The first thing for what they attract attention: they are dwarves. The second: They are very light. The third: its profile is very low, they do not stand out from the ear. The closed box. Image: Xataka. Image: Xataka. Image: Xataka. They also come with several silicone and “wings” tips to adjust it, something especially important in some vermin that we are going to take sleeping for hours. The important thing is that they are not just headphones: Its application includes several environmental sounds, sleep monitoring and specific functions for the night. They can work in two modes: Bluetooth mode to reproduce any sound from our mobile. Sleep mode with soured sounds in the headphones. The experiment The first night was adaptation. I had never slept with a headset in my life. In addition, I usually sleep sideways. It seemed unlikely that a headset did not bother me. Minipunto for these, because I immediately forgot that I was wearing them. The flat design and the soft, gummy, flexible material, made it barely noticed additional pressure. Zero problem. They stand out practically anything. Image: Xataka. Image: Xataka. Then there was the issue of listening. Put to try, I let the application surprise me with its own proposals, which they call “brain waves with the” created specifically to help us fall asleep. We can choose whether listening to them only for a while, only until we stay asleep or all night. I tried the three: Only for a while: It gives what it promises. If we mark 45 minutes, at 45 minutes it will stop ringing. Only until we stay asleep: The same, detecting the moment we fall. All night: What a bad time. The sound made me wake up a couple of times, something disoriented by him. Perhaps it is a personal issue and there are people who have a reparative dream with the headphones sounding throughout the night. It is not my case and I advise to set the timer in a generous way to ensure that the shutdown will occur. The Yay and the Nay There are four elements that work really well here: Exceptional comfort. They have never been a nuisance. They are soft and with the low profile they are not noticed or sleeping sideways, as a soil alternate. Spectacular battery. 14 hours in sleep mode is something that I can never check for myself. After seven hours of night use, when they woke up they still had about the remaining 50%. Passive noise block. Without active cancellation, but with the right tips they isolate surprisingly well. Reasonable, at least. Useful sleep monitoring. The application records sleep phases, number of turns in bed and preferred position. There is enough correlation with what it says My garmin on duration and phases. And then there are four other elements where they fail. Mediocre audio. That nobody expects audiophile quality. Nor is it the vocation of these headphones. The sound is functional, music lacks depth and warmth. Very limited pre -recorded sounds. There is some variety, but many sound compressed and artificial. The most effective are the noise of color (white, brown, pink). Application Faluta. He tells me that I slept 16 hours when the reality is that at seven hours I took them off and left them on the bedside table. I should understand that absolute immobility for nine hours cannot be equivalent to very deep sleep. In addition, it is not very intuitive when applying one way or another. Problematic tactile controls. In the dark it is easy to activate some function. About the application Falutathere is an example. I have not sleeping 11 hours possibly from the day before my birth. That lack of logic in detection is a negative point. Yes, you can see how much I move during the night: my wife says that 16 turns seems like a fairly reasonable figure. The data collected by the application. Image: Mockuuups Studio, Xataka. Also Atina that I am only able to sleep aside, and I have quantified what I already imagined: I usually sleep more towards the side of the edge. The final verdict The big question with these headphones is whether they really help sleep better. The answer, in my experience, is not. I did not notice differences between the nights with them sounding before sleeping and the nights without them. I thought That the scientific approach of pre -registered sounds would better induce sleep, but it has not been so. My Garmin data, with me every night, indicate very similar patterns with them and without them. And something worse when I tried to wear them playing all night, as I said before. At 150 euros are not cheap, but Yes I see them a clear target audience: the people who need to fall asleep listening to something. For that, I don’t think there are much better options for the low profile and night comfort. And without disturbing the bed couple, if there is. There I see an obvious sense. But for those who do not sleep wonderfully and look for allies of any kind to fall asleep, and not to simply hurry a podcast of True Crime Until we fall round, at least in my experience, these headphones do not miracles. Anker Soundcore Sleep A20, Sleeping headphones with noise block, small design for people who sleep from side, 80 hours of autonomy, Bluetooth 5.3, sleep monitor, personal … Read more

This camera is a dream of fulfilled. And I haven’t squeezed even 10%

This phone is going to be simply incredible. I do not usually start my first impressions with such energy, but the Xiaomi 15 ultra is worthy of applause. In a high -end market in which it could practically copy and paste the table of specifications of some models and others, It is more difficult than ever differentiating, and Xiaomi has achieved it. From a spectacular and differential design to a much deeper mobile photography approach than usual. I have been able to try the Xiaomi 15 Ultra for a few days, and I want to tell you my first impressions with him. This is how Xiaomi money earns – they attract you and catch you Xiaomi 15 Ultra Technical Card Xiaomi 15 Ultra Dimensions and weight 161.3 x 75.3 x 9.4 mm 226g Screen 6.73 “AMOLED WQHD+ 3,200 x 1,440 px (20: 9) 120 Hz Up to 3,200 nits Processor Snapdragon 8 Elite Memory 16 GB LPDDR5X Storage 512 GB UFS 4.0 battery 5,420 mAh 90W fast charge 50W wireless load Rear cameras Main: 50MP, 1 inch, f/1.63 – f/4.0, Hyperois Telefoto: 50MP, F/1.8, 75 mm, OIS Super Telefoto: 200 MP, F/2.6, 100 mm, 4.3x, ois Great angle: 50 MP, F/1.8, 122º, 12 mm Front camera 32 MP, F/2.0 Operating system Hyperos based on Android 15 Sound DUAL SHEEPS DOLBY ATMOS Connectivity Wifi 7Bluetooth 5.4GPSNFCInfrared OTHERS IP68 price From 1,499 euros (16+512 GB) Xiaomi 15 Ultra – 16+ 512GB smartphone, Leica Summilux optical lens, Snapdragon 8 Elite, WQHD+ 6.73 “120 Hz, 120 Hz, 90W Hypercharge, charger not included, black (ES version) * Some price may have changed from the last review Design, let’s talk about design Our Xiaomi 15 Ultra has a very striking, very striking design (if you don’t like inventions, you can always buy it in black or white, but this is a pass). Maybe it is difficult to convey how it feels in photographs, but For photography lovers this is a very sweet toy. It has a finish that mixes vegan leather with glass alloy, does not pick up just traces, has a very good grip and, despite being a huge telephone of 16 centimeters high, is quite comfortable in hand. They wanted to make a tribute to the Leica cameras and, in my opinion, the play has gone well. If we turn it, we find the typical Quad-Curve screen that is so fashionable on high-end phones coming from China. Personally, I do not fascinate the curved screens, but I must admit that this format is quite aesthetic at the visual level and that, at least in my experience, It does not bother at all to the touch or suffer from ghost touches. The maximum brightness is 3,200 Nits (in a 25% portion of the panel in HDR content), and is seen in the sun. The only thing that I miss, taking into account that they have already implemented this technology on one of its tablets, is a matt coating to avoid reflexes. There Xiaomi could have differentiated from the rest of his rivals and compete from you to you with We already know who. Hyperos takes a step towards AI The manufacturers are centralizing efforts in the functions of their phones, and last year we saw a somewhat lagging xiaomi in this aspect. In this Xiaomi 15 ultra we find a section dedicated to artificial intelligence, as well as native integration with Gemini. Everything is part of Hyperos 2 based on Android 15, a somewhat more advanced system. I have to say that I liked integration: it is discreet, The system does not give grilled with messages “I have a lot, you use me”and the few functions that are integrated work native discreetly. Specifically, these are the news in this model: Writing with AI Gallery editor with AI (edition of photographs with generative image expansion, improvement of clarity, draft, videos created with AI) Voice recognition with AI (automatic transcription with distinction between speakers) Interpret conversations with the no connection Interpreter with Ia Subtitles with AI Yes, they are not the most striking or powerful functions of the moment, but it is a simple and honest integration. About the rest, I will detail in the review, although the summary is that Miui Hyperos remains Miui Hyperos This mobile is made by and for photographers Xiaomi 15 Ultra. Manual mode. RAW A JPEG FROM ADOBE CAMERA RAW. I will quickly go through the hardware of this phone, since it is exactly what you are thinking: a Snapdragon 8 Elite16 + 512 GB of memory, 5.430MAH battery and a 6.73 OLED 2K (3,200 x 1,440) screen with a 3,000nits peak brightness and a PWM Dimming of 1,920 Hz, quite high. It is early to give conclusions about autonomy and performance, but I already anticipate that at the hardware level it will be difficult to give it too many ear pulls. The only one is its battery, of 5.410mah. It is not a bad capacity, but the Chinese model has 6,000Mah. There are several manufacturers that, for some reason, are bringing to Europe telephones with less capacity. Bad news for us. An inch sensor. Teleobjective 4.3x of 200 MP, second telephoto and ultra wide angle of 50 MP. I’m starting to salivate The key to this phone is the camera, and it is that it opens a brutal Teleobjective with a 200 megapixel sensor And a 1/4 “size. The main sensor, one more year, is Sony Lyt-900, a beast of an inch. The lenses have been redesigned and the coating of them has been improved, promising to avoid reflexes. This according to Xiaomi is especially important in night photographs, where the reflexes can end the photograph. It is today, The smartphone with the highest hardware potential on camera to date. He is accompanied by an optical teleobjective of three increases of 50 megapixels, a new teleobjective of 200 megapixels with Zoom 4.3x and an ultra wide angle, also of 50 megapixels.

This man is the first person who flies to space without revealing his identity. They haven’t taken to find out who it is

Six people traveled yesterday to the Blue Origin suborbital rocket. One was Jesús Callejathe first television presenter that crosses the line of Kárman as part of the filming of a documentary. In the same ship another five people flew. Four of them, millionaire businessmen and executives who had paid for the flight. The sixth crewman was an anonymous person. Was An anonymous person because on the Internet there are difficult secrets to maintain. Context. They are already going 52 people That they fly to the space with Blue Origin since Jeff Bezos, the owner of the company, premiered the small New Shepard rocket with his brother Mark, the aviator Wally Funk and the young Oliver Daemen (the oldest woman, with 82 years, and the youngest man, with 18, in crossing the border of the space). Taking into account that just 719 people have traveled beyond the 100 kilometers of altitude, Blue Origin’s space tourists begin to be a multitude in the select club of people who have gone to space. With its flights for millionaires of just 10 minutes, the New Shepard rocket has a growing record of records: the oldest man (William Shatner), the first Mexican (Katya Echazarreta), the first Portuguese (Mário Ferreira), etc. What they had not had until now was an anonymous passenger. The first suborbinaut without name. Of the 719 people who have flown to space so far, none had done without revealing their name. The astrophysician Jonathan McDowell knows it well, who maintains a database of all space flights in historystarting with Yuri Gagarin on April 12, 1961, and Alan Shepard, on a suborbital flight, 23 days later. When McDowell went to update his database with the crew of the NS-30 mission of Blue Origin, he decided not to settle for the unknown of the sixth traveler (the first stain of the history) and asked his followers (in a tweet now erased) if they could find out who he was. Most of the answers reproached McDowell having used their influence to try to expose a person who wanted to remain anonymous. Others They wondered If it could be the camera of Jesús Calleja (but why hide his identity, then?). Until, finally, one of McDowell’s followers found who he was. R. Wilson. Blue Origin had diligently complied with his client’s desire. The mysterious traveler He went out to face discovered In the official photos and videos of the mission, but on the web, on social networks, in the press releases, in the retransmission of the launch, Blue Origin only mentioned the first five passengers with name and surname, adding: “and a sixth crewman whose name has not been revealed.” What did not help the man to preserve his identity was to have his initial and his last name embroidered in the space suit: R. Wilson. However common the last name Wilson was enough to French YouTuber Ufotinik He will find his full name and news about him on the Internet. An Australian cryptocurrency. Jesús Calleja mentioned in an interview that an Australian friend had done on the mission. Perhaps he refers to Russell Wilson, founder of the Coinspot cryptocurrency exchange platform, based in a modest Melbourne building. According to a report of 2023 of the Daily MailWilson leads a discreet life in the city’s suburbs, although he has paid 538 million dollars in dividends. The report includes a photo of the businessman, who already maintained a low profile and avoided public attention, delegating media appearances in his executives while led the company from anonymity and following strict security protocols. He failed to maintain anonymity then, nor has he achieved it on his trip to space. But McDowell’s efforts for not letting an entry into its database only reinforce the initial idea of ​​this article: space tourists are beginning to be a crowd in the select club of people who have gone to space, so we will see more and more eccentricities above the karm line. After all, career astronauts, those of space agencies, are officials chosen and formed to the extreme for a single thing: act according to the protocols and be predictable in any situation.
