Today at Lidl this ice making machine that will save you from buying bags in supermarkets or gas stations this summer

by

Although there are still a few days until summer officially begins, it is already hot almost everywhere. Whether we are alone at home or when a visitor comes, having ice cubes in the freezer becomes almost essential to have cool drinks. But this one ends and the molds that we all have in the freezer are not always enough (plus they take a long time to do their job). We have an alternative to avoid this with the ice cube machine that Lidl has: it is from the Silvercrest brand and costs 62.99 euros. Ice cube machine 105W The price could vary.

the problem was never the nuclear bomb

by

In October 1973, during the first great oil crisisgas stations in the United States posted signs “Sorry, last car in this line” to cut kilometer-long queues and ration fuel. That image became the symbol of an uncomfortable truth that remains valid half a century later: when energy is what gets stuck, even the great powers change their priorities. The end of a war with another truth. For more than a hundred days, Donald Trump sold the war against Iran as a crusade to prevent Tehran from crossing the nuclear line. The rhetoric was clear: unconditional surrender, dismantling of the atomic program and maximum military pressure. But the agreement that now it just closed with the Iranians reveals another, much more uncomfortable reality: the priority was never really the bomb. In fact, if it had been, Washington would not have accepted a pact that leaves the regime intact, postpones nuclear negotiations and turns the issue of enriched uranium into an issue. for later. What was urgent, what was truly unbearable for the White House and the markets, was something else: reopen Hormuz. The neck of the world. we have been counting these months. The Strait of Hormuz became in the royal center of war because about a fifth of the world’s oil and gas passes through there. When Iran closed it de facto, it not only paralyzed regional exports, but turned the conflict into a systemic threat for the global economy. Oil skyrocketed, gas followed suit, and markets began to discount something much more dangerous than a regional war: a global energy crisis. Trump could continue bombing and wasting ammunition (maybe too much), but each day that Hormuz remained blocked it more damage to Washington than to Tehran. The weapon that Iran did have. For years there was discussion about the hypothetical iranian bombbut in the end Tehran’s real pressure capacity was not underground in those missile cities in Fordow or Natanzbut floating over the Gulf. Tehran demonstrated that it could cut off the planet’s energy artery and keep it closed long enough to bend American strategic logic. Therein lies possibly the great lesson: because it did not need to manufacture a nuclear weapon to acquire deterrent power. It was enough for him control a chokepoint vital and show punitive capacity against US bases and regional allies. That changed the entire balance of the negotiation. The economy and its cracks. While the war continued, the world began to consume strategic reserves at a worrying speed. The United States drained its so-called Strategic Petroleum Reserve to levels not seen since 1983, Japan and South Korea saw reduce your inventories and Europe was beginning to strain its refined fuel supply chains. It is true that there was no collapse yet, but there were clear signs of fragility and that we were approaching red lines. In other words, the market continued to function thanks to these “shock absorbers”, but everyone knew that they were finite. Because the war could continue, but the energy cheap No. The agreement that reveals priority. And then it has arrived the unthinkable pact when the United States launched its bombing campaign. Sixty days of ceasefire, gradual reopening of Hormuz, withdrawal of the US naval blockade and temporary permission for Iran sell oil again. The sequence is revealing: before resolving the nuclear program, Washington has resolved first the flow energetic. Next will come talks on uranium, if there are any, oversight of the International Atomic Energy Agency and possible sanctions relief phases. That is to say: the nuclear issue is still important on paper, but it was no longer the strategic urgency dictated by the clock. An imperfect peace, but necessary. There is no doubt, the agreement It doesn’t close the wound. Benjamin Netanyahu keep hitting to Hezbollah day in and day out, and the Lebanese front can vturn everything back on. Iran maintains its regime, its regional influence and much of its negotiating capacity. But the war has made one conclusion brutally clear: When the stability of the global energy system began to falter, Washington downgraded its maximums to minimums. In the end, the “bomb” was the political argument, oil was the real problem. And when crude oil began to run out, peace stopped being an option and became an imperative necessity.

We thought the MacBook Neo was the perfect affordable computer. AMD claims it has a big problem: games

by

He MacBook Neo has been everything a missile on the waterline of the “affordable” Windows laptop market. Our analysis confirmed our expectations and we were able to verify that we are facing a more than solvent team with a outstanding price/performance ratio. However, it is not perfect, and its Achilles heel is in a specific area: video games. AMD strikes back. The company has launched an aggressive advertising campaign with a strong message: “The competition makes sacrifices. You don’t have to make them”, and then focus on how the Apple team falters in a section that is important for a notable sector of users: “While 15 of the top 20 PC games don’t run natively on the MacBook Neo, AMD systems give you access to a massive library of games across Steam, Epic Games Store, and PC Game Pass.” The hateful comparisons. In that campaign AMD compares the HP Omnibook X Flip with an AMD Ryzen 5 220 with Apple’s MacBook Neo. It boasts of its 512 GB SSD (256 GB in the Apple model indicated, although there is a 512 GB version), its touch screen and its greater connectivity options. Beware of AMD’s message. As noted in Tom’s Hardware, this AMD chip is not new, but rather a version derived from the 8540U that is accompanied by an integrated Radeon 740M GPU. It’s a modest chip that can run titles like GTA V at 100 FPS in low quality, but Hellblade 2 runs at 8 FPS and Alan Wake 2 runs at 11 FPS. So it may indeed be able to run those video games, but it’s not clear that they are actually “playable.” One thing is certain: the MacBook Neo is not for gaming. In reality, Apple does not focus its MacBook Neo on gamers, because it knows that although the A18 Pro is a truly remarkable SoCis not designed for that sector. The company has its Metal API to be able to run games and it is even possible to enjoy some native ones with some joy, but if what you want is to play (especially with top PC titles), the MacBook Neo is not your device. The laptop war for students. This counterattack from AMD is to be expected: the company has undoubtedly been affected by the enormous success of the MacBook Neo, and is trying to demonstrate that its proposals are just as valid or even better. The juicy niche of student laptops is at play here: if you convince a young person to opt for a MacBook Neo, they will likely end up trapped in the Apple ecosystem (if they weren’t already). Intel also reacts. Intel’s response to the MacBook Neo has not been an advertising campaign, but something much more tangible. The company has announced its platform Wildcat Lakechips made with 18A photolithography that are a priori up to 21% more powerful than the A18 Pro. Equipment like the Chuwi Unibook (from $449) are better at least with the specifications sheet in hand, but its real performance is for now an unknown and we will have to wait for independent analyzes. More options are coming. The Computex fair that took place two weeks ago also made it clear that other manufacturers they are going to try to take advantage this moment of uncertainty to sneak in their proposals. Qualcomm launched its Snapdragon C and Nvidia made something similar with their RTX Spark (we will see the prices). What is clear is that the launch of the MacBook Neo has awakened a segment that had become comfortable, and that is good: there will be a lot of competition and, above all, many options.

that of technological sovereignty

by

The latest Anthropic model, Fables 5it’s amazing. That is, at least, what we know thanks to the evidence we have been able to see. Because one thing happens: Anthropic has deactivated Fable 5. In response to a order of the United States that dictated that Anthropic must suspend access to these models for any foreign citizen inside and outside the country, the AI ​​company turned off Fable 5 and Mythos 5 completely last June 12. Europe has not been slow to respond, but it is really great for keep pushing your message. That of technological sovereignty. In short. That Anthropic and the United States are not on a honeymoon is evident from the mess with the Pentagon and the Department of Defense, but what happened in these last few hours goes one step further. Citing national security concerns, the United States issued an export control directive to suspend access to Fable 5 and Mythos 5 to any foreign national, whether inside or outside the United States. This is already serious, but in addition, the company states that it is something that includes Anthropic’s national employees. In response, the company disabled the two models to ensure that that order is met. The United States’ motivation for giving the order was that they had discovered (or that Amazon had informed them about it) a bug in Fable 5 that allowed ‘jailbreaking’ the model, a vulnerability that Anthropic reviewed and which they believe is also in other publicly available models. Europe responds. Beyond the repercussion for the company, it is something more serious: once again, the United States dictating what a citizen of another country who pays (or who does not pay, because right now it is in the free trial phase) can and cannot do a product from a private technology company. And this has been great for Europe to continue strengthening its position on technological sovereignty. The European Commission has not been slow to position itself, stating that it is evaluating the practical implications of the export control directive implemented on Anthropic, pointing out that the measures should not be discriminatory against partner countries. Commission spokesperson Thromas Regnier points out that, while the new generation of AI models offers advantages for cyber defense, it also raises cybersecurity concerns. “This episode is another example of why Europe needs to strengthen its technological sovereignty” – Thomas Regnier, spokesperson for the European Commission However, he considers that contingency measures should not be discriminatory against partners and takes the opportunity to remember the European position of recent months. In the statement, Regnier states that the Commission is “closely examining the practical consequences of this measure for European users” and concludes by reinforcing the message of technological autonomy: “this episode is one more example of why Europe needs to strengthen its technological sovereignty.” Sovereignty. This term will be one of the star words of this year because recent events are leading several countries to strengthen their own ecosystems. The United States has the big technology companies, but China has already put its plan to become the leading world power on the table. And Europe has arrived later in the race, but has gotten fully into it. With the threats of the United States of leave NATOhe Donald Trump’s aggressive language against allied countries and the dependence on American technology like SpaceX In the war between Ukraine and Russia, Europe has realized that it must change the chip, betting again on technological infrastructure. That includes from chip development to its own AI models, through the rearmament announced last year and the boost to the aerospace arm. Slow independence. Beyond the message from the European Commission, other parliamentarians have pronounced about it. Aura Salla, MEP for Finland, pointed out that “Europe cannot continue to increase its technical potential by relying on access that can be cut off by a foreign government overnight”, reinforcing that European message. own The New York Times A few days ago, he echoed the European plan to reduce dependence on American technology, alluding to the tense relationship with the Trump administration and mentioning that 80% of the digital products, services, infrastructure and intellectual property of the countries of the Union depend on companies such as Amazon, Google and Microsoft. Now, these changes, unlike turning off a model like Fable 5, cannot be made overnight. They are slow and require a complex resilience process that, however, can be accelerated driven by actions such as those taken last Friday by the United States.

NASA has a plan to solve one of the biggest mysteries in the cosmos and only one thing is missing: money

by

Since the first confirmed discovery of an exoplanet in 1992, there have already been discovered more than 6,000 planets beyond the Solar System. Although there are many of them, and they have very specific characteristics, there is something that unites them all. Which can have a radius smaller or larger than 1.8 times the radius of the Earth, but never that. It is like a border that can be crossed or not, but that is never stepped on. The exoplanets that are below that limit are the super earths and those who are above subneptunes. It is not known what causes this gap, but there are two hypotheses. To confirm which of them is the good one, NASA has designed a mission. The problem is that he still hasn’t gotten funding for it. In search of young planets. The two hypotheses that exist about the origin of this gap are related to the origin of exoplanets. Therefore, the best way to unravel the mystery is to analyze young planets. The problem is that this is not easy. Of the 6,000 exoplanets that have been discovered to date, only 20 were younger than 50 million years. The objective of the Early eVolution Explorer (EVE) mission is to launch a ship loaded with probes specialized in detecting exoplanets around young stars. If the star is young, the planets around it must be young too, since the planet always forms after its star. Very different exoplanets. Super-Earths are rocky planets, with a radius less than 1.8 times that of Earth. They are closer to their star than the sub-Neptunes, which are also larger, with dimensions above the prohibited radius. On the other hand, sub-Neptunes have a less rocky, more spongy appearance. The first hypothesis. As we have anticipated, there are two hypotheses about the forbidden radius of exoplanets. The first points to the same origin. Supposedly, all exoplanets were born with a rocky core that dragged clouds of hydrogen and helium around it for millions of years. The difference between them would be that the super-Earths, being closer to their star, would receive more radiation, so the gas layer would end up being destroyed. The sub-Neptunes could preserve it, hence that spongy appearance. The second. As for the second hypothesis, it points to the possibility of planets clinging to water during their formation or not. Super-Earths are located between their star and what is known as the snow line. This is a line above which water can freeze. In this case, not only does it not freeze, but the water receives so much heat from its star that it ends up evaporating. If water is in the form of vapor, it cannot join the “pieces of the nascent planet.” That leaves them only made of dry rock. On the other hand, the sub-Neptunes are further from the snow line. Water can freeze, so it becomes bricks that can be incorporated into the planet in formation. It is bigger, because it not only has rock, it also has water. Furthermore, that water condensed around it gives it the cottony appearance that makes it different from a rocky planet. Artist’s concept of an aquatic world The handicap of young stars. We have already seen that to unravel the mystery of the forbidden radium we must study young planets. We have also understood that the best way to do this is to look around at young stars. The problem is that these have such intense activity that fluctuations in their brightness can occur. associated with flaresnot an exoplanet orbiting it. In short, many false positives can occur. Three sensors. To solve this problem, EVE would be equipped with three sensors. The first analyzes light in the near ultraviolet, the second in the visible light range and the third in the near infrared. The first is used to detect bursts from the star itself, since these emit great radiation at that frequency of the spectrum. Regarding the second, it is the type of light that is normally used to detect transiting planets, the most used tool for the detection of exoplanets. Finally, young stars emit a lot of light in the near infrared. For all this, if a peak is detected in the near ultraviolet we will know that it is due to the activity of the star itself. If we see fluctuations in visible light we will understand that there may be a planet orbiting the star; But, to be sure, we must compare the data with the light emitted at all times by the star itself. That’s what near infrared is for. The forbidden radio. By studying young exoplanets, we can know how their formation was and understand which of the two hypotheses is the good one. With this, in passing, we will understand why the radius of 1.8 radii of the Earth is prohibited. 30 star cluster fields, 30 days. The EVE project has been planned to analyze 30 fields of young star clusters for 30 days each. Thus, more than 20,000 young stars could be analyzed and, with them, possible exoplanets of recent formation could be found. At the moment, it cannot be done, because the project does not have financing, much less a launch date. But NASA has everything tied up. You just need that little push to unravel the mystery.

so that the software still fits on a floppy disk

by

We have become accustomed to software weighing more and more. We see it in applications that take time to download, in simple tools that come with too many layers and in services that promise convenience in exchange for take up more spaceconsume more resources and depend on more invisible parts. That is why it is striking that, in 2026, when much of the technological conversation revolves around AI and increasingly ambitious systems, there are those who claim an idea that seems to have come from another era. The initiative is called Fits on a Floppy and part of a manifesto published by developer Matt Sephton. Its rule is as simple as it is striking: an application that wants to show off its badge must have a total download size of less than 1.44 MB, the capacity of a classic 3.5-inch floppy disk. The text itself summarizes it with a direct phrase, “the software has lost its way”, but its proposal is not to miss the physical support, but to recover the discipline that was imposed by working within very narrow limits. For a long time, making software was also about giving up. If something was not necessary, was left outbecause memory, storage and user patience had a very visible limit. Then came a different stage: the teams they began to have more margindownloads stopped feeling like an adventure, and the size of an app stopped being a central concern. There a dangerous door began to open. The software has not gained weight by accident Not all of that growth came from adding visible features. Much of it came underneath, in the form of layers that the user does not always see: libraries, engines, update systems, components designed to support more than one version of the same product and dependencies that allow progress to be made faster without solving each problem from scratch. That way of building makes sense in many cases, especially when you want to maintain the same product in several systems. But the scale also changes. This is where the real value of Sephton’s proposal comes in. Fits on a Floppy is not trying to show that everything should be compressed to fit into 1.44 MB, but rather that an artificial restriction can serve to prioritize. If an app is born to solve a specific task, the manifesto asks that it download quickly, start without waiting, consume few resources, be native and avoid unnecessary dependencies. The underlying idea is simple: the less baggage a tool carries, the easier it is to understand what it does, why it does it, and how much it costs to maintain it. The question, then, is whether this discipline can once again have a journey outside the manifesto. In some software, probably yes. We are not talking about browsers, video editors or services with integrated artificial intelligence, but rather small utilities, single-function tools and native applications that often do not need to carry a huge architecture. There Sephton’s argument is stronger: if the objective is limited, the size should also be limited. Not out of nostalgia, but because a simple tool has fewer excuses to behave like a full platform. The other side of the story is that much of the software is not going to get smaller. Many current applications are no longer just a window with a specific function: they integrate accounts, synchronize data, offer real-time collaboration, work on multiple systems and they accumulate functions that were not part of a desktop application years ago. All of this may be justified, but it weighs. That’s why the promise of returning to lightweight software has clear limits. For many products, the real question will not be whether they can fit on a floppy disk, but whether they are growing out of necessity or accumulation. The beauty of the floppy disk, in fact, is that it no longer seems reasonable. Precisely for this reason it forces us to look at the software from another place and ask ourselves if all that weight responds to a real need or to an accumulation that no one dared to review. Fits on a Floppy is not about stopping the evolution of modern tools or denying that many need to be big. Its usefulness lies elsewhere: reminding us that efficiency is also a design decision, and that the size of an application says something about how it was intended.

apps that don’t sell anything

by

There are few guilty pleasures as satisfying as online shopping: that exciting moment of searching until you find what suits you best and then put it in the cart. You’ll enjoy it later, when it reaches your hands. Or not, because in reality the process itself is almost more enjoyable than the product in question. Not to mention something obvious: to buy you need to have money in your account and not need it for other purposes, such as paying rent or eating. If you can’t afford the real experience, South Korea’s youth has found a way of tricking the brain into releasing that dopamine from shopping: apps that sell nothing. Fake it until you make it. What is happening. He Korean Times collects the phenomenon of dopamine sites and its operation in two types of apps: those for food delivery and those for smoking breaks, in which you have a virtual cigarette with other people with that banal conversation typical of the occasion. Thus, you can consult menus, select items to add to the cart and know delivery times or restaurant ratings without closing the transaction. And you can also say, if you prefer, something like “Tuesday, you’re sick of shit” in a virtual room. Kim Heon-sik, a professor at Jungwon University, connects these apps that do not sell anything with the culture of Muk Bangin which people watch other people eating tremendous amounts of food. Curiosity, voyeurism and satisfying the gluttony of whoever is on the other side of the screen without having to put anything in their mouth. The vicarious satisfaction at its finest. Tap to go to the post Why is it important. On the one hand, these dopamine sites function as a snitch on the mental health of a generation: in South Korea, digital exhaustion and smartphone dependence are already public health problems. documented with a star risk factor: anxiety. On the other hand, they reveal a disconnection between two worlds: the economic and the neurological. Delivery and ecommerce apps have been refining their interfaces and experience for years to enhance the impulse to buy: infinite scrolls, exclusive offers for a limited time (spoiler: they never end), incessant dripping of notifications… the “technology of persuasion” that coined Tristan Harrisformer Google designer. The result is that according to neurosciencedopamine is released in anticipation, not upon receiving the order. Dopamine sites do exactly the same thing, but at zero cost, something ideal for a generation that cannot afford that expense. Context. That deliberate design of apps and the release of dopamine can lead to a shopping addiction… if you have the money. The point is that Korean youth do not have it: a recent report from Bank of Korea portrays their dangerous situation. Every year that a young person spends without work reduces their future salary by 6.7%, their debt has increased and the proportion of them living in precarious housing went from 5.6% in 2010 to 11.5% in 2023. OECD confirms that the Korean youth employment rate is below average and that they practically wait in line to access large companies or the public sector. This structural problem already has a name: Sampo generationwhich refers to the three renunciations of this youth, love, marriage and being a father or mother, caused by unstable jobs and high educational debts. In detail. The psychological mechanism behind those apps that sell nothing It is well documented: The brain does not distinguish well between the process of asking for food and the simulation of asking for it, so dopamine acts mainly in that search and anticipation phase, not when receiving the reward. That’s why the fake app works: it gives the reward system what activates the process without having to swipe the card. Regarding smoking break apps, more of the same: this study on loneliness in Korean adults found that those young people most exposed to the digital environment reported significantly higher levels of loneliness than previous generations. Seeing that there are more people online at the same time, even if they are complete strangers and you don’t talk to them, activates the feeling of social presence, which reduces anxiety. Yes, but. The Korean Times report echoes few testimonies about this phenomenon, but there is no data on how many people use these apps or how frequently. Even if it were a trend, the million-dollar question is what effect these apps that sell nothing have: it is true that they have no impact on the wallets of those who use them and that they occasionally provide relief, but also that they do not help solve the problem behind: anxiety, loneliness and dependency linked to a precariousness of their life expectations.

“If you’re still awake twenty minutes after going to bed, get up.”

by

Going to bed and starting to toss and turn while watching all the early morning hours pass by on the clock is something that may be familiar to more than one person. Right now, the truth is that the simple act of closing your eyes tightly and thinking about falling asleep doesn’t work too muchbut it further increases anxiety and frustration due to not being able to be rested the next day. But here the experts suggest that it is better to get up. A simple rule. Beyond breathing techniques and treating a blank mind, we have a good ally with us: the “20 minute rule.” A practice that, far from being viral advice on social networks, the truth is that it has scientific support behind it that indicates that the best strategy against the inability to fall asleep is to get up. Its operation. To understand it, we must first descend to the substrate of associative learning, where the human brain is, above all, an optimizer of environmental patterns. In this way, when a healthy person goes to bed, the central nervous system interprets the physical stimulus of the mattress, pillow and darkness as a signal to initiate a transition to sleep. However, if we spend long periods awake in bed experiencing anxiety or having the same idea running through our minds all the time, the pattern becomes corrupted. Here the brain already associates the bed with frustration, and the bedroom stops being a parasympathetic sanctuary and becomes a way to activate our body. Your defender He is currently Dr. Matthew Walker, professor of neuroscience and psychology at the University of California, Berkeley, and director of the Center for Human Sleep Science. And it is so important that he includes it as another piece of advice in one of his published books titled ‘why we sleep’ that says the following: Don’t stay awake in bed. If you’re still awake twenty minutes after going to bed, or if you start to feel anxious or worried, get up and do some relaxing activity until you feel sleepy. The anxiety of not being able to sleep can make it harder to fall asleep. What must be done. To follow the rule, it is important to get up and, logically, not turn on all the lights in the house, but rather use dim lights and, under no circumstances, look at screens such as television since it can activate us more. The ideal here would be to read a somewhat monotonous book (or in the case of students, notes), do breathing exercises or mechanical hobbies. From here you should return to bed only and exclusively when you feel sleepy again to try to sleep again. The guides say it too and, more specifically, the Clinical Practice Guide on Insomnia in Primary Care which specifically points to the following advice for patients: If it’s been 30 minutes since you went to bed and you’re still not sleeping, get out of bed, go to another room, and do something that doesn’t activate you too much, like reading a magazine or watching TV, for example. When you feel sleepy again, go back to your bedroom. The goal is for you to associate your bed with falling asleep as quickly as possible.

the impossible fighter “Christmas tree”

by

In the summer of 1955, Nevadans began reporting strange objects flying at impossible heights. Decades later, declassified CIA documents revealed that a large part of those supposed UFOs were actually secret prototypes that were tested at Groom Lake, the facility that would become known worldwide as Area 51. A blurry image and a forgotten idea. It all started a few days ago with a thermal capture taken near Groom Lake, the facility better known as Area 51. The image showed an oddly shaped aircraft, apparently tailless, with large front canards and unconventional wings. The video quality makes it impossible to identify with certainty what exactly it is, but it was enough to trigger a avalanche of theories. The most striking thing is that the silhouette has led several specialists to rescue an idea that seemed buried for more than forty years: an experimental stealth fighter concept designed in 1983 that received the informal nickname from “Christmas Tree Fighter” or Christmas tree hunting. Thermal image appeared near Area 51 The return of the impossible fighter plane. That 1983 design was created by Darold Cummings, one of the engineers who would later participate in the development of the YF-23. At the time, Northrop was looking for radical ways to build a fighter jet with an extremely reduced radar signature. cummings proposed the DP-21an aircraft with such extreme geometry that many considered it impossible to fly. Its configuration sought to achieve a highly coveted feature in stealth design: a structure of only four large main radar reflections, something similar to what was achieved by the B-2 bomber. The problem was that the flight control technology of the 1980s couldn’t safely handle a device so unstable. That’s why the concept was shelved as a technical curiosity rather than a real project. “Christmas tree” fighter project Why has a photo aroused so much interest? The aircraft observed near Area 51 presents some features that vaguely remember to that DP-21. Particularly noteworthy is the shape of the front section, which in certain images seems to draw a kind of double arrowhead. The absence of traditional tail surfaces, the presence of large canards and a general distribution of wings and fuselage that departs from conventional designs also coincide. Nobody claims that it is a direct evolution of the Cummings projectbut the comparison is inevitable because the image seems to recover aerodynamic solutions that for decades were considered too complex or risky to become an operational aircraft. The clues point to the F-47. The dominant theory is that the aircraft could be related to the technological demonstrators of the NGAD program, from which the future F-47 United States. The general shapes match several elements visible in the few official designs published so far: large canards, very set back wings, absence of vertical stabilizers and a configuration optimized for stealth. Furthermore, some researchers have pointed out that the silhouette appears to have been hidden in plain sight for years. An official patch from the office responsible for the F-47 included a stylized figure that, upon closer inspection, striking similarities with the device captured in the thermal image. It wouldn’t be the first time a top-secret program leaves seemingly innocent visual clues. on insignia and emblems internal. Decades of hidden experiments. The possible aircraft also appears to draw influences from other experimental programs developed by Boeing and its predecessors. Among them the X-36 stands outa tailless demonstrator designed to explore new forms of maneuverability, and the Bird of Preyone of the most secret projects of the nineties. Both opted for extremely unconventional configurations and to reduce the radar signature as much as possible. They remembered on TWZ that the technologies tested in those programs never really disappeared, but continued to evolve within classified projects. The catch obtained near Area 51 could be the first public evidence of how far that evolution has come. An unsolved mystery. The reality is that no one outside the most restricted circles of the Pentagon knows what exactly it shows the recording. It could be an F-47 demonstrator, a prototype related to the future F/A-XX naval fighter, a Northrop Grumman project, or even a completely different experimental platform. The only thing evident is that the image has achieved something unusual: bring an idea to the foreground born in 1983 which many considered a footnote in aviation history. Forty years later, the supposed “Christmas tree hunt” is relevant again because a shadow caught in the Nevada desert sky seems to suggest that some of the strangest ideas of the past may have finally found the technology needed to become a reality.

A macro study confirms that early menopause increases the risk of heart attack and stroke

by

When we think of the menopausesocial and medical conversation is usually limited to obvious and short-term symptoms, such as hot flashes, mood swings, insomnia or the closure of the fertile period. However, this phase in the life of any woman has implications that go much further in terms of health as it involves a great metabolic and, above all, vascular change. A new vision. Now, the largest international study carried out to date has confirmed a reality by pointing out that when menopause comes early, the risk of suffering a myocardial infarction or stroke increases drastically, remaining stable independent of other traditional risk factors. The magnitude of the study. The research, to reach these conclusions with practically unwavering solidity, has resorted to the PURE-based macro-study, closely following a massive cohort of 111,619 women from 26 different countries, recording their clinical evolution for an average of 14.6 years. And the experts already point out that we are facing a methodological turning point in female cardiology. In figures. The findings evident in this study clearly segment the risk based on the age at which the end of menstruation occurs: When menopause occurs before the age of 40, it is called ‘premature menopause’ and carries between 27% and 30% greater risk of suffering major cardiovascular events such as heart attacks. In the case of a menopause between 40 and 45 years of age, it is called ‘early’ and registers a 14% higher risk of presenting cardiac complications. It is a risk factor. The most robust and worrying data provided by the research is that this increase in cardiovascular risk persists practically unchanged even after the researchers statistically adjusted the models to isolate some classic variables such as high blood pressure, diabetes, smoking or a sedentary lifestyle. This means that early loss of ovarian function is an independent risk factor in itself for these serious problems to occur. Because? The medical explanation behind this phenomenon lies in the abrupt loss of what cardiologists call the “estrogen shield.” It must be kept in mind that during the fertile age, estrogenic hormones exert a fundamental protective role in the circulatory system through various mechanisms, such as keeping cholesterol and triglyceride levels at bay. But estrogens also keep veins and arteries in good condition, promoting vascular relaxation and inhibiting the accumulation of body fat in arterial walls. Additionally, when estrogen levels fall prematurely, the process of forming lipid deposits in the arteries progresses at a much faster rate. The economic gap. One of the most innovative and alarming points of the PURE study is how the geographical context radically alters the impact of early menopause. And its conclusions show how the impact on cardiovascular health is almost double in low-resource countries compared to rich nations. For example, in countries such as Pakistan, Tanzania, Bangladesh, India and Zimbabwe, an overwhelming 43% of postmenopausal women had experienced early menopause. But in rich nations like Canada or Sweden the figure drops to 23%. A nuance. The authors introduce an important warning, since in countries with very precarious economies, chronic malnutrition usually causes what is known as hypothalamic amenorrhea, since the body prioritizes living over maintaining other functions such as reproductive functions. And although this confusion could partially inflate the statistical gap between rich and poor countries, the study clarifies that it does not in any way invalidate the main conclusion of the study: on a global level, without estrogen, the heart suffers.
