China has a key technology to create a more effective antimisile shield than the iron dome: a beetle

During the recent one Conflict between Israel and Iran There was a lot of talked about the powerful Israeli antimile defense system, known as the ‘Iron dome’. Europe too wants to build yours and United States shuffled the creation of a ‘golden dome’ that would use a satellite network and would be able to Stop hypersonic missiles. And what about China? Although they have Several antimile systems At different levels, they do not have a “total” shield like the one who wants to build the United States. What they do is a technology that, if applied, would far exceed the detection of missiles from other countries. A beetle. This kind of beetles receives that name for its ability to detect fire up to 80 kilometers away Thanks to an organ in its most sensitive exoskeleton than most infrared sensors in the market. This has been the inspiration of these Chinese researchers for their new creation: a system that mimics this same sensitivity and allows you to detect hot objects quickly and precisely. The system. During the investigation, Posted in Nature magazinethe scientists carried out several tests to verify the effectiveness of the system. In the first they built an ‘heteroestructure’ with divel -divelur, a material that offers a high absorption of the middle infrared range, and pentacene, an organic semiconductor. The device could detect radiation to an intensity of only 0.5 millivats per square centimeter, a sensitivity close to that of the beetle. In the second test they used black phosphorus and Indian seleniuro, achieving a photonic memory of 0.5 microseconds, 20,000 times faster than conventional optical storage. Capacities. Researchers affirm that this technology is able to “detect and identify objects in difficult environments, since it can penetrate obstacles such as smoke, fog and dust, providing clear images and precise detection of objectives.” In addition, it works at room temperature without refrigeration. This technology could be used in various scenarios: fire detection, autonomous driving, night vision systems and of course military environments. Antimisiles. As we said, China does not have an “dome” antimile system, but this technology could open the door to the creation of one that, According to South China Morning Postit would be much more precise than the ‘Golden Dome’ that Donald Trump wants to build. The key point is that the system integrates detection, memory and processing functions. Current antimisile systems are based on traditional silicon semiconductors and hardware separation (sensors and processors) prevents them from reaching those response speeds. Nothing concrete. Donald Trump’s ‘golden dome’ is, for now, a proposal that has not yet materialized, just like this hypothetical Chinese dome. What we do know is that China did not make any grace The announcement of this project because “it would raise the risk of converting space into a war zone and creating a career for creating space weapons.” Currently, China has several antimile defense layers: Dong Neng-3an exoatmospheric missile interception system, HQ-19 for medium-range interception and HQ-29 with antisatelite capabilities.

The heat arrives and you want to drink cold water. Science has a much more effective idea: drink hot water

Summer arrives and with it staying well hydrated becomes an imperative. The heat will surely make a glass of cold water even more appealing, but it is likely that we have ever heard that the water, better hot. Is it a myth or is there a reason behind? Drink water. Drinking water is the important, hot or cold, keeping our body hydrated is the main objective. Despite this, drinking hot water or cold water is not exactly the same: our body can react differently Before the stimulus. This is what science tells us about it. Better digestion. Hot infusions are a desktop classic. Coffee, tea or chamomile are usual choices to close the food, especially if it has been copious. When consuming these drinks we are, indeed, Drinking hot water. In doing so we are moisturizing our body and allowing water to help the flow of food in our digestive system. Part of the effect we owe it to the mere fact of being drinking water, but there are some studies that suggest that the temperature could play an important role in the digestive effect of this desktop habit. A Study published in 2016 Focused on newly operated patients, he observed that the consumption of hot water in recently operated in the colon had a “positive impact” on subsequent intestinal movements. Do you lose weight drinking water? In 2023, a group of researchers conducted An experiment in which a group of participants had to consume a certain amount of warm or hot water after meals, while the rest had to consume the same amount of water at a temperature without specifying the temperature. As reported by the team, the group that consumed hot water lost body mass more speed than the control group. This could explain why we associate drinks such as tea are associated with weight loss. The diuretic potential of some infusions and the benefits that others have on intestinal transit could be related to the mere act of drinking hot water, but the truth is that the tests we have are very limited, so we still cannot add the hot water to the eternal list of candidates for “miracle diet”. Cool ourselves with hot water. It may seem Little appealingbut hot infusions are a classic in some of the most scorching environments in the world. Our body is about 37º Celsius: if we consume something at a higher temperature, our body will absorb that heat. It doesn’t seem like a good plan. And yet it works (although not always). The key, The experts point outis how our body dissipates heat through sweat. A hot drink can activate nervous receptors by sending the signal that the temperature is greater than what is actually, which in turn does that our body begins to sweat and thus begin to dissipate heat through the water we expel by the skin. To sweat, of course, it should also be hydrated. When may not work? Drinking hot water to reduce our body heat can be a bad idea in some contexts, mainly When moisture is high. Moisture makes sweat dissipated, with it, avoiding it heat. Temperature and hydration. Hot or cold, we began by saying that the most important property of water is that it hydrates: our body needs this liquid to stay alive and drinks are the main source to obtain it. Now, we know that Not all drinks hydrate the sameDoes the water do it indistinctly of its temperature? Maybe not. A Study published in 2013 He calculated how the water temperature affected the rehydration process. A too hot water could induce sweat, causing us to lose some water at the same time we rehydrate. By contrast, water too cold or too hot can also make us drink less. The team observed that a better rehydration was achieved when consuming fresh water, about 16º, a temperature similar to that offered by tap water.

Obssing with losing weight is a very bad idea to lose weight. Luckily, science has many more effective

A young doctor appears before his boss and, although he does not say it out loud, he thinks “the last time I was in front of him, I swept at least a liter. But now I’m going to sweat at least ten, that guy will find out what is to sweat!” Then, do not sweat a drop. It is not fiction, it is A real case collected by psychiatrist Viktor Frankl In 1994. He did to explain that many times our fears, objectives and intentions play against us. And yes, we are talking about losing weight. Against us? It’s as if, for using A metaphor of another psychologists (Steven C. Hayes)“We fell into a deep hole and the only thing we had to go out was with a shovel. As we don’t know very well what to do and we despair, we started using the shovel.” The result, despite working day and night, is that we are deeper than before. What in the background tells us a good number of psychologists (from Logotherapists to Specialists in acceptance and commitment) is that we are so culturally attached to certain behavioral strategies that, although they are not useful, we cannot get rid of them. The obsession with “losing weight” is a problem. And yes, obsession is the word. In Spain, where 52% of the adult population presents overweight or obesity, seven out of ten people (72%) They have tried to lose weight at least once in their life. In fact, According to the Mapfre Foundation datathey have done it, on average, about seven times. That leads to “53% of Spaniards has ever followed a popular or miracle diet with the aim of losing weight.” It is not an accident; It is the consequence of what I commented: in the popular imaginary, the way of losing weight is that. That is to say, In words Giuseppe Russolillopresident of the Spanish Academy of Nutrition and Dietetics, “the population is not fully aware that the methods that use weight losing are extremes and can put their health at risk and that the recovery of the lost weight is frequent.” And what can we do? The first is to banish false myths. Sï, obesity is a health problem; but Not so clear that overweight is in general terms. “The life expectancy of people overweight is not less than that of Normopeso”, He told us Juan Ramón BarradaProfessor at the University of Zaragoza. Many ideas that we have above all this and that we use to justify our behaviors, are still disciplinary stories. That does not mean that health is not important. It means that many of those ideas about overweight, health and beauty are cultural strategies equivalent to getting to cabin being inside a well. So? There are no scientific knowledge that can help us? “From what we can extract from current investigations, there are three tips that can be given to anyone: Eat healthyexercise and Accept your body. Today, everything is reduced to weight loss, “he continued Barrada. Therefore, “we must be clear that stigmatizing people overweight or obesity such as ‘vague’ or ‘lack of will’ is to promote suffering” unjustified. And do it with ourselves too. Luckily, as Barrada pointed out, there is another way of doing things. Image | I Yunmai In Xataka | The scientific reason why miracle diets do not work is
