How to measure the distance between two points in Google Maps on PC and mobile

by

Let’s explain to you how to measure distances in Google Mapsso that you can have better references of how far away the points that interest you are. It is not about measuring distances on roads or paths, for that you can make routes on Google Mapsbut to draw a line between two points and know their physical distance. You will be able to do this to measure streets, roads, or anything you want on the map. A virtual ruler will be generated telling you the distance. We are going to teach you how to do both on the Google Maps website and in the application. Measure distances on the Google Maps website If you are using the Google Maps website, you have to do right click on one of the points of the measurement you want to make. This will open a context menu, where you have to click on the option measure distance that will appear at the bottom. Now all you have to do is click on another point on the map. Come on, you right click on the starting point, and then when you choose the option, click on the final click. This will generate a ruler that will show you the distance between these two points. Now you can continue marking new points that will be joined with the previous ones, and you will be able to see the distance between each of the points. Besides, At the bottom you have a local distance indicator which will tell you the total of the sum of all the distances. Measure distances in the Google Maps app Distance measurement is different in the Google Maps app, since it only shows you the total distance and not point by point. But the way to do it is quite similar. The first thing you have to do is click with your finger on the place on the map that you want to be the starting point. This will open a menu with many options, and in it you must click on the option measure distance that you will have inside at the bottom. Now, there will be an aiming point in the center of the screen, and with your fingers you will have to move until you go pointing to where you want to add new points. When you do, click on the button Add pointand everything will stay the same so you can add new points. At the end, you also have an indicator at the bottom left where it will tell you the total distance that all the points add up.

science points to something that disappears when you roast it

by

The world of nutrition and supplements is full of dizzying promises, with products that make miraculous promisesand few have made as much noise in the last decade as green coffee. Often marketed as the definitive panacea for weight loss, this product has flooded herbalists, pharmacies and supermarkets, making it available to anyone who wants to finally achieve weight loss without much effort. However, behind the intense marketing, there is hidden a biochemical reality that goes far beyond advertising slogans and that justifies part of their effect. Although a priori, when we talk about coffee to lose weight, we can go with the idea of ​​the extreme thermogenic effect or the extreme dose of caffeine that activates our metabolism, the reality is different. Here science has a clear answer about its real benefits, pointing to a specific compound that we sacrifice every morning in favor of flavor: chlorogenic acid. What is green coffee? To understand green coffee you do not have to travel to exotic plantations looking for a rare species that produces this product, since green coffee is purely and simply the coffee seed in its natural state, before being subjected to the roasting process which gives it its characteristic black color. Of course, we normally talk about the varieties Arabica coffee either Coffea canephora. If we put ourselves in the ‘normal’ situation, when we roast the coffee beans At temperatures around 200 degrees, Maillard reactions occur. A thermal process that is responsible for generating the characteristic intoxicating aroma, dark color and deep flavor that we can appreciate so much in the morning cup. However, these high temperatures produce a large destruction of bioactive compounds that can help us a lot in our daily lives. That is why logic prevails above all else here: if roasting degrades the healthiest compounds, then we eat it without roasting. And specifically, the element that is most important to us to preserve here is called chlorogenic acid, a powerful antioxidant ester, which is something that we want to preserve above all to reduce the hated oxidative stress that destroys our cells and accelerates aging. In this way, green coffee preserves the three characteristics of this compound intact, becoming an exceptional vehicle for introducing a series of phytochemicals into the body that gives it very interesting properties to achieve the benefits that we will see later. Properties of green coffee As we have said, the chemical composition of green coffee is a gold mine for pharmacognosy. By not being subjected to the thermal stress of roasting, it preserves certain components intact that make it a product with high functional potential. It has a lower amount of caffeine. Contrary to what intuition dictates, green coffee generally contains less than half the caffeine than a cup of conventional black coffee. This means that its stimulating effects on the central nervous system are much milder, which can be very interesting for those who are more sensitive to caffeine. In this way, by not generating such an aggressive alert peak, your consumers rarely need to apply the 90 minute rule after waking up to have your first cup and avoid cortisol shock. Chlorogenic acid. As we have mentioned before, it is the real star of the metabolic function of green coffee, since this compound formed by caffeic acid and quinic acid has led science to classify it into three main classes and that in green coffee it has a maximum concentration. High antioxidant capacity. Various analyzes of beans from different producing regions, including exhaustive studies on Mexican varieties, have confirmed that green coffee has a significantly higher amount of total phenols and a higher antioxidant capacity compared to its roasted counterpart. Presence of trigonelline. An alkaloid that is also better preserved in its raw state and that, according to various tests, collaborates in the regulation of glucose metabolism. What the science says about green coffee Scientific scrutiny on this product has been intense, especially after the proliferation of low-quality studies in the early 2010s, some of which, highly publicized, ended up being retracted by scientific journals due to methodological flaws. Today, the evidence is much more solid, mature and, above all, realistic. The most comprehensive systematic reviews, such as the one led by Tajik in 2017 that analyzed Nearly a hundred studies, both in vivo and in vitro, agree on a clear verdict: the chlorogenic acid present in green coffee is a powerful bioactive agent with antioxidant, anti-inflammatory and neuroprotective effects. But logically here science puts a brake on marketing campaigns, since green coffee does not produce a drastic transformation nor does it magically “melt” fat or rejuvenate in a snap, but it does improve different biomarkers of our metabolic health. In this way, we are not talking about something miraculous, but we are talking about something protective. Benefits of green coffee From all the scientific evidence, a compilation can be made of what this green coffee is used for on a daily basis and if it is really proven, since these are the benefits that enter our eyes and that they try to sell us to finally pay for green coffee. weight loss It is one of the most popular benefits that allows many people to take the step to start taking it, but the question we must ask ourselves here is: is green coffee really useful for losing weight? Here a study published in 2023 shed light on this issue by evaluating green coffee extract, providing at least 500 mg of chlorogenic acid daily to patients. The conclusion they drew was simply visual, as these patients had a significant, but modest, reduction of approximately 1.3 kg in the participants’ body weight. Another important piece of information was given to us in 2019. a second study which stated that the supplements had no measurable effect if consumed for less than four weeks. However, in long-term clinical trials using extracts with 70% CGA and less than 1% caffeine, reductions in body weight of up to 6% were documented, … Read more

The Artemis II countdown has already begun, but many critical points must still be overcome

by

If everything goes well, humans will return to the moon todayafter more than 50 years without manned trips to our satellite. The Artemis II mission has a two-hour launch window, which will begin at 6:24 p.m. local time in Florida (00:24 a.m. PST). Before that launch the countdown will take place. But not the typical 10-second countdown that comes to mind, but a much longer one that has, in fact, already started. During the 50 hours that the countdown lasts, each of the factors that could make it necessary to postpone the launch are analyzed point by point. Only if everything is fine or can be solved at the moment will we finally see this mission begin, which breaks records and barriers in many ways. Who. The crew of Artemis II They will be very different from those of the Apollo missions. Although all of them were crewed by three white American men, this time there will be more variety. The four astronauts who will go aboard the Orion capsule are Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen. The last three will be the ones that will make the difference, since Glover and Koch will potentially be the first black person and the first woman to travel to the Moon and Hansen the first Canadian to leave Earth’s orbit. The Artemis II crew will be pioneers in many ways So that. Artemis II will not land on the lunar surface. That will be the goal of Artemis III. However, its 10-day trip will include a flyby to the Moon, in which key systems, such as life support, navigation and communications, will be tested. Photographs will also be taken of the hidden side of the Moon, in order to analyze its geology. and other data of scientific interest. Meanwhile, astronauts will carry sensors that will help verify the alterations that their biological parameters experience in space. The countdown. While it is true that the true countdown lasts 10 minutes, during the 50 hours prior to launch There is a very well established testing and preparation schedule. It all starts with preparing the fuel loading systems and powering up the ship. Other important key points are, for example, the ignition of the batteries, which occurs 33 hours before or the cooling and subsequent filling of the various fuel charging and propulsion systems. These steps are taken starting 10 hours before launch. Also very important is the flight crew’s weather briefing, which takes place 6 hours before the rocket is launched. The real countdown. During the last 10 minutes, very sensitive tasks for the launch are carried out. Above all, in this countdown the last checks are made to all the systems and the refueling of the fuel tanks is carried out. This means that the tank is refilled to the optimal level to replace the fuel that has evaporated during the filling stages. In these last minutes, the final pressurization of the tanks is also carried out and the rocket goes into internal energy mode. That is, it stops using energy from the terrestrial electrical system and uses only its batteries. What can go wrong. Any minor detail that does not work properly during the 50 hours before launch could cause the mission to be postponed. The most sensitive points are, without a doubt, those that have to do with fuel. For example, many missions have been canceled when leaks were detected in the tanks that could not be solved at the time. Adverse weather could also force the launch to be delayed. When. A launch cannot take place at any time. The Earth revolves around the Sun and the Moon orbits the Earth. In order for a rocket launched from Earth to follow a suitable trajectory towards the Moon, it is important that it be in a suitable orientation, taking into account their respective orbits. These specific moments are known as launch windows. Artemis II will have one of these windows today for two hours. If the launch could not be carried out due to any error, this month there will be several more opportunities, on April 2, 3, 6 and 30. After takeoff. The first 8 minutes after takeoff are critical. The engines are working at maximum power to leave the Earth’s atmosphere and arrive, now, slowly. Above all there will be two critical ignitions in the rocket’s upper stage, known as ICPS. The first serves to stabilize the orbit and the second to take the rocket to high Earth orbit. It is important that these go well so that the mission can move forward. Once those critical 8 minutes have been passed, the mission will have a lot of flight ahead of it, but at least the most complicated part will have passed. Even so, still We will have 10 days to closely follow the work of these 4 astronauts which, of course, have already gone down in history.

AEMET points this year to the opposite

by

We are already in Holy Week and the question that is asked a lot during all holy days is the same: is it going to rain? And it is no wonder, because practically every year during Holy Week there is some day that is quite bad and forces the much-loved processions to be suspended, causing sad scenes of people crying for not seeing the image to which they have devotion or for not being able to show off the work of an entire year. An exceptional year. But this year This does not seem to be the case, since, after the logical doubts of the previous weeks, the AEMET has confirmed that climatological stability will be the norm this Holy Week. The sun as the norm. The dominant note of this Holy Week will be thermal recovery, causing the cold fronts to be left behind and maximum temperatures to experience again. a general rise in most of the country, leaving us with a fully spring atmosphere. In the case of the regions of Andalusia and the Levant, they will be in luck as they will benefit most from this rise, causing the thermometers to be at a very pleasant 20-25 ºC. In the case of the center and north of the peninsula, they will also see mild weather, moving in a range of between 15 and 20 ºC. There is small print. Just because we are talking about general stability does not mean that the entire country will have clear skies. As is usual when Atlantic anticyclones dominate, the extreme north and some areas of the Mediterranean will bear the brunt, although without major storms in sight that are practically reduced to zero probability. In this way, the AEMET maintains active warnings in areas such as Empordà and the Balearic Islands due to strong winds from the north, which will alter the maritime situation. Something that has already resulted in the closure of the main port of Menorca. Some exception. Until Holy Thursday, the weather map will leave us with some weak rainfall on the Cantabrian coast, and there could also be scattered showers in the Balearic Islands and the southeast of the peninsula. Furthermore, the intense cold is relegated to the mountains, meaning that only weak frosts and some light snowfall are expected, but at altitudes above 1,500 meters, affecting the Pyrenees and the Iberian System. At the end of the week. Unfortunately, weather doesn’t mix well with long-term planning. This means that right now, for April 4 and 5, the predictive models point to possible instability that suggests some rain in the west and south of the peninsula, but nowhere near something widespread in a large area of ​​the region. But the a priori idea that we should have is that the sun will prevail in a good part of the peninsula, and will ensure that all devotees can enjoy a good Holy Week.

We are stuffing ourselves with supplements because of the networks. Science points out that we are almost always wasting money

by

A scene that can be quite common (or at least it has happened to me) is opening TikTok and, at some point, between cat videos and recipes that seem very simple, a person appears and explains why. Magnesium will change our lives. Sleeping poorly, having anxiety, muscle pain or even going constipated These are some of the claims that constantly bombard us so that we end up supplementing our diet with some of the products that are available (and that are not cheap). The problem is that it is getting out of hand. A great use. Get out of bed and, before drinking your first coffee, there is already a row of pills that you have to take to start the day: vitamin D, creatinethe ashwagandhamagnesium… A real ‘skincare‘but for the metabolism, which is becoming more and more aggressive. According to 2024 datain the United States 61.72% of adults take some type of dietary supplementation, and the figure has been growing for years. But the worst of all is that, of this high percentage, almost half of the people take it independently, without following the advice of a doctor who has been able to detect the deficiency of a specific vitamin. The problem of networks. A systematic review of 82 studies published in Healthcare in 2025 analyzed the impact of social networks in health behaviors between the years 2010 and 2025. Here he was able to identify health misinformation as one of the five categories that dominated the digital content ecosystem, since these platforms function as tools that dictate what to do to be healthy, even if there is no evidence behind it. What encourages all this is nothing more than a business model that is seeing as its income they don’t stop increasing. And logically here it is not interesting to point out that the vast majority of people can receive these ‘miraculous’ minerals thanks to a varied diet. And everything that is taken in excess can end up being excreted very well. What does science say? In 2022, a study focused on vitamin supplements and minerals to prevent the appearance of cardiovascular diseases or even cancer, the truth is that it was very revealing. The conclusion here was that for beta-carotene, vitamin E supplements or multivitamins there was not enough evidence to say that they were positive for health. But they weren’t very harmful either. If we go further, a published meta-analysis in it Journal of the American College of Cardiology In 2022, it reviewed 884 randomized clinical trials with 883,627 participants on 27 types of micronutrients. The picture is nuanced but clear in general terms: vitamin C, vitamin D, vitamin E and selenium showed no effect on cardiovascular disease. Beta-carotene, again, increased overall mortality, cardiovascular mortality, and stroke risk. But there are exceptions with omega-3 that did reduce the risk of heart attack and cardiovascular mortality. Magnesium. Without a doubt, the revolution of the moment, since it seems to be used for absolutely everything. In 2020 it already appeared a review on magnesium oral to see if it actually reduced muscle cramps, and the truth is that the conclusion was that it was unlikely to provide clinically significant relief to older adults with night cramps. This does not mean that magnesium is useless in all contexts. It means that if you are a healthy adult who takes magnesium because “a TikTok influencer recommended it to you for cramps” you are wasting your money. But if it is taken because an analysis has confirmed that magnesium levels are below normal, it can be very useful. Vitamin D. A few years ago this was the fashionable supplement for everyone, since it was sold that there was a general deficit among the population. In this case, the experts pointed out that vitamin D should not be supplemented on a general basis in healthy adults under 75 years of age to reduce the risk of disease. There is evidence in favor of supplementation in specific groups such as children and adolescents to prevent diseases such as rickets, people over 75 years of age to reduce mortality, and pregnant women to reduce the risk of preeclampsia and premature birth. In this way, supplementation is useful, but always with medical advice behind it that sees it justified to send a vitamin supplement. When to take them? The honest answer is: in specific and well-defined contexts, with clear clinical indication and as preventive life insurance to avoid all diseases. In some cases it is clear that it must be done, such as folic acid in pregnancies, vitamin B12 in vegan diets or vitamin D in groups with documented deficiencies. But what doesn’t make sense is taking a daily cocktail of eight supplements because we have been sold that it is necessary for our body to ‘start’. But it also has the logic of why we take it, since we have a constant feeling that we need to be more rested, focused and healthier. Here supplements offer us this very easy solution: with a pill. The problem is that our body works with constant balances and no matter how much we throw at it, it will not respond as we can expect.

NASA chose 34 points around the world to track its lunar mission and only one in Spain. It is in Seville, on a rooftop

by

If the weather behaves well and no problemsnext April 1 (early morning on April 2 in Spain) NASA will launch Artemis II. It will be the first manned mission of the Artemis programand in it four astronauts will travel aboard the Orion capsule to orbit around the Moon. during the mission 34 locations spread around the world will track the spacecraft’s radio signals and send their data to NASA. One of these headquarters will be in a special location: the roof of the Higher Technical School of Engineering of the University of Seville. A NASA antenna in Seville. In August 2025, NASA published an open call for third-party organizations to demonstrate their tracking capabilities during an actual manned mission. All types of organizations, agencies and institutions showed up, and even private radio amateurs also did so. Of the 34 selected around the world, the ETSi is the only Spanish center that will participate in this monitoring. The Orbisat system in operation. Source: Integrasys. space roof. It will do so in collaboration with Integrasys, a Spanish company specialized in this field and which has installed its platform on the roof of the ETSi building. Orbisat. This 2.5 meter high system has been developed at its Luxembourg subsidiary and is designed to track space vehicles both during launch and during subsequent operations. Plan B. The ETSi and the Orbisat system will receive the radio signals that the Orion spacecraft emits during its trip, process them and send them in real time to NASA for analysis. The key data they will measure is the Doppler effect of the signal: the variation in frequency of the waves depending on the relative speed between the ship and the antenna. It is a key parameter to determine both the position of the ship and to calculate its trajectory. It should be noted here that this system will not be responsible for the main monitoring, which will be done from the network Deep Space Network from NASA. This monitoring will be complementary and will help the agency evaluate what monitoring capabilities it can use outside of its own infrastructure. It’s a plan B. Why 34 antennas?. This support program responds to a very clear strategy of the space agency: build a public-private space tracking ecosystem that does not depend on its own network. Kevin Coggins, deputy director of the NASA SCaN programhe explained in the official announcement that “it is not about tracking a mission, but rather about building a resilient ecosystem that supports future exploration.” The initiative is an evolution of what was already done in 2022 with Artemis I, when ten volunteers tracked the unmanned mission. On that occasion, data format and quality problems were detected, and for Artemis II, participants have been forced to meet certain standards. An opportunity for Seville and for Integrasys. The Orbisat platform will be installed in Seville permanently, which turns the ETSi into a real monitoring infrastructure and not a one-off collaboration. For the company Integrasys, based in Las Rozas (Madrid), this first direct collaboration with NASA adds to those it already had with the Space Force and the US Space Command. Now it remains to be seen if this serves as a gateway to its participation also in future space missions such as Artemis III, which will land on the lunar surface. The Aerospace Technology Group of the University of Vigo will also participate in monitoring the mission. The students are in luck. The Master in Space Systems Operation at the University of Seville is taught for the first time in this 2025-26 academic year. Students will have direct access to the data generated by Orbisat during the Artemis II missionand with them they will be able to apply orbital determination and trajectory analysis techniques in that real scenario. For them this occasion is special, since they will be able to go beyond the books and have access to the telemetry of a manned spacecraft orbiting the Moon. A much more powerful way to learn, without a doubt. Spain on space map. The network of the 34 selected includes organizations such as the Canadian Space Agency, the German DLR, companies such as Telespazio and universities from Switzerland, Japan and the United States. Seville is on that list along with individual radio amateurs from California or South Dakota, amateur radio organizations such as AMSAT in Argentina or Germany, research centers in Cameroon or New Zealand and professional stations in Norway and the United Kingdom. The conclusion is clear: NASA has here the beginning of what can be a heterogeneous and decentralized network with monitoring capabilities. The Spanish participation on the Artemis II mission, by the way, goes a little furtherbut could go much further even. Image | NASA | ETSi In Xataka | In 2018, Elon Musk put his own car into orbit.

The US has sent Iran 15 points to end the war. He has also sent a plan B as explosive as it is disconcerting through the air

by

In the Cold War, the United States and the Soviet Union held open negotiations while, at the same time, deploying thousands of troops and nuclear weapons in key points of the planet. In reality, that logic of talking and putting pressure at the same time has never disappeared and continues to be one of the most recognizable constants of modern conflicts. The 15 points. First the official route. The United States has sent Iran a 15 point plan to try to end the war, using Pakistan as an intermediary and with the intention of stopping a conflict that already affects energy markets and regional stability. The document addresses key issues like the nuclear programballistic missiles and maritime security in the Strait of Hormuz. However, it is not clear whether Iran has even agreed to discuss it or whether Israel endorses the content. Furthermore, much of the plan appears to be based in previous proposals which have already been rejected, which casts serious doubt on their real viability. Diplomacy does not stop war. Although Washington presents the plan as a way out, the reality on the ground is very different. military operations have continued without pause within that campaign named after a Michael Bay movie, Epic Fury. In fact, the United States and Israel have continued attacking infrastructure Iranian military while Iran maintains the launch of missiles and pressure on maritime traffic. The White House itself has made it clear that the negotiations they do not replace to military objectives. In other words, the situation generates a scenario in which diplomacy advances in parallel with an escalation that does not stop. F 35c The ground deployment. At the same time that there is talk of agreements, the United States continues sending and increasing its military presence in the region. There are already nearly 7,000 new troops sent in a few days, including units of the 82nd Airborne Division and marines prepared for rapid operations. So that? In theory, these forces can act in specific scenarios such as the capture of strategic points or the reopening of maritime routes in Hormuz. There is no doubt, its deployment does not respond to a withdrawal, but to the expansion of military options available if the negotiation fails. Advanced capabilities by air. The reinforcement is not limited to ground troops. New fighter planes have also appeared like the F-35Cunits that are being deployed to the area of ​​operations, adding to an already very large air force. These systems provide precision strike, close support and air superiority capabilities. Not only that. Movements of other assets such as airplanes have also been detected special operations and deception systems against anti-aircraft defenses. In short, everything points to preparation for more complex scenarios that a simple containment. If the 15-point plan does not work, plan B is ready to act. The strange B2s of plan B. In this context, the B-2 bomberswhich are operating from US territory and have appeared with some visible modifications on its wings that have not been explained by military sources. They counted the TWZ analysts that these changes could be related to sensors, electronic warfare or improvements in its survivability, but there is no official confirmation. Your role, as almost alwaysseems key for Washington because they are the only ones capable of attacking highly protected targets long distance. Its presence, along with these modifications, reinforces the idea that the United States is preparing specific capabilities for more demanding phases of the conflict. A plan that does not resemble a negotiation. The combination of all these movements paints a fairly clear scenario. While presenting a peace proposal publicly, a military architecture is deployed at the same time increasingly widerwith units like those B2 with additions that had rarely been seen in other conflicts. A troop contingentfighters, strategic bombers and naval reinforcements accumulating in the region, suggesting that Washington is not betting solely on a negotiated solution. Rather, an alternative is being prepared in which military pressure increases if talks do not progress. A disconcerting war. In recent months we have seen scenes of soldiers controlling machine guns mounted on drones with devices like a Steam Deckremote operations that seemed to mark the definitive course of modern warfare. It has been spoken artificial intelligenceof drone swarms and remote combat as the new standard. However, in parallel, the United States is preparing to send thousands of paratroopers (around 3,000), a capability designed in the 20th century to take key positions quickly. The image is difficult to fit because of its anachronism. While one part of the conflict aims at total automation, another recovers classic forms of massive troop deployment. This coexistence is not an anomaly, it is the sign that the current war does not replace what came before, or not at all, but rather accumulates it. Two open roads. The result of all this is a strategy that advances in parallel. On the one hand, an attempt to reach an agreement with multiple conditions extremely difficult for Iran to accept. On the other hand, a deployment which allows the war to be rapidly escalated if necessary. The key at this time and in the coming days will be whether one of these paths prevails over the other. Because, for now, the United States has sent two diametrically different messages at the same time, and both they are still active.

We have been adoring bananas all our lives for their potassium. Science points to raisins as the true “super snack”

by

In recent years it is easy to see on social networks like TikTok or Instagram different ‘specialists’ in sports or nutrition bombarding with different food supplementswith the best ‘super foods’ for good nutrition and more. However, in a corner of the pantries we may have a food that we despise, but that can give us many benefits in our daily diet: raisins. A great ally. A product that may be hated by many people because of its texture, but has been introduced by different nutrition experts as a very interesting option. The reason lies in the dehydration process, since raisins surpass very popular fresh fruits such as strawberries or bananas in nutritional density. The why. When we remove the water from a grape, what is left is a bomb of bioactive nutrients. This is what verified databases like the USDA and FatSecret point to, since a standard serving of 40 grams of raisins provides about 120-129 calories, between 1 and 2 grams of fiber and around 300 mg of potassium. And this is where the odious comparison comes in with the historical king of potassium and the one almost baptized as the treatment for soreness after sports: the banana. On paper, a medium banana has around 350-425 mg of potassium, while raisins, being dehydrated, They can reach 860 mg of potassium per 100 grams. In this way, we are talking about a brutal concentration of minerals that are key for the nervous and muscular system. What does science say? Far from being a simple grandmother’s remedy, the impact of raisins on our health is widely documented in different articles. One of these is an analysis published in 2017 which brought together almost 22,500 adults and revealed large numbers. Specifically, regular raisin consumers had 34% more fiber in their diet, 16% more potassium and on top of that they consumed 17% less added sugars. The results here were a 39% reduction in the rate of obesity and a 54% lower risk of metabolic syndrome. Effect on pressure. Beyond being a food that can be very attractive to gym lovers with the aim of alleviating soreness and also reducing sugar consumption, it can be ideal for our blood pressure. Here science has been able to see that the phenols and polyphenols of raisins have a powerful antioxidant effect, and that is why in patients with diabetes and hypertension, consume three servings a day manages to reduce blood pressure between 5 and 8 mmHg. But it doesn’t stop there, since it can also lower glucose levels after eating something and reduce very important inflammatory markers. At the digestive level, a 14-day trial showed that the fiber in this food acts as a powerful prebiotic, promoting the growth of butyrate-producing bacteria in our intestinal microbiota, which are known for their anti-inflammatory effect. Perfect fuel. Right now in the sports world there are a large number of products that promise to be a great pre-workout with artificial energy gels. In this case they have a moderate glycemic index, which translates into having sustained energy during training without the dreaded “bird”. But science pointed out, after analyzing triathletes, that taking raisins before exercising prevents DNA damage much more effectively than consuming equivalent amounts of pure glucose. Although beyond muscle there are other benefits, such as improvements in spatial memorywhich justify the famous Spanish saying: “For memory, corners of raisins”. Something that also seems like it belongs to older people, but that science has proven. It still has sugar. Clearly, raisins have many benefits, but it doesn’t mean you have to have a free bar of this food. And it should not be considered that way because in its composition it has natural sugars in the order of 24 to 28 grams per 40 gram serving. Although it does not behave in the body the same as white coffee sugar, since thanks to its matrix of fiber and phytochemicals, excessive consumption can cause glycemic spikes. That is why the recommendation that can be made is clear: moderation is the key.

The head of AI at Alibaba leaves the company. That points to a 180º turn for the Qwen family models

by

An employee leaving a company does not have to mean a radical change, especially when that employee has been the leader of an important project and his departure occurs just after the launch. This is what just happened with Junyang (Justin) Lin, the technological leader of the team qwen. A strange exit. On March 2, Alibaba launched a new model family lightweight with two fast models designed for edge use, a multimodal model for agentic systems and a reasoning model that stood up to much larger models. The next day, Junyang Lin announced on his X account “I am leaving. Goodbye, my dear Qwen,” without giving further details. And he wasn’t the only one. Also leaving the company were Hui Binyuan, a scientific researcher, and Yu Bowen, head of post-training at Qwen. No one has commented on the reasons behind his departure from the company and rumors that they had been fired They didn’t wait. However, according to Panda Daily, Alibaba said it had approved his resignation. ¿What is happening? Justin’s departure caused a stir among his colleagues, with some claiming that it was “the end of an era”. We are talking about the person who has led the Qwen team from the beginning and a great AI researcher, with an academic profile that exceeds 40,000 citationsso this decision has raised many eyebrows. Whether fired or resigned, Justin was a key figure on the team, but he also leaves just after a launch and several other employees have followed him. What is happening at Alibaba? Closed models. As we said, the parties involved have not offered more details, but the theories have not been long in coming and one of them is that Alibaba could be thinking of moving towards closed models. Alibaba has been making efforts to monetize its AI and closing their models could be part of the plan. It would certainly make sense for the project leader to quit at the prospect of such a profound change. There’s a new guy in the office. Shortly after the news broke, another one jumped out: Alibaba has signed Zhou Haowho until now was a researcher at Google DeepMind. Zhou will join the Qwen team as head of post-training, so he will directly replace Yu Bowen and not Justin. Zhou has been a key figure in the development of Gemini 3, the Seeker’s AI mode, and Deep Research mode. lto open source strategy. DeepSeek, Kimi, Qwen… Chinese companies have become the standard bearers of open source AI, an antagonistic strategy with the closed stance of the US. But it is not a question of giving away AI just for the sake of it, but rather it is part of their roadmap: offering access to create a large user base and thus be able to be dominant in the future. Furthermore, Chinese companies know very well that the US is technologically ahead (Justin himself recognized it recently), so launching open and free AIs is a way to gain ground on them. However, in the long term it does not seem like a very good strategy because there will come a point where they want to monetize it and there is a risk of losing users who feel betrayed. We do not know if Alibaba has already started down this path, but if it has, we will soon see if this risk is real or not.

We have been obsessed with doing more hours of sports for years. Science points out that we were wrong

by

For decades, the main message that medicine has conveyed to us is that physical exercise should be a priority and it has been summarized with one word: move. Accumulating hours of activity per week has been the great objective that many have had; However, a new study has come to turn this around, to give great importance to the type of exercise and how varied the training menu we follow is when we go to the gym. More and more complete. As we investigate more, the way we exercise is changing, and now a study published at the end of 2026 has suggested that combining different types of exercises reduces the risk of mortality, regardless of whether we do a lot or a little sport in total. That is why the message we must keep in mind is that, instead of doing many hours of a single exercise, it is worth diversifying a little between different modalities, dedicating a little time to each of them. How they have done it. To reach this conclusion, the research team used data from two large groups of people to bring together more than 100,000 people who were followed for more than thirty years. In this way, with different questionnaires, the team measured the active time that each of the people to be analyzed had, establishing a minimum threshold of 20 minutes of activity per week to estimate that someone was really doing it and that it was significant. The objective was to find a correlation between activity levels, the number of these activities and, above all, how they reached adulthood and even when they died in the event that they had not reached the end of the study. The results. The most striking finding is that the group of people who practiced a greater variety of exercise had 19% less total mortality compared to those who limited themselves to a single repetitive routine. But the most important thing is that this good effect of variety in activity is independent of the total volume of time invested in playing sports. That is, the mere fact that exercise is varied has a protective effect in itself, reducing the risk of dying from cardiovascular, respiratory, cancer and other pathologies by between 13% and 41%. The best sports. The study also broke down the individual impact of each discipline, showing a non-linear dose-response relationship, making the greatest benefits noticeable at the beginning, when we went from doing nothing to doing something. In this way, the best sports according to science are the following: Walking: 17% less risk. Racquet sports (such as tennis): 15% less risk. Rowing and calisthenics: 14% less risk. Weight lifting: 13% less risk. Jogging/Easy Running: 11% less risk. Cycling: 4% less risk. Its limitations. Logically, this note has important limitations, since the data were self-reported by the participants with questionnaires and the population analyzed was not too varied, being mostly white, so we must look to see if these percentages may vary by demographics. However, the consensus is clear, since just as nutritionists have been recommending for years that we eat a “rainbow” of different vegetables instead of gorging on just spinach, sports science is now asking us for an “omnivorous movement diet” in which we combine different types of exercise on a daily basis.
