Amazon Go and Amazon Fresh stores seemed like the future of commerce. Now they all close

Amazon has announced the definitive closure of its 57 Amazon Fresh stores and its 15 Amazon Go establishmentsending a decade of experiments to reinvent physical shopping. Fresh They were classic supermarkets, but with technological touches. Go They were stores without cashiers where you entered, took products and left: sensors and cameras charged you automatically. The only staff was the replacement staff. Why is it important. This is Amazon’s most visible failure in its attempt to move its e-commerce dominance to the physical world. A company that has made a success of selling everything online has not been able to sell basic products in physical stores while being profitable. The context. Go opened in 2018, Fresh in 2020. Both represented the futuristic vision of retail: cutting-edge technology, extreme automation and a clear obsession with eliminating friction. Amazon has admitted that it “has not created a distinctive customer experience with the right economic model.” An elegant way of saying that they have not found enough clients willing to pay the extra cost of all that innovation. Yes, but. Amazon is not abandoning the food sector. Now it’s going to convert some locations into Whole Foods, the chain he bought in 2017. Whole Foods has more than 550 stores, has grown 40% in sales and will open one hundred new stores. In addition, Amazon is also already delivering food at home in 5,000 cities in the United States. Between the lines. These closures say a lot about the impressive technology that these stores had: not even it can compensate for a mediocre proposal. Amazon Go eliminated queues, but perhaps that did not solve much if its real competitors did not have a problem there. Of course, “Just Walk Out” technology now operates in 360 third-party stores and more than 40 Amazon fulfillment centers. As is often the case, innovation survives where it makes economic sense. The failure of Go and Fresh was seen coming for a long time. The pattern. History repeats itself. Amazon has closed physical bookstores, stores pop-up and now also these concepts. Each closing tells the same story: mastering online does not make you a good offline seller. Especially if you aim for profitability. Bezos built his empire by eliminating intermediaries and friction at Amazon, but the physical supermarket has friction for a few reasons: people want to touch the fruit, compare products, decide on the fly… Human behavior cannot always be improved by algorithmic efficiency. Go deeper. The failure contrasts with that of other technological giants that in one way or another have managed to dominate the retail. Apple dominates its stores because it sells an experience, not just its products. And Tesla controls its points of sale because the electric car requires a certain evangelization. Amazon tried to apply its e-commerce formula (full automation, speed, elimination of staff) to a business that simply has other dynamics. A supermarket is not a logistics warehouse. And not even an entire Amazon, with all its resources, can impose its vision of the future if the customer does not buy it.

a 300 km “moving wall” to close sea routes instantly

In the constant pulse between China and TaiwanBeijing has been looking for ways to increase pressure without crossing the threshold of an open conflict. As maneuvers, exercises and actions in gray areas multiply, each new movement points to a key idea: control the environment. If a few days ago it was drone entrynow another formula has appeared. A wall that doesn’t shoot. He told it through images the new york times. China has shown that it can create a gigantic sea barrier without firing a single shot, simply gathering thousands of ships fishing vessels in formations so dense that they disrupt traffic and force other vessels to go around or through them with uncomfortable maneuvers. In one of the recent operations, around of 1,400 boats They suddenly abandoned their routines and concentrated on the East China Sea until they formed a rectangle of more than 300 kmwith a presence so compact that it was seen in the navigation data as a kind of continuous obstacle. The practical effect is obvious. If this is done near key trade routes, chaos pcan arrive very quickly without anyone having to declare a formal block. Maritime militia and war in gray. The relevant thing about the movement is not only how many ships appear, but what does it suggest about who It moves them and for what. Experts and analysts interpret these concentrations as a state-led exercise that dovetails with the use of maritime militia, a network of civilian vessels trained to support strategic objectives. Plus: it is a perfect tool to operate in that ambiguous zone where there is no clear attack, but there is a real pressure on the sea. It is a way of imposing control without showing frigates in the front row and without assuming the political cost of open military action, while the rest are forced to decide whether to treat that mass as civilians or as an organized force. Rehearsal of blocking… without calling it a blocking. In a crisis scenario over Taiwan, a mass like this no need to “enforce” a lock by force to be useful. It is enough to hinder, slow down and complicate the movement of commercial or military support ships. It can force route changes, introduce delays, create points of friction and increase the risk of incidents. It can also serve to mark areas where traffic becomes unsafe or impassable for hours or days. That kind of pressure fits ideas like “quarantine”which seeks to strangle the functioning of an area without completely crossing the threshold of open war. Saturation as a tactic. Another advantage of this “wall” is that it converts the sea into tactical noise. Thousands of small ships together can overwhelm surveillance and complicate the identification of real threats, especially if there are drones, radars and automated systems trying to classify contacts. In a tense situation, this saturation can also act as a screen. It can conceal movements, force the adversary to expend attention and resources, and open space for other operations. Although each ship is weak on its own, value comes when they multiply until they become a problem of management rather than combat. What is revealed. The Times analysts who have followed Chinese activity in disputed seas for years highlighted that it is not usual Seeing such a large and orderly formation, and maintaining relatively stable positions, does not resemble a normal fishing pattern. The important thing here is the organizational muscle. Gathering thousands of ships at a specific point, in a short time, and positioning them with discipline indicates a clear improvement in command, control, communications and planning. This suggests that China is practicing something that you can repeat when you need it, and that does not depend on improvisations or simple crowds. Why does it matter so much? The trainings were given in the east china seaclose to major routes that connect with Shanghai, one of the most important port centers in the world. It’s not just any place. They are maritime corridors through which goods pass daily, including Chinese exports and flows that connect entire economies. Controlling or interrupting these steps is a way strategic pressure first level, on Taiwan, on Japan and also on any actor that has to operate there, including the United States and its allies. Beijing’s official silence fits with the logic of these actions. There is no need to announce anything if what you want is to check capabilities, measure reactions and leave a clear message with facts. A difficult model to answer. The really surprising thing about this is that a fishing barrier It is a relatively cheap instrument compared to deploying large military unitsand it can also be scaled. If today there are 1,400 or 2,000 barges, tomorrow there could be many more in a time of crisis. And for the rival(s), the answer will always be uncomfortable. The main reason is that it is not easy to justify brute force against ships that present themselves as civilians, but it is also not feasible to ignore them if they are effectively blocking a critical path. That’s the value of this “weapon” that does not fire a single projectile. That of forcing a choice between tolerating the pressure or escalating first, while China gains time, control and the ability to shape the pace of the situation.

MG, Omoda and BYD close a spectacular 2025 and are among the best sellers

It was the last days of March 2023 when we traveled to the north of Madrid to attend the BYD launch. “Europe has had its eyes closed for a long time”they told us from the company. That felt like the arrival of the first Chinese brand to our country, the one that came to confront Tesla in the electric car. At that time, MG was already selling thousands of units in our country and there were minority alternatives but the arrival of a manufacturer that was approaching two million cars sold It was already more serious. Months later Chery would arrivewith Omoda and Jaecoo, but also Ebrounder the arm. Along the way, other minority brands such as Lynk&Co or Xpeng have also been bringing new models to the market. But the bulk of Chinese sales and impact in our country is concentrated in the three companies we have listed. MG is completely established in our country, BYD has completed its second full year (with a change of direction included) and Omoda, Jaecoo and Ebro have now established their offer. And the result has been very good for them. More models and more sales If the year of Chinese brands in Spain has been characterized by something, it is because have put more points of sale on the streetmore cars in those points of sale and, above all, more cars in the garages of your potential customers. At the end of 2025, in Spain the main Chinese brands have obtained the following results: MG: 45,163 units (growth of 46.78%) BYD: 25,556 units (growth of 373.87%) Omoda: 13,963 units (growth of 79.33%) Jaecoo: 9,728 units (growth of 785.17%) Ebro: 12,459 units (growth of 44396.43%, they only had one car available at the end of 2024) Are very striking data due to several factors: MG sold more cars in Spain than Citroën (34,286 units), with which it competes on price. And it sold more cars than classics like Ford (29,065 units), Nissan (34,711 units), Opel (26,549) or Skoda (42,387 units). BYD only sells plug-in hybrid and electric cars so its potential customer market is much smaller Omoda, Jaecoo and Ebro are three brands of the Chery Group but each of them competes with three or four cars that, in addition, can be stepped on in price but not in positioning. If the sales of the Chery Group are added, they exceed 35,000 units. Brand by brand If we focus on the approach of each of these companies, we must take into account that MG already has a wide range of vehicles but is managing to attract customers in one of the most complicated markets: that of the cheapest cars on the market. Almost half of the sales of the best positioned one are accumulated by the MG ZS, one of the most affordable options on the market that for just over 20,000 euros delivers the ECO sticker so sought after in a Spain with growing low-emission zones. This has been the first year with its hybrid version working at full capacity and that has been noticed. The same has happened with the MG3which accumulates more than 9,000 units and is its second best-selling car. He good result The MG ZS among hybrids can be seen on the list of best sellers. And, of the non-plug-in hybrids, the Chinese SUV is in seventh position, surpassed by a Peugeot 2008 that has accumulated just five more registrations and in a field where Toyota clearly dominates (three of the four best-selling cars in this segment are its). MG’s third big best-seller is a good example of where the strength of Chinese brands lies. The MG EHS is a plug-in hybrid that, again, conquers by price. It has managed to become the second best-selling plug-in hybrid of the year, surpassing a Toyota C-HR that could be the great favorite. But no one is offering as much size and equipment at a lower price among plug-ins than the Chinese brands. That’s why the BYD Seal U has been the best-selling plug-in hybrid. As we said in our testcosts the same as the Toyota C-HR powered by this technology but for a family it can be much more interesting. The BYD SUV is not the only Chinese one that sneaks into the plug-in hybrid. The Jaecoo 7 also has its market share, a model that has also focused on offering extensive equipment at a reasonable price, which has allowed it to position itself as the sixth best-selling vehicle of this type in our country. The appearance of all of them and the Omoda 9 and the Ebro S700 among the best sellers of December, it gives us a preview of 2026 where everything indicates that The plug-in hybrid is the other great asset of Chinese models for next year (after the entry range). In that low range, the Chery group has already begun to make room for itself with the Omoda 5 but hopes to hit the table with its hybrid version. The car not only has an ECO label, The SHS-H version is a hybrid with all the letters and a particular touch. Attractive price, a design that is being liked and extensive equipment are its great assets for next year. And if we look at BYD, the result can also be underlined as excellent. Surviving with electric cars exclusively was becoming difficult to grow quickly and they have put all their efforts into action. They tested the BYD Seal U DM-i and found that they have a gap among plug-in hybrids. Maybe your Signal 6 DM-ias a family sedan, has it more complicated but the BYD Atto 2 DM-i It is priced to be the most attractive option on the market right now. Despite everything, the company is the first of the mortals after Tesla. Elon Musk’s people continue to dominate the electric market in our country with an iron fist, where the autonomy/price ratio continues to outweigh the rest of the values. Of course, the … Read more

IKEA has had to close seven large stores in China. It is the symptom of a much more important trend

The real estate market was the great economic engine in China, but currently it is plunged into a deep crisis from which it does not seem that it will come out soon. Houses are not sold and, consequently, not as much furniture is sold either. If we add to this an increasingly strong online market and competitors with very aggressive prices, it is not surprising that IKEA is not doing very well. Seven fewer stores. IKEA China has announced which will close seven of its stores on February 2. These are seven large stores, known as ‘blue box’, located in Shanghai, Guangzhou, Tianjin, Nantong, Xuzhou, Ningbo and Zhejiang. After the closure, there will be 34 more operational stores in the country. Change of strategy. IKEA emphasizes that “we will move from large-scale expansion to focused development.” Its strategy is to move away from large stores and focus on local commerce. They plan to open ten small stores in the next two years, starting with the Dongguan store scheduled for next February. This strategy contrasts with the one they are following in other countries like the United Kingdom either USAwhere what they are closing are some small stores opened after the pandemic. Competence. As we said, the Chinese real estate crisis is one of the reasons why sales have fallen, but not the only one. The Swedish giant faces other difficulties, such as the emergence of new local competitors that offer Much lower prices and much faster deliveries. In this context, it makes sense that IKEA wants to focus on small stores and strengthen its online channel. In fact, recently They opened a store on JD.com. Online presence. In statements to South China Morning Posteconomist Fan Xinyu, attributes the closure to “a highly developed online sales market in China, a trend that has reduced the survival margin of physical points of sale.” It is estimated that in 2024 in China They delivered 5,400 packets per secondmaking it the largest online marketplace in the world. In this sense, we can say that in China it is more common to place an order online than to go to a large store such as IKEA. IKEA China. The Swedish company opened its doors in China in 1998 and went on to open 41 large stores. The company has not published financial data, but China continues to be among the ten markets where they sell the most. According to ReutersChina accounts for 3.5% of all IKEA global sales.

The European Space Agency has always launched rockets from South America. Norway is very close to changing that

The Arctic is no longer just that vast ice desert at the end of the world, but it has become a strategic point for many countries that they do not want to waste. And Europe does not want to let him escape, now opting to migrate the launch of part of your rockets from South America to this new location, something that has a great geopolitical strategy behind it. An agreement. The European Space Agency (ESA) and Norway recently signed an agreement to promote the creation of a new research center in the north of our planet: the ESA Arctic Space Center in Tromso. But it is not just another research center, but rather it is Europe’s response to ensure its autonomy in observation, navigation and communications in a region where it is already Russia and China is deploying its own infrastructure. The location. Choosing Tromsø as the city where to locate this new launch zone is not something chosen at random. If we go to a map, we can locate it far above the Arctic Circle, already being a city that has become a vibrant ecosystem of satellite data. Looking back, Tromsø already hosts mission control Arctic Weather Satellite, a satellite launched in 2024 that tried to demonstrate how a polar constellation can save lives through very accurate weather forecasts. But it also has a large number of institutions that make it a true Silicon Valley of the cold, housing the Secretariat of the Arctic Council and the Norwegian Polar Institute. A greater amount of data. The agreement signed between ESA and the Norwegian agency NOSA establishes a working group that will define the details before the end of 2026. This center is defined as an opportunity to monitor the melting of the Arctic, which warming four times faster than the global averagewhich gives us data on what will happen in the rest of the planet. It also entails an important national security reason, since today maritime traffic in the Northeast Passage does not stop increasing, and this means having signs of Galileo It allows you to have better control of everything that happens here. That is why, more than science, we are facing a critical center for civil security, search and rescue. The change of location. Until now, our gateway to space was French Guiana for a reason of basic physics: its proximity to the equator allows us to take advantage of the “impulse” of the Earth’s rotation to launch heavy satellites. However, the center of Tromsø and the new Nordic ports respond to a different need: polar orbit. That is why while from South America it is ideal to launch television satellites that remain “fixed” on the equator, the Arctic is the perfect balcony for satellites that must monitor melting ice or borders. Launching from the Pole, the satellite enters directly onto a North-South path that allows it to scan every corner of the planet as the Earth rotates below. In addition, being on the axis of rotation, rockets do not have to “fight” against the Earth’s lateral spin, which makes observation missions much more efficient and cheaper. Geopolitics. Beyond science, in this case there is a reading of territorial sovereigntysince while China invests in the “Polar Silk Road” and Russia increases its infrastructure in Siberia, Europe needs its own eyes in the north. In this way, while from South America it is ideal to launch television satellites that remain “fixed” on the equator, the Arctic is the perfect balcony for satellites that must monitor melting ice or borders. In this way, the Tromsø–Svalbard axis, added to the new spaceports of Andøya (Norway) and Kiruna (Sweden), consolidates northern Europe as the main gateway to space on the continent. This decision reduces dependence on external infrastructure as occurred in South America and obviously guarantees that all data remains in European territory. What’s next now. Norway, a member of ESA since 1987, brings its network of polar stations and its unique experience in polar orbit operations that are undoubtedly crucial in the current situation. From now on, the working group that has been formed has two years to design the governance and calendar of a center that promises to be “the control tower” of the European future in the Arctic.

close a factory in Germany

The history of Volkswagen goes a long way. So much so that Its origins must be sought in Nazi Germany when the State commissioned Ferdinand Porsche to create a Volkswagen. That is, a car for the people. It was 1934 but with all the state machinery working overtime, in 1938 the first stone of the Wolfsburg factory, taking as an example Ford factory in Dearborn, United States. Since then Volkswagen has not stopped growing. With its good moments and also his bad momentsthe truth is that the company has established itself as the second largest producer of cars in the world, only surpassed by Toyota and in a comfortable position compared to Hyundai-Kia, which remains in third position. In these ideas and comings, the company has maintained a recipe: the German industry is not touched. Until now. In the midst of the reconversion of the European automotive industry, Volkswagen seems to have crossed a red line. Why does an electric car have less autonomy than advertised? for the first time It was 2018 when in Xataka we went for the first time to the Volkswagen glass plant in Dresden. There, the company had been producing its Volkswagen Phaeton, a luxury sedan that It ended up being a million-dollar hole. and, above all, a resounding sales failure. The company had converted the space into a laboratory to produce the first e-Golfone of the first steps that the company took in the purely electric car market. Its productive volume was almost ridiculous If we compare it with any current plant: 72 cars a day. In 2022, we had the opportunity to return. The factory had changed completely. At least in his spirit. It was still producing electric Golfs… more or less. And that’s where their ID.3Volkswagen’s first big bet that had been born with the spirit of being its first best-seller and position itself as the new electric Golf. Production had already fallen by half, to about 35 cars a day. Now, Volkswagen has shelved the plant. The glass space is converted into a university center. The movement has much more to say in the symbolic field than in the practical one. The 230 workers have three options on the table: dismissal with negotiated compensation, retirement or transfer to another factory. But the closure of the German plant goes much further. For the first time, Volkswagen has to cease production at a plant in Germany. Its production, as we have seen, was very low and the center was intended more for development and innovation than for nourishing the German fleet. However, the move is important because it demonstrates the extent to which the company is struggling. Dresden wasn’t just a car plant, it was status. It was a declaration of intent, the confirmation open to the world that Volkswagen invested in cars that were not profitable in the short term but from which they could extract knowledge in the future. Thomas Schäfer, CEO of Volkswagen, has indicated that the closure of the factory “it was essential from an economic perspective”. A little over a year ago, Volkswagen already announced that it intended to cut its production in Germany, to the point that it assured that “all factories in Germany are in danger”. They were the first blows of a savings plan of 10,000 million euros three years ahead. The company had decided to bet heavily on the electric car but European demand It does not seem to have been enough until it grew very recently. In Europe, Tesla has swept with force until last year but, above all, customers They didn’t seem interested. in the most affordable Volkswagen electric cars like the ID.3. Not even in the most expensive ones, like the Audi e-tron which ended with the closure of a plant in Brussels. Porsche is already retracing its path of electric car investments. Volkswagen has encountered a perfect storm with three open fronts. In Europe, as we said, the customer is not buying the expected electric cars, which puts the amortization of investments at serious risk. In the United States, the tariffs applied by Donald Trump’s Government have caused losses of 1.5 billion dollars in the last quarter alone, it reported. The New York Times. And in China the client has turned his back to the European product. That has put too much pressure on cash flow, forcing Volkswagen to get rid of space that went far beyond a car plant by renting it out to the local university. The problem is that when financial difficulties force us to think about readjustments in the short term, what suffers are long-term investments (just what was being studied in Dresden), which implies less competitiveness in the future. A wheel from which it is only possible to escape if, once again, it is possible to sell what the public asks for, with sufficient profit margins to reinvest in the future. And so, believe in germanyimplies taking steps back in electrification.

The largest collection of malformations in Spain is in Madrid. And they are going to close it

Hidden in the bowels of the Complutense University of Madrid, half a thousand plastinated animals with congenital anomalies wait patiently for time, lack of funds and laziness to send them to a lost warehouse by the hand of God. More than 25 years of work that are about to be lost. A very very strange place. As Manuel Ansede told in El PaísNieves Martín and Luis Avedillo (two researchers from the Faculty of Veterinary Medicine at the UCM) have been collecting all types of animals with malformations for a quarter of a century. However, the lack of funds and the increasingly demanding requirements requested by the administration mean that the collection is on the verge of closing. The denial of the latest subsidies (of barely 23,000 euros) means that the situation is beginning to be unsustainable. And it is something very useful. Animal and human malformations are highly comparable, making the 500 specimens a very interesting resource for teratology, embryology and fetal medicine. We must not forget that, according to the WHO, Every year around 240,000 neonatal deaths are due to these types of problems and, despite all the progress we have made, we know too little. In fact, that denied grant of 23,000 sought to turn the collection into a reference center for these topics and develop a “malformopedia” that would complete the wonderful work that, for decades, the people of the Spanish Collaborative Study of Genetic Maformations coordinated by the Carlos III Health Institute. Is it really a problem? At the end of the day, without a stable and well-stocked repository, what we are losing is comparative material to study in depth embryological hypotheses and the mechanisms behind birth defects. We lose the ability to go further. Perhaps the best example is public health. By successfully integrating cases of congenital malformations (especially those in pigs) with human surveillance, we could accelerate the identification of signals about environmental or teratogenic exposures (and improve clinical guidelines). It is not an isolated event. And that’s the worst. The Olavide Museum (historical collection of ‘moulages’ – waxes – dermatological) or the long-awaited Cajal Museum (which never quite come true) are clear examples of the problems that Spanish scientific heritage has. While the Vrolik museum in Amsterdam or the Mütter of Philadelphia lead the international conversation in teratology, genetic research and the most recent ethical debates, Spain is unable to find 23,000 euros to adapt the facilities of its reference collection to current regulations. It is still a metaphor for the state of science in the country. Image | Philippe Wagneur

We have just discovered three Earth-like planets orbiting two very close suns

The iconic scene of Luke Skywalker watching the double sunset on the planet where he was raised, Tatooine, is one of the most indelible images in science fiction. Now, thanks to NASA TESS Space Telescopewe believe there are three planets similar to Tatooine within 72 light years of Earth. A unique system. It’s called TOI-2267 and it challenges what we thought we knew about how planets form. According to research published in Astronomy & Astrophysicsthis binary star system hosts three planets similar in size to Earth. But what makes it extraordinary is not that it can have two-sun sunsets, but rather its compact architecture. Two very close suns. TOI-2267 is formed by two M dwarf stars (M5V and M6V) that orbit very close to each other, at a distance of only 8 astronomical units. To put it in context, in our solar system, Saturn orbits 9.5 astronomical units from the Sun. Until now, theoretical models suggested that such a close binary environment was too chaotic and gravitationally unstable to allow planets to form and maintain stable orbits. TOI-2267 proves us wrong. How it works. The analysis of the system, in which the Institute of Astrophysics of Andalusia had an important participation, reveals that the three planets cannot be orbiting the same star, since the system would be unstable. The most plausible configuration, and the one that excites scientistsis that two of the planets orbit the main star (TOI-2267A), while the third candidate orbits the companion star (TOI-2267B). This makes TOI-2267 the first known binary system to host planets transiting both of its stars. The next step. After discovering the system with the TESS space telescope and carrying out follow-up observations with the SPECULOOS observatory, from Chile and Tenerife, and the TRAPPIST telescope, the next step will be to use more powerful instruments, such as the James Webb Space Telescope to try to measure the masses, densities and even analyze the possible atmospheres of these worlds. This system not only proves that Tatooine exists, but that the universe is capable of forming planets in the most extreme and unexpected places we can imagine.

We have been talking about microplastics for years without being very clear about how they affect us. Science is close to solving it

Plastic no longer only wraps our food or makes up the clothes we wear, but it has silently colonized our body. And microplastics have been found almost everywhere in the body: placenta, blood, lungs, testiclesbreast milk, brain human… But when faced with the big question of What effect does it have on the body?we are already having answers. The measurements. Studies already suggest that we could hold up to five grams of this material in our own brain. The image is shocking: the equivalent of a plastic teaspoon lodged in the deepest part of our being. Microplastics are particles, in this case they are very tiny, that come off from packaging, synthetic clothing, tires, cosmetics and countless everyday objects such as lettuce. But some are so small that they are able to cross the barriers of our lungs and intestines, travel through the bloodstream and deposit in our internal organs. What happens once there is the great unknown that scientists strive to clear up. The studies. Dr. Christian Pacher-Deutsch, from the University of Graz (Austria), recently presented a study in which he exposed human intestinal bacteria to five types of common microplastics. The result was quite clear: bacterial populations were altered, producing chemical changes, in some cases reflecting patterns observed in patients with depression and colorectal cancer. Although the researcher himself was cautious in pointing out that “although it is early to make definitive statements, reducing exposure to microplastics is a sensible precaution.” But the effects don’t stop in the intestine. Dr. Jaime Ross, a neuroscientist at the University of Rhode Island, conducted a revealing experiment: gave a group of mice water contaminated with microplastics to drink. Soon, the mice began behaving strangely, anxiously venturing into open spaces, an atypical behavior that is associated with aging and neurological diseases. Analyzing their brains, Ross found plastic in all organs and a reduction in GFAP, a key protein for brain health. This same pattern of exhaustion is seen in humans with depression and dementia. Caution. In this case, microplastics have been detected in arterial plaques, and an analysis concluded that people whose plaques were loaded with plastic were almost five times more likely to suffer a heart attack, stroke or die within three years. The practice. Faced with this avalanche of data, The Guardian wanted to move from theory to practice. The British journalist herself decided to undergo a test from the company Plastictox which, for £144, promises to reveal the amount of microplastics circulating in the blood. The test result indicated a concentration of forty microplastics per milliliters of blood. And although this figure placed her in the 25% of people with the least exposure, the laboratory gave her the total result: about 200,000 plastic particles in the bloodstream. However, other experts urge caution. Professor Stephanie Wright, a researcher at Imperial College London, calls this evidence “very premature.” He points out that although an analysis shows that there are 40 particles per ml, it is unknown if this is good or bad or if it will depend on the type of plastic it is or its origin. We live in real uncertainty. The advice. Although it is impossible to avoid exposure completely, there are a number of tips to avoid consuming this type of microplastics. For example, you can choose not to use plastic kitchen utensils or drink hot liquids from plastic cups. Even with the tap water either bottled we can have the same problem. Outside of food, the material composition of bedding or pajamas should also be reviewed, as they can release these types of particles, making cotton the best.
