problem

The US has decided to leave paper straws because everyone hates them. The problem is the alternative: plastic

by

Between him merchandising Maga with whom he dressed his bankrupt 2020 attempt For returning to the White House, Donald Trump included a much less resulting piece than his famous red caps, but endowed with the same political burden: plastic straws. The cannulas carried their last name in capital letters, were sold in packages of $ 15 and were, in the words of the Republican leader, the alternative to the “Liberal straws” of paper. They did not serve to win those elections, but to raise thousands of dollars. Now, back at the White House, He has decided that the whole government also begins to use plastic cannulas instead of biodegradables. And as happened in 2020, with it he launches a message that goes beyond the straws. What happened? Donald Trump doesn’t want more straws. Rather, he doesn’t want more paper straws. That’s why He has just signed An executive order with which he reverses the efforts of the administration of his predecessor, Joe Biden, who advanced right in the opposite direction. The Democrat aspired that federal institutions be disregarding plastic cannulas throughout The next few yearsfirst taking them out of their activities in 2027 and then suppressing them until they reduce them to zero in 2035. Why’s that? Simple. Because Trump doesn’t like them. He made it clear already during his failed electoral campaign of 2020 and has stressed again these days, in a resounding way and without half inks, faithful to his style. “These things do not work, I have had them many times, and sometimes they break, they explode. If something is hot, they do not last long, a matter of minutes, sometimes second. It is something ridiculous,” He settled. The republican argument does not end there. Trump has insisted that the attached straws that have been promoting as the ecological alternative to the traditional plastic are dissolved for years “disgustingly” in the mouth and even questions that its use is positive. For both consumers and the environment. Its decree in fact that they incorporate chemicals that “can entail risks to human health”, their production is more expensive than the conventional alternative and also generate waste. “Paper strases are sometimes involved individually in plastic, which undermines the environmental argument in favor of its use,” emphasize. Goodbye to biodegradable straws? Not quite. Trump’s decision is relevant and there are those who have seen in it A declaration of intentionssomething that goes far beyond the simple cannulas. The Executive Order declares that “US’s policy is to put an end to the use of paper straws”, but at the moment its scope is limited: it focuses on the federal administration, putting an end to The Biden era policy that sought that the federal government gradually eliminate the purchase of plastics from a single use. The regulatory framework around the straws is really something more complex. There are cities and states, including California, Oregon, New Jersey or Seattle, in Washington’s own territory, endowed with regulations that limit the use of plastic cannulas or prioritize biodegradable options. Trump’s goal is clear, in any case. Before journalists, he shared transparently what his bet is: “We will return to plastic straws.” Do paper straws work? Trump ensures that its use leads to “ridiculous” situations and even that they are “disgusting” in certain cases. Those are personal, subjective appreciations. What can be affirmed objectively is that science has demonstrated that biodegradable cannulas are far from being perfect and – beyond that they may or may not be softened while using some problems related to their materials. In 2023 a group of researchers published A study in which they exposed their conclusions after analyzing 39 brands of straws of different materials, from plastic or paper to glass, steel and bamboo. And his conclusion was that the biodegradable cardboard were the ones that contained the highest volume of PFAS. That is a problem because these synthetic substances are harmful to humans and the environment. Of a total of 20 paper cannulas brands, 18 showed PFAS. Why is it a problem? It He expressed clearly Two years ago at SMC Marieta Fernández, a professor at the University of Granada, precisely following that study. “The majority of paper analyzed (90%) contained pfas. They were also detected in 80% of bamboo, 75% of plastic and 40% of glass. The steel analyzed, “summarized the academic. Fernández recalls that PFAS are commonly used for non -stick purposes and to improve the resistance of water, heat or spots, so “it is not surprising” to find them in the cannulas. The problem, abundantis that their presence in paper and bamboo straws would question that they are really “biodegradable.” And what is so or even more serious: it question that they are really “suitable for human consumption” products. Better plastic? Paper strases may not be perfect, but those of plastic are also very far from being, no matter how much Trump likes them, confessed lover of sugary and gas sodas. As Remember Fernándezthe study of 2023 also detected PFAS in the plastic units. And while its percentage was lower than in cardboard versions, the result remained elevated: chemicals were detected in 75% of the samples. His big problem is nevertheless another: the impact they have on the environment. The data does not always coincide, but they usually show a worrying scenario. There are estimates that speak that in the US they are used a day 175 million of disposable straws, Straws Turtle Island Restoraction Newtory raises the data to More than 390 million And another calculation –so cited as disputed– points out that in the country each day more than 500 million of cannulas. And what does that mean? Let any of those figures or Another estimatethe truth is that we talk about a quantity of huge straws: hundreds of thousands daily, in the best case, which take only a few minutes to become garbage. The big question is … What to do with them when they are discarded? Do they all end up in the … Read more

The biggest problem of Perovskita’s solar panels was its durability. China has just resolved it

by

The University of Beijing has just presented the most forceful advance of Perovskita cells in terms of durability, so far the greatest weak point of technology that promises to conquer solar panels. The news. A team of researchers has designed a Perovskita cell with a 24%efficiency, similar to that of the best silicon solar panels, than maintains 99% of its performance after 1,100 hours of operation at extreme temperatures. The context. Perovskita cells are The most promising technology to generate solar energy at low cost. Perovskitas have a crystalline structure that absorbs sunlight in a very efficient waybut unlike silicon cells, they can be manufactured through simple processes, with cheaper materials, and in flexible films. There are already commercial solar panels of Perovskita and have begun to be installed on a large scale, especially in complicated lands of Chinabut their least stability and durability prevents them from competing with silicon in other facilities, even when they are manufactured in tandem with the semiconductor to improve their performance. The problem. One of the key components of Perovskita cells, the formamidinium and lead iodide (FAPBI₃), is difficult to stabilize at room temperature and tend to degrade when it is exposed to sunlight for long periods. Which, for a solar panel, is … inopportune. FAPBI₃ degradation causes Perovskita solar cells to lose efficiency rapidly (they convert less amount of light into electricity) and are not viable to compete with silicon panels, which last 30 years. The solution. To overcome this obstacle, a laboratory from the University of Beijing has invented A new “intercalation-decalation” technique of iodinewhich consists of inserting iodine atoms into the structure of the FAPBI₃ to help better organize its components, and then eliminate the excess iodine during the heating process. The key is to facilitate the formation of lead and iodine blocks, whose atoms are joined by sharing corners in the structure of Perovskita. By favoring this configuration, the mobility of the ions is reduced that, otherwise, would contribute to the degradation of the material over time. Iodine acts as a stabilizer that improves the internal cohesion of the cell. The results. This method allowed researchers to obtain a high quality Perovskita movie, without waste that may compromise their performance. The cells that developed have an energy conversion efficiency of 24%: almost a quarter of the solar energy that affects them is transformed into electricity. But the most important thing is that they maintained 99% of their initial performance after operating for more than 1,100 hours at about 85 ° C, which is a very encouraging indicative of its durability and potential long -term use. As for lead. Lead concerns its toxicity, but today it is an essential component in the Perovskita formula: it contributes significantly to its ability to absorb light and turn it into electricity, so that commercially viable cells contain lead. However, solutions are also being investigated To eliminate it. Goodbye to defects. In addition to the one at hand, other laboratories are explored complementary solutions to eliminate defects, such as the integration of molybdenum disulfide layers (MOS₂) In the structure of the cells, which act as physical and chemical barriers, blocking the migration of those defective ions that can deteriorate performance. Both the technique of iodine and that of the MOS₂ point to the same: achieve a pure and stable perovskita that can work optimally and lasting. And convert the “great promise” of solar panels into a commercial reality. Image | Huansun In Xataka | In 2009, Perovskita’s solar panels wasted 97% of energy.

His biggest problem has not been money, but balance

by

Passing a vacation aboard a cruise is a tourist option increasingly demanded even for travelers high purchasing power. However, Mario Salcedo, a millionaire who made a fortune in finance, decided 25 years ago to turn his day to day on a vacation. Since then, he has been linking cruise trips making these colossi of the sea In your home. However, that life of luxuries aboard some of the biggest recreation ships has taken its toll: it has lost “its earth legs” and is no longer able to walk in a straight line when it arrives in the port. Live on vacation. The Millionaire of Cuban origin told In 2019 a The New York Times that he was never interested in forming a family, so his life on the mainland was only to work and work. So one day he decided to leave his apartment behind in Miami and cruise. The experience impacted him so much that since then he has been linking one cruise with another and now his house has several covers, swimming pools, dance tracks and some fleeting neighbors with which he socializes whenever he can. After being a regular between the passage of the Royal Caribbean companythe crew already knows him as Super Mario. “I have no vacation. People come here to spend a vacation. I don’t, I’m here to live my life,” explains the millionaire. Life on board. The Millionaire Investor uses a reserved table on one of the covers of the cruise in which it can be read on a handwritten sign “Super Mario’s office”. Obviously They do not refer to the Nintendo characterif not to the place from which the millionaire sits every day for a few hours before his laptop to telework. In this way, the more than 1,154 cruises that he has completed in his life on the high seas has been paid. The Millionaire claims to dedicate between $ 70,000 and $ 100,000 a year for their trips. The millionaire counted in An interview For Condé Nast magazine, who reserved an inner cabin without a balcony, because “I do nothing in my cabin but shower, dress and sleep,” he explained. The rest of the day could be found in his “office”, socializing with other travelers or dancing in one of the ship’s dance rooms. To avoid having to constantly changing cabin, Salcedo plans it with 150 reservations in advance, linking a journey with another. The worst of living in a cruise is to get to port. Everything would indicate that the greatest cost of living in a cruise is money. However, for “Super Mario” the greatest sacrifice is to go down to the ground. After more than 25 years rocked by the swing of the waves in the best cruises, the millionaire has developed a rare disease called Landing disease. This is a rare disorder that affects the vestibular system of the ear that affects the balance giving a constant sensation of movement even when it is stable and motionless on the mainland. It is popularly known as “earth legs.” Usually, this is a disorder that remains as much for a couple of days, but when your life transcurns on the high seas, and you only pass a total of fifteen days a year on land, the disease becomes chronic. “I have lost my land legs. I swing so much that I cannot walk in a straight line. I am so used to being in ships that I feel more comfortable than on land,” I said in his interview. It does not usually go down to land. It is unquestionable that Mario Salcedo is found aboard a cruise as a fish in the water, so, the few times that he goes down to the ground to take a plane that takes him to his next cruise, when they dock in Miami to verify that Everything is still in order in your apartment or when you have to make efforts with the bank or medical visits. Luckily, except for his problem with balance when Pisa Tierra Firme, the Millionaire Sexagenarian enjoys good health. A key factor for “Super Mario” to follow your adventure on the high seas, given that shipping companies prohibit That a person who needs constant medical care rises on board.

We have a problem with pesticides in agriculture. And a bigger one with the panic they generate

by

Fear is a powerful weapon, and also a double -edged sword. Fear can lead us to caution or paralysis and dividing line is not necessarily wide. In the food sector this is especially true: Food is a pillar of our healthbut there are hardly any foods or additives that have not been at one time or another affected by some form of collective fear. A classic protagonist in this context is the pesticides. “People prefer not to know what the lettuce, tomato or strawberry by the BBC. Navarro de Castro is a sociologist and diploma in rural extension and development and in its latest novel, greenhouse planet, addresses The issue of the agricultural system That feeds us. Contemporary agriculture is difficult to understand without use of pesticidesnatural or artificial chemical compounds destined to poison arthropods and other animals that could threaten plantations. These compounds allow the integrity of our crops not to depend on periodic pests or that every year we lose a fraction of our production consumed by these animals. Pesticides raise two big problems. The first, about human health: if these compounds end up in our food chain, they can mean a risk to our health. The second risk is environmental: these compounds can end up extending beyond our orchards and greenhouses, causing damage to the environment. The possibility of consuming toxic substances in our foods scares. It is normal. But would you really be justified to eliminate entire categories of our diet for the fear of pesticides? Perhaps before reaching conclusions it is important to have a notion of the magnitude of the problem. A magnitude that can vary depending on our location: each country has its own legislation when regulating the use of pesticides, but also the ability to assert those laws It can depend on our geographical context. In Europe, the European Environmental Agency (EEA) published in 2023 A report in which analyzed the impact of pesticides in the environment and in our health. They observed, for example, “above the barrier of worrying” in 22% of the points monitored in rivers and lakes of the continent. They also referenced a study published in 2019 in which pesticide residues were found in 83% of agrarian soils in Europe. But the pesticide track is not only still in the environment, but also in our own bodies. In this case, the EEA refers to a study that monitored participants in five European countries between 2014 and 2021. In result: they found indications of the presence of at least Two types of pesticide in 84% of the sample. As the agency explains, the levels detected used to be older in children with respect to adults. The good news, in a certain sense at least, is that the sales of pesticides in the old continent were stable. Threat to health And what consequences can pesticides have on our health? It all depends on pesticide and dose so to talk about impacts. As noted The World Health Organization (WHO), pesticides are “potentially toxic for humans and can have both acute and chronic effects on health depending on the quantity and way in which a person is exposed.” The people most exposed to these agents are not necessarily consumers, but people with more risk are Those who manipulate themeither in their work as in their homes and orchards, adds the UN agency. The EEA indicates Some of the potential effects on our health. These include cancers such as non-hodgkin lymphoma, ovaries and prostate; neurological problems such as Parkinson and Alzheimer’s diseases; cardiovascular diseases; problems in the development of the little ones; reproductive problems both in men and women; and cognitive problems. Inter alia. The agency also points out that today it is impossible to estimate the degree to which these problems affect the European population. The issue of health impacts on health Still still investigated For experts from all over the world. The obvious question is, is there a solution? Washing the fruits and vegetables that we are going to consume is a simple act that Help reduce our exposure To this type of agents. But They do not solve the problem: This action does not eliminate all pesticides, does not avoid other forms of exposure and fails to reduce its presence in the environment. In Your interview with the BBCNavarro de Castro proposed a simple solution and within reach of consumers. “From the collective point of view, a thousand simple things could be done such as eating seasonal,” acquiring awareness of the origin of each product that we lead to our homes (and our stomachs).

We have a problem with heat in buildings. A Navarra investigation knows how to cool them without air conditioning

by

Every year we repeat the phrase that this has been the year less hot in the coming yearssince it is one of the consequences of climate change. One of the “traditional” ways that we have to refresh in our homes is with an air conditioning system, but poses an economic problem, because the invoices are not paid alone. However, a new Navarro study has managed to find a solution to refrigerate buildings with hardly any energy expenditure. Short. A research team, Formed by Amaia Zuazua Ros from the University of Navarra and Cristina Salazar Castro of the Luredera Technology Center, has developed a project to cool buildings without the need for air conditioning. Under the financing of the Government of Navarra and within the framework of the Navarro R&D System (SINAI)and with the coordination of Aditechthe proposal has sought to boost new passive cooling technologies through modules coated with nanomaterials, designed to eliminate heat from buildings without resorting to electrical systems. The challenge is not less. In the last 30 years, the energy consumption for the cooling of a home is It has tripled. These data, detailed in the International Energy Agency, have highlighted the impact on global electrical demand. For this reason, reducing this consumption without compromising thermal comfort is one of the great challenges of energy efficiency today. The operation. The system is much simpler than it seems. To explain it more easily, the researchers have identified a material that allows to cool the surface of the building, even when exposed to the sun. On the other hand, they have designed a structure to eliminate accumulated heat and thus improve air circulation on the facade by vertical dissipating modules. In addition, they have developed a system to easily adapt to different types of construction. The possibilities. Since the investigation they have detailed that the implementation of these modules in residential and commercial buildings would mean a reduction in energy consumption aimed at refreshing the environment. In addition, in cities with the large amount of solar panels that are being installed and The urban heat island effectthis new system will help mitigate high temperatures from these factors. However, the researchers, who are optimistic, have explained the challenges they have to overcome and how they should observe the long -term application. However, they have added that this technology represents a step forward in the fight against climate change and the design of more sustainable cities. Any other alternative? In the search for sustainable solutions for refrigeration without energy consumption, researchers from different parts of the world are betting on different approaches. An interesting example comes from Indiawhere a system based on recycled clay has been developed. Inspired by botijo ​​technology, this system uses clay cylinders to reduce the ambient temperature by up to 15ºC by evaporation of water, without the need for air conditioning.

China is raising an unprecedented dam where millions of people live. The problem is seismic activity

by

Before finishing 2024 we advanced what was known about China’s last megonstruction. Actually, we could not talk about “another” as if it were something else in a long list, because it is possibly one of the most ambitious projects that are reminded of the nation: a super prey so monumental that would leave The three throats relegated to the background, producing three times more energy than the spectacular structure of more than two kilometers long. Of course, there is some problem. The superpress. It is a reality: China advances with the construction of the Motuo Superpress in Tibetan unprecedented infrastructure project that, if completed, will become the largest hydroelectric power plant in the world taking advantage of an abrupt slope of 2,800 meters, exceeding the capacity of the three throats dam (currently the biggest in the world). Located in The Grand Canyon of Yarlung Tsangpoon the border with India, the dam has aroused environmental, geopolitical and humanitarian concerns, especially due to the lack of transparency of Beijing about its development. Experts warn that the project represents a “water pump” for millions of people in India and Bangladesh. Seismic risks. The Tibet is One of the most seismically active regions on the planetit has been known for a long time because it is located in the collision of the Indian plaque and the Euroasy Plate. In fact, a recent 7.1 magnitude earthquake in Shigatse It caused damage to five hydroelectric dams and the death of 134 people, demonstrating how vulnerable infrastructure in the region is. Although Motuo’s work can be designed to withstand earthquakes, landslides and mud alluds could serve as a fuse and unleash, representing a direct threat to nearby populations. We speak, again, millions of people. This risk is aggravated by the phenomenon of Seismicity induced by reservoirs (RTS)where the weight of accumulated water in large dams can trigger earthquakes. An example is the zipingpu damwhose construction was followed by Sichuan’s devastating earthquake in 2008 which charged 87,000 lives. In addition, sediment retention by the dam could reduce the fertility of the soil downstream, causing erosion in the rivers and coasts of India and Bangladesh. Gran_Cañón Yarlung Tsangpo Environmental impact. The dam too would alter the water and climatic patterns Crucial for agriculture in the region. The Tibet, where Brahmaputra is born, is one of the most biodiverse regions of the world and a key regulator of Asian climate. The construction of the superpress could, for example, alter the monsoon rainfallwith devastating effects for agriculture in India and Bangladesh. In addition, the ecological impact of Chinese megaemblses is already evident in other international rivers, Like the Mekong, where the dams have caused droughts recurring and the intrusion of salt water in agricultural deltas. Impact between the premises and (des) information. It is another leg that must tie the project. The Tibet is under a strong control of the Chinese Communist Party, so the magnitude of the displacement of Tibetans that will require the work is not known. In this regard, Beijing has not revealed details about costs (It is estimated that total investment will exceed 130,000 million euros), The companies involved or the number of people who will be relocated. And if we are guided by other cases in Chinese provinces, protests against hydroelectric projects have been repressedit is suggested that any opposition in the Tibet will be silenced. Geopolitics of a superpress. He Brahmaputrawhich flows to India and Bangladesh, is a vital artery for millions of people. Again, that lack of Chinese transparency has generated distrust in New Delhi and Daca, whose scientists have demanded access to hydrological data to evaluate the risks of the work. India, meanwhile, Fears China use river control as a geopolitical weaponrestricting or diverting the flow in case of conflicts. Thus, and in the face of uncertainty, some Indian officials have proposed an alternative: Build a dam in a Brahmaputra tributary to counteract possible flow reductionsalthough this solution does not seem ideal and could also harm the ecology of the region. Imminent risk. Nikei had this week That the possibility of a catastrophic collapse is not a simple speculation. China has suffered hundreds of dam failures throughout its historyincluding the worst disaster ever registered: The collapse in cascade of the Banqiao dam And another 61 dams in 1975, an event that caused 85,000 direct deaths and displaced 11 million people. Even The three throats dam was on the verge of collapse in 2020endangering 400 million people. Therefore, if a strong earthquake hit the region and cause the rupture of the superpress, Millions of people in the Brahmaputra Valley in India and Bangladesh could be affected by catastrophic floods, aggravating. In addition, geopolitical and humanitarian tensions in the region. If you want also, it is feasible to think that with this mega -Obra, China would not only reinforce its control over the water resources of Asia, but also converting Brahmaputra into a geopolitical weaponincreasing their pressure capacity over their neighbors.

A new estimate of the Hubble constant delves into the problem

by

The “Hubble voltage”It is one of the greatest enigmas of contemporary cosmology. It refers to the fact that the increasingly precise measurements of the speed at which the universe disagrees expands. And not We have a lot of idea of why. Faster Now a new study has led Hubble tension to a new maximum. The work indicates that the observed acceleration of the universe is greater than what today’s physical models could explain. Theory and practice. There are two forms of measure the expansion of the universe. The first is based on the cosmic microwave background (CMB), a remaining radiation of the process that we know as big Bang. By measuring fluctuations in this background, it is obtained An estimate of the expansion speed of about 67 kilometers per second by Megaparsec (km/s/mpc), an expansion speed according to what the generally accepted cosmological models estimate. On the other hand, observations of the nearest universe tell another story. The cefaids are stars whose brightness is inversely related to the frequency with which they press. This allowed astronomers to create a “cosmic ladder” calibrating step to step the measurements of distances to increasingly distant objects in the cosmos. The problem is that this other measure estimates a significantly higher expansion speed: about 74 km/s/mpc. From tension to the crisis. The new study has deepened this discrepancy. The new measure based on the “cosmic ladder” has estimated an expansion rate even greater than the average of the previous measurements: about 76.5 km/s/mpc. This has led the team to point out that “The tension has become a crisis.” The step that was missing. The team responsible for the study created its own “cosmic ladder” from the DESI collaboration data (Dark Energy Spectroscopic Instrument). This instrument monitor about 100,000 distant galaxies thanks to 5,000 robots with fiber optic sensors that monitor space. The team responsible for the study had to “anchor” these data to our immediate vicinity, that is, put the first step of the “cosmic ladder” with which to measure the changes observed by DESI in its follow -up of these galaxies. To do this, he resorted to the cluster of the comma, one of the galactic clusters closest to the Milky Way. Supernovas To measure the distance to this cluster, the team turned to the light curves of 12 IA type supernovae located within your own Cluster. This type of supernovas shines in a very predictable way, so its apparent brightness gives us a good measure of its real distance. The details of the process can be consulted In an article Posted in the magazine The Astrophysical Journal Letters. The search continues. These types of intrigues generate great interest in the scientific community since it is through cracks in ancient models that are usually opened by the discovery of new theories. “It’s exciting,” explain those responsible for the study. But the truth is that, for now, we have few clues that allow us to solve this issue, either through substantial changes in contemporary models, either through changes in the paradigm.

Elon Musk says he will rescue the two astronauts stranded in the space at Trump. The problem is that

by

A incendiary message. “The president of the United States has asked Spacex to bring the two astronauts stranded at the International Space Station as soon as possible,” Elon Musk wrote In his profile of X. “It is terrible that the Biden administration has left them there for so long.” After 20 minutes, more than one million people have seen the message, which Musk apostilled answering “true” to the following answer: “The hatred they had was greater than their desire to rescue those astronauts.” A little context. In June 2024, two astronauts arrived at the International Space Station aboard the Starliner spacecraft, Boeing’s alternative to the Crew Dragon of Spacex. The ship had to spend a week in orbit before returning to Earth, but A failure in the propulsion system During the first leg he made three months undergoing And finally I would go empty. Elon Musk’s X messages about astronauts Elon Musk lies. No one will be surprised at this point that Musk publishes propaganda in his X profile, but the message misrepresent the reality in a particularly fantasy way. While it is true that astronauts Butch Wilmore and Suni Williams are still in space since June, they are not stranded. SPACEX CREW-9 MISSION took off in September 2024long before Trump assumed the presidency, with two empty seats to bring them back. So why do they continue in the ISS? It was the plan provided by NASA. Wilmore and Williams were reallocated to the CREW-9 mission and became part of the permanent crew of the International Space Station. Williams is, in fact, the commander of expedition 72, and He has just taken a space walk As part of your tasks. That NASA did not ask Spacex to look for them immediately has nothing to do with the hatred of Musk, but that there was no crew dragon to immediately available. The most logical solution was to get two astronauts out of the next round trip (the CREW-9 mission) to leave two free seats. And now what? The return of the CREW-9 mission is scheduled for the end of March 2025. So far, the expected thing was that Wilmore and Williams return along with their mission partners, the American Nick Hague and the Russian Aleksandr Gorbunov, in March or maybe in April. But Musk’s message suggests that perhaps his return goes ahead. As for the Starliner, NASA canceled the flight that had hired Boeing By 2025. The two astronaut rotations of this year will be in charge of Spacex while Boeing continues to analyze what could fail in its first manned flight and how it plans to solve it.

Deepseek is the fashion model. The problem is that nobody knows very well what you are doing with our data

by

If you are a user of Chatgptit is likely that in the last week you have tried Deepseek. He Chinese ia chatbot It is so promising that It has become a serious threat to many of the American technological giants. Not only is it an open source proposal that can work very well at home (in a certain hardware), but also has a free online version that, at least for the moment, allows unlimited consultations. There is also one Payment API whose rates are very competitive. When we use chatbots like Deepseek we usually share a lot of information. These tools have become allies when planning vacations, summarizing documents, making budgets, analyzing images, among other things. Their language models swallow every word that we introduce to give us the answers we are looking for or an approach that we can refine to Prompts. What do they do with our data? Now, after the initial crush of discovering a new application of ia, let’s ask ourselves What happens to our data. Do they disappear after being processed by the model? Do we give them perpetuity to a company that we don’t even know? Are they stored as a treasure for training future iterations of the model? Certainly there are many questions, many, but they are not completely new. We already asked ourselves many of these questions when Chatgpt achieved popularity. Perhaps we did not ask ourselves the questions, but several European regulators were asked, which forced the company led by Sam Altman to make some changes to continue operating in certain countries of the block. Deepseek is the new star, and sooner or later these questions should appear on the scene. In the midst of so many questions there are some certainties: Deepseek collects a huge amount of data. This is probably not a surprise for some, but for others who have just started using chatbot. To have more clarity about the PRIVACY PRACTICES OF THE CHINISH COMPANY we can consult its page of Privacy Policy. Let’s start at the beginning, Hangzhou Deepseek Artificial Intelligence Co., Ltd. and Beijing Deepseek Artificial Intelligence Co., Ltd. collect information on the profile of users, such as username, date of birth (if applicable), address of email and/or telephone number and password. Our chats also collect, that is, texts, audios, charged files, comments, history. Everything goes to these companies. Suppose you have a question about Depseek and use the contact paths to talk to them. Well, the aforementioned organizations will also collect all the information you send. From identity or age tests, comments or consultations about the service. Everything mentioned so far is within a category called “Information you provide.” Within the range of information collected by companies behind Depseek we find another category called “automatically collected information.” Here they are made with our device model, operating system (and the language of the), IP address, cookies and diagnostic data and performance. They will also capture the keys of keys, and everything will be associated with a device ID and a user ID. It is not possible to quote our data, but there are no doubt that they are valuable. One way to measure its value is to size everything they drive. First, Depseek uses the data collected to train your AI models. Companies also talk about “interactions supervision”, and at this point we are not sure if there are humans analyzing conversations. In the documents of the companies we find other interesting information, such as that “review the entries and exits of the user and other information to protect the security and well -being” of the community. They also collect data to comply with legal obligations, to “carry out public interest tasks” and to notify changes in services.
