The US electrical grid does not support so many data centers so they have had an idea: disconnect them to avoid blackouts

by

One third of all data centers in the world They are in the US and that is putting a huge burden on the electrical grid. One of the consequences that consumers are noticing is the price increases on the invoice, But electricity operators already foresee another problem: blackouts. What is happening. They tell it in WSJ. The US power grid is beginning to become strained, with grid operators expecting blackouts during periods of high demand. The solution they propose to avoid this is to make data centers disconnect from the network and use their own energy reserves temporarily. The technology companies have not been amused and talk about “discriminatory measures.” Why is it important. In 2023, data centers already consumed 4% of all the country’s electricity and the forecasts are that by 2028 that percentage will increase to 12%. The electrical grid is not prepared to support so much demand and, although it is already expanding, the pace of construction of new data centers is faster. Network operators face a difficult dilemma: powering data centers while maintaining supply to consumers. ‘Kill switch’. PJM Interconnection It is the organization that oversees the energy market in the Midwest, where they have already suffered from the problem of price increases. The concern that blackouts will occur is on the table and PJM has proposed that technology companies create their own energy sources or accept that their supply will be cut off if the network becomes too saturated. They are not the only ones who have raised something like this. With demand expected to double by 2035, Texas passed a law last year that contemplates a ‘kill switch’ that allows large consumers, such as data centers, to be disconnected at times when the network is under “extreme stress.” What the technologies say. As we said, the companies that own these data centers have not been very happy with the proposal. The Data Center Coalitionof which companies such as Google, Microsoft and AWS are part, have stated that the proposal is discriminatory since data centers need a reliable and stable network. They also warn that depending on their own energy reserves could have a negative environmental impact, by forcing them to use solutions such as diesel generators. Waiting times. There is an intermediate scenario in which technology companies can obtain benefits if they accept these conditions. As the electrical infrastructure does not support so much demand, data centers have to wait several years to be connected to the network, normally between 3 and 5 years, although there have been cases up to 8 years. Southwest Power Pool, the grid operator in Texas, has offered data centers a deal: give them access to the grid sooner in exchange for agreeing to be disconnected during times of high demand. According to a recent study Funded by Google, data centers that have more flexible connections (i.e., those that build their own power sources and accept temporary disconnections) typically connect to the grid several years faster than those that do not. Bring your own energy. Despite the reluctance towards that off button, generating your own energy is the most realistic solution and the one towards which the industry seems to be moving. Google recently bought an electrical company in order to obtain its own energy. Others big tech Amazon, Microsoft, Oracle or xAI are also exploring create your own energy solutions such as natural gas and solar panels.

two different versions, millions of accounts in check and one good idea

If you’ve received a message from Instagram asking you to reset your password in the last few days, you’re not the only one. A quick look to Reddit or social networks like X/Twitter evidence that it is something quite common at the beginning of 2026. In fact, there are those who assures have received these messages on several occasions this week, including a few times a day. what has happened. Numerous Instagram users have detected unusual activity related to mass password reset requests. More specifically, they were receiving password reset emails that looked legitimate without having requested it first. Two versions that explain it. Following that massive request and speculation, on January 9, the antivirus software company Malwarebytes made public a data leak. Just a few hours ago, Instagram pronounced. The versions of each one: According to Malwarebytes, a group of cybercriminals “stole sensitive information from 17.5 million Instagram accounts, including usernames, physical addresses, phone numbers, email addresses and more.” It is not mere scraping, but an authentic doxing kit found on a popular cybercrime forum. From here, there were two options: either we were facing an automated brute force attack where legitimate “I forgot my password” emails were generated and, within the chaos, a malicious email was sent so that you click on a false link. Or that Meta had executed a defensive Instagram reset of those accounts it considers compromised. According to Instagram, they have fixed an issue that “allowed a third party to request password reset emails for some people. There was no breach of our systems and your Instagram accounts are secure.” He closed the explanation with an apology for the inconvenience. Tap to go to the post Why is it important. Instagram minimizes the impact of this incident by calling it a “software problem” and not a systems breach since technically, if they did not enter their servers, they do not consider it a hack. In any case, this alleged data leak contains usernames, real names, physical addresses, phone numbers, and email addresses. The level of risk is high insofar as this exposure of confidential personal information is of such caliber that it breaks the barrier between the digital and the physical. Exposing who you are online also jeopardizes real-world security. The reports detail that parts of that database are being marketed on the black market, sorting them into batches based on countries and numbers of followers. That is, prioritizing high-profile accounts such as influencers or business accounts. What should you do now. To begin with, under no circumstances touch on the links that appear in the emails, no matter how real they may seem. From here: Change Instagram password from the app, in ‘Settings and activity’ > ‘Account Center’ > ‘Password and security’ > ‘Change password’. Use a long, robust and unique one. Configure the Two-Step Authentication that you will find in the ‘Password and Security’ section of the app, following the previous route. Better avoid the SMS option. Likewise, it is advisable to log out on all devices and, in case you have received several messages, check if the emails are truly from Instagram through the ‘Emails from Instagram’ option in the settings. If you detect any, delete them.

Washing chicken “to clean it” sounds hygienic. Science says it’s a bad idea (and very dangerous)

by

“Chicken should never be washed.” This time, it was Higinio Gómez (one of the most renowned gourmet polleros in Spain) who reopened the debate in an interview in El País. But the issue is recurrent and inexplicably generates very opposing positions: from those convinced that washing chicken is a way to “remove germs or dirt” to those who, rightly, say that it is a terrible idea. But, as Gómez himself would say in his establishment, ‘let’s go in parts’. What’s wrong with the chicken? Let’s start with the most basic: nothing happens to the chicken. The risk linked to ‘washing chicken’ has nothing to do with the chicken itself. It has to do with cross contamination: the bacteria from raw chicken (which would be eliminated during preparation) transfer to the hands, sink, countertops, and various utensils. Often, in fact, when washing chicken we end up putting those bacteria in foods that are ready to eat. The EFSA estimated in billions of euros annually the impact of pollution Campylobacter (a bug especially linked to chicken). Sometimes it’s because you cook it wrong, yes; but often it is due to handling raw food without any type of rigor. What the evidence says. In a now classic observational study by the North American USDA, was discovered that, in fact, what I just explained was what really happened: among those who washed the chicken, 60% contaminated the sink and up to 26% ended up transferring bacteria to the salad. And, in fact, we already have experimental studies that explain the mechanism: beyond the obvious, “washing generates droplets capable of transferring bacteria and increasing environmental pollution” And why do people insist on washing it? That’s a good question with numerous answers: from the cultural and historical heritage (after all, when the chicken was slaughtered at home, washing did make more sense) to a lack of sense of control that ends up turning against us. Let’s be practical: How to avoid cross contamination when cooking chicken? Separate raw chicken from other foods: It is a good idea to keep the chicken raw separated from other foods. This is always true, but especially with all those that are consumed raw (such as fruits and vegetables). Use different utensils: We have talked about it with the cutting boardsbut it is especially effective advice with knives and other utensils. In fact, the recommendation is that, if we do not have several sets of utensils, wash them carefully between uses with hot water and soap. Wash hands and surfaces thoroughly: After handling raw chicken, you should not only wash your hands with soap and hot water for at least 20 seconds; Instead, we should disinfect all surfaces with which it has been in contact.

data centers in space are a horrible idea

by

Artificial intelligence has turned energy into the new technological bottleneck. And faced with that limit, some of the largest companies in the world have begun to look up. To give some examples, Jeff Bezos has spoken of “giant AI clusters orbiting the planet” in a decade or two. Google has experienced with running artificial intelligence calculations on solar-powered satellites. Nvidia supports startups who want to launch GPUs into space. Even OpenAI has tried the purchase of a rocket company to ensure his own path off Earth. The promise is seductive: solar data centers running around the clock, without power grids or cooling towers. The problem is that, when you move from the story to physics, engineering and numbers, the idea begins to break down. Data centers in space. There is a question that surrounds this issue: why do technology companies want to send data centers to space? The motivation at first glance is clear. According to data from the International Energy Agencydata center electricity consumption could double by 2030, driven by the explosion of generative AI. Training and running models like ChatGPT, Gemini or Claude requires massive amounts of electricity and huge volumes of water for cooling. In many places, these projects are already running into local opposition or physical network limits. In this context, space appears as a tempting solution. In certain orbits, solar panels can receive almost constant light, without clouds or night cycles. Besides, as Bezos and other defenders explainthe vacuum of space seems to offer an ideal environment to dissipate heat without resorting to cooling towers or millions of liters of fresh water. According to this argument, space data centers would be more efficient, more sustainable and, over time, even cheaper than terrestrial ones. For some executiveswould not be an eccentricity, but the “natural evolution” of an infrastructure that already began with communications satellites. When engineers raise their hands. Faced with the enthusiasm of corporate statements, several space engineering experts have been much more forceful. In one of the most cited texts on the subjecta former NASA engineer with a PhD in space electronics and direct experience in AI infrastructure at Google sums up his position bluntly: “This is a terrible idea and it doesn’t make any sense.” His criticism is not ideological, but technical. And it starts with the first great myth, the supposed abundance of energy in space. Solar energy is not magic. The largest solar system ever deployed outside of Earth is the International Space Station. According to NASA dataits panels cover about 2,500 square meters and, under ideal conditions, generate between 84 and 120 kilowatts of power, a part of which is used to charge batteries for periods in the shade. to put it in contexta single modern GPU for AI consumes on the order of 700 watts, and in practice around 1 kilowatt when losses and auxiliary systems are taken into account. With those figures, an infrastructure the size of the ISS could barely power a few hundred GPUs. As this engineer explainsa modern data center can house tens or hundreds of thousands of GPUs. Matching that capability would require launching hundreds of structures the size—and complexity—of the International Space Station. And even then, each would be equivalent to just a few racks of terrestrial servers. Furthermore, the nuclear alternative does not solve the problem either since the nuclear generators used in space, RTGs, produce between 50 and 150 watts. In other words, not even enough to power a single GPU. Space is not a refrigerator. The second big argument against orbital data centers is cooling. It is frequently repeated that the space is cold, and that this would make it easier to dissipate heat from the servers. According to engineers, this is one of the most misleading ideas in the entire debate. On Earth, cooling is based on convection: air or water carries away heat. In the vacuum of space, convection does not exist. All heat must be removed by radiation, a much less efficient process that requires enormous surfaces. NASA itself offers a compelling examplethe active thermal control system of the International Space Station. It is an extremely complex network of ammonia circuits, pumps, exchangers and giant radiators. And even so, its dissipation capacity is in the order of tens of kilowatts. According to the calculations of the aforementioned engineercooling the heat generated by high-performance GPUs in space would require radiators even larger than the solar panels that power them. The result would be a colossal satellite, larger and more complex than the ISS, to carry out a task that is solved much more simply on Earth. And there is a third factor: radiation. In orbit, electronics are exposed to charged particles that can cause bit errors, unexpected reboots, or permanent damage to chips. Although some tests, such as those carried out by Google with its TPUs, show that certain components can withstand high doses, the failures do not disappear, they only multiply. Shielding systems reduces risk, but adds mass. And each extra kilo increases the cost of the launch. Furthermore, AI hardware has a very short lifespan, as it becomes obsolete within a few years. On Earth it is replaced; In space, no. As critics point outan orbital data center would have to operate for many years to amortize its cost, but it would do so with hardware that is left behind much sooner. So why do they keep insisting? The answer seems to lie less in current engineering and more in long-term strategy. All of these projects depend on the condition that launch costs fall drastically. Some estimatesthey talk about thresholds of about 200 dollars per kilo so that space data centers can compete economically with terrestrial ones. That scenario relies on fully reusable rockets like Starship, which have not yet demonstrated that capability on an operational scale. Meanwhile, terrestrial renewable energies they continue to get cheaperand storage systems They improve year after year. Furthermore, the story of the space fulfills another function because it positions … Read more

The US bans Chinese drones and turns DJI into the new Huawei. It’s an absolutely crazy idea.

by

The Federal Communications Commission (FCC) of the United States has decided ban all drones and critical components of these vehicles that have been manufactured in foreign countries. In addition to this, he has vetoed any team of communication and video surveillance from the largest Chinese manufacturers, and there is one name above all others: DJI. It’s another shot in the foot for the Trump administration. what has happened. Does almost a decade that some government officials in the US were asking for a veto on drones manufactured by Chinese companies, and that veto is now official. The FCC decision It will prevent this body from authorizing drones or critical drone components, something that is essential to be able to import them into the United States. The measure clearly affects DJI, which becomes the new Huaweialthough there is another firm, Autel, that will also be greatly impacted by the decision. Both come to form part of the so-called “covered list”. The reason is the usual one: to protect national security. It only affects (for now) future drones. The existing drones They will not be affected for the moment by the veto and their users will be able to continue using them. Stores that had models in their inventory and warehouses will be able to sell them normally, as the FCC’s action focuses specifically on future models. Thus, the decision is not retroactive, but that could change in the future and affect many models. What DJI says. Those responsible for DJI indicate in The Wall Street Journal that the company is prepared to be audited and highlights that independent analyzes have indicated that its products are completely safe. “DJI’s data security concerns are not based on evidence and instead reflect protectionism, contrary to the principles of an open market.” Drone pilots cry out to the sky. There are nearly half a million certified drone pilots in the United States, and in this segment between 70 and 90% of commercial drones used by local governments and hobbyists come from DJI. The measure therefore has an enormous impact on this entire industry in the United States. Many of these pilots are collecting drones and components to mitigate the impact of the measure. bad future. Greg Reverdiau, co-founder of the Pilot Institute in Arizona, conducted a survey in which 8,000 pilots participated. 43% indicated that the veto would be “extremely negative” and “potentially a cause of business closure”, and nearly 85% said they could stay in business for up to two years due to the prospect of not being able to access future DJI equipment and components. As this expert said, “People don’t buy DJI drones because it’s Chinese, they buy it because it’s available, very affordable, and capable.” DJI has no competition. And less, American. Eric Ebert, owner of a construction firm and user of these drones, explained the problem. “I’m American through and through. I drive a Chebrolet truck. But American drones can’t compete.” Ebert has a team of seven drone pilots who monitor wind turbine and solar panel installations. These weeks they have not stopped hoarding DJI drones and components “knowing what was going to come our way in 2026.” Protectionism…One of the companies that will benefit from the measure is Brinc Drones, a Seattle firm that sells them to more than 700 state agencies. Blake Resnick, its founder, explained that “it is impossible to compete with DJI unless you are subsidized by the state.” …and rear doors. In November XTI Aerospace, which makes helicopters, acquired a DJI distributor called Drone Nerds and also Anzu Robotics, which makes drones by licensing technology from DJI. As part of the agreement, the drone component manufacturing firm Unusual Machines invested 25 million. Guess who is a shareholder and board member of Unusual Machines: Donald Trump Jr, President Trump’s son. Image | jonas In Xataka | China conquered us with its cheap drones.

Toledo has stretched its Christmas season to last 49 days and attract more tourists. Some neighbors think it’s a bad idea.

by

Day of celebration for some. Outrageous to others. The one of Friday, November 21 It was a night of conflicting feelings in Toledo. While the City Council celebrated the official switching on of its Christmas lights (the early risers of its history) a group of neighbors gathered in the historic center to protest the ‘bill’ of mass Christmas tourism. For them, long celebrations of 49 days (until January 8) marked by crowds and difficulties in continuing with their lives. The (mega)Christmas. They do not reach the height of Vigo, which turned on its lights November 15 and probably won’t turn them off until well into Januarybut Christmas in Toledo will be much longer than usual this year. The City Council decided advance one week the implementation of its lighting and redoubling its commitment to attract tourists: if in 2024 the red button is pressed on November 29in 2025 it was activated the 21stwhen they started to shine 1.1 million LEDs100,000 more than a year ago. The result: Christmas brighter and more extensive that are remembered in the Castilian-La Mancha town. A percentage: 94.25%. The bet seems to have gone well for the City Council, which a few days ago he stuck out his chest due to the flood of tourists it received during the Constitution and Immaculate Bridge. According to the data provided by its Tourism Councilor, the city achieved a hotel occupancy of 94.25%, which, he emphasizes, consolidates it as “one of the preferred destinations” for visitors. As a reference, the year-on-year increase in visits has exceeded 47%. Visitors came to Toledo from Madrid, Valencia, Barcelona, ​​Seville, other towns in the province of Toledo and even travelers from France, Italy, Argentina and the USA. The tourist boom was not limited to just the long weekend. Although Christmas has not yet started as such, The Spanish posted last week a series of photos that show that the historic center of the city was crowded again on the weekend of December 13 and 14. One coin, two sides. Greater influx of visitors usually translates (not always) in more business for restaurants, more guests in hotels and a greater number of potential clients for commerce. In Toledo, however, there are those who has raised his voice to warn that all this does not come for free to the city. And not just because of the cost of Christmas decorations. The same Friday that the mayor presided over the ceremony a group of residents of the historic center turning on the lights they concentrated to denounce the impact that crowds and mass tourism have on their lives. Is it something new? No. The debate on tourism (and its impact) it’s not new in Toledo. In fact, a few months ago the City Council gave the green light to an ordinance that seeks precisely to “promote a balanced coexistence between visitors and neighbors” and sets limits to the use of megaphones or tourist groups. This Christmas, however, the patience of the neighbors seems to have been exhausted. First for the phenomenon of Christmas tourismwhich transcends to other areas of Spain. Second, because this year Toledo has decided stretch your holidays. “Dangerous streets”. The most critical residents warn of the saturation of the historic center and how this affects their daily lives. After all, those who live in tourist areas are forced to continue with their routines (working, shopping, walking the dog…) with the streets crowded with visitors. “There are a lot of people circulating. I understand that they come to do tourism, to enjoy themselves, but they should be aware that there are people living there who are carrying out their normal daily lives,” explains to elDiario Natacha, a neighbor of the Historic Center who complains about the “overcrowding” on weekends. One of her neighbors, Carmen, goes even further and warns: “The streets are becoming dangerous.” And what is the solution? There is who poses distribute the tourist offer throughout the town to decongest the historic center and seek a “more livable” city model. One thing is clear: Toledo is forced to deal with two realities that seem to collide with each other. A, the discomfort on the part of its inhabitants with the agglomerations, something that is clear with their protests. The other reality is that tourism is a fundamental (and inalienable) source of wealth for the region. In 2023, for example, it assumed 7.3% of GDP of Castilla-La Mancha. Beyond Toledo. Toledo is not the only city that has encountered such a dilemma. In Vigo too have registered protests of neighbors and groups critical of the Christmas lights phenomenon, which according to the City Council attracts several million of visitors to the city in a matter of two months. Perhaps the most critical voice is that of the Vigo Central Zone Neighborhood Association, which complaint that the holidays become “a period of circulatory chaos, mobility problems, security problems, dirt and noise and light pollution in the heart of the city.” Your complaints already They have arrived at the court.

The “my cat is fat” problem is so common that the industry has come up with an idea: “Ozempic for cats”

by

In just a few years, drugs such as Ozempic, Wegovy or Mounjaro have gone from being discreet treatments for diabetes to become a great social phenomenon. His promise—lose weight through a simple weekly injection—has opened a new chapter in human medicine. Now, this pharmacological revolution is beginning to expand beyond people: cats could be the next to receive an adapted version of these treatments. Goodbye fat cats. Okava Pharmaceuticals, a San Francisco company dedicated to chronic diseases in companion animals, has started a pioneering clinical trial called MEOW-1whose objective is to evaluate the safety and effectiveness of OKV-119, a subdermal implant capable of releasing exenatide—a GLP-1 agonist—sustained for months in overweight or obese cats. The intervention aims to simplify a treatment that, in humans, usually requires weekly injections. Here, everything comes down to a single gesture. “You insert the capsule under the skin, and six months later you come back, and the cat has lost weight. It’s like magic,” says Chen Gilor, the veterinarian responsible for the study. speaking to the New York Times. A pioneering study. Okava’s interests did not arise out of nowhere. Prior to MEOW-1, the company evaluated prototypes of the implant in two preliminary studies. A work published in Frontiers in Veterinary Science demonstrated that the OKV-119 implant could be easily implanted and removed, that it was well tolerated, and that its plasma levels of exenatide correlated with weight reduction in healthy cats for more than one month. Subsequently, research published in BMC Veterinary Research delved into this line: they implanted five cats with the designed prototype for 84 days, what they observed is that during that period stable levels of exenatide were maintained and four of them reduced at least 5% of their body weight, along with a lower caloric intake. These results motivated the move to a trial in real obese cats, which Okava plans to run this summer. According to the companyMEOW-1 will be the first formal feline weight loss study based on GLP-1 agonists. How does the implant work? OKV-119 uses the NanoPortal platformdeveloped by Vivani Medical. According to scientific studiesthis technology uses: a titanium reservoir, a membrane with nanotubes that regulate the passage of the drug, and a system designed to ensure a constant and prolonged release without pronounced peaks. Furthermore, this type of administration allows us to overcome the main difficulty associated with GLP-1 in veterinary medicine: lack of adherence. Studies indicate that giving repeated injections to a cat is complex, stressful and can drastically reduce the continuity of treatment, ithe same as what happens in people with injectable drugs. The implant seeks to solve that problem with an approach one-and-done: a subdermal insertion in a veterinary office, without daily intervention by the caregiver. According to The New York Timesthere are veterinarians who already use human GLP-1 agonists off-label in diabetic cats, but its cost and need for frequent administration limit its use. Hence the relevance of a device that could keep the medication active for half a year. But only in cats? Although MEOW-1 focuses exclusively on felines, Okava and Vivani have confirmed an expansion of the project to dogs, another species with obesity rates greater than 50% in the United States. The company states that its goal is to reproduce in dogs the metabolic effects observed in cats: improved insulin sensitivity, reduction in fat mass and greater energy efficiency. With the expectation that these changes may even promote healthier aging. With both markets, the commercial potential is evident. According to estimates collected in Xatakathe global human obesity drug sector could exceed $100 billion by 2030. Veterinary medicine would be a new frontier. Feline obesity is a global epidemic. The interest in an “Ozempic for cats” is not a whim. It is an answer to a growing problem. A review published in Journal of Feline Medicine and Surgery places the prevalence of feline overweight between 40% and 63%, although it continues to increase. When you ask veterinariansthe same patterns almost always appear: cats that live exclusively indoors, very little movement, food available all day, too many treats, sterilization and a very common problem: many owners are not aware that their cat is gaining weight. The consequences are not minor: insulin resistance, diabetes, joint problems, urinary diseases, anesthetic complications and liver disorders, in addition to a reduction in life expectancy. And the latest evidence goes even further. A proteomic analysis that evaluated 288 proteins in cats with obesity found important changes in inflammatory processes, in the complement system, in coagulation pathways and in lipid metabolism. In other words, feline obesity affects the entire organism, it is not just a “fat cat.” Many open questions. Although MEOW-1 is moving forward with positive expectations, mass adoption of an “Ozempic for cats” is far from a fact. The first unknown is the price. In humans, GLP-1 cost several hundred euros a month, and it is not clear whether a semi-annual release veterinary implant will really be affordable for the majority of caregivers. Cost could become the main barrier to entry, especially considering that feline obesity is a common problem, but not always perceived as a health priority. The second uncertainty has to do with the available scientific evidence. So far, studies on OKV-119 have been preliminary and with extremely small samples (between 5 and 15 cats). They work, yes, but we still don’t know what will happen on a large scale, or how animals with diseases or in varied home environments will respond. Finally, there is the question of scientific independence. For now, all published studies on OKV-119 come from teams linked to Okava or Vivani, the companies developing the implant. There is no independent, large-scale evidence, and this matches a pattern already observed in human GLP-1where much of the initial research is driven by the industry itself. A new era in feline medicine? The questions surrounding this new milestone in the treatment of feline obesity are piling up: will these preliminary results be enough to justify regulatory approval? Will caregivers change … Read more

The US has insisted that TSMC manufacture chips in Arizona. The reality: it is a disastrous idea

by

TSMC, the world’s largest semiconductor maker, has long been pushing for unprecedented expansion outside Taiwan. The initiative includes large projects in the United States, Japan and Germany, but does not respond to market demand, but rather to geopolitical pressure and a chip war that wants to try to “repatriate” this type of process. It’s a terrible idea. Morris Chang knows it’s a mistake. Despite the political urgency, the economic viability of these factories abroad has been questioned by TSMC founder Dr. Morris Chang. He already had the previous experience with the WafertTech factory in the US in 1996, and has qualified Arizona initiative as “a very expensive exercise in futility” Everything one hour away. Chang’s skepticism is based on the belief that TSMC’s operations and profitability are intrinsically dependent on its ecosystem, which is entirely concentrated in Taiwan. The Hsinchu Science Park “cluster” allows hundreds of technology partners to operate within a “one-hour” radius, facilitating problem resolution and providing ultra-fast logistics and unparalleled coordination. TSMC is still 90% Taiwanese. Despite that global expansion, TSMC remains deeply Taiwanese, with more than 90% of its manufacturing capacity and nearly 90% of its employees on the island. That’s where your massive, highly trained and qualified engineering talent base is. That is again a key factor in its competitive advantage, and in fact the company has already warned its employees in the US that they should adhere to the work culture of the Taiwanese company. Arizona produces, but it is more expensive. That attempt to replicate Taiwanese efficiency in Arizona has revealed something important: although TSMC has achieved competitive performance in its first production runs with 4nm photolithography, the cost of the wafers is significantly higher. The local supply of raw materials and equipment remains insufficient, making the factory dependent on Asia and is a bottleneck for the efficiency of the production cycle. Skilled labor shortages and permitting and bureaucracy, which further slow things down, add considerable operational costs. Japan and Germany, next objectives. TSMC has two major expansion projects in Japan (JASM) and Germany (ESMC). These locations will focus on much less advanced photolithographic nodes (28/16 nm) and will focus on meeting the demand of some specialized customers such as Sony for image sensors in Japan or Bosch in Europe. The scale of these investments is less than that of Arizona, which aims to be the world’s largest advanced chip factory… if planned future phases are completed. A double edged sword. TSMC’s expansion has two sides. On the one hand, TSMC consolidates its technological leadership and its strategic role as a “silicon shield” against China. On the other hand, it generates internal anxiety about the possible “leakage” of advanced technology and talent that could weaken national sovereignty in the long term. US pressure even extended to veto the possibility of establishing a TSMC factory in the United Arab Emirates. TSMC does not expand by pleasure, but by pressure. Traditionally, TSMC only builds new factories in response to real demand from its customers. Here the reason has been very different, and geopolitical pressure has forced moves that the company would probably never have made otherwise. Here the different subsidy programs (CHIPS Act in the US, European Chip Law) try to repatriate part of the manufacturing and thus mitigate Asian dependence, but it’s not clear at all that they achieve it.

Putting four chickens in the yard seemed like a good idea to have cheap eggs. Bird flu just changed the rules of the game

by

From November 13, 2025, there is no poultry farm in the country that can be outdoors. With mass confinement, the Government wants to contain the spread of the H5N1 bird flu. And it makes sense: so far this season, 14 outbreaks have already been recorded in poultry, several in captive birds and dozens in wild birds. The problem is everything that falls under the radar. “What do I do with my chickens?” In Spain, at least from 2024, all chickens must be registered. And yes, that includes ‘self-consumption’ chickens; some animals that, according to the data, they represent only 0.77% of the census (but all experts know there are many more). A report from El País from the spring of this year confirmed that “the figures do not reflect reality and that a large part of self-consumers have birds (especially the ISA Brown species) without census.” This has meant that in a context in which self-consumption does not have inspections (and lives unaware of animal health regulation), the doubts and risks have grown exponentially. As Cristina García Casado explained in InfoLibrethe question most frequently asked by veterinarians across the country is “what do I do with my chickens?” And the answer is very simple: confine them. Because the regulations do not understand sizes: a backyard chicken infected by contact with a wild bird can be just as big a problem as any other type of chicken. Or maybe more. After all, the European authorities they continue to qualify the risk to the general population as low; but they raise it to low-moderate for people in direct contact with infected birds or contaminated environments. Having unmonitored poultry increases the risk to the “civilian” population and if we are realistic we will recognize that they cannot be monitored. The problem has names and surnames: at least when it comes to the flu, all those domestic pens have the same sanitary requirements, but much less infrastructure. The ‘boom’ of homemade eggs. We must remember that this does not happen in a vacuum. The truth is that in recent years we have lived a real ‘boom’ in self-consumption chickens. It is the confluence of the “happy chickens” movements with the response of many citizens to a price that does nothing but go up. According to the National Institute of Statistics, have gone up 15.9% so far this year and, according to the OCUthe growth has been 105% compared to 2021. And, be careful, we are not talking about a luxury product. We are talking about what may be one of the proteins cheaper and more accessible of the world. Faced with this ‘ovoflation’, the accounts are clear: “a hen costs about nine euros, it is easy to raise and maintain with fruit, vegetables and feed, and it lays an egg every 25 hours.” How can there not be a problem? What to do if I have a chicken coop for self-consumption? If we are in that situation (or are thinking about setting up our own domestic corral) there are some things to keep in mind: Whether larger or smaller, the corral must be registered in the REGA (General Registry of Livestock Operations). Implement confinement and biosecurity measures: separate chickens from any contact with wild birds; control inputs and outputs; record all changes in a log book. Improve cleaning conditions, more frequent bed renewal and tightening daily management protocols. Introduce wellness programs to contain the problems associated with a sedentary lifestyle. But, above all, be extremely vigilant. There are many warning signs (apathy, drop in production, high mortality or flu symptoms). Therefore, it is best to be alert. Anything can happen.

While we wait for solid-state batteries, the University of Córdoba has an idea for the electric car: human poop

by

The automotive industry has launched itself into electrification arms. Be with the hybrids, plug-ins either 100% electricthey all have batteries, and the key to convincing more users of make the jump from your combustion car is guarantee greater autonomy. The solid state batteries are one of the technologies in researchbut there are other very promising ones such as lithium-sulfur, and the University of Córdoba believes that there are two secret ingredients to improve the formula. Urine and excrement. Li-S. They are not new. We have been talking about the lithium sulfide batteriesand while we find the economy of scale necessary for solid-state ones to establish themselves, lithium-sulfur ones are one of the hopes for electric cars. They have twice the real energy density of lithium-ion, sulfur is extremely abundant and economical compared to critical materials such as cobalt or nickel, It is not something that China controlsit is safer because the risk of thermal runaway is lower and the environmental impact is reduced. They are not perfect, since the conductivity is low, the manufacturing processes are not as optimized as those of current alternatives and, above all, the current useful life is very limited: although they are moving forward In this sense, just 300-500 charge cycles compared to between 1,000 and 3,000 for lithium-ion batteries. However, as we say, they have become a promising technology, and the University of Córdoba wants one of the ingredients in the battery to be… poop. Batteries from waste. The Chemical Institute for Energy and the Environment, or IQUEMA, of the University of Córdoba has published a study in which they test the potential of sludge from a municipal treatment plant when converting it into activated carbon. It is an essential material for lithium-sulfur batteries, since it works as a conductor, and they consider it to be the answer to the challenge of optimizing the electrodes of these batteries. As we said, sulfur has advantages, but one of the great deficiencies is its conductivity index. This requires active carbon and other conductive matrices that are expensive to produce. But of course, if this conductive matrix is ​​created from waste that all cities in the world produce no matter what, things change. Villaviciosa de Córdoba. To do this, IQUEMA has used sludge from the wastewater station of Villaviciosa de Córdoba. This plant uses a treatment system that generates a sludge with an interesting composition to carry out the experiment: It is rich in organic matter. Also in metals, nitrogen and phosphorus. Combining them can create a material with a good electrochemical performance index. The process is as follows: Drying: the mud is dried and pulverized. Chemical modification: Potash is added as a chemical agent to make the material more porous. Pyrolysis: the mixture is subjected to temperatures of 800º to convert the organic matter into activated carbon. Mixture with sulfur: thus it is trapped in the active carbon matrix and the last step would be to integrate it into the battery electrodes. Promising. The researchers have found that the activated carbon obtained has ideal properties to be used as a material in these batteries. Its porous structure and nitrogen doping improve the transport of electrons and ions, and the resulting material has a high sulfur content. This allows the battery to have great electrochemical stability. That is to say, one of the big problems of this technology, the low conductivity of sulfur for the cathode, is something that mitigates the matrix created from the Villaviciosa de Córdoba sludge. And because its raw material is what it is, it is easier to recycle than other conventional batteries for which you have to develop tadjacent technologies for sustainability. According to the researchers, it is an avenue worth exploring because “triple the storage capacity of a lithium-ion battery”. “It is a great advance that we achieved from a waste that we considered problematic” – IQUEMA researchers Beyond the poop. Considering the results, it is likely that we will see more studies in the same direction. It is something that solves a double problem: the municipal waste management by converting it into a key material to solve one of the challenges of lithium-sulfur batteries. And the interesting thing is that IQUEMA has not remained only in the sludge of the sewage treatment plant. Previously explored the potential of agroindustrial byproductslike the olive pits and avocados, but also almond and pistachio shells. The problem is that these materials are already in demand in other sectors (such as composting or heating), and that is where the great advantage of human excrement lies: “no one” wants them.
