If you feel guilty every time you leave your dog home alone, science has an explanation (and a couple of solutions)

May 26, 2026 by usatoday24

Anyone who has a dog as a pet has probably faced a big problem when they grab their keys and coat and head out the door. This is nothing more than the whining and nervous pacing of an animal behind its owner that can end up barking or even destroying some object in the home due to the stress they feel when they are left alone and ‘abandoned’ under their conscience. However, science suggests that This separation anxiety is a bidirectional phenomenon. In two senses. As stated in different texts, leaving our pet alone not only triggers a peak of stress in the animal, but also generates a deep burden of guilt and anxiety in the human. And no, it is not that we are excessively humanizing our dogs, it is that our brains and theirs have developed an attachment bond that is comparable to that of interpersonal relationships. It’s not parenting. One idea we have in mind is that when a dog has anxiety when its owner leaves, for example, for work, it is the result of having had a very permissive childhood in which no animal restrictions were imposed. But today this has changed with important data. We can find these data in a large study published in 2020 on the canine population in Finland that revealed that between 14% and 20% Of dogs suffer from separation anxiety, they often have a strong fear of other stressors, such as loud noise. Why do they do it? Neither revenge nor general anger at having been left alone come into play here, but rather this behavior is linked to patterns of frustration and panic. Besides, there are some factors that predispose animals to have these problems, such as being male, coming from a shelter, having suffered early weaning or facing an environment that lacks predictability. In the human. Staying with only the reaction that the animal has, the truth is that it is a very short understatement. And here science has seen that owners also experience stress, difficulty concentrating at work or even cancel social plans to avoid the distress of leaving their pet alone. And here the bond that is generated between the human and the animal comes into play, being an attachment bond like that of a father with his newborn. And the people who develop an “anxious attachment” to their pets are precisely those who experience higher levels of anxiety when separating from them, as well as much more serious depressive and somatic symptoms when the animal dies or is not present. The solution. One of the important points in this case lies in teaching the dog’s brain that “exit signals” such as taking the keys or putting on the shoes, do not necessarily mean the end of the world, doing them without leaving the house. But also, we must keep in mind that when we return home we do not have to ‘throw a party’ to compensate for the guilt, since we only confirm to the dog that our absence was a terrible state of exception that has finally ended. This is why reunion should be normalized when we talk about a few hours of separation. Images | Wade Austin Ellis In Xataka | We have been using our pets to relieve our anxiety. And now the stress is on them

In its leap to electric cars, Europe fears total dependence on China. Your solutions arrive (quite) late

May 24, 2026 by usatoday24

The rope tightens. This time it is Europe that pulls to its side. Or, at least, that is what he wants according to what is stated in Financial Timeswhere we read that the European Union wants to force car manufacturers to reduce their level of dependence on China. Now, forcing them to buy fewer components from their suppliers. A new goal. It is, according to Financial Timeswhat the European Union wants to impose on companies in key sectors such as automobiles, industrial machinery or the chemical sector. In the newspaper’s information we read that European institutions are looking for tools to put pressure on their own companies. In the information, which is attributed to two European officials familiar with this project, the objective is to put a limit on the percentage of components that can be supplied to a single country. That is, if a company wants to manufacture a product in Europe, it could not buy all of its components (or the vast majority) from China. To distribute the purchases. If the project goes ahead as we read in the British media, a company could only buy between 30 and 40% of its components from the same country. It is sought that, at least, the origin of the parts that, in this case, make up a car is from three suppliers and from at least three different countries. This would not be much of a problem if it were not for the fact that the 30-40% barrier could not be overcome. “Gradually dependent”. “In many areas we are gradually becoming dependent on China’s exports,” the words are from a senior European Union official consulted by the newspaper. According to Financial Timesthe organizations are very aware of the extent to which a stoppage of Chinese factories or exports can damage the European economy. In fact, last summer some factories had to stop or saw their production compromised after China put greater impediments to export of products in which rare earths are used such as the magnets in electric car motors. Just a few months later, The Nexperia crisis once again set off the alarms of possible interruptions in the supply chain since a good part of the chips used by the European industry uses components from this company. They are not key products for its operation but without them, a car cannot be sold because They are essential for auxiliary but basic functions How to raise and lower the car window. 1 billion. That is what, according to Financial Timesthey calculate in the European Union that we lose to China. 1,000 million euros of deficit in the trade balance. 1,000 million. Diaries. The figure has been floating for two years now. and the automotive industry is one of those that has suffered the most. According to the European Union, they have achieved this with a doped industry, which has led to the lifting of tariffs on electric cars arriving from China. And the Chinese manufacturers have wanted to land abroad on our continent but also the Europeans have wanted to manufacture in China because it was cheaper. Spain? According to Anfac dataIn Spain we have a deficit in our trade balance of 5,000 million euros annually if we talk about components. As the second largest car producer in Europe, our auxiliary fabric is not enough and we need to buy components worth 16,893 million euros when exports exceed 11,525 million euros. There is no data on the origin of these imported components but we do know that The second country that exports the most cars to Spain is China. Last year, 9.2% of cars purchased in our country from outside our borders arrived from China. Very far, yes, from the German 26%. The problem is that despite importing cars worth almost 2.7 billion euros, China does not appear among the 10 countries to which we export the most cars and we barely place 658 million euros in exports to all of Asia. The game of balance. Yet the European Union is discovering that perhaps it has arrived late to the trade battle. Yes, it has lifted tariffs on electric cars sold from China but the country’s tentacles reach deep into vehicles made in Europe, producing all kinds of cheap components but also producing key technology such as semiconductors or batteries of electric cars. China is aware that it can squeeze European industry but it also needs our trade to export all the cars that are already surplus there. It is no coincidence that Europe has not imposed tariffs on cars arrived with combustion engines and? have negotiated with China the possibility of lifting trade barriers to electric cars. The Band-Aid. Until now, a very important part of the components used in European cars had their origin within the borders of the European Union itself. However, China’s weight has skyrocketed in recent years. In 2024, China has already become the main exporter of cars to Europe and the weight of its components within the cars manufactured here is increasingly greater, which reduces the competitiveness of our exports, according to this report BBVA. This imbalance is doubly worrying because the European Union is trying to reduce Chinese dependence now that it is seeking to make the definitive leap to the electric car, a technology where the Asian country dominates the supply chain. In recent months, Europe has tried to curb dependence promoting mineral mining on our soil or battery production but Chinese dependence remains evident.

Ozempic’s great challenge is the rebound effect. Science already has two promising solutions to avoid it

May 15, 2026 by usatoday24

The rise of medications such as Ozempic, wegovy o Mounjaru has completely transformed the clinical and social landscape of the weight lossmaking many people do not hesitate to ask their family doctor to prescribe it in order to lose weight and also regulate blood sugar. The results during treatment are undeniable, but the big question it raises about medical consultations is what exactly happens when the medication is stopped. What we know. One of the most feared points of this type of treatment is the ‘rebound effect’ which causes that, at the time of stopping the treatment and if eating habits have not been adjusted, a large weight gain will be seen. This is something that causes many people to see that this treatment only gives a few months of ‘thinness’, but science is now trying to avoid this effect. The rebound. An exhaustive analysis published in The BMJ finally put exact figures on this phenomenon so that you can speak appropriately to patients. And what has been seen after analyzing 9,300 participants is that patients recover an average of 0.4 kilos per month after stopping treatment. At this rate, the return to the initial weight before starting therapy occurs in just 1.7 years. But this is also accompanied by a loss of cardiovascular shield at 1.4 years. The solution. one of them it involves taking a pill daily known as orforglipronwhich is nothing more than a non-peptide GLP-1 receptor agonistwhich means that it can be taken orally and not through subcutaneous injections. The idea here is to use the injectable treatment, which is more powerful, for the first few weeks and then transition to this daily pill to consolidate the results without the rebound effect. This not only greatly improves patient comfort, but facilitates mass production by not relying on problematic ‘pens’ containing semaglutide, and helps maintain satiety signaling at the brain level without the invasive impact of the needle. A bacteria. The second line of research points to the intestinal microbiome, by analyzing supplementation with the bacteria Akkermansia muciniphila MucT pasteurized as a tool to avoid the rebound effect after a low-calorie diet. A bacteria that is long known in the field of nutrition for its role in the integrity of the intestinal barrier. After doing the analysisit was seen that the group of patients who received the bacterial supplement recorded a weight recovery of only 13.6%, compared to 32.9% in the control group. But beyond the scale, it has been seen that this bacteria shows a notable preservation of insulin sensitivity, a crucial factor to avoid the development of type 2 diabetes and keep lipid metabolism under control. The future. We are undoubtedly at the beginning of a paradigm shift, since the medical narrative is moving from the short-term “war against kilos” to chronic and sustainable management. But logically, for this to reach the market, we must wait (and not a little) for better results and above all for it to be tested in humans.

Southeast Spain is the driest place on the peninsula and a DANA has just arrived to “rescue” it. It will give more problems than solutions

March 10, 2026 by usatoday24

Right now, as I write, “the world cup is falling” on Alicante. And that, in itself, is news. Not the DANA that is crossing the southeast right now, which has a moderate entity and is going to leave unremarkable accumulations; No. It could be, but no. The news is thatit’s raining in the southeast and that, for some time now, has become almost a miracle. A miracle that leaves something revealed, Almería, Murcia and Alicante live in a climatic (and emotional) ‘new normal’ for which we have no physical (nor psychosocial) infrastructure. Let’s look at it in some detail. What is happening? At a meteorological level, the situation is very simple. In the early hours of March 10, a DANA detached itself from general circulation and positioned itself between eastern Andalusia and the Alboran Sea. In the next few hours, the epicenter It will be located over the province of Alicante and it will also cause enormous instability in Murcia, Albacete, all of eastern Andalusia and some parts of Valencia. AEMET predicts accumulations of between 30 and 50 mm in Murcia and Alicante, with some very specific areas reaching 80 in six hours. We may see snow above 900 meters. However, it must be taken into account that the DANA is very small: any change in trajectory, can move precipitation from one region to another. Is it normal? If we are honest, it is quite normal. This is part of a very unstable first week of March with storms, DANAs, haze and many more problems. The underlying problem. The problem is that, for months, we have seen how the very abundant rains of January They left aside this corner of the Peninsula. Thus, the Segura basin is the worst in the entire country followed by that of Júcar and that of the Andalusian Mediterranean basins. That is, not raining is a problem. But let it rain too. Because throughout that area of the country, although it may not seem like it, although it is very subtle, tension continues every time a DANA appears on the weather forecast maps. The worst part goes to the areas where it hit the DANA of 2024 (with up to 30% of children with sleep problems and thousands of people suffering from eco-anxiety and fear), but the consequences are there whether we like it or not. Above all, with failures around the corner. Rethink everything to adapt to what is coming. A few weeks ago, AEMET and the University of Valladolid They published a very interesting work in which they explained that without climate change the DANA of 2024 It would have been much more unlikely. The January rains over Andalusia they do not help to calm to the experts. Image | ECMWF In Xataka | In California, the funds discovered that there is no investment more profitable than farmland. Now it’s Spain’s turn

Something is going wrong with AI. The US is turning to energy solutions that it thought were buried to power data centers

December 25, 2025 by usatoday24

The race to develop and operate increasingly powerful artificial intelligence models comes at a cost that is rarely at the center of the technological narrative. It is not in the chips or the software, but in the huge amount of electricity needed to keep active data centers running around the clock. In the United States, this pressure is already being translated into concrete decisions: polluting power plants that were in retirement are being restarted to cover increasing peaks and tensions on the grid. The paradox is evident, the most ambitious advance in the technology sector depends, for the moment, on energy solutions from another era. The problem is not so much an absolute shortage of electricity as a time lag. The demand for data centers linked to AI it’s growing much faster than the ability to launch new electrical generation, especially renewable, in short terms. Building large energy infrastructures takes years, while these complexes can advance in much shorter time frames. Faced with this temporary shock, network operators and electricity companies are turning to what already exists and can be activated immediately, even if it is more polluting. PJM in context. The clash between electricity demand and supply is perceived with special clarity in the PJM region, the largest electricity market in the United States, which covers 13 states and concentrates a very significant part of the country’s data centers. We can understand it as a large regional electricity exchange that coordinates generation, prices and network stability in real time. There, the growth of data centers linked to AI is putting to the test a system designed for a very different consumption pattern, making PJM the first thermometer of a problem that is beginning to appear in other areas. What is a central peaker. The calls central peakeror peak, are facilities designed to come online only during short periods of peak demand, such as heat waves or winter peaks, when the system needs immediate reinforcement. They are not designed to operate continuously, but to react quickly. According to a report According to the US Government Accountability Office, these facilities generate just 3% of the country’s electricity, but they account for nearly 19% of the installed capacity, a reserve that is now being used much more frequently than expected. South view of the Fisk plant in Chicago The case of the Fisk plant, in the working-class neighborhood of Pilsen, in Chicago, illustrates well how this shift translates on the ground. It is an oil-fueled facility, built decades ago and scheduled to be retired next year, that had been relegated to an almost testimonial role. The arrival of new electrical demands associated with data centers changed that equation. Matt Pistner, senior vice president of generation at NRG Energy, explained to Reuters that the company saw an economic argument to maintain the units and that is why it withdrew the closure notice, a decision that returns activity to a location that many residents believed was in permanent withdrawal. When the price rules. The change is not explained only by technical needs, but also by very clear market signals. In PJM, the prices paid to generators to guarantee supply at times of maximum demand skyrocketed this summer, more than 800% compared to the previous year. An analysis by the aforementioned agency shows that about 60% of oil, gas and coal plants scheduled for retirement in the region postponed or canceled those plans this year, and most of them were units peakerjust the ones that best fit in this new scenario of relative scarcity. The bill for this energy shift is paid above all at a local level. The power plants peaker They tend to be older facilities, with lower chimneys and fewer pollution filters than other plants, which increases the impact on their immediate surroundings when they operate more frequently. Coal is also postponed. The phenomenon is not limited to power plants peaker fueled by oil or gas. On a national scale, several utilities have begun to delay the closure of coal plants that were part of their climate commitments. A DeSmog analysis identified at least 15 retirements postponed from January 2025 alone, facilities that together represent about 1.5% of US energy emissions. Dominion Energy offers a clear example: In 2020 he promised to generate all its electricity with renewables by 2045, but after the company projected that data center demand in Virginia will quadruple by 2038, it is now taking a step back.

Renfe trusted Talgo and his Avril trains to benefit from the particularities of Spain. Already look for solutions in Germany

September 1, 2025 by usatoday24

Spain is a particular country regarding the railway field. That is why the pair formed by Talgo and Renfe sounded especially good to compete with the new trains operators. Both companies could benefit and get a strategic advantage in the Galician corridor, while allowing him to fight in the rest of our country. The reality is that nothing has gone as expected. And now Spain looks for trains in Germany. “They have not given the best possible result”. This is how Óscar Puente, Minister of Transportation, has described the performance of the Talgo S-106 series that Renfe has had in operation. Words pick them up eldiario.eswho point out that Puente will go to a Siemens factory in Germany in search of solutions. The intention, everything indicates, is to reverse the bad results of the Spanish trains with an acquisition of Germans that allow Renfe to compete again on equal terms with Ouigo and Iroyo, who have found the open doors of high speed Low Cost In Madrid-Barcelona. “Corporate”. The bridge trip comes after Renfe will withdraw his Avlo trains from the Madrid-Barcelona corridor. The company’s official response is that AVE trains adapt better to a line in which a “corporate” client profile is better exploited. It is true that Half of the trips That Renfe was carrying out in this corridor made them with the AVE and that the Avlo market share was significantly lower than that of Ouigo and, above all, that of Iroyo. However, the real motive of its abandonment is that some Talgo trains of the S-106 series were being used. A crack. Metaphorical, if we talk about Renfe’s strategy. Material, if we talk about avlo trains. Those known as Avril, projected to compete with these two foreign companies in business volume, presented serious structural problems a few weeks ago. The company He took them out of circulation although at first He denied the problems. Finally, has taken out of circulation The Avlo service but there is no record of a trains relocation. That is, now ouigo and Iro will compete among them two for high speed at low price in that corridor. An oxygen ball for ouigo, which had retired some trains To show more battle in the Andalusian corridor. Recurring problems. As we pointed out, the bridge itself has already suggested that the operation of the aforementioned S-106 of Talgo has not been expected. The first ones that were launched in the Galician corridor and in the line with Asturias. In both cases they accumulated delays and breakdowns. Besides, Nor did they receive the best criticisms for its performance on the roads. Months later, the change of the year also affected the new cars of Talgo. A computer problem left them unused in the early hours of 2025causing important delays the first days. A few weeks ago the most serious fault occurred. Trains cracked (literally). The first solution was circular at a lower speed. The second, probably the most sensible, remove them from the line. Disappointing. The problem with Talgo’s S-106 series is even more disappointing if we take into account that it is a type of train that allows Renfe to Competitive advantage over Ouigo and Iro In the Galician corridor. Talgo is The only company that had built trains that could adapt to the different widths of our country. With compromised production, no one can buy more trains and, therefore, Renfe is in a monopolistic position in the short term. Therefore, perhaps, the disappointment is greater. Finally, trains that had to demonstrate the good Spanish doing in the railway sector have been working for Spanish roads and delays. But, above all, he has closed Renfe the doors of his great tool to compete against his rivals in a corridor where he dominates. Now, Spain will seek solutions in Germany.
