The heat is uncovering one of the biggest problems with smart rings

A quarter of a century ago (seriously), Sonia and Selena sang that “When the heat comes, the boys fall in love.” Today we can add one more phrase to the song: your hands swell and, if you are wearing a ring, forget to take it out. If it is also a smart ring, with its sensors and lithium battery, we have a problem. This is what many users are discovering. This is tight. If it is hot and we also start exercising, it is quite common for a small swelling to occur in the hands. That’s exactly what happened to him to this journalist when he went out for a route through the forest: shortly after starting, he felt how the ring began to tighten more than necessary and he had to take it off. In the case of a watch or bracelet there is no problem because we can loosen it, but the rings are completely rigid devices, often made of metal, and with a thicker design than a conventional ring so they end up being more annoying. The effects of heat. When the temperature begins to rise, blood vessels dilate to release heat, causing more fluid to leak into the tissues. The areas where it usually ends up accumulating are hands and feet due to the effect of gravity. It is what is known as heat edema and it is quite common in the summer months or when we exercise. Not only do the fingers swell. The battery can also expand due to a defect or heat itself, making the ring feel smaller. This Oura Ring user He noticed that as time went by his ring felt tighter and the battery also lasted much less. When he contacted the brand, they confirmed that it was a battery problem and they ended up changing the device. There is more similar cases on Reddit. Miss a plane. The case of youtuber Daniel Rotar It is perhaps the most striking of all. The battery in his Galaxy Ring began to swell causing the ring to get completely stuck on his finger. It hurt and there was no way to get it off, not even with soap and water. As if that were not enough, Daniel was about to take a flight, but was denied boarding because the ring’s battery posed a security risk. He ended up missing his flight and had to go to the emergency room to have the ring removed using ice and lubricant. What companies say. Samsung has a help page with tips on how to remove a Galaxy Ring in case it gets stuck on your finger. They suggest using soap and water, dipping your hand in cold water, or holding your hand up high. If none of this works, they recommend going to the emergency room and having them cut the ring, even indicating the points where to cut so as not to damage the battery and which could end up causing burns. In the case of Oura They also offer the same advice and a guide to know where to cut if necessary. Rethink the design. Smart rings are sold as the solution to monitor our health with an ultra-compact design and more comfortable than a watch, until it gets stuck and you have to cut it off, of course. In this sense, perhaps the future of this product involves sacrificing that rigid and continuous aesthetic, giving way to open designs that can better adapt to these natural changes in the body. It is a path that the company has already started Movano with the Evie ring. Image | Xataka In Xataka | Best smart rings 2026. Which one to buy based on use and six recommended models

The trial against Sam Altman seemed like a duel between two millionaires. It has ended up uncovering the ins and outs of OpenAI

Three weeks of testimonies, 78 messages between Sam Altman and Mira Murati during the night they were going to kill him as CEOemails where Greg Brockman wrote in his personal diary how nice it would be to “earn billions” and Satya Nadella describing the OpenAI board as ““amateur city”. This Thursday the final arguments of the Musk vs. Altman trial were held in a federal court in Oakland. The lawsuit asked for 150,000 million in damages and the dismissal of Altman. What has been left for the public has not so much to do with the verdict. Why is it important. OpenAI is, despite its name, one of the most secretive companies in Silicon Valley. Its internal functioning, until now, was known through highly selected profiles in The New Yorker or specific leaks. The trial has forced the company to publish emails, text messages, personal diaries and depositions that depict an organization very different from the one that sells its official communication. A company plagued by power struggles, mutual suspicions between founders and a board that in 2023 could not explain why it fired its own CEO. behind the scenes. The most illuminating episode occurred not on the stand, but in a chain of late-night messages between Altman and Murati during “The Blip“, the weekend of November 2023 in which the board removed the CEO. At 2:30 a.m. Monday morning, Altman was asking his then-CTO if things were going well or badly. “This is going in a very bad direction. Sam, this is very serious,” Murati responded. Minutes later, Altman offered to leave to avoid lawsuits. Murati replied that the council already had a replacement: “uncle random of Twitch”, in reference to Emmett Shear. That same day, Murati signed the first of the letters from employees asking for Altman’s return. The contrast. What Murati’s deposition leaked is that she herself had fed the board with complaints about Altman before the firing. Helen Toner, a former councillor, testified that Murati and co-founder Ilya Sutskever had conveyed to the council a pattern of behavior about Altman’s honesty. Sutskever wrote a 52-page memorandum. On the stand, Sutskever himself confirmed writing to the board that Altman “demonstrates a consistent pattern of lying, undermining his executives, and pitting them against each other.” Murati, in his deposition, maintained his criticisms but framed them as “purely managerial.” Go deeper. The term that the Microsoft leadership used to describe what they saw in those days was said by Satya Nadella from the stand: ‘amateur city. The CEO of Microsoft, the main investor in OpenAI with more than 13 billion contributed, said that he never received a concrete explanation of why Altman was fired. “I was very concerned that employees would leave en masse,” he said. Nadella offered Altman a position at Microsoft with an open invitation to the entire OpenAI team. Altman admitted at trial that he was on the verge of accepting: “I would have made a lot of money and had a much easier life at Microsoft.” He ended up coming back to OpenAI with some new advice. The outgoing board’s accusation was that Altman “had not been consistently candid” with them. The money trail. The trial has also exposed Altman’s web of personal interests in companies that do business with OpenAI. While under interrogation, Altman acknowledged stakes worth more than $2 billion in companies such as Helion Energy, Cerebras –just went public–, Reddit or Stripe. His third of Helion (from which he has just left as president) is valued at 1,650 million. OpenAI has signed a framework agreement with Helion for future energy supplies. Forbes has recalculated his assets at more than 4,000 million after these revelations. Brockman, who according to Musk “did not invest a cent”, now appears with a stake valued at 30 billion. Yes, but. None of this changes the legal background. The jury must decide on two specific civil claims: breach of fiduciary trust and unjust enrichment. Musk’s lawyer, Steven Molo, has tried to turn this into a trial about Altman’s credibility. In his closing arguments he put an unflattering photo of the CEO on screen and asked the jury to imagine a bridge over a ravine “built on Sam Altman’s version of the truth.” And now what. OpenAI has been preparing for a long time an IPO that could value it at close to a billion dollars. Musk, meanwhile, flew to China with Trump despite the judicial warning that he could be called to testify again. Regardless of the ruling, the reputational damage has already been done. The narrative that OpenAI has tried to project for years (that of being an idealistic laboratory guided by the mission of benefiting humanity) now coexists with another version documented in a judicial process: that of a company where the co-founder sends messages to the CEO at two in the morning to tell him that it is finished and a few hours later she signs the letter asking for her return. A company where the president wrote in his diary that “it would be nice to earn billions.” And where the reference investor, seeing the chaos from the outside, called ‘amateur city to its governing bodies. The jury’s verdict will come next week. What can no longer be archived are the documents.

Mercedes broke out for uncovering the anti -petitive pact

The European Commission has imposed A sanction of 458 million euros to 15 car manufacturers for its involvement in an illegal pact on recycling. Paradoxically, the scandal was uncovered thanks to Mercedes-Benz, who participated in the framework, but when exposing him to European regulators he obtained total immunity. A pact not to compete. According to the commissionthe manufacturers involved agreed two key practices. On the one hand, not paying vehicle dismantlers, starting from the idea that recycling was a profitable enough business to not have to remunerate it. They did it under a strategy that they baptized as “zero treatment cost.” On the other, they agreed not to make public data on the percentage of recyclability of their vehicles or on the amount of recycled materials used in the manufacture of new cars. The objective was to prevent this information from generating competitive pressure between brands or expectations among consumers. The infraction. These practices went against the Directive 2000/53/CE On vehicles out of use, which establishes that the last owner must be able to deliver his car to a drain without any cost. If necessary, it is the manufacturers themselves who must assume that expense, in addition to adequately informing the recycling and reuse data. The detail of the fines imposed by the EU. The highest sanction has been for Volkswagen, with 127.7 million euros. They are followed by Renault/Nissan with 81 million, and Stellantis with almost 75 million. Toyota, BMW, Ford, Hyundai, GM, Suzuki, Mazda and Volvo also appear on the list, with amounts ranging between 1 and 25 million euros. The ACEA (European Association of Automobile Manufacturers) has also been sanctioned, in this case with a fine of 500,000 euros. The investigation concluded that it acted as a facilitator of the Pact, having organized numerous meetings and coordinated contacts between the manufacturers involved. Mercedes-Benz is fought from fines. Although he participated in the illegal agreement, Mercedes-Benz has not been fined. It was the company that went to the commission in 2019 and activated the clemency program, revealing the existence of the cartel and providing key evidence. If he had not done it, he would have faced a penalty of 35 million euros. Stellantis, Mitsubishi and Ford also subsequently collaborated, which allowed them to obtain reductions in their fines under the same procedure. A pact that crossed borders. The European Commission did not act alone. The investigation was coordinated with the United Kingdom competence authority (CMA), which announced additional sanctions for more than 77 million pounds (about 92 million euros). Among those fined by the British competence authority are Ford and Volkswagen. Challenging times. The news does not arrive at the best time for the sector. The European car industry is under pressure, partly because of the accelerated growth of the sector in China, which threatens to change the global balance. To that are added commercial tensions with the United States, which recently announced new vehicle import tariffs. In the words of Teresa Ribera. The Spanish Commissioner who leads the competition efforts in the European Commission has left a forceful statement: “Today we have taken energetic measures against the companies that were conspired to prevent competition in recycling.” Along these lines, he pointed out that they will not tolerate this type of practices.
