He returned his rental car and found an extra bill of $ 400. The reason: the AI ​​hunted a tiny scratch

During a trip, unforeseen events may arise. That is something relatively common, assumed and that must internalize anyone who considers making the bags to spend a few days away from home. Much less frequent is what happened to Patrick, a traveler who recently encountered a bill of More than 400 dollars When he returned his rental car at the Hertz branch of the International Airport Hartsfield-Jackson from Atlanta, in the US. The reason: A system with AI He analyzed the vehicle thoroughly and in just a few seconds he discovered that he had a scratch of several centimeters on a rear wheel. The story He has revealed it The Drive And more than one tourist who considers renting a car this vacation is probably removed. At least around Atlanta, in the US. Patrick recently, a client of Thriftya vehicle rental company linked to the international chain Hertz, found a surprise when he wanted to return the vehicle that had leased. Betrayed by algorithms The man did the usual one: he went to the company’s branch, delivered the vehicle (from the Volkswagen brand) and gave the procedure per setback. After a few minutes, however they told him that he had to pay a whopping $ 440. The reason? The company had identified a friction on the rear wheel on the driver’s side, a 2.5 cm scrape whose arrangement had to pay. Not just that. The company also broken down to him how he had calculated those $ 440. Of that amount almost half would be dedicated to repair. The rest corresponded to a series of expenses that made Patrick crawl the eyebrow. According to the company$ 125 responded to processing and 65 to administrative expenses. The man also found that the invoice came through a web application that contributed the damage test and allowed him to enjoy A small discountor as long as he paid at the same time. According to collect The Driveif it accepted the conditions and disbursed the money in 48 hours the company offered a bonus of 52 dollars. In case something else was delayed, but did not miss more than a week would be 32.5. The man chose not to pay. Moreover, when a few days ago He spoke with The Drive He had not yet paid the amount that the company claims for the wheel scrape. “Save 30 dollars to accept responsibility is not worth it,” says the driver, who after meeting the invoice first resorted to the Chatbot from Hertz (without too successful) and then sent an email to the company. So far the story is curious, but what makes the case of Patrick exceptional and has caught the media attention from other countries It is how the company detected the damage on the rear wheel of its Volkswagen. The merit was not of any operator or worker of the Branch of Atlanta International Airport especially diligent when examining the cars. No. The failure in the wheel was located by a New scanning system of cars that is based on AI. In April Hertz announced An alliance with Uveye, a firm specialized in the inspection of vehicles with AI, precisely to apply its technology in the US. “The camera systems with the Uveye and the algorithms of Machine Learning They allow automated inspections in real time of the body, the crystals, tires and low “, He claims Hertzwhich emphasizes that the new technology allows you to detect failures “with unprecedented speed and precision.” {“Videid”: “X91SZ26”, “Autoplay”: False, “Title”: “This is the perfect shipment of an airplane and no airline does it ❌✈️”, “Tag”: “Webedia-prod”, “Duration”: “567”} Already then The company advanced That the system would be released in Hartsfield-Jackson, although its objective is to expand it in not much time to the main US airfields. The company also claims that by “complementing” traditional exams with Uveye technology, it can guarantee its customers “more efficient and transparent reviews”, the latter nuance that He stressed These days a The Drive. The app that informed Patrick in fact included A photo of the scrape and another of the same part of the car just when he rented. The service, yes, does not seem free to leave. Hertz He explained That the so -called processing rate, which at least in the case of Patrick represents a sensitive part of the invoice, corresponds to “the cost of detecting and estimating damage during rent.” As for the administrative rate that includes the invoice, “it covers part of the costs incurred by Hertz by processing the claim.” Images | Uveye Via | Motorpasion In Xataka | Car rental: what is important to look before hiring (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news He returned his rental car and found an extra bill of $ 400.

Sam Altman states that Chatgpt’s water and energy consumption is tiny. The problem is that it does not give evidence of it

An email of 100 words generated by GPT-4 Consume 519 milliliters of water. That was the conclusion to which researchers at the University of California arrived a few months ago after analyzing this OpenAi model. Sam Altman, CEO of the company, has just yielded its own estimate on the consumption of water and energy of each consultation of Chatgpt. And it is very different. 1,000 times less than what was said. According to Altman, an average consultation in Chatgpt consumes much less than what had been indicated in previous studies. Your data are strikingand to understand them makes interesting analogies: “As production automated in data centers automates, the cost of intelligence should approach electricity. (People are usually curious to know how much energy consumes a chatgpt consultation; the average consult (0.32 ml); A previous study of Epoch ai corroborates the data that Sam Altman has now wielded. Source: Epoch AI. And the tests? Those figures mentioned by the OpenAi CEO have a problem: they have no visible support. He throws them without citing sources or explaining where he has taken them out, something that makes it difficult to believe. A Meta executive answered the question of How much consumes the inference AI A year and a half ago, responding that “only two nuclear reactors would be needed to cover it.” But previous studies coincide with Altman. Although he does not mention any evidence, in February, Epoch AI researchers precisely They published a study trying to estimate the energy consumption of chatgpt. In their conclusions they indicated that on average a chatgpt consult Previous report of the researcher Alex de Vries. Since then, of course, many things have happened. Too pessimistic. And as they commented on the study of Epoch AI, the difference comes from the fact that the models are today much more efficient than in 2023, when VRies conducted their study. So is the hardware in which these models are executed, and that estimate was also used a “especially pessimistic” approach. In Openai’s study they also threw an especially pessimistic estimate and pointed out that “most of the requests (A chatgpt) are much cheaper (energetically).” More studies. Another independent study published by Andy Masey in January 2025 reached a similar conclusion and claimed that “using Chatgpt is not bad for the environment.” It was based on EPRI data May 2024 that also estimated a high consumption of 2.9 Wh by chatgpt consultation. Estimated water consumption In data centersfrom A SUNBIRD studyit was also very modest compared to other online activities. Water consumption in data centers for various online activities. Source: Andy Masley. Fifte. Precisely the data of water consumption was another striking in that estimate of Sam Altman. According to him, a chatgpt consultation barely consumed 0.32 ml of water, “a quinceava part of a teaspoon.” The figure suggests that the water needed to refrigerate data centers that process these requests is much less than what was thought only one year ago. And training, what? These estimates focus on the AI ​​inference section, that is, our use of chatgpt that receives a consultation and processes it inferring (generating) a text result. Although Altman does not clarify it, he does not seem to include here the energy and water cost of training AI models, which is very high and makes thousands of Gpus They work at full power For months, with the consequent water expense in data centers to refrigerate all those components that dissipate high heat amounts. As I pointed out The researcher Ethan Mollick, GPT-4 probably used more than 50 GW to be trained, enough to give energy to 5,500 homes in a year. We continue without definitive data. Altman’s claims are as always striking, but the lack of clear evidence makes it difficult to believe these data. Other recent studies are more useful when it comes to reflecting this increasingly lower cost both in energy and water from the use of AI, but there are no accepted standards or a consensus on the true impact of energy and water consumption when using chatgpt or other AI models.

This strategic and tiny island has been disputed for 200 years. And the US and Canada still are not clear to whom it belongs to

The recent one Donald Trump’s insistence on Annexar Canada as the 51st state He has given for reflections in the American political sphere. While the idea does not seem taken seriously in Washington and the Canadian government has made it clear that it has no interest in joining the United States, The New York Times performed an electoral code analysis of such a scenario revealing an unexpected consequence: the incorporation of Canada would guarantee a political advantage for the Democratic Party in future elections. Be that as it may, the only certain thing in this whole story is the eternal dispute over an islet between both nations. An island and its importance. WE TALK ABOUT MACHIAS SEAL ISLANDa small islet of 18 hectares located at the point of confluence between the Bay of Fundy and the Gulf of Maine, which represents the last territorial dispute between Canada and the United States. Although its rock size and geography are little or rather liable, its strategic value and the wealth of its waters They have maintained the latent conflict for more than two centuries. A lighthouse as a symbol of sovereignty. The history of the dispute goes back to the war of 1812when both the United States and Great Britain claimed the island and its surrounding waters due to their location on an important navigation route. In 1832, Great Britain built a lighthouse on the island To consolidate its control, and since then, Canada has maintained a permanent presence in the place through Farros that, in addition to its maritime signaling work, act as symbolic guardians of Canadian sovereignty. In this regard, Russell and Anthony Ross, Farros brothers, turn every 28 days to keep the lighthouse in operation. Isolated on the island, their work goes beyond surveillance: they receive visitors who arrive in summer and, in winter, they support the extreme climate of the Atlantic without the possibility of returning to the continent until its allocation ends. For them, the island is more than a territory in dispute: it is their temporary home and a symbol of a tradition that few still keep alive. Frailecillos on the island A sanctuary for wildlife. Despite its uncertain geopolitical status, Machias Seal Island is recognized as a sanctuary of sea birds. The reason? Thousands of Atlantic Frailecillos, Common Mergles, Arctic Charranes and Common Alcas nest there every summer, making it a reference point for scientists and bird observers. In fact, the Canadian Wild Life Service protects access to the island, allowing only the arrival of two daily tourist boats, One from Maine and Another from New Brunswickwith a limited quota of visitors. Scientists like Tony Diamonddirector of Atlantic Laboratory for Avian Research, have studied these colonies since 1995, highlighting the importance of the island’s ecosystem as a thermometer of the state of the ocean. Tourism under surveillance. To avoid major evils, the experience of tourists is rigorously controlled. So much so, that to avoid damage to nests, They must remain in wood cattleway and use small observation structures camouflaged in the landscape. Although getting to the island is not easy, most of Visitors consider the effort to be worth itsince it is one of the few places where you can see these frailecillos in their natural environment without disturbances. The dispute: Waters of the gray zone. Beyond the small islet, the true conflict between Canada and the United States is not on earth, but rather in the sea. The waters around Machias Seal Island They are known as the “Gray Zone”an area of ​​approximately 700 square kilometers where both countries claim fishing rights. Moreover, in the last decades, The growing lobster demand has turned the area into a crucial economic resource. The price of crustacean has tripled, reaching values ​​of up to 4 Canadian dollars for 400 grams, which has promoted the prosperity of fishing communities Like Grand Manan, in Canada. Live in the conflict. For many fishermen, The gray zone represents a constant income opportunityand although there are no formal agreements, they have developed a coexistence system based on mutual respect. Of course, not everything is harmony. As the lobster demand has continued to increase, The pressure on marine resources is increasing. Sector veterans warn that The overfishing could exhaust the lobster populationfollowing the same collapse pattern that affected the herring industry, background fish and scallops in the past. Uncertain future. Be that as it may, and despite the territorial dispute, so far Canada and the United States have avoided an open conflict about Machias Seal Island and the gray areamaintaining that fragile balance between the symbolic presence of Canada on the island and the joint fishing exploitation in its waters. Yet, The recent political and commercial tensions between the two countries They have generated uncertainty about the future of this enclave. In that sense, Trump’s latest statements have not helped. The inhabitants of the island, whether beareros, scientists or fishermen, continue with their lives at the same time that international policy follows its course. While the frailecillos continue to nest in the cliffs and lobster ships they slaughter in the gray area, the islet is maintained as a tiny point on the map, although not any one: one with a geopolitical, economic and ecological influence much larger than its size suggests. .Imagen | Melissa McMasters, Melissa McMasters In Xataka | The longest dispute is a 500 -year -old mystery.

The new hope against Alzheimer’s is a simple protein. We have discovered it thanks to a tiny worm

Many of the processes that happen in our body depend on proteins. All if we take into account the processes that do it indirectly. Sometimes proteins fail. Then, the function of cleaning these “defective” proteins falls, yes, on other proteins. MANF. A new study He has revealed The importance of MANF protein (Mesencephalic Astrocyte-Derned Neurotrophic Factor) For our aging or, to be more precise, when avoiding some of the problems that arise at the cellular level and that we usually associate with age. Doing cleaning. In principle, that a cell badly codifies a protein does not have to generate major problems in our body. Cell homeostasis, the process that discards proteins after use, is a cellular “maintenance” process that deals with this type of problem. However, with age our cells lose efficacy when keeping the house in order. “Defective” proteins can end up accumulating and generating protein clots. This is What we believe occurs with diseases such as Parkinson or Alzheimer’s. When the cell detects these problems, it can stop synthesizing new proteins until the problem is solved. If it does not, the cell dies. Cleaning work. The new study has observed that MANF protein It plays an important role in this cleaning process inside the cell. His work consists in breaking protein clusters to facilitate the expulsion of these and thus maintaining our healthy cells. The team observed that this protein also served to “activate” the intracellular cleaning system. C. Elegans. In his work, the team turned to a unique worm, the Caenorhabditis Elegansa usual microscopic size nematode in laboratories around the world. The team altered the genetics of these worms to increase the presence of the MANF protein in their cells. The worms C. Elegans They are transparent, which facilitates the work of researchers when visualizing the changes that induce their genes. The team managed to see the effects of MANF on cells and tissues. Protein, They pointwas present in the lysosomas (some cell organelles linked to longevity and protein aggregation). In this way they could appreciate how the protein broke cell clusters and activated the cleaning system. The details of the experiment were published In an article In the magazine Proceedings of the National Academy of Sciences. Beyond worms. What is true for the biology of a small worm does not have to be in that of humans, but the team points out that this would be a universal process, at least in animal cells since Manf is a common protein to all species of this kingdom. The fight against Alzheimer’s. The big issue is now how to transform this new knowledge into therapies to fight some of the diseases that we associate with aging, such as Alzheimer’s, or against aging itself. Alzheimer is an important since the dominant hypothesis to explain this disease part precisely of the appearance of intracellular clusters such as those that fight the Manf protein. As explained by those responsible for the new study, transforming this protein into a treatment will require better understanding its role in our body and other possible interactions between it and cellular functions beyond cell homeostasis.
