This is how the new carbon-based nuclear batteries work-14

by

No, you are not having a dejà vu. Nuclear batteries They were on everyone’s lipsafter the Chinese company Betavolt announced the beginning of the production of its batteries. And although it seems a new idea, the first nuclear battery was created in 1954 using Strontium-90. Since then, the search for safer batteries has continued and South Korea has given a new impulse. Short. A group of scientists from the Daegu Gyeongbuk Institute and Technology has developed A nuclear battery that promises to convert radiation into electricity for decades, without the characteristic dangers of conventional nuclear energy. According to Newatlasthe betavoltaic cell sensitized with dye uses beta particles to generate electricity from carbon-14. There is battery for a while. Carbon-14, with a half-life of 5730 years, will guarantee a long-term energy supply, at least in theory. However, in practice, factors such as material degradation and progressive loss of efficiency can limit the real battery life. It is just a prototype. As They have detailed In Newatlas, the battery has a relatively low power density – 20.75 nanovatos per square centimeter by milicur, with an efficiency of 2.86 % -, and the progress opens the door to applications where longevity is crucial. Instead of depending on lithium -ion batteries, very low consumption devices could use this technology and eliminate the need for frequent recharges or substitutions. More technical. The operation of this battery is based on the emission of beta particles from carbon-14, a radioactive isotope that emits high energy electrons. These electrons impact on a titanium dioxide semiconductor covered with a ruthenium -based dye, which causes the flow of electric current. Do you have real application? Scientists They have done An estimate considering sectors where longevity and low energy consumption are key. On the one hand, in the medical field, to feed implantable devices, such as pacemakers and sensors. On the other hand, in remote or difficult access for environmental monitoring stations, allowing continuous functioning for years without human intervention. Also, researchers have observed that integration in microchips, RFID labels and other miniaturized devices, as well as slow load applications, where small capacitors could accumulate energy and free it quickly in demand peaks, would be interesting. Something already existed … At the University of Bristol They have designed A carbon-14-based nuclear battery, but the approaches are different. In the British version, carbon-14 is encapsulated in synthetic diamond, offering extreme durability of up to 5,700 years and greater protection against radiation. The latter, although more expensive and complex to manufacture, is oriented to devices that require continuous operation for centuries, such as space probes or monitoring systems in extreme environments, while the Korean option could be more viable for low -cost applications and lower energy demand. Chinese technology vs Korean. Both technologies, the nuclear battery developed in South Korea and BV100 of betavolt From China, they share the principle of converting radioactive energy into electricity, but they diverge significantly in their approaches and applications. The Chinese battery uses Nickel-63, an isotope with a half-life of 100 years, in a more compact and modular design that promises to feed higher power devices, including drones and industrial equipment. In addition, while the Korean battery is still in an experimental phase, Betavolt has advanced towards marketing. Forecasts. While there is still a way to go to perfect its efficiency and reduce costs, the perspective of batteries that can last decades without recharges completely redefine the way we conceive energy storage and open new possibilities.

Airbnb does not want to be just the place where you reserve the floor of your vacation. Now you want to look for chef and coach

by

Airbnb no longer wants to be (alone) the place you go to search and book the house where you will spend your next vacation. That, He assured Tuesday His co -founder and CEO, Brian Chesky, has fallen short. With the tourism market upthe recent memory of pandemic and regulatory challenge every time More presentAirbnb has decided to undergo one of the biggest changes he has lived in its 18 years of history. Its objective: to be a comprehensive tourist platform. And that happens to facilitate the search for accommodation, but also offer Hairdressers, chefs, masseuses, or even a plan to learn flamenco in Madrid or riding a horse in Cuzco. Everything you need for your trip. “Much more than Airbnb”. The phrase is from Chesky and although it could perfectly go through a commercial slogan, it captures well the essence of the change that the company wanted to apply to the summer doors of 2025. After 18 years of travel, Millions of active ads And more than 2,000 million registered stays, Airbnb has decided to undergo an image change and expand its scope. His idea is very simple: he no longer wants to limit himself to accommodation management. Now the app will also allow to hire services and experiences. Do you want a personal coach? You have it. Do you want to resort to the services of a chef, a masseuse or an original experience, such as a gastronomic route, a horse ride or shopping with a stylist? You have it too. Airbnb’s goal is to make the leap to services and complete the experience of tourists. Why’s that? The company assures who wants to stand up to his main competitor: the hotels. “Often people decide Explain. The truth is that its new business turn arrives in a stage marked by other factors, not only the competition that accommodations can exercise. Challenges on the horizon. After almost 20 years of accelerated expansion and add millions of offers in much of the planet (in 2024 Statista spoke Of almost eight million advertisements in 100,000 cities), Airbnb has seen how its regulatory scenario has been complicated. In New York They have put limitsin Norway it applies A ratein cities like Madrid or Florence Its expansion has been stopped by Moratory and restrictions on the opening of new tourist floors and in Barcelona directly wants to end With them. And that to quote just some examples of territories that have moved to paliar tab The impact of the sector in its residential market. The company has also suffered A fall In the stock market Regarding 2024 before business and BBC precise That, despite the strength of his latest profits, Airbnb has warned that the increase in reserves could slow down this quarter. Two ideas: services and experiences. Airbnb has decided to articulate its new offer around those two groups: services and experiences. The first has in turn divided it into 10 categories among which are chefs that prepare food at home, photographers, masseuses, coaches, hairdressers or catering. Airbnb says that it has “evaluated the knowledge and reputation” of all its “hosts” and guarantees that they have an average of ten years of experience, have contributed the necessary permits and also verified their identity. “Best of all, it is not necessary assures. Regarding prices, options are included for less than 50 euros. Airbnb presumes in addition to having recognized professionals (chefs with Michelin stars) and offers that can only be hired through the platform itself. Go out of route or go shops. The other leg of the new Airbnb offer are the “experiences”, available a priori in several hundred cities. As an example the company quotes A route For the Parisian heritage with an architect who has documented the reconstruction of Notre-Dame, Kitchen classes With a Japanese chef, excursions on horseback by Inca sacred places with an anthropologist or a Fight class in a Mexican ring with a professional fighter. Again, Airbnb presumes that part of those experiences are “Airbnb Originals”. And how do you intend to do it? Airbnb Clarify That the services will start in 260 cities with a dozen different categories, “although new types of offers and additional locations will appear in the app every so often,” he says. As for the experiences, they will be launched in more than 650 cities in the world. The country Precise that services and experiences will be available in destinations such as Barcelona, ​​Madrid, Malaga or Seville. For example, flamenco classes are included, a visit to the meadow, wines and oils or tapas routes. To articulate the new Airbnb offer, it has also decided to “totally renew” its app to facilitate that it becomes a comprehensive travel platform: a tool with which to reserve stay, services and plans. “When users reserve accommodation, the application will suggest services and experiences depending on where they are going to stay and who will accompany them,” Clarify. The change comes more than two years later that Chesky proposed to transform the company and an investment that would be around 250 million dollars.

Some Tesla employees requested Elon Musk’s dismissal in a public letter. The company responded with fulminating dismissals

by

In recent months the situation of Tesla It has been complicated for a series of catastrophic misfortunes. Some of them were predictable, such as the punctual fall in sales before The renewal of its supervent model, the Model and. Others, on the other hand, have been entirely unexpected. As the reputational crisis that has collapsed the sales of the brand’s cars worldwide by the Elon Musk’s political implication and his role Doge front. The Tesla crisis not only manifested outside doors. The Sales fall And the growing discontent among employees have triggered an internal crisis between the template unprecedentedputting Elon Musk in the center of the hurricane. Employees They claimed Elon Musk’s departure of the company’s management. That petition has resulted in dismissals, but not that of his CEO. An unsustainable situation even for the template The internal tension reached its peak when a group of Employees from Tesla, both current and old, decided to publicly express their discontent with the management of the company. They did it through an open letter Published on the Web “Tesla Employees Against Elon”. In the publication, employees and small shareholders who had been part of the Tesla staff directly requested the departure of Elon Musk as the company’s CEO. “We are at a crossroads: continue with Elon as CEO of Tesla and face a greater decline as customers leave the brand, or advance without it and allow our products and mission to succeed or fail for themselves,” he explained in the workers’ statement. The signatories They pointed out that the damage Musk’s personal brand is “irreversible” and that his figure as the maximum representative of Tesla has become In a load for the entire template. Employees reproach their main manager His intention to “rename” In the Tesla direction, and they consider it “insulting” for being an explicit recognition that Tesla’s problems are the result of its neglect of functions at the head of the company. “Let’s be clear: we are not the problem. Our products are not the problem. Our engineering, service and delivery teams are not the problem. The problem is demand. The problem is Elon,” said the statement. More electric, but less Tesla While the electric vehicle market grows at a good pace, Tesla’s sale figures do not give signs of recovery. In Spain, the brand already registers falls of more than 16% and none of Tesla’s models appears among the 10 best -selling electric cars In Spain. According to data April of the Spanish Association of Automobile and Truck Manufacturers (ANFAC) The electrified tourism market grew 79% last month, which represents a 6.5% sales increase with respect to the same period last year. The phenomenon is not limited to Spain. Reuters echoed the latest data from the global electric vehicle market, which in April had grown by 29% year -on -year, despite uncertainty for tariffs imposed by the US. The US electric car market also records upward values. The data of Cox Automotive indicate a Growth of 18.5% In the volume of new electric car sales month by month, while the Tesla market share fell five points to 42%. The data announced in its presentation of Results of the first 2025 quartercorroborated this downward trend. The manufacturer delivered 336,681 vehicles, which represented a 13% drop with respect to the same period of the previous year, when almost 387,000 units had been delivered. As the employees pointed out in their open letter, “this is not due to the fact that our cars have worsened. It is not due to affordability problems. But to the fact that people no longer want to associate with Elon. Production marches better than ever. Quality is high. Processes are solid. Demand is what fails. It is not a product problem. It is a Leadership problem“ Tesla’s response: layoffs Tesla’s address to the publication of the letter was immediate and forceful. According to published Business Insiderseveral critical employees with Musk They were fulminating. This manufacturer’s reaction has generated even more Fear and self -censorship Within the company, reviving accusations of repression and contradiction with speech “Absolutist of Freedom of Expression“That Musk itself defends publicly. One of the most prominent cases is that of Matthew Labrot, former responsibility of Sales and Delivery Training of Tesla, and one of the main drivers of the protest. Labrot declared in Business Insider Being a passionate defender of Tesla, but was fired in less than 24 hours after the open letter on the website and participating in the protest under the motto “Pro Tesla, Not Elon!”, whose Account in x It has been suspended. Despite having lost his job in Tesla, Labrot says that “I still believe firmly in the company and in the objective we pursue”, but maintains its critical position with the Musk’s negative influence in the company and in its public image.

We have just found new tests of Ozempic’s benefits in another field: dementia

by

Although drugs pass exhaustive controls dedicated to, among other things, detect side effects, their clinical use allows us to find out new details about their effects on the body. This includes associated risks, but also possible additional benefits we did not count on. Lower risk of dementia. Drugs destined to keep blood sugar levels under control in people with diabetes (such as Ozempic or Zepbound) They can have a positive effectreducing our risk of dementia. Several studies have deepened in this relationship, offering hopeful results in this regard. Diabetes and dementia. Diabetes is one of the Risk factors that we usually associate with the appearance of dementia, such as age, tobacco, certain genetic factors or cholesterol, among others. Diabetes It is also a risk factor in arterosclerosis and stroke or stroke, which are factors that also contribute to certain forms of dementia. Knowing this, it can be intuitive to think that drugs that help us keep diabetes at bay can have this type of effects. However, intuition is not enough, so several research groups take time to work to better understand the underlying interactions and be able to strengthen our knowledge about the issue. Two studies. A few weeks ago, the magazine Jama Neurology He published two independent studies on each other who tried to investigate this issue. Both focused on how drugs aimed at reducing the amount of blood sugar were associated with a lower risk of dementia and cognitive problems among people with type 2 diabetes. Reviewing the evidence. One of the studies It was based on the systematic review of scientific literature related to the subject, review accompanied by a meta -analysis, a quantitative study of the results compiled through the review. This analysis was carried out from 26 randomized essays among which were added about 165,000 participants. The team responsible for the study did not find a significant change in the risk of dementia when studying the set of treatments focused on glucose reduction. But he did find that agonists of the peptide receptors similar to type 1 glucagon (LPG-1), the family of compounds to which the semaglutida belongs and therefore Ozempic, were related to a risk of suffering from 45% lower. One more essay. The second of the studies mentioned focused on two drugs, the agonostas of the GLP-1 receptors (LPG-1st) and the sodium/glucose collection inhibitors 2 (SGLT2is). The team observed that both the LPG-1ras and the SGLT2is were linked to a lower risk of suffering some forms of dementia such as Alzheimer’s in contrast to other treatments destined for glycemic control. A key factor. Studying the link between diabetes and dementia can open the way to better understand a disorder as complex as dementia. There is still little that we know about cognitive deterioration associated with age and disorders such as Alzheimer’s, but in increasingly aging societies, finding ways to reduce their weight in the well -being of older people will become unavoidable.

NASA engineers have repaired in extremis lost engines 20 years ago

by

When we thought we had seen everything from Voyager 1, NASA surprises us with a new feat. The venerable space probe, which has been moving away from the earth almost half a century, has recovered engines that were considered lost since 2024; A crucial repair that arrives just in time. Miracle? Nothing of the sort. It has been a mixture of ingenuity and risk that allowed NASA engineers Jet Propulsion Laboratory (JPL) Not only promises to exhaust the useful life of the probe, but was made just before the only land antenna capable of sending commands to enter a long maintenance period. Context. The Voyager 1 probe, launched in 1977 with its twin Voyager 2, is located in the interstellar space, about 25,000 million kilometers from the earth. Traveling almost 56,000 kilometers per hour, to keep your main antenna pointing towards us and being able to send us your data, the ship needs to make subtle orientation settings. These movements, remember Paraspacial procesthey are of three types: nod (up and down), wink (left and right) and praise. The latter, the “roll” movement, turns the ship on its axis, and is essential to keep a guide star that Voyager uses to orient and calibrates its magnetometer. They threw the towel. The main propellers of Alabeo de la Voyager 1 stopped working in 2004 for the loss of energy of two small internal heater. Without heater, the fuel of the propellers (hydrazine) is freezing and can cause an explosion in the ship’s nozzle. At that time, NASA engineers concluded that the ruling was irreparable and decided to move on to the reserve praise, they have been working to guide the ship since then. “They probably did not think that the Voyager would continue to run another 20 years,” Kareem Badaruddin, leader of the Voyager Mission in the JPL, said in a statement. 20 years later. The ducts of the reserve propensors are beginning to obstruct due to hydraction residues. According to NASA estimates, they could be completely blocked this autumn, which would make Voyager 1 lose the ability to control alabeo, making the mission seriously danger. Given this perspective, the Voyager team began a career to counter to reexamine the 2004 ruling. The suspicion was that a disturbance in the circuits that control the energy supply of the heater had “moved a switch” to the incorrect position. If they could return that switch to their original state, perhaps the heaters would work again and, with them, the alabus thrusters. A doubly risky plan. It involved lighting the inactive propellants and then trying to fix and restart the heaters. If during this process, the ship’s tracker was too diverted from its guide star, the inactive propellers would firing automatically. And if the heaters were still turned off at that time, an explosion could have occurred. To top it off, NASA only had a margin until May 4 for a scheduled maintenance of antenna 43 of the deep space network. The 70 -meter antenna, located at the Cambberra station, is the only take a whole day to arrive and another to returnthey played to counterreloj. Success. In spite of everything, the team sent the necessary commands on March 18. March 20, They received telemetry with the results. For relief and euphoria of the team, at 20 minutes of starting to receive the data, the temperature of the heater increased drastically. The plan had worked. With this repair, the mission team breathes calmer. If current alabeous propellants are obstructed in the coming months, Voyager 1 may be changed without problems to these newly reactivated propellers and continue working normally.

Aragon wanted his children to eat more fruit at school. So he went to look for her 10,000 kilometers away

by

The Aragonese political debate has waited these days with two unexpected protagonists: fruit and schools. Or rather, the fruit that is distributed in schools. Although Aragon has thousands and thousands of hectares full of fruit and vegetable trees and stands out in the production Of cherry, peach and apples, among other fruits, the farmers of the region have raised their voice to complain that in the educational centers of their villages, pieces that arrive from plantations located abroad are being distributed, in some cases thousands of kilometers. The complaint the has launched the union of farmers and ranchers of Aragon (UAGA) and puts the finger in a yaga that already has taken to the collective To the street. What happened? The complaint has been made public UAGA-COAG. In A statement Published yesterday the Agrarian Organization ensures that there are dining rooms of educational centers in Aragon in which fruit arrives from foreign countries is being distributed. Moreover, UAGA goes further and claims to have witnesses confirming that in several schools in the region oranges from Egypt and pears of South Africa have been delivered, cultivated to more than 10,000 kilometers of distance. As a test, the association includes a photograph in which a box of pears is shown that indicates that its origin is South Africa, although there is no reference that reveals that the image was taken in a Aragon school. Click on the image to go to Tweet. “Unfair competition”. In its statement UAGA claims to feel “outraged” by the importation of fruits that it is perfectly possible to find in the Spanish fields and questions that countries from which the merchandise is brought meet the sanitary, environmental and labor standards that the European Union does require that community farmers. “It involves the violation of the demands of the organization and the fruit growers that require the application of ‘mirror clauses’ to imports from third countries “, They emphasize From the collective. UAGA-COAG wields two reasons that, in their opinion, condemn local farmers to suffer “unfair competition” against imports from other countries. The first is the strict regulation imposed by Brussels to European plantations on the use of pesticides, manipulation and conservation of fruit. The second is labor costs. While in Spain they go up every year, in Egypt, complaintthe minimum wage is 176 euros per month and in South Africa it is around 270. Looking at the EU. The complaint of the UAGA has reached enough draft for the Aragon Government to have gone to give explanations. The regional press appointment Sources of the Ministry of Agriculture that clarify that the key is in the financing of the lunch and sowing program to schools: the funds start from the EU, with what they arrive accompanied by their standards. When hiring the fruit supply, a geographical proximity requirement is not applied nor is it requested that the products be of community origin precisely to avoid a “discriminatory competitive advantage” in the process. The regional government argues that its role is that of intermediary. And now what? The Regional Executive emphasize Also that the objective is to “consolidate healthy eating habits” among schoolchildren and that fruit and milk are distributed at times such as lunch and snack, not in dining services. The program is not exactly new, but now it is offered with mixed funds that combine a community contribution and another from Aragon. With the EU money, a lot of 300,000 euros that is managed with the requirements of Brussels is paid. With the one contributed by the Aragon government, another 200,000 is financed that can handle with its own criteria. And the administration already guarantees that, “in line with its defense of the local product,” will give priority to proximity productions. The idea is to distribute cherries, apricot and nectarines, although they can also be replaced by apples or pears if requested by the centers. Beyond schools. The fruit distribution program is important because it reaches hundreds of school points and thousands of children, but the “outrage” of Uaga-Coag is not explained only by the alleged distribution of pears of South Africa and oranges of Egypt instead of fruit grown in the Aragonese countryside. Farmers It has come out To the street On several occasions to claim decent prices, changes in community policy and greater controls to ensure that the merchandise that comes to the country conforms to the community demands with which they work. “These parameters make it possible to import fruit from third countries profitable for certain companies and generate unfair competition at all levels,” the Agrarian Association in Your statement. “To end these practices, UAGA insists on claiming public administrations (regional, state and European) the regulation of markets and the recovery of the principle of community preference.” Images | Federicoeth Photography (Flickr) and Uaga In Xataka | We have a hard time differentiating a banana from a banana.

For the first time in history, we have a small way to try

by

In the 2000s, some researchers from the University of California in San Francisco realized that it was true that there were people who needed to sleep less than normal. That is, people who, naturally, sleep between three and six hours (and do not present symptoms of fatigue or cognitive impairment). AND It could not beclear. The consensus among the specialists is that all those people who said to sleep little or did not have a good perception of the time they slept or they were making cognitive damage of which they were not aware. They began to investigate it. Sik3-N783Y. 20 years have taken, but that summarizes the conclusions of their research around the ‘Short Natural Dream’. After analyzing the genomes of mothers and daughtersthey concluded that the Sik3-N783Y (a variant of the Sik3 gene) would be behind this phenomenon. It is not the only one (the team has located five mutations in four different genes), but it seems the most relevant. The problem is that it was difficult to prove. So researchers They introduced The variant in laboratory mice and discovered that, indeed, it slept 31 minutes less than the rest without presenting any fatigue. In fact, with a little stimulation, they could be almost an hour without sleep. And how is it possible? Ying-Hui fu, the neuroscientific behind the investigation, explained in Nature magazine that “our bodies continue to function when we sleep. They detoxify and repair damage. These people (those who had the mutation) can perform those functions at a higher rate than others.” And this is interesting. A new family of medicines. Above all, because Sik3 could become a therapeutic objective. Today, we have several techniques and medications to regulate the expression of genes and, at least on paper, these variants that the Ying-Hui Fu team has located could constitute a ‘roadmap’ to enter the world of sleep products less. And, let’s be honest, the market is huge. The ambition for stealing hours to sleep is as old as man. Is what is behind energy drinkshe Recreational methylphenidate or the techniques for Learn to sleep just four hours: an unbridled career for flee from fatigue and exhaustion. The problem is that it has terrible consequences: they quickly arise immunological problems, Metaboliccardiac, Psychological and cognitive. Lack of sleep (or the dream of little caldiad) is closely related to an increase in coronary heart diseaseof the diabetes and of the obesity. You can also exercise pressure on personal relationships and lead to social isolation. A pill to limit The damage caused by the dream of poor quality It would be a bomb for large pharmaceuticals. Are we close to getting it? It is still early to put it in those terms, but for the first time in a long time it seems that we have a solid way to walk towards it. With all that that meansclear.

It is not a production crisis, it is a crisis of priorities: the European electric labyrinth

by

While the great powers of the world They are disputing strategic places for the extraction of essential minerals in technology, Like lithiumEurope is freeing a silent but equally criticism battle: electricity. The conflict. He Iberian Peninsula Blag and from Heathbrow Airport He has exposed the weaknesses of energy systems in Europe: Interconnection problems, lack of energy backup and deficiencies in networks. Although if it seemed little, energy expert Richard Milne for Financial Times He added that it is not a lack of capacity, but of how existing electricity is assigned. Exemplifying. Because to understand what the analyst refers to a good comparison. In his article, Richard Milne He explained that the Nordic countries – recognized by its high interconnection and Your ability to generate Large amounts of clean energy – are the perfect scenario to analyze how poorly equipped are European countries in a context where the demand for electricity continues to increase. On the one hand, the case of Norway where a data center for Tiktok has been prioritized in front of a strategic ammunition plant by virtue of the principle “first to arrive, first to be treated.” On the other hand, Sweden has supported steel projects to emerging battery companies for a national electricity supply share. After Northvolt’s bankruptcycritical voices have been raised that question whether to continue allocating large amounts of energy to green steel projects is sustainable. For its part, Greenland has abundant hydroelectric resources, but its leaders face a dilemma: to attract industries that generate employment or prioritize lower social impact projects, such as data centers? There are more cases. The situation is not exclusive to the Nordic countries. In Spain after the blackout, the difficulty of the “Energy Island” was evidenced, where The lack of interconnection It complicates the export of energy to other countries. In addition, the system lacks Storage infrastructure and Gridorming technology to stabilize the network. Instead, the situation in France is paradoxical. The production of renewables has grown so much that it has forced nuclear power plants To operate to the idle to avoid an excess of supply. This decision has caused Energy distribution problems. First to arrive, first to be treated. Richard Milne He has argued That the root of this European energy crisis is the result of uncoordinated climatic policies and a long -term lack of strategic vision. Instead of establishing clear priorities on which sectors they should receive electricity, governments have opted for a simplistic and disorderly approach. The answer from the Executive. The energy analyst has made special emphasis in which on the political level the answers have been disordered and uncoordinated. In the column he has detailed that while Norway has allocated its energy resources to the electrification of gas and oil plants, Sweden has opted for emerging battery companies. For its part, Greenland has discussed whether to prioritize high employment industries or projects with less social impact. However, until now there has been a concerted effort to establish a common strategic framework at European level that defines clear priorities over the use of green electricity. Forecasts. To avoid falling into a structural energy crisis, Europe needs strategic rethinking. Is it possible to establish a common criterion to decide which sectors should be prioritized? How can it be guaranteed that green energy really contributes to climatic objectives without compromising industrial development? As He has warned The energy analyst, Europe must initiate a serious and coordinated debate on the strategic uses of electricity, defining priorities based not only on economic criteria, but also on its environmental and social impact.

Sony Wh-1000xm6, features, price and technical file

by

Sony competes on many fronts, but there is a category where it has been marking the guideline: the headphones with active noise cancellation. The WH-1000X series has been able to stay as a generation after generation, thanks to constant improvements and well-measured. Three years after WH-1000XM5it is the turn of the WH-1000XM6. An update that does not seek to revolutionize, but to refine what already worked and raise the level in sound, functions and design. Technical sheet of the new Sony Wh 1000xm6 Sony Wh 1000xm6 ARCHITECTURE Circummural headphones closed with electrodynamic transducer DIAPHRAGM Carbon fiber transducer. Diameter: 30 mm Cancellation of noise ActiveEnvironmental sound capture mode Microphones 12 Microprocessors Sony HD Noise Cancelling Processor Qn3 Sony Integrated Processor V2 Wireless connectivity Bluetooth with LE and AUDIO SUPPORT Audio formats LDAC BATTERY Up to 30 hours (with cancellation of active noise) WEIGHT 254 g PRICE 469.99 euros Refining an outstanding experience Sony has decided to reinforce the point where the WH-1000XM5 did not just shine: the sound. As we point out in our analysisalthough they were convincing, they did not stand out as much as they did in cancellation of noise, autonomy or ergonomics. The new Wh-1000XM6 point out precisely there, with a renewed diaphragm unit and a redesigned coil that, according to Sony, allows a more precise and rich reproduction in nuances. The objective: achieve a more natural audio. The company has had the support of Masterization Engineers of studies such as Sterling Sound, Battery Studios and Coast Mastering. His work does not intend to turn these headphones into a study tool, but to ensure that what we hear better approaches the original intention of the artist. In addition to the classic Hi-Res and LDAC audio support, the DSEE Extreme with Edge-AI engine is maintained, which we already knew in the XM5. Their task is to recess the compressed files in real time and return part of the dynamic range they lose during compression. In practice, this translates into a more complete sound when we use streaming services with aggressive compression. A smartest noise cancellation At this point Sony already started from a solid base. The WH-1000XM5 offered one of the best cancellations in the market, especially when the conditions were unfavorable. With the XM6, the improvement comes from the hand of New QN3 HD processorwhich multiplies by seven the capacity of the previous chip and now manages 12 microphones instead of 8. WH-1000xm6 in platinum (left), in black (right) That is especially noticeable in scenarios with unpredictable noise: train stations, full coffee shops or environments with intermingled voices. The new system, combined with the adaptive NC optimiser, automatically adjusts the cancellation according to the environment and atmospheric pressure. The ambient sound mode has also been refined, which now better filters useful noises, such as a nearby voice or an acoustic signal. All this can be managed directly from the Sony application | Sound Connect, which allows automate sound profiles or set them manually to the user’s taste. In the XM5, the calls were already a jump with respect to previous models. Even so, there was a margin of improvement in complex situations, especially with wind or changing noise. The WH-1000xm6 raises the ribbon with a new system of six microphones with beam formation and a noise reduction algorithm optimized by AI. Sony’s promise is that, even when there are conversations or background trafficking, your voice will remain clear and separated from the environment. It is not only a matter of microphones, but of how that data is processed in real time. Most comfortable, improved folding and intuitive controls At first glance, the WH-1000XM6 do not present a radical jump in design with respect to the XM5, but there are several relevant changes. The headband is now wider and has redesigned with an asymmetric profile that facilitates identifying the left and right side of a look. It is covered with vegan skin, designed to offer a gentle and smooth adjustment. The pads have also been optimized for prolonged use, with a new elastic material that seeks reduce fatigue and better block outside noise. In the XM5 they already stood out for their comfort (250 grams of weight and a uniform distribution of pressure), and the XM6 further refine that approach, maintaining that sensation of headset does not bother even after several hours of use. XM6 premiere a new folding mechanism manufactured by metal injection, designed to offer more durability and facilitate transportation. The case, by the way, has also been redesigned: now it includes a magnetic closure and is easier to transport. As for the controls, Sony maintains the tactile system to manage reproduction, calls and sound modes. The intelligent functions section has also received a good dose of novelties.

Consistency is no longer a priority

If you think you are not the same person after a long shift, the science of being right. The reason is in the brain

Fatigue can affect us in different ways and the different contexts, it is something that we have surely perceived in our own meats, trying to remain awake at night, studying before an exam or during a prolonged trip. Also, it is likely, we have noticed it after a work day that for some reason we can have lengthened. Significant changes. A study has detected Neurological changes in professionals prolonged working hours. The study was conducted in health professionals who faced days above 52 hours per week. “The overfracha can induce neuroadotative changes that can affect cognitive and emotional health,” Explain the team responsible for the study. Although it is a pilot study, which implies caution when drawing conclusions, the work provides new evidence on the impact of excess work on our well -being and in our productivity. The price of excess work. The global cost of excess work It is considerable. Beyond conventional occupational hazards, overfracha It has been related with an increase in the risk associated with cardiovascular diseases or metabolic disorders, among other problems. Recently, A study Posted in the magazine Environment International He estimated in almost 750,000 deaths attributable to excess work in 2016. This resulted in the loss of more than 23 million years of life adjusted by disability (Daly) linked to certain cardiovascular diseases. Excess work, marked in the brain. In addition to physiological problems, excess work can also cause mental health problems. In an effort to better understand their neurological context, the team responsible for the new study began studying the brain of professionals in a field, that of medicine, where marathon days are relatively common. The team He turned to the Gachon Regional Cohort (Grocs) to obtain certain data, which complemented with magnetic resonance scanning, for which they had a total of 110 participants, the majority sanitary. 32 of the participants (28%) met the requirements to be included in the group of those who worked in excess, while the rest would have “standard” days. To study the changes, the team resorted to a technique called voxel -based morphometry (VBM), a useful technique when identifying and comparing regional differences in the gray matter of the brain. Changes in 17 brain regions. They ran into significant changes in some regions related to executive function and emotional regulation. An example cited by the team is in A 19% increase In the volume of the average frontal turn, an area involved in key cognitive functions. The analysis allowed to detect increases in 17 regions of the brain. One of these areas was the upper frontal turn, an area involved in attention, planning and decision making. Another area of ​​interest was the insula, key zone in the integration of sensory stimuli and engines, but also in emotional processing and understanding of the social context, the team points out. The details of the study were published In an article In the magazine Occupational & Environmental Medicine. Small scale. The team itself warns that there are limitations that imply the need to be cautious in the interpretation of the results. For example, this is a pilot study on a limited sample of participants. In addition, experimental and control groups are not random, which implies a possibility of self -selection and with it a possible bias in the analysis.
