Sending an email to a low employee has cost 1,500 euros to a company: it doesn’t matter if you respond or not

by

The Superior Court of Xustiza de Galicia (TSXG) has marked a before and after in the protection of the right to digital disconnection of workers in Spain. For the first time, a company has been convicted of sending electronic jobs to an employee who was on a medical leave. The sentence is considered a pioneer because, although other countries Like France and BelgiumThey have already legislated on digital disconnectionGalician justice has taken another step by sanctioning not only the obligation not to respond, but also the duty of the company of Do not send communications Out of working hours. What happened? According to details the sentencethe affected worker was in a situation of temporary disability due to an “anxiety disorder”, apparently “motivated by the emotional wear that implies the current situation of excess work, realization of overtime continuously and labor responsibility, which has led to the appearance of relational insecurity with respect to their environment.” In that context of medical disabilitythe employee continued to receive electronic emails related to her work during the entire low period. The company recognized the facts, but argued that the emails to the complainant were part of a thread created above and whose content was aimed at other people of the team. In addition, he claimed that they were not asked for “an immediate response.” In Xataka 40,000 euros for a croquette: Mercadona dismissed an employee for eating a croquette and must now compensate him The TSXG got serious with disconnection. In its resolution, the Superior Court dismissed the company’s arguments and was overwhelming in its ruling. The magistrates considered that the company not only breached their duty to refrain from communicating with the worker during his temporary disability, but also attempted against his moral integrity. According to the sentence, the Right to digital disconnection “It demands that communications from the company are not received outside the work time”, and warns that “that right is not fulfilled due to the fact that the working person does not have the duty to respond to the communications received outside the work time more or less immediately.” That is, and here the Importance of this resolutionthat the right to digital disconnection does not only refer to the interpretation of the urgency of the communications received, but “carries with it an obligation by the employer, and of dependent or linked persons, of abstention in the communications of labor order or linked to the provision of services outside the working time.” In Xataka Some employees sued their company for cutting the salary. The supreme has responded that being unpunctual is not a job Vulnerability situation. The TSXG highlights the special importance of the right to digital disconnection when the worker is in a situation of temporary disability by A psychic ailment. In the sentence, the Galician Court emphasizes that emails in these circumstances “uneasy the receiver, and also reifted it and undermined their dignity” and places the worker in a state of permanent availability incompatible with her right to recover without pressures. The right to digital disconnection in Spanish law. The right to digital disconnection is included in article 88 of the Organic Law 3/2018 and reinforced with the arrival of the call Distance Labor Law of 2021. According to the regulations, “all workers and public employees will have the right to digital disconnection in order to guarantee, outside the legal or conventionally established work time, respect for their rest time, permits and vacations, as well as their personal and family intimacy.” This right allows workers not to answer mails, calls, video calls or any other digital communication out of work hours. The law does not differentiate between the size of the workforce or the public or private nature of the company, so the protection is universal for all employees in Spain. With the TSXG ruling, the prohibition is not limited to the fact of “not answering” but its interpretation is expanded to “not receive.” {“Videid”: “X919SE0”, “Autoplay”: False, “Title”: “The AI ​​and the future of our work Silvia Rivela | 100 years, 100 visions Ep.3”, “Tag”: “”, “Duration”: “2630”} Symbolic condemnation, but pioneer. The process reached the TSXG as a result of a previous sentence in which, in addition to the violation of the right to digital disconnection of workers, compensation for violations of the right to honor and physical integrity were requested. In this case, the new resolution revokes these last two concepts because it has not been damaged physically or its honorability has been affected. However, it imposes compensation of 1,500 euros “for damages” for violating the right to digital disconnection because the company “was not guaranteed” of this right and points out that “pretending that it is available at any time of its life, including temporary disability, prevents the free development of personality and hinders the exercise of the field of intimacy of personal life of personal life.” In Xataka | 55,245 euros for eating a sandwich and a beer: Mercadona must compensate an employee for unfair dismissal Image | Unspash (Brian J.

We have found the matter that was missing in the universe. I was hidden in the filaments of the cosmic network

by

Where is the dark matter is one of the great mysteries of the cosmos, but if someone thought we had all the barionic matter (the “conventional” matter) in the cosmos … it was wrong. At least until now. What was missing. A new study He has found in the cosmic network the barionic matter that remained hidden and that would represent about half of the “conventional” matter of the universe (matter which in turn only represents about 15% of the total matter). He has achieved it thanks to rapid radio (FRB) bursts, mysterious radio wave bursts that run the cosmos occasionally and have served to “illuminate” the subject of this intergalactic network. A network of “highways” in space. The cosmic network is a series of filaments of enormous size located in the intergalactic space in which a good part of the subject of the universe is distributed. These filaments are stretched clouds of gas and particles whose characteristics We discover little by little. Recent studies had documented the existence of this elusive network. The fact that the gas and particles that compose it are inert and do not give off light made their observation very difficult, which required hundreds of hours of dedication by powerful telescopes like VLT (Vary Large Telescope) of the European Observatory Austral (ESO). DSA-110. For study, the team had to build its own observatory in the California desert, in DSA (Deep synoptic array) -110. The name DSA-110 refers to the fact that this is a telescope composed of a network of 110 antennas. FRB The new Observatory was responsible for the detection of 39 of the 69 FRB thanks to which the deccovement was possible. These bursts are intense intriguing radio signals that we occasionally receive from the cosmos. We do not know exactly its cause or causes, but we suspect that they can be caused by supernovae or similar events. Some of these frb are repeated periodically while others are punctual; The origin of some can be located in a concrete galaxy, that of others does not. The frb used in the study They had their origin at points located at distances between 11.74 million light years and 9,100 million light years. This last distance, marked by the event FRB 20230521B, now marks a record: that of the most distant gust detected. Illuminating the highway. According to Explain the team itself Responsible for the study, the FRB “shine through the fog of the intergalactic medium.” When studying how this light stops when you meet matter, it is possible to measure this mist. When crossing the filaments, the frb light also separates in different wavelengths, such as when we see that a white light breaks down when crossing a prism, generating an rainbow. The measure to which the light decomposes also offers key information about the medium that is going through. The details of the study were published In an article In the magazine Nature Astronomy. Halos or networks. So far the cosmological models indicated that there was more barionic matter in the universe than we were able to observe. The new estimate of the mass of the huge filaments of the cosmic network allows us to fill in these holes. The new estimate indicates that 76% of the conventional matter of the cosmos is in the intergalactic environment, while 15% would be in the “halos” of the galaxies, while the rest, about 9% of this matter, would be the subject of which the interior of the galaxies is composed: planet stars and everything that lives are already vast cosmic structures.

We have a new explanation for dark matter. We have found it in superconductivity

by

Dark matter remains one of the great mysteries that intrigue astrophysicists around the world. The existence of this matter is assumed by the generally accepted cosmological models, but when determining the nature of the elusive matter we only have more or less founded conjectures and speculation. A new explanation. A group of researchers has proposed a new mathematical model which offers an explanation of the nature and origin of dark matter. The origin of this matter would be in the Big Bangas a consequence of the collision of high -energy and no mass particles, which would have won a great mass after their union. “Dark matter began its life as relativistic particles with hardly any mass, almost like light,” pointed in a press release Robert Caldwell, co -author of the study. “It is totally antithetical about what is usually believed to be dark matter (…). Our theory tries to explain how it was light to become masses.” Perhaps the most important detail in this work is that the theory postulated by this team can be tested thanks to the cosmic microwave background (CMB). The dark matter. The Dark matter It is the proposed explanation to explain a series of anomalies observed in the movement of the great objects of the observable universe as galactic galaxies and clusters. If we analyze their movements and compare them with the models used to describe them, such as the theory of relativity, we encounter that something does not match. Something seems to be pulling the matter. The dark matter would be different from the conventional or barionic in the fact that it would not interact with the rest of known physical particles except in one way: through gravity. That is why it would be so elusive despite the fact that its gravitational influence is still apparent. According to estimates, dark matter represents 85% of the matter of the universe. Return to Big Bang. The new proposed hypothesis Point out that fast particles, similar to photons, were the ones that dominated the universe after the “burst” of the big Bang. However, in that initial “chaos”, these particles would have joined in pairs. As postulate, the spin, one of the properties of the subatomic particles, would have exerted magnet among these particles: as if it were objects with opposite poles, the opposite spins of the particles would have caused the fusion. The hypothesis also proposes that, when these particles are cooling over time, the “imbalance in its spins” would have caused a drastic reduction in its energy, resulting in cold and heavy particles, dark matter. The “inspiration” for this model would have come from an analogous phenomenon seen in electrons, in the Cooper’s pairs, which allows electrical conduction without resistance, superconductivity. The details of the study were published In an article In the magazine Physical Review Letters. Putting the theory to the test. One of the great strengths of this hypothesis is that it is possible to test it. The key is that, according to the model, this “non -relativistic mass condensate” would decide faster than the standard scenario predicts. Explains the team that this prediction can be tested thanks to the cosmic microwave background, a type of radiation remnant Big Bang.

Loneliness is already a matter of public health. We have more and more evidence that animals help us to placate it

by

In recent years, we have seen how loneliness has become a problem with numerous ramifications, including toilets. The “male solitude epidemic” is one of the faces that has given more to talk, but loneliness also affects other sectors of the population. And small details can help, if not to solve it, perhaps at least to relieve it. Pets. Domestic animals They can help To placate the feelings of loneliness, as a new study has observed. Interestingly, the study key is not in the company that they could offer, in themselves, these animals, but in their ability to boost and facilitate social interactions between people. The work was done in Australia and focused on two groups notoriously susceptible to this problem: older people and international students. The team found that animals could be useful to facilitate the interactions between these two groups, improving the well -being and health of both. “We find that older adults and international students experienced a significant decrease in feelings of loneliness and a significant increase in their health. The presence of living pets in particular helped break the ice and facilitated conversations between participants,” stood out in a press release Em Bould, co -author of the study. The cost of a silent epidemic. The loneliness It can impact us In different ways, not only in our well -being, but also in our physical and mental health. Loneliness can accelerate our cognitive deterioration and has also been linked to lower life expectancy. Pilot project. The study was based on a pilot project in which 30 elderly people participated in different residences of the Australian state of Victoria, as well as 11 international students. For 18 weeks, participants held periodic meetings, of one hour every week, in which various leisure activities linked to animals were carried out. There were also animals, and robotic versions of these. Some of the participants in the pilot project (six older people and 10 students) also participated in the evaluation of the program and subsequent study. These participants completed several surveys and also participated in a semi -structured survey. Measuring loneliness. Measuring loneliness is not simple, but there are some tools dedicated to this, such as the scale of the University of California in Los Angeles (UCLA), the one used in this analysis. The team also evaluated the health status of the participants, through an instrument of 5 dimensions-Europe. The evaluation was positive in both dimensions. The team responsible for this observed both a decrease in the sunny index and an ascent in the health index. The details of the study were published in an article in the magazine Complementary Therapies in Clinical Practice. Fight loneliness. The fact that in an era that stands out for advances in communication technologies La Soledad has acquired such dimensions is a sad irony. However, the important weight that loneliness can mean about our State forces us to take the problem very seriously.

We have found a “dark matter bridge” thanks to its predictions

by

Optical telescopes are instruments that allow us to see very distant objects thanks to the combination of lenses, objects that, through refraction, modify the path of light allowing us, among other things, to see objects unimaginably distant. However, there are other types of lenses that astronomers have used for a few years, gravitational lenses. An intergalactic “bridge”. Thanks to these lenses, a group of researchers He has discovered The remnants of an object that collided in the past with the galactic cluster of Perseus. Some remnants that have finally been detected thanks to the elusive dark matter. A resolved mystery. He Perseus cluster It is a group of galaxies located about 240 million light years from Earth. These clusters are formed from very high energy mergers, events that are among the most intense from the big Bang. Thanks to these mergers, Perseus has been accumulating An equivalent mass 600 billion the mass of our sun (or the equivalent to several hundred times the mass of our galaxy). Until now we believed that mergers were a thing of the past in this cluster, which was already in a kind of stable balance. However, more recent and detailed observations had shown clues of recent collisions that implied that Perseus He was not in the stability situation we thought. The mystery now, was to determine which object had recently collided with this Cluster And why we were not able to detect it. Now, it seems that we have resolved this enigma. Using lenses, otherwise. All thanks to the phenomenon we know as gravitational lens. This phenomenon, predicted by physicist Albert Einstein, is caused by gravity. This, far from “throwing” an object. It is common for astronomers to use this phenomenon as if it were an additional lens in a telescope, allowing to see beyond what in principle would be possible. In this new study, logic It has been the opposite: Use the bottom galaxies, to detect the lens, in this case, the one formed by dark matter. Display Dark matter bridge. Thus they found a huge cluster of dark matter, of an approximate mass of 200 billion solar masses and located around 1.4 million light years of the accumulation of Perseus. Between both structures a structure is extended that connects them, a “dark matter bridge” that the team considers direct evidence of the last collision. The collision would have occurred, according to team estimates, about 5,000 million years ago. “This is the piece that was missing and we were looking for,” James Jee, co -author of the study, stood out in a press release. From the Subaru telescope. The finding was made thanks to the observations made by the Subaru telescope of the National Astronomical Observatory of Japan, located in Mauna Kea, Hawaii. Specifically, the team resorted to the Sprime-Cam instrument of this 8.2 meter telescope. The details of the study were published In an article In the magazine Nature Astronomy. But is dark matter? Dark matter is one of the most popular enigmas of contemporary astrophysics. The generally accepted cosmological models are based on the existence of a “something” that interacts with “conventional” matter and energy through gravity. Dark matter is the name we give to what would otherwise be anomalies in astronomical observations. Still From the assumption about what There is this “something” And we are not, for example, using erroneous models, the nature of this matter remains one of the great mysteries of the cosmos.

It was a matter of time for others to imitate OpenAi

by

Artificial intelligence companies are making clear a message: accessing the most advanced functions of their chatbots requires paying, and increasingly. It is not a completely new something, but now they begin to appear subscription plans with three -digit prices. At the end of 2024, Openai surprised with Chatgpt Proa modality of 200 dollars a month focused on professional users. It was an important leap compared to the Plus Plan of 20 dollars. Now is Anthropic’s turn, which has launched its own premium proposal for Claude: We are talking about the Max Plan. Claude Max: More use, more expensive. Anthropic, founded by former OpenAI members, offers two variants of the Max Plan. The first costs $ 100 per month (about 90 euros plus VAT) and multiplies the use available in the 20 dollars for five. The second elevates the commitment to $ 200 per month (180 euros plus VAT), with twenty times more use than the basic plan. Both options are already available for those who need a capacity to use much greater than the standard. What does Anthropic offer in front of Openai? Both the 100 and 200 dollars plan give priority access to new functions and models, but with an important difference with respect to OpenAI. While Chatgpt Pro boasts of unlimited use, Claude Max imposes limits. They are quite generous, but they are there. Is the AI ​​price uploading? Artificial intelligence progresses fast and companies are taking advantage of that evolution to launch increasingly expensive plans with premium functions. Scott White, Product Manager of Anthropic, has already dropped in an interview with TechCrunch that could launch even more expensive subscriptions in the future. A career expensive towards profitability Startups such as Openai or Anthropic are not yet profitable. OpenAi has marked 2029 as a goal, According to The Information. Anthropic, meanwhile, continues to increase its income while trying not to be left behind. Along the way, he continues to burn resources as if there were no tomorrow. Startups has some notable advantages, such as the ability to assume high levels of risk and, above all, move very fast. Google or Microsoft, meanwhile, do not have these advantages, but their strength is in a financial support that allows them to move forward even if some of their most ambitious projects fail.

The US suspects that Nvidia chips are arriving in China through Malaysia: it has decided to take action on the matter

by

The United States and China fight an increasingly aggressive commercial war. In this pulse, both have imposed export controls to protect strategic sectors. Washington focuses on the most advanced chips, While Beijin responds with critical minerals restrictions. They seem firm measures, but everything indicates that they are not being fulfilled to the letter. Chinese is avoiding restrictions. At the beginning of last year we learned that the popular liberation army He had managed to do with the most powerful NVIDIA GPUs, among which were the GPU A100 and H100. This was particularly relevant because the export of these products is prohibited by the US Department of Commerce. {“Videid”: “X8WLH9Q”, “Autoplay”: False, “Title”: “United States vs. China: The chips war”, “Tag”: “Webedia-prod”, “Duration”: “1611”} And they were not only the Chinese armed forces: also universities and research centers controlled by the government were using prohibited products. Washington believes that this has been possible by different ways, but concluded that the main channel were intermediary countries that collaborate with the Asian giant. First Singapore, now Malaysia. As The Economist points out, Singapore was one Of the countries that raised suspicions, simply because the figures did not square. In the last quarter of 2023, Nvidia multiplied by five shipments to customers in Singapore compared to the same period of the previous year, which suggested a possible detour to Chinese users. HGX H200, one of Nvidia’s most advanced products Now the focus is in Malaysia. According to Financial TimesThe United States suspects that many of the Nvidia chips enter the country end up in Chinese hands, avoiding current commercial restrictions. Given this scenario, Washington has begun to press the Malaysian government to control the trail of these latest generation chips. Tracking shipments is not so easy. The Minister of Commerce, Tengku Zafrul Aziz, has taken note of the requirement of the US and, he explains, has formed an interministerial working group to collaborate. However, he warns, that tracing chips shipments along the supply chain is not as simple as it seems and that it is a broad effort. Malaysia has become One of the great world epicenters of data centers, which explains the massive arrival of chips for the facilities that support companies such as Microsoft or Bytedance, the Tiktok matrix. According to Aziz, Washington is also promoting internal measures to reinforce control over the supply chain. In Xataka The general director of AMD is in China with one purpose: to snatch the AI ​​market to NVIDIA Waiting for results. For now, it remains to be seen if the pressure of the North American country will take effect. Malaysia has reasons to cooperate: a commercial retaliation could put its flourishing data centers at risk. Fulfill could simply be a way to protect your strategic position on the global technological map. The US does not want to give the arm to twist. The United States is doing everything possible to limit China’s access to avant -garde chips, mainly because of the Dual use risk: civil technologies that can also be applied in the military field. The concern is that these advances end up reinforcing the defensive and offensive abilities of the Chinese army.

His first data revalidates Einstein and put the dark matter on the map

by

The Euclid telescope, launched in 2023 by the European Space Agency, has finished overwhelming its first great task. Designed to make a map in detail of the universe To help us understand dark matter and energy, Euclid has been analyzing three regions of heaven from point L2 of Lagrange. Despite being just the First mission data setwhich will extend at least until 2030, the European space telescope has already detected 26 million galaxies, some of which are 10.5 billion light years. Now the team, aided by volunteers and learning algorithms for reinforcement, has begun to publish the most complete and detailed map of the distribution of objects of the universe, which includes huge clusters of galaxies, bright quasars fed by supermassive black holes and gravitational lenses that divert the light of farthest objects. A first look at the Cosmic Network A deep field image of the Euclid space telescope Galaxies are not randomly distributed. They form a structure called Cosmic Network, similar to a web, whose filaments are made of ordinary matter and dark matter. Dark matter does not emit light, but affects the way galaxies are formed and evolved. Euclid accurately measures the shape, size and distance of galaxies to understand how the cosmic network is organized. He map that is makingwhose first three pieces have just completed, will be key to finding out what dark matter and dark energy are really. We know that dark matter exists because it gravitationally affects galaxies (it turns them faster than expected). And we know that there is a dark energy responsible for accelerating the universe. But they are a mystery. Different types of galaxies classified by human volunteers and the AI ​​of ESA Since its deployment, Euclid has sent 100 GB of data daily. It is impossible to manually classify each image, so scientists resorted to artificial intelligence and citizen science to classify 380,000 galaxies. 10,000 human volunteers collaborate in galaxyzoo.org To teach a so -called Zoobot to identify the different forms of galaxies. The volunteers classify the objects (“spirals”, “with arms”) and their responses are used to reset the AI ​​or readjust the accuracy of the algorithm. 5,000 strong gravitational lenses Gravitational lenses detected by Euclid One of the aspects that most excite scientists in the first Euclid data set are gravitational lenses. Euclid has already detected about 5,000 possible strong gravitational lenses, very rare objects that form obvious visual effects, such as arches or Einstein rings. These curvatures of space-time, predicted by the theory of general relativity, allow to observe distant objects that would otherwise be invisible, helping to understand how dark matter is distributed. It is expected that at the end of the mission, Euclid has identified about 100,000 strong lenses, multiplying the amount we currently know. Questions to solve The Euclid space telescope had a complicated deployment due to the accumulation of ice in its lens, but the ESA engineers managed to solve any setback. The results published today demonstrate the very high sensitivity of the telescope. During the next few years, Euclid will observe between 30 and 50 times these regions of the cosmos, accumulating more and more information and discovering new galaxies and phenomena. Added to the observations of the newly released NASA Spherex Telescopethe information we will have of the universe will increase exponentially. With the most detailed map of the universe, scientists will try to understand the nature of dark matter and dark energy, which make up 95% of the universe, and how they relate to each other, while solving other transcendental questions: what is the structure and history of the cosmic network? How has the expansion of the universe changed over time? Is the theory of the gravity of Einstein complete, or does it need large -scale modifications?

A new type of dark matter

by

The mystery of dark matter is one of the great unknowns that pursue the scientific community. Well, now this mystery could be folded. And it is that a group of researchers claims to have found indications of a second type of dark matter. Dark matter 2.0: A group of researchers has postulated A unique hypothesis to explain a chemical phenomenon observed in the central area of ​​our galaxy. Its proposal implies the existence of a new type of dark matter. “Loaded” hydrogen. The focus of the mystery is found in hydrogen clouds located near the center of our galaxy. What makes these clouds an enigma is the fact that they are positively loaded, that is, hydrogen atoms in them have lost their electrons. The problem is that we do not know what has caused the ionization of these clouds, what an energy enough event could the electrons of their atoms start. As explained Those responsible for the study, the “energy firms” that reach us from this region of the galaxy suggest the existence of “a constant, turbulent energy source.” The explanation to this phenomenon proposed by the team is related to dark matter, but has an important nuance. WIMP Dark matter is a key element of cosmological models that attempts to explain some anomalies detected in the movement of large space bodies, such as galaxies. Dark matter would represent about 85% of all matter existing in the universe and would only interact with the rest of the matter through gravity, hence we have not yet been able to detect it in another way other than through gravitational movements. One of the hypotheses that try to explain this phenomenon focuses on the so -called massive particles of weak interaction or WIMP (Weakly interacting massive partners). The new study indicates that these would not be responsible for what happens in the center of the galaxy. Mass of mass. The responsible team postulates that the particles responsible for ionizing hydrogen clouds are actually A new type of dark mattercharacterized by having a much lower dough than the WIMP would have. The new hypothesis postulates that these “tiny particles” would collide with each other producing in these charged particles, a physical process called “annihilation.” It would be in turn these charged particles that would be ionizing the gas clouds. The details of the study were published In an article In the magazine Physical Review Letters. Alternative hypothesis. As the team points out, so far the main suspects of this phenomenon were cosmic rays. The team maintains that the new theory explains the phenomenon with greater precision. And, according to the observations, the “energy firm” of the phenomena observed in this region does not seem intense enough to be attributed to the phenomenon of cosmic rays. This implies that the cause of this “annihilation” must be “slower than a cosmic and less massive ray than a wimp.” In Xataka | In the sky of the Canary Islands not only stars are seen: we have just discovered a superstierra only 56 light years Image | Nick Risinger

It doesn’t matter if you delete your messages on WhatsApp, Google keeps them the same. The State Attorney General has discovered him for the bad

by

Google and WhatsApp have confirmed to the Supreme Court that they will retain the data of Attorney General Álvaro García Ortiz, according to PUBLICA The country. The prosecutor is being investigated for alleged revelation of secrets By filtering information about an agreement offered by Alberto González Amador’s lawyer, a couple of Isabel Díaz Ayuso, to avoid jail for two fiscal crimes. Politics on the margin, they have opened an interesting debate about true privacy in digital environments. Why is it important. The case brings to light a non-tan-known technological reality: erasing messages or emails from our devices does not mean that they completely disappear from the servers of technology companies, which can be forced to recover them by judicial orders. Between bambalins. Messaging applications and mail services maintain backups and records that survive the local erase. WhatsApp does two types of copies: one on the device itself and one in virtual storage that It is managed through Google. This creates a persistent data network difficult to eliminate completely. The general panoramic. This case exemplifies the complex of the storage architectures used by large technological ones, at the technical and legal level: The data is fragmented and doubled on several servers, in turn in several jurisdictions. The backups They are made automatically and in the background, often without explicit knowledge of the user. Complete data elimination requires concrete actions beyond simple erased in the device. In detail. The technical procedure to recover “deleted” messages implies several layers: Forensic access to local copies through specialized software. Request for metadata records (who sent what and when). Recovery of backups in the cloud that can remain even after the local erase. Analysis of Logs of servers that record the activity of communications. The authorities are looking for very specific data that technological ones retain despite the local deletion by the user. Message content, multimedia files exchanged, communications metadata and activity and connection records. The big question. This case illustrates a reality that many users do not know: the elimination of messages on our devices does not guarantee their definitive disappearance. For the common citizen, this means rethinking what we understand by digital privacy; For professionals in sensitive positions, it implies assuming that any electronic communication could be recovered in a future judicial process, regardless of whether or not it was deleted. Will our communicative habits change when we assume that “erased” may not really be?
