In 2021 a volcano spent three days in eruption without anyone finding out. Now it helps us ahead of the silent volcanoes

by

Knowing how to read the signals that a volcano gives before erupting can make a difference between a scare and a tragedy. Some volcanoes make it easy for experts who know how to read these clues but others erupt without prior notice. Or maybe just we couldn’t decipher your signs. At least until now. A new tool. A team of researchers He has devised A new mechanism to model the behavior of some volcanoes. This tool, its creators stand out, will serve to more effectively monitor the eruptions of some volcanoes reducing the risk associated with these natural phenomena often so violent. Some special usefulness in the case of “silent” volcanoes. “Despite great advances in monitoring, some volcanoes erupt with minimally detectable or even without them precursors, significantly increasing the risk of nearby populations,” pointed in a press release Yuyu Li, co -author of the study. As explained by LI herself, some of these volcanoes are located not only near communities, also near important air traffic routes. Silent volcanoes. For the development of its tool, the team resorted to the Veniaminaf volcano, located in the North American state of Alaska. This is one of the so -called “silent” volcanoes, volcanoes whose eruption is not preceded by the signals that are generally associated with an imminent or close eruption, such as earthquakes or the deformation of the soil in the surroundings of the Magma Chamber. Veniaminof’s is just an example that We can find In this family of silent volcanoes that also includes some closer such as Stromboli in Italy or Popocatepetl in Mexico. Looking inside the volcano. But among all of them, the Veniaminof volcano is perhaps the most paradigmatic. Not because only two of the 13 rashes that have leaded since 1993 have been planned, but because in 2021 he achieved the milestone of erupting without anyone noticing Until three days later. The team responsible for the study analyzed the internal conditions that make it a silent volcano. Factors such as a slow supply of magma and a warm host rock are key in this regard. The monitoring of the volcano was carried out for three summers prior to one of the silent eruptions of the volcano, that of 2018. A model to get ahead of the eruption. The result, a model that conforms to the state of different variables that can condition the probability of the burst of the magma, such as the volume of the reserve, flow conditions of the magna, depth of the reserve or the form that it acquires is. Thus they could estimate what kind of conditions could be linked to a silent eruption and which ones were not. The team found that soil deformation could help prevent some eruptions of the volcano but that the relationship between underground magma and rashes were somewhat more complex than it might seem. The details of the study have been published In an article In the magazine Frontiers in Earth Science. The following steps. Monitoring the numerous silent volcanoes distributed throughout the world will not be an easy task. For now, the resolution gives a clue to what are the volcanoes to monitor more closely: volcanoes with small and warm reserves and slow magma flows, explains the team.

There is already a detainee for using the Meta Ray-Ban to record without consent. Recorded hundreds of women in Barcelona without finding out

by

A young man has been arrested in Barcelona After recording hundreds of women with smart glasses without their knowledge. What he did with those recordings: use them in their “seduction” courses that sold for 3,000 euros. Why is it important. It is the first known case in Spain where Ray-Ban Meta They are used to commit crimes against intimacy. The victims did not know that a camera that they did not detect recorded conversations about personal information that later disseminated and monetized. The facts. The detainee approached foreign tourists in Barcelona, ​​held apparently casual conversations and recorded them with glasses that had an integrated camera. Without noticing it, and in fact hiding it. The videos were later published in Tiktok and Instagram as a claim for their “seduction techniques” courses. In figures: 329 videos analyzed by the police. 239 Conversations with intimate data of women. 700,000 visualizations reached the video of the complainant. 3,000 euros cost the full course (plus 45 euros per month of subscription) The technical problem. The Ray-Ban Meta (329 euros) emit a white light when recording, but it is easy to hide them with small tricks. The majority of victims did not detect being recorded, according to police investigation. Smart glasses pose a privacy dilemma that we had not had to face so far, although it already anticipated a decade ago with The Google Glass opening the way. Ray-Ban Meta are much more concealed. Let’s not talk compared to a mobile. Yes, but. Goal designed a safeguard: the indicator light. The problem arises when malicious users deliberately avoid them to record without consent and then make malicious use, or at least to monetize or spread them. Goal is preparing more AI functions for these glasses that will identify places or people in real time. Some users have achieved it on their own. This arrest promises to be the first of many conflicts that are yet to come between body technology and privacy.

Chrome’s extensions have a big problem. Anyone can buy them and fill them with malware without finding out

by

One day John Tuckner decided to try to be evil. He found a browser extension called “Website Blocker” that could buy for $ 50 and took it. The extension, which allows to block certain websites so that the user is not distracted with them for some time, was especially interesting because it allowed to reuse it for spam attacks. And then things happened. Sight problem. In just a few days I had control of the extension and could do what I wanted with it. He modified the code, published the update and confirmed that the novelties had reached all users without being found. And then told what was happening: He is the founder of the cybersecurity company Secure Annex, and wanted to confirm their fears: there is great danger with extensions: anyone can buy them, modify them and reuse them for all kinds of purposes. Google reviews the modifications, but “it is not clear about what level of scrutiny,” Tuckner explained. Another recent case. At the end of January the creator of the Browser Boost Extra Tools for Chrome extension sold this development and transferred it to its new owner. Its 30,000 users were soon exposed to the new code, which dynamically redirected websites that the new owner decided unilaterally. I have not been. One of the extension users He warned of the problem in the github repository of the extension and analyzed the code notifying the danger of malware that could reach due to the new owner. The creator, n0m1111, explained who had sold the extension months ago and was no longer responsible for the code. Playing with permits. These extensions often allow permits of all types of browser parameters. Tuckner explained how in the extension he bought a permit called “declarativemetretreQuest” was used that was very wide and allowed to redirect users to false authentication sites to steal their passwords. Other permits would allow the owner of an extension to take screenshots with sensitive information or access the cookies that the browser keeps to steal data from the browser sessions. The possibilities are multiple and in Xataka we already talked a few months ago about how extensions They are becoming a silent method to infect users. A recent attack. In February, the Gitlab Threat Intelligence expert team They discovered A group of 16 Chrome extensions “used to inject code into browse to facilitate advertising and SEO fraud.” Among them they added 3.2 million users, and in Gitlab confirmed that the extensions had been bought and then modified, which allowed to avoid suspicions by users and the industry itself. These experts notified Google of the problem, and the company eliminated them all in January 2025. Block extensions, the solution. If you want to protect yourself from these problems, the solution is block The execution of extensions in your browser, especially in computers that handle sensitive data such as work. Unless they are extensions of trust, these types of problems can cause serious security problems. Care with permissions. Browser extensions can end up being bought, sold and reused without notice by their new owners, as has been the case. That raises a serious problem for users and companies, which before installing an extension should provide A lot of attention to permits that ask for these extensions to work. What do they say in Google. In Xataka we have contacted Google responsible and we will update this article if we receive new data on the subject. Be that as it may, the company offers A HELP DOCUMENT In this regard and also indicated in a Article in your official blog How to stay safe with the use of extensions in Google Chrome.

Finding quick and reliable tests for Alzheimer’s is a key mission for science. And we have a new candidate

by

Ahead of Alzheimer’s. It is a simple but difficult objective to achieve since the symptoms of this disease tend to appear when the disorder is advanced and has already caused important damage to our brain. A difficult objective but what It can help us treat the disease With greater efficacy, managing to delay the appearance of some of its symptoms such as cognitive deterioration. Maybe one day helps us cure it. In the blood. A group of researchers has tested a new blood test aimed at the early detection of Alzheimer’s disease. The test is based on a biomarker present in the blood, P-TAU217, which shows changes long before the appearance of symptoms in people with the disease. The study showed precision when detecting the disease greater than 90%. These results also did not depend on the age or gender of the participants, either on the existence of comorbidities or whether the test was carried out by specialists or primary care personnel. This marker can be measured with simple and cheap tools and the process is automatic, which can facilitate detection in various circumstances, democratizing the diagnosis of the disease. “This is an important step to bring simple blood tests for Alzheimer’s disease to health systems around the world,” said the team responsible for the essay in a press release. P-TAU217. Detection methods based on the P-TAU217 compound They are not exactly new. These types of tools are already implemented in the United States and it is expected that they will soon reach the rest of the world, says the team itself. The new method seeks to offer a simpler alternative to the available tools. The new study analyzed the precision of this New Test in the conditions in which it would be used, not only in specialized clinics but also in primary care. In three countries. The essay was carried out from 1,767 participants with cognitive symptoms distributed in three countries: Spain, Italy and Sweden. The details of the study were published In an article In the magazine Nature Medicine. The New Test included two cut points. One of them served to interpret the negative results: from this threshold the test rules out the presence of the disease. The second of the cut points serves to find the positive ones: this threshold shows the presence of the disease. This leaves, between one cut and another, a “gray zone” in which the results are inconcuing, however the use of a test with a single threshold slightly reduced the accuracy of the diagnostic tool. Above 90%. The study showed that the test achieved an accuracy between 92% and 94% when used in its two cuts mode. However, this precision fell to levels between 83% and 87% when only a cutting point was used and applied to more advanced ages. “When the method was tested in patient sides, the precision was between 92% and 94%,” NOëlle Warmenhoven explainedfirst signer of the study. “This is promising since this method will probably become one of the most used in clinical practice around the world.” In Xataka | We have a new “theory of all” to understand Alzheimer’s.

the challenge of finding 500 billion dollars for the largest AI project

by

He Project Stargate announcement This week was surprising for many things, but above all it was surprising for one: the 500,000 million dollars that will theoretically be invested in the next four years to achieve its objectives. The figure, absolutely colossalhas generated many suspicions. And rightly so. 100,000 million to start. Of that total figure, the announcement made it clear that the companies that provided the capital would invest “100 billion dollars immediately,” but even that does not seem easily achievable. SoftBank and OpenAI, those who will invest the most. In The Information reveal that SoftBank and OpenAI will contribute $19 billion each for the Stargate project. Bloomberg duck that both will also be the ones that will have the most participation in the final company: each will have a 40% participation. Musk attacks, Altman defends himself. The announcement of the project provoked a quick reaction from Elon Musk, who stated in X that “Actually they (the companies involved) do not have the money). He later added that “SoftBank has less than $10 billion guaranteed. I have good sources.” Sam Altman responded to those allegations hours later indicating that the data that Musk provided was “Incorrect, as you probably know.” Musk and xAI compete with OpeenAI and maintain a long rivalry, but here Altman surprised further telling Musk that “I truly respect what you have accomplished and believe you are the most inspiring entrepreneur of our era.” SoftBank under review. Analyst MG Siegler indicates in your newsletter that SoftBank has about $30 billion in cash. It seems to have room for that initial investment, but there are other data that work against it. As indicated user David Manheim on X, SoftBank’s investment fund has had notable failures in the past. On Wikipedia you can see how SoftBank Vision Fund lost $27.4 billion in 2022 due to several failed investments led by Masayoshi Son, the CEO of SoftBank. Among them is the investment of 100 million dollars in FTX, which then collapsed. OpenAI burning money. There are also questions about OpenAI’s ability to invest that amount. It is true that it has raised significant sums in the latest investment rounds, but the company is a money burning machine. Arab money and debt as exits. As the aforementioned Siegler article reveals, an important part of that investment may come from the United Arab Emirates through MGX, the investment fund. Another option is to resort to debt, which has already been very common in SoftBank’s investments (they have 150,000 million invested with that formula). Meanwhile, OpenAI looks for other girlfriends (Oracle). The project is also revealing other parallel movements. In The Wall Street Journal They highlight how OpenAI is beginning to look for options for its alliance with Microsoft, something that both have admitted. At OpenAI they complain that Microsoft does not give them the computing power they need, and they seem to be testing alternatives like Google. Perhaps Oracle is also among the candidates, especially now that it will be one of the participants (along with NVIDIA) in the creation of the large data center in Texas. It seems clear that OpenAI wants to not depend so much on Microsoft (or anyone) and Stargate may be a vehicle to achieve this.
