The Angrois case reveals that it will not be quick

Because? If there is a question that circulates today in Spain, in the offices of Renfe, Adif and Iryo, the Ministry of Transport, the newsrooms of the media, the unions and of course in the streets and bars, it is this: Why? How is it possible that a practically new train, which it didn’t reach four yearsderailed yesterday afternoon on a track renovated in spring, leaving dozens of victims? All these doubts (and some more) must be answered by a team of experts in railway accidents, a special ‘CSI’ that it won’t be easy. The Government already warns that the investigation will last at least a monthbut previous incidents (including the fateful Angrois accident 2013) show that final conclusions may take much longer to arrive. What has happened? It is (unfortunately) the news of the day, if not of the month. Yesterday afternoon, around a quarter to eight, a train from the Iryo operator that covered the Malaga-Madrid route derailed near Adamuz (Córdoba) with 289 passengers on board, in addition to four crew members and the driver. The incident would have been serious in itself, but fate would have it that part of the convoy (Fracciarssa model) collided with another train that was traveling in the opposite direction just at that moment, a Renfe Alvia that covered the route between Puerta de Atocha and Huelva. The result: 39 deceased (at least) and more than 100 injured. “Very strange”. The Minister of Transport and Sustainable Mobility, Óscar Puente, was quick to express his surprise at the accident. Not only because of the collision, but because of the derailment itself, since both the machinery used by Iryo and the railway infrastructure were modern. “The Iryo train is practically new, I don’t know if it is four years old, and the track is a completely renovated track, in which 700 million have been invested. Specifically on that section, the work to replace switches, detours… was completed in May,” commented. “The accident is tremendously strange, on a straight line. All the experts we have been able to consult are tremendously surprised,” added the owner of Transport. “It is strange, it is very strange, it is difficult to explain at the moment. We hope that the investigation will help us clarify what has happened.” Of course, to know these explanations we will probably have to wait. Minimum one month. Puente already warns that it will take experts at least weeks to collect the data, analyze it and reach conclusions. “We will not have the resolution of the investigation for at least a month,” the minister explained before remembering that the investigations will be carried out, as stipulated by the regulations, by an independent commission that must “shed light and clarify the causes of what happened.” Although each accident has its peculiarities and is not comparable, previous railway incidents have required considerably more time. At least to obtain the reports with the final conclusions. How long? Beyond the investigations that can be opened by other means, Transport has a special body to clarify accidents like yesterday’s: the Railway Accident Investigation Commission (CIAF), an entity activated at the end of 2007 that acts with “full functional independence” and focuses on the technical study of incidents recorded on the General Interest Railway Network. Its objective is to analyze all types of incidents (including events without victims) and write “technical reports” that include recommendations. In your website The CIAF itself details that this document must be made public as soon as possible and even sets a time horizon: “This report will in principle be made public within a maximum period of 12 months from the date of the event.” Right now the commission has six investigations in progress corresponding to incidents that occurred between November 2023 and October 2025. The oldest was a derailment that occurred on November 26, 2023 near the Madrid-Atocha Cercanías station that left 14 injured and in which there were no serious injuries or deaths. The CIAF clarifies that at first it opened a preliminary study, but after its findings it decided to move on to a “formal investigation.” Is that all? Yes. And no. The CIAF is in a way the ‘CSI’ of railway accidents (in 2024 the Congress approved create an authority that investigates railway, maritime and civil aviation accidents), but that does not mean that it will be the only one to analyze what happened. At least in part. The Country advances that Iryo has claimed and an urgent report to the manufacturer who commissioned the last inspection of the train that derailed yesterday in Adamuz. Its a priori objective is not to analyze what happened, but rather the latest railroad examinations. Reviewing the case of Angrois. Although the Government warns that the investigation will last at least a month, studies of other recent accidents have required much longer. Perhaps the clearest and most media example is that of Angrois derailmentwhich occurred on July 24, 2013 in Galicia and left 80 dead. The final diagnosis came in June 2014. And it was not without controversy. In 2016 the European Railway Agency prepared a report (at the request of the EC) in which he warned that the CIAF’s work had not been independent and reproached it for not having overlooked “key elements.” Complex processes. That’s only as far as the CIAF is concerned. The Angrois incident also gave rise to a long judicial investigation that lasted eight years and accumulated thousands and thousands of pages. The victims and their families had to wait years to see the first conviction. In other incidents the CIAF final report has also been delayed more than a yearas occurred with the accident recorded in 2016 near Vigo and which resulted in three fatalities. Images | Álvaro F.

They are a quick way to check that the flight is going well

The process of entering a plane is anything but placid: a queue that seems eternal, making sure you don’t lose your luggage, your identification and other valuable objects, making sure you find your seat and where to put your suitcase. And in the middle, a lot of people in the same situation as you and who seem infinitely slower and more annoying than you. But that’s it, it’s already happened: you’ve already sat down, you’ve fastened your seatbelt and you’re waiting for takeoff. My condolences if it has touched you in the middle. If you are in the hallway, congratulations: you will be able to stretch a little more and get out more easily. And if you are at the window, you can better observe the takeoff and landing and rest your head. And furthermore, you will see better that triangle over the window. A triangle to enjoy the views and verify that everything is going well Sometimes it is red, sometimes it is black and it is not on all the windows: in fact there are usually one or two triangles on each side of the cabin and at a certain height above the seat on the side wall, which is why you may never have noticed them. Because we usually know where the nearest emergency exit is (thanks to the explanations of the flight attendants team), but the triangle is not so easy to see even though it is of crucial importance. In fact, you may have never seen it, but the cabin crew is very clear where it is both before and during the flight. As explains aviation expert and former commercial pilot Daniel Bubb, those triangles indicate the windows from which there is better vision of the wings. It is clear that in that window you can take very cool photos for Instagram, but the reason for being is different: “Helping crew members when there is an emergency or a failure in the flaps, slats, engine or other parts (…) It allows them to identify the location of the problem more quickly.” Knowing this, if you see the cabin crew looking out of that window from time to time it may give you a little respect, but a relatively frequent check does not mean that something is wrong, since it is also used to verify that the wing is deicing correctly and that everything is going well, he adds. Small, private planes and some older models do not have them as long as the triangles They are not mandatory but they are useful for the crew, but it is normal that you will find at least two. Each of them is located on each side of the plane, just above the window that lines up with the edges of the wing on the outside. Of course, if the plane is larger, there may be two triangles on each side, thus marking the leading edge and trailing edge of the wing. To that seat in aviation is known like the “William Shatner Seat”a cultural nod to the episode ‘Nightmare at 20,000 Feet’ of “The Twilight Zone“ October 1963 where Shatner saw a gremlin on the wing of the plane. I haven’t had the pleasure of seeing it, but yes that Simpsons reference in a House of Terror special. Going in that seat has its advantages. The first is obvious: it offers a magnificent point of view for taking photographs and videos. However, it can also be useful if you are not too excited about flying: you can see for yourself how everything is fine and the de-icing process before takeoff. In addition, it offers a smoother flight sensation as turbulence and abrupt landing and takeoff are less noticeable. It sounds so appealing that the next question would be to know which row that seat corresponds to, but as there are different models and configurations of airplanes, there is no single answer. Of course, if you want to increase the probability that it will be your turn, look at the seat map and select the ones closest to the ends of the wing. If one day you are lucky and your assigned seat is that, enjoy the views.

How to send files from your Android to an iPhone using Quick Share with AirDrop

Let’s explain to you how to send files and other elements from your Android mobile to an iPhone wearing Quick Sharethat now has started to be compatible with AirDroid. At the moment this is a function that Initially it is exclusive to Google Pixel 10 phonesalthough Google is already working on bringing it to other Android devices as well. Quick Share is Android’s feature for sharing files between Android or Windows devices, and AirDrop is Apple’s alternative for sharing items between your devices. Until now these were two separate standards, but Google has started to merge them. It’s two-way compatibility, so you can send things from Android to iOS, but also from iOS to Android. As we have told you, this innovation has first reached the Pixel 10, the flagship of Google phones, but the idea is to also bring it to other Android phones. Send files from Android to iPhone To send files to an iPhone using Quick Share, you will currently need to have a Pixel 10, and that it is updated to its latest version. Google has released the function with an update for Google Play System. This update will arrive progressively to all users, so if you don’t have it yet, you should have it soon. Once you have the function activated, what you have to do is enter the Android quick settings and choose the Quick Share function, then choosing the file you want to share. You will also have the Quick Share option in the share menu of your Android. Once you are on the screen to share elements with Quick Share, a list of nearby devices to send the file to will appear below, and in it Now nearby iPhones will appear. Then, choose the iPhone and its owner will receive your file as if it were from another iPhone through AirDroid. One thing you should keep in mind is that, to receive files from Quick Share, iPhones must have a setting activated. Specifically, you will have to go to the settings and configure AirDrop to receive files from “Everyone for 10 minutes.” Therefore, you can’t just send the file, the iPhone owner must know that you are going to send it to them and change this.

A quick look at the ten best -selling car brands in the world offers a dramatic conclusion: China has already won

17.29 million. That is the amount of electric cars and plug -in hybrids that, according to Autovista24they were sold last year. Suppose we take all those cars and reduce them to ten. What brands would be the most popular? Surely, don’t surprise us to find Tesla, Byd or BMW, but what will get attention is that of those ten cars that we have in front, six are Chinese. Of course, it has all the meaning of the world. The cast. According to the data of EV volumeslast year the electric cars represented 62.5% of the total electrified vehicles sold globally. PHEV, AKA plug -in hybrids, 37.5%. It is a sensitive change compared to the previous year, when the percentages were 69.3% and 30.7%, respectively. Why does an electric car have less autonomy than the announcing The list. The crown, of course, is for China byd with a 22.2% market share. It follows, and from afar, Tesla with 10.3%. It is the maximum exponent of the Western electric car, since BMW, Volkswagen and Mercedes-Benz just add up to 8% between the three. The rest of the brands are from China, as reflected in the graph shared by Rest of the World: Global Electric Car market share | Image: Rest of the World Normal. That China leads this ranking is completely normal, especially if we take into account that, So far this year58.1% of electric car records and 70.1% of plug -in hybrids have been in China. In the United States, which is the second country in the ranking, the figures are 9.5% and 5.2%, respectively. Spain does not appear in the electric cars ranking, but in hybrids with 1.6%. China had, and has everything necessary to eat the electric car market. Has a government that offers incentives for adoptioneconomic resources that They are invested in high -level infrastructure, competitive prices derived from the two above factors, supply chains and, something important, The production of about 80% of lithium batteries. International expansion. The most obvious success case is that of Byd, which in just a few years He has managed to overcome Tesla In sales. In China, meanwhile, Tesla is the third best selling brand with a 5.9% share. Byd dominates with a 31.4% quota followed, very far from Wuling (6%). The next natural step was, of course, expanding to the rest of the world and that happens, in the first instance, through Europe. The company’s idea is that 50% of its sales come from our market, which is why it wants to establish factories in Hungary and Türkiye. Other brands such as Omoda, Jaecoo and Mg They have also opted strong for our borders. Best -selling electric cars worldwide | Image: Highway24 The best selling is still Tesla, but … The photo changes even more if we look The best -selling electric cars listbecause on that list only one brand competes (and strong) against China: Tesla. Elon Musk’s signature stays with gold and silver thanks to his Tesla Model and and Model 3that so far this year have been the best -selling Bevs. All others are signed by Chinese brands, highlighting Byd, Geely and, curiously, Xiaomi, whose Xiaomi Su7 It has been the sixth best -selling electric car of the year.

WhatsApp finally has a quick and light application in Windows. Joy will last little

Meta launched WhatsApp for Windows and Macos In 2016. Since then, until 2022, the company had A slow and very little efficient customerfor a single reason: it was not a native application, but a web container based on WhatsApp Web, which implied slowness and enormous consumption of RAM. Better changes, changes worse. In 2022, WhatsApp on desktop made an praise leap forward, launching native messaging customers on both platforms and discarding the previous technology. According to Our own teststhe use of RAM in Windows went from 500 MB to 100 MB. The use of CPU making scroll, from 60 % to 20 %. Three years later, one step back, according to Windows Latest: WhatsApp beta (downloadable here) It is no longer native, it is a web container again that camouflages a browser. WhatsApp tricks and tips to hide you to the fullest and maintain your privacy Bad news. According to Windows Latest observations, made by analyzing the WhatsApp Beta processes in Windows Task Manager, Meta is using WebView2a technology that allows using the Microsoft engine within applications. Your own version of Framework Electrona standard in the industry. The bad news for the user in front of the application has nothing to do with using WebView2 in particular, but with abandoning the previous approach. This inefficient will be the new WhatsApp in Windows.Every time we open the new version, the application will have to load the web version internally, and in the background, an instance of the Microsoft Edge browser, on which Webview2 operates. Just as it happened with the version they developed from 2016 to 2022. It is very inefficient with respect to an application that uses Native Windows development platforms, such as UWP (Winui). In the absence of being able to prove it, Windows Delast tests demonstrate the step back, and are related to those made in Xataka in 2022. The new version of WhatsApp Web consumes 30% more of RAM than the version available until today in the Windows application store. It is a developing version that can be optimized more, but leaving the native approach has inevitable negative consequences. In Reddit Han accomplished that the new client consumes up to 1 GB of RAM. Goal explains why a native application is more efficient. When they launched the current client, goal created a website in which they explain the Benefits of a native application very clearly: “They provide greater performance and reliability, more ways of collaborating and functions that improve your productivity” “They are designed and optimized for your computer operating system” “They offer greater reliability and speed” Why use web apps instead of native. Being so clear the advantages of a native development, and even being defended by goal, why go back? The industry resorts to web -based applications for a very simple reason: unify developments and guarantee functions and compatibility parity between different operating systems. If a company builds a single website, you can easily adapt it to Windows, Macos, Windows, Linux and Android, as well as offer it in browsers. Optimization is sacrificed, but the deadlines are expedited and the size of the equipment required to move forward and maintain a project is reduced. Mark Zuckerberg himself said that IOS’s old Facebook app was bad because it was based on html. They went to native development and everything improved. The same In Android.

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

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.
