The SR-72, dubbed "The Blackbird's Son," is a top-secret U.S. Air Force project that promises to revolutionize hypersonic aviation with speeds in excess of 6,400 km/h. Scheduled for 2025, this unmanned aircraft may be the fastest ever designed.

The American company Lockheed Martin, through its advanced development programs, is working on the SR-72, a direct evolution of the legendary SR-71 Blackbird. This new model, fully automated, is intended for reconnaissance, surveillance and intelligence (ISR) missions. Its ability to achieve and maintain hypersonic speeds will give it an important strategic advantage on moderns.

In addition to its ISR functions, the SR-72 is designed to support Lockheed Martin's new hypersonic weapon system, the High-Speed Weapon (HSSW). This combination will greatly increase its offensive capabilities. They will allow it to fire accurately in high-risk areas where manned aircraft could not operate effectively.

THE SR-72 CAN FLY AT MORE THAN 6400 KM/H
The SR-72 is programmed to reach a speed of more than 6,400 km/h, which is about five times the speed of sound. For comparison, a modern airliner generally travels at about 900 km/h, while a standard fighter aircraft can reach up to 2,500 km/h.

Designed without a pilot to minimize risk and maximize performance, the SR-72 incorporates advanced autonomous piloting technologies. Initial test flights are scheduled for 2025, allowing it to test its unique hypersonic flight capabilities. Its engine technology combines jet engine characteristics for takeoff and landing with rocket engine characteristics for very high-speed flight phases. This technical requirement places him in a separate category, allowing him to cover intercontinental distances in record time.

This aircraft, scheduled to enter service by 2030, and for film lovers, the design of the SR-72 is very reminiscent of the Darkstar aircraft in the movie "Top Gun Maverick." Some rumors suggested that it could be a real prototype.

Google Messages introduces an expected feature that allows you to completely hide messages from blocked contacts, including in group discussions. But even if it allows you to stop seeing their messages, they can still see yours.

this year, Google Messages introduced an option to react to messages with lightning speed. With a simple double tap, users can now send reactions like lifted thumbs or hearts. This feature is designed to align this email with similar applications like Telegram and Instagram.

However, in response to user feedback that found some animations too invasive, Google has also added the ability to disable them. This option allows everyone to configure the appearance and behavior of the application according to their preferences. In addition, sending multiple photos has been greatly simplified, with a new interface that now allows you to select and send multiple images simultaneously. It makes sharing our best moments smoother and more enjoyable.

Beyond these improvements, the latest beta of Google Messages has recently integrated a very requested feature: now, if a contact is blocked, its messages will be completely invisible in groups of cats. This marks an important evolution compared to previous versions, where blocking a contact did not remove it from group conversations. This new feature aims to offer more control and security to users who want to avoid any unwanted contact.

Curiously, even if a user will no longer see the messages of a blocked contact in a group chat, the latter will still be able to see the user's messages. This feature may seem surprising, but it allows to continue to communicate in one direction only.

Also, when there are blocked contacts in a group conversation, a notification appears to inform the user that they may not see all the messages in the chat. This feature is currently being tested in the beta version of Google Messages and could soon be rolled out to all users.

TikTok adopts a new tool to better identify content created with artificial intelligence on the social network. It is in addition to the one it already uses for transparency purposes.

Since the massive rise of generative artificial intelligence tools, it has never been easier to make realistic photos, images, sounds or videos. This is not necessarily a problem in itself, but it becomes a problem when creation is presented as true. Of course, it is theoretically possible to recognize certain AI contents with the naked eye, except that it is not always obvious. And when they are disseminated on a large scale via social networks, the impact can be enormous.

On TikTok, for example, fake news from AI is increasingly present. Aware that this technology "offers incredible creative opportunities, but can confuse or mislead viewers [...]," the Chinese platform launched last year a clear identification system for all content made with the artificial intelligence tools it offers. However, this does not prevent anyone from uploading an AI video created with, for example, Sora from OpenAI and not specifying anything. This point will change.

TikTok announces the automatic implementation of a specific symbol: Content Crédentials (cr) developed by the Coalition for Content Provenance and Authenticity (CP2A). It may not be unknown to you, it is the one that Adobe unveiled last year with the aim of making it a universal label. Microsoft has already adopted it for example. This system adds metadata to the content, which is used to clearly recognize and identify those created by artificial intelligence.

The "cr" logo is to images and videos now, while audio-only content will benefit "soon," without being more precise. TikTok, still threatened with being banned from the United States, wants to be as transparent as possible, along with Facebook, Instagram and Google. has its own way of identifying content generated by AI, but China's social network is the first video sharing platform to implement CP2A technology.

The first-ever laptop with LPCAMM2 memory is launched. This new technology, featured on the Lenovo ThinkPad P1, combines power efficiency and ease of upgrade, a first.

Memory in laptops takes another step forward with the introduction of LPCAMM2 in the seventh-generation Lenovo ThinkPad P1. Unlike the usual memories, which are often soldered to the motherboard and difficult to replace, the latter uses a module that can be easily exchanged. This innovation provides great flexibility for users who want to increase the capabilities of their device without technical complications.

The LPCAMM2, or Low Consumption Compression Attached Memory Module, does not sacrifice energy efficiency for modularity. This type of memory attaches to the motherboard with screws rather than solder, making it easier to access and replace. This represents an important step forward compared to traditional DDR RAM bars that are included in slots on the motherboard. In addition, each module can manage two communication channels at the same time. This allows one to be used to make the system inside the computer simpler while improving its performance.

LPCAMM2 EASILY IMPROVES THE MEMORY OF A PORTABLE PC
iFixit, known for its detailed repair guides, is about the LPCAMM2. This technology solves an old problem: choosing between an easy-to-replace memory or one that saves battery life. Historically, LPDDR memory was supposed to be welded near the processor. This helped maintain a good low-voltage signal, but made repairs and improvements difficult. This new generation changes everything. It combines the speed and energy efficiency of the LPDDR with a modular design. It is simply secured with screws, making it easy to upgrade and repair.

This new generation of Rams integrated into the new Lenovo laptop is designed to be easy to update or replace. It is therefore ideal for improving your computer's performance without sending it to after-sales service. Approved by JEDEC, a standards organization, and supported by major brands such as Samsung and ADATA, the LPCAMM2 is a step forward towards more durable and repairable computers. It thus reduces the cases of programmed obsolescence and the waste that is gradually invading our planet.

Google is rolling out an update on how to secure access to our account. It gets rid of a painful and not necessarily the most effective method.

Long gone are the days when it was enough to enter our ID and then our password to access an online service. This is still possible, of course, but most of them now offer or even require the addition of an additional layer of security with dual authentication (2FA). Also called two-step validation, it is the system that asks you, for example, to enter a code received by SMS or to identify yourself on a smartphone associated with your fingerprint.

Google has been doing this for a long time. It has changed over time and some of you may remember a time when mobile notification was not the default method. Overall, protecting your Google account with two-step validation is pretty simple. But there is an obligation that can rightly put off. Before you can put it in place, you need to indicate your cell phone number. When you see how easy it is for malicious people to get hold of it, there is reason to hesitate. Fortunately, this is no longer a concern.

IT IS POSSIBLE TO SECURE YOUR GOOGLE ACCOUNT MORE EASILY NOW
In a blog post, Google announces that you no longer need to provide your mobile number to activate dual authentication. Instead, you can now secure your account using the Google Authenticator application or a physical key. As a reminder, the app gives a single-use code limited in time to enter just after writing your password.

Another interesting change is that disabling two-step validation no longer removes secondary security methods that have been put in place, as was the case before. For example, it is possible not to use 2FA, but to keep the required pass through Google Authenticator or a second smartphone. The update incorporating these changes is being deployed for all users of a personal Google account or Workspace.

The Tesla Model 3 has just won a fast charging contest simulating a gas station. Despite a less powerful battery architecture than its competitors, it overtook them with a little trick.

In electric vehicles, fast charging has become a key criterion for users, as it minimizes downtime on long journeys and offers a convenience comparable to traditional gas filling. Until the recent release of the Cybertruck, Tesla had not adopted the 800V architecture. Meanwhile, its main competitors, such as NIO, XPeng, BYD, Hyundai, KIA and Porsche, have already launched cars capable of charging at 80% in just 20 minutes.

However, Tesla has embarked on a different strategy by developing its network of Superchargers. Rather than equip each vehicle with an 800V charging system, the company preferred to operate its existing network of stations, mostly in 400V. This decision proved to be a wise one, as it allows the U.S. manufacturer to make the most of its charging infrastructure without requiring costly upgrades for each model.

To highlight the effectiveness of its strategy, Tesla was recently awarded the charging capability of its Model 3, in propulsion configuration, in a test designed to simulate a gas station stop. The MP6 test, developed by independent automotive consultant AMCI, estimates how many kilometers an electric vehicle can add to its range in just 6 minutes. That's the average time a driver spends at a gas pump.

In this test, the Model 3 has managed to add more than 96 kilometers to its range. That's almost double the performance of most of its competitors, including those with 800V systems. This impressive result highlights the efficiency of Tesla's Supercharger network. It shows that even without the most advanced charging architecture, these vehicles offer fast charging.

However, it is important to note that without access to a Supercharger, this fast charging performance is not achievable. While the 96 km added in just 6 minutes is sufficient for daily city trips, this capacity depends entirely on the availability of these stations.
