Starship flight 9 includes such a risky maneuver that will be tested at sea, not to destroy the tower

After Two consecutive flights in which the Starship ship exploded shortly from separating from the propeller, a conservative approach could be expected by Spacex for the ninth launch. Nothing is further from reality. Double Tirabuzón without a network for the Super Heavy. Elon Musk’s company knows how to maintain emotion for flight 9, and the riskiest plans focus on The largest part of the rocket: The Super Heavy propeller. Spacex will not only reuse for the first time one of the three super heavy who have successfully landed in the arms of the launch tower. At the same time, plan to test With only two available engines For braking and landing maneuver. It is a deliberate resistance test to verify what would happen if a propellant engine fails during the reentry. Straight to the Gulf of Mexico. In this case, Spacex will not try to catch the propeller for the second time. The landing maneuver is so extreme (first super heavy used, with only two lit engines and without failure tolerance) that the rocket will discard. Instead of returning to the tower, he will make an essay of the maneuver in the Atlantic Ocean, finishing his mission with a shocking. Spacex already has a second Mechazilla tower in Starbase Able to catch rockets with his robotic armsbut he needs both for when, in addition to the 70 -meter Super Heavy propeller, the 50 -meter Starship ship begins to land in the other tower. Something that Spacex would have tried for the first time on this flight 9 if it had not been for the catastrophic failures of flights 7 and 8, which have delayed those plans. Even so, we are going to have fun. 29 used engines. Spacex has already done a proof of the propeller which will launch the Starship in this ninth launch: the Booster 14. He took off for the first time on January 16 and was successfully captured by the tower a few minutes later, while the starship lost control. The first time Spacex reused a falcon 9 propeller A year had passed Since its launch. With the Super Heavy just three months have passed. In addition, there is no trap or cardboard: 29 of the 33 engines that wears the booster 14 are used. Of course, Spacex is still far from rapid reuse type “Zero-Touch reflight“(land, load propellants and take off again) to which he aspires. Especially with the ship and its thermal shield. All eyes put on the ship. To land a used rocket of 70 meters high with a less engine is impressive, but the super heavy will not be the protagonist of this flight. It must necessarily be the Starship 35 because it is the third ship of version 2 that will launch Spacex. His two predecessors had an abrupt ending for excessive vibrations near the engineswhich led to leaks, fires and explosions. The S35 ship completed its cryogenic tests in mid -March, but has not made a long ignition like the S34, and there are doubts about how Spacex will face its launch, because the flight profile has not yet been published. Nor the results of the investigation on flight 8, nor the flight license of the Federal Aviation Administration, so it seems unlikely that Spacex takes off at the date initially scheduled (April 18). Mars does not expect. Yes, on the other hand, the investigation of flight 7 is closed, whose 11 corrective actions were implemented before flight 8. Without much success, since it failed again. Flight 9 is not expected to require a modification of the flight license, but the approval of the FAA is indispensable to schedule the launch. Spacex needs to accelerate the step to meet Elon Musk’s goal of an unmanned mission to Mars (with Robots Tesla Optimus) By the end of next year. The earth-marte transfer windows occur every two years, and Musk does not want to waste time. But Starship is already pushing the limits of technology and the last thing he needs is a third explosion about the Caribbean.

Some scientists have tested the “fasting 4: 3”. The results have been quite positive

He intermittent fasting It is perhaps the diet that has won the most popularity in recent years. The idea in broad strokes is not to focus on limiting what we eat but to limit the hours to which we do it. From this basic idea, there are several ways in which to limit our consumption depending on the hours and days we dedicate to fasting. Positive results. The last study in finding evidence of the effectiveness of these forms of dietary restriction has made it focusing on fasting 4: 3. The team responsible for the experiment observed that this form of fasting, in the context of a broad intervention that also included promotion of physical activity, led to a higher average reduction of the body mass of the participants in the study. 4: 3. In this analysis, the participants of the experimental group underwent the call Intermittent fasting 4: 3 (4: 3 IMF). This form of fasting implies limiting our caloric intake by 80% for three non -consecutive days per week. The intervenion was accompanied by a high intensity exhaustive program for weight loss. This program included behavioral support and recommendations to increase the physical activity of moderate intensity up to 300 minutes per week, explained the team responsible for the study. 12 months. For the analysis, the participants, 165 adults overweight or obesity were divided into two groups. The experimental group, which underwent the restriction described and a control group that underwent a caloric but constant caloric restriction diet in which caloric intake was reduced by about 34.3%. Both groups had the support intervention and in both cases diet and program were carried out for 12 months. “Modest” results. Although the difference between one group and another was “modest”, the team in charge of studying it observed that the experimental group reduced its body mass to a greater degree compared to the control group. The experimental group reduced its body mass in 7.6% on averagewhile in the control group the reduction was 5%. In addition, a greater proportion of participants in the experimental group managed to reduce their weight by 5% or more. In kilos, the average difference between one groups was almost 2.9 kg. The details of the work were published In an article In the magazine ANNALS OF INTERNAL MEDICINE. More than a matter of weight. There are diverse reasons that can lead to a person to lose weight. Aesthetics usually weighs a lot but the fact that overweight and obesity are risk factors in various diseases and disorders may be the most relevant. The causal interconnections that unite both factor are complex, so a lower body mass is not a good indicator of a health improvement. Therefore, the team also examined the effect of the diet on cardiometabolic markers such as blood pressure, cholesterol levels, or fasting glucose levels. These markers showed an improvement, the team added. In Xataka | For many, skipping dinner is part of your intermittent fasting. It is not always a good idea Image | Xataka with Gemini

We have tested the new Samsung Galaxy S25, three phones that stand out for their software and AI functions

January was not usually a month of big announcements and presentations, partly because of the MWC in Barcelona in February, an event that brings the world’s largest mobile manufacturers to Spain, and partly because of the numerous launches at the end of the year. above, like those of Apple, ALIVE and OPPO. However, Samsung has been presenting this month for a few years now. its most important terminalsthe Samsung Galaxy S. In this 2025 it is the turn of the three Samsung Galaxy S25 that has been shown at a world event in California that we have been able to attend. In it, the company has revealed the new features of these three terminals, which we have been able to test in a contact meeting in which we have confirmed that The biggest changes are not in the hardware, but in the software. It seems Samsung has followed the “If it works, don’t touch it” maxim, and sales of the S24 Series last year have been good enough that Samsung didn’t want to take any chances. However, we have improvements in performance, autonomy and in the larger model also in camera and ergonomics. We see the biggest changes in the softwareboth for the Android version and for the Samsung layer, One UI 7. But above all we see new features in the artificial intelligence functions. Samsung last year set a trend with Galaxy AI and this year it has not only maintained all those functions, but has also included other really useful ones, such as related to phone calls. Similar hardware The changes in the hardware of the new Galaxy S25 are few in the most economical models. The Galaxy S25 and S25+ only see performance and efficiency significantly modified. This is due to the processor leap, since now they implement the Qualcomm Snapdragon 8 Elitea chipset that we were able to test thoroughly in the realme GT 7 Pro and that left us with our mouths open. Here he promises the same. Samsung has confirmed to us that there have been company engineers integrating capabilities into the custom Qualcomm chipset, hence the chipset is called Snapdragon 8 Elite for Galaxy. In addition, all three models have a better vapor chamber with a larger size, 40% larger in the Ultra and 15% larger in the other two models. All versions They now start with 12 GB of RAM. There will be Wifi 7 in the Ultra and Wifi 6E in the other two models according to the company, which is strange because they all have the same processor. The UWB chip continues in the Ultra and Plus, like last year. We tested the Samsung Galaxy S25 Ultra, S25 and S25+ Adrian Raya The characteristics of cameras, screen, battery, charging system or design are the same as what we saw in the Galaxy S24. The Galaxy S25 remains the company’s most compact high-end and the S25+ is still a version of the same with better Wifi, UWB chip and a larger screen and battery. As for the Samsung Galaxy S25 Ultra, we do see more changes compared to its predecessorbut not many either. It is clear that the technology is already mature and we are not going to see major modifications. The most striking thing is that now its corners are roundedand that is greatly appreciated. Ergonomics was one of the few things that could be improved about its predecessor and now it is practically perfect. The material is still titanium, and aluminum in the S25 and S25+. Colors of the Samsung Galaxy S25 Ultra Alvarez del Vayo The Free Android As if that were not enough, They have slimmed down the phone by more than 10 gramsin addition to very slightly decreasing some physical dimensions. The screen also grows, 0.1 inches, but not so much due to the design change as due to the rounding of the corners and the reduction of its frames, which are now even smaller. It maintains the much-praised anti-reflective coating on the S24 Ultra. The negative part of the changes is the S-Pen, which loses Bluetooth capabilities. But the biggest change, along with the processor, is in the ultra wide angle camera, which finally goes from 12 Mpx to 50 Mpx, which place it next to the cameras of competitors such as OPPO, Xiaomi or VIVO. Samsung was one of the few companies that had not yet made the leap to this type of sensors in this type of cameras. Of course, both the front and the main rear and the telephoto lens remain the same. The VIVO X200 Pro and OPPO X8 Pro could take away the position of best camera of the year. Samsung Galaxy S25 and S25+ Alvarez del Vayo The Free Android We also have better night video recording, noise reduction systems, the possibility of recording in 10-bit HDR and LOG recording for professionals. In addition, a virtual variable opening system has been included. Bet on software All three models use the same software, One UI 7, which runs on Android 15. Samsung wanted these phones to be the first to have this version of the system in the brandat least in a stable way, because so far Android 15 updates on current models are in testing phases. One UI 7 runs on Android 15, which has major design changes in the icons, notification buttons, notification management, etc. New notification system on a Samsung Galaxy S25 Alvarez del Vayo The Free Android One of the changes that will be most controversial is the company’s commitment to a separate system of notifications and shortcuts at the top of the screen. Until now, Samsung let One UI work like native Android, that is, showing the shortcuts at the top and notifications below. With One UI 7 we see that this changes, and if we slide on the left side of the screen we have the notifications and if we slide on the right we have the shortcuts. Luckily, It’s easy to reverse … Read more
