The new arms race is being fought at more than 6,000 km/h. And America is late

by

At more than 6,000 km/h there is no room to think twice. The new generation of hypersonic missiles operates in that speed range, a terrain in which the global military balance begins to shift. Russia and China they have already shown systems capable of flying above Mach 5. The United States, accustomed to setting the technological pace, moves forward with more doubts than it would like. The term “hypersonic” is not military marketing, but a clear category: devices that travel faster than five times the speed of sound. The real complexity comes with the trajectory. Unlike ballistic missiles, which ascend and descend in an arc, these systems can stay relatively low and change course in flight. This ability to maneuver, added to the thermal loads and ionization they suffer when passing through the atmosphere at such speed, explains why their development is so challenging. Hypersonic weapons enter the scene Russia was the first to proclaim operational capabilities. Its Avangard system, an intercontinental missile-launched glider vehicle, was announced for service in 2019 and Moscow claims it can carry a nuclear warhead. Experts in kyiv also claim that Russia used the zircon against the ukrainian capital in February 2024. China, for its part, demonstrated the DF-17 and tested the DF-27, which according to reports from 2023 flew about 2,100 kilometers in 12 minutes. In addition, it has shown the YJ-21, integrated into destroyers and bombers, consolidating a more visible deployment. The United States has focused on the Long-Range Hypersonic Weapon. Dark Eagle has a range greater than about 1,725 ​​miles, that is, about 2,780 kilometers, and a first system valued at about 2.7 billion dollars, according to the Government Accountability Office (GAO). The official plan aims to deploy it at the end of 2025, after a sequence of tests with failures in 2023 and 2024 that the GAO collected in June 2025. In August 2024, the CRS reported of the first satisfactory end-to-end flight. In parallel, the Navy is leading a common glider vehicle and the Air Force is working on an air-launched glider and a cruise ship with DARPA. The hypersonic threat tests the most fragile link in modern defense: time. The radar has less useful horizon at low altitude and Trajectory changes break prediction patterns. Furthermore, the dynamics of flight itself generate phenomena that can complicate detection. The forces trying to stop these systems are working on layers of sensors, more advanced tracking algorithms and more agile data links, but it is a challenge that is not yet solved. What sets hypersonic weapons apart is not just their performance, but the effect they have on the logic of deterrence. The impossibility of knowing what type of cargo they are carrying until impact creates fertile ground for misunderstandings. The United States assures that its development focuses on conventional ammunition, but rivals such as Russia and China have shown systems directly linked to their nuclear arsenal, which fuels distrust. Faced with this scenario, the allies are rearming their surveillance and defense architecture. In 2022, the United States, the United Kingdom and Australia expanded their cooperation within the framework of AUKUS to include “hypersonics and counter-hypersonics“, with emphasis on distributed sensors, shared intelligence and new interceptors. The objective is not only to have equivalent missiles, but to build a system capable of detecting threats in early phases and coordinating the response between different military nodes. The focus is on the next deployment milestones and on validating that this cooperation translates into real capabilities. Today, the initial advantage is not on the American side, and that realization has already had an effect on its military planning. Russia and China have moved first and have forced Washington to accelerate decisions and prioritize resources in the middle of a year of technological validation. It remains to be seen whether the deployment planned for this year consolidates a balance or confirms the gap.

A new study associates late breakfast with lower life expectancy

by

One of the Great statements that has always been done in the field of nutrition is that breakfast is one of the most important meals of the day. Given that premise, we are at a time where The ‘what’ we eat has monopolized our attention counting calories, Analyzing macronutrients and discussing superfoods. However, a new research wave is focusing on an equally crucial question: the “when” we eat. Longevity. One of the great objectives that people have is to last how long the better. But, They tell Putin and Xi Jinping with organ transplantation. But although this is not a viable option, a study that followed almost 3,000 older adults in the United Kingdom for more than three decades is clear that breakfast can be key to calculating our risk of mortality. The key point is the time to have breakfast, which would be a great health marker that points to the much (or little) that can be lived. An internal clock. The field of study that focuses on this aspect of our life is Chrononutritiona discipline that studies our internal clock, what we know as circadian rhythmswhich only dictate when we sleep or wake up, but also regulate our hormones, our metabolism and how we process food. In this way, eating in tune with this internal clock seems to be beneficial, according to researchers, while doing it could disagree our internal machinery. The new studyled by researchers from institutions such as the University of Manchester and Harvard, entered fully into this concept, analyzing how food schedules change as we age and what that means for our health. The late breakfast problem. The researchers analyzed the data of 2,945 adults older than 1983 until 2017. The results in this case were quite clear: as the participants aged, they tended to delay the time of breakfast and dinner, and to shorten their daily “food window”. But what caught the care really was the relationship with the health problems that arise with longevity. Greater mortality. Delaying breakfast associated with a higher risk of mortality in the short term. Specifically, every hour of Breakfast delay It was linked to an 8% increase in the chances of dying, even after adjusting factors such as socioeconomic level or lifestyle. New diseases. In addition to increasing the probability of dying, having breakfast in a late way can be related to a greater burden of physical and psychological diseases, such as fatigue, depression, anxiety and multimorbility, that is, the suffering of several diseases simultaneously. Lower survival. A criterion that can agglutinate the two previous values ​​is the survival of a person. In this case, the analysis identified two groups of patients: on the one hand, those who ate very early and on the other, those who ate later. The researchers could see in these cases that the 10 -year survival rate was remarkably lower in the group that ate later (86.7%), compared to the group that made it earlier (89.5%). The effect of aging. Far from being a simple choice of lifestyle, the study suggests that this change in schedules can be a deeper reflection of healthy health processes. Researchers suggest that genetics play a fundamental role in this case. On the one hand, there is a person who have a genetic predisposition to be ‘nocturnal’ which is what is known as a evening chronotype They have to delay the hours of all their meals. On the other, and perhaps more importantly, the study states that the beginning of a disease can be what leads us to change our schedules, and not vice versa. A conditions such as depression, chronic fatigue or oral health problems can alter appetite and daily routines, causing the first meal of the day to postpone. This phenomenon could be related to what is known as “anorexia of aging”, a geriatric syndrome characterized by the loss of appetite and a lower food intake. A health biomarker. The authors conclude that, rather than being a direct cause of mortality, breakfast time could function as a “simple health marker in older adults.” It is an easy indicator to observe for anyone and that can alert on underlying changes in the physical and mental well -being of a person. This research reinforces the idea that maintaining regular food schedules with our day and night cycle is important to have healthy aging. As they explain from the Harvard School of Public Health, aligning meals with the circadian clock can help regulate metabolism and reduce chronic diseases.

There are dozens of crops with weeks late

by

A few days ago began to circulate online A map in which the distribution of rains could be seen in the last two months. Although I had errorsthe distribution of rainfall was fine and showed a very clear photograph: while Central Europe lived a peculiar drought, in the Peninsula he had not stopped raining. And it’s true. So much so that Aemet itself recognized that the soils of much of the country are saturated. That is, they no longer admit water and all the rain was running directly to the channels. That has been causing problems with the hope that the worst of the situation would happen soon. However, the models point to a new atmospheric block in northern Europe. Is Spain in a situation of receiving more water or all that falls will end up being missing (while destroying everything in its path)? We will not be exaggerating a bit? After all, water is water. We have been complaining about droughtNow that it rains we will also manage them to complain? However, abundant rains are already having a direct impact on the field. It is true that crops such as cereals, vineyards and olive groves have benefited; others instead are In full red alert. A clear example is watermelons and melons. As with Huelva’s strawberries, high rainfall raised moisture levels causing a sudden “proliferation of pests and diseases such as Botrytis (a fungus) or Mildiu“They end up rotting plants. But, little by we stop to analyze it, we see that the problem is greater (because it affects much less striking plants). Let’s talk about the chickpea. 30% of the national chickpea production is concentrated in Seville. Well, as the Secretary General of Coag Sevilla says in The debateat this time “the plant would have to measure a span and still without sowing” because the accumulation of water on the grounds makes it unfeasible. In general, the chickpea has to be more than 100 days in the countryside and “this year, hopefully, will pass 60”. That is turning it into a mousetrap and is making many farmers shuffle to sunflower (up to the limits that the PAC allows). And what will happen? That we probably begin to notice a certain shortage of Spanish chickpea in July. That does not mean that the general prices will rise (those of the native varieades probably yes; but that is inevitable). Most likely, large distributors compensate for local shortages with imports from Mexico and the US – if the commercial war allows it, of course. What if in April the same thing happens in March? Well, the thing is complicated. Between April and May the flowering of many fruit trees occurs. Citrus, for example, moisture It is not very good for them And we already know that the olive tree’s plot asks, above all, tranquility. That is, another month of historical rains would be a problem. Also for the water system in general. Because, although we have Even much storage roomwe are not used to working with the reservoirs, the channels and the full pipes. The final result of more rain would be a waste. What if not? Taking into account that March It has been a historic monthmost likely we do not approach the accumulated of the last weeks. That would force us to make bobbin lace (as in the case of chickpeas), but a good part of the field will depend on the meteorology being consistent and does not “deceive” the plants in their development. Do not forget that March has been The coldest month in three years (in terms of thermal anomaly) and that has disoriented the biological machinery of all plant, animal or thing. In short: the long road to summer begins and we will need a little luck if we do not want this Historical blow of luck become an poisoned candy.

Steve Jobs’s secretary was late for work because of her old car. So Jobs gave him a jaguar

by

Steve Jobs He was not a boss to use And he won the reputation of being an unpredictable and passionate leader. Capable of Inspire and challenge your employees with gestures that moved Between despotism and genius when motivating their workers. One of the anecdotes that best reflect that particular motivation style It happened when his secretary was late for work because his car did not start. There he met a Steve Jobs unpredictablethat it could well have fired her at the act no one would have missed her. However, instead of reproving the delay, Jobs had a most productive idea But, above all, more profitable for the employee. “Take, you never get late” As the Exeuse of Apple Ron Givens said In an interview for WRAL news“People were afraid of him. But that same afternoon, Jobs entered his office, threw him a game of keys of a new jaguar and said: ‘Take, you never arrived late.’ He always did things like that, surprising the people”. He Jobs leadership style was famous for its intensity. He demanded absolute excellence and did not tolerate excuses. “He was able to do surprising things to keep his team focused on Apple’s mission.” For that reason, seeing Jobs waiting for her in her office, she feared the worst outcome. What I didn’t expect was to finish the day with A new jaguar In his garage. Apple’s former director assured that the secretary “was a single mother and a good secretary”, pointing out the good performance of the Jobs employee. Perhaps that good performance was what made Steve Jobs, very in favor of surrounding himself with brilliant professionals, did not get carried away by his impulses and chose to eliminate the problem he had prevented (and would probably come back in the future) to his secretary Reach timely to your workplace. Jobs’ unpredictable motivation Andy Hertzfeld, one of the original Macintosh engineers, assured That working with Steve Jobs was unpredictable: scary and exciting at the same time. Givens corroborated him in his interview, in which he acknowledged that Jobs was an “excellent motivator” and “a good leader”, that as soon as he could say goodbye to a wrong response, like rewarding you with a luxury car. Actually, Jobs’s approach by giving his secretary a jaguar was not a mere gesture of generosity. Apple’s CEO demanded maximum motivation And dedication to their employees, so eliminating those concerns that prevented them from giving 100% of their potential was just a way to get both with a single gesture. Today, the figure of Steve Jobs remains a reference both in technology and in the Business management. His methods could be questionable, but Its impact on industry It is unquestionable. And that secretary who received a new jaguar is just one of the many evidence that, with Jobs, he never knew what to expect.
