CRASH Clock is the proof

by

Low Earth orbit is increasingly close to becoming the new space M-30. Every year more satellites are launched and the risk of collisions that end in catastrophe grows exponentially. We can see it in a much more indicative way thanks to a new indicator called CRASH Clock (Collision and Significant Damage Watch). This indicator warns that only 2.8 days would separate the current moment from a serious collision if we were suddenly left without evasion maneuvering systems. The abysmal difference compared to 2018. A team of researchers led by Professor Sam Lawler, from the University of Regina, Canada, has developed this indicator to measure the increasing risk of collision in low Earth orbit (LEO). The CRASH Clock is not a countdown to Kessler syndrome (that theoretical scenario where collisions generate exponential cascades of space debris), but it does reflect how congested orbital space is and how quickly everything could get worse in the event of any failure in the prevention systems. The most worrying fact: in 2018, before the massive deployment of mega satellite constellations, that same clock showed 121 days. In just seven years we have gone from four months of margin to less than three days. Why does it matter now?. The density of objects in LEO has skyrocketed with the arrival of megaconstellations. starlinkthe SpaceX satellite network, is the most visible example. According to a report filed with the United States Federal Communications Commission (FCC), its second-generation satellites perform an average of 44 evasion maneuvers per year. Researchers have calculated that this is equivalent to one maneuver every 1.8 minutes across the entire constellation. “There’s no magic here, you’re just avoiding collisions by moving a Starlink satellite every two minutes. This is bad,” counted Lawler in a Mastodon thread. Graph showing the probabilities of a catastrophic collision if the avoidance maneuvering systems were to fail In the densest area of ​​LEO, currently occupied by Starlink, approaches of less than a kilometer occur every 15 minutes. It may seem like a safe distance until you remember that these objects travel at seven kilometers per second. We depend on technological perfection. The system works… for now. SpaceX applies an extraordinarily conservative maneuver threshold: its satellites take evasive action when the probability of collision exceeds 3 in 10 million, well below the industry standard of 1 in 10,000. But this efficiency comes at a price: an absolute dependence on automatic systems continuing to operate without failure. The real danger is not in everyday life, but in unexpected events. A major solar storm, a widespread software glitch, or simply a miscalculation could trigger chain collisions. The study’s authors warn that we are currently “well within the Caution Zone,” with a greater than 10% chance of collisions occurring in any 24-hour period if avoidance maneuvers were to cease. What the simulations reveal. The researchers used two methods to verify their calculations: analytical analyzes with data from public catalogs and simulations of bodies in orbit. In one of the simulations, by pure chance, the first collision occurred just three hours after the hypothetical cessation of the maneuvers. Before megaconstellations, the densest part of the orbit experienced a closer approach of less than a kilometer a little more than once a day. Now it happens more than once every 15 minutes. International coordination, key. Beyond Starlink, other megaconstellations are in the launch phase. OneWeb, Chinese projects, future Amazon deployments… they will all share the same orbital space. Therefore, communication between all agencies, governments and institutions is essential. But of course, “will China talk to Starlink?”, “will the secret satellites of the United States Government talk to OneWeb?” are questions that Lawler reveals. Beyond collisions. The risks are not limited to collisions between objects. The study also points out problems already present: astronomy disruption observational, pollution in the atmosphereand increased risks of casualties on land. “From these safety and pollution metrics, it is clear that we have already put LEO under substantial stress, and changes to our approach are required immediately,” the paper’s authors conclude. What’s coming now. The team has created a website where to periodically update the CRASH Clock and keep this alert visible. It is not about catastrophism, they clarify, but about ‘situational awareness’. “In the short term, a major collision would look more like the Exxon Valdez tanker disaster than an immediate end to Hollywood-style orbital operations. Satellite operations could continue, but with different operating parameters and a higher risk of collision damage,” counted Lawler.

It’s tempting to start a “miracle diet” against the clock to get to Christmas. The experts have something to say

by

We have reached December and, with it, Christmas lights turn on and also a silent race that repeats itself every year. While company dinners, meetings with friends and family gatherings accumulate, thousands of people begin what we could call “the last sprint”: losing weight quickly before sitting down at the table at Christmas. But behind this sprint There is a much more complex phenomenon. One that has social, emotional and biological roots, and that hides a perverse effect. Express diets teach the body to be more efficient in saving energy, which ends up causing us to regain it and sometimes even more after losing weight quickly. The pre-Christmas sprint. Every December, an almost automatic reflex is activated, the feeling of having to “get there safely” to the holidays. The psychologist specialized in Eating Disorders (ED), Sara Bolo, He explained to us in Xataka that this phenomenon is not coincidental, but a pattern that repeats itself year after year. “Christmas is a special time, where we see family or friends again that we don’t see every day. And with that, comments about the body reappear: ‘I look thinner at you’, ‘you’ve gained weight’…” This dynamic, as common as it is harmful, multiplies aesthetic pressure and turns coexistence into a silent body examination. Another ingredient is added to this context, the purposes that were not fulfilled. “We arrived in December with the idea of New Year, New Me that we announced in January – says Bolo – and the urgency appears to show that we have achieved something.” That mixture of self-demand and closure of the cycle pushes many people to make drastic decisions in a very short time. One more factor. And it’s not just aesthetic pressure or frustration, there’s also anticipatory fear. According to Bolo, it is common for some people to restrict their diet in the weeks before, thinking that this way they “compensate” for Christmas meals in advance. “It becomes a defensive preparation. I don’t want them to tell me anything, I don’t want to feel guilty, so I start restricting before,” he details. This urgency is exactly what dietitian-nutritionist Laura Jorge also observes, director of the centers that bear her name. Since your consultation, December always has the same profile, more requests for “quick fixes”, more promises of express weight loss and more anxiety. “Every year we see an increase in people looking to lose X kilos ‘before the holidays’. It is a very clear pattern,” he explained to us in an interview. Three elements are repeated: urgency, guilt and dichotomous thinking – “now I restrict myself, and at Christmas I will eat” -. What starts as a sprintBoth experts agree, it usually ends up being an emotional and metabolic trap. The hidden enemy. Science explains it bluntly, when we subject the body to extreme and sudden caloric restriction, the body activates survival mechanisms, not weight loss. As Jorge details, the metabolism slows down, hunger increases, satiety decreases and the body begins to use muscle mass as a source of energy. This not only makes it difficult to maintain weight loss, but also reduces basal metabolic expenditure, making it easier for us to gain weight later. Scientific research supports these observations. A study of New England Journal of Medicine showed thatafter losing weight, leptin—the satiety hormone—was still low and ghrelin—the hunger hormone—was still elevated even 12 months later, even though the person had already recovered part of their eating routine. The authors conclude that these adaptations create “a physiological environment that favors the recovery of what was lost.” In addition, the factor of genetics must be taken into account. A study from 2024 published in International Journal of Obesity points out that not everyone responds the same; some people, after repeated cycles, develop a greater risk of insulin resistance or visceral adiposity. The other side. Rapid weight loss has an immediate emotional effect and makes it seem like a success. “You get on the scale, you see fewer kilos and you feel immediate euphoria,” admits Sara Bolo. But it is a mirage. When the weight returns – as it usually does – the emotional collapse appears: guilt, frustration, shame, absolute thoughts (“I am a failure”, “I have no willpower”). Furthermore, the environment reinforces this dynamic because thinness is praised and gain is censored, even with “innocent” comments. This back and forth deteriorates self-esteem and fuels restrictive behaviors that, far from solving the problem, intensify it. A door that is better not to open. “The restrictive diet is the first step of any eating disorder,” he says. the psychologist Rigid control, obsessive calorie counting, avoiding social meals, or classifying foods as good or bad are early signs. And Christmas is one of the moments where they manifest themselves the most. Laura Jorge agrees: “In these weeks we see people who begin to talk obsessively about compensating, skipping meals or doing compulsive exercise. These are signs that should not be ignored.” The combination of aesthetic pressure, abundance of stimuli and comments can activate a latent ED or aggravate an existing one. When the comment is “innocent”, it is not. Social responsibility is evident. The experts remember that comments as common as: “Oops, are you repeating yourself already?” “That’s good, you’re thinner.” “After these meals, tomorrow on a diet.” Behind all these phrases, a thin laugh follows that for many sounds like a roar. And as experts say, they are not only unnecessary, but potentially harmful. “You have to take care of your language,” summarizes the nutritionist. “Do not congratulate people for losing weight, do not comment on their own or other people’s bodies, do not pressure them to eat or stop eating.” Aesthetic pressure often begins with a comment that seemed harmless. So how can we accompany? For those who live Christmas meals with fear of losing control, the key is not in the plate, but in the environment. The psychologist Sara Bolo insists that accompany It does not mean guarding, but offering a safe space. His advice … Read more

The best Apple wins and battery clock in addition to release 5G

The Apple Watch Ultra renews itself after two years of waiting. Apple has presented the Apple Watch Ultra 3the third generation of its most resistant and advanced smart watch, aimed at athletes and adventurers, or simply watch enthusiasts looking for the model with the best possible specifications. As expected, the company maintains its focus on extreme durability while introducing improvements in connectivity and performance. The great novelty comes with a larger screen, satellite connectivity and 5G support for the first time in an Apple Watch. These are the characteristics that consolidate Ultra 3 as the most complete Apple watch.

The chip in principle maintains the architecture of 64 double -core bits with four -core Neural Engine that we already know. The big difference is in the new capabilities that it unlocked, especially in connectivity and health data processing. Later we can give more details about this chip. Satellite connectivity: Never again without coverage The most revolutionary incorporation of ultra 3 is its satellite connectivitymaking the clock the first Apple capable of working completely without telephone towers. This technology allows to send emergency messages and contact rescue services from anywhere on the planet, such as what was seen on the iPhone of recent years. Complementing this novelty, ultra 3 is also the First Apple Watch with 5g supportthanks to a modem that significantly improves connection speeds in areas with 5G coverage. Apple introduces for the first time Hypertension notifications In Ultra 3, expanding the health capacities of the device. This function adds to the renovated SPO2 detection system, which is officially back after legal problems in the United States during the last year. Image: Apple. Besides, lto new waypoint sphere It shows points of interest dynamically depending on your location. The exclusive spheres of the Ultra, like this, are also one of the arguments of sale of this model against the series or the SE. As in the Series 11the ultra 3 premieres new details in sleep monitoring. Now you score each session based on the total duration and duration of each phase, something that makes sleep quality more easier for one night, going more in detail than simple duration.

Fix your work schedules looking at the clock instead of the thermometer

by

I leave home at 4:00 p.m. and, armed with value, I go to pick up the car from the mechanic. It has ended with him and Previous reviews They have the collapsed workshop, so he asked me to pick it up as soon as possible. On the portal, I cross a neighbor who enters the stifled street, with his forehead peeled by droplets of sweat and defeated attitude, as if he had loaded a heavy slab. “It’s hot?” – I tell him knowing already an answer, “he has always been hot in summer, but this is hell,” he replies. “Who comes up to the street with the heat it does,” I say while I open the door of the portal and take a step back remembering the apocalyptic vision of Sarah Connor Abrasada by nuclear flames in ‘Terminator ‘. Has always been hot in summer According to The data Aemet, it is true that as my neighbor had told me, has always been hot in summer…But not so much. The temperatures recorded in recent weeks leave last June as The warmest of the historical seriesand joins the long list of records of extraordinarily warm months. NASA itself He supported with data that they are now warmer than those of yesteryear, taking into account that their records date back to 1880. In addition, these heat episodes are increasingly frequent because summers are increasingly long. On average, it is estimated that the climatological summer has been stretching between four and fifteen days per decade. Our grandparents adapted While it is true that Spain has always been a country with hot summers, there is a factor that we should not overlook: today We do not face the rigors of heat as our grandparents didbecause we We do not change our working days depending on the temperature as they did. When I was a child, my grandfather told me that “in her young years”, it came out before the field was made to work the earth “with the fresh” before the slab of the heat of the Andalusian countryside fell on the day laborers. At noon, when the sun tightened, they sat down under a chaparro (oak) to eat in the shade and then nap until early in the afternoon. Then, they went to the farmhouse in which he worked and performed there other tasks of cleaning, maintenance and care of animals until the end of the day. ALWAYS TO THE SUN CAKE. In winter they usually did the other way around and reached the field when the frost had dissolved. That is, they took advantage of the first rays of light to perform the toughest agricultural tasks to avoid high temperatures and rigor of the sun in the hours of greater insolation. As much as it was the mowing, harvesting or planting season, they tried to avoid the central hours of the day, and instead, they advanced or delayed their working days to adapt to the weather. There was no one closed and strict schedule For the whole year. On the other hand, at present, the Adaptation of the tasks and working days It is minimal and the schedules have been standardized. It doesn’t matter if it is an office, mason or mailbox work, and it is not taken into account whether on the street it is freezing or mercury marks the 46 ºC. The schedule is the same for everyone throughout the year. Heat -inflected hours This standardization of schedules makes it normal for an employee of the Municipal Maintenance Service, one of the groups that most work accidents and Deaths due to heat blows has suffered In recent daysbe cleaning the sidewalks at two o’clock in the afternoon in full wave of heat, or that an installer is placing a label on a facade at three. According to data from the Carlos III Health Institute facilitated By the National Institute for Work and Health at Labor (INST), it ensures that per year there are about 1,300 deaths attributable to heat. Around 4% of fatal accidents that occur in the workplace are caused by heat blows due to prolonged exposure at extreme temperatures. The most exposed professions are those that cannot develop their main outdoor activity: agricultural sector, cleaning operators and public works, assemblers, construction workers or gardeners. Thermal stress also affects professions that develop indoors that due to the nature of work, they are exposed to machinery or heat sources such as industries, hospitality, laundry, greenhouses, etc. Andalusia, Catalonia, Madrid, Aragon and Galicia They are located At the head in terms of mortality due to heat, coinciding in many of those cases with personnel used in the sectors that we have mentioned before. Unlike our grandparents, these sectors now have fixed schedules that, in many cases, develop between 8 in the morning and 18 hours, leaving them exposed to work during those hours that our grandparents tried to avoid at all costs. The tools are there Approval in 2023 of Royal Decree Law 4/2023 He came to make the adaptation of schedules and tasks that already enjoyed our grandparents, so that companies, rather than look at the clock, must look at the thermometer to design the working days of their employees during extreme heat episodes. The Occupational Risk Prevention Law It offers companies to modify schedules and even cut the working days during these heat episodes to protect their employees. In addition, following the Dana that razed Valenciathe Law was extended Adding the possibility of having a four -day paid permission when, in extreme cases, the working day cannot be adapted and it is impossible to carry it out without exposing itself to a real health risk. The last modification also contemplates the possibility that companies can benefit from a climate ERTE. “No one has to take risks,” insist From the ministry. However, despite the tools that allow companies Protect the health of your employeesthe National Institute for Safety and Health at work ensures that occupational accidents during heat waves … Read more

Europe has started a race against the clock. And China has entered to make prices more expensive

by

Winter has left Europe with reservations practically empty and needs to reach a level of 90% before November. Meanwhile, China has emerged as a direct competitor in the global gas market, putting Europe in a counterreloj race to guarantee its supply before prices shoot. Short. The European Union will have to spend 10,000 million euros more than last year to fill its gas reserves, According to the Financial Times medium. The reason behind this increase is due to a colder winter, an increase in demand for less renewable generation and greater dependence on liquefied natural gas. The background. It all started with the war in Ukraine, since until that moment Russia supplied about 40% of the gas To the EU. However, commercial reprisals and sanctions drastically reduced that supply, to the point that an agreement has been signed to fully close exports in 2027, According to Euronews. A vicious circle. The European bloc had to look for other alternatives, such as the GNL imported from the United States and Qatar. However, it continued to supply Russian gas Through third countries or by calls “Ghost ships”. At the same time, the European Union was trapped in a price instability cycle, caused in part by the spot market dependence for LNG purchases. As He explained The London medium, this situation caused governments to compete with each other to ensure cargoes, inflating prices and generating distortions in the market. Flexibility in storage. Given the difficulties in maintaining 90 %reserves, the European Commission is considering granting greater flexibility in the storage objective, especially after Germany – the country more dependent on gas – requested adjustments to avoid price peaks in summer. However, in parallel, Germany has reached an agreement with France to receive energy support through the nuclear energy supply. A strategic movement that seeks to ensure its energy stability while storing objectives are readjusted. This measure aims to relieve pressure on markets, although it generates uncertainty due to the possibility that changes are not promulgated in time. The recharge dilemma. According to Kuhanathan, an analyst from Allianz Trade, has declared Financial Times That many gas merchants are delaying reservation recharge, waiting for prices to fall further. However, this attitude could generate a sharp increase in demand at the end of summer, shooting prices just before winter. In addition, Peder Bjorland, Vice President of Equinor Gas Commerce, has warned in the same medium that Europe will have to pay higher prices to overcome Asian competition if China’s demand is replenished. China, a determining factor. The largest world buyer of liquefied natural gas is China. Last year, LNG’s Chinese demand was reduced due to an unusually favorable climate and economic slowdown. This drop in consumption allowed Europe to access cargoes that, otherwise, would have gone to Asia, contributing to stabilize prices in the short term. However, projections for the coming months indicate a possible rebound in Asian demand. The commercial truce between Beijing and Washington, Recently announcedcould activate an increase in Chinese industrial activity, which would raise the demand for LNG, According to estimates of the Financial Times. In addition, a hot summer in Asia can further increase gas consumption, putting Europe in a direct competition situation with Asian buyers. According to Morgan Stanley analysts for the same medium, this additional pressure would boost gas prices up to 10%. A decisive actor. During the commercial war with the United States, Beijing He hinted that he could sell American liquefied natural gas to Europe, but the situation has taken a totally different nuance. Now it is key to observe The development of the Power of Siberia 2 gas pipeline With Russia, as well as China’s ability to DNA. Leaving the framework of the global energy future open.

The latest creation of the productivity guru is not a new method, but a clock that counts the days that are missing to die

by

A little over a year ago, in Xataka We talk about ‘second brain‘, that concept popularized by the productivity guru Tiago Forte. His latest novelty is not another book or other method, but A tool as simple as disturbing: Death Clocka calculator that predicts with mathematical precision the date of your death based on 17 custom variables. The calculator tells you, after answering some questions about your life habits, the exact day in which you are expected to die. And although it sounds a bit macabre and childish, the idea makes sense. Obviously, it is not an exact prediction or intends to be. It is rather a Mori memento digitala modern way of practicing that old philosophical exercise of contemplating our mortality to live better. The application simply translates your habits into a longevity estimate: changes from “sedentary” to “intense daily exercise” and you will see how a decade of life instantly wants. A numerical visualization of how our daily decisions accumulate over time. The first questions of the questionnaire. Click on the image to go directly to the application. Image: Death Clock. And a technological curiosity: Forte does not know how to program, so he built the entire application in a few hours by resorting to the VIBECODING With ia. He basically told a programming assistant what he wanted and this was creating the code for him. What really matters is how your perspective changes knowing that you have already exhausted, for example, 40% of your life. Suddenly, that meeting that could have been resolved with an emailthat mediocre series that you are seeing by inertia or that project that you carry postponing for years take a completely different weight. It’s not about being morbid or depressed thinking about the end. Not even giving more importance than what it simply puts figures to what we should intuit. Simply becoming aware of our finitude helps us to filter the noise and focus on what we really want to do with the limited time we have. It forces us to ask ourselves if this is what I want to spend one of the days I have left. And maybe there is the key to productivity. Not to do more things, but to do the right ones. Those that really matter. In Xataka | The “Johari Window”: understand how others see us unlock a good part of our potential Outstanding image | Xataka with Mockuuuups Studio

What if the constants of the universe are not so constant? We have taken an important step to know. The key is on the nuclear clock

by

Atomic watches have meant a before and after in our ability to measure time in an outraged way. These types of watches are precise at such a level that some of the most exact ones would be discouraged in less than a second at the time in which the universe has been existing. Despite this, these watches are not precise enough to solve one of the most important unknowns in physics. Closer to the nuclear clock. Now, however, we are a little closer to achieving a milestone that can open the door to solve this type of doubts, Nuclear watches. These watches will allow us to advance several orders of magnitude in the creation of time measurement apparatus, ultra -precise watches to investigate the new physics. From atomic to nuclear. The nomenclature can lead to confusion, and when we talk about atomic watches and nuclear watches we are not talking about the same technology. While the mechanism of atomic watches depends on the state of excitation of the atom electrons; in the Nuclear watchesthis depends on the particles in nucleus. As its name indicates. Atomic watches depend on the transitions in the state of their electrons. When they absorb energy, they can “jump” in their state. Jumps that can be reversed, only when this occurs, it is the electron that emits energy in the form of electromagnetic radiation. Something similar occurs in the nucleus of atoms, only that, being the most isolated nucleus of other physical interactions external to the atom, the transitions of their subatomic particles would be even more precise and reliable than those that occur in the atomic “shell” formed by electrons. Torio-229. To make a nuclear clock work, we also need to transfer energy to the atom, to its nucleus, of course. When we hit the nucleus with a specific frequency of electromagnetic radiation, we can change its energy state, as if it were a switch. Nuclear watches, such as atomic, would only have to tell the energy changes in this context. The problem is that causing these jumps in the atomic nucleus is also more difficult. The main difficulty is to excite atomic nuclei enough to cause the “jumps.” To do this we must hit these coherent X -rays nuclei, a high frequency X -ray type and therefore high energy. So much that, in general we do not have the necessary instruments to produce them. “In general”. And, as with electrons, not all these “jumps” require the same energy. Almost half a century ago, researchers realized that the isotope atomic nuclei Torio-229 (229th) It had a jump that required the energy equivalent to that of ultraviolet light. When requiring less energy, building a laser capable of transferring energy to the nucleus, it became Something feasible. Half a century of work. The “Nuclear Transition” of Torio It was discovered in 1976. But that was just the beginning. And it would not be until 2016 that we would observe and measure it. Measure it is key, since if we want to force the transition we must know the exact frequency with which we have to “bombard” the atomic nucleus of this isotope to be able to force it and activate the process. How close are we really? A few months ago, a group of researchers He tested Some of the key elements behind this technology, which allows us to get an idea of ​​how close we are to be able to create a nuclear clock based on 229th. The team tested an ultraviolet laser capable of creating precise energy to force jumps in the state of the nucleus. He also studied a “frequency grid” to directly measure these jumps. In addition, they also studied the transition from Torio-229. The details of the study were Published in an article In the magazine Nature. From dark matter to universal constants. And all this for what? Do we really need more precise watches than atomic? The truth is that this new technology would have important benefits, first for the scientific community, but also for all citizens. These watches They can help us to improve technologies such as GPS and other navigation systems; And also global Internet synchronization, also making the connection faster and safer communications. We would also open the door to more precise measurements that help us clarify some of the mysteries that persecute physicists such as dark matter. Maybe more importantly, these watches could help us develop experiments that resolve One of the most important doubts of physics, the one of universal constants They are really constant And they do not change depending on factors such as the age of the universe or the frame of reference in which we find ourselves, as we until now assumed.
