The Council of Ministers has given green light to a key reform that will allow those who work in professions cataloged as especially dangerous or painful retire before usual. The Minister of Inclusion, Social Security and Migrations, Elma Saiz, stressed that this reform “brings us closer to policies approved by European environmental countries, such as France, Austria or Italy, but above all it is a step forward in social justice.” The objective is clear: to offer an exit from the worthy work world to those who exercise Professions with high accident rates and occupational diseases such as firefighters, miners, height workers, police or flight personnel. Retirees at 52 years. The government has A procedure approved to establish reducing coefficients that allow anticipating retirement age for those who perform activities considered “exceptionally painful, toxic, dangerous or unhealthy” and present “high rates of morbidity or mortality.” Thus, the approval of early retirement applications is extended to unions that until now were not included in the professions list painful and high risk. Among the objective criteria to identify these professions include exposure to noise, permanent use of physical strength, contact with chemical or biological agents and the high probability of suffering work accidents. However, the Royal approved decree It does not specify what professions affect, delegating to social security, employers and unions the task of specifying the specific casuistry of each guild. Requirements to retire in advance. To access this early retirement, maintaining 100% of the retirement pension, workers must prove that they have performed these activities for a minimum time of 15 years and exercise it at the time of requesting the early retirement. The minimum retirement age, even applying these coefficients, may not be less than 52 years, and it will not be possible Active retirement in the same work activity that gave access to retirement. Retirement for other employees. The Law 27/2011 It establishes the terms of the progressive increase in the retirement age in Spain and the quotation time. In 2025, the Ordinary retirement age in Spain It is 66 years and 6 months for those who have quoted less than 38 years, while those who have contributed 38 years and three months can request ordinary retirement at age 65. With the new measure approved by the Government, those who request to retire at age 52 will be computed the remaining years up to 65 years as quoted, so that they are not applied reducing percentages to their pension. Voluntary early retirement. For those who wish to retire in advance without belonging to the recognized risk groups, the law contemplates a significant reduction in the pension. In 2025, the penalty can reach up to 21% of the pension amount if the permitted retirement is advanced, which is 24 months before the ordinary age. That is, a minimum age of 63 years is established to request it. This penalty applies progressively and depends both on the advance time and the quoted years. Social security calculates the cut by applying reducing coefficients for each quarter or month of advance with respect to the legal retirement age. This measure aims to discourage early retirement generalized and guarantee the viability of the public pension system.

We have discovered a relationship between olive oil and risk of death by dementia, a point in favor of the Mediterranean diet

by

Someone could think that everything is already said, all investigated, on one of the fundamental axes of the Mediterranean diet, olive oil. Nothing is further from reality: research on this food continues and continues to reveal striking aspects of the liquid. And as regards striking relationships, perhaps the palm is taken by the fact that they keep the consumption of this derivative of the olive and dementia. 28%. A study published a few months ago established existence of this relationship. Specifically, the analysis responsible for the analysis observed a 28% reduction in the risk of death associated with dementia between people who consumed at least Seven grams of olive oil per day, compared to those who did not consume this liquid or did it rarely. Until now, some studies They had indicated us an inverse relationship between the Mediterranean diet and the cognitive deterioration associated with age. From there, establishing relationships between different aspects of these variables can help us better understand the link between Mediterranean diet and healthier aging. Changing ingredients. In its analysis, the team also studied the effects of replacing different sources of fat. Through a substitution modeling, they estimated that replacing five grams of margarine or mayonnaise daily with an equivalent amount of olive oil could be related to a decrease in the risk of mortality associated with the dementia of between 8% and 14%. A similar analysis did not detect similar effects when these fats were replaced by other vegetable oils or butter. 92,383 participants. The study was conducted from the macro -conformation Nurses’ Health Study II and Health Professionals Follow-Upwhich allowed to obtain Information about 92,383 participants. These filled surveys on eating habits every four years over a 28 -year period. The team divided these participants depending on their olive oil consumption: those who never consumed olive oil or did it less than once a month; who consumed up to 1.5 grams per day, who consumed between 4.6 and 7 grams per day; and a group for those who consumed more. The team extended its analysis over 18 years of the study and controlled aspects such as the general quality of the diet or the genetic predisposition to suffer from the disease. The details of the study were published In an article In the magazine Jama Network Open. What is happening? When establishing a causal relationship, it is always convenient to understand what mechanisms are operating behind this relationship between olive oil consumption and death risk associated with dementia. “Olive oil is rich in monounsaturated fats and contains components with antioxidant activity that can play a protective role for the brain,” He explained to the environment UPI Anne-Julie Tessier, co-author of the study.

a month to present changes to their “false discounts” or risk fines

by

The relief that Shein has achieved in the United States thanks to the Temporary Tariff reduction Contrast with the new front that opens in Europe. The European Commission and the Cooperation Network for Consumer Protection (CPC), which brings together the national authorities of the Member States, They have notified to the electronic commerce platform that several of its practices vulnea community legislation. Now he has a month to respond and avoid possible coercive measures. According to the official statement of the commissionThe notification is the result of an investigation coordinated by the authorities of Belgium, France, Ireland and the Netherlands. The CPC network It accuses Shein of applying tactics that directly affect consumer rights within the single market. What practices Brussels questions The file open to Shein lists a series of infractions related to the way in which its platform operates and communicates commercial information to consumers: False discounts: Price reductions that are not based on real prices are shown. Pressure tactics to buy: Use of techniques to push the user to finish the purchase. Lack of information or deceptive data: On the legal rights of return and reimbursement, or the way in which they are managed. Deceptive labels: products that appear to have special characteristics when in reality these are minimal legal requirements. Doubtive sustainability promises: Incomplete or false information about the environmental benefits of certain products. Contact difficulties: absence of clear and accessible channels to raise doubts or claims. Brussels is not limited to an informal warning. The notification requires concrete commitments. If in the next 30 days Shein does not respond properly, the national authorities may apply sanctions. Among them, the possibility of imposing fines proportional to its volume of business in each affected country is contemplated. This procedure adds to the ongoing investigation that the Commission itself maintains under the Digital Services Law (DSA). Shein was designated in April 2024 as a “Very large online platform”(Vlop, Vary Large Online Platform), which forces it to meet the strictest requirements in systemic risks, illegal content control and algorithmic transparency. The pressure not only comes from Brussels. Italy’s competence authority has started a procedurealso focused on the company’s commercial practices. In parallel, the Commission has made it clear that these actions do not interfere or limit other possible measures under product safety or data protection. In response to notification, a Shein spokesman declared the Wall Street Journal that The company is actively cooperating with the authorities. “Our priority remains to ensure that European consumers can enjoy an online purchase experience safe, reliable and pleasant”, Said. Shein, as we say, now has 30 days to present his commitments.

Volvo has equipped its electric SUV with a very potent lidar. So much that the risk of frying the camera of your mobile is real

by

Volvo has among its ranks a SUV up to technology, the Ex90. Presented in 2023, it is the electrical alternative to the classic XC90, presuming systems such as the Autonomous Level 3 SAE driving or the equipment of a radar Lidar to detect elements of your environment. What perhaps they had not told you is that, precisely, the lidar sensors of greater capabilities are the archNiene of our usual partner: the smartphone. You can leave you the fried camera. Volvo warns him in his own Support page: Lidar light waves can damage external cameras. The technical explanation is brief, but the message is clear. “Do not point a camera directly when Lidar. Lidar, being a laser -based system, uses infrared light waves that can cause damage to certain camera devices. This can include smartphones or phones equipped with a camera.” Although it sounds like a warning, perhaps something alarming, there are already those who have shown in real time how a lidar can instantly disintegrate the pixels of a mobile sensor. They are not color. They are supposedly fried pixels after burning when aiming at a lidar. The lucky one. In Volvo’s subform in Reddit A video has been viralized in which it can be seen how, when recording the lidar of this electric car, the sensor pixels are gradually burned. Reddit is Reddit and no one can ensure the authenticity of the video, but if we understand the theory behind that a lidar can disintegrate a camera, all the pieces begin to fit perfectly. Your camera sensor. Smartphones use sensors that not only capture visible light (spectrum of 380 to 750 Nm), they are also especially sensitive to near infrared (750 to 1100 nm). In fact, they usually come equipped with an infrared cutting filter in charge of mitigating this light and preventing it from affecting the final result. These filters usually block most infrared light, but they are not perfect. An easy test to do at home is to aim with a TV command to the camera of your mobile. That purple flash that you see is proof that smartphones cameras let infrared light. Destroying pixels. The infrared light emitted by a command has barely power, is emitted in a standard frequency of between 850 and 950 nanometers. What happens to the Lidar del Volvo Ex90? That emits pulsed lasers of 1550 nma wavelength in the middle infrared. This is still invisible to the human eye, but it is a considerable power. If a lidar laser with enough power points directly to a CMOS sensor, it can end up saturating the pixels of it. In other words, it can cause permanent damage and load the pixels that have received their emission of light. A phenomenon studied. Although the Lidar del Volvo Ex90 has put this problem on the table, this is a problem that we have been dragging for more than 20 years. In 2004, studies such as “Lase-Induced Damage Thresholds in Cmos and CCD Sensors ” The destruction of both individual pixels and complete columns after being exposed to compact laser systems was shown. It was highlighted how in wavelengths between 800 and 1,600 Nm (just the latter is the one that caresses Volvo), the damage is irreversible and there is no possible physical defense for infrared protection filters. Lidar in the Volvo Ex90 Volvo is not the only one who warns. Smartphones are not the only devices in using CMOS sensors: the vast majority of consumption miral cameras use this technology. Any manual warnsbefore even starting to explain how the camera works, not directly notice with a laser to the sensor. “When you make Tomas backwards, keep the sun sufficiently far from the viewing angle. Always maintain intense light sources, such as sun, laser or artificial light sources, outside and far from the image area. The concentrated strong light could produce smoke or damage the image sensor or other internal components.” At the moment, Volvo is one of the few companies that, together with Luminar (the company behind its Lidar technology) has detailed the emission of laser pulses in this type of radars. It is expected, however, with the democratization of the Lidar (especially in future cars that will come from China), we have to get used to these power figures.

Nvidia is tensing her relationship with the US government. His presence in China is at risk

by

For Nvidia losing the Chinese market is not an option. During the last fiscal year, which expired on January 26, 2025, China represented approximately 13% of total income of the company led by Jensen Huang with a figure of some 17,000 million dollars. In practice, the country governed by Xi Jinping is the third best client of this company only behind the US and Taiwan. However, the sanctions to China that are deploying the US government threatens Nvidia’s survival in this Asian country. Currently this company cannot sell its chips to its Chinese clients to artificial intelligence (IA) more advanced. And in the middle of last April the US Department of Commerce imposed new export restrictions on China from The H20 GPU of Nvidia. The tuning of a trimmed review of the H20 GPU is underway The reception they have given to the GPU H20 The Chinese clients of Nvidia has been very good despite the fact that the capabilities of this chip are clearly lower than those of the other proposals for the this company. In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations its sales in China 50% quarter to quarter have grown Since he arrived in this market in mid -2024. The Nvidia Plan requires a cut review of the H20 GPU that satisfies the restrictions imposed by the US Department of Commerce Anyway, this time of bonanza is over. The restrictions of the Department of Commerce in practice prevent Nvidia Deliver the H20 GPU to its Chinese clientsbut this company does not give up. At the beginning of this week We explain to you that several reliable media had collected that His engineers are working on new GPU for AI expressly adapted to the country’s market led by Xi Jinping. Now we know something else. And is that according to Reuters The Nvidia Plan requires tuning a trimmed review of the H20 GPU that satisfies the restrictions imposed by the US Department of Commerce. The surprising thing is that this project seeks to cut a chip that is already a cut version of other NVIDIA GPUs. And it is not clear that with this limited benefits this trimmed GPU H20 is interesting for companies that have bought the original H20 chip from NVIDIA. Among them are no less than three giants from China: Alibaba, Tencent and Bytedance. However, Nvidia faces one more challenge: Huawei’s competition. And this last company is reinforcing its position in China to take advantage of the hole that Nvidia is leaving in the market because of US sanctions. During the second half of 2025 will manufacture the GPU Ascend 920 on a large scalewhich is clearly destined to occupy in the Chinese market the gaps that the GPU H20 is going to leave. And, in addition, it is about to start the chip test phase Ascend 910dwho seeks to overcome the performance of the chip NVIDIA H100.

We have been reading about the danger of arsenic in rice for years. So much that we run the risk of not believing it in the worst possible time

by

Arsenic is one of the best known toxic elements. The fact that traces of this element can be found in the rice we consume sounds more alarming than it really is: today only very high consumption of this food could involve health risks. The problem is that this can change in the future. Growing concentrations. A new study has pointed out that the increase in temperatures and carbon dioxide concentrations (CO2) in the atmosphere can favor the absorption of arsenic in rice crops. This would translate into a greater presence of the element in the dishes elaborated from this cereal. A change whose impact could be significant around 2050. This increase in arsenic concentration could especially affect the population in Asia, where rice represents a higher portion of the food consumed. “Our results suggest that this increase in arsenic levels could significantly raise the incidence of heart disease, diabetes, and (cause) other non -carcinogenic effects,” he said In a press release Lewis Ziskka, co -author of the study. The risk of arsenic. Arsenic is considered a heavy metal despite chemically belonging to the semimetal group. He Risk level which implies its presence depends on several factors, for example on the fact of the molecular structure in which it occurs (its organic structures are less dangerous than the inorganic ones). And, of course, it depends on the dose. The risk posed by this element has to do with its accumulation in our body. Its presence can lead to problems in development among the youngest, and in adults it has been related to skin disorders, bladder and cancer of lung. 28 Rice varieties. The team responsible for the study analyzed the effects on the rice of an average increase of 2º Celsius at the temperature and the associated increase of atmospheric CO2. Did it in 28 varieties of this cereal, modeling the evolution of its inorganic arsenic content over 10 years. From there, the team estimated the health impacts that this accumulation could produce in the populations of seven Asian countries around 2050. The result: a drastic increase in cancer cases and especially the cases of bladder cancer. Among the countries studied, China would stand out, which could see more than 13 million new cases of cancer associated with arsenic exposure. The details of the study were published In an article In the magazine The Lancet Planetary Health. Not everything is lost. In its study, the team raises some possible adaptation measures dedicated to reducing the future impacts of this problem. The team suggests hybridar varieties of plants to favor those that absorb less, introduce improvements in soil management in rice fields, and improve food processing practices. They also propose consumer -centered measures: education and minitor, they explain, they could play an important role in reducing the impacts of this growing presence of arsenic. The occasional alerts we receive regarding arsenic levels in rice could make this more difficult, by turning this problem into a “Pedro and the Wolf story”: a non -existent problem that we pay attention today could become a real problem that we ignore in the future.

The lack of protein represents a risk to our health. These are the key symptoms to identify it

by

We live perhaps in him historical context of greater food abundance. It is difficult to find an era in which we have had a greater variety of food at our disposal. This is especially true for meat and fish, two of the main sources of protein. In general, today We consume more proteins than we needbut the general does not always apply and The lack of protein It can also occur in some people, for example cases of certain diets or between people suffering from certain autoimmune diseases. That is why we can ask ourselves, how can we know if we are not consuming enough proteins? Proteins are one of the three macronutrients considered basic for the proper functioning of our body, the other two fats or lipids, and carbohydrates. We associate these nutrients to meatfish, milk products, but are present in one way or another (in their constituent blocks, for example) in a multitude of foods such as legumes or soy. Proteins, although we put them in the same group are not a homogeneous group of compounds: our body has thousands of protein types. Of course, all of them are composed of a series of amino acids chained 20 of these “blocks” are enough to form this myriad of proteins in our body. Our body is able to synthesize 11 of These amino acids But for the other nine, called essential amino acidswe must obtain them from food. For this we need proteins: our digestive system breaks them down in amino acids so that our body can rebuild them according to their need. We call “Complete proteins“To foods containing all essential amino acids. A list of food with complete proteins would include meats such as beef or chicken, fish, eggs, dairy, soy or quinoa. If our body does not consume enough proteins or other amino acid sources, we can fall into the lack of any of these nine essential amino acids, so that our body can lose the ability to generate its own proteins which results in problems such as the Hypooproteinemiathe lack of protein in the blood. Symptoms Before the lack of proteins becomes a problem, we can pay attention to some symptoms that alert us to lack. Health experts from the University of California in Los Angeles They prepared a time ago a list With six indications that can help us detect the lack of protein. In the article they explain that fragility in hair and nails is sometimes the first sign of a protein deficiency. Another sign is in the feeling of weakness and hunger. Hunger usually indicates the lack of food, sometimes it can also indicate a more concrete nutritional lack. A third indication is in our immune system. The lack of protein can limit our body’s ability to defend against external threats so we can find ourselves more sickly due to this lack. The lack of protein can also manifest in changes in humor or difficulties in thinking. This is due to fluctuations in blood sugar levels and the effect of proteins in brain neurotransmitters responsible for regulating our mood. The fifth indication indicated by these experts is muscle weakness. Proteins are indispensable to build and repair muscle mass, without it we can end up losing it. The last of these symptoms is in the Appearance of fractures by stress in the bones. The integrity of these also depends on this type of compounds. Proteins are fundamental to our body and the difficulty in creating new molecules can cause us problems of very diverse type. As usual in nutrition, excess can also be linked to some problems. Some estimates calculate that excessive protein consumption may appear if we take more than two grams daily per kg of body mass. A varied and healthy diet is key to avoiding problems both by excess as defaultin regards to proteins and with regard to any other nutrient. This is especially important for those who, by their own or for health, must eliminate some usual piece of their menu. No food is essential but there are nutrients that they are.

Spain looked at Chinese cars as a salvation table. In the commercial war, the risk of dying drowning runs

by

“Spain is in favor of more balanced relations between the EU and China,” with these words Pedro Sánchez, president of the Government, has defended his approach to China before the commercial war that is being freed and during the same. And the automobile sector has a lot to do. “Essential partner”. With those words Pedro Sánchez has defined the relationship that China should have with the European Union. The words have pronounced them during their meeting with Xi Jinping, president of the country. The Spanish is in a round of visits by Asia in which he is stopping in China and Vietnam. Both countries have been severely punished by the United States. China still maintains 125% tariff Despite the 90 -day truce that Donald Trump has granted. Vietnam had been punished with some 46% tariffs. The importance of words. This “essential partner” is not accidental and shows Spain’s approach to China in full tension for the commercial war that are pounding the United States and the Asian country. In fact, the words of the words of the European Union is unmarked as “partner, competitor and systemic rival”, collected by The country. Sanchez needs to play with tact with his statements. Only a few days ago, Scott Besent, secretary of the United States Treasury, said that “I am not sure if it was the prime minister or the Minister of Economy of Spain, who made some comments this morning: ‘Maybe we should align more with China.’ That would be to cut off the neck”, in words collected by The confidential. Xi Jinping, meanwhile, thanked Sánchez for the “firm will” to maintain good relations between the two countries, emphasizing that it is the third time that the president of the Spanish Government visits the Asian country, they point out in The world. The equilibrium game. Spain has encountered the most uncomfortable view at the right time. With the agenda already scheduled, it was seen if the president of the Government would be willing to go to China in the middle of the commercial tension with the United States. The single presence is seen as a Spanish approach to the Chinese side and, of course, It is unmarked from European politics that bets to get wet as little as possible. However, Spain has a good number of Chinese investments in our country. The commercial balance between the two countries It is still very unbalanced In favor of China (we import goods worth 45,174 million euros and export there products worth 7,467 million euros) but China has the key in key sectors. Putting the carpet. Without a doubt, one of the sectors in which Spain wants to influence is the car. China is disembarking in Europe. His commercial war with the United States will force him to disembark in greater force in Europe and Spain is a perfect gateway. With the fees to the electric car, the plug -in hybrids and the Chinese low ranges vehicles have A huge opportunity in countries like Spanish where “electricity” is not so developed. All their companies need to open markets outside China to seek profitability. If the perspectives are maintained, byd will be in 2025 One of the five greatest manufacturers of the world. Given this situation, Spain is clear that it wants to be a very important part of Chinese landing in Europe. The automobile sector is essential for Spain. Not only in its factories, you have to add ports that receive cars, distributors and a Powerful auxiliary and component industry. It is better for us. The biggest problem facing Spain is that it is best to open to China if you want to open your business routes in the automobile sector. When the tariffs of Chinese electric car were voted for the first time, Spain was favorable. A visit to China and a threat of attacking the Spanish pig directly (whose exports to China are key) He changed the Executive idea. But, in addition, other threats float in the air. In Europe, France or Italy remained firm in their favorable vote to tariffs on Chinese electric cars. Then, China ordered to stop investments In those countries and since then we have not had news of new approaches. At the moment, Spain has Chinese investments in different ports To receive and start distributing cars that arrive from Asia, the investment of Chery in Barcelonathe agreement between Catl and Stellantis For a battery plant in Aragon or the Extremadura projects to produce batteries for electric cars. But there are certain problems. In a first reading, it seems clear that if Spain has the opportunity to continue expanding its Chinese investments in the automobile sector to be key in the European car of the future and if you have a threat to its head of withdrawing investments or torpedoing trade between the two countries, the approach to China seems completely logical. The problem is to pull the rope tense, irremediably, on the other. The United States has already warned Spain that its position is not correct and some sectors are (obviously) worried. The direct impact In the automobile industry it is not too high but, for example, shipments to the United States of olive oil They have shot under the threat of tariffs. What can we expect? Given this context, Spain will have to play its cards to several bands. Approach enough to Beijing but without burning. It will be necessary to see if the United States maintains its commitment to tax trade with the European Union with a flat rate or if it extends tariffs by sectors, which can be an indirect attack on a specific country. A good example is the 25% tariff to the car. The United States government has repeatedly decided to pause its tariffs to Mexico or Canada but keeping them in the car market is a clear attack on these countries. Also to Germany, in Europe, which is The country that exports more vehicles to the United States. We will have … Read more

After two catastrophic failures, we believed that Spacex would not risk with the next starship. We were wrong

by

Starship’s next flight will be one of the most tense in the history of the rocket. Not only because the last two releases will end in paths explosions and with deviated airplanes to avoid the rain of rubble. Also because it will be the first time that Spacex reuse a rocket. Zero-Touch reflight. In addition to a 123 meters high mole, Starship is the first rocket designed to be quickly reusable. Spacex’s idea is that Starship takes off, lands and throws himself again after a few hours, as if it were a commercial plane. The company has partially advanced in this Objective of “Zero-Touch Desflight” or relaunch without intervention. The first stage of the rocket, the 33 -engines Super Heavy propeller, has landed in the arms of the launch tower three times: Booster 12 in flight test 5, Booster 14 in flight test 7 and Booster 15 in flight test 8. It was planned that the second stage of the rocket, the six -engines Starship ship, would make its first landing attempt during flight 9. To do this, the earth would orbit and re -enter the atmosphere until they perch on the arms of the second launch tower; Already finished in Starbase, Texas. However, the last two starship exploded at 8 minutes of takeoff For a defect in a redesign recent. A second -hand super heavy. The expected thing was that Spacex was taken calmly to flight 9 to compensate for the last failures, but the company has just announced a surprising decision. The next launch, scheduled for mid -April (if the Federal Aviation Administration of the United States is approved), will be done reusing the booster 14 of flight 7. This propeller first took off on January 16, 2025 and, after separating from the Starship ship, returned to the launch base to become the second Super Heavy that Spacex has captured with the arms of the Mechazilla tower. Of the 33 Raptor engines that you will wear during your second launch, 29 are already used engines. Another rocket that lands and takes off. The only orbital rocket with demonstrated capacity for propulsive landing is the Falcon 9 of Spacex. Specifically, its first stage, which usually lands in an autonomous barge in the ocean after throwing satellites or spacecraft. A few weeks later, you are ready to reuse (Generally, in Starlink missions). The second rocket to get it could be Starship, also from Spacex. Not in the “Zero-Touch reflight” mode, but after a restoration process and changing some engines, but it is a first step. And in fact, it is a step that nobody else has achieved apart from Spacex. The company that is closest is Blue Origin, who tried unsuccessfully on the opening flight of the New Glenn rocket. In China, Landspace is also achieved with his Zhuque 3 rocket. There will be no second capture. The bad news is that Spacex will not try to capture the Booster 14. The rocket, which has just passed some ignition tests on land, will merit in a controlled way in the Gulf of Mexico to test a more pronounced attack angle during the re -entry, which in the future will allow you to perform other flight profiles. Anyway, all eyes will be put in the Starship 35the third ship of the “Block 2” version. Its two predecessors exploded shortly after separating from the Super Heavy propeller, both for a flight of propellents due to excessive vibrations in the engines area. Starship 33 disintegrated after a fire and Starship 34 lost control after the explosion of an engine. The investigation of flight 8 is still open, so FAA has not yet given its authorization for flight 9. Even so, we should not take long to see it, taking into account that the rocket is almost ready and the renewed political power of Elon Musk It has already allowed accelerating the procedures in the previous releases.

Science has tricks to see it without risk

by

Saturday 29 The sun will darken hidden by the moon. It is a partial eclipse that will be visible from an important fraction of the southern hemisphere: almost all of Europe (including Spain) can see this concealment, as can also be seen from part of North America, Africa, Asia and even from a small fraction of South America. Solar eclipses are astronomical phenomena that hardly go unnoticed. Time has spent since these events ceased to be a sign of evil agüero, but we also know that they have a certain associated risk: the risk of damaging our view If we do not properly protect our eyes. Looking directly at the sun is never a good idea. But during an eclipse, even less. As Francisco Doménech and José A. Álvarez explain in The countrythe sun emits its light in a wide segment of the electomagnetic spectrum, a range of frequencies that expands beyond the visible spectrum, entering the infrared and ultraviolet. UVA rays (ultraviolet-a) from which we have to protect ourselves in summer and in certain circumstances are an example of how these invisible rays can still affect ourselves if we do not realize at the time. The energy transmitted by the different spectrum frequencies is inversely proportional to its wavelength. That is, shorter wave frequencies such as ultraviolet carry more energy than the longest wave, such as infrared. Despite this, both extremes can have a negative impact on the physical integrity of our eye. What do we expose ourselves? Looking at the eclipse without proper protection can expose permanent damage in the retina and in the cornea. Damages that can even come out with the loss of sight. According to Geoffrey Bradford, Professor of Pediatrics and Ophthalmology at the University of Virginia Occidental, In an article for The conversationour eyes have a natural capacity to adapt to different luminosity conditions. However, DIRECT OBSERVATION OF THE SUN It can exceed the ability of the eyeball to protect yourself from excess light. In the cornea, says Bradford, there is a risk of solar or actinic keratosis. This disorder can make our sight cloud and cause pain. This injury would be reversible but may require several days for your cure. The problems in the retina are not painful but they can be more serious, Bradford adds. Retinopathies can affect our sightcreating a blind spot in our central vision, visual distortions and the alteration of our color perception. An additional problem is that if we look at the eclipse we will not take pain even though our eyes will be suffering. This can generate a false sense of security while we harm our view. See it safely If we want to see the eclipse directly we will need glasses specifically designed for the observation of this type of event. Sun glasses offer protection against solar rays in everyday situations, but eclipses are not such a thing, so in practice their protection of nothing serves us in these situations. Even if we wear eclipse glasses, we must make sure they are duly approved and comply with the international ISO 12312-2 standard. The National Geographic Institute (IGN) offers us on your website Additional information, including points of sale, to take into account if we want to acquire these glasses. IGN himself also warns us that we must avoid observing the sun with devices such as cameras, or instruments such as telescopes or prismatic that are not prepared for the observation of these phenomena, something that is only achieved through special filters, not as usually used in other contexts. If we do not have specialized glasses, we can still observe the eclipse indirectly. If we walk through a wooded zone during the eclipse we can see a curious phenomenon in THE SHADOW THAT PROJECT THE TREES LEAVES. If certain conditions are given, we can see how the shades of the eclipse can be seen among the shadows. Also We can cause this effect Using, for example, the holes of a strainer. We can, for example, use a Stenopic projector, which we can manufacture ourselves with a cardboard box, aluminum foil, Celoy scissors. NASA explains how In a video. A last trick that IGN offers us It requires a mirror, a wall and a paper that we must also cut a hole. It is enough to cover the mirror with a role in which we will have previously made a hole between five and ten millimeters in diameter. With it we must reflect sunlight on a flat wall in which the image of the eclipse will be projected. Saturday’s eclipse is just the appetizer of A complete menu of eclipses that awaits us in the next three years. This eclipses parade includes two total eclipses that in August 2026 and 2027 They will be visible from a good part of the Iberian Peninsula, and an eclipse annular in January 2028 also visible from our environment.
