Siberia stays in the dark good of winter. In 1988, Russia had an idea to solve it: mirrors in space

Towards the end of World War II, Some documents in Life magazine They revealed one of the many ideas that Hitler’s Nazi Germany had: a kind of solar projectile through A giant orbital mirror to destroy enemies or even whole cities. Obviously that never happened, but decades later it served as a slight inspiration for a Russian scientist who started from a fascinating idea: how could we extend the hours of the day? Convert the night. The truth is that the background idea is not new. Over the years, Humanity has sought to extend the day (Understood as day and light) with technological tools, from electric light to digital communications. However, in the 1990s, a group of Russian scientists tried to take this concept to the extreme: launch huge space mirrors to reflect sunlight towards the earth and prolong the day. Vladimir Syromyatnikov. The project we are talking about was directed by Vladimir Syromyatnikovone of the most influential space engineers in historyknown by Develop the ship’s coupling mechanism which is still used at the International Space Station. During the 80s, his interest focused on The design of solar candles that could use solar radiation To propel ships through space. However, in postsoviet Russia, obtaining financing for space projects required clear economic justification. Thus, Syromyatnikov reformulated his idea and presented it as One way to illuminate Siberia’s arctic regions during the dark winter monthsincreasing productivity in agriculture and industry. Yeah, I would try to turn on the sun for the polar regions of Russia After the night fell. Image of Znamya Znamya and his brief success. In 1988, Syromyatnikov founded the Space Regata Consortiumwith the support of Roscosmos and several state companies. His motto was very clear: “Diury light all night.” The idea not only promised to reduce electric lighting costs, but also Facilitate rescue in disasters, military operations and night construction projects. The first prototype, Znamya 2, He was sent to space in February 1993 aboard the progress M-15 ship and subsequently deployed from the MIR Space Station. Once in orbit, he began to turn to deploy its reflective surface. The mirror, 20 meters in diameter, achieved the feat of Reflect a beam of light equivalent to that of a full moon, illuminating an area of ​​5 km in diameter while crossing Europe and Russia 8 km per second, even Astronauts in Mir confirmed that they could follow the flash from space. The problem? The reflected light was more diffuse than expected and difficult to controland the weather was not taken into account. Plus: The cloudiness prevented the majority of observers on land to notice. Hours later, The mirror disintegrated by re -entering the atmosphere. ZNeamya 2.5. Despite its short duration, the experiment showed that the concept was viable, which promoted Znamya 2.5 planningwith a larger mirror and the ability to maintain the beam of light on a fixed point. Thus, in 1999 this second version was launched with A 25 meter diameter mirror. This time, when deploying, one of his fine sheets became entangled in an antenna from the Progress ship, tear the structure. The attempts to free her failed and the mirror had to be exorbitantburning in the atmosphere. The next step would be Znamya 3, with a 70 -meter mirror, capable of illuminating entire cities. What happened? That The failure of Znamya 2.5 and the lack of financing buried Syromyatnikov’s project and dream. In addition, the opposition of astronomers and environmentalists grew, arguing that Space mirrors could alter natural cyclesaffect astronomical observation and confuse wildlife. A man and his tireless search for light. Despite the failure, Syromyatnikov continued looking for financing to build a permanent mirro system. We talk about An estimated project of 340 million dollars. His vision was a world where cities would not need artificial light and the days had no nights. However, investors lost interest and the project was abandoned. Syromyatnikov continued his work on coupling systems until his death In 2006, dedicating his days to work without rest, in an ironic parallelism with his obsession with eliminate The night. The legacy. If you want, that was also the end of a space “exploration.” In any case, much less the background idea is over. Today, the idea of ​​taking advantage of sunlight from space has resurfaced In the investigation of orbital solar plantsthe same as They could send energy to Earth through microwave. However, Znamya is still a reminder of the limits of technology and the need to respect natural cycles. Russia’s attempt to convert the night and enlighten Siberia in winter was both a demonstration of human ingenuity and an experiment that, in the end, crashed with the laws of nature and resistance of the modern world.

Egypt and Jordan reject Trump’s idea of ​​moving Palestinians from Gaza to their territory

The Ministry of Foreign Affairs of Egypt rejected the US president’s proposalDonald Trump, of displacing the population of the Gaza Strip to his territory or other Arab countries and defended the creation of a Palestinian State as the legitimate right of his people. In a statement, the Ministry reaffirmed “Egypt’s adherence to the political solution to the Palestinian question”, which involves “ending the occupation and returning the usurped territory to the Palestinian people”, to guarantee their legitimate right to their land. and homeland. He also stressed its rejection “of any violation of these inalienable rights, whether through settlements or land annexationsor evacuating those lands from their owners through displacement or encouraging the removal or uprooting of Palestinians from their lands, either temporarily or permanently.” In this way, he responded to the statements that Donald Trump made yesterday, Saturday, to the journalists who were traveling with him aboard Air Force One, and to whom he said that he had spoken with the King of Jordan, Abdullah II, about the idea of ​​building housing. and transfer the million Gazans from the Gaza Strip to countries like Egypt or Jordan, according to CNN. According to the Egyptian department, displacing the Palestinian population of their land “threatens to further spread the conflict in the region” and hinders the possibilities of peace and coexistence between its peoples. In this sense, he explained that the Palestinian territory includes the unity of the Gaza Strip and the West Bank, including East Jerusalem, in accordance with the resolutions of international legitimacy and the lines of June 4, 1967. Jordan supports the creation of the Palestinian State On this same day, the Jordanian Foreign Minister, Ayman al Safadi, He expressed himself in similar terms and also rejected Trump’s approach while demanding the creation of the State of Palestine to fulfill the right of the Palestinian people and achieve the long-awaited peace in the Middle East. “Everyone knows that the solution to the Palestinian cause lies within Palestine. Jordan is for the Jordanians, Palestine is for the Palestinians,” he stated before highlighting that the path to regional security and stability is for “the Palestinian State of sovereignty to live in peace alongside Israel in accordance with the solution of the two states.” Keep reading:• Trump calls Gaza “a demolition site” and wants Jordan and Egypt to welcome its inhabitants “temporarily or long term”• Ceasefire agreement between Lebanon and Israel ends• Israel releases 200 Palestinian prisoners after 4 hostages released by Hamas are reunited with their families

Malaysia came up with the idea of ​​painting its roads fluorescent to illuminate them at night. The problem was the price

In February 2024 we saw that the continuous line of a good part of the A-355, one of the roads with more accidents of Spanish territory, dawned with a thick continuous red line. It was a pilot measure by the DGT to highlight the prohibition of overtaking on that road. A few weeks earlier, a similar program was developed in Malaysia: repainting the road markings of certain roads with a photoluminescent paint. Not even a year has passed and it seems that they will not continue painting. The reason? It is too expensive, which has raised the question of… and they hadn’t thought of that before? The pilot. In mid-November 2023, the Government of Malaysia advertisement the launch of a pilot program that aimed to highlight the lines of certain roads. Using photoluminescent paint with the ability to glow at night. The authorities commented that these initiatives were suitable for dark areas that lacked public lighting. The lines shine for 10 hours and, in case of heavy rain, they also give off a certain shine that helps make them more visible, allowing drivers to stay in their lane. The images leave no room for doubt: it looks much better than the traditional white line, also better than reflective indicators. The project attracted attention. Initially, only 245 meters of road were painted at one intersection, representing about 490 meters of road markings, but other states began to carry out their own tests. Almost 20 times more expensive. The problems came practically from the beginning. The Malaysian Ministry of Works already warned that they were going to be very attentive to the results of the pilot program and the ability to paint on other roads, since the price of the new paint could be a problem. And so much so that it has ended up being an inconvenience. From the Ministry of Works reported that conventional paint costs about 40 ringgit per square meter, about 8.65 euros. Photoluminescent paint costs 749 ringgit per square meter, more than 160 euros. It costs 19 times more per square meter. Putting on the brake. Despite the enthusiasm with which the population received the measure, Malaysia’s deputy labor minister, Ahmad Maslan, commented a few weeks ago that it was not likely that they would continue painting. “The cost is too high, so we probably won’t continue with glow-in-the-dark lanes,” stated. It is curious when, months before, 31 roads had been identified that could have received this type of paint. Maslan stated that the tests did not meet the expectations of the ministry’s experts, without giving further explanations. Questions and suspicions. This is part of the eternal debate about priorities, budget and security, since we must remember that the areas that were going to receive this type of paintings are wooded and lack lighting, making it dangerous to travel through them due to interactions between humans. as by the action of animals crossing each other. And, evidently, the news has raised suspicions of corruption in local mediawith users who wondered if they didn’t know all this before starting the pilot project, what are those expectations that the painting has failed to meet… and that someone will have filled their pockets with the initial contract.

Johann Hari, journalist: “The idea that obesity is a sin is deeply rooted in our culture” | Health and well-being

A couple of days after starting to take Ozempicsays the journalist and writer Johann Hari (Glasgow, 46 years old), he woke up with a strange sensation, unknown to him: he was not hungry. He got out of bed and went out to have breakfast at the bar, the usual breakfast, a chicken sandwich with mayonnaise. He took a couple of bites and couldn’t finish it. It was full. The medicine, belonging to that generation of drugs that have revolutionized The fight against obesity by imitating the effect of a hormone (GLP-1) that tells us when we are full, was restoring a lost perception: that of satiety. Hari tells this and other anecdotes about his experience with these medications in his new book Lose weight at any price. How Ozempic and other drugs are going to revolutionize our diet and our physical and mental health (Península), which reaches bookstores today. In these pages, the journalist, who has been overweight since he was young, embarks on a journey, accompanied by obesity experts and scientists who have participated in the development of the new drugs, for the benefits and risks of these treatments, the uncertainties that surround them and the uncertain scenarios that open in the field of health and beyond it. The journalist attends EL PAÍS by videoconference from London. More information Ask. He has spoken to many scientists. What has impressed you the most about what they have told you? Answer. Which obesity it really does you. Since I was seven years old I knew that being overweight is not good for your health, but I was surprised by the evidence of how serious it is. If you are obese, you are much more likely to suffer a heart attack, stroke, dementia and cancer. If you are obese by the time you are 18, you are 70% more likely to develop type 2 diabetes. And diabetes is the leading preventable cause of blindness in the UK and limb amputation in the US. Q. He assures that these anti-obesity drugs are destined to be the defining medicine of our time, like birth control pills or Prozac at other times in the last century, for example. Why do you say it? R. Because obesity is the biggest cause of death in the Western world. And now we have a medicine that, if you take it, reverses it and puts an end to it. It’s amazing. So all of us who are overweight or obese have a choice, but we have to compare the risks of remaining obese with the risks of these medications and think about it a lot. (These drugs) They are going to have enormous effects. Q. How can they change our lives and our culture? R. The change is enormous. Jefferies Financial, which is a financial consulting firm, made a report for American airlines saying that they may have to spend much less money on jet fuel, because it costs more money to fly with heavier people and that is going to be a much smaller population. Also in Los Angeles there has been an increase in demand for jewelers to change and adjust wedding rings because people have lost so much weight that the rings no longer fit on their fingers. Approximately 20% of Americans have already tried these medications. This is huge. This is an astonishing scientific advance that will profoundly change society for better and worse. “The foods we eat are undermining our ability to feel full” Q. Regarding this negative part, he exposes some issues that the consumption of these medications entails, such as the risk of losing the culture of body positive or what would happen if people with eating disorders access these drugs that help them lose weight. Have you found answers to these questions? R. The invention of these drugs is like the discovery of fire. Fire is a great tool if I use it to heat my house, but it is terrible if I use it to burn my house down. And in the same way, when something as powerful as this is discovered, it will have great positive effects and great negative effects. If you are overweight or obese and start taking these medications, for example, you are 20% less likely to have a heart attack or stroke in the next 18 months. But you also mentioned something that worries me a lot: when you take these medications, you eat much less; and that’s good if you’re obese like me, but people with an eating disorderanorexia for example, if you are thin and start taking these medications, you can kill yourself with them. Therefore, one of the things we must do is regulate these medications very strictly. Q. The book also delves into what makes ultra-processed foods so addictive. Do they cause a kind of short circuit in our brain systems? R. If you look at a photograph of a beach in Spain in 1979, the year I was born, everyone is very thin and you wonder: where are the obese people? So, obesity was very low. Modern humans have been around for 300,000 years, but obesity was extremely rare. And basically, during my lifetime, it exploded. What happened? We know the answer: Obesity skyrockets everywhere people make a change, when they go from eating mostly fresh foods they prepared that day to eating primarily processed and ultra-processed foodsThat is, food is made up of chemicals in factories in a process that is not even called cooking, it is called making food. This new type of food affects us in very different ways. The foods we eat are undermining our ability to feel full and what these new medications do is restore the feeling of satiety. Q. And what about the industry’s responsibility in this context? R. Need regulate the food industry to prevent children from being exposed to these foods that make them sick and undermine their ability to feel full. I’m talking about a long-term solution and we … Read more

Google invests another $1 billion in Anthropic, according to FT. Having a plan B was never a bad idea

In 2021, several former OpenAI employees decided to set it up on their own. Among them were siblings Daniela and Dario Amodei, who led the founding of Anthropic. Since then, their work at Claude in particular and in artificial intelligence has made them leaders in the sector. So much so that even Google, which has its own AI project, opted for them. And now they have done it again. First investments. In April 2023, with the relatively recent release of ChatGPT, invested 400 million dollars in Anthropic. That number would end up going up up to 2 billion in total at the end of that year, which consolidated the promising commitment to this AI startup. Another 1 billion. As indicated Financial TimesGoogle has invested another $1 billion in Anthropic. The data comes from people related to the movement, and the operation—if confirmed—would allow Google to reinforce its participation in the company. Rival and plan B. Claude is a fantastic AI chatbot that has been gaining popularity in recent months and is now one of the benchmarks, but it rivals Gemini, Google’s model and chatbot. It is a unique situation in which Google has Anthropic as a rival but also as a potential ally if needed. Diversifying is always a good idea. As pointed out in the FT, this operation allows Google to diversify its interests and not put all its eggs in the same basket. And Anthropic expects more financial support. According to this newspaper, Anthropic is about to close a separate investment round of another $2 billion. Lightspeed Venture Partners would participate in it. This round is expected to triple Anthropic’s valuation and place it at around $60 billion. Amazon, even more relevant. Google’s investment is already very relevant, but Amazon is the main protagonist here. The company led by Andy Jassy has invested $8 billion in the startup, and Claude models are expected to end up being an integral part of the future version of Alexa that keeps delaying again and again. They already have gas for one season. These investments will allow Anthropic to continue advancing the development of its AI models. The “Computer Use” function presented at the end of October 2024 showed a future potential full of AI agents to do things for us on the computer, and the firm certainly seems to be heading in the right direction in this area.
