China has discovered a new mineral on the Moon. It’s so fluorescent it could change the way we make LED light bulbs

by

So far, 11 unique minerals have been discovered on the Moon. The last of them has just been revealed by a team of Chinese scientists after analyzing a lunar meteorite. It is an interesting finding, because it gives us useful information about the geology of our satellite. But also because it could have very interesting applications here on Earth. From the Moon to your light bulbs. The material just described It is cerium-magnesium changesite. It is characterized by its glassy, ​​transparent and brittle appearance. The thickness of its granules ranges from 3 to 25 micrometers, less than that of a human hair. Still, it is extremely useful due to its pronounced fluorescence, which could be very useful in improving terrestrial LED technology. A necessary color change. Unlike traditional incandescent bulbs, LED bulbs do not use heat to produce light. They make the most of electricity thanks to a semiconductor material, which allows the flow of electrons from a layer with an excess charge to another with a lack of it. That second layer has what are known as voids. That is, atoms that have lost electrons, leaving something like a free hole. The moment an electron encounters one of these holes, falls inside, in a process in which energy is released in the form of light. The light obtained in this process is blue, but we have all seen that, in general, the light from LEDs is white. The color change is achieved thanks to the coating the bluish chip in which the process occurs with a fluorescent material. This absorbs some of the blue light and, in turn, emits yellow light. Both are what are known as complementary colors of light. Therefore, when you mix them you obtain white light. The more fluorescence, the better. The fluorescence of this lunar mineral is so powerful that it would be a wonderful complement to LED bulbs. White light would be obtained in a much more efficient way, resulting in even greater energy savings. More achievements for China. The Asian country has become an expert in lunar geology, thanks to the Chang’e missions. In fact, the Changesite-(Y) phosphate was already discovered on Chang’e-5, directly related to this other mineral that a meteorite brought to Earth. For now, we can only dream. Logically, going to the Moon to excavate minerals is not very viable. And if it were, it would be good to think twice before jumping in headfirst. We also don’t know if there would be enough on the Moon. It would be necessary to explore it further to know. Therefore, the applications of lunar minerals in terrestrial technology are nothing more than hypotheses. It is interesting, but it does not have a close application in time. What these minerals do teach us. Analysis of lunar geology It can teach us many things. If we find mostly minerals that also exist here on Earth, we can understand that, at some point, similar conditions existed on Earth and the Moon. On the other hand, if many unknown minerals are found on Earth, as is already happening, it is understood that there were conditions on our satellite that have not occurred on our planet. All this serves to understand very well where we are and where we come from. Let’s stay with that instead of thinking about mining our satellite and leaving it without resources as we are already beginning to do on Earth.

The war has led many expats to look beyond Dubai. In Italy there is already a city willing to take advantage of it

by

He skyline It may be Dubai’s most recognizable feature, however in recent decades the city has gained something much more important (and complicated) than its skyscrapers: prestige. For years the expats half the world has seen in the United Arab Emirates (UAE) a destination in which to settleattracted by their tax advantagesadministrative facilities, luxury and stability of the country. Now the shock wave of the Iran war is erasing some of that image and has led some expats to look for alternatives in safer cities. An Italian city already appears on the horizon. The other bill of war. As with all wars, that of Iran It looks a lot like a set of dominoes. Operation ‘Epic Fury’ launched on February 28 by Washington and Tel Aviv on Iran ended the life of Ayatollah Ali Khamenei, supreme leader of the Islamic regime; but that was only the first step of the war. The first in a long chain of pieces. Since then the conflict has escalatedaffecting international markets, skyrocketing the price of crude oil and infecting the rest of the Persian Gulf. We had the most graphic proof in the first days of the war, when Iran harshly punished some US allies in the region, including the UAE. Their attacks blocked Gulf airspace, unleashed the biggest crisis of aviation since the pandemic and left images that until recently were unimaginable, such as luxury residences attacked by Iranian drones. Reputation blow. The casualty toll in the UAE is relatively low (the Emirati authorities numbered at 13 those killed during the attacks launched by Iran), but the reputational damage has yet to be measured. For decades, the Emirates knew how to carve out a niche for itself as a favorite destination for expats from other countries. As explained a few months ago Guillaume Giroux, of the Dubai Inmo firm, in cities like Dubai, fortunes found tax facilities, bureaucratic agility, stability, an attractive real estate market and a high standard of living, especially for people accustomed to luxuries. Some of that magnetism remains, but the Iran war has tarnished the image of a safe, reliable and ‘boring’ (in a good way) destination created by the UAE. Has it changed that much? Public discourse certainly has. If it is news for hosting more than 81,000 millionaires or attract thousands of residents wealthy in just one yearDubai has made headlines for the chaos unleashed by the Iranian war. At the beginning of March Financial Times spoke of people driving 10 hours to cross the border into Oman, desperate to leave the region. In Guardian even they assured that a jet company was asking 85,000 euros (triple the normal amount) for a flight to Istanbul. They are specific cases, but they punish the UAE’s global projection. Looking for alternatives. It is unlikely that Dubai will suddenly lose the image that has been built up for years and it remains an unknown what the effect of the war will be in the medium and long term. there are those already warn that he is not considering leaving the Emirates. None of the above means that there are already millionaires looking for alternatives. I confirmed it recently Guardian in a chronicle explaining that as Dubai sees its reputation as a safe haven erode, there is expats thinking about the best way to return to Europe. The article, signed by Lauren Almeida, focuses on British billionaires, but still leaves out an interesting idea: when looking for European destinations, there is one in particular that seems to be winning. Which? Milan. “Those leaving the UAE can easily imagine themselves living in Rome or Milan, metropolitan and international centres,” point Armand Arton, who is dedicated to advising millionaires on citizenship and investment plans. Why’s that? For a sum of factors. In a way, Milan offers the rich a package similar to the one they find in Dubai: a attractive tax regimea rising real estate market (something especially interesting for those who buy with an investment mentality) and above all luxury. It’s nothing new. In September the Italian edition of Idealista explained that Milan was becoming one of the most attractive destinations in Europe to attract great fortunes. “Italy offers the best advantages: single tax and good quality of life,” insist Arton. “It’s a beautiful country. Milan has a very developed financial services sector, many of the things that are attractive in London, Milan also has them,” adds Marc Acheson of Utmost Wealth Solutions. This sum of factors, added to its environment, schools, services and cosmopolitan lifestyle, explains that the Italian city be home now from some of Europe’s biggest investors and bankers. Also the increase in price of your home. Luxury and something more. The attractiveness of Italy as a city is not the only factor that explains its ability to attract expats. Another is its tax policy. In 2017 the country introduced the “single rate”also known as “Ronaldo tax” and that it is designed precisely to attract wealthy foreigners. In summary, the regime allows new residents (foreigners and returned Italians) to pay 300,000 euros annually for income obtained outside the country. It may seem like a high tax, but as its name indicates, it is applied in a fixed manner, regardless of the base amount, which makes it an interesting option for large fortunes. Until recently, its amount was also lower, making it even more attractive. When it was introduced, the “single rate” amounted to 100,000 euros annual. In 2024 that figure rose to 200,000 and did not reach its current level, of 300,000 euros, until this year. This tax advantage can be enjoyed for only 15 years, but it has extras. Marking distances. It’s not just about what Italy has done. As explains the Golden Visas platform, the Italian system gained attractiveness after in 2024 United Kingdom review its tax regime for non-domiciled residents and for Portugal to also rethink its system. Reuters precise that in 2023 around 1,500 people took advantage of the single rate regime in Italy, … Read more

The blockade of ingredients to Nazi Germany led Coca Cola to throw away whey and apple pulp

by

When you open a Fanta, you hardly think about World War II. However, this fruit-flavored drink was born in 1940 within Nazi Germany. It was a solution from Coca-Cola, owner of the brand, to the blockade of ingredients that the allies imposed on the country. Quite a commercial turn that would result in one of the company’s most popular drinks. To block. In September 1939, when Germany invaded Poland and the United Kingdom and France declared war on the Third Reich, the economic consequences spread far beyond the battle fronts. American multinationals that maintained industrial ties with German territory saw communication with their subsidiaries interrupted. The British naval blockade closed the ports; Trade with the United States, which had grown throughout the previous decade, stopped. The Coca-Cola situation. The company had been operating in Germany since 1929. Max Keith was a German manager who had assumed control of the subsidiary and built a giant infrastructure from scratch with bottling plants and distribution networks. He had even managed to produce on his own seven of the nine secret ingredients. But the concentrated syrup traveled to Germany from Atlanta, headquarters of Coca-Cola. When the embargo cut off that supply, the plants ground to a halt. The alternative was closure, but Keith did not give in. The remains. What he did was look for substitutes in what he had at hand, waste from other food industries. How did I count? expert Mark Pendergrast“what was left of what was left”: whey, a byproduct of cheese making; leftover apple pulp from cider presses; fruit peels; beet sugar, because cane sugar was a luxury… the resulting liquid was a brownish yellow, much less sweet than any modern soft drink, and its flavor changed from batch to batch depending on what ingredients were available. A name. Keith gathered his team to name the drink. He asked them to use their imagination, Fantasy. And from there the name came directly, with the advantage that it worked in almost any language without the need for translation or phonetic adaptation. It was an immediate success: in 1943 Coca-Cola sold approximately three million cases of Fanta in Germany. AND although the soft drink never had a direct connection with the NazisKeith did manage to integrate his advertising into the regime’s events, including the 1936 Berlin Olympics. In fact, he could have registered Fanta in his own name, but he did not do so. A success. Fanta was not drunk solely as a soft drink. Sugar rationing was so severe in wartime Germany that in many German homes it was used for sweeten soups and stews. Keith had obtained a partial exemption from sugar rationing in 1941, making it not only a soft drink, but also an accessible sweetener. It was not an isolated case. Fanta was not a rarity. The World War II food industry reformulated several products forced by embargoes and rationing. Nescafé, launched in 1938arose from the need to dispose of surplus Brazilian coffee at a time of commercial crisis: its soluble format allowed it to be distributed under difficult logistical conditions, and it became a standard supply for the American army. Margarine was a substitute for butter in times of Napoleonic shortages, and experienced a second massive expansion in Europe in the 1940s because butter was rationed. Post-war. When Coca-Cola relaunched Fanta in Naples in April 1955 with an orange formula made from local citrus, the name was the only thing connecting it to post-war Germany. The Italian company SNIBEG had developed the recipe on its own and Coca-Cola bought itgiving it the name of the one who already had the intellectual property. From there it grew: it arrived in the United States in 1958 and expanded globally throughout the 1960s and 1970s. Conflictive spot. However, the drink’s German past loomed large over the brand in 2015, when Coca-Cola launched a special edition in Germany for Fanta’s 75th anniversary. It was a reissue of the original recipe, with 30% whey and apple extract, distributed in glass bottles that evoked the design of the 1940s. He video campaign was especially inappropriatesince he only talked about ingenuity in times of scarcity and ignored the reason for that ingenuity: war embargoes against Nazi Germany. He concluded by inviting viewers to recover “the feeling of the good old days.” The video was removed after frontal rejection by the public and press. It was inevitable then to remember brands like Volkswagenwhose name directly alludes to the Nazi regime’s automotive program and whose plants used forced labor during the war; or like Hugo Bosswhich made military uniforms for the SS and Wehrmacht; or as the German subsidiary of IBM, Dehomagwhich provided the regime with punch card technology that allowed entire populations to be censused, classified, and tracked with a speed that manual methods made impossible. Origins that are sometimes murky due to the context, but that leave a few questions in the air about the inhumane role of any industry. Which includes the sparks of life. Header | Wikipedia

Hisense has found the key to improving the color on its 2026 Mini LED and Micro LED televisions: adding more subpixels

by

One of the challenges for television manufacturers is to evolve their technologies to improve their ability to represent color, without implying an excessive increase in production costs. Hisense seems to have found the key for its 2026 televisions to improve their image quality: add one more color subpixel to its matrix of Mini LED and Micro LED panels. The brand presented at CES 2026, which is being held in Las Vegas, two advances that seek to make colors more natural and precise: Mini LED evowhich adds a fourth cyan subpixel, and the evolution of its MicroLED panels with the RGBY Micro LEDwhich incorporates a yellow subpixel to its RGB matrix. Both changes allow televisions to better reproduce the most difficult-to-achieve color nuances. RGB MiniLED evo: cyan is the new white The televisions Current Hisense MiniLEDs They are based on thousands of small LED light diodes that illuminate the screen from behind, achieving better lighting control. This improves the contrast without sacrificing the brightness of the screen, being able to turn off more areas of the screen to achieve deeper blacks. In 2025, Hisense put on the table an evolution of that technology with RGB MiniLED, in which the white or blue mini LEDs were replaced by three RGB diodes (red, green and blue) to directly generate colorsinstead of using color filters as traditional LCD screens did. The MiniLED evo that Hisense has just presented goes one step further in this development and adds a fourth cyan subpixel to that RGB matrix. This intermediate color between blue and green helps reproduce complex tones that were previously only approximated by combining the three subpixels. Hisense’s solution is an adaptation to LED of what LG had been doing in its WRGB OLED panelsin which a white subpixel was added to improve brightness, although in this version the aim is to increase the color volume. Clear skies, water or certain skin tones look more natural and with softer gradients. In addition, local light management (local dimming) becomes more precise, reducing halos and poorly lit areas in scenes with high contrast. The introduction of this fourth subpixel increases the effective color gamut, achieving 110% coverage of the BT.2020 color space used as the professional cinema standard. Since, in essence it is an evolution (not a revolution) of the MiniLED RGB system that it already implemented last year in its top model, this new technology will be deployed to models ranging from 55 to 100 inches in a new UR9 and UR8 family, while the new MiniLED RGB evo panels will be limited to the 116UXS (which, as its name indicates, has a diagonal of 116 inches) as an evolution to the MiniLED RGB model of 2025. MicroLED RGB: three colors are no longer enough Along the same lines, Hisense has also presented improvements to the Micro LED RGB panels that it already presented in 2025 for its most premium range. As was the case with the Mini LEDs, the brand is committed to separating the color from the point of emission, replacing the blue or white diodes with three diodes that directly emit the RGB matrix. This is something that Samsung also has launched in its plans for 2026. However, in the variant presented by Hisense for 2026, a fourth yellow subpixel has been added along with red, green and blue, leaving an RGBY configuration. The yellow subpixel fills a critical gap in the spectrum that the three traditional colors cannot accurately cover. This addition improves the reproduction of warm tones and complex light transitions, such as those presented by skin, golden lights or sunsets, with softer and more natural gradients. For the moment, the new RGBY Micro LED is reserved for the 163MX RGBY model of no less than 163 incheswhich integrates millions of subpixels managed by a new processor and algorithms that balance brightness and color. The combination of greater precision in the backlighting provided by much smaller diodes and the incorporation of the yellow subpixel allows 100% of the BT.2020 color space to be achieved, bringing the quality of giant screens closer to those used in professional production. It’s a new era for LED The evolution that Hisense has presented is nothing more than confirmation that, although OLED represents an “affordable” way to obtain the best image quality, LED still has a lot to say in terms of quality and color volume. In the MiniLED evo, the addition of the fourth cyan subpixel allows intermediate colors between blue and green to look more natural, while in the RGBY microLED, the yellow subpixel improves the fidelity of warm and complex tones. In practice, these improvements translate into more consistent, natural and detailed images, without depending only on brightness or resolution. Hisense’s proposal for 2026 is presented more as an evolution in qualitative terms than as a revolution. It is a sign that the future of Mini LEDs and Micro LED involves optimizing the way colors are generated, using additional subpixels and controlling light emission with better processors and more refined algorithms.

The great Christmas revolution in Spain is not the millions of LED lights: it is the rise of "Good afternoon" and "New Year’s Eve"

by

Don’t look for them in the RAE dictionary because academics have not yet found a place for them there, but over the last few years two words have been making their way into the national Christmas lexicon: “good afternoon and new year’s afternoon”. Just like Christmas Eve and New Year’s Eve, the canonical celebrations they have begun to complement. Actually both terms are self-explanatory: good afternoon and old afternoon They are nothing other than lateness (a phenomenon upward) transferred to the festivities of December 24 and 31. It’s that simple, that effective. The formula has caught on to such an extent in recent years that it has gone from being a diffuse and spontaneous phenomenon to a settled reality that moves thousands of peopleis organized with weeks in advancehas the institutional endorsement of the town councils and gives an extra boost to the coffers of the hoteliers. New times, new traditions. Christmas is (almost by definition) synonymous with tradition, but that doesn’t mean it’s immutable. On the contrary. Over the last few years, the holidays have been enriched with new habits that, through repetition, have already become established in Spanish ‘Christmas lore’: lighting parties of the lights, the fights between city councils to erect XXL luminous trees, the ‘pre-grapes’ and of course the good afternoon and old afternoon. New celebrations that take over from others that falter. ¿Good afternoon and old afternoon? Exact. Two expanding trends that are practically self-explanatory. The good afternoon and old afternoon They are nothing other than the adaptation of the late to the two big Christmas events: Christmas Eve and New Year’s Eve. The party no longer starts at night, with a copious dinner. It begins at noon and in the afternoon, with celebrations that usually leave homes and move to public spaces such as restaurants, bars, streets and squares. It is not about replacing the family dinner on the 24th or the one that precedes the 12 bells on the 31st, but rather about rethinking the celebration with friends and family, adjusting their schedules to bring them forward towards the afternoon (even at noon) in a ‘challenge’ to the traditional dinners that go on forever and the old party favors. A proven success. It may seem simple, but it works. If you open Google and type “New Year’s Eve” You will basically find two things: announcements from town councils that inform about their celebrations (the list is extensive: Petrer, Cartagena, Torremolinos, Boadilla del Monte, Two Sisters, Fuenlabrada…) and articles of regional newspapers that they count how the “previews” of December 24 and especially December 31 have gained popularity over the years. “It’s like reliving a day of the Pilar Festival in the middle of Christmas. A terrifying vermouth, but with wonderful billing,” explained last year to the newspaper ‘Heraldo’ a hotelier from Zaragoza who told how the good afternoon and old afternoon They have carved out a niche for themselves in December. There is nothing written about how to celebrate them, but the most common thing is that the afternoons start in the hours before dinner, even around noon (about one or even a little before), and continue for hours, until eight. In Xataka Nougat has always been the most popular and democratic sweet at Christmas. Now it’s becoming a luxury Searching for the causes. that the old afternoon is gaining strength precisely now and not eight, ten or eleven years ago is no coincidence. Although it is not easy to determine the reasons that explain why a trend succeeds, the truth is that the boom in Christmas “previews” is preceded by factors that have paved the way for it. The first (obvious) is the expansion of late in Spain. Whether causality or not, as the population pyramid of the country is thinning at the base and widening in the age group between 30 and 50, evening leisure has been gaining weight. That is, venues willing to offer experiences similar to those at night parties, only at an afternoon time that prevents the client from staying up late or waking up the next morning exhausted and hungover. The legacy of COVID. Another factor that helps understand the success of the good afternoon either old afternoon It’s the pandemic. COVID not only forced us to spend weeks confined at home, it also (and perhaps because of that) rediscovered the pleasure of going out and enjoying the streets and terraces, which is precisely where they are celebrated the afternoons of December 24 and 31. This is how hoteliers explained it to them in 2024. The Digital Confidential in an article in which it was stated that attendance at the Christmas Eve and New Year’s Eve previews shot up by 25% in just two years. {“videoId”:”x80zm7f”,”autoplay”:false,”title”:”How your TOWN or CITY has changed in 40 years: this is the NEW GOOGLE EARTH feature”, “tag”:””, “duration”:”135″} Is there more? Yes. To all of the above, other equally important keys can be added, such as families being less willing to spend hours between stoves or the increase in ordered dishes to restaurants. If we enjoy more leisure on the afternoons of the 24th and 31st, it is simply because we organize ourselves differently on those days and we are less tied to the kitchens. Another key is the advantages to organize midday and afternoon plans instead of long dinners, especially if there are children involved. How icing is it the bet what have they done not a few town councils by the evening parties, especially in small towns where the afternoon has become an opportunity to celebrate (in community and with music) Christmas Eve or New Year’s Eve.

A study analyzed the power of LED car headlights. The conclusion is what all drivers already know

by

I hate traveling at night, almost as much as drive in rain. It had been a while since I went to a national one, but a few days ago I had to do it and what had to happen happened: I was dazzled on more than one occasion. Car headlights have evolved tremendously in a short time and LEDs have prevailed in new vehicles. The problem is that every time there are more signs that we have gone too far with its evolution. And a new report puts a percentage on how dangerous they can be if they are not properly calibrated… or if the car that uses them is an SUV. In short. Whether because you have a new car or because you update the headlights of a car with a few years behind it, they are one of the elements that are most appreciated on the journeys. They see you better, you see better and it is one of the most important points in terms of safety behind the wheel. If the height is correct and they are well calibrated, they are a pleasure, but it can also happen that this is not the case and they dazzle or dazzle you. There, security goes to hell for a few seconds. The British Department for Transport has published the results of a study about glare caused by LED lights. Your conclusion? They represent a road safety problem, altering the habits of drivers in the United Kingdom. We could extrapolate it perfectly. Basically, between October 2024 and early 2025, they combined objective measurements in real conditions with surveys of 1,850 drivers. The results They are devastating: 97% of them affirm that they are frequently distracted, and 96% that glare from headlights is a road safety problem. Analysis. On the one hand, we have those statements from drivers, who were asked about the frequency with which they felt distracted due to glare from the headlights of vehicles traveling in the opposite direction. On the other hand, the objective analysis. To do this, the DfT used luminance cameras and mixed the data using a machine learning algorithm to identify the variables that come into play at high glare levels. They discovered that there was a strong correlation between higher luminance levels and reports of glare in some test vehicles (logical, on the other hand). Also that road factors influence, such as circular upwards or curves to the righttimes when drivers’ eyes are most exposed to the beam of light from the headlights. In the end, these are things that a study does not have to confirm if you have ever driven at night, but what is interesting about the study is the consequences and the “culprits.” Impact. For example, more than half of the respondents have affirmed that this discomfort due to glare has generated anxiety when driving at certain hours, which is why they have reduced night driving or have abandoned it altogether. And more than 20% point out that they would like to take the car less at night because of this, but they have no other option. According to statistics and beyond the indirect impact, they estimate that glare has bound about 290 accidents annually. and the effects They depend on age: a 50-year-old person takes nine seconds to recover from glare, while a 16-year-old takes just one second, which applies another risk factor on the road to older drivers. SUV. Beyond this, they have also found that larger vehicles, such as SUVs, are the most associated with glare in surveys. This is logical: they are taller, their headlights are more aligned with the eyes of drivers traveling in the opposite direction (especially in lower cars) and it seems that all new cars are SUVsso they are the ones with the most up-to-date lights. The problem of retrofit. This term in English refers to the modification of an existing component. In short: updating with new parts and superior technologies, such as changing the brakes for better ones, installing a new infotainment system or change the original halogen headlights for LED ones. You can buy new ‘bulbs’ even on Amazon and many are approved, but there are two problems: those that are not well regulated and those that are installed illegally. The British Administration has identified that illegal conversion is a problem, since changing halogen bulbs for LED means that those housings designed for halogen do not work the same with the new LED headlights, causing dangerous glare. British ITV has intensified its analysis of the sale of these kits, with heavy fines for violators. Not simple solutions. They estimate that around 800,000 vehicles fail their annual inspection due to headlight alignment problems, but although these are UK numbers, this is a global problem (in Spain22% of serious failures have to do with the lights) which implies that, perhaps, we have gone too far with the power of our cars’ headlights. The solution is not clear. The report recommends periodic glare checks and rethinking luminance measurements in modern headlights, but this will have to be studied. In the end, it is something that we all suffer at one time or another although, as they point Our colleagues at MotorPasión, for motorcyclists there is another added problem: reflections on the visor itself.

The most unexpected treatment against cancer is LED light, and it is giving good results

by

Currently there are many research groups that have a very clear objective: find a cancer treatment that is effective, specific and above all safe. Something that can be really complex because of everything that cancer hides behind it, but science continues to give us good news. The last one comes from the University of Texas and the University of Porto which have developed a technique based on tin oxide nanoflakes (SnOx) and LEDs that allows cancer cells to be destroyed with precision. The current problem. The therapy par excellence today in the fight against cancer, without a doubt It’s chemotherapy and radiotherapy. The first of these has numerous problems that have been tried to be corrected, such as low specificity, that is, it attacks both cancer cells like the healthy ones. And this ultimately produces many side effects that can cause you to not continue with the treatment. This makes the goal of science to seek specificity and for the treatment to attack only cancer cells. This is something that is being tried to achieve with immunotherapy and techniques like CAR-T which ultimately is part of personalized medicine for each patient and which offers a very specific selection of the type of cell to destroy. But science has not stopped here. The discovery. One of the techniques that appears to be promising is photothermal therapy (PTT). The concept in this case is quite simple to understand: inject nanomaterials into a tumor and then heat them using light. This logically causes a localized increase in temperature, which selectively destroys the cancer cells that have been marked before. The problem until now was materials and light. Many photothermal therapies require high-powered lasers, which are expensive and can damage surrounding tissue. Now, a team of researchers from the University of Texas at Austin and the University of Porto have found the key to changing the rules of the game. A secret ingredient. The team has developed a new photothermal agent called nanoflakes that are made of tin oxide. After all, they are tiny sheets with a thickness of less than 20 nanometers and what is really ingenious is how they were manufactured. The really ingenious thing is how they made them. They started from a cheap and abundant material such as tin disulfide, which ironically is useless for photothermal therapy. In this way, through a ‘green’ and scalable process called electrochemical exfoliation with oxidation, which only uses aqueous media, they managed to transform the inactive tin disulfide into tin oxide that was already ready to fight cancer. And the light came. Once this material was available, all that was left was to expose it to the LED irradiation low-cost that emit infrared light at 810 nm. In this case we are talking about radiation that is very safe and does not damage healthy skin as can occur with radiotherapy, and it is also extremely cheap and accessible to everyone (even developing countries). Results. To test the effectiveness, researchers have tested cells in culture. The first thing they saw was that this treatment had no effect on healthy cells, that is, it did not destroy them. But the best comes when applying it to cancer cells results in a great reduction in the different colonies. Specifically, in skin cancer there was a 92% reduction in the viability of tumor cells, while in colorectal cancer this percentage dropped to 50%, but still maintained good results. And all thanks to an increase in temperature from 37 °C to 50 °C in 30 minutes that killed cancer cells. The future. This study not only presents a more efficient material, but validates its use with safer and more economical light sources. The researchers themselves point to the potential of LED systems for applications such as skin cancer treatment, which could theoretically be self-administered at home. This would be a great advantage for patients and would reduce the burden on health systems, although there is still a lot of research ahead to see if this therapy can be viable in a range that will surely not be less than 10 years.

Correos is desperate to find the business that will save it from the red numbers. And that has led her to selling insurance

by

There was a time (not so long ago) when Correos was basically an intermediary, a company you went to to send letters, postcards or packages. That’s how it grew. And thus he strengthened his brand for decades. The changes in demand and fierce competition in the logistics sector have, however, forced the public company to reinvent yourselfan endeavor in which he has been engaged for years without this having allowed him to abandon the red numbers that weigh down their accounts. What has altered is its relationship with users. The last (and most revealing) example is left the decision of Correos to market insurance taking advantage of its vast network of offices and postmen, which has already earned it the union reproach. What has happened? That Correos has led a curious movement in its efforts to diversify income and leave behind the red numbers. a few months ago reached an agreement with the company AXA to market its private insurance. The alliance was announced in spring, when it was applied in 32 offices with a view to expanding to more than 800 branches throughout the country over the months. At that time, the Post Office detailed which would initially be dedicated to distributing policies for vehicles, homes, health and life and death insurance, although without closing the doors to expanding that offering to “any product” from AXA. Why is it news now? The agreement It closed in February and Correos began to market AXA insurance in mayupon registration as exclusive agent. The initiative has now made headlines again for a reason that has more to do with form than substance, although it gives an idea of ​​the extent to which the public company is committed to diversifying its services. CCOO has denounced that the company is entrusting postmen in rural areas with the task of selling policies, “a function completely unrelated to their traditional delivery work.” “Instead of strengthening the public service and hiring more staff, the management is dedicated to improvising and diverting work towards commercial tasks that have nothing to do with Correos’ mission,” ditch CCOO, which warns from its office in Castilla y León: “The viability of the company cannot be reduced to the sale of insurance by rural postmen. Correos cannot become a network of street vendors. Its function is to communicate, connect territories and guarantee rights, not do business with private insurance.” Why is it important? Because of the context, which is as or even more important than the measure itself. Insurance is not the public company’s first bet to strengthen its accounts in a challenging context, marked by the collapse in postal demand and an increasingly disputed parcel sector, in which it has to compete with multinationals and is losing market share. It’s nothing new. Years ago the company already launched one of its bets more ambitious: Post Marketa space of its own e-commerce who aspired to become ‘Amazon Post Office’. The objective: to take advantage of the boom in online commerce with a differentiated commitment to mark distances from giants such as Amazon or eBay, a “market for local products in which national producers and artisans (…) come together with online buyers.” In the presentation of the platform, in 2020, in fact focused on those two concepts, “local” and “artisan”. Today in Post Market It can be found from food and drinks to beauty, home, toys, fashion and pharmacy items. Have there been more initiatives? Yes. A few. In an attempt to find its place again, the company has opted for prepaid cardsthe telephony and fiber or the marketing of O2 servicesfrom Telefónica. In recent years he has also experimented with such ambitious projects as Correos Cargoan air parcel transport service in the Latin America-Europe-Asia axis, and even studied launching to commercial rail transport with the help of Renfe. Why this effort? Because Corres is very big. A lot. And the scenario in which he has to deal has changed. A lot too. With more than 50,000 employees and 2,000 offices it is usually said which is the largest public company in Spain. And how recently recognized to elDiario its strategy director, José Miguel Moreno, the company has been faced with the delicate situation of reinventing itself or disappearing. “Society is transforming and postal operators either do it or die.” It’s not just theory. According to the data revealed a few months ago by ABCLast year, Correos recorded losses worth 95 million euros, a hole that widens the carryover in previous years and that even has taken its toll to the accounts of the State Industrial Participation Company, to which it is linked. And how to turn it around? The million dollar question. That is what Correos has sought in part with its Strategic Plan 2024-2028, validated a little over a year ago by SEPI and that aspires to “transform, recover and reposition” the company to “change its business model.” With this purpose, it aims to reinforce its weight in the postal sector, give a boost to parcel delivery and “increase and diversify income” through “new activities, such as financial services, administrative procedures, insurance marketing or logistics services.” If in 2023 the postal business represented around 66% of income of the public company, followed by 24% from parcel delivery and 10% from “diversification” (“new lines of business”), the idea for 2028 is to turn the tables by making these quotas represent (respectively) 49, 35 and 16%. The goal: “Reverse the losses to end the period with an Ebitda margin of 6%, a consolidated profit situation and a healthy financial position.” Are they all challenges? No. The scenario may be complicated, as demonstrated by the fact that Correos can’t quite find the key to gain market share or the challenges it has encountered in its commitment to insurance marketing, but the company still has two good assets. Both closely interconnected. The first is its geographic penetration and vast network of operators and offices. The second, its focus as a “provider of essential services.” … Read more

74,000 years ago, a volcanic eruption led humanity to the edge of extinction. We begin to understand how we survive

by

74,000 years ago, in a remote lake north of Sumatra, a volcano erupted. But it wasn’t a normal volcano. According to archaeologist Jayde N. Hiniak“The Toba expelled 2,800 cubic kilometers of ash to the stratosphere, created a crater of 1,000 soccer fields” and caused a global winter. That could take our species to the edge of extinction: for more than half a century, many anthropologists are convinced that it was that eruption (one of the greatest known eruptions) that reduced the human population to about 10,000 fertile couples. It would be the most critical moment of Homo Sapiens since it arose. It is true that the theory is controversial and the debate around the real climate change that the Toba created is still very alive; However, no one doubts that what happened that day in Sumatra was a huge catastrophe. And that can be seen in archaeological remains. As Hiniak pointed out“Most archaeological sites show a history of resistance.” In areas such as South Africa or the lowlands of Ethiopia these climatic changes led to the adoption of technological innovations such as the development of arches and arrows. In much closer places (such as Indonesia, India or China), the population also suffered deep changes that allowed him to survive. All this can be known because the Toba left many geological samples distributed throughout the world. Studying the deposits before and after the ash of the volcano gives a lot of information on how these societies changed socio-technologically. The flexibility was key. Regardless of what Toba will cause (or not) drastic reduction Of the population, what is clear is that it allows us to draw conclusions about what was the fundamental feature that explains the survival of human communities: behavioral flexibility. Something that allows Image | Tetiana Grypachevska In Xataka | When Newton reached the fundamental laws of physics there was already a sign that said “Leonardo was here”
