Trying to understand why human beings like alcohol so much, these scientists have just found a fundamental clue: drunken monkeys

by

More than two decades ago, Robert Dudley wondered how it was possible that we liked alcohol. In 2014, the evolutionary biologist of the University of California in Berkeley published “El Mono drunk”, a book where he explored The evolutionary roots of that transcultural hobby to alcohol. According to Dudley, it is the fans of primates to fermented fruits (rich in sugars and with a very light alcoholic content) what is behind all this. The problem, as with all the hypotheses of evolutionary biology, was to demonstrate it. Now we have found some tests. Because Science Advance magazine He has just published a study which shows that wild chimpanzees consume the alcoholic equivalent to one or two human cups. That is, exposure to this substance is regular and “probably” was also in our past as a kind, as Dudley said. How have you discovered it? The team analyzed the fruits consumed by the wild chimpanzees in Uganda and in Ivory Coast. Thus, they discovered that these 21 species had a concentration of 0.3% alcohol on average. To the extent that these animals consume about 4.5 kilos of fruit, the amount of ethanol consumed daily is more than the 14 grams that has a standard glass in the US. Of course, “by adjusting for body weight, which in chimpanzees is around 40 kilos in front of about 70 in humans, the exposure equals almost two glasses,” Explain in SINKSEY MARO, main author of the study. It is true, however, that as consumed throughout the day, researchers have not found signs of drunkenness in chimpanzees. So drink alcohol is something natural? This is a usual confusion when we put on the table lAs evolutionary explanationsbut evidently it is not prices. To start because there is nothing ‘natural’ per se. The Natural-artificial ‘distinction It is something that has very little scientific, philosophical or social basis. We have reached a point where everything is artificial. But, on the other hand, the world has changed a lot. Although the hypothesis can explain the origin of the taste for alcohol in all human societies, constant exposure to alcohol of great concentration such as the one we suffer today has nothing to do with that of our ancestors. Therefore, our taste for alcohol may have a certain evolutionary base; The abuse of ethanol and the health problems it causes are something else. Something much more dangerous.

We always believed that the light guns fired invisible rays, but the reality is the opposite: it was the TV that shot

by

Recognize it: if you are old enough to have played withA Light GunFor a while you thought that this gadget worked by firing rays of invisible light that television detected. Was it the position of the gun? The distance? Did the glass of the screen really knew when the goal was in front? Actually the solution was much simpler and ingenious. The light ray is in reverse: the gun is the receiver. Guns of what. First, let’s remember the history of the device: the light guns in video games began to appear in the thirties in mechanical arcades and evolved towards electronic video games in the 1970s and 1980s. Nintendo already experimented with early versions with its video shooting series for famicom in 1984, whose gun was not futuristic, but it seemed like a western revolver With the theme of the game. Nintendo arrives. The device of this most popular type was Nintendo Zapper for Nespossibly because he was accompanied by one of the most iconic games of the genre, ‘Duck hunt’. The Zapper was already tumbos since 1984 with the version for Famicom, but in 1985 it became the Zapper of NES and left in the United States with the science fiction design we know, automatically becoming a pop icon. In 1988 it was redesigned with bright colors to resemble even less to a real weapon and comply with the legislation. There were up to 17 official games for Zapper. In Xataka This genius has transformed the ZNA Zapper is an incredible laser ray gun But … how did it work? Actually the Zapper and the rest of the light guns of the time were not emitters, but light receptors. The process that followed to work was: when the player clenched a trigger, the screen turned black during a Frame. In the following, the objects to which they have to become white blocks, and the rest remains black. The human eye can barely distinguish this pair of Frames Inside the gun was a light sensor that detected if the area to which it was aimed had changed to Blanco. The game determined what objective had been “shot” according to the time in which this white block appeared, since each white objective was sequentially shown in a different frame. And of course, if the sensor detected the white light inside the expected interval, the shot was counted as a success. Only for old people. The ingenious method only worked on CRT screens, as technology depended completely on the speed and characteristics (on the shortcomings, let’s go) on the soda speed of the cathodic tube. On LCD screens, plasmas and other modernities, the delay changes, and so does the soda technology. What makes ancient games “rare” on modern televisions is also what prevents the gun sensor from correctly capturing the light and location of whites. {“Videid”: “X9HMC3A”, “Autoplay”: False, “Title”: “Nes Mini, Review and Spanish analysis”, “Tag”: “”, “Duration”: “250”} More guns. Then, especially in the field of recreational, more sophisticated guns arrived, such as ‘Operation Wolf’, which was actually a command that determined where it pointed according to the position of the gun, fixed in the machine of the machine (a method as ingenious as that of the Zapper, playing with what the player who is happening is believed). And then they arrived, in fact they do in machines that remain in operation, increasingly sophisticated systems, and that use infrared sensors or cameras to determine where the player points out. But the adorable imagination and naivety of the Zapper give him a unique personality. In Xataka | The Nintendo PlayStation exists: this is the history of the hybrid console that never reached the market (Function () {Window._js_modules = Window._js_modules || {}; var headelement = document.getelegsbytagname (‘head’) (0); if (_js_modules.instagram) {var instagramscript = Document.Createlement (‘script’); }}) (); – The news We always believed that the light guns fired invisible rays, but the reality is the opposite: it was the TV that shot It was originally posted in Xataka by John Tones .

They have developed their own language

by

New York and rats is a long story. Also disgusting. But above all it is a struggle without barracks for trying to end a plague that does not stop reproducing from God knows when. Last year the photo was, if possible, a little more tremendous: they were no longer rats, They were super -trarates and a notice for the rest of large cities. In 2025 a red line was reached: they were growing at 300% And nobody had the slightest idea of ​​how to avoid it. Now we have a clue: it turns out that they have their own language. An unexpected emblem. From its origins as new Amsterdam in the seventeenth century, New York has accumulated iconic symbols that identify it in the collective imaginary: the “I ❤ NY” shirts, the pizza, Broadway. But he has also lived with a much less glamorous companion and persistently associated with his identity: The damn rats. It is calculated that today Three million are arounda figure equivalent to a third of the human population of the city, and that are an inseparable part of the urban ecosystem. That ubiquitous character makes them object of study privileged to understand how animal life adapts to the city and how the limits between the human and the wild blur in large urban concentrations. An innovative study. Thus, a team of scientists from New York and Germany it was proposed to analyze the behavior of the Rattus norvegicus New York using avant -garde technologies. Namely: artificial intelligence to identify movement patterns, thermal cameras to follow ultrasonic displacements and recordings to capture their vocalizations. The objective was to verify to what extent these urban rats differed from the profiles described in general studies on the species. The results, published in The Biorxiv platformthey have shown that rats modulate their “language” dynamically, adjusting their ultrasonic chillidos to The intensity of ambient noise that surrounds them. On the surface, in parks and sidewalks, they communicated with less power, while in the bustle of the subway the intensity of their vocalizations shot to be heard among the rumble of trains and crowds. An adapted language. Thanks to deep neuronal networks that allowed to analyze spectrograms and measure acoustic differences, the researchers verified that the vocalizations of New York rats They were of shorter duration and were outside the frequency ranges typically described for the species in other contexts. It was, in short, own languageborn of the need to be heard in a deafening metropolis. One of the researchers, Emily Mackevicius, He related an example Revealing: In the full step of an ambulance, the ultrasonic squeaky of rodents appeared in the spectrogram above the siren, inaudible shouts for the human ear but effective in their universe. The rats, in other words, had learned to raise your voice about the noise of the city. Amazing (or acongojante). Social dynamics. Plus: the Video observations They also contributed keys to the social life of rodents. Young specimens, even in learning of fodder strategies, They moved in a groupin contrast to adults, more lonely. This difference suggests a flexible social structure adapted to experience and the need for protection. The researchers They underline That, beyond the usual cartoon of the New York rodent as a plague, its behavior reveals complex cognitive and social dynamics that deserve to be understood in their own ecological context. The biology of cities. He Rat study New York points to a broader challenge: understanding the biology of urban environments as an essential field of research for the future. If by 2050 almost seven out of ten people They will live in citiesthe interaction with species adapted to these habitats will be, if it fits, more and more intense. Animals that survive and thrive in the city, from rats to pigeons, foxes or mapaches, are not mere uncomfortable companions, but actors of a shared ecosystem. The finding that New York rodents have developed own languageadjusted to the noise of the metropolis, not only illuminates its ability to adapt, but also raises a most disturbing mirror: the city itself molds the voices and behaviors of those who inhabit it, humans and animals equally, in a continuous biological experiment that defines the present and anticipates the future of urban life.

The US launched a pulse to China with the tariffs and China has responded not buying soybeans. It is wreaking havoc

by

China is hungry. We have seen it recently with fish, sweeping sides of South Americawe also see it with The taste for coffee they are developing And with a product very culturally linked to Asian countries: soy. The problem is that the amount of soybeans that produce is marginal (about 20 million tons) and esteem that need between 120 and 130 tons to meet their demand. Who do they buy it? To Brazil and the United States, but with the tariff pulse of recent months launched from the administration of Donald Trump, China has decided that its response would be to make the emptiness to the American soy. And it is causing the silos of the farms to be burst. Brazil and Africa are delighted. Bassoon. To understand the current situation, you have to look a few years ago. Makes one decadeChina was an undisputed ally of the American soybean market. It is estimated that about 40% of the soy of the United States went to China, but with the arrival of different commercial vetoes, things began to change. In 2024, China bought about 20% of its soy to the US. It supposes more than 27 million tons of soybeans with an approximate value of about 12.8 billion dollars, but Things began to twist With the new commercial war. Due to Tariff crossing Applied by Washington and Beijing to their respective imports, there were doubts about what would happen to that star product and if, with high tariffs, it would remain equally appetizing for Chinese importers. We already have the answer. The photo in 2025. From January to July of this year, it is estimated that China imported 16.5 million tons of American soybeans, a ridiculous figure compared to that of previous years. The worst is comingsince a virtually zero soybean import from the United States for the last quarter in which we are going to enter, contrasting with the more than ten million tons in the same period of the previous year. In fact, if in 2024 20% of China’s agricultural imports from the US were only soybeans, this year it is estimated that the figure will remain in 12% imports for all agricultural products. North Dakota. As they point in New York Timesin a typical year, the United States would send more than half of its soy to China, having states like North Dakota that would sell 70% of its production to the Asian giant. With this change of course in the market, farmers face the risk of blockbuster, filling silos, but without the possibility of giving way to so many tons of product. The consequences are what we already know: brutal prices falls, loss of land value and rural economy, while farmers have to continue paying mortgages. In the 2019 commercial war, the administration offered aid to farmers to support the pressure of a China that did not buy them, but it remains to be seen in the near future while senior US and China officials will They gathered This week in Spain to discuss commercial decisions (With Tiktok’s highlight). As NYT points out in NYT report, farmers expect that of soybeans to be one of the issues to be discussed, since there are examples of farms that will lose up to $ 400,000 only this year, being an inasumable situation in some cases. China looks at Brazil. But of course, China is not stopping buying soybeans for both human consumption and for the consumption of livestock, what happens is that they are buying it to other producers. The US is the second worldwide, but above it has someone who is living a totally opposite situation: Brazil. With the commercial war of 2019, China has already begun to diversify looking at the Brazilian market, but these years has been combining both for mere interest: as noted ReutersUSA sent its soy between September and January, before the Brazilian harvest that starred in the rest of the months. In the middle they point out that China has gained soybeans so as not to have to buy the United States this season. HE esteem that the South American soy will cover 95% of the October China demand. Also to Africa. In parallel, China is exploring new origins for soybeans, especially in Africa. Although we talk about modest volumes, imports from Nigeria either Mozambique They have increased in recent months, being part of China’s strategy to diversify, minimize risks and, in addition, invest directly in areas with agricultural potential and in which they can have greater control. Because this strategy is something that we not only see with soybeans, but also with infrastructure both in Latin America (among it, Railways and ports) as in Africawhere they are investing in projects that allow access to critical minerals and metals. It is something that reinforces its position geopolitics in front of the United States while diversifying their sources for ensure stability and continuous supply.

In Spain, a huge electric carload network has been created in the shadow: Mercadona’s

by

The expansion of the electric car depends on several factors. Autonomy is fundamental, but so important is reduce friction when loading. That is why they are applying Wireless load solutionsbut it is also necessary a Expansion in the loading network. And there is someone who has positioned himself as the great network of free cargoers in Spain. Mercadona Short. Loading the car while making the purchase is a comfortable way to give an impulse of kilometers to the accountant. In that sense, Mercadona hill 2024 with almost 5,000 active recharge points if we add the more than 4,800 of Spain and the almost 140 of Portugal. It is curious, but this positions the supermarket as one of the most extensive networks in the country. The network. To reduce that friction, On this website We can see a list of the Mercadona that have recharge points with a breakdown of the most important data: Population and street. Load places. Power. Asterisk. Although the number of recharge stalls That they have deployed in a short time, there is an important detail to consider (not to mention those that park combustion cars in these places focused on plug -in electric/hybrids), it is the loading power. Currently, Mercadona offers two powers: 3.7 kW and 22 kW. They are clearly scarce powers. Load at 3.7 kW for free for 60 minutes. Load at 22 kW at € 0.25/kWh. What Mercadona proposes is a support for that day, with a free recharge of about 15 kilometers of autonomy, enough for daily urban activity, hugging the CA network while rejecting, for now, the fastest stations of CC. It is also important to take the cable in the trunk. And model. The good market is competition, and if other chains see that users perceive Mercadona chargers as an important value added to experience, they will begin to offer their own solutions. Carrefour, for example, too It has a map in which we can find loaders of a much more limited network, but with options of 50 kW and 150 kW. Savoramás has projects Undergoing to expand its network by EDP and Lidl has More than 215 stores with 654 recharge points in total with Compatible loaders With Chademo, CCS and AC type 2 and free recharge for half an hour, but without a detail of what type of speed is handled in each of those chargers. And the English Court more of the sameeven with some exclusive points for Tesla. As we say, in the end it is a way to reduce friction when betting on the electric car, but beyond supermarkets, we see that little by little the network is expanding in stores such as Decathloneither McDonald’swhere We have seen some Ferrari by throwing morro. In this case, with powers up to 150 kW. Images | SMNT, Carloss In Xataka | Installation of an electric car charger in neighboring communities: step by step, legislation and everything to know

This is the recipe with which they want to turn around the energy map

by

Against all forecast –And in the middle of Trump was in the White House– California is demonstrating that the sun can with the night. The recipe has no technological mystery: a lot of photovoltaic, many batteries and an increasingly fine demand management. The result is that natural gas, for decades the king of the evening peak, yields ground quickly. The key is in batteries. And the state of California is more than clear. The solar generation has increased in this half year by 18% compared to the same period last year and the discharge of batteries grew by 63%, allowing to cover up to a third of the maximum night demand, According to Ember. That cocktail allowed to cover the maximum night demand, a space that until nothing dominated the combined cycles of gas. The impact has been fulminant: the production of gas plants fell 25% in one year and 43% in just two. During the summer, in 41 of the last 49 days, the Californian network was able to meet the entire demand exclusively with solar, wind and hydro, sometimes for more than nine consecutive hours. In several days, the renewable supply exceeded 140% of the demand, with surpluses exported to neighboring states, As explained by Professor Mark Jacobson in an interview with Bruce McCabe. The kitchen of success. The key to the Californian turn can be summarized in a word: capacity. In just four years the state went from having 0.6 GW of batteries at a network scale (2020) to 11.7 GW in 2024, almost half of the entire National Park. That year it installed more storage (3.8 GW) than large -scale solar (2.5 GW), a milestone that reflects the change of priorities, as they have detailed in an Ember report. However, we are not talking only about the hardware of the matter. The Caiso operator He opened the door that the batteries arbitrate intra -diagram prices – cargar when the energy is abundant and cheap, sell in expensive hours – participate in regulation services and reserve part of their capacity for the so -called “critical hours” in the afternoon. In 2024, even with more moderate price peaks, its role in the Net-Peak was consolidated, displacing the gas turbines that used to dominate that section. Two factors that have helped. On the one hand, solar roofs already produce the equivalent of 13% of the electricity sold in the state, reducing the daytime demand of the network and, when combined with domestic batteries, also the nocturnal. On the other hand, the Demand-Side Grid-Sport (DSGS) program has given rise to one of the world’s largest power plants in the world, with more than 200 MW operations and 720 MW of customer batteries. In the summer of 2024 it was activated 16 times during heat waves and tested its stabilizer effect. However, its future is uncertain: the state budget deficit and a cut of 18 million dollars put both DSGS and the Microredes Deba program at risk, warns PV Magazine. The impact on prices. The most immediate result for consumers is that prices have relaxed. The renewables sank the wholesale cost: the spot fell 53 % year -on -year and many noon sections recorded negative prices, damping thanks to the fact that the batteries already absorb 15 % of the demand in those hours. According to Jacobsoncomplete electrification can save between 60% and 65% of the annual energy invoice compared to the current fossil -based model. All pink color? No, California still faces challenges. Demand response programs depend on public budgets that are not guaranteed. As Jacobson has pointed out In a study published in Standfordthe network needs to continue improving its flexibility: move hydroelectric to the night, accelerate marine wind and strengthen demand management are essential steps. Spain: The other face of the currency. While California wins the gas battle, Spain lives the opposite paradox: it produces more renewable than ever, but cannot only trust them. After the blackout of April 28, 2025, Red Eléctrica activated a reinforced operational mode which prioritizes combined cycles. The problem is not the lack of sun or wind, but storage and flexibility. Without enough batteries or hydraulic pumping, the network lacks mattress to transfer the noon surplus at night peak. The Government knows and has reacted with an “antiaps insurance”: Royal Decree-Law 7/2025 He opened the door to capacity markets that remunerate firm technologies for being available. The objective is to maintain 9,000 MW of combined cycles that were at risk of closing. But those are temporary crutches. Structural solutions – batteries, hydraulic storage, micro -redes and demand management – will take at least until 2026 to deploy. Two roads, the same lesson. Mark Jacobson He foresees California will reach 80% renewable between 2026 and 2028 and 100% between 2030 and 2033. Ember He estimates that in 2025 A batteria GW will be installed for every 1.7 GW of solar, further accelerating gas replacement. The moral is clear: California demonstrates that miracles or futuristic technologies are not needed: with solar, wind, hydro and batteries enough to bend gas. Spain, on the other hand, remembers that the transition is not improvised: without sufficient storage or management, renewables cannot sustain the network alone. The road is clear; The question is who will travel faster. Image | Rawpixel Xataka | 99% of the Internet travels through submarine cables.

70 years ago the United Kingdom took the most remote islet in the world to frustrate the USSR. Today is a huge headache

by

Rockall is a sharp stone in the middle of the Atlantic. Literally. Small, inhospitable, isolated, The islet It seems molded on purpose to repel any human presence. No one lives there and the few adventurers who have challenged the island, tried to spend as long as possible on their surface, have endured as much a month and a half. However and despite all that, Rockall stars in an exciting story that Even today It is marked by the controversy. After all, it has gone from being an important piece for the national defense of Great Britain (and the whole of NATO) to an important economic asset. In a (remote) place of the Atlantic … Throughout the Atlantic there are countless islands, archipelagos and rocks, but few are as inhospitable as Rockalla small rocky promontory of the North Atlantic. He arrives with reviewing a few data to get an idea of ​​to what extent he is isolated and is the last place on the planet in which one would want to spend his vacation. Rockall is among the coasts of Scotland, Ireland and Iceland, hundreds of kilometers from anywhere inhabited. To find houses and population you have to look at 370 kilometers From there, a NORT UISTin the Exterior hebrids (Scotland). “The most isolated rock”. It is not just that Rockall is far from everything. It is directly thought to repel the presence of humans. The islet measures only 25 meters wide and rises 17 m above sea level, which explains that its slope is often shaken by the waves of the Atlantic. There is no one to live there, but the few people who have tried to try their luck have encountered an inclined and rocky surface, a granite block in which there is hardly any space of 3.5 x 1.3 m level enough to stand. In the middle of the last century the British naturalist James Fisher described Rockall as “the little most isolated rock of the oceans of the world.” Even more graphic was a few years ago Lord Kennet, torque and exmarinero than He referred to the islet as the “most desolate, most despair and more horrible” place on the planet. The person who has spent more time on his sharp rocks was the surveyor Nick Hancock, who endured 45 days on its surface. A few years ago a teacher and veteran of the British army wanted ‘Solo’ a month. A rock with an intense story. Given its characteristics, one might think that Rockall is a rocky point without any interest in the middle of the North Atlantic, an islet away from political debate or territorial disputes. Not at all. Its history can go back several centuries agobut he became especially intense in the mid -XX. It was then, at the end of the summer of 1955, to be more precise, when Queen Elizabeth II authorized the annexation of the islet and ordered the British Royal Navy to “take possession of the island.” That same year, Remember the BBC chaina commander reported the successful “conquest” of Rockall. An indomitable island. That episode has already demonstrated how indomitable the rock islet is. The HMS Vidal, a recognition ship by the British Royal Navy, arrived in the area on September 15, 1955, but the sailors It took several days to be able to raise your flag. The reason: the very strong and violent wind gusts. The BBC Slide which was the last territory claimed by the British Empire. Years later, In 1972Parliament voted in favor of incorporating (already formally) Rockall into the United Kingdom, integrating it into the Western Islands of Scotland. But … why? 70 years ago Rockall was the same inhospitable, uninhabited and isolated rock that is today, so why the hell was Great Britain interested in his possession? What was lost there? To understand it you have to keep in mind the complicated geopolitical map of the 50s, In full cold warwhich conferred to Rockall a special value. With the NATO submarines and the USSR patrolling the North Atlantic, its possession became a festive issue. Not just that. Rockall may be isolated from everything, but less than 400 kilometers from there, in the exterior hebrids, London had its first Test field For American guided nuclear missiles. The islet may be hell on Earth, an sharp rock in which it was impossible to live more than a few weeks, but … what if “hostile agents”, as spies at the service of Kremlin, managed to settle in the area to monitor British tests? Beyond the Cold War. The USSR collapsed in the early 90s and London’s priorities in defense became others, but Rockall did not lose interest. Of course: this went from the military strategy to the field of economy and resource management. On the island the geologists identified a special type of granite, but if for something he stood out it was the potential of their marine bed and its waters. They interested their possible oil reserves. And interest (and much) the fishing richness that hid their waters, where rappes are captured, North Gallo, haddock or squid, among other species of high value. The problem is that this wealth not only interested London. He also did Islandia or Ireland. A headache. In 1982 the United Nations Convention on the Law of the Sea (Convent) established that rocks without population or economic fabric, as was the case of Rockall, could not be used as a basis for territorial claims. In other words, the islet could no longer be used as ‘key’ to argue the theoretical legitimacy of the United Kingdom over the surrounding waters. However, a Google search arrives to verify that in recent years law and fishing in the area have been a reason for friction With Ireland, Iceland or even Denmarkas representative of the Faroe Islands. The ‘Roces’ of 2019. One of the most tense episodes was lived before the pandemic, in 2019, when Scotland warned the Irish ships on the “illegal” drag fishing that … Read more

China is making time its best resource. Its rapid iteration is unique

by

China has open fronts in practically any technological fieldand in recent years we have seen how the country has opted in a mastodontic way in areas that could decide its position in the next decade. The Asian giant knows that time is one of the most valuable resources in the digital era, and therefore its digital manufacturing ecosystem and ultra -grape iteration is changing the rules of the game worldwide. A silent revolution. What took months to develop now is completed in weeks. The medium baiguan I explained it Through a visit to the facilities of a Robotics Startup, where it indicated that modifying a structural component at an early development stage required opening molds, a process that could cost about 200,000 yuanes and several months of waiting. “The development cycle, which used to last between one and two months, could be shortened one week or a few weeks with the help of digital manufacturing and 3D printing,” assured The medium. The processes now allow multiple iterations in the time that took time to complete one. The perfect speed ecosystem. In this sector, China does not dominate just by having cheap 3D printers manufacturers. According to the medium, its real advantage lies in an integrated ecosystem that includes ultra -efficient logistics networks, interconnected software and hardware suppliers, and a delivery capacity that allows to close the market feedback cycle in record time. The medium Point out To the Miniso company as an example: from design to sale, the entire process is digitized and can be completed in a week. Figures. Between 2015 and 2022, China’s additive manufacturing sector grew by 30% per year, According to Am Research. The firm specialized in market analysis projects that the country will obtain revenues of about 8,000 million dollars only in 3D printer sales by 2032. To put it in context, China represents 50% of the global industrial robots installation, compared to 25% in 2015. Companies like EPLUS3D have already developed metal printers with up to 64 laserssurpassing Western competitors such as Nikon SLM Solutions, who stay in 12. Cheap labor costs, yes, but there are more. For years we have thought that Chinese competitiveness was based solely on economic labor or flexible regulations. However, Baiguan appointment Its extraordinary digital capabilities, flexible supply chains and ultra -grape mechanisms for market feedback. From Roborock to Pop Mart, Chinese companies are gaining global market share not only for being cheaper, but for iterating faster. The challenge for the West. China allows companies to deduce 200% of their R&D expenses for taxes. As Point out Forbes, the United States reduced that 100% to 10% deduction in 2017. In addition, it must be taken into account that Chinese companies not only dominate their domestic market. And as explained by the media, China is engaged by opening offices both in Europe and the United States, offering cheap significant equipment without sacrificing quality. China uses time in its favor through the development of new technologies, and it is the same time that will tell us where the country will be located in the next decade.

Space station astronauts have made sushi. In Japan they would open a war advice, but it is fantastic

by

Sushi and ramen are to Japan what the potato tortilla –With onion– Or Paella to Spain: a sign of cultural identity. They have more complex origins than we think: while ramen derives from Chinese cuisine, Sushi was born as a conservation technique before transforming into a gastronomic icon. To such an extent that to International Space Station Astronauts He has given them to prepare Sushi with what they had at their disposal. It has come out regular, but at the same time it is fantastic. Space food It is not a secret that space food You must have very specific characteristics. It is mostly lyophilized And it is thermosellated. Before consumption, the one that is not ready to consume, must be rehydrated and any food and ingredient that enters the season You must meet a series of both security and cleaning requirements. Conservation is also very important for obvious reasons And, although we can think that it is not good, The problem is usually astronauts. When cooking (among many quotes that cook), an ingredient as important as the food and condiments of the station is the double -sided tape. In numerous videos We have seen how ingredient boats such as honey or simple scissors are glued with that tape to the station surfaces. Sushi at the space station. Occasionally, one of the US members decides to surprise his companions cooking something out of the menuand Jonny Kim’s attempt has been one of the last examples. NASA American and Astronaut, hung A few weeks ago a photo in which a tray could be seen with an attempt at Sushi. To do this, they used precooked rice, fish, spam (A canned meat mark) and a touch of GOCHUJANG (A spicy paste based on rice and chili) and Wasabi. The humidity kept the ingredients glued, but for the tray and the rest of the elements, they used the aforementioned tape. Nostalgia. It is not the most appetizing sushi in the universe and, surely, Japan would have some questions for the architects of this culinary crime, but there is a great “but”: as on earth, this space sushi served for one thing: unite the members of the station. Up, despite fellowship, loneliness must be quite present and one of the astronauts commented that he missed the sushi. That gave them an idea: see what they had in their personal provisions to see if they could elaborate something similar. The result is obvious (rice with things on top), but the important thing is that “the result was a great meal,” as Kim points out, and served to foster that feeling of companionship and reduce, a little even if it is, that nostalgia. Nori algae. In X, someone He pointed out What would have been great to use Nori algae To wrap the sushi, but that he understood that it should be difficult to need a dehydrated version of it and that it would not be nice to have algae scales floating around. Kim replied that, in fact, they have Nori, but it is an ingredient that is part of the space orders that, with a limit, can do. And that he had run out of the ingredient. On the problem of the scales, everything is designed: “The crumbs accumulate in the air entry filters, which are aspired every week.” It is not the first time. It is a beautiful gesture, but it is not the first time that sushi is made at the station. It was not a photo, but a complete video that the Japanese astronaut Soichi Noguchi put on the chef’s hat for prepare A somewhat more “traditional” sushi with tuna, Nori and frozen scallops that had risen on board that intention. The reason for that elaboration was the same as that of this summer: surprise his teammates, take care of those ties and make the stay to thousands of kilometers of his homes is somewhat more cheerful. Also One way that missions are more bearable. In Xataka | Until the 90s nobody in Japan ate sushi with raw salmon. Until a marketing campaign changed everything

We knew that coffee was good for health, but now we have discovered that it is a great ally of our microbiota

For years, coffee has not been too well considered. It depends on the place and the historical momentbut the culprit was not so much coffee itself … as caffeine. Although the evidence has managed to deny them, there is still A lot of myths about caffeine and its effects. But something that is also making clear research is beneficial effect of coffee on the body. It depends on the type of tan, of course. And one of the studies More recent links coffee with the intestinal microbiota. Directly, it favors the Bacteria growth in our body. And it is something that fulfills a vital function. The community Microbial of coffee. As we say, different studies on coffee allow you to have discovered your beneficial effects on cardiovascular diseasesthe diabetes or your Effect on the kidneys. In parallel, a relationship between coffee intake had been observed with the increase of certain intestinal bacteria, but the studies were on a small scale. Now, in Nature Microbiology he has Posted a study in which the genomic sequence of the intestinal microorganisms of more than 22,000 people in the United Kingdom and the United States was investigated. They have discovered that coffee drinkers had a different microbiota, with intestinal bacteria such as Lawsonibacter asaccharolyticus Eight times more abundant in the microbiota of coffee drinkers than in those who do not ingest this food. And what does that imply. It is not limited to that bacteria, since increases in irmicutes, actinobacteria, actinobacteria were also observed, PREVETELLA, Faecalibacterium and Bifidobacterium, All of them linked to beneficial metabolic effects, such as greater production of short chain fatty acids. What this means is that, thanks to its polyphenols and the soluble fiber it contains, coffee produces some Prebiotic effects that have a direct influence on beneficial bacterial growth. Before I said that it is something that fulfills a vital function, and in this case it is not an exaggeration. Intestinal microbiome bacteria They fulfill functions such as facilitating digestion, strengthening the immune system, regulating inflammation or protecting against pathogens and diseases. Very direct effects of this includes the production of vitamins and enzymes that are not obtained from food, facilitating Digestion of compounds as fiber and starch or Immune system regulation to distinguish between harmful and benign organisms. Four cups. Tim Spector is one of the experts who has supervised the article and, as my colleagues from Straight to the palatethe amount of optimal coffee would be between two and four cups a day. It all depends on the organism of each one and tolerance, but something interesting is that we not only obtain those benefits for the microbiota, but also a a large amount of fiber. Specifically, 1.5 grams of fiber for each cup of Filtrated coffee (There are many ways to prepare it, but filtered or infused is one of those that allows to extract more nutrients), and it is an amount similar to what would be obtained when eating a tangerine And the caffeine, what. And this of the tolerance that each one has to coffee is important because there is a “Limit” in the amount of caffeine That we can take up to be in the healthy segment, but it depends a lot on each person. The good thing is that these positive effects on microbiota have been reported both in the ‘normal’ coffee and in the decaffeinated. If milk is addedIn addition, the amount of polyphenols may slightly decrease, but the balance is still positive. What should not be added is sugarsince there we would be doing more bad than good. But if decaffeinated coffee is consumed, you should have an eye on how the process has been performed. Not all decaffeinated coffees are the same because there are several ways to eliminate (which is not completely eliminated, but is considerably reduced) caffeine, and Not all are equally healthy. To the point that some methods They are under the radar of organizations such as the US FDA. Image | Justin Bhalla In Xataka | There are more and more studies that link coffee with living more. And it is very easy to put the leg when preparing that ‘philosopher’ coffee
