The San José Galeon sank in 1708 with a treasure of 20,000 million. A handful of coins has revealed its destiny

by

Throughout the planet it is estimated that there are close to three million Of pecios, vessels that caught in their day and now rest at the bottom of the oceans, turned into sentences of marine life. This list is included from transatlantic as The Titanic to destroyers of World War II, abandoned boats or colonial caravels. Few arouse the interest of San Joséthe galleon sunk in 1708 off the coast of Colombia with the wineries full of gold, silver and gems, a treasure that some value in almost 20,000 million of dollars. His exact whereabouts was a mystery for centuries. Now Colombian archaeologists believe Having located it without a doubt thanks to a track that confirms the opulence of his treasure: the gold coins that he transported on board. A Milmillonario Treasury. In his day the San José was an imposing galeon, a large ship of 40 meters of length12 of manga, three masts and 64 cannons built in Guipúzcoa commissioned by King Carlos II. Your mission: work on the Indian fleet. Neither its power nor its dimension avoided however that the history of San José was brief. The ship ended up sinking from the coast of Colombia in June 1708, only a few years after its launch, beaten by the cannons of a squad of British privateers during the Battle of Barúin full war of Spanish succession. The most curious thing is that the legend of San José began just then, after its shipwreck. And the reason is simple: in addition to a crew formed by hundreds of sailors, the galleon loaded with gold, silver and gems, among other treasures. There is talk of a loot of 200 tons that today would reach a value of billions of dollars. Some estimates place it in 17,000 millionothers in more than 20,000. There are also those that reduce that calculation, but without leaving the land of the thousands of millionsan imposing treasure. And where is the San José? For centuries that was the great unknown. It was known that the wreck was In the Colombian Caribbeanbut … where exactly? What were your coordinates? In 1981 A company announced to hype and saucer having found the Galeon and allegedly delivered the information to the government in exchange for keeping a part of the treasure, but the story soon complicated. In 2015 The country’s authorities claimed to have located the remains of the Spanish ship in a different place, which tightened the disputes about who has the merit of the finding and (more importantly) the rights over the treasure. The big clue: the coins. Historical discoveries often depend on small details. And underwater archeology is no exception. Although experts have been convinced that the vestiges resting in front of the Colombian coast are the remains of San José, a New research published in Antiquity He has just reaffirmed the identity of the wreck. And in a fairly peculiar way: analyzing the gold coins located in the underwater deposit, at approximately 600 meters deep To get it a Colombian team undertook Between 2022 and 2024 Several expeditions focused on the remains of the wreck. He did it With the help of a rova non -manned submarine vehicle that allowed experts to obtain high resolution photos of the coins that rest on the site. Thanks to techniques such as The photogrammetry They were also able to draw a three -dimensional reconstruction of the wreck and several models and digital replicas of the environment. And what did they discover? They found Macuquinashand coined coins and that were used for more than two centuries in the trade of the Americas. With the help of high resolution photos taken in situ – the Colombian Institute of Anthropology and History assures That no object object was extracted – experts discovered that the pieces have an average diameter of 32.5 mm, weigh 27 grams and are coined with revealing designs. On the obverse, the coins show a variant of The Jerusalem Cross (A large cross with four smaller) next to a shield with castles and lions, symbol of Castilla y León. On the back they carry the Hercules crowned columns On waves, which relates the pieces to the Lima Mint. Squeezing clues. They are not the only clues identified by archaeologists, who have identified a “L” that seems to refer to Lima, an “8” that shows the value of the currency and an “H” related to the brand of Francisco de Hurtadohe Major trial of Indies in 1707. In the central part of the coins the legend “PVA”, “Plus Ultra” is also appreciated, a wink to the maritime expansion of the Spanish monarchy. The information is completed with three digits (707) located at the bottom of the pillars, a reference to the year in which the coins were coined: 1707, just before the San José sink into the Caribbean. Why is it important? Because all these data are clues that help to better understand the site and the circumstances in which the galleon that rests there. “Unraveling the characteristics of the currencies helps to determine the age and origin of the wreck”, collect the article. “First, it establishes a temporal frame: the sinking had to occur after 1707. This, along with other tests, such as the presence of Chinese porcelain Kangxi And inscriptions in the cannons dating from 1665, suggests that the ship sank at the beginning of the XVIII. “ “Corroborate identification”. The coins also give clues on the route that must have followed the sunken galleon. “In the Viceroyalty of Peru, several gold mines were registered, mainly in Puno and Huamanga. It is likely that the material to coined the coins would be obtained from these mines and processed in the house of La Moneda de Lima, which resumed operations in 1683 and began to coined gold in 1696,” Experts reveal In your study. All those evidence, added to what historians already know about colonial history, leads them to A resounding conclusion: “The set of tests corroborates … Read more

We had been thinking that creatine served to train better. It turns out that the greatest benefit was in the brain

by

Creatine is the star sports supplement and one of the most studied. As with the coffee and caffeineis surrounded by Myths And we have been investigating its benefits for decades when practicing sports. AND studies More recent have placed up to creatine supplementation by pointing out that the muscles are not the only ones that benefit from their effects. The brain also appreciates it. Physical performance. Creatine is a nitrogen compound that occurs mainly in the liver and that humans also obtain through the consumption of meat and fish. Although there is controversial studies in this regardcreatine really is stored in the form of phosphocreatine, acting as a booking Immediate energy. This means that, when the muscles are subject to intense efforts such as a sprint or a weightlifting, phosphocreatine acts to regenerate the essential energy molecule for muscle contraction. This allows muscles to maintain high performance for a little longer. It also increases cell hydration and stimulates protein synthesis that leads to cell growth. Enhancing the brain. Being such an studied supplement implies that numerous ways have been found in which creatine benefits our body, reducing inflammation, oxidative stress and muscle catabolism. And, along the way, they have found benefits additional that have not to do with the growth of our most ‘visible’ muscles. It is increasingly recognized for its general health benefits, including cognitive function and healthy aging. Although the brain is not a muscle, it also stores creatine and can benefit from its energy effects, such as supplying energy quickly to neurons. A applicationfor example, it is the good brain function in times of lack of sleep. Essential. This is something observed in several investigations, being carried out by the team of Dr. Richard Kreider, director of the Exercise and Sports Nutrition Laboratory of the Texas A&M Universityone of the last to contribute to the conversation about its benefits. According to Kreider, the regenerative paper and as a rapid “fuel” is relevant for both muscle and brain. “When the body is stressed, as in exercise or in metabolic conditions such as those caused by some diseases, phosphocreatine is needed to maintain cellular energy,” says Kreider. Neuroprotection. Others studies They point to added benefits, such as acting as a neuroprotective, helping in the recovery of brain injuries and showing potential to reduce mitochondrial dysfunction, key factor in neurodegenerative diseases. It also helps reduce the feeling of tiredness, maintaining alert and performance in demanding cognitive tasks. How much? One of the big questions when creatine begins to be taken how much is necessary to fulfill its function correctly. It has been experienced with several doses and there is a kind of agreement that would have to be taken between 0.07 and 0.1 grams per kilo of weight per day to optimize physical performance. For a 70 kilos person, this is equivalent to 5-7 grams per day. Kreider fits those accounts by resorting to that ‘cycling’ practice that was recommended a few years ago. Thus, the researcher indicates that about 20 grams would have to be taken daily for a week to “help load the muscle”, but later it could be taken between 5 and 10 grams a day to maintain creatine reserves that contribute both to the muscle and the brain. In Vegans and vegetariansIn addition, it is essential because for a omnivore It is difficult to fill the phosphocreatine reserves with your diet, not consuming meat or fish the difficulty is even greater. Security. Due to the myths that we commented before (such as hair loss or that it is an anabolic substance, among many other discharges about creatine), it is easy for people to not trust this supplement. Kreider states that “there is absolutely no data that supports any negative side effect reported anecdotally on creatine,” reaffirming that it is “safe and important to all, not only for bodybuilders and athletes.” Images | Xataka, Scientifanimations In Xataka | Tell me what color is your banana and I will tell you what it is for: the importance of maturation point at nutritional level

Quantum computers threaten encryption technologies. This is the reason why we do not have to panic

by

This month is being very exciting for enthusiasts who follow up the current Quantum computers. Xanadu, a young Canadian company founded in 2016, has announced that Plan to have ready before 2030 A quantum computer of one million photonic ulna with error correction. However, it is not the only company that intends to make this milestone come true. IBM plans to make available to its customers in 2029 ‘Starling’its first large -scale quantum computer endowed with the ability to amend your own mistakes. The main problem facing quantum computers in the field of error correction is noise, understood as the disturbances that can alter the internal state of the cubits and introduce calculation errors. In any case, if finally the correction of errors comes to fruition the prototypes of quantum computers that we have currently will leave behind their status of prototypes and allow us to face really significant problems. And presumably Bitcoin encryption and other cryptocurrencies will fall. We are facing a worrying challenge Quantum computer experts have known for several years that quantum computers They will end classical cryptography. That moment came in May 2024. A team of researchers from the University of Shanghai (China) led by Professor Wang Chao used a quantum computer D-Wave for I successfully violate the SPN encryption (Substitation-Permutation Network), which is a cryptographic algorithm that is used to encrypt information. This encryption is the cornerstone of, for example, the AES standard (Advanced Encryption Standard), which is used a lot. These scientists published the result of their research in An interesting article entitled “Public Cryptographic Attack Algorithm based on quantum processing with the advantage of D-Wave”. However, this is not all. And it is that in the middle of May several Google researchers They published an entry In the blog dedicated to the security of this American company in which they support a crucial premise: an integer RSA (Rivest – Shamir – Adleman) of 2,048 bits can factor in less than a week with a quantum computer of less than one million cubits. An RSA integer of 2,048 bits can be factor in less than a week with a quantum computer of less than one million cubits Bitcoin, Ethereum, Solana and the other modern cryptocurrencies use a cryptography technique known as elliptical curve that is more robust, efficient and difficult to break than RSA, but its mathematical foundations are similar to those of the latter encryption algorithm. In fact, according to Google scientists signed by the article that I have mentioned above, if the future quantum computers will cost them less than initially breaking the RSA encryption, the cryptography of elliptical curve will also fall with relative ease. So far we have talked about cryptocurrencies, but it is crucial that we do not overlook that encryption technologies have a fundamental role in our daily lives. In fact, WhatsApp and Telegram use them to encrypt our messages; Banks turn to them to Protect our transactions And every time we buy something on the Internet, it is the encryption that is responsible for protecting our credit card information. These are just some of the applications of this technology. Keith Martin, professor of the Information Security Group at the University of London (England), has published in The conversation An interesting article in which it addresses this topic. And it reminds us of something important: the threat of quantum computers to encryption technologies is very real, but we have no reason to panic because many researchers have been working on the solution to this challenge for several years. In fact, most of the theoretical work is already done. In 2024 the National Institute of Standards and Technology (NIST) of the United States published an initial set of standards that includes a post -mecuantic keys exchange mechanism and several postcuantic digital signature schemes. The work that is already done invites us to anticipate that at the time the relevant quantum computers appear from a cryptographic point of view Technologies will already be ready They will be able to protect our information. And in all likelihood these techniques will also be in the hands of quantum computers, such as Juan José García Ripoll holdsResearcher at the Institute of Fundamental Physics of the Higher Council for Scientific Research (CSIC).

Drinking a glass of water before eating is one of the most common “tricks” to lose weight. Science has something to say

by

With the summer just around the corner, many people seek to lose weight quickly. We have seen it with challenges like Skinnytok, Shots of vinegar either Liquefied Céspes. In the midst of so many “miraculous solutions”, there is a advice that stands out for its simplicity: drinking a glass of water before each meal. It sounds very easy, but is it another myth détox or is there something true? A glass of water. At first glance, it looks like a quite simple premise. Drinking water before eating can “favor satiety” and help eat more conscious way, as the media have explained as Telva either Vogue. In theory, when occupying space in the stomach, water would reduce the feeling of hunger. But like He has warned Dr. Robert H. Shmerling, of Harvard’s Faculty of Medicine, in an article for Harvard Health Publishing, “human physiology rarely follows such simple rules.” Science behind. Dr. Shmerling He has evidenced That it was a premise “too pretty to be true.” In his article he has detailed that although drinking water before meals can generate a mild fullness of fullness – to activate the stomach mechanoreceptors – the effect is limited and passenger. In fact, as you have continued arguing, some studies support the idea in older peoplethere is even evidence that suggests that, within a hypocaloric diet, who drink water before meals can lose more weight in 12 weeks than those who do not. However, there is a nuance to take into account and that is that There is no robust evidence of long -term effects or in large populations. And other associated theories –Like cold water burns calories by thermogenesis– They have been denied in recent studies. Where there is consensus. The point is not in so much to drink extra water, but in what is stopped. Changing soft drinks, energy drinks or alcohol for water can have a real effect on weight loss. According to May Clinicthat simple gesture reduces the total consumption of calories without conscious effort. In addition, staying well hydrated improves physical performance, exercise resistance and recovery. Not because water “weights”, but because it helps sustain a more active and healthy lifestyle. The shortcut culture. The popularity of tricks like this also responds to a social need: to find fast, simple and effortless solutions to a complex problem such as weight control. In a society obsessed with thinness – especially among young women – they proliferate The calls Life Hacks that promise immediate results. As He already explained for Xataka The psychologist specialized in TCA, Sara Bolo, the worrying thing is that many of these tips end in apparently “healthy” behaviors, but hide eating disorders. It is simply water. In a context where “fast tricks” abound, it is advisable to remember that, as Dr. Shmerling has summarized: “If you think it works for you, there is no damage. Remember that no glass of water replaces a balanced diet.” Image | Unspash Xataka | Nostalgia for the 2000s has brought something else: the obsession with flat belly and radical thinness

convert email into a list of tasks

by

The email, that novelty relic whom no one has been able to kill, is about to suffer its greatest metamorphosis. Hotmail or Gmail They brought storage and search capacity, clients of third parties such as Spark introduced a new way of managing them. What is coming is deeper: AI is making The mail goes from being a writing activity to a decision activity. To write answers to mark boxes. The first systems are already here: Gmail summarizes long threads and develops basic ideas. Outlook suggests short answers. Apple Intelligence summarizes, rewrite and expand paragraphs. Spark Directly take your previous mails to emulate your voice and generate answers with your style. It is just the prologue. When this goes more, We will stop writing most mails, we will simply approve a proposalor we will clarify it. Or we will choose between certain options. In the future, our mail clients will present each mail not as a text to read, but as an action proposal: Accept meeting Thursday at 11:00 a.m. Thank information and ask for more details. Decline proposal. A touch and ready. It is an inevitable change because in the background mail has always been a task management system disguised as communication. Most professional emails ask for something: confirmation, information, decision, action. The AI ​​simply naked this reality, eliminates the liturgy of forced courtesy and repetitive writing. I have written thousands of times “thanks in advance” or “good weekend.” The machine can do it for us. Even in our style. And it will free us from That corporate slavery For what really matters: decide. The end of the game will be something we already anticipate: Bots talking with bots. As Mg Siegler points outthere will come a time when the AI ​​will automatically schedule that meeting with the AI ​​of your contact, will negotiate dates, send reminders, will write the subsequent act, even ask how your child after the operation, perhaps. Humans We will appear for decisions that really require human criteria (Some will also want to delegate that, but It is another topic). And the mail will not disappear, but it will largely be somewhat invisible. And by automating routine communication, we will recover the communication that is worth it.

This is one of the best ways to quickly collect the suitcase at the airport

by

A year ago my Magnet colleagues published an article that focused on the opinion of an airport employee and that I mentioned whether or not to tie ribbons, place stickers or use keychains for Recognize the suitcase When traveling by plane. Are they effective? Yes. Are they recommended? Not so much. The problem is that these stickers, ribbons and other accessories can cover the stickers that airports provide to identify suitcases with our data and reach their destination. If these stickers are covered, the suitcase can be lost. It is not necessary to complicate too much to find a simpler and more effective solution to recognize our suitcase and have it located at all times. The locators of the different brands are very useful for those moments when we leave the plane and want to collect the suitcase. Airtag is one of the best known, But there are many more that are also very practical. AIRTAG by 31.99 eurosthe Apple locator for iPhone users. Samsung Galaxy Smarttag2 by 20.99 eurosan AirTag alternative for Samsung mobiles. Tile mate by 60.29 eurosa game of three locators compatible with iOS and Android.

An old island has been discovered by accident under the sea full of rare land. The problem is that it has no owner

by

We are approaching a point where to say that rare earth moves the world in general, no Only the technological oneno longer sounds so hyperbolic. It happens that a single nation has most of the cake right now. We already said it, China has built The most elegant economic power lever in modern history with those desired minerals. Hence, the rest of the nations strive to find the new “gold” where there is a track, however small. An underwater island has emerged as possibility, the problem is for whom. An accidental finding. The story began when an international team of scientists discovered that a part of the known underwater highlands Like Rio Grande Riselocated about 1,200 kilometers from the coast of Brazil, it was actually A tropical island Tens of millions of years ago. Although training was already known by the scientific community as a chain of volcanic mountains submerged from The late cretaceousthe New research revealed that their western part was once above sea levelforming a terrestrial ecosystem that gradually disappeared under the waters due to tectonic activity and the weight of the accumulated volcanic rock. Revelation not only transforms the understanding of the paleoclimatic geography of the region, but also opens the door to a possible International dispute for its valuable mineral resources. The keys of the past. The discovery began in 2018 when British and Brazilian scientists noticed that certain rocks in the marine bed of the Rio Grande Rise They showed an unusual composition, more similar to lava deposits and terrestrial red clay than to marine formations. Published subsequent studies in Scientific Reports They confirmed that this clay (rich in kaolinite, hematite and goetite, typical tropical soil minerals) was not only a rarity in the oceanic background, but an unequivocal evidence that this segment of the high plateau was emerged between 44 and 47 million years agoduring The Eocene. With a very high chemical alteration index (93), these clays reveal an intense subaéreal weathering and a warm and humid climate, with implications that go beyond geology: the island could have been a stop point For migratory birds Between South America and Africa, offering one more piece in the puzzle of the biological exchanges of the past. A mineral treasure. But there is more, of course. Beyond its scientific value, the Rio Grande Rise houses an invaluable economic wealth. Their Ferromanganese scabs contain high levels of Essential metals As cobalt, nickel and lithium, all fundamental for the global energy transition, from batteries for electric vehicles to wind and solar energy storage. However, what attracts the most attention is your rare earth concentrationespecially the ititrium, a whitish and soft metal used in strategic technologies: aerospace alloys, superconductors, industrial lasers, LEDs and precision lenses. In a context where China overwhelmingly dominates the extraction, refined and manufacture of these materials (with Up to 90 % of world production), any new source acquires critical geopolitical importance. It is no accident that the Brazilian interest in this area has intensified after Beijing’s decision to restrict export. The dilemma of sovereignty. And here lies the big problem. The Brazilian government He has shown A clear intention to claim the Rio Grande Rise as part of its continental platform, based on the argument that training He was united to the continent in the past. However, the highlands is 652 nautical miles from the coast, very outside the limit of The 200 established by the United Nations Convention on the Law of the Sea to delimit exclusive economic zones. This raises a challenge legal and diplomatic Complex, in which Brazil will seek to strengthen its exploration rights without violating international agreements. At the same time, warnings arise on the impact that an eventual mining exploitation could have little studied in depth ecosystems. Thus, the tension between the economic use of these resources and the need to preserve marine biodiversity appears as unresolved background dilemma. Global competition. In this way, the ancient island of Rio Grande Risetoday hidden under kilometers of water and centuries of geological oblivion, has reappeared as a Unexpected actor in the race for the strategic resources of the 21st century. Fosilized red soils, formed under disappeared tropical jungles, now lie next to metal scabs coveted by industries around the world. If you want, the finding not only highlights the scientific value of oceanic missions, it also exposes the growing global competition for those critical minerals in so many areas. In that new power map, where the control of raw materials marks the border between technological independence and structural dependence, even a sunk island millions of years ago can tip the balance of the future. Or at least that Think Brazil.

China has been so close to dying with its solar panels that has made the only logical decision: manufacture less

by

China is a colossus in the photovoltaic industry segment. They are not just installing huge parksbut dominate production with iron. So much that they have made The whole world depends on its technology and collapsed the price of the panels, drowning European and American manufacturers. The result of the crazy expansion was An internal price warbut after years of losses in the domestic market, they already propose a solution. Manufacture fewer panels. Storm. In 2020, China presented a zero emission plan Net for 2060. The goal is reduce your considerable carbon footprint and pollution and, for this, They marked That in 2030 there should be at least 1,200 GW of solar and wind capacity installed. The energy began to act, but companies from other sectors saw that there was a lucrative opportunity and got into the business. The result? Market saturation and such a beast production of the modules that were drowning foreign companies, but also to the domestic market. If 1,200 GW of renewables installed in 2030 were needed, only the solar installed in 2024 already surpassed The 880 GW. To the search for solutions. Production folded world demand And prices crashed, with huge companies in the sector asking the State for help To be able to continue in business. In that unsustainable situation for your own industry because They lost money with each salea kind of OPEC For Chinese photovoltaic, the Chinese photovoltaic industry association, or CPPO, with 33 of the main manufacturers signing a self -control commitment. The meeting was held in December last year and its executives are still looking for solutions after years of price wars. This week the Snec pv & is expo 2025 In Shanghai, in which manufacturers and companies around the world have met to evaluate the global situation. And, although we have to wait to see what measures they take, the Asian association of the photovoltaic industry – one of the organizers of the event – is clear that it cannot be followed in this situation. Or we refer to one or sink. As we read in South China Morning Post“The solar industry is not a zero -sum game,” said Zhu Gongshan, president of the association, in the inauguration speech. “We are in this together and the extreme cost of costs and fierce competition are not different from drinking poison to calm thirst,” he said. China installed About 278 GW of solar capacity last year, a figure that represents almost 60% of the new facilities worldwide. And it was the result of an overcapacity that contributed to a fall of 60% of the prices of the solar modules between 2020 and 2024. At the December meeting, one of the measures agreed by the main manufacturers was to respect a minimum recommended price to preserve the margins, and had a moderately positive result in early 2025, with a price rebound. But they don’t loosen the accelerator. The Cpia estimated Between 215 and 255 GW for this year, a cut in front of the amount of last year, but the accounts do not leave and the rhythm of facilities that are being kept is still very high: until April 30, 105 GW had been added, 75% more than what was installed in the same period of the previous year. It is estimated that it was because in January a large number of facilities were carried out and that they will fall 44% in the second half of 2025. One of the measures driven By the Government to reorganize the industry, it entered into force on June 1: sell production at market price instead of a guaranteed rate in the new solar plants. The antidote. “Instead of waiting for a cyclical recovery, we must face a disruptive restructuring in the sector,” said Zhu. And what are the proposals? Several are handled, such as focusing on improving collaboration between the government and companies to confront the offer through regulations or mergers. Another is that I know Bet on technological innovation for both panels and production chain, which will allow sustainable growth and higher benefit margins. That is, not to make the crazy panels that anchored to a technology that can be quickly outdated, but is cheap, but to improve quality and make fewer panels, maintaining a higher price and avoiding saturation. Change of mentality. Another problem is that there are too many things to consider. Those 33 Chinese companies of the CPPO are not the only ones that manufacture panels and there are those who may not respect self -control agreements. But, in addition, these internal problems are added tariff manids imposed by the United States. In the case of panels, Trump’s administration He imposed tariffs of More than 3,500% to the importation of panels from China and 60% to materials such as polisilicio, wafers and Chinese solar cells. China’s response, according to the president of one of the local businesses, should be internationalization. “Due to tariffs, it is no longer enough to export: we must locate production abroad,” said Gao Jifan, president of Trina Solar. We will see what happens, but try to stop that saturation of the market is significant, and that they talk about democrating production can generate a new battle from Western countries that we have already seen with the Chinese car: the one that try to attract the attention of manufacturers.

France is building a high security megacárcel for its most dangerous prisoners. 7,000 kilometers from France

by

In 2024, 110 people They died In France for reasons linked to drug trafficking and another 341 were injured in accidents or account adjustments. Although they are lower figures than those of 2023 —139 dead and 413 injured – in the Ministry of Interior they consider that they remain unacceptable. Your solution: attack the problem at the origin. 7,000 kilometers … and with a jail. The plan. Gérald Darmanin is the Minister of Justice of France and, a few weeks ago, advertisement The opening of 2028 of a new maximum security prison. As we say, curiously it will not be on European continental soil, but in the French Guiana on the other side of the Atlantic. In an interview, Darmanin commented That the goal of this third high security prison in France is to “leave out of the most dangerous drug trafficking profiles.” And, precisely, that those drug traffickers are at that distance from continental France will contribute to “take them away lasting their mafia networks.” Cocaine route. French Guiana is a overseas territory in France. Previously a colony -but abolished as such after the French revolution -, this French territory has established itself as a key platform for cocaine traffic from Brazil and Surinam Towards Europe. The figures scare: esteem that between 15% and 20% of the cocaine that enters France does it through the French Guayana-Paris route. It is done through “mules”, person (young and single mothers, especially) who are pushed by situations of extreme poverty to accept about 7,000 euros per successful trip to Europe carrying the merchandise. And the estimate It is that, on each flight from Cayena (the capital of the territory) to Paris, they travel between 20 and 30 mules, of which one third manages to pass without attracting attention. The jail. France’s goal is to build the new prison in the commune of Saint-Laurent-Du-Maroni. It will be about seven kilometers from the urban center and very close to the border with Surinam, one of the hot points of that cocaine route. The budget My dear It is about 450 million euros and the intention is that the complex, in addition to the prison itself, includes a court to expedite all judicial processes and procedures associated with inmates. It will have capacity for 500 inmates, of which 60 will be classified as “maximum security” and another 15 as “terrorists”, with a wing especially destined for those more dangerous inmates and will not only serve to fight drug trafficking, but to give a respite to the other prison of the French Guiana, a Rémon-Montjoly that has a capacity for 614 inmates and houses almost a thousand. And that inmates nickname “Dry guillotine“ Past ghosts. It may seem like a fissure plan to build a maximum security prison in the heart of drug trafficking towards your main territory, but far from it. The problem, or one of them, is all that it entails … and the historical precedent. Inspired by chow the British used AustraliaNapoleon III established a criminal system in the French Guiana that served as the main overseas criminal colony of the country from 1852 to 1953. In that century, especially the Salvation Islands and the Diablo Islandthey became the point where both common criminals and political prisoners shared space. They performed forced labor, severe punishments and there was a very high mortality rate: 75% in the blackest points. The few who could return to France told their stories in the place, making public opinion promote the gradual closure of the facilities that are currently Tourism focus. And fear. And how we read in BBCthe idea of ​​returning to the French Guiana that condition of ‘overseas prison‘He has outraged his population. A local deputy, Davy Rimane, considers that it is a unilateral decision by France, since they have not had the deputies of Guayana and that “transferring criminals from high level to Guayana, people who France do not want, return us to a terrible past, painful and full of suffering.” Because they are not only drug traffickers, but also Islamist terrorists who will be relocated to this prison. Rimane points out that they are not “the France dump.” Also in statements to BBC, the criminologist Marion Vannier of the University of Manchester considers that it is “a bad idea” to go from wanting one jail to relieve the other present in the country to devise a new system in which there are dangerous prisoners and high -level drug traffickers. “ As we say, the idea is that France has its new overseas prison from here to three years, but we will see if the plans are fulfilled because the Francaguayans do not seem happy with the idea of ​​returning to that dark past 70 years later.

In 2021 a volcano spent three days in eruption without anyone finding out. Now it helps us ahead of the silent volcanoes

by

Knowing how to read the signals that a volcano gives before erupting can make a difference between a scare and a tragedy. Some volcanoes make it easy for experts who know how to read these clues but others erupt without prior notice. Or maybe just we couldn’t decipher your signs. At least until now. A new tool. A team of researchers He has devised A new mechanism to model the behavior of some volcanoes. This tool, its creators stand out, will serve to more effectively monitor the eruptions of some volcanoes reducing the risk associated with these natural phenomena often so violent. Some special usefulness in the case of “silent” volcanoes. “Despite great advances in monitoring, some volcanoes erupt with minimally detectable or even without them precursors, significantly increasing the risk of nearby populations,” pointed in a press release Yuyu Li, co -author of the study. As explained by LI herself, some of these volcanoes are located not only near communities, also near important air traffic routes. Silent volcanoes. For the development of its tool, the team resorted to the Veniaminaf volcano, located in the North American state of Alaska. This is one of the so -called “silent” volcanoes, volcanoes whose eruption is not preceded by the signals that are generally associated with an imminent or close eruption, such as earthquakes or the deformation of the soil in the surroundings of the Magma Chamber. Veniaminof’s is just an example that We can find In this family of silent volcanoes that also includes some closer such as Stromboli in Italy or Popocatepetl in Mexico. Looking inside the volcano. But among all of them, the Veniaminof volcano is perhaps the most paradigmatic. Not because only two of the 13 rashes that have leaded since 1993 have been planned, but because in 2021 he achieved the milestone of erupting without anyone noticing Until three days later. The team responsible for the study analyzed the internal conditions that make it a silent volcano. Factors such as a slow supply of magma and a warm host rock are key in this regard. The monitoring of the volcano was carried out for three summers prior to one of the silent eruptions of the volcano, that of 2018. A model to get ahead of the eruption. The result, a model that conforms to the state of different variables that can condition the probability of the burst of the magma, such as the volume of the reserve, flow conditions of the magna, depth of the reserve or the form that it acquires is. Thus they could estimate what kind of conditions could be linked to a silent eruption and which ones were not. The team found that soil deformation could help prevent some eruptions of the volcano but that the relationship between underground magma and rashes were somewhat more complex than it might seem. The details of the study have been published In an article In the magazine Frontiers in Earth Science. The following steps. Monitoring the numerous silent volcanoes distributed throughout the world will not be an easy task. For now, the resolution gives a clue to what are the volcanoes to monitor more closely: volcanoes with small and warm reserves and slow magma flows, explains the team.
