What is High-Flyer, the Chinese fund that drives Deepseek and has been using AI for years to make investment decisions

by

Deepseek is the fashionable artificial intelligence (AI) company. Your most recent language models They have challenged Openai’s leadership and have caused a real earthquake in the technology industry. These days we have known that It was founded in May 2023 and that has developed its products with a fraction of the computing capacity of some of its main western rivals. But what else is known? Let’s see it. The promising present of Deepseek is the result of years of investigation that began long before its official constitution. Its origin is found in High-Flyer, a quantitative investment fund created in 2015 by the Electronic Engineering student Liang Wenfeng with two classmates. As they count on their websitethe idea was that the algorithms became the heart of their business by allowing real -time operations. A company focused on the Chinese stock market High-Flyer completed its first stock market assisted by AI in October 2016, a movement that triggered an unstoppable effort to continue working in that regard. The company formed software and hardware research and development teams. And apparently it was the appropriate decision. In 2017 I already applied AI In almost all its strategies of quantitative investment, but to continue advancing I needed to break some barriers. They discovered that complex models training tasks required a huge calculation power. This did not discourage them and in 2019 they launched a dedicated division called High-Flyer ai to address the challenge. The group built started working with 500 GPU, then built a 1,100 GPU supercomputer A100 of NVIDIA And in 2022 he spent 140 million dollars to raise the number up to 10,000 GPU, before the entry into force of the export controls of the United States. High-Flyer was completely focused on developing its algorithmic trading business. He had his own deep learning training platform and a Outstanding computer infrastructure. Meanwhile, in the United States there was a company called Openai that bet on the generative AI and that He had surprised many with the benefits of his GPT-3 language model. As China Talk collectsLiang wanted to go beyond finance. For a long time he had been convinced that AI would change the world, and had found the opportunity to bring his effort to the next level. In 2023, High-Flyer announced that it would lay the foundations of a new organization to advance the development of general artificial intelligence (AGI). Thus Deepseek was born, with an injection of capital of high-flyer. Deepseek is a product of High-Flyer work and has obviously drunk this company. Both signatures share offices in the same building, although they seem to use different computing resources. The AI ​​startup says it has H20 chips, that are sold as donuts in Chinaand NVIDIA H800, and that has used only 2,048 GPU of this latest model to train its most recent models, an affirmation that some have questioned.

They are almost 6,500 million light years

We are accustomed, or almost, to listen that the James Webb space telescope (JWST) has discovered a new galaxy in the confines of the observable universe. However, it is not always necessary to go so far to appreciate the immense power of the orbital telescope. Just stay halfway. 40 new stars. An astronomer team with representation of the University of the Basque Country and the DIPC (Donostia International Physics Center) has managed to capture in images and identify 44 new stars. This is the greatest number of stars identified in the distant universe to date. In addition to the stars, the team also discovered what could be a distant supernova. To almost 6,500 million light years. What makes this singular finding (in addition to the bulky number of stars found) is in the distance of these stars: these are found 6,500 million light yearsspecifically in the dragon arch galaxy. The stars find at such a distance that we see them as they were when the known universe had approximately half of their age. This galaxy is behind an immense cluster of galaxies, called Abell 370. A new lens for the JWST. The presence of Abell 370 It was instrumental in the discovery of these stars. All due to the gravitational lens effect. The enormous mass of these galaxies distorts the space around it, which diverts the light similar to how the lenses of a telescope do. This allows James Webb to see objects furthest than in principle would allow their already wide capacities. This phenomenon is also responsible for the “arched” aspect of the galaxy in which the newly discovered stars are located. The dragon arch is a spiral galaxy whose image comes to us as if it were a gum, all due to the influence of Abell’s cluster 370. The color of the stars. In his analysis of these stars, the team responsible for his discovery paid special attention to these. They discovered that it is red supergigants (such as the giant Betelgeuse, visible in the constellation of Orion). According to Explain the teamthis contrasts with previous similar findings that had predominantly detected blue supergigants. The details of the study were published In an article In the magazine Nature Astronomy. A new way to unravel dark matter. Beyond the relevance of finding such distant stars, the team highlights that the finding can teach us new details about the cosmos. Specifically, help us to reveal the mystery involved in dark matter.

Our rivers have been contaminated with medications for years. The EU has a solution: let the pharmaceutical companies pay

by

When we read that one of the great environmental challenges of our time is the state of our rivers, our imagination travels directly to the fecal waterindustrial pollution or, lately, microplastics. In what we don’t usually think It’s in the medications. But the problem is real and the European Union is determined to solve it. How can medications ‘contaminate’? Drugs (whether for medical or veterinary use) have a very long life after consumption. And, inevitably, a good part of the medications end up being expelled from the body and entering wastewater. From there, despite the efforts of treatment systems, they reach rivers, lakes and seas. An increasingly solid scientific consensus. Although it is difficult to get a complete idea of ​​the impact of this type of pollution on the environment, the investigations that are appearing They make it clear that it is very far from being an anecdote. In fact, at least 631 pharmaceutical substances (human or veterinary) have been found in more than 71 countries on five continents. Many of them, at levels higher than those considered safe. In 2022, the CSIC analyzed 258 rivers and, after cataloging the Manzanares River as “the most contaminated by drugs in Europe”, warned that we were in the face of “a global threat to the environment and human health.” “Global threat (…) to human health”? Are we not exaggerating? In the case of antibiotics, to use an example we are all familiar with, this is clearly seen. We have been warning for years that the abuse of these medications leads to the emergence of multiresistant bacteria. That’s true on the consumption part, yes; but also in the part in which enormous quantities of them are dumped into nature every year (with the problems that this causes for ecosystems and the risks that it poses). Why is this news now? Because the European Union wants to take action on the matter and, as Oriol Güell explainsis introducing a whole new battery of measures in the renewed Directive on Urban Wastewater Treatment. The goal is to “reduce the compounds discharged into the environment by more than 80%”; the environment, the introduction of a whole series of “quaternary treatments” (ozone, activated carbon, new membranes, etc…) in the treatment systems. The problem? that the EU wants them to pay the affected industries: above all, pharmaceuticals and cosmetics. An idea that the sector has not liked. As expected, the application of the “polluter pays” principle in these terms has not pleased the sectors involved. Above all, because of the costs. According to the employers’ associations of both sectors, the application of the European directive would lead to an increase of about 500 million euros in Spain alone. And, beyond the expected conflicts between companies and administration, it is true that the movement is paradoxical. Not because it is not reasonable to charge the costs of water treatment to those who produce them; but because just a couple of years ago, Europe announced its intention to bet on having drug factories on the continent (and thus reduce its dependence on international supply lines). Towards a culture of responsible drug use. Be that as it may, in the end we always return to the same thing: the drug industry is heading straight into a very complex crisis in which health, economic, environmental and cultural issues intermingle so as not to lead us to a dead end. One in which we risk our health, the future and our lives.

How wealth and land passed from mothers to daughters (and not to men) in Britain 2,000 years ago

by

Image source, BOURNEMOUTH UNIVERSITY photo caption, The investigation found several skeletons of women buried with valuable objects such as pots. Item information Author, Georgina Rannard Author’s title, Science reporter, BBC 1 hour 2,000 years ago women in Britain passed land and wealth to their daughters, not their sons, as communities were built around the female bloodline, according to new research. Skeletons unearthed in Dorset contain DNA evidence that Celtic men moved to live with their wives’ families and communities. Scientists found evidence of an entire community built around a family’s female bloodline over generations, probably originating from a woman. “This points to an Iron Age society in Britain in which women had a lot of influence and could shape its trajectory in many ways,” explains Dr. Lara Cassidy of Trinity College Dublin, Ireland, lead author of the investigation. Image source, BOURNEMOUTH UNIVERSITY photo caption, Archaeologists found well-preserved skeletons in the clay soil of Dorset. It is the first time in the history of ancient Europe that this evidence has been documented. of communities built around women. Scientists believe that the communities also invested heavily in their daughters, as they would likely inherit their mother’s status. “It’s relatively rare in modern societies, but it might not always have been that way,” Cassidy says. The team found evidence that this occurred in numerous places in Britain, suggesting that the practice was widespread. The communities analyzed lived around the same time as Boudica, the warrior queen who led a rebellion against Roman invaders in eastern England around AD 61. Dr. Cassidy sequenced DNA taken from the bones of 57 individuals from a tribe called Durotriges. People lived in Winterborne Kingston, Dorset, around 100 BC to 100 AD The skeletons were unearthed from a cemetery by a team of archaeologists from Bournemouth University, England. By tracking mitochondrial DNA, which is only passed between women, Cassidy discovered that most of the women in the community were related by blood ties that went back to previous generations. Instead, there was a lot of diversity in the Y chromosomes, which are passed from father to son, indicating that men from many different families married into the community. Image source, BOURNEMOUTH UNIVERSITY photo caption, The skeletons of people from the Durotriges tribe were very well preserved. DNA analysis also indicates that most of the ancestral line can be traced back to a single woman. The work shows that this society was what is known as matrilocal, meaning that a married man moved to live in his wife’s community. “The most obvious benefit for a woman is that if you don’t leave home, you don’t abandon your support network. Your parents, siblings, family members are still around you,” says Dr. Cassidy. “It is your husband who arrives, he is the stranger in the community and depends on your family for his livelihood and his land,” she adds. The researchers they found the same evidence of matrilocality in bones from other cemeteries, including those in Cornwall and Yorkshire. The researcher says evidence of powerful women in ancient communities has often been dismissed as isolated, not the norm, but these findings challenge that way of thinking. Archaeologists Miles Russell and Martin Smith found other evidence that women had high status. Image source, BOURNEMOUTH UNIVERSITY photo caption, The team from Trinity College and Bournemouth University excavated and analyzed skeletons of 57 people “We found tombs decorated with great care and with objects of great value. In each of the cases they were tombs of women, so we believe that wealth was transferred through the female line,” says Professor Martin Smith of Bournemouth University. The findings also support Roman writings of the time which suggested that women in Britain were quite powerful, more so than in Rome. But the Romans, like Julius Caesar, saw it as a sign of backwardness. “Women in Britain had power and it was a more egalitarian place. That was the biggest problem the Romans had with the British because Rome was a deeply patriarchal society. For them, it marked the British as the quintessential barbarians,” she says. Professor Miles Russell of Bournemouth University. Most societies today are patrilocal, meaning that women move to their husbands’ communities. But there are some matrilocal communities today or in the recent past, such as the Akan in Ghana, West Africa, and the Cherokee in North America. Scientists say Iron Age Britain may have been matrilocal because men were frequently outside fighting. Dr. Cassidy compares it to World War II, when women gained more political and economic power. Matrilocal societies are also less likely to experience internal conflict, he says. “They can promote feelings of unity between communities and neighboring towns. They disperse groups of related men, preventing them from developing strong loyalties and starting disputes with related men who live nearby,” suggests the researcher. The findings were published in the scientific journal Nature. Subscribe here to our new newsletter to receive a selection of our best content of the week every Friday.

Enriched milk: the best option for people over 65 years of age

by

Milk enriched with the milk fat globule membrane (MFGM) and foods that contain it can help people over 65 years of age to improve your cognitive abilities, including short-term memory. Reaching old age involves changes in the body that include neuronal wear and tear that has consequences such as diseases, memory loss, Alzheimer’s and senile dementia.A balanced diet, which, according to studies, includes foods rich in MFGM, can help recover the ability to remember recent experiences. Benefits of MFGM for cognitive health A study of the Department of Psychological Medicine at the University of Auckland in New Zealand reveals that The milk fat globule membrane (MFGM) contains “bioactive proteins, carbohydrates and lipids.”vital to improving mental health in three key stages of human life, that is, childhood, adulthood and old age. The study published by the specialized magazine Food indicates that MFGM compounds “play a fundamental role in maintaining the integrity of the cell membrane and the capacity for neuronal signaling, which promotes brain health.” MFGM and its phospholipid components can ““Improve mental health by reducing neuroinflammation and promoting the synthesis of neurotransmitters through the gut-brain axis.” Based on tests conducted by researchers on age-related cognitive decline, MFGM helps reduce the negative consequences of situational stress, improve brain health in old age, and reduce depressive symptoms. Other Oxford research reveals that sweet whey, the co-product of butter manufacturing, is rich in bioactive components of MFGM. How does MFGM help cognitive health? Fortified milk improves cognitive abilities in older adults.Credit: Shutterstock A study published by the “Food Sciences Research Institute (CIAL, CSIC-UAM)” found that MFGM-enriched milk improves episodic memory in people over 65 years of age and prevents mild cognitive impairmentquotes El Cronista. Milk with MFGM is rich in sphingolipids, ospholipids, and glycoproteins and other compounds that, as we already mentioned, are key to improving brain functions. These three components play important roles in brain health. For example, the main lipids in cell membranes are phospholipids, which contribute to strengthening the nervous system. While phosphatidylserine improves depression, stress and Alzheimer’s and sphingolipids promotes memory and brain health. Specialists recommend including this type of milk in the diet to prevent mental deterioration and improve the cognitive health of adults. Keep reading:

Bluray has been the last refuge of “physical” collectors for years. Now the industry is strangling it

by

Sony has announced that Abandon the production of physical formats Like Blu-ray. They are not the only ones: Panasonic, Sony and Oppo They stopped manufacturing playback devices in 2018, Samsung In 2019 and, at the end of last year, also did LG. We can be in favor or against physical formats, considering them more or less superfluous, but the position of the industry is clear: the players will increasing Games in physical format and the world of film disc edition, increasingly dedicated to collecting, disappears. It is not definitive, but almost. Although Sony’s pass is more radical, as we counted yesterday, LG has given some extra nuance to its decision to stop manufacturing players: it has eliminated the section of these devices from its website, According to Arstechnicabut from LG Korea they have not affirmed that this cessation is permanent. Although they are going to make a parenthesis in the manufacture and sale of their devices, of which he also did not take any new model since 2018, being the Ubk90 and Ubk80 The last ones that updated. Consoles are no longer the last redoubt. To this growing shortage of players is added that consoles are no longer that safe specio for physical format devotees. Both the Xbox Series X and S and PlayStation 5 took the market with Blu-ray player, but soon they joined Options without disk reader. But more than four years ago of that, and the trend begins to blow in the opposite direction: PlayStation 5 Pro leaves, by default, without disk (which can be bought independently at a completely deterrent price). And Microsoft’s turn towards a philosophy of “Any device is an Xbox“It favors the game in the cloud and the abandonment of the physical. Et tu, brute? Less records. Of course, accompanying this fall we have the descent of releases of the games themselves and, above all, films on the support. There are less and fewer stores that take care of it: the chain Best Buyone of the most important in the United States, has stopped selling Blu-rays and DVDs in 2024, and the extended Target He announced that he would only do so on indicated dates. In Spain, there is nothing more to take a walk through businesses that were once unavoidable appointment for the physical format collector: in El Corte Inglés, for example, the film zone has been reduced to the minimum expression, and serve on request in the most cases. The market is compressed. At a speed of infarction, in addition: between 2019 and 2023, the US DVD market and the Blu-ray 40% were reducedand the situation is complex enough to make it difficult to find a single guilty. The main and most striking is the streaming. Who sees movies to hang out finds more than satisfied their needs with the streamingdo not need to accumulate films in physical format that yes, they look better, but with nuances that only interest experts (we live times in which television come, by default, with Activated options that tasting the photography and color work of any movie). But Netflix and Prime Video are not the only villains of this story. It is the market, friend. The public that consumes physical format has also changed: before the arrival of the platforms, the economic formats such as the DVD and the latest VHS spoils made it economy to buy movies. Now it is a luxury article, on a parallel path to which they have followed The vinyl of music Let us add to this circumstance that the space for storing physical formats has been reduced in these times of rented rooms of 60 square meters, where every centimeter of bucket is vital, and we will have circumstances that are not favorable to the pile chaotic and compulsive of the DVDs: Do you remember when it was impossible to buy the newspaper without half dozen records?) Nor are the producers for the work. And finally, we have the companies themselves, little interested in the business of the physical, since the streaming It is much more profitable: a platform that includes its catalog or that of its partners in its offer bridges intermediaries such as stores, and gives more benefits. The digital format, in addition, means that if we want The same product, something that does not happen when a physical copy of a film is owned. We will always have collecting. Interestingly, while Majors They gradually distance from the physical market (Disney recently announced that he would edit less 4K movies, a witness that Sony would collect with part of his catalog, while the least commercial options of his cinema Possibly they would disappear), collecting and special editions live a golden age, on a new path very similar to the one traveled by the vinyl. Recoverations of classics, attention to unknown and worship as it was not seen from the first explosion of the VHS, and stamps as criterion, Arrow, 88 films, Eureka or indicator, among many others making some classical and modern cinema editions as not It had ever seen it. That is The authentic future of the format: A remnant for cinephiles and cinephagos.

Mobile phones have been stagnant for five years when it comes to innovation. There is an explanation

by

Mobile phones have not innovated for years. Or, at least, not too much. There was a time when jumping from one generation to another was a box of surprises. New designs, completely new features, and crazy innovations to surprise the public iteration after iteration. For a few years now, the meme of Smithers and the doll with the new hat has become more true than ever. The new phone will be the same as last year, with a little more power, a slightly better camera and AI features that we may never use. All this has a reason for being. The times of innovating are (almost) over. There was a time when manufacturers were not afraid to break the mold to create different devices. Samsung did it with the curved screen of the Galaxy Round, LG had a G Flex 2 self-healing, and Xiaomi dared with pop-up cameras from the body with the 9T Pro. There was a time when manufacturers dared to innovate. A few years ago, jumping from one generation to the next meant a significant leap. Going from a Galaxy S2 to an S4 was a brutal change. The same thing happened between LG G3 and the G5. It is true that the brands were taking some blind steps, completely changing the phone from one generation to another: there was not much consistency, but there were significant changes. Apple, which has always moved at its own pace, was one of the few that continued to maintain designs and advance specifications discreetly, without disruptive changes between generations. On Android, every year was an adventure. Being groundbreaking doesn’t work. The most innovative ones have not fared too well. LG ended up closing its mobile divisionNokia stopped inventing and started selling traditional, simple mobile phones under the HMD umbrella, and major manufacturers like Samsung, Xiaomi and Huawei began to make iterations that were increasingly similar to each other. No matter how many critical voices are heard against continuity, continuity works. Or so the data says. If we look at the list of best-selling devices in the world We found that, year after year, the iPhone and Galaxy (both mid-range and high-end) are the ones that repeat the podium year after year. Those phones that precisely “innovate” the least are the ones that sell the most. A path to refinement. The image you see above is a good example: it is even difficult to distinguish last year’s model from the new model. Manufacturers have changed the philosophy: if something works, don’t touch it. For approximately four years now, improvements between generations have been slight. Changes in the camera, small refinements in the design, updated processor, and some technologies such as WiFi, Bluetooth or USB that change protocols. The great innovations of these years have been camera buttons, longer telephoto lenses and the arrival of AI (which, no matter how much it is sold as a gimmick, plays a very secondary role in daily use). And it’s not a negative thing.. Smartphones are at a point of maximum maturity. So much so that it is difficult to think about how to improve them. Screens: we have as much resolution as practically that of a television. Very high peak brightnessand calibrations worthy of studio monitors. The big leaps will involve the implementation of matte screens and better drivers so that these panels are increasingly more efficient. Batteries: 2025 has been the key year for the implementation of carbon-silicon, bringing with it more capacity in a smaller size. 6,000 and 7,000mAh batteries are a realityguaranteeing two days of full use in many cases. There is still a way to go, but the great leap has already been made. Microprocessors: today mobile phones they are so powerful That, in many cases, this is a problem. We have not reached peak power, but we are at a point where a phone is capable of playing triple A games as if it were a console. Cameras: It is one of the points where there is the most room for improvement, but this does not happen through the hardware, but through the software. Formats: Manufacturers want to break with traditional formats, and that is why they are betting on form factors such as folding ones. These grow slowly, but they represent just 1% of total sales. Again, innovation does not sweep. We are far from the real peak. We have been thinking for years that we are approaching the peak smartphoneto that point of no return where it will be practically impossible to improve what we already have. We are right in our approach: progress is becoming less and less and, to appreciate it, it is necessary to be more and more thorough. Despite this, progress is present and, although they are minor changes, they are there. Your 2025 mobile has a processor that allows it to run the applications with the best performance. The quality of its microphones is getting better and better, its fast charging system is very far from those 2/3 hours necessary to charge your old phone and, in short, if we look back 3 or 4 years, the advances are still present, for small as they seem.

Leader of arms trafficking network between the US and the Caribbean is charged and could face 20 years in prison

by

United States Attorney Roger B. Handberg announced the indictment against Shem Wayne Alexander, 35, of Port of Spain, Trinidad and Tobago; and faces charges of conspiracy to commit illegal export smuggling and conspiracy to traffic firearms. Alexander was arrested in Jamaica on November 15, 2024, with a request for provisional arrest from the United States with a view to his extradition, which was fulfilled on December 20. According to authorities, Alexander was the leader of a group that illegally exported firearms, firearm components and related items from Florida to Trinidad and Tobago between 2019 and 2022. The firearms, including pistols and rifles, and related equipment were concealed within boxing and wrestling equipment, speakers and other household items to avoid detection by law enforcement and customs authorities. The criminal group led by Alexander also participated in phantom firearms purchases in Tampa by misrepresenting the identities of buyers and recipients. Even on April 7, 2021, Alexander ordered his associates to send a package containing several firearms from Miami to Trinidad and Tobago. This shipment included pistols such as the 9mm Taurus G2C and Ruger Security-9 models. Authorities intercepted these items at Piarco International Airport on April 22, 2021. The investigation was led by Homeland Security Investigations (HSI), along with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), with support from several agencies, including the Police Service’s Transnational Organized Crime Unit of Trinidad and Tobago. If convicted, he could be sentenced to a maximum of 20 years in federal prison. Keep reading:. Wisconsin woman found guilty of poisoning friend with eye drops.
