memory

There’s a reason you forget to write things down on your shopping list: prospective memory.

by

Have I turned off the gas? Where have I left the keys? What was I coming to the kitchen to do? These are some of the questions we often ask ourselves. Of the three, the last one is perhaps the most interesting, the one that involves a form of memory with which we are not very familiar: the prospective memory. What exactly is prospective memory? This form of memory is what refers to our ability to remember planned or future actions, to remember intentions. It could be remembering what we were going to look for in the refrigerator or the dentist’s appointment on Thursday. Prospective memory is something we deal with in our daily lives, but it is not a concept that many people are familiar with. Neither do the experts: research on this form of memory was, until the beginning of this century, virtually nonexistent. But in recent years we have managed find out some key aspects of this memory. For example, we now have an idea of ​​which brain regions work for the correct functioning of future memory. A 2010 study found three regions of the brain whose activity was linked to prospective memory results: the parahippocampal gyrus, the left inferior parietal lobe, and the left anterior cingulate. However, there is still much to investigate in this regard. Other studies, for example, have given greater importance to the activation of the right lobe in relation to this memory. Othersfor example, emphasize the role of the anterior prefrontal cortex and the medial temporal lobe. But it’s not all neurobiology. Things we forget Why do we forget what it is that we were going to write down on the shopping list? Prospective memory is not very different in this from other forms of memory. Here attention is key. In one interview for RAC1 radiothe neuropsychologist Saul Martínez-Horta explained, starting from “what did I come to the kitchen to do”, he explains how it is that we have this facility to forget things. Distractions are one of the main factors that affect this memory. If we go to the kitchen to get salt, but in the meantime we remember that we left the oven on, this second fact will make us confused and make it more likely that we will forget about the salt. In Martínez-Horta’s own words “Normally what makes us forget what we should do is the saturation of the system and the distraction mediated by another event. brain capacity “It is limited and sensitive to distraction, so it is relatively easy for us to direct our attention to something other than what we are doing.” Concentration is, therefore, key if we want our prospective memory (or our memory in general) to have more of itself. Memory can be trained, but generally the exercises that allow us to do it They are not useful beyond of the memory function they seek to train. That is to say, there is no evidence that solving crossword puzzles will make us remember to buy popcorn for when we have visitors. That does not mean that we are helpless. Some healthy habits impact in our brain’s ability to perform its tasks, and although studies focused on prospective memory are scarce, it may be a good idea to incorporate them. A varied diet, exercise and sleep properly they can help us with our memory. Perhaps, they can also help us remember what it is that we were looking for in the closet before receiving WhatsApp from our brother-in-law. In Xataka | How much information can our brain store?

a river that stole their memory

by

In the north of the Iberian Peninsula the waters of a river flow that watered the nightmares of the Roman troops. And no, not because of its furious flow, nor because of its whirlpools, nor because of its length, nor because it is home to wild beasts or the habitual passage of fearsome warriors. What’s up? If the one known today as Limia River It was capable of stirring the dreams of the legionaries sent by Rome because of its legend. When they looked into its waters, the soldiers believed they were observing nothing more nor less than the dark depths of the Letheone of the rivers of the underworld of Hades. In a place in the north… The story of Limia is a story worthy of an epic start, on par with Don Quixote or the comics of that irreducible Gallic village they told us about. Uderzo and Goscinny. In itself it is not a particularly striking river: it originates in the province of Ourense, in the Mount Talariñoat a height of 985 meters, and extends 108 km until it flows into the Atlantic. Before that it runs through the south of Galicia and the north of Portugal, where it crosses the towns of Ponte da Barca, Ponte de Limia and Viana do Castelo. If it has gone down in history and remained linked to the Roman chronicle, it is however because of its symbolism, rather than because of its data. A river worthy of the underworld. It may be surprising in the 21st century, but in Roman times it was believed that the Limia was a unique river worthy of the underworld. And not just anyone. As remember the Ministry of Agriculture itself, a surprising legend was woven around its waters: it was believed that it was neither more nor less than the Letheor Lethe, one of the five rivers that flow through Hades. There it shared the land of the dead with other equally sinister channels, such as the Phlegethona channel of fire; or the rivers Acheron and Cocitoknown for their waters of affliction and lamentations. Among all of them, Lethe stood out for a fearsome peculiarity. It was considered to be the river of oblivion. Whoever drank from it suffered from total forgetfulness, losing their memories no matter how happy they were. Lethe passes through here. Whether the Roman legionaries believed more or less in the stories of their mythology and the magical power of the waters of the Limia, what can be intuited is that the legend was reasonably widespread at the time. This reflects it the thesaurus itself of the Cultural Heritage of Spain, which remembers that the Limia was known as Belión or Lethes, precisely because of “the confusion with the river of Oblivion mentioned in Hades.” This is what the Greek geographer actually calls it. Strabo. “It was believed that it made those who crossed it lose their memory, which made Roman conflicts in this environment difficult for years, since the military refused to cross it,” he adds. the token that the Ministry of Agriculture dedicates to him. Legend with expiration date. The legend of the Limia is not surprising only because of its background and popularity. Equally curious is that it can be associated with a very specific date, one that served to scare away the fears of the Roman soldiers. According to tradition, in 138 BC the general Tenth June Grossembarked on a campaign of conquest through the north of the peninsula, found that his troops refused to cross the Limia for fear of losing their memory. To show them that their fears were unfounded, the officer decided to set an example and leave a “similar” image—with all the quotes in the world, mind you—to the one he would offer centuries later. Fraga in Palomares: He went into the water to prove in his flesh that it was harmless. So, banner in hand, the good general crossed the Limia until he reached the other bank and then dedicated himself to calling his soldiers by name. One by one. First, to make your orders clear. Second, and no less important, to show incontestably that the waters of that northern stream had not erased his memory. A feat that is still remembered. Ironies of history, that feat with which Decimus Junius Brutus wanted to show that he preserved his good memory has managed to ensure that today, more than 2,000 years later, we are the ones who continue to remember him. About him and everything that surrounded the legend of Limia. For decades in Xinzo de Limia It is celebrated every summer “Festa do Esquecemento” (Feast of Oblivion, in Galician), a historical celebration with concerts, parades, market… and a recreation of the river crossing, with fighting on the banks of the Limia. Things about water… or wine. Beyond the festival, the truth is that the legend of Galician Lethe continues to arouse interest even today, in 2023, and articles continue to be frequently written that talk about the feat of June Brutus or the origin of the legend. The Debate published recently a report in which he collects the theories of Strabo or Virgil to explain why the Limia was associated with the Lethe, such as the supposed forgetfulness suffered by the Turdulian people when crossing its waters. Not all explanations were mythological, of course. The Roman poet even suggests that the explanation could well be a different one, more prosaic in nature: the abundance of wine in the region and its – yes – undeniable effect on memory.

When the Titan submarine exploded there was nothing left to rescue. Except one very important thing: a memory card

by

It has been more than two years since the Titan submarine tragedy and the story continues to make people talk. The last thing we know is that the recovery teams found the camera that was part of the submarine. The camera was damaged, but inside it housed a memory card from which they were able to extract image and video files, although none from the implosion. The discovery. Youtuber Scott Manley told it in your X account. In a series of posts, Manley has published several images of the camera’s recovery report detailing its characteristics and condition. It was a Rayfin Mk2 Benthic underwater cameracapable of submerging up to 6,000 meters deep thanks to its titanium body. Although the case appeared intact, the sapphire crystal lens was shattered. Upon disassembly, many of the components had light damage, but one of the boards included an SD card that was in good condition. The content of the card. Investigators and forensics managed to make a duplicate of the card and extract the contents. In total, they obtained nine images and twelve videos. However, the camera had been configured to save the captures on an external storage device, so it did not contain any images from the day of the fateful dive, but rather they were images taken at the Marine Institute in Newfoundland, which was where the missions to the Titanic departed. In the images they have shared you can see the facilities and some underwater images, but at shallow depths. Catastrophic implosion. The Titan left Newfoundland on June 16, 2023. An hour and 45 minutes had passed when communication was lost, but it was not until four days later that the coast guard found the first remains of the vehicle and confirmed what they suspected: it had imploded. They found remains of the vehicle, but no body of the five crew members could be found. It was avoidable. The Titanic is located at a depth of 3,800 meters, where the pressure is 380 atmospheres. There is vehicles capable of reaching this depth and even more, but the Titan had a long history of problems and his own Former director of operations called the tragedy avoidable. In fact, several members of the underwater exploration community, including James Cameron, They had written a letter to OceanGate where they expressed their concern and assured that they were “going down the path of catastrophe.” The company ceased its activity after the accident.

That WhatsApp devours my mobile memory is a thing of the past. These are the three habits I follow to avoid it

by

Running out of memory on our mobile is quite common and many times The culprit has a name: WhatsApp. With more than 3 billion usersis the undisputed queen of messaging apps. Everyone uses it, which means receiving hundreds of messages, photos, videos and audios through WhatsApp, making The size of the app increases exponentially over time. It’s happened to me too, but for years I’ve been able to keep it at bay by following these habits. Automatic download disabled If you haven’t done it already, it’s the first thing I recommend and you will only have to do it once (unless you change your mobile phone). The option is within WhatsApp in Settings – Storage and data – Automatic file download. By default, WhatsApp downloads all the photos they send us. For the rest of the files such as audio or videos, it only downloads them when we are connected to a WiFi network to save mobile data. The only ones that always download, whether you like it or not, are voice messages. If you want to control storage space, my advice is to change all options to ‘never’. This does not mean that you cannot see the photos they send you, you can do so but first you will have to download them. It’s adding one more step, but like this you can choose which ones you want to see and which ones you don’t. It is useful, for example, if you are in groups that send a lot of files, but you are not always interested in seeing them. WHATSAPP Tricks and tips to HIDE YOURSELF TO THE MAXIMUM and maintain your PRIVACY Delete multimedia content from time to time Even though automatic download is limited, I still download many of the photos and videos that my contacts send me, so the storage is increasing. Every so often I manually delete multimedia content that I have been receiving. WhatsApp has a very useful section to do this in Settings – Storage and data – Storage manager. I do two things here. The first is to access the section where the files that are larger than 5MBgenerally videos, and I delete those that I don’t want to keep. Here you will also see videos that you have sent yourself and that sometimes appear duplicates (this is because you have sent them to several different chats). When you have selected them, click on the trash icon (bottom right). The second thing is to go to the section ‘Storage details’, where you’ll see a list of all your chats ordered from the one that occupies the most size to the one that occupies the least. Entering one by one are all the files, also ordered from largest to smallest size, and I delete those that I am not interested in keeping. The storage you free up It will depend on how many files you are willing to delete. In my case, except for specific things, I don’t have much attachment to the content I share on WhatsApp and sometimes I delete everything at once. Review channels and groups that I no longer use Let them put us in WhatsApp groups for everything It is quite common. Personally, if I’m not interested or the group no longer makes sense (for example, if it was created for a specific event and has already expired), I leave and delete the entire chat. To leave a group you can do so from the chat list by holding down on it or, if you are in it, by clicking on the group name and choosing the ‘Leave Group’ option. You will see that two options appear, the one that interests us is ‘Exit and delete for me.’ Only then will the files and content that have been shared be deleted. With channels and communities I follow the same procedure. When it has stopped being useful to me for whatever reason, I quit. You can do this by entering the community you want to leave and clicking on the three dots icon in the upper right corner.

The bad thing about Framework Desktop is that it has welded memory. Good too

by

In 2021 the portable panorama was bleak in a key section: The right to repair. Manufacturers made it more difficult to try to solve problems or update these machines. It was then that a small and unknown company He showed us That there was an alternative. That company was called (and is called) Framework. Their Modular laptops have since demonstrated being An absolute reference in repability and expansion capacityand in recent years they have maintained that tradition. A few months ago they advanced the launch of Two new portable modelsbut next to them a surprising machine arrived: a desktop minipc that, curiously, seemed a betrayal to the principles of the company. That machine is none other than the Framework Desktopa different team both for its exterior and its interior. To start, we are talking about a minipc format equipment with a mini -it plaque and a tiny box with a volume of 4.5 liters. That box also has A differentiating design With a front panel in which we can place 21 “tiles” that we can also customize by printing them in 3D ourselves (The designs To do so they are available). The team also presumes from those already famous modular ports in their laptops and that allow to create a tailored inputs and outputs. We can buy them separately and incorporate new modules when we need it. That in regards to the outside. Inside, the technical specifications are as follows: Framework Desktop Processor AMD Ryzen AI Max 385 (8 cores, 16 threads, up to 5.0 GHz, soldier) AMD Ryzen AI Max+ 395 (16 cores, 32 threads, up to 5.1 GHz, soldier) GPU Radeon 8050s Graphics (32 nuclei, 2.8 GHz) Radeon 8060s Graphics (40 cores, 2.9 GHz) NPU Up to 50 tops Memory 32/64/128 GB LPDDR5X-8000 Welded Storage Flexatx 400W Front ports 2 x customizable I/O modules Rear ports 1 x HDMI 2.1 2 x Displayport 2.1 2 x USB-C (USB4) 1 x RJ45 (5GBE) 2 x USB-A (USB 3.2 GEN1) 1 x minijack 3.5 mm Feeding Flexatx 400W Dimensions and weight 96.8 x 205.5 x 226.1mm 3.1 kg 4.5 L mini -it box Price From 1,309 euros In these specifications it surprises how we say we find a configuration in which the AMD soc (with the CPU, the integrated GPU and the NPU) is welded to the motherboard, but it is also the memory. That seems a betrayal to the “replaceable and replaceable” spirit of Framework teams, and is something that has already caused some criticism. A the AI workstation for all audiences Some of the analysis Independents who have evaluated the team criticize him for that. However, that decision has its reason for being: as the company responsible explained in the Official announcement: “To enable the huge 256 GB/s memory bandwidth offered by Ryzen AI Max, the LPDDR5X has welded. We spent months working with AMD to explore ways to solve this, but finally we determine that it was not technically viable to install modular memory with high performance with the 256 -bit memory bus.” It is a reasonable argument, especially considering that although this team has a certain gaming personality, its true focus is another. These teams make use of a unified memory architecture (UMA) That makes no dedicated video memory: the GPU uses RAM as video memory, so 32, 64 or 128 GB of RAM are shared between CPU and GPU. It is an idea similar to the one handled by Apple in its MX chips: there the unified memory allows to be used interchangeably by the CPU or the GPU. And there is the interesting thing about these machines, which are in essence affordable work stations to work with local AI models. We already talked about this week of how GPT-Oss-20b, Openai’s open model was great but showed that having a lot of graphic memory was important for this type of scenarios. Well, Framework Desktop raises a decent alternative to Apple teams and their unified memory. If, for example, we buy the 128 GB model of RAM (2,359 euros), We could dedicate up to 112 GB of those available for video memory. That gives a lot of play to work with heavy models such as the “Large” variant of Openai (GPT-Oss-120b) or, as they explain in Framework, with models as it calls 3.3 70b Q6, for example. In fact, that is where this team really provides value, which also maintains a low profile in terms of power (the consumption peak is 140W) and also in noise. We are not before a gaming team competitor with dedicated graphics: if what you want is to play every pill (even in Minipc format), this may not be the best alternative. But if you want, you are rather occasional gamers and what you are interested in is to have a powerful work team and allow you to experiment with local AI models, We are facing what is probably one of the best current alternatives If you are looking for a compact, efficient and silent team. The other options are clear: a high -end MAC with the maximum amount of unified memory that you can pay, or a PC in which you combine several dedicated graphics (to add their graphic memories) and that therefore will consume a lot of energy, it will be voluminous and predictably make a lot of noise. Could Framework Desktop have been a more modular, reparable and replaceable equipment? Definitely. But that is what are already the majority of current PCs. Here the manufacturer has taken another way, and we believe it is a very interesting approach. Now it will be the users who will decide (you will decide).

Not for pleasure, but because the intestine has memory

by

A year ago, every time I ate something, my belly swelled like a balloon. I felt heavy, with gases, uncomfortable. I did not understand what happened to me, until I tested positive for bacterial overgrowth in the small intestine or its short version, Sibo. I started an antibiotic treatment and a very restrictive diet. I left gluten, dairy, nuts, fruits … almost everything. And when it seemed that I finally felt better, the strangest part of the process came: I had to reintroduce some foods, little by little, as if it were a vaccine; but I did, I would become intolerant. Increasingly widespread. Increasingly widespread. In both medical consultations and conversations, surely the term Sibo (for its acronym in English, bacterial intestinal overgrowth) is no longer unknown. This condition describes an imbalance in the intestinal microbiota: bacteria that should be found in the colon end proliferating in the small intestine, an environment where they should normally be almost non -existent. This invasion causes varied and annoying symptoms, such as abdominal swelling, gases, pain, diarrhea or constipation, According to Mayo Clinic. It is estimated that up to 15% of the Spanish population suffers from it, and is more frequent in women between 30 and 50 years, According to the Spanish Society of Primary Care Physicians (Semergen). Its diagnosis has increased in recent years thanks to greater awareness and evidence such as the breath test, a non -invasive technique that measures the amount of gases produced by bacteria after ingesting carbohydrates. After diagnosis. It is followed by a low diet in Fodmaps, a protocol that eliminates the most fermentable foods to relieve symptoms. It is not a cure in itself, but it helps reduce gas production and abdominal discomfort while antibiotic treatment takes effect. The problem comes later. We talk to Jesús Guardioladietitian-nutritionist, to understand what happens in that critical phase: food reintroduction. “A low diet in Fodmaps should not be maintained in time because, when restricting so much, it can affect nutritional diversity and microbiota. But also, if you stop consuming certain foods for a long time, you can lose tolerance to them,” he explains. The intestine also forgets. Stop eating gluten does not cause celiacy. This is an autoimmune disease that only appears in genetically predisposed people. However, eliminating it prolonged can generate an unexpected reaction: that the body tole it worse when reintroducing it, Guardiola points out. This can go through several mechanisms: enzymatic (the body stops producing enzymes such as lactase, necessary to digest lactose), immunological (less exposure can alter the immune response), or by changes in the microbiota (bacteria in charge of digesting that food disappear). From Monash Universityin Australia, an institution that developed the diet has explained about these effects in prolonged restrictions can reduce functional tolerance and affect microbial diversity. But not a real intolerance. No, of course. The point is that it has been shown that eliminating food groups can alter microbiota and digestive capacity. The body needs gradual exposure to adapt, so the reintroduction must be done carefully and individually, According to the academic institution. “The key is to do it little by little, evaluating the symptoms, writing amounts and reactions. If you introduce many foods at the same time and something feels bad, you will not know what it was. And if you do it too fast, it is more likely that you can fall or that you suggest you thinking that it will sit badly,” Guardiola warns. The diagnosis of Sibo. The boom has also been accompanied by some controversy. Each time it is diagnosed more frequently, but not always with clear criteria: in many cases it is by discard, when other pathologies have been eliminated, and sometimes without conclusive evidence. This complicates the precise identification of the disorder, and can lead to confuse with food intolerances, functional disorders or, simply, with bad habits. From Semergen They have insisted that the treatment requires a comprehensive approach: not only medications, but also changes in the diet, lifestyle and analysis of the full medical history. To this is added an increasingly common problem: patients who adopt low fodmap diets on their own, without professional supervision, and who keep them for months or even years. Instead of improving, this can end up deteriorating even more intestinal health. What I learned during the process. Today I eat gluten again. I am not celiac. But I went through months of fear of food, not knowing if what I ate was healing or getting sick. I understood that there are no good or bad foods, but contexts, quantities and, above all, processes. Reintroduction is not just another part of treatment. It is a way to reconcile with food. And to understand that, sometimes, the problem was not bread, but how we stopped eating it. Sometimes healing means exposing yourself to what you thought you hurt you. In my case, yes: I had to inoculate gluten.

Chinese memory chips manufacturers are a nightmare for the US and South Korea. There is a lot at play

by

Yangtze Memory Technologies Co. (YMTC) is one of the largest memory chips manufacturers in China. Its quota in the global market is approximately 6%so it is far from South Korean companies Samsung and SK Hynix, and also from the American Micron Technology, the three companies that lead this sector. Even so, Its weight in the Chinese market is very largeespecially because US sanctions They prevent American and South Korean memories manufacturers selling their most sophisticated integrated circuits to their Chinese clients. YMTC is in the spotlight of the US administration for more than two years. In fact, at the end of 2022 the Department of Commerce led by Gina Raimondo He decided to include this company in his blacklist because he had managed to develop an ambitious 128 layer memory chip. Currently YMTC is one of the companies that have the most advanced semiconductor manufacturing technology in China, and curiously, According to Techinsights He has reached this position without resorting to foreign technology. Not even Asml’s. YMTC aspires to intimidate the leaders of the memory chips market This achievement seems to have been possible because YMTC has the complicity of three of the most important Chinese lithography equipment: Naura Technology, Amec (Advanced Micro-Fabrication Equipment Inc. China) and Piotech Inc. The most shocking thing is that according to Techinsight analysts, which is a Canadian communication platform intimately linked to the semiconductor industry and with Great credibilityYMTC has managed to put avant -garde memory chips capable of rivaling the most advanced foreign solutions. YMTC has published about 20 new patents in which it describes processes that seek to increase efficiency And it has managed to refine its technology of stacking of memory cells in layers known as ‘xtacking’ until reaching a level of performance in its integrated nand type circuits similar to that of the comparable memories of Samsung or SK Hynix. However, this is not all. According to SCMPYMTC has recently published about 20 new patents in which it describes processes that seek to increase efficiency and optimize chips stacking structures. It is evident that the development of the technological capacity of Chinese manufacturers of integrated memory circuits represents a threat to Samsung, SK Hynix and Micron Technology. However, YMTC is not the only Chinese company with the ability to put in trouble the manufacturers of South Korean and American memory chips. Changxin Memory Technologies (CXMT) is one of the Chinese companies specialized in the production of memory chips, and, like other companies in the country led by Xi Jinping, it has chosen to compete in this market so attractive deploying a very aggressive pricing policy. CXMT in particular has increased its production capacity of DRAM chips almost five times during the last four years, which has allowed it to increase its global market share until it reaches a very worthy 9%. This growth has placed this company just behind Micron Technology if we stick to its market share, so it is already the fourth largest memory chips manufacturer on the planet. To curl the curl even more The Chinese government is supporting economically to its manufacturers of this type of semiconductors in response to the sanctions deployed by the US and its allies, so the competitiveness of Chinese companies is upwards.

We knew that smell and memory are closely related. And that unlocks an advantage: detect the Alzheimer’s

by

Alzheimer’s disease may be difficult to detect. The symptoms of this disorder usually become evident only after the progress of this dementia, which is a huge problem. And, in the absence of a definitive cure, our ability to stop the impact of the disease depends largely on early detection. Smell. One of the clues we have when detecting Alzheimer’s in its early stages is through smell. A study conducted by researchers from the University of Chicago analyzed the impact of the disease on our sensory capacity and detected that there is a rapid loss of smell when making us greater could predict with some accuracy The advent of Alzheimer’s disease. Smell of Magdalena. The relationship between memory and smell is very narrow. We know that the evocative capacity of smells It did not go unnoticedbut in recent decades science He has been confirmed This unique connection. The reason for this close relationship can be anatomical. The olfactory bulb is the region of the brain that processes in the first instance the smells and then send the signal to other areas of the brain. This signal crosses key areas of the limbic system, areas linked to emotions and memory. “The olfactory signals reach the limbic system very quickly,” Explain to The Harvard Gazette Venkatesh Murthy, head of the university’s cell and molecular biology department. 515 participants. The study of the University of Chicago had 515 participants, advanced adults, registered in the memory and aging project of the Rush University. These participants were examined annually, exams that test their cognitive abilities to detect signs of dementia. These tests also studied their ability to identify odors, in addition to other health -related parameters. More than memory loss. The team thus found a new link between smell and memory: a rapid loss of olfactory capacity prior to any cognitive loss could predict the arrival of various symptoms associated with Alzheimer’s. These symptoms included a lower volume of gray matter in the areas of the brain linked to smell and memory, cognitive loss and a greater risk of dementia. They also found a relationship between this olfactory loss and the presence of the APOE-E4 gene, a genetic variant considered risk factor in the advent of Alzheimer’s. The details of the study were published In an article In the magazine Alzheimers & Dementia. “This study provides another clue on how a rapid loss of the meaning of smell is a very good indicator of what will end structurally in specific regions of the brain,” ” explained in a press release Jayant M. Pinto, co -author of the study. Get ahead of the disease. Alzheimer’s is an incurable disease for now, but there are different treatments that allow us to delay the development of its symptoms. For that, we must get ahead of the disease as much as we can. Something difficult in a disorder that only shows its consequences once the disease is advanced. “If we could identify their 40, 50 or 60 people with greater risk, we could potentially have enough information to aim them in clinical trials and develop better medications,” also added in a press release Rachel Pacyna, work caoautora. Own initiative. The fact that the change in our smell is rapid and before the arrival of cognitive deterioration opens an important window, putting the patient itself in warning. And it is that most of the ways we have to detect the appearance of dementia is through external evaluations, for example when family members detect memory problems or In language. The loss of smell is something that, in principle, It can be striking to the patient himself and put it on guard or encourage him to seek medical advice. When the smell of the Magdalena stops bringing us memories, perhaps what we are playing is not only the evocation of a memory. In Xataka | We have a new “theory of all” to understand Alzheimer’s.

is leading the creation of a memory standard for the PCs with AI

by

Jensen Huang, the co -founder and general director of NVIDIA, is convinced that in the future most users will have a “supercommer of artificial intelligence (AI) Personal “. At the beginning of last January he led the presentation in the CES of Las Vegas (USA) of Project Digitsa very compact personal computer capable of executing models of up to 200,000 million parametersand therefore bigger than GPT-3. This computer is mainly intended for researchers, developers and students, although a good part of the latter can hardly invest the $ 3,000 (about 2,870 euros) that costs the most economical review of this machine. His heart is a soc GB10 that integrates a GPU with Blackwell architecture and a 20 -core CPU grace with ARM architecture. He works side by side with 128 GB of unified DDR5X type and low consumption type, although NVIDIA available memory standards do not seem to convince him for this scenario of use. Nvidia leads the development of the Socamm memory standard Projects Digits is just the spearhead. Presumably in the future NVIDIA will launch other personal computers even with greater capacities in The field of AIbut it seems that they will not use any of the memory technologies currently available. According to Sedailythe company headed by Jensen Huang has allied with South Korean companies Samsung and Sk Hynix, and also with the American Micron Technology, to develop a new memory standard known as Socamm (System on Chip Advanced Memory Module). Nvidia, Samsung, SK Hynix and Micron for the moment are not having Jedec These three companies are The biggest memory chips manufacturers of the planet, so there is no doubt that they are the best allies to which Nvidia can resort. Especially if the Socamm standard is being devised without Jedec’s participation (Joint Electron Device Engineering Council), which is the global organization that It is responsible for the development of standards used by the semiconductor industry and microelectronics. Apparently it is just what is happening: Nvidia, Samsung, SK Hynix and Micron for the moment are not having Jedec. In any case, what we know right now about Socamm memories, beyond the fact that they will be used in the next batch of personal computers for AI, paints very well. Although this information has not been officially confirmed by any of the companies involved in their development, it seems that the Socamm modules are being designed on the basis of LPCAMM memories (Low-Power Compression Attached Memory Modules). According to Sedaily, the Socamm standard will be very efficient from an energy point of view; It will have more I/O ports than conventional LPCAMM and DRAM memories (up to 694 ports); will allow to easily expand memory initially installed in the equipment for AI; And finally, these modules will have a physical size, which not storage capacity, much more restrained than conventional dram modules. If this standard contributes to the hardware for the most accessible to all, welcome. However, it is still early to trust that it will be so.
