How to predict the next epidemic? For researchers the solution is very simple: using AI

by

It arrives with heat, sneaks without invitation and leaves its trace on the skin: a red mark, an insistent itching, a sleepless night. The mosquito does not need a presentation; His buzz is part of summer. Now, we share our life with another invisible being: artificial intelligence. Silent, precise, without wings or sting, has begun to fight a battle with the old enemy. And in this story, only one can stay. The battle. A team of researchers from the University of Southern Florida, led by biologist Ryan Carney and computer engineer Sriram Chellappan, They have developed An intelligent surveillance system that uses artificial intelligence to identify, track and combat the most dangerous mosquito of the moment: Anopheles Stephensian urban vector of malaria that has already begun to expand in Africa. A unique method. The project key is to join advanced technology with citizen participation. On the one hand, they are developing intelligent traps equipped with artificial intelligence, capable of attracting, capturing and automatically identifying mosquitoes. On the other hand, the project relies on mosquitodashboard.orga global platform released in 2022 that collects photographs of mosquitoes sent by people from their mobile phones. Thanks to a visual recognition system, the panel identifies the species and generates in real time an interactive map that helps scientists follow the trail of the most dangerous vectors. And why? Chellappan team has developed unique algorithms capable of identifying a mosquito with only one photo, automatically recognizing its head, thorax, abdomen, wings and legs. This anatomical classification allows to distinguish species with great precision, even in challenging conditions. As He explained To Reuters, the advance in AI has allowed to identify where the diseases carrying diseases are because then the public health authorities can go there and launch control efforts to prevent new outbreaks. A global alert. Behind this technological deployment there is a real urgency, since mosquitoes such as the malaria transmitter are adapting and surviving in urban environments. However, there is a solution, because researchers have estimated for Reuters that smart traps could be manufactured for less than $ 150, which would facilitate their massive distribution as an early warning system in vulnerable regions. A war with many fronts. Although artificial intelligence promises to revolutionize the fight against mosquitoes, it is not enough by itself. “It will require more than one strategy,” He has warned Entomologist Tom Mascari in statements to Reuters. Technology is a key ally, but does not replace traditional measures such as the use of repellent. What is coming. In the next five years, the Carney and Chellappan team has planned to improve its algorithms, incorporate more species into the system and train a new generation of African scientists. The idea is that the fight against mosquito does not depend only on technology, but also on international knowledge and collaboration. And, perhaps, for the first time, the buzz of summer is not only a nuisance, but an opportunity to anticipate the enemy.

They are a simple way to save lives

by

Surely you have noticed them on a road trip, taking a walk through the field or in the vicinity of an airport. They are spheres of an intense orange or red that hang from the highest cables of high voltage lines. They might seem an inscrutable electrical piece, but reality is much simpler. They serve to save lives. Far from being an electrical component, these spheres have a simple function regulated by international aeronautical regulations. They have nothing to do with the management of electricity that circulates through the cables. His mission is to see. Signaling beacons. The technical name of these balls is spherical visual signaling beacons or beacon spheres, for friends. Its objective is to signal the presence of electric laying on aircraft pilots that fly at low altitude: helicopters, light airplanes, fumigation planes or emergency services, hot air balloons … In conditions of little visibility, with the light of dawn or sunset, or simply because of the thinness of the cables themselves, a high voltage line can become practically invisible against the bottom of the terrain or sky, which represents a risk of catastrophic collision. The spheres, with their bright colors and their considerable size, break the camouflage of the electric laying and alert the pilots of an obstacle that could be a deadly trap. They regulate civil aviation. Its installation is mandatory in areas of special risk according to the civil aviation regulations of each country, which in turn usually follows the guidelines of the International Civil Aviation Organization (ICAO). That is why they are usually quite standardized. They are in the vicinity of airports and helipuertos, crossing large valleys or rivers, in mountainous areas where aircraft can fly below the top and on large masses of water, such as lakes or reservoirs. They are not small. Its diameter is usually a minimum of 60 cm, although they can reach 90. They are made of light but extremely resistant to ultraviolet rays, such as reinforced polyester with glass fiberglass or high density polyethylene. Its weight is around 5 to 7 kilograms. The most common color is aviation orange, but white and red are also used, sometimes alternately, to maximize visibility in different light conditions and varied funds, such as a snowy field or a cloudy sky. The distance between spheres does not usually exceed 60 meters, although it can be reduced to 30 meters in critical areas such as the vicinity of a landing track. Secondary function. Although its main purpose is air security, these spheres fulfill a second ecological function: the protection of the avifauna. Bird collisions against electrical lines are one of the main causes of unnatural mortality for many species, especially for large and fast flights such as craps, stork or raptors. As for a pilot, for a bird in full migratory flight a thin cable is almost undetectable. Color beacons act as an element of visual deterrence that helps birds identify the obstacle and vary their course. In fact, in this field more specific devices have emerged already complementary, known as lifeguard or bird flight divers.

Psyllium went viral as a “natural alternative to Ozempic.” Reality is not so simple

by

Like any revolution, Ozempic came with promises and A hidden price. Then the side effects, the cost and the need for a medical prescription arrived. While its shadow is lengthened, an alternative option is born that does not need punctures through an millenary seed. The shell of a seed. What began as a traditional remedy in southern Asia today is a trend in Tiktok. More than 13,000 videos under the hashtag #psylliumhusk show how this fiber is incorporated recipes, Challenges and Tips for losing weightcalm appetite or improve digestion. But behind the viral phenomenon there is something much simpler: the Psyllium is the peel that surrounds the seeds of the ovata plantgo, a discreet but effective plant. Also known as Psilio, I know has used For years as soft laxative thanks to its ability to form mass and facilitate intestinal transit. The product can be consumed in dust, capsules or in its raw form, reminiscent of wood chips. Upon contact with water, this soluble fiber forms a thick gel. And it is precisely this viscosity that explains a good part of its benefits. Science behind. The secret of the Psyllium is how it reacts to water, since it absorbs and forms a thick gel. This process helps reduce appetite, improve intestinal transit and control cholesterol and blood sugar. In fact, an investigation He has confirmed ityou just have to consume between 10 and 15 grams daily to even reduce LDL cholesterol, the considered bad. Not everything is so simple. Although the enthusiasm in networks is understandable, experts ask for caution. First, for a security issue, since the Psyllium needs at least one liter of water for every 20 grams of fiber has pointed to The Guardian Lena Beal, spokesman for the Nutrition and Dietary Academy. The reason is none other than if it is not consumed without sufficient liquid, it can become a danger of suffocation or cause intestinal obstructions. It is not for everyone. It is not for everyone. Because it is natural, it does not mean that it is harmless. From Cleveland Clinic They do not recommend it in people with difficulties in swallowing, serious intestinal diseases (stenosis or crohn disease) or in cases of chronic digestive disorders. It is also advisable to take precautions if you are taking medication, since the fiber It can interfere. Natural Ozempic? Comparisons are always hateful, as the saying goes. The Psychlium shell does not alter the hormonal system as the GLP-1 agonists do. And although it can support weight loss, it does not do so in a powerful way or in all cases. More support. Because consuming more fiber is one of the most consistent recommendations of Modern nutritional science. In the end it is about incorporating improvements in the long -term diet, support that comes with a broader look on what it means to take care of yourself.

If the question is when the next blackout will occur, the answer is simple: it is impossible to know

by

He Bru what last April 28 It has generated many questions, and among them a couple stand out that seem inevitable: the first, if there are possibilities that it will produce again Another massive blackout. The second, if any, when will it happen? It is impossible to answer these questions with total certainty, although there are ways to reduce those possibilities to the minimum possible. Impossible to respond to that. To Niehls Bohr, the father of quantum physics, the phrase “making predictions is very difficult, especially when it comes to the future” is attributed. That also happens when trying to predict A nearby potentialsomething practically impossible and what also contribute several arguments. We still do not know the origin of the blackout. One of the problems of trying to answer that question is that we have no definitive or officers about what caused the blackout. From the Spanish Electric Electricity (REE) it was stated that the blackout It was due to a generation disconnectionbut they still do not give details about the specific causes that caused such disconnection. The experts They point to renewables As a possible cause, but at the moment nothing is confirmed. And without knowing the origin of the problem, we cannot know how to avoid it in the future. An unfortunate prediction. Pedro Sánchez, a jacket but without a tie, appears at a press conference. At a given time he says that “there will be no electricity blackouts.” The videowhich has now gone viral, it is not these days, but of September 6, 2022. At that time those words were pronounced in the context of a possible Russian gas cut throughout Europe. But there has been, and the question is whether there will be. The president of the Government was wrong in his prediction. Two and a half years later Spain has suffered The biggest blackout in its historyand one of the great questions that citizens have been asked is when the next blackout will occur, If it occurs. Never say ever. The research of the causes will lead to means for something like that not to happen again. The President of the Government spoke In your appearance of April 29 that there would be reforms so that “never” a generalized electric blackout is repeated like that of April 28, but even with all these reforms and measures zero probability does not exist. There are impodeables. Even in the case of detecting and correcting the problem caused by the blackout, it is still impossible to ensure that another will occur in the future. There are of course possibilities that a technical, human error or a natural catastrophe poses blackouts at some point. Spain has improvement margin. As we have commented In Xatakathe Spanish energy mix needs a stabilization system of the robust network, but also the Iberian Peninsula is an “Energy Island With very little international connection. Thus, we need an integration stronger With the rest of Europe to balance demand, strengthen system safety and share surpluses. There are other possible measures that can be taken, and as explained by the analyst Javier Blas In Bloomberg“The design of the network, policies and risk analysis are not yet up to the management of excess renewables.” All this is important when minimizing the risks of another future blackout.

Five very useful tech ideas (and simple to use) to give in the nail with Mother’s Day gift

by

May 4 is Mother’s Dayso you have to make purchases if we still don’t have a good gift. If this year you have decided to give you a technological product that is useful, but above all that it is simple to use, in this article I wanted to leave five interesting ideas that I have considered buying my own mother (some even I know that you want them for some time). Kobo Clara Color by 169 eurosa good electronic book reader who comes with color screen, ideal to read both books and magazines. iPhone SE (3rd Generation) by 339.15 eurosa simple, compact and front button mobile. Huawei Band 10 by 39 eurosa simple, discreet and good autonomy wearable. Hair dryer by 79 eurosa six brush in one of the most complete. Xiaomi Redmi Buds 6 Lite by 16 euroseconomic Bluetooth headphones, but also very useful and with a very good autonomy. Kobo Clara Color A couple of weeks ago my mother retired and one of the first things she set out to do is read more. He currently has an old ereader he had at home and that is going quite slow, so a much more current model can be a most interesting option. In my case, I would opt for the Kobo Clara Colorwhich has a price of 169 euros —In Amazon is cheaper, but the shipment takes several months), so that I can read both books and color magazines, although there is also the possibility of buying the previous model with black and white screen what costs 149 euros. He Kobo Clara Color It is an ideal ereader to read at home or to take it on a trip. It has a compact format with six -inch screen, so the letter is quite readable. Allows to enlarge the letter, change the sourceconfigure many pages parameters and includes an adjustable frontal light. In addition, you can transfer electronic books very easily, it has its own store and books can be given from many libraries (as is the case of Ebiblio) * Some price may have changed from the last review iPhone SE (3rd Generation) Over the years we have been seeing an evolution in the smartphones that have turned to “every screen” formats, thus eliminated the front buttons. Fortunately, some of them can still be purchased, as is the case with iPhone SE (3rd Generation)whose price in the mediumkt outlet on eBay is 339.15 euros. It is a mobile that comes from an exhibitor of the store and that is new and in excellent state. He iPhone SE (3rd Generation) It can be very useful for those older people who want a Mobile with a front buttonbut do not do without having a good touch screen. Apple’s mobile is also compact, something that is appreciated taking into account that There are less and less mobile below six inches. iPhone SE (3rd Generation) * Some price may have changed from the last review Huawei Band 10 My parents have some rivalry to see who makes more steps in one day. So far, they use their own mobile phones to measure them, but my mother has been around the head for a while making the leap to their first wearable. A simple, but also very useful model is the Huawei Band 10. In addition, it is also quite cheap, since it currently costs 39 euros (In Amazon it costs a few euros above its previous generation). He Huawei Band 10 It is a discreet activity bracelet that It has an elegant finish and a side button. It has all the basics to carry the bracelet on a day -to -day basis, it comes with an optical heart rate sensor and its battery offers a theoretical autonomy of approximately 14 days. * Some price may have changed from the last review Hair dryer I gave this month and a half Dryer brush To my partner and is delighted. He had been looking for it for a while to be similar to Dyson’s design, and the truth is that it is quite efficient. Costs 79 euros And it comes with many accessories to dry the hair, to curl it (it includes two accessories to curl hair in different ways) and also to smoot it. It is practical, it has an adjusted price and it is easy to use – the instructions are quite clear. Hair dryer 6 in 1 * Some price may have changed from the last review Xiaomi Redmi Buds 6 Lite Headphones can also be a good gift for Mother’s Day, especially if she likes to listen to music, listen to the radio or, why not, listen to some other podcast. There is much to choose from, but the Xiaomi Redmi Buds 6 Lite They have an excellent value for money. They can be found in Amazon by 16 euros. The Xiaomi Redmi Buds 6 lite are quite simple Bluetooth headphones. They are paired to the mobile or other device through Bluetooth connection and offer good theoretical autonomy – especially for the price they have. The headphones offer up to seven hours and the load case offers up to 38 hours. * Some price may have changed from the last review Some of the links of this article are affiliated and can report a benefit to Xataka.

How simple gestures tell us how good we are aging

by

In recent days, various media They have echoed of The statements what he did in his podcast Peter Attia, expert in longevity. In your program, The Peter Attia Drivethe toilet explained that a man between 40 and 50 years should be able to load his own weight (75% of his weight in the case of women) distributed between his two hands and walk for a minute. This raises a curious doubt: what does our grip force With longevity? Well, although it may seem surprising, our grip strength can tell us a lot about how we are aging. Several studies published in recent years seem to confirm this relationship, turning the grip force into an important biomarker linked to healthy aging. “People with better grip force age more slowly. Having a good grip force can slow down the immunosenescence process, or the deterioration of your immune defense associated with age,” Ardeshir Hashmi explainsdoctor at Cleveland Clinic. “You can also improve your ability to recover of diseases, or homeostenesis. Finally, it can prevent fragility. “ The lack of grip force is, for this expert, not only indicator of a faster aging, also a sign of a higher risk of chronic and even a lower life expectancy. Scientific literature seems to secondary this relationship. A study Published this year in the magazine Scientific ReportsIt is a good example of this. The study analyzed a population of 1,446 agent participants between 50 and 90 years of age, the majority (1,095) women. The team measured the grip force of each participant, who also filled a survey focused on estimate your quality of life. The team found a significant relationship between grip and the general evaluation of the level of quality of life. Another recent studypublished in 2023 in the magazine Journal of Cachexia, Sarcopenia and MuscleHe used biological watches to study the relationship between grip and aging force. Biological watches are different biomarkers that indicate to what extent or what rhythm our body ages beyond our standard chronological age. The study responsible for the study also found an inverse relationship between aging, measured through markers of the DNA methylationand the grip force. In other words: people with greater force of grip tend to age more slowly as observed in this study. Posted in the same magazine, but a year earlier, Another study He found that the little grip force was associated with a major risk of dementia Already greater mortality. This taking into account associated factors that could lead to establishing the relationship. These are some of the recent examples found in the literature. In 2019, A review of literature Published in the magazine Clinical interventions in aging He had already found, in previous analysis, evidence of the link between the grip force and health, through factors as varied as general strength, density of bone minerals, fractures, malnutrition, cognitive impediments, diabetes, depression or quality of life, among others. Remedying loss Some doctors, such as Dr. Hashmi recommend exercise to avoid the loss of this grip force, a loss associated with the age that tends to begin around the age of 50. According to hashmithis can be as simple as squeezing a ball (such as the classic antiestrés balls) for at least 10 minutes and twice a day. This without forgetting Conventional exercises that can help us to keep ourselves in form in more advanced ages. Although the recommendation to exercise and lead an active life is never more, it should be noted that the relationship between the grip force and our welfare and longevity is complex. Correlation does not always imply a direct cause ratio. For example, grip force can perfectly be correlated with our general health status. People who exercise will probably have greater grip force and also a better state of health. In addition, we know some forms of dementia and neurological diseases such as scleriosis not only reduce our quality of life, but also They affect our mobility and our ability to handle and develop when it comes to doing so.

bananas prices are in the clouds and the explanation is as simple as it is difficult to solve

by

At the beginning of the year, The Nightmare of the Canary Islands banana lasted 24 months. From January 2023 to October 2024, only in three months of the 22 the banana has had a “remunerative” price. The situation was terrible, almost unsustainable. And then, the penultimate week of February arrived. Since then, continuous increases in the price of the Canarian bananas have created a situation that we have not seen for a long time: up to four euros per kilo in the supermarket and 1.5, in origin. The banana is in the clouds. What is happening here? That is, how is it possible that the situation has changed so much in such a short time? And the answer, although it is the product of two different situations, is surprisingly simple. The first is the week cuttingl. As analysts recognize, on the islands, the weekly bananas cutting has been reduced. At the beginning of March (the latest estimates available), The figures were “Below eight million a week and even seven, which means much less embedded fruit.” That, by pure offer-demand, tends to raise prices. The second is banana scarcity. Because yes, the banana (the “banana dollar”) is the main competitor in the peninsular Spain of the Canarian banana. In fact, As Román Delgado explained in the Canary Islands now“Last year, half of the market share of this fruit in Spain has already been clear.” Well, the shortage of Canarian banana has coincided with banana shortage. The result is that, well, prices have shot. Above all, because the demand has remained. So Sergio Cáceres has recognized itManager and director of Marketing and Communication of the Association of Organizations of bananas producers of the Canary Islands (ASPROCAN), the organization that brings together 100% of the Canarian producers. And it is not uncommon: as we have learned with olive oil, The inelasticity of demand It is the main trick of national producers in times of crisis. So … the problem is already solved? The answer is also simple: no. Of none menra. To start because There are not two good months that can ‘cure’ the wounds caused for 24 bad months. Current prices are a good news, but teaching producers accounts requires some commercial stability. And not four euros per kilo. It doesn’t take so much. Just have remunerative prices for a prudential time. Secondly, for something that is closely related to this: the market is terribly volatile. The commercial chaos of recent weeks makes anyone really know what will happen to product flows worldwide. Who can assure that all bananas will not reach Europe in Europe that cannot be sold in the US (for tariffs)? Carpen Diem. Anyway, it would be fool not to celebrate that the islands have left their peculiar silver nightmare. It only remains to expect prices in the supermarket to begin to normalize and the increases do not erode the demand. In the coming years, we will have to make many decisions around the agricultural sector and the better we get to them, the better.

Green hydrogen consumes huge amounts of water. A new incredibly simple invention allows you to use seawater

by

Green hydrogen is the missing piece in the puzzle of decarbonization. In a day like today, in which Spain It has produced 107.3% of the country’s energy demand From renewable sources, a greater storage capacity (batteries or pumping centrals and a more flexible demand is needed. Produce green hydrogen When electricity is very cheap It is the country’s commitment to take advantage of that surplus. There is a problem. While green hydrogen It occurs with solar or wind energy (That is why it is said that it is an energy vector that stores clean energy), the process to produce itwater electrolysis consumes huge amounts of fresh water, an increasingly scarce resource for billions of people in threatened regions For chronic drought. The obvious solution is to use seawaterthe most abundant resource on the planet. But of course, salt and impurities run the equipment and reduce the efficiency of the process. External desalination makers are needed, adding costs and energy consumption; or super -resistant electrolyzers, which are still under development. There is a third way. MIT researchers, Cornell University, Johns Hopkins University and Michigan State University joined forces to find an alternative that nicknamed the “triumph of sustainability.” The system, detailed in Energy & Environmental Scienceproduces green hydrogen directly from sea water. It does so using solar energy with impressive efficiency, and generating drinking water as a byproduct. How they have done it. Taking advantage of the entire solar spectrum. The central idea of ​​this new approach, officially called HSD-We (Hybrid Solar Distillion-Water Electrolysis), is to squeeze the maximum solar energy. We know that photovoltaic panels convert only part of sunlight into electricity (The most efficient are around 25% efficiency). The rest of the energy dissipates as a residual heat. What if that heat, instead of wasted, will be used for something useful? Eureka! Simpler than it seems. Like many other systems for the production of green hydrogen, the HSD-We integrates solar panels that turn light into electricity and an electroly of protons exchange membrane (PEM) that breaks down the water molecules into hydrogen and oxygen. The secret is at the rear of the solar panels, they are where the HSD-We has an interfacial thermal distiller coupled that uses the residual heat of photovoltaic cells to evaporate seawater. A simple membrane that absorbs salt water. It is a genius. The best thing is that it works. The electricity of the solar panels directly feeds the electrolyz. At the same time, the residual heat of the panel heats sea water in the interfacial distiller, evaporating it. This pure water vapor (already without salt) is transported by a small air space to the electrolyz, where it is directly condensed in the anode, adding ultra -patrol water for electrolysis. The prototype, tested by the MIT both in laboratory conditions, under simulated sunlight, and outdoors, on a partially sunny day, threw impressive figures. They achieved 35.9 liters of dry hydrogen per square meter of solar panel per hour, using real sea water. In terms of efficiency, The system turned 12.6%a comparable rate or even above current green hydrogen production technologies with drinking water. Cheap hydrogen finally? Beyond technical feat, preliminary economic analysis is also promising. Not depending on external supplies of electricity or purified water, the operating cost is minimal, so the price of hydrogen produced with this system could drastically fall with the scale. While conventional electrolysis fueled by the electricity grid and using drinking water It costs about 10 per kilothis HSD-We system, in exchange for a slightly larger initial investment, could reach 5 dollars per kilo after 3 years of operation and lower the kilo at 1 dollar in 15 years. A price that would undoubtedly change the rules of the game. Image | Nickelgreen In Xataka | Europe waste so much renewable energy that needs green hydrogen. And the country that leads it is Spain
