We knew that living near the sea made us “gain” years of life. What we didn’t know is that it was literally

We have known for a long time that getting closer to nature has benefits for our health. Beyond avoiding pollution in our cities, getting closer to the natural environments around us can improve our psychological well-being, perhaps even encouraging us to lead a more active life. Little by little, we are also observing that something similar happens if we change the mountain for the sea. More sea, more life. A study has observed a correlation between residing in coastal areas and greater longevity. The analysis provide evidence of the link between bodies of water and the health and well-being of people. Of course, the relationship between “blue spaces” and health is a little more complex than it might seem. 50 kilometers. The study observed that the benefits of living near the ocean improved the quality of life of people residing within a strip of about 50 kilometers of the coast. Inland, however, they observed a very different trend: people who lived near bodies of water of a certain size (about 10 km² in surface area) tended to have shorter life expectancies. “Globally, coastal residents are expected to live a year or more longer than the median age of 79, and those who lived in more urban areas near inland rivers and lakes were more likely to die around age 78. Coastal residents likely lived longer due to a variety of interconnected factors,” highlighted in a press release Jianyong “Jamie” Wu, member of the team responsible for the study. 66,000 census areas. The study was carried out in the United States, where the team analyzed 66,263 census areas, studying life expectancy and its relationship not only with the proximity of bodies of water, but also with socioeconomic and demographic factors to control the results. Details of the study can be found in an article published in the magazine Environmental Research. Searching for the cause. The team points out different factors that could mediate this relationship, such as milder temperatures, better air quality, more opportunities for recreational activities, better transportation, less vulnerability to droughts, or income. These factors could explain why residing near the coast is associated with a longer life expectancy, in contrast to people who live near inland waters. “Pollution, poverty, lack of opportunities to be physically active and a greater risk of flooding are the main triggers for these differences,” Yanni Cao indicatedco-author of the study. Correlation or cause? Fits remember that the existence of a correlation does not always imply the existence of a direct (or even indirect) causal relationship. For example, if income is the determining factor, this causal relationship could take different forms. A possible route would start from the fact that the coastal areas they would be more expensiveso they would attract people with more income, income being a factor that we know affects our life expectancy. Another possible way would be that coastal areas generate higher incomes by offering more job opportunities, and these incomes would again be the determining factor in longevity. In both cases the mediating factor is the same, but the causal relationship is not.

Searching for extraterrestrial life has an unexpected new enemy: neighboring black holes

by

At the time of search for habitable exoplanetswe usually take into account factors such as whether they are within the habitable zone of their star or whether they have a sufficient amount of water. However, there is another parameter that has not been taken into account until now and that, according to a recently published study, may be decisive: the presence of supermassive black holes in the vicinity of the planet. Even distant black holes. This study, published in The Astrophysical Journalpoints to two types of winds generated by supermassive black holes. Some driven by moment and others driven by energy. The former are lighter, but the latter can be intense enough to leave a nearby exoplanet without an atmosphere. Since the atmosphere is indeed an essential ingredient for life, we should be paying much more attention to large black holes. In fact, if these winds are sufficiently energetic, an exoplanet could be affected even by a black hole located at a great distance. Much more than a living area. Generally, to search for habitable exoplanets, it is taken into account that they are within what is known as the habitable zone. This is a region that is at the right distance from its star so that it is neither too hot nor too cold and therefore the water can remain liquid. In recent years, much more specific factors have been taken into account, such as the proximity of supernovae. These stellar phenomena release so much radiation that it can sterilize life on a planet. They also emit shock waves so large that they can destroy their atmosphere. Since supernovae may be key, the authors of the recently published study also wanted to explore the role of black holes. What they found is very relevant to the future search for habitable planets. Active galactic nuclei. This study focuses on active galactic nuclei. That is, supermassive black holes, with masses billions of times greater than that of the Sun, that are actively feeding. That is, they continue absorbing matter into themselves. But, as is well known, black holes do not only absorb matter. There is also some radiation and particles that are released abruptly, giving rise to something known as jets. The movement of these particles also forms winds that can affect what happens around them. Based on the hypothesis that these scientists had, the more massive a black hole of this type is and the more it is feeding, the more energy it must release, so that the atmosphere of possible nearby exoplanets heats up more, its molecules move faster and escape more easily into space. Therefore, the atmosphere breaks down faster and its probability of habitability is lower. Unlike supernovae, which release energy much more abruptly, in this case it would be done in a sustained manner, so there may be more consequences. The two types of wind. Through the development of simplified models, it was observed that galactic nuclei release winds that, upon impact with the interstellar medium, divide into two streams. If they cool, they cannot expand, so they will have almost no energy. These do not propagate efficiently and have a limited effect on the galaxy. On the other hand, if these winds do not cool, they expand like a bubble, releasing a large amount of energy that can sweep the galaxy and affect the atmosphere of exoplanets along the way. These are the truly problematic ones, so it would be necessary to take into account whether there are any in the vicinity when choosing exoplanets that are candidates for hosting life. Also the ozone layer. It has been seen that these black holes can also release nitrogen oxides that affect the ozone layerin case a planet has it. If this is the case, it does not mean that there is not necessarily life, but it would be limited to the oceans. It would be another factor to take into account. With all these parameters, we can get a much more precise idea of ​​which planets could truly be habitable. Searching for life in the Universe seems to be like looking for a needle in a haystack. But the more we know, the smaller that haystack will become.

If you like the sound of it, we invite you to follow us on Instagram and, of course, to subscribe to Xataka Life on YouTube. We continue!

Astronomers have no doubt that there is extraterrestrial life. Mathematics says that it will take 1,500 years to find it

by

We have been sending signals to the cosmos for almost a century through high-power radio transmissions or even with military radars that exist around the entire planet. Little by little, humanity has been creating an electromagnetic “bubble” that expands at the speed of light, but unfortunately for some, we have not yet received a response to all these signals, and it is easy to fall into pessimism about the absence of other living beings beyond our atmosphere. The mathematics. The question here is not if we will connect with extraterrestrial intelligence, but when. And here the scientific community has great optimismsince the astronomical community is not based on UFO sightings, but on pure statistics. Here institutions like SETI They have been scanning the sky for decadesand although there is still no evidence of interference or signals of artificial origin, the conviction that we are not alone is stronger than ever. The bubble. To understand why scientists are so sure of this, you first have to look at the scale of the problem in our Milky Way, which is 100,000 light years across. This monstrous figure collides with our radio bubble that barely touches 100 light years, so on a galactic scale, we have not even crossed the street. This is where the famous Fermi paradox comes into play, which suggests that, if the universe is so vast and old, there should be someone around us, and that is why the question this researcher asked went down in history: where is everyone? The answer most supported by modern astrobiology is based on the “Mediocrity Principle”, an astronomical concept that maintains that there is nothing special about Earth and suggests that, if life arose here under certain physical and chemical conditions, it is statistically inevitable that it has arisen on a fraction of the billions of exoplanets that orbit habitable zones in our galaxy. Investigation continues. In 2016, an influential study from Cornell University put numbers to this paradox. To do this, the Drake equation was crossed with the expansion of our radio bubble with the aim of calculating how far our signal would have to travel to reach a sufficient number of stars to guarantee, by pure statistical probability, an answer. The result yielded a figure that has become a recurring reference in spatial dissemination: contact should not be expected before about 1,500 years. According to this mathematical model, for our signals to reach extraterrestrial ears requires that we cover at least half of the galaxy. Until then, it will seem like we are alone, even though the universe teems with life. Where do we look? While the 1,500-year clock continues to tick, scientists are not standing idly by, and that is why we have initiatives like SETI that they are not just looking to hear somethingbut to understand how we should listen to it. And for decades, the search for life has focused on very specific radio frequencies, highlighting the famous 1420 MHz hydrogen emission line, assuming that any advanced civilization would use that universal frequency to communicate. But… What if it’s not like that? New approaches aim to diversify the search towards broader technosignatures, since it is no longer just a matter of searching for an intentional “hello” in the form of a radio wave, but rather detecting electromagnetic pollution from other civilizations, the use of optical lasers for interplanetary communication, or even searching for signals at low-frequency radio frequencies that until now had been ignored or discarded by terrestrial interference.

We have been searching for extraterrestrial life for decades. According to these astrobiologists, we have been doing it wrong all this time

by

We are very used to hearing that someone has found possible signs of life in space. Then life is never found, but the trail seems to be there. All of these findings often end up being false positives, something astrobiologists are more than familiar with. However, According to a study just published in Nature Astronomy, They could be overlooking false negatives and that would be serious. Pass life long. What the authors of this study point out is that false negatives could be more common than we think. That is to say, many of the times when it is clearly concluded that there is no life in a place in space, it could be that it did exist, but it had been passed by without being detected. The causes. There could be three reasons why these false negatives occur. On the one hand, no traces of life are preserved. That is, it exists or has existed, but has not left a detectable trace. It could also be that this fingerprint is difficult to detect. Or, perhaps, that the methods used to detect it have limitations. Along these lines, the authors of the study give an example. Let’s imagine that there is a living being that, through its metabolic reactions, generates some gas that is understood as a trace of life. Maybe oxygen or methane. But let’s also imagine that there is a geological activity in that place that captures that gas from the environment. I wouldn’t have time to measure it. Therefore, the detection of life would have to be covered from other points. The risks. There are two main risks of not paying attention to false negatives. On the one hand, instruments that would help find even more traces of life would be deprioritized. If we do not find anything that justifies its development, we limit the possibilities of continuing searching. On the other hand, if life is not adequately searched for, resources from other planets where such life is found could be exploited. We would destroy it before we even knew it existed. Solutions. These scientists believe that searching for patterns using artificial intelligence could be an option. If the usual methods have not worked so far, perhaps we should ask an algorithm to detect patterns that have gone unnoticed to find new search paths. Along the same lines, it would also be necessary to study the terrain better and pay attention to anomalies. For example, if an unconventional type of oxidation is detected on a planet, inexplicable with what we know on Earth, it could be that it was associated with some form of life. It may not look like the oxidation carried out by terrestrial living beings, but who says it has to be the same? You have to think outside the box. Combine different types of work. In short, these scientists consider that to adequately search for life it is necessary to combine laboratory experiments with modeling and field work. But, above all, it is important to change the questions we ask ourselves. What if it has already been found? In 2019, a former NASA scientist told in an article for Scientific American that, according to himhis agency found life on Mars, but accidentally destroyed it. Supposedly, it all happened in the 1970s, in an experiment that was part of the Viking mission. This consisted of depositing nutrients in the soil and checking if gases typical of microbial decomposition were produced. Then, to ensure that it was not a coincidence, they would repeat the process, but adding a substance lethal to living organisms to the soil. In that case, gases should not be produced. And no, they were not produced, so there was something alive generating the gases. It was great news, but NASA did not publish that result, because when trying to replicate the experiment it came back negative. In science it is very important to replicate the results, so they concluded that it must have been a false positive. However, this former member of NASA, Gilbert V. Levin, believes that they destroyed life unintentionally and that is why they could not replicate it. This is no longer an anecdote. Most likely, they would not have found life. However, this story shows that we are always more predisposed to false positive than false negative. The focus would have to be changed a little. Maybe then we will finally find some life beyond our own planet.

NASA has looked at Torrevieja from space and has seen a huge mass of pink water essential to finding life on Mars

by

From space everything looks different. In fact, distance allows us to distinguish strange shapes, such as the Great Dam of Zimbabwe or the eye of the saharabut also colors that go more unnoticed at ground level. Thus, on June 7, 2021, an Expedition 65 astronaut aboard the International Space Station pointed his camera toward the southeast of Spain and took a photograph that looks like a watercolor: Mediterranean blue, a muted green and an intense pink reminiscent of quartz. The color palette is finished off by the white reflection of the sun. The three colors correspond to bodies of water a few kilometers from each other, in Alicante: the Mediterranean, and the saline lagoons of La Mata and Torrevieja. What seems like an aesthetic coincidence is actually chemistry visible from orbit. Each tone reveals something: the degree of salinity, which microorganisms dominate the water, and in what fragile balance they coexist. The lagoons of La Mata and Torrevieja. The Torrevieja lagoon has been used as a salt mine since the 13th century and today are the largest salt producer in Europe, with an average of 650,000 tons per year, a figure that varies depending on solar radiation, wind and precipitation. It does not function as a natural lagoon, but as an industrial system where water moves according to production needs. The La Mata lagoon acts as a prior concentration chamber: receive sea ​​water through artificial channels and runoff from intermittent streams of the Sierra de San Miguel de Salinas. From there, the water is pumped to the Torrevieja salt mine, where brine from the Pinoso salt diapir through a 55 kilometer pipeline. The result is that the concentration of salt in the Torrevieja lagoon can overcome 260 grams of salt per liter, much more than the 38.5 g/liter Mediterranean that bathes its coast. Two adjacent lagoons but with completely different chemical worlds. Why do they have such different colors?. Each time water of different composition is pumped to produce salt, the chemistry of the system is altered, which determines What organisms can live and in what quantity. Two lagoons a kilometer apart, two different microbial communities and two opposite colors. The pink color of the Torrevieja lagoon is produced by microorganisms. More specifically, in conditions of high salinity and intense solar radiation, the microalgae Dunaliella salina accumulates β-carotene as protection against light. The halophilic archaea that share the lake reinforce that tone: they have red pigments distributed throughout their cell membrane, which makes them visually more decisive in the final color of the water. In La Mata, the lower concentration of salt favors a different microbiota where chlorophyll predominates over carotenoids: that explains the green color. Context. The salinity gradient between both lagoons goes beyond chemistry: it is what allows a different and exceptional biodiversity. The wetland houses up to 400 taxaten species of threatened birds and one of the most important Audouin’s gull breeding colonies in the Mediterranean. Without that difference in salinity, many of those ecological niches would disappear. The NASA image is also more than a photograph: it portrays the fragile balance between industry, microbiology and conservation that climate change is already testing as temperatures rise and salinity fluctuations alter the living conditions of Dunaliella salinaor what is the same, that that striking pink color seen from space could disappear. Why is it important. Dunaliella salina is the organism that supports the base of the food chain in hypersaline lakes around the world. Since 1966 it has been grown commercially to produce β-carotene, which has applications in pharmacology and cosmetics. But it is also an organism that NASA has on the radar because it constitutes a form of life in extreme conditions. It should be remembered that the data from the Perseverance rover indicates that there were hypersaline waters in the Jezero crater of Mars. Studying life in these types of lakes helps understand the potential in these old Martian lakes. What makes Torrevieja pink is the best laboratory we have to know what to look for on another planet.

The mission is to teach them to work in real life

by

For a long time, the big conversation about artificial intelligence has revolved around models capable of summarizing, programming or generating images. But when we take that ambition to the physical world, everything changes. A robot does not learn to work just by reading instructions: it needs to observe, repeat, fail and accumulate data on real movements. That is why the next frontier of robotics is not only in manufacturing more agile bodies or more precise hands, but in building the entire system necessary to teach them to act outside the laboratory. This system is beginning to take shape in Fujian, where the province’s first large data collection factory has been launched in a test phase. According to CCTVthe facility is located in Area D of Fuzhou Software Park and has been created by Fujian Jufu Technology. There, almost 30 robots follow the instructions of different operators, described by Chinese sources as “teachers”, to practice tasks such as cleaning tables, sorting fruits and vegetables or disposing of parcel boxes. The mechanics of that “school” are relatively easy to imagine, but very demanding underneath. Operators wear virtual reality devices and operate controls to guide the robot during each exercise. When the operator raises his arm, the machine reproduces the gesture and, for example, grab a paper cup to place it on top of another. The important thing is not only that it completes the action, but that each movement, joint angle and clamp pressure is recorded by cameras and sensors. The school where robots learn with real data One of the least showy parts is also one of the most decisive. The tasks we see in the video, such as cleaning a table or picking up a glass, seem simple because we do them almost without thinking. For a humanoid, on the other hand, each gesture requires a specific sequence of physical decisions. Data collection engineer Jiao Shiwei explained to Fuzhou News that even the smallest movements need to be learned through data, and that each action must be designed according to the characteristics of the robot itself to find the most suitable trajectory. The key word here is “generalization.” That is, the ability to apply what has been learned when the environment is no longer identical to the training environment. Shiwei summed it up with two very basic actions: pick up a glass and clean a table. If the object, surface and stain do not change, the robot has it relatively easy. But in a house, a factory or a service space, almost nothing is repeated the same. Hence, data collection workers introduce variations in glasses, tablecloths and tables to expand the scope for learning. The bottom line is that robots are also entering their own race for data. In other areas of AI, much of the progress was based on digital material already available. In robotics, on the other hand, many of the examples must be generated from scratch, with real machines, real objects and movements repeated over and over again. Xinhua puts the problem in these terms: the bottleneck of humanoids is no longer concentrated only in the hardware, but in how to continue perfecting their “brain” through training in application scenarios. The industrial reading of the project helps to understand why these small tasks can end up becoming infrastructure. Chen Yishi, CEO of Jufu Technology, told Fuzhou News that these types of factories provide support for end-to-end models and implementation in vertical scenarios. The idea is that an AI robot does not function as a traditional machine limited to a fixed sequence, but as a guided system capable of make decisions on the body from real training. The company is also recent. Jufu Technology was founded in September 2025 and presents its activity as a combination of data factory and self-development. Its objective is not limited to accumulating examples of movement, but to create around that base a local ecosystem of algorithmic talent, data and collaboration with the industrial chain. Yishi, for his part, pointed out that its future products aim at industrial manufacturing, safety inspection, research and education, although sources present it as a roadmap, not as an already consolidated deployment.

Orange’s “life insurance” to protect the internet

by

More than 95% of international internet traffic travels over cables that are at the bottom of the sea. Africa and Europe start from very different positions, but they are essential to sustain essential services on both continents, such as the cloud or financial systems. Thus, while Africa It is the continent where demand grows the most bandwidth in the world and faces the problem of relatively old cables designed for much lower traffic than the current one, Europe has consolidated strategic nodes in places such as Marseille, Lisbon or the south of England, but is still exposed to the same risks of concentration and aging. Via Africa is born from both needs, the new submarine cable that Orange and an open consortium of seven operators have announced. The Via Africa cable. Via África is a new submarine fiber optic cable that will connect southern Europe with South Africa bordering the Atlantic. It will have European connection points in the United Kingdom, France, Portugal and the Canary Islands. On the western African coast, its nodes will be in Mauritania, Senegal, Guinea, Ivory Coast and Nigeria, although both the final complete route and other points in southern Africa are still pending definition. In any case, The reason for this cable is improve the diversity and resilience of international communications between both continents. Sketch of the layout. Orange Why is it important. To start with, this cable is the answer to that veteran and undersized infrastructure of the African continent and its growing demand at a time when cloud services, artificial intelligence and teleworking are skyrocketing traffic. Furthermore, the African Atlantic coast has some critical points due to the high concentration of marine infrastructure, such as the Ivory Coast, where several cables converge in the same physical place. This example is not coincidental: in March 2024 they failed the four cables that were there at that time at the same time due to a rockslide. The result? 13 West African countries with connectivity at minimum levels for weeks. But the problem is not only African: when these cables fail, Europe loses traffic capacity to the continent, dragging down operators, companies and cloud services that depend on that route. What Via Africa proposes is precisely a geographically different route, that is, an alternative that breaks that dependency. Six cables, the same physical point in the Ivory Coast. Submarine Cable Map Context. The African Atlantic coast is already served with cables such as SAT-3/WASC (2002), WACS (2012), ACE (2012), MainOne (2010) or Google’s Equiano (2023), but some of these systems are aging or have proven to be vulnerable. This new cable adds to a wave of investment in African submarine infrastructure, such as the recent 2Africa in Meta (2025) or the Medusa in the Mediterranean (2026). Orange needs few introductions: it manages more than 450,000 kilometers of submarine cables around the world through its subsidiary Orange Marine and in fact, last year charge two new cable carrier vessels to reinforce its maintenance and deployment capacity in the Atlantic, the Mediterranean and the Indian Ocean, with delivery scheduled in 2028 and 2029. How are they going to do it?. At the moment the only thing that there is closed It is a Memorandum of Understanding for its construction by a group of investors among which are CanalinkGUILAB, International Mauritania Telecom, Orange Group, Orange Côte d’Ivoire, Sonatel and Silverlinks. From here, the process starts with a route study to determine the optimal route in terms of resilience, technical feasibility and economic efficiency. Likewise, the business consortium will prepare the bidding process to select the cable manufacturer, the next step. Yes, but. The announcement is a memorandum with big names behind it, not a construction contract, which means that the stage of the operation is extremely early: it could take years until it is operational or even never materialize. In this sense, logically there are still important unknowns pending that range from the total layout and its length, all the nodes, the manufacturer and installer and the route sheet with a date for its entry into operation or the cost. Furthermore, Via África is going to enter a space that is not free: Google already operates Equiano on the same coastal strip and Meta has its own cable circumnavigating Africa with the very long 2Africa of 45,000 kilometers. In short, it will have to compete with the infrastructure of the large hyperscalers.

Researchers point out that the first 1,000 days in a person’s life are key to our life and memory

by

Something quite popular among society in general is that the youngest children are true sponges that absorb everything that is around them, this being fundamental for their adult personality. Here are some experts who specifically point out that the first 1,000 days of life are They are practically everythingsince a temporary window opens that can largely determine the intelligence, health and social skills of the future. But… is it like that? There are questions. Scientific evidence calls for pressing the brakes, since, although the overwhelming importance of these first stages of life is not denied, researchers are beginning to warn against absolute determinism. And all this because, although the first 1,000 days are a critical window, the next 1,000 days They are just as crucial. The first days. What happens up to two years in the brain, the truth is that it is fascinating, because here some research they point specifically because early feeding influences physical development and long-term metabolic health. But in addition, the attachment bond with an adult figure traces the physical, neural, cognitive and socio-emotional trajectories, meaning that, if this attachment does not exist, many problems can arise. But also, listening to caregivers, such as parents, speaking, singing and interacting, lays the foundations for the neural networks linked to language and the communication skills that we will have in the future. The effect on memory. We often think that memory is the adult ability to remember knowledge that we have ‘put’ in our brain ‘drawer’, but in childhood memory It is a basic neural learning mechanism and identity construction. In these cases, babies record constant sensory and emotional information, such as smells, voices, affective responses, and the receiving context. And precisely, experts point out that if at this stage the child is correctly stimulated and takes in the memories well, the brain “trains” its synaptic circuits, making learning new skills much easier in the future. It is literally as if a base is being generated (which we will not remember) to generate new skills in the future by generating very strong neural networks for future memory. We don’t have to be absolutists. Saying that only those 1,000 days determine cognitive and social development is a mistake, since the literature tells us that we are not facing a “closed window”, since human brain plasticity is amazing and does not have a switch that automatically turns off when two years have passed. From here, what surrounds the little ones in the house, the education they receive and also the social interactions continue to have a profound impact beyond 24 months. That is why simplifying the concept to the extreme can lead to a biological determinism that diverts attention from other equally important stages of childhood. Everything that happens. This is where the most recent evidence comes in so we have to focus on what they can be. the “next 1,000 days” which is the period that goes from 2 to 5 years. This preschool stage is not a maintenance period, but rather it is a new golden window of opportunity, since during these years complex motor skills are triggered when starting to walk, for example. But beyond this, language also goes from isolated words to a complex grammar and the ability to narrate and reason. And even social-emotional skills such as empathy or impulse control are also experiencing rapid growth. This is why promoting an environment of safe care and healthy habits in this period is capable of significantly altering and improving development, compensating for the deficits that may have occurred in the first years of life.

from useless grass to the birth of fascinating life

by

In 1995, several scientists who They studied ancient craters left by World War II bombs in Europe discovered something unexpected: Decades after the war, many of those holes filled with water had become small natural refuges where amphibians, insects and birds that barely found safe spaces elsewhere in the landscape thrived. A hole in the ground that ended up changing an ecosystem. In many gardens, the corners where water accumulates after rain are often seen as a problem: uncomfortable mud, grass that is impossible to maintain or small puddles that sooner or later someone ends up draining. However, in the midst of the global crisis that amphibians go throughthose spaces are beginning to look different. In fact, they had a few days ago in Economics a story that occurred on a small plot of land near a fish farm that demonstrates the extent to which something seemingly insignificant can be transformed into an unexpected refuge for wildlife. The idea of ​​building a pond that would disappear. Apparently, the owner decided to dig a shallow depression, barely about 60 centimetersright in an area where thaw and rain already accumulated water naturally before ending up being lost in a ditch. The key to the project was precisely that it was not a permanent pond. It was designed as a “vernal pool”a seasonal pond intended to fill during winter and spring and gradually dry out in summer. This detail is essential because it prevents the presence of fish, one of the greatest dangers for eggs and tadpoles. Shallow water also warms faster and accelerates the development of larvae before the pond disappears, something essential for species that live against the clock. The frogs are coming. The most surprising it was the speed with which nature responded. Just weeks after filling with rain and meltwater, five gelatinous masses of wood frog eggs appeared attached to submerged branches near the shore. Although at first glance they seemed like small isolated groups, each of these masses could contain hundreds or even thousands of eggs. The pond still had very little vegetation and just a few logs, leaves and accumulated mud, but that was enough for the amphibians to immediately identify the place as a safe breeding point. A corner of grass with no apparent use had just become a natural nursery for one of the most endangered species on the planet. The mud also attracted other species. The frogs weren’t the only ones to take advantage of the change. Part of the shore was deliberately left bare and muddy to favor swallows, which need wet mud to build and reinforce their nests. The previous year several had inspected the dwelling without remaining definitively, possibly due to lack of suitable materials nearby. Now the garden offered just what they needed. Plus: to that was added a bat box placed next to the pond, creating a small ecosystem where insects, amphibians, birds and mammals began to interact around the water. What was once a uniform surface of grass and pine trees began to transform into a much more vivid and diverse mosaic. The silent amphibian crisis. As they remembered in the middleall this occurs at a particularly delicate time for amphibians. Near of 40% of the species on the planet are threatened with extinction due to habitat loss, disease and climate change that alter the rains and dry out entire breeding areas. In this context, small temporary ponds like this one are beginning to acquire enormous importance because they offer just the conditions that many species need to survive. The problem is that, being small and seasonal spaces, there are often outside the protections traditional legal systems and go unnoticed in the face of much larger wetlands. The idea that is changing many gardens. He experimentFurthermore, it leaves a powerful conclusion: a simple shallow hole can become a useful piece within a much larger network of refuges for amphibians and other species. Obviously, a single pond will not change on its own the global crisis of biodiversity, but thousands of small interventions distributed among gardens, farms, parks or schools can begin to create safe corridors for increasingly pressured animals. And perhaps the most striking thing is that a good part of these spaces already exist: they are precisely those corners of the garden where every spring a puddle appears that someone usually tries to eliminate as soon as possible.
