For 120 years, scientists considered the Omiltemi rabbit extinct. Meanwhile, in Sierra Madre del Sur they were hunted for food.

by

When in 1904 Edward William Nelson identified the first Omiltemi rabbits, he did not know that this was going to be one of the last confirmed sightings of what, for decades, has been considered one of the most endangered mammals in the world. The bug. It was a large, nocturnal rabbit, with dark reddish hair, long ears and a short tail. But not much else was known because zoologists had frepeatedly scratched in finding and studying it. And yet, if they had asked the inhabitants of the Sierra Madre del Sur (in the Mexican state of Guerrero), they would have been able to add one more thing: that they are very rich. Because while scientists were looking for these bugs, neighbors hunted them and integrated them into their usual diet. Where are those rabbits? We must not fall into simplifications, since 1998 we already suspected that the rabbit was still alive and there. That year, some local hunters gave researchers the skin of a killed specimen: that is, we had physical proof that the species still existed. Therefore, the species was not officially extinct; What appeared in the species lists is that we did not have enough data to know what was happening with it. Now, after a long investigation with traps and sampling, we do have them. He wasn’t dead… Between 2019 and 2024, a team led by José Alberto Almazán-Catalán (the Institute for the Management and Conservation of Biodiversity) carried out a specific search for the rabbit under the program Search for Lost Species by Re:wild. They visited 10 areas and obtained records in 7 of them. The conclusion of this work (and I quote verbatim) is that the Omiltemi rabbit “is a rare species, but not only is it not extinct, but it is much more common than previously believed.” The data matches with the graphic material that Fernando Ruiz-Gutiérrez published in the Mexican Journal of Mastozoology. And then? Well, although the situation has not changed, it has revealed everything that we do not know. It is now evident that the distribution reaches an area up to three times larger than previously suspected. It is also true that, without suspecting it, the communities in the area have been hunting (and even breeding) these rabbits for decades without knowing that they were Omiltemi rabbits. And it is curious how this type of news helps make clear how little we know about the world around us. The initiative Search for Lost Species from Re:wild has already ‘recovered’ 13 species around the world. Some of them, like Winton’s golden molethey had gone 86 years without confirmed records. “There are more things in heaven and earth, Horatio, than your philosophy dreams of,” Hamlet tells Horatio and, if we apply it to contemporary science, we see that this is still the case.

Today on Netflix the series that, nine years after its premiere, remains the best thriller ever seen on streaming

by

How many times, watching a series, do you have that curious feeling of “I’m watching the history of the medium”? You may have noticed it with series that not only impact you in a special way, but you also know that the people around you who also watch it experience a very similar feeling. If you’re watching ‘Succession‘You’ll know what I’m talking about. My last time, before HBO’s magnificent family intrigue epic, was on ‘Mindhunter‘, that Netflix premiered in 2017. Nine years later, it is still my favorite series of all those released on the platform. Neither ‘Stranger Things‘, neither ‘The Witcher‘, neither ‘sandman‘ nor any other have managed to match the degree of intensity and perversity of this brief masterpiece by Joe Penhall (also screenwriter of ‘The Road’) in which David Fincher directed some chapters. It started from a real event in the history of criminology: in 1977, two FBI agents revolutionized investigation techniques, giving a twist to how to get into the minds of serial killers. The series is based on the book written by some of the protagonists, and although obviously the suspense and suspicions generated by the agents’ investigation are played here, as well as the portrait of famous murderers such as the Son of Sam, Ed Kemper, Charles Manson or BTK, the realistic reflection of an era is above all. A realism that takes great care to present heroes and villains, and much less to mythologize serial killers, as the worst do. true crimes. ‘Mindhunter’ describes with coldness and a certain perverse sense of humor (and here the Fincher style is clearly evident) these first times in which psychology entered in the darkest minds and abysmal, with a fascinating portrait of these first methodologies. And all supported by an excellent cast (Jonathan Groff, Holt McCallany and Anna Torv) that not only gives credibility to the ensemble, but also catapults the empathy we experience for a group of researchers who, literally, tread on absolutely unknown ground.

Evangelism has been leading a revolution in Madrid for years. Now he has turned the Metropolitan into a huge church

by

evangelism build muscle in Madrid. The weekend tens of thousands of people gathered at the Riyadh Air Metropolitan stadium to participate in The Change 2026a Christian event that had its first edition in August 2023 at the Benfica da Luz stadium (Lisbon) and revolves around gospel, prayer and evangelization. The event is important not only for its content or participants, which includes the footballer Daniel Alves. It is above all because it connects with other manifestations recent and multitudinous Christianity. What matters, but even more so when and where. What is The Change 2026? A Christian macro event held this weekend in Madrid. Its highlight came on Saturday, when a massive event was organized at the Riyadh Air Metropolitano stadium (Atletico’s field) which, according to organizers’ calculations, was attended by more than 35,000 people. In the website from The Change details that the first event of these characteristics took place in 2023, in Lisbon, and has already attracted thousands of people. At its genesis is the Rodrigues Pereira Association, an organization promoted by the preacher of the same name. Tickets to the event were freealthough they required prior registration and the organization accepted donations. Why is it important? Its attendance data is interesting in itself, but if there is a reason that explains the curiosity that The Change has aroused (and the comments that it has generated in networks) is that it connects with other much broader trends. The main one, the celebration of massive religious events in Madrid. We had the best example beginning of 2026when the city hosted two events almost simultaneously that had thousands of attendees. He January 10 Vistalegre served as the setting for a concert by Kahuna Group Music, a Catholic group that brought together thousands of people. On the same dates, the Movistar Arena hosted the prayer meeting Callswhich had Alpha España among its organizers and had the evangelical group Hillsong as the opening act. They were not two isolated cases. In April some 85,000 people They participated again in the fourth edition of the Festival of the Resurrection, organized by the Catholic Association of Propagandists and which once again featured Hakuna. Catholics and/or evangelists? It is not a minor issue. The Change vindicate that their event “is not the fruit of a single organization”, but “the heartbeat of a united church, with the same feeling.” The Catholic Church, however, has distanced itself from the event held this Saturday at the Metropolitan. In fact, on March 12, the Archdiocese of Madrid sent a statement brief and firm in which he made it clear that it had nothing to do with The Change. “This initiative is being promoted in our diocese by people outside it, in collaboration with a priest and an association led by a Portuguese evangelical pastor,” pointed out the Madrid Catholic Church, which clarified in passing that it was only informed of the event “when it had already been called.” “Consequently, the Archdiocese of Madrid does not consider itself linked to this event and regrets the call for activities of this nature in its jurisdiction without the necessary coordination with diocesan pastoral care.” Is it an important detail? Yes. Because it connects with a broader phenomenon that transcends the event held this weekend at the Metropolitano. Beyond the rise of Christianity (a trend that studies do not always support: some suggest a growing interest in the spiritual, rather than in orthodoxy), The Change or Llamados show a change in the way of expressing faith. A shift that also pivots towards a form of collective prayer and celebration centered on pop music, rock, big screens and collective prayers, manifestations far from the liturgy of more traditional Catholicism. Is it something new? No. The change comes from years back and it has not been without debate. The Online School of Apologetics has published, for example a list of “twelve reasons why it is not good to listen to Protestant music” and in 2011 the website Religion in Freedom he was wondering Whether Catholics should take note of the evangelists’ use of music. All this, between the controversy by Hillsong. In recent days, voices uncomfortable with the Metropolitan event have also emerged. One of the clearest is Universitarios Católicos (almost 132,000 followers on X), which took advantage of the weekend event to remember the rise of evangelism in the Community of Madrid. “One of the consequences of mass immigration: the loss of our Catholic identity,” concludes. Religion in Freedom assures that, although on Saturday people linked to the Catholic Church or Charismatic Renewal of Madrid could be seen in the stadium, the vast majority of attendees were not linked to the Church of Rome. Specifically, the media estimates that if in the event held in 2023 in Lisbon Catholics represented 25% of the public, in the case of Madrid they were 10%. What was seen in The Change? The event revolved around gospel, corporate prayer and preaching. Among the participants, names stood out such as Rodrigues Pereira or Dani Alves, former footballer for FC Barcelona and the Brazilian national team sentenced to four and a half years in prison (sentence later revoked by the Superior Court of Justice) for a violation. From that same thing, from his experience in prison, Alves spoke before the thousands of people gathered at the Metropolitano. “I was in prison for 14 months, but there Christ set me free. I have lost everything, but by losing everything I found Jesus.” Is it just religion? No. It’s culture. And demographics. Events like Saturday’s may grab headlines, but they are rooted in a much more important… and silent reality: over the last few years, evangelism has been expanding throughout Madrid, coinciding with the increase in Latin American migration. The Observatory of Religious Pluralism in Spain recorded a few months ago 834 places dedicated to evangelical worship in the region, which made it the minority confession with the greatest presence, ahead of Muslims. The phenomenon, very visible in the polygons where new … Read more

Murcians and Castilian-La Mancha have been fighting for nothing for years. Whatever happens with the transfer, what we are really losing is time

by

Ultimately, this is the story of a deception. Since 2019, the Supreme Court has been saying exactly the same thing: the application of the European Water Framework Directive forces Spain to change the way it manages its transfers. And he hasn’t said it once, no: if we talk about the transfer of the Tagushe has said it, at least, six times. Despite this, the different administrations have been interpreting a political melodrama for years that has prevented the design of a system that minimizes the problems that the directive may create. And the result is that Murcians and Castilian-La Mancha They have been fighting for nothing for years. Fortunately or unfortunately, this race forward seems to end on May 5. What happens on May 5? If everything goes as planned, on May 5 the Supreme Court will decide the future of the Tajo-Segura Transfer and the Tajo Hydrological Plan 2022-2027. That day, the high court will decide what happens to the appeal of the Central Union of Irrigators of the Tajo-Segura Aqueductthe last major judicial process that remains open against the changes that the Government approved in 2025 to adapt to the regulations. It is, so to speak, the last legal bullet left for the irrigators of the eastern peninsula. And what can we expect? Bit. The president of the union himself, Lucas Jiménez, has publicly admitted ‘cold spirits’ and ‘without great expectations’, given the meaning of previous pronouncements. And at this point, the issue being debated is whether the new ecological flows (which, according to the University of Alicante, will entail an average loss of 105 hm³/year from 2027) come into force now or may be staggered. But, the unpopularity of the measure in large areas of the country has caused everything to be postponed. To the point that the National Court just admitted to processing Castilla-La Mancha’s appeal for the Ministry’s inaction in publishing the new rules: in fact, if Scrats’ appeal is overturned tomorrow, there will be no rules to apply the transfer. And then? The conflict will enter a new phase: given the eventual rejection and with the transfer cuts legally consolidated, all that remains is to discuss technical details and compensation measures. We must not forget that the Transfer supplies almost 150,000 hectares irrigation in Murcia, Alicante and Almería. This is water that is already de facto granted to irrigators and the State will have to compensate them. Although, of the 1,450 million euros that Moncloa committed to cushion the blow, it seems that only around 5% has been executed. The story that never ends. We have been fighting over water in Spain for decades and we have been unable to create a system that reorganizes the country (and adapts it to real water). Almost the opposite: for more than 30 years, it has never been like this. As explained in Datadista“since the deep drought of the 1990s, each dry period has served to implement emergency measures (…) or allow practices that were not eliminated when the rains returned, they were used to expand irrigation, increasing the problem of overexploitation and contamination of aquifers and the wetlands they feed.” And the bill for all that is what we are paying now.

That bug has been waiting for its moment in Spain for 60 years. And your time is now

by

In 1964, someone decided it was a good idea to release a handful of estrildas in Portugal. Before the end of the decade, this small opportunistic bird from sub-Saharan Africa had already settled in Extremadura and Andalusia. By the 80s, it had already reached the east of the peninsula. For 60 years, estrildas had remained in a discreet background. It had taken root, but they weren’t getting traction. However, that has begun to change: in the last 15 years, Valencian estrilds have multiplied by 10 and in Catalonia the population has tripled. AND, to the surprise of the expertsthe key to the boom has been two other invasive species. What has happened? In recent days, several media have begun to publish reports announcing that the African bird “has already arrived” in Spain. However, the common estrilda has been here for decades. What is new is not that: what is new is that in recent years the proliferation of uncultivated plots (one in five are) is becoming the perfect breeding ground for two other exotic species, the common reed and the Pampa duster. And those species make the perfect habitat for estrildas. Do they eat them? No no. That’s why I say it’s curious: the researchers they have realized that it is not that birds consume these plants. The plants provide shelter, roosting sites and perfect structures for this species. The strilas have been surviving for years in a very hostile territory, now they have found some areas that suit them like a glove. The story, as you can see, is more complex. Above all, because it has an agricultural substrate. Without the profound changes of recent years in the countryside, neither the Pampa duster nor the common sugarcane would have reached where they have. In this sense, what is truly worrying is not the estrilda (a bird that, as far as we know, is not affecting the local fauna either). What has experts worried is the chain of invasions. You just have to think about it a little to understand: the feather duster is South American, the common reed is Asian, and the estrilda is African. Together, they have managed to become strong in southern Europe. Fauna and flora have logics that we are still unable to understand in depth. In the end, the key is always in the same place: that there is a moment when we are going to have to assume that the only way to get out of all the problems we are creating is to start comprehensively managing the field.

more than 2,000 years without hair and a sacred mission in the underworld

by

When I did the 1930s Mexican nationalism began to reclaim its pre-Hispanic past and rescue icons of the country. one in particular which stood out for its symbolism: the xoloitzcuintle. His name may not mean much to you, but you’ve probably seen him in photos or movies like ‘Coconut’by Pixar. He xoloas it is commonly known, is a dog breed originally from Mexico that stands out for two great reasons. First, because of his appearance, bald and athletic. Second, because of its history, which dates back to several millennia ago and connects with the Aztecs. For them the xoloitzcuintle was not just a pet, but a symbol associated with death and the last companion of the deceased on their journey to Mictlanthe Mexican underworld. A name that says it all. It seems like a tongue twister, but “xoloitzcuintle” is not only the name of a breed of dog native to Mexico. The word, from nahuatlthe language of the ancient Mexica, is in a way a description. There is who believes which is the combination of ‘Xolotl’the god of fire and death, and ‘itzcuintli’, which means dog. Others consider that the first part of the word is more of a nod to the hairless appearance of the animal, so it would be translated as “strange or wrinkled dog”. In either case, it is a fantastic business card for the ‘xolo’, a breed that has been linked to Mexico for millennia and stands out both for its exterior appearance and for its history and symbolic value. Hence, in the 1930s, the country’s nationalist movement “exalted her as a national symbol,” comment Raúl Valadez Azúa, from the Anthropological Research Institute (IIA) of the National Autonomous University of Mexico, UNAM. No hair or premolars. Its symbolic value may not be obvious, but as a breed the Xoloitzcuintle is unmistakable. Although there are examples of different sizes and varieties with and without hair, usually their specimens are distinguished by two characteristics: They are hairless and lack premolars. The reason must be sought in their genetic pool. During their first embryonic phase, three layers are formed in the xoloitzcuintle, like remember from the UMAN: the endoderm, mesoderm and ectoderm. The latter, however, is affected by a mutation that affects the teeth and fur. “It cannot be denied that a hairless dog is at a disadvantage. For example, when fighting with other dogs or in the face of climate changes. Despite this, after 2,000 years, it is still here,” reflect Valadez. Its peculiar condition also presents some advantages that have favored its bond with humans. Since it lacks hair, it is easy for us to feel its heat, which in the past caused xolos to be used with therapeutic purposes to relieve rheumatism or muscle pain. Just like huge hot water bottles. “A decision of the gods”. “The people of the region considered that, although the bald dog was a strange animal, its appearance responded to a decision of the gods and that therefore it was not up to them to kill it or decide its fate. Thus, they accepted it like the other dogs and called it xoloitzcuintle,” duck the UNAM expert. The result is fascinating: a characteristic that a priori could have represented a disadvantage compared to other races, ended up becoming a sign of identity that strengthened its symbolic value and the bond with men. An ancient race. If the appearance of the xolo is peculiar, its history is no less so. Experts believe the breed can date back to at least 2,000 years ago (there are those who place it even further back, to 3,500 years ago), emerged in western Mexico and after 500 years it began to disperse following two routes: one took it to South America, the other to Tula, Teotihuacán and Mayan territories. Its link with humans is also very old. Researchers have found remains dating back to 7th century and they seem to associate it, already at that time, with funerary contexts. They even suggest that he was attributed a role as guardian of sacred spaces. The Aztec dog. The remains of bones and ceramic fragments have allowed experts to better understand the role that dogs had in pre-Hispanic Mexico, where they were used for both eminently practical and symbolic purposes. Valadez remember For example, there are testimonies that speak of ritual sacrifices of hairless dogs in times of drought or during mass ceremonies, as well as others that reveal how their scavenging habits ended up associating them with death. “These animals were linked to the underworld because somehow what they ate in the underworld was converted into fecal matter, organic waste that was incorporated into the earth to pass to the underworld and, subsequently, returned to the earth as fertilizer that nourished the plants and, therefore, life,” reflect the expert However, if the xolo stands out for something, if something has earned it the nickname ‘Aztec dog’is the spiritual role that was attributed to it. The last companion. Its role in pre-Hispanic religiosity was so relevant that even today they highlight it the Mexican authorities, who have even designated the October 27 as ‘National Xoloitzcuintle Day’. Mythology claimed that when a person died, their essence undertook a journey to the underworld (Mictlán) that forced them, among other things, to cross the river Chiconahuapan. For that journey, however, he needed the help of the xolo, who would lend him a hand (or not) depending on how he would have behaved in life. Over the last few decades, researchers have found remains of dogs in graves, which has allowed them to confirm the belief that the deceased should be buried accompanied by a dog. Of course, with an important nuance: although at first it was believed that xolos were the favorite breed for that rite, the really relevant factor was the color of the coat. It had to be toasted. Other meanings were attributed to white or black hair that made them invalid for the journey to the afterlife. … Read more

a diamond from 2 billion years ago

by

It was at the beginning of the 20th century when, in a south africa minea foreman named Frederick Wells thought he saw a simple flash in a rock wall and decided to check it with his knife. What he got out of there turned out to be the biggest diamond never found, a piece so large that for years was doubted whether it was just a fragment of something even greater. The iconic scene left a curious idea that is repeated in the history of mining: sometimes, the most extraordinary finds appear just when no one is looking for them. Luck at the last minute. It happened at the beginning of April, when in one of the most remote regions of the planet, a few kilometers from the Arctic Circle, a mine which was already facing its last days of activity has left an unexpected discovery that rewrites its ending. This is not just a new geological discovery, but one that combines extreme rarity, almost unimaginable antiquity and a context that makes it something much more symbolic How usual. In a place on the planet where every extraction seemed to be part of the past, the earth has offered one of its oldest secrets at the last possible moment. An extraordinary diamond in every way. It is not trivial, because the stone found, with more than 158 caratsis among the largest yellow diamonds ever discovered in Canada, a country where this type of gem is already exceptional. In more than two decades of activity, only a few few comparable pieceswhich places the discovery in a practically unique and almost unusual category. The rarity is even greater when you consider that this type of diamond represents less than one percent of the mine’s total production. Two billion years. Yes, because the true value of this diamond lies not only in its size or color, but in its fascinating origin. The researchers said that, formed approximately two billion years deep within the Earth, it is the result of extremely slow geological processes that have remained intact until today. Its yellow color, a product of presence of nitrogen in its crystalline structure, it adds another layer of uniqueness to an already exceptional piece. On the brink of closure. As we said at the beginning, what makes this discovery especially significant is the moment in which it occurs. The Diavik mineoperational since 2003, just closed after more than twenty years of activity and more than 150 million carats extracted. In other words, this diamond appears as one of the last great discoveries before the end, functioning almost as a symbolic closure for an operation that has marking the industry in northern Canada. Extreme engineering in one of the harshest environments. The context in which the discovery occurs is key to understanding its importance. The mine operates in subarctic conditionswith extreme temperatures and in an isolated environment that has forced the development of advanced technical solutions, from containment dams in frozen waters to hybrid energy systems with renewables. This level of complexity turns each extraction into a logistical and human challenge that goes far beyond simple mining. Beyond the stone. During its lifespan, the mine has not only produced diamonds, but has transformed the economy of the region, generating thousands of jobs and important industrial activity. Furthermore, it has established collaborations with communities local indigenous people for the management of the territory and its future restoration, a key aspect now that the exploitation has come to an end and the environmental recovery process begins. The last gift. If you also want, together, the discovery sums up the essence of the entire operation: technology, nature and time converging in an unexpected moment. When everything pointed to a definitive closure without any major surprises, the mine has delivered one of its most extraordinary pieces at the last minute, as if the land itself refused to disappear without leaving a last trace. Thus, more than a simple discovery, the diamond has become the region in the final symbol of a cycle with the most filmy closing.

20 years ago someone believed they had the key to decongesting Madrid. Today it is gaining strength again with a name: M-70

by

In 2005, someone put on the table that, perhaps, the time has come to decongest Madrid from transit trips. That is, those that start outside Madrid and end outside Madrid. The idea is not new by any means. The M-30 or the M-40 They were born with the clear objective of keeping cars away from the city center. More kilometers for the driver but with the promise of taking much less time to reach our destination. The problem is that the municipalities and neighborhoods adjacent to the M-40 are enormous in Madrid. Some even merge with the city itself. As a result of this problem, the M-50. The highway finished being consolidated in the early 2000s. It has a total length of 85 kilometers and with it you can go from Las Rozas on the A-6 to San Sebastián de los Reyes, already on the A-1, surrounding Madrid on its southern side. It serves as a connection to the entire southern belt of the city, passing next to Móstoles, Leganés or Getafe but also next to Pozuelo, San Fernando de Henares or Barajas. The connection, however, is not closed in the north. That is, there is no direct connection A-1 and A-6 or vice versa, it is necessary to surround the entire southern framework because right now no highway crosses that space. The closest is the M-40 which, as we say, is next to the capital. But what if we go further? What if we try to eliminate traffic in Madrid with a radial highway that links all the provincial capitals that surround Madrid and without having to go through this autonomous community? This is what was proposed more than 20 years ago and now they want to recover. The M-70, an old Castilian desire Although it sounds utopian, the truth is that carrying out the Pentagon Project or the M-70, as the idea has been known since 2005, this idea has been raised more or less seriously. In fact, that year it was included in the Strategic Infrastructure Plan for Madrid just as they collected in 20Minutes and was considered of General Interest of the State as it was part of the Strategic Infrastructure and Transportation Plan (PEIT) 2008. The crisis, however, wiped out any reference to the project. That name of “Project Pentagon” It is because its construction would create a road network with this shape by joining Segovia, Ávila, Toledo and Guadalajara, passing through other municipalities of considerable size such as Ocaña, Maqueda or Tarancón. The name M-70 would not exist as such at the moment because, really, the objective would be to connect highways between said capitals in a kind of Frankenstein that would allow movement between all the radial roads near Madrid but without the need to enter said autonomous community. The last consistent reference to the project is a statement by Emiliano García-Page in 2024 who made reference to the fact that the connection of Cuenca with the A-5 through an extension of the A-40 would make the latter the M-70 of the city. And at the time of projecting that future M-70, it was already projected that the A-40 would be the road that would largely structure the project. This road, the A-40 It is a connection that aims to unite Ávila with Teruel. At the moment, on the west side, the road has been passable since 2012 between Maqueda (on the A-5) to Mocejón (past Toledo). At that point the highway is cut off as it passes through Aranjuez (the only point where it touches the Community of Madrid) and extends again from Ocaña to Cuenca. At the moment, that Madrid section and the connection from Maqueda to Ávila is in the study phase. And to finish this old dream of the Castiles, it would be necessary to extend the highway to Teruel from Cuenca, whose preliminary project has already been completed and approved. The concept of M-70, however, would be realized with the existing connection between Ávila and Segovia and, most complicated, the connection of the latter with Guadalajara. The “simplest” thing (yes, in many quotes) would be to create a connection between Segovia and the A-1 and reuse the latter in the direction of Madrid to unfold the possible ring road taking advantage of the route of the N-320. The latter connects the A-1 highway with Cuenca passing through Guadalajara. However, this Segovia-Guadalajara connection seems really complicated given the geographical accidents along the way. Despite this, as we said, a hypothetical M-70 ring road It would be an amalgamation of different highways or linked highways, not the construction of an entire ring road. It would, however, be a possibility to alleviate some traffic on the east-west and west-east routes without passing through Madrid. The A-40 wants to be that solution in the south but there were already those who dreamed 20 years ago of carrying it out also in the north.

The ocean fooled scientists with this “alien egg.” Almost three years later, we have the answer

by

Although we try to learn a lot of information about the space that surrounds us, the reality is that there is still a lot to know here on Earth. This is what we evidenced in August 2023 when the Seascape Alaska 5 expedition, at more than 3,200 meters deep in the Gulf of Alaska, found a shiny golden hemisphere and with a hole in the center. And the question was clear: how did he get there? Many questions. When these findings were seen live, the researchers themselves joked that it looked like the beginning of a horror movie, and social networks did not hesitate to dub it the “alien egg.” The problem here is that the scientific community had no idea what that artifact was doing attached to a rock on the seabed. But three years later this mystery has been solved. It’s not alien. After being extracted from the seabed, the enigmatic specimen was sent to the laboratories of the Smithsonian’s National Museum of Natural History, where a research team set to work to determine what it was. And to the disappointment of many, it is not a specimen that came from outside our planet. The results, published a few days agorelate how the researchers decided to extract and sequence the mitochondrial DNA from the tissue and, from this, they crossed it with the large databases of genomes that are already known and in this way they ruled out that it was not a marine sponge, a bacterial biofilm and it was not an egg either. What was it? Here the genetic code pointed directly to a species that was cataloged in 2006 as Relicanthus daphneae and of which, if we look for a photograph, we will be surprised to see a kind of giant anemone of the depths with tentacles that can measure more than two meters. And this makes us wonder: why did the Alaskan specimen look like a smooth, golden sphere? And here the research team points out that the golden orb found in the deep sea was not an animal itself, but a “cuticular relic.” What exactly is it? In other words, these are the remains of the base or “foot” that this anemone uses to anchor itself to the rocks of the seabed, resisting the strong abyssal currents. In this way, when the anemone dies, it detaches or moves; this fleshy and resistant base is left behind. And the hole? This was a point that greatly worried researchers in 2023, but the reality is that it was not the hatching mark of a creature, but rather it is simply a natural tear in this residual tissue. The curious thing here is that this find also fits with another similar specimen collected in 2021, confirming that this golden “mold” is a common trace of the species after its death.

Every time a child develops a asthmarhinitis or eczema, one of the questions we ask ourselves is why it happens, and one of the ‘culprits’ we point to is excess cleaning. Right now it is a reality that we live in environments that are too neat, using disinfectant gel all the time and not letting the little ones play in the mud because logically they can get stained. However, science here has ‘traveled’ to the past to find out the origin of allergies. What have they done? Here two new and massive studies based on the analysis of prehistoric DNA are putting the famous “hygiene hypothesis“And the paradigm we face now is that the evolutionary adaptations that our immune system has developed over the last 10,000 years to survive pandemics, curiously, are designed to protect you from allergies, not to cause them. A return to the past. To understand the plot twist, we must go back to 1989 where epidemiologist David Strachan proposed the hygiene hypothesis. Here it was proposed that the lack of exposure to microbes during childhood in most modern societies deregulated the immune system, since it literally did not grow with good training under its belt. In this way, it was proposed that, by not having real pathogens to fight against, the body created an imbalance that caused the immune system itself to attack substances that are not actually a threat, such as pollen or mites. And it seemed to make sense. A genetic journey. The first blow to this hypothesis has been dealt by a great published research in Nature this same month of April. Here the researchers analyzed almost 16,000 ancient genomes from individuals who lived thousands of years ago. What they discovered here is that the transition to agriculture in the Neolithic changed everything, since human societies became dense, we began to coexist closely with animals and, with this, large-scale infectious diseases arrived. But these pathogens that we began to face, despite the many deaths they generated, also favored hundreds of immune variants to ensure our own survival. But there is more. This is where parallel research that is revolutionizing our understanding of asthma and autoimmunity comes into play. Here is an article preprint has crossed ancient DNA with the modern complete genome with the aim of looking for differences between our DNA and that of our ancestors. Logic dictated that a system “revolutionized” by evolution to fight bacterial and viral infections of the past would be the cause of today’s allergies. But the data show exactly the opposite, as the study reveals that genetic variants that were positively selected in recent millennia have strengthened defenses in “barrier tissues” such as the intestine, against pathogens, but at the same time reduce allergic inflammation. The variants. Among these defense genes We have, for example, LYZ, which codes for lysozine, a fundamental antimicrobial enzyme in our secretions that destroys part of the bacteria. We also have FUT6, which is involved in protein fucosylation, a process vital to the interaction between our mucosal immune system and the gut microbiome. Why are we allergic, then? If our genetics have been evolving for 10,000 years to protect us from allergies in the lungs and intestines, the question is inevitable: why do cases continue to increase? Here science suggests that the problem is not simply an excess of cleaning in the present, but a profound imbalance. In this way, we do not need to catch diseases or live surrounded by human society, but the problem is that our immune system, genetically adapted to the strong pathogenic pressures of the first agricultural societies, expects to encounter a series of commensal microbes in the environment. The ‘problem’ is that these microbes are no longer present in modern cities and that is why the genes we have with a protective function cannot do their job correctly.
