“We didn’t expect this.” A Ukrainian drone has revealed a Russian arsenal in a warehouse, and the surprise has been huge: the missiles are animals

From the early stages of the Russian invasion of Ukraine, when tanks were advancing while logistics columns were bogged down and fuel was scarce, the war began to reveal an uncomfortable paradox: the more modern it became in the skies, more “medieval” It was done on the ground. In fact, in that space where drones, satellites and trenches coexist, the return of solutions from the past apparently overcome was an early sign that the conflict was going to be, above all, a test of resistance. The latest Ukrainian discovery has confirmed that the wear and tear is tremendous. The return of the war of attrition. The irony is that the war in Ukraine has been shedding any illusion of modernity to return, as the days go by, to brutal logic of wear, one in which the quantity and capacity to take losses They weigh more than any technological “game changer”, and where the Russian army, pressured by the massive consumption of material and men, is beginning to show obvious signs of logistical exhaustion. On the southern and eastern front, the shortage of armored vehicles and modern systems is no longer hidden with silence, but is manifest in improvised solutions reminiscent of conflicts from another era and centuries, while Moscow insists on maintaining constant pressure on Ukrainian defenses at any cost. Cavalry in the 21st century. This wear and tear became visible at the beginning of 2026 when Ukrainian units detected and neutralized Russian assaults carried out on horseback, a tactic that seemed banished from modern warfare but that reappeared in sectors such as Oleskiivka in response to lack of means conventional. We are talking about small assault groups that advanced mounted, supported by prior reconnaissance, in infiltration attempts that ended up being aborted by drones and fire defensive, leaving such an absurd image (and repeated) as revealing: many horses survived, but the soldiers did not, and the Russian army confirmed that it was willing to resort to any available resources to sustain its offensive. The drone and the impossible arsenal. Now, the scene What finally condensed this drift came several weeks later, when a Ukrainian drone sneaked through the destroyed roof of a hidden warehouse, several kilometers from the line of contact, with the usual expectation of finding ammunition, fuel or military vehicles. What happened gives an idea of ​​these four years of slow war that has worn down both sides. Instead of artillery and technology to advance, the camera showed something that looked like something out of a rural garage: aging civilian cars, motorcycles from another era, and saddled horses, an “arsenal” as unexpected as it is eloquent of the state of the war in many areas. The message. “We didn’t expect to see this. It was really unusual,” said the drone pilot. to the Insider mediumspeaking on condition that he only be identified by his callsign “Cosmos.” “We were hoping to find some armored vehicles,” he added. He video It went viral because it summarized in seconds the real state of Russian logistics, but also because it demonstrated that those animals were not an isolated anecdote, but part of a system that already uses cheap and expendable media to move and attack under the constant threat of drones. Russia and the logic of sacrifice. For the Ukrainian commanders, this discovery is neither trivial nor a simple curiosity, but rather proof of a way of waging war based on accepting massive losses of material and personnel, replacing armored by civilian cars and horses because they are easier to replace. This logic, which prioritizes the attrition of the enemy, even if the cost is enormous, explains why Moscow continues to advance slowly, launching assaults with many times obsolete or improvised in regions such as Donbas, even when the monthly casualty figures, according to NATOreach levels that are difficult to sustain. If you will, the drone that expected to find missiles and found animals ended up portraying, better than any report, a war that moves backwards while consuming everything at hand.

dates, information and everything we expect from the games they are going to give away

As is customary on these dates, Epic Games is going to make its traditional advent calendar giving away games in your digital store. We are not going to know the games they are going to give away each day until the time comes to reveal them, nor the dates or the number of games, but we can get an idea taking into account what they did in previous years. Therefore, what we are going to do is tell you the first games already announced, and then we are going to take a look at what they have done in previous years to tell you what we expect this Christmas. These assumptions are the logical ones if nothing radically changes, but keep in mind that we won’t know until the time comes either. What are these Christmas offers? The Epic Games Store is one of the largest digital video game stores along with Steam. And every year around this time they usually make a kind of advent calendar, in which every day they give away a new game. To be precise, first they give away a bomb of game for a week, and then they start with the daily drip. Sometimes they can be important games, the so-called AAA, and other days they will be more independent or lesser-known games. But in any case, they will once again get us to enter their store every day to see the Christmas sales, and while you buy a free game, you may pay for another discounted one. Dates of the games that Epic Games gives away For now, Epic Games has only revealed the first of the games that he is going to give awaywhich will be available for a week. But the important thing is that it also sets a date for when to give the next one. This is important because, if they repeat the tactics of other yearsthe normal thing is that from that next game they start giving away one a day. Last year the daily games were extended until January 2, and then they put on another one for a whole week. These are the dates we know: December 12 at 2:00 (Spanish peninsular time) – Hogwarts Legacy December 18 at 5:00 p.m. (Spanish peninsular time) – New game From here on, the normal thing is that every day of the week give away a new game starting at 5:00 p.m. Spanish peninsular time. If Epic Games later specifies and confirms the gift schedule, we will update this article to tell you.

After reviewing the 50 most likely scenarios, this is what we can expect from Hurricane Gabrielle Camino de Europa

Hurricane Gabrielle advances through the central Atlantic at 16 kilometers per hour, feeding on warm waters, growing little by little, gaining speed. But none of that is especially important on this side of the ocean. It only matters one thing: that it is turning right in our direction. A changing scenario. Yesterday, the 50 most likely scenarios made it clear that the hurricane He was going to approach “To our region, with high probabilities of suffering an extroatropical transition (transformation on storm) of high intensity.” That is, a meteorologically very complicated event right off the coast of the Peninsula. In fact, like The meteorologist González Alemán pointed outThere were “scenarios where it would not suffer an extroatropical transition, but would approach without losing its tropical cyclone.” We had to pay attention to the Atlantic. Today those scenarios are converging progressively and everything seems to indicate that the worst part will take the Azores. And, with “worse part” I am not being metaphorical. “Some of the possible scenarios carry pressure centers even below 970 HPA”; that is to say, A very deep storm (and wild). The problem is that there are still six days left. And that, indeed, is a lot. To get an idea, according to the National Hurricane Center, it is most likely that Gabrielle loses his hurricane category between 12 and 24 hours before reaching the Portuguese archipelago. We already knew that Spain, like reminds us in Meteovigoit is difficult for him to llgue with the intensity of a hurricane because there are several “shields” that protect us (essentially deep water and polar jet). However, that does not mean that the impact of a storm of this type cannot be very intense. How of “intense”? That will be the question that we have alert for the rest of the week. If we have to listen to the current trend, it does not seem that the Peninsula will receive a direct impact. However, as I said, everything is very open. And in a season like this that is to say a lot. Because, although experts anticipated that the season was going to be relatively active, the truth is that the Atlantic Hurricanes factory has been surprisingly calm. Is there yet time to change this? Without a doubt, but there is less time left.

Farmers expect one of the worst harvest of what is going on the century

Pessimism is making its way in the grape sector. As the vintage season progresses in the different wine regions of our environment, the problems do not stop growing. The first was the price, with the farmers on a war for some prices that consider “ruinous”now, to this is added pessimism regarding the volume of the harvest. 34 million hectoliters. The 2025 harvest It is on its way to becoming In one of the worst views in recent years as the union of small farmers and livestock (UPA) recently stressed. Your concern is based on Estimates of the agro-food cooperative sector organization of Spain that indicate that this year’s wine production will be about 34 million hectoliters. As a contrast, The UPA points outan average season the wine production would be around 40-43 million hectoliters. From optimism to pessimism. The new estimate implies a remarkable cut with respect to the initial calculations, which trusted them to produce this year about 37.5 million hectoliters of wine and must. This fall is a reflection of an important change in the perception of what this harvest would be: of a optimism marked by the end of drought We have moved to a context in which pessimism predominates. Meteorology not so favorable. Meteorology has played an important role. The arrival of the rains seemed to bring new hopes to an agricultural sector punished by drought. However, hail storms, numerous this year, have taken its toll. He has also left his imprint in the harvest an extremely warm and drier summer than usual: the high temperatures of last month (in which we saw an intense heat wave) and the lack of rainfall have made a dent in the harvest, according to the UPA. More perhaps than meteorology, the sector also worries the climate: the UPA He also stood out The vulnerability of the sector to climate change, whose negative impact estimated at about 439,788 hectoliters, 1.4% of the harvest. The impact of the Mildiu. Another factor mentioned by the sector is that of Mildiu. This plants’ disease is a disease caused by fungi that infect plants and causes problems that end up being reflected in the productivity of the field. This Andalusia year, La Rioja, and Castilla y León have been the most affected communities according to the organization. A cGlobal RISIS. The volume of the harvest is just one of the problems that concern farmers. In its statement, the UPA also speaks of the uncertainty posed by the new US tariff policy, as well as the controversial reform of the common agricultural policy, the PAC. Although perhaps this year the great source of controversies has been economical. There have been several occasions in which farmers have protested because they consider that the prices offered by the wineries are not fair and that they focus on the crisis to their sector. To this we must add a structural problem in the sector, and that is that changes in consumption patterns have significantly punished the consumption of wine and many other alcoholic beverages.

The iPhone 17, closer than ever. Apple already has a date for your keynote and this is what we expect

The countdown has already begun. If you are thinking of changing your iPhone or you simply want to follow closely the latest news of the Cupertino company, there is a date that deserves to be on your calendar. Apple has just sent the invitations for your next Keynote. It will be the September 9 at 10:00 in the morning In Pacific Hora (19:00 Spanish peninsular time) and, as every year, it can be followed live through streaming. What to wait at the Apple event on September 9 Everything indicates that we will see the traditional renewal of the iPhone family. The great unknown is what the protagonist of this year will be. According to rumors and leaksthe focus would be put on the expected iPhone 17 Air. We are talking about a device that, as its name suggests, would aim to become One of the lightest and most thin market. It would arrive with a premium topped as usual in aluminum and glass. As we said, the device would not arrive alone, but accompanied by the rest of the company’s proposals. Among them is the presentation of the new iPhone 17, iPhone 17 Pro and iPhone 17 Max. Maybe the absence of the Plus model attracts attention. Everything points to what The iPhone 17 Air will take its placealthough with a different strategy that could serve to further boost sales. The autumn event could also bring news in the range of accessories of the US company, with special attention to new Apple Watch and a possible renewal of the AirPods. On the other hand, everything indicates that the day of the event will announce the Final versions of iOS 26iPados 26, Macos 26, Tvos 26 and Watchos 26.

The World Cup to the Comba exists, it is a hilarious thing and for us the question is obvious: what do the breath expect

Something that fascinates me is that we have the ability to turn anything into a game And, in turn, in a competition. If there is an Excel World Cupone of Collect garbage and Stone, paper, scissorsof course there is a world championship of jumping. It is a sport that needs great coordination and physical background, and a few days ago celebrated The World Rope World Blash championship in Japan in which the best on the planet have gathered. He is fighting so that the leap to the Comba becomes an Olympic sport, and I confess that seeing some video has managed to think that I am burning calories. Ijru. Are the acronym for International Jump Rope Union And it is the International Federation that organizes and regulates the competitive sport of the jump to the Comba. This is the highest world authority in this sport and is what seeks to expand the jump to the Comba as a high performance sport, promoting diversity, sports spirit, inclusion and those values ​​that make sports a universal language. The IJRU supervises affiliated organizations in more than 60 countries and something curious is that it was founded thanks to the fusion of two organisms that made the “war on their own.” On the one hand, was The International Rope Skipping Federation and on the other the World Jump Rope Federation and, with the aim of unifying rules and professionalizing discipline, reached good terms to become the current federation. Disciplines. Although it is not necessary to explain how it jumps, since it is a game that many have enjoyed at some point, perhaps you have to analyze what the disciplines are. Because in other sports such as football, tennis or Formula 1it is clear who already wins what is played, but with the comma it is different and there are several individual and collective tests: SPEED: His name says everything and consists of making the maximum number of jumps in a certain time that is usually 30 or 60 seconds or three minutes. Double Dutch: Two people turn two strings at the same time while other athletes perform the jumps. Triple under: You have to pass the rope three times under your feet in one jump. Freestyle: It is like synchronized dance, since athletes perform choreographies while jumping and tricks. It is tremendously complicated because not only the technique is judged, but creativity. Team routines: Similar to freestyle, where synchronized jumps, relay, acrobatics and any movement that involves teamwork are combined. Double combo. In addition, there are combinations such as Double Dutch Freestyle in which it is not about taking the maximum number of jumps in this discipline, but is combined with a free dance session. To qualify, athletes compete in national circuits sponsored by the Federation, and the best scores of each country are those that access places for the World Cup. The US, China, France or Japan are from the powers in this sport. 😮. Have you ever been watching a competition and exclaimed that “I’m tired just seeing them”? Well, beware of this video: That is the Double Dutch Speed, but in slow motion loses a lot of grace. Look at this at normal speed: It is not only about the coordination of the Saltadora, but about the rhythm and concentration that the two companions who are moving the ropes must have. But well, there is no easy category. Look at the ‘Single Rope Speed ​​Relay’ of this Chinese athlete in the competition a few weeks ago: These triples: The resistance session: Or this treesyle trees, which can also be played by teams Olympic objective. They are disciplines that would have a hole in some Olympics, but for the moment it is an honor that has not been granted to the jump to the Comba. However, the ijru is moving To be an accepted sport in the Olympic circuit, at least as a exhibition discipline. At the moment, the Olympic Games website itself has a reserved section For this competition, where we can see the finals of the World Cup in Japan held a few weeks ago, and On the Federation website We can see all kinds of rules about disciplines, the responsibility of athletes as behavior models or doping policies. The eSports have not yet achievedwe will see the jump to the rope that He slipped in the Olympic Games 2024 and that could follow the model of the Break Dance or Skate. Finally (because I’m still hallucinating with some jumps), I leave you on the last day of the World Junmp Rope Champioship by Kawasaki: Images | Ijru In Xataka | Millions of people are hooked right now to an Olympic Games where cats compete.

A millionaire spent a money to paint an exclusive RUF CTR YellowBird. I didn’t expect them to return it by doing the pine

Who plays with fire can burn, and who transports cars valued at millions of dollars also runs the risk of burning since the slightest carelessness can generate damage valued in thousands of dollars. This is what happened to a passionate owner of a RUF CTR ‘YellowBird’, one of the 80 more rare derivatives of Classic Porsche 911. After investing more than $ 150,000 in maintenance tasks and a total repainting of his painting, the valuable car It ended up rugged When downloading it from the truck that transported it before the stunned look of its owner. An icon of the 80s: the Ruf Ctr ‘YellowBird’ The RUF CTR ‘YellowBird’ is a modified version of the Porsche 911 Carrera 3.2 and developed by the German firm Ruf, specialized in converting the sports firm’s sports car In authentic beasts. Specifically, only 29 units of this RUF CTR ‘YellowBird’ were built, which makes it one of the most coveted cars in classic auctions, and a usual of cars video games. His exclusivity has led him to reach historical figures: in March 2024, one of these units was sold for 6.05 million dollars, As reported Topgear. Despite being based on the chassis of the Porsche 911, the Ruf Ctr It was very different In specifications. Its weight was reduced to 1,170 kg thanks to the use of aluminum in several body panels and carbon fiber defenses. It mounted a six -cylinder boxer engine with double KKK turbocharger, double intercooler and a DME injection system derived from the Porsche 962 competition. All of the above granted 476 hp of power and a maximum torque of 553 Nm, capable of exceeding 342 km/h in official tests, surpassing Ferrari F40 by then. Of “yellow bird” to bright black Be that as it may, the Ruf Ctr ‘YellowBird’ protagonist of this story is one of these 29 unique copies that originally went on the market with a body painted in a striking yellow color, as indicated by its last name ‘YellowBird’. Looking for a more elegant appearance, the owner resident in California sent his unit to the RUF headquarters in Germany so that, in addition to making mechanical adjustments, the car in bright black was repainted. For many collectors, modifying the original color of such an iconic model may seem risky, but in this case, the change added an even greater touch of distinction. As you can imagine, neither the transfer nor the restoration process was at all cheap. In total, the owner disbursed more than $ 150,000, according to details Road & Track. These types of restoration operations are common between collectors of high -value cars, which do not hesitate to send their vehicles even to other continents to ensure that they are in the hands of experts accredited by the manufacturer. A very expensive carelessness The tragedy arrived just when the owner was about to receive his Ruf Ctr back and with his new body color. When downloading it from the truck in the transport gondola, the car tires were not correctly secured, which caused it to slide through the ramp without control. Deportivo fell painfully from an approximate height of 2.4 meters, hitting the ground on the rear bumper, while the front was raised at a 45 degree angle on the truck. Touch the image to go to the original message The images of a six million dollar car making the pine on a transport truck soon became viral on social networks, and accounts like @johnclaywolfeshowThey shared them on Instagram accompanied by messages such as “Guess how many millions this little bird was worth.” In these photos you can see the transport operator inside the car at the time of the accident, observing impotent how a newly restored collection piece suffered damage that has not yet been evaluated at all but that, without a doubt, will mean an important disbursement for the person responsible.

Spain studies the viability of its first conventional aircraft carrier. We can expect sitting

There was a time when Spain was one of the great powers of the sea. Gone are those times when even The US feared, for various reasons, the Spanish Navybut these last times have resurfaced interest in strengthening security in this environment. Projects like him New Bac II Combat Ship They are ours and, now, Navantia has a new commission: studying the viability of the first conventional aircraft of Spain. It will not be easy, but the project is tremendously ambitious. Studying possibilities. A few weeks ago, and how we read in The countrythe Navy commissioned the public shipyard Navantia a viability study on the construction of an aircraft carrier. The shipyard must specify the technical characteristics of the ship and pass budget data that, subsequently, the Government must approve, but although all the details to be specified, as we read in The debatethere are already those who point to the modern French carrier Charles de Gaulle as inspiration. What Spain wants. Unlike the French flagship, the new Spanish carrier would not be a nuclear aircraft carrier, but it would have similar dimensions, with more than 260 meters in length and about 40,000 tons. What is clear is that, as we say, it will be the first pure aircraft carrier that the Navy will have, and this must be clarified. In 67, the US ceded the Labyrinth To the Navy, then Navantia built The ruinous prince of Asturias And, currently, we have the Juan Carlos i. The three have space for both helicopters and airplanes, but although they have a ramp, they have an important limitation: the airplanes that can land and deploy are the Stovl, which start the movement in vertical. And what is the problem? That limits the model that you can operate, and with current AV-8B Harrier II That they ask for the time, it is urgent to have an aircraft carrier that is able to house more modern fighters and without so much dependence on the United States. For example, the FCAS Developed together by France, Spain and Germany. If in the end it has a naval version, of course. According to EFEthe intention of the Navy is that it has a cover with capacity for up to 30 state -of -the -art aircraft. Officially, Juan Carlos I is a “Ampibio assault ship” India comes into play. As they point in Infodefensethe development of a traditional aircraft carrier (without being electromagnetic Like those who already operate China and USA) or with nuclear propulsion as the aforementioned Charles de Gaulle, it should not be a challenge for Navantia. “Simply” will be expensive, it will take time and will have a lot of steel, but the technology is more than settled. And here Navantia can have an advantage as “training”: Türkiye. Navantia has already made some designs for Türkiye, such as TCG Anadolu which became the jewel of the Turkish Navy crown and, as we read in Infodefensethe Spanish company would also be developing with Türkiye a traditional aircraft carrier of more than 300 meters. It will be something that serves to acquire even more experience in this type of vehicles. Strategic strength. Having a “pure” aircraft carrier is necessary for Spain in the current context of geopolitical tensions, even with allies that we considered as close as the United States. Within the European Rearme Processit is also something that makes sense, as much as countries and France and the United Kingdom have collaborated to “Add” your nuclear arsenals. An aircraft carrier, even A vehicle with a very expensive maintenanceit is an important element of deterrence due to its implications, something that we have recently seen in the Tensions in the South China Sea. To Japan, that for years It was a demilitarized nationalready started moving in this regard and has already presented its First aircraft carrier since World War II. For long. On the other hand, there is no hurry for this first Spanish aircraft carrier. Those hurries will arrive when the Harrier are retired, because the F35B Americans, but as we said, there is on its way to go. If everything is fulfilled, we would be talking about the first aircraft carrier for about fifteen years, but to reach that point the Navantia report must convince the government and he authorize its construction.

We have clicks on ‘Cancel Subscription’ in Correos without thinking. It is just what many cybercriminals expect

The entrance tray of our email usually becomes chaos. Or, at least, in a digital landfill where messages that we have not asked or want. The reasons are simple: in almost any online procedure, however innocent it may seem, they ask us for a Mail address. From registering on the website of your electric company to connect to the free wifi of a cafeteria, the email always goes ahead. Then there comes a time when we decided to put some order in this personal space. One of the most obvious ways to start is to stop receiving emails that do not interest us. And for this, the most logical step is usually clicking on that link that some messages include at the end. It can appear as “cancel subscription”, “if you want to discharge, click here” or the classic “Unsubscribe”. The promise is clear: pulses and that sender disappears. That click to stop receiving spam can take us just where we didn’t want to enter The problem is that, although this function is legitimate, it can also be used for malicious purposes. According to DNSFilterthere are hundreds of cancellation links that actually lead to sites potentially dangerous. And that turns a harmless gesture – whispering an annoying email – into an entrance door for much more serious problems. A real example of the ‘Cancel Subscription’ button that appears in many mails. In this case it is presented as ‘discharge’ When we click to cancel a subscription we are leaving the controlled environment of our mail supplier. It takes us to an external website, and there begins the risk. The link may not have us to lower us, but to confirm that our address is active. Like those calls that hang instantly: If you answer, you know you exist. Something similar happens here, but by email. With that simple verification, who is behind can bombard us with more advertising to launch attacks on Phishing or more elaborate scam attempts. And that’s not all. There are other even more dangerous possibilities. Some malicious links can try to inject malware In our system. It is technically complex, yes, but not impossible. It is also frequent that they redirect us to pages that mimic legitimate services. There, we can end up introducing our credentials or sharing personal data under a false promise of cancellation. At this point, the doubt is inevitable: and then what do we do? Do we resign ourselves to a saturated input tray of trash emails? The answer is no. There are alternatives that allow to maintain control without assuming so many risks. The first step, as we have already mentioned, is to be aware of danger. Understanding it allows us to act with head. Let’s look at some others. Use the integrated function of cancel subscription. Some mail services, such as ICloud, Gmail or Yahoo, incorporate this option directly into their interface. It is a safer alternative than clicking on the message links. They usually appear at the top or lower part of the mail, and are part of the supplier’s environment, not the sender. Gmail (above), Mail of iOS (center) and Yahoo Mail (below) include integrated buttons to cancel subscriptions from the app itself, without the need to open links inside the mail Mark the message as spam. Another option is to point out the mail as unwanted. The effect is immediate: the message disappears from the entrance tray and the system learns to block future similar emails. But be careful, it is convenient to use this tool only when we are clear that it is spam. Otherwise, we would be training badly to the system. Use disposable email addresses. It is a very useful third way, which we analyze in depth in the article ‘How I learned to use several email addresses to keep all my protected digital accounts’. Logic is simple: if the problem is to share our real direction, the most effective thing is to avoid doing so. And for that there are tools such as the “hide my email” function of Apple. The option ‘Log in with Apple’ allows you to hide your real email and use a random address that you can delete at any time from ICLOUD Those who use apple brand devices can activate this function by registering in a service. The system generates a random direction that forwards the emails to the main account. If you start receiving annoying messages, you just have to check which of those temporary addresses are coming and eliminating it. It is worth remembering that this function is free, but those who have Icloud+ They can create new ones addresses at any timenot only during the registration process. This gives even more margin to protect privacy and improve security. All this adds to the classical recommendations: maintain updated software and have a protection tool against malware. They are not absolute guarantees, but security layers that make a difference. No, we will not be 100% safe. No system is. But we can be informed and take some measures to avoid falling into the traps that cybercounts have.

If there is something that biologists did not expect to discover is that billions of moths look at the stars to orient

Imagine having to travel a thousand kilometers to a place where you have never been. Now imagine you have to do it at night, without GPS, or maps of any kind. To finish curling the curl, imagine that you only have one chance in your life to do so. You don’t have to imagine it because we are not talking about a person, but of moths. The annual pilgrimage of the Bogong moths. This is the feat that billions of Bogong moths (Infusa agrotis) They perform every year in Australia. And scientists have just discovered that they are oriented looking at the stars. This discovery, Posted in Nature magazineconverts the Bogong moth in the first insect of which you have a record that uses a stellar compass for long -distance navigation, a skill that until now was believed reserved for animals such as some night migratory birds. The trip of a life. Each southern spring, these moths undertake one of up to a thousand kiometers. They hatch in the warm plains of southeastern Australia and fly towards a handful of cold caves in the Australian Alps to spend the summer (a process called Estivation). When the fall arrives, those same moths undertake the trip back to their breeding areas to reproduce and, finally, die. The big question that has fascinated biologists for years is how they do it. No one teaches them the way. It is a round trip that each individual performs only once. A team of researchers, led by David Dreyer from the University of Lund, had already demonstrated in 2018 that the moths were sensitive to the magnetic field of the earth, Like other animalsbut they suspected there was something else. They had their eyes on the sky. A planetarium for moths. To confirm your hypothesis, The team designed an ingenious experiment. They captured migration during their migration and introduced them into a flight simulator. This device, similar to a small planetarium, held the moth allowing him to beat the wings and turn freely, while a sensor recorded his flight address. The team did several tests: They canceled the magnetic field: using a coil system, they created an environment without magnetic clues. Thus they made sure that any correct orientation was due to visual signals. They projected a natural starry sky: under an artificial night sky, identical to the one they would see in the time of migration, the moths were oriented persistently in their correct migratory direction: to the south in spring and north in autumn. They turned the sky 180 degrees: In the final test, the researchers rotated the projection of the starry sky 180 degrees. The response of the moths was immediate and amazing: they invested their flight direction almost exactly 180 degrees. They project random stars: to make sure they did not respond simply to the light, they projected an image with the same amount of stars and brightness, but randomly distributed, without forming recognizable patterns. In this situation, the moths flew disoriented, without a clear direction. Unexpected. These results demonstrated without a doubt that the moths not only see the stars, but use them as a true compass to maintain a specific geographical direction for thousands of kilometers. It was already known that other insects, such as players, use the Milky Way to orient. However, they do it to move in a straight line and quickly move away from a lot of manure, a short -term orientation and without a fixed destination. The achievement of the Bogong moth is much more complex. Use the stars to “discern specific geographical directions” and sail towards a “distant objective”, something radically different and much more sophisticated. A brain connected to the stars. The researchers did not stop in behavior. They also analyzed the brain of the moths and discovered visual neurons that responded specifically to the rotation of the starry sky. Interestingly, these neurons showed their maximum activity when the moth was heading south, regardless of whether it was spring or autumn, which suggests that they have a wiring neuronal system to detect a fundamental light blue orientation. This does not invalidate its magnetic compass. In another experiment, the scientists observed that on completely cloudy nights, when the stars were invisible, the moths were still oriented correctly. The conclusion is that the Bogong moth has an incredibly robust and redundant navigation system. It uses both the Earth’s magnetic field and a stellar compass, probably using a system to calibrate the other or to take over when one of the two fails.
