“Who the hell thought that a movie could be shot here?”

by

When the team ‘The Odyssey‘ arrived at the Universal studios in Los Angeles after months of filming in Morocco, Greece, Iceland and Scotland, someone said: “How difficult is it going to be to film in a studio now?” Shortly afterward they were enduring Nolan putting some jet engines very close to them. It’s the Nolan method. And with ‘The Odyssey’ the method has included filming in the most inhospitable places. Who the hell is it going to be? Matt Damon, who plays Ulysses in this adaptation whose premiere will be next July 17, sums up this spirit with the question that was repeated every time they arrived at a new location: “Who the hell thought that a movie could be shot here?” The answer, obviously, was always the same person. It always occurs to him. I hate sets. Nolan seems to choose impossible locations precisely because they are impossible. According to your own philosophy A director’s job is to look for “magical moments in real places: a real sunset, a real castle.” For example: Nolan wanted to film in the Castello di Santa Caterina, in Sicily, as the setting for Ithaca. To reach the top you had to climb 275 meters along a path that was too narrow for the technical team. The solution was, after ruling out building an alternative road on the back slope, to install a scaffolding platform on the slope capable of supporting 200 people. Robert Pattinson and Tom Holland, of course, had to make the climb every day in “Roman clothing.” Any given Tuesday on a Nolan shoot. Ninety-one days, six countries, 610 kilometers of film. The Odyssey was filmed between February and August 2025 in six countries: Morocco, Greece, Italy, Iceland, Scotland and the United States. The total footage captured on 70mm IMAX film exceeds 610 kilometers and production wrapped nine days ahead of schedule. Despite this, the tour of different countries was, according to Matt Damon, an eternal unfulfilled promise: “Well, it will be easier in Iceland,” they said to each other. And then it rained heavily and it was bitterly cold. When they arrived in Los Angeles, the only environment they expected to be controlled, good old studio Hollywood, Nolan stuck some jet engines in their faces to simulate a storm. Tied to a boat. One of Matt Damon’s most memorable sequences is the one in which he was tied to a real mast, on a real ship, in the open sea. According to him, these types of challenges did not make him nervous, but rather made it easier for him to prepare: “Knowing that it’s going to be like this is a real gift for an actor because you already know how to prepare. It’s not about arriving on set and being told: ‘Oh, to shoot the scene we’re going to tie you to a mast.’” Bye bye. All the interviews that Matt Damon has been giving for months to talk about ‘The Odyssey’ have a nostalgic tone. He told GQ that this type of production “is disappearing” and that he was aware of having filmed something that would possibly never be repeated, at least for him, and that that made it “something finite, like a gift.” The counterpoint is that of Nolan himself, who claims that he has been hearing the same thing since ‘Inception’ in 2010, when he was told that filming in seven countries was impossible. “I thought we’d find a way to make it happen,” he says. And until now.

We thought that the problem of insomnia was on the mobile screen. Science points to the harmless five o’clock coffee

by

There is a ritual that many of us follow without questioning it. We arrived at five in the afternoon with our brains fried, we ordered a coffee—or a tea, or a Coca-Cola—and we continued. It’s the push we need to get through the rest of the day. What almost no one knows is that that five o’clock coffee may be sabotaging your eleven o’clock sleep. What we usually do when we don’t sleep well is point to our cell phone, stress, late dinner, or looping thoughts. We rarely point to the cup. And yet, for doctor Pablo Ferrero, a specialist in sleep medicine, the answer is there: “Caffeine is the number one enemy of good rest.” The chemistry behind the problem. To understand why caffeine is so disruptive, you have to know adenosine. It is a substance that the brain accumulates during waking hours and that, when it reaches a certain level, gives us that feeling of tiredness, that it is time to stop. It is, in a certain sense, the biological alarm of sleep. What caffeine does is to block adenosine receptors: Silences the alarm without disabling actual fatigue. The body continues to accumulate fatigue, but the brain stops perceiving it. The problem is not just that it is difficult to fall asleep. It’s what happens inside while we sleep. A study published in the Journal of Clinical Sleep Medicine found that a dose of 400 milligrams of caffeine consumed six hours before bedtime significantly reduced sleep efficiency. Other job in Neuropsychopharmacology was more specific: Consuming caffeine before bed reduces the amount of REM sleep, the phase in which the brain consolidates memories and regulates mood. More in depth. The numbers They are concrete and not very reassuring.: That dose can delay sleep onset by up to 45 minutes and reduce deep sleep—NREM phases 3 and 4—by up to 20%. Taken to everyday practice: if you have a coffee at 5:00 p.m. and go to bed at 11:00 p.m., your deep sleep can go from the usual 120 minutes to just 96. That’s 24 minutes less brain and physical repair. Nightly. But there is something even more disturbing: a scientific review published in the magazine Nutrients concluded that caffeine can reduce deep sleep even when the person sleeps eight hours continuously. That is, it is not enough to add hours. Quality does not always coincide with the perception of having a good rest. You can wake up thinking you’ve had a great night’s sleep while your brain hasn’t gone through the cycles it needed. Time matters. One of the most common mistakes is to think that afternoon coffee “no longer works” because you are used to it. Tolerance reduces the perception of the stimulus, but The half-life of caffeine in the body is between 4 and 9 hours: That means that half of what you drank at three in the afternoon is still active at eleven at night. And the problem is not limited to coffee. Caffeine is also present in some soft drinks, energy drinks, teas and chocolates, something that Ferrero expressly points out as a factor that goes unnoticed. It’s not just the breakfast cup: it’s the entire consumption circuit of the day. The broken clock. Caffeine, however, does not act alone. Ferrero points to another factor that can be even more decisive: schedule disorder. The body works through the circadian rhythman internal biological clock that regulates when we feel sleepy and when we are alert. When schedules constantly change—we go to bed at eleven Monday through Thursday and one o’clock on Fridays and Saturdays, and we get up three hours later on Sunday—that system loses synchronization. science back this up with data: Sleeping at irregular hours can cause insomnia, daytime sleepiness and alter hormone production, metabolism and eating habits, increasing the risk of diseases such as diabetes, obesity and depression. The impact don’t stop feeling tired Since while we sleep, the brain eliminates the beta-amyloid protein, accumulated during wakefulness and directly related to Alzheimer’s and other neurological disorders. Poor sleep is not just a tomorrow’s problem: it is a long-term investment—or debt. The motive is not innocent either. But the mechanism is more precise than is usually explained. The blue light emitted by screens suppresses the production of melatonin, the hormone that signals the brain it’s time to sleep. A study by the Barcelona Institute for Global Health warned that this overexposure directly alters the sleep-wake cycle. Just two hours of exposure to bright screens before bed can reduce melatonin levels by 20% or moreand the time to fall asleep can go from 15 minutes to more than an hour. Using a tablet before going to sleep can delay nighttime sleep by up to 96 minutes; that of a smartphone, up to 67. Harvard Medical School noted that “just a few minutes of screen stimulation can delay the release of melatonin by several hours and desynchronize the biological clock.” The problem is that we live in a society with increasingly irregular patterns: high light exposure at night, changing work schedules, screens until the last minute. We are sending our brain signals that it is still daytime when it is no longer daytime. So what works? Ferrero’s answer is not particularly glamorous, but it is supported by evidence. Going to bed and getting up at similar times every day—even on weekends—is the most basic and most ignored advice. Added to this is a dark, quiet and cool bedroom: artificial light and high temperatures send alert signals to the brain that make it difficult to rest. Avoid screens before going to bed—at least 30 minutes—and have a light dinner, without excess fats or spicy food, close to bedtime. For those who do not have insomnia, a short nap may be beneficial; The key is that it does not exceed 25 minutes so as not to disturb your night’s sleep. And in the face of anxiety or thoughts in a loop, Ferrero points out tools with scientific evidence: … Read more

If you thought that Renfe was taking… Germany is spending 100,000 million euros so that its trains arrive on time

by

We complain a lot about Renfe (and a good part of those complaints, with reason). But although it may seem otherwise, Germany has been neglecting its railway network for decades at decadent levels. And just as they count According to the Financial Times, only six in ten long-distance trains arrive on time. However, the country already has a plan in mind, a plan that involves investing some 100,000 million euros in solving its punctuality problem. The problem. In 2000, 84% of German long-distance trains arrived on time. Today that figure has fallen to 60%. Already last year, an analysis The Financial Times placed Deutsche Bahn, the German public operator, below even the most late railway operators in the United Kingdom. Just like account The German Transport Minister, Patrick Schnieder, even warned in March that the situation threatened to erode public confidence in the institutions. In his own words, he assured that if the State is not capable of guaranteeing basic services, “democracy is harmed.” How we got here. According to the media, this deterioration has been the result of a series of poorly made decisions over two decades. In the early 2000s, the German government considered taking Deutsche Bahn public. The plan never materialized, but to improve the balance sheet for that hypothetical exit, network maintenance was cut. To this was added that between 2005 and 2010 the budget for railway infrastructure was, adjusted for inflation, 20% lower than in the mid-nineties, according to calculations from the FT itself. The icing on the cake came in 2009, when Germany constitutionalized the so-called “debt brake“, which forced the State to balance the accounts every year. This caused investment spending to systematically lose the battle against social spending. The current state of the network. Just like account According to the FT, 16% of the assets of the German railway network are classified as deficient or directly inadequate. There are bridges dating back to the time of Kaiser Wilhelm II and signal boxes installed in the 1960s that are still in service. In fact, according to DB InfraGo, the Deutsche Bahn division in charge of maintaining the network, 80% of all delays are directly caused by deterioration of the infrastructure. You have to open the tap. In 2025, Chancellor Friedrich Merz took advantage of a constitutional loophole to create a fund of 500 billion euros to renew the country’s infrastructure over the next twelve years. The railway is one of its top priorities since, of that total, Deutsche Bahn has committed 107 billion euros until 2029. However, Philipp Nagl, CEO of DB InfraGo, recognize to the FT that needs at least 130,000 million to cover the accumulated delay. And as he comments, every year, more assets reach the end of their useful life. How it is being executed. The strategy is being extremely drastic, closing entire sections of the network for months to rebuild them from scratch, instead of patching section by section. Furthermore, it is an atypical way of doing things at Deutsche Bahn, which historically had a tradition of keeping lines open while carrying out construction work. “With that method it would take forever,” explains Nagl to the FT. The number of active works on the network has grown by a third since 2024, to exceed 28,000 in 2026. The immediate consequence is more chaos in the short term. And the punctuality goal has been lowered to 70% and postponed until 2029. A real example. In one of the busiest corridors in the country, the one that connects Cologne with the Ruhr Valley, along which up to 280 trains circulate daily, the line has been closed since February. According to account In the middle, the 55,000 regular travelers must resort to more than 200 replacement buses, many of them stuck in traffic jams. In return, 81 kilometers of track, 50 detours and 12 stations are being renewed in five months. The person in charge of the project, Arno Jaeger, defined the medium as “a monumental task” with a budget of 800 million euros. To speed up the work, specialized heavy machinery is used. In fact, one of the machines, colloquially nicknamed Mamut, renews two kilometers of track per shift, four times faster than if they did it through the conventional method. It’s about operators. Beyond Deutsche Bahn, there are private competitors waiting for their chance. And just as account FT, FlixTrain, the railway arm of the Flix group, has reserved 2.4 billion euros to buy up to 65 high-speed trains that it wants to deploy from 2028. The Italian high-speed operator Italo has also announced its intention to enter Germany with an investment of up to 3.6 billion if it gains access to the network for several years. Both point to 2028 as a key year. Cover image | Deutsche Bahn In Xataka | The Spanish west has a forgotten train that it wants to recover. The problem: neither Madrid nor Europe are interested

Russia thought kyiv would fall within days. Four years later, the war in Ukraine has just “passed” the First World War

by

In 1914, millions of Europeans they were convinced that the war would end before Christmas. In fact, the expression “home by Christmas” became popular between soldiers and civilians who believed that the conflict would be rather brief. It ended up lasting more than four years and transforming Europe forever. More than a century later, the Ukrainian war has already grown longer. From days to historical milestone. When Russia launched its full-scale invasion in February 2022, the Kremlin expected a swift campaign that would culminate in the fall of kyiv within days. More than four years later, the reality is exactly the opposite: the war has reached the 1,569 days duration and has already officially surpassed to the First World War. What began as an operation designed to quickly overthrow the Ukrainian government has transformed into one of the longest and most consequential conflicts in recent European history, to the point that many Ukrainians they contemplate with concern another historical threshold even more distant: the duration of the Second World War. The inevitable comparison with 1914. The historians warn that comparisons with world wars have obvious limits due to the differences in scale, number of countries involved and volume of casualties. However, they consider that the war in Ukraine shares enough features with the First World War to become its closest parallel in more than a century. Both began lightning offensives aimed at achieving a decisive victory within a few weeks. Both the German advance to Paris in 1914 like the Russian push towards kyiv in 2022 came close to achieving their initial objectives before being stopped and forced to retreat. The return of trench warfare. After the failure of the initial offensives, both conflicts drifted towards long static fronts where artillery dominated the battlefield. The images from the trenches of eastern Ukraine quickly evoked scenes from France and Belgium during the Great War. Soldiers barely separated a few hundred meterscontinuous bombardments and small infantry assaults became the daily routine. The firepower forced combatants to bury themselves underground to survive, reproducing a pattern that seemed to belong definitively to the past. Drones change the rules. The main difference between both wars came from the air. The drones profoundly transformed the battlefield and ended up making even traditional trenches vulnerable. Permanent surveillance from the sky and the ability to attack with precision forced the replacement of long defensive lines by small scattered sheltersdifficult to detect and more resistant to attacks. In many areas, any open-air movement can be located and attacked in a matter of minutes, turning large areas of the front into veritable death zones controlled by unmanned systems. Tanks, bunkers and dispersal. Technological evolution has also reduced the prominence of some weapons that for decades symbolized modern warfare. Tanks, feared during the early stages of the invasion, have become on easy targets for drones and they appear less and less near the line of contact. Meanwhile, soldiers invest enormous efforts in building shelters each time more sophisticated and profound. Some bunkers incorporate specific designs to absorb explosions and increase the chances of survival, reflecting the extent to which physical protection is once again a vital issue in an attritional conflict. Destruction reminiscent of the last century. Although the casualty figures They are very inferior Like those of the First World War, the visual devastation is eerily familiar. Destroyed forests, towns reduced to ruins and fields covered in craters constantly appear in images captured by reconnaissance drones. Various military analysts hold that the lethality of the Ukrainian front is close to that of the great battles of a century ago, not because of the absolute number of deaths but because of the constant danger faced by those fighting on the front lines. Stagnation and the search for a way out. The slow pace of progress illustrates the nature of the conflict. In some recent operations, Russian forces have progressed at a pace even slower than that recorded in some of the most stagnant battles of the First World War. With negotiations practically paralyzed, neither side has yet found a formula to break the balance. Ukraine tries to weaken Russian economic capacity through attacks against energy infrastructures and oil companies while flooding the front with thousands of attack drones, seeking to impose unsustainable costs on the adversary. The final paradox is that a war that began with the promise of quick victory increasingly looks like to the Great War: a prolonged struggle of attrition, marked by technology and with no clear end in sight.

They have found a 1968 vampire film that they thought was destroyed for being too scary. Now we can check it

by

A projectionist at a cinema in the British county of Dorset opened a rusty film can in a warehouse. It was an episode of a series that had been missing for years and about which the legend had spread that it was too scary. However, the explanation for its disappearance was much more mundane: the same reasons why seventy percent of British television programming at the time had disappeared (or so it was believed). What they found. On May 23, the film preservation organization Film is Fabulous! announced the discovery. Darren Payne, a projectionist and technician who runs the 35mm film exhibition collective ‘Dirt in the Gate Movies’, commissioned a small collection of film reels that was about to be destroyed. One of the cans had handwritten, without further detail, ‘Late Night Horror’. “I’m a horror fan and the title resonated with me,” Payne explained. He took the film home, screened it on his own computer, and what he saw left him speechless: the first episode of a series that had been believed to have been destroyed for more than half a century. Nothing like a vampire. ‘No Such Thing as a Vampire’ is the pilot episode of ‘Late Night Horror’, a series of six 25-minute episodes that BBC2 broadcast in the spring of 1968. It was the network’s first color horror production, although the recovered print is in black and white: a 16mm secondary run made for international distribution before the color masters were removed. What is it about? The script was based on a story by the great Richard Matheson, a writer to whom the fantastic Anglo-Saxon owes, among other things, the founding novel ‘I am legend’ and 16 episodes of the original series of ‘The Twilight Zone’. The plot follows a woman who appears paler and weaker every morning, with marks on her neck, while her husband and the family doctor discuss whether or not there is a vampire in the town. The answer is the kind of twist that Matheson was adept at: rational, disturbing and with a bitter aftertaste. Who is behind. The direction was, amazingly, by a woman: Paddy Russellwho at that time was already an exceptional figure at the BBC. She was the first female plant manager of the entity and one of the first two directors of the chain, at a time when the technical teams were dominated by men to the point that the name with which she appeared in the reports (Paddy is a diminutive of Patricia, but can be perceived as an acronym for Patrick) also functioned as a kind of protection. Russell directed two of the six episodes of ‘Late Night Horror’: the first, now recovered, and ‘The Corpse Can’t Play’, the only one that was already known. With this discovery, his complete work in the series once again exists. The episode aired on 19 April 1968 at 10:55 pm and attracted 1.8 million viewers, the highest audience of the series and one of the highest BBC2 had recorded since its launch in 1964. The legend. This is where we must clarify the legend of “the episode that was destroyed because it was too terrifying”, a rumor that has been spreading on the internet mainly due to the creepy credits of the series. Actuallybetween the mid-1950s and mid-1970s, the BBC eliminated between 60 and 70% of its television production due to company policy: two-inch tape masters were very expensive, union contracts prohibited more than one or two rebroadcasts, and there was no legal obligation to archive the material. It was not until 1981 that the BBC began to retain its archives. ‘Dr. Who’ is the case of the most famous series with episodes lost due to this policy. ‘Late Night Horror’ disappeared, exactly like hundreds of other shows disappeared. That is why a 16mm copy has been found: it was certainly not in BBC warehouses. With this international material, lost episodes of ‘Doctor Who’ have also been recovered. It will be seen. At the moment the BBC is investigating whether it is technically possible to recover the original color through chromatic restoration processes, since the episode was recorded in color but only survived in black and white. And there will be a grand premiere: on September 20, 2026, as part of Grindfest. It will be the first time the episode has been seen since its only showing in 1969. Who knows if they will appear in some forgotten warehouse. Like a horror movie.

We thought that solar parks were a death trap for birds. 19,000 hours of video and an AI have just dismantled the myth

by

During the last decade, the story of the energy transition has carried a shadow of suspicion. The visual image of a sea of ​​glass and silicon, dark and geometric, made us believe that the installation of large solar parks was equivalent to sterilizing the earth. We imagined a devastated ecosystem, an industrial desert where the hum of transformers chased away any trace of fauna. It seemed the inevitable price to pay for decarbonizing our economy. However, when science has decided to turn off the noise of public debate and turn on the cameras to observe what really happens under those plates, the result has broken all schemes. The AI ​​that watched the sky. One of the deepest fears was the theory that solar panels acted as a lethal mirage for birds. To clear up this mystery, an exhaustive study published in the scientific journal Diversity has resorted to the latest technology. A team of scientists installed high-definition cameras at five photovoltaic plants in the United States (spread across the desert Southwest, Midwest and Northeast) and collected more than 19,000 hours of daytime recordings over several years. Given the human impossibility of reviewing such a quantity of footage, the researchers developed an Artificial Intelligence model (MODT) designed specifically to detect and track moving objects. After filtering more than 4,000 hours of video, AI and human reviewers identified 68,646 bird appearances. An unprecedented find. Not a single bird collision with solar infrastructure was confirmed in all the observations analyzed. Far from colliding or being disoriented by the supposed “lake effect” of the panels, the images showed that the birds integrate the solar plant into their daily lives: they fly over it (an activity that accounted for around 54% of the observations), cross it underneath, look for food on the ground, preen and even nest in the metal structures themselves. More life inside than outside. Crossing the Atlantic, scientific evidence supports this coexistence. According to a study published in AgricultureEcosystems & Environmentcarried out by researchers in Poland, small-scale solar farms located in agricultural environments significantly increase birdlife diversity. After analyzing 43 photovoltaic parks and comparing them with 43 neighboring control areas, Polish experts documented that the vast majority of species improved their presence. Except for the meadowlark, which showed a negative reaction, species typically threatened in rural areas such as the wildcatcher or the northern stonechat appeared in much larger numbers within the park. As the study explains, the facilities provide them with safe breeding areas, tall grass (which is mowed late or left to grow) and fences perfect for perching, singing and monitoring their prey. This reality is identical in our country. As we recently explained in Xataka, Spanish photovoltaic enclosures are acting as authentic sanctuaries. The data collected by the Spanish Photovoltaic Union (UNEF) and audited by the environmental consulting firm EMAT in 2025 show an irrefutable pattern. In Minglanilla (Cuenca), 32 species of birds were found inside the solar plant compared to 19 in the external agricultural area. In Revilla Vallejera (Burgos) the balance was 39 versus 34, and in Trujillo (Cáceres), 31 versus 25. Furthermore, these enclosures not only house common birds, but have become home to protected or seriously declining species such as the curlew, the little bustard or the lesser kestrel. What is the secret of this explosion of life? The answer requires changing perspective. These parks are not being installed on virgin forests, but on fields that have been subjected to intensive agriculture for decades. According to Martín Behardirector of Studies and Environment at UNEF, by building a solar park a de facto “ecological exclusion zone” is created where tractors, pesticides and herbicides disappear. Human silence attracts weeds; weeds to insects; insects to small birds, and these to large birds of prey. The key: active management. If energy companies limit themselves to fumigating the land or sweeping the brushcutter to leave the ground bare for convenience, the park will effectively be an inert desert. For flora and fauna to return, will and active management are required: using native seeds, leaving wild ecological strips on the margins, allowing extensive grazing for natural control of forage and avoiding agrotoxins at all costs. The data has spoken. We had been fearing for years that solar panels would destroy life in the countryside. It turns out that, managed with rigor and sensitivity, they have the exact power to do just the opposite: heal the ecological wounds of centuries of agricultural exploitation and give nature a voice.

We were already using fire 800,000 years earlier than we thought

by

He dominion of fire isWithout a doubt, the greatest turning point in the technological and evolutionary history of our lineage. It gave us warmth, it scared away predators and, by allowing us to cook food, it triggered the development of our brains and also our own lives. Until now, the scientific consensus placed the strongest evidence of its early use at around one million years, although this is no longer the case. A new study. a new study published in PLOS ONE takes us to Wonderwerk Cave, in the northern Cape province of South Africa. This site was already “old acquaintance” for paleoanthropologists, since in 2012 a team demonstrated the existence of fire on site in layer 10 of the cave, dated to approximately one million years. And this is important because from here the consensus was created about when humans discovered fire. But the story didn’t end there. The new study has descended one more step in time, specifically to layer 11 of the same cave and there they have found burned bones with an age that ranges between 1.07 and 1.79 million years. And it is vital. The location of the remains is vital, since they were found 30 meters deep inside the cavern. This completely rules out that the fire marks are the product of a random forest fire or a lightning strike, but rather that someone had to carry those flames there after learning to control the fire. A new debate. The evidence that suggests that our past knew how to make fire is much later, since in sites such as Gesher Benot Ya’aqov In Israel, total control of technology is already shown. What this new finding raises is whether these Homo erectus early people did not know how to light a fire from scratch. What is proposed is that instead they were “thieves” of nature, since they took advantage of natural fires caused by lightning or volcanoes, collected the embers and transported them inside the cave to keep them alive as long as possible. A technique that, although it seems simple, entails great cognitive and social complexity. The technology. If the fire in layer 11 had not been confirmed until now, it is because it is incredibly difficult to distinguish a bone burned almost two million years ago from a fossilized bone that has undergone chemical alterations. And it is no wonder, since with the passage of millennia, diagenetic processes such as fluoridation or the accumulation of manganese can darken the fossils, giving them a false appearance of having been carbonized. But now we have very important tools, such as luminescence techniques combined with Fourier transform infrared spectroscopy, which allow us to reveal chemical secrets at the molecular level. A new paradigm. The experts who have given their opinion on this study through the Science Media Center Spain such as Joaquín Panera or researchers specialized in fire such as Aitor Burguet-Coca agree in describing the methodological protocol as “innovative”, highlighting that it opens the door to reevaluate huge collections of fossils in other sites, such as Koobi Fora in Kenya, where there are ambiguous signs of fire 1.5 million years ago.

We thought catnip was cats’ favorite drug, there is another plant that they like more. And it’s not because of the high

by

Cats love catnip, just look at the shelves of any pet store full of toys with catnip. They sniff it, bite it, roll on the floor and even drool, as if they were entering a kind of trance. We believed that this herb was our kitties’ favorite “drug”, but researchers have discovered that there is another plant that attracts them even more. The experiment. A group of Japanese researchers set out to discover which plant attracts cats the most, catnip or matatabi (also known as silvervine). To do this, they combined three trials: free cats in a garden with fresh plants, free cats with a brick impregnated with the extract of both plants and cats in captivity with impregnated papers. The researchers recorded on video the episodes of self-anointing, which is when they rub each other and make “croquettes” near the different plants. The matatabi wins by a landslide. All groups of cats that participated in the experiment showed a clear preference for matatabi. In the case of free-ranging cats that had access to both the plants and the impregnated brick, almost all self-anointing episodes occurred with the matatabi. Among the captive cats, 15 responded only to the matatabi, three to both, and three sniffed a little but did not rub against them. The curious thing is that the chemical analysis revealed that catnip was much more powerful (it contains much more nepetalactone) than matatabi, but despite this the cats had a very clear preference. Masao Miyazaki, project leader, states in Phys that One might expect that a plant containing more active compounds, and compounds that clearly work in laboratory tests, would trigger a stronger behavioral response under free-choice conditions. But that’s not what we observed.” The Overwhelmed Smell Theory. The authors’ hypothesis is that catnip, especially when fresh, releases an excessive amount of these compounds and makes the smell too intense, hence cats prefer matatabi because it is milder. This fits with an anecdote in ‘The Gardeners’ Dictionary’ published in 1789, which observed that cats preferred catnip when it was wilted rather than fresh, which reinforces the idea that it can saturate their senses. A biological reason. Rubbing against these plants is not simply to get high, it also hides an evolutionary purpose: it acts as a defense mechanism against mosquitoes and other parasites. When you rub your face and body with the plants, they become impregnated with the substances (iridoids) that they release, acting as an insect repellent. The reason they prefer matatabi would be because it offers more reliable protection as it produces a more complex mixture of iridoids, especially when they nibble on the plant. That is to say, it is much better against mosquitoes. Image | Sergey Dvorkin, Pexels In Xataka | We have been vaccinating our dogs and cats every year all our lives.

Someone thought it was a good idea to bring a Bluetooth device called “Bomb” onto a plane. What had to happen happened

by

Imagine that you are sitting in that modern torture chamber that we call “economy class” on a transcontinental plane when, after an hour in the air of the eight-hour trip from New Jersey to Mallorca, the aircraft turns around to land at the point of origin because the bomb threat protocols are activated. Now stop imagining because that is precisely what happened this past May 30 when the United Flight Boeing 767 that covered the Newark – Palma de Mallorca route thad to turn around with 12 crew members and 190 passengers of which one was the owner of a Bluetooth device with a peculiar name. “Bomb”. The “Bluetooth bomb” He United Flight 236 It should be just another conventional flight, but those who took the one last Saturday experienced an unusual adventure. When the ship was flying over the Atlantic and in a period Between 60 and 90 minutes after takeoff, someone noticed a disturbing detail: searching for Bluetooth networks, They found a device called “BOMB”. If someone was carrying a bomb with a Bluetooth connection, I highly doubt it would be visible to everyone and, on top of that, it would be called “Bomb”, but it was enough for the situation to explode. The crew, using the public address system, repeatedly asked that the Bluetooth devices be turned off, even threatening with turning around, but after seeing that there were still some lights left and that the “bomb” was among them, the maneuvers began. In coordination with the company’s operations center in Chicago, it was decided that it was best to declare a state of bomb emergency and return to Newark. The plane landed as if nothing had happened, but on the ground there was a significant police and security deployment that forced the passengers to vacate the ship, leaving their hand luggage behind. Image | Flightradar24 As part of the procedure, it was now the security forces that were going to be in charge of inspecting that luggage again. It has not really emerged what the device was, but what is clear is that there was no real explosive device. United has not given detailsbut different media indicate that a 16-year-old passenger had a device named with that name. Some say it’s a Fitbit, others say it’s a Bluetooth speaker. No details have been given about the consequences. that the passenger will have to face and everything has remained an anecdotal situation and a story that those 212 people will tell at some point. Now, there are interesting readings. The first is that there are devices for which you can change the name of the Bluetooth connection. For example, we can call our cell phone whatever we want, just like Wi-Fi networks, but there are others that are not easy to change the name of. A speaker or headphones usually have the name they come from the factory, unless they have an app that explicitly allows you to change the identifier. This is important because there are speakers like the Bombbox from JBL and, above all, the Hama Bomb 3.0 that have ‘BOMB’ in the name. Obviously, it doesn’t just say that and there are numbers and the brand, so it would be easy to deduce that it is a totally different device than a bomb. Also, if this were the case, the device would be turned off and not searching for Bluetooth all the time, so what makes the most sense is that it is a mobile phone with that ‘nickname’ for Bluetooth. That said, when the crew asked to disconnect the Bluetooth, if the person had headphones on they might not even notice and, if they did, it was a message that could be interpreted as “put the phone on.” airplane modeThere are cell phones that, when they activate airplane mode, deactivate all wireless communications, but there are also those that only deactivate Wi-Fi, the mobile network and leave Bluetooth to allow connection with headphones. This is for trying to find an explanation for a bizarre story like few others that had a happy ending for the passengers, being able to board a new flight the morning of the next day, but which could be very serious for the funny or clueless owner of the device. Because it is one thing to take longer to take off, but having a plane turn around, relocate all the passengers and the company pay compensation… is not cheap. AND I’m sure someone at United Flight isn’t happy at all.nor were those who were on that flight and who had zero information about what was happening, even having to go to reddit to find out about the movie and report the company’s compensation: a $15 bonus to spend on food. Moral: take a look at what your devices are called. In Xataka | Airplanes have circular windows for a reason. It took two plane crashes to find out.

You thought you ended up liking beer out of habit. Science has seen many ways to acquire this taste

by

There are many people who cannot stand certain foods, such as the hated broccoli or cauliflower, which for some is inedible and they do not even understand how someone could like that. This also happens when you first take a sip of coffee or a drink of beer whose strong flavor can put anyone off. However, a few years later, that same bitter drink is part of the daily routine or even a pleasure, as is the case with beer. How is it possible? This is the question we can ask ourselves about these sudden changes in taste, and the truth is that it is quite documented under the term “acquired taste“. These two words explain not only why our preferences change, but also how our brain is capable of rewriting its own danger alerts to transform rejection into a reward. Survive. To understand why we learn to love certain flavors, we first have to understand why we hate them in the first place. Much of the blame lies with food neophobia, which is nothing more than the fear or refusal to try new foods, since although in childhood we usually label it as “being picky”, from an evolutionary point of view it is a sophisticated defense mechanism. If we look back to prehistory, children put anything they found in their mouths; like a new berry or a bitter plant, they were very likely to end up poisoned. That is why any bitter taste for our brain is a sign of toxicity and, therefore, we must reject it. Although this is not the case, as is the case with many foods. It’s genetic. The interesting thing is that this rejection is programmed from the factory and has a very strong genetic component. This has been seen in studies done on twins who demonstrated that childhood food neophobia is highly heritable, estimating that heritability by up to 72% during early stages. This genetic predisposition is often associated with a lower acceptance of diverse flavors and textures, and a more restrictive diet in childhood. But genetics only deals the cards with which we will later play in a great environment, since 28% of the probabilities leave a margin for environmental factors. Hacking the brain. The question here is that if biology has programmed us to spit out coffee because it is bitter… Why are many people hooked on it? The answer lies in the brain mechanisms of flavor learning and memory, since our brain constantly evaluates the post-ingestion consequences of what we eat. This is what explains, for example, that if we vomit a lot after eating a tortilla, we begin to put it aside later because we associate it with illness. But if we drink something bitter and, instead of getting sick or dying, we get a boost of energy like with caffeine or a social disinhibition like with alcohol, the brain updates its database and points out that the risk was worth it and that we achieved something positive. Repeated exposure. In order to introduce new foods into a diet that is being developed, as occurs in children, science suggests that Consistency destroys this disgust that generates. However, visual exposure alone is not enough to break this ‘phobia’, rather repeated oral contact is necessary for the nervous system to adapt and accept the food. To facilitate this process, humans have thought of techniques such as, for example, sweeten foodand that is why the fact of adding sugar to coffee or drinking it with milk arises. This acts as a neuropsychological bridge to signal to the brain that these are safe calories. The social model It is one of the most important tools to intervene in our tastes. Here studies in infants suggest that seeing parents enjoy an unfamiliar food significantly increases acceptance in babies. And the reasoning is quite simple, since if the adult eats it and does not suffer damage, the food is considered safe to continue eating. And as you grow up, a large part of the flavors acquired in adolescence, such as beer or traditional dishes, are adopted because they are strongly linked to contexts of socialization and group acceptance, since if a friend takes it and nothing happens to him, it is because everything is fine.
