For years we have seen dolphins swim towards orcas without fear. Now technology has found out why

Until very recently, marine biology had an unwritten rule about the North Pacific: the orcas are the queens and dolphins, at best, a nuisance; and at worst, food for the orcas. However, science suggests that we were really wrongsince orcas and white dolphins have been caught collaborating with each other. It’s not a casual interaction.. It is a coordinated hunting strategy to catch the elusive Chinook salmon, documented for the first time thanks to a technological arsenal that includes drones and subjective cameras attached to the animals themselves. This is something that has been demonstrated in the study Led by Sarah Fortune, it focuses on northern resident killer whales, a subspecies that feeds exclusively on fish. For five years, researchers were seeing something that didn’t add up: the dolphins weren’t running away from the orcas, but rather deliberately swimming toward them. A collaboration with meaning. And these two species, which in theory should be far apart, do not collaborate just for the sake of it, but for a common good: the food. Dolphins, faster and more agile, act as scouts, locating schools of salmon. The orcas, with their brute strength and size, are responsible for the final capture of the largest specimens, impossible for a dolphin to hunt alone. The result? A shared feast. The orcas have been observed dividing the prey and allowing the dolphins to feed on the scraps and pieces that come off, in a kind of food “non-aggression pact.” Something that escapes everything we knew until now. How they discovered it. Observing this from a boat is really complicated, since seeing what happens underwater is almost impossible. To achieve this, the Fortune team used CATS tags. Some devices adhere to the orcas using suction cups and are like biological black boxes. They have the ability to record high-definition video in the deep sea, capture the acoustics around them and also have accelerometers and magnetometers to record depth and movement. A complete technological set that allowed us to obtain 258 documented events of dolphins interacting near the heads of the orcas. A silent mode. The acoustic analysis revealed the most fascinating fact about the intelligent behavior of these cetaceans. the orcasfamous for their complex use of echolocation for huntingreduced their own clicks and whistles when dolphins were present. The researchers’ hypothesis is clear: the orcas are outsourcing the sonar. They let the dolphins do the noisy work of finding the fish and they just listen and follow their marine “hunting dogs.” It is a brutal energy optimization. The orcas are saved the metabolic cost of searching and the dolphins gain protection and access to giant salmon that their jaws couldn’t process alone. The salmon crisis. This alliance may not be entirely natural, but rather a forced adaptation to a situation of food scarcity. Something that has meant that two predators have to learn to tolerate each other and cooperate to survive.

Apple TV has decided to swim against the current of all streaming platforms with a singular decision: not to put ads

The common note among all streaming platforms, beyond catalog details, seems to be in the search for profit by raising cheaper rates in exchange for advertising interruptions. Apple, however, seems determined to differentiate itself, which can undoubtedly bring benefits at an economic and image level. Which is exactly what would benefit you the most at this moment. No ads. Eddy Cue, senior vice president of Apple Services, has confirmed in an interview with Screen International that the company has no plans to launch an Apple TV subscription with ads. The refusal is not indefinite, but at this time that is Apple’s decision. Cue states that “we will not include them for now. It is not a forever negative, but at the moment there are no plans”, and it comes in a context where practically all of its large competitors are expanding their advertising strategies, with more and more rates with ads. Because. He streaming has entered into something we could call his “advertising era“But Apple wants to differentiate itself from there: it believes that if it can maintain a competitive price, consumers will value not having their content interrupted by ads. It is a position that connects directly with the brand’s DNA: control over the user experience, frictionless design, and a commitment to the perception of premium value even if the price is not the highest on the market. It is the same philosophy that applies with Apple Musicwhich has never competed with free, ad-supported versions. What is coming. Apple’s decision takes on its true dimension when you look at what is happening in the rest of the industry. One of the next trends that is going to reach us are ads that fire even if the content is paused. At the moment, in the United States it is Peacock that is experimenting with this way of displaying ads, as well as Netflix in some territories. Disney+ has also shown interest in incorporating it into its catalog. That is to say, what is coming for the more immediate future are increasingly invasive ads, in the style of YouTube or Spotify on their cheaper accounts, and which undoubtedly revalue decisions like Apple’s. Prices: competitive but quality. AppleTV It currently costs 9.99 euros per month in Spainwhile in the United States the price has reached $12.99. At first glance, it might seem expensive compared to competitors’ basic plans. But this is where Apple has executed an interesting positioning maneuver: it does not compete in the low end of the market, but instead offers premium features at an intermediate price. The key is that all content is available in 4K HDR quality with spatial audio, at no additional cost and without advertising interruptions. But also, there are no steps, no temptation to “improve” the plan. You pay a single fee and access the full experience. It’s a radically simple model in a market that has become increasingly (unnecessarily) complicated. Comparison with other services. Apple’s tactic is evident: for 9.99 euros, Apple TV offers an experience equivalent to competing premium planswhich cost between 13.99 and 19.99 euros. It is not the cheapest option on the market (that happens with the ad-supported plans of Disney+, €5.99, or Netflix, €6.99) but it offers superior features at an average price: accessible enough to not seem exclusive, premium enough to justify the quality. What Apple TV offers. If we stay with the numbers, Apple TV loses by a landslide: just 226 titles in its catalog, a microscopic figure compared to Netflix’s 5,720, Prime Video’s 5,354, Disney+’s 2,461 or even HBO Max’s 2,300. according to recent calculations. It only makes sense if the catalog is measured by the quality of the content. While Netflix and Prime Video invest millions in producing and acquiring piece-rate content, Apple TV focuses on fewer productions, but ones that convey exclusivity. Although Apple is far from having series with the impact of ‘Stranger Things’, its biggest hits (‘Separation’, ‘Silo’, ‘F1’), convey that feeling of “there is no filler” that compensates for the smaller amount. The decision to dispense with advertisements for the moment moves along the same lines: to provide the viewer with something that no one else does, an experience of enjoying the series without interruptions or noise. Even if you have to pay something more (and even though the platform accounts they are not at their best).

They don’t stop arriving tourists to swim with wild orcs

That clamor in many enclaves that has ended up calling as “tourist” He had reached the most remote places on the planet. They were no longer just the paradisiacal beaches, the “adventurer” went much further entering into areas such as Afghanistan, Iraq either Albania. In fact, Even Antarctica He had been the subject of the hordes eager for new experiences. What surely few ventured was that swimming with Orcas was going to become “must.” Dancing with cetaceans. I told it in A report the Guardian this week. Every morning in the window, a quiet coastal town of Baja California Sur, dozens of tourists in neoprene costumes go up Guided boats by local fishermen or by tourist operators from large nearby cities such as Cabo San Lucas or La Paz. Your goal: swim with wild orcs. An ecological crisis: What began as a unique and inspiring experience has become, according to many veteran experts and operators, into an uncontrolled activity that threatens both the safety of people and the well -being of animals. In absence of formal regulationup to 40 vessels can converge on the same group of orcs, especially between May and June, the months of greatest activity. The popularity of the phenomenon has exploded since 2019driven by networks, and has exposed A legal vacuum In Mexican legislation: although there are laws that protect threatened marine species, none explicitly prohibits swimming with dentated cetaceans such as … orcs. Invisible risks. Although there has never been a wild orca attack on humans, marine biologists warn that excessive and messy contact can cause defensive reactions. Plus and even more worrying: the cumulative effect of engines’s noise and the constant human presence on resident orc interferred by tourist activity. According to He explained to the Guardian Captain Juan Vásquez, with more than two decades at sea, these animals “will remember being harassed” and could stop visiting the area. Despite this, economic pressure is high: marine life tourism is a crucial source of income and few wish to limit it. Even vessels without insurance or license participate in these excursions, competing with better established operators that even guarantee meetings with orcs to ensure reservations. A pioneering plan. Given the lack of clear regulations, a group of responsible scientists and operators (including the Marine Biologist Georgina Saad and the documentary filmmaker Erick Higuera) have proposed the First Management Plan of Orcas in Mexico based not only on numerical fees but on the behavior of animals. The plan, which expects government approval this summer, would limit the interaction to Three boats per group of Orcas, with a maximum of nine daily vessels, and would require official permits. In addition, it states that guides and captains learn to identify Stress signals In cetaceans to know when to retire. Each Orca can be recognized by its unique dorsal fin, which would facilitate a record of sightings and interactions. Plus: Part of permits income would finance local patrols and training, establishing a sustainable model that prioritizes both conservation and education. Local tensions. However, the implementation of the plan is not exempt from controversy. Many captains and local families feel that they have not taken into account. Accuse that permits will end favoring large companies of Cabo and La Paz, displacing those who have lived from marine tourism for generations. In addition, they criticize that the plan is focused exclusively on The windowwhen both orcs and tourists already move throughout the peninsula. For SaadHowever, concentrating the regulation on the window is key to establishing a legal and operational precedent. “We can send the message that this is the only place where you can swim with orcs, and that is how it should be done. Everything else would be illegal.” A fine line. In summary, and despite the divisions, in the report they concluded that a large majority agrees that the solution is not to prohibit, but educate. Evans Baudinpioneer in this type of experiences and critic with the current “circus”, insists that the essential thing is to do things well: protect the orcs and continue offering respectful and safe encounters. For its part, the window is at a crossroads: either it becomes responsible tourism model or symbol of how a viral fashion can even damage the most imposing giants of the ocean. The success of the plan will depend not only on the rules imposed, but on the collective will to take care of what everyone says they want: creatures.

I have run, swim and worked with the Aqua Suunto. Under water I understood what these bone driving headphones propose

A common problem of aquatic headphones is that, in addition to not being Bluetooth for physical reasons, they are usually specifically aquatic. That is, little or nothing appropriate to use them out of water. The rest of sports headphones usually also have something in common: they forget the water. I do not talk about enduring sweat or rain, but really swimming, throwing you into a pool and forgetting everything except to breeze. That’s where the Suunto Aquabone driving headphones that are not only designed to function under water, but They have water as their natural state, But they are still dry in dry. I have tried running, on long walks, even at home while working. But it wasn’t until I took them to swim when I understood what I was trying to do with them. Thus they look when they take them out of our head. Image: Xataka. Its strength is not the sound (because it should not be) The first thing to understand of the Aqua is that they are not headphones to use. They use bone driving, a technology that transmits sound through vibrations that travel through the bones of the skull, specifically the temporal bone, to the inner ear. The auditory channel is free: you don’t need to have anything inside the ear to listen to music or a podcast. That provides a double advantage. On the one hand, comfort and safety outdoors: you can run or bike listening to your content without isolating yourself from the environment. On the other, an even more overwhelming logic underwater: nothing gets into the ear, there is no distorted sound, there is no sense of tamponade. Everything happens in that little transducer that rests on the ear and that, against all prognosis, it manages to keep listening even. That little button that stands out from the transducer is the one that serves to stop or continue the music (a touch), pass from song (two touches) or backward (three touches). Image: Xataka. Pogo load pins that guarantee pond but require their own case. Image: Xataka. And here with the connected load case. This works as an external battery for a pair of complete loads. Connecting a USB-C cable we will move to the wall charger mode. Image: Xataka. The surprising thing is that, despite this different way of transmitting the sound, the experience works. There is no isolation, but it is not what you are looking for here. You can hear the music, the podcasts, whatever you want … and you are still connected to what surrounds you. In water, where any other system fails, they continue to comply. Suunto has adjusted the equalization thinking about that: in outdoor environments and, above all, in immersion. Dry, sound is enough; In pool, better than expected. There are no forceful serious study, but a solid, coherent and much more refined proposal than I imagined. Running and swimming with them Before trying them in the water, I’ve been running with them months. Literally. I immediately noticed that the important thing was not as much the sound quality and the feeling of freedom: nothing inside the ear, nothing that falls out when moving, and the music always present without disconnecting from the world. Ideal to go through the city or by roads without losing sight or hearing what surrounds you. You didn’t have to adjust them every little, or worry about whether they loosen up. They simply worked. Besides, Its three buttons (two on one side, one in the other) allow to change volume or pass song. All great. But although they had convinced me, the best was yet to come. The posterior strip. It is flexible but without applying pressure it remains rigid. I don’t feel that I bounce in my neck. Image: Xataka. The first time I used them in pool I felt a certain astonishment. Not long, but when I did it used to be without music because all the previous solutions had seemed a commitment: they were uncomfortable, unreliable, or directly fragile. In fact it came from using some Sony NW-WS413 –With its humble 4 GB– since 2022. Image: Xataka. With those two buttons under the pogo pins we can do almost any action, combining pulsations, pulsation time, etc. Turn them on, turn them off, adjust volume, enter and exit sports mode, etc. Image: Xataka. With the aqua you do not have to juggle: The placing, you start the session from the headphones themselves (without the mobile, thanks to the 32 GB of internal storage) and throw yourself into the water. From the first length, something changes. Music accompanies you. And you keep swimming the same, without worrying about anything. There are no cables, there are no rubber ones that come out. The band that surrounds the head does not move. It does not loosen. It does not bother. It is as if it were not. But the most interesting comes later. These headphones listen to you swim At the end of the session, the data appears in the Suunto app: Posture, head angle, respiratory frequency, sliding in stroke. Technique metrics that I had never seen in headphones. And that, at least in my case, they told me something I didn’t know: that I breathe badly. Image: Xataka. Or more exactly, that I do it asymmetrically, with my head turning more to one side than to the other. They had never told me in the training. Nor had he noticed it. But there was the graphic. Yes indeed: There is no real -time feedback. What you get is a later readingas if you had a silent coach who takes notes while you swim. It is true that the app could go further in its interpretation of the data – phalta context, lack of concrete orientation – but as a starting point, impresses. It is another way of seeing your body in motion. To listen to you from within. For a future version it would be great to be able to … Read more
