A simple gadget is making a species evolve live and direct: hummingbirds

During the late 1820s, Rene Lesson visited many times the ornithological collection of François Victor Masséna. Every morning, he crossed the doors of the Parisian palace of the Dukes of Rivoli and immersed himself in the more than 12,000 species they had accumulated there. Some say he fell in love there. Sometimes, just before immersing himself in work, he would come across a very young woman Anna d’EsslingMasséna’s wife. Lesson, who was well aware of his social situation, never said anything; but in his papers he described Anna as “a woman of exceptional beauty, elegance and education.” I imagine that, for this reason, when he discovered the amethyst-headed hummingbird among the Duke’s specimens, he thought of her. I imagine that, for this reason, Lesson named it after him. What I can’t imagine is what the French ornithologist would think if we told him that we were “evolving” the hummingbird he gave to Anna until we changed it forever. But that’s how it is. The evolution live and direct. I came to this story (and Global Change Biology study which supports it) thanks to a bluit by Carlos Cabido. It is, as the evolutionary ecologist says, “another case of rapid evolution that has generated observable adaptive changes in a very short period.” The “smoking gun.” But let’s start at the beginning: researchers at the University of California Berkeley analyzed the population expansion and the morphological changes in the beaks of hummingbirds in relation to a very specific device: the feeders that, since the 1930s, have been used on the west coast of the United States. These are simple sugar water dispensers, but (always according to researchers) they have caused a series of very striking changes. What changes? On a regional and temporal scale, “the density/use of feeders appears as the best predictor of population expansion”; well above other variables analyzed. This means that the installation of these dispensers is the key to the expansion of hummingbirds. Linked to that, researchers they observed significant changes in the morphology of the beak: it has become longer (to better access the feeder) and sharper (in a context where territoriality is becoming more important because it is linked to a very concentrated resource). And all this in a couple of decades. That is, in about ten generations. Why is it important? Above all, because it is one more example that a cheap, massive and standardized device (if it creates a new food environment) can reconfigure body structures and behavioral repertoires. And, beyond all that, because it shows that, if environmental change is intense and sustained, natural selection works like a shot. However, all that glitters is not a hummingbird. In fact, Anna’s hummingbird is almost an exception. As far as we know, countless hummingbird species They are suffering (and big time) the changes linked to the Anthropocene: although the Anna is growing, its first cousins ​​are in clear decline. And yes, it is our fault. Yeah this study shows that we have great power to change nature, the overview reminds us that “with great power comes great responsibility.” Image | Robert Bottman In Xataka | The domestication of cats remains a mystery. But we are closer to knowing where and why it happened

finally an AI gadget that doesn’t make me wonder why it’s not just an app

When in Xataka They offered me to try the Plaud Note Promy reaction was predictable: “another AI gadget that can be an app.” For a couple of years we have been seeing technological gadgets that promise to change our lives thanks to AI, sometimes with terrible resultand in general being solutions in search of a problem. But the Note Pro surprised me. Not because he does magic, but precisely because he doesn’t try to do it. This design only makes sense when you have it in your hand The product photos are very deceiving with this device. On the screen it looks like any other piece of junk, just another aluminum rectangle. When you take it out of the box, the reaction is to say “how cool is this.” It is literally the size of a credit card and just 3 millimeters thick.. We are not talking about “fine to be an engraver”, but fine, period. It’s ridiculously fine. Here, next to the AirPods Pro case to size it better. Image: Xataka. The first thing you do is try to fold it, because your brain doesn’t process that something so thin can have four microphones, 64 GB of storage and battery for 30 hours of continuous recording. The brushed aluminum finish is impeccable, with the kind of quality that makes you think of Apple. And I say this as criticism and as a compliment: They are clear about who they are copying, and they do it extraordinarily well. Well, that’s ridiculously fine. And well finished. Image: Xataka. The less than one-inch AMOLED screen is a detail that seems superfluous until you use it. It is not to watch videos, but to confirm at a glance that you are recording, how much battery you have left, and if you have marked any highlight. Nothing more, nothing less. It is design with purpose, not ornamentation. The screen has its purpose beyond being an indicator of the remaining battery. Image: Xataka. The uncomfortable question: why not just use an app? This is where it gets interesting. Because yes, you have options like Otter.ai or the native recorder on your mobile with automatic transcription. They are free, or almost. They already live in your pocket. Why on earth would you want to spend $179 on a separate thing, plus a subscription that ranges from $20 a month to $250 a year? The honest answer is that for most people, it doesn’t make sense. If you record one meeting a month, use your mobile. If you need to transcribe from time to time, Otter is more than enough for you. But if you live in meetings, briefingsinterviews, calls with clients, presentations… the equation begins to change. The Note Pro frees you from cell phone dependenceand that is more valuable than it seems a priori. When you record with your cell phone, that cell phone is busy. On many occasions you cannot consult documents, take notes in parallel or respond to an urgent message. And above all, you can’t let it run out of battery just when you need it most. The Note Pro is a single function deviceand that specialization is its strength. It charges via magnetic pogo-pin connector. Image: Xataka. 🔌 Image: Xataka. The recording quality also makes a difference. The four MEMS microphones pick up voices up to five meters away with remarkable clarity, and the AI ​​processing to separate speakers works surprisingly well. In tests in meeting rooms with six people, it correctly identified each voice without the need for anyone to speak in ordered turns. Otter.ai on my mobile usually works great, but tends to mix voices if two people are talking at similar volumes. But let’s be clear: the gap is not abysmal. Modern apps also work well. The advantage of the Note Pro is cumulative, not punctual: better battery, better audio capture, a device that you can leave on the table without worrying about interrupting notifications, without anxiety in case someone calls in the middle of recording. And also, if you have an iPhone with MagSafe, there is a wallet with which you can stick the Plaud to it and even be able to record calls. The Plaud Note Pro inside your MagSafe wallet. Image: Xataka. Also here. Image: Xataka. The button highlight: small detail, big difference There is a feature that sounds trivial on paper but that in use I have found to be extraordinarily useful: the highlight. During a recording, if someone says something important, you press briefly and the system marks that moment. Not only to locate the fragment later, but for the AI ​​to prioritize that information in the summaries. Bright. I’ve tried this on long presentations and the difference is brutal. Without highlightsthe summary gives you a medley where what is important can be diluted between ramblings. With highlights strategic, the summary goes directly to the decisions, commitments, critical points. It’s an elegant way to guide AI without having to write prompts after. Kudos to whoever had this idea. The AI ​​behind it: powerful but expensive Hardware is only half of the equation. The magic happens in the Plaud app, which processes the recordings using models from Google, OpenAI or Anthropic. You can choose which model to use for each transcriptionwhich is a level of control I wasn’t expecting. When starting a transcription we can choose between automatic and personalized transcription. If we choose the second, we can even choose the model to use. And it already includes the recently released Gemini 3 (although in beta). Image: Xataka. The different views of a transcript: summary, geolocation and recognition of who the key person is (if introduced at the beginning), key points, thematic index and complete transcript. Image: Xataka. The transcription is excellent. Comparatively better than Google Meet or Zoom in my experience, although that may depend on accent and environment. What is really interesting are the summary templates: you have everything from meeting minutes to Q&A format for interviews, to class notes or … Read more

Sam Altman spent 6,500 million to create a Gadget from AI next to Jony Ive. Now they face a problem

In September 2023, Sam Altman, CEO of Openai and Jony Ive, former chief chief in Apple, gathered to devise a revolutionary device they called “the iPhone of the AI”. They were serious because this year Openai bought the Startup of IVE for a whopping 6,500 million dollars. A halo of smoke Mystery has surrounded this collaboration since it was announced and now that new news arrives is because the project has problems, some more serious than others. The “problems.” They tell it in Financial Times. Openai wants to launch its mysterious Gadget Superventas next year. However, sources close to the company ensure that the project has encountered critical problems that could delay its arrival. The team is having difficulties when deciding the personality that the wizard will have, something crucial for a device designed to always be on. There are also doubts about whether to do it as the classic assistants that are only activated when we invoke them or allow it to act by yourself when you consider it useful. The big problem. Assuming that Altman is right and his gadget becomes a global success, the most serious problem they face is that OpenAi does not have the necessary computing power to operate its models on a massive use device, and that costs money (something that OpenAi is not left over precisely). In the case of Alexa or the Google, Amazon and Google assistant they have plenty of computing to make them work without depending on anyone else. OpenAi has chatgpt, The most popular chatbot in the worldand need to work with external investments. First it was his Alliance with Microsoftafter SoftBank’s investment, according to Nvidia And the newly announced according to AMD. If the gadget they want to launch ends up being massive as Altman wants, the numbers do not come out. The device. We do not know what you will call or what design will you have. The details that Altman and Ive gave in their day were quite lazyIn fact, they focused more on saying what it will not be than what will be. It will be similar to the mobile, but it will not be a mobile. Nor will it have a screen, but we will communicate with him through cameras, microphones and speakers. And they will not be glasses either. Nothing concrete, but for the moment it reminds a lot of Ai pin of Humane, that He failed loudly. OpenAi goes for hardware. OpenAI enters $ 1,000 million per monthbut the speed to which money burns is much higher than the one that enters it and would need to enter ten times more to be profitable. Even so, the company is already valued in half a billion dollars. Entry into the hardware business makes sense as a way of justifying its value. Beyond the doubts that arise around this mysterious device (They are many), Openai is very serious about creating a hardware division. When buying the IVE startup, they added 20 employees and later They hired several Apple experts and also of the finish team in charge of the target Quest and smart glasses. We will have to keep waiting to see if it ends up materializing in In Xataka | Data centers for AI are an energy hole. Jeff Bezos’s solution: Build them in space
