Apple Watch technology in headphones. Measuring heart rate is no longer just a clock

Apple bought Beats Music and Beats Electronics in 2014 and, although the AirPods are still the most recognizable headphones of the company, the development of Beats has not stopped since then. The Powerbeats pro 2 They are the new beatic headphones and, in addition to respecting the hook format that works so much in the sports market, these are the first headphones under the Apple umbrella that land with A curious function: heart rhythm monitoring. These headphones, at a technical level, arrive with cancellation of active noise, adaptive equalization, space audio, Apple H2 chip and total compatibility with Apple devices (hands -free with Siri, network search, link with a single touch, etc.) They promise an autonomy of up to 10 hours Of continuous reproduction, they work with Qi wireless loaders and are resistant to both sweat and water. What is expected of beats that are launched at a price of 299.95 euros. What does a cardiac monitoring sensor paint in headphones Made the presentations, the clear doubt comes in its key specification. These powerbeats are capable of Measure our frequency in real time. They become the first Beats product to incorporate this monitoring. But how do they work in headphones? According to Beats, a lot of development has been invested to design and locate these control sensors. In this case, They are located right next to the padand make green light more than 100 times per second. The company details that the years of research in heart rate control of Apple Watch have been used to continue this development in the headphones, reducing technical architecture to 1/16 of its original size to integrate it into a headset, without compromising comfort or precision. Beyond marketing, Apple has trimmed Apple Watch sensors to implement them in these headphones. And, yes, they will only work if you have both positions. The goal is to offer an alternative to the smart watch, so that athletes can measure their heart rate while wearing headphones. They are a solution for those fashionable sports, such as Crossfit or Hyrox, in which it is not possible to train with a clock placed. Headphones as a health complement Apple has not been the first to introduce heart rhythm sensors into headphones. Amazfit got it in 2020 with its Powerbudssome headphones of less than 100 euros, and Anker sells his Soundcore with a “similar” technology. The quoted is mandatory because, to date, Apple Watch heart rate measurement is one of the most reliable proposals. If Beats has managed to take this technology to its headphones, at least on paper, They should lead this land. Beyond this particular case, these headphones They will be an excellent thermometer. They can be the door that, in the near future, Apple Airpods incorporate heart rhythm sensor. A movement that would make enough sense, seen the clear health approach that the company’s products have.

Venice invented an entry rate to stop mass tourism. It has come out so well that it will double the price

Tourism is equal to massification in Venice. It is nothing new and, in fact, the enclave has been a pioneer in some regulations that have sought to put the hordes to combine the life of the premises and that their ecosystem does not end up engulfed victim of their own success. His geography simply does not give for more, and that’s why they have imposed Bumpers to large groups with fines Whoever passes, or even They have tracked phones. They also imposed A pioneering tollan entry rate that went so well that They doubled the days. Now also the price. The experiment is consolidated. As we said, Venice is a pioneer in the imposition of An entry rate for single -day visitorsand success has been such for the administration that They have decided to duplicate the rate in 2025, raising it from 5 to 10 euros for those who enter without accommodation reserve. In addition, and as we explained a few months ago, The measure will be applied in 54 days a year, almost twice the 29 days selected in 2024. The dates include a continuous block from April 18 to May 4, followed by every Friday, Saturdays and Sundays until the end of July. The collection will remain from 8:30 am to 4:00 pm, and those who reserve at least four days in advance may pay only 5 euros. What do politicians say. The Tourism Councilor, Simone Venturini, gave a track of the announced change. Apparently, at the Milan Bit fair, he said that the 2024 pilot project was so successful, achieving its goal of managing tourist flows and discouraging massive tourism of a single day, which they have decided to enhance it. In fact, International destinations such as Formentera in Spain either Kyoto in Japan They have shown interest in replicating the Venetian initiative. Impact on the tourist rate. In 2024, almost half a million tourists (485,062) paid the entry rate, that is, that They generated 2.4 million euros in revenue to public coffers (The cost of the system or the destination of the funds collected) has not been revealed. The registration data indicates that, after the Italians, the main tourists were Americans, Germans and French. In addition, the measure achieved a slight reduction in the number of visitors from the Véneto region, although the authorities have not given figures. We also remember that despite this tariff increase, access remains free for those who spend the night in the city, although They must register online in CDA.ve.it to obtain their exemption. Travelers who only transit Piazzale Rome, Tronchetto or Stazione Marittima, as well as those who visit the outer islands of the lagoon (Lido, Murano and Burano) without going through the center are also exempt. The future in Venice. It is the big question. The authorities admit that the rate alone is not enough to manage mass tourism, but they do consider that The created system feels the bases for future regulations stricter. Venice, that Receive tourists from 194 countriesremains one of the destinations most affected by tourist overexploitation, which has led to the implementation of increasingly restrictive measures in an effort to protect its fragile urban ecosystem and preserve its historical character. One more than difficult equation.

Europe has the highest rate of multiple sclerosis in the world. The explanation lies in the DNA of the steppe shepherds

First there were hunter-gatherers about 45,000 years ago. The first modern humans arrived in a Europe where the Neanderthals still reigned. Then there were the farmers of the Middle East about 11,000 years ago and finally, about 5,000 years ago they were the nomadic pastoralists of the steppes of Central Asia. That is, according to research published in the journal Naturethe common genetic heritage of Europeans. A heritage that explains why, in an incredible historical twist, multiple sclerosis affects us more. A DNA mutating in the middle of the great steppe. While agriculture gained weight in the world, the great Eurasian steppe continued doing its thing. The culture yamnaa group of pastoral towns that arose in the enormous plains south of the Urals and east of the Black Sea, generations and generations passed living with livestock. Variant. It was there that it emerged (and was selected) a small genetic variant that strengthened natural immunity against zoonoses; that is, against livestock infections that could easily jump to the human communities that raised them. 5,000 years later, this genetic variant is behind the fact that Europeans have a higher risk of suffering from Multiple Sclerosis. The deep origins of current diseases. The study led by the Universities of Cambridge and Copenhagen (but with the participation of many more) analyze in detail from the DNA of almost 5,000 individuals spread throughout history. Some studied remains date back to about 34,000 years ago. The reconstruction. Reconstructing humanity’s immense genetic tree, researchers found numerous keys to understanding why there are specific geographic areas or ethnic groups that suffer from some diseases more than others. They realized that southern Europeanswith a greater genetic legacy from the agricultural people of the Middle East, have a greater predisposition to develop bipolar disorders; that people from the East had a higher genetic risk of developing Alzheimer’s or diabetes; and those from the northwest had a heightened risk of sclerosis. A medical enigma. For years, scientists have tried to understand why Europe has, with about 143 cases per 100,000 inhabitants, one of the highest incidence rates of sclerosis in the world. As I said in the previous paragraph, as you go south and east those differences fade, but (even so) the greater risk of developing this disease It is a European ‘differential fact’. Understanding better. The most interesting thing about all this is that the idea that the answer lies in the genetic history of its inhabitants It is not only a historical curiosity. On the contrary, thinking about this from an evolutionary point of view allows us to understand the disease in a new way.
