There are thousands of people hooked to streaming. One to 3,900 kilometers deep full of marine curiosities (and memes)

by

In the Submarine Canyon of the Sea of La Plata, near Argentina, something of the most curious happens: two powerful currents coincide. One is salty and warm. The other, cold and very rich in nutrients. The union of both is the Confluence Brazil-Malvinas And it is important in the Earth’s climate regulation. It is known that there is a huge ecosystem down there, one of which little is known and that, at the moment, it is being explored live by an underwater rov next to thousands of people who, since July 23, They follow their live emissions Through YouTube. The mission. These submarine cannons hide a varied species ecosystem in their recesses. In 2012 and 2013, the Continental I, II and III of CONICET expeditions (National Council for Scientific and Technical Research of Argentina) used fishing and drag networks to explore the bed, discovering new species and leading to the publication of more than 60 Papers. Now, in 2025, technology has improved and It is possible to explore depths up to 3,900 meters with a vehicle operated remotely. Continental slope IV: Underwater Oases of Mar del Plata Canyon. That is the name of this new mission, an expedition of CONICET in collaboration with the Schmidt Ocean Institute. As explained from the Council, “it is the first time that in the Argentine Aguas of the Southwestern Atlantic the remotely operated vehicle (Rov) is used, capable of capturing underwater images in ultra high definition and collecting samples without altering the environment.” The funny thing is that the adventures of this rov They are broadcast live through YouTube. The goal. In addition to studying the Argentine seabed as it has not been possible to generate 3D models of emblematic species to produce educational material. The one who has interest can access the data collected completely free through open repositories such as CONICET Digital, Bish and Genbank. Image | CONICET How is the thing going? According to Explain The CONICET researcher in the MACN and scientific chief of the expedition, Daniel Lauretta, “we are barely starting and we see incredible things: animals that had never registered in this area, underwater landscapes that seem from another planet, and behaviors that surprise even the most experienced scientists.” It also states that being able to broadcast it live makes “science is somewhat distant or inaccessible, and becomes part of the day to day. In addition, it forces us to explain what we do clearly, without turns, so that anyone can understand and enjoy it.” The memes. That streaming has become so popular, has undoubtedly helped the collective ingenuity when seeing comedy in the seabed. It is an unknown territory for most and the species that live there are striking. That is why it is not surprising that networks like X have been filled with captures, memes and funny texts with these species as protagonists. The capture of that sea star has gone around the world, but it is not the only one. As for whatever, users have baptized it as “Estrella Culona” | Image: Xataka Argentina Caught in fraganti | Image: Xataka Argentina A violet benthodytes. His nickname: Batatita | Image: Xataka Argentina “Me and the boys together to see a stream of the CONICET,” says an X user | Image: @Genaro23101 Jokes apart, why there? The Malvinas current moves north from Antarctica to almost Río de la Plata, dragging cold and nutrient rich from Antarctica to the Patagonian platform. This current is very important for Argentina and its fishing industry, valued at 2,000 million dollars According to Schmidt Ocean Institute. The current of Brazil, more superficial (700 meters or less), transports warm and salted water from Ecuador to Rio de la Plata. Where both currents collide a strong thermoclin that, in turn, and due to temperature differences, generates rotating currents that redistribute heat, helping to regulate the climate of the earth. As explained by the institute, “the mixture of these two mass of water so different probably creates conditions that facilitate the coexistence of temperate and tropical organisms, as well as species that can only be found in the confluence.” Hence this area has so much scientific interest.

An advanced marine drone with hydroalas that will patrol without crew

by

Thousands of kilometers of coastline, a large number of strategic trade routes and a sea where threats are no longer announced with ships, but with drones, sabotages and undercover operations. Europe has begun to rearmbut not only with fighters or frigates: also with light, autonomous systems and designed to act where the radars do not arrive. Arrow is one of them. And he wants to become the new sentinel of the sea. A European system for an increasingly hostile environment. Suicide drones cross the red sea. Corted submarine cablesBlocked GPS, Sabotajes without signature. The war has entered the sea, but it has done so in silence. Europe has understood: large ships are no longer enough. Discrete surveillance is needed, agile systems, technology that detects before it is late. What is Arrow and what makes it different. Imagine a ship that does not need a pilot, which barely generates noise and that could, in the near future, travel 740 km of coast without reposting. Imagine that, in addition, it is fast, stealthy and capable of acting autonomously. That is the Vision Arrow. The project, officially launched in July 2025seeks to develop a 12 meter European naval drone with hydroalas, capable of operating autonomously or manned. It is still in the design and planning phase, with a prototype planned around 2027 and validation between that year and 2028. The idea is that it reaches up to 45 speed knots, minimize fuel consumption by 50% and reduce the acoustic and visual trail. Its final purpose is not to face great threats, but to detect what others do not see and alert in advance. Arrow does not replace a patrol or a satellite. It aims to complement existing capabilities with an agile platform that combines discretion, artificial intelligence and operational efficiency: a tool designed to anticipate, not to attack. What will Arrow be and what makes it possible. The first thing that attracts attention is its form: elongated, stylized, designed to cut the water without generating noise or turbulence. Arrow does not float: Plan on the sea thanks to a retractable hydroalas system that allows you to reach up to 45 knots (about 83 kilometers per hour) and reduce consumption by half. A system that does not need a pilot. What differentiates Arrow from a conventional unmanned boat is not only its speed or its design, but its brain. It is expected to incorporate autonomous navigation systems with embarked intelligence capable of processing data in real time. That will allow you to detect obstacles, adjust routes, dodge interference and maintain communications without constantly depending on a human operator. This autonomy is key to acting in difficult or degraded environments, where the GPS signal can fail, be exposed to hackeos like those suffering from airplanes or the response time must be immediate. Instead of reacting from Earth, Arrow will make decisions in the water. Who is behind the Arrow Project. The Arrow project is managed by the European Defense Agency and has an estimated total cost of 10.7 million euros, of which The European Union will contribute almost 8 million through the European Defense Fund. The French company Seair coordinates a European consortium composed of ten organizations from eight member states or countries associated with the EU. The consortium groups eight technological SMEs and two research organizations, among which are: Seair (France) Maritime Robotics (Norway) D3 Applied Technologies (Spain) Knierim Yachtbau (Germany) Sierra Tango (Belgium) Maxwell Applied Tech (Spain) C & V Defense (Belgium) EU3Star BV (Netherlands) Taltech – Tallinn University of Technology (Estonia) Riga Technical University (Latvia) The objective: unite industrial and scientific capacities to create a European, autonomous and exportable solution. Arrow is not an isolated case: it is part of something bigger. The development of Arrow does not respond only to a technical need. It is part of a strategic turn: the European Union wants to have its own tools to defend their interests without depending on the pentagon. He is doing it with fighters (FCAS)with satellites (Iris2), with air defense systems (Sky Shield), and now also with naval drones like this. What is expected now. What today is a project on paper, within approximately three years could patrol the coasts of Europe. That is the plan. Arrow will have about 34 months of development ahead to move from design to reality. Throughout that time, the consortium must close the technical architecture, build a functional prototype and submit it to tests in real conditions. As we say, the first great milestone will arrive in 2027, with the demonstrations in the open sea. If everything progresses as planned, the system could be ready for real operations in 2028. At the moment no official images of Arrow’s final design have been disseminated. However, during the presentation of the project, the Naval News News He had access to a physical model and was able to take several photographs of the actincluding a partial image of the exposed model. These snapshots allow a first idea of the general lines of the system, although they still do not reflect their definitive configuration. The cover image is a creation generated with AI. It does not correspond to any official model, technical prototype or approved design of the Arrow system.

The big problem of marine wind is cables. Germany has a plan to avoid them

by

In the middle of the North Sea, an anchored barge off the German coast does not transport merchandise produces fuel. It is not science fiction: it is the first floating floor that converts wind, seawater and air into energy for the future. Short. In the port of Bremerhaven, Germany floats a rare platform. At first glance it looks like another industrial barge, but in reality it is a floating laboratory that prepares for something unpublished: to manufacture synthetic fuels directly in the sea. More in depth. The project His name is PTX-Wind and is part of the national H2Mare initiative, focused on the production of clean energy on the high seas. It is promoted by the Institute of Technology of Karlsruhe (Kit), together with the German Aerospace Center (DLR) and the Technical University of Berlin. The installation has not yet left the port, but it is already ready for its next phase: operating in real conditions against Helgoland. The purpose of the kit with this test is clear: show that e-combustible in the high seas can be generated, without electricity or land infrastructure. No cables, network or land firm. One of the most striking things of this platform is that it is not connected to any electricity grid. It works totally autonomously, using only wind energy, seawater and the surrounding air. What you get from there transforms it into liquid fuels ready to use, without net emissions of CO₂. According to Professor Roland Dittmeyer, director of the Institute of Microprocess Engineering of the Kit and project coordinator, this installation not only seeks to demonstrate the technical viability of the system, but also learn to climb it for future large industrial platforms. The heart of the barge. Inside, this platform integrates several advanced technologies that, together, form a Power -to-X (PTX) chain (PTX). In other words, they convert renewable electricity into fuels or other chemicals. The giant laboratory has a first phase of Direct air capture (DAC)which extracts carbon dioxide directly from the atmosphere. After that, desalination to transform seawater into water suitable for electrolysis. That water is divided into hydrogen and oxygen using electrolysis fed by wind energy. Finally, a synthesis is used Fischer-Tropsch to combine hydrogen with CO₂ and generate liquid hydrocarbons, also known as e-combustible. The entire system has been designed to operate in a modular, flexible and disconnected way of the electricity grid, adapting to the natural intermittency of the wind. This allows maintaining active production even in variable conditions, a key aspect for its replication at an industrial scale. First in your class? While there are other hydrogen production projects on land or offshore wind platforms, none until now had gathered all these pieces in a single floating and autonomous structure. According to Interesting Engineeringthis is the first plant that converts marine renewable energy into liquid fuel without depending on the mainland or electrical networks. The point is that not everything can plug. Today, many sectors already advance towards electrification: cars, heating, even some trains. But there are industries – as aviation, maritime transport or heavy chemistry – that still depend on liquid fuels with high energy density. The e-fuels, like those produced by this platform, They are a neutral alternative in carbon that could replace diesel or kerosene without the need to completely redesign airplanes or ships. And the best: they do not compete for agricultural lands nor consume fresh water. When operating directly in the sea, they take advantage of the wind potential and avoid costly terrestrial infrastructure. According to the Federal Ministry of Investigation of Germany (BMBF)also helps relieve pressure on local electrical networks. Not only diesel. Although for now the main objective is liquid fuels, the team behind PTX-Wind is also investigating other possible production routes, such as Synthetic methane (compatible with current gas networks), The green methanol (useful for maritime transport or chemical industry) and renewable ammonia (It works as a hydrogen bearer or as fertilizer without emissions). The sea as a new energy border. More than a prototype, the PTX-Wind platform represents a scalable and adaptable model for the production of fuels in the high seas. Its modular design would allow to replicate this technology in different coastal areas of the world, creating a distributed network of floating refineries of clean energy. At a time when climatic solutions are urgent and promises often stay on paper, this floating barge is a tangible example that innovation is already out there, literally floating in the sea.

Spain wants to reduce marine pollution and will start in an unsuspected place: the bathroom

by

Spain adds this year 642 beaches with blue flag, four more than last year, According to the Association of Environmental and Consumer Education (Adeac). This badge, which recognizes the environmental quality, security and services of the coast, returns to place the country among world leaders. Even so, the figure represents only 18 % of the more than 3,500 beaches in the country, which shows a pending challenge. To face it, Spain has begun to move. A new plan is brewing. Rather, a new bill with The goal of reducing pollution For single -use plastics, where wet wipe manufacturers will be forced to assume cleaning costs derived from the improper use of these products. In addition, the initiative wants to prohibit citizens from discarding wipes by the toilet and release balloons in the air. With this measure, Spain seeks to align with European standards on single -use plastics and move towards the UN sustainable development objectives. A serious problem. Wet wipes, even those made of natural polymers without chemical modifications, generate an important environmental impact. Its resistance to decomposition causes obstructions in sewerage and purification systems, especially during periods of heavy rains, such as has detailed The Guardian. The microfibers that release reach rivers and seas, aggravating pollution and raising management costs for local authorities. Responsibility. The new law will force companies to take care not only for the cleaning of the waste they generate, but also of information campaigns. To control who should pay, manufacturers will have to officially register. Although biodegradable wipes would be exempt, the Ministry of Environment He has insisted In that it is best not to throw any for the wiper, to protect pipes and the environment. A very economical topic. A awareness campaign of the Spanish Water and Sanitation Supply Association I already estimated Six years ago, the withdrawal of these wipes was an annual cost of 230 million euros. Until now, economic consequences have fallen to public administrations. According to eldiario.esValencia had to invest 10 million euros in 2019 to clean a three -kilometer jam. In Badajoz, a similar athlete was a cost of 200,000 euros. Murcia encrypted in more than 250,000 euros the replacement of a damaged team at a treatment plant, while the repair of pumping equipment amounted to another 200,000 euros. Other countries already have the lead. Four years ago, both France, Germany, Belgium and England They prohibited use of single -use plastic products, following the EU guidelines. In addition, on the one hand, France a year later prohibited the use of plastic To package small fruits and vegetables. On the other hand, Germany and Belgium They have been developing A fund funded by single -use plastics manufacturers, who must contribute according to the amount of plastic they sell. This fund aims to cover the cleaning costs of public spaces and waste management, reinforcing the principle of “who pollutes, pays”. It does not start on the shore. While the bill continues its parliamentary processing, its effectiveness will depend much on the citizen response. Because the care of the beaches does not begin only on the coast, but in the daily habits of those who enjoy them.

Authorities reported that A 24 -year -old sergeant died after being injured in a ski accident in a popular tourist center of Coloradowhile visiting his family during the holidays. Jessie Mello, 24, was skiing in Powderhorn Mountain on December 24 when he suffered a serious head injury and bone fractures, confirmed the forensic table county and the complex to Fox News Digital. The authorities said The young woman was on an intermediate level path when the accident occurred on Christmas Eve. His father, Eric Mello, told The Colorado Sun that the eye witnesses reported that the woman crashed into an ice plate and a tree. He wore a helmet at the time of the accident. After the accident, the skiing patrol responded and transferred it by plane to the St. Mary’s hospital in Grand Junction, Colorado, about 40 miles from the complex, where they placed it in intensive care. The table of table county said that Mello remained hospitalized for several days, but died on January 5 for head injuries. “My girl fell in peace in Jesus’ arms tonight,” his father, Eric, wrote in a Facebook publication. Mello’s funeral was held at the Lutheran Church Messiah on January 10. He remembered as a “woman of incredible talent, character and love.” Continue reading: –18 -year -old dies in a ski accident in popular Tahoe area, Nevada–An skier died and another was injured in a large avalanche west of Wyoming–12 -year -old boy dies in a ski accident in a New Hampshire mountain (Tagstotranslate) Colorado
