China is immersed in a nuclear revolution and needs industrial amounts of Uranium. His solution: “fish” in the sea

May 10, 2025 by usatoday24

China is one of the countries that is most promoting the adoption of renewable energy thanks to Great ‘farms’ and market saturation of solar panels. At the same time, they have approved the Construction of ten new nuclear reactors. It may seem a contradiction, but in the midst of a Strong commercial warit is another step in energy self -sufficiency, and to achieve it they will need tons of uranium. Your solution? Squeeze the uranium of the seas. Marine mine. The country account with 56 nuclear reactors and has between 25 and 29 under construction. This implies that they need a lot of Uranium and the problem is that they do not produce enough. HE esteem That, in 2023, China’s production was only 1,700 tons, 4% worldwide, and although they have strong reserves, they need more. In turn, China imported Some 22,000 tons in 2024 and have begun to put solutions. In 2024 began The construction of the National Project of Uranium Nº1 in Ordos. It will become the largest uranium mine in the country and a few months ago They announced that had discovered another important site, also in Ordos. However, it still is not enough, so they have seen the sea. Uranium fish. Because yes: there is uranium in the oceans. Its concentration is extremely low, about 3 micrograms per liter, but due to oceanic immensity, it is estimated that the total is 4.5 billion tons of uranium. There are a thousand times more uranium in the seas than in known land reserves. Extract Uranium from the sea is not something new and, during the 80s, Japan led the development of marine uranium extraction techniques. The problem is that it is a complex and, above all, inefficient process. That is why researchers focus on active uranium collection methods‘dapando’ different materials to be able to extract more material per liter. It is also a expensive method, about ten times more to extract it from terrestrial sources. Miraculous material. But this is where the Chinese team of the Frontiers Science Center For Rare isotopes of the University of Lanzhou enters. In a study published in NatureThey explain that the key to extracting more efficient marine uranium resides in the MOF, or metal-organic frameworks. It is a crystalline material composed of metal ions that are coordinated with organic elements to form structures of great porosity. It is like an extremely efficient fishing network to catch small particles that, in the case of uranium, allows you to better separate this element from others to which it can be attached. The Chinese team has dopa with Dipniletinelo molecules and claim that this new DAE-MOF material allows an uranium absorption capacity of 588 mg per gram, according to the tests. This involves an efficiency 40 times higher when separating uranium from metals and vanadium and has been tested both in simulated and real sea water. Aim. The idea is now to create test extraction plants this year, with pilot plants on the tons scale for 2035 and with a continuous production by 2050. wait That China’s demand for uranium is more than 40,000 tons in 2040, so land mines in conjunction with these marine alternative sources are essential to achieve the goal. Without a doubt, it is an advance in marine uranium extraction at a time when the rest of the players on this board are also found Looking for ways to get more out of the sea for energy independence at a time when buying to other countries He has put up legs. And the United States, of course, is also in that fight, with the US Department of Energy analyzing The technical, economic and environmental viability of large -scale uranium extraction in its waters.

We take more and more mercury through fish. There are those who want to solve it with “design” probiotics

May 5, 2025 by usatoday24

The presence of mercury in fish (or in some fish) is A growing problem in the field of food security. Prolonged exposure to this pollutant is an important risk to people’s health, a risk that could go worse in the coming years. Detox, but real. A team of researchers has manipulated a bacterium present in the digestive system of humans to do it Able to eliminate methylmercury present in fish. In a study with mice, the mechanism allowed this toxin to reach other organs of the animal, such as brain or liver. An increasing problem. He methylmercury It is a cation, a molecule with a positive charge, which gives its name to a series of compounds that integrate this form of mercury. Methylmercurio is also the most common way in which we can find organic mercury naturally. Mercury in its different forms is a pollutant present not only in some pesticides but also in Gas emissions to the atmosphere. These mercury residues end up arriving at the sea and the trophic chain, a process called “biomagnification.” This heavy metal tends to accumulate more in larger fish and in those closest to the cusp of the “food pyramid.” And from there, to our kitchens. Design bacteria. The work It started from a known bacterium and abundant in our digestive system, Thetaiotaomicron bacteroids. It inserted coding DNA enzymes from another known bacterium present in the soil, a bacterium with a determining feature, its resistance to mercury. Probiotics The team first checked In vitro that these bacteria had managed to become resistant to methylmercury, and then administer bacteria to mice. These soon were integrated into the digestive system of mammals, which was administered orally to study the impact. The team first analyzed the effect of The administration of a large amount of this compound. They found that in the mice to whom the new bacterium had been administered, the mercury began to disappear shortly after its administration, a purification process that lasted for about four days. In the long term. The team also studied the effects of moderate but prolonged mercury consumption in time. The team altered the mice diet and made it rich in red tuna, one of the fish with higher heavy metal concentrations. Not only did they verify that the methylmercury continued to disappear from the digestive systems of the mice, they also verified that it did not permeate the body of these. The team studied the effect on pregnant mice, checking that methylmercury levels were kept low in maternal and fetal tissues, including less toxicity in the fetus’s brain. The details of the study were published In an article In the magazine Cell Host & Microbe. A problem that will go worse before better. The study opens the way to the use of “design” probiotics that could help us avoid the worst consequences of mercury pollution. This method does not attack the root problem but, as their own creators explain, it can help us address a problem without a short -term solution. “Despite global efforts to reduce mercury emissions and their accumulation in fish, metercurio levels are not expected stood out in a press release Amina Schartup, co -author of the study.

A Japanese restaurant has brought its obsession with fresh fish to the extreme: it allows you to fish yourself

March 8, 2025 by usatoday24

Visiting Japan is immersing yourself in a country where the traditional and modern coexist in harmony. Its big cities combine futuristic skyscrapers and streets full of neon lights with millenary temples that have resisted the passage of time. In any walk through its streets, it is inevitable to find restaurants where fish is the absolute protagonist. And it’s no accident: in Japan, Fish has been a pillar of its gastronomy for centuries. Here, the menu is not requested, fishing. If you think you’ve seen everything about freshness, Japan always has more to offer. There are restaurants where chefs personally select the best fish on the market every day, but what if instead of waiting for them to serve you, is you who fish it? In Osaka, about five hours from the center of Tokyo, there is a place where the menu is not chosen, it is captured at the time. Our protagonist bears the name of “ジャンボ釣船つり吉”, which could be translated into Spanish as “Great Tsurikichi fishing ship.” As we can see in Google Maps screen capture, it is far from the bustle of the great avenues of the Asian city, and is immediately distinguished by its facade decorated with a fishing boat and posters with large Japanese characters that tell us what we will find inside. As explained on your websitewhen crossing the restaurant door the first thing will be to check the letter and choose the fish we want. Once decided, the staff will give us the right equipment, be it a fishing cane or a salabre, and will guide us to the fishing area. In that pond, where fish swim outside of their destiny, true experience begins. They assure that it is an apt challenge for all ages. After fishing, it is time to enjoy food in one of the four rooms available. We can choose between Tatami type seats in a ship -shaped area or, if we prefer something more conventional, tables with western -style chairs. Now, suppose we are ready to live this experience. How much will it cost us? It is time to take a look at the letter and calculate the budget. How much does this experience cost? When planning the expense, the first thing we should consider is that the price is based on the entire fish that we catch. Thus, a red kissing costs 3,124 yen (about 19.50 euros), a sole has a price of 2,840 yen (approximately 18 euros) and a listing juris rises to 4,980 yen (around 31 euros). Once the piece fish, we must choose how we want to prepare it to us, which is an additional cost. For example, a frying with Ponzu adds 300 yen (about 1.90 euros) to the final price. In addition, if we want to accompany our dish with seafood, we must take into account that they do not have a fixed price. In this case, the staff will weigh and inform us of the cost before preparing them. Marketing, Tourism and Gastronomy. It is no secret that Japanese gastronomy is rich and diverse, with fish and rice as fundamental pillars for centuries. However, many of the dishes that we consider today representative of Japan, and that have crossed borders, are not the result of a centenary tradition, but of relatively recent adaptations. Without going any further, until the 1990s, no one in Japan ate sushi with raw salmon. It was a marketing campaign that made it a standard, more than an entrenched custom. But tourists continue to come in mass in Japan in search of a unique experience. And there is no doubt that the country has much to offer, especially in the gastronomic field. However, not everything is good news, neither for the premises nor for those who visit it. An ingredient as essential as rice suffered a remarkable crisis: in full tourist boom, The shortage shot prices and led some restaurants to pay anything to stock up. When what matters is the show. Eating typical dishes in Japan has its charm, but restaurants have found ways to go further, especially when the goal is to attract tourists willing to spend on experiences. The possibility of fishing your own food in a place set as a ship is not only a gastronomic option, but a claim designed to turn dinner into a show that seduces both visitors and premises. {“Videid”: “X8D7XNV”, “Autoplay”: False, “Title”: “Tricks to travel cheaper- Drinking tea is something that can be done anywhere in the world, But attending a tea ceremony is another story. In Japan, this ritual has become an attraction for tourists looking for more than a simple infusion. The experience is not limited to drinking tea, but extends for hours, with different varieties and meals included. Something that originally had a deep cultural significance is now also sold as an experience for the visitor wanting to spend. But the show does not end there. If tea is not enough, there are always more options to live Japan in a big way: geisha shows perfectly choreographed for the tourist, high exhibitions where tradition and show intermingle, and the Bunraku puppet theater, a cultural element that continues to find its place in a country where more and more things become attractions for the photo. A HAND FOR MOUNT FUJI. To promote other forms of tourism in Japan could be one of the keys to decongest Mount Fuji, a place that for centuries was a symbol of spirituality and personal improvement, but today dealt with massification and its consequences. What was previously an intimate journey has become a crowded tour of hikers, with tails on the top and an environment that is increasingly feeling the weight of uncontrolled tourism. In Xataka Japan has put a spicy in Spain in a peculiar way: with a "Madrid Osaka" In a town of 93 inhabitants To mitigate the impact, The government has begun to take action: daily visitor limits have been established and an online reservation system has been … Read more
