His new “party” are working 92 hours

by

In Silicon Valley, the new generation of young entrepreneurs has left behind the parties at which alcohol rivers ran. The example that follows is that of the big names of Silicon Valley, such as Mark Zuckerberg, Elon Musk, Sam Altman or Bryan Johnsonwhich prioritize their business projects ahead of their own social life. The phenomenon is not isolated, and more and more young entrepreneurs share the same mentality: “Why go to a bar if I can be creating a company?” Summarizes Emily Yuan, a young founder of Silicon Valley, In an interview for The Wall Street Journal. The data does not lie: alcohol consumption Among the youth of generation Z It is being reduced and, in the scope of Silicon Valley startup incubators, the norm is increasingly and not exception. Silicon Valley’s new habits. The daily routine of those who aspire to success in Silicon Valley is marked by working hours that exceed the usual. According to what was published by The Wall Street JournalMarty Kausas, 28 years old and founder of the startup Pyloncommented in a LinkedIn publication that chained several weeks in a row of 92 hours of work and that canceled his vacation because the stress of work prevented him from taking A few days to rest. However, in Another publicationthe young entrepreneur ruled out that in his company a “culture of 996” was applied for his employees, in reference to the new Asia export trendin which you work from nine in the morning to nine in the afternoon and six days per week. What is fun? The main paradigm change that shows this group of very young technological entrepreneurs is to define What is fun. In his case, and as Marty Kausas and Emily Yuan detailed, what they consider fun is not to spend some time with friends drinking some beers. “Our motivation to start a company was fun and adventure. But what is fun for us is quite different from what is fun for others.” That concept, together with the messages against alcohol that are giving some influential figures of Silicon Valley, such as Sam Altman, which has manifested himself totally contrary to alcohol consumptionor Mark Zuckerberg that, Unlike your cowsjust drink beer on few special occasions and what is necessary To take the photo. In general, for “Tecnobros“From Silicon Valley alcohol and parties no longer enter the concept of fun. Sobriety in the tech era. Generation Z, globally, is reducing alcohol consumption worldwide. The data They point out that there was a drop in alcohol consumption of 4.5% per year since 2011, and has been stabilized since then. According to him last report of health the average consumption of each adult in Europe went from 12 liters per year in 2000 to 9.5 liters in 2019, and if we focus on wine, the only alcoholic beverage that drinks Jeff Bezos In special celebrationsthe Data point to that its average consumption per adult has fallen from 14.2 liters in 1990 to 10 liters in 2017. In the “new garitos” there is talk of financing This decrease in alcohol consumption has been associated with a cultural change in the social activities of these new entrepreneurs. The meetings between colleagues, formerly animated by toast and drinks, are now meetings in Saunas, motivational talks or gym routines in search of professional connections. Miranda Nover, co -founder of a fitness startup called Fort, said In an interview for Business Insider That the image of ascetic existence is very important for young entrepreneurs. “You are trying to transmit: we do this six days a week in the office, we work until 9 pm, we do not drink, we do not party, we do not do any of that.” The businessmen of the future are “Healthy”. Unlike what happened with the previous generations of Millionaire Founders, such as Henry Ford or Aristotle Onassis, in which alcohol ran to all its parties. Now, alcohol consumption has ceased to be the central axis and a closer philosophy has been adopted to the Millionaire’s postulates Bryan Johnsonto focus all the energy on productivity. In San Francisco’s artificial intelligence events, alcohol is absent. According to Michelle Fang, 26 years old and event organizer for these Precotes founders of Silicon Valley, among the reasons why at the parties of the Entrepreneurs quarry is not only for a Change in the concept of leisure And health: “Many events related to AI do not serve alcohol, not only because it is out of fashion among the San Francisco public. Many founders are not enough to drink.” In Xataka | Alcohol is no longer cool: the “arrogance curious” movement is turning the abstemious into a trend Image | Unspash (Nguyễn hiệp)

Anthropic says that Claude Sonnet 4.5 can clone a service like Slack in 30 hours. Reality is more complicated

by

Anthropic has launched Claude Sonnet 4.5 ensuring that they put it to work 30 hours in a row to build a Slack replica. During that time, it generated 11,000 lines of code without supervision and only stopped when completing the task. In May, its Opus 4 model managed to operate for seven hours. The company presents it as “the best model in the world for agents, programming and use of computers.” Why is it important. Anthropic, Openai and Google free a battle to dominate Autonomous agents and programming tools. Those who convince will capture a lot of money in business licenses. Scott White, product manager, says that “at the level of a cabinet chief”: coordinates agendas, analyzes data, writes reports … Dianne Penn says he uses it to search for candidates on LinkedIn and generate spreadsheets. Yes, but. The developers tell another more nuanced story. Miguel Ángel Durán, known as @Midudevsummarizes it: “Claude Sonnet 4.5 Refactor my entire project in a Prompt. 20 minutes thinking. 14 new files. 1,500 modified lines. Applied clean architecture. Nothing worked. But how beautiful it was. “ Other developers They report the same: thousands of lines with an impeccable structure, but do not execute. Code that seems professional but collapses when compiling it. Between the lines. Anthropic has not shown the application of Slack working. He has only said that he built it. Nor has it shown that the code is operational. The difference between communicating something and demonstrating it, Underlined by Ed Zitron. The company is indirectly recognizing the problem: Claude Sonnet 4.5 arrives with extra infrastructure to build agents – virtual management, memory management, context management, multiagente support …–. Translation: Even with the most advanced model, developers need extra tools for agents to program reliably. In detail. Penn He explained to The Verge that the improvements surprised the internal team. The model is three times more skilled using computers than the October version. The team spent the last month working with feedback of github and cursor. Canva, Beta-fieldsHe says he helps with “complex long context tasks.” The contrast. There is a huge gap between marketing and technical reality. Anthropic promises an AI that operates 30 hours building complex software. Developers confirm that it generates very well structured but functionally broken code. This pattern is repeated throughout the industry. The models improve generating code that seems professional. They systematically fail generating code that really works without important human intervention. And now what. The question is still unanswered: when will we pass from Which generates beautiful but diffunctional code What generates functional code alone? Anthropic bets that his combination of powerful model and extra infrastructure closes that gap. At the moment we must continue waiting for concrete evidence to arrive, do not give without verifiable code.

Chinese astronauts have spent six hours reinforcing tiangong against an increasingly dangerous enemy: space garbage

by

The night in orbit just leaves truce. In low orbit, the Tiangong Space Station It becomes the scene of a constant activity that requires millimeter precision. In the last extravehicular exitChinese astronauts had to face a challenge that does not come from technical failures or scientific experiments, but from a silent enemy that multiplies the risks of each mission: the Space garbage which accumulates in the low terrestrial orbit and threatens to hit the structure of the complex. The schedule of China’s manned flight agency places the start of extravehicular activity on September 25 at 19:45 (Beijing time), with Wang Jie as the first astronaut to leave the Wentian module. It was followed shortly after Chen Zhongrui, in charge of attending the installation of the equipment. Chen Dong, from inside Tiangong, managed communications with the control center and supported his teammates throughout the maneuver. The walk concluded at dawn, at 1:35 of September 26, when the two crew closed the hatch after completing the planned agenda. The maneuver was carried out with support from the robotic arm of the station and the team on land. Sludes against fragments: Tiangong’s strategy to resist in space During the walk, the main objective was to install a protection device against Orbital fragmentsdesigned to reinforce the most exposed areas of the station. The operation also included the review of the state of external equipment and structures, with special attention to the systems that suffer greater wear due to continuous exposure to the spatial environment. According to those responsible for the programthis combination of installation and maintenance seeks to ensure that Tiangong maintains its operational capacity in the middle of an increasingly saturated environment of remains. The increase in spatial garbage in the low orbit is one of the factors that most worries agencies in recent years. Each launch adds fragments that, although small, reach speeds that multiply their damage. For China, reinforcing Tiangong does not respond to a specific incident, but to the need to get ahead of an increasingly complex scenario. China is not the only one that has had to reinforce its station in the face of the threat of orbital fragments. The International Space Station Specific armor systems for years have beenknown as anti-mmod shields, which protect their habitable modules from impacts from Micrometeoritos and space garbage. The difference is in the context: it is an infrastructure with more than two decades of service, which has needed to adapt continuously to an increasingly congested environment. In the ISS, this philosophy materializes in shields in Whipple and Stupfed Whipple layers, with several hundred shields distributed in critical areas. The comparison between Tiangong and the International Space Station helps to understand the scope of its protection systems. The Chinese station completed its construction in 2022 with a T configuration formed by the Tianhe, Wentian and Mengtian modules. The ISS, on the other hand, began to assemble in 1998 and ended its main segment in 2011, with a much broader and more complex structure. This difference in dimensions and seniority explains why its shields follow different logics: ISS combines protections included from its design with reinforcements added over the years, while Tiangong integrates solutions designed from the beginning for a more congested environment. The closure of this extravehicular activity does not imply a break, but the beginning of a new stage for the Shenzhou-20 mission. The three astronauts They will continue with numerous scientific experiments and technological tests, in addition to participating in on -board celebrations linked to the Chinese calendar. The installation of additional shields has a clear objective: to hold over time the crew safety and the integrity of Tiangong, which aspires to consolidate as a stable basis for space research in the midst of a more demanding orbital environment.

In 48 hours the Gaza conflict will take a 360 degree turn. And some options were science fiction just a few days ago

by

Trump, accompanied by Netanyahu, has presented An ambitious plan of peace that seeks to end almost two years of war in Gaza, releasing Israeli hostages and opening a reconstruction process under international supervision. Its scheme demands the surrender of Hamas, the total disarmament and its political exclusion, offering in return the release of about 2,000 Palestinian prisoners and the massive entry of humanitarian aid. TO Your ultimatum He has hours left for the conflict of a 360 degree turn. An unexpected plan. Unlike previous proposals that were limited to partial truces, the one now intends a definitive cessation of hostilities, with a period of just 72 hours (now about 48) so that Hamas delivers all captives. Israel would keep troops in A safety corridor Within Gaza and in damping areas, but it would commit to partial replication, while a Palestinian Technical Committee Under the tutelage of A “Board of Peace” chaired by Trump and with Tony Blair in a prominent role. The project, prepared in consultations with Israel, Qatar, Egypt, Saudi Arabia and the United Arab Emirates, has been qualified by the White House as the most realistic route to close the war and redraw the future of the strip. The concessions to Netanyahu. Netanyahu achieved, to a large extent, Impose your conditions: Hamas would be out of any future administration, the Palestinian authority would only have a hypothetical role subject to drastic reforms, and the creation of a Palestinian state would be deferred to an indefinite horizon. If you want, for the Israeli prime minister, internationally cornered after European recognitions of a Palestinian State and after the Boicot in the United Nationsit was a kind of Rare Diplomatic Victoria: together with Trump he was able to show that he still controls the times and that Washington supports his “total victory” strategy. The right. However, this same position opens cracks within Israel, where the radical right accuses the government of Claudicar by accepting a plan with Symbolic concessions to the Palestinian cause and with the introduction of foreign forces in Gaza. Smotrich and Ben-Gvir They have warned that could demolish the coalition if the agreement becomes a definitive peace that freezes the military offensive, which predicts political turbulence that Netanyahu tries to dodge with procedure maneuvers, such as avoiding taking the entire plan to the vote of the security cabinet. The pressure on Hamas. For Hamas, The proposal is lethal In political terms: he would mean the end of his domain in Gaza after almost two decades, the disarmament of his brigades and the delivery of his last hostages without guarantees of future influence. Even so, the group faces an unpublished pressure: Türkiye, Qatar and Egypt have expressed support for the plan and warn that Hamas’s time runs out. Many analysts They point that the direction of the militia seeks a “decent landing” that saves part of its paintings and avoid total annihilation, but any acceptance of the agreement would mean cross the red lines He has always proclaimed, especially the maintenance of his armed arm. In that context, Trump launched that public ultimatum: “Three or four days” to answer, accompanied by the threat that Hamas will “pay in hell” if he rejects the offer. The dilemma for Islamist leaders is clear: giving and surviving politically in exile or resisting and risking that Israel resumes an even more devastating offensive. The Arab mediators. In this case, Arab countries have gone from rhetoric to direct involvement. Saudi Arabia, Emirates, Egypt, Jordan and Qatar have transmitted to Washington and Israel A list of conditions: No to the annexation of Gaza, not to the forced displacement of Palestinians, not to new settlements, and yes to a horizon of Palestinian self -determination. Although Trump’s plan does not fully satisfy these demands, he has incorporated concessions as the mention of a possible “credible route towards Palestinian self -determination” if the Palestinian authority undertakes reforms. The paradox is that the authority itself, weakened and discredited, has Backed the plan With enthusiasm, accepting to review your textbooks, eliminate payments to prisoners and open to international scrutiny in order not to be excluded. For Arab states, the priority is close the war frontcontain humanitarian drift and keep the prospects for the solution of two states alive, even in a rhetorical framework. Internal risks in Israel. We said it before, the agreement threatens to fracture The Israeli coalition. While the centrist opposition supports him as a realistic basis to recover hostages and stop the war, the ultra -nationalist parties perceive it as an inadmissible assignment. The fear of Smotrich and Ben-Gvir is that to accept international forces and a Palestinian administration, even if it is technocratic, EROSIONE ISRAELI CONTROL and leave the door open to a future Palestinian state. Netanyahu tries to keep the Delicate balance: Present the agreement as a triumph in Washington and before the international community, but reassuring its right -wing base ensuring that Israel will retain military presence in Gaza and will never allow a sovereign Palestinian state. This double discourse reflects the fragility of your government, increasingly dependent on maintaining the security narrative against external demands. Trump’s disappointment. The change in tone of Trump himself to Israel does not cease to be striking. In private And in recent statements, the US president has shown An unusual anger with Netanyahu for unilateral attacks that have put the mediation of Washington, such as the bombardment in Doha against Hamas leaders when a fire was discussed. Trump se Feel disappointed So consider a lack of reciprocity: while he has sustained Israel in the international arena, Netanyahu has acted so that weakens the strategy North American diplomatic. This disenchantment, also applicable To the “Russian friend” In the Ukraine War, explains the Plan turnwhich is no longer just a blank check for Israel, but a frame with commitments and deadlines, in which it is even mentioned, even if it is vaguely, the perspective of a Palestinian state.

When a mine turned off all its coal fueled engines, it continued to operate 84 hours thanks to something: the renewables

by

For 84 hours in a row, a remote gold mine in Australia He completely turned off Its gas and diesel engines and worked only with wind, sun and batteries. It is not a laboratory experiment, but a real underground operation. History comes in a golden context – it never just said. “Gold Historical records brand Above 3,600 dollars an ounce, promoted by the search for refuge in the face of geopolitical and monetary uncertainty. This climbing and the renewed appetite for the bullion become a backdrop of the “clean gold” story. Turning off the past. The Bellevue underground mine, in Western Australia, affirms than the installation Off-Grid 84 consecutive hours worked in August with the “off engine” – that is, without thermal generation -, demonstrating that 100% renewable is possible for remote industries. A great infrastructure. The milestone has been possible Thanks to the remarkable installation which contains: 24 MW of wind energy distributed in four wind turbines, 27 MW of in situ photovoltaic plot and a 15 MW/30 MWh storage system. The support is made up of 9 MW of diesel and 15 MW of gas, which act as support when the renewable resource or battery does not cover the demand. Zenith Energy, the company that operates the plant under a long -term energy purchase agreement, details that the hybrid micorred It reaches about 90 MW installed, with synchronous capacitors and a micorred controller designed so that the mine can completely disconnect from fossil fuels at times of greater renewable generation. A meteoric progression. The ascending curve is clear: in July 2024, renewable participation was only 14%. In June of this year he had already climbed to 64%, in July to 78%and in August he reached 88%, According to Reneweconomy. Since the start -up of wind turbines between May and June 2025, the mine It has operated regularly With more than 90% renewable energies for full days of 24 hours, with several days at 100%. It is not an isolated episode. In June 2025, shortly after the entry into operation of wind turbines, the mine managed to operate 58 hours in a row, renewable 100%, According to Stockhead. In this way, both milestones reinforce the idea that using renewable is technically viable even in energy intensive industries and isolated from the network. A new market: Green Oro. Bellevue is trying to sell part of its production with a premium through the ABC Refinery refinery and the Single Mine Origin program, aimed at jewelry buyers and central banks with ESG sensitivity. “Bellevue states that he now produces and sells ‘green gold’ after reaching the goal of zero net emissions,” They detail in stockhead. In addition, it includes smart ventilation systems on demand (VOD) that reduce electricity consumption up to 30 %, and tests with underground electrical machinery. The nuances. The “net zero” label cannot be taken lightly. The status was reached in scope 1 and 2, that is, direct emissions and electrical consumption, but does not include scope 3 (refined, transport and use of gold). In addition, a part of neutrality is achieved by buying carbon credits, As the company admitted. In addition, from International Energy Forum (IEF) warn that mining It still has great challenges in water, waste and safety, beyond clean energy. Making it sustainable implies transforming the entire chain, not just electricity. The double brightness of gold. In times of uncertainty, gold is again a financial refuge. But Bellevue Gold wants it to also be an energy transition symbol. The gold we buy in the form of a jewel or ingot could come from a mine that, for whole days, feeds only on wind and sun. The question is whether this case will be the spark that transforms all mining or if it will remain a brilliant exception in the middle of the Australian desert.

There are 225 hours from Oktoberfest, but only 222 beer. The remaining three hours are an agonizing wait for Germany

by

September 20 was the largest public festival pistolt. Held in Theresienwiese, Munich, all in The oktoberfest is hyperbolicand the liters of alcohol and the size of the beers that are going to be dispatched will not be less. However, few moments better define those party desires As I wait that has taken place before the start of this Bacchanalia German that will total 225 hours. It’s just three hours, 180 minutes, but for most they are an eternity. The ritual wait. There is something almost liturgical in those first hours without beer from the Oktoberfest, a collective voltage Remembering the early morning prior to a great family party, when the last details are refined and the house seems to contain your breathing. In Munich, in the Prado de Theresienwiese, that pause is Puebla de Pretzels, soft drinks and board games, and thousands of crowded bodies that have run, camped or paid by a hole to ensure a place under the canvases of the great lying. The ceremony It is simple and strict: The doors open at nine, the enclosure is filled with expectation and tiredness in equal parts, and it is not until the mayor wields the shooter and nailed the first tap at twelve o’clock when the crowd exhales and the drink, literally and symbolically, begins to flow. Those minutes (three exact hours In which beer is still promise) they distil a delicious anxiety, attendees occupy their place not because of the drink itself, but because of the experience that the jug makes possible: band music, dance on tables, the conversation that becomes collective anthem. The social mechanics of the first third. The history I remembered this weekend The New York Times on the occasion of the start of the massive festival. The waiting ritual also reveals a unwritten economy and a complex social choreography: groups that keep hours in the tail, young people who transform their patience into income selling accesses, families that play cards to spend time and waitresses who, before becoming Athletes Of the napkin and the jug, they are the guardians of that temporal border between emotion and ethyl catharsis. The seats within the historical tents They rarely reserve For the general public. Most are first arrivals, and competition for a good table can involve entire nights on the street. Inside, stories are shared, instant fellowship networks are woven, it is purchased A great pretzel To simulate composure and You drink prosecco In somewhat shy sips that are, in reality, the prologue. And when the countdown reaches its end, the explosion It is ordered ” of Festbier On the wooden tables. The Oktoberfest numbers. The truth is that the Oktoberfest is not just a party: it is An economic engine and a cultural scenario that moves millions of visitors. The price of a jug It may seem high For those who measure it in liters and cents, but the real value of the experience combines tradition, gastronomy and show. Young people who repeat the visit year after year are part of a generation that sees at the festival A seasonal rite: A place to measure resistance and find community. At the same time, demand Create microeconomies: Plazas Belings In the row, improvised services, street vendors that capitalize on the wait with pins or memories and the hotel industry that collapses and reconstructs around the dates. The emotional and physical cost also weighs: the posterior euphoria is accompanied by fatigue and the inevitable account count and, of course, hangover. Rituals and practices. The tentseach with Your personality and clientele (The historical ones where tradition weighs, preferred by young people, which attract everyone …) are microcosm with their own codes. There it is sung, dance on the tables, gigantic bread is shared and liters are consumed in a choreography that requires skill: measured gestures not to overwhelm the jug, deployment of synchronized toasts, greetings that cross languages. The role of the waitresses is central; As we said, they are the invisible army that maintains the rhythm, joining physical strength and memory of usual faces. And that First “O’Zapft is!” (It is already open!) Not only frees beer, releases social permissiveness: for a few hours, the unwritten rule of the decorum softens and the city is allowed to dance on tables with the solemnity of a carnival. Youth, businesses and limits. As in every great local event, he is accompanied by the same endemic evils: young people who monetize their patience, resellers that make early entrance into business, and a tension between the tourist who wants the rite and the place that lives it as a mass consumption. If you want, the phenomenon remembers how traditions, when They become globalThey acquire New layers: they become show, they are marketed and sometimes They disfigure. However, they also guarantee a continuity: the people who return every year, the families that transmit outfits and songs, the employees who see their most intense season in October. It is a fragile balance between authenticity and the fair, between cultural heritage and global market. Euphoria and memory. Oktoberfest Live from that transition (from tense calm to the runaway euphoria), and in that march it may summarize its charm: it is not the intake itself that defines the event, but the social fabric that is assembled Around waiting. It is the collective experience where the expected gesture of the mayor, the first tap and the first jar make of catalysts of a temporary communion. Sensation of sharing something that transcends the glass and stays like memory. And while some counting liters, others keep anecdotes, small evidence that a festival can be simultaneously industry, tradition and catharsis, although yes, always starting (as every year) with the same expectant calm of three hours that announces, inevitable, beers.

Tour the entire Madrid subway in just 12 hours

by

His name is Adham Fisher and his name is in the history books. Provided that we put in that bag the bizarre challenges that They are collected in the Guinness book of the records. His crushing is as simple as crazy and strategic. Fisher is the man who has taken less time to travel all the Madrid subway lines. No matter the order, the arrival station or the departure. It only matters to have gone through each and every one of the stations that are part of the Madrid Metro network. The record has been held since 2017 When he registered 12 hours, 15 minutes and 48 seconds touring the Madrid subsoil. The judges’ note says the following: “Adham possessed the record to travel faster the Paris subway and that of New York.” Also a notice: “record attempts will not be admitted if the applicant is under 16 years.” It is not mentioned in the notice if it is a matter of security or that they understand that with less than 16 years there are better plans than spending half a day underground running between stations. Anyway, Fisher has returned to Madrid. And it has an objective: to lower your time. Noon under the ground Adham Fisher’s relationship with the Madrid suburban is long. Although his best time in Madrid dates from 2017, he also held a record with 13 hours in the accountant. And although he tells ABC who knows that at least some students have tried to snatch their record (The attempt was carried out in 2021)we do not know if there have really been many more attempts. The strategy is the same as the one that already told The world That same year. Then I tried to find the limits of Madrid’s vicinity and, as on this occasion (Fisher is one of the claims of the European Mobility Week In Madrid), he already pointed out that the project takes a lot of study, noting the times in stops and Analyze what its origin and destination should be. Of course, keep them a secret until the challenge is launched and finished, if there is luck, to the edge of the half -time. This time, Fisher was doubtful. Madrid Metro Line 6 is being renovated And therefore, it is largely closed. It was not a big problem for the British who uses the special bus service that the city has available to follow the line of the line. However, perform part of the path on the asphalt already seemed an insurmountable handicap. And although Fisher also knows what he faced because He already tried to tour all London’s bus lines In less than 24 hours, from the Madrid subway they have confirmed that, finally, the British has preferred to devote its passage to Madrid to take times for a future attempt. These successive attempts and their years of dedication hatched three years ago in a documentary called Team Fisher in which his attempt is to travel the 272 stations of the London Metro before the end of the day. And he also tells his experience in the book Tube Challenge: The Ultimate Ride. And is that the challenge of touring all the stations of the London suburban It began in 1960. Since then, they have accumulated to 22 new records that, yes, dance slightly in the number of stations. At the moment, the innumerable works by Madrid It seems that they have delayed a new attempt by the British that has been one of the subway claims for this week mobility. But something tells us that we will find it again in one of the hundreds of platforms of the Madrid Metro, notebook and stopwatch in hand.

There is a renewable energy source that works 24 hours a day, and Japan has opted for it: osmotics

by

Omnipresent wind and solar energies have the same problem: intermittency. The wind does not always blow and the sun does not always shine. This dependence on weather conditions It forces us to look for storage solutions OA depend on a 24/7 available source to have a constant supply. But what if that other source was also renewable energy? Japan bets on osmotics. In August, the Japanese city of Fukuoka launched the First osmotic energy center in the country. It is just the second installation of this type in the world and represents more than a pilot test for a technology that promises to revolutionize the energy mix. “I hope it extends not only in Japan, but throughout the world,” said Akihiko Tanioka, an expert in the field of the Tokyo Science Institute. The plant will generate about 880,000 kilowatts-Hora a year to feed part of the desalination plant that supplies fresh water to the city. Although it may seem like a modest figure, equivalent to the consumption of about 220 Japanese homes, its true value is that it works continuously. It is not affected by the weather or time of day, and does not emit carbon dioxide. The power to mix fresh and salted water. Osmotics is a new generation renewable energy based on A natural phenomenon that we all study at the institute: osmosis. When two solutions with different salt concentration are separated by a semipermeable membrane (which lets the water pass, but not the salt), the water of the less concentrated solution flows naturally towards the most concentrated to try to balance the mixture. Fukuoka’s plant places fresh water (treated wastewater) on one side of the membrane, and salt water (sea water) to the other. Fresh water crosses the membrane to the salt water side, increasing volume and pressure on that side. The conression is used to move a turbine that, connected to a generator, produces electricity. Therefore, this renewable source is also known as saline gradient energy or “blue energy”. From the initial promises to the first problems. This technology is not exactly new. Already in 2017, in Xataka we echoed its enormous potential: The studies suggested that it could generate up to 40% of the world energy demand if it would be used in the mouths of all rivers. The challenge was the efficiency of the membranes and the cost of the facilities. The first systems, such as delayed pressure osmosis, suffered bioincructing problems: bacteria blocked membranes, drastically reducing their effectiveness. Other systems, such as “inverse electrodialysis”, were more durable but generated very little energy. The Fukuoka plant, like the first in the world inaugurated in Denmark in 2023 by the Saltpower company, demonstrates that progress in membrane technology is allowing to overcome these obstacles. Nanotechnological membranes. In France, the company Sweetch Energy has developed Much more efficient nanometric size membranes, capable of generating between 20 and 30 watts per square meter. In comparison, the most advanced systems to date generate 12.6 watts. The company seeks to install its first real -scale generator, Osmorhône 1, at the mouth of the Rhone River. The potential of this unique river would reach 500 MW, equivalent to mid -nuclear reactor capable of supplying two million people. And it would be just the beginning. All deltas and estuaries in the world release 30,000 energy from each year, a figure similar to world demand of electricity. Salina bachata in Fukuoka. In addition to the friction of the membranes, the osmotics also loses energy in water pumping. But, as he explains The Guardianthe new Fukuoka plant uses the concentrated brine that remains of the desalination process to increase the salinity difference and, thus, the energy potential available. The inauguration of the Japanese plant and the advances of companies such as Sweetch Energy mark a turning point for the osmotics. They are the first steps to stop being a laboratory promise and become an industrial reality. In a clean, permanent energy, which does not depend on the climate and that can be integrated into existing infrastructures such as ports, desalination makers or locks. Japan has made its bet: the mixture of fresh and salted water will be part of its energy mix.

We have a big problem with plastic. This caterpillar can help us devouring a bag in 24 hours

by

The global plastic crisis, a problem that It takes centuries to degradeI could find an unexpected ally in the world of insects. A team of scientists He has revealed how the caterpillars of the wax worm (Galleria Mellonella) are able to devour and metabolize polyethylene, The most common plastic in the worldat an amazing speed. However, they have a deadly cost for them. A decomposition that is not perfect. The investigation, presented at the Annual Conference of the Experimental Biology Societyreveals that these caterpillars, nicknamed “plastivorous”, not only chew the plastic, but that they decompose metabolically and make it an body fat in a matter of days. The most shocking data: some 2,000 caterpillars can end a standard polyethylene bag in just 24 hours. The problem of the plastic diet. Polyethylene is the plastic that we find in purchase bags, containers and endless daily use products. His chemical resistance makes it incredibly durable and, therefore, A persistent contaminant. The finding that a living being can decompose it naturally opens a Revolutionary door for waste management. However, the solution is not as simple as let out millions of caterpillars in landfills. Dr. Bryan Cassone, professor at the University of Brandon (Canada) and project leader, explains the great inconvenience: an exclusive plastic diet is deadly for worms. “They do not survive more than a few days with a plastic diet and lose a considerable mass,” says Cassone. It is as if a human swells with fat. The process is similar to that of a human consuming excess fat: The caterpillars turn the plastic into lipids that accumulate in their adipose tissue, but without the necessary nutrients to survive. It is not the first time that this possibility is explored. Given the seriousness of this problem, science does not cease in its attempt to find a solution to disintegrate the plastic we generate. Thus, in 2022 a group of Australian researchers They verified the ability of the ‘super worms’ to devour polystyrene thanks to an enzyme they had in their metabolism. But these same wax worms, object of this study, also They were already protagonists of an investigation where the capacity they had to decompose the plastic was proven. This study has taken a step further to perfectly understand its processing system and the repercussions it can have. Towards a sustainable solution: supplements and bioengineering. Although the fact that the accumulation of fat is an obstacle to research, scientists have turned this fascinating biological process into a viable solution already a large scale for pollution and for this they point to two main roads: create a mixed diet and replicate the process in the laboratory. Create a mixed diet. Scientists are experiencing with “co-supplement”, such as sugars and other stimulants, to mix with polyethylene. The goal is to formulate a feed that not only keeps the caterpillars alive, but to optimize their ability to degrade plastic, creating a circular economy system where waste becomes food. Replicate the process in the laboratory. The second way is even more ambitious. It consists of thoroughly studying biological mechanisms and intestinal microbiome of caterpillars to identify enzymes and bacteria responsible for the decomposition of plastic. If they get it, they could replicate this process of “biodegradation” in an artificial way and industrial scale, without the need to raise insects. And right now there are a lot of daily products that have been generated thanks to the use of bacteria, fungi or enzymes. In this way, the fact of extrapolating this process to the industry can be the most intelligent to control the management of plastics. From garbage to the plate. As if solving one of the biggest environmental problems were not enough, this research could have a positive and unexpected economic impact. The massive breeding of wax worms would generate a huge amount of insect biomass. According to Dr. Cassone, these worms could become a very nutritious food source for aquaculture. In this way, a waste as problematic as plastic could be revalued to enter a new value chain, contributing to the food industry.
