NASA is looking for four people who want to live a year on Mars without leaving Earth

by

Space travel can leave no room for improvisation. Especially if the destination is a place as inhospitable and unexplored as Mars. Or even the Moon. Therefore, before the first astronauts set foot on the red planet and a new batch of humans walk on our satellite, NASA has decided to carry out a dress rehearsal here on Earth. Of course, it will not be done with astronauts, but with a group of volunteers willing to spend a year in a simulated environment of both the confinement conditions of the trip and the subsistence with limited resources that will mean staying at a base in either of these two places. The mission is expected to begin in 2027, no earlier than August, so the search for volunteers is still underway. Two missions in one. The mission, named by NASA as Moon and Mars Exploration Analogis a mix of two other previous missions: HERA and CHAPEA. Both consist of the use of facilities that simulate the extreme conditions of a trip to Mars or the Moon. CHAPEA’s facilities are larger (158 m2), as they simulate what the installed base would be in either of these two locations. HERA, on the other hand, consists of a smaller environment (60 m2), which simulates the confinement conditions of space travel. Therefore, what will be done is to dock the vehicle, based on HERA, to a larger, but isolated environment, in which there is everything from private accommodation for the crew to a common work space, including a recreation room, cultivation area, medical room, food preparation area, airlock and two bathrooms. They are not astronauts, but almost. NASA has announced that it is looking for volunteers, possibly because its astronauts are busy with other tasks. However, not just anyone can apply. To start, they must be US citizens or green card holders, between 30 and 55 years old, with a good command of English and a height that does not exceed 1.88 meters. On the other hand, they must have a degree in engineering, biological sciences, physical sciences or mathematics. Basically, just like astronauts. In fact, it is preferable that they have these qualifications at an advanced level. Finally, they should not have special dietary needsnor require help to sleep. Furthermore, in relation to sleep, they should not be sleepwalkers either. Of course, added to all this is that they will have to pass a series of tests, both physical and psychological. Come on, they’re not astronauts, but almost. Training for a fake trip to Mars. The four selected volunteers will have a pre- and post-mission phase dedicated to data collection. Additionally, before embarking on this year-long simulation, they will have to train and prepare for what will come next. In total, all this will last two months. All simulations. For one year, these temporary astronauts will live and work in isolation and confinement while simulating both interplanetary travel and operations on the planetary surface, including spacewalk simulations. It is expected that the results will be useful for missions as imminent as those of the Artemis programbut also for future even more exotic trips, including the long-awaited Martian colonization.

We have been believing for years that women live longer because of their lifestyle. Science has a much deeper explanation

by

If we take a look at the World Bank’s global statistics, there is an unbreakable pattern that repeats itself in practically every country in the world: Women live longer than men. Conventional wisdom often dismisses this phenomenon with a quick response based on lifestyle or “men take more risks.” And although there is some truth in this, the scientific reality is much more complex. Because? To understand female longevity, We must focus on the DNA that we have in all our cells. Something very basic is that women have two X chromosomes, while men have one X chromosome and one Y chromosome. A fundamental difference, because that second X chromosome in women acts as a kind of backup. This means that if a gene on one X chromosome suffers a mutation or is damaged, the female body can turn to the healthy copy on the other chromosome. Men, however, play a single card, since if their only X chromosome has a defect, there is no plan B. In addition, this chromosome is vital because it houses a large number of genes related to the immune system, which gives women a more robust response to infections. It goes further. Genetics is not everything here, but the body has an ace up its sleeve, which are the mitochondria, which are nothing more than the “power plants” of our cells. These organelles are inherited only maternally and, as proposed in 2007sexual differentiation has a direct biological cost for men, translating into lower mitochondrial function and, therefore, greater cellular oxidative stress that accelerates aging. The hormones. Beyond genetics and mitochondria, we must mention sex hormones, which are in very different proportions between sexes. Estrogens, for example, are the main female sex hormones that, in addition to regulating the reproductive cycle, act as a powerful antioxidant shield. Among its effects stands out maintaining the flexibility of blood vessels, reducing “bad” cholesterol and preventing inflammation. This largely explains why the incidence of cardiovascular disease in women is significantly lower before menopause. In the man. On the other side of the coin we have testosterone. Although it is crucial for the development of muscle and bone mass, high levels of this hormone in men are historically associated with increased cardiovascular risk at an early age and long-term depression of the immune system. The evolution. Someone may fall into the idea that this system is something exclusive to humans, but evolutionary biology shows us otherwise. Here, a 2025 study analyzed 1,176 species and the results revealed that in mammals, females live on average 13% longer than males. The reason lies in reproductive strategies and the biological wear and tear derived from male sexual competition, such as fights over territory or mating. However, it was seen that andIn birds, males live 5% longer; since in the avian world, males usually have two identical sex chromosomes (ZZ) and females have different sex chromosomes (ZW). Furthermore, in many bird species, parental care is shared or falls to the male, which reduces their risk behaviors. Human behavior. Of course, biology does not operate in a vacuum and genetic and hormonal factors must be added. the behavioral gap and social. For example, the consumption of toxic substances has a greater prevalence in men, being associated with cancer, cirrhosis or respiratory diseases. But, as we have said before, testosterone is also linked to a greater propensity to take risks, which translates into higher mortality rates from traffic accidents or cases of violence. On the other hand, women suffer from “invulnerability syndrome” which causes them to seek preventive medical services much more frequently. Men tend to postpone visits to the doctor until diseases are in more advanced stages, making treatment difficult. In addition, women tend to build stronger social and emotional support networks, a factor directly linked to greater survival in old age.

Earning $180,000 a year is no longer enough to live in San Francisco. The AI ​​boom has eaten up the technological middle class

by

In San Francisco you can earn $180,000 a year and not make ends meet easily. The AI ​​boom It is making what would be a huge salary anywhere else become mere pocket change, preventing entry into an impossible real estate market and a standard of living unattainable for the majority. Silicon Valley’s dream is to move. In it New York Times They tell the story of Katrine Razniak, a LinkedIn recruiter, and her partner Adam Woodbury, a software engineer. They have been in the city for five years and earn 180,000 and 185,000 dollars respectively, but despite this they are not able to get something as basic as an apartment for two. They spent months looking for a one-bedroom apartment to move in together on a budget of $5,000 a month, but it was impossible. They say they saw one for $5,200 and the waiting list already had 30 interested parties an hour after the open house. Buying a house is not an option either: The median home price is $1.7 million.. Given this situation, the couple is considering moving to another state where their salaries would allow them to live as an upper class. The new elite. While Katrine Razniak and her partner have to continue living in shared apartments, there is a new technological upper class that can afford to live comfortably in the city. They are the new millionaires of the AI ​​boom, employees of companies like OpenAI and Anthropic, with stratospheric valuations and stock options. In October of last year, when OpenAI was worth $500 billionwe already talked about that the city’s real estate market was exploding. Employees began selling stocks and buying homes like there was no tomorrow, causing prices to skyrocket. There is no improvement in sight. Not even a year has passed and Sam Altman’s company worth 852 billion dollars and Anthropic aims for 900 billion. To put it in context, when Uber went public in 2019 it was worth 82 billion, we are talking about ten times that amount. The imminent IPO of the two companies, added to the recent IPO of SpaceX, aims to create new fortunes, until 20 new billionairesaccording to estimates. Working in technology is no longer a guarantee of success in San Francisco, now you have to work in AI (and own stocks). It’s not just the rent. The median salary in San Francisco is also higher than the rest of the country and has been growing over the past six years, going from $153,000 to $196,000 today. However, everything else has also gone up. Aside from housing, life in general isn’t exactly cheap either. According to data from Cost of Living Indexthe cost of living in San Francisco is 65.6% higher than the rest of the United States. Katrine Razniak says her monthly spending has grown by $1,000 without changing her lifestyle, causing her and her friends to replace restaurant outings with home-cooked dinners. The housing problem in San Francisco. Spain is going through a housing crisis unprecedented, but we are not the only country facing this situation; Canada, Germany, Mexico, China o The United States are also suffering from it. In San Francisco specifically, the housing market is absolutely broken. As we said, the average price of a home is 1.7 million dollars, more than triple the national average of $450,000, and the rent is already the most expensive in the entire country, even ahead of New York. The demand is very high and the construction of new buildings is stagnant and the little that there is at a decent price ($5,000 a month is decent) flies in a matter of seconds.

He believes that in 20 years millions of people will live there

by

Blue Origin, Jeff Bezos’ aerospace company, does not stand still since the tycoon moved to Florida to be closer to their headquarters. Now Bezos has given an enlightening talk about how he sees the future of the space sector. The businessman believes that millions of people will voluntarily live in space in 20 years. Don’t be sad. During a talk with John Elkann (president of Ferrari and Stellantis) at the Italian Tech Week TurinBezos did not mince his words. The tycoon said he did not understand how “someone who is alive right now can be discouraged” about the future. The reason for your optimism? A near future where artificial intelligence, robotics and, above all, space exploration, converge in “multiple golden ages.” The future of humanity is not only on Earth; according to Jeff Bezos, it is about to expand exponentially through space. The role of Blue Origin. “I think in the next couple of decades, there will be millions of people living in space; that’s how quickly this is going to accelerate,” said Bezos, who I had already confessed in the past his expectation that Blue Origin will end up being bigger than Amazon. This optimism is not just rhetorical. Bezos is investing billions of his personal fortune each year to build new technologies for the commercial exploitation of space: New Glenn, Blue Origin’s heavy rocket successfully completed its first mission for NASA: launching the two probes of the ESCAPADE mission heading to Mars (the probes will set their final course for the red planet in November 2026). Blue Origin He also recovered the first stage of the rocket on the high seas, becoming the second private company in the world to achieve this. However, the year 2026 has been complicated: in May, the fourth New Glenn exploded on its only launch pad during a static power-up, destroying towers and key infrastructure. NASA estimates that the platform will not be repaired before 2028. Orbital Reef, the commercial space station in the form of a luxury hotel for millionaires that will have scientific modules for when the International Space Station is removed from orbit. The project overcame a series of habitability tests with real people within full-scale models of its modules, within the framework of NASA’s space station development program, which foresees that the first private platforms will replace the ISS in the second half of this decade. bluemoon, the lunar module with which Blue Origin It aims to surpass Starship by solving one of the big problems of the SpaceX ship: the evaporation of cryogenic propellants in space. NASA has assigned Blue Moon the mission Lunar Base Ischeduled for fall 2026, which will land at the lunar south pole. Blue Moon will also participate in the Artemis III mission (2027, in low Earth orbit) and in Artemis IV, the first manned lunar landing scheduled for early 2028. The explosion of the New Glenn complicates the launch schedules, although NASA is working to undock the lunar module from the rocket so as not to delay the mission. Other lunar developments, such as the ability to make solar cells from lunar regolith. Bezos was clear: “If you’re going to go to the Moon and stay on the Moon, you need to use the Moon’s resources.” Exploit the Moon and space. One of Bezos’ goals is to turn the Moon into an industrial launch pad. “The Moon is a gift from the universe,” he said, noting that its low gravity makes it cost 30 times less energy to launch a kilogram of mass from the Moon than from Earth. In his vision, the Moon becomes a “rocket fuel depot” that will allow us to explore the rest of the solar system. Bezos’ vision directly connects the space race with the other great revolution of the moment: artificial intelligence. AI is a technology with an enormous energy thirst, and its data centers are becoming a true “energy hole” on Earth. Bezos’ solution: get them off the planet. The proposal is build gigantic data centers of gigawatts in space. The advantages are obvious: “We have solar power there 24/7, and solar power there has no clouds, no rain, no weather.” It’s not science fiction. In fact, Bezos predicts that this apparent science fiction will be economically viable very soon: “We will be able to surpass the cost of terrestrial data centers in space within the next two decades.” Space, he believes, will go from being a place for communications satellites to being the center of heavy industry and data infrastructure. In the end, Bezos’ vision unifies all the revolutions underway. If AI and robotics will take over production, what is left for humans? According to him, the freedom to choose. Bezos doesn’t believe we need to live in space to survive. Robotics technology will be so advanced that “we will be able to send robots to do that job.” So why will those millions of people go? Bezos’ answer is simple: “The majority will live there because they want to.” A version of this article was published in November 2025 In Xataka | The first civilian to take a spacewalk with Polaris Dawn is a millionaire, but he also pilots fighter jets Images | Blue Origin

Tell me where you live and I will tell you which city is a climate sister to yours

by

Heat waves last longer and appear more frequently and there are also more floods and torrential rains: the weather has changed and the reason is climate change. Since a picture is worth a thousand words, you can see for yourself with this map with data since 1940 or, even more devastating, this other weather map in 2080. Or better yet, discover that, for example, in Seville the weather is the same as in some areas of Zambia or northern India. How do I know? Well, it’s not because I’ve been to any of those locations too much (three times in Seville), but because I’ve used the interactive map Climate Visualizedwhich is used to explore the weather patterns of any place on the planet using the classification of Köppen-Geiger. and find climate “brothers” throughout the world. This project is the work of Atlas Guo, a cartographer at the University of Wisconsin-Madison, and for its development he used the D3.js visualization tool and as a source, data from a scientific study (Beck et al. (2018)) who produced the most detailed global climate map that exists. Specifically, Guo uses the lowest resolution version (1 degree latitude per longitude), covering the period 1990-2020. From there, he turned it into an interactive and visual tool for anyone to explore. The Köppen-Geiger classification is the most used system in geography, ecology and climatology worldwide since it was formulated back in 1884 and the data from Beck and his collaborators made an enormous leap in precision. Having them at hand in an interactive and free graphical interface is a before and after, since reading and understanding a paper is something within the reach of few people, while with this project it is opened to the general public, curious people and students. The poster version of the project. Cartoguography At the end of the 19th century, climatologist Wladimir Köppen had a simple but powerful idea: classify all the climates in the world according to how much it rains and how hot it is every month. The result was five large climatic zones (tropical, arid, temperate, continental and polar) with up to 30 variants. Based on this, in 2018 Beck and his team updated that system with much more precise satellite and climate data (data from ERA5 and CHELSEA), producing the most detailed global climate map available. The study also estimates how those climate zones could change by the end of the century if emissions continue their current trend (RCP8.5 scenario), although that predictive part is not included in Guo’s web visualization. Other limitations to take into account are that it uses the lowest resolution of the study, which reduces the 30 Köppen climate types to 29 and blurs heterogeneities in coastal or mountain areas, which can be critical in more localized analyses. On the other hand, it remains in 2020, so it lacks the latest representations of climate drift. How it works The locations twinned with the time of Pamplona in the world. Cartoguophy Simply hover over a location or write in the search box to find out what type of climate you have and access monthly climate graphs, which are displayed in a side menu on the left: overview, temperature and precipitation. The months appear arranged in a circle, like a clock, starting with January. Each point on the circle shows both the temperature and rainfall for that month, all in a single drawing. In addition, that little dot is colored with a tone that you can find the same in other parts of the Earth. For example, Pamplona shares a climate with a good part of France, Belgium and Holland, but also with Melbourne, on the other side of the planet.

We believed that cities were a desert for bees, but 5.5 million live under this cemetery in New York

by

Although cities have their own fauna, the reality is that one could reasonably think that for animals of all kinds the urban environment is far behind the countryside in diversity and quality of life: there is a lot of asphalt, noise, pollutants… well yes, but no, because there is a place where bees have found a true residential paradise: a cemetery in IthacaNew York. Where you see a cemetery, the bees see paradise. It turns out that a laboratory technique called Rachel Fordyce had a trick to get to your work at Cornell University without paying for parking: park on the other side and take a walk through the East Lawn Cemetery. In spring 2022 he arrived at his post with a jar full of bees that he had found along the way: that was the beginning of it all. The bees inside were Andrena regularis, known as the “common mining bee,” a wild, solitary species that nests underground. That is, it does not have a queen and it does not build hives either. Each female digs her own tunnel, lays her eggs, supplies them with food, and seals them. And under the ground of the Ithaca cemetery there are millions, more specifically 5.56 million in just over 6,000 square meterswhich come out every spring to pollinate the surrounding apple trees. Why is it important. Because it is the largest population of wild bees with a nest in the ground ever documented and very far of the secondof 1.6 million individuals of a different species in Arizona. And their work is essential: pollinators in general are responsible for the production of approximately 75% of the world’s food crops. according to the FAO. As explains Bryan Danforthprofessor of entomology at Cornell University, they must be protected: “If we don’t preserve nesting sites and someone paves them, we could instantly lose 5.5 million bees that are important pollinators.” The most striking thing of all is that this enormous population was there, in the midst of civilization and next to one of the most prestigious universities in the world. Context. Contrary to popular belief, the most common way of life for bees is solitary and with a nest on the ground: approximately 75% of the bees on the planet live like this. Those bees that produce honey and live in hives may be the most famous, but they are an absolute minority. Solitary wild bees are not as well known, but their pollination work is key in nature and in food. Thus, this enormous population lives independently but concentrated in that place because the substrate conditions are optimal. The bad news is that pollinators are in decline: according to the report of the Intergovernmental Platform on Biodiversity and Ecosystem Servicesmore than 40% of pollinating insect species are threatened. In this scenario, finding such a large population in a city shows that there are more refuges for biodiversity than we thought and we must find them before they disappear (and if possible, avoid it). In detail. We knew about the presence of Andrena regularis in that cemetery since 1935, but it was not until 2021 when the scientific community began to intuit what was underground. To estimate the population, the team installed mesh traps at 10 points in the cemetery between March 30 and May 16, 2023. The result was extraordinary: as explains the press release from the New York university, is the equivalent of 200 honey bee hives on just 0.6 hectares of land and more than triple the population of Manhattan. Yes, but. The study has important limitations, such as that the population data is from a single spring (2023) and that the figure is a statistical estimate and not a real inventory, so we do not know if the population is rising, falling, remaining stable or how climate change affects it, which is advancing the flowering of apple trees and therefore altering the life calendar of the bees. And although it is the largest aggregation of wild nesting bees documented to date, its presence in a cemetery suggests that there may be others whose existence we are unaware of.

Madrid is a black hole of workers and students who live outside Madrid. And they just took away their transport pass.

by

No Autonomous Community lost as many inhabitants as Madrid in 2025. No Autonomous Community gained as many inhabitants as Madrid in 2025. It may seem paradoxical but is what the data says. Madrid has become a labor and economic black hole. And the consequences are obvious. It is the region that attracted the most population last year, adding more than 100,000 new residents. But it is also the one that lost the most population, with just over 12,000 people who have gone to live outside the Community of Madrid. The increase in house prices and the day-to-day cost of living is expelling some of its workers from the city. Some of them simply go to live far enough away to find more affordable housing with the promise that a quick train connection allows them to be just over an hour from their work. A good example is Valladolid. Those, perhaps, are the luckiest. Others have simply grown up outside the region, in a rural environment, and have come to Madrid to try their luck to get one of those jobs. statistics place only in large cities. Workers who, perhaps, simply They arrived in Madrid during their university days. and they have ended up staying. Unlike when they were in their twenties and returned to their place of origin every summer. Or workers who do not appear anywhere because they are irregular immigrants who have arrived in Madrid with the same promises as any other profile we have talked about before but that remain outside of any type of statistics. Madrid has decided to remove their transport pass from all of them. Or make it much more complicated. Unnecessarily unnecessary registration All the previously mentioned profiles could have access to the transport subscription of the Community of Madrid without any type of hindrance. All that was necessary was a DNI, a residence permit or a passport and to pay the corresponding fee each month. This transport pass allows you to take Metro, bus and Cercanías throughout the Community of Madrid, which is divided into zones. These areas even reach the closest towns in Castilla-La Mancha and Castilla y León and They range from 32.70 euros to 79.00 eurosdepending on the extension we seek to cover. Obviously, the pass is especially useful for those who travel by public transport to go to work or school, since it is a flat rate that in zone A is compensated after 40 or so trips. That is, if every week you take a train, a subway or a bus twice a day, the investment is already worth it. Much more if we take into account that the cost of the youth subscription (from 15 to 26 years old) is just 10 euros. But the Community of Madrid has announced something: you will have to be registered in the region or in one of the municipalities covered by the transport pass. (even if they are in one of the Castiles) to enjoy the flat rate. That is, this leaves out all those who have left the city to more distant municipalities, the students who do not register in the city because they return to their places of origin once the school year ends. Or immigrants who cannot prove their stay in the city. And the latter is what, everything indicates, has served as fuel for the Community of Madrid to make this decision. When the Government of Spain opened the door to the regularization of thousands of immigrants in April, some conditions were placed. One of them was to demonstrate certain rootssuch as receipts for rent, purchases… or being the holder of a public transport pass. The latter, because it is the simplest, filled the transportation offices with immigrants who wanted to get said transportation pass.. In response, in the Community of Madrid the requirements to obtain this card have changed and now they require proof of registration (unless you are a large family) in a municipality in Madrid or in surrounding regions. The result is that, automatically, immigrants in an irregular situation cannot get this transport pass but, as we said before, neither can workers expelled by the city itself, those who come to try their luck for a few months or university students. In The Country They point out that the Community of Madrid estimates that around 200,000 people are affected by this change, which will also be extended to all renovations in the future. That is, if you are not registered in Madrid and you renewed your transport pass last year, you will not have problems in a decade but it will be more complicated for those who renew it next year. The measure has sparked great controversy. And there are those who have pointed out the measure as “racist and exclusive”, as Oscar Lopezminister of the government of Spain and general secretary of the PSOE in Madrid, and of course numerous associations in defense of immigrants such as Regularización Ya, as reported in the newspaper. From the Community of Madrid they defend that The measure has been approved since 2011 and that has been delayed due to technical issues but in addition they have already opened the door for some autonomous communities to co-finance Madrid transport so that Your students can benefit from this flat rate. Those 200,000 affected barely exceed 3% of Madrid’s public transport users, but the economic hole is especially harmful to them. Right now, a university student who lives and goes to class within the city of Madrid pays 10 euros. If you take a bus and a subway each day there and back, you will make a minimum of 80 trips a week (Monday to Friday only). Without registering, you will start paying 58.40 euros. If you live in Madrid but study in another area beyond the city, you will pay at least 85 euros. The punishment is even greater if you combine the metro and/or the municipal bus with the Cercanías service. The situation is … Read more
