China has reached the asteroid that has been driving astronomers crazy for a decade. And your first photo is already changing the answer

by

After 400 days of travel, the Chinese Tianwen-2 probe has reached your goal: object 469219 Kamo’oalewa (2016HO3). The entire world astronomical community has its sights set on this trip, for the answers it can provide to a mystery that has been going on for more than a decade. However, as usually happens with missions carried out by China, we had little information about the journey until the ship was already at its destination. This occurred on July 4, although the Chinese National Space Administration, CNSA, announced it this July 6. Be that as it may, the important thing is that China has reached Kamo’oalewa, that terrestrial “minimoon” that has given scientists so many headaches since it was discovered in 2016. Now comes the good. Tianwen-2 was released on May 29, 2025. 400 days later, it has reached its first stop, just 20 kilometers from Kamo’oalewa. There, he has taken the first photos, which will help him map this object, in order to determine the best places for sampling. Then, it will be time to get down to work, to collect a series of samples that will be sent to Earth in 2027. Then, we will have a definitive answer to the million-dollar question: Is Kamo’oalewa an asteroid or a fragment that was ejected from the Moon? The instruments. This probe has 11 payloads, including instruments that will allow it to study both Kamo’oalewa and its next target: comet 311P/PANSTARRS. These instruments include cameras, laser measuring devices, spectrometers, sonar radars and particle analyzers. It also includes the DIANA dust analyzer, developed in Italy. First mission: map the surface. Currently, the Chinese probe is taking photographs from different angles to create a 3D model that will allow establishing the best places to take samples. Broadly speaking, these places must meet two requirements: be scientifically interesting and not pose risks for sampling. The latter includes, for example, no unstable ground or loose rocks. Second mission: take samples. Since the mission left without knowing exactly what the surface of Kamo’oalewa will be like, Tianwen-2 travels prepared to take samples through three different methods: suspension, touch and match and anchor and coupling. The first consists of keeping the probe in hover, without landing on the object, and taking out a robotic arm that will skim the surface to obtain the samples. The second method, on the other hand, uses a disc-shaped, gas-powered head that briefly but more strongly touches the surface. Afterwards, rotating brushes are released that, together with bursts of air, sweep away the material released with that blow of the disc. Finally, the anchoring and docking method consists of releasing four robotic arms that are fixed to the surface to extract material for a longer period of time. It would be the first time this method has been used in deep space. Tianwen-2 has been traveling for 400 days Third mission: send them to Earth. The samples will be sent to Earth in 2027 for analysis. However, during Tianwen-2’s flyby of Kamo’oalewa, some inquiries are already being made about it. Asteroid or lunar fragment? Until now, all that was known about Kamo’oalewa were hypotheses or estimates. It was believed to measure between 40 and 100 meters in diameter and that It had to be a fragment released from the Moon after a collision or an asteroid. The first hypothesis arose from a study using spectrometry, in which it was concluded that its surface is rich in silicates, like that of the Moon. The second has several origins, although gained weight after another study in which several collisions were modeled on a simulated Moon. In very few cases the released fragments became quasi-satellites of the Earth, so the asteroid would fit better. In its first days in the vicinity of Kamo’oalewa, Tianwen-2 has made a measurement of the surface reflectance of the object, which suggests that it has a high geometric albedo. That of the Moon is quite low, so the asteroid hypothesis would still fit. On the other hand, the first data indicate that Kamo’oalewa measures 20 meters in diameter. It is less than what was originally estimated, but practically the same as what was calculated with observations made by James Webb. According to a study published on July 1in these it was calculated that it would measure 18 meters and, again, it was suggested that it be an asteroid. Specifically, one of type E. What is this about quasi-satellites? Kamo’oalewa is considered a quasi-satellite of the Earth because, when viewed from our planet, it appears to revolve around us. But it’s not true. In reality, this object revolves around the Sun, like the Earth. What happens is that it has a period similar to that on Earth. It also takes about a year to completely circle the sun. This, together with the geometry of its orbit, creates that optical effect that it is actually a kind of terrestrial mini-moon. Now we know that, possibly, in addition to not being a mini moon Due to its orbit, it is not made of fragments of our satellite either. At least, it seems most likely, although, of course, we will have to wait for the samples to reach Earth. Then we can definitively put the mystery to rest.

The Phantom 3500 wants to break the mold by changing the windows for screens. And he’s close to getting it

by

A year ago we told you the story of Otto Aerospace and its Phantom 3500, a windowless plane that aims to turn its walls into a panoramic view to the outside. As counterintuitive as it may sound, the company has had an idea: that on a plane without windows we can see better than ever what is around us when we fly. A year later, the project has been taking shape Otto Phantom 3500. Otto Aerospace’s Phantom 3500 is a project that should begin to come together next year. Last year we told you This curious project that aims to fill the fuselage of the plane with screens, eliminating all traces of windows. They called this concept Super Natural Vision, a system of screens that should show the outside in real time thanks to the use of cameras. This futuristic concept has, according to the company, the advantage of improving aerodynamics and thus the consumption of the device but also of simplifying the construction of the fuselage, saving costs. What’s new? To begin with, if you have entered the previous link you will have seen that the company has changed its name and is now no longer called Otto Aviation. Now, the company has adopted the name Otto Aerospacewhich gives an idea that its objective goes far beyond commercial transportation medianet private jets. But the most important thing is that the company has reached an agreement with flexjetwho operate huge fleets of private jets, to make the Phantom 3500 part of their fleet. The agreement contemplates a firm order for 300 aircraft and deliveries starting in 2030. It has not been made public how much the purchase figure is, which Yes, it is estimated in specialized media that the plane will cost about 19.5 million of dollars per unit but there is no confirmed figure for the purchase package of 300 aircraft of this type. Is it possible? According to its creators, of course. And with the purchase of 300 airplanes ahead, it had better be so, they will say at Flexjet. According to the company, the first flights of this private jet will begin in 2027 with a view to approval by US regulators. In his statement, Flexjet points that the purchase of 300 units of this device is one of the largest that has been recorded in private aviation and that it will serve to redefine what it means to fly using a service of this type. Can it be approved?. When launching this project, there is an important question that Otto Aerospace will have to answer. If you want to deliver the first planes in 2030, yes, you should have it under control. To approve an airplane, the Code of Federal Regulations of the US Government points out that “each emergency exit must have means that allow viewing the conditions outside the exit when it is closed.” That is, there must be a window or a reliable system that guarantees viewing of the outside without problems. And isn’t it very expensive? The other big question that Otto Aerospace will have faced is the issue of how much to fill the entire fuselage with screens. And to do this you will have to use high-quality flexible panels with a connection to your external cameras that is fast enough to not generate any type of dizziness as a consequence of a possible lag between the image and the movement of the vehicle. Likewise, filling the plane with screens also entails a cable management problem that will multiply compared to any other type of system and will add weight to the whole. Yet, The company claims to reduce consumption by half of fuel from other private jets that are currently in operation.

AI browsers arrived with the promise of changing everything. Not only have they not done it: they are a danger

by

Artificial intelligence browsers did not come promising a smarter tab or a search engine with better answers. They arrived with a much greater ambition: OpenAI talks about getting closer to a “true super assistant”, Perplexity summarizes Comet as “the browser that works for you” and Google presents Gemini in chrome under the idea of ​​a new era of navigation. The promise is clear: that we stop moving around the web alone and start delegating part of the way. The problem is that that same promise is beginning to show a more delicate side. The warning. The University of Washington has now focused on this emerging risk. In an investigation Presented at the Agents in the Wild workshop, and released by the university itself on June 30, a team analyzed seven popular agentic browsers to see how they relate to basic protection of the modern web: the same origin policy. Their conclusion was clear: four of them opened relevant risk avenues and the researchers managed to run a complete proof of concept in ChatGPT Atlas in Agent Mode. The bottom jump. A traditional browser shows us pages and waits for our decisions. We can open a service, copy data, paste it somewhere else, compare options or fill out a form, but each step depends on us. Agentic browsers alter this logic because they incorporate systems capable of interpreting what appears on the screen and moving forward within the browser itself. We are no longer just talking about summarizing a page, but rather coordinating tasks between tabs, operating on open pages and completing actions that were previously left in the hands of the user. A new front. The risk does not arise just because a page is malicious, but because the agent can interpret that page as part of its instructions. That’s where he comes in prompt injectiona technique in which external content tries to alter the behavior of the model with hidden, camouflaged or simply inserted commands where the user does not expect to find them. In a chatbot, that is already a problem. In an agentic browser, the scope changes, because the system can process information from a page and convert it into actions within the browser. The barrier that was there. The same origin policy is one of those protections that we rarely see, but that underpins much of the modern web. Its function, simply put, is to prevent one page from freely reading or manipulating information from another just because both are open in the browser. Thanks to this separation, any website should not be able to simply access what we have in a bank, an email or a private service. The problem arises when an agent groups together information that was previously much more separated. Let’s imagine that we visit a seemingly normal page and ask the agent to summarize it or help us complete a task within it. Under certain conditions, that page may include content from another source, such as an iframe, along with a malicious instruction intended for the model and not for us. If the agent has sufficient permissions, it could access content that the attacking website should not be able to read directly and move some of that information to a form controlled by the attacker. The web would not have directly broken the barrier; he would have used the agent as a bridge. The important nuance. It should be noted that the study does not say that all users will suffer an attack or that any browser with AI is insecure by definition. The researchers analyzed specific versions, at a specific time, and worked with proofs of concept, not with attacks against real services or with sensitive user data. They also observed relevant differences between products: browsers that granted fewer permissions to the agent tended to reduce risk. The paradox. These browsers are attractive because they promise to save steps, understand pages, relate information and execute tasks with less intervention from us. But that same capacity is what makes the failure weigh more: it does not occur only in an isolated tab, but in an environment where there may be open sessions, personal data and pending actions. They may not yet be a massive habit, but the security debate is already here, precisely because their proposal consists of giving them more margin.

Spanish oil is changing radically and we are only now beginning to realize it

by

There was a time when some olive oil jugs came with an anti-theft alarm. Those were the years in which the liter was close to ten euros and analysts wondered if the EVOO culture was dead. Traditional producers were drowning between meager production and falling demand. That was all two years ago. Now things have changed. Now prices are at rock bottom and, as a consequence, more than 75% of the Spanish olive grove, according to the association of olive municipalities, already produces below costs. The data is accurate; the producers are still drowning; The panorama is desolate. However, none of this means what it seems. The 75% figure. The assembly of the AEMO (Spanish Association of Municipalities of the Olivo) met in Adamuz and advanced its cost study for 2026. According to its calculations, the price at origin is 3.51 euros and that means that More than 75% of the olive growing area is already producing at a loss or at the limit of profitability. It makes sense. The AEMO does a more subtle job than we usually see and elaborates not “a cost” but sevenone for each cultivation system. As soon as we start to think in those terms, the olive grove stops being a ‘sea of ​​olive trees’ and becomes a very complex agro-industrial system. To give us an idea, the costs of the traditional mountain olive grove are about 5.31 euros per kilo, while the irrigated hedge is 3.07. Thus, with the average price of 3.51 euros, the hedge gains money and the traditional mountain hedge loses almost two euros. The hunger games. To be fair, we have to recognize that the AEMO is ‘part’ in this discussion (it defends the traditional olive grove) and, furthermore, has not yet published the entire report. However, the figures fit with what we already knew: no matter what happens in the olive oil market, the result is always the same: the irrigated olive grove wins. This is so clear that there is a whole mad race for make all hectares irrigated that they can (at all costs at a social, economic and environmental level). The current situation… It has to do, above all, with excess oil: after some bad seasons, we have gone from around 666,000 tons in 2022/23 to around 1.4 million in the last two campaigns. As there is a type of olive tree that can continue to be profitable at very low prices, there are no real incentives to contain the supply and that exposes a good part of the industry to having to assume the losses to stay alive for another season. And why should we care about olive farmers now? In our country (and without going into speculation about how good or bad the sector is), the olive grove has a key role in the economic, labor and industrial structure of Empty Spain. It is a discreet and underappreciated role; but that undoubtedly forms part of the basal structure of a good part of the country. It is not an accident that the association that is moving this is of municipalities: the traditional olive grove is an issue of great territorial importance. Because we must not be fooled. We talk about surface, not production. The irrigated olive grove is much more productive and is increasingly important. What we are seeing is a change of model within the sector and, linked to that, we are beginning to see the consequences it will have in the medium term. Spiler: they will not be good for most of olive-growing Spain.

A sedentary lifestyle is not only destroying your body, it is also changing your personality

by

Sitting is a problem. Better said: sitting is a lot of problems. Sedentary lifestyle is the fourth risk factor for death globally and is behind one in four cancers of the breast, uterus or colon. And the thing doesn’t end there. Its impact is undeniable: it doubles the risk of cardiovascular disease and type 2 diabetes, slows down glucose metabolism, and reduces fat synthesis. In addition, with one hand it hinders the burning of calories; while the other causes loss of muscle mass, bone weakness and bone demineralization. But we have known that for a long time. What is not usually said is that, in addition, sitting changes our personality. The personality? Indeed. In recent years, researchers have been building a growing body of evidence associating physically inactive lifestyles with small (but measurable) declines in several personality traits over decades. Since 2018, We know that baseline physical inactivity predicts declines in four of the big five personality traits: responsibility, openness, extraversion and agreeableness. It’s true that the effects are small (and the evidence is observational), but they are surprisingly consistent. Does exercising protect our personality? It is not clear. As I said, the studies are observational: that means that we know that both variables go hand in hand, but not that one ‘acts’ as a protector of the other. However, we don’t always need clear causality to see where the problem is. And the problem sits at the very center of Western society. Spain is a good example: between 27.4% and 36.4% of Spaniards aged 16 and over declared themselves sedentary in their free time according to the INE. And they are right: if the WHO recommendation speaks of between 150 and 300 minutes of physical activity per week, almost half of Spaniards do not reach it. Sedentary lifestyle is, without a doubt, a silent epidemic that is straining our health system and, if these researchers are right, is changing who we are. Because, although there is debate about all thisthe idea that an active lifestyle is a protective factor for personality stability throughout life is gaining strength among experts. It is true that we do not know the specific mechanisms, but the psychological plausibility of the matter is beyond any doubt. It’s time to get going.

Every time the Vatican has warned of the danger of a technology, that technology has ended up changing the world. It’s up to the AI

by

Let’s do a little memory. The 15th century was ending and The Christian Church found the printing press wonderful.almost providential. The adoption of that invention by ecclesiastical institutions was enthusiastic because it allowed them to amplify their mission. It didn’t take long for the discourse to change noticeably. in the bull Inter multiplies In 1487, Pope Innocent VIII praised it but warned of its risks: the same thing that served to spread the word of God, could serve to spread heresies and false ideas. It was then that censorship was introduced according to which no book should be printed without the approval of the ecclesiastical authorities. That laid the foundations for the future Index librorum prohibitorum which established a list of prohibited works for all of Christendom. That didn’t go too well. Martin Luther precisely took advantage of that divine invention to distribute your propaganda during the Protestant Reformation, and if this movement ended up being successful it was undoubtedly thanks to the printing press. It is not in vain that Luther is considered the first author of best-sellers of history. The encyclicals in the face of technological advances Let’s move forward. In 1891 Pope Leo XIII published his encyclical Rerum Novarumpossibly the most famous social encyclical in history. In it the pontiff focused on the rights of workers as response to the disturbing Industrial Revolution. He denounced the concentration of wealth and new technologies “in the hands of a few,” and warned that this was turning workers into slaves. Let’s keep moving forward. 90 years ago, Pius XI launched his act Vigilanti Cura (1936), dedicated exclusively to cinema. It recognized the technological progress that cinematography represented, but warned that if it was not strictly regulated, it would become the greatest instrument of moral corruption and mass manipulation in history. That message would be accompanied by the encyclical Miranda Prorsus (1957), by Pius XII, which extended that warning to both radio and televisionwhich had as much or more capacity than cinema to be beneficial but also toxic to humanity. There have been other social encyclicals related to technology: Pacem in Terris (1963) by John XXIII spoke of the atomic danger, while Evangelium Vitae (1995) by John Paul II was a wake-up call against eugenic biomedical techniques and embryo manipulation. The curious thing is that most of these encyclicals were published many years after certain technological advances had occurred. That would make one think that there are one or several encyclicals dedicated to the internet, mobile phones or social networks. There are not, although these topics have been mentioned by the last Popes in other messages. Arrives Magnificent Humanitas Therefore it is surprising that Pope Leo XIV has dedicated an entire encyclical to artificial intelligence. He has done it just three years after ChatGPT was launched, and he has also done it with a unique title: Magnificent Humanitas (2026). A fact: Robert Fracis Prevost, Pope Leo XIV, graduated in mathematics in 1977 from Villanova University in Philadelphia. This encyclical follows a very clear historical line of argument: on many occasions in which a disruptive technology appears, the Vatican adopts the role of “ethical brake” and tries to warn of something relevant: technical and technological advances must be subordinated to human beings. In Magnificent Humanitas the discourse is known and reasonable: warning that large AI companies They will end up imposing their moral vision on the entire planet. It is not just that hyperscalers (Amazon, Microsoft, Google) or companies like OpenAI or Anthropic dominate this market in the commercial section: it is that this dominance also translates into a form of influence that is even more worrying than cinema or television were (and are). The encyclical also warns of how AI is causing a “cognitive displacement” in which human beings end up preferring that algorithms think for them instead of making a reflective effort. The text is very long (40,000 words, which is approximately equivalent to a novel of about 150 pages) and ambitious, and covers many more areas, but the univocal message is that of a warning about the dangers of this technology. If one looks at this entire catalog of papal warnings from a historical perspective, it is impossible not to see the paradox. Most of the technologies that the Vatican once denounced as existential threats ended up, in the end, making the world a better, more prosperous and more connected place. The printing press democratized culture, the Industrial Revolution raised the global standard of living, cinema and television enriched the collective imagination, and biotechnology saves lives. History shows us that these bad omens of the Popes never came to pass completely, but we must be careful. The value of these encyclicals is not in their ability to predict the future, but in their function as ethical counterweights. It’s okay and necessary that someone warns about the risks, because those dangers were and still are real.

We Spaniards are changing fishmongers for fish on a platter. And it is costing us very expensive

by

When your grandparents wanted to buy fish, they might have found more or less variety, but they had it easy: they went to the market or the fishmonger, asked questions, chose, paid and returned home with the purchase. Today things are somewhat more complicated. Or not. with consumption in low hours and food spending increasingly concentrated In supermarkets (to the detriment of neighborhood stores), it is increasingly common that instead of buying salmon, sea bream or any other fish on a counter, we take it from a refrigerator, already scaled, filleted and served on trays. The question is… Does that make it more expensive for us? What has happened? that the OCU just responded to a question that you may have asked yourself more than once if you usually consume packaged fish from the supermarket: Are you paying a premium? Would that filleted fish be cheaper if you bought it in the fishmonger’s section instead of on a tray? It is an interesting question if we take into account that Mercadona, the chain with higher market share of the country and agglutinator of more than 30% of the food distribution business in some parts of Spain, has decided retire their fish counters and bet on the sale of this product already prepared, packaged and arranged on trays. What has the OCU found out? In general terms, it is (indeed) likely that you are spending more money by taking home already packaged merchandise instead of buying it at the supermarket fishmonger. After carrying out a study in a dozen chains throughout April, the OCU concluded that “fresh fish sold packaged is up to 30% more expensive than that purchased at the fishmonger if they are small varieties, already cleaned and filleted.” That last nuance is important because the organization’s technicians verified that the percentage goes up or down depending on the type of product we are talking about. In some cases the extra cost of packaged fish compared to that sold over the counter shoots up to 45%. In others it narrows so much that it is almost imperceptible. “The answer is not as simple as it seems: in some cases, especially for smaller or portioned fish, we do pay a lot more to buy clean fish on a tray, but in others, for larger ones, there is almost no difference,” details the OCU. Can it go further? Yes. To begin, it is useful to know how your study was carried out. As recognizes the OCU itselfthe analysis is not as simple as writing down the cost (euros per kilo) of each product and then comparing. There are chains that only sell certain varieties of fish through a single channel (counter or trays). As if that didn’t complicate things enough, there is another key handicap: trays of filleted and packaged fish usually offer 100% edible product; That is, without bones, heads or any other disposable part, something that can happen with whole pieces from the fish market. And how did they calculate it? How can we compare the prices of trays of already cleaned fish with those we see in fishmongers, which usually show the cost €/kg of whole pieces? To solve it, the OCU was based on estimates from the Spanish Nutrition Foundation that they conclude that the edible part of the fish usually represents more or less between 55 and 67%, depending on whether we are talking, for example, about sea bream or sea bass. As for the chains, the OCU set in Ahorramás, Alcampo, Aldi, BM, Carrefour, Dia, Hipercor, La Despensa, Lidl and Mercadona. If we talk about gender, the analysis focused on four species frequently consumed in homes: sea bream, sea bass, hake and salmon. For referencethroughout the year between October 2024 and November 2025, we Spaniards consume 0.56 kg of sea bream, 0.55 of sea bass, 1.44 of salmon and 1.54 of hake. Do those details matter? Yes. Because thanks to them we can better understand how the gap between the price of fish on the counter and on a tray widens or narrows depending on the product we are talking about. The clearest cases are represented sea ​​bream and sea bass. In the first case (gilthead) the OCU calculates that merchandise sold packaged is on average 27% more expensive. And at the counter we also pay for the amount of merchandise that is wasted after weighing the complete piece. In some supermarkets that percentage even shot up to 47%. The case of the sea bass is even more egregious. The surcharge detected in filleted products served on trays is 45%. Is it always like this? Things change considerably when we talk about hake and salome. If we want some slices or loins, there are no big differences depending on whether we ask the fishmonger at the counter or go to the supermarket refrigerator to buy them in trays. A hake cut and prepared on the counter came out in April for €17-25/kgwhile on a tray it was charged at €18-25/kg. The salmon slices or loins also cost practically the same (€20-23/kg) both in the fishmonger and in boats. What is the conclusion? “The conclusion is clear: in small fish, the greater the handling, the more expensive the fish on a tray becomes compared to selling on the counter. In preparations with less handling, the premium is much lower, if not residual,” ditch the organization. In short: there is a premium, although it is not always nor is it equally forceful in all cases. It depends on the type of fish and also the level of preparation we want. “In small and filleted fish, convenience does pay.” Better one or the other? The OCU admits that the trays have “pros and cons” for both consumers and supermarkets. Among the first, the most obvious is speed and comfort. One of its biggest drawbacks is the loss of the figure of the fishmonger, crucial for advising the client, and the generation of waste. The organization also warns … Read more

We are misdiagnosing PCOS. Therefore, these scientists have proposed changing its name

by

Polycystic ovary syndrome (PCOS) affects approximately 13% of women. women of childbearing age. However, it is estimated that there are approximately 70% of cases undiagnosed. Many patients are not aware of having this syndrome until they they try to have children and they see that it costs them a lot of work. Others never receive a diagnosis. For whatever reason, this is quite common in diseases that only affect women. All you have to do is see the endometriosis figures. Now, an international team of scientists has been exploring one of the reasons they believe there may be behind this underdiagnosis and have even proposed a curious solution: changing the name of the disease. Polyendrocrine metabolic syndrome of the ovary (SOM). These scientists they have spoken with experts and have surveyed more than 14,000 patients and healthcare professionals from around the world with different specialties. This has led them to realize that there is great discomfort with the name of the condition revolving around polycystic ovaries. It is true that this is a diagnostic criterion, but not all people with this syndrome develop this condition. Therefore, if the name revolves solely around that, there may be fewer diagnoses or even stigma towards those who insist that something is wrong with them, without having been able to put a name to their condition. After observing this data, they have chosen to propose a new name: ovarian polyendocrine metabolic syndrome. This refers to the factors that are common in all patients. An affectation of your hormones, which has effects on the ovaries and can also affect metabolism. It all starts with androgens. Generally, PCOS (or SOM, whatever we want to call it), is characterized due to excessive synthesis of androgens in the ovaries. These are what are colloquially known as male hormones, although they are also produced in the ovaries. However, its levels in the female body are usually much lower. When they rise, they affect the ability of the ovaries to ovulate correctly and, in addition, they affect the levels of other hormones linked to the menstrual cycle, such as LH and FSH. FSH usually tends to decrease, while LH increases. This hormone has many functions, among which is promote the synthesis of more androgens. Therefore, even more male hormones continue to be generated. It’s a vicious circle. The symptoms. People with this syndrome usually have symptoms such as absent or altered menstrual cycle, anovulation, facial hair growth, acne, hair loss or ovarian cysts. We should not confuse polycystic ovary syndrome with polycystic ovaries. The latter is a phenomenon that can be seen on ultrasound and does not necessarily mean the presence of the syndrome. For this reason it has been proposed to change the name. Continuing with the symptoms, PCOS is also usually accompanied by insulin resistance. That is the reason why it is also considered a metabolic syndrome. Other conditions, such as type 2 diabetes or obesity, can sometimes occur as a result. 2 of 3. PCOS is diagnosed when 2 of 3 diagnostic criteria are met. These are excess androgens, irregular or absent menstrual periods and polycystic ovaries. Cysts occur because, as ovulation cannot occur properly, the follicles in which the eggs mature remain. stuck in their immature state and accumulate. The egg is not released and the cyst occurs. However, is calculated that 30% of people with PCOS do not have these cysts. In fact, the percentage could be even higher. What happens is that, perhaps because of that inappropriate name, attention is not being paid to these cases. It is not definitive. The new name for PCOS is a proposal. Now, the competent health authorities, as well as other independent scientists, must evaluate it. In England, the NHS has already assured who will evaluate the proposal carefully. It’s certainly a start. Now we just need to pay much more attention to the suffering of women.

Three settings for iOS and Android that are more effective to avoid straining your eyes if you have presbyopia than changing the text size

by

If you are already a few years old and presbyopia is starting to make an appearance, don’t limit yourself to making the text on your cell phone bigger. Let’s tell you others three most effective adjustments to avoid straining your eyes that you can turn to, and that are available on both Android and iOS. These are three fairly simple adjustments that are not going to be as disruptive in terms of showing less content on the screen as when you increase the font size. However, they are going to be even more effective in helping you read. The key is contrast, bold and white balance. Expands screen contrast In the accessibility options of your mobile you have an option to increase contrast or high contrast text. By doing so, there were no more pale grays or blues that are difficult to read, the mobile will force the apps to show the maximum contrast in your texts to make them easier to read. You can combine this option with reducing transparency on iOS or disabling blur effects on Android, to eliminate some translucent effects that can make content difficult to read. Turn on bold text On iOS, within the text display and size section in the accessibility options you will have the option to activate bold text. With this you will make all the letters of the operating system, from the clock to the notifications, appear in bold. This will make all text easier to read without having to make it larger. In Android 16 you will have an even more advanced option, which is outlined text, within the Screen and text size section in the accessibility options. This will add a small border to each character to make it much easier to read, even when there are complex backgrounds behind it. Adjust the white balance The third setting that I recommend you try is the white balance. In iOS the option is called Reduce white pointand it’s in the display and text size settings in the accessibility section. On Android the equivalent is in the screen tone settings, within the section Screen. With this, what you will do is reduce the intensity of pure whitesnot the brightness in general. By doing so, the screen will be less bright, and it will be more comfortable for your eyes to read, especially when you are using your mobile at night or in poorly lit areas.

The superapp model that dominates in China never caught on in the West. something is changing

by

Superapps are mobile applications that offer many unified services, from messaging to mobile payments and much more. In Asia, especially China, They are the default formula that has been successful for years with apps like WeChat, Meituan or AliPay. In the West we are more into specialized apps, but the market is beginning to show clear signs of approaching the Chinese model. The Uber case. Uber just announced the integration of hotel reservations in your app through its alliance with Expedia. In this way, in the same app we have car reservations, food delivery and hotel reservations, a solution that is quite similar to the model of a Chinese super app like WeChat, which integrates all types of services under one umbrella. Uber’s goal is that, by offering more services, the Uber One subscription will be more attractive to consumers and thus increase its income. An important detail: Uber CEO Dara Khosrowshahi was previously CEO of Expedia, so this alliance does not seem coincidental. TikTok Shop. Uber is not the only one that is following this strategy, there are other proposals that also point in the direction of consolidation. We have the clearest example with TikTok and the integration of the marketplace. ByteDance has managed to export a very Asian model: see a product in a video and buy it without leaving the app. TikTok Shop has been in Spain since the end of 2024 and, at the end of 2025, there is already a TikTok account more than 12,000 stores operating on its platform. The adoption data is positive, but the model is still very far from the penetration it has in China. There have been attempts. The creation of a super app that succeeds in the West was Elon Musk’s obsession when he bought Twitter. The bet did not work out and today X continues to be what Twitter was: a microblogging social network. PayPal also tried its superapp version integrating hotel reservations with little travel. Years ago there was talk that WhatsApp could be the WeChat of the West, but despite having been adding functions, it is still a messaging app. Looking to the future, we have the case of ChatGPT and its path to a super app that integrates the chatbot with the Atlas and Codex browser. Why in China yes and here no. It is not a question of simple preferences, but has a structural explanation: Internet penetration in China was much slower and, in some ways, skipped the era of the personal computer. While Western consumers came to the smartphone with already formed habits (a browser to search, an email program, an online store), the Chinese did so directly from the mobile phone. By not having already created habits, this made the creation of these “everything apps” much easier. Likewise, the penetration of credit and debit cards was also slow and many consumers switched from cash to mobile payments, hence apps like WeChat or AliPay have become the default standard for paying everywhere. Another factor that plays in favor of the adoption of these apps is that they had no competitors. With the entire Google and Facebook suite blocked by the Chinese government, these apps did not have to compete, but rather filled a void. And of course there is the regulatory issue and institutional support. in China you can pay taxes from WeChatapply for a business license or pay a traffic fine without leaving the app, because the Chinese government actively integrated its public services into these platforms. In the West, the merger between a private company and the State would generate immediate political and regulatory scrutiny. something is changing. On the one hand, the perception we have of China from the rest of the world has been changing in recent years. The success of TikTok, the Labubu, the popularity of electric cars… are symptoms that China has become a cultural reference and technological. This opens a new opportunity for success. On the other hand, there is a new variable: AI. The arrival of AI tools is already changing our information-seeking habits and has the potential to function as a layer on top of everything we already use, connecting services that previously lived separately.
