Apollo 11 first landed astronauts on the Moon in 1969, but the journey to the lunar surface actually began 43 years before, in snowy Massachusetts.

Exactly 100 years ago, on March 16, 1926, Robert H. Goddard launched the first liquid-fueled rocket. Liquid-fueled rockets would eventually provide the power to send humans to the Moon. Still, Goddard’s vehicle was small, flew for only 42 seconds, reached a height of a mere 184 feet and sustained damage that created more doubters than believers in the prospects for human space flight.

Despite this less-than-spectacular start to the space age, Goddard’s rocket was the beginning of a century of innovation. Today, hundreds of rockets launch each year. Giant liquid-fueled rockets combine liquid oxidizer – a substance that releases oxygen – and liquid fuel. These create chemical reactions that produce the explosive thrust necessary to propel humans to the Moon.

As a historian, I’ve spent 40 years studying the winding path that led to the development of modern rocketry. I’ve also seen how, over the past few years, private companies have played a much larger role in spaceflight than they did throughout most of its history.

Early days of spaceflight

After Goddard’s first liquid-fueled rocket launch, the development of American rocketry crept along at a snail’s pace until World War II. Nazi Germany’s invention of the V-2 missile proved that rockets could provide immense strategic and scientific value during both war and peace.

In war, the V-2 terrorized Britain and its allies. In peace, scientists looked at launching artificial satellites, or “moons” as they were originally called, to survey weather and boost intercontinental communication.

The United States government did not invest heavily in rocketry throughout most of the 1950s. Then, on Oct. 4, 1957, the Soviet Union shocked the world by launching the world’s first artificial satellite, Sputnik I. Millions of Americans feared that the USSR would soon rain nuclear missiles on them.

President Dwight D. Eisenhower and his advisers, however, displayed little anxiety at this prospect. They believed that America’s problems down on Earth were more urgent than those that might emanate from space.

Political pressure from the Senate majority leader, Lyndon B. Johnson, caused Eisenhower to reconsider. Late in 1958, the Republican president gave his consent for Congress’ establishment of the National Aeronautics and Space Administration. This new agency then went about selecting America’s first seven astronauts, introducing them to the nation in 1959.

Americans to the Moon

The arrival of a new, young chief executive, John F. Kennedy, sharpened the United States’ commitment to space. In September 1962, the president publicly challenged the nation to land an astronaut on the Moon before 1970. To Kennedy, the enormity of such a scientific and public achievement would provide unimpeachable proof to the world that the American way was superior to life behind the Iron Curtain.

JFK’s untimely death in the autumn of 1963 only served to strengthen the nation’s commitment to the late president’s lofty goal.

A mere five-and-a-half years later, astronauts Neil Armstrong and Buzz Aldrin walked on the lunar surface during the Apollo 11 mission. To get them there, NASA had spent nearly US$26 billion – $338 billion today. They had employed hundreds of scientists and engineers, and hired thousands of workers from dozens of contractors.

Yet, at almost the very moment the supreme triumph of Apollo 11 unfolded, public support for the manned space program evaporated. Preoccupation with the Vietnam War, economic inflation and nagging social and political inequality, as well as boredom with moonshots, led most Americans to turn away from the cosmos.

Richard Nixon, who followed Johnson into the Oval Office, slashed NASA’s budget. Three of the remaining lunar missions were abruptly and unceremoniously canceled. NASA had to abandon spectacular yet wasteful rockets like the Saturn V in favor of cheaper and more versatile launch vehicles.

Enter the Space Shuttle

Unlike earlier rockets, the next generation of rockets had to become almost completely reusable. The result: development of the Space Shuttle. NASA promised that the shuttle would launch no later than 1977 and that, when fully operational, it would rocket into orbit every two weeks.

That vision never materialized. By the time the first shuttle finally took off in 1981, it was grossly over budget. Problems with the heat tiles necessary for reentry persisted. Ultimately, the shuttles never came close to launching biweekly. Instead, only six to eight missions per year proved feasible. Worst of all, the program would eventually sustain two heartbreaking tragedies.

In 1986, the space shuttle Challenger exploded 73 seconds after takeoff. In 2003, Columbia – the first shuttle to ever reach space – disintegrated as it reentered the atmosphere over Texas. The following year, President George W. Bush announced that the remaining shuttle fleet would retire no later than 2011.

NASA’s air of invincibility and inexhaustible stream of funding had long vanished. The final shuttle flight served as a coda to the heady days of the 1960s and ‘70s.

Subsequent presidents talked of missions to Mars and created a Space Force, but the old Apollo launchpads at Cape Canaveral were abandoned, or “mothballed,” as NASA termed it. Thousands of workers were laid off. Leadership in space passed to private corporations like Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin.

Enter private companies

As early as 2006, NASA began contracting with SpaceX to launch its payloads and astronauts to the International Space Station. By 2024, SpaceX had realized the unfulfilled vision of NASA, launching on a nearly biweekly basis.

Meanwhile, while NASA’s Artemis program plans to send a crewed mission around the Moon using a launch system developed by the agency, the program remains years behind schedule. To date, it has cost at least three times more than originally budgeted.

Across the Pacific, China has announced that it will place astronauts on the Moon by 2030, with missions to Mars planned after that. For America’s rival on the world stage, government, industry and science all move in concert. Compared with China, the United States’ future in space appears far less unified, coordinated and purposeful.

A dynamic president once galvanized the U.S. government and its people to produce a “giant leap for mankind.” But since that July day in 1969, leadership in space has steadily passed from government to private hands, with the future of American space flight appearing murky.

A writing professor’s new task in the age of AI: Teaching students when to struggle

Source: The Conversation – USA (2) – By Kristi Girdharry, Associate Teaching Professor of Arts and Humanities, Babson College

I was early to the generative AI wave in higher education: I was among the first professors who teach writing to publish in an academic journal about generative AI and critical thinking, and I am now part of an interdisciplinary team at Babson College thinking about how AI is impacting education, industry and society.

But that does not mean I am all in on AI – nor am I anti-AI. I am pro-learning. As my co-authors and I argue in a forthcoming book on realizing the promise of higher education, even the most powerful tools are only as good as the learning environments we build around them.

So what does “getting learning right” look like in the age of generative AI? It involves a lot of experimentation and leaning in with students as a co-learner when I don’t have all of the answers, while remaining staunchly committed to sharing my expertise in writing, critical thinking and learning. I also hope that they trust me enough to follow my lead and persevere when the work becomes difficult.

From hope to grief

Navigating the rise of generative AI seemed easier to me in the earlier days. In spring 2023, for example, soon after ChatGPT went public, I asked students to use it to research their favorite musical artist and then fact-check the results as part of a unit in my senior-level social media class. The responses sounded polished and confident, but they were often wrong. Album dates were scrambled. Tours were invented. At one point, a student threw up her hands and shouted, “It lies!” The room erupted. The “lies” were especially apparent with less popular artists, about whom less had been written. “How might that translate to other knowledge areas?” I asked. They were pretty quick to thinking about whose voices might not make the cut in a different scenario.

While this was a promising start, by fall 2023 I found myself starting to grieve the passing of the pre-AI-everywhere world. Once again, I leaned in with my students, now in a sophomore-level research writing class. In their proposals, I included a new required section called “Be Better Than a Robot” – the gist being that if ChatGPT could write your research paper, what was the point of us spending weeks on it?

I asked: Where would your own work – your own human thinking – need to come in to create a tiny piece of new knowledge in the world? We practiced primary research, we used time during class for reading and annotating, and I extended deadlines to account for the rigor we were undertaking.

AI usage was discouraged but not outright banned: If used, careful and explicit descriptions of exactly how were required, and I even gave examples of things like brainstorming academic titles as a potential option. While not all of the final research projects seemed completely AI-generated, the few that did caused me to spiral – like it was my fault that I didn’t come down harder on not using AI when I was trying to be neutral and understand how we could use it as a tool and not as a replacement.

Cognitive blind spots

Since those early days in 2023, discussions around college students’ use of AI have only become more fraught and complicated. There are no easy answers, and there are a lot of fears about overreliance, loss of learning and even the value of a college degree. There are also plenty of ethical concerns that go beyond academic integrity, such as the environmental impact of AI and concerns over data and privacy. But AI usage is not slowing down.

Recent data from the Pew Research Center shows that more than half of teenagers are turning to AI for help with finding information and getting help with schoolwork. By the time these students arrive in my classes, many have already developed habits around these tools, and these habits may or may not serve their learning. For me, that’s not an argument for banning AI in the classroom, but rather an argument for taking it seriously.

But here’s the honest difficulty: When students use AI, they often can’t tell when they’re shortcutting their own thinking. A study published from late 2024 in the British Journal of Educational Technology found that students using ChatGPT improved their essay scores in the short term but showed no meaningful gains in knowledge. Moreover, they were prone to what the researchers called “metacognitive laziness,” meaning a dependence on the tool that undermined their ability to self-regulate and engage deeply in learning. This is a result of cognitive offloading.

Teaching discernment

At this point, I feel my role is shifting from neutral observer or co-learner to something more like a guide with a point of view. I know what rigorous thinking looks like in my discipline. I know the difference between a paper that has moved through genuine intellectual struggle and one that has been assembled. My job is to make that difference visible to students who may not yet have the experience to see it themselves.

So, yes, there are moments in my writing courses where I ask students to write without AI. Not as a purity test, although I could see it used that way, and not because I believe they’ll go on to spend their careers avoiding it, but because understanding what AI does to your thinking first requires knowing what your thinking can do without it.

This matters especially now as many college students I meet arrive already anxious, already performing, already optimizing for the grade rather than the learning. Many have spent years learning to produce the right answer rather than to wrestle with hard questions. Before they can develop discernment about any tool, they need something more foundational: a sense of their own thinking as worth trusting.

In practice, this looks like drafting with AI and without it, comparing versions, and being asked to justify choices out loud. It looks like noticing when the tool accelerates routine work and when it flattens complexity.

Like many faculty navigating this moment, I find myself in what Auburn University professors Christopher Basgier and Lydia Wilkes describe as an “unsettled middle,” neither fully embracing nor refusing the technology, but doing the uncomfortable work of engaging with it critically. My students, I’ve found, often end up in a version of that same uncertain space. Learning to sit with that uncertainty – to tolerate the slowness and mess of thinking things through rather than reaching for the frictionless answer – is where discernment begins.

If students are going to continue encountering these tools throughout their lives, then ignoring that reality does them no favors. My responsibility is to help them develop the judgment to decide when a shortcut is strategic and when it undermines their own thinking. That is pro-learning.

Controversy over Reese’s ingredients reveals standard food industry practices most consumers never notice

Springtime in Pennsylvania is peanut butter egg season. This year some consumers may taste the eggs a bit more critically and scrutinize the ingredients and label more carefully.

Reese’s, a Hershey brand, is known for combining chocolate and peanut butter in delicious and iconic ways. Reese’s products come in a variety of formats, called “line extensions.” These include everything from peanut butter chips for baking and chocolate peanut butter popcorn for snacking to limited-time offers for holidays – such as the popular Reese’s Peanut Butter Eggs for Easter.

On Feb. 14, 2026, Brad Reese, grandson of the founder, issued an open letter criticizing the Hershey Company for introducing line extensions – in this case, mini hearts for Valentine’s Day, with the flavors familiar to Reese’s lovers but made with cheaper ingredients, such as “chocolate candy” and “peanut butter creme.”

Ingredients like these seem similar but do not meet the FDA standards of identity for milk chocolate and peanut butter, the key components of the original Reese’s cups. For example, the FDA standard for milk chocolate requires at least 10% chocolate liquor.

Hershey responded in a statement: “As we’ve grown and expanded the Reese’s product line, we make product recipe adjustments that allow us to make new shapes, sizes and innovations that Reese’s fans have come to love and ask for, while always protecting the essence of what makes Reese’s unique and special: the perfect combination of chocolate and peanut butter.”

I am a certified research chef and food and hospitality professor in Philadelphia, where I founded the Drexel Food Lab, a culinary innovation and food product development lab. I am also a huge fan of Reese’s Peanut Butter Cups. When my older daughter was a toddler, learning her colors and shapes, I trained her to organize her trick-or-treat loot by separating the orange squares for dad.

As someone with decades of experience in product formulation, I am not surprised that the ingredients for some Reese’s products have changed over the years. One of my first jobs as an intern in corporate R&D was formulating cost reductions for existing products and later developing cost-effective line extensions building on the brand equity of the original product. What Hershey is doing with the Reese’s brand is Consumer Packaged Goods Marketing 101.

How food manufacturers deal with rising costs

Much has changed in the marketplace since Reese’s Peanut Butter Cups were developed by H.B. Reese in 1928 in Hershey, Pennsylvania, about two hours northwest of Philadelphia.

Inflation, tariffs, labor costs, fuel costs, employee benefits, competition and the vulnerability of climate-threatened crops, such as cacao, vanilla and sugar – none of which are produced anywhere near Pennsylvania – have made the confectionery business increasingly challenging.

When faced with rising costs, food manufacturers have three options:

1. Shrink the product. Reese’s Peanut Butter Cups have gradually shrunk from 0.9 ounce in the 1980s to 0.75 ounce today. That’s a 17% reduction. This phenomenon has been dubbed “shrinkflation.”

2. Raise prices. There is certainly a market for premium peanut butter cups, but how much will a consumer pay for the Reese’s brand? $5? $10? I suspect most consumers expect a single serving to be a couple of bucks at most.

3. Lower costs. While the company can improve operational efficiencies, changing the formula to reduce or eliminate high-cost ingredients is a standard industry practice to keep prices consistent for consumers in the midst of a dynamic supply chain. This phenomenon has been dubbed “skimpflation” and is Brad Reese’s main complaint.

Reformulations are common in the food industry. In addition to prices rising in general, a supplier could go out of business or have a shortage. A regulatory change or shift in consumer sentiment might prohibit the use of an ingredient. Wars, tariffs or climate change can raise costs temporarily or permanently.

Reformulations can be done well

Sensory and food science tools that we teach in our Drexel culinary and food science programs help ensure little market disruption and a consumer mostly unaware of the changes.

For example, a consumer discrimination test that food product developers love is a called the triangle test. Two samples from the original formula and one sample from the new formula – or vice versa – are presented to the consumer. If the consumer can identify the different one, the product developer did a poor job in preserving the beloved brand through the reformulation. But if consumers can’t tell the difference, the reformulation may be able to move forward.

Sometimes product developers get it wrong in introducing a new formulation. Some of us are old enough to remember Crystal Pepsi, the McLean Deluxe burger or Doritos made with olestra. These products failed, respectively, due to lack of defined consumer benefit, misalignment with the brand, and bad press due to digestive side effects.

But most reformulations go unnoticed – the good work of food technologists who strive to keep food safe, affordable and delicious for consumers.

So, are these new Reese’s products inferior to the original? Maybe. Like with taste in art or wine, if it tastes good to you, it’s good. If not, send the company a note like Brad Reese did.

A pet-friendly homeless shelter pilot reduced the rate of homelessness among the people it helped in California

Source: The Conversation – USA (2) – By Benjamin F. Henwood, Professor of Social Policy and Health, University of Southern California

When homeless shelters allow people to stay with their dogs and other pets, more unhoused people become more willing to stay in a shelter.

That’s what my team at the University of Southern California’s Homelessness Policy Research Institute learned when we evaluated California’s Pet Assistance and Support Program.

California’s Department of Housing and Community Development established this pilot program in 2019. Its goals were straightforward: to make homeless shelters more accommodating to people with pets – mostly dogs – so that people living on the streets don’t have to choose between staying in shelters or abandoning their pets.

The program disbursed US$15.75 million between 2020 and 2024 to 37 organizations across the state. The funding allowed shelters to build kennels or other pet-friendly spaces, provide pet food and supplies, and offer basic veterinary care. It also covered the costs of staffing and maintaining insurance required to operate pet-friendly shelters.

Evaluating the program

We did this evaluation in collaboration with My Dog Is My Home, a nonprofit that supports pet-inclusive housing and services for the homeless, and the American Society for the Prevention of Cruelty to Animals.

By all accounts, the program was a success.

We found that the program helped 4,407 people experiencing homelessness keep their pets while getting support. Many were able to enter shelters, and their animals received needed veterinary care. A total of 886 people ultimately moved into permanent housing with their pets – a higher success rate than the statewide average for homeless people in California.

Theoretically, this funding should have reduced the number of pet owners living on the streets. Yet since 2019, the year the program began, the number of homeless people in Los Angeles with dogs and other pets has increased.

I’ve seen this change firsthand.

Since 2017, I’ve led the USC research team that produces the annual homeless count estimates for Los Angeles. The U.S. Department of Housing and Urban Development requires this exercise for any city seeking federal funding for homelessness services.

One of the questions my team asks when interviewing thousands of homeless people each year is whether they have any pets.

Before the pandemic, we generally found that roughly 1 in 8 people did. We also found that nearly half of homeless pet owners had been turned away from a homeless shelter because it couldn’t accommodate their animal.

Despite programs like California’s Pet Assistance and Support program, my research team has found that the share of people living on the streets of Los Angeles who say they have a pet increased to roughly 1 in 5 by 2025.

Need for more pet-friendly programs

We still don’t know why the share of homeless people with pets has gotten so much larger.

It could be that rising housing costs, which is the main driver of homelessness, is pushing more pet owners into homelessness. Or, perhaps more homeless are adopting pets to deal with their social isolation and loneliness, two common conditions for people with nowhere to go.

Either way, proposed cuts by the federal government to affordable housing and homeless services will only make matters worse.

The number of homeless people in Los Angeles has fallen by more than 4% since 2023 to just over 72,000 people in 2025. But based on my research findings, I would expect the number of people living on the city’s streets – with and without pets – to rise over time unless more affordable housing becomes available.

And growth in the homeless population may be hard to avoid without more efforts like California’s Pet Assistance and Support Program – on a larger scale than the pilot we studied.

What ‘gooning’ reveals about intimacy in a world cordoned off by screens

Source: The Conversation – USA (2) – By Jennifer Pollitt, Assistant Professor of Gender, Sexuality and Women’s Studies, Temple University

Gooning usually involves streaming online pornography across multiple screens and browsers for hours at a time. Tero Vesalainen/iStock via Getty Images

Four years ago, I started a class at Temple University titled, “Social Perspectives of Digital Pornography: The Other Sex Ed,” centered on porn literacy, or what young people learn – or don’t learn – from digital porn.

I wanted to create a space to examine these issues, not from the assumption that pornography is entirely good or entirely bad, but that avoiding the conversation altogether only does harm.

Teaching this semester-long course to college students has given me a unique window into the virtual spaces young people turn to not, only when they want to be turned on, but also when they want to learn about sex.

Only recently did AI porn start to crop up in our class discussions. And this semester marked the first time that “gooning” and “gooners” entered our class’s collective consciousness.

If you’re unfamiliar with gooning, you’re not alone. Until recently, so was I. Then I began noticing it written on Post-its in the elevator on the way to my office – “gooner forever,” “goon life” and “welcome to the goonverse.” Soon I started seeing the term on social platforms and elsewhere: in Reddit threads, on TikTok, in video titles uploaded to porn sites and in memes circulating on X.

Gooning is a form of prolonged masturbation. The goal is not orgasm but staying in a sustained state of arousal for an extended period of time. Self-proclaimed “gooners” may deliberately delay or avoid climax to experience what they describe as a “goon state” – a trancelike condition characterized by reduced self-awareness and a sense of time distortion.

It draws on familiar sex techniques such as edging – the practice of delayed orgasm – and prolonged arousal.

But unlike edging, gooning usually involves streaming online pornography across multiple screens and browsers for hours at a time; frenetically edited videos, which are often called porn music videos, or PVMs; and, in some cases, real-time interaction with other gooners through online platforms.

Gooning isn’t just about masturbating alone in your room. It’s a community that appears to be born out of the broader dynamics of digital life: abundant stimulation, parasocial connection and forms of intimacy that can feel safer and more controllable than face-to-face relationships.

Stimulation overload

The more I learned about gooning, the more the scale and intensity of the visual stimulation stood out to me.

Gooners, awash in algorithmically curated sexual content designed to maximize novelty and attention, often stream these rapid-cut porn clips on multiple screens. Music thumps in the background. There’s no plot.

In other words, this isn’t like finding some X-rated VHS tapes or a stack of Playboy magazines tucked away in your father’s closet.

Gooning has also morphed into an identifiable online subculture, replete with a shared language, rituals, memes and groups hosted on platforms such as Discord, Reddit and X. Members recommend pornography clips, circulate memes and tell inside jokes. They share tips for extending or intensifying porn-viewing sessions. They also trade screenshots, discuss favorite performers or genres, and post encouragement to other participants.

Some see gooning as a form of sexual exploration or experimentation. For others, it functions as a coping mechanism for loneliness, anxiety or emotional distress. And for others still, it’s a place for community, belonging and joy in reaching the “goon state.”

Sex repackaged for the digital age

While gooning may feel new, elements of gooning have long existed.

Edging and delayed orgasm have been studied for decades in sexology and sexuality studies; practitioners of tantric sex and members of fetish communities also seek to reach trancelike states; and porn enthusiasts – whether they perused cam sites or collected magazines, VHS tapes and DVDs – have long participated in porn marathons.

Gooning simply packages old sexual practices inside a radically new digital landscape, one defined by physical isolation, an abundance of images and videos, and connection mediated through a screen. Though there is a communal element to gooning among users, intimacy toward performers is often one-sided: Content flows toward the user, affirmation is algorithmic, and arousal is engineered, rather than negotiated.

But to many gooners, that’s the appeal.

Intimate relationships with real people can involve rejection, awkwardness, time and emotional labor. In the “goonverse,” on the other hand, desire is predictable, endlessly available and never says no.

Focus and fragmentation

It’s important to remember that not all prolonged masturbation is pathological, and gooning illustrates a familiar pattern in sexual subcultures: When pleasure is abundant and easily accessible, transgression becomes a way to make it meaningful again.

Sometimes, when an experience becomes routine, people often seek to intensify it. Similar dynamics appear outside of sexuality as well: extreme eating challenges, endurance drinking games or ultra-spicy food competitions transform ordinary pleasures like eating or drinking into tests of excess, risk or spectacle.

Millions of Americans view porn every day, typically in private, spending roughly 10 minutes per session perusing.

Gooners, on the other hand, can spend hours intensely focused on masturbating while deliberately delaying climax.

The over-the-top excess twinned with control may seem appealing in a world where smartphones offer a mindless, constant and banal source of stimulation. For gooners, the arousal could come as much from the boundary crossing as from the sexual imagery itself.

Immersion without vulnerability

My recent class discussion on gooning was one of the most lively of the semester.

Whereas many students commonly use “to goon” as a verb, meaning to excessively masturbate, they were less familiar with the intricacies and inner workings of goon subculture and the lives of the gooners themselves.

The more they learned, the more some of my students became dispirited by what seemed to be a dystopian and lonely form of pleasure seeking. Others, however, were enthusiastic participants in the “goonverse,” taking great joy and pleasure in this form of sexual exploration.

The most revealing aspect of gooning may not be what it says about porn, but what it says about intimacy in the digital age.

In the U.S., dating apps have turned romance into a swipe-based marketplace. Influencer culture encourages one-sided, parasocial bonds. People present curated versions of themselves on social media. Relationships, attention and arousal are increasingly mediated by screens and shaped by algorithms. These shifts may also be changing behavior. Surveys suggest that Gen Z is dating less frequently, having less sex and spending less time socializing with friends in person than previous generations did at the same age.

“Gooning” is unlikely to be the last new term that enters my classroom. But there’s some logic to its rise in a digital world characterized by endless content, battles for attention and fleeting relationships. It offers immersion without vulnerability, community without physical presence and arousal without negotiation.

Sex, as it often does, is simply where the culture shows its hand first.

Anxiety and ADHD can overlap – here’s how to untangle these widespread mental health disorders

Source: The Conversation – USA (3) – By Deldhy Nicolás Moya Sánchez, Psychiatrist and Consultation-Liaison Psychiatry, Universidad Nacional Autónoma de México (UNAM)

Untreated attention-deficit/hyperactivity disorder can cause performance problems at school or work, leading to depression and financial stress. Pheelings Media/iStock via Getty Images

For decades, one of the greatest challenges to treating neurological disorders like attention-deficit/hyperactivity disorder is that its symptoms often resemble those of several other conditions. Overlapping disorders are extremely common when it comes to neurological diagnoses.

A child who struggles to sit still, focus or complete tasks could have ADHD, anxiety, a learning disability or simply be reacting to stress at home. A teenager who seems emotionally volatile and impulsive might be showing early signs of a mood disorder, ADHD or trauma. An adult who constantly misses deadlines, forgets important obligations and feels chronically overwhelmed might be dealing with workplace burnout, a severe anxiety disorder or undiagnosed ADHD.

I am a practicing psychiatrist at the National Medical Center “20 de Noviembre” in Mexico City, and a professor of medicine at UNAM, the National Autonomous University of Mexico. In my work, I frequently see cases that initially look like anxiety, but I often find that this issue is only the tip of the iceberg. Anxiety improves, and what emerges is undiagnosed ADHD.

The reverse can also be true: What looks like ADHD — difficulty focusing, restlessness, poor performance — sometimes turns out to be driven primarily by anxiety. However, in my practice, I most frequently see the opposite scenario. Young adults arrive seeking treatment for severe anxiety, but clinical evaluation often shows that their condition is rooted in executive functions – such as planning and problem-solving – that have been fragile since childhood. Patients in this situation have compensated for their undiagnosed ADHD for years through exhausting effort and the fear of failure.

Diagnosing untreated ADHD matters because in adults, this condition is associated with depression, anxiety, work difficulties, academic problems and financial stress.

Because these conditions are so tightly interwoven, it is not always possible to know which came first — and in many cases, both are genuinely present at the same time. Treating only what is visible may bring real but only partial relief, leaving the underlying driver unaddressed.

This is why evaluation by a clinician who can assess the full picture matters. When ADHD is properly identified and treated, secondary anxiety often resolves more completely than it ever did with therapy or medication alone. But the reverse is not reliably true: Treating anxiety does not correct the underlying attention issues that may be driving it. Identifying the right target – or targets – is what leads to lasting improvement. This comprehensive approach is especially important given the growing recognition that emotional dysregulation – such as intense, rapid mood shifts or an inability to manage one’s distress – is often a core, yet historically overlooked, symptom of undiagnosed ADHD.

Here’s why undiagnosed ADHD can hide behind anxiety, some signs that can help differentiate these two conditions, and why this diagnostic blind spot – treating the visible anxiety while missing the underlying ADHD – is so common.

How ADHD lurks

I had been seeing a patient in his late 20s for some time who suffered from anxiety when he came to an appointment convinced that he was finally emerging from a terrible year. He had stopped having panic attacks, was sleeping better and no longer lived intensely focused on his own body, waiting for the next wave of fear. After months of antidepressants and cognitive behavioral therapy, the crises seemed controlled.

But then something different emerged: constant difficulty concentrating, procrastination that left him stuck for hours, impulsive speech and a stubborn inner restlessness. These symptoms are often overshadowed when someone feels suffocated by anxiety and consumed by worries.

Anxiety and ADHD have many common symptoms, including restlessness, irritability, sleep difficulties and concentration problems. This overlap can lead to diagnostic errors and treatments that don’t address the root cause.

During childhood, many ADHD symptoms are interpreted as personality traits. A child may be labeled as distracted, inconsistent, impulsive or restless. Over time, these people learn to compensate through excessive effort, perfectionism or constant self-monitoring – strategies that raise baseline stress and may trigger anxiety years later.

When the brain leaves survival mode

Anxiety is often the first way the body expresses overload. When this threat response eases, previously masked struggles with planning, organization, sustained attention and time management surface.

Several studies show a strong association between ADHD traits, anxiety and depression. In the United Kingdom, recent research found that ADHD traits predict emotional problems more strongly than traits related to the autism spectrum.

Systematic reviews indicate that 25% to 50% of adults with ADHD experience an anxiety disorder at some point in their lives. Major depressive disorder is also more common among this group than in the general population. For many people, anxiety is the consequence of years trying to function with an impaired executive system, the part of the brain that manages planning, organization and impulse control.

Why ADHD can elude early detection

It can be easy for parents, teachers or co-workers to misinterpret ADHD symptoms as character traits. Impulsivity can be seen as bad temper, disorganization as laziness, and difficulty maintaining attention as lack of interest. In adults, these difficulties are often interpreted as personal flaws rather than neuropsychiatric disorders.

ADHD rarely causes physical symptoms, but anxiety does. Heart palpitations, intense fear or insomnia drive people to seek care, while attention symptoms are less recognized.

ADHD is strongly genetic, with inheritance rates estimated at 70% to 80%. This genetic component also means that closely related relatives have a higher risk of emotional disorders such as anxiety and depression. When several family members share similar traits, these attributes often are considered part of the family personality.

Primary anxiety versus anxiety due to ADHD

The key question in clinical practice is this: What remains when the anxiety decreases?

If emotional distress diminishes but the following symptoms persist, then the pattern aligns more with adult ADHD:

– prolonged procrastination

– difficulty initiating tasks requiring mental effort

– frequently forgetting instructions or appointments

– constant inner restlessness

– daily disorganization

– easy distraction by minimal stimuli

A formal diagnosis, made by a trained health professional, requires an assessment of symptoms that have been present since childhood and a determination that the patient is impaired in more than one life area. Caregivers will rule out other medical or psychiatric causes, using validated tools such as structured interviews and specific scales.

Neurobiological studies have shown that people with ADHD have identifiable differences in several brain regions, including their connections in the deep neural tissue known as white matter and the reward circuitry of the brain. They also have imbalances in dopamine and norepinephrine — brain chemicals that regulate attention, motivation and impulse control. These differences can make it harder for people to initiate tasks or sustain efforts.

The risk of treating only what is visible

Antidepressants and therapy can reduce emotional distress and overlapping symptoms such as restlessness or sleep disruption, but they do not modify the attention difficulties that create daily chaos – affecting relationships, academic performance and work functioning. If this root is not addressed, the patient improves partially but continues living in disorganization, leading to new cycles of distress.

When I explain how anxiety can mask ADHD to patients, their most common reaction is a mix of relief and frustration. They finally understand their emotional history, but see that they spent years interpreting their symptoms and struggles as flaws.

Studies show that adults with anxiety and untreated ADHD suffer greater functional impairment and more frequent relapses, meaning their severe anxiety or depressive episodes keep returning despite therapy or medication. They live under a burden of self-reproach that harms their self-esteem. This cycle can repeat for years: emotional improvement, relapse and seeking treatment again, without identifying the main problem.

The good news is that once ADHD is diagnosed, it is treatable. Robust evidence shows that treatment for ADHD reduces impulsivity and improves sustained attention and daily functioning at all ages.

Regulating dopamine and norepinephrine enables patients to initiate tasks and sustain their efforts until the work is completed. When this happens, secondary anxiety often decreases more deeply and stably because people no longer have to work twice as hard just to keep up. This also improves their relationships at home, school and work.

Identifying hidden ADHD does not erase the past, but it changes the future. When people understand the root cause of their anxiety and gain tools to manage it, they can move from surviving to living a more functional life.

The long history of silent meditation retreats and the individuals who helped shape them

Silent retreats have become increasingly common in the United States in recent years.

To calm down and reset their nervous systems, people relinquish their phones and reading materials and commit to speaking at a bare minimum to learn practices of self-awareness.

Silent meditation and silent prayer have shaped spiritual lives within a variety of religious traditions for thousands of years. Today, however, those practices are often being offered in secular settings.

One particular form of meditative silence, the 10-day mindfulness retreat, has had an outsized impact. Research I have carried out over the past two decades sheds light on the role of the Burmese meditation master Sayagyi U Ba Khin in popularizing mindfulness meditation. The term “sayagyi” means “respected teacher.”

Ba Khin was one of a small number of prominent Buddhist lay meditation teachers in late colonial and early postcolonial Burma. His silent, 10-day retreat became a model for a wide range of intensive meditation traditions. Three of Ba Khin’s students were instrumental in bringing his teaching to the United States.

The emergence of mass meditation

Mindfulness meditation practices can be traced to ancient India. The clearest historical evidence of such practices comes from the teachings of the historical Buddha, Siddhartha Gautama, and his contemporaries.

Most of these practitioners were monastics or ascetics. Historical questions remain, however, regarding whether such practices were primarily reserved for monastics or widely practiced among laypeople.

The monk and scholar Bhikkhu Anālayo argues that the oldest historical sources provide evidence for widespread lay meditation practice beginning in the fifth century B.C.E. Other scholars suggest that laypeople had access only to teachings on devotional practices, such as reflections on the qualities of the Buddha, that would encourage offerings and lay support for the monastic community.

A striking development in the mid-20th century was the emergence of mass Buddhist meditation movements in Southeast Asia. Countries such as Myanmar, Thailand and Sri Lanka promoted meditation among lay people to build national identities in the face of colonialism.

In post-colonial Burma – Myanmar’s name until 1989 – being an ideal citizen meant being an ideal Buddhist; meditation was seen as a visible expression embodying that ideal. With the globalization of such meditation practices in the latter half of the 20th century, such meditation practices expanded beyond the borders of these countries.

Following Burma’s independence in 1948, Ba Khin became its first accountant general – a role in which he developed a close relationship with the first prime minister, U Nu.

With the blessing of U Nu, Ba Khin began teaching meditation to his employees. At the time, many of his students were neither Burmese nor Buddhist; they were civil servants originally working for the colonial government.

The context of teaching was therefore both lay-oriented – taking place in work contexts – and religiously pluralistic, involving Buddhists and non-Buddhists.

Ba Khin had learned meditation from Maung Po Thet, who was born in colonial Burma in 1873. A farmer by profession, Thet learned meditation from teachers who believed that lay people, and not just monks, should practice meditation.

To make practice accessible, Maung Po Thet introduced a seven-day retreat for lay people. At the time, meditation typically involved longer periods of retreat.

Following his teacher’s approach, Ba Khin started teaching 10-day retreats in 1952. He later authorized students to carry his teaching abroad – to North America, Europe, Australia and India.

Globalization of the silent retreat

The most famous of these students was S.N. Goenka. Born in colonial Burma in 1924, Goenka was a wealthy businessman and leader of the Hindu community in Rangoon.

He initially sought out Ba Khin for relief from severe migraine headaches; Ba Khin was known as a healer. Despite reservations about Buddhist practice, Goenka enrolled in a 10-day retreat after experiencing relief from his headaches in an initial encounter with Ba Khin.

The experience proved transformative.

From 1969 until his death in 2013, Goenka devoted his life to spreading Ba Khin’s teachings globally while retaining his Hindu identity. Like his teacher, and his teacher’s teacher, Goenka taught practices of meditation that focused on the cultivation of continuous concentration on a single object of focus for sustained periods of time.

This was done through the observation of the breath, leading to a comprehensive awareness of bodily sensations in all postures and at all times when not sleeping.

Along with his wife, Ilaichidevi Goenka, he taught hundreds of 10-day retreats and trained assistants to facilitate retreats at roughly 200 meditation centers worldwide.

Millions have participated in these retreats, and many influential meditation teachers in India, Europe, Australia and North America first encountered meditation under Goenka’s guidance.

Roots of techno-mindfulness

One particularly consequential aspect of Goenka’s work was his use of audio and video recordings, beginning in the 1980s. In the face of increased demand for his courses, Goenka recorded teachings and instructions and established a highly structured retreat format.

This innovation allowed retreats to be facilitated worldwide in his absence, dramatically accelerating the global spread of the practice and foreshadowing later developments, such as meditation apps.

Goenka was also skilled at using the language of universalism to secularize Buddhist meditation, presenting himself as a committed non-Buddhist who nevertheless accessed its benefits.

This approach echoed that of Ba Khin, who spoke of teaching meditation without interfering in his students’ personal faith. Such rhetorical tactics proved crucial in making meditation accessible to global audiences.

Two lesser-known figures

Two other students of Ba Khin, rarely mentioned in historical accounts, also catalyzed the study of mindfulness in the U.S.: aerospace engineer Robert H. Hover and Leon E. Wright, a Black Christian theologian.

Robert H. Hover played a crucial role in initiating the scientific study of mindfulness and in the founding of the Insight Meditation Society in Massachusetts, one of the first U.S. centers dedicated to Southeast Asian Buddhist meditation.

Hover’s work helped bring mindfulness into mainstream medicine and society. Jon Kabat-Zinn, who created the Mindfulness-Based Stress Reduction, a program at the University of Massachusetts Medical School to help patients cope with chronic pain and stress, credits Hover as one of his primary teachers.

From the 1970s through the ’80s, Hover taught 10-day silent retreats across the U.S., Europe, India and Australia, helping to build communities of meditators through newsletters and informal networks.

Leon E. Wright
began teaching Ba Khin’s meditation techniques in the U.S. in the late 1950s, well before any of Ba Khin’s other students.

Wright’s work remained largely unknown because he was working primarily in the Black community. Until quite recently, very little attention has been paid to the role of Black practitioners in the modern history of Buddhism. Over the course of the past decade, however, scholars have begun to fill that gap.

The meaning of Leon Wright’s legacy for a modern Black meditation practitioner.

Wright taught Ba Khin’s techniques for decades at Howard University and organized silent retreats for the broader public. He was also a spiritual healer with interests in extrasensory perception and psychic experience.

His universalist teachings influenced generations of Black theologians. The Covenant Christian Community, a church in the Washington, D.C., area, continues to practice his meditation teachings in silence as well as gather for communal rituals on Sundays.

When people come to silent retreats today, they rarely learn about the networks and the individuals who made the teachings they receive possible to access, or whose work is seen and which voices may have been silenced.

An awareness of this history enriches the silence of a silent retreat.

La conversación docente: aprender a enseñar en secundaria

Source: The Conversation – (in Spanish) – By Eva Catalán, Editora de Educación, The Conversation

Tengo un amigo que cocina fenomenal. A menudo nos invita a probar en su casa elaboraciones exquisitas. Tiene un arsenal de hierbas, especias y productos de los que nunca había oído hablar y multitud de libros especializados en distintas técnicas culinarias. Pero no se le pueden pedir instrucciones para reproducir alguno de sus deliciosos platos. No es que sean secretas, o que no quiera darlas: es que no sabe explicar una receta paso a paso. Su nivel de virtuosismo culinario es tal, que cuando se trata de cuestiones básicas (¿esto va pelado o no? ¿cómo de pequeño se corta? ¿tiene que estar ya caliente el aceite? ¿a qué le llamamos “denso”?) a menudo se olvida de ellas, o las da por hecho, con resultados catastróficos.

Pasa exactamente lo mismo con la docencia. Dominar una materia no es para nada lo mismo que saber explicarla. ¿Preferimos a la profe de Literatura que se emociona con un verso, que domina todas las figuras estilísticas, y que puede pasar horas hablando sobre el amor cortés en la literatura medieval; o a la profe de Geografía que pone películas, propone juegos y escape rooms, nos lleva de excursión a museos y plantea debates en clase?

La pregunta es capciosa. Queremos ambas cosas, ¿no? Un “qué bien explica” con un “se nota que le importo”; un “cómo le gusta la materia” con un “disfruta dando clase”. ¿Cómo se consigue? La clave es la manera de formar a los futuros docentes.

En España, para primaria se acentúa la segunda parte (las herramientas pedagógicas, los conocimientos procedimentales), y para secundaria, sobre todo la primera (dominar la materia que se va a enseñar). Es un modelo “consecutivo”. Primero, el grado de Matemáticas, Física, Geografía o Lengua; después un máster de un año que concentra todo lo que tiene que ver con enseñarlo.

En el resto de Europa, el itinerario para llegar a dar clase en un instituto es a menudo “concurrente”: el futuro docente aprende simultáneamente el contenido y las estrategias para enseñarlo. Y en cuanto a la manera de estrenarse en la docencia, un 60 % de los centros cuenta con programas para la atención a profesores noveles, como mentorías, algo mucho más común en otros países.

¿Es suficiente este modelo consecutivo? A juzgar por los resultados de uno de los informes más completos que se realiza en el ámbito europeo sobre el bienestar y la calidad de la docencia, y como nos explican Javier M. Valle y Laura Vellaz Pérez de la Universidad Autónoma de Madrid, la respuesta a esta pregunta es no.

Y no es solo que los docentes de secundaria estén poco preparados en el aspecto práctico, y les toque aprender “sobre la marcha” cómo gestionar las emociones adolescentes, cuál es la mejor manera de que un concepto aterrice en sus mentes, o cómo alternar estrategias para evitar una clase rutinaria.

Es que en esos primeros años se establece la “identidad” del docente: cómo entiende su rol, con qué seguridad se enfrenta a los retos educativos y qué concepción tiene de su capacidad para enseñar. Una identidad frágil es más probable que desemboque en estrés laboral, síndrome de estar quemado y, eventualmente, abandono de la profesión.

Por eso los expertos recomiendan equilibrar mejor conocimientos sobre la materia y conocimientos sobre cómo enseñarla, un binomio básico no sólo para transmitir pasión por una asignatura, sino para desarrollar algo todavía más valioso para quien se dedica a la docencia: amor por la enseñanza, y las mejores habilidades para desarrollarlo.

Estas semanas hemos hablado también de modernizar la enseñanza de lenguas clásicas, cambiar nuestra mirada hacia las matemáticas, la oportunidad o necesidad de que sí se hable de política en los centros escolares, la cantidad y calidad de los conocimientos sobre democracia que se transmite en la escuela, las dinámicas del pasillo del instituto y cómo influyen en si se defiende o no a la víctima en una situación de acoso, y estrategias muy concretas para conseguir que los universitarios no falten a clase e integrar la inteligencia artificial sin perder capacidades cognitivas.

L’intelligence numérique peut aider à réduire les GES… et les aggraver. Voici comment jongler avec ce paradoxe

Source: The Conversation – in French – By Diane Gorcy, PhD candidate, Université du Québec à Montréal (UQAM)

La réduction des émissions de gaz à effet de serre nécessite une transition rapide vers des systèmes énergétiques bas carbone. On peut penser à l’énergie solaire, l’énergie éolienne ou encore la géothermie.


On peut aussi penser à l’intelligence numérique (IA, algorithmes, grande data, objets connectés). Elle offre des leviers puissants pour accélérer la transition vers des systèmes énergétiques bas carbone. Mais elle n’est pas neutre : sa production et son fonctionnement génèrent eux-mêmes des émissions et des impacts matériels.

La question de la responsabilité des innovations technologiques visant à accompagner la transition écologique est au coeur de mes recherches. Les technologies numériques peuvent-elles, paradoxalement, faire partie de la solution ? L’intelligence numérique ne risque-t-elle pas, au contraire, d’aggraver le problème lorsqu’elle a recours aux énergies fossiles ?

Lasagne d’intelligence numérique

L’intelligence numérique regroupe la science des données et l’intelligence artificielle, dans une approche dite « de la donnée à la décision ». Elle peut à cet égard fournir des données à partir desquelles de meilleures décisions seront prises, que ce soit en affaires, ou concernant la transition énergétique.

Prenons l’exemple d’Hydro-Québec qui, pour garantir la résilience et la fiabilité de son réseau électrique, doit s’adapter à plusieurs défis.

Une augmentation de la fréquence et de l’intensité des événements météo extrêmes – tempêtes, vents violents, verglas, feux de forêt, fortes précipitations – met à rude épreuve les infrastructures de production, transport et distribution.

En effet, les infrastructures sont de plus en plus vulnérables aux aléas climatiques, comme le verglas qui alourdit et fragilise les lignes électriques, ou les feux de forêt dans le nord qui menacent directement les installations.

L’adaptation du réseau énergétique aux changements climatiques repose sur une approche intégrée combinant des infrastructures plus efficaces, la diversification des sources d’énergie, l’optimisation de la consommation – et sa réduction – ainsi que l’amélioration de la flexibilité du réseau.

L’importance de la modélisation

C’est dans ce contexte que la modélisation devient un ingrédient indispensable de l’intelligence numérique. Les outils de modélisation du système énergétique jouent un rôle clé en permettant d’évaluer les différentes trajectoires vers la carboneutralité.

Par exemple, pour évaluer l’impact du transport routier à Montréal, on peut analyser les déplacements et les comportements des automobilistes sur une période donnée et extrapoler ces données sur l’année grâce à un logiciel de modélisation utilisant l’intelligence numérique.

Les modèles à choix discrets (Discrete Choice Models) sont des modèles statistiques qui décrivent et prédisent les décisions d’individus parmi un ensemble fini d’options, en fonction des caractéristiques des alternatives et des préférences des individus. Ainsi, l’intégration de ces données précises aux modèles permet non seulement d’évaluer le potentiel des nouvelles infrastructures, mais aussi de considérer des alternatives plus viables telles que les transports en commun, la marche, le vélo, ou encore le covoiturage.

Si la modélisation ne date pas d’hier, le recours à l’intelligence artificielle permet de réduire le temps de modélisation.

Expérimenter sans construire

Un autre exemple prometteur de l’usage de l’intelligence numérique dans la prise de décision est la modélisation par jumeau numérique.

Elle repose sur l’interaction entre le BIM (Building Information Modeling) et l’intelligence artificielle (IA). Elle consiste à créer une réplique virtuelle d’un bâtiment ou de toute autre infrastructure afin de simuler son comportement dans différentes conditions.

Cette approche permet d’optimiser la conception et les performances du bâtiment sans avoir recours à des matériaux physiques, réduisant ainsi la consommation de ressources. Connecté à des capteurs, le modèle reçoit des données en temps réel (par exemple : la température ou l’occupation d’un bâtiment).

L’IA analyse ces données pour simuler des scénarios, prédire des défaillances, ou optimiser la performance énergétique. Ce système permet ainsi de concevoir, gérer et améliorer un bâtiment sans intervention physique, réduisant les coûts et la consommation de ressources.

Les limites de l’intelligence numérique

Si les modèles mathématiques aident à identifier des scénarios viables pour la transition énergétique des secteurs du transport et des bâtiments, ils comportent leurs limites.

Les modèles utilisés dans ces analyses sont principalement de nature technico-économique. Autrement dit, ils évaluent ce qui est théoriquement réalisable en fonction des infrastructures et des coûts, mais ils ne tiennent pas toujours compte des obstacles sociaux, environnementaux ou politiques qui peuvent freiner leur mise en œuvre.

Par exemple, une solution identifiée comme optimale pour réduire les émissions de GES pourrait se heurter à des limites telles que le manque de volonté politique, la présence d’autres sources d’émissions non prises en compte, ou encore des impacts collatéraux sur la biodiversité et l’économie locale.

Une transition démocratique

La transition énergétique n’est pas seulement une question technologique, mais aussi politique et sociale. Par exemple, l’adoption de nouvelles normes sociales, comme la réduction de l’usage de l’automobile, doit être soutenue par des infrastructures facilitantes. Les pouvoirs publics ont la responsabilité d’accompagner ces changements.

Le numérique est un outil puissant, mais ce n’est pas une panacée pour affronter ce qui constitue sans doute l’un des plus grands défis de notre siècle. Pour que la recette fonctionne, l’intelligence numérique doit s’assurer de réunir tous les bons ingrédients.

Amy Adams y Jeremy Renner en una escena de _La llegada_. Paramount Pictures

Hace poco me di cuenta de que la melodía que acompaña el duelo de Agnes en Hamnet (en versión orquestal) es la misma que me pone los pelos de punta en La llegada. Me pareció fascinante y rebusqué algo más sobre ella. Descubrí que no solo la había escuchado en esas películas, sino en muchas otras (y en varias series). Y me hice muchas preguntas, porque si la pongo a solas en casa su sonido me retrotrae irremediablemente a la historia de Amy Adams y los extraterrestres (breve recordatorio para sugerir que, si no han visto La llegada, les recomiendo hacerlo en cuanto acaben de leer el boletín). Es decir, ¿tiene sentido reutilizar una pieza en un filme si su sonido está tan íntimamente ligado a otro? ¿O a tantos otros?

Por lo visto, sí. Ni Max Richter es el primero en hacerlo con “On the Nature of Daylight” (qué bella es en cada una de sus versiones) ni yo soy la primera en cuestionarlo. Juan José Pastor Comín decidió ponerse manos a la obra y explicar el origen de la pieza, sus usos y, también, qué implicaciones tiene que a mí, como espectadora, “ya me suene”.

Por cierto, una de las películas del año es la brasileña El agente secreto, con el país sudamericano buscando su segundo óscar consecutivo. Es un filme que, analizando el ambiente de la dictadura militar, resuena con el gobierno no tan lejano de Jair Bolsonaro.

Los bailes de los Bridgerton

Es algo que me fascina desde que empecé a ver (y leer) historias situadas en la Regencia: ¿cómo sabía todo el mundo qué pasos dar en esas danzas establecidas en las que los protagonistas suelen enamorarse?

Lara López explica en su artículo que la sociedad británica de la época tenía unas convenciones sociales muy definidas, mucho más rígidas que las de las adaptaciones audiovisuales. ¿Lo de conocer de pe a pa el baile al que las acaban de sacar? Parte de la formación de los jóvenes.

La ternura del macaco

Confesaré que yo entré al trapo de la historia de Punch completamente. No dejé de ver vídeos en tres días, preocupada por el destino del macaco y su peluche y a la vez consciente de que estaba antropomorfizando al animal. Pero no me importaba, me invadía la ternura viéndolo y observando su necesidad de sobrevivir socialmente.

Lo fascinante es que mi caso no fue nada extraño; la historia del mono generó tanto interés global que su construcción debía tener algún sentido narrativo, más allá de nuestra percepción de que era un niño desvalido. Y, efectivamente, Carlos José Monroy desgrana la serie de mecanismos que se han activado en nosotros al ver a Punch, algunos más obvios y otros más sutiles.

Lo que queda en Gaza

Está el mundo como para meterse bajo la colcha y no salir. Pero que la acumulación de conflictos no nos impida ver que algunos siguen activos. Uno de ellos es Gaza. Y aunque la importancia siempre la tienen las vidas perdidas y heridas durante los bombardeos israelíes, no es menos cierto que al destruir una tierra se desarman su presente, su futuro y también su pasado.

El patrimonio histórico y cultural de Gaza ha sido diezmado y el problema es que el organismo encargado de establecer las reglas para su protección, la UNESCO, no ha alzado la voz como sí lo hizo en otros conflictos. ¿Qué implicaciones tiene esto?

Un fallo artificial

La IA está aquí, siempre está aquí, ya nunca se va. Pero en ocasiones sus resultados no dejan de ser, como mínimo, algo chapuceros. Es lo que sucede cuando se erige en traductora pero es incapaz de trasladar a otro idioma los diferentes matices de una voz narrativa original. El trabajo de los humanos, que sopesa alternativas e intenta proporcionar un contexto parecido al de la lengua madre en la traducida, choca contra la uniformidad de las máquinas.

Me pregunto si se le ha ocurrido a alguien pasar por la IA las letras de Quevedo, Rawayana o Bad Bunny, y analizar si siguen teniendo su efecto original en otro idioma…
