Most of us have seen a nature documentary or two (or three) at some point in our lives, so it's a familiar format: sweeping majestic footage of impressively regal animals accompanied by reverently high-toned narration (preferably with a tony British accent). Underdogs, a new docuseries from National Geographic, takes a decidedly different and unconventional approach. Narrated by with hilarious irreverence by Ryan Reynolds, the five-part series highlights nature's less cool and majestic creatures: the outcasts and benchwarmers, more noteworthy for their "unconventional hygiene choices" and "unsavory courtship rituals." It's like The Suicide Squad or Thunderbolts*, except these creatures actually exist. Per the official premise, "Underdogs features a range of never-before-filmed scenes, including the first time a film crew has ever entered a special cave in New Zealand—a huge cavern that glows brighter than a bachelor pad under a black light thanks to the glowing butts of millions of mucus-coated grubs. All over the world, overlooked superstars like this are out there 24/7, giving it maximum effort and keeping the natural world in working order for all those showboating polar bears, sharks and gorillas." It's rated PG-13 thanks to the odd bit of scatalogical humor and shots of Nature Sexy Time Each of the five episodes is built around a specific genre. "Superheroes" highlights the surprising superpowers of the honey badger, pistol shrimp, and the invisible glass frog, among others, augmented with comic book graphics; "Sexy Beasts" focuses on bizarre mating habits and follows the format of a romantic advice column; "Terrible Parents" highlights nature's worst practices, following the outline of a parenting guide; "Total Grossout" is exactly what it sounds like; and "The Unusual Suspects" is a heist tale, documenting the supposed efforts of a macaque to put together the ultimate team of masters of deception and disguise (an inside man, a decoy, a fall guy, etc.).  Green Day even wrote and recorded a special theme song for the opening credits. Co-creators Mark Linfield and Vanessa Berlowitz of Wildstar Films are longtime producers of award-winning wildlife films, most notably Frozen Planet, Planet Earth and David Attenborough's Life of Mammals—you know, the kind of prestige nature documentaries that have become a mainstay for National Geographic and the BBC, among others. They're justly proud of that work, but this time around the duo wanted to try something different.

National Geographic/Karl Davies "There is a sense after awhile that you're playing the same animals to the same people, and the shows are starting to look the same and so is your audience," Linfield told Ars. "We thought, okay, how can we do something absolutely the opposite? We've gone through our careers collecting stories of these weird and crazy creatures that don't end up in the script because they're not big or sexy and they live under a rock. But they often have the best life histories and the craziest superpowers." Case in point: the velvet worm featured in the "Superheroes" episode, which creeps up on unsuspecting prey before squirting disgusting slime all over their food. (It's a handy defense mechanism, too, against predators like the wolf spider.) Once Linfield and Berlowitz decided to focus on nature's underdogs and to take a more humorous approach, Ryan Reynolds became their top choice for a narrator—the anti-Richard Attenborough. As luck would have it, the pair shared an agent with the mega-star. So even though they thought there was no way Reynolds would agree to the project, they put together a sizzle reel, complete with a "fake Canadian Ryan Reynolds sound-alike" doing the narration. Reynolds was on set when he received the reel, and loved it so much he recoded his own narration for the footage and sent it back. "From that moment he was in," said Linfield, and Wildstar Films worked closely with Reynolds and his company to develop the final series. "We've never worked that way on a series before, a joint collaboration from day one," Berlowitz admitted. But it worked: the end result strikes the perfect balance between scientific revelation and accurate natural history, and an edgy comic tone. That tone is quintessential Reynolds, and while he did mostly follow the script (which his team helped write), Linfield and Berlowitz admit there was also a fair amount of improvisation—not all of it PG-13.  "What we hadn't appreciated is that he's an incredible improv performer," said Berlowitz. "He can't help himself. He gets into character and starts riffing off [the footage]. There are some takes that we definitely couldn't use, that potentially would fit a slightly more Hulu audience."  Some of the ad-libs made it into the final episodes, however—like Reynolds describing an Aye-Aye as "if fear and panic had a baby and rolled it in dog hair"—even though it meant going back and doing a bit of recutting to get the new lines to fit.

National Geographic Despite their years of collective experience, Linfield and Berlowitz were initially skeptical when the crew told them about the pearl fish, which hides from predators in a sea cucumber's butt (along with many other species). "It had never been filmed so we said, 'You're going to have to prove it to us,'" said Berlowitz. "They came back with this fantastic, hilarious sequence of a pearl fish reverse parking [in a sea cucumber's anus)." The film crew experienced a few heart-pounding moments, most notably while filming the cliffside nests of barnacle geese for the "Terrible Parents" episode. A melting glacier caused a watery avalanche while the crew was filming the geese, and they had to quickly grab a few shots and run to safety. Less dramatic: cinematographer Tom Beldam had his smartphone stolen by a long-tailed macaque mere minutes after he finished capturing the animal on film. If all goes well and Underdogs finds its target audience, we may even get a follow-up. "We are slightly plowing new territory but the science is as true as it's ever been and the stories are good. That aspect of the natural history is still there," said Linfield. "I think what we really hope for is that people who don't normally watch natural history will watch it. If people have as much fun watching it as we had making it, then the metrics should be good enough for another season." Verdict: Underdogs is positively addictive; I binged all five episodes in a single day. (For his part, Reynolds said in a statement that he was thrilled to "finally watch a project of ours with my children. Technically they saw Deadpool and Wolverine but I don't think they absorbed much while covering their eyes and ears and screaming for two hours.") Underdogs premieres June 15, 2025, at 9 PM/8 PM Central on National Geographic (simulcast on ABC) and will be available for streaming on Disney+ and Hulu the following day.  You should watch it, if only to get that second season.

Google’s New Tech: This Isn’t a Photo - But It Is!

Despite claims from top names in AI, researchers argue that fundamental flaws in reasoning models mean bots aren’t on the verge of exceeding human smarts.

Larry Fabbroni is an architect, strategic advisor, and Chief Innovation Officer for Practice of Architecture. Throughout his career, he has led efforts to reform studio culture and innovate practice. He earned his MBA from the University of Chicago’s Booth School of Business. In 2017, as leaders in the AIA’s Young Architects Forum (YAF), we led the launch of the Practice Innovation Lab (PIL) and hosted a symposium that imagined new architectural practice models. At that time, we already felt that practice innovation was overdue in a profession that has not seen scaled disruption to its business model in over a century. Today, we are confident that there has never been a more critical time for the profession to embrace innovation. Redefining Innovation Henley Hall: Institute for Energy Efficiency by KieranTimberlake, Santa Barbara, California | KieranTimberlake’s research expertise creates value beyond a baseline labor model.  Currently, artificial intelligence dominates strategy conversations, but just as we saw back in 2017, larger patterns prompt calls for innovation. Talent attraction is increasingly challenging, disruptive technology continues to emerge, and actors from outside our industry show growing interest in the space. While incremental innovation has long been a part of the profession, relatively few firms have adopted new practices that create value beyond a baseline labor model. Firms such as KieranTimberlake have shown that research expertise can do this. MASS Design has pioneered a mission-driven approach. BIG has taken on the role of architect-as-developer. Snøhetta houses a product design division. We could continue to list great firms that have pushed the boundaries of practice, but they represent exceptions that have yet to be recognized as new standards. Indeed, the confluence of those factors that led to the original PIL continues to make the case that the time for scaled innovation is now. A Melting Iceberg: Incremental Changes Depleting the Profession Powerhouse Telemark by Snøhetta, Vestfold og Telemark, Norway | Photo by Ivar Kvaal | Snøhetta houses a product design division, innovatively presenting a alternative business model for firms.  One of the dangers of operating in a slow-moving industry is that change is difficult to detect and even more challenging to comprehend. If an iceberg loses 1% of mass per year, it’s tough to take notice, but the end result is catastrophic. This is what is happening to our profession. For newcomers, if it feels like there are increasingly more attractive opportunities elsewhere, that’s because there are. For seasoned professionals, if it feels like it’s become more challenging to maintain the same levels of prosperity, that’s because it has. Less(er) Talent In some ways, the shift towards companies recognizing “talent” as their most excellent resource has bewildered architects: we have always relied on talent. However, the patterns of talent leaving our profession are concerning. We say “feel” because there is no significant data. We spoke to Kendall A. Nicholson, Senior Director of Research at the Association of Collegiate Schools of Architecture (ACSA), who confirmed that aggregated data on graduate placement does not exist. So we inquired about what placement looks like at several programs around the country. Omar Khan, Head of the Carnegie Mellon University School of Architecture, informed us that approximately 90% of students pursue a minor to expand their horizons, and that in 2022, nearly one in three graduates entered the tech sector. Khan stated that these opportunities aren’t just student-driven — large innovative companies increasingly seek the value that graduates of architecture schools will provide. This increasing difficulty in capturing the talent that architecture schools are producing results in a shrinking and diluted talent pool. For a profession so reliant on human resources, this presents extreme risk. Pay Gaps In an increasingly expensive world, we are not able to compete for the best talent with emerging industries. It’s easy to understand why a popular career pivot for architects has become UX design. Designing user experience for websites pays significantly better than designing the same for the built environment. According to Glassdoor, 2023 entry-level UX designers earned an average of $78K, while the AIA salary calculator suggests architecture grads can expect to earn an average of $59 K. The talent we do attract into the profession often loses interest when they experience low pay and long hours, all while most firms lack clear paths and criteria for advancement or compensation increases. A Smaller Piece of the Pie Examining data in isolation, one might conclude that the profession continues to grow; the number of architects has increased substantially over the last century, and this trend has persisted in recent years. The problem with this growth is that the estimated share of the US GDP for Architectural Services has shrunk over time. This is not a manageable number to measure before 1999, when NCARB first aggregated local jurisdictional data. Due to limitations in industry economic data, we’re only showing data since 2011 for the purposes of this article. In that time, the number of architects has grown, the market size for services has grown, but the share those services represent as a portion of the US GDP has declined — by 15% if we use US Census data to almost 30% if we use industry research data (we used IbisWorld.com, however we found data that suggested a worse and others that offered a slightly better picture). To put it another way, architecture is a stagnant industry with a shrinking share of the economy. It’s challenging to examine this data and emerge feeling confident about the profession, but there is a silver lining. The biggest impediment to innovation for architects is not a lack of talent, but rather the business model. Design thinking has been widely adopted throughout the world as a key component of innovation processes; however, the problem is that we operate in the realm of professional services, which inherently is not well-suited to promoting innovation. Reliance on that formula is causing our iceberg to melt. The Tsunami: The AI Tidal Wave is Here The Rwanda Institute for Conservation Agriculture by MASS Design Group, Rwanda | MASS Design has pioneered a mission-driven approach that creates value beyond a baseline labor model.  As we confront the exodus of talent, it is easy for both firm owners and clients to imagine AI bringing efficiencies and replacing “CAD-monkeys” with machines. However, any firm that wants to operate — and win — as anything more than a low-cost provider will need a strategy to increase value, not just cut costs. AI is merely part of the toolbox required to confront a perfect storm of forces. Jobs will Disappear Goldman Sachs predicts that as much as 37% of our industry tasks will be replaced by AI. Many see this as a pathway to lower costs and increased profits. However, that is short-sighted. Markets will adjust quickly and demand lower costs for services; additional new value will need to be articulated and proven, and this will only happen through innovation. New Jobs will Emerge (but fewer of them) AI prophets often emphasize that technological innovation has historically led to net employment gains. Previous World Economic Forum estimates predicted losses of up to 85 million existing jobs worldwide, with parallel gains of as many as 97 million new jobs. However, these estimates were revised in the WEF 2023 Economic Outlook, which now anticipates a net loss of 14 million jobs. This stark outlook signals an even greater need for architects to become more innovative. The 2024 RIBA AI Report indicates that 41% of architecture firms were already utilizing AI, though current tools are indeed just the beginning. Marketing, business development and content creation will be standard areas of AI deployment moving forward. Still, revolutionary changes will come in how we learn, not only to use new tools, but also to collaborate with digital agents. How will this happen? We can theorize, but it is not possible to know for sure until it arrives, so we need to have a plan before we can see the tidal wave from land. The Alien Invasion: Outsiders Are Entering Our Orbit VIA 57 West by BIG – Bjarke Ingels Group, New York City, New York | BIG has pioneered a new model for practice by taking on the role of architect-as-developer. For years, we’ve heard cries that “architects gave away the role of master builder.” But how much did architects actually give, and how much was taken by innovative competition? This distinction is critical because the wagons are circling, and the AEC space has become ever more attractive to investors. Venture Capital and Private Equity Investment The numbers are often difficult to parse because architecture can impact so many verticals and does not operate as its own sector in the investment realm; however, the trends suggest a groundswell is underway. A 2023 McKinsey report shows that construction tech deals nearly doubled from 2019 to 2022, growing by 85%. At the same period, the number of deals increased by 30%, indicating that interest continues to grow. An increasing size of deals also suggests a maturity of the market. As interest in infrastructure investments has declined from its high in 2020, and along with real estate, has been blunted by high interest rates, institutional investors continue to see opportunities in the AEC space. Firm Acquisitions AEC firms that deliver predictable returns have proven to be attractive targets for PE firms. In the second quarter of 2024, private equity firms accounted for over one-third of AEC firm mergers and acquisitions. For M&A deals, the industry has seen an increase in attractiveness with expanded infrastructure spending as a catalyst. However, this interest can also be tied to the lack of innovation that has resulted in an industry ripe for consolidation. M&A orchestrators generate large amounts of profit by streamlining operations, eliminating redundancies, and then stamping out competition. An entire community has been built around this, with AEC Advisors hosting an annual “Private Equity Summit” that brings together CEOs of AEC firms with PE investors. Startups As an extension of the growing interest from venture capital in the space, there is an upward trend in the AEC space being targeted for disruption by entrepreneurs who see an industry that represents a significant portion of the global GDP. AEC Works, a project of e-verse that catalogs AEC startups and investors, lists nearly 800 startups from around the world, with almost 200 identified as “architecture-focused.” The signal is clear: startups are looking to figure out how to do what you do cheaper, better, or perhaps both. Combining this environment with depleted talent pools, a declining share of GDP, and revolutionary technology, it is a correct response to be alarmed. Significant change is inevitable. It is time for architects to see the same opportunities that investors and entrepreneurs see, and learn to navigate within these spaces. The Great Opportunity Throughout history, new actors have enjoyed a “leap-frog” effect and been able to surpass established incumbents to reshape industries, markets and economies. From climate change to pandemic ripple effects, to the housing crisis, to generational shifts in the workforce, there are many forces that directly impact the work of architects and call for innovation. The need for new ways of designing and delivering different components of the built environment is ever-present and will be solved by teams that either include — and might be led by — architects, or those that do not. Most end users will only care if the resulting product is superior. This time of tension is indeed a time of great opportunity. Architects who embrace innovation in pursuing new iterations of our dated business models may actually achieve what many of us have dreamed of from the start: to leave a positive mark on the world. We think the future of the profession depends on it.

Debate about whether artificial intelligence can replicate the intellectual labor of doctors, lawyers, or PhDs forgoes a deeper concern that’s looming: Entire companies—not just individual jobs—may be rendered obsolete by the accelerating pace of AI adoption. Reports suggesting OpenAI will charge $20,000 per month for agents trained at a PhD level spun up the ongoing debate about whose job is safe from AI and whose job is not. “I’ve not seen it be that impressive yet, but it’s likely not far off,” James Villarrubia, head of digital innovation and AI at NASA CAS, told me. Sean McGregor, the founder of Responsible AI Collaborative who earned a PhD in computer science, pointed out how many jobs are about more than just a set of skills: “Current AI technology is not sufficiently robust to allow unsupervised control of hazardous chemistry equipment, human experimentation, or other domains where human PhDs are currently required.” The big reason I polled the audience on this one was because I wanted to broaden my perspective on what jobs would be eliminated. Instead, it changed my perspective. AI needs to outperform the system, not the role Suzanne Rabicoff, founder of the human agency think tank and fractional practice, The Pie Grower, gave me some reading assignments from her work, instead of a quote. Her work showed me that these times are unprecedented. But something clicked in my brain when she said in her writing that she liked the angle of more efficient companies rising instead of jobs being replaced at companies with a lot of tech and human capital debt. Her response to that statement? “Exactly my bet.”  Sure, this is the first time that a robot is doing the homework for some college students. However, there is more precedent for robots moving market share than for replacing the same job function across a sector. Fortune 500 companies—especially those bloated with legacy processes and redundant labor—are always vulnerable to decline as newer, more nimble competitors rise. And not because any single job is replaced, but because the foundational economics of their business models no longer hold. AI doesn’t need to outperform every employee to render an enterprise obsolete. It only needs to outperform the system. Case study: The auto industry Take, for example, the decline of American car manufacturers in the late 20th century. In the 1950s, American automakers had a stranglehold on the car industry, not unlike today’s tech giants. In 1950, the U.S. produced about 75% of the world’s cars. But in the 1970s, Japanese automakers pioneered the use of robotics in auto manufacturing. These companies produced higher-quality vehicles at great value thanks to leaner operations that were also more precise. Firms like GM struggled to keep up, burdened by outdated factories and excessive human capital costs—including bloated pensions. The seismic shift in the decades to follow paints a picture of what could be in store for large companies now. In 1960, the U.S. produced about 48% of the world’s cars, while Japan accounted for just 5%. By 1980, Japan had captured around 29% of the market, while the U.S. had fallen to 23%. Today’s AI shakeup could look similar. Decades from now, we could look at Apple similarly to how we look at Ford now. AI startups with more agile structures are poised to eat market share. On top of that, startups can focus on solving specialized problems, sharpening their competitive edge. Will your company shrivel and die? The fallout has already begun. Gartner surveyed organizations in late 2023, finding that about half were developing their own AI tools. By the end of 2024, that dropped to 20%. As hype around generative AI cools, Gartner notes that many chief information officers are instead using outside vendors—either large language model providers or traditional software sellers with AI-enhanced offerings. In 2024, AI startups received nearly half of the $209 billion in global venture funding. If only 20% of legacy organizations currently feel confident competing with these upstarts, how many will feel that confidence as these startups mature? While headlines continue to fixate on whether AI can match PhD-level expertise, the deeper risk remains largely unspoken: Giant companies will shrivel and some may die. And when they do, your job is at risk whether you greet customers at the front desk or hold a PhD in an engineering discipline. But there are ways to stay afloat. One of the most impactful pieces of advice I ever received came from Jonathan Rosenberg, former SVP of products at Google and current advisor to Alphabet, when I visited the company’s campus in college. “You can’t just be great at what you do, you have to catch a great wave. Early people think it’s about the company, then the job, then the industry. It’s actually industry, company, job…” So, how do you catch the AI wave? Ankur Patel, CEO of Multimodal, advises workers to learn how to do their current jobs using AI tools that enhance productivity. He also notes that soft skills—mobilizing people, building relationships, leading teams—will become increasingly valuable as AI takes over more technical or routine tasks. “You can’t have AI be a group leader or team leader, right? I just don’t see that happening, even in the next generation forward,” Patel said. “So I think that’s a huge opportunity…to grow and learn from.” The bottom line is this: Even if the AI wave doesn’t replace you, it may replace the place you work. Will you get hit by the AI wave—or will you catch it? George Kailas is CEO of Prospero.ai.

June 2, 20253 min readThe World Isn’t Ready for the Mental Health Toll of Extreme HeatTemperatures are rising, and so are mental health risksBy Madhusree Mukerjee edited by Dean VisserA man walks with an umbrella to protect himself from the heat as a yellow alert is issued by the UK Health Security Agency (UKHSA) due to increasing temperatures in London, United Kingdom on June 25, 2024. Rasid Necati Aslim/Anadolu via Getty ImagesThe coming summer is forecast to be a scorcher across the U.S. And climate scientists predict that at least one of the next five years will beat 2024 as the hottest year ever recorded globally. As heat waves are getting more intense and prolonged, their effect on the mind and body are also becoming more dire. Children and older people, as well as those who work outdoors, are most at risk. So are those with mental health disorders.Heat waves are the single highest cause of weather-related deaths in the U.S., where an estimated 1,300 fatalities from heat stroke and other temperature-related complications occur every year. Even those who survive a period of extreme heat may suffer serious neurological or other mental-health-related disorders.A new study published in Current Environmental Health Reports finds that the world is startlingly unprepared to deal with the mental health consequences of climate change. Of 83 action plans for heat-related health problems that were reviewed for the study, fewer than a third acknowledged the mental health effects of extreme or prolonged high temperatures. And only a fifth of these plans outlined specific actions to deal with contingencies such as increased hospitalizations for mental health disorders.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

If a person doesn’t drink enough water when the weather is hot and dry, the body becomes dehydrated, the blood thickens, and the heart may not be able to pump enough oxygen to the brain. Additionally, the human brain burns up 20 percent of the body’s energy and therefore needs to dissipate heat efficiently. In hot and humid conditions, sweating cannot cool the body and brain enough. This can lead to heat exhaustion, which has symptoms such as weakness, dizziness and headaches and, in extreme cases, heat stroke—which can then trigger delirium and loss of consciousness. A significant fraction of heat stroke survivors suffer neurological complications.Exposure to extreme heat can also increase the risk of suicide and can worsen schizophrenia, epilepsy, anxiety, depression, substance use disorder, neurodegenerative disorders (such as Alzheimer’s disease) and negative emotions such as fear and anger. It may worsen sleep, which, in turn, can increase fatigue and impair cognition. Alcohol and recreational drugs, as well as certain medications used to treat mental illness, such as antidepressants, tranquilizers and antipsychotics, also appear to increase mental health vulnerability to heat.Studies find an increased risk of suicide and epileptic seizures during heat waves, as well as an increase in hospitalizations and emergency-room visits for mental health disorders. Heat can also disorient thinking, making people slow to realize that they need to seek shelter or help.Who is most at risk?The most vulnerable are those with existing mental health disorders. Disturbingly, prolonged heat waves also appear to worsen the risk among young children—and even the unborn—of developing mental health ailments in the future. Older people may also be particularly affected, such as by accelerated dementia and Alzheimer’s.At particular risk are vast populations around the world who live without air-conditioning, including poor or homeless people and those who work outdoors, such as on farms.What can be done?The authors of the new Current Environmental Health Reports study point to interventions at several levels to help communities and individuals most at risk of climate mental health impacts. These can include public awareness campaigns, such as warning people about the mental health risk of consuming alcohol or other drugs during heat waves. Other interventions include establishing community cooling shelters for heat emergencies and increasing monitoring of mental health patients during heat waves. Extreme heat is here to stay, at least for the foreseeable future. We need to prepare people and communities to reduce the risk of mental health emergencies.IF YOU NEED HELPIf you or someone you know is struggling or having thoughts of suicide, help is available.
