  • Negative thermal expansion alloy to enable stable lenses to hunt for exoplanets

    02 Jul 2025

    Company Allvar working with NASA on NTE space telescope optics; other applications are possible.

    A new material that shrinks when it is heated and expands when it is cooled could help enable the ultra-stable space telescopes that future NASA missions require to search for habitable worlds; planets beyond our solar system (exoplanets) that could support life. Over the past two decades, scientists have developed ways to detect atmospheres on exoplanets by closely observing stars through advanced telescopes. As light passes through a planet’s atmosphere or is reflected or emitted from a planet’s surface, telescopes can measure the intensity and spectra of the light, and can detect various shifts in the light caused by gases in the planetary atmosphere.

    To successfully detect habitable exoplanets, NASA’s future Habitable Worlds Observatory (HWO) will need a contrast ratio of one to one billion. This in turn will require a telescope that is 1,000 times more stable than state-of-the-art space-based observatories like NASA’s James Webb Space Telescope and its forthcoming Nancy Grace Roman Space Telescope. New sensors, system architectures, and materials must be integrated and work in concert for future mission success.

    A team from Allvar Alloys, College Station, TX, and Syracuse, NY, is collaborating with NASA’s Marshall Space Flight Center and NASA’s Jet Propulsion Laboratory to demonstrate how integration of a new material with “unique negative thermal expansion characteristics” can help enable ultra-stable telescope structures.

    The materials currently used for telescope mirrors and struts have drastically improved the dimensional stability of the great observatories like Webb and Roman, but as indicated in the Decadal Survey on Astronomy and Astrophysics 2020 developed by the National Academies of Sciences, Engineering, and Medicine, they still fall short of the 10 picometer level stability over several hours that will be required for the HWO.

    Funding from NASA and other sources has enabled this material to transition from the laboratory to the commercial scale. Allvar received NASA Small Business Innovative Research funding to scale and integrate a new alloy material into telescope structure demonstrations for potential use on future NASA missions like the Habitable Worlds Observatory.

    This alloy shrinks when heated and expands when cooled – a property known as negative thermal expansion. For example, Allvar’s Alloy 30 exhibits a -30 ppm/°C coefficient of thermal expansion at room temperature. This means that a 1-meter long piece of this NTE alloy will shrink 0.003 mm for every 1 °C increase in temperature. In contrast, aluminum expands at +23 ppm/°C.

    Because it shrinks when other materials expand, Allvar Alloy 30 can be used to strategically compensate for the expansion and contraction of other materials. The alloy’s unique NTE property and lack of moisture expansion could enable optic designers to address the stability needs of future telescope structures.

    Thermal stability ‘improved up to 200 times’

    Calculations have indicated that integrating Alloy 30 into certain telescope designs could improve thermal stability up to 200 times compared to only using traditional materials like aluminum, titanium, carbon fiber reinforced polymers, and the nickel–iron alloy, Invar.

    To demonstrate that negative thermal expansion alloys can enable ultra-stable structures, the Allvar team developed a hexapod structure to separate two mirrors made of a commercially-available glass ceramic material with ultra-low thermal expansion properties. Invar was bonded to the mirrors and flexures made of Ti6Al4V—a titanium alloy commonly used in aerospace applications—were attached to the Invar.

    To compensate for the positive CTEs of the Invar and Ti6Al4V components, an NTE Allvar Alloy 30 tube was used between the Ti6Al4V flexures to create the struts separating the two mirrors. The natural positive thermal expansion of the Invar and Ti6Al4V components is offset by the negative thermal expansion of the NTE alloy struts, resulting in a structure with an effective zero thermal expansion.

    The stability of the structure was evaluated at the University of Florida Institute for High Energy Physics and Astrophysics. The hexapod structure exhibited stability well below the 100 pm/√Hz target and achieved 11 pm/√Hz. This first iteration is close to the 10 pm stability required for the HWO. A paper and presentation made at the August 2021 Society of Photo-Optical Instrumentation Engineers conference provides details about this analysis.

    Furthermore, a series of tests run by NASA Marshall showed that the ultra-stable struts were able to achieve a near-zero thermal expansion that matched the mirrors in the above analysis. This result translates into less than a 5 nm root mean square change in the mirror’s shape across a 28K temperature change.

    Beyond ultra-stable structures, the NTE alloy technology has enabled enhanced passive thermal switch performance and has been used to remove the detrimental effects of temperature changes on bolted joints and infrared optics. These applications could impact technologies used in other NASA missions. For example, these new alloys have been integrated into the cryogenic sub-assembly of Roman’s coronagraph technology demonstration.

  • ‘Dora the Explorer’ live-action movie premieres on Nickleodeon and Paramount+

    ‘Dora the Explorer’ live-action movie premieres on Nickleodeon and Paramount+

    Millions of children in more than 150 countries have watched a 7-year-old Latina with her trademark purple backpack take friends on fun television adventures.

    Now, Nickelodeon’s animated series “Dora the Explorer” is celebrating its 25th anniversary with a live-action movie, premiering on Nickelodeon and Paramount+ on Wednesday, ahead of the July 4 holiday weekend.

    “Dora and the Search for Sol Dorado” tells the story of 16-year-old Dora (played by Samantha Lorraine) who is budding into a skilled treasure hunter.

    The movie follows Dora and her friend Diego (Jacob Rodriguez) as they trek through a jungle to find an ancient treasure that could grant a magical wish.

    This teenage version of Dora, Mexican director Alberto Belli says, is like Indiana Jones and Lara Croft, but with a spunky “lo hicimos” (“We did it”) attitude that makes her uniquely Latina.

    But according to Belli, Dora is more interested in the adventure because it can help her figure out who she is and what other people are like.

    Developing this larger sense of finding her place became a guiding theme for the movie.

    “When you’re taking a cartoon character into a live action, you need to go a little bit deeper. So we tried to create some more problems,” Belli said in an interview, accompanied by actress Samantha Lorraine. “She (Dora) loses her bag, which is a spoiler, but it’s also in the trailer. So now she needs to find who she really is. And I think right now, more than ever, people feel a little lost.”

    Dora’s backpack typically contains specific items, including a map, which she will need on her adventures. And Belli says that when “you don’t know exactly where you need to go,” you have to look inside yourself to figure it out.

    Lorraine says that “Sol Dorado” (“Golden Sun”) is more about finding an internal space — “who you are as a person.”

    “When she (Dora) finds Sol Dorado, to me, it was this full circle moment that we had finally finished this character arc,” the young actress said.

    Many iconic action-adventure characters “usually go and explore someone else’s culture. They never explore their own culture,” Belli said. “What’s really exciting about Dora is she loves history. She’s exploring her own culture.”

    The movie incorporates Indigenous Latino traditions that influence Dora’s identity.

    One such tradition was based on “ayllu,” which is the Andean way of organizing communities to support each other through shared land, resources and responsibilities.

    “When it comes to ayllu, friendship and connection is so important, and I think Dora is the epitome of that. She’s the connection through most cultures of the world,” Lorraine said, adding that “Dora the Explorer” has been translated into more than 30 languages.

    Belli said that they had an expert on set to guide them through different Indigenous traditions, including quipus, which are knotted cords that were used by the Incas to record information.

    They also had two consultants to work on pronunciation for when Dora had to speak in Quechua, which is an Indigenous language spoken by people in parts of Perú, Bolivia and Ecuador.

    Lorraine, who identifies as Cuban American, says that playing Dora was a privilege because she offers many Latino children visibility.

    “I kept thinking to myself, what do I want my little cousins to see when they watch this movie?,” she said.

    Lorraine wants “Dora and the Search for Sol Dorado” to help viewers — regardless of their age — keep their sense of adventure and curiosity alive.

    Dora has “always been part of pop culture,” Belli said, adding that he has a 5-year-old who’s a big fan.

    “When I got the job, he got more excited than I did,” the director said with a laugh. “What I love about Dora is she’s a positive influence in people; she teaches you how to be positive, energetic and adventurous — and at the same time she teaches Spanish in a fun way, which I think is very cool.”

  • Any animals standing within 1,500km of the impact would have been instantly vaporised: 10 terrible times to be alive

    Any animals standing within 1,500km of the impact would have been instantly vaporised: 10 terrible times to be alive

    It’s easy to think, given the current geopolitical state of the world, that we’re living through an especially terrible time. Add to that the possibility that Earth may be undergoing its sixth mass extinction and it’s perhaps justified to conclude that the 21st century is the worst time period ever.

    While this may be the case by some definitions, there’s no escaping the fact that we, as a species, have it better than our ancestors and those that came before them ever did. For the majority of Earth’s history, life has simply been a matter of survival. Let’s take a look at some times when staying alive was particularly difficult…

    10 terrible times to be alive

    The time the ocean lost almost all its oxygen

    The Middle Cretaceous may have been a particularly prosperous time for life on land, but under the waves a geochemical storm was slowly brewing – one that would eventually rob the oceans of oxygen and cause the extinction of more than 25% of marine invertebrates, as well as one of the most iconic marine reptiles of the Mesozoic Era, ichthyosaurs.

    This calamitous event is known as the Cenomanian-Turonian boundary event and it’s widely considered to be the most recent, truly global oceanic anoxia event in Earth’s history. It happened roughly 94 million years ago following the eruption of a series of underwater volcanoes in the newly formed Atlantic Ocean. 

    These eruptions released nearly 4 million cubic kilometres of lava (enough to fill the Mediterranean Sea) and enough CO₂ to raise global temperatures by more than 5°C. At the equator during this time, water temperatures exceeded 42°C, which is warmer than those typically experienced in a hot tub! Even water temperatures at the poles were a balmy 20°C.

    This period also witnessed massive plankton blooms – caused by an increase in dissolved nutrients as a result of increased rock weathering. When this plankton died it was eaten by bacteria, which consumed lots of dissolved oxygen from the water column. 

    For more than half-a-million-years, the deeper levels of the world’s oceans were devoid of oxygen, making them inhospitable to almost all forms of life.

    The time a tsunami (may have) submerged part of Europe

    Doggerland: Credit Caroline May

    Not too long ago (around 10,000 years), a land bridge known as Doggerland connected the east coast of the UK to the Netherlands, northwest Germany, and the Danish peninsula of Jutland.

    This lowland area was once inhabited by mammoths, cave lions, sabretooth tigers, and several other iconic ice age animals. It was also home to roaming bands of hunter gatherers, as evidenced by the discovery of several artifacts dredged up during trawling missions in the North Sea – the most famous being a 20cm-long harpoon carved from a deer’s antler.

    For our ancestors, Doggerland provided some of the continent’s richest hunting grounds, not to mention a bountiful supply of freshwater. However, by 8,000 years ago it had completely disappeared beneath the waves.

    What happened to Doggerland is controversial. Some claim it was suddenly submerged by a tsunami triggered by an underwater landslide just off the coast of Norway 8,200 years ago, while others think it was slowly consumed by rising sea levels.

    In reality, it was likely a combination of both. A 2020 study put forward evidence to suggest that Doggerland had already reduced dramatically in size (as a result of rising sea levels) by the time the tsunami hit. Regardless, anyone who lived in Doggerland 8,200 years ago would have probably given everything they had to be anywhere else.

    The time when insects were massive

    Arthropleura

    If insects make your skin crawl, then the Carboniferous Period (359 to 299 million years ago) would probably be your idea of hell on Earth. This is a period often referred to as the ‘Age of Giant Insects’, and for good reason – during the Carboniferous, Earth was ruled by bugs many times bigger than any alive today.

    The 2m-long, double-duvet sized Arthropleura was the largest of the Carboniferous’ giant bugs. It’s distantly related to today’s millipedes and like its living relatives it also subsisted on a diet of decaying plants and animals. There was also a dragonfly-like insect known as Meganeura that, with a 75cm-wide wingspan, was roughly the same size as a sparrowhawk.

    It’s often said that bugs achieved gigantism during the Carboniferous as a result of increased levels of oxygen in the atmosphere, and while this may be true to some degree it’s more likely they grew so large in response to a lack of competition from vertebrates. At this time, vertebrates were still relatively small and largely confined to environments close to water.

    As a group, vertebrates were dwarfed and outnumbered by bugs during the Carboniferous, but fast forward a few million years to the Permian Period (299 to 252 million years ago) and they soon emerged as the most dominant forms of life on land. The Permian was a period of great diversification for vertebrates. However, while it may have been evolutionary prosperous for some groups, it ended in disaster for others – but more on that later.

    The time fungi towered over everything else

    The first kind of life to really gain a foothold on land wasn’t plants, but fungi. The first fungi were relatively small, but they soon paved the way for giants such as Prototaxites. This tree-like organism lived roughly 400 million years ago and formed huge spires that measured up to 1m in diameter and reached heights of more than 8m.

    It’s unclear exactly what Prototaxites was; it may have been a fungus, or it may belong to a long-lost group of lichens. Whatever its affinities, Prototaxites was by far the largest land-dwelling organism of its time and towered over everything that attempted to grow in its shadows.

    Prototaxites, along with many other early types of fungi, are thought to have been saprotrophic. This is a process whereby fungi release digestive enzymes that break down organic matter, allowing them to extract nutrients from the material they’re growing on. These enzymes are so powerful that, over time, they can break down rock and form fertile soils. It’s this process that researchers think prepared Earth’s surface for the vascular plants that emerged during Prototaxites’ reign

    So, why was this a particularly terrible time to be alive? Well, without large networks of plants producing oxygen, levels of it in the atmosphere were a lot lower than they are today. There was also very little to eat, especially if you weren’t a fan of mushrooms.

    The time a pandemic lasted 18 million years

    From the Early Oligocene (33 million years ago) to the Early Miocene (15 million years ago), an ancient virus known as ERV-Fc plagued dozens of different species of mammals, from dolphins to great apes. The inactive fragments of this virus still live on in many mammals today, including us, and it’s the study of these fragments that have allowed scientists to learn more about it.

    ERV-Fc is what’s known as an endogenous retrovirus – a type of virus that infects cells and inserts itself into its host’s DNA. When this happens in reproductive cells, the viral sequence can be passed from parent to offspring. ERVs are very common in the genomes of vertebrates and are estimated to make up nearly 8% of our own genome.

    A 2016 study revealed that ERV-Fc independently infected many different groups of mammals, rather than a single shared ancestor. This study also found evidence to suggest that the virus jumped species more than 20 times over the course of an 18-million-year-long pandemic that spread across all continents besides Australia and Antarctica.

    It’s unclear exactly how deadly ERV-Fc was, but based on its structure it’s understood to be part of a group of viruses known as gammaretroviruses. Today, this group includes the murine leukemia virus (MuLV) in mice and feline leukemia virus in cats (FeLV), both of which are known to cause cancer.

    The time when Earth was ruled by giants

    The blue whale (Balaenoptera musculus) may be the largest animal to have ever lived, but on average animals alive today are a lot smaller than those that lived during parts of prehistory.

    The Late Jurassic (162 to 143 million years ago) is a period that’s particularly renowned for its giants. It’s often referred to as the ‘Golden Age’ of not only dinosaurs, but pterosaurs and marine reptiles too – wherever you lived during the Late Jurassic, be it on land, in the sky, or in the oceans, a giant, hungry reptile was never too far away.

    Some of the largest dinosaurs of the time lived in North America and are known from fossils uncovered from the world famous Morrison Formation. This expansive, dinosaur-bearing rock formation has yielded more than 10 different meat-eating theropods, all of them large enough to hunt human-sized animals.

    The king amongst these theropods wasn’t T.rex (that particular species appeared in the Late Cretaceous around 70 million years later), rather Allosaurus – a smaller but arguably more belligerent predator that’s thought to have hunted in packs and been capable of bringing down giant, long-necked dinosaurs known as sauropods. These plant-eating sauropods would have been deadly too, crushing anything unlucky enough to get caught under their feet. 

    The Late Jurassic may have been a great time to be a giant, but for any animal smaller than a Volkswagen Beetle it would have been particularly terrible.

    The time it rained for 2 million years

    The Triassic (252 to 201 million years ago) is widely regarded as one of the hottest and driest periods in Earth’s history. However, during this 51-million-year-long period, there was a 2-million-year-long episode when it rained pretty much non-stop.

    This is known as the Carnian Pluvial Episode (CPE) and it started roughly 234 million years ago. It’s evidenced by thick layers of river rocks, sediments from giant lakes, and evidence of coal swamps sandwiched in between layers of drier rocks more traditionally associated with the Triassic, such as red sandstones. These peculiar layers are signs of increased rainfall and they’re found all over the world, hinting at a global climate shift.

    Some estimates suggest that rainfall quadrupled over this period and as much as 1,400mm of rain was dumped every year – that’s how much a temperate rainforest gets today, but this would have fallen across the entire supercontinent of Pangea!

    This massive amount of rain had a profound impact on the animals that lived during the Middle Triassic, particularly the dinosaurs. In rocks dated to the start of the CPE, dinosaurs make up just 5% of the fossils of terrestrial vertebrates. In rocks dated to the end of this episode, they comprise more than 90%.

    The dinosaurs’ distant relatives, the crocodile-line archosaurs, didn’t relish the rain quite as much, which is ironic considering the watery habitats their descendants live in today. They experienced huge losses at this time and never again reached the diversity they had during the Early Triassic.

    The time an asteroid destroyed a dynasty overnight

    Since the emergence of animals some 800 million years ago, Earth has witnessed five major mass extinctions – together these are known as the ‘Big Five’. 

    The event that wiped out the dinosaurs 66 million years ago wasn’t the most destructive of the five – that title goes to an event discussed later – but it is the one that wiped out entire families of animals and plants in a matter of days, rather than over the course of millennia.

    This event, known as the K-Pg mass extinction, was caused by the impact of a giant, 15km-wide asteroid that made landfall in what is now the Yucatán Peninsula in Mexico. Based on fish bones found in the impact’s ejecta layer, it’s thought the impact may have taken place during spring.

    The effects of the impact were catastrophic; any animals (or plants) standing within 1,500km at the time of the impact would have been instantly vaporised. Those standing further away weren’t exactly safe and would have arguably faced an even more painful death, being melted by firestorms, catapulted by hurricane-force winds, crushed by blazing debris, or simply suffocated by the poisonous air.

    It’s estimated that the energy released during the impact was equivalent to 10 billion Hiroshima bombs.

    There were some plucky animals that survived this ‘worst day ever’, including our mammalian ancestors, but when the fires finally burnt themselves out and the dust clouds settled, as many as 75% of species on Earth had disappeared.

    The time when humans were prey

    We may be firmly at the top of the food chain today, but for the majority of our existence we were prey for many larger, toothier predators. 

    While they’re not considered a member of our genus (Homo), australopithecines are often referred to as ‘humans’, or at least incredibly close relatives. Later undisputed human species include Homo erectusHomo neanderthalensis, and – of course – Homo sapiens. These early humans lived alongside some of prehistory’s most terrifying animals, including sabretooth tigers, giant short-faced bears, and baby-eating eagles.

    There’s lots of evidence to suggest that early humans were prey for such animals. The most famous example is the 2.8-million-year-old Taung Child – a fossilised skull of a young Australopithecus africanus that bears a puncture wound in each of its eye sockets. These wounds match those made by the talons of a crowned eagle, suggesting the child was killed and carried off by an airborne predator.

    There’s gruesome evidence of our distant relatives being hunted by big cats too – the remains of a female Paranthropus robustus found in a cave in South Africa show signs of having been bitten and gnawed on by a leopard.

    As humans got larger and, crucially, smarter, it’s likely that more and more predators stopped viewing them as prey. That said, we shouldn’t get too complacent; even today there are animals that, if hungry enough, will target humans, such as tigers, polar bears, and crocodiles.

    The time nearly everything died

    Known fittingly as the ‘Great Dying’, the End-Permian mass extinction is the third of Earth’s ‘Big Five’ and – in terms of how many species were wiped out as a result – the most destructive. This era-defining event almost ended life on Earth entirely and by some estimations may have consigned as many as 90% of species to extinction!

    The impacts of this event were destructive on land, but they were truly cataclysmic in the oceans where entire ecosystems collapsed, never to be seen again. Some of the most diverse groups in preceding periods, such as eurypterids, trilobites, and blastoids, were completely eradicated during this event. Others lost more than 95% of their species (e.g. brachiopods, crinoids, and ammonites) and only narrowly made it through to the following period, the Triassic.

    The ‘Great Dying’ is widely considered to have been caused by the eruption of a huge volcanic system that lay under what is now Siberia, Russia. This eruption released huge amounts of greenhouse gases into the atmosphere, which elevated global temperatures and acidified the planet’s oceans. This injection of greenhouse gases raised levels of CO₂ in the atmosphere from 400 ppm to 2,500 ppm. To put that into perspective, current CO₂ levels measure ~430 ppm.

    The ‘Great Dying’ didn’t happen overnight like the extinction event that claimed the lives of the dinosaurs; instead it lasted for nearly 50,000 years and may have taken place in several distinct pulses. Staying alive during this time would have been particularly difficult, though it wasn’t impossible and our existence today is proof that some resilient animals made it through.

  • Wildfire kills two people in Spain amid European heat wave

    Wildfire kills two people in Spain amid European heat wave

    BARCELONA, Spain — A relentless European heat wave helped fuel a deadly wildfire in Spain while the European Union presented plans to reduce greenhouse gas emissions under scorching temperatures on Wednesday.

    The blaze that broke out late on Tuesday created an enormous thick plume of ash and smoke that reached 14,000 meters (45,000 feet) of altitude, making it the largest registered by firefighters in Catalonia, a northeastern region of Spain.

    Two farmers were killed while apparently trying to flee in a vehicle, local authorities said Wednesday.

    Firefighters said that the fire spread at 28 kph (17 mph) at one point as it consumed 6,500 hectares (16,000 acres) mostly of grain fields, making it one of the fastest fires registered in Europe.

    “Wildfires today are not like they were before,” Salvador Illa, the regional president of Catalonia, said. “These are extremely dangerous. From the very first moment, it was considered to be beyond the capacity of extinction. I mean that not even with two or three times the number of firefighters, they have told me, it would have been possible to put out.”

    Firefighters credited a rainstorm later on Tuesday for having “quickly changed the situation and helped speed up getting the fire stabilized.”

    Two of the 500 firefighters who deployed needed treatment at a local hospital for their injuries. Some 14,000 residents were ordered to stay indoors for several hours on Tuesday night.

    More hot weather is expected on Wednesday with temperatures in the Lleida region forecast to reach a high of 39 C (102 F).

    The European Center for Medium-Range Weather Forecasts said that it was closely monitoring the abnormally hot temperatures. Weather experts link the heat wave to climate change.

    As much of Europe was scorched by torrid weather, the European Commission unveiled proposals to reduce emissions by 90% by 2040 as the 27-nation bloc aims to be fully carbon-neutral by 2050.

    “We are finally here on a very hot day, and some would call that very timely,” Climate Commissioner Wopke Hoekstra told reporters in Brussels.

    The proposals include allowing businesses to use international carbon credits to offset their emissions. Under the plan, international carbon credits could be used — starting in 2036 and limited to 3% of benchmark 1990 EU emissions — to reach the 2040 emission reduction target.

    The proposals have to be approved by the EU’s 27 member states.

    More than two-thirds of the severest heat waves in Europe registered since 1950 have occurred since 2000, the World Meteorological Organization says.

    After Spain already set a record for June air temperatures, Spanish port authorities recorded the hottest ever water temperature readings for June in both the Mediterranean and the part of the Atlantic nearest to France.

    Experts say higher surface temperatures are bad for sea life and make for warmer nights on shore.

    “A much warmer sea around us contributes to the nights not cooling down, which is detrimental to people’s rest,” Manuel Vargas, researcher at the Oceanographic Center of Malaga, told The Associated Press.

    Also in Spain’s southern city of Malaga, the international Red Cross set up an air-conditioned “climate refuge” to help residents. The Spanish Red Cross was itself providing an “assisted bathing service” to help people with reduced mobility to cool down in waters at the beach.

    Heat alerts were issued for 17 Italian cities Wednesday. The corresponding surge in air conditioning was straining the electric grid and causing periodic blackouts. On Tuesday, parts of Florence’s historic center had a blackout following a surge in electricity use, energy company Enel said.

    Italy’s labor ministry, meanwhile, summoned union representatives to a meeting Wednesday to finalize a protocol on protecting farm, construction and other workers who labor outdoors from heat exposure. This came after a construction worker died in Bologna this week.

    On Tuesday, Catholic bishops from Asia, Africa and Latin America met in the Vatican to demand climate justice for the parts of the world most affected by rising temperatures.

    France’s national weather agency kept four departments under red alert on Wednesday after temperatures exceeded 40 C (104 F) in many towns.

    The summit of Paris’ iconic Eiffel Tower remained closed until Thursday for “everyone’s comfort and safety.”

    In Switzerland, one of the two reactors at the Beznau nuclear power plant was shut down as part of efforts to prevent excessive warming of the Aare River, so as not to further burden wildlife and the overall ecosystem in already hot weather, operator Axpo said.

    Hundreds of people in the central town of Soest cooled down on a baking-hot Tuesday night by taking on the local fire brigade in a water fight. Townsfolk were armed with water guns, the first responders with fire hoses.

    ‘Squid Game’ director reveals original ending of final season before reviving player 222

    Squid Game director Hwang Dong Hyuk recently revealed that the globally streamed Netflix drama originally had a different finale.

    In an interview with Joongang Ilbo, he said the first version of the script ended on a more hopeful note, with protagonist Seong Gi Hun meeting Hwang Jun Ho and travelling to the US to see his daughter.

    Hwang said he changed course after reflecting on present-day global crises. “I personally started to feel that surviving in this world was becoming increasingly difficult. Inequality is deepening, the threat of war is growing, and yet no one is taking responsibility,” he explained.

    The director added that stories of extreme wealth, including Jeff Bezos’s reported $51.7 million wedding, helped solidify his decision to rework the ending.

    “I felt that now is the time for older generations to let go a bit of their growth, development, and desires,” Hwang said, noting that this inspired him to include a child in the final storyline to symbolise future generations.

    The newly shared version of events has reignited discussion about the show’s conclusion and the societal critique embedded within. Hwang’s comments offer deeper insight into the intentions behind the darker direction, even if it diverged from what many expected.

  • The Right Way to Step Down as CEO

    The Right Way to Step Down as CEO

    HANNAH BATES: Welcome to HBR On Leadership, case studies and conversations with the world’s top business and management experts—hand-selected to help you unlock the best in those around you.

    When a CEO steps down, it can trigger a domino effect of chaos. Boards—often caught off guard—have to jumpstart the search for a successor. And in the process, they sometimes exclude the departing CEO from the search or transition—leading to a loss of institutional knowledge and broken trust. But it doesn’t have to be this way.

    Leadership advisors Rebecca Slan Jerusalim and Navio Kwok say the relationship between a board and CEO can make or break the changing of the guard. They spoke to Curt Nickisch on HBR IdeaCast in 2024 about best practices for CEO transitions.

    CURT NICKISCH: Rebecca and Navio, welcome.

    REBECCA SLAN JERUSALIM: Thank you. We’re thrilled to be here.

    NAVIO KWOK: Thank you. Thanks for having us.

    CURT NICKISCH: Obviously, the CEO transition is super important to a company. Is that importance something that means that people really give it a lot of attention and do it right, or that there’s so much pressure to do it right that people kind of fumble it as they try to manage it well?

    REBECCA SLAN JERUSALIM: Well, I would say there’s tons of work out there looking at the succession process, what parts of the succession process are really critical, and particularly even around CEO succession. What is the right step and cadence to this? What is the board’s involvement? What role does the incoming CEO play?

    And what hasn’t been studied or looked at or really understood is the experience of that person who’s so pivotal to the organization; the person who has been at the helm of the organization, setting the strategy, managing the strategy, creating the organizational culture. How does that person’s experience in transitioning out of the role really impact the organization, the succession experience, as we are really very much focused on the incoming CEO?

    NAVIO KWOK: I think we often also see that there’s a bit of this tension between how urgent something is and how important it needs to be. And so CEO succession for a board and possibly the top team as well is something that is extremely important, but not very urgent, because these decisions tend to happen well in advance unless there was an emergency situation. And so what a board will do is they’re going to focus on the day-to-day, and naturally, non-urgent important things are always going to get pushed off, and I would bucket succession in that category, and as a result, it’s not always top of mind.

    CURT NICKISCH: And then it becomes top of mind very quickly often. In your research, you found that 83% of CEO successions were initiated by the CEO themselves, which kind of surprised me a little bit. You kind of feel like these people are supposed to be in the hot seat and if they’re not performing, they’re out and we need to get somebody else in. And really, it’s kind of mostly largely on their timelines.

    NAVIO KWOK: Yeah. I had seen some research. I think they plotted the performance trajectories of CEOs, those that were performing well and those that weren’t, and then they kind of looked at whether or not they initiated succession or if they were forced out, and actually, that isn’t a strong predictor. So in recent years, the performance of the CEO doesn’t always have that direct contribution to when they step down. And so I think that plays into why mostly, we found in our sample, it’s CEO initiated and it aligns to what you can gather from public CEO data on at least why CEOs or why boards reference CEOs stepping down is it’s a retirement decision.

    REBECCA SLAN JERUSALIM: I would say we were also quite surprised at the number of CEOs who self-initiated the succession. I mean, if you go through any kind of board governance training, you really know that succession is supposed to be really top of mind and not a last minute decision in and around who will be the next successor, but this should be a real process around identifying early, building up the capabilities of internal successors and running through different scenarios to be able to put the right person in the role. And very much a good portion of our sample, and you referenced 83%, many of them self-initiated, and what we found was also fascinating was that they really surprised the board.

    CURT NICKISCH: Yeah. You had a story in the article of a board that met eight times to try to convince the CEO to stay when they needed to be spending that time on not trying to arm twist an unwilling executive to be unhappy longer, but go out and find the replacement.

    REBECCA SLAN JERUSALIM: And some of the reasons that CEOs were initiating the succession were reasons that the board could have and should have had better insight into long before the CEO made that declaration, so things like we talk about temporal reasons, age and tenure in role. Those are easy things that a board can have regular ongoing conversations with the CEO about.

    A couple of the other reasons CEOs announced their readiness for succession were really around, they saw that there were future needs of the organization that they couldn’t necessarily or shouldn’t necessarily be the ones delivering on. And they also recognized that they could potentially be a blocker to succession and that there were people ready or really should be in the process of being ready for that CEO role, and they didn’t want to block their opportunity.

    And so these are two things that really stood out to us because a lot of what has been written about CEO succession speaks to the ego that’s involved in being at the top of the house and not wanting to relinquish that seat for others. And in actual fact, there were some really important and different ideas that came through these conversations that boards should really be talking to the CEOs about and not worried to the same extent that it is purely ego-driven or a hold on power that is keeping these CEOs in place.

    CURT NICKISCH: Yeah, no, I suppose stories of people being CEOs, being forced out, burning it all as they go, right, those are big things that scare boards and scare a lot of people, but it’s probably few and far between when it’s really somebody who just says, “It’s time. I’m getting tired,” right?

    REBECCA SLAN JERUSALIM: They probably make the news more.

    CURT NICKISCH: You’ve outlined the ways that they should be more proactive before this news comes. Once the news comes, what mistakes do you see boards make at that point?

    NAVIO KWOK: One that comes out through that research is the level of CEOs’ involvement in their own succession process. So in our research, we identified five things that they did all the way from just canvassing for candidates all the way to onboarding. And so if we leave aside onboarding, which most CEOs did have some degree of involvement there, we found nearly one in four CEOs were excluded from that process entirely. You know, leave it to us.

    We didn’t use this language in our paper, but it reminds me of the RACI framework when it comes to project management. You’ve got responsible, accountable, consulted and informed, and the board is accountable for succession because the board will be there when the old CEO steps down and new one comes in, but who’s responsible? I think we would say that it should be the outgoing CEO to some extent – more than one in four being excluded entirely. And there’s all these reasons we found why it’s very important actually for the organization.

    CURT NICKISCH: Well, it just stands to reason for any job, right? We’ve all left jobs and known that ideally when you leave a job, it’s a place that’s better than it was before you arrived. And it’s not just the hours of your time doing something that can be replaced, that it’s actually a stronger organization after you leave, but I don’t know, if you overlap with the person who’s replacing you to help train them, that that’s a very positive thing for an organization and it’s almost the same idea for CEOs, it’s just that it’s a lot trickier when you can only have one person in charge, but you go from one person to the next, so how do you handle that transition? So what do you tell CEOs that are in this position? What’s your advice for them?

    REBECCA SLAN JERUSALIM: Listen, ultimately, when done right, there is a role for them to play in the succession process, but that they do also have to recognize that they aren’t going to have full control. The control here will ebb and flow throughout the process. And for them, what the connection is that the control piece, we likened it to or we connected it to mattering, that they are so used to having such a tremendous impact on every decision that the organization makes, that not having the ability to have some control or impact here actually connects to their ability to feel like they matter, like they have value, like they have input. And when they’re not given that kind of opportunity to weigh in, there’s a deeper kind of psychological need in and around wanting to show that they still have some value here to add.

    CURT NICKISCH: It’s kind of an interesting dance, right? Should they offer information? Should they wait until they’re asked? What is the protocol there?

    REBECCA SLAN JERUSALIM: Much of that has to do with how they operate with the board in any other matter. One of the strongest findings that we found is the connection and the strength of relationships between the CEOs and boards were predictive, and I say predictive, predictive, air quotes, this was a qualitative study, not a causative exploration, but the strength of the relationship between the boards and the CEOs really impacted how the overall experience of the CEOs in the succession process.

    NAVIO KWOK: It’s like when you want to ask for a favor from someone in your network, it’s much more helpful and productive if you’ve had an existing relationship with them and then the request comes. But sometimes we have friends in our network where they only come to us when they need something. And that to me, what might be akin to a CEO board relationship, which is there’s quite a bit of a chasm between it, and so they’re only communicating when there are things that need to be discussed, and now you’ve got this big thing that we have to work with in theory together. It’s not the first time they’re meeting, but the relationship is so new and you’re trying to build this relationship at that very tricky point in time where there is so much risk even on a good day and a well-thought-out succession process.

    CURT NICKISCH: Well, it makes it sound like then it’s also incumbent on the outgoing CEO to be communicating with the board earlier so that it isn’t a surprise and that emotions don’t flare up when they do give that announcement.

    REBECCA SLAN JERUSALIM: That’s right. It should be a long ongoing conversation. And CEO succession should not be considered kind of a momentary or moment in time. It should be a years in the making, ongoing conversation between the CEO and the board and real identification and preparation of key successors along the way; should make the board feel confident that they’ve got optionality, that the CEO is on top of this and helping and developing these folks; that the board has visibility to them.

    And so when the CEO then announces their willingness and readiness for succession, the board should really feel like they’ve got a line of sight to who those high potentials and those potential candidates are, that they’ve been built up over the years, that they have clarity around what that profile looks like. And yes, there might be tweaks along the way, but it shouldn’t come as such a shock and surprise that this is happening.

    NAVIO KWOK: I think the implication too for any manager of a team or a leader in an organization is to always have a strong bench. We’re not expecting boards to be not surprised when a CEO says they want to step down. We’re not asking boards to not try and persuade and shift the timeline a little bit, but they should be prepared for that very inevitable outcome. And so for any leader or manager, you should have a deep bench. An example is the Vancouver Canucks were just in a playoff run.

    CURT NICKISCH: This is an NHL hockey team…

    NAVIO KWOK: Yes, NHL hockey team and the goalie was the back-up to the back-up. That was the one who ended up playing because the first goalie was injured and then something happened with the second goalie. So we’re thinking that all sports teams, sports team managers, they have an awareness of where they’re going to pull talent. Now, whether or not it comes to fruition like this case, it’s not always going to be a success story, but at least having an awareness of the key players that you can pull on when needed is very important and when it comes to CEOs, especially so because there is so much that is on their shoulders when they step into that role.

    CURT NICKISCH: What did your research find for the best practices for outgoing CEOs?

    NAVIO KWOK: I’ll share a story. One CEO said to more clearly demarcate their roles and responsibilities and the time at which one person was officially going to be enrolled. So this particular CEO had said they felt they were quite clear that, “I’m still CEO until a certain date, then you’re going to step in,” but it seemed to blur, and in fact, he could see the board members and certain top team members shift their allegiance to the new individual, and so there’s a bit of almost encroaching of responsibilities. So being more clearly demarcating, whose responsibility is going to stop and start when that was fairly notable, and I would say, Rebecca, it’s probably part of the transition phase of succession.

    REBECCA SLAN JERUSALIM: Yeah, I would say two related things. One is many of them talked about taking their successor with them to any meetings, external meetings, vendors, suppliers, board meetings, et cetera, so that they could really get the benefit of the outgoing CEOs’ relationships and the tie to whatever relationship they were fostering.

    This clarity and demarcating roles and responsibilities is true for the board with the CEO and really laying out what that transition plan should be and look like, what the timeline is, what the responsibilities are. And some of them even talked about, and few, but some of them did talk about the board having a role in that being their end of the day performance review of how much have you helped support your successor in transitioning.

    CURT NICKISCH: Now, no matter how clear the role is, it’s still hard, right? You may have a very clearly demarcated when the other person takes over, but then they take over and their priorities are different. The things that you’ve really thought are important as CEO all of a sudden are maybe lower down on the priority list. Even though you want to leave the role, to see somebody else do things differently, there’s got to be tough emotions there.

    REBECCA SLAN JERUSALIM: There is a tremendous amount of emotion throughout the entirety of this process. A real roller coaster, again, buffered by the strong trusting relationship with the board. But I’ll give you a sense of what that roller coaster looked like. The emotions, the outgoing CEOs were very much managing their own emotions as well as the board’s emotions, the senior team’s emotions as well.

    Prior to announcing that the succession process, it can be quite lonely for CEOs, for outgoing CEOs, knowing that they will at some point exiting that role. Lonely, I say, because they’re not necessarily able to share the news that they will be finding a successor initially, and there’s not that many people or places that they can turn to share some of that emotion. It can feel dishonest in some way.

    But post-announcement, there can be excitement about handing over to the next successor. We heard stories of grief and distress in giving up the job. There can be a frustration with lack of involvement. And Navio shared some stories about the senior team kind of turning away from the outgoing CEO, even if they were still in the seat.

    CURT NICKISCH: Sort of a lame duck kind of response?

    REBECCA SLAN JERUSALIM: That’s right. They can feel guilty if they’re blamed for this process going poorly. One of the CEOs who we spoke to even talked about the stages of grief having to give up that seat, and this CEO actually didn’t fully exit from the organization, stayed on in an executive chair role, and so was still tied to the organization in some way, and yet still likened the experience of moving out of that role – it was his decision – but moving out of that role and still feeling like this was a tremendous emotional impact.

    And so when asked about, “How do you deal with that? How do you recognize that?”, he said even just naming the experience and being aware or cognizant that this could and very likely that this roller coaster of emotions is present and can impact you – leaning into that a little bit more. We’re kind of taught there’s no emotions in the boardroom, but in actual fact, this is a very real human experience.

    CURT NICKISCH: Personal, yeah.

    REBECCA SLAN JERUSALIM: It’s very personal. And so it’s really critical to have good trusted advisors to talk through that experience, to recognize that it may very easily happen and have some plan around how you’re going to manage that kind of feeling and emotion.

    NAVIO KWOK: Yeah. I want to give my wife Alana credit for this. She’s a clinical psychologist in training. She says, “name it to tame it,” with regards to emotions, so just simply being able to have a label for it is actually quite impactful in understanding what it is. And emotions in general I think especially in business, we talk about how important emotional intelligence is, but we don’t actually create or facilitate an environment where people are comfortable to talk about their emotions, and so it’s a little paradoxical to expect someone to have that skill, but there’s no opportunity to really kind of practice it.

    And then when there’s something as major as a succession when you probably should be fully ready to utilize those skills, well, you never had any opportunity to practice up until that point, and we’re asking the CEO that they actually can’t talk about at all. So it’s this weird dynamic they have to deal with.

    With that CEO that Rebecca had just mentioned too, he raised a good point that you might want to be aware of just what your triggers are, and you might not know what they are until you see them. So for that individual, what really struck them initially was when their office was no longer in the center of their building. So it was when they were more on the periphery physically, that’s when he felt, “Okay, this is real. This is significant and I’m the old guard leaving.”

    So I think that speaks to an earlier question you had about just what a CEO can do, the outgoing CEO and the incoming CEO, is being aware of the symbolic nature of executive leadership at the top. And so this CEO actually made a concerted effort to move his office away from the center, and still he was hurt. That symbolic nature is very important, and it can both help people support the incoming CEO and sometimes unexpectedly can make it very real for the outgoing CEO that it’s very real and it’s time for you to step down.

    CURT NICKISCH: Yeah. You’ve gone from being a very, very important person; it’s a part of your identity, it’s a big identity change.

    REBECCA SLAN JERUSALIM: It’s interesting you call that out. One of the key questions that we asked our participants is, is CEO something you do or did or something you are? And it’s very hard at the top of the house to really be able to separate an identity. These CEO jobs are 24 hours, seven days a week. You’re all in. And when we asked that question, there was kind of a rough split. 47% said that it is something that they did, and 43% said it was something that they were. The rest were kind of a bit of both.

    And that’s telling. I mean, even for the folks who had what we would say very low ego, kind of salt of the earth, very humble folks who would describe their role as CEO at the bottom of the organization, it was still a very personally challenging roller coaster experience to navigate. And many of them felt it was really helpful to have the reflection, the time to reflect on that experience, because very few people actually, as you’re going through it, you’re not taking the time to reflect on it.

    And then you’ve left the role and there’s very little that people want to know and understand of your experience through that, but yet it was helpful to both understand and then for them in their next role, iteration, whether it’s as another CEO or on a board, to actually have really strong sentiment and feeling about how this should go and what feels right beyond the specific governance of it was helpful and impactful for them.

    CURT NICKISCH: What are some of the best lessons here for other executives or really anybody leaving a job and handing it over to somebody else that you think we all can learn from?

    NAVIO KWOK: I’d say relevant even well before you’re leaving a job is to not fully tie your identity to either your job or a role. I think that has particular implications with AI and its potential risk of displacing certain workers and at a minimum, changing the job that they’re doing in ways that we can’t necessarily forecast.

    So Microsoft and LinkedIn came out with a work trends report just very recently, and they found that on LinkedIn’s fastest growing jobs in the U.S., many of them, I think maybe the number was two-thirds, weren’t in existence 20 years ago, so you don’t even actually know what job you might do in the future. And so if you tie your identity and sense of self to what you’re doing right now in the organization you’re in, it’s going to make that process of letting go, stepping down or changing jobs much more difficult.

    So I’m not saying don’t tie it to it, but I’m saying consider it a little bit differently. So what do you tie it to?

    And so I read a story in a book by Dan and Chip Heath, they’re brothers, one of them at least is with Stanford, and they shared a story of Floyd Lee, who was a retired Marine Corps and Army chef. He was 25 years in service, had retired, then the Iraq war happened, so he actually re-enlisted as a chef to help out. And typically, army food is very bland, and the mess hall he was leading was pristine food. Things were beautiful, food tasted great, and people would come from outside of that mess hall on weekends to eat his food. And he said for him, it’s not that he’s in charge of food, he’s in charge of morale.

    And so if you align your identity to that kind of message for you and your role, I’m in charge of morale, then if for whatever reason you can’t be a chef anymore, there are still other ways in which you can satisfy that personal value and need of being in charge of morale. But if you’re tied exclusively to being a chef, an army chef for that individual in particular, then it makes stepping down very hard if that job no longer exists in the future.

    REBECCA SLAN JERUSALIM: I would just add, and we asked this of some of the CEOs, what kind of advice would you have for folks? Part of it is like Navio mentioned, finding your intrinsic purpose. What is the value that you want to add? Where do you get the most joy? Many of the CEOs in our sample did not step down and retire. They went on to do other things.

    There was also this question of avoiding just creating some busy work because you’re kind of worried you’ve got such a full work life and many can step on wanting to keep that pace up, not recognizing that without true planning and recognizing what next – they’re very strategic in their work life, but not very strategic in planning their personal life outside of this key role. And so thinking about that, having regular conversations, planning for it before the last day is really important.

    We also heard about spouse and family renegotiations. What? You’re around now more? What does this look like? Or we said we would travel and now you’ve kind of thrown yourself into all this other-

    CURT NICKISCH: I don’t know you! Yeah.

    REBECCA SLAN JERUSALIM: Yeah. Board work, busy work. So there’s some renegotiation that needs to happen as well, but it does go hand in hand with really purposely thinking about and planning for that next stage.

    CURT NICKISCH: Rebecca and Navio, thanks so much for coming on the show to share your research and to talk about this really important transition.

    NAVIO KWOK: Thank you. It was a pleasure.
