Switch 2 turned up on our doorstep this afternoon and here's what you can look forward to if you plug yours in at just past midnight tonight - including one warningTech21:32, 04 Jun 2025Updated 21:32, 04 Jun 2025Here's what Nintendo sent usAfter months of writing about the Nintendo Switch 2 daily (and getting very excited for Mario Kart World), it was a bit of a strange feeling to have the console dropped off at my doorstep earlier today.While I had preordered, Nintendo sent out the console and some peripherals, so I'm in a position to tell you what you can expect if you're attending a midnight launch, or if you're currently queuing outside your store.‌Looking for a more detailed preview of the hardware? You can find that here, and we've also got hands-on impressions of Mario Kart World and Nintendo Switch Welcome Tour.‌Mario Kart World is Nintendo's big Switch 2 launch title(Image: Nintendo)When powering on your Switch 2, you'll need to connect to the internet to download the all-important firmware update that turns it from a pricey paperweight into a nifty console.The console will also introduce you to some of its features and prompt you to add a MicroSD Express card (doing so will format it so it's ready for use).Article continues belowYou can complete the setup with any version of the Switch 2 controllers, and you'll be prompted to start a system transfer from your original console if you have one.We'd recommend doing so, because it'll transfer your saved data to your new system, but it does come with an inconvenience tied to our biggest Switch 2 bugbear so far: painfully slow download speeds.Logging into the console and updating the firmware took about 20 minutes, but downloads move glacially slow.‌Add to that the console trying to download everything from your Switch 1 at once, and I had to spend a few minutes closing downloads down.Even the more modestly-sized games like Puyo Puyo Tetris were dragging on my gigabit Wi-Fi, although I'd imagine it's down to the 'pipes being clogged' as far as servers go.Still, if you're planning to play anything tonight, you might want to stick to physical media for a bit.Article continues belowWhile the Joy-Con are great, I'm massively impressed by the Pro Controller. We'll have a full live blog running most of the day tomorrow to talk more about Switch 2 on its official launch day, but I'll be leaning towards the more traditional pad for my Zelda playthroughs and more.For now, though, I'm pretty pleased I have a physical copy of Mario Kart World to keep me going until Sony's State of Play tonight.

As the Nintendo Switch 2 launches, these are our hopes and dreams for the console Image credit: Nintendo Feature by GamesIndustry.biz Staff Contributor Published on June 5, 2025 With the Nintendo Switch 2 launching today, it closes out a rocky pre-launch period of tariffs, fiery price discussions around software and hardware, and some retailers cancelling pre-orders. Much of that will feel like a distant memory once the hotly-anticipated console is in players' hands, and they're trying out the first new Mario Kart game in more than 11 years. There's always something special about Nintendo hardware. Even with the Wii U, the console manufacturer's biggest dud in recent memory, that was still the case. While the Switch 2 is firmly an evolution of 2017's Switch and not anything bolder in terms of input or form factor, Nintendo's unbelievable run of great software over the past eight years looks set to continue. The downside for consumers, of course, is that they will be paying much more for some of those titles than they did on the last console. Below, to celebrate its launch day, the GamesIndustry.biz team shares its realistic hopes and dreams for the years to come on Switch 2. A fresh take on exclusive IP Nintendo has already demonstrated that it's willing to switch it up in terms of new takes on its iconic franchises, with the destructible levels of Donkey Kong Bananza and the open roads of Mario Kart World. But I have an appetite to see the same approach taken with continuations of beloved franchises like The Legend of Zelda, 3D Mario, and Pokémon. While Breath of the Wild and Tears of the Kingdom are getting enhanced versions and the newest Pokémon Legends title launches this fall, Nintendo has the opportunity to revitalise some of its beloved IP with boosted hardware and fan interest. Not only that, but it could flip the script entirely and debut a brand new franchise unrelated to anything that’s come before it – something that would become intertwined with the Switch 2 and inspire a new generation of players and developers. – Sophie McEvoy The end of bad Switch ports While games like Doom and The Witcher 3 demonstrated that miracles were possible with the Nintendo Switch's limited hardware capabilities, numerous ports from more powerful platforms fell short. From the notoriously rough visual downgrade of Batman: Arkham Knight to the choppy port of WWE 2K 2018, sometimes visually intensive games have made their way to the console with a whiff of 'buyer beware' about them. In some cases, like the Kingdom Hearts games, 'cloud' versions bypassed trying to run natively on the hardware altogether, which was a compromise too far for many players. That's a trend the Switch 2, with its out-of-the-gates impressive ports of Cyberpunk 2077 and Civ 7, could really do without. Inevitably, we will reach a point with the next Xbox and PlayStation consoles where the disparity with the Switch 2 becomes too great, and we could potentially see a similar downslide in ports. But hopefully the quality level reached with this first wave of releases sets a high standard for what's to come. Users' tolerance for lower quality multiplatform releases has been tested too much during the latter years of the Switch's lifecycle. – Samuel Roberts Switch 2 is at the heart of indie games Image credit: ConcernedApe The early years of the Switch were a honeymoon period for indie games, causing a gold rush of publishers and developers getting their back catalogues on the platform. As the eShop became swamped with shovelware, while Nintendo did little to improve discoverability (until very recently), Steam quickly became the de facto home for indie games again. There's still nothing like playing an indie game on Switch. The portability remains a cut above other devices with a similar form factor, like the Steam Deck. While Nintendo shows it values smaller games with its Indie World showcases, there's still a disconnect between the intent of those presentations and how easily indie games are actually discovered on Switch. Using the eShop to celebrate good taste in games should be a goal of Nintendo's during this generation. A golden age of indies comparable to the original Switch launch seems unlikely – the moment has probably passed on that. But more consistent curation would have a massive amount of value. – Samuel Roberts Nintendo shows that the mouse has the magic The unveiling of the Switch showed that Nintendo learned a lot of lessons from the Wii U, itself a failed follow-up to the Wii: the company didn't rock the boat. It's the same form factor you know from the original Switch, with a clear '2' in the name. All its more novel secondary features – like the Joy-Con's mouse controls – are not at the centre of the marketing messaging like the Wii Remote or DS touchscreen were for those consoles. This was wise in a few practical ways. It means there are no interface-based headaches in porting a game onto the console, paving the way for (theoretically) good third-party support. Consumers, developers, and publishers know what they're getting. Still, it means the console is going to feel largely familiar as an experience. The hope, then, is that deeper into the generation, Nintendo and other developers find new and interesting things to do with the mouse. Competitive wheelchair basketball game Drag x Drive is Nintendo's first attempt at this, but the drab art style doesn't inspire much confidence. Previous breakthrough exclusives like Arms and Splatoon felt like a much bigger deal. – Samuel Roberts More than just a console As a handheld device, the Switch ended up being more than just a games console. Subscription-based services like Crunchyroll and InkyPen provide access to anime, comics, and manga, while the YouTube app lets players watch a (albeit limited) selection of movies and shows. With the improvements in screen resolution, the Switch 2 would benefit from integrating more streaming services like Netflix, Disney+, and Amazon Prime. Sure, you can use these apps on phones and laptops, but it would be convenient to have everything on one device – particularly a handheld console that's a popular traveling companion. And with social connectivity being a major selling point of the new console with GameChat, there's an opportunity to host streaming parties of shows and films on top of playing games. – Sophie McEvoy The GameCube library isn't left to fester on Nintendo Switch Online On day one, Nintendo Switch Online's Expansion Pack brings GameCube games to Switch 2 players: The Legend of Zelda: Wind Waker, F-Zero GX, and Soulcalibur 2. More will be coming, but if Nintendo's previous form with its classic console libraries are anything to go by, it will be a glacial wait. I hope I'm proven wrong. Possibly complicating matters is that some key GameCube titles have already been ported to Switch, like Paper Mario: The Thousand-Year Door, Pikmin 1 and 2, and Metroid Prime. The console's best game, Resident Evil 4, has been widely available for years on other platforms. The best case scenario here, then, is that Nintendo brings some more unusual or unexpected games to the service – the coming inclusion of Chibi-Robo, a cult GameCube game that's been hard to get hold for many years, is a strong indicator that the company is thinking outside the more obvious Mario and Zelda games. Rogue Squadron 2: Rogue Leader, Eternal Darkness: Sanity's Requiem, and Metal Gear Solid: The Twin Snakes would be on my personal wishlist. And maybe Starfox Adventures, too, just to hear everyone complain about it again. – Samuel Roberts A new take on Zelda in time for the movie This one is pretty much guaranteed. After reinventing the Zelda series with the open world games Breath of the Wild and Tears of the Kingdom, both of which celebrated player freedom and ingenuity, it will be fascinating to see what tack the team behind these games take next. "I think [TOTK] is – to use a bit of a term – an apotheosis, or the final form of that version of The Legend of Zelda," said producer Eiji Aonuma in a 2023 interview with Game Informer. "In that regard, I don't think that we'll be making a direct sequel to a world such as that that we've created." My prediction: in the same way Super Mario Wonder gave players a fresh spin on a classic Mario 2D platformer experience following 2023's (terrible, if you ask me) Super Mario Bros. movie, I could see a similar tack taken with 2027's live-action Zelda movie. A game that seems superficially familiar, but is bursting with new ideas, would bridge the gap between veteran Nintendo players and newbies. – Samuel Roberts

Snowflake's growth among large enterprise customers faces a significant bottleneck tied to the sluggish replacement cycles of existing on-premises data warehouse systems, according to finance vice president Jimmy Sexton. Speaking at a Jefferies conference, Sexton explained that while the cloud data company secured two deals worth more than $100 million each in the financial services sector during its latest quarter, such migrations unfold over multiple years as "cumbersome projects."

May 30, 20253 min readWhat Causes Glaciers to Collapse like the Event That Buried a Swiss Village?Climate change and thawing permafrost play a role in destabilizing glaciersBy Jen Schwartz edited by Dean VisserThe small village of Blatten in the Swiss Alps was largely destroyed by a landslide that occurred as a result of the partial collapse of the Birch Glacier on May 28, 2025. Alexandre Agrusti/AFP via Getty ImagesAn unstable glacier in the Swiss Alps collapsed this week, sending a deluge of rock, ice and mud through the valley below and burying the village of Blatten almost entirely. Scientists had warned about the possibility of a dangerous event related to the glacier, and village residents had been evacuated days earlier—but the glacier’s near-total breakup came as a surprise. One person is reported missing. Government officials initially estimated the debris deposit to be several dozen meters thick and approximately two kilometers long. Making matters worse, the collapse of the glacier, called the Birch Glacier, blocked the flow of the Lonza River, which runs through the valley. As a result, a newly created lake upstream from the debris field flooded an area that has now overflowed into the deposit zone, which could cause a debris flow downstream. As of Friday afternoon local time, officials have reported that the water flow is approaching the top of the scree cone, which is the accumulation of loose, rocky debris.Why did the glacier break apart?The glacier’s collapse and the subsequent landslide—which was so intense that it corresponded to a magnitude 3.1 earthquake captured by the Swiss Seismological Service—likely arose from a series of rockfalls that occurred above the glacier over the past couple of weeks. The rocks, dislodged because of high-altitude snowmelt, exerted significant pressure on the relatively small glacier, according to officials. Experts are looking into longer-term factors that may have weakened the glacier’s stability even before those rockfalls. Christophe Lambiel, a glaciologist who also specializes in high-mountain geology at the University of Lausanne in Switzerland, said on RTS Swiss Television that the rockfalls were linked to climate change. “The increase in the falling rocks is due to the melting permafrost, which increases instability,” Lambiel said, as reported on NPR.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.How would climate change lead to a glacier’s collapse?New research published on Thursday in Science finds that, under current climate policies, more than three quarters of the world’s glacial mass could disappear by the end of this century. In this scenario, almost all small and relatively low-elevation glaciers, like the one in Switzerland, would be wiped out. In a 2024 article for Scientific American, journalist Alec Luhn explained that “the deterioration of ice and snow is triggering feedback loops that will heat the world even further. Permafrost, the frozen ground that holds twice as much carbon as is currently found in the atmosphere, is thawing and releasing these stores.” Thawing permafrost is not just dangerous because it creates instability, as in the case of Birch Glacier. As Luhn wrote, “Research has revealed that the permafrost zone is now releasing more carbon than it absorbs, heating the planet further.”Who is at risk from disintegrating glaciers?It’s clear that the weakening of Switzerland’s Birch Glacier was at least partially caused by rockfall. There are other ways in which changes to glaciers are causing risk—and occasional devastation—to people, communities and infrastructure. As a 2023 E&E News article explained, “At least 15 million people worldwide live in the flood paths of dangerous glacial lakes that can abruptly burst their banks and rush down mountainsides.” These so-called glacial lake outburst floods can be fatal and cause catastrophic damage. “The deterioration of the planet’s snow and ice regions,” wrote Luhn in his 2024 article, “is costing the world billions of dollars in damages,” according to a 2024 State of the Cryosphere report What can be done to preserve glaciers—and protect communities?Giant plastic blankets, gravity snow guns and painted rocks are all potential strategies to slow ice melt in the world’s mountain regions. The sound that glaciers make when water is coursing through their icy cracks can be used to predict glacial lake outburst floods—and thus to save lives. There’s also a growing sense of reckoning with the fate of the world’s glaciers. An essay about the Global Glacier Casualty List, which documents glaciers that have melted or are critically endangered, was also released on Thursday in Science. In it, Rice University anthropologists Cymene Howe and Dominic Boyer write, “The world’s first funeral for a glacier was held in Iceland in 2019 for a little glacier called ‘Ok….’ Since then, memorials for disappeared glaciers have increased across the world, illustrating the integral connection between loss in the natural world and human rituals of remembrance.”

The US is less than 250 years old, but some of its most important archaeological sites are older than the Viking seafarers, the Roman Empire, and the pyramids.Many help tell the story of how the first humans came to North America. It's still a mystery exactly how and when people arrived, though it's widely believed they crossed the Bering Strait at least 15,000 years ago."As we get further back in time, as we get populations that are smaller and smaller, finding these places and interpreting them becomes increasingly difficult," archaeologist Kenneth Feder told Business Insider. He's the author of "Ancient America: Fifty Archaeological Sites to See for Yourself."Some sites, like White Sands and Cooper's Ferry, have skeptics about the accuracy of their age. Still, they contribute to our understanding of some of the earliest Americans.Others are more recent and highlight the different cultures that were spreading around the country, with complex buildings and illuminating pictographs.Many of these places are open to the public, so you can see the US' ancient history for yourself. White Sands National Park, New Mexico Footprints at White Sands. National Park Service Prehistoric camels, mammoths, and giant sloths once roamed what's now New Mexico, when it was greener and damper.As the climate warmed around 11,000 years ago, the water of Lake Otero receded, revealing footprints of humans who lived among these extinct animals. Some even seemed to be following a sloth, offering a rare glimpse into ancient hunters' behavior.Recent research puts some of these fossilized footprints at between 21,000 and 23,000 years old. If the dates are accurate, the prints would predate other archaeological sites in the US, raising intriguing questions about who these people were and how they arrived in the Southwestern state."Where are they coming from?" Feder said. "They're not parachute dropping in New Mexico. They must have come from somewhere else, which means there are even older sites." Archaeologists simply haven't found them yet.While visitors can soak in the sight of the eponymous white sands, the footprints are currently off-limits. Meadowcroft Rockshelter, Pennsylvania The archeological dig at the Meadowcroft National Historic Site in 2013. AP Photo/Keith Srakocic In the 1970s, archaeologist James M. Adovasio sparked a controversy when he and his colleagues suggested stone tools and other artifacts found in southwestern Pennsylvania belonged to humans who had lived in the area 16,000 years ago.For decades, scientists had been finding evidence of human habitation that all seemed to be around 12,000 to 13,000 years old, belonging to the Clovis culture. They were long believed to have been the first to cross the Bering land bridge. Humans who arrived in North America before this group are often referred to as pre-Clovis.At the time, skeptics said that the radiocarbon dating evidence was flawed, AP News reported in 2016. In the years since, more sites that appear older than 13,000 years have been found across the US.Feder said Adovasio meticulously excavated the site, but there's still no clear consensus about the age of the oldest artifacts. Still, he said, "that site is absolutely a major, important, significant site." It helped archaeologists realize humans started arriving on the continent before the Clovis people.The dig itself is on display at the Heinz History Center, allowing visitors to see an excavation in person. Cooper's Ferry, Idaho Excavators at Cooper's Ferry in 2013. Loren Davis/Oregon State University One site that's added intriguing evidence to the pre-Clovis theory is located in western Idaho. Humans living there left stone tools and charred bones in a hearth between 14,000 and 16,000 years ago, according to radiocarbon dating. Other researchers put the dates closer to 11,500 years ago.These stemmed tools are different from the Clovis fluted projectiles, researchers wrote in a 2019 Science Advances paper.Some scientists think humans may have been traveling along the West Coast at this time, when huge ice sheets covered Alaska and Canada. "People using boats, using canoes could hop along that coast and end up in North America long before those glacial ice bodies decoupled," Feder said.Cooper's Ferry is located on traditional Nez Perce land, which the Bureau of Land Management holds in public ownership. Page-Ladson, Florida Divers search in the sediment at the Page-Ladson site. Texas A&M University via Getty Images In the early 1980s, former Navy SEAL Buddy Page alerted paleontologists and archaeologists to a sinkhole nicknamed "Booger Hole" in the Aucilla River. There, the researchers found mammoth and mastodon bones and stone tools.They also discovered a mastodon tusk with what appeared to be cut marks believed to be made by a tool. Other scientists have returned to the site more recently, bringing up more bones and tools. They used radiocarbon dating, which established the site as pre-Clovis."The stone tools and faunal remains at the site show that at 14,550 years ago, people knew how to find game, fresh water and material for making tools," Michael Waters, one of the researchers, said in a statement in 2016. "These people were well-adapted to this environment."Since the site is both underwater and on private property, it's not open to visitors. Paisley Caves, Oregon One of the Paisley Caves near Paisley, Oregon. AP Photo/Jeff Barnard Scientists study coprolites, or fossilized poop, to learn about the diets of long-dead animals. Mineralized waste can also reveal much more. In 2020, archaeologist Dennis Jenkins published a paper on coprolites from an Oregon cave that were over 14,000 years old.Radiocarbon dating gave the trace fossils' age, and genetic tests suggested they belonged to humans. Further analysis of coprolites added additional evidence that a group had been on the West Coast 1,000 years before the Clovis people arrived.Located in southcentral Oregon, the caves appear to be a piece of the puzzle indicating how humans spread throughout the continent thousands of years ago.The federal Bureau of Land Management owns the land where the caves are found, and they are listed on the National Register of Historic Places. Swan Point, Alaska Excavators working at the Swan Point site in June 2016. Charles Holmes/University of Alaska, Fairbanks Whenever people arrived in the Americas, they crossed from Siberia into Beringia, an area of land and sea between Russia and Canada and Alaska. Now it's covered in water, but there was once a land bridge connecting them.The site in Alaska with the oldest evidence of human habitation is Swan Point, in the state's eastern-central region. In addition to tools and hearths dating back 14,000 years, mammoth bones have been found there.Researchers think this area was a kind of seasonal hunting camp. As mammoths returned during certain times of the years, humans would track them and kill them, providing plentiful food for the hunter-gatherers.While Alaska may have a wealth of archaeological evidence of early Americans, it's also a difficult place to excavate. "Your digging season is very narrow, and it's expensive," Feder said. Some require a helicopter to reach, for example. Blackwater Draw, New Mexico A palaeontologist excavating a mammoth in Portales, New Mexico, circa 1960. Dick Kent/FPG/Archive Photos/Getty Images In 1929, 19-year-old James Ridgley Whiteman found mammoth bones along with fluted projectile points near Clovis, New Mexico. The Clovis people who made these tools were named for this site.Researchers studying the site began to realize the artifacts found at the site belonged to different cultures. Clovis points are typically larger than Folsom flutes, which were first found at another archaeological site in New Mexico.For decades after Whiteman's discovery, experts thought the Clovis people were the first to cross the Bering land bridge from Asia around 13,000 years ago. Estimates for humans' arrival is now thought to be at least 15,000 years ago.Eastern New Mexico University's Blackwater Draw Museum grants access to the archaeological site between April and October. Upper Sun River, Alaska Excavations at the Upward Sun River, Alaska. Ben Potter/University of Alaska, Fairbanks One reason the dates of human occupation in North America is so contentious is that very few ancient remains have been found. Among the oldest is a child from Upward Sun River, or Xaasaa Na', in Central Alaska.Archaeologists found the bones of the child in 2013. Local indigenous groups refer to her as Xach'itee'aanenh t'eede gay, or Sunrise Girl-Child. Genetic testing revealed the 11,300-year-old infant belonged to a previously unknown Native American population, the Ancient Beringians.Based on the child's genetic information, researchers learned that she was related to modern Native Americans but not directly. Their common ancestors started becoming genetically isolated 25,000 years ago before dividing into two groups after a few thousand years: the Ancient Berignians and the ancestors of modern Native Americans.According to this research, it's possible humans reached Alaska roughly 20,000 years ago. Poverty Point National Monument, Louisiana Poverty Point in Louisiana. National Park Service Stretching over 80 feet long and 5 feet tall, the rows of curved mounds of Poverty Point are a marvel when viewed from above. Over 3,000 years ago, hunter-gatherers constructed them out of tons of soil. Scientists aren't sure exactly why people built them, whether they were ceremonial or a display of status.The artifacts various groups left behind indicate the site was used off and on for hundreds of years and was a meeting point for trading. People brought tools and rocks from as far as 800 miles away. Remains of deer, fish, frogs, alligators, nuts, grapes, and other food have given archaeologists insights into their diets and daily lives.You can see the World Heritage Site for yourself year-round. Horseshoe Canyon, Utah The Great Gallery in Horseshoe Canyon. Neal Herbert/National Park Service Though remote, the multicolored walls of Horseshoe Canyon have long attracted visitors. Some of its artifacts date back to between 9,000 and 7,000 BCE, but its pictographs are more recent. Some tests date certain sections to around 2,000 to 900 years ago.The four galleries contain life-sized images of anthropomorphic figures and animals in what's known as the Barrier Canyon style. Much of this art is found in Utah, produced by the Desert Archaic culture.The pictographs may have spiritual and practical significance but also help capture a time when groups were meeting and mixing, according to the Natural History Museum of Utah.It's a difficult trek to get to the pictographs (and the NPS warns it can be dangerously hot in summer) but are amazing to view in person, Feder said. "These are creative geniuses," he said of the artists. Canyon de Chelly, Arizona The Antelope House at Canyon de Chelly National Monument. Michael Denson/National Park Service Situated in the Navajo Nation, Canyon de Chelly has gorgeous desert views and thousands of years of human history. Centuries ago, Ancestral Pueblo and Hopi groups planted crops, created pictographs, and built cliff dwellings.Over 900 years ago, Puebloan people constructed the White House, named for the hue of its clay. Its upper floors sit on a sandstone cliff, with a sheer drop outside the windows.Navajo people, also known as Diné, still live in Canyon de Chelly. Diné journalist Alastair Lee Bitsóí recently wrote about visiting some of the sacred and taboo areas. They include Tsé Yaa Kin, where archaeologists found human remains.In the 1860s, the US government forced 8,000 Navajo to relocate to Fort Sumner in New Mexico. The deadly journey is known as the "Long Walk." Eventually, they were able to return, though their homes and crops were destroyed.A hike to the White House is the only one open to the public without a Navajo guide or NPS ranger. Mesa Verde National Park, Colorado Visitors line up at Mesa Verde National Park. Shutterstock/Don Mammoser In the early 1900s, two women formed the Colorado Cliff Dwelling Association, hoping to preserve the ruins in the state's southwestern region. A few years later, President Theodore Roosevelt signed a bill designating Mesa Verde as the first national park meant to "preserve the works of man."Mesa Verde National Park holds hundreds of dwellings, including the sprawling Cliff Palace. It has over 100 rooms and nearly two dozen kivas, or ceremonial spaces.Using dendrochronology, or tree-ring dating, archaeologists learned when Ancestral Pueblo people built some of these structures and that they migrated out of the area by the 1300s.Feder said it's his favorite archaeological site he's visited. "You don't want to leave because you can't believe it's real," he said.Tourists can view many of these dwellings from the road, but some are also accessible after a bit of a hike. Some require extra tickets and can get crowded, Feder said. Cahokia, Illinois A mound at Cahokia in Illinois. Matt Gush/Shutterstock Cahokia has been called one of North America's first cities. Not far from present-day St. Louis, an estimated 10,000 to 20,000 people lived in dense settlements roughly 1,000 years ago. Important buildings sat atop large mounds, which the Mississippians built by hand, The Guardian reported.At the time, it was thriving with hunters, farmers, and artisans. "It's an agricultural civilization," Feder said. "It's a place where raw materials from a thousand miles away are coming in." Researchers have also found mass graves, potentially from human sacrifices.The inhabitants built circles of posts, which one archaeologist later referred to as "woodhenges," as a kind of calendar. At the solstices, the sun would rise or set aligned with different mounds.After a few hundred years, Cahokia's population declined and disappeared by 1350. Its largest mound remains, and some aspects have been reconstructed.While Cahokia is typically open to the public, parts are currently closed for renovations. Montezuma Castle, Arizona Montezuma Castle, a cliff dwelling, in Arizona. MyLoupe/Universal Images Group via Getty Images Perched on a limestone cliff in Camp Verde, Arizona, this site is an apartment, not a castle, and is unrelated to the Aztec ruler Montezuma.The Sinagua people engineered the five-story, 20-room building around 1100. It curves to follow the natural line of the cliff, which would have been more difficult than simply making a straight building, Feder said."These people were architects," he said. "They had a sense of beauty."The inhabitants were also practical, figuring out irrigation systems and construction techniques, like thick walls and shady spots, to help them survive the hot, dry climate.Feder said the dwelling is fairly accessible, with a short walk along a trail to view it, though visitors can't go inside the building itself.

smelly shield Penguin poop may help preserve Antarctic climate Ammonia aerosols from penguin guano likely play a part in the formation of heat-shielding clouds. Bob Berwyn, Inside Climate News – May 24, 2025 7:07 am | 4 Credit: Getty Credit: Getty Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only   Learn more This article originally appeared on Inside Climate News, a nonprofit, non-partisan news organization that covers climate, energy, and the environment. Sign up for their newsletter here. New research shows that penguin guano in Antarctica is an important source of ammonia aerosol particles that help drive the formation and persistence of low clouds, which cool the climate by reflecting some incoming sunlight back to space. The findings reinforce the growing awareness that Earth’s intricate web of life plays a significant role in shaping the planetary climate. Even at the small levels measured, the ammonia particles from the guano interact with sulfur-based aerosols from ocean algae to start a chemical chain reaction that forms billions of tiny particles that serve as nuclei for water vapor droplets. The low marine clouds that often cover big tracts of the Southern Ocean around Antarctica are a wild card in the climate system because scientists don’t fully understand how they will react to human-caused heating of the atmosphere and oceans. One recent study suggested that the big increase in the annual global temperature during 2023 and 2024 that has continued into this year was caused in part by a reduction of that cloud cover. “I’m constantly surprised at the depth of how one small change affects everything else,” said Matthew Boyer, a coauthor of the new study and an atmospheric scientist at the University of Helsinki’s Institute for Atmospheric and Earth System Research. “This really does show that there is a deep connection between ecosystem processes and the climate. And really, it’s the synergy between what’s coming from the oceans, from the sulfur-producing species, and then the ammonia coming from the penguins.” Climate survivors Aquatic penguins evolved from flying birds about 60 million years ago, shortly after the age of dinosaurs, and have persisted through multiple, slow, natural cycles of ice ages and warmer interglacial eras, surviving climate extremes by migrating to and from pockets of suitable habitat, called climate refugia, said Rose Foster-Dyer, a marine and polar ecologist with the University of Canterbury in New Zealand. A 2018 study that analyzed the remains of an ancient “super colony” of the birds suggests there may have been a “penguin optimum” climate window between about 4,000 and 2,000 years ago, at least for some species in some parts of Antarctica, she said. Various penguin species have adapted to different habitat niches and this will face different impacts caused by human-caused warming, she said. Foster-Dyer has recently done penguin research around the Ross Sea, and said that climate change could open more areas for land-breeding Adélie penguins, which don’t breed on ice like some other species. “There’s evidence that this whole area used to have many more colonies … which could possibly be repopulated in the future,” she said. She is also more optimistic than some scientists about the future for emperor penguins, the largest species of the group, she added. “They breed on fast ice, and there’s a lot of publications coming out about how the populations might be declining and their habitat is hugely threatened,” she said. “But they’ve lived through so many different cycles of the climate, so I think they’re more adaptable than people currently give them credit for.” In total, about 20 million breeding pairs of penguins nest in vast colonies all around the frozen continent. Some of the largest colonies, with up to 1 million breeding pairs, can cover several square miles.There aren’t any solid estimates for the total amount of guano produced by the flightless birds annually, but some studies have found that individual colonies can produce several hundred tons. Several new penguin colonies were discovered recently when their droppings were spotted in detailed satellite images. A few penguin colonies have grown recently while others appear to be shrinking, but in general, their habitat is considered threatened by warming and changing ice conditions, which affects their food supplies. The speed of human-caused warming, for which there is no precedent in paleoclimate records, may exacerbate the threat to penguins, which evolve slowly compared to many other species, Foster-Dyer said. “Everything’s changing at such a fast rate, it’s really hard to say much about anything,” she said. Recent research has shown how other types of marine life are also important to the global climate system. Nutrients from bird droppings help fertilize blooms of oxygen-producing plankton, and huge swarms of fish that live in the middle layers of the ocean cycle carbon vertically through the water, ultimately depositing it in a generally stable sediment layer on the seafloor. Tricky measurements Boyer said the new research started as a follow-up project to other studies of atmospheric chemistry in the same area, near the Argentine Marambio Base on an island along the Antarctic Peninsula. Observations by other teams suggested it could be worth specifically trying to look at ammonia, he said. Boyer and the other scientists set up specialized equipment to measure the concentration of ammonia in the air from January to March 2023. They found that, when the wind blew from the direction of a colony of about 60,000 Adélie penguins about 5 miles away, the ammonia concentration increased to as high as 13.5 parts per billion—more than 1,000 times higher than the background reading. Even after the penguins migrated from the area toward the end of February, the ammonia concentration was still more than 100 times as high as the background level. “We have one instrument that we use in the study to give us the chemistry of gases as they’re actually clustering together,” he said. “In general, ammonia in the atmosphere is not well-measured because it’s really difficult to measure, especially if you want to measure at a very high sensitivity, if you have low concentrations like in Antarctica,” he said. Penguin-scented winds The goal was to determine where the ammonia is coming from, including testing a previous hypothesis that the ocean surface could be the source, he said. But the size of the penguin colonies made them the most likely source. “It’s well known that sea birds give off ammonia. You can smell them. The birds stink,” he said. “But we didn’t know how much there was. So what we did with this study was to quantify ammonia and to quantify its impact on the cloud formation process.” The scientists had to wait until the wind blew from the penguin colony toward the research station. “If we’re lucky, the wind blows from that direction and not from the direction of the power generator,” he said. “And we were lucky enough that we had one specific event where the winds from the penguin colony persisted long enough that we were actually able to track the growth of the particles. You could be there for a year, and it might not happen.” The ammonia from the guano does not form the particles but supercharges the process that does, Boyer said. “It’s really the dimethyl sulfide from phytoplankton that gives off the sulfur,” he said. “The ammonia enhances the formation rate of particles. Without ammonia, sulfuric acid can form new particles, but with ammonia, it’s 1,000 times faster, and sometimes even more, so we’re talking up to four orders of magnitude faster because of the guano.” This is important in Antarctica specifically because there are not many other sources of particles, such as pollution or emissions from trees, he added. “So the strength of the source matters in terms of its climate effect over time,” he said. “And if the source changes, it’s going to change the climate effect.” It will take more research to determine if penguin guano has a net cooling effect on the climate. But in general, he said, if the particles transport out to sea and contribute to cloud formation, they will have a cooling effect. “What’s also interesting,” he said, “is if the clouds are over ice surfaces, it could actually lead to warming because the clouds are less reflective than the ice beneath.” In that case, the clouds could actually reduce the amount of heat that brighter ice would otherwise reflect away from the planet. The study did not try to measure that effect, but it could be an important subject for future research, he added. The guano effect lingers even after the birds leave the breeding areas. A month after they were gone, Boyer said ammonia levels in the air were still 1,000 times higher than the baseline. “The emission of ammonia is a temperature-dependent process, so it’s likely that once wintertime comes, the ammonia gets frozen in,” he said. “But even before the penguins come back, I would hypothesize that as the temperature warms, the guano starts to emit ammonia again. And the penguins move all around the coast, so it’s possible they’re just fertilizing an entire coast with ammonia.” Bob Berwyn, Inside Climate News 4 Comments

Designing human-centered AI products can be arduous.Keeping up with the overall pace of change isn’t easy. But here’s a bigger challenge:The wildly different paces of change attached to the key elements of AI product strategy, design, and development can make managing those elements — and even thinking about them — overwhelming.Yesterday’s design processes and frameworks offer priceless guidance that still holds. But in many spots, they just don’t fit today’s environment.For instance, designers used to map out and user-test precise, predictable end-to-end screen flows. But flows are no longer precisely predictable. AI generates dynamic dialogues and custom-tailored flows on the fly, rendering much of the old practice unhelpful and infeasible.It’s easy for product teams to feel adrift nowadays — we can hoist the sails, but we’re missing a map and a rudder. We need frameworks tailored to the traits that fundamentally set AI apart from traditional software, including:its capabilities for autonomy and collaboration,its probabilistic nature,its early need for quality data, andits predictable unpredictability. Humans tend to be perpetually surprised by its abilities — and its inabilities.AI pace layers: design for resilienceHere’s a framework to address these challenges.Building on Stewart Brand’s “Shearing Layers” framework, AI Pace Layers helps teams grow thriving AI products by framing them as layered systems with components that function and evolve at different timescales.It helps anticipate points of friction and create resilient and humane products.Each layer represents a specific domain of activity and responsibility, with a distinct pace of change.* Unlike the other layers, Services cuts across multiple layers rather than sitting between them, and its pace of change fluctuates erratically.Boundaries between layers call for special attention and care — friction at these points can produce destructive shearing and constructive turbulence.I’ll dive deeper into this framework with some practical examples showing how it works. But first, a brief review of the precursors that inspired this framework will help you put it to good use.The foundationsThis model builds on the insights of several influential design frameworks from the professions of building architecture and traditional software design.Shearing layers (Duffy and Brand)In his 1994 book How Buildings Learn, Stewart Brand expanded on architect Frank Duffy’s concept of shearing layers. The core insight: buildings consist of components that change at different rates.Shell, Services, Scenery, and Sets. (Frank Duffy, 1992).“…there isn’t any such thing as a building. A building properly conceived is several layers of longevity of built components.” — Frank DuffyShearing Layers of Change, from How Buildings Learn: What Happens after they’re built (Stewart Brand, 1994).Expanding on Duffy’s work, Brand identified six layers, from the slow-changing “Site” to the rapidly evolving “Stuff.”As the layers move at different speeds, friction forms where they meet. Buildings designed without mindful consideration of these different velocities tear themselves apart at these “shearing” points. Before long, they tend to be demolished and replaced.Buildings designed for resiliency allow for “slippage” between the moving layers — flexibility for the different rates of change to unfold with minimal conflict. Such buildings can thrive and remain useful for hundreds of years.Pace layers (Brand)In 1999, Brand drew insights from ecologists to expand this concept beyond buildings and encompass human society. In The Clock Of The Long Now: Time And Responsibility, he proposed “Pace Layers” — six levels ranging from rapid fashion to glacially-slow nature.Brand’s Pace Layers (1999) as sketched by Jono Hey.Brand again pointed out the boundaries, where the most intriguing and consequential changes emerge. Friction at the tension points can tear a building apart — or spur a civilization’s collapse–when we try to bind the layers too tightly together. But with mindful design and planning for slippage, activity along these boundary zones can also generate “constructive turbulence” that keeps systems balanced and resilient.The most successful systems survive and thrive through times of change through resiliency, by absorbing and incorporating shocks.“…a few scientists (such as R. V. O’Neill and C. S. Holling) have been probing the same issue in ecological systems: how do they manage change, how do they absorb and incorporate shocks? The answer appears to lie in the relationship between components in a system that have different change-rates and different scales of size. Instead of breaking under stress like something brittle, these systems yield as if they were soft. Some parts respond quickly to the shock, allowing slower parts to ignore the shock and maintain their steady duties of system continuity.” — Stewart BrandRoles and tendencies of the fast (upper) and slow (lower) layers. (Brand).Slower layers provide constraints and underpinnings for the faster layers, while faster layers induce adaptations in the slower layers that evolve the system.Elements of UX (Garrett)Jesse James Garrett’s classic The Elements of User Experience (2002) presents a five-layer model for digital design:Surface (visual design)Skeleton (interface design, navigation design, information design)Structure (interaction design, information architecture)Scope (functional specs, content requirements)Strategy (user needs, site objectives)Structure, Scope, and Strategy. Each layer answers a different set of questions, with the questions answered at each level setting constraints for the levels above. Lower layers set boundaries and underpinnings that help define the more concrete layers.Jesse James Garrett’s 5 layers from The Elements of User Experience Design (2002)This framework doesn’t focus on time, or on tension points resulting from conflicting velocities. But it provides a comprehensive structure for shaping different aspects of digital product design, from abstract strategy to concrete surface elements.AI Pace Layers: diving deeperBuilding on these foundations, the AI Pace Layers framework adapts these concepts specifically for AI systems design.Let’s explore each layer and understand how design expertise contributes across the framework.SessionsPace of change: Very fast (milliseconds to minutes)Focus: Performance of real-time interactions.This layer encompasses real-time dialogue, reasoning, and processing. These interplays happen between the user and AI, and between AI agents and other services and people, on behalf of the user. Sessions draw on lower-layer capabilities and components to deliver the “moments of truth” where product experiences succeed or fail. Feedback from the Sessions layer is crucial for improving and evolving the lower layers.Key contributors: Users and AI agents — usually with zero direct human involvement backstage.Example actions/decisions/artifacts: User/AI dialogue. Audio, video, text, images, and widgets are rendered on the fly (using building blocks provided by lower levels). Real-time adaptations to context.SkinPace of change: Moderately fast (days to months)Focus: Design patterns, guidelines, and assetsSkin encompasses visual, interaction, and content design.Key contributors: Designers, content strategists, front-end developers, and user researchers.Design’s role: This is where designers’ traditional expertise shines. They craft the interface elements, establish visual language, define interaction patterns, and create the design systems that represent the product’s capabilities to users.Example actions/decisions/artifacts: UI component libraries, brand guidelines, prompt templates, tone of voice guidelines, navigation systems, visual design systems, patterns (UI, interaction, and conversation), content style guides.ServicesPace of change: Wildly variable (slow to moderately fast)Focus: AI computation capabilities, data systems orchestration, and operational intelligenceThe Services layer provides probabilistic AI capabilities that sometimes feel like superpowers — and like superpowers, they can be difficult to manage. It encompasses foundation models, algorithms, data pipelines, evaluation frameworks, business logic, and computing resources.Services is an outlier that behaves differently from the other layers:• It’s more prone to “shocks” and surprises that can ripple across the rest of the system.• It varies wildly in pace of change. (But its components rarely change faster than Skin, or slower than Skeleton.)• It cuts across multiple layers rather than sitting between two of them. That produces more cross-layer boundaries, more tension points, more risks of destructive friction, and more opportunities for constructive turbulence.Key contributors: Data scientists, engineers, service designers, ethicists, product teamsDesign’s role: Designers partner with technical teams on evaluation frameworks, helping define what “good” looks like from a human experience perspective. They contribute to guardrails, monitoring systems, and multi-agent collaboration patterns, ensuring technical capabilities translate to meaningful human experiences. Service design expertise helps orchestrate complex, multi-touchpoint AI capabilities.Example actions/decisions/artifacts: Foundation model selection, changes, and fine-tuning. Evals, monitoring systems, guardrails, performance metrics. Business rules, workflow orchestration. Multiagent collaboration and use of external tools (APIs, A2A, MCP, etc.) Continual appraisal and adoption of new tools, protocols, and capabilities.SkeletonPace of change: Moderately slow (months) Focus: Fundamental structure and organizationThis layer establishes the foundational architecture — the core interaction models, information architecture and organizing principles.Key contributors: Information architects, information designers, user researchers, system architects, engineersDesign’s role: Designers with information architecture expertise are important in this layer. They design taxonomies, knowledge graphs, and classification systems that make complex AI capabilities comprehensible and usable. UX researchers help ensure these structures fit the audience’s mental models, contexts, and expectations.Example actions/decisions/artifacts: Taxonomies, knowledge graphs, data models, system architecture, classification systems.ScopePace of change: Slow (months to years)Focus: Product requirementsThis layer defines core functional, content, and data requirements, accounting for the probabilistic nature of AI and defining acceptable levels of performance and variance.Key contributors: Product managers, design strategists, design researchers, business stakeholders, data scientists, trust & safety specialistsDesign’s role: Design researchers and strategists contribute to requirements through generative and exploratory research. They help define error taxonomies and acceptable failure modes from a user perspective, informing metrics that capture technical performance and human experience quality. Design strategists balance technical possibilities with human needs and ethical considerations.Example actions/decisions/artifacts: Product requirements documents specifying reliability thresholds, data requirements (volume, diversity, quality standards), error taxonomies and acceptable failure modes, performance metrics frameworks, responsible AI requirements, risk assessment, core user stories and journeys, documentation of expected model variance and handling approaches.StrategyPace of change: Very slow (years)Focus: Long-term vision and business goalsThis foundation layer defines audience needs, core problems to solve, and business goals. In AI products, data strategy is central.Key contributors: Executive leadership, design leaders, product leadership, business strategists, ethics boardsDesign’s role: Design leaders define problem spaces, identify opportunities, and plan roadmaps. They deliver a balance of business needs with human values in strategy development. Designers with expertise in responsible AI help establish ethical frameworks and guiding principles that shape all other layers.Example actions/decisions/artifacts: Problem space and opportunity assessments, market positioning documents, long-term product roadmaps, comprehensive data strategy planning, user research findings on core needs, ethical frameworks and guiding principles, business model documentation, competitive/cooperative AI ecosystem mapping.Practical examples: tension points between layersTension point example 1: Bookmuse’s timeline troubles(Friction between Sessions and Skin)Bookmuse is a promising new AI tool for novelists. Samantha, a writer, tries it out while hashing out the underpinnings of her latest time-travel historical fiction thriller. The Bookmuse team planned for plenty of Samantha’s needs. At first, she considers Bookmuse a handy assistant. It supplements chats with tailored interactive visualizations that efficiently track character personalities, histories, relationships, and dramatic arcs.But Samantha is writing a story about time travelers interfering with World War I events, so she’s constantly juggling dates and timelines. Bookmuse falls short. It’s a tiny startup, and Luke, the harried cofounder who serves as a combination designer/researcher/product manager, hasn’t carved out any date-specific timeline tools or date calculators. He forgot to provide even a basic date picker in the design system.Problem: Bookmuse does its best to help Samantha with her story timeline (Sessions layer). But it lacks effective tools for the job (Skin layer). Its date and time interactions feel confusing, clumsy, and out of step with the rest of its tone, look, and feel. Whenever Samantha consults the timeline, it breaks her out of her creative flow.Constructive turbulence opportunities:a) Present feedback mechanisms that ensure this sort of “missing piece” event results in the product team learning about the type of interaction pothole that appeared — without revealing details or content that compromise Samantha’ privacy and her work. (For instance, a session tagging system can flag all interaction dead-ends during date choice interactions.)b) Improve timeline/date UI and interaction patterns. Table stakes: Standard industry-best-practice date picker components that suit Bookmuse’s style, tone, and voice. Game changers: Widgets, visualizations, and patterns tailored to the special time-tracking/exploration challenges that fiction writers often wrestle with.c) Update the core usability heuristics and universal interaction design patterns baked into the evaluation frameworks (in the Services layer), as part of regular eval reviews and updates. Result: When the team learns about a friction moment like this, they can prevent a host of future similar issues before they emerge.These improvements will make Bookmuse more resilient and useful.Tension point example 2: MedicalMind’s diagnostic dilemma(Friction between Services and Skeleton)Thousands of healthcare providers use MedicalMind, an AI-powered clinical decision support tool. Dr. Rina Patel, an internal medicine physician at a busy community hospital, relies on it to stay current with rapidly evolving medical research while managing her patient load.Thanks to a groundbreaking update, a MedicalMind AI model (Services layer) is familiar with new medical research data and can recognize newly discovered connections between previously unrelated symptoms across different medical specialties. For example, it identified patterns linking certain dermatological symptoms to early indicators of cardiovascular issues — connections not yet widely recognized in standard medical taxonomies.But MedicalMind’s information architecture (Skeleton layer) was tailored to traditional medical classification systems, so it’s organized by body system, conditions by specialty, and treatments by mechanism of action. The MedicalMind team constructed this structure based on how doctors were traditionally trained to approach medical knowledge.Problem: When Dr. Patel enters a patient’s constellation of symptoms (Sessions layer), MedicalMind’s AI can recognize potentially valuable cross-specialty patterns (Services layer). But these insights can’t be optimally organized and presented because the underlying information architecture (Skeleton layer) doesn’t easily accommodate the new findings and relationships. The AI either forces the insights into ill-fitting categories or presents them as disconnected “additional notes” that tend to be overlooked. That reduces their clinical utility and Dr. Patel’s trust in the system.Constructive turbulence opportunities:a) Create an “emerging patterns” framework within the information architecture (Skeleton layer) that can accommodate new AI-identified patterns in ways that augment, rather than disrupt, the familiar classification systems that doctors rely on.b) Design flexible visualization components and interaction patterns and styles (in the Skin layer) specifically for exploring, discussing, and documenting cross-category relationships. Let doctors toggle between traditional taxonomies and newer, AI-generated knowledge maps depending on their needs and comfort level.c) Implement a clinician feedback loop where specialists can validate and discuss new AI-surfaced relationships, gradually promoting validated patterns into the main classification system.These improvements will make MedicalMind more adaptive to emerging medical knowledge while maintaining the structural integrity that healthcare professionals rely on for critical decisions. This provides more efficient assistants for clinicians and better health for patients.Tension point example 3: ScienceSeeker’s hypothesis bottleneck(Friction between Skin and Services)ScienceSeeker is an AI research assistant used by scientists worldwide. Dr. Elena Rodriguez, a molecular biologist, uses it to investigate protein interactions for targeted cancer drug delivery.The AI engine (Services layer) recently gained the ability to generate sophisticated hypothesis trees with multiple competing explanations, track confidence levels for each branch, and identify which experiments would most efficiently disambiguate between theories. It can reason across scientific domains, connecting molecular biology with physics, chemistry, and computational modeling.But the interface (Skin layer) remains locked in a traditional chatbot paradigm — a single-threaded exchange with responses appearing sequentially in a scrolling window.Problem: The AI engine and the problem space are natively multithreaded and multimodal, but the UI is limited to single-threaded conversation. When Dr. Rodriguez inputs her experimental results (Sessions layer), the AI generates a rich, multidimensional analysis (Services layer), but must flatten this complex reasoning into linear text (Skin layer). Critical relationships between hypotheses become buried in paragraphs, probability comparisons are difficult, and the holistic picture of how variables influence multiple hypotheses is lost. Dr. Rodriguez resorts to taking screenshots and manually drawing diagrams to reconstruct the reasoning that the AI possesses but cannot visually express.Constructive turbulence opportunities:a) Develop an expandable, interactive, infinite-canvas “hypothesis tree” visualization (Skin) that helps the AI dynamically represent multiple competing explanations and their relationships. Scientists can interact with this to explore different branches spatially rather than sequentially.b) Create a dual-pane interface that maintains the chat for simple queries but provides the infinite canvas for complex reasoning, transitioning seamlessly based on response complexity.c) Implement collaborative, interactive node-based diagrams for multi-contributor experiment planning, where potential experiments appear as nodes showing how they would affect confidence in different hypothesis branches.This would transform ScienceSeeker’s limited text assistant into a scientific reasoning partner. It would help researchers visualize and interact with complex possibilities in ways that better fit how they tackle multidimensional problems.Navigating the future with AI Pace LayersAI Pace Layers offers product teams a new framework for seeing and shaping the bewildering structures and dynamics that power AI products.By recognizing the evolving layers and heeding and designing for their boundaries, AI design teams can:Transform tension points into constructive innovationAnticipate friction before it damages the product experienceGrow resilient and humane AI systems that absorb and integrate rapid technological change without losing sight of human needs.The framework’s value isn’t in rigid categorization, but in recognizing how components interact across timescales. For AI product teams, this awareness enables more thoughtful design choices that prevent destructive shearing that can tear apart an AI system.This framework is a work in progress, evolving alongside the AI landscape it describes.I’d love to hear from you, especially if you’ve built successful AI products and have insights on how this model could better reflect your experience.

Far before modern humans ever walked the Earth, our Homo erectus ancestors made arduous journeys to the present-day islands of Southeast Asia. Fossil remnants of H. erectus have been left all across this region, and now, two newly discovered skull fragments belonging to the species have added a new angle to their story. A study published in the journal Quaternary Environments and Humans reveals that the fossil remains were found after a marine sand extraction project in the Madura Strait, a stretch of water between the Indonesian islands of Java and Madura. By examining the fossils, archaeologists have opened a window into the lives of H. erectus who took advantage of low sea levels to spread across a now-submerged landmass 140,000 years ago. H. erectus Fossils on JavaAfter leaving Africa nearly 2 million years ago, H. erectus trekked all the way through Asia and eventually hit the Southeast Asian islands closer to 1.5 million years ago. Fast-forward to the late 19th century, and the first set of H. erectus fossils was found by Dutch scientist Eugène Dubois on Java, enshrined in archaeological history as the Java Man. But with Java surrounded by water in modern times, one may wonder, how did H. erectus land there in the first place? In the ancient past, this part of the world was much different than it is today. Millions of years ago, a landmass called Sundaland connected islands like Bali, Borneo, Java, and Sumatra. Sundaland was exposed during glacial periods when sea levels were low, forming a land bridge that paved the way for human migration flows at various points in history. This is how H. erectus and other species could reach Java. Rare Vertebrate FossilsThe new fossils shed light on Javanese H. erectus much later in their existence, around 140,000 years ago. Researchers involved with the study say that vertebrate fossils have never been found in the area that was once Sundaland, now submerged in the ocean. “This makes our discoveries truly unique,” said Harold Berghuis, an archaeologist at Leiden University, the Netherlands, in a statement. “The fossils come from a drowned river valley, which filled up over time with river sand. We have been able to date the material to approximately 140,000 years ago. That was the penultimate glacial period. Large parts of the northern hemisphere were covered by glaciers, and so much water on Earth was stored in ice caps that the global sea level was 100 metres lower than today.”The fossils show that H. erectus living on Java at the time dispersed throughout the lowlands of Sundaland when the sea level had receded enough. They would have traveled along river systems such as the Brantas and Solo Rivers, finding edible plants and shellfish. Read More: Who Was Homo Soloensis, the “Solo Man?”The Extinction of H. erectusThe researchers say that Javanese H. erectus hunted bovids (the family that includes cattle and buffalo), and potentially learned hunting practices through contact with more modern human species living on the Asian mainland. The final survivors of the entire H. erectus population were living in Java at the time of their death. Homo erectus soloensis (or the Solo Man), a subspecies of H. erectus, is believed to have lived along the Solo River from around 117,000 years to 108,000 years ago, marking the last known record of H. erectus. The extinction of the species may have occurred as a result of a changing climate that caused Java to morph from an open woodland environment into a rainforest.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

For years, archeologists assumed the ancient Homo erectus population that lived on present-day Java existed in general isolation from nearby island relatives. However, a pair of fossilized skull fragments recently found off the Javanese coast are helping experts recontextualize the lives of the region’s H. erectus populations as they existed around 140,000 years ago. According to a study published May 15 in the journal Quaternary Environments and Humans, life for the Javanese H. erectus wasn’t always as lonely as we thought. Today, Indonesia consists of multiple islands between Asia and Australia, but that hasn’t always been the case. Beginning roughly 2.6 million years ago, the larger area has occasionally existed during periods of lower ocean levels as a larger, unified lowland landmass known as Sundaland. While H. erectus fossils have previously been found on Java itself, none were known to exist further outward in areas like the Madura Strait, which separates the islands of Madura from Central Java.

Map data: GEBCO and ALOS / Credit: Quaternary Environments and Humans That all changed thanks to over 176.5 million cubic feet of sand. The massive amount of sediment was dredged over 2014 to 2015 as part of an Indonesia land reclamation project, but it soon became clear that the sand also contained valuable historical remains. Scouring the material ultimately yielded around 6,000 fossil specimens from ancient fish, reptiles, and mammals–including the unexpected pair of H. erectus skull fragments. According to Harold Berghuis, study co-author and an archeologist at Leiden University in the Netherlands, their team’s discoveries are “truly unique.” “The fossils come from a drowned river valley, which filled up over time with river sand [dating to] approximately 140,000 years ago,” he said in an accompanying statement. Berghuis described that era as the “penultimate glacial period.” Earth’s Northern Hemisphere was so populated with glaciers, that the global sea level averaged nearly 1,100 feet lower than it does today. Because of this, Sundaland in the time of H. erectus greatly resembled the African savannah of today—largely dry grassland broken up by major rivers surrounded by narrow strips of forests. “Here they had water, shellfish, fish, edible plants, seeds and fruit all year round,” said Berghuis. Sundaland also featured a variety of animals, including multiple species of elephants, rhinos, and crocodiles. Strikingly, the bones the team found even have evidence of butchery by H. erectus. “Among our new finds are cut marks on the bones of water turtles and large numbers of broken bovid bones, which point to hunting and consumption of bone marrow,” Berghuis added. While this contrasts with earlier Javanese H. erectus populations, it had previously been documented in more modern human species who lived on the Asian mainland. According to the study’s authors, this indicates that Sundaland’s H. erectus may have learned those techniques from them. “This suggests there may have been contact between these hominin groups, or even genetic exchange,” theorized Berghuis.
