How Rapa Nui Lost a Tree, Only to Have It Sprout Up Elsewhere

News Feed
Tuesday, March 26, 2024

The tree that goes by toromiro has been a fragile expat for more than a half-century. Little Sophora toromiro, is far from home, no longer present on Rapa Nui, the Pacific island where it evolved. Also known as Easter Island, or Isla de Pascua in Spanish, Rapa Nui is a speck of land in the Pacific, 2,200 miles from the west coast of Chile. The tiny island encompasses just 63 square miles, and it is quite flat, with a maximum elevation of less than 1,700 feet. The last date of the toromiro’s tenure on Rapa Nui is uncertain. Some accounts say it went extinct in the wild in 1960. Others say that it was gone by 1962, when Karl Schanz, a German meteorologist, clambered down to see the tree in the crater where it had last been spotted, and it was gone. Was it removed? Did it die, tip over and return to the earth? We will never know. Although the toromiro is gone from Rapa Nui, it survives elsewhere through luck—and pluck. Over the past century, the intermittent collecting of the toromiro’s seeds and their replanting in mainland locations have given the species purchase elsewhere. Each tree is a member of a small diaspora, with only a handful surviving in about a dozen different public and private botanical gardens around the world. This is a story of survival, persistence and, perhaps in some ways, dumb luck—a tree in decline that was rescued and whose seeds were sent to other places. Mention Easter Island to almost anyone, and if they’ve heard of it, they’ve likely heard of its statues. Imprinted in the popular imagination are its enigmatic, massive stone sculptures, or moai. Curious investigators have speculated for more than two centuries about how more than 900 of these mysterious statues—the largest being more than 30 feet tall and weighing over 80 tons—might have been moved to locations around the island, traveling miles from the site where they were quarried. The toromiro, though, is an invisible tree on the island, its story known to very few, and its existence marked more by its absence than its presence. The tree does have many close relatives. The Sophora genus is speciose, as biologists say—a crowded taxon consisting of some 60 different species, including a dozen closely related oceanic ones scattered across the Pacific. The toromiro is more of a shrub than a tree, and none of its close relatives is large—at least from descriptions recorded over the past century. The northernmost outpost for the Sophora genus is in Hawaiʻi, where Sophora chrysophylla is the primary food source for the palila, a critically endangered honeycreeper. Without S. chrysophylla, known as mamane in Hawaiian, the palila would not have survived the last century as its range dwindled. The subterranean pollen record reveals that the toromiro was abundant across much of Rapa Nui, where many other now-extinct plants also thrived. Paleobotanical evidence shows that the tree’s presence on the island dates back at least 35,000 years. Its seeds are both buoyant and salt-resistant, and they probably first arrived by water, floating onto the island, probably from another Pacific island, and then it did what species do: continued its evolutionary journey in a new place to become the tree we know today. But even before the toromiro disappeared from the island, it had been without a lot of endemic companions. Fewer than 30 indigenous seed-bearing plant species have survived on Rapa Nui to the present day, and weeds, along with naturalized, cultivated shrubs, are now the main plants growing there. The toromiro did not disappear precipitously but experienced a protracted decline. Humans arrived in Rapa Nui around the 12th century, probably not long after Polynesians reached the Hawaiian archipelago. Some hundreds of years after humans’ arrival, the island experienced a painful drop in biodiversity, and its carrying capacity plummeted as the native palm forests disappeared, replaced by grasslands. Food grew scarce, and occupants fled, thinning down to around 100 Rapa Nui at one point in the 19th century. In his deterministic 2005 book Collapse: How Societies Choose to Fail or Succeed, Jared Diamond claimed the occupants were lousy land managers. His analysis of why Rapa Nui became denuded of its plant life is now out of date, as later studies have revealed the island’s complexities. To sketch the story of the weakening grip of native plant life on Rapa Nui as a predictable story of human arrogance intersecting with a small, remote and evolutionarily vulnerable spit of land is tempting, but the tale is more nuanced than that. Natives there recorded centuries-old histories of careful but intermittent conservation strategies. Some scholars have asserted that the Little Ice Age stressed resources on the island between the 16th and 19th centuries, leading to the disappearance of palms and other important contributors to the islanders’ activities and well-being. Others have pointed to prolonged droughts, while still others have continued to argue that humans were highly complicit in the island’s declining biodiversity. Were groves of palm trees decimated to create systems for rolling the giant stone carvings from quarry to coastline, where most of them have sat for many hundreds of years? Perhaps. However the palms disappeared, their loss seems to have been a factor in the tumbling downturn of the island’s other trees, including the toromiro. The palms had made up the great majority of Rapa Nui’s tree cover, some 16 million trees that blanketed about 70 percent of the island. Some controversy remains about what particular species of palm flourished, but many believe it was Paschalococos disperta, the Rapa Nui palm. Jaime Espejo, a Chilean botanist who’s written extensively about the toromiro, noted that it probably lived in the undergrowth of the palm, lodged in an ancient ecosystem that no longer exists. Paleobotanists and archaeologists studying the island spotted the widespread loss of the palms in their investigations. At the same time, they found that the number of fish bones found in waste middens around the island dropped as fishing boats could no longer be constructed in large numbers from trees. The loss of access to fish must have been a devastating turn, because the human residents’ main proteins came from the sea. Soil erosion, likely exacerbated by deforestation and agriculture, led to further losses of the tree. Hooved animals, arriving with European explorers in the 18th century, were also certain culprits in the toromiro’s decline and disappearance. In Hawaiʻi, sheep consume that archipelago’s species of Sophora. Another creature implicated in the destruction of much of both Rapa Nui’s and Hawaiʻi’s plant life was the Polynesian rat (Rattus exulans), as well as the bigger ship rat (Rattus rattus) and Norwegian rat (Rattus norvegicus). These rats, landing on new island homes and able to reproduce quickly, found abundant food in the form of native seeds, plants and invertebrates—and no predators. They laid waste to plant life with shocking speed. An aerial view of a toromiro in Barcelona, Spain Daderot via Wikimedia CC0 Early European accounts and pollen records tell us that by about 1600, forests in the island’s craters had disappeared, and, with that, the toromiro declined into long-term scarcity and then extirpation. The New Zealand anthropologist Steven Fischer has noted that the last forest was probably cut for firewood around 1640, making wood the most valuable commodity on the island. Driftwood became precious. So scarce was wood, Fischer observes, that the pan-Polynesian word rakau, meaning “tree,” “timber” or “wood,” came to mean “riches” or “wealth” in the old Rapa Nui language—a meaning not present in any other use of the word elsewhere in Polynesia, including in Tahiti, Tonga, Hawaiʻi and New Zealand. It’s ironic that after the deforestation of the island’s trees, new linguistic meanings sprouted out of the island’s impending botanical doom. Amid these centuries-long difficulties, but long before the toromiro disappeared, a wood-based culture thrived. The Rapa Nui had a particular passion for carving; beyond their giant stone statues, they favored the toromiro for its durable and fine-grained wood and reddish hue. Although primarily used for ritual objects, the toromiro was also serviceable for building material in houses, household utensils, statuettes and paddles. These artifacts survive in museums around the world. Some of them are hundreds of years old, and they might provide unexpected addenda to our understandings of the tree’s deeper history, offered up through dendrochronological analysis. Studying the annual growth rings in the wood could provide details we lack: the pace of growth of the wood, environmental pressures acting on the tree, its ultimate size and many of the other clues revealed through laboratory work with wood specimens. Part of our lack of knowledge about the tree’s wood is because it has always been uncommon on the island, at least since Western contact. Rapa Nui came with inherent geographic disadvantages for plant survival, including few sheltered habitats with steep hillsides or deep ravines in which toromiro could remain hidden away from humans. The three volcanic craters on the island are the only such hiding places. In 1911, the Chilean botanist Francisco Fuentes noted that the toromiro was rare, only to be found in Rano Kau, the largest of the craters. The Swedish botanist Carl Skottsberg, who also worked on Hawaiian flora, visited Rano Kau in 1917 and found only a single specimen. A compelling global exploration of nature and survival as seen through a dozen species of trees. The final contact with the tree on its native soil occurred when the Norwegian explorer Thor Heyerdahl collected seeds from the last surviving example. This was likely the same tree that Skottsberg had found in the shelter of Rano Kau. The egg-shaped crater is about a mile across and has its own microclimate, largely out of the winds and weather, and protected from grazing ungulates by a rock formation. Foot traffic remained down in the last century, as little else lives in the crater that can be harvested or cut down. Innumerable swampy pockets of water make the area difficult to traverse. A beautiful, multicolored, shallow lake of open water and floating mats of peat cover much of the bottom of the crater. There, the tiny toromiro held on. Heyerdahl, who had already been traveling around the Pacific Ocean in the 1940s, became famous, or infamous, for floating a radical new theory: that the islands in the Pacific had been populated initially by American Indians from the mainland of South America, rather than by people from Asia or from other Polynesian islands. In 1947, he launched an expedition with a primitive raft named Kon-Tiki and made a 5,000-mile journey, heading west from Peru. What’s often lost in the voluminous writings about Heyerdahl and his oceanfaring obsessions was his interest in Rapa Nui. Björn Aldén, a Swedish botanist with the Gothenburg Botanical Garden, became friends with Heyerdahl and has worked to return the toromiro to its native land. In a letter to Björn, Heyerdahl decried the “tankelöse treskjaerere,” or “thoughtless woodcutters.” He noted how good it felt to have helped to save the species by collecting a handful of seeds that hung from the tree’s sole remaining branch. Heyerdahl couldn’t recount the exact date, or even the year, but thought it was sometime in late 1955 or early 1956. Heyerdahl handed the seeds off to paleobotanist Olaf Selling in Stockholm. They went to Gothenburg from there. Locals have a strain of national pride in Gothenburg for their role in the tree’s cultivation and survival. But recently, researchers in Chile discovered that another botanist preceded Heyerdahl in getting seeds off the island. Efraín Volosky Yadlin, an Argentinian-born immigrant, participated in the first agronomic studies on Rapa Nui. Sent there by the Chilean Ministry of Agriculture in the early 1950s, Volosky Yadlin collected seeds, apparently from the same tree that Heyerdahl would come upon a few years later, and proceeded to carry out his own propagation tests on the toromiro. Now the tree remains far afield, surviving in about a dozen locations around the world, mostly in botanical gardens including in Chile, in London and in southern France. Ultimately, researchers want to return the toromiro to Rapa Nui. But the tree still confronts challenges to surviving on its native ground, including a lack of genetic diversity and degraded soil on Rapa Nui. Past efforts to reestablish the tree have failed, but botanists are doing their best to overcome these hurdles. More studies will help researchers understand just what it will take to help the tree take root back on Rapa Nui and successfully end a long and difficult voyage.

Before the toromiro disappeared from the island, at least two men grabbed seeds from the last remaining plant and brought them home

What This Week's Winter Wallop Means for Farmers Across the U.S.

This week’s winter wallop across the U.S. means different things to farmers in different places

Farmers always watch the weather, but depending on where they're located and what they produce, winter always presents mental challenges for growers, said Carolyn Olson, an organic farmer in southwestern Minnesota who is also vice president of the Minnesota Farm Bureau Federation Board of Directors.Producers know that the timing and amount of winter moisture affect farming conditions for the rest of the year. It's also a time for planning ahead — something becoming increasingly difficult as climate change ramps up variability in snowfall, rainfall and other weather conditions that can make or break an operation. “They’re doing that stressful part of making those decisions on how they’re going to farm this year, what they’re going to grow,” Olson said. “It’s just a lot of pressure on agriculture at this time of the year." Livestock producers dealing with ‘generational storm’ Biting wind and big drifts from almost a whole year's average snowfall in a single storm are hitting farmers in some parts of Kansas “in ways that we haven’t seen in this area for a very, very long time, potentially a lifetime,” said Chip Redmond, a meteorologist at Kansas State University who developed an animal comfort tool. It includes an index of heat and cold that a farmer can use — along with their knowledge of their animals' age, coat, overall health and so forth — to watch for situations when they may need to get animals out of dangerous areas.The risk is real: Calves, especially, can die when temperatures slip below zero. And so much snow in rural areas can keep farmers from reaching herds with food and water, Redmond said.That means preparing by moving animals and having a plan to care for them ahead of time is key — which is harder due to the unpredictability of climate change. And not having the right experience or infrastructure to prepare is “really, really stressful on producers,” Redmond said. Reprieve for some typically snowy areas The storm missed some states further north like Iowa and Minnesota that are generally more accustomed to snow. Stu Swanson, president of the Iowa Corn Growers Association, said that eases tasks like moving grain and working with livestock. He added that without snow cover, the ground is more likely to freeze and thaw in a way that could benefit soils. Two years of drought followed by torrential rains last spring created tire ruts and compaction from farm machinery in some places, he said. He hopes that without as much snow, the freeze-thaw cycle will loosen up the soil and farmers may get the added bonus of some pests dying off before the spring.“We don’t have any growing crop now, so really temperature doesn’t matter. We look forward to a good freeze,” Swanson said. ‘Feast or famine’: Extremes and unpredictability worry some farmers The lack of snow is a greater concern farther north in some parts of Minnesota, where producers do have winter crops like alfalfa or winter wheat. Reliable snow cover is important in those areas because it insulates soil from cold. A few of inches of snow on top of a field can keep winter wheat’s crown (which is still underground this time of year to withstand the winter) at 28 degrees Fahrenheit (minus 2 Celsius) even if the air temperature is as low as minus 40 Fahrenheit (minus 40 Celsius), said Jochum Wiersma, an extension professor at the University of Minnesota.“There’s not a lot you can do, unfortunately,” when ice breaks a plant's crown, said Martin Larsen, who grows alfalfa in addition to other crops like corn in southeastern Minnesota. He's concerned about the long-term trends, too — he pointed out last year's likely record warmth — and said he noticed the lack of snow cover in his region then, too.“We were so dry going into last spring and we were in the field almost a month before we normally do. I would say that concern exists this year as well," Larsen said.Gary Prescher, who has been farming a small grain operation for about 50 years in south-central Minnesota, said he's noticed more variability over the past six to 10 years. That's changing his long-term philosophy on the farm. He said he wants to make sure his operation can handle more extreme weather events, and that excess heat, cold, dryness, wetness or wind have “forced some changes out here for me and my neighbors.”“If you’re just looking at averages, it’s very deceiving,” he said. “It's either all or none.”The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

Monarch butterflies are in decline in NZ and Australia – they need your help to track where they gather

Citizen scientists are called on to help with tagging monarch butterflies and find out why their numbers are dropping.

Kathy Reid, CC BY-SAMonarch butterflies (Danaus plexippus) appear to be declining not just in North America but also in Australiasia. Could this be a consequence of global change, including climate change, the intensification of agriculture, and urbanisation? We need more citizen scientists to monitor what is really going on. Insect populations, even species that seemed impervious, are in decline globally. Monarch butterflies exemplify the problem. Once a very common species, numbers have declined dramatically in North America, engendering keen public interest in restoring populations. The monarch butterfly is an iconic species. It is usually the species people recall when drawing a butterfly and observations are shared frequently on the online social network iNaturalist. This is partly because monarch images are used in advertising, but the butterflies are also a species of choice for school biology classes and television documentaries on animal migration. Monarchs in the southern hemisphere Monarchs expanded their range to reach Australia and New Zealand during the mid-1800s. Kathy Reid, CC BY-SA The monarch butterfly’s ancestral home in North America is noted for an annual mass migration and spectacular overwintering of adults in fir forests in a few locations in Mexico, at densities of 50 million per hectare, and at multiple sites in Southern California. These sites are monitored to track the decline. What is not as well known is that this butterfly greatly extended its range, spreading across the Pacific in the mid-1800s to reach Australia and New Zealand by riding on storms that blew in from New Caledonia. The species is now part of the roadside scene in these countries and was once known as “the wanderer” – reflecting its propensity to fly across the landscape in search of milkweed plants (known as swan plants in New Zealand). In both countries, monarchs lay eggs on introduced milkweed species for their caterpillars to feed and develop. They take up the plant’s toxins as part of their own defence. Interestingly, in their expanded range in the southern hemisphere, monarchs have adapted their migration patterns to suit local conditions. They have established overwinter sites – places where large numbers of adults congregate on trees throughout winter. Need for citizen science In Australia, the late entomologist Courtenay Smithers organised people to report these sites and participate in a mark-recapture programme. Essentially, this involves attaching a small unique identifying tag to the wing, noting the age and condition of the butterfly and the date and location of capture. If the same individual is then recaptured sometime later and the information shared, it provides valuable data on survival and the distance and direction it moved, and even population size. This volunteer tagging programme enabled many aspects of the monarch’s ecology in Australia to be documented, but it was discontinued a few years ago. Moths and Butterflies Australasia now hosts the butterfly database and has become an umbrella group for encouraging everyone with a mobile phone to get involved and report and record sightings. Monarchs have established wintering sites in New Zealand and Australia. Kathy Reid, CC BY-SA A similar programme is run in New Zealand by the Moths and Butterflies of New Zealand Trust. Monarch overwintering sites and local breeding populations have been documented over the years. Alas, these data sets have been short term and haphazard. What is intriguing is that populations appear to have declined in Australia and New Zealand, perhaps reflecting climate variability, expanding cities gobbling up local breeding habitats, and the intensification of agriculture. What we need is reliable long-term data on adult numbers. Hence the call to reinvigorate interest in mark-recapture and reporting. We need the help of people who love the outdoors and love the monarch butterfly to become citizen scientists. Citizen scientists are needed to help with tagging monarch butterflies. Anna Barnett, CC BY-SA The Moths and Butterflies of New Zealand Trust is asking individuals, groups and schools to tag monarch butterflies late in the autumn when the butterflies head for their overwintering habitat. This is a great project for schools, involving students in real science and addressing an environmental issue. Each tag has a unique code. A computer system calculates the distance the monarch has flown and the time it took to get there. This information can then be collated with weather data to get a clearer picture of what is happening. We hope people will spot tagged monarchs in their gardens and record where the butterfly was sighted, together with its tag number.

AI use cases are going to get even bigger in 2025

Over the past two years, generative AI has dominated tech conversations and media headlines. Tools like ChatGPT, Gemini, Midjourney, and Sora captured imaginations with their ability to create text, images, and videos, sparking both excitement and ethical debates. However, artificial intelligence goes far beyond generative AI—which is just a subset of AI—and its associated models. AI’s real promise lies in its ability to address complex challenges across diverse industries, from military technology to cybersecurity, medicine, and even genome sequencing. As we move into 2025 and beyond, the question isn’t whether AI use cases will expand—it’s how big and transformative they’ll get. MILITARY TACTICS AND INTELLIGENCE Few sectors stand to gain more from AI advancements than defense. “We are witnessing a surge in applications like autonomous drone swarms, electronic spectrum awareness, and real-time battlefield space management, where AI, edge computing, and sensor technologies are integrated to enable faster responses and enhanced precision,” says Meir Friedland, CEO at RF spectrum intelligence company Sensorz. Friedland notes that recent conflicts, particularly in Ukraine and across the Middle East, have highlighted critical vulnerabilities in military operations, from tactical to strategic levels—a factor he says will drive the adoption of AI use cases in the military. While Axios said in April that AI hit trust hurdles with the U.S. military, Friedland notes that with the rise of global tensions and defense budgets at an all-time high, “we can expect significant investment in AI to maintain a combat edge.” For Friedland, the defense sector’s growing embrace of innovation from startups like Palantir and Anduril reflects how AI is going to increasingly change things across the global defense sector. CRACKING THE CODE OF LIFE The healthcare sector is witnessing a sharp rise in AI-driven innovation, especially in precision medicine and genome sequencing, transforming how diseases are understood and treated. For many years, scientists and medical professionals have been trying to understand human DNA in an attempt to crack the code that powers life as we know it. Now, with new AI models like GROVER, they have a real chance at getting closer to that goal, Science Daily reports. “AI is transforming genome sequencing, enabling faster and more accurate analyses of genetic data,” Khalfan Belhoul, CEO at the Dubai Future Foundation, tells Fast Company. “Already, the largest genome banks in the U.K. and the UAE each have over half a million samples, but soon, one genome bank will surpass this with a million samples.” But what does this mean? “It means we are entering an era where healthcare can truly become personalized, where we can anticipate and prevent certain diseases before they even develop,” Belhoul says. Genome banks, powered by AI, are facilitating the storage and retrieval of vast amounts of genetic data, which can be analyzed to identify patterns and predispositions to certain diseases. Beyond diagnostics, AI is playing a pivotal role in drug development, accelerating the discovery of therapies for complex diseases. By analyzing genetic mutations and environmental factors, AI enables researchers to design treatments tailored to individual patients. “These tools are not only improving outcomes but also reducing costs and timelines associated with traditional medical research,” says Belhoul. BUSINESS COMMUNICATION INTELLIGENCE Today, businesses swim in a vast ocean of applications—spanning email, messaging apps like WhatsApp and iMessage, and collaboration platforms like Microsoft Teams—that eventually make communication fragmented and often get important details lost in silos. But AI agents like LeapXpert’s patented Maxen are solving this challenge by combining external messaging channels with enterprise platforms to deliver what Dima Gutzeit, founder and CEO at LeapXpert, describes as “communication intelligence.” While Maxen is similar to Microsoft Copilot—which works only within the Microsoft product suite for now—it’s differentiated in its ability to integrate with multiple communications platforms, including WhatsApp, iMessage, and Microsoft Teams. Gutzeit explains that Maxen is an extension of the LeapXpert Communications Platform (which unifies and governs communication channels) and uses AI to provide relationship managers with real-time insights into client interactions. While that’s commendable, he notes that we haven’t even begun to scratch the surface of how AI will transform business communication. “2025 will see the rise of AI assistants tailored for enterprise needs, focusing on unifying communication data and driving actionable insights. Compliance and security AI will evolve further, flagging suspicious activity in real time and reinforcing trust in digital interactions,” Gutzeit says. AI’s role in business communication isn’t just about boosting efficiency. It’s also helping enterprises navigate the growing complexity of data governance and regulatory compliance. For Gutzeit, the future of AI in communication will combine privacy-first AI, compliance, and actionable insights, enabling businesses to thrive in a digitally interconnected world. AI-POWERED CYBERSECURITY OPERATIONS AI operates on both the offensive and defensive sides of the cybersecurity equation. One classic example is how cybercriminals used AI-generated deepfake technology to impersonate a company executive in Hong Kong, tricking him into transferring several millions of U.S. dollars. But in response to such threats, companies are deploying AI-driven anomaly detection tools like Darktrace and Vectra AI that monitor network traffic to detect and respond to irregular patterns. Alex Yevtushenko, CEO at Salvador Technologies, highlights the dual nature of AI in this space: “On the one hand, AI enables expansive behavioral analysis and anomaly detection, improving efficiency and speeding up threat detection. On the other, cybercriminals are leveraging AI to launch more sophisticated attacks.” A growing and worrisome trend is the use of AI for polymorphic malware—a type of malware that shapeshifts its codes, making it difficult to detect. Attackers are also deploying AI for large-scale phishing campaigns, voice cloning, and social engineering attacks. “National and other critical infrastructures, often reliant on legacy systems, are particularly vulnerable,” Yevtushenko warns. AI’s ability to automate malicious code generation and exploit vulnerabilities amplifies these risks. Yevtushenko emphasizes the importance of resilience strategies to combat these threats, noting that organizations, especially critical infrastructure operators and industrial enterprises, must invest in robust recovery systems that enable rapid restoration of operations. Salvador Technologies, for example, offers a platform that ensures operational continuity and facilitates rapid recovery, bypassing traditional protocols to minimize downtime. Speaking about major AI trends to expect in the coming year, Yevtushenko says that 2024 has illustrated that “AI, although not a technology that just emerged, is a hugely useful tool that can become a ‘game changer’ in many fields.” He says that in 2025 “we will see more and more AI-based systems and tools in everyday cybersecurity-based operations, empowering business decision-makers to make the right kind of decisions with the ultimate goal to increase overall security.” WHAT LIES AHEAD? The potential for AI extends far beyond the use cases dominating today’s headlines. As Friedland notes, “AI’s future lies in multi-domain coordination, edge computing, and autonomous systems.” These advancements are already reshaping industries like manufacturing, agriculture, and finance. In manufacturing, for example, AI-powered robotics is enhancing productivity and reducing waste by optimizing workflows. Take Machina Labs, which uses the latest advances in robotics and AI to build the next generation of factories for the manufacturing industry. Meanwhile, in the agricultural field, precision AI tools are helping farmers monitor crop health, predict yields, and conserve resources. A great example is CropX, which uses AI-powered algorithms to aggregate data from the soil and sky, then transform it into useful insights that help farmers monitor the health of their fields and crops. In finance, AI is improving fraud detection, enabling smarter investment strategies, and automating routine tasks, with companies like CertifID, Hawk AI, Riskified, and others using AI to detect and mitigate fraud at scale. As we move further into the decade, the consensus by many experts is that AI will increasingly take over routine tasks, freeing human experts to focus on complex challenges that require nuanced decision-making. Emerging technologies like quantum computing and hardware acceleration are also expected to supercharge AI’s capabilities, enabling more powerful models and faster decision-making processes. “AI will become more useful for decision-making in the C-suite,” says Belhoul, who also predicts that “we may see the first AI board member of a Fortune 500 company next year.”

What Bird Flu Means for Milk

On Wednesday, California became the first state to issue a declaration of emergency regarding the avian flu (H5N1).

On Wednesday, California became the first state to issue a declaration of emergency regarding the avian flu (H5N1). That same day, the Centers for Disease Control and Prevention (CDC) confirmed the first severe case of the flu in a human on US soil and outbreaks in cow herds were detected in Southern California. Still, the threat to humans is low according to the CDC. The agency has traced most human infections back to those handling livestock, and there’s been no reported transmission between people. “I have dairies that are never coming back from this.” But for cows and the dairy they produce, it’s a different story. This year was the first time the flu was detected in cows in the US, and it has ripped through many Western states’ dairy farms with startling speed. Since March, the virus has been found in cow herds of 16 states. For the last few months, infected herds have largely been concentrated in California—the state that makes up about 20 percent of the nation’s dairy industry. Last week, Texas, another one of the nation’s top dairy producing states, saw the reappearance of bird flu after two months without a detected outbreak. In the industry hit hardest by bird flu, the poultry industry, the virus’ spread has resulted in the culling of entire flocks which has lead to higher egg prices on supermarket shelves. Will milk and butter prices soon go the same route? And how worried should you be about consuming dairy? How exactly does bird flu affect dairy cows? Some farmers are first identifying outbreaks in their herds through the color and density of the milk, in what they are coining “golden mastitis,” according to Milkweed, a dairy news publication. As early studies by University of Copenhagen researchers found, the virus latches onto dairy cows mammary glands, creating complications for the dairy industry beyond just the cow fatalities. The virus is proving deadly to cows. According to Colorado State University Professor Jason Lombard, an infectious disease specialist for cattle, the case fatality rates based on a limited set of herds was zero to 15 percent. But California saw an even higher rate of up to 20 percent during a late summer heatwave in the states Central Valley. It was a warning for how the rising number of heatwaves and temps across the country could result in deadlier herd outbreaks in upcoming summers.  For some of the cows that survived, there was a dip in their dairy production of around 25 percent according to multiple experts I spoke with. As a farmer told Bloomberg News, some of the cows aren’t returning to full production levels, an indication of longer lasting effects of the virus. It’s a finding experts are seeing in other parts of the US, too. According to Lombard, this may be due to the severity of the virus in the cow. According to reporting in Milkweed, there may also be “long-tail” bird flu impacts on a cow’s dairy production, health, and reproduction. Additional research is likely needed to understand the extent of these potential longterm effects of the virus and whether they could spell trouble ahead for recovering farms.   A spokesperson with the California Department of Food and Agriculture told Mother Jones, “it’s too soon to know how production has been impacted.” How is this impacting farms and farm workers? As of today, more than half of the people who’ve contracted H5N1 are dairy farmworkers, according to the CDC. This population is particularly vulnerable because they are often the ones handling milking or milking equipment which can lead to spreading the virus. The CDC is recommending employers take steps to reduce their workers’ exposure to the virus by creating health and safety plans. The CDC is working with organizations like the National Center for Farm Worker Health to expand testing, PPE availability, and training. According to Bethany Alcauter, a director at the organization, ensuring dairy farmworkers have access to testing is a tricky situation. The 100,000-some workforce faces barriers to accessing health care and testing, such as an inability to take paid-time off to get themselves tested if they are sick. And the system depends on the producer to decide to bring in the health department to oversee potential outbreaks within herds and staff, which doesn’t always happen because there’s no government mandate. “It’s all recommendations and kindness—that’s what we’re running on. It’s not regulation and enforcement.” “It’s all recommendations and kindness—that’s what we’re running on,” Alcauter says. “It’s not regulation and enforcement.” She believes the testing infrastructure could be strengthened by “recognizing that farm workers can be public-health first responders if they have the knowledge and the access to the right contacts, in the right system.” Outside of navigating farmworker health, farmers face economic impacts when the virus spreads through their herds. “What you’re losing at the end of the day is revenue for your farm when it rolls through,” says Will Loux, vice president of economic affairs for the National Milk Producers Federation. “Depending on the financial situation of an individual farm it can certainly be devastating.”  There are a handful of variables and factors that shape the financial losses of a dairy hit with an outbreak. Luckily, agriculture economist Charles Nicholson at the University of Wisconsin-Madison and some colleagues created a calculator to estimate this financial impact of a bird flu outbreak. Based on Nicholson’s estimates for California, a typical farm of 1500 cattle will lose $120,000 annually. For context, this is about $10,000 more than the median household income of a dairy farmer. Based on those estimates, that would mean California’s farmers have collectively lost about $80 million at most due to avian flu so far. The US Department of Agriculture is providing support for farmers who are impacted by H5N1 outbreaks. In reviewing a few herd datasets in Michigan, Phillip Durst, a dairy and cattle expert, noted that about half a year after an outbreak, herds were producing around 10 percent less than before. Not only do farmers face massive short term losses, they also struggle to return to full capacity again. And, there are high costs associated with putting resources into taking care of sick animals too.  Even strong diaries that had “tip top” biosecurity measures, or comprehensive environmental protection measures in place, are shutting down, according to Anja Raudabaugh, CEO of Western Untied Dairies, a trade organization overseeing farms across California. “I have dairies that are never coming back from this,” Raudabaugh says. “This was just so cataclysmic for them. They’re not going to be able to get over that loss in production hump.” There is some hope around the corner. A vaccine for cows, which the USDA claims is in the works, could help stop the spread and protect remaining uninfected herds. “Until we have a vaccine that we can inoculate them with at an early age, we have no choices except to hope that herd immunity sets in soon,” Raudabaugh says. What’s the effect on milk? In June, the US dropped 1.5 percent in production, around 278 million pounds of milk, compared to 2023. It was one of the early potential indicators of the industry’s vulnerability to this virus. However, since then, the nation’s production rebounded to above 2023 numbers. It’s largely why consumers are not seeing the same impact on the price and availability of dairy products like they are with eggs.  “When one state gets H5N1 there are a lot of other states that tend to pick up the slack. So in general, when you look at the national numbers, you really have to squint to kind of find where H5N1 is in the milk production”,” says Loux. California produces around a fifth of the nation’s dairy, and since August over half of the state’s herds had an outbreak. In October, California saw a near four percent drop in milk production compared to 2023, equating to about 127 million pounds of milk. On Thursday, the USDA released November’s data on milk production showing California with the largest decrease this year of 301 million fewer gallons of milk compared to 2023. That is more than double the decrease of last month. Still, the nation only saw a near 1 percent decrease since 2023. How the next administration handles this virus may spell a different story for the dairy industry and the country. With Trump’s history of downplaying infectious diseases and promoting unfounded cures, and public health cabinet nominations who decry vaccine effectiveness, a human-to-human outbreak could lead to another pandemic. Likely to take over the USDA is Brooke Rollins, who, according to Politico, had less experience in agriculture than others on Trump’s shortlist (though she does have a degree in agriculture development). It’s currently unclear what her plans are for handling this virus and supporting farmers and the industry at large. Rollins did not respond to my request for an interview. Should I be worried about getting sick from drinking milk? Drinking pasteurized milk is safe. For more than 100 years, pasteurization has kept the public safe by killing harmful bacteria and viruses. The CDC is warning against raw milk consumption, on the other hand, due to it potentially having high-levels of bird flu. While there’s yet to be a human case of bird flu traced to raw milk consumption, there is fear that the unpasteurized product could lead to illness. And raw milk loaded with the virus has been linked to deaths in other mammals, like cats. Robert F. Kennedy Jr, the likely soon-to-be director of Health and Human Services under Trump, has a history of promoting raw milk. Earlier this month, Kennedy’s favorite raw milk brand was recalled by California after testing positive for bird flu. Kennedy’s rise to public health power comes at time when raw milk is rising in popularity on TikTok. In response to the spread of bird flu in raw milk, the USDA announced a national strategy requiring milk samples nationwide be tested by the agency. Since officially beginning testing on Monday, 16 new bird flu outbreaks in cow herds have been identified in two states. For now, as the nation continues to work on controlling the spread of bird flu, consider tossing your raw milk out before it does more than just spoil.

Blob-headed fish and amphibious mouse among 27 new species found in ‘thrilling’ Peru expedition

Scientists surprised to find so many animals unknown to science in Alto Mayo, a well-populated regionResearchers in the Alto Mayo region of north-west Peru have discovered 27 species that are new to science, including a rare amphibious mouse, a tree-climbing salamander and an unusual “blob-headed fish”. The 38-day survey recorded more than 2,000 species of wildlife and plants.The findings are particularly surprising given the region’s high human population density, with significant pressures including deforestation and agriculture.

Researchers in the Alto Mayo region of north-west Peru have discovered 27 species that are new to science, including a rare amphibious mouse, a tree-climbing salamander and an unusual “blob-headed fish”. The 38-day survey recorded more than 2,000 species of wildlife and plants.The findings are particularly surprising given the region’s high human population density, with significant pressures including deforestation and agriculture.The expedition was “thrilling to be part of”, said Dr Trond Larsen, senior director of biodiversity and ecosystem science at Conservation International’s Moore Centre for Science, who led the survey. “The Alto Mayo landscape supports 280,000 people in cities, towns and communities. With a long history of land-use change and environmental degradation, I was very surprised to find such high overall species richness, including so many new, rare and threatened species, many of which may be found nowhere else.”Researchers have discovered a new species of amphibious mouse, which belongs to a group of semi-aquatic rodents considered to be among the rarest in the world. Photograph: Ronald DiazThe “new” species include four mammals: a spiny mouse, a short-tailed fruit bat, a dwarf squirrel and the semi-aquatic mouse. Discovering a new species of amphibious mouse was “shocking and exciting”, Larsen said. “It belongs to a group of carnivorous, semi-aquatic rodents, for which the majority of species are exceedingly rare and difficult to collect, giving them an almost mythical status among mammal experts … We only found this amphibious mouse in a single unique patch of swamp forest that’s threatened by encroaching agriculture, and it may not live anywhere else.”The dwarf squirrel is about 14cm long and fast-moving, making it extremely difficult to spot in the dense rainforest.Larsen was particularly satisfied to find a new arboreal salamander “with stubby little legs and mottled chestnut-brown colouration, climbing at chest height in a small patch of white sand forest”. But the most intriguing find was “the blob-headed fish, which looks similar to related catfish species but with a truly bizarre speckled blob-like extension on the end of its head”, Larsen said. “The function of this ‘blob’ remains a complete mystery. If I had to speculate, I might guess it could have something to do with sensory organs in the head, or it may assist with buoyancy control, provide fat reserves or aid in its foraging strategy.”A new species of salamander, which spends most of its time in low vegetation and shrubs, was among the discoveries. Photograph: Trond LarsenSeven other new types of fish were also documented, along with a new species of narrow-mouthed frog, 10 new butterflies and two new dung beetles. Another 48 species that were found may also be new to science, with analysis under way to confirm.The expedition also documented 49 “threatened” species from the IUCN’s red list, including two critically endangered monkeys (the Peruvian yellow-tailed woolly monkey and San Martin titi monkey), two endangered birds (the speckle-chested piculet and long-whiskered owlet) and an endangered harlequin frog.The survey was conducted in June and July 2022, using camera traps, bioacoustics sensors and environmental DNA (eDNA) collected from rivers and other water sources. The team of 13 scientists included Peruvian scientists from Global Earth, as well as seven technical assistants with extensive traditional knowledge from Feriaam (the Indigenous Regional Federation of the Alto Mayo Awajún Communities). Of the 2,046 total species recorded, at least 34 appear to live only in the Alto Mayo landscape or the San Martin region it falls in.Members of the insect team survey a swamp forest using nets and various types of traps. Photograph: Trond LarsenWhile the species have never been described by science (the process of assigning a species and name), some were already known to Indigenous communities. “As Awajún people, we have a great deal of knowledge about our territory,” said Yulisa Tuwi, who assisted with the research on reptiles and amphibians. “We know the value of our plants, how they cure us, how they feed us and we know paths within the forest that have led us to meet different animals.“Although we don’t know scientific names, we’ve developed a classification of these species … I believe the discoveries are for the scientific world, not so much for us, as these species are known under other names or for their usefulness or behaviour in nature.”Researchers hope the survey will bolster conservation efforts, including plans to create a network of local protected areas.
