Jane Goodall dies at 91 after transforming chimpanzee science and conservation

British primatologist Jane Goodall, who transformed the study of chimpanzees and became one of the world’s most revered wildlife advocates, has died at the age of 91, her institute announced Wednesday. Goodall “passed away due to natural causes” while in California on a speaking tour of the United States, the Jane Goodall Institute said in a statement on Instagram. In a final video posted before her death, Goodall, dressed in her trademark green, told an audience: “Some of us could say ‘Bonjour,’ some of us could say ‘Guten Morgen,’ and so on, but I can say, ‘Hoo-hoo-hoo-hoo-hoo-hoo-hoo! That’s ‘good morning’ in chimpanzee.'” Tributes poured in from across the conservation world.  “Dr. Jane Goodall was able to share the fruits of her research with everyone, especially the youngest, and to change our view of great apes,” said Audrey Azoulay, director general of UNESCO, adding Goodall had supported the agency’s conservation work. “My heart breaks at the news that the brave, heartful, history-making Jane Goodall has passed,” actress Jane Fonda said on Instagram. “I loved her very much.” “I think the best way we can honor her life is to treat the earth and all its beings like our family, with love and respect,” added Fonda, herself a prominent environmental activist.  Groundbreaking discoveries Born in London on April 3, 1934, Goodall grew fascinated with animals in her early childhood, when her father gave her a stuffed toy chimpanzee that she kept for life. She was also captivated by the Tarzan books, about a boy raised by apes who falls in love with a woman named Jane. In 1957 at the invitation of a friend she traveled to Kenya, where she began working for the renowned paleontologist Louis Leakey. Goodall’s breakthrough came when Leakey dispatched her to study chimpanzees in Tanzania. She became the first of three women he chose to study great apes in the wild, alongside American Dian Fossey (gorillas) and Canadian Birute Galdikas (orangutans). Goodall’s most famous finding was that chimpanzees use grass stalks and twigs as tools to fish termites from their mounds. On the strength of her research, Leakey urged Goodall to pursue a doctorate at Cambridge University, where she became only the eighth person ever to earn a PhD without first obtaining an undergraduate degree. She also documented chimpanzees’ capacity for violence — from infanticide to long-running territorial wars — challenging the notion that our closest cousins were inherently gentler than humans. Instead, she showed they too had a darker side. In 1977 she founded the Jane Goodall Institute to further research and conservation of chimpanzees. In 1991 she launched Roots & Shoots, a youth-led environmental program that today operates in more than 60 countries. Her activism was sparked in the 1980s after attending a US conference on chimpanzees, where she learned of the threats they faced: exploitation in medical research, hunting for bushmeat, and widespread habitat destruction. From then on, she became a relentless advocate for wildlife, traveling the globe into her nineties. Goodall married twice: first to Dutch nobleman and wildlife photographer Baron Hugo van Lawick, with whom she had her only child, Hugo Eric Louis van Lawick, who survives her.  That marriage ended in divorce and was followed by a second, to Tanzanian lawmaker Derek Bryceson, who later died of cancer. Message of hope Goodall wrote dozens of books, including for children. She appeared in documentaries, and earned numerous honors, among them being made a Dame Commander by Britain and receiving the US Presidential Medal of Freedom from then-president Joe Biden. She was also immortalized as both a Lego figure and a Barbie doll, and was famously referenced in a Gary Larson cartoon depicting two chimps grooming. “Conducting a little more ‘research’ with that Jane Goodall tramp?” one chimp asks the other, after finding a blonde hair. Her institute threatened legal action, but Goodall herself waved it off, saying she found it amusing. “The time for words and false promises is past if we want to save the planet,” she told AFP in an interview last year ahead of a UN nature summit in Colombia. Her message was also one of personal responsibility and empowerment. “Each individual has a role to play, and every one of us makes some impact on the planet every single day, and we can choose what sort of impact we make.” The post Jane Goodall dies at 91 after transforming chimpanzee science and conservation appeared first on The Tico Times | Costa Rica News | Travel | Real Estate.

Why Is This Remote and Rugged River in Alaska Turning Orange?

New research suggests the Salmon River is full of toxic metals that are likely harming fish and other aquatic creatures

Why Is This Remote and Rugged River in Alaska Turning Orange? New research suggests the Salmon River is full of toxic metals that are likely harming fish and other aquatic creatures Sarah Kuta - Daily Correspondent October 1, 2025 4:56 p.m. New research suggests that the Salmon River in northwest Alaska is full of toxic metals. Ray Koleser Alaska’s Salmon River was once so clean that author John McPhee described it as the “clearest, purest water I have ever seen flowing over rocks.” Now, however, the remote waterway is a muddy, orangish-yellow mess. It’s brimming with toxic metals, at concentrations that are likely harmful to aquatic life. The culprit? Thawing permafrost resulting from climate change, according to a study published in the journal Proceedings of the National Academy of Sciences last month. “It’s a sobering study,” says Diane McKnight, a geochemist at the University of Colorado Boulder who was not involved with the research, to Chemical & Engineering News’ Fionna Samuels. The Salmon River winds 70 miles through Kobuk Valley National Park in northwest Alaska, flowing from Mount Angayukaqsraq to the Kobuk River. The federal government designated it a National Wild and Scenic River in 1980, noting its large salmon runs and its “water of exceptional clarity.” However, around 2019, the once-crystal-clear waters of the Salmon River and its tributaries turned orange and murky. Patrick Sullivan, an ecologist at the University of Alaska Anchorage, and Roman Dial, a now-retired biologist at Alaska Pacific University, first noticed the unusual hue during an unrelated research trip in the region. Fun Fact Alaska archaeology Alaska is home to the oldest known evidence of salmon fishing in the Americas—11,500-year-old fish bones. The Salmon River had become what’s known as a “rusting river,” a phenomenon caused by the presence of high amounts of iron and other metals. Sullivan, Dial and their colleagues returned to the waterway to take samples in 2022 and 2023. Based on their analyses, they suspect it has fallen victim to sulfide mineral weathering, also known as acid-rock drainage, which can occur when permafrost thaws. Found primarily in the Arctic and some high-elevation regions, permafrost is the name given to soil, sand, sediment and rock that remains at or below freezing temperatures for at least two years. The bedrock beneath some permafrost contains sulfide minerals, which are typically inaccessible to groundwater. However, when permafrost thaws, those minerals become exposed to water and oxygen for the first time in hundreds or even thousands of years. As the minerals dissolve, they produce acids, which in turn cause metals to leach out of rocks. In this way, acid-rock drainage is a form of natural pollution that can occur far from humans—even though it’s caused by human activity. “There are few places left on Earth as untouched as these rivers,” says co-author Tim Lyons, a geochemist at the University of California Riverside, to BBC Wildlife Magazine’s Daniel Graham. “But even here, far from cities and highways, the fingerprint of global warming is unmistakable. No place is spared.” The team’s analyses show the Salmon River is chock-full of metals—including aluminum, cadmium, copper, iron, nickel, and zinc—at concentrations above the U.S. Environmental Protection Agency’s safe limits for aquatic life. “If there were a mine that were operating in the headwaters of the Salmon, they would be facing regulatory intervention at this point,” Sullivan tells Chemical & Engineering News. Pollution from mines is typically limited to a single source and can be managed with treatment systems. Acid-rock drainage caused by permafrost thaw, on the other hand, is occurring at various sites and is nearly impossible to mitigate, the researchers say. “The only hope for solving this problem…is the recovery of the permafrost, which of course would involve pretty massive emissions reductions at this point,” Sullivan tells Chemical & Engineering News. And the ripple effects of permafrost thaw are not limited to the Salmon River. The process can occur in any waterway located near permafrost covering sulfide-rich bedrock, and scientists are using satellite imagery to look for other rivers and streams that might be affected. The high levels of toxic metals in the Salmon River might help explain a recent drop in the number of chum salmon returning to spawn, the researchers say. But, they add, they need to conduct more research to confirm that hunch. Even if the pollution is not to blame for the depressed salmon runs, it’s likely still affecting the local food chain. “It would be very hard, for instance, for a bear to fish for a salmon just because of the turbidity,” Sullivan tells the Alaska Beacon’s Yereth Rosen. “Raptors would have a really hard time catching a fish if they were fishing there.” The water is simply too cloudy, he says, citing his own failed attempts to fish the river. The metals also seem to be harming aquatic insects, such as stoneflies and mayflies, a source of food for many fish, per Science’s Warren Cornwall. In parts of the Salmon River with high levels of aluminum and iron, for instance, the scientists found very few insect larvae. “We have no idea when that process might reach its conclusion and how many new acid seeps might develop,” Sullivan tells the Alaska Beacon.

Jane Goodall, dogged advocate for the natural world, has died aged 91

Acclaimed conservationist and chimpanzee expert Jane Goodall has died, leaving behind a legacy of empathy for primates and the natural world

Jane Goodall studying the behaviour of a chimpanzee during her research in TanzaniaPenelope Breese/Liaison Renowned conservationist Jane Goodall has died at the age of 91. She spent decades studying and advocating for chimpanzees, became the world’s leading expert on our closest primate relatives and transformed our understanding of humankind. She leaves behind a towering legacy of empathy and care for the natural world. According to a 1 October statement from the Jane Goodall Institute, she died of natural causes while in California on a speaking tour. Goodall began studying chimpanzees at Gombe Stream National Park in Tanzania in 1960. She made monumental strides in understanding their behaviours and group dynamics. Over the following 65 years, she became not just an expert but an outspoken advocate, teaching the world about the similarities between humans and other primates and shedding light on the plight chimpanzees and other animals in the wild face from climate change, poaching and habitat destruction. In 1977, she established her eponymous institute, a non-profit with the goal of studying and protecting primates and their habitats while increasing public understanding of the natural world. Over time, the institute’s mission expanded beyond studying primates – for example, by starting community health initiatives across Africa and even forming a committee dedicated to protecting whales. Goodall was also a founder or board member for countless other environmental protection initiatives. She cited extraordinary patience as key to her achievements. “There were moments when I was depressed, and the chimps were running away, and I was a long time in the field. I thought: oh bother, drat. [But] if I’d given up, I would never have forgiven myself. I could never live with myself,” she told New Scientist in 2022. Later in her life, Goodall spent most of her energy on conservation activism, travelling the world to get out the message that animals – all of them, not just chimpanzees – and humanity aren’t so different after all. She never stopped pushing for us to treat the natural world better. 

Concrete “battery” developed at MIT now packs 10 times the power

Improved carbon-cement supercapacitors could turn the concrete around us into massive energy storage systems.

Concrete already builds our world, and now it’s one step closer to powering it, too. Made by combining cement, water, ultra-fine carbon black (with nanoscale particles), and electrolytes, electron-conducting carbon concrete (ec3, pronounced “e-c-cubed”) creates a conductive “nanonetwork” inside concrete that could enable everyday structures like walls, sidewalks, and bridges to store and release electrical energy. In other words, the concrete around us could one day double as giant “batteries.”As MIT researchers report in a new PNAS paper, optimized electrolytes and manufacturing processes have increased the energy storage capacity of the latest ec3 supercapacitors by an order of magnitude. In 2023, storing enough energy to meet the daily needs of the average home would have required about 45 cubic meters of ec3, roughly the amount of concrete used in a typical basement. Now, with the improved electrolyte, that same task can be achieved with about 5 cubic meters, the volume of a typical basement wall.“A key to the sustainability of concrete is the development of ‘multifunctional concrete,’ which integrates functionalities like this energy storage, self-healing, and carbon sequestration. Concrete is already the world’s most-used construction material, so why not take advantage of that scale to create other benefits?” asks Admir Masic, lead author of the new study, MIT Electron-Conducting Carbon-Cement-Based Materials Hub (EC³ Hub) co-director, and associate professor of civil and environmental engineering (CEE) at MIT.The improved energy density was made possible by a deeper understanding of how the nanocarbon black network inside ec3 functions and interacts with electrolytes. Using focused ion beams for the sequential removal of thin layers of the ec3 material, followed by high-resolution imaging of each slice with a scanning electron microscope (a technique called FIB-SEM tomography), the team across the EC³ Hub and MIT Concrete Sustainability Hub was able to reconstruct the conductive nanonetwork at the highest resolution yet. This approach allowed the team to discover that the network is essentially a fractal-like “web” that surrounds ec3 pores, which is what allows the electrolyte to infiltrate and for current to flow through the system. “Understanding how these materials ‘assemble’ themselves at the nanoscale is key to achieving these new functionalities,” adds Masic.Equipped with their new understanding of the nanonetwork, the team experimented with different electrolytes and their concentrations to see how they impacted energy storage density. As Damian Stefaniuk, first author and EC³ Hub research scientist, highlights, “we found that there is a wide range of electrolytes that could be viable candidates for ec3. This even includes seawater, which could make this a good material for use in coastal and marine applications, perhaps as support structures for offshore wind farms.”At the same time, the team streamlined the way they added electrolytes to the mix. Rather than curing ec3 electrodes and then soaking them in electrolyte, they added the electrolyte directly into the mixing water. Since electrolyte penetration was no longer a limitation, the team could cast thicker electrodes that stored more energy.The team achieved the greatest performance when they switched to organic electrolytes, especially those that combined quaternary ammonium salts — found in everyday products like disinfectants — with acetonitrile, a clear, conductive liquid often used in industry. A cubic meter of this version of ec3 — about the size of a refrigerator — can store over 2 kilowatt-hours of energy. That’s about enough to power an actual refrigerator for a day.While batteries maintain a higher energy density, ec3 can in principle be incorporated directly into a wide range of architectural elements — from slabs and walls to domes and vaults — and last as long as the structure itself.“The Ancient Romans made great advances in concrete construction. Massive structures like the Pantheon stand to this day without reinforcement. If we keep up their spirit of combining material science with architectural vision, we could be at the brink of a new architectural revolution with multifunctional concretes like ec3,” proposes Masic.Taking inspiration from Roman architecture, the team built a miniature ec3 arch to show how structural form and energy storage can work together. Operating at 9 volts, the arch supported its own weight and additional load while powering an LED light.However, something unique happened when the load on the arch increased: the light flickered. This is likely due to the way stress impacts electrical contacts or the distribution of charges. “There may be a kind of self-monitoring capacity here. If we think of an ec3 arch at architectural scale, its output may fluctuate when it’s impacted by a stressor like high winds. We may be able to use this as a signal of when and to what extent a structure is stressed, or monitor its overall health in real time,” envisions Masic.The latest developments in ec³ technology bring it a step closer to real-world scalability. It’s already been used to heat sidewalk slabs in Sapporo, Japan, due to its thermally conductive properties, representing a potential alternative to salting. “With these higher energy densities and demonstrated value across a broader application space, we now have a powerful and flexible tool that can help us address a wide range of persistent energy challenges,” explains Stefaniuk. “One of our biggest motivations was to help enable the renewable energy transition. Solar power, for example, has come a long way in terms of efficiency. However, it can only generate power when there’s enough sunlight. So, the question becomes: How do you meet your energy needs at night, or on cloudy days?”Franz-Josef Ulm, EC³ Hub co-director and CEE professor, continues the thread: “The answer is that you need a way to store and release energy. This has usually meant a battery, which often relies on scarce or harmful materials. We believe that ec3 is a viable substitute, letting our buildings and infrastructure meet our energy storage needs.” The team is working toward applications like parking spaces and roads that could charge electric vehicles, as well as homes that can operate fully off the grid.“What excites us most is that we’ve taken a material as ancient as concrete and shown that it can do something entirely new,” says James Weaver, a co-author on the paper who is an associate professor of design technology and materials science and engineering at Cornell University, as well as a former EC³ Hub researcher. “By combining modern nanoscience with an ancient building block of civilization, we’re opening a door to infrastructure that doesn’t just support our lives, it powers them.”

Evolution may explain why women live longer than men

In most mammals, females live longer than males, but in birds the trend goes the other way – a study of over 1000 species points to possible reasons for these differences

Women live longer than men on average in every countryPeter Cavanagh/Alamy We now have a better idea of why women live longer than men, on average, thanks to the most comprehensive analysis yet of the differences in lifespan between male and female mammals and birds. The average global life expectancy is about 74 years for women and 68 years for men. There are various ideas to explain why women tend to live longer than men, including the suggestion that young men are more likely to die in accidents or conflicts, and that women are better protected against potentially harmful mutations in the sex-determining chromosomes than men, but the picture is far from complete. To search for clues from other animals, Johanna Stärk at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and her colleagues analysed data on life expectancy in 1176 species – 528 mammals and 648 birds – in zoos as well as in wild populations. They found that in 72 per cent of the mammal species, females live longer than males, by 12 or 13 per cent on average. But in birds, males tend to outlive females in 68 per cent of the species, surviving about 5 per cent longer on average. The researchers say this trend backs up the idea that sex chromosomes account for some of the differences in lifespan. In mammals, having two copies of the X chromosome makes an individual genetically female, while males have two different sex chromosomes, an X and a Y. In theory, females are better protected against harmful mutations in the sex chromosomes, because the second copy of the X chromosome acts as a backup. In birds, the sex determination system is the other way around: females have two different sex chromosomes, called Z and W, while males have two Z chromosomes. So the different life expectancy trends in mammals and birds back up the idea that the sex with different chromosomes – the heterogametic sex – incurs a longevity cost. “But what was very interesting is that we found exceptions,” says team member Fernando Colchero, also at the Max Planck Institute for Evolutionary Anthropology. “And with those exceptions, our idea was to test other evolutionary hypotheses for why these sex differences occur.” Digging deeper into the data, the team found that mating systems seem to play a role. In polygamous mammals where there is strong competition for mates – such as baboons, gorillas and chimpanzees – males generally die earlier than females. “Due to competition for mating opportunities, individuals – typically the males – will invest into traits favoured by sexual selection, such as large body size, ornamental feathers or antlers,” says Nicole Riddle at the University of Alabama at Birmingham. “These traits are costly to produce, and there are typically other costs associated with the competition for mating opportunities, for example through fights with other males.” These factors will mean that the individual has less resources available to invest in its own long-term survival, she says. Males that invest in costly traits to win mates may have shorter lifespans as a resultRebius/Shutterstock This is also true of birds with polygamous mating systems. “Overall, this may also explain why the male advantage in birds is considerably lower than the female advantage in mammals,” says Pau Carazo at the University of Valencia in Spain. He says that in mammals, both the genetic factor and sexual selection traits work in the same direction in shortening male lifespan, whereas in birds the pressures may balance each other out, because males are often involved in strong sexual selection, but females bear the costs of heterogamy. Stärk and her colleagues also found that the sex that invests more in raising offspring tends to live longer. In mammals, this is often the females. In long-lived species like humans or other primates, this is probably evolutionarily advantageous, because it helps females survive until their offspring are sexually mature themselves. However, there were exceptions. “Birds of prey are the opposite of everything that we’re finding in the other species,” says Stärk. “The females are larger, and it’s often the females that engage much more in protection of the territory, but still females live longer.” Why is a mystery, she says. The lifespan differences between sexes are smaller in zoo populations than in wild populations, says Carazo, probably because life in captivity minimises environmental pressures like fights, predation and disease. This control over the environment might also be why lifespan differences between the sexes in humans have been shrinking, he says, although they might never go away entirely. “There are still some very strongly coded differences – physiological differences and genetic differences – between men and women,” says Colchero. “Who knows where medical sciences are going to take us, but in general, we don’t expect that those differences are completely going to disappear.”

Wildlife Advocate and Primate Expert Jane Goodall Dies at 91

(Reuters) -Scientist and global activist Jane Goodall, who turned her childhood love of primates into a lifelong quest for protecting the environment, died on Wednesday at the age of 91, the institute she founded said.Goodall died of natural causes, the Jane Goodall Institute said in a social media post."Dr. Goodall’s discoveries as an ethologist revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world," it said.The primatologist-turned-conservationist spun her love of wildlife into a life-long campaign that took her from a seaside English village to Africa and then across the globe in a quest to better understand chimpanzees, as well as the role that humans play in safeguarding their habitat and the planet's health overall.Goodall was a pioneer in her field, both as a female scientist in the 1960s and for her work studying the behavior of primates. She created a path for a string of other women to follow suit, including the late Dian Fossey.She also drew the public into the wild, partnering with the National Geographic Society to bring her beloved chimps into their lives through film, TV and magazines.She upended scientific norms of the time, giving chimpanzees names instead of numbers, observing their distinct personalities, and incorporating their family relationships and emotions into her work. She also found that, like humans, they use tools."We have found that after all there isn't a sharp line dividing humans from the rest of the animal kingdom," she said in a 2002 TED Talk.As her career evolved, she shifted her focus from primatology to climate advocacy after witnessing widespread habitat devastation, urging the world to take quick and urgent action on climate change."We're forgetting that were part of the natural world," she told CNN in 2020. "There's still a window of time."In 2003, she was appointed a Dame of the British Empire and, in 2025, she received the U.S. Presidential Medal of Freedom.Born in London in 1934 and then growing up in Bournemouth on England's south coast, Goodall had long dreamed of living among wild animals. She said her passion for animals, stoked by the gift of a stuffed toy gorilla from her father, grew as she immersed herself in books such as "Tarzan" and "Dr. Dolittle."She set her dreams aside after leaving school, unable to afford university. She worked as a secretary and then for a film company until a friend's invitation to visit Kenya put the jungle - and its inhabitants - within reach.After saving up money for the journey, by boat, Goodall arrived in the East African nation in 1957. There, an encounter with famed anthropologist and paleontologist Dr. Louis Leakey and his wife, archaeologist Mary Leakey, set her on course to work with primates.Under Leakey, Goodall set up the Gombe Stream Chimpanzee Reserve, later renamed the Gombe Stream Research Centre, near Lake Tanganyika in present-day Tanzania. There she discovered chimpanzees ate meat, fought fierce wars, and perhaps most importantly, fashioned tools in order to eat termites."Now we must redefine tool, redefine man, or accept chimpanzees as humans," Leakey said of the discovery.Although she eventually paused her research to earn a PhD at Cambridge University, Goodall remained in the jungle for years. Her first husband and frequent collaborator was wildlife cameraman Hugo van Lawick.Through the National Geographic's coverage, the chimpanzees at Gombe Stream soon became household names - most famously, one Goodall called David Greybeard for his silver streak of hair.Nearly thirty years after first arriving in Africa, however, Goodall said she realized she could not support or protect the chimpanzees without addressing the dire disappearance of their habitat. She said she realized she would have to look beyond Gombe, leave the jungle, and take up a larger global role as a conservationist.In 1977, she set up the Jane Goodall Institute, a nonprofit organization aimed at supporting the research in Gombe as well as conservation and development efforts across Africa. Its work has since expanded worldwide and includes efforts to tackle environmental education, health and advocacy.She made a new name for herself, traveling an average of 300 days a year to meet with local officials in countries around the world and speaking with community and school groups. She continued her world tours into her 90s.She later expanded the institute to include Roots & Shoots, a conservation program aimed at children.It was a stark shift from her isolated research, spending long days watching chimpanzees."It never ceases to amaze me that there's this person who travels around and does all these things," she told the New York Times during a 2014 trip to Burundi and back to Gombe. "And it's me. It doesn't seem like me at all."A prolific author, she published more than 30 books with her observations, including her 1999 bestseller "Reason For Hope: A Spiritual Journey," as well as a dozen aimed at children.Goodall said she never doubted the planet's resilience or human ability to overcome environmental challenges."Yes, there is hope ... It's in our hands, it's in your hands and my hands and those of our children. It's really up to us," she said in 2002, urging people to "leave the lightest possible ecological footprints."She had one son, known as 'Grub,' with van Lawick, whom she divorced in 1974. Van Lawick died in 2002.In 1975, she married Derek Bryceson. He died in 1980.(Writing by Susan Heavey, Editing by Rosalba O'Brien)Copyright 2025 Thomson Reuters.Photos You Should See – Sept. 2025

Jane Goodall, Legendary Primatologist and Anthropologist, Dies at 91

She was considered the world’s leading expert on chimpanzees and was renowned for her global conservation efforts

Jane Goodall, Legendary Primatologist and Anthropologist, Dies at 91 She was considered the world’s leading expert on chimpanzees and was renowned for her global conservation efforts Jane Goodall visiting a chimpanzee rescue center in 2018 in Entebbe, Uganda SUMY SADURNI / AFP via Getty Images Jane Goodall was just 26 years old when she first stepped foot onto the pebbly shore of what’s now Gombe Stream National Park in July of 1960. Though she lacked any formal scientific training, she nonetheless was about to embark on a rare six-month-long field study to observe the elusive chimpanzees living in the Tanzanian forest. Though researchers knew at the time that humans and chimps were closely related, they knew next to nothing about the behavior of the apes in the wild. For three months, Goodall traipsed through the forest, avoided predators and navigated across difficult terrain without making any meaningful observations. Dense leaf growth prevented her from seeing the animals at a distance, and when she attempted to approach the chimps for a closer view, they fled from her. But Goodall was patient, and she eventually managed to gain the trust of a high-ranking male chimp with silver facial hair who she named David Greybeard. Finally, in November the same year, she made an astonishing observation: David Greybeard had bent a twig, stripped off its leaves and used it to “fish” termites from a nest. The ability to use and make tools was previously thought to be what set humans apart from other animals. When she told her mentor, famed archaeologist Louis Leakey, what she saw, he responded: “Now we must redefine tool, redefine man or accept chimpanzees as human.” “She was a pioneer,” says Craig Stanford, an anthropologist and biologist at the University of Southern California and the co-director of the USC Jane Goodall Research Center. “At a time when people thought a long study was six weeks, she went out and spent months and then years, really being immersed in the community of chimps, seeing it from the inside. Nobody had really thought about that before.” Primatologist, conservationist and naturalist Jane Goodall has died at age 91 of natural causes, as her namesake nonprofit, the Jane Goodall Institute, announced in a social media statement on Wednesday. She had been in California as part of an ongoing speaking tour in the United States. “Goodall’s discoveries as an ethologist revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world,” reads the statement. Goodall holds a baby monkey while visiting Chile. HECTOR RETAMAL / AFP via Getty Images Goodall was considered the world’s leading expert on chimpanzees and was renowned for her global conservation efforts. Her decades-long work documenting chimp behavior in Tanzania’s Gombe Stream National Park fundamentally changed our understanding of primates. Not only did she discover that chimps make tools, but her research into the social lives of these primates challenged long-held beliefs that humans are the only species to wage war, manipulate objects and have sophisticated emotions. Goodall also helped re-center conservation efforts around meeting both the needs of local communities and the environment in an approach called “TACARE,” an acronym for Lake Tanganyika Catchment Reforestation and Education. The Jane Goodall Institute has put 3.4 million acres of habitat under conservation action plans and has worked with 130 communities living in or near chimpanzee habitat. As one of the most well-known naturalists in the world and one of the first women to rise to the top in the field of primatology, Goodall inspired generations of young women to pursue careers in science. She spearheaded programs in Uganda and Tanzania to help girls stay in school by offering scholarships, providing them with the training and materials to make reusable sanitary pads and creating a peer support network. Goodall was born in 1934 in London. Ever since she was a child, she recalled having a fascination and love for animals. She would spend hours watching squirrels, birds and insects in the garden of her house. Once, when she was about 4, she disappeared to a henhouse for hours to figure out how the birds laid their eggs, unaware that her family had reported her missing to the police. Her reading list was filled with books like Doctor Dolittle and Tarzan of the Apes. (Later in life, she often joked that Tarzan had married the wrong Jane.) After first reading about Tarzan’s adventures in the jungle, a then 10-year-old Goodall dreamed of traveling to Africa to live and work among wild animals. “Everybody laughed at me,” she said in an interview. “Girls didn’t do that sort of thing back then, but my mother always said if you really want something then you’re going to have to work really hard, take advantage of opportunity and never give up.” Her opportunity came about five years after she graduated from high school. Goodall attended secretarial school, working several jobs to save up money. By 1957, she had earned enough to buy her boat passage to Kenya, where she visited a school friend on her family’s farm. During that trip, she arranged to meet with archaeologist Louis Leakey in Nairobi. Leakey’s secretary had quit two days prior to their meeting, and he promptly hired Goodall as a replacement, she wrote in The Book of Hope. Around that time, the archaeologist, who had gained fame for his human origins research, was looking for someone to undertake an extended observation of great apes in Gombe, thinking the animals could be a window into the lives of early humans. Goodall’s patience and desire to understand animals convinced Leakey she was the right fit for the job. Though she lacked formal scientific training, Leakey believed this would help her make unbiased observations. “He told me that the chimpanzee habitat was remote and rugged and that there would be dangerous animals—and that the chimpanzees themselves were four times stronger than humans,” Goodall said. “Oh, how I longed to undertake an adventure like the one Leakey was envisioning.” So, in 1960, Goodall set out to the forest of Tanzania—a highly unorthodox venture for a young woman at the time. Authorities had insisted she have a companion with her, so her mother, 54-year-old Margaret (“Vanne”), went along. The two shared a single tent furnished with cots, a table and chairs. Goodall broke decades of scientific research precedent by naming the chimpanzees instead of using numbers to identify them—a highly controversial practice that irritated conventional academics. When she suggested that chimpanzees have distinct personalities, she was criticized for anthropomorphizing them. Goodall’s study of the chimps in Gombe extended more than 60 years and led to multiple discoveries, including that chimps are omnivorous, exhibit human-like compassion and have deep mother-infant bonds. “Because she was in Gombe for so long, we learned about generations of chimps,” says Mary Lee Jensvold, a primate communication scientist at Central Washington University. “We learned about things that you could only discover by being there for a long time, like warfare between neighboring communities.” In 1961, Goodall was one of only a few students to enter into a Cambridge University PhD program without first earning her bachelor’s degree. After graduating, she continued her work in Tanzania and helped establish the Gombe Stream Research Center. Goodall’s career pivoted from research, following the “Understanding Chimpanzees” conference she helped organize in Chicago in 1986. The sessions she attended left her in shock—while she had heard of the effects of deforestation and the inhumane conditions chimps faced in medical research labs, she “had no idea the extent of it,” she said to Living on Earth’s Steve Curwood in 2020. “I went as a scientist,” she said. “I left as an activist.” Goodall left behind her research at Gombe and began traveling the world to build conservation programs, give lectures and promote environmentalism. “She had this epiphany that the research was great, fascinating, but ultimately didn’t matter if the animals go extinct,” says Stanford. “So then from that point on…she was on this global mission to save those animals.” Stanford met Goodall back in the 1980s, after he sent her a letter proposing a project to study chimps and the animals they eat. Goodall liked his idea, and he went to Tanzania to complete the research. In the 1990s, he spent six years working part-time in Tanzania and living with Goodall until he built his own house on the shore of Lake Tanganyika. Most of the time when she came to Gombe, Stanford remembers Goodall was often out with CNN, “60 Minutes” or other film crews that were following her life. But in the brief moments he’d spend working alone with her in the forest, Stanford remarked that he was always struck by how she quickly picked up on chimpanzee behaviors he’d never noticed, even in a year of watching them. “Jane was just a brilliant observer,” he says. “That’s something that is critical for anybody who's a primatologist.” Goodall was an incredible champion who was relentless in the work she did, says Jensvold, who’s also the associate director of the Fauna Foundation. The Fauna Foundation cares for former biomedical research chimps, including some that came from the Laboratory for Experimental Medicine and Surgery in Primates (LEMSIP) in New York after it was shut down in 1997. Jensvold recalls when Goodall visited LEMSIP in the 1980s and saw the conditions in which the chimps were kept. Goodall told the lab the chimps needed enrichment activities—a new concept at the time—and helped send one of Jensvold’s graduate student classmates to the lab to teach technicians enrichment techniques. Goodall’s involvement often led to action. “Because she was so influential,” Jensvold says. “She wasn’t afraid to talk about what was going on in labs, and that this is making them crazy.” While the conference in 1986 led Goodall to move from research into full-time activism, the famed primatologist had already founded the Jane Goodall Institute in 1977 to continue her chimpanzee research and work toward chimp protection, conservation and environmental education. Her work focused heavily on centering local communities in conservation and helping with access to food, health care and education. “As outsiders, it’s very easy to say ‘oh, don’t eat bush meat, or ‘don’t do this, and don’t do that,’ until you really see the lives and daily struggles of these people,” says Melissa Hawkins, the curator of mammals at the Smithsonian’s National Museum of Natural History. “I think it’s really amazing the work that she’s done to kind of fill that void and show the rest of the world, for decades now, how important it is to not just blame the people but figure out ways to help.” Goodall created an initiative through the institute in 1991 called Roots and Shoots, which empowers youth to make positive changes for the environment and surrounding communities. Her work in conservation and human rights led the U.N. Secretary-General to name her a U.N. Messenger of Peace in 2002. In 2004, she became a Dame Commander of the British Empire. Throughout her illustrious career, she received numerous other awards and honors, including the Kyoto Prize, the French Legion of Honour and the Medal of Tanzania.

He was sitting with her at a sidewalk café when a middle-aged woman spotted Goodall, stopped abruptly and started to cry. This wasn’t the only time Stanford had witnessed such a response to her presence. “When you see other people’s reaction, it’s so viscerally, deeply emotional, it really tells you—it reminds you—what she means to so many people,” he says. “She’s not just a celebrity. She’s not just an environmentalist. She’s not just a pioneering scientist. She’s this cultural touchstone who represents something pure and good that she devoted her life to.” Though shy and soft-spoken, Goodall always spoke out about climate change and humans’ unhealthy relationship with the planet. She used her own story to inspire people to act on the environment. Goodall often talked at length about her own spirituality, which she said grew while spending time out in the forest and feeling the divine energy and interconnectedness of all living things. This spiritual power guided Goodall on her mission to spread hope and peace throughout the world, she said. Some years ago, during a lecture, Goodall was asked what her next great adventure would be. Then in her 80s, Goodall thought for a second before replying: “dying.” The crowd went silent, then a few people “tittered nervously,” she said in 2022. But Goodall continued: “When you die, there’s either nothing, which is fine, or there’s something, which I happen to believe,” she said. “And if there is something beyond our death, then I cannot think of a greater adventure than finding out what that something is.” Get the latest Science stories in your inbox.

Jane Goodall, legendary researcher and advocate for the planet, dies at 91

Jane Goodall, the conservationist renowned for her groundbreaking chimpanzee field research, has died.

Jane Goodall, the conservationist renowned for her groundbreaking chimpanzee field research and globe-spanning environmental advocacy, has died. She was 91.The Jane Goodall Institute said in post on Instagram Wednesday that the renowned primatologist has died.While living among chimpanzees in Africa decades ago, Goodall documented the animals using tools and doing other activities previously believed to be exclusive to people, and also noted their distinct personalities. Her observations and subsequent magazine and documentary appearances in the 1960s transformed how the world perceived not only humans’ closest living biological relatives but also the emotional and social complexity of all animals, while propelling her into the public consciousness.“Out there in nature by myself, when you’re alone, you can become part of nature and your humanity doesn’t get in the way,” she told The Associated Press in 2021. “It’s almost like an out-of-body experience when suddenly you hear different sounds and you smell different smells and you’re actually part of this amazing tapestry of life.”In her later years, Goodall devoted decades to education and advocacy on humanitarian causes and protecting the natural world. In her usual soft-spoken British accent, she was known for balancing the grim realities of the climate crisis with a sincere message of hope for the future.From her base in the coastal U.K. town of Bournemouth, she traveled nearly 300 days a year well into her 90’s to speak to packed auditoriums around the world. Between more serious messages, her speeches often featured her whooping like a chimpanzee or lamenting that Tarzan chose the wrong Jane.FILE - Jane Goodall plays with Bahati, a 3-year-old female chimpanzee, at the Sweetwaters Chimpanzee Sanctuary near Nanyuki, north of Nairobi, on Dec. 6, 1997.AP Photo/Jean-Marc Bouju, FileWhile first studying chimps in Tanzania in the early 1960s, Goodall was known for her unconventional approach. She didn’t simply observe them from afar but immersed herself in every aspect of their lives. She fed them and gave them names instead of numbers, something for which she received pushback from some scientists.Her findings were circulated to millions when she first appeared on the cover of National Geographic in 1963 and soon after in a popular documentary. A collection of photos of Goodall in the field helped her and even some of the chimps become famous. One iconic image showed her crouching across from the infant chimpanzee named Flint. Each has arms outstretched, reaching for the other.In 1972, the Sunday Times published an obituary for Flo, Flint’s mother and the dominant matriarch, after she was found face down on the edge of a stream. Flint died about three weeks later after showing signs of grief, eating little and losing weight.″What the chimps have taught me over the years is they’re so like us. They’ve blurred the line between humans and animals,″ she told The Associated Press in 1997.Goodall has earned top civilian honors from a number of countries including Britain, France, Japan and Tanzania. She was awarded the Presidential Medal of Freedom in 2025 by then-U.S. President Joe Biden and won the prestigious Templeton Prize in 2021.FILE - President Joe Biden, right, presents the Presidential Medal of Freedom, the Nation's highest civilian honor, to conservationist Jane Goodall in the East Room of the White House, Jan. 4, 2025, in Washington.AP Photo/Manuel Balce Ceneta, File“Her groundbreaking discoveries have changed humanity’s understanding of its role in an interconnected world, and her advocacy has pointed to a greater purpose for our species in caring for life on this planet,” said the citation for the Templeton Prize, which honors individuals whose life’s work embodies a fusion of science and spirituality.Goodall was also named a United Nations Messenger of Peace and published numerous books, including the bestselling autobiography “Reason for Hope.”Born in London in 1934, Goodall said her fascination with animals began around when she learned to crawl. In her book, “In the Shadow of Man,” she described an early memory of hiding in a henhouse to see a chicken lay an egg. She was in there so long her mother reported her missing to the police.She bought her first book — Edgar Rice Burroughs’ “Tarzan of the Apes” — when she was 10 and soon made up her mind about her future: Live with wild animals in Africa.That plan stayed with her through a secretarial course when she was 18 and two different jobs. And by 1957, she accepted an invitation to travel to a farm in Kenya owned by a friend’s parents.It was there that she met the famed anthropologist and paleontologist Louis Leakey at a natural history museum in Nairobi, and he gave her a job as an assistant secretary.Three years later, despite Goodall not having a college degree, Leakey asked if she would be interested in studying chimpanzees in what is now Tanzania. She told the AP in 1997 that he chose her “because he wanted an open mind.”The beginning was filled with complications. British authorities insisted she have a companion, so she brought her mother at first. The chimps fled if she got within 500 yards of them. She also spent weeks sick from what she believes was malaria, without any drugs to combat it.But she was eventually able to gain the animals’ trust. By the fall of 1960 she observed the chimpanzee named David Greybeard make a tool from twigs and use it to fish termites from a nest. It was previously believed that only humans made and used tools.She also found that chimps have individual personalities and share humans’ emotions of pleasure, joy, sadness and fear. She documented bonds between mothers and infants, sibling rivalry and male dominance. In other words, she found that there was no sharp line between humans and the animal kingdom.In later years, she discovered chimpanzees engage in a type of warfare, and in 1987 she and her staff observed a chimp “adopt” a 3-year-old orphan that wasn’t closely related.Goodall received dozens of grants from the National Geographic Society during her field research tenure, starting in 1961.In 1966, she earned a Ph.D. in ethology — becoming one of the few people admitted to University of Cambridge as a Ph.D. candidate without a college degree.Her work moved into more global advocacy after she watched a disturbing film of experiments on laboratory animals at a conference in 1986.″I knew I had to do something,″ she told the AP in 1997. ″It was payback time.″When the COVID-19 pandemic hit in 2020 and halted her in-person events, she began podcasting from her childhood home in England. Through dozens of “Jane Goodall Hopecast” episodes, she broadcast her discussions with guests including U.S. Sen. Cory Booker, author Margaret Atwood and marine biologist Ayana Elizabeth Johnson.“If one wants to reach people; If one wants to change attitudes, you have to reach the heart,” she said during her first episode. ”You can reach the heart by telling stories, not by arguing with people’s intellects.”In later years, she pushed back on more aggressive tactics by climate activists, saying they could backfire, and criticized “gloom and doom” messaging for causing young people to lose hope.In the lead-up to 2024 elections, she co-founded “Vote for Nature,” an initiative encouraging people to pick candidates committed to protecting the natural world.She also built a strong social media presence, posting to millions of followers about the need to end factory farming or offering tips on avoiding being paralyzed by the climate crisis.Her advice: “Focus on the present and make choices today whose impact will build over time.”--By Hallie Golden/The Associated PressIf you purchase a product or register for an account through a link on our site, we may receive compensation.

Nearly 90 percent of EPA furloughed as government shuts down

About 89 percent of the Environmental Protection Agency’s (EPA’s) workforce is being furloughed as the government shuts down, according to contingency plans that were posted online this week.

About 89 percent of the Environmental Protection Agency’s (EPA’s) workforce is being furloughed as the government shuts down, according to contingency plans that were posted online this week. According to the plan, just 1,734 of the EPA’s 15,166 employees are slated to continue working during the shutdown, which began Wednesday. The plan also gives a window into the degree of staffing losses at the EPA in recent months, as the agency had 17,080 employees at the start of the year.  During the furlough period, the agency will no longer carry out most civil inspections related to potential violations of environmental law.  It will also no longer conduct most of its research or issue new permits or grants. Some hazardous waste cleanup will be halted if there is no imminent threat to human health and property. The EPA will still continue emergency and disaster assistance, hazardous waste cleanup where there is an “imminent threat to human life" and criminal investigations. The Trump administration’s plan is similar to the most recent contingency plan issued by the Biden administration in September 2024. Under that plan, 1,734 employees out of 16,851 would have been expected to continue working. Under the Biden-era plan, civil inspections, issuance of new grants and permits, research and some hazardous waste cleanup also would have ceased. Marc Boom, a former EPA senior policy adviser during the Biden administration, said during a press call ahead of the shutdown that if one occurs “nobody will be holding polluters accountable for what they dump into the air we breathe and the water that we drink.” But Boom also said the Trump administration is making the problem worse. “Over the past 9 months, the White House and EPA leadership have already been shutting down the agency from within,” he said. “They've clawed back hundreds of community grants, rolled back protections against forever chemicals and pesticides, relaxed enforcement for polluters … and they've shuttered key programs like the Environmental Justice Office, the Office of Atmospheric Protection and now, they're closing down EPA's scientific backbone, the Office of Research and Development.” The EPA has said that its actions are in support of a deregulatory agenda that seeks to boost the U.S. economy.
