Credit: Expedition Cyclops An international team rediscovered the rare Attenborough’s long-beaked echidna in Indonesia, also uncovering new species and a cave system. These findings, achieved with local community collaboration, contribute significantly to biodiversity and geological research. A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp. Rediscovery of Attenborough’s Long-Beaked Echidna More than sixty years after it was last recorded, an expedition team has rediscovered an iconic, egg-laying mammal in one of the most unexplored regions of the world. Attenborough’s long-beaked echidna, named after famed broadcaster Sir David Attenborough, was captured for the first time in photos and video footage using remote trail cameras set up in the Cyclops Mountains of Indonesia’s Papua Province. Diverse Discoveries Amidst Challenges Alongside the echidna’s rediscovery, the expedition – a partnership between the University of Oxford, Indonesian NGO Yayasan Pelayanan Papua Nenda (YAPPENDA), Cenderawasih University (UNCEN), Papua BBKSDA, and the National Research and Innovation Agency of Indonesia (BRIN), Re:Wild – made many other remarkable finds. These included Mayr’s honeyeater, a bird lost to science since 2008; an entirely new genus of tree-dwelling shrimp; countless new species of insects; and a previously unknown cave system. This was despite the difficulties posed by extremely inhospitable terrain, including venomous animals, blood-sucking leeches, malaria, earthquakes, and exhausting heat. Attenborough’s long-beaked echidna, filmed using a camera trap. Credit: Expedition Cyclops One of the World’s Most Unusual Mammals Finally Caught On Film Recorded by science only once in 1961, Attenborough’s long-beaked echidna is a monotreme: an evolutionarily distinct group of egg-laying mammals that includes the platypus. This echidna species is so special because it is one of only five remaining species of monotremes, the sole guardians of this remarkable branch of the tree of life. Echidnas are notoriously difficult to find since they are nocturnal, live in burrows, and tend to be very shy. Attenborough’s long-beaked echidna has never been recorded anywhere outside the Cyclops Mountains, and is currently classified as Critically Endangered on the IUCN Red List of Threatened Species A temporary expedition campsite on the northern slopes of the Cyclops Mountains. Members of the Yongsu Sapari community helped prepare paths and campsites for the expedition to conduct their research. Credit: Expedition Cyclops To give themselves the best chance of finding one, the team deployed over 80 trail cameras, making multiple ascents of the mountains, and climbing more than 11,000 meters (more than the height of Everest) in the process. For almost the entire four weeks that the team spent in the forest, the cameras recorded no sign of the echidna. On the last day, with the last images on the final memory card, the team obtained their shots of the elusive mammal – the first-ever photographs of Attenborough’s echidna. The identification of the species was later confirmed by Professor Kristofer Helgen, mammalogist and chief scientist and director of the Australian Museum Research Institute (AMRI). The Echidna’s Distinctive Features Dr. James Kempton, a biologist from the University of Oxford who conceived of and led the expedition, said: “Attenborough’s long-beaked echidna has the spines of a hedgehog, the snout of an anteater, and the feet of a mole. Because of its hybrid appearance, it shares its name with a creature of Greek mythology that is half human, half serpent. The reason it appears so unlike other mammals is because it is a member of the monotremes – an egg-laying group that separated from the rest of the mammal tree-of-life about 200 million years ago.” Expedition leader Dr. James Kempton (University of Oxford) collecting specimens after ascending the slopes of the Cyclops Mountains. Credit: Expedition Cyclops “The discovery is the result of a lot of hard work and over three and a half years of planning,” he added. “A key reason why we succeeded is because, with the help of YAPPENDA, we have spent years building a relationship with the community of Yongsu Sapari, a village on the north coast of the Cyclops Mountains. The trust between us was the bedrock of our success because they shared with us the knowledge to navigate these treacherous mountains, and even allowed us to research on lands that have never before felt the tread of human feet.” About Attenborough’s long-beaked echidna: Attenborough’s long-beaked echidna, Zaglossus attenboroughi, is not known to live outside the Cyclops Mountains and biologists still have many unanswered questions about its habitat and ecology. Attenborough’s long-beaked echidna is an EDGE species: a threatened species that has few close relatives on the evolutionary tree of life. They have evolved independently of other mammals for about 200 million years. The echidna has cultural significance for the people of Yongsu Sapari, who have lived on the northern slopes of the Cyclops Mountains for eighteen generations. When there is a conflict within the community, rather than fighting, there is a tradition that one party goes up into the Cyclops to search for an echidna while the other party goes to the ocean to find a marlin. Both creatures were so difficult to find that it would often take decades or a whole generation to locate them, but, once found, the animals symbolized the end of the conflict and a return to harmonious relationships in the village. The echidna has only been scientifically recorded once, when it was discovered by Pieter van Royen – a Dutch botanist – in 1961. Since then it has only been known from reports of sightings by the Yongsu Sapari community, and indirect signs during pre-expedition work in 2022. These signs, also observed during the expedition, included “nose pokes,” holes in the ground left by echidnas after using their long, slightly curved snouts to probe for underground invertebrates. A Treasure Trove of Discoveries Alongside searching for the echidna, the expedition carried out the first comprehensive assessment of invertebrate, reptile, amphibian, and mammal life in the Cyclops Mountains. With the support of local guides in the expedition team, the scientists were able to create makeshift labs in the heart of the jungle with benches and desks made from forest branches and vines. A new species of terrestial shrimp, found in the soil and in the trees of the Cyclops Mountains. This shrimp belongs to a lineage that is normally found on the seashore, and it was an enormous surprise to the expedition team when it was discovered living hundreds of meters high up on th slopes of the mountains. Credit: Expedition Cyclops By combining scientific techniques with the Papuan team members’ experience and knowledge of the forest, the team made a wealth of new discoveries. These included several dozens of insect species completely new to science and the rediscovery of Mayr’s honeyeater (Ptiloprora mayri), a bird lost to science since 2008 and named after famed evolutionary biologist Ernst Mayr. An extraordinary finding was an entirely new genus of ground and tree-dwelling shrimp. “We were quite shocked to discover this shrimp in the heart of the forest, because it is a remarkable departure from the typical seaside habitat for these animals,” said Dr. Leonidas-Romanos Davranoglou (a Leverhulme Trust Postdoctoral Fellow at the Oxford University Museum of Natural History), lead entomologist for the expedition. “We believe that the high level of rainfall in the Cyclops Mountains means the humidity is great enough for these creatures to live entirely on land.” The team also revealed a treasure trove of underground species, including blind spiders, blind harvestman, and a whip scorpion, all new to science, in a previously unexplored cave system. This astonishing discovery was made on one of the sacred peaks above Yongsu Sapari where the team had been given special permission to do research. People rarely tread here, and the striking cave system was chanced upon when one team member fell through a moss-covered entrance. About the Expedition: The expedition was first proposed in 2019 by James Kempton. Academics who collaborated closely on the expedition include Dr. James Kempton (University of Oxford), Dr. Leonidas-Romanos Davranoglou (Oxford University Museum of Natural History), Madeleine Foote (University of Oxford), Dr. Andrew Tilker (Re:wild, Leibniz Institute for Zoo and Wildlife Research), Dr. Attila Balázs (Mendel University) and Dr. Max Webb (Royal Holloway, University of London). Cenderawasih University (UNCEN) team members and partners include Dr. Suriani Surbakti, Gison Morib and Heron Yando. Team members and collaborators from Indonesian NGO Yayasan Pelayanan Papua Nenda (YAPPENDA) include co-founders Iain and Malcolm Kobak, and Yali Kobak, Sampari Kobak, Ezra Daniel, Ruben Penggu, Melias Heluka, Yuanis Yalak and Sili Yalak. The team obtained permits from Papua BBKSDA and BRIN. They were also given permission from the community of Yongsu Sapari to conduct research and collect specimens on their land during the expedition. This rediscovery was made possible in part by the generous support of Merton College Oxford, the Royal Geographical Society, the Scientific Exploration Society, Re:wild, Royal Holloway University, the University of Oxford, Reconyx, and private donations from Derek Williams, Chris Peri, and other generous individuals. “A Beautiful but Dangerous Land” Extremely challenging and, at times, life-threatening conditions were at the background of these discoveries. During one of the trips to the cave system, a sudden earthquake forced the team to evacuate. Dr. Davranoglou broke his arm in two places, one member contracted malaria, and another had a leech attached to his eye for a day and a half before it was finally removed at a hospital. Throughout the expedition, members were beset by biting mosquitoes and ticks, and faced constant danger from venomous snakes and spiders. Making any progress through the jungle was a slow and exhausting process, with the team sometimes having to cut paths where no humans had ever been before.

Credit: Expedition Cyclops “Though some might describe the Cyclops as a “Green Hell,” I think the landscape is magical, at once enchanting and dangerous, like something out of a Tolkien book,” said Dr. Kempton. “In this environment, the camaraderie between the expedition members was fantastic, with everyone helping to keep up morale. In the evening, we exchanged stories around the fire, all the while surrounded by the hoots and peeps of frogs.” About the Cyclops Mountains: The Cyclops Mountains are one of the most inhospitable regions in the world, being rugged, steep, and dangerous, and ranging from sea level to 1,970 metres. They are dominated by two main peaks – Gunung Rara and Gunung Dafonsoro. When sailing ten leagues from the range’s northern coastline in 1768, Baron Louis de Bougainville noted “les deux cyclopes,” from which the mountains bear their name. The Cyclops Mountains are a Key Biodiversity Area, meaning that they are critical to the persistence of biodiversity and to the overall health of the planet. The community of Yongsu Sapari have lived in the region for eighteen generations and hold the land as sacred. They believe it is stewarded by a female spirit who can take the form of a tree-kangaroo. An Enduring Legacy Rediscovering the echidna is only the beginning of the expedition’s mission. Attenborough’s long-beaked echidna is the flagship animal of the Cyclops Mountains and a symbol of its extraordinary biodiversity. The team hopes that its rediscovery will help bring attention to the conservation needs of the Cyclops, and Indonesian New Guinea more generally, and they are committed to supporting long-term monitoring of the echidna. Key to this work is NGO YAPPENDA, whose mission is to protect the natural environment of Indonesian New Guinea through empowerment of Indigenous Papuans. As part of the expedition team, members of YAPPENDA helped train six students from UNCEN in biodiversity surveys and camera trapping during the expedition. Dr. Davranoglou said: “Tropical rainforests are among the most important and most threatened terrestrial ecosystems. It is our duty to support our colleagues on the frontline through exchanging knowledge, skills, and equipment.” With the team having only sorted a fraction of the material collected on the expedition, they expect that the coming months will yield even more new species. The intention is to name many of these after the Papuan members of the expedition. Besides animal specimens, the team also collected over 75 kg of rock samples for geological analysis, which was led by the expedition’s chief geologist, Max Webb, from Royal Holloway University, London. These could help answer many questions about how and when the Cyclops Mountains originally formed. The mountains are believed to have formed when an island arc in the Pacific Ocean collided with the New Guinea mainland about 10 million years ago. Combined with the biological findings, this geological work will help the team understand how the extraordinary biodiversity of the Cyclops came to be. Researchers have found that collagen contains weak bonds that break under stress, protecting the rest of the tissue. This discovery could provide insights into tissue aging and aid the development of tissue engineering techniques. Above is a collagen triple helix. Credit: Riedmiller / HITS Recent findings about collagen, our body’s most abundant protein, reveal that its sacrificial bonds snap more quickly than the basic structure, thereby protecting the tissue as a whole – they track down harmful radicals that are produced during mechanical stress. One of the more unusual ways objects can increase longevity is by sacrificing a part of themselves: This can range from decoy burial chambers designed to mislead grave robbers, a fuse deliberately melting within an electrical circuit to protect other appliances, or a lizard’s tail detaching to facilitate its escape. This concept of sacrificial elements can also be observed in collagen, the most abundant protein in our bodies. Researchers at the Heidelberg Institute for Theoretical Studies (HITS) have revealed how the rupture of weak sacrificial bonds within collagen tissue helps to localize damage caused by excessive force, minimize negative impacts on the wider tissue, and promote recovery. Published in Nature Communications, the work shines light on collagen’s rupture mechanisms, which is crucial for understanding tissue degradation, material aging, and potentially advancing tissue engineering techniques. “Collagen’s remarkable crosslink chemistry appears to be perfectly adapted to handling mechanical stress,” says Frauke Gräter, who led the research at HITS. “By using complementary computational and experimental techniques to study collagen in rat tissue, our findings indicate that weak bonds within the crosslinks of collagen have a strong propensity to rupture before other bonds, such as those in the collagen’s backbone. This serves as a protective mechanism, localizes the detrimental chemical and physical effects of radicals caused by ruptures, and likely supports molecular recovery processes.” The Structural Complexity of Collagen Collagen comprises roughly 30 percent of all proteins in the human body. It provides strength to bones, elasticity to skin, protection to organs, flexibility to tendons, aids in blood clotting, and supports the growth of new cells. Structurally, collagen resembles a triple-braided helix: Three chains of amino acids intertwine to form a strong and rigid backbone. Each collagen fiber contains thousands of individual molecules that are staggered and bound to each other by crosslinks, contributing to collagen’s mechanical stability. It was thought that collagen crosslinks are susceptible to rupture, however little was known about the specific sites of bond ruptures or why ruptures occur where they do. Scientists from the Molecular Biomechanics Group at HITS aimed to unravel these puzzles using computer simulations of collagen across multiple biological scales and under different mechanical forces. They validated their findings via gel electrophoresis and mass spectrometry experiments conducted on rat tails, flexors, and Achilles’ tendons. By subjecting collagen to rigorous testing, the team was able to determine specific breakage points. They observed how force dissipates through the complex hierarchical structure of the tissue and how its chemical bonds bare the load. Mature crosslinks in collagen consist of two arms: one of which is weaker than other bonds in collagen tissue. When subjected to excessive force, the weaker arm is typically first to rupture, dissipating the force and localizing detrimental effects. The scientists found that in regions of collagen tissue where weak bonds are present, other bonds – both in the crosslinks and the collagen backbone – are more likely to remain intact, thereby preserving the structural integrity of the collagen tissue. Preventing Oxidative Stress and Tissue Degradation Previous work led by HITS scientists revealed that excessive mechanical stress on collagen leads to the generation of radicals, which in turn cause damage and oxidative stress in the body. “Our latest research shows that sacrificial bonds in collagen serve a vital role in maintaining the overall integrity of the material can help to localize the impacts of this mechanical stress that could otherwise have catastrophic consequences for the tissue,” explains Benedikt Rennekamp, the study’s first author. “As collagen is a major substituent of tissues in our bodies, by uncovering and understanding these rupture sites, researchers can gain valuable insights into the mechanics of collagen and potentially develop strategies to enhance its resilience and mitigate damage.” Reference: “Collagen breaks at weak sacrificial bonds taming its mechanoradicals” by Benedikt Rennekamp, Christoph Karfusehr, Markus Kurth, Aysecan Ünal, Debora Monego, Kai Riedmiller, Ganna Gryn’ova, David M. Hudson and Frauke Gräter, 12 April 2023, Nature Communications. DOI: 10.1038/s41467-023-37726-z The study was funded by the H2020 European Research Council and Klaus Tschira Stiftung. DNA damage can persist unrepaired for years, particularly in blood stem cells, increasing the risk of mutations and cancer. This discovery challenges traditional views on mutation processes and highlights the need for further research to understand and address the causes of such persistent damage. In a groundbreaking shift in our understanding of mutations, researchers have discovered types of DNA damage in healthy cells that can remain unrepaired for years. While most types of DNA damage are repaired by the body’s natural DNA repair mechanisms, some forms of damage can evade these processes and persist for years, according to new research. This prolonged presence increases the likelihood of generating harmful mutations, which may eventually lead to cancer. Scientists from the Wellcome Sanger Institute and their collaborators studied the family trees of hundreds of single cells from several individuals. By analyzing shared mutation patterns among cells, they reconstructed these family trees, identifying common ancestral origins. Their findings revealed surprising patterns of mutation inheritance, indicating that certain DNA damage remains unrepaired over extended periods. For example, in blood stem cells, some forms of damage can persist for two to three years. The research, published in Nature, changes the way we think about mutations, and has implications for understanding the development of various cancers. Throughout our life, all of the cells in our body accumulate genetic errors in the genome, known as somatic mutations. These can be caused by damaging environmental exposures, such as smoking, as well as the everyday chemistry occurring in our cells. Mutation Origins and Persistent Damage DNA damage is distinct from a mutation. While a mutation is one of the standard four DNA bases (A, G, T or C) in the wrong place, similar to a spelling mistake, DNA damage is chemical alteration of the DNA, like a smudged unrecognizable letter. DNA damage can result in the genetic sequence being misread and copied during cell division – known as DNA replication – and this introduces permanent mutations that can contribute to the development of cancers. However, the DNA damage itself is usually recognized and mended quickly by repair mechanisms in our cells. If researchers can better understand the causes and mechanisms of mutations, they may be able to intervene and slow or remove them. In a new study, Sanger Institute scientists and their collaborators analyzed data in the form of family trees of hundreds of single cells from individuals. The family trees are constructed from patterns of mutations across the genome that are shared between cells – for example, cells with many shared mutations have a recent common ancestor cell and are closely related. The researchers collated seven published sets of these family trees, known as somatic phylogenies. The data set included 103 phylogenies from 89 individuals, spanning blood stem cells, bronchial epithelial cells, and liver cells. The team found unexpected patterns of mutation inheritance in the family trees, revealing that some DNA damage can persist unrepaired through multiple rounds of cell division. This was particularly evident in blood stem cells, where between 15 to 20 percent of the mutations resulted from a specific type of DNA damage that persists for two to three years on average, and in some cases longer. Implications for Cancer Development This means that during cell division, each time the cell attempts to copy the damaged DNA it can make a different mistake, leading to multiple different mutations from a single source of DNA damage. Importantly, this creates multiple chances of harmful mutations that could contribute to cancer. Researchers suggest that although these types of DNA damage occur rarely, their persistence over years means they can cause as many mutations as more common DNA damage. Overall, these findings change the way researchers think about mutations, and have implications for the development of cancer. Dr Michael Spencer Chapman, first author from the Wellcome Sanger Institute and the Barts Cancer Institute, said: “With these family trees, we can link the relationships of hundreds of cells from one person right back to conception, meaning we can track back through the divisions each cell has gone through. It’s these large-scale, novel datasets that have led us to this unexpected finding that some forms of DNA damage can last for a long time without being repaired. This study is a prime example of exploratory science – you don’t always know what you’re going to find until you look; you have to stay curious.” Emily Mitchell, an author from the Wellcome Sanger Institute, Wellcome-MRC Cambridge Stem Cell Institute and University of Cambridge, said: “When exploring family trees of blood stem cells in particular, we found a specific type of DNA damage that results in around 15 to 20 percent of the mutations in these cells, and can last for several years. It is unclear why this process is only found in blood stem cells and not other healthy tissues. Knowing that the DNA damage is long-lasting gives new routes to investigate what the damage actually is. As we continue to better understand the causes of mutations, we may one day be able to intervene and remove them.” Dr Peter Campbell, lead author previously from the Wellcome Sanger Institute and now Chief Scientific Officer at Quotient Therapeutics, said: “We have identified forms of DNA damage that manage to escape our DNA repair mechanisms and persist in the genome for days, months, or sometimes years. These findings don’t fit with what scientists have previously thought about the fundamentals of how mutations are acquired. This paradigm shift brings a new dimension to the way we think about mutations, and is important for the research community when designing future studies.” Reference: “Prolonged persistence of mutagenic DNA lesions in somatic cells” by Michael Spencer Chapman, Emily Mitchell, Kenichi Yoshida, Nicholas Williams, Margarete A.
