A groundbreaking study has revealed that dinosaurs may have had a softer side, specifically chubby cheeks, challenging long-held perceptions of their anatomy. Researchers examined the external skull morphology of various dinosaur species, discovering evidence of soft buccal tissue—termed "exoparia"—that connects the zygoma and mandible. This finding suggests that dinosaurs possessed a strong connective tissue structure that could stabilize their jaws during chewing, akin to mammalian anatomy. The study employed a novel methodology called THLEEP (Three-dimensional HistoLogical Enthesis Entry-angle Prediction) to analyze the orientation of these missing tissues. While no fossilized cheeks exist to confirm this hypothesis, the implications for understanding dinosaur feeding habits and skull anatomy are significant, hinting at a more complex chewing mechanism than previously thought. The research is published in the Journal of Anatomy, potentially reshaping our view of these ancient creatures.

May 30 2025, 9 pmeznews.inIn a remarkable archaeological find, seven ancient funerary urns containing human and turtle remains have been unearthed in the Brazilian Amazon, following the fall of a tree in a remote area. Discovered at the Cochila Lake archaeological site, these urns, two of which are notably large, are believed to date back to pre-Hispanic times, although their exact cultural affiliation remains uncertain. Archaeologist Geórgea Layla Holanda noted that the urns, buried approximately 40 centimeters deep, lacked ceramic lids, suggesting they were sealed with organic materials that have since decomposed. The contents, which include human bones and animal remains, may provide insights into ancient funerary customs and dietary practices. The urns were excavated with local villagers' assistance and are now undergoing analysis in Tefé, potentially shedding light on a previously unknown multicultural society that thrived in the region.

Jun 16 2025, 10 pmeznews.inIn a significant geological revelation, Zealandia, officially recognized as a continent in 2017, has been the subject of a comprehensive review detailing its tectonic history and geological evolution. Spanning approximately 5 million square kilometers, with 95% submerged, Zealandia is primarily represented by New Zealand and New Caledonia. Dr. Nick Mortimer, an Emeritus Geologist, highlighted that Zealandia was once part of the Gondwana supercontinent before separating 85 to 60 million years ago. Its unique geological structure features small landmasses and extensive submarine shelves, contributing to its underwater dominance. The region is geologically complex, straddling the Pacific and Australian tectonic plates, which results in frequent earthquakes and volcanic activity. Experts emphasize that Zealandia's geological record is crucial for understanding past ocean-climate systems and the evolution of life, while many questions about its formation and features remain unanswered. The findings are published in the New Zealand Journal of Geology and Geophysics.

Jun 18 2025, 4 ameznews.inA puzzling physics problem has emerged on Reddit, where users are questioning why a specific contraption, featuring interconnected wheels, fails to turn. The issue arises from the mechanics of the system: if a larger wheel completes one rotation in a minute, a smaller wheel connected to it would theoretically rotate three times in the same period. However, this smaller wheel is also linked to another large wheel, which is only turning once per minute. This creates a paradox where the smaller wheel must rotate at both one and nine times per minute simultaneously, an impossible scenario. The outcome hinges on the friction between the wheels; if they are too grippy, the mechanism will jam, while excessive lubrication could allow for some movement. Ultimately, the contraption illustrates the complexities of mechanical systems and the challenges of achieving perpetual motion.

Jun 17 2025, 11 pmeznews.inA recent study has revealed that a child buried over 100,000 years ago in Skhul Cave, Israel, may represent a hybrid between Neanderthals and modern humans, challenging previous assumptions about early burial practices. This child, likely a girl aged three to five, was initially classified as a transitional form between the two species but is now recognized as anatomically modern. Researchers conducted CT scans and 3D modeling of the child's skull, finding that while the cranial structure aligns with Homo sapiens, the jaw exhibits Neanderthal characteristics. This suggests a complex interplay of human species in the Levant during the Middle Paleolithic era, indicating that early burial customs cannot be solely attributed to Homo sapiens. The findings raise questions about the lineage of the adults who buried the child and hint at the possibility of an unknown indigenous lineage in the region. The study has been published in the journal l’Anthropologie.

Jun 17 2025, 10 pmeznews.inEarth's crust is in a constant state of flux, as illustrated by a new one-minute video showcasing the movement of tectonic plates over the past 1.8 billion years, a mere 40% of the planet's history. Produced by Australian and Chinese geologists, the video begins in the 21st century and traces the formation of supercontinents like Pangaea and Rodinia, challenging the notion of the "boring billion" period, previously thought to be geologically stable. Current geological activity continues, with Zealandia recognized as a submerged continent and East Africa's rift potentially leading to the creation of a new ocean in the next 5 to 10 million years. Looking ahead, scientists predict the emergence of a new supercontinent in about 200 million years, with scenarios including "Amasia," where continents cluster around the North Pole, or "Aurica," where they gather at the equator, indicating a dramatically different Earth in the future.

Jun 18 2025, 12 ameznews.inDr. Ana Gracanin from the Australian National University has made a remarkable discovery about greater gliders, a lesser-known marsupial species, by using an infrared camera placed inside a tree hollow. Contrary to previous beliefs that male gliders were uninvolved in parenting, Gracanin observed a male glider, Milo, delivering eucalyptus stems to his young, Brimi, using his tail. This behavior, along with the gliders' prehensile tails, challenges assumptions about their solitary nature and highlights their vulnerability to habitat loss, particularly as they rely on old trees for nesting. Gracanin's livestream project, which required extensive setup, aims to shed light on the private lives of these creatures, revealing their dependence on family-sized hollows for survival. With significant population declines following recent bushfires and ongoing threats from climate change, conservation efforts are critical to protect these adorable animals and their habitats.

Jun 17 2025, 8 pmeznews.inIn Central Chile, a live demonstration highlights the critical relationship between plants and animals in seed dispersal, particularly as many plant species face isolation and endangerment due to their reliance on extinct megafauna like mastodons. Research led by Professor Florent Rivals reveals that the Pleistocene mastodon, _Notiomastodon platensis_, consumed fruits, including those of the Chilean palm, aiding in seed distribution across vast areas. However, with 40% of the fruit species that once thrived in these ecosystems now threatened, the loss of large animal dispersers has dire consequences for plant survival. In contrast, regions with surviving seed-dispersing animals, such as tapirs and monkeys, show significantly lower rates of endangerment among large fruiting plants. The study underscores the long-lasting impacts of severed ecological relationships and the urgent need for conservation efforts to preserve these unique plant populations, as highlighted in the journal *Nature Ecology and Evolution*.

Jun 17 2025, 2 ameznews.inResearchers at Tufts University School of Medicine have developed a groundbreaking dental implant that aims to replicate the sensory experience of natural teeth. Traditional implants, which involve fusing titanium posts to the jawbone, often lack the nerve connections that provide feedback during eating and speaking. The new implant features a biodegradable coating that releases stem cells and proteins to promote nerve tissue growth, allowing the implant to connect to the body's sensory system. Additionally, the coating contains memory foam-like particles that enable the implant to expand and fit snugly in the socket, preserving surrounding nerve endings. Initial tests on rats showed promising results, with no signs of inflammation or implant displacement, and evidence of integration through soft tissue rather than bone fusion. While these findings are encouraging, further research is necessary to assess the implants' safety and effectiveness in other animal models before human trials can begin. The study is published in *Scientific Reports*.
