Dr. 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. 
Published: Jun 17 2025, 8 pmeznews.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.
Published: 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.
Published: 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.
Published: Jun 18 2025, 12 ameznews.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*.
Published: 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*.
Published: Jun 15 2025, 10 pmeznews.inCancer remains a leading global health challenge, responsible for 9.7 million deaths in 2022, with lung cancer being the most lethal, claiming 1.8 million lives worldwide. In the United States, it is estimated that one in four individuals will be diagnosed with cancer in their lifetime, with lung, colon, pancreatic, and breast cancers contributing significantly to mortality rates. Notably, while breast cancer has a high mortality rate, it also boasts a five-year survival rate of 99.3%. Disparities in cancer mortality are evident, with men, particularly non-Hispanic black men, facing higher rates than women. Geographic differences also highlight healthcare access issues, as seen in contrasting mortality rates between Mississippi and Hawaii. However, advancements in treatment and lifestyle changes have led to a decline in cancer deaths in the U.S., with promising new therapies and personalized vaccines currently in development.
Published: Jun 17 2025, 5 pmeznews.inFrance holds the record for the most time zones of any country, with 12 distinct zones (13 if including its Antarctic claim), according to Guinness World Records. This surprising statistic stems from France's numerous overseas territories, which span the globe from French Polynesia to the Caribbean and the Indian Ocean. The time zones range from UTC−10:00 in French Polynesia to UTC+12:00 in Wallis and Futuna. While the world is divided into 38 observed time zones, most countries operate within a single zone, with Russia and the USA each having 11. Notably, China, despite covering nearly five geographical time zones, adheres to a single time zone, Beijing Time, while India also maintains one time zone for national unity, leading to significant variations in sunrise and sunset times across its vast territory.
Published: Jun 17 2025, 8 ameznews.inThe cowgirl position, also known as the cowboy or rider position, is a popular penetrative sex position where the receiving partner sits atop the penetrating partner, typically facing each other. This position allows for various adaptations, including the reverse cowgirl and horizontal cowgirl, enhancing intimacy and pleasure. It is particularly favored for its potential to stimulate the clitoris, making it the second most popular choice for men and the third for women, according to sex experts. However, caution is advised, as studies indicate that about 50% of penile fractures during sex occur in this position, often due to erratic thrusting. Communication between partners is essential to ensure comfort and enjoyment, thereby minimizing risks. Overall, the cowgirl position remains a versatile and widely appreciated choice for couples looking to explore their sexual dynamics.
Published: Jun 17 2025, 12 pmeznews.inIn the animated film _Finding Nemo_, a scene featuring Bruce the shark raises an intriguing question about the function of shark nostrils, or nares, given that sharks lack lungs. Unlike humans, who rely on lungs to draw in air for smelling, sharks have a distinct olfactory system that operates separately from their respiratory system. Their nares contain a complex structure called a rosette, which detects odors in water, allowing sharks to locate prey effectively. Water flows into the nares as sharks swim, or through tiny cilia-like hairs, facilitating the detection of scents. Research by Jelle Atema from Boston University reveals that sharks not only track the highest concentration of odors but also consider water currents, enhancing their hunting efficiency. Thus, while sharks have nostrils, they serve a unique purpose in olfaction rather than respiration, underscoring the evolutionary adaptations of these marine predators.
