The 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.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.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.
Published: Jun 13 2025, 2 ameznews.inA newly discovered dinosaur species, _Khankhuuluu mongoliensis_, has been unearthed in Mongolia, marking a significant addition to the tyrannosaur lineage. Named after the Mongolian term for "dragon prince," this relatively small dinosaur weighed approximately 750 kilograms and measured about 4 meters in length. Fossils indicate that _Khankhuuluu_ is the closest known ancestor to the iconic tyrannosaurs, suggesting a pivotal evolutionary shift that led to the migration of smaller species from Asia to North America around 85 million years ago. This discovery challenges previous assumptions about the tyrannosaur family tree, revealing that smaller "Pinocchio" rexes were not primitive but rather highly evolved relatives of larger giants like _Tyrannosaurus rex_. Researchers, including Dr. Darla Zelenitsky, emphasize that this finding has reshaped our understanding of tyrannosaur evolution, clarifying relationships within this fascinating group of dinosaurs. The study is published in the journal *Nature*.
Published: Jun 13 2025, 4 pmeznews.inChevrotains, a group of ten small, elusive species in the family Tragulidae, inhabit warmer regions of Southeast Asia, India, and Africa. Despite their name, they are neither mice nor deer but are classified as ungulates and ruminants, possessing a four-chambered stomach. Typically solitary and shy, these herbivores measure around 30 centimeters tall and weigh between 1 to 15 kilograms, with the Java mouse deer being the smallest. Notably, male chevrotains have tusk-like fangs used in territorial disputes. The silver-backed chevrotain, or Vietnamese mouse-deer, was rediscovered in 2019 after being thought lost since 1907, highlighting conservation efforts. The Balabac mouse-deer is currently listed as "Endangered" by the IUCN, facing threats from poaching and habitat loss due to agricultural expansion. Chevrotains play a crucial role in their ecosystems, with the water chevrotain adept at evading predators by submerging in water.
Published: Jun 17 2025, 3 ameznews.inA recent study led by Stephen Kagan has delved into the vivid experiences of individuals using N,N-Dimethyltryptamine (DMT), a powerful psychedelic. Analyzing 100 trip reports sourced from platforms like YouTube and Erowid, Kagan categorized the experiences into five main areas: Places, Objects, Entities, Feelings, and Attributes. Users frequently reported encounters with complex visual phenomena, synesthesia, and autonomous entities, often describing these experiences as more "real than real." Notably, humanoid entities were the most commonly reported, with descriptions ranging from alien-like figures to mythic beings. Kagan emphasized the need for further research into DMT's effects, particularly as movements advocating for its legalization gain momentum. He suggested that understanding these experiences could enhance therapeutic applications, potentially positioning DMT as a more manageable clinical treatment compared to psilocybin, given its rapid onset. The findings underscore the profound and transformative nature of DMT experiences, warranting deeper investigation.
Published: Jun 17 2025, 1 ameznews.inThe European Space Agency (ESA) has successfully conducted its first artificial solar eclipse using the Proba-3 mission, allowing scientists to study the Sun's corona in unprecedented detail. Positioned 150 meters apart, the two spacecraft—an Occulter and a Coronagraph—achieve precise alignment to block the Sun's light, creating a shadow that enables extended solar observations. Principal Investigator Andrei Zhukov expressed excitement over the initial images, noting that the artificial eclipse can last up to six hours, compared to the fleeting moments of natural eclipses. This innovative approach not only enhances understanding of solar phenomena like solar wind and coronal mass ejections but also overcomes limitations of traditional coronagraphs that struggle with optical distortions. ESA's Director of Technology, Dietmar Pilz, highlighted the mission's technological advancements, marking Proba-3 as a pioneering effort in precision formation flying and solar research.
Published: Jun 16 2025, 10 pmeznews.inA particle detector operating above Antarctica has recorded unusual radio pulses from beneath the ice, raising questions about their origin. The Antarctic Impulsive Transient Antenna (ANITA) experiment, which uses a stratospheric balloon to detect cosmic neutrinos, encountered two anomalous radio signals that appear to contradict current particle physics understanding. Stephanie Wissel, an associate professor at Penn State University, noted that the signals came from steep angles, suggesting they traveled through 6,000-7,000 kilometers of rock before reaching the ice, where they should have been absorbed. The team ruled out neutrinos as the source, as similar upward-traveling air showers were not detected by other observatories like IceCube and the Pierre Auger Observatory. Wissel speculated that the anomalies could indicate new physics, and expressed hope that future experiments, such as PUEO, might provide further insights into these mysterious signals. The findings are detailed in Physical Review Letters.
