North America is a diverse continent comprising 23 independent countries, including not only the well-known trio of the United States, Canada, and Mexico, but also nations in Central America and the Caribbean. These include Antigua and Barbuda, Cuba, Jamaica, and Panama, among others. Additionally, the continent features 23 non-self-governing territories, such as Puerto Rico and the British Virgin Islands. The definition of continents is complex and varies globally, with some arguing for as few as two continents based on geological criteria. The North American tectonic plate extends beyond the continent's political boundaries, encompassing regions like Greenland and parts of Siberia and Japan. Ultimately, the classification of continents is influenced by a mix of political, cultural, and historical factors, alongside geological considerations. 
Published: Nov 13 2025, 10 pmeznews.inA recent study suggests that intimacy with a partner can accelerate the healing of physical wounds, with the effects enhanced by the hormone oxytocin, often dubbed the "love hormone." Researchers applied small blister wounds to the forearms of 80 heterosexual couples, dividing them into groups that received either oxytocin nasal spray or a placebo, alongside a "Partner Appreciation Task" (PAT) involving compliments. While oxytocin alone did not speed healing, combining it with the PAT resulted in faster recovery, particularly for couples who also engaged in sexual activity. The study found that higher sexual activity correlated with lower cortisol levels, indicating reduced stress may play a role in healing. Notably, even daily affectionate touch, when paired with oxytocin, contributed to quicker recovery, suggesting that oxytocin enhances the benefits of intimacy rather than acting independently. The findings are published in JAMA Psychiatry.

While many people may instinctively apply these products after showering, nighttime application allows the aluminium salts to dissolve into sweat and form a gel-like plug in the sweat glands, preventing perspiration throughout the day. This method takes advantage of lower sweat production at night, ensuring optimal results by morning. Although antiperspirants create a temporary barrier, they do not cause sweat glands to swell, as the skin's natural feedback system regulates sweating. For those looking to stay dry and confident, applying antiperspirant before bed is the recommended approach, allowing for a fresh start to the day ahead.
Published: Nov 13 2025, 10 pmeznews.inA new study has provided insights into the non-gravitational acceleration observed in comet 3I/ATLAS, our third confirmed interstellar visitor. Researchers, led by Florian Neukart from Leiden University, suggest that this acceleration can be explained by conventional outgassing of volatiles, such as carbon dioxide and water, rather than invoking exotic or non-natural hypotheses. The comet, which was first detected on July 1, 2025, has exhibited typical cometary behavior, including the release of water as it approaches the Sun. Measurements indicate a radial acceleration of 135 kilometers per day squared and a transverse acceleration of 60 kilometers per day squared. The findings, which are yet to undergo peer review, challenge previous theories that proposed unusual mechanisms for the comet's behavior. Further observations are anticipated to refine our understanding of this intriguing celestial object, which may hold clues about the early universe.
Published: Nov 13 2025, 10 pmeznews.inIn a fluorescent-lit room, a captivated audience watched as snake venom extractors demonstrated the delicate process of "milking" a medium-sized snake, which injected venom into a collection dish. Carl M. Barden, Director of Medtoxin Venom Laboratories, shared his lifelong passion for snakes, particularly the King Cobra and Eastern Coral Snake. With an estimated 5.4 million snakebites globally each year, the World Health Organization has prioritized snakebite envenomation as a neglected tropical disease, aiming to halve mortality rates by 2030. Experts emphasize that immediate hospital treatment is crucial for survival, as traditional remedies are ineffective. While antivenoms remain the primary treatment, challenges such as specificity and supply shortages persist. Innovative research is underway, exploring lab-grown venom glands and oral treatments like unithiol, which could revolutionize snakebite care. Despite advancements, the reliance on snake milking continues, highlighting the ongoing need for effective solutions in snakebite management.
Published: Nov 14 2025, 1 ameznews.inScientists have confirmed that it is theoretically possible to create gold in a laboratory setting, but the process is highly inefficient and prohibitively expensive. Most of Earth's gold originated from cosmic events, such as supernovae and neutron star collisions, which fused lighter elements into heavy metals. Modern techniques, including nuclear reactions and particle accelerators, can replicate this process. For instance, experiments have shown that bombarding mercury or platinum with neutrons can yield radioactive gold isotopes, while the Large Hadron Collider at CERN has produced gold by smashing lead nuclei together, creating fleeting amounts of the precious metal. However, these methods require immense energy and resources, with costs potentially exceeding one quadrillion dollars per ounce, as highlighted by Nobel laureate Glenn Seaborg's experiments in the 1980s. Thus, while alchemists may rejoice at the possibility, practical applications remain elusive.
Published: Nov 13 2025, 5 pmeznews.inA recent study from the University of Silesia and the University of Padova has unveiled the complex motivations behind men's decision to grow beards, linking facial hair to social status, competition, and family care. The research, which surveyed 414 men aged 18 to 40, found that bearded men are often perceived as healthier, more trustworthy, and better suited for fatherhood, suggesting that beards may signal a shift from short-term mating to long-term relationships. Interestingly, while men with facial hair were more inclined to value family care, those who reported higher competitiveness did not necessarily have more facial hair. The study highlights that motivations for beard maintenance are multifaceted, encompassing both affiliative and competitive aspects, and calls for further research to explore the nuances of facial hair styles and their implications. The findings are published in the *Archives of Sexual Behavior*.
Published: Nov 13 2025, 11 pmeznews.inA groundbreaking study from Stanford Medicine has established a link between the Epstein-Barr virus (EBV) and lupus, a chronic autoimmune disease affecting over 5 million people globally. The research reveals that while EBV infects fewer than 1 in 10,000 B cells in healthy individuals, this figure rises to 1 in 400 in lupus patients. The study identifies a "molecular switch" gene activated by EBV in infected B cells, triggering a cascade of pro-inflammatory responses that lead to the immune system attacking the body’s own tissues. Senior author Dr. William Robinson emphasized the significance of this finding, suggesting it could apply to all lupus cases. However, the study notes that not all EBV-infected individuals develop lupus, indicating that specific strains of the virus may play a role in this transformation. The findings are published in *Science Translational Medicine*.
Published: Nov 13 2025, 9 pmeznews.inA recent study has shed light on the perplexing condition of Long COVID, which can persist for months or years after the initial infection, manifesting in over 200 symptoms. Researchers followed 24 COVID-19 patients for up to 900 days, focusing on T cells—immune cells that may play a crucial role in the condition. Unlike previous studies, this research utilized PET scans to observe T cell behavior, revealing patterns of long-term activation in various body parts, including the lungs and gut, where COVID-19 RNA was also detected. While the study does not definitively clarify whether these T cells are responding to remnants of the virus or active particles, it suggests that some individuals may harbor viral reservoirs in their tissues. Experts believe this research could pave the way for targeted treatments, addressing the urgent need for new clinical trials for the millions affected by Long COVID. The findings are published in *Science Translational Medicine*.
Published: Nov 13 2025, 6 pmeznews.inAs Thanksgiving approaches, health experts warn against the common practice of washing raw turkey, which can lead to serious foodborne illnesses. Washing the bird can spread harmful bacteria like Salmonella and Campylobacter, potentially contaminating surfaces and other foods within a five-foot radius, according to Janell Goodwin from the USDA. This risk is particularly concerning during the holiday season, as nearly one million cases of food poisoning from Clostridium perfringens occur annually in the U.S., with a spike in November and December. To ensure safety, it is crucial to wash hands thoroughly before and after handling raw turkey, cook it to an internal temperature of 165°F (73.9°C), and refrigerate leftovers within two hours. Following these guidelines can help prevent unpleasant symptoms such as diarrhea and nausea, allowing families to enjoy their Thanksgiving feast without health concerns.
