A recent study suggests that women who engage in sexual activity less than once a week may face a higher risk of early mortality compared to those who have sex more frequently. The research, which analyzed data from 14,542 individuals in the US, found that women with low sexual frequency were 1.7 times more likely to die from any cause by the end of 2015. While this trend was not observed in men, both sexes with depression showed a significant increase in mortality risk associated with infrequent sexual activity. The authors propose that sexual activity may enhance cardiovascular health and mitigate age-related functional decline. Although causation cannot be definitively established, previous studies indicate that sexual activity can improve mood and overall well-being. The findings, published in the Journal of Psychosexual Health, suggest that while a weekly sexual encounter may not guarantee longevity, it could contribute positively to health. 
Published: Apr 09 2025, 9 ameznews.inScientists at the University of Tokyo have developed a groundbreaking method to create nugget-sized chicken meat in a bioreactor, utilizing a perfusable hollow fiber system that mimics blood vessels to efficiently deliver nutrients and oxygen to lab-grown tissues. This innovative approach not only enhances cell survival but also improves muscle structure, texture, and taste, potentially revolutionizing the cultured meat industry. Senior author Shoji Takeuchi emphasized that this scalable technology could lead to fully automated production of whole-cut cultured meat, offering a sustainable and ethical alternative to traditional meat. However, consumer acceptance remains a challenge, with a 2024 poll revealing that 33% of Americans are hesitant to try cultivated chicken. Additionally, environmental concerns have been raised, suggesting that large-scale production could emit significantly more greenhouse gases than conventional beef. The findings are detailed in the journal *Trends in Biotechnology*.
Published: Apr 17 2025, 8 pmeznews.inResearchers at UCL have pinpointed critical brain regions involved in logical thinking and problem-solving, enhancing our understanding of reasoning skills essential for various intellectual pursuits. Utilizing lesion-deficit mapping, the study examined 247 patients with unilateral brain lesions and 81 healthy controls, employing verbal and nonverbal reasoning tests. Results indicated that individuals with damage to the right frontal lobe struggled significantly more with reasoning tasks, making 15% more errors than those with lesions in other areas. Lead author Dr. Joseph Mole emphasized the study's potential to improve diagnosis and treatment of cognitive impairments. The findings reveal a strong link between the right frontal brain network responsible for reasoning and fluid intelligence, suggesting a shared neural basis. The researchers advocate for the implementation of their new tests within the UK's National Health Service to better assess right frontal lobe dysfunction, with the study published in the journal *Brain*.
Published: Apr 17 2025, 9 pmeznews.inA puzzling discovery at Shanidar Cave in northern Iraq, where Neanderthal remains were found alongside significant pollen deposits, has sparked debate among scientists regarding ancient burial practices. Initially thought to indicate elaborate funerary rituals, recent research suggests that the pollen may have been deposited by nesting solitary bees rather than by humans or animals transporting flowers. The study, published in the Journal of Archaeological Science, highlights that the pollen mixture found around the grave is inconsistent with the idea of whole flowers being placed there, pointing instead to bees foraging from various plant species. While the "Flower Burial" hypothesis remains contentious, researchers emphasize that the true significance of the site lies in its unique cluster of Neanderthal burials, which may offer deeper insights into their spatial awareness and social behaviors, rather than the presence of flowers.
Published: Apr 17 2025, 8 pmeznews.inA significant shift in religious life is occurring across the United States, with a growing number of individuals identifying as "nones," or those with no formal religious affiliation but some spiritual beliefs. This demographic has surged from 5% to over 25% since 2003, according to a Cornell-led study. Researchers found that this trend reflects broader social changes, including a focus on individual fulfillment, evolving views on gender and sexuality, and a backlash against increasingly bureaucratic religious institutions. The study, which analyzed data from over 1,300 participants in the National Study of Youth and Religion, revealed a notable decline in religious attendance and affiliation, particularly among more liberal individuals. However, belief in God and personal spirituality remain stable, with many seeking alternative spiritual practices like meditation. The findings suggest that this movement away from organized religion is driven by a desire for authenticity and alignment with personal values rather than a rejection of spirituality itself.
Published: Apr 16 2025, 9 pmeznews.inIn a groundbreaking discovery, astronomers have identified a rare brown dwarf binary system, 2M1510, which is believed to be orbited by a planet in a unique "polar" orbit—perpendicular to the plane of the brown dwarfs. This finding marks only the second instance of an eclipsing binary system composed entirely of brown dwarfs, which are stellar objects that lack the mass to ignite hydrogen fusion. Lead researcher Thomas Baycroft from the University of Birmingham noted that the brown dwarfs exhibit eccentric, precessing orbits, suggesting the presence of a planet influencing their motion. While the exact nature of the candidate planet remains uncertain, it is theorized to be a gas giant, potentially formed in a misaligned orbit or influenced by an undetected third brown dwarf. The team plans to continue observations to gather more data, with hopes of capturing another eclipse to refine their understanding of this intriguing system. The findings are detailed in the journal Science Advances.
Published: Apr 17 2025, 12 ameznews.inRecent studies have unveiled the complex environment of Lake Whillans, a subglacial lake beneath Antarctica's ice, which is not just a frozen wasteland but a dynamic ecosystem. Once covered in lush forests during the Cretaceous period, Antarctica now harbors Lake Whillans, which lies 800 meters beneath the ice and features both fresh and salty water. Research indicates that the lake drains periodically, causing the overlying ice to move more rapidly. Notably, the lake's ecosystem, despite being isolated from sunlight for up to a million years, contains a surprising density of life, akin to that found in the ocean's depths. The studies suggest that the lake's current state is relatively young, having formed in the last few decades, primarily from melting ice. Lake Whillans is just one of nearly 400 subglacial lakes in Antarctica, highlighting the continent's hidden ecological richness.
Published: Apr 17 2025, 5 pmeznews.inThe French Republican calendar, introduced during the late 18th century as a radical alternative to the Gregorian calendar, aimed to reflect the revolutionary ideals of reason and secularism. Established on September 21, 1792, it featured 12 months of 30 days each, divided into three 10-day décades, with names inspired by natural phenomena, such as Vendémiaire for "vintage" and Frimaire for "frost." However, the calendar struggled to gain traction, facing challenges in coordination with countries still using the Gregorian system and resistance from a populace deeply rooted in religious traditions. Despite the revolutionary fervor in Paris, many French citizens found it difficult to abandon centuries of established customs. Ultimately, the calendar was phased out under Napoleon, officially replaced by the Gregorian calendar on January 1, 1806, highlighting the enduring power of tradition over rational reform.
Published: Apr 17 2025, 6 pmeznews.inOn March 7, 2025, protestors gathered in Washington Square Park for the "Stand Up for Science" rally, voicing their opposition to cuts in government research funding. The rally followed the US Department of Health and Human Services' announcement of a controversial study into the debunked link between vaccines and autism, led by Robert F. Kennedy Jr. Despite overwhelming scientific evidence disproving any connection, Kennedy claimed that a definitive cause for rising autism diagnoses would be revealed by September. Experts criticized this assertion, highlighting the complexity of autism, which is influenced by genetic and environmental factors, rather than a single cause. The term "epidemic" used by Kennedy to describe autism was also contested, as many advocate for acceptance and celebration of neurodiversity. The scientific community remains concerned about the implications of pursuing unfounded theories while neglecting established research.
Published: Apr 14 2025, 8 pmeznews.inScientists have identified a remarkably bitter compound derived from the bitter bracket mushroom, _Amaropostia stiptica_, which is found in woodlands across several regions, including Great Britain and North America. Researchers from the Leibniz Institute for Food Systems Biology and the Leibniz Institute of Plant Biochemistry isolated three new bitter compounds and discovered that one, oligoporin D, activates a specific human bitter taste receptor, TAS2R46, even at extremely diluted concentrations. This research sheds light on the largely unexplored realm of bitterness, which is underrepresented in existing databases, primarily dominated by compounds from flowering plants. While the ability to detect bitterness is often linked to avoiding toxins, the study suggests that not all bitter substances are harmful. The findings could have implications for food and health research, potentially aiding in the development of foods that enhance digestion and satiety. The study is published in the Journal of Agricultural and Food Chemistry.
Published: Apr 15 2025, 8 ameznews.inImposter syndrome, a psychological phenomenon where individuals doubt their accomplishments despite evident success, affects many, including high-achieving professionals. A notable anecdote involves Neil Armstrong, who, despite being the first man on the moon, expressed feelings of inadequacy at a gathering of esteemed individuals. This sentiment resonates with many who, like Armstrong, struggle to accept their abilities, often believing they are frauds. Research indicates that while women and ethnic minorities may experience imposter syndrome more intensely, it can affect anyone, particularly those with anxiety or depression. A recent study from Denmark highlights that individuals with these mental health issues often overlook their successes, focusing instead on perceived failures. Experts suggest that positive feedback and reframing self-perception can help combat these feelings. Ultimately, recognizing that even the most accomplished individuals can feel like imposters may provide solace to those grappling with similar insecurities.
