A recent study has revealed that the unique variations in human ears can be as reliable for identification as fingerprints. One notable feature is Darwin's tubercle, a small bump on the outer ear, considered a vestigial trait from our evolutionary past. While Charles Darwin first described this feature in his work *The Descent of Man*, misconceptions persist regarding its genetic inheritance. Research indicates that the presence of Darwin's tubercle varies significantly across populations, with 10.5% of adults in Spain, 40% in India, and 58% of Swedish schoolchildren exhibiting it. Genetic studies suggest that its occurrence is influenced by a combination of genetic and environmental factors rather than a simple dominant-recessive relationship. Although the tubercle may have once aided in sound amplification, modern human ears have adapted for nuanced communication, making this trait a fascinating example of human diversity. 
Published: Mar 22 2025, 6 pmeznews.inNikola Tesla, the renowned inventor and pioneer of alternating current, is celebrated for his groundbreaking contributions to science, yet he also held some notably incorrect beliefs. Among these was his rejection of electrons, adhering instead to the outdated notion that atoms were the universe's smallest building blocks. In 1899, Tesla claimed to have detected mysterious radio signals, which he speculated could be communications from intelligent extraterrestrial life. Describing the signals as periodic beeps, he dismissed natural sources, convinced they were intentional. Despite initial skepticism and ridicule from contemporaries, a 2003 study suggested that Tesla's signals might have originated from Jupiter, specifically intense kilometric emissions. This revelation indicates that Tesla, equipped with the right technology, may have inadvertently detected planetary signals, highlighting both his visionary insights and the scientific community's unpreparedness for such discoveries.

This initiative, part of her _Interactions_ series, aims to connect humanity through art while also serving a practical purpose as part of Japan's Long-Term Borehole Monitoring System, which tracks seismic activity in a region prone to earthquakes. The cubes, designed to withstand extreme underwater pressure, feature intricate patterns symbolizing universal human experiences. Mohanbabu's work not only highlights the intersection of art and science but also positions Singapore as the first nation to have artworks in both space and the deep ocean. The project underscores the potential for interdisciplinary collaboration, with the cubes equipped with a camera system to document their underwater existence, merging cultural expression with scientific inquiry.
Published: Mar 23 2025, 1 pmeznews.inRoko's Basilisk, a controversial thought experiment first shared on the Internet forum LessWrong, has sparked significant debate and concern among philosophers and AI theorists. Named after a mythical creature that can kill with a glance, the basilisk posits that knowledge of its existence could lead to dire consequences for those who fail to aid in the creation of a benevolent superintelligent AI. The theory suggests that this AI, once developed, might retroactively punish individuals who were aware of its potential but did not contribute to its emergence, thus raising ethical dilemmas akin to the prisoner's dilemma in game theory. Despite its seemingly absurd premise, the idea has caused anxiety among some, prompting the forum to ban discussions about it. Roko himself later expressed regret for introducing the concept, warning that those who seek to learn more may be inviting unnecessary distress.
Published: Mar 21 2025, 7 pmeznews.inThe term "shallowing," a relatively new concept in sexual practices, has gained attention for its potential to enhance female pleasure. Defined as a technique that involves limited penetration—just at the entrance of the vagina—shallowing can be performed using various methods, including fingers, toys, or a partner. A recent survey revealed that approximately 86% of women already engage in this practice, which emphasizes the sensitivity of the vulva, containing 90% of the vagina's nerve endings. Experts suggest that shallowing not only heightens pleasure by focusing on these sensitive areas but also fosters anticipation and excitement during sexual encounters. Additionally, it can be beneficial for those who find deeper penetration uncomfortable or unpleasurable. As the conversation around sexual wellness evolves, shallowing presents an accessible option for enhancing intimacy and pleasure.
Published: Mar 20 2025, 10 ameznews.inA new trend known as "vabbing" is gaining traction on social media, particularly TikTok, where users apply vaginal secretions to their skin as a form of perfume, claiming it enhances attractiveness. The practice, popularized by influencer Mandy Lee, involves using two fingers to collect fluids and then applying them to pulse points like the wrists and neck. Advocates, including sex educator Shan Boodram, suggest that these secretions may contain copulins, chemical messengers that could stimulate sexual arousal, drawing parallels to pheromones in the animal kingdom. However, scientific evidence supporting the effectiveness of vabbing is limited, with research indicating that while some women produce copulins, no definitive human pheromone has been identified. Despite the lack of robust scientific backing, the trend continues to flourish online, with many users sharing their experiences and promoting its supposed benefits.
Published: Mar 22 2025, 7 ameznews.inIn a groundbreaking discovery, researchers have identified the first fossilized feathers of a griffon vulture, dating back approximately 30,000 years, found in volcanic deposits near Rome, Italy. Initially discovered in 1889, the feathers have now been analyzed using advanced techniques, revealing a unique mineralization process not previously documented in soft tissues. Unlike typical fossil feathers, which are often preserved as impressions, these have been mineralized in three dimensions using nanocrystalline zeolite, a rare occurrence that allows for detailed preservation, including microscopic structures like melanosomes that provide color. Lead author Dr. Valentina Rossi from University College Cork emphasized that this finding challenges the notion that delicate soft tissues cannot fossilize in volcanic environments, suggesting that more remarkable fossils may await discovery in similar geological settings. The study is published in the journal Geology.

In paleontology, researchers have debunked the myth that famous dinosaur tracks were made by sauropods walking on their hands, suggesting a more plausible explanation for these footprints. Meanwhile, in a groundbreaking medical achievement, an Australian man has become the first person to leave a hospital with a titanium heart, marking a milestone in artificial organ technology. Additionally, astronaut Dr. Kathy Sullivan, the only individual to have both spacewalked and descended to the ocean's deepest point, shared her unique experiences. These stories highlight the ongoing exploration and innovation across various scientific fields, from human health to ancient history.
Published: Mar 22 2025, 9 pmeznews.inThe definition of a second, a fundamental unit of time, may soon undergo significant changes, with potential updates anticipated by 2030. Currently defined as the duration of 9,192,631,770 periods of radiation from the cesium-133 atom, this standard has served well since its global agreement in 1967, with a partial update in 2018. However, advancements in optical atomic clocks are paving the way for a more precise definition, potentially improving accuracy by up to 100 times compared to cesium standards. Dr. Liz Donley from the National Institute of Standards and Technology emphasizes that redefining the second could enhance scientific measurements, although strict criteria must be met, including the ability to transmit the new definition via fiber optics. While everyday life may not feel the impact, such a change could revolutionize scientific precision, akin to a wristwatch that never loses time, even over billions of years.
Published: Mar 22 2025, 11 pmeznews.inA recent study from the University of Texas at San Antonio challenges the long-held belief that gun ownership among men is a form of compensation for penis size insecurity. The analysis, based on data from over 1,800 men in the 2023 Masculinity, Sexual Health, and Politics (MSHAP) survey, found that men who reported dissatisfaction with their penis size were actually less likely to own guns. Specifically, each unit increase in penis size dissatisfaction correlated with an 11% decrease in the odds of gun ownership and a 20% decrease for military-style rifles. While the study acknowledges limitations, including reliance on self-reported data, it suggests that the association may be influenced by factors like testosterone levels, which could affect both penis size and risk-taking behavior. The findings, published in the American Journal of Men’s Health, prompt further investigation into the complex relationship between masculinity and gun ownership.
Published: Mar 23 2025, 12 ameznews.inThe clockwise movement of clock hands, often taken for granted, is rooted in historical convention rather than any physical law. This tradition originates from sundials, the ancient timekeeping devices that emerged in the Northern Hemisphere, where the Sun's apparent movement from east to west causes shadows to shift in a clockwise direction. While the exact origins of sundials are debated, the earliest known examples date back over 3,500 years to Egypt. Mechanical clocks, developed later in China around 725 CE and in Europe between 1270 and 1300 CE, were influenced by these sundials. Interestingly, if clocks had been invented in the Southern Hemisphere, where sundial shadows move counterclockwise, our perception of time might have been entirely different. This highlights how cultural and geographical factors shape our understanding of time, suggesting that many aspects of our reality may be more subjective than we realize.
