A comprehensive study analyzing penis sizes from 1942 to 2021 has revealed a notable increase in average erect penis length over the past three decades, while flaccid lengths remained unchanged. The meta-analysis, which included data from 55,761 males globally, found that erect length rose by 24 percent, from 12.3 centimeters (4.8 inches) to 15.2 centimeters (6 inches). Lead researcher Michael Eisenberg from Stanford Medicine suggested that this increase may be linked to environmental factors, such as chemical exposure that disrupts hormonal systems, rather than a decline in reproductive health, which has been observed in other studies. The research, published in the World Journal of Men's Health, emphasizes the need for further investigation into these findings, as the rapid change could indicate significant underlying shifts in male physiology. The study's methodology focused on measurements taken by investigators, excluding self-reported data to ensure accuracy. 
Published: Apr 14 2025, 6 pmeznews.inRecent observations from the James Webb Space Telescope (JWST) have provided further insights into the enigmatic nature of dark matter and its role in the universe. Regular matter constitutes only about 5% of the universe's total content, with approximately 70% attributed to dark energy and the remainder to dark matter, which interacts only through gravity. The Bullet Cluster, a collision of two galaxy clusters, serves as a key example, revealing a separation between the hot gas observed in X-rays and the distribution of dark matter inferred through gravitational lensing. Researchers, including Kyle Finner and James Jee, emphasize that these findings support the existence of dark matter, as it can explain specific cosmic phenomena that alternative theories, like Modified Newtonian Dynamics (MOND), cannot. The study, published in The Astrophysical Journal Letters, suggests a more complex understanding of the Bullet Cluster's dynamics than previously recognized, highlighting the ongoing quest to unravel the universe's mysteries.
Published: Jul 02 2025, 5 pmeznews.inA new study led by Dr. Marina Weiler at the University of Virginia has revealed common factors among individuals who have experienced out-of-body experiences (OBEs), a phenomenon where people perceive the world from outside their bodies. Surveys indicate that 10 to 20 percent of the population has encountered OBEs, which can occur during moments of tranquility or extreme stress. The research, involving 545 adults, found that 80 percent of OBE experiences were spontaneous, with others linked to meditation or psychoactive substances. Notably, those who reported OBEs exhibited higher levels of mental health issues, including depression and anxiety, and were more prone to dissociation. The study suggests that OBEs may serve as a coping mechanism for past trauma rather than indicating mental illness. The authors call for a more nuanced understanding of OBEs within mental health contexts, emphasizing the need for further research into their underlying mechanisms.
Published: Jul 01 2025, 7 ameznews.inA groundbreaking discovery of wooden tools, estimated to be around 300,000 years old, has been made at the Gantangqing archaeological site in southwest China, challenging previous assumptions about the technological capabilities of early hominids in East Asia. The collection, which includes 35 artifacts designed for harvesting vegetation, indicates that prehistoric communities relied heavily on plant-based diets in subtropical environments, contrasting with the hunting-focused lifestyles observed in northern temperate regions. Professor Bo Li, the study's author, suggests that these tools, primarily made from pine, were likely crafted by Denisovans, a sophisticated hominin group co-existing with Neanderthals. The findings highlight the strategic use of lakeshore resources and the importance of plant foods, with potential harvesting of kiwis, nuts, and tubers. This research, published in the journal *Science*, significantly enhances our understanding of early human subsistence and technological innovation in East Asia.
Published: Jul 04 2025, 1 ameznews.inNASA's latest simulations indicate that asteroid 2024 YR4, discovered in December 2024, has a 4.3% chance of impacting the Moon on December 22, 2032, a significant increase from earlier estimates. Initially, the asteroid posed a 1% risk of colliding with Earth, which has since dropped to 0.004%. If it strikes the Moon, the event could be spectacular, potentially creating a crater about 1 kilometer wide and ejecting up to 108 kilograms of lunar material, which could lead to meteor showers visible from Earth. However, this debris may also pose risks to satellites in orbit and lunar operations, with the potential for increased meteoroid impacts. While the odds of a lunar impact remain low, astronomers are closely monitoring the asteroid, with further observations expected in 2028 as it approaches Earth again. The findings are detailed in a paper submitted to the American Astronomical Society.
Published: Jul 03 2025, 10 pmeznews.inHumans have maintained a continuous presence in space for nearly 25 years aboard the International Space Station (ISS), which began operations in 2000. However, as the ISS nears the end of its operational life, set for 2030, NASA and other space agencies are preparing for a transition to commercial space stations. The ISS, initially launched in 1998, will exceed its planned lifespan due to the inability to repair its primary structure. NASA plans to shift operations to privately-owned destinations in low Earth orbit, with the upcoming Vast’s Haven-1 space station expected to launch in May 2026. This smaller station will host astronauts for short stays, focusing on safety and comfort, including innovative inflatable beds. Other companies, like Axiom, are also developing their own stations, ensuring that humanity's presence in space continues beyond the ISS's decommissioning.
Published: Jul 02 2025, 1 pmeznews.inThe Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current system that regulates climate by transporting warm water from the tropics to the North Atlantic, is showing signs of weakening, raising concerns about its potential collapse. Recent research from the University of California, Riverside, links a peculiar cold water "hole" near Greenland to this slowdown, attributed to human-induced climate change factors like altered rainfall and Greenland Ice Sheet melt. While some studies warn of a catastrophic collapse, others suggest that the AMOC may only experience a limited decline over the 21st century, with less severe impacts than previously feared. Additionally, the AMOC's slowdown is affecting global weather patterns, including increased dry season rainfall in the Southern Amazon. These findings highlight the urgent need for further research to understand the AMOC's future and its implications for ecosystems and societies worldwide.
Published: Jul 03 2025, 7 pmeznews.inOn July 1, the ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope announced the discovery of an interstellar object, now named 3I/ATLAS, which has been confirmed as a comet. This celestial body is moving at an impressive speed of approximately 58 kilometers (36 miles) per second, nearly double that of its predecessors, ‘Oumuamua and Comet 2I/Borisov. Initial observations suggest that 3I/ATLAS may be significantly larger than these earlier visitors, with estimates placing its size at around 20 kilometers, although further observations are needed to confirm this. Astronomers worldwide are currently studying its properties, and the comet is expected to remain visible from Earth until September before passing behind the Sun, re-emerging in December. The discovery has sparked excitement in the scientific community, with archival observations dating back to June 14 aiding in refining its characteristics. 3I/ATLAS will come closest to the Sun on October 30, 2025, at a distance of 210 million kilometers (130 million miles).
Published: Jul 03 2025, 8 pmeznews.inA new hypothesis has emerged regarding the proportions of Leonardo da Vinci's iconic Vitruvian Man, suggesting that the answer lies within human anatomy itself. Rory Mac Sweeney, a dentist, posits that da Vinci's design was influenced by an equilateral triangle, a concept familiar in dental anatomy, which connects the jaw's condyles to the midpoint of the lower incisors. This triangle, he argues, aligns with the geometric relationships described in da Vinci's own notes, where he indicated that the navel serves as the center for the figure's proportions. Mac Sweeney's analysis reveals that the ratio of the square's side to the circle's radius in the drawing is approximately 1.64, closely mirroring ratios found in human cranial architecture. This insight underscores da Vinci's profound understanding of the interplay between mathematics and the human form, reinforcing his legacy as a pioneer in both art and science.
Published: Jul 03 2025, 5 pmeznews.inYoung people today are drinking less alcohol than previous generations, including millennials, Gen X, and baby boomers, prompting researchers from Australia and Sweden to explore the reasons behind this trend. In a special issue of the journal *Drug and Alcohol Review*, they highlight that while Gen Z is often labeled as the "sober-curious generation," their relationship with alcohol is complex. A 2023 Mintel study indicates that many Gen Zers view alcohol as an occasional treat rather than a regular indulgence. The decline in drinking appears to be more pronounced among boys, narrowing the gender gap in consumption. Factors influencing this shift may include a growing preference for cannabis, concerns about the emotional effects of drinking, and a desire for healthier alternatives. However, research on the health implications of reduced alcohol consumption remains mixed, necessitating further investigation into the evolving dynamics of youth drinking and its associated risks.
Published: Jul 03 2025, 6 pmeznews.inIn 1963, a man in Turkey's Nevşehir Province accidentally discovered the ancient underground city of Derinkuyu while breaking through a basement wall. This remarkable site, which extends up to 18 stories deep, features chapels, schools, and stables, and is believed to have been constructed as early as the 8th–7th centuries BCE. Archaeologists estimate it could accommodate around 20,000 people, with its peak during the Byzantine period, when it evolved into a complex network of tunnels and chambers covering 445 square kilometers. Initially used for food storage, the city served as a refuge for various groups, including early Christians fleeing Roman persecution and Muslims during the Arab-Byzantine wars. Its defensive design included narrow passageways and rolling stone doors, allowing inhabitants to thwart invaders effectively. Derinkuyu remains a testament to the ingenuity of its builders and the historical need for shelter from conflict.
