A recent study published in BJU International has revealed a significant increase in the depiction of penis size in art over the past seven centuries, particularly from the 19th century onwards. Researchers analyzed 232 paintings of nude males, focusing on the penis-to-ear and penis-to-nose ratios to assess changes in perceived ideal size. They found that while penis sizes were relatively small in the 15th and 16th centuries, the average ratio rose dramatically to 1.5761 in the 21st century. The study suggests that the rise in perceived size may be influenced by the internet and pornography, which often associate larger penises with masculinity and sexual satisfaction. This shift could contribute to body image issues among men, as many tend to overestimate average sizes and seek potentially harmful enhancements. The study acknowledges its limitations, including a European bias in the selected artworks. 
Published: Nov 22 2024, 2 ameznews.inA study led by the University of Southern Mississippi has revealed that the 2010 Deepwater Horizon oil spill is accelerating the corrosion of historical shipwrecks, including the German U-boat U-166, which sank during World War II. The spill released over 4.9 million barrels of oil into the Gulf of Mexico, causing extensive environmental damage. Researchers found that the influx of crude oil has fueled the growth of anaerobic bacteria on the seafloor, which thrive on the oil's carbon and sulfur. This bacterial boom produces a corrosive biofilm that significantly degrades metal structures. Experiments showed that carbon steel disks placed near the wrecks experienced greater corrosion compared to those in cleaner waters. The study highlights the need for further research into the interactions between oil spills, biofilms, and marine metal degradation, emphasizing the cultural significance of the U-166 and the broader implications of the ongoing environmental disaster.
Published: Nov 23 2024, 12 pmeznews.inGasoline and diesel fuel, both derived from crude oil, serve distinct purposes in the automotive industry due to their differing chemical properties and engine requirements. Gasoline powers light-duty vehicles like cars and pickup trucks, utilizing spark plugs to ignite a fuel-air mixture, while diesel fuels heavy-duty vehicles such as buses and trucks, igniting through high compression without a spark. Diesel engines are more efficient and durable, making them ideal for long-haul transport, despite being noisier and producing more harmful particulate pollution. Conversely, gasoline engines are preferred for personal vehicles due to their quieter operation and lower initial costs. As the automotive landscape evolves, hybrid and electric vehicles are emerging as cleaner alternatives, promising reduced emissions and lower maintenance costs, although gasoline and diesel vehicles will continue to be prevalent for the foreseeable future.

James Cameron, who has visited the site 33 times, noted the absence of remains, despite finding clothing and shoes that suggest bodies were once present. Several factors contribute to this mystery: many victims' lifejackets kept their bodies buoyant, leading to their swift dispersal by storms and ocean currents. Additionally, deep-sea scavengers likely consumed flesh, leaving bones that dissolve below the calcium carbonate compensation depth, which is over 3,000 feet deep. While some speculate that sealed areas of the ship, like the engine room, may still contain preserved remains, the likelihood of discovering recognizable bodies diminishes as time passes, leaving the fate of over 1,500 victims shrouded in uncertainty.
Published: Nov 21 2024, 10 ameznews.inThe configuration of standard six-sided dice, where opposite faces sum to seven, has a long and intriguing history. This design, which pairs one with six, two with five, and three with four, became prevalent in the Egyptian New Kingdom around the 16th century BC and was adopted by the Greeks in the 1st millennium BCE. While earlier dice often featured consecutive values on opposite sides, the "sevens" arrangement likely emerged from aesthetic preference rather than mathematical necessity. It allows for symmetrical pairing and has significant cultural resonance, as the Greeks valued harmonic combinations. By the end of the Middle Ages, laws were enacted to standardize this configuration, solidifying its universal acceptance. Ultimately, the enduring popularity of this design can be attributed to tradition, as it became a rule of play that, if violated, was seen as undermining the integrity of the game.
Published: Nov 23 2024, 3 ameznews.inRobert Wadlow, known as the "Alton Giant," holds the record as the tallest person in history, reaching an astonishing height of 2.72 meters (8 feet, 11 inches) before his untimely death at age 22. Born in February 1918 in Alton, Illinois, to average-sized parents, Wadlow's extraordinary growth was attributed to hyperplasia of his pituitary gland, leading to excessive production of growth hormones. By age five, he was already 1.63 meters tall, and he continued to grow throughout his life, requiring custom-made clothing and shoes, including size 17.5 footwear. Wadlow gained fame while touring with the Ringling Brothers Circus and appeared in a documentary about his life. Tragically, he passed away in July 1940 due to an infected sore from a leg brace, leaving behind a legacy commemorated by a lifesize statue near the Alton Museum of History and Art.
Published: Nov 23 2024, 6 ameznews.inWhen you close your eyes, you may notice swirling patterns and flashes of light, known as "phosphenes." These visual sensations occur due to the normal functioning of the eyes, which continue to generate weak internal signals in the absence of light. According to Katrina Schmid, an Associate Professor at Queensland University of Technology, these signals are interpreted by the brain as light, creating the illusion of colors and patterns. While phosphenes are typically harmless, they can also indicate underlying retinal issues or neurological conditions if they become more pronounced or persistent. In such cases, consulting a medical professional is advisable. The phenomenon can also be triggered by applying pressure to the eyeball, although this should be avoided. Overall, while phosphenes are a common experience, changes in their nature warrant attention.

Published: Nov 23 2024, 1 ameznews.inResearchers have finally unraveled the mystery behind certain metal alloys, specifically Invar, which do not expand when heated, a phenomenon first noted by Charles-Edouard Guillaume in 1895. This unique behavior occurs only in specific ratios of iron and nickel, such as 13 iron atoms to 7 nickel atoms, and is attributed to the interplay between magnetism and atomic vibrations. A team led by Caltech's Stefan Lohaus discovered that magnetic effects organize the atoms in a way that counteracts the typical expansion caused by increased heat. Their findings suggest that as temperature rises, some electrons flip their spin states, allowing atoms to come closer together, balancing the vibrations that would normally push them apart. This research, published in *Nature Physics*, could have significant implications for manufacturing precise instruments and building resilient infrastructure, particularly in the face of climate-related challenges.
Published: Nov 23 2024, 4 ameznews.inFerdinand Magellan is widely recognized for leading the first successful circumnavigation of the globe from 1519 to 1522, yet his legacy may be contested by an unsung figure, Enrique of Malacca. An enslaved man of Southeast Asian origin, Enrique accompanied Magellan on his expedition and is believed to have effectively circumnavigated the globe himself, having traveled from his homeland to Europe and back to Southeast Asia. Magellan's journey, which included navigating the treacherous Strait of Magellan and enduring severe hardships in the Pacific, ultimately ended in tragedy when he was killed in the Philippines in 1521. His crew, led by Juan Sebastián Elcano, completed the voyage and returned to Spain in 1522. This narrative not only challenges the traditional view of exploration but also highlights the often-overlooked contributions of non-European individuals in shaping history.
