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.inDespite popular belief, crude oil does not originate from dinosaurs but rather from ancient algae and plankton. Geologist Reidar Müller from the University of Oslo clarifies that these microscopic organisms, which lived tens to hundreds of millions of years ago, sank to the ocean floor after dying. Over time, they were buried under layers of sediment, where high pressure and low oxygen conditions transformed them into oil. This process, often referred to as "cooking," is essential for oil formation, and it is unlikely that marine dinosaurs contributed to oil reserves, as their remains would typically be consumed by scavengers before they could be buried. The misconception that oil comes from dinosaurs persists, but the reality is that it is the remnants of tiny marine life that fuel our modern world, despite the environmental challenges posed by fossil fuel consumption.
Published: Jun 01 2025, 8 ameznews.inA recent study suggests that the Kasta tomb, believed to be the burial site of Hephaestion, Alexander the Great's closest companion, may have been intentionally designed to align with the winter solstice. Discovered in 2012 near Amphipolis, Greece, the tomb is the largest of its kind from ancient Macedonia and contains the remains of five individuals. Research led by Demetrius Savvides utilized a 3D model to simulate solar movements, indicating that sunlight fully illuminated the tomb's inner chamber from 10:00 am to 4:00 pm on December 21, potentially symbolizing themes of renewal and life associated with the goddess Cybele. However, historian Juan de Lara from Oxford University has raised concerns about the study's conclusions, noting that the ancient Macedonian lunisolar calendar could mean the solstice date varied annually, suggesting the illumination might be coincidental rather than a deliberate design feature. The findings are published in the Nexus Network Journal.
Published: May 30 2025, 10 pmeznews.inThe tooth-billed pigeon, or manumea, is a critically endangered species in Samoa, often referred to as the "little dodo" due to its rarity and close relation to the extinct bird. Last photographed in 2013, its population has plummeted to fewer than 100 individuals, primarily due to habitat loss, hunting, and predation by invasive species. In a bid to locate these elusive birds, scientists from The Colossal Foundation and the Samoa Conservation Society have developed advanced bioacoustic technology capable of detecting their unique calls with 95% accuracy. This innovative approach utilizes machine learning algorithms to classify bird calls, even for species with minimal recordings. The collaboration aims to locate the pigeons, capture live specimens for biobanking, and potentially establish a captive breeding program to prevent extinction. The initiative represents a significant step in conservation efforts for this national treasure, with hopes of reviving its dwindling population.
Published: May 31 2025, 2 pmeznews.inThe Oldowan stones, dating back 2-3 million years, are the earliest known examples of stone tools, marking a pivotal moment in human evolution by showcasing the first evidence of cultural behavior. Discovered initially at Olduvai Gorge in Tanzania, these tools are characterized by hand-held cores with sharp edges, suitable for cutting and scraping. Despite extensive research, the identity of their creators remains elusive, with various hominin species, including _Homo habilis_ and _Paranthropus boisei_, being considered potential manufacturers. Recent studies suggest that the Oldowan technology may have emerged around 3.25 million years ago and persisted until 1.2 million years ago, indicating a complex interplay of multiple hominin species in tool-making. The research highlights that no single species is solely responsible for the Oldowan tools, suggesting a possible cultural exchange between early _Homo_ and _P. boisei_. The findings are detailed in the Journal of Anthropological Archaeology.
Published: May 31 2025, 6 pmeznews.inWater fluoridation is a contentious issue in the United States, with recent discussions around potential bans gaining momentum. Introduced in Michigan in 1945, fluoride in public drinking water has been credited with improving oral health but has faced significant opposition due to concerns over its neurotoxic effects. U.S. Health Secretary Robert F. Kennedy Jr. has suggested rescinding CDC recommendations for fluoridation, while the EPA is reviewing its health risks. A study by Harvard researchers predicts that halting fluoridation could lead to a 7.5% increase in dental caries over five years, resulting in 25.4 million additional cases and an economic burden of $9.8 billion. The researchers emphasize that, despite fears of toxicity, the benefits of fluoridation at safe levels far outweigh the risks, particularly for children, underscoring the importance of maintaining this public health measure. The findings are published in JAMA Health Forum.
Published: Jun 01 2025, 3 ameznews.inA newly discovered Neanderthal fingerprint, found on a pebble at the San Lázaro rock shelter in central Spain, may have been left by a prehistoric artist painting a face using red ocher. Dated to around 43,000 years ago, the pebble is associated with Neanderthal tools and suggests advanced cognitive abilities, including the capacity for abstraction and pareidolia—the tendency to see faces in inanimate objects. Researchers note that the ocher dot appears deliberately applied, indicating symbolic rather than utilitarian use. The pebble's features, combined with natural depressions, could resemble a human face, leading to speculation about the intentions of its creator. While the study does not definitively conclude the nature of the red dot, it raises the possibility that both Neanderthals and early modern humans shared similar interpretative skills. The findings are detailed in the journal *Archaeological and Anthropological Sciences*.
Published: May 31 2025, 4 pmeznews.inSir David Attenborough's latest documentary, _OCEAN_, features groundbreaking footage from the perspective of a bottom trawler, revealing the devastating impact of this fishing method on marine ecosystems. The film captures fish, cephalopods, and rays fleeing as the trawler's net devastates the seabed, a sight that has deeply affected marine conservationists like Enric Sala, who highlights that bottom trawling produces carbon emissions comparable to global aviation. Research indicates that this practice can strip up to 41% of seabed fauna, with recovery taking over six years. Toby Nowlan, the film's director, compares the destruction to bulldozing ancient woodlands, emphasizing the urgent need for change. As _OCEAN_ airs ahead of the 2025 UN Ocean Conference, it aims to raise awareness and prompt action to protect 30% of the ocean by 2030, challenging viewers to confront the hidden devastation beneath the waves.
Published: May 29 2025, 5 pmeznews.inFor the first time, researchers have captured a photograph of a living Upemba lechwe (_Kobus anselli_), a critically endangered antelope species, during an aerial survey of the Kamalondo Depression in the Democratic Republic of the Congo, its sole habitat. Lead author Manuel Weber from Upemba National Park described the fleeting moment when he managed to photograph the animal, marking the first published image of the species since its identification in 2005. The recent survey, the first in over 50 years, revealed a stark decline in numbers, estimating fewer than 100 individuals remain, a significant drop from earlier estimates of 5,000 to 20,000 in the 1970s. Poaching has been a major factor in this decline. Weber and his team are calling for immediate protective measures to prevent the species from vanishing entirely, hoping the photograph will galvanize conservation efforts. The findings are published in the African Journal of Ecology.
Published: May 29 2025, 4 pmeznews.inIstanbul-based illustrator and paleoartist C. M. Kosemen has created a striking series of illustrations that re-imagine contemporary animals as if they were depicted solely from their skeletal remains, much like how dinosaurs are often portrayed. These artworks reveal a terrifying and often inaccurate vision of familiar creatures, such as elephants and baboons, which appear alarmingly skeletal due to the guesswork involved in estimating their soft tissue. Kosemen's work highlights the challenges of paleoart, where the absence of living references can lead to distorted representations, as seen in the historical misinterpretation of the woolly rhinoceros as a unicorn in the 17th century. This exploration raises questions about the reliability of fossilized bones as a foundation for understanding extinct species and underscores the evolving nature of scientific reconstructions, as exemplified by the changing depictions of velociraptors over the years.

Published: May 31 2025, 11 pmeznews.inFour critically endangered female eastern lowland gorillas—Mapendo, Ndjingala, Isangi, and Lulingu—have been successfully reintroduced to their natural habitat in Virunga National Park, eastern Democratic Republic of the Congo. Rescued from poachers and rehabilitated at the Gorilla Rehabilitation and Conservation Education Center (GRACE), the gorillas were airlifted to Mt. Tshiaberimu, a site steeped in local lore. This rewilding initiative, supported by over 400 contributors, aims to bolster the region's dwindling gorilla population, which has fallen to just eight individuals. Following their release, the gorillas quickly adapted, interacting with a wild silverback named Mwasa and foraging for new food sources. While the initial signs of success are promising, conservationists acknowledge the ongoing challenges ahead. Experts emphasize the importance of community involvement in conservation efforts, highlighting this project as a potential model for future rewilding initiatives.
