A recent study published in the journal *Sexologies* has identified the missionary position, enhanced by a pillow under the woman's pelvis, as the most effective for heterosexual women seeking orgasm. Conducted by researchers at New H Medical in New York, the study assessed clitoral blood flow across five sexual positions, including variations of face-to-face and kneeling/rear entry. While blood flow increased in all positions except for kneeling/rear entry, the missionary position with a pillow proved most successful. However, the study's limitations are notable; it involved only one heterosexual couple, both medical professionals, which raises questions about the generalizability of the findings. Additionally, the research focused solely on blood flow as an indicator of arousal, rather than directly measuring orgasm. Previous studies have echoed these findings, suggesting a preference for face-to-face positions among larger populations. 
Published: Dec 20 2025, 9 ameznews.inDiscovered just five and a half months ago, interstellar comet 3I/ATLAS has captivated scientists and the public alike, being only the third known interstellar object in our Solar System. Recent studies have highlighted its non-gravitational acceleration, a phenomenon often misinterpreted as evidence of artificial propulsion, such as a spacecraft engine. In reality, this acceleration results from outgassing—when the comet's icy core sublimates as it approaches the Sun, releasing jets of gas and dust that alter its trajectory. Researchers have measured this acceleration at approximately half a micron per second squared, a minor deviation that nonetheless provides insights into the comet's mass, estimated at 44 million metric tons before its solar encounter. This suggests that 3I/ATLAS's nucleus may be smaller than previously thought, measuring around 375 meters (1,230 feet). The findings were published in the journal Research Notes of the American Astronomical Society.
Published: Dec 16 2025, 9 pmeznews.inHumanity's capacity for significant change, both positive and negative, is evident in various contexts, from the climate crisis to the successful eradication of smallpox. A recent study has revealed that our activities, particularly the use of very low frequency (VLF) radio waves, have inadvertently influenced the Earth's radiation belts, known as the Van Allen belts. These belts, discovered in the 1950s, act as a protective shield against harmful cosmic rays and solar winds. Research from NASA's Van Allen Probes, which concluded in 2019, indicates that VLF signals, used in submarine communications, can alter the motion of charged particles in space, effectively creating a barrier that pushes these particles away. This phenomenon has led to the inner edge of the radiation belts shifting outward, suggesting potential applications for VLF technology in protecting Earth from solar storm particles.
Published: Dec 20 2025, 9 pmeznews.inIn mythology, the belly of a whale symbolizes death and rebirth, but in reality, the chances of being swallowed by one are exceedingly slim. The blue whale, the largest animal ever, primarily consumes tiny krill and lacks the physical capacity to swallow a human due to its narrow throat and absence of teeth. Toothed whales, like sperm whales, could theoretically ingest a person, as they prey on giant squid. However, such incidents are rare; the most famous tale involves a whaler named James Bartley, who allegedly survived being swallowed, though this story is widely regarded as a myth. More credible accounts involve near misses, such as lobster diver Michael Packard, who was briefly caught in a humpback whale's mouth in 2021, and kayaker Adrián Simancas, who experienced a similar incident in 2025. These encounters highlight the increasing overlap between human activities and whale habitats, posing risks to both parties.
Published: Dec 17 2025, 7 pmeznews.inIn a remarkable display of tolerance towards nature, Australian resident Jake Gray has welcomed a gigantic huntsman spider, affectionately named Charlotte, into his home for over a year. Sharing his experience on a Facebook spider identification page, Gray explained that the spider has become a part of the family, helping to control pests like cockroaches without the use of toxic chemicals. Despite the initial shock that such a large spider might evoke, Gray reassured his children by naming her and even expressed hopes for her continued growth. While huntsman spiders, known for their speed and size, can appear intimidating, experts note they are generally harmless and prefer to flee rather than bite. With a bite that typically results in mild effects, these spiders serve as natural pest controllers, making them more of a housemate than a threat in Australian homes.
Published: Dec 20 2025, 10 ameznews.inA newly identified species of carnivorous pitcher plant, _Nepenthes megastoma_, has been discovered on Palawan Island in the Philippines, but it faces a dire future with fewer than 50 known specimens remaining. Named for its large mouth, this plant traps insects in its bell-shaped pitcher, breaking them down into a nutrient-rich liquid. Despite its remarkable adaptations for survival in harsh environments, including vertical pollination and water retention, _N. megastoma_ is critically endangered due to human activities such as habitat destruction, poaching, and the impacts of climate change. Researcher John Charles Altomonte highlighted the irony of these resilient plants being threatened by the very species that has encroached upon their habitat. With only about 19 mature clumps and 12 non-flowering plants left, the survival of _N. megastoma_ hangs in the balance, vulnerable to extreme weather events and illegal harvesting. The findings are detailed in the journal Phytotaxa.
Published: Dec 20 2025, 8 ameznews.inRecent research has pinpointed the Zagros Mountains, spanning modern-day Iran, northern Iraq, and southeastern Turkey, as the primary location where Homo sapiens and Neanderthals interbred during the Late Pleistocene. This mountainous region, rich in biodiversity and archaeological sites, provided an ideal environment for both species to coexist and interact. Notable sites, such as the Shanidar Cave, which contains well-preserved Neanderthal remains, support this finding. The Zagros Mountains served as a crucial corridor for human migration out of Africa, facilitating encounters between the two species. Genetic studies reveal that 1 to 4 percent of the genomes of all non-African humans today carry Neanderthal DNA, influencing various traits and health conditions. This research, published in *Scientific Reports*, enhances our understanding of human evolution and the lasting impact of these ancient interspecies interactions.
Published: Dec 18 2025, 2 ameznews.inThe Long-Term Evolution Experiment (LTEE), initiated by Richard Lenski in 1988, has reached a remarkable milestone of 80,000 generations, making it the longest-running evolution study in history. The experiment involves 12 distinct lines of non-pathogenic *Escherichia coli* bacteria, which have been cultivated to observe evolutionary changes over time. Each day, 1% of the bacteria are transferred to a new growth medium, allowing for rapid reproduction and mutation. Key findings include the continuous increase in fitness of the bacteria, even in a stable environment, and the emergence of "hypermutator" strains that exhibit higher mutation rates. The LTEE has produced over 100 research papers, providing insights into natural selection and adaptation, and demonstrating the power of evolution in a controlled laboratory setting. With no plans to conclude the experiment, it continues to yield valuable data on evolutionary processes.
Published: Dec 17 2025, 8 pmeznews.inPet nutrition has become increasingly complex, with concerns over the sourcing of ingredients, such as Antarctic krill, and debates about the safety of raw meat versus the viability of vegan diets for pets. Amidst this, many pet owners are puzzled by their cats and dogs' penchant for eating grass. A 2019 study found that 71% of cats sampled had eaten plants at least six times, with most owners reporting that this behavior was not linked to illness. Instead, it may stem from an evolutionary trait aimed at combating intestinal parasites. Similarly, a 2008 study revealed that 68% of dogs regularly consume plants, with only a small percentage doing so when unwell. While neither species requires grass in their diet, experts suggest that it may provide gastrointestinal benefits or simply be a matter of preference, although pet owners should avoid allowing them to eat chemically treated grass.
Published: Dec 16 2025, 12 ameznews.inTitan, Saturn's largest moon, is unique in the Solar System for its lakes and rain, composed not of water but of methane and hydrocarbons due to its frigid temperatures. While earlier studies suggested the presence of a hidden ocean beneath its icy surface, new research indicates that Titan may instead possess a slushy layer rather than a global ocean. This conclusion stems from detailed modeling that accounts for Titan's deformation under Saturn's gravitational pull, revealing a 15-hour delay in peak deformation and greater energy dissipation than expected for a moon with a deep ocean. The findings suggest that Titan's subsurface environment could be more akin to Arctic sea ice or aquifers, potentially enhancing its habitability. NASA's upcoming Dragonfly mission, set to launch in 2034, aims to further explore Titan's intriguing chemistry and assess its potential for supporting life. The study is published in the journal Nature.
