When pushing one end of a long metal pole, the other end does not move instantly, nor does it do so at the speed of light, as one might intuitively assume. Instead, the movement is dictated by the speed of sound in the material of the pole. Material scientist Brian Haidet explains that when pressure is applied, the first layer of atoms in the pole transmits the force to adjacent layers, creating a wave that travels through the pole at sound speed. This speed varies depending on the material's density and other factors, such as temperature and pressure. In a recent experiment, Haidet demonstrated that the delay in movement at the opposite end of the pole corresponded to the expected speed of sound in steel, highlighting the fascinating complexities of physics that challenge our everyday perceptions of solid objects. 
Published: May 17 2025, 8 pmeznews.inA recent study has shed light on the evolutionary significance of same-sex behavior in animals, challenging the notion that it is an "evolutionary conundrum." Conducted by ecologists from Spain, the research reveals that such behaviors have been documented in over 1,500 species, predominantly among mammals, particularly primates like bonobos, who engage in sexual activities to strengthen social bonds. The study suggests that same-sex interactions help alleviate tension and reduce aggression among competing males, indicating a crucial social function. While same-sex behavior is also observed in fish, amphibians, reptiles, and invertebrates, the reasons behind these actions remain less understood. The authors caution against directly comparing animal same-sex behavior to human sexual orientation, emphasizing that these interactions are often short-term and not indicative of permanent preferences. The findings, published in *Nature Communications*, highlight the need for further research into this underappreciated aspect of animal behavior.
Published: May 17 2025, 10 pmeznews.inA recent analysis of data from NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission has revealed significant differences between the Moon's nearside and far side, extending beyond surface appearances to the interior structure. Researchers found that the nearside is warmer and more geologically active, with a mantle that may be 2-3% "softer" and temperatures 100-200°C higher than the far side, likely due to radioactive materials. This study, led by Dr. Ryan Park, produced the most detailed gravitational map of the Moon to date, highlighting variations in topography, crustal thickness, and heat-producing elements. These findings not only enhance our understanding of the Moon's volcanic history but also have practical implications for future lunar exploration, as the detailed gravity map will aid in developing navigation systems essential for upcoming missions. The research is published in the journal Nature.
Published: May 14 2025, 9 pmeznews.inA family returning from a vacation in Costa Rica has contracted histoplasmosis, a potentially fatal lung infection caused by inhaling fungal spores from bat droppings. The Centers for Disease Control and Prevention (CDC) reported that 12 individuals, including six adults and six children, fell ill after participating in a cave tour linked to a previous outbreak. Symptoms appeared 8 to 19 days post-exposure, with patients experiencing headaches, fever, and respiratory issues. While one adult was hospitalized with possible lung cancer, all patients showed signs of recovery a month later. The CDC is investigating the cases in collaboration with state health departments and has issued a health alert to raise awareness about the risks associated with caving tours. Histoplasma, the fungus responsible for the infection, is prevalent in certain U.S. regions, particularly around the Mississippi and Ohio River valleys, where many are exposed at least once in their lifetime.
Published: May 17 2025, 7 pmeznews.inPaprika, a staple in dishes like paella and even paprika tea, has sparked surprise among many who recently learned that it is not derived from a unique plant but rather from dried sweet and mild peppers. This revelation, shared by Australian food company Nutra Organics on social media, has left some questioning their previous understanding of the spice. Historically, spicier peppers were introduced to Europe by Spanish explorers, leading to the cultivation of milder varieties that produce the sweeter flavor associated with paprika today. The peppers used for paprika are typically longer and thinner than the bell peppers commonly found in the US. While hotter versions of paprika exist, Hungary predominantly uses the sweet variety, which has become a national culinary symbol. In essence, paprika is simply a product of ordinary peppers, dispelling the myth of a distinct paprika plant.
Published: May 17 2025, 6 pmeznews.inDenisova Cave, located in the Altai mountains of southern Russia, is a pivotal archaeological site that has revealed significant insights into human evolution. It is notable for housing remains of _Homo sapiens_, Neanderthals, and the lesser-known Denisovans, a species identified only in 2010 from a finger bone. The cave's layers of sediment chronicle at least four major periods of hominin occupation, beginning with Denisovans around 160,000 years ago and concluding with modern humans approximately 8,000 years ago. Remarkably, a 2018 discovery of a 40,000-year-old bone fragment belonging to a hybrid girl named "Denny," with a Neanderthal mother and Denisovan father, exemplifies the interbreeding among these species. Additionally, artifacts such as a beautifully crafted bracelet suggest that early inhabitants possessed artistic skills. The cave continues to be a treasure trove for researchers, underscoring the complex narrative of human ancestry.
Published: May 17 2025, 6 pmeznews.inPsychologists from Harvard have revealed that asking questions can significantly enhance one's likeability during initial encounters. In a series of studies, participants who engaged in conversations where they asked follow-up questions were rated more favorably by their partners. The research suggests that individuals perceive question-askers as more responsive, which fosters a positive impression. Interestingly, data from a speed-dating study indicated that those who posed more follow-up questions were more likely to secure second dates, highlighting the importance of this conversational technique. Despite these findings, many people underestimate the impact of question-asking on interpersonal relationships. Therefore, in high-pressure social situations, such as meeting new colleagues, focusing on asking questions could be a simple yet effective strategy to appear more likable. The study's findings are detailed in the Journal of Personality and Social Psychology.
Published: May 17 2025, 6 pmeznews.inThe 2-2-2 rule, popularized on Reddit in 2015, offers a structured approach to maintaining relationship satisfaction by encouraging couples to prioritize quality time together. The rule suggests scheduling a date night every two weeks, a weekend getaway every two months, and a week-long vacation every two years. Relationship therapist Dr. Laura Berman endorses this concept, emphasizing the importance of making relationships a priority and investing in them regularly. She proposes a modified version, the 2-6-1 formula, which suggests a date night every two weeks, a getaway every six months, and an annual vacation to foster deeper connections. While the quantity of time spent together is crucial, the quality of interactions—free from distractions like phones—is equally important. Ultimately, the 2-2-2 rule serves as a guide for couples to nurture their relationships, ensuring they remain vibrant and fulfilling over time.
Published: May 17 2025, 7 pmeznews.inDespite extensive exploration of the RMS Titanic wreck since its rediscovery in 1985, no human remains have ever been found, a mystery that continues to intrigue the public. Over 1,500 people perished when the ship sank in 1912, primarily due to immersion hypothermia, yet the absence of skeletons can be attributed to several factors. Many passengers wore lifejackets, which, after death, kept their bodies afloat and likely swept them away in the storm that followed the sinking. Additionally, deep-sea scavengers may have consumed flesh, leaving bones that dissolve at depths below 3,000 feet due to a lack of calcium carbonate in the water. While some speculate that bodies could be preserved in sealed areas of the ship, the likelihood of finding recognizable remains diminishes with each passing year, as noted by deep-sea explorer Robert Ballard.
Published: May 17 2025, 4 pmeznews.inA new trend has emerged on social media, revealing that humans can "gleek," a rather unappealing ability to squirt saliva from beneath the tongue. This phenomenon occurs through Wharton's duct, a small opening that drains saliva from the submandibular glands. While gleeking can happen involuntarily, particularly during yawning, recent TikTok videos have demonstrated how to do it on command. To achieve this, individuals can generate saliva by yawning or consuming sour candy, then position their tongue against the roof of their mouth and push their lower jaw forward. Despite the novelty, experts advise against practicing this skill, as it is generally considered gross and could lead to unintended consequences. As the trend gains traction, many are left wishing they had never learned about this peculiar human talent.
