In a surprising turn of events, researchers at the Australian Square Kilometre Array Pathfinder detected a mysterious radio pulse on June 13, 2024, believed to originate from the long-defunct NASA Relay 2 satellite, which ceased operations in 1965. The signal, lasting less than 30 nanoseconds, was traced to orbit rather than deep space, raising questions about the satellite's status. Scientists, including Clancy James from Curtin University, suggest that the pulse may result from an electrostatic discharge or a micrometeoroid impact, both of which could provide insights into protecting spacecraft from similar occurrences. While the phenomenon is intriguing, it is not unprecedented; there have been instances of "zombie satellites" reactivating after years of dormancy, such as Galaxy 15 and AMSAT-OSCAR 7. A paper detailing this discovery is set for publication in The Astrophysical Journal. 
Published: Jun 21 2025, 3 ameznews.inMany people find themselves waking up at 3 AM, a phenomenon that is often linked to the natural sleep cycle. During a typical night, individuals experience several sleep cycles, transitioning from light sleep to deeper stages and then to REM sleep, which can lead to brief awakenings. While waking up is normal, stress and anxiety can exacerbate these moments, turning them into prolonged periods of wakefulness filled with worry. Psychologist Greg Murray explains that the inability to address problems at night can lead to irrational thoughts, making issues seem more daunting. To combat this, he suggests mindfulness meditation to help calm the mind, or reading a book to distract from anxious thoughts. Ultimately, while waking at this hour is common, managing stress can help individuals return to sleep more easily.
Published: Jun 21 2025, 7 pmeznews.inMathematicians have long grappled with the elusive nature of prime numbers, which are defined as integers greater than one that have no divisors other than one and themselves. The ancient Greek mathematician Eratosthenes devised a "sieve" method to identify primes, a technique that remains effective today. However, a recent breakthrough by a team of mathematicians, including Ken Ono from the University of Virginia, has revealed a surprising connection between prime numbers and integer partitions, a concept from combinatorics. Their research suggests that integer partitions can detect primes in infinitely many ways, offering new insights into these fundamental numbers. This discovery, which earned Ono recognition as a finalist for the 2025 Cozzarelli Prize, could pave the way for advancements in number theory and cryptography, although experts assure that current security measures remain intact. The findings were published in the Proceedings of the National Academy of Sciences.
Published: Jun 21 2025, 3 pmeznews.inAs summer temperatures soar, many are seeking ways to stay cool without air conditioning. Experts suggest several effective strategies to beat the heat. First, keeping blinds and curtains closed can prevent up to 30% of heat from entering through windows, with blackout curtains offering additional benefits. Creating airflow by strategically opening and closing doors can help maintain cooler temperatures in occupied rooms. Enhancing fans with bowls of ice can circulate cooler air, while a fan network can optimize airflow throughout the house. Additionally, turning off appliances and lights reduces heat generation. Opening windows at night to let in cooler air and using ceiling fans in a counter-clockwise direction can further aid in cooling. Staying hydrated, using water sprays, and opting for breathable cotton or silk sheets can also provide relief. Finally, incorporating houseplants that absorb humidity can contribute to a cooler indoor environment.
Published: Jun 21 2025, 5 pmeznews.inScientists are calling for an investigation into the intriguing claim that some individuals can detect the smell of ants while others cannot. This debate has gained traction on social media, particularly TikTok, where users have shared varied descriptions of the scent, ranging from "spicy" to "chemical" and "earthy." A recent unscientific poll on X, formerly Twitter, revealed that about 20% of over 700 respondents reported being able to smell ants, while 80% expressed confusion over the phenomenon. Research by entomologists, including a 2015 study on the odorous house ant (_Tapinoma sessile_), found that many people likened the scent to blue cheese, attributed to the presence of methyl ketones. While some speculate that genetic factors may influence scent detection, evidence remains limited. The variability in ant species and their odors could also play a role, leaving the mystery of ant scent perception unresolved.
Published: Jun 21 2025, 9 ameznews.inResearchers have uncovered what may be one of the largest known lekking arenas of dinosaurs, with 35 ancient mating display scrape sites identified in Colorado's Dinosaur Ridge. These 100-million-year-old trace fossils, known as _Ostendichnus_, suggest that dinosaurs engaged in elaborate courtship behaviors similar to modern birds, where males perform to attract females. The study, led by Dr. Caldwell Buntin, utilized high-resolution drone imagery to analyze the sites, revealing that 25 of the scrapes are reliable indicators of mating displays. This discovery significantly expands our understanding of dinosaur social interactions, indicating that such behaviors were widespread rather than isolated. The findings also suggest that these display areas may have later served as nesting sites, paralleling behaviors observed in contemporary avian species. The public can view these fascinating sites along an interpretive trail at Dinosaur Ridge, making this ancient arena accessible for exploration. The study is published in *Cretaceous Research*.
Published: Jun 21 2025, 5 ameznews.inUpon returning from holiday, the excitement of unpacking can lead to unwanted stowaways in your luggage, particularly bedbugs. These pests, primarily _Cimex lectularius_ and _C. hemipterus_, thrive in high-traffic areas like hotels and hostels, where they can easily hitch a ride home with unsuspecting travelers. Signs of a bedbug infestation include bite marks resembling a "breakfast, lunch, and dinner" pattern on the skin. To mitigate the risk, experts recommend storing luggage in the bathtub during your stay, as the moisture deters these bloodsuckers. If you suspect bedbugs have made their way into your suitcase, keeping your clothes in a hot dryer cycle can effectively eliminate them and their eggs. While the thrill of travel is enticing, ensuring your home remains pest-free is paramount.
Published: Jun 21 2025, 12 pmeznews.inResearchers have identified four distinct species of king cobra, previously classified as a single species since 1836. The study, led by P. Gowri Shankar, revealed significant genetic and morphological differences among populations across Asia, including variations in scale banding patterns. The newly recognized species are the Northern king cobra (_Ophiophagus hannah_), Sunda king cobra (_Ophiophagus bungarus_), Western Ghats king cobra (_Ophiophagus kaalinga_), and Luzon king cobra (_Ophiophagus salvatana_). This classification is crucial for conservation efforts, as the smaller ranges of _O. kaalinga_ and _O. salvatana_ may be particularly vulnerable to climate change and habitat destruction. The findings also highlight the need for tailored antivenoms, as the current single antivenom may not effectively address the venom variations among the new species. The study underscores the importance of recognizing biodiversity for effective conservation policies and actions.
Published: Jun 21 2025, 12 pmeznews.inWhile Queen Elizabeth II's 70-year reign and Louis XIV's 72 years are notable, the title of the longest-reigning monarch in history belongs to Ancient Egypt's Pepi II, who ascended the throne at just six years old around 2281 BCE. His reign, lasting an astonishing 94 years according to the ancient historian Manetho, is shrouded in controversy due to the lack of contemporary records and the fact that Manetho wrote his account approximately 2,000 years later. The Papyrus of Kings, which lists Egyptian rulers, supports this claim but was composed during the reign of Ramesses II, raising further doubts about its accuracy. Historians question the legitimacy of Pepi II's reign length, noting that he appears to have ceased being mentioned after his 31st count, suggesting he may not have lived to the age of 100. Nonetheless, Guinness World Records recognizes Pepi II as the longest-serving monarch, a title that remains contested.
Published: Jun 21 2025, 1 pmeznews.inHave you ever felt a strange sensation when touching your belly button? This peculiar feeling, which can trigger a tingling in the groin or an urge to urinate, has a scientific explanation. The belly button, or umbilicus, is connected to nerve fibers that relay information to the spinal cord, including signals from the bladder and urethra. According to Dr. Christopher Hollingsworth from NYC Surgical Associates, stimulating the belly button can trick the brain into interpreting these signals, mimicking the sensation of needing to pee. However, this odd feeling only occurs when pressure is applied deeply into the belly button, as the internal lining, known as the parietal peritoneum, is highly sensitive. A gentle touch won't elicit the same response, but a deeper poke can lead to this unexpected and curious sensation.
