eznews.inThe enduring myth that microwaves heat food by targeting the "resonant frequency" of water has persisted for nearly 78 years since the first commercial microwave was introduced. In reality, microwaves, produced by a magnetron, heat food through a process known as dielectric heating, where the electric field causes food molecules to rotate and collide, generating heat. While water is a good absorber of microwave energy, the frequency of 2.45 GHz is not specifically tuned to water but is chosen for its effectiveness in heating a variety of substances, including fats and proteins. Additionally, misconceptions about microwaves cooking food from the inside out and ice being unable to heat due to frequency are also debunked. Experts clarify that microwaves heat food primarily from the outside in, with conduction playing a role in cooking the interior. 
Published: Nov 28 2025, 2 ameznews.inA supermassive black hole, designated J2245+3743, has made headlines for producing an unprecedented flare, shining 30 times brighter than any previously recorded event. This active galactic nucleus, located 10 billion light-years away and weighing 500 million times the mass of the Sun, was first observed by the Zwicky Transient Facility (ZTF) in 2018. The flare intensified by a factor of 40 over several months, reaching luminosity equivalent to 10 trillion Suns. Researchers, led by Caltech's Matthew Graham, suspect the phenomenon is a tidal disruption event (TDE), where the black hole tore apart a star at least 30 times the mass of our Sun. Co-author K. E. Saavik Ford emphasized the rarity of such massive stars, suggesting that those within an AGN's disk can grow larger. The findings, published in *Nature Astronomy*, highlight the importance of ZTF in identifying transient cosmic events.
Published: Dec 02 2025, 4 pmeznews.inIn a groundbreaking collaboration, astrophotographer Andrew McCarthy and skydiver Gabriel C. Brown have created a stunning image titled "The Fall of Icarus," capturing Brown's silhouette against the turbulent surface of the Sun. This remarkable photograph, taken in hydrogen alpha light, showcases the Sun's dynamic hydrogen layer and features multiple sunspots. The duo's ambitious project involved meticulous planning and coordination, requiring six attempts to align Brown's jump with the sunspots perfectly. McCarthy described the complex process, which included a three-way call with the paramotor pilot to ensure precise timing. Despite initial setbacks, the final result has been hailed as a masterpiece in astrophotography, raising the bar for future works in the field. Limited edition prints of this extraordinary image are available on McCarthy's website, further highlighting the innovative fusion of skydiving and astrophotography.
Published: Nov 30 2025, 7 pmeznews.inIn the avian world, hummingbirds stand out as the only birds capable of true backward flight, a skill not shared by any other species, including flightless birds like ostriches. Renowned for their vibrant plumage, hummingbirds can flap their wings between 20 to 80 times per second, achieving speeds comparable to fighter jets. Their unique wing structure, which allows for a figure-eight motion, enables them to generate lift on the upstroke, a feat impossible for most birds. This insect-like flight style, as described by biologist Tyson Hedrick, is facilitated by their specialized joints and wing mechanics. Hummingbirds can also navigate through tight spaces by pulling their wings close to their bodies, allowing them to dart through openings with remarkable agility. This combination of speed, maneuverability, and colorful appearance makes hummingbirds a fascinating subject of study in the animal kingdom.
Published: Dec 02 2025, 2 pmeznews.inAcrylamide, a chemical often found in certain foods, has raised health concerns due to its potential dangers. Commonly produced during high-temperature cooking processes, such as frying or baking, acrylamide has been linked to cancer in animal studies, prompting warnings about its presence in food. However, the extent of its risk to human health remains a topic of debate among scientists and health experts. While some studies suggest a correlation between acrylamide consumption and increased cancer risk, others argue that the evidence is inconclusive. As public awareness grows, many are left questioning whether they should be genuinely concerned about acrylamide in their diets. For those seeking more information, resources are available to explore the implications of acrylamide consumption further.
Published: Dec 02 2025, 12 pmeznews.inA recent study has revealed that anacondas, which thrived in what is now Venezuela 12 million years ago, were giants during the Middle to Upper Miocene, yet their size has remarkably remained consistent over millions of years. Researchers analyzed 183 fossilized vertebrae, representing approximately 32 individual snakes, and found that these ancient anacondas measured around 5.3 meters (17 feet) long, similar to modern specimens. This finding contrasts with the trend of many species shrinking in response to environmental changes during that era, which was characterized by warmer and wetter conditions. While other large reptiles like _Purussaurus_ and _Stupendemys_ have gone extinct, anacondas have thrived, likely due to their habitat in swamps and rivers that continue to provide the necessary warmth and food. The study, published in the Journal of Vertebrate Paleontology, highlights the resilience of these snakes, which have maintained their size for millions of years.
Published: Dec 02 2025, 7 ameznews.inIn the ongoing debate over which gender experiences more pain, childbirth and testicular trauma often take center stage. Childbirth is notorious for its excruciating nature, involving hours of intense contractions and the physical challenge of delivering a baby through a narrow birth canal, which can lead to severe complications and long recovery times. Conversely, a kick to the testicles can induce immediate, debilitating pain, often radiating throughout the abdomen, due to the high concentration of nerve endings in the area. While both experiences are intensely painful, the subjective nature of pain makes it difficult to declare a definitive winner. Experts suggest that the evolutionary design of both reproductive organs contributes to their vulnerability and sensitivity, leading to significant discomfort in both scenarios. Ultimately, the conclusion remains ambiguous, with some suggesting a tie, while others humorously note that neither experience is as painful as kidney stones.
Published: Dec 01 2025, 1 pmeznews.inA stalagmite from Hsārok Cave in Kurdistan has unveiled critical insights into climatic conditions from 18,000 to 7,500 years ago, coinciding with the end of the last glacial period and the emergence of agriculture. This discovery is particularly significant as it lies within the Fertile Crescent, a region pivotal to early civilization. The stalagmite's isotopic analysis indicates increased rainfall around 14,560 years ago, followed by a drier period marked by elevated dust levels around 12,700 years ago. These climatic shifts align with patterns observed in Greenland, suggesting a broader global influence. The findings imply that the varied environments of the Zagros Mountains fostered a mobile lifestyle, which later adapted to more stable conditions, facilitating the rise of agriculture. The study, published in the *Proceedings of the National Academy of Sciences*, highlights the interconnectedness of climate and human development during this transformative era.
Published: Dec 02 2025, 5 ameznews.inA recent product review on Sephora for Sol de Janeiro's Delícia Drench™ Body Butter sparked a humorous yet alarming discussion online, as the reviewer claimed the lotion attracted wolf spiders. The now-deleted review suggested that the body butter made the user irresistible to these arachnids, leading to an unusual spike in sightings. However, experts, including Floyd W. Shockley from the Smithsonian, clarified that wolf spiders typically seek shelter indoors during colder months, not due to the lotion. Sol de Janeiro also refuted the claim, stating their product contains none of the chemicals known to attract spiders. Despite the initial buzz, subsequent reviews have reported no increase in spider encounters, reassuring users that the body butter is safe from arachnid attraction. As the internet continues to debate the issue, it seems the only thing the lotion is drawing is attention from curious customers.
Published: Dec 02 2025, 6 ameznews.inChicken has become a staple in the American diet, with the average person consuming around 45 kilograms (100 pounds) annually, according to the National Chicken Council. The domestication of chickens, believed to have originated in the Indus Valley around 2000 BCE, was facilitated by their docile nature and proximity to humans. Initially bred for cockfighting, chickens eventually became a popular food source, particularly during World War II when red meat was scarce. Unlike other birds, such as pigeons and swans, chickens are easier to farm and more palatable, contributing to their dominance in the poultry market. Genetic studies reveal that domestic chickens are hybrids of the red and grey junglefowl, further highlighting their unique suitability for domestication. Ultimately, the combination of their manageable nature and culinary appeal has solidified chickens' place in global cuisine.
