eznews.inThe oldest known written text, the Kish tablet, dates back to around 3,500 BCE and was discovered in the ancient Sumerian city of Kish, now in modern-day Iraq. This limestone tablet features purely pictographic writing, representing a transitional phase between proto-writing and the more advanced cuneiform script. Cuneiform, which means "wedge-shaped," became the dominant writing system in the ancient Middle East, utilized by various cultures, including the Assyrians and Babylonians, for approximately 3,000 years. It involved pressing reed styluses into clay to create wedge-shaped marks that represented spoken syllables. The significance of cuneiform lies in its ability to convey complex ideas and its historical impact, producing hundreds of thousands of inscribed objects. Rediscovered in the early 19th century, these tablets have since been the focus of extensive archaeological and linguistic research, revealing insights into early human communication and civilization.

Published: Dec 13 2025, 4 ameznews.inPizzlies, or grolar bears, are hybrid offspring of grizzly (_Ursus arctos horribilis_) and polar bears (_Ursus maritimus_), emerging as a concerning indicator of climate change's impact on Arctic ecosystems. While rare, sightings of these hybrids have increased, prompting scientists to study their potential rise due to habitat overlap caused by warming temperatures. The first confirmed pizzly was shot in 2006 in Canada, and subsequent research has identified second-generation hybrids, highlighting a complex interbreeding dynamic. As polar bears migrate southward and grizzlies move north, their interactions are becoming more frequent, leading to both competition and mating. Experts warn that continued hybridization could threaten the polar bear population, potentially leading to their extinction as they are absorbed into the grizzly gene pool. This phenomenon underscores the drastic changes occurring in the Arctic, raising alarms about the future of these iconic species.
Published: Dec 13 2025, 5 ameznews.inWhile humans adhere to a strict dental hygiene routine, the dental health of wild animals, such as bonobos, raises intriguing questions about their lack of tooth brushing. Peter Kertesz, a dental consultant for ZSL London Zoo and various wildlife facilities, explains that animals often do not require dental care like humans due to their natural diets, which are typically free from refined carbohydrates that contribute to tooth decay. Kertesz, who has treated a wide range of species from elephants to dolphins, notes that trauma is a more common dental issue among animals than decay. In controlled environments like zoos, animals live longer and receive better nutrition, leading to unique dental challenges, particularly in older populations. Ultimately, Kertesz emphasizes that a diet closely aligned with an animal's natural habitat is crucial for maintaining their dental health, as poor diet can lead to severe health repercussions.
Published: Dec 13 2025, 3 ameznews.inResearch from the University of East Anglia reveals that polar bears are genetically adapting to climate change, though this development raises concerns about their survival. Analyzing blood samples from 17 polar bears in Greenland, scientists found significant differences in gene activity between those in warmer southeastern regions and their colder northeastern counterparts. The study highlighted changes linked to heat stress, aging, and metabolism in the warmer population, suggesting a rapid genetic response to environmental challenges. Dr. Alice Godden, the lead researcher, emphasized that while this adaptation offers a glimmer of hope, it does not mitigate the species' risk of extinction. The findings underscore the urgent need for conservation efforts and global action to reduce carbon emissions. Additionally, the study points to broader trends, such as polar bears moving inland and interbreeding with grizzlies, further complicating their future. The research is published in the journal Mobile DNA.
Published: Dec 13 2025, 1 ameznews.inIn a regrettable incident in 1964, graduate student Donald R. Currey inadvertently felled Prometheus, a bristlecone pine that would later be confirmed as the oldest tree ever dated, estimated at 4,900 years old. Currey, intrigued by the tree's potential for his research on glacial features in Great Basin National Park, sought to extract core samples to analyze its growth rings. However, when traditional coring methods failed, he obtained permission from the US Forest Service to cut down the tree. It was only after counting the rings from the cross-section that Currey realized the monumental age of Prometheus, which had been alive since before the rise of ancient civilizations. The tree's demise left only a stump at its original site, while a slab of Prometheus can be viewed at the Great Basin Visitor Center, serving as a poignant reminder of the loss of this ancient natural wonder.
Published: Dec 12 2025, 11 pmeznews.inRecent discussions in the scientific community have highlighted the fascinating phenomenon of tails in celestial bodies, particularly in relation to the interstellar comet 3I/ATLAS, which has developed both a tail and a rare anti-tail during its passage through our Solar System. However, comets are not alone in this characteristic; Mercury also possesses a sodium tail, created by its thin atmosphere being influenced by solar radiation. Interestingly, Earth has its own tail, known as the "magnetotail," which extends at least 2 million kilometers into space. This tail is formed by the Earth's magnetosphere, which traps plasma and is shaped by the solar wind. While the magnetotail is a permanent feature, its size and shape can fluctuate, especially during solar events like coronal mass ejections. Despite extensive exploration by spacecraft, many mysteries about Earth's magnetotail remain, due to its vast and complex nature.
Published: Dec 09 2025, 8 pmeznews.inSheep possess a unique rectangular pupil shape, unlike the round pupils found in humans, which plays a crucial role in their survival as prey animals. This distinctive feature, shared with other ruminants like goats and deer, enhances their panoramic vision, allowing them to see nearly 360 degrees around them—an essential adaptation for spotting predators. According to Marty Banks, a principal investigator at UC Berkeley, the elongated pupil lets in more light, improving visibility in the direction of potential threats. Additionally, the narrow vertical shape sharpens horizontal contours, aiding sheep in navigating their environment while fleeing danger. While most predators have vertical or circular pupils, the mongoose stands out with a pupil shape similar to that of sheep, defying typical classifications in the animal kingdom. This diversity in pupil shapes reflects the varied evolutionary adaptations among species for survival.
Published: Dec 12 2025, 2 pmeznews.inA comprehensive study involving nearly half of France's population has revealed that young and middle-aged individuals vaccinated with mRNA COVID-19 vaccines are 74% less likely to die from the virus. Furthermore, vaccinated individuals showed a 25% lower risk of dying from any cause over four years compared to their unvaccinated counterparts. Conducted by researchers from the French National Agency for the Safety of Medicines and Health Products, the study analyzed health data from 28.7 million people, focusing on those aged 18 to 59 who received their first mRNA vaccine dose between May and October 2021. The findings contradict recent claims made by FDA officials regarding vaccine-related deaths, reinforcing the safety of mRNA vaccines. While the study's results suggest a significant mortality benefit associated with vaccination, the authors acknowledge potential confounding factors that may influence these outcomes. The research is published in JAMA Open.
