Here, temperatures can plunge below freezing, but life persists due to phenomena like freezing-point depression, which prevents seawater from solidifying even at sub-zero temperatures. Ice forms in seawater, but as it does, it increases in density, causing saltwater to sink before it can freeze, requiring significant depth for solid ice formation. Among the remarkable inhabitants of these icy depths are icefish, which have adapted to survive without red blood cells or hemoglobin, relying instead on antifreeze proteins to prevent their blood from freezing. While their colorless blood carries only a fraction of the oxygen found in typical fish, the high dissolved oxygen levels in their environment allow them to thrive, albeit at a high energetic cost. These adaptations highlight the resilience of life in extreme conditions.

Researchers from the Korea Research Institute of Standards and Science (KRISS), alongside international collaborators, utilized an innovative dynamic diamond anvil cell (dDAC) to compress water rapidly, achieving a pressure of 2 gigapascals—nearly 20,000 times atmospheric pressure. This method allowed them to form a unique crystalline structure characterized by a complex unit cell and a flattened rectangular shape. The discovery adds to the 20 known ice phases and may have significant implications for understanding the conditions on icy moons of Jupiter and Saturn, potentially offering insights into the origins of life in extreme environments. The findings were published in the journal *Nature Materials*.
Published: Nov 07 2025, 10 pmeznews.inIn a groundbreaking discovery, astronomers have detected Complex Organic Molecules (COMs), potential precursors to life, in ice surrounding the young star ST6 in the Large Magellanic Cloud (LMC), marking the first such finding outside the Milky Way. Using the James Webb Space Telescope (JWST), researchers led by Dr. Marta Sewilo identified five COMs, including methanol, ethanol, and acetic acid—the latter being the first conclusive detection of this molecule in space. The LMC, characterized by a lower abundance of heavier elements and increased ultraviolet light, offers insights into the formation of COMs in the universe's early epochs. While the presence of these molecules does not indicate life, they are essential to understanding the origins of organic compounds. The study highlights the importance of advanced instruments like JWST in exploring cosmic chemistry, with potential implications for industrial and pharmaceutical applications. The findings are detailed in The Astrophysical Journal Letters.

This circular tunnel, measuring 4.1 to 5.9 meters in diameter, transports water from several reservoirs to the Hillview Reservoir in Yonkers, supplying 50 to 80 percent of New York City’s drinking water. Constructed between the late 1930s and 1940s, the aqueduct utilized 31 vertical shafts for access, allowing workers to carve through solid bedrock. However, it has been leaking approximately 35 million gallons per day since the 1990s, prompting a $1 billion repair plan announced in 2010, with work now expected to begin post-2027. While the aqueduct is celebrated for its high-quality water, repairs may temporarily alter its taste, as noted by Rohit T. Aggarwala, commissioner of NYC's Department of Environmental Protection.
Published: Nov 07 2025, 12 pmeznews.inIn a fascinating exploration of our connection to the age of dinosaurs, Professor Steve Brusatte, a renowned palaeontologist, suggests that dinosaur meat could have been edible and potentially delicious. Brusatte, who has contributed to the understanding of dinosaur behavior and anatomy, posits that many herbivorous dinosaurs, such as the Brontosaurus and Triceratops, would likely have been tasty, while carnivorous species like Tyrannosaurus rex might not have been as palatable. This inquiry into the culinary possibilities of dinosaurs draws parallels with modern-day relatives, such as birds and crocodiles, which are commonly consumed. However, caution is warranted, as some birds, like the hooded pitohui, possess potent neurotoxins due to their diet, raising questions about the safety of consuming certain species. Ultimately, while the idea of dining on dinosaur meat is intriguing, it remains a speculative venture into the past.
Published: Nov 07 2025, 8 pmeznews.inA recent study from École Normale Supérieure in Paris has revealed that the brain employs distinct mechanisms when recalling familiar images compared to viewing them in real-time. Researchers, led by Anthony Clement and Dr. Catherine Tallon-Baudry, examined 28 volunteers using EEG technology while they visualized a map of France and focused on specific regions. The findings indicated that different brain areas were activated during mental imagery tasks, particularly in the left inferior frontal gyrus, which is linked to language processing and internal attention. This contrasts with the brain's response during direct visual perception, suggesting that spatial attention in mental imagery does not rely on the same neural pathways as visual attention. The study, published in the Journal of Neuroscience, raises questions about the evolutionary reasons behind these differences and their implications for understanding conditions like aphantasia, where individuals lack the ability to visualize.
Published: Nov 07 2025, 4 pmeznews.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 significantly influenced by their suitability for farming; they are slow, non-flying birds that thrive in human proximity. Initially domesticated for cockfighting, their culinary potential eventually overshadowed their sporting use. The Roman Empire popularized chicken and its eggs, but it wasn't until World War II, when red meat became scarce, that chicken truly surged in popularity. While other birds like pigeons and geese are also edible, they are less favored due to farming challenges and taste preferences. Ultimately, chickens' ease of domestication and palatability have solidified their place as a primary source of poultry in diets worldwide.
Published: Nov 04 2025, 12 ameznews.inChinese astronauts aboard the Tiangong space station have made history by conducting the first barbecue in space, cooking chicken wings and beef using a newly delivered hot air oven. This advancement marks a significant leap in space food technology, allowing for actual cooking rather than just heating, with temperatures reaching 190 degrees Celsius. Liu Weibo, deputy chief designer at the China Astronaut Research and Training Center, emphasized that this innovation enhances astronauts' dining experiences, enabling them to enjoy special meals on occasions like weekends and holidays. The oven is designed with safety in mind, featuring secure food placement and a smoke purification system to prevent hazards in the microgravity environment. While cooking times may be longer—28 minutes for crispy wings—the development promises a more varied and appetizing diet for astronauts, reflecting ongoing improvements in space food technology since the early days of freeze-dried and tube-packaged meals.
Published: Nov 05 2025, 6 pmeznews.inThe year 536 CE is often cited as one of the most calamitous periods in human history, marked by a mysterious volcanic eruption that plunged the Northern Hemisphere into darkness and triggered a dramatic climate shift. While the exact volcano remains uncertain, evidence suggests eruptions in either El Salvador or Iceland caused a "volcanic winter," leading to plummeting temperatures and agricultural collapse. Historical accounts from figures like Roman statesman Cassiodorus and Byzantine historian Procopius describe a sun obscured by a foggy haze, resulting in widespread famine and disease, including the bubonic plague. This period also heralded the onset of the Late Antique Little Ice Age, which contributed to the decline of the Eastern Roman Empire and prompted migrations of nomadic tribes in Central Asia. Conversely, the Arabian Peninsula experienced increased rainfall, setting the stage for the rise of the Arab Empire by the seventh century.
Published: Nov 03 2025, 8 pmeznews.inWhile scientific inquiries often delve into the universe's grand mysteries, many people are curious about simpler, yet intriguing questions, such as why humans float more easily in saltwater. This phenomenon is particularly evident in places like the Dead Sea, where the high salinity significantly increases water density. According to Archimedes' principle, an object will float if the buoyant force acting on it exceeds its weight. Since the human body is composed of approximately 60% water, it is naturally less dense than freshwater, allowing for buoyancy. However, when salt is added to water, it dissolves and increases the water's density, enhancing the upward buoyant force. In the Dead Sea, with a salinity of around 277 g/kg, the water density reaches approximately 1240 kg/m³, making it nearly impossible to sink, thus providing a unique floating experience for bathers.
