Approximately 76% of individuals without visual impairments experience "floaters," which are small, moving shapes resembling worms that become noticeable against bright backgrounds like the sky or a white screen. Scientifically termed *Muscae volitantes*, these floaters are not insects but rather tiny particles, such as bits of tissue or protein clumps, suspended in the vitreous humor—the gel-like substance in the eye. As these floaters drift, they cast shadows on the retina, leading to the unusual visual effects many people report. Additionally, a phenomenon known as the blue field entoptic phenomenon allows observers to see moving white blood cells in the retina's capillaries against a blue backdrop, as these cells slow down red blood cells, creating visible patterns. This intriguing interplay of eye anatomy and light perception sheds light on common visual experiences. 
Published: Nov 29 2025, 4 pmeznews.inAs winter approaches, UK residents are being encouraged to place bowls of salt on their windowsills to combat damp and mold caused by condensation. This advice stems from salt's hygroscopic properties, which allow it to absorb moisture from the air. However, experts caution that while salt can help, its effectiveness is limited, particularly in typical UK humidity levels, which range from 30% to 60%. Salt only begins to absorb significant moisture at higher humidity levels, around 74%. Therefore, while it may provide some relief, proper ventilation remains crucial in managing condensation. Opening windows or using built-in vents can significantly reduce moisture buildup, making the need for salt bowls less necessary. Ultimately, while the salt method is easy and requires minimal effort, it should not replace more effective strategies for preventing condensation in homes.
Published: Nov 29 2025, 3 pmeznews.inThe moose, scientifically known as *Alces alces*, holds the title of the tallest mammal in North America and the largest deer species globally, with the Alaska moose subspecies reaching heights of 1.8 meters (6 feet) and weights up to 725.7 kilograms (1,600 pounds). Historically hunted for their meat since the last Ice Age, moose are still a vital food source today, with their meat, referred to as venison, enjoyed in various forms such as steaks and sausages. Moose meat is praised for its rich flavor, often likened to a blend of venison and beef, and is a nutritious option, high in protein and iron. However, concerns about contaminants in their organs persist. Found across the Northern Hemisphere, moose are herbivores, primarily feeding on plants, which helps mitigate contaminant levels compared to carnivorous animals. The term "moose" originates from the Algonquin language, meaning "eater of twigs."
Published: Nov 29 2025, 1 ameznews.inCincinnati Zoo is celebrating the remarkable milestone of Lazzie, the world's oldest little penguin, who has just turned 25. While this age may not seem extraordinary for humans, it is impressive for a little penguin (_Eudyptula minor_), which typically lives less than 20 years in managed care. Lazzie, the first little penguin to hatch at the zoo in 2000, has thrived thanks to the dedicated care from the zoo's staff, allowing her to keep pace with younger members of her colony. Little penguins, averaging just 30 centimeters tall and weighing over a kilogram, are often referred to as "fairy penguins." Despite being classified as Least Concern by the IUCN, they face threats from predators like dogs. However, with protective measures in place in Australia and New Zealand, Lazzie's longevity highlights the potential for these charming birds to thrive under proper care.
Published: Nov 29 2025, 9 ameznews.inVladimir Demikhov, a Soviet scientist born in 1916, is often remembered for his controversial "two-headed dog" experiments rather than his pioneering contributions to organ transplantation. Raised in a peasant family, Demikhov showed an early interest in biology, leading to his groundbreaking work in the 1930s, including the first total artificial heart prototype. His career was interrupted by World War II, but he later achieved significant milestones, such as the first successful heart-lung transplant and coronary bypass operation in dogs. However, his most infamous work involved head transplants, where he grafted the head of a smaller dog onto a larger one, resulting in a creature that displayed reflexive behaviors. Despite the technical achievements, his experiments sparked outrage in the medical community, overshadowing his legitimate contributions to surgery. In his later years, Demikhov received some recognition for his work, but his legacy remains marred by the ethical implications of his experiments.
Published: Nov 26 2025, 3 pmeznews.inSaturn's moon Enceladus has emerged as a prime candidate in the search for extraterrestrial life, thanks to its hidden liquid ocean beneath an icy crust and evidence of geothermal activity. The European Space Agency (ESA) has announced a groundbreaking mission to explore Enceladus, part of its Voyage 2050 strategy, which aims to launch a solar-powered orbiter and lander by the 2040s, with a target arrival in 2052. The lander will investigate the moon's plumes at the South Pole, allowing scientists to sample the ocean directly without drilling through ice. ESA's commitment to this mission reflects its broader strategy for space exploration, which includes various ambitious projects such as the Rosalind Franklin rover to Mars and the New Athena X-ray observatory. As ESA increases its science budget, the quest to answer whether life exists beyond Earth is gaining momentum, with significant missions planned for the coming decades.
Published: Nov 29 2025, 9 ameznews.inThe genus _Poltys_, a remarkable group of orb-weaver spiders, exemplifies the art of camouflage, often resembling twigs or leaves to evade predators. These nocturnal spiders construct spiral-shaped webs at dusk to capture flying insects, consuming their webs by morning, which leaves them vulnerable during the day. To enhance their disguise, _Poltys_ spiders have evolved unique anatomical features that allow them to blend seamlessly into their surroundings, curling up and remaining motionless for hours. This evolutionary adaptation, honed over generations, has resulted in various species, including the Dead Leaf Spider (_Poltys idae_), which mimics both live and dry foliage with astonishing detail. Found across Africa, Asia, and Australia, _Poltys_ spiders showcase the gradual process of natural selection, while other spider genera, like bird-dung spiders, employ different strategies to avoid detection, further highlighting the diversity of survival tactics in the animal kingdom.

Published: Nov 29 2025, 10 ameznews.inComet 3I/ATLAS, the latest interstellar visitor to our Solar System, is on a trajectory that may lead to a significant encounter with Jupiter before it departs towards the Gemini constellation in 2026. A new pre-print study suggests that the comet, likely originating from the Sagittarius direction, could experience gravitational perturbations from both Mars and Jupiter, with the latter having a more substantial impact due to its proximity. The research indicates that 3I/ATLAS may have traveled alone for up to 10 billion years before entering our Solar System, possibly from the Milky Way's thick disk. While the exact origin remains uncertain, astronomers are keen to observe the comet as it approaches Jupiter, particularly between March 9 and 22, 2026, to gather more data on its trajectory and any non-gravitational forces affecting its path.
Published: Nov 26 2025, 2 ameznews.inThe Oxford-AstraZeneca COVID-19 vaccine, known as Vaxzevria, is set to be withdrawn globally nearly 3.5 years after its initial approval, a decision attributed to a surplus of updated vaccines and declining demand. Experts, including Professor Adam Finn from the University of Bristol, suggest that the vaccine's effectiveness has diminished due to the emergence of new variants, making its continued production commercially unviable. Despite its discontinuation, AstraZeneca noted that the vaccine saved over 6.5 million lives in its first year of use and was pivotal in combating the pandemic. While the vaccine faced scrutiny over rare blood clotting issues, the risk was found to be low, with COVID-19 itself posing a greater threat. Experts acknowledge the vaccine's significant role in the pandemic response, but agree that more effective and safer alternatives are now available, indicating that its time may have passed.
