Scientifically termed _Muscae volitantes_ or "flying flies," these are not insects but rather tiny particles, such as bits of tissue or protein clumps, suspended in the vitreous humor—the gel-like substance that maintains the eye's shape. As these floaters drift, they cast shadows on the retina, leading to the unusual visual effects many people notice. Additionally, a phenomenon known as the blue field entoptic phenomenon allows observers to see white blood cells moving in the capillaries of the retina against a blue backdrop, as the blue light is not absorbed by these cells. This intriguing interplay of vision highlights the complexities of our visual perception. 
Published: Nov 29 2025, 4 pmeznews.inA remarkably preserved dinosaur embryo, nicknamed Baby Yingliang, has been discovered within a fossilized egg that had been stored for over a decade in a Chinese museum. Estimated to be between 66 and 72 million years old, this specimen belongs to the oviraptorosaur group of feathered theropods and measures approximately 27 centimeters (10.6 inches) in length. Notably, Baby Yingliang exhibits a posture akin to that of modern bird embryos, known as "tucking," where the head is positioned under the wing, a behavior crucial for successful hatching. This finding suggests that such developmental traits may have originated in theropod ancestors long before the emergence of birds. Researchers emphasize that while this discovery provides valuable insights, further fossil studies are necessary to draw definitive conclusions about dinosaur embryonic development. The study was published in the journal iScience, highlighting the evolutionary connections between dinosaurs and contemporary avian species.
Published: Dec 03 2025, 12 ameznews.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 for 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 simple, it should not replace more effective strategies for preventing condensation and its associated problems.

A common discomfort during take-off is the sensation of dropping, which many passengers experience shortly after the plane ascends. Airline captain and fear of flying coach, Simon, explains that this feeling is a normal part of the flight process. After take-off, pilots reduce thrust to allow the aircraft to accelerate more efficiently, which can create a perception of a dip due to changes in engine noise and the plane's angle. This sensation, akin to the weightlessness felt on roller coasters, is temporary and crucial for engine preservation and noise reduction for those near airports. Simon reassures nervous flyers that this moment is just a transition, and soon the flight will stabilize as the aircraft continues to climb smoothly.
Published: Dec 03 2025, 1 ameznews.inFish do not possess tongues in the traditional sense, as defined by a muscular organ capable of independent movement, which is essential for complex speech in humans. Instead, they have a basihyal, a bony structure that resembles a tongue but lacks the dexterity and taste buds associated with mammalian tongues. This organ evolved to protect the ventral aorta, a vital blood vessel near the mouth, and aids in food manipulation during feeding. Different fish species exhibit variations in the basihyal's size and function; for instance, sheepshead fish have teeth attached to theirs for crushing prey, while archerfish use it to shoot jets of water at insects. Interestingly, fish can taste through their skin, fins, and lips, with catfish boasting around 680,000 taste buds. However, the basihyal is also vulnerable to parasitic isopods that can replace it entirely, highlighting the complexities of fish anatomy.
Published: Nov 29 2025, 3 pmeznews.inThresher sharks, known for their distinctive long tails and large eyes, exhibit a unique hunting technique called "tail-whipping," which allows them to stun prey such as sardines and mackerel. Their tails can reach lengths of up to 3 meters, accounting for nearly half their body size, and are capable of creating cavitation bubbles that generate sound and light when they strike. A recent study revealed significant anatomical adaptations in their vertebrae that support this hunting method, with variations observed across different developmental stages. Thresher sharks typically hunt at night, rising to the surface to target shoaling fish, while during the day, they dive deep in search of squid and octopus. There are three species of thresher sharks, with the common thresher being the largest, reaching lengths of up to 5.8 meters. These sharks inhabit tropical and temperate seas worldwide, showcasing their adaptability in various marine environments.
Published: Dec 02 2025, 10 pmeznews.inInterstellar comet 3I/ATLAS, recently observed, is exhibiting signs of "cryovolcanism," suggesting it may be a primitive carbonaceous object akin to those found in the outer solar system. A preprint study indicates that its spectral characteristics closely match pristine carbonaceous chondrites from NASA's Antarctic meteorite collection, hinting at a composition enriched in native metals and undergoing significant aqueous alteration as it approaches the Sun. The comet, estimated to be between 0.3 and 5.6 kilometers in diameter, has likely traveled through the interstellar medium for billions of years, showcasing remarkable mechanical strength. Its cryovolcanic activity, characterized by subsurface materials erupting as ice volcanoes, aligns with expected behaviors of trans-Neptunian objects. Researchers emphasize the importance of future missions, like ESA's Comet Interceptor, to directly sample such interstellar visitors, which could enhance our understanding of planetary formation and the chemical evolution of celestial bodies.
Published: Dec 02 2025, 11 pmeznews.inIn a groundbreaking development coinciding with World AIDS Day, a 60-year-old man from Berlin, known as B2, has become the seventh documented patient to have HIV eliminated from his body, following treatment for acute myeloid leukemia. This case is particularly notable as the donor stem cells, which carried only one copy of the CCR5 Δ32 gene associated with HIV resistance, were deemed less promising than in previous cases. B2, diagnosed with HIV in 2009, has shown no trace of the virus six years after halting anti-retroviral therapy. The findings raise hopes for more accessible treatments, as the presence of a single CCR5 Δ32 gene could expand the pool of potential donors. However, experts caution against overestimating the replicability of this success, as the mechanisms behind the cure remain poorly understood. The study is published in *Nature*, alongside other research on HIV advancements.
Published: Dec 01 2025, 11 pmeznews.inMeasles cases in Europe surged dramatically in 2018, with 82,596 new infections reported—three times the number from 2017 and 15 times the record low in 2016, marking the highest incidence in a decade. The World Health Organization (WHO) reported 72 fatalities linked to the disease last year, with 92% of cases concentrated in just ten countries, including Ukraine, Serbia, and France. While immunization rates improved significantly in 2017, reaching a record 90% for the second vaccine dose, the WHO warns that local gaps in vaccination coverage could lead to further outbreaks. Dr. Zsuzsanna Jakab, WHO's regional director for Europe, emphasized the need for targeted efforts to ensure equitable access to vaccines and to rebuild public trust in immunization, particularly in areas affected by anti-vaccine sentiments and conflict, such as Ukraine, where vaccination rates plummeted to 31% during the ongoing crisis.
