In a surprising revelation, the first-ever footage of a Hoffmann's two-toed sloth has confirmed that these notoriously slow creatures do indeed fart, dispelling the long-held belief that they absorbed digestive gases back into their bloodstream. The video, shared by veterinarian Andrés Bräutigam and broadcaster Lucy Cooke, showcases the sloth's flatulence, which is significant enough to interfere with medical imaging and even aid in buoyancy while swimming. Sloths, which primarily consume leaves and fruits, have a notably slow metabolism, leading to infrequent bowel movements. This discovery adds to the growing interest in animal flatulence, a topic that has sparked curiosity and research, including a book titled *Does It Fart?* by Dr. Dani Rabaiotti. The findings not only enhance our understanding of sloth behavior but also contribute to the broader study of animal digestion and gas emissions. 
Published: Jul 22 2025, 11 pmeznews.inPhysicists have made a groundbreaking observation of the Transverse Thomson Effect, a phenomenon theorized over 174 years ago, which could enhance temperature management in various applications. This effect, related to the Seebeck effect used in thermoelectric generators, was first noted by Lord Kelvin in 1851, highlighting the relationship between temperature gradients and electrical currents. Researchers from two Japanese institutes successfully demonstrated the effect using a bismuth-antimony semimetal, applying a current, temperature gradient, and magnetic field at right angles. Their findings revealed that the Transverse Thomson Effect can induce uniform heating or cooling across the material, with the potential to be amplified in other substances. The study, published in *Nature Physics*, estimates this effect to be about 15% as strong as the original Thomson Effect, offering hope for advancements in the search for dark matter and other scientific applications.
Published: Jul 19 2025, 11 pmeznews.inChongqing, a sprawling megacity in China, holds the title of the world's largest city by area, covering over 82,400 square kilometers—comparable to the size of Ireland or Austria. With a population exceeding 32 million, it surpasses major cities like New York and Mexico City, which are significantly smaller in both area and population. Nestled at the confluence of the Jialing and Yangtze rivers, Chongqing's unique geography features neighborhoods clinging to cliffs and a complex network of elevated roads and metro lines. While its vast size includes extensive rural regions, over 70% of its population resides in the urban area. Chongqing's rapid growth began in the late 20th century, driven by China's economic reforms, transforming it into a vital transportation hub with a rich history dating back over 3,000 years. Despite potential population declines, Chongqing remains a symbol of China's urbanization and development.
Published: Jul 23 2025, 2 pmeznews.inThe animal kingdom showcases a remarkable variety of reproductive organs, each with unique adaptations. The Argentine blue-bill lake duck features a corkscrew-shaped penis, measuring up to 42.5 centimeters, designed to navigate the female's similarly twisted anatomy. In contrast, the short-beaked echidna boasts a four-headed penis, resembling a rotating shaver, which is exclusively used for reproduction. Barnacles, known for their adhesive nature, possess retractable penises that can extend up to 20 centimeters, earning them the title for the longest penis relative to body size. Leopard slugs engage in elaborate mating rituals, using bright blue penises that emerge from their heads. Additionally, some species, like koalas and certain sharks, have dual reproductive organs, while humans, with comparatively larger penises and smaller testicles than other primates, stand out in the evolutionary landscape. This diversity highlights the fascinating adaptations of animal reproductive strategies.
Published: Jul 23 2025, 9 ameznews.inIn Utah's Fishlake National Forest, a colossal organism known as Pando, a quaking aspen (_Populus tremuloides_), spans 42.6 hectares (105.3 acres) and consists of approximately 47,000 genetically identical stems, making it one of the largest and oldest living organisms on Earth. Recent genetic analysis suggests Pando's age could range from 16,000 to 80,000 years, highlighting its remarkable longevity. Researchers found that while Pando clones itself asexually due to its triploid nature, which may enhance its fitness, the genetic variation among its stems is more complex than expected. The study revealed 4,000 unique genetic variants, indicating a mosaic of mutations rather than localized clusters. This groundbreaking research aims to deepen understanding of clonal organisms, with co-author William Ratcliff calling for further exploration of such unique life forms. Pando's resilience is particularly notable as it faces threats from deer grazing.
Published: Jul 20 2025, 12 ameznews.inThe king cheetah, a rare big cat found in southern Africa, challenges the conventional understanding of cheetah patterns. Unlike typical cheetahs, which have rounded black spots, king cheetahs display a unique coat with elongated spots and thick stripes along their spines. Initially thought to be a hybrid of a leopard and a hyena, or even a separate species (_Acinonyx rex_), the true nature of the king cheetah's distinctive appearance was revealed in 2012. Researchers discovered that a mutation in the _Taqpep_ gene, responsible for coat patterns in domestic cats, also accounts for the king cheetah's blotchy design. Conservationist Ann van Dyk played a crucial role in this research, maintaining detailed breeding records that supported the genetic findings. While only about ten king cheetahs are believed to exist in the wild, conservation efforts may help increase their numbers in the future.
Published: Jul 23 2025, 10 ameznews.inNASA's latest simulations indicate that asteroid 2024 YR4, discovered in December 2024, has a 4.3% chance of impacting the Moon on December 22, 2032, a significant increase from earlier estimates. Initially, the asteroid posed a 1% risk of colliding with Earth, which has since dropped to just 0.004%. If it strikes the Moon, it could create a crater approximately 1 kilometer wide and release energy equivalent to 6.5 megatons of TNT, potentially ejecting up to 108 kilograms of lunar material into space. This debris could lead to spectacular meteor showers on Earth, but it also poses risks to satellites in orbit, with the potential for increased meteoroid impacts. While the event could be visually stunning, NASA emphasizes that the Moon's orbit would remain unchanged. Observations of the asteroid will resume in 2028 as it returns to visibility.
Published: Jul 19 2025, 4 pmeznews.inRussian physicist Alexander Berezin has proposed a troubling explanation for the Fermi Paradox, which questions why we have yet to encounter extraterrestrial civilizations. His theory, dubbed the “First in, last out” solution, suggests that advanced civilizations, once capable of interstellar expansion, may inadvertently eliminate other life forms without malice, akin to a construction crew demolishing an anthill. Berezin posits that humanity might not be the innocent bystanders in this scenario; rather, we could be the future destroyers of countless civilizations. He argues that the drive for growth and expansion could overshadow the existence of other life, drawing parallels to historical colonialism and capitalism. While his hypothesis raises concerns about humanity's future, Berezin remains hopeful that we might discover alien life before embarking on a destructive path, potentially allowing us to evolve into a more benevolent civilization.
Published: Jul 22 2025, 2 pmeznews.inForty-six years after Voyager 1's historic flyby of Jupiter, the magnetic data it collected remains a source of fascination, revealing the planet's complex magnetosphere. This region, where Jupiter's powerful magnetic field—16 to 54 times stronger than Earth's—interacts with the solar wind, creates a bow shock akin to a sonic boom. Voyager 1's findings in 1979, which showed a smaller magnetosphere than expected due to intense solar wind, laid the groundwork for subsequent missions, including Juno, which crossed the bow shock in 2016. Juno's observations unveiled an even more intricate boundary structure, with the magnetosphere extending up to 745 million kilometers behind Jupiter. As scientists continue to study this extreme world, new discoveries, such as previously unseen plasma waves, highlight the ongoing quest to understand Jupiter and its magnetic behavior, crucial for insights into other celestial bodies across the universe.
