Antarctica, the last major landmass discovered by humans around 1300 CE, remains unique in its governance and environmental extremes. Governed by the 1959 Antarctic Treaty, which prohibits military activity and territorial claims, the continent is claimed by seven nations, including the UK, Argentina, and Australia, though most countries do not recognize these claims. Spanning approximately 13.7 million square kilometers, Antarctica is the world's largest, driest, windiest, and coldest desert, with temperatures plummeting to -89.2°C. Its harsh conditions have led researchers to liken it to "White Mars," making it a focal point for studies related to space exploration. Despite its vastness, mapping Antarctica has proven challenging, with accurate maps only emerging in the 1980s. Interestingly, Polynesian explorers may have reached its waters centuries before European expeditions confirmed its existence in 1820, raising questions about ownership and discovery. ![sources](/icos/news.png)
Published: Jul 26 2024, 9 pmeznews.inA remarkably well-preserved Neanderthal skeleton, dubbed Shanidar Z, has been discovered in Iraq's Shanidar Cave, marking the most significant find of its kind in over 25 years. This female, who lived approximately 75,000 years ago, was found among a cluster of burials, suggesting complex funerary practices that challenge previous perceptions of Neanderthals as primitive. The skeleton's reconstruction reveals a face surprisingly similar to modern humans, highlighting the potential for interbreeding between species. Researchers painstakingly restored her skull, which had been crushed, to create a lifelike model. While the notion of "flower burials" has been debated, with some evidence suggesting pollen may have been introduced by bees, the findings underscore Neanderthals' emotional depth and social structures. Professor Graeme Barker emphasized that these discoveries reveal Neanderthals may have contemplated death in ways akin to modern humans, reshaping our understanding of this ancient lineage. ![sources](/icos/news.png)
Published: Sep 08 2024, 2 ameznews.inCats are known for their peculiar traits, including the mysterious folds on their ears, referred to as Henry's Pockets. This small cutaneous marginal pouch, found on the outer ear or pinna, is not unique to cats, as it also appears in species like dogs and bats. The origin of the term "Henry's Pocket" remains unclear, with some speculating it may honor Joseph Henry, a scientist known for his work in electromagnetism. While theories suggest these pouches could enhance hearing by improving ear movement or amplifying sound, no definitive evidence supports these claims. Cats possess an impressive hearing range, from 48Hz to 85kHz, and the pouches may assist in detecting higher-pitched sounds. Despite their potential functions, some believe these pouches could be vestigial. However, they are known to attract pests like fleas and ear mites, necessitating regular cleaning by pet owners. ![sources](/icos/news.png)
Published: Sep 02 2024, 11 pmeznews.inIn a remarkable discovery in 2016, geologists unearthed water over 2.6 billion years old in a Canadian mine, making it the oldest water on Earth. This find succeeded a previous discovery by the same team, during which lead geologist Professor Barbara Sherwood Lollar famously tasted the ancient liquid. While this act might evoke horror movie clichés, Sherwood Lollar explained that tasting can provide insights into the water's age, with saltier samples indicating greater antiquity. She described the water as "very salty and bitter," far saltier than seawater. Although it may not be palatable, the water's analysis revealed traces of ancient microorganisms, suggesting life has existed in these fluids over geological timescales. Sherwood Lollar emphasized the significance of these findings, indicating that the microbial signatures point to a long history of life in this ancient water, making it scientifically invaluable despite its unappetizing taste. ![sources](/icos/news.png)
Published: Sep 07 2024, 8 pmeznews.inIn a remarkable encounter, hikers in Sumatra stumbled upon one of the world's rarest rabbits, the Sumatran striped rabbit (_Nesolagus netscheri_), during a trek in June 2022. This elusive species, characterized by its distinctive dark stripes on rusty-colored fur, has been sighted only a handful of times in the past 50 years, primarily due to its nocturnal habits and preference for remote forest habitats. The hikers were fortunate to observe the curious rabbit hopping around their feet, illuminated by their torches. Previous sightings include photographs taken in 1998 and 2000, with a notable incident in 2021 when an injured rabbit was rescued and later released. Experts, including Deborah Martyr from Kerinci Seblat National Park, emphasize the limited knowledge about this species, with historical specimens dating back to the Dutch colonial era. The sighting highlights the ongoing need for conservation efforts in Sumatra's biodiverse ecosystems. ![sources](/icos/news.png)
Published: Sep 02 2024, 10 pmeznews.inUnusual atmospheric conditions are troubling scientists as Antarctica's polar vortex deviates from its typical circular form, resembling a stretched-out peanut. NASA's Global Modeling and Assimilation Office has reported that this winter, the southern polar vortex is elongated, warmer, and significantly weaker than usual, with stratospheric temperatures soaring to record highs of 17°C (31°F) in early August, compared to the typical -80°C (-112°F). This instability raises concerns about a potential collapse or a shift in the vortex's direction, reminiscent of a similar event in 2002. The unusual stratospheric conditions correlate with a prolonged heatwave in Antarctica, where temperatures have been 10 to 12°C (18 to 21.6°F) above average. While the relationship between surface and stratospheric phenomena is complex, experts note that variations in sea surface temperatures and sea ice may influence these large-scale weather systems. Meanwhile, the ozone layer over the Southern Hemisphere is experiencing a remarkable recovery. ![sources](/icos/news.png)
Published: Sep 07 2024, 7 pmeznews.inA spectacular display of auroras may soon light up the skies, thanks to the Russell-McPherron effect, which is particularly pronounced around the equinoxes. This phenomenon, first theorized in 1973 by geophysicists Christopher Russell and Robert McPherron, occurs when the Earth's magnetic field aligns with the Sun's, enhancing the capture of charged particles from solar winds that create auroras. Typically, aurora season runs from late August to mid-April, with peak activity in September and March. This year, the situation could be intensified by the current solar maximum, a phase of heightened solar activity that has already produced the strongest geomagnetic storm in two decades. As a result, observers may have the chance to witness even more vivid auroras than seen previously, particularly if significant sunspots emerge around the equinoxes. ![sources](/icos/news.png)
Published: Sep 07 2024, 9 pmeznews.inLong-distance runners and walkers frequently experience gastrointestinal distress, leading to incidents of incontinence during races. Notable examples include French walker Yohann Diniz, who finished eighth in 2016 despite fainting from gastrointestinal issues, and Paula Radcliffe, who famously stopped mid-race during the 2005 London Marathon. A study from 1992 revealed that 62% of long-distance athletes reported stopping for bowel movements during training, with 12% experiencing full fecal incontinence while running. Contributing factors include reduced blood flow to the gastrointestinal organs during intense exercise, difficulty controlling the anal sphincter under physical strain, and the jostling of the body while running. Stress and dietary choices, such as Radcliffe's pre-race meal, can also exacerbate these issues. Overall, up to 90% of endurance race participants report some gastrointestinal symptoms, highlighting the unique challenges faced by athletes in this demanding sport. ![sources](/icos/news.png)
