The Parker Solar Probe has achieved a historic milestone by completing the closest-ever pass to the Sun by a human-made spacecraft, coming within 6.1 million kilometers (3.8 million miles) of the solar surface on December 24. Moving at an astonishing speed of approximately 690,000 kilometers per hour (430,000 miles per hour), the probe successfully transmitted a beacon signal back to NASA on December 26, confirming its good health and operational status. Launched in 2018, the Parker Solar Probe aims to explore the Sun's corona, investigating why it reaches temperatures of up to 980°C (1,800°F) and tracing the origins of solar wind. This 22nd flyby marks the closest approach, with two additional passes scheduled for March and June 2025. NASA scientists eagerly await detailed telemetry data expected on January 1, which will provide insights into the Sun's enduring mysteries. 
Published: Dec 27 2024, 10 pmeznews.inGogottes, also known as concretions, are striking natural formations found primarily in the Fontainebleau region of France, where they have captivated observers with their abstract, swirling shapes. Formed approximately 30 million years ago when a layer of quartz was left behind after water receded, these unique structures emerged as silica-rich water permeated the sand, bonding it into hard sandstone over millennia. Their unusual designs have sparked pareidolia, leading people to see familiar shapes within them, further enhancing their allure. Historically, gogottes have been highly prized; King Louis XIV famously adorned the gardens of Versailles with these natural sculptures. Today, they continue to be celebrated for their geological significance and aesthetic appeal, with notable specimens displayed in institutions like the Natural History Museum in London and the Royal Ontario Museum in Canada.
Published: Dec 24 2024, 12 ameznews.inA remarkable discovery in 1822 near Klütz, Germany, involving a white stork with a spear embedded in its neck, significantly advanced European understanding of bird migration. For centuries, theories about the winter whereabouts of birds ranged from hibernation to fantastical notions of flying to the Moon or engaging in mythical battles with pygmies. The stork, which had traveled an astonishing 3,200 kilometers to Africa before returning to Germany, provided concrete evidence of migratory behavior, debunking the bizarre beliefs that birds transformed into different species for the winter. This stork, later dubbed the "arrow stork" (_Pfeilstorch_), became a symbol of the shift in scientific understanding, although its fate was grim, as it was killed and stuffed shortly after its discovery. The incident marked a pivotal moment in ornithology, moving Europe closer to grasping the complexities of avian migration.
Published: Dec 24 2024, 5 pmeznews.inThe Euphrates River, once a lifeline for millions in Turkey, Syria, and Iraq, is drying up at an alarming rate, primarily due to chronic droughts and climate change, rather than apocalyptic predictions. A 2021 report from Iraq's Ministry of Water Resources warned that the river system could run dry by 2040, with satellite data revealing a significant loss of freshwater in recent years. This environmental crisis threatens the livelihoods of approximately 60 million people who depend on the river for water. As international cooperation over water management has stalled, tensions are rising, raising fears of potential "water wars" in the region. Additionally, the lack of clean water is exacerbating health crises, with increasing cases of waterborne diseases reported in Iraq. The situation underscores the urgent need for sustainable water management in a region historically rich in resources but now facing severe scarcity.
Published: Dec 28 2024, 12 pmeznews.inMoqui marbles, peculiar iron concretions found across the deserts of Utah and neighboring states, have intrigued scientists for decades. Ranging in size from a pea to a grapefruit, these spherical formations are composed of iron oxide and sandstone, formed millions of years ago through groundwater processes beneath ancient rock layers. Named after the Hopi Tribe's legend of ancestral spirits playing marbles, the marbles became visible only after weathering eroded their outer layers. Research indicates that the oldest marbles date back 25 million years, while others are as young as 2 to 5 million years. Similar structures have been discovered globally, including in Mongolia and even on Mars, where they are dubbed "blueberries." These Martian formations may provide evidence of past water on the planet, suggesting a shared geological history between Earth and Mars.
Published: Dec 28 2024, 10 ameznews.inIn a groundbreaking achievement, the European Space Agency (ESA) and Telesat have successfully established the first-ever 5G connection to a Low Earth Orbit (LEO) satellite, marking a significant advancement in global communications. This innovative use of 5G Non-Terrestrial Network (NTN) technology could transform connectivity for remote and underserved regions, enhancing emergency response coordination, rural healthcare, and industrial operations. The connection, maintained as the satellite traversed the sky, utilized Amarisoft's 5G technology and demonstrated the potential for reliable telehealth services, remote surgeries, and improved in-flight internet. ESA's Head of Telecom Systems, Alberto Ginesi, highlighted the importance of open standards developed by the 3GPP, suggesting that mobile devices may soon connect directly to satellites, reducing reliance on terrestrial infrastructure and fostering greater interconnectivity among service providers. This experiment paves the way for future projects like IRIS², promising a new era of mobile coverage.
Published: Dec 28 2024, 4 ameznews.inA new study suggests that the Earth may contain trillions of metric tons of natural hydrogen, potentially revolutionizing the energy landscape. Researchers, using modified geological models, estimate vast untapped reserves beneath the Earth's surface, with significant discoveries already made in Mali. While hydrogen is seen as a clean energy source, its extraction has been challenging, often relying on costly "green" hydrogen production methods. The study indicates that even a small fraction of the estimated hydrogen could meet global demand for the next 200 years, surpassing the energy potential of all proven natural gas reserves. However, uncertainties remain regarding the accessibility of these reserves and the actual presence of hydrogen, as some experts speculate it may have leaked over time. The findings, published in *Science Advances*, highlight the need for further research into this promising yet largely untested resource.
Published: Dec 25 2024, 4 ameznews.inResearchers have proposed a new theory regarding the construction of Stonehenge, suggesting it was built as a political statement to unify Neolithic Britain amid rising immigration from Europe. The study highlights the Altar Stone, sourced from northern Scotland, as a significant element in this narrative, emphasizing the monument's unique use of stones from hundreds of kilometers away, unlike other prehistoric sites that typically used local materials. This ambitious project aimed to forge a shared identity among diverse communities but ultimately failed, as the Indigenous population was replaced by incoming settlers by the time Stonehenge was completed. The findings, published in *Archaeology International*, indicate that the monument's construction coincided with a cultural upheaval, reflecting a response to a legitimacy crisis caused by the influx of new peoples. Professor Mike Parker Pearson noted that the similarities between Stonehenge and ancient Scottish structures suggest a deeper cultural connection.
Published: Dec 27 2024, 11 pmeznews.inResearchers at Caltech have quantified the speed of human thought, estimating it at just 10 bits of information per second, a stark contrast to the estimated 109 bits per second of sensory data processed by the brain. This study, published in the journal *Neuron*, highlights the paradox of our cognitive capabilities: while our senses absorb vast amounts of information, our conscious thought operates at a significantly slower pace. For instance, an advanced typist produces around 120 words per minute, translating to 10 bits per second when accounting for the predictability of language. The findings suggest that this slow processing speed may be sufficient for survival, as our ancestors thrived in environments where changes occurred at a manageable rate. The researchers emphasize that this disparity between sensory input and cognitive output raises intriguing questions about human cognition and the potential limitations for developing brain-computer interfaces.
Published: Dec 27 2024, 8 pmeznews.inIn the 1990s, Romanian-Australian economist Stefan Mandel devised a method to win the lottery repeatedly, achieving a remarkable 14 wins. His strategy involved purchasing every possible combination of numbers in certain lotteries where the jackpot exceeded the cost of buying all combinations. Initially successful in Romania, Mandel moved to Australia and later targeted the Virginia lottery, which had only 7,059,052 combinations. With a jackpot of $15.5 million, he coordinated a massive ticket purchase, acquiring 6.4 million combinations. Despite some logistical challenges and an investigation by the FBI and CIA, Mandel's approach was not deemed illegal. His winnings, amounting to millions, were shared with investors, allowing him to retire comfortably in Vanuatu. Mandel's story highlights the intersection of mathematics and strategy in gambling, demonstrating that while luck plays a role, calculated risk can yield significant rewards.
