China is poised to explore the Earth's mantle with its newly launched drilling ship, _Meng Xiang_, which translates to "dream." Officially entering service in November 2024, the vessel can drill up to 11 kilometers (6.8 miles) beneath the seabed, surpassing the capabilities of Japan's _Chikyū_ and the now-scrapped US ship _JOIDES Resolution_. Measuring 179.8 meters (589 feet), _Meng Xiang_ can operate independently for 120 days and supports a crew of 180, alongside nine laboratories focused on various scientific disciplines. This ambitious mission aims to unlock secrets of the Earth's interior, enhancing our understanding of plate tectonics and oceanic crust evolution. Xu Zhenqiang, director of the China Geological Survey, emphasized the potential for groundbreaking discoveries that could reshape our knowledge of geology and marine life. The project also signifies China's ascent as a scientific superpower, challenging the US's historical dominance in oceanic research. 
Published: Mar 14 2025, 9 pmeznews.inIn a groundbreaking study, scientists have inserted a human "language gene" variant into mice, revealing significant insights into the evolution of vocal communication. The modified mice exhibited distinct vocalization patterns, with higher-pitched squeaks and varied sound selections when calling for their mothers, compared to their unaltered counterparts. Notably, adult male mice produced more complex high-frequency calls when courting females. This research centers on the NOVA1 gene, which, while present in various animals, has a unique variant in humans that alters RNA binding related to vocalization. The findings suggest that this genetic change may have conferred advantages in communication, potentially influencing the evolutionary success of modern humans over Neanderthals and Denisovans, who lacked this variant. The study, published in *Nature Communications*, underscores the intricate relationship between genetics and the development of complex speech.
Published: Mar 14 2025, 1 ameznews.inWhen you close your eyes, you may notice swirling patterns and flashes of light, known as "phosphenes." These visual sensations occur even in darkness due to the ongoing activity of retinal cells, which generate weak internal signals that mimic light. Katrina Schmid, an Associate Professor at Queensland University of Technology, explains that the brain interprets these random signals as visual images, leading to the perception of colors and patterns that aren't actually present. While phosphenes are typically harmless, they can sometimes indicate underlying retinal issues or neurological conditions, particularly if the patterns change or become more pronounced. Applying pressure to the eyeball can also induce phosphenes, but caution is advised. If you experience persistent or altered visual disturbances, consulting a medical professional is recommended.

In related studies, reading science articles has been shown to help maintain mental acuity as people age, countering cognitive decline. Meanwhile, a global mission led by the Nippon Foundation has resulted in the discovery of 866 new marine species, including various types of sharks and corals, highlighting the rich biodiversity of Earth's oceans. Additionally, a historical examination of mercury's use as a medicinal treatment sheds light on its toxic effects, exemplified by the tragic case of poet John Keats, who may have suffered from the very "cures" intended to heal him. These developments underscore the ongoing exploration and understanding of both human health and the natural world.
Published: Mar 16 2025, 3 ameznews.inA promising oral vaccine against norovirus, known as VXA-G1.1-NN, has shown positive results in early clinical trials targeting older adults, who are particularly vulnerable to severe complications from the virus. Unlike traditional injections, this pill delivers a harmless viral vector carrying a norovirus protein directly to the small intestine, potentially enhancing immune responses at mucosal surfaces where the virus typically enters the body. The trial involved 65 participants aged 55 to 80, with results indicating a strong antibody response lasting up to 210 days and no serious adverse events reported. Given the challenges of norovirus transmission, particularly in communal settings, the development of this vaccine could significantly reduce outbreaks. Vaxart plans to initiate a Phase 1 trial for a second-generation vaccine pill, marking a hopeful advancement in combating this highly contagious infection. The findings were published in *Science Translational Medicine*.
Published: Mar 14 2025, 6 pmeznews.inA palaeontologist's appeal for dinosaur footprint-bearing rocks near Biloela, Australia, has yielded significant discoveries, including a remarkable collection of prints found in the foyer of Biloela State High School. Dr. Anthony Romilio from the University of Queensland noted that while Australia lacks dinosaur bones from before the mid-Jurassic, it is rich in earlier dinosaur footprints. Many prints were lost due to coal mining, but some were salvaged, including those at the school, which had been overlooked for two decades. The prints, which belong to small, plant-eating dinosaurs, were documented for educational purposes by a local geologist. Romilio and his team identified 66 prints from 47 individuals in a small area, creating casts and 3D scans for future research. Despite the missed educational opportunities, the excitement among former students and teachers may inspire a renewed interest in palaeontology. The findings are detailed in the journal *Historical Biology*.
Published: Mar 15 2025, 5 pmeznews.inThe Ħal Saflieni Hypogeum, a remarkable underground burial complex in Malta, spans 500 square meters and is a UNESCO World Heritage Site since 1980, recognized for its "Outstanding Universal Value." Discovered accidentally in 1902 when a stone mason breached its roof, much of the upper level was lost, but subsequent excavations revealed a three-level labyrinth of chambers and corridors carved from globigerina limestone, showcasing impressive craftsmanship. A 2020 study suggested the site was designed to enhance acoustic properties, potentially making it one of the earliest structures created with music in mind. The Hypogeum served as a cemetery for around 7,000 individuals from 4000 to 2500 BCE, though it may have originally functioned as a sanctuary. Among its artifacts is the enigmatic "Sleeping Lady" figurine, symbolizing life or death. The site reflects Malta's rich prehistoric heritage, linked to its unique limestone and strategic Mediterranean location.
Published: Mar 13 2025, 5 ameznews.inExperts are urging a revision of public health guidelines regarding slushy drinks after a study revealed that glycerol, a common additive in sugar-free versions, can pose serious health risks to young children. The research examined 21 cases of children who fell ill after consuming these beverages, with many experiencing glycerol intoxication syndrome, characterized by symptoms such as reduced consciousness and severe hypoglycemia. The median age of affected children was just 3.5 years, highlighting the vulnerability of younger kids to the ingredient's effects. While current recommendations advise against slushies for children under four, researchers suggest that guidelines should be based on weight rather than age, potentially raising the safe age threshold to eight years. The findings coincide with a rise in the popularity of sugar-free options, prompting calls for greater transparency regarding glycerol concentrations in slushies to protect children's health.
Published: Mar 13 2025, 12 ameznews.inThe trend known as "bed rotting," which involves spending an entire day in bed without engaging in productive activities, has gained popularity, particularly among Gen Z and women. Advocates argue that it serves as a valuable self-care practice, allowing individuals to recharge mentally and physically in a fast-paced world. Psychologists suggest that while occasional bed rotting can help alleviate stress and prevent burnout, it may also mask underlying mental health issues like depression or anxiety. Experts caution that excessive bed rotting can disrupt sleep patterns and lead to physical health problems, such as blood clots from inactivity. To mitigate these risks, they recommend balancing rest with activity and avoiding prolonged periods in bed. Ultimately, while a day of bed rotting can be beneficial, maintaining a healthy lifestyle requires a careful balance between rest and activity.
Published: Mar 14 2025, 5 ameznews.inA grey nurse shark pup named Archie has made history at SEA LIFE Sydney Aquarium, marking a significant milestone for both the facility and marine conservation efforts in Australia. Born during a routine check at the Shark Valley exhibit, Archie's arrival is particularly noteworthy as grey nurse sharks (_Carcharias taurus_) are critically endangered due to overfishing and habitat destruction. Ben Buchanan, Head of Curatorial at the aquarium, described the event as "incredibly rare," especially given the species' low reproductive rate, with females birthing only once every two years. Now four months old and measuring 74 centimeters, Archie has been moved to a special nursery pool for optimal growth and will eventually join the adult sharks, including his mother, Mary-Lou. His birth not only highlights the challenges facing grey nurse sharks but also offers hope for the species' future.
