Rhnull, or "golden blood," is an extraordinarily rare blood type, with fewer than 50 known cases worldwide. Identified first in 1961 in an Indigenous Australian woman, Rhnull lacks all Rh antigens due to mutations in the _RHCE_ gene, making it invaluable for transfusions among individuals with rare blood types. While it is considered universal for those with Rh-related blood types, finding a compatible donor can be challenging, as any other blood type contains Rh antigens that could trigger an immune response. This blood type is also linked to health complications, as the absence of Rh proteins can lead to structural abnormalities in red blood cells, making them prone to rupture. Despite its rarity, Rhnull has significant potential in biomedical research, particularly in developing treatments for conditions like Rhesus Disease, where maternal antibodies attack fetal blood cells. 
Published: Mar 14 2025, 11 pmeznews.inGoogle, the world's second most popular website, can be a double-edged sword, offering valuable information while also leading users to unsettling content. A recent discussion highlights several terms that should be avoided in searches due to their disturbing implications. For instance, "oral myiasis" refers to a condition where insect larvae invade the mouth, often resulting in a foul odor, as documented in medical literature. Another alarming term is "degloving," which describes a severe injury where skin is removed from the underlying tissue, often illustrated with graphic images to deter risky behavior. Additionally, "krokodil," an opioid known for causing severe skin damage, and "Fournier's gangrene," a life-threatening infection affecting the genitals, are also cautioned against. Other terms, such as "harlequin ichthyosis," a rare genetic skin disorder, further emphasize the need for caution when using search engines for sensitive health topics.
Published: Mar 15 2025, 4 ameznews.inThe largest animal ever to exist on Earth, the blue whale, currently swims in our oceans, dwarfing even the largest land mammals like elephants. While mammals did grow larger after the extinction of dinosaurs, filling ecological niches left vacant, they are unlikely to reach the colossal sizes of creatures like the Brachiosaurus. Research by University of Georgia's John Gittleman indicates that various mammal lineages evolved to similar maximum sizes due to shared ecological roles. Among the largest land mammals was Paraceratherium, an ancient rhinoceros ancestor weighing up to 20 tonnes. However, biological constraints limit mammalian size; as endotherms, mammals expend significantly more energy to maintain body temperature compared to ectothermic dinosaurs. Consequently, while the conditions for giant mammals might exist, their biology restricts them from achieving the sizes of the largest dinosaurs, leaving the door open for reptiles, like lizards, to potentially evolve larger forms.
Published: Mar 11 2025, 5 pmeznews.inIn late October 79 CE, the ancient Roman town of Pompeii faced its catastrophic fate as Mount Vesuvius erupted, engulfing the area in a deadly cloud of superheated gas, molten rock, and ash. Today, Pompeii attracts around 2.5 million tourists annually, drawn by the haunting plaster casts of its victims, often misrepresented as petrified bodies. However, these casts are not actual remains but rather replicas created from voids left in the volcanic ash where bodies once lay. This technique, pioneered in the 1860s by archaeologist Giuseppe Fiorelli, involves pouring plaster into these cavities to form exact imprints of the deceased. Modern methods, including X-ray techniques, have refined this process, but the essence remains the same. Despite the destruction from World War II, the casts continue to evoke the tragedy of Pompeii, illustrating the collaboration between ancient and modern efforts in preserving this historical site.
Published: Mar 15 2025, 2 ameznews.inThe Grand Canyon, shaped by the Colorado River over millions of years, currently holds a staggering volume of approximately 4.17 trillion cubic meters, equating to around 4.17 quadrillion liters of water, according to the National Park Service. This immense capacity raises a whimsical question: how long would it take to fill the canyon with liquid? Inspired by a viral video, a thought experiment reveals that if all 8 billion people on Earth contributed their daily urine output of about 1.89 liters, it would take nearly 800,000 years to fill the canyon. While the idea of filling the Grand Canyon with various liquids—be it beer, orange juice, or even whale milk—remains purely hypothetical, it highlights the canyon's vastness and the abundance of water on Earth, estimated at 1.386 billion cubic kilometers. However, the article emphasizes the importance of respecting natural wonders like the Grand Canyon.
Published: Mar 14 2025, 11 pmeznews.inA recent study from the Johns Hopkins Bloomberg School of Public Health highlights the growing concern over ultra-processed foods (UPFs), which account for over half of the calories consumed in US homes. UPFs include not only fast food and snacks but also items like infant formula and store-bought bread, characterized by numerous additives. The study aimed to assess the feasibility of a behavioral intervention to reduce UPF intake among 14 overweight or obese participants, who attended weekly meetings focused on meal planning and mindfulness. Over eight weeks, participants reported an average weight loss of 3.5 kilograms and a reduction in daily calorie intake. While the results indicate potential benefits, the small sample size and self-reported data limit generalizability. The authors emphasize the need for broader public health policies alongside individual interventions to effectively tackle UPF consumption in the long term. The findings are published in the journal Obesity Science and Practice.
Published: Mar 14 2025, 11 pmeznews.inIn March 2013, a tragic incident unfolded in Seffner, Florida, when 37-year-old Jeff Bush was swallowed by a sinkhole that opened beneath his bedroom. The sinkhole, approximately 6 meters (20 feet) wide and deep, was heard by his brother Jeremy and his partner Rachel, who rushed to the scene after hearing Jeff's screams. Despite Jeremy's desperate attempt to rescue him, he was pulled to safety by a deputy sheriff as the ground continued to collapse. Rescuers were unable to locate Bush's body, which, along with bedroom furniture, was lost in the sinkhole. The following day, engineers deemed the site too dangerous for further rescue efforts, leading to the demolition of the house and filling of the sinkhole with gravel. Florida's geology, rich in limestone, makes it particularly prone to such sinkholes, which occur when underground caverns collapse.
Published: Mar 15 2025, 12 ameznews.inA team of researchers from Graubuenden University of Applied Sciences in Switzerland has set a new world record by calculating the mathematical constant pi to an astonishing 62.8 trillion digits, surpassing previous records held by Google and Timothy Mullican. The calculation, which took 108 days and nine hours, was performed using a high-performance supercomputer at the Center for Data Analytics, Visualization and Simulation (DAViS), achieving results 3.5 times faster than earlier attempts. To print all the digits would require nearly 35 billion sheets of A4 paper, weighing about 52% of the Empire State Building and stretching over 10 million kilometers. Project leaders emphasized that the endeavor not only demonstrated advanced computational capabilities but also highlighted areas for improvement in their infrastructure. The last ten digits of pi from this record are 7817924264, although the achievement is pending certification by the Guinness Book of Records.
Published: Mar 14 2025, 10 pmeznews.inThe discovery of _Proteroctopus ribeti_, a 165-million-year-old fossil cephalopod found in France's La Voulte-sur-Rhône Lagerstätte, has significantly advanced our understanding of octopus evolution. Initially described in 1982, this well-preserved specimen has revealed that it is a basal member of Vampyropoda, challenging previous assumptions about its classification. A 2016 study utilizing synchrotron X-ray microtomography uncovered unexpected features, including two rows of suckers on its arms—previously thought to have evolved later—and the absence of an ink sac, suggesting a different evolutionary path. Additionally, _Proteroctopus_ possessed a poorly mineralized gladius and an axial nerve in its arms, indicating a transitional form between squid-like ancestors and modern octopuses. While not the oldest octopus fossil, _Proteroctopus_ remains crucial for understanding the evolutionary history of cephalopods, as soft-bodied organisms are rarely fossilized due to their delicate structures.
Published: Mar 14 2025, 9 pmeznews.inSixty-six million years ago, a 12-kilometer asteroid struck Earth, creating the Chicxulub crater in Mexico and triggering a mass extinction event, including the demise of the dinosaurs. The impact generated an earthquake exceeding magnitude 11 and produced Rayleigh waves that caused significant geological disruption in the Gulf of Mexico. Recent research led by Dr. Gary Kinsland from the University of Louisiana at Lafayette has revealed extensive "megaripples" of sediment, formed by the tsunami generated by the impact, which extend further than previously thought. These megaripples, reaching heights of 16 meters and spaced 600 meters apart, were found in fluidized marl muds, suggesting that the tsunami's high-velocity flow shaped the sediment into these formations. While the study highlights the profound effects of the Chicxulub impact, further investigation is needed to fully understand the mechanisms behind the formation of these large sediment structures. The findings are detailed in the journal Marine Geology.
