A viral claim on social media suggests that individuals with rhesus-negative blood may be descendants of aliens, a theory popularized by a TikTok video featuring a clip from the 2009 series *Ancient Aliens*. Proponents argue that extraterrestrial intervention could explain the rarity of this blood type, which is found in only about 15% of the global population. While the origins of rhesus-negative blood remain unclear, scientists have not found evidence supporting the alien theory, which is often framed as part of the "Aliens of the Gaps" argument. Instead, genetic mutations and natural selection are more plausible explanations for its existence. Historical context reveals that the Rh factor was identified in the 1930s, and while some speculate about its potential health implications, such as resistance to certain parasites, no definitive benefits have been established. Ultimately, the notion of alien ancestry lacks scientific backing and is overshadowed by more rational genetic explanations. 
Published: Mar 17 2025, 5 ameznews.inA recent meta-analysis of over 100 studies has debunked the long-held myth that women's cognitive abilities fluctuate during their menstrual cycle. Despite common beliefs suggesting that menstruation impairs mental performance, the research found no consistent evidence supporting this notion. The study, published in PLOS One, highlights that while hormonal changes occur throughout the cycle, they do not significantly impact cognitive functions such as attention, creativity, and intelligence. Some minor differences in memory and spatial abilities were noted, but these were deemed non-robust and likely specific to the studied groups. The authors emphasize the need for further research to address existing gaps in understanding menstruation's effects on cognition, as many questions remain unanswered. Ultimately, the findings suggest that any cognitive changes related to the menstrual cycle are negligible, challenging societal perceptions of menstruation as a debilitating condition.
Published: Mar 19 2025, 2 ameznews.inA striking video from Hormuz Island, Iran, has gone viral, showing rain cascading down a cliff and turning the beach and sea below a vivid blood red. The footage, shared by a local tour guide, highlights the island's aptly named Red Beach, attracting over a million likes on Instagram. The phenomenon is not due to "blood rain" or divine displeasure, but rather the result of the island's unique geological composition. Hormuz Island, known as "rainbow island" for its colorful mineral deposits, features a salt dome that contains layers of red soil rich in hematite and iron hydroxides. When it rains, this soil interacts with water, creating the striking red hue. While the soil is mined for various uses, including cosmetics and food, its heavy metal content raises health concerns. Locals, however, incorporate the soil, known as 'Gelak', into traditional dishes, including a local bread called 'tomshi'.
Published: Mar 18 2025, 11 pmeznews.inBeneath Colorado's Cheyenne Mountain lies a fortified settlement designed to withstand catastrophic events, including nuclear, electromagnetic, and biological attacks. Constructed during the Cold War, the Cheyenne Mountain Complex is one of the United States' most secure military installations, buried under 760 meters of granite. Its impressive 23-ton blast doors can endure impacts from a 30-megaton nuclear bomb, such as the B41, but would likely falter against the 50-megaton Tsar Bomb, the most powerful nuclear weapon ever tested. The facility, which has been operational since April 20, 1966, houses military and civilian operations, including air and space surveillance and missile defense. The complex's doors were sealed on September 11, 2001, and will close again in response to serious threats, ensuring the safety of approximately 300 personnel inside. The Cheyenne Mountain Complex remains a critical hub for coordinating military responses in times of crisis.
Published: Mar 19 2025, 12 ameznews.inA recent study has revealed that nomadic tribes in Central Asia, around 2,000 years ago, utilized diamond drills to create intricate jewelry from semi-precious stones. Researchers analyzed 51 stone beads from the Rabat Cemetery in Uzbekistan, dating from the second century BCE to the first century CE, which were part of the Yuezhi culture. Notably, 41 of these beads exhibited markings indicative of diamond drilling techniques, suggesting a sophisticated understanding of the material. The study found that ancient jewelers employed both single and double diamond drills to perforate the beads, which were likely passed down through generations. This evidence challenges previous assumptions that the beads were imported from the Indus Valley, indicating instead that diamond drilling techniques were locally developed in Bactria. The findings underscore the widespread use of diamond drilling across southern and central Asia long before the technology was documented elsewhere. The research is published in *Archaeological and Anthropological Sciences*.
Published: Mar 18 2025, 9 pmeznews.inAs the spring equinox approaches on March 20, skywatchers may have another opportunity to witness stunning aurora displays, thanks to the Russell-McPherron effect. This phenomenon, which peaks during the equinoxes, occurs when the magnetic fields of the Earth and Sun align in opposite directions, enhancing the capture of charged particles from the solar wind that create auroras. Geophysicist Dr. Ciaran Beggan explains that this alignment maximizes the interaction between the solar wind and Earth's magnetic field, leading to increased geomagnetic activity. This year, the potential for spectacular auroras is heightened by the current solar maximum, a phase in the Sun's 11-year cycle characterized by heightened solar activity, including sunspots and solar flares. If significant solar events coincide with the equinox, observers could be treated to an even more impressive display than last year's, when auroras were seen much farther south than usual.
Published: Mar 18 2025, 6 pmeznews.inTwo independent research teams have found that Uranus emits more internal heat than previously recorded by Voyager 2, suggesting it generates some of its own heat rather than solely reflecting sunlight. The findings, which are pending peer review, align Uranus more closely with other gas giants, challenging earlier assumptions that it lacked significant radioactive isotopes. Using data from the Hubble Space Telescope and other advanced instruments, the teams estimated excess heat emissions of 12.5% and 15%, respectively, although both figures are still significantly lower than those of Neptune, Jupiter, and Saturn. The discrepancy may stem from Voyager 2's timing during Uranus's equinox, leading to potential miscalculations. Despite these revelations, Uranus remains an outlier among gas giants, with its unusual axial tilt contributing to seasonal heat variations. Future missions, such as a proposed flagship mission, could provide further insights, though funding and timing remain uncertain.

Published: Mar 18 2025, 8 pmeznews.inPalaeontologists have made a groundbreaking discovery in Morocco, unearthing the world's oldest known cerapodan dinosaur, identified by a distinctive femur dating back approximately 168 million years. This find, located in the El Mers III Formation, is significant as it sheds light on the early evolution of cerapodans, small, plant-eating dinosaurs that later spread globally during the Cretaceous. Prior to this, evidence of ornithopod evolution was limited to fossilized trackways, but this femur represents the oldest body fossil of its kind, surpassing the previous record holder from Leeds, England, by two million years. Dr. Susannah Maidment from the Natural History Museum emphasized the importance of the femur's unique anatomical features, which confirm the diversification of these dinosaurs during the Middle Jurassic. The discovery highlights Morocco as a vital site for further exploration of this period in dinosaur history, with the El Mers III Formation also yielding other ancient species.
Published: Mar 18 2025, 4 pmeznews.inArtificial intelligence (AI) has made significant strides in image and text generation over the past decade, yet it still struggles with basic tasks such as reading analog clocks and understanding calendars. A recent study from the University of Edinburgh tested seven AI models on time-related questions, revealing that they correctly identified the time from images of clocks less than 25% of the time, particularly faltering with Roman numerals and stylized hands. For calendar tasks, the models performed slightly better, but still made errors around 20% of the time. The researchers noted that while AI excels in complex reasoning, it often fails at simpler, everyday tasks, highlighting a critical gap in its capabilities. Co-author Aryo Gema emphasized the need to address these fundamental issues to ensure AI can be effectively integrated into time-sensitive real-world applications. The study is currently available on the pre-print server arXiv.
Published: Mar 18 2025, 8 pmeznews.inThe question of whether zero is an odd or even number often confuses many due to its unique properties on the number line. Mathematically, zero is classified as an even number because it can be divided by two without leaving a remainder; specifically, 0 equals 0 times 2. This classification is supported by the definition of even numbers, which are multiples of two. Additionally, zero exhibits peculiar behaviors in mathematics, such as the fact that multiplying any number by zero results in zero, while dividing by zero leads to undefined outcomes. Despite its idiosyncratic nature, zero's status as an even number is clear, as it fits the criteria of being divisible by two. Thus, while zero may seem unusual, it is definitively not odd.
