eznews.inIn a groundbreaking study off Cape Cod, Massachusetts, scientists have documented the first known predation of a porbeagle shark, revealing a grim tale of survival in the ocean's depths. Researchers had tagged a pregnant female porbeagle shark, measuring 2.2 meters, to track her movements. However, after 158 days, her tag surfaced in Bermuda, indicating a sudden change in her diving patterns and temperature data, suggesting she had been consumed by a larger predator. The investigation pointed to either a great white or shortfin mako shark as the likely culprits, with evidence favoring the great white due to its consistent depth patterns. This predation event is particularly concerning as it not only eliminates a reproductive female but also her developing pups, highlighting a previously unrecognized threat to the porbeagle population, which already faces challenges due to its slow reproductive rate. The findings were published in *Frontiers in Marine Science*. 
Published: Dec 17 2025, 6 pmeznews.inAfrica is slowly undergoing a geological transformation that could eventually see part of East Africa break away, potentially forming a new ocean. This process is linked to the East African Rift System (EARS), a significant rift zone stretching across several countries, including Ethiopia, Kenya, and Tanzania. The African tectonic plate is gradually splitting into the smaller Somalian plate and the larger Nubian plate, moving apart at a rate of mere millimeters per year. While a crack in Kenya in 2018 sparked speculation about an imminent split, it was merely a localized manifestation of ongoing rifting. Over the next 5 to 10 million years, the EARS may lead to a dramatically altered landscape, with East Africa becoming isolated by a new sea. This slow but inevitable geological change is part of Earth's dynamic history, reminiscent of the ancient separation of South America and Africa.
Published: Dec 21 2025, 3 ameznews.inThe National Oceanic and Atmospheric Administration's Great Lakes Environmental Research Laboratory (GLERL) has confirmed the discovery of approximately 40 circular structures at the bottom of Lake Michigan, identified as sinkholes. These depressions, ranging from 91 to 183 meters in diameter, were first detected during a 2022 sonar survey and further examined in an August expedition. Located about 22.5 kilometers southeast of Sheboygan, the sinkholes likely formed due to geological processes involving the dissolution of limestone by groundwater. Similar sinkholes in Lake Huron have revealed ancient microbial communities, suggesting that Lake Michigan's sinkholes may also harbor unique life forms. Scientists are eager to study these structures further, as they could provide insights into early Earth conditions and the types of microorganisms that thrive in extreme environments.
Published: Dec 21 2025, 1 ameznews.inEight years ago, an interactive map captured public imagination by showing where one would emerge if they dug straight through the Earth, often landing in an ocean. While the idea is whimsical, the reality of such a feat is daunting. China is currently attempting to drill a 10,000-meter hole to explore Cretaceous rocks, but this will not surpass the Kola Superdeep Borehole in Russia, which reached 12,263 meters. The Kola project revealed unexpected wet rocks and challenged existing geological theories. However, both projects fall short of penetrating the Earth's lithosphere to reach the mantle, which varies in thickness from 6 to 100 kilometers. Drilling deeper presents extreme challenges, including immense pressure—over 1.1 trillion hPa—and temperatures exceeding 5,200 degrees Celsius. These conditions would likely destroy drilling equipment, making the prospect of digging through the Earth a near-impossible task.
Published: Dec 20 2025, 8 pmeznews.inThis week, significant discoveries in paleontology and space exploration have made headlines. A 120-million-year-old dinosaur trackway has unveiled the fastest Cretaceous theropod, capable of sprinting at approximately 45 kilometers per hour, akin to a professional cyclist. Meanwhile, the fossil known as "Little Foot," one of the most complete early hominin skeletons, may represent an unidentified human relative, challenging existing evolutionary classifications. In a notable shift for NASA, billionaire Jared Isaacman has been confirmed as the agency's new administrator, following a tumultuous nomination process. Additionally, a rare event was captured as astronomers observed a flash of light on the Moon, likely caused by a collision with an unidentified object. Lastly, astronauts shared their thoughts on the best fictional spaceships, highlighting the enduring fascination with space travel in popular culture.
Published: Dec 20 2025, 10 pmeznews.inTuberculosis (TB) has reclaimed its position as the deadliest infectious disease globally, according to a new World Health Organization (WHO) report. In 2023, TB caused 1.25 million deaths, significantly surpassing the 320,000 fatalities attributed to COVID-19. The report highlights that 10.8 million people fell ill with TB last year, a slight increase from 2022, with 87% of cases concentrated in just 30 countries, particularly India, Indonesia, China, the Philippines, and Pakistan. Despite being preventable and treatable in 85% of cases, TB remains a major health crisis, with WHO calling for urgent action to eliminate the epidemic by 2030. While TB-related deaths have generally declined since 2021, funding for prevention and research remains critically low, with only $5.7 billion allocated last year against a target of $22 billion. WHO Director-General Dr. Tedros Adhanom Ghebreyesus emphasized the need for countries to fulfill their commitments to combat TB effectively.
Published: Dec 20 2025, 11 pmeznews.inSt. Augustine, located in northeastern Florida, holds the title of the oldest continuously inhabited city in the United States, founded in 1565 by Spanish explorer Pedro Menéndez de Avilés. This predates the establishment of Roanoke and Jamestown by 20 and 42 years, respectively, marking a significant chapter in American history often overshadowed by English narratives. Menéndez's expedition aimed to establish a Spanish settlement and displace a French fort nearby, leading to the city's founding on August 28, the feast day of Saint Augustine, after whom the city is named. Over the centuries, St. Augustine has transitioned through British and Spanish rule before becoming part of the United States, yet it has remained continuously settled. The city's rich history reflects the diverse European influences that shaped early American settlements, challenging the dominant English-centric historical perspective.
Published: Dec 20 2025, 8 pmeznews.inDiscovered just five and a half months ago, interstellar comet 3I/ATLAS has captivated scientists and the public alike, being only the third known interstellar object in our Solar System. Recent studies have highlighted its non-gravitational acceleration, a phenomenon often misinterpreted as evidence of artificial propulsion, such as a spacecraft engine. In reality, this acceleration results from outgassing—when the comet's icy core sublimates as it approaches the Sun, releasing jets of gas and dust that alter its trajectory. Researchers have measured this acceleration at approximately half a micron per second squared, a minor deviation that nonetheless provides insights into the comet's mass, estimated at 44 million metric tons before its solar encounter. This suggests that 3I/ATLAS's nucleus may be smaller than previously thought, measuring around 375 meters (1,230 feet). The findings were published in the journal Research Notes of the American Astronomical Society.
Published: Dec 16 2025, 9 pmeznews.inHumanity's capacity for significant change, both positive and negative, is evident in various contexts, from the climate crisis to the successful eradication of smallpox. A recent study has revealed that our activities, particularly the use of very low frequency (VLF) radio waves, have inadvertently influenced the Earth's radiation belts, known as the Van Allen belts. These belts, discovered in the 1950s, act as a protective shield against harmful cosmic rays and solar winds. Research from NASA's Van Allen Probes, which concluded in 2019, indicates that VLF signals, used in submarine communications, can alter the motion of charged particles in space, effectively creating a barrier that pushes these particles away. This phenomenon has led to the inner edge of the radiation belts shifting outward, suggesting potential applications for VLF technology in protecting Earth from solar storm particles.
Published: Dec 20 2025, 9 pmeznews.inA recent study published in the journal *Sexologies* has identified the missionary position, enhanced by a pillow under the woman's pelvis, as the most effective for heterosexual women seeking orgasm. Conducted by researchers at New H Medical in New York, the study assessed clitoral blood flow across five sexual positions, including variations of face-to-face and kneeling/rear entry. While blood flow increased in all positions except for kneeling/rear entry, the missionary position with a pillow proved most successful. However, the study's limitations are notable; it involved only one heterosexual couple, both medical professionals, which raises questions about the generalizability of the findings. Additionally, the research focused solely on blood flow as an indicator of arousal, rather than directly measuring orgasm. Previous studies have echoed these findings, suggesting a preference for face-to-face positions among larger populations.
