eznews.inBetelgeuse, the prominent red supergiant star, is expected to undergo a spectacular supernova explosion, potentially shining as brightly as the Moon for two weeks and remaining visible during the day for up to a year. While the exact timing of this event remains uncertain, recent observations have revealed fluctuations in its brightness, leading scientists to speculate that it could occur within a few decades. A significant breakthrough has come from a study utilizing data from NASA's Hubble Space Telescope, which suggests that Betelgeuse may have a companion star, named Siwarha, orbiting within its atmosphere. This companion star appears to create a "wake" in Betelgeuse's atmosphere, explaining its periodic dimming every 2,100 days. The findings provide crucial insights into the behavior of massive stars and their evolution, as astronomers prepare for further observations when Siwarha becomes visible in 2027. 
Published: Jan 06 2026, 10 pmeznews.inA recent fossil discovery in Mongolia has revealed the fastest theropod trackway from the Cretaceous period, with a medium-sized dinosaur estimated to have sprinted at approximately 45 kilometers (28 miles) per hour, comparable to a professional cyclist. The trackway, dating back 130 to 120 million years, consists of two isolated sets of footprints attributed to a large theropod, _Chapus lockleyi_, and an unidentified medium-sized dinosaur from the Eubrontidae family. Researchers determined the dinosaur's speed by analyzing its stride length relative to its hip height, yielding a remarkable score of 5.25, indicative of a running gait. The straightness of the trackway and deep toe impressions further support the conclusion of a high-speed run. This finding enhances our understanding of theropod locomotion and underscores the capabilities of smaller and mid-sized dinosaurs, as detailed in a study published in *Science China Earth Sciences*.

A baggage handler at Dublin Airport explained that these ribbons can obstruct the scanning process, leading to potential misplacement of bags. If a suitcase cannot be scanned automatically due to the interference, it may require manual processing, increasing the risk of it not making the flight. Additionally, travelers are urged to remove old stickers and tags, which can also confuse scanners. In a further tip, the handler cautioned against packing marzipan, as its density resembles that of certain explosives, potentially triggering security alarms. These insights highlight the often-overlooked details that can impact the travel experience, reminding passengers to be mindful of their luggage preparation.
Published: Jan 06 2026, 9 ameznews.inThe title of the world's largest rock is contested, primarily between Uluru and Mount Augustus in Australia. Uluru, or Ayers Rock, is a sandstone monolith that rises 348 meters (1,142 feet) and spans 9.4 kilometers (5.8 miles) around its base, making it an iconic feature of Central Australia. Formed around 550 million years ago from seabed deposits, it has been sculpted by natural elements over millennia. In contrast, Mount Augustus, located over 1,000 kilometers (620 miles) north of Perth, is technically a monocline, standing 860 meters (2,820 feet) tall and covering 4,795 hectares (11,850 acres), making it larger in area but geologically distinct. While Uluru is a uniform mass of rock, Mount Augustus consists of multiple folded layers. Additionally, the largest freestanding boulder in the world, Giant Rock in California, measures 5,800 square feet and has a unique cultural history.
Published: Jan 06 2026, 12 pmeznews.inNew research has revealed that female European common frogs (_Rana temporaria_) employ several strategies to avoid unwanted mating during the spring's explosive breeding season. Traditionally viewed as passive participants, these females exhibit three key avoidance behaviors: rotation, release calls, and tonic immobility, or feigning death. The study, led by Dr. Carolin Dittrich from the Natural History Museum of Berlin, found that smaller females were more adept at escaping male advances, with 83% using rotation and nearly half employing release calls to trick males into letting go. Tonic immobility was observed in 33% of females during mating attempts. These tactics may not only serve to evade mating but could also indicate the strength of potential mates, suggesting a complex interplay between stress responses and reproductive strategies. The findings challenge previous assumptions about female passivity in frog mating behaviors and highlight the need for further research into their stress levels and natural behaviors.
Published: Jan 06 2026, 1 pmeznews.inFor the first time, astronomers have successfully measured the mass and distance of a solitary "rogue" planet, designated KMT-2024-BLG-0792/OGLE-2024-BLG-0516, located approximately 9,785 light-years from Earth. This breakthrough was achieved through simultaneous observations from ground-based telescopes and the now-retired Gaia space telescope, overcoming the challenge of mass-distance degeneracy that complicates such measurements. The planet, estimated to be about 22% the mass of Jupiter, likely formed in a proto-planetary disk before being ejected into interstellar space. Rogue planets, which are not bound to any star, are difficult to detect due to their cold nature and lack of visible light. The findings, published in the journal Science, pave the way for future observations, particularly with the upcoming Nancy Grace Roman Telescope, which is expected to identify hundreds of free-floating exoplanets, enhancing our understanding of these elusive worlds.
Published: Jan 06 2026, 3 ameznews.inA groundbreaking discovery of enormous shark fossils in northern Australia has reshaped our understanding of the evolution of these apex predators. Previously believed to have first emerged around 100 million years ago in North America and Europe, new research indicates that gigantic lamniform sharks actually originated approximately 115 million years ago in the Southern Hemisphere. The fossils, found in the Darwin Formation, include vertebrae from a massive Cardabiodontid shark, estimated to measure between 6 to 8 meters and weigh over 3 tons. This suggests that these early sharks occupied top predator roles alongside marine reptiles like *Kronosaurus*. The findings challenge long-held beliefs about the evolutionary timeline of lamniform sharks and highlight their significant presence in ancient marine ecosystems. The study, published in *Communications Biology*, underscores the importance of Australia in the history of these formidable creatures.
Published: Jan 01 2026, 8 pmeznews.inSaltwater crocodiles, the largest living reptiles with the strongest bite force of any animal, have long puzzled researchers regarding their ability to traverse vast distances across the South Pacific. A study conducted by a team from the University of Queensland, which included the late Steve Irwin, tracked 27 adult crocodiles using sonar transmitters over a year, yielding 1.2 million data points. The findings revealed that these crocodiles exploit changing tides to "surf" ocean currents, allowing them to travel significant distances—over 590 kilometers (367 miles) in some cases—by resting on riverbanks during low tides. This behavior not only explains their successful colonization of numerous islands but also suggests that crocodilians may have historically crossed major marine barriers. Notably, one crocodile journeyed 590 kilometers in 25 days, demonstrating their remarkable adaptability despite being poor swimmers.
Published: Jan 01 2026, 8 ameznews.inResearchers have uncovered a cave in Spain, known as Des-Cubierta, that appears to have held ritual significance for Neanderthals, who repeatedly returned to stash horned animal skulls over generations. The site contains 35 crania from species such as aurochs and steppe rhinoceroses, alongside Neanderthal teeth and stone tools, indicating a symbolic function for the skulls, possibly as trophies or ritual items. Although attempts to date the skulls have been unsuccessful, uranium-series dating of charcoal suggests they were collected between 135,000 and 50,000 years ago. The skulls are dispersed within several meters of sediment, indicating a prolonged practice rather than a single event. Researchers emphasize that this behavior reflects a culturally motivated tradition among Neanderthals, although the exact purpose of the skull collection remains uncertain. The findings are detailed in the journal *Archaeological and Anthropological Sciences*.
Published: Jan 06 2026, 5 ameznews.inAround 3,200 years ago, the Eastern Mediterranean, North Africa, and Near East thrived with interconnected civilizations, marked by advancements in trade, culture, and technology during the Bronze Age. However, this prosperity abruptly ended in the 12th century BCE, leading to what is known as the "Bronze Age Collapse." Major societies, including the Assyrian Empire, New Kingdom of Egypt, and Mycenaeans, faced a period of stagnation and decline, characterized by wars, rebellions, and the loss of writing systems. Various theories have emerged to explain this collapse, including invasions by the enigmatic "Sea Peoples," internal political instability, and environmental changes that caused droughts and food shortages. Archaeologist Eric Cline suggests that a combination of these factors created a "perfect storm" of calamities, illustrating that even the most advanced civilizations are vulnerable to collapse.
