Sharks, often misunderstood as fearsome predators, play a crucial role in marine ecosystems and have recently been confirmed as adherents to the "two-thirds scaling law," a mathematical principle that describes how an animal's volume scales with its surface area. A study led by Joel Gayford at James Cook University analyzed 54 shark species, revealing that their surface area-to-volume ratios closely align with the expected coefficient of 0.66, deviating only slightly. This finding is significant as it enhances our understanding of how sharks and other large animals regulate body temperature and oxygen use, which is vital in the context of climate change. The research suggests that sharks have evolved to maintain this ratio, potentially due to the energetic costs associated with deviating from it. This insight not only aids in shark conservation efforts but also opens avenues for applying similar methodologies to other species, reinforcing the fundamental nature of this mathematical principle in biology. 
Published: Jul 13 2025, 10 pmeznews.inAfter over 40 years of excavations at the ancient Maya city of Caracol in Belize, researchers have discovered the tomb of Te K’ab Chaak, the first king and founder of its royal dynasty. Diane Z. Chase from the University of Houston, who has led the excavations since 1985, emphasized the significance of this find, as it aligns with hieroglyphic records identifying him as a ruler. The tomb, dated around 350 CE, contained a wealth of artifacts, including a jadeite death mask and earflares, and was located at the base of a royal family shrine. This discovery suggests that Te K’ab Chaak may have established diplomatic ties with the distant city of Teotihuacan earlier than previously thought, challenging existing historical timelines. Researchers plan to conduct further analyses on his remains to gain deeper insights into this pivotal figure in Maya history.
Published: Jul 11 2025, 7 pmeznews.inNASA's Parker Solar Probe has uncovered evidence of a "helicity barrier" in the Sun's atmosphere, potentially shedding light on the long-standing "coronal heating problem." Launched in 2018, the probe has made multiple close approaches to the Sun, reaching speeds of 692,000 kilometers per hour. The mystery lies in the Sun's corona, which is significantly hotter than its surface, with temperatures soaring to 3.5 million °F (2 million °C). Previous theories, including turbulence and magnetic waves, struggled to explain this phenomenon. The helicity barrier may act as a dam, redirecting energy into ion cyclotron waves and linking these theories. Researchers analyzed solar wind magnetic field data, confirming the barrier's presence under specific conditions. This breakthrough could enhance our understanding of solar wind acceleration and turbulent dissipation, with implications for astrophysics beyond our solar system. The findings are detailed in a study published in *Physical Review X*.
Published: Jul 10 2025, 1 ameznews.inAs you settle in for the night, consider the fate of two ancient human relatives, _Homo habilis_, who lived in East Africa around 1.8 million years ago. These early hominins, known for their tool-making skills, met a gruesome end, with their remains revealing they were likely attacked by a crocodile and a leopard-like carnivore. Discovered in the Olduvai Gorge, the fossils known as OH 8 and OH 35 show evidence of limbs being torn off and bite marks consistent with predation. While there is debate over whether OH 8 and another specimen, OH 7, represent the same individual, both exhibit signs of having been consumed by these formidable predators. This stark reminder of the harsh realities faced by ancient hominins underscores the relentless challenges posed by nature, highlighting our shared evolutionary history and the brutal forces that shaped it.
Published: Jul 11 2025, 10 pmeznews.inThe "Dead Internet Theory" posits that the internet, as we know it, has become a desolate space dominated by artificial intelligence-generated content since around 2016 or 2017. Proponents argue that the online landscape feels sterile and devoid of genuine human interaction, likening it to a "hot air balloon with nothing inside." They claim a coordinated effort exists to manipulate public discourse through bots and paid content creators, distracting users from questioning societal elites. While it's true that bot activity constituted nearly half of all internet traffic in 2022, experts like Karl Triebes warn that the rise of generative AI will exacerbate this issue. Despite concerns over declining content quality, particularly in search engines like Google, the majority of online content is still human-generated. Ultimately, while the theory highlights real issues, it exaggerates the extent of the internet's decline, which remains vibrant and active.
Published: Jul 09 2025, 2 pmeznews.inA proposed mission, led by the UK, aims to deploy a mini-fridge-sized radio telescope, known as CosmoCube, to the far side of the Moon to investigate the "Cosmic Dark Ages," a period approximately 380,000 years after the Big Bang when the universe was devoid of stars and galaxies. This era, lasting about 100 million years, remains largely unexplored due to the challenges of detecting radio waves emitted by hydrogen, the universe's most abundant element. The Moon's far side offers a pristine radio environment, shielded from Earth's interference, making it an ideal location for such observations. Dr. Eloy de Lera Acedo from the University of Cambridge emphasized the mission's potential to unlock mysteries surrounding the transition from darkness to the formation of stars and galaxies. The initiative is part of the European Space Agency's mini-fast mission program, with a budget cap of €50 million and a projected timeline of five years.
Published: Jul 10 2025, 1 pmeznews.inThe Shroud of Turin, a controversial linen cloth believed by some to be the burial shroud of Jesus Christ, has recently garnered renewed media attention following a 2022 study by Italian scientist Liberato De Caro. This research suggests the Shroud may date back to the time of Jesus, contradicting previous radiocarbon dating that placed its origin between 1260 and 1390 CE. De Caro's team employed a novel technique, wide-angle X-ray scattering, to analyze the Shroud's fibers, claiming that its cellulose has aged slowly due to the cooler conditions in which it has been stored. However, the study's findings are met with caution, as past research by De Caro faced scrutiny and retraction due to methodological concerns. Experts emphasize that further investigation is necessary to validate these claims before drawing definitive conclusions about the Shroud's authenticity and age.
Published: Jul 13 2025, 6 pmeznews.inIn a groundbreaking mission in 2022, NASA successfully redirected the asteroid Dimorphos by crashing its DART spacecraft into it, demonstrating the feasibility of altering the trajectory of celestial objects. The impact not only changed Dimorphos's orbit by 32 minutes but also ejected boulders ranging from 0.2 to 3.6 meters in size, which were propelled at speeds of up to 52 meters per second. A recent study revealed that these boulders were not scattered randomly; instead, they formed distinct clusters, suggesting complex dynamics at play. The largest cluster, likely composed of fragments from two large boulders, carried more momentum than the spacecraft itself, potentially tilting Dimorphos's orbital plane. This unexpected behavior complicates future asteroid deflection strategies, highlighting the need for a comprehensive understanding of debris dynamics. The European Space Agency's Hera mission, set to arrive in 2026, aims to further investigate these findings.
Published: Jul 09 2025, 10 pmeznews.inConcerns about a potential civil war in the United States have been a topic of discussion among political commentators, yet a recent study reveals that most Americans do not foresee such a conflict. Research led by Garen J. Wintemute at the University of California, Davis, indicates a decline in the belief that civil war is imminent, dropping from 13.7% in 2022 to just 6.5% in 2024. While some subgroups, particularly MAGA Republicans and those with extremist views, show higher levels of support for the idea of civil war, overall sentiment remains largely against it. The study, which surveyed over 8,800 participants, found that 84% would not engage in a conflict, and only 3.7% felt likely to participate as combatants. Experts suggest that while a full-scale civil war is improbable, sporadic political violence may occur, emphasizing the importance of community dialogue to counteract calls for violence.
Published: Jul 10 2025, 10 pmeznews.inIn a surprising revival of a quirky behavior, orcas have been spotted once again donning dead salmon on their heads after a 37-year hiatus. This trend, which first emerged in 1987 when a female orca in Puget Sound began the unusual practice, has resurfaced among members of the J pod in October 2024. Observers suggest that the orcas may be using their heads as storage for excess salmon, capitalizing on the current abundance of the fish. While this playful behavior is endearing, orcas are also known for more destructive tendencies, such as attacking boat rudders and harassing porpoises without consuming them. Experts note that these cultural fads can vary among different orca populations and often fade over time, leaving researchers uncertain about the longevity of this latest salmon hat trend.
