eznews.inAround 5 billion years ago, our Sun ignited by converting hydrogen into helium, surrounded by a disk of material that included hydrogen and complex molecules. This chaotic environment led to the formation of planets, with Jupiter emerging as the first, likely within the first 3 million years, boasting a mass equivalent to 318 Earths. Following Jupiter, Saturn, Neptune, and Uranus formed, although the latter two were influenced by the gas already captured by the first two giants. In the inner Solar System, rocky planets, including Mars, took longer to develop due to collisions among protoplanets. Earth and Uranus are contenders for the title of the youngest planet, both having undergone significant collisions that shaped their current forms. Earth's collision with the Mars-sized Theia formed the Moon, while Uranus's impact altered its rotation and magnetic field, complicating the definition of planetary youth. 
Published: Apr 29 2025, 1 pmeznews.inAn analysis of a 108-million-year-old humerus bone from the species *Kryoryctes cadburyi* suggests that its owner was likely an aquatic or semi-aquatic animal, potentially indicating that the common ancestor of all monotremes, which include the platypus and echidnas, lived a lifestyle more akin to that of the platypus. This finding, derived from non-destructive CT scans, reveals that the bone's thick walls and heavy structure resemble those of modern platypuses and other semi-aquatic mammals, hinting at an evolutionary shift where echidnas adapted to a terrestrial lifestyle. The study, led by Professor Suzanne Hand from the University of New South Wales, highlights the rarity of monotreme fossils and the challenges in understanding their evolutionary history. The research underscores the significance of *Kryoryctes cadburyi*, named after the chocolate company, in shedding light on the ancient lineage of these unique mammals.
Published: Apr 29 2025, 2 pmeznews.inResearch indicates that birthing positions such as squatting or kneeling can significantly benefit labor by widening the pelvic outlet, thereby shortening delivery times. Despite this, the majority of women in the United States still give birth on their backs, a practice that has been linked to prolonged labor and slower contractions. This position became prevalent in Western culture over the last 200 years, with its origins traced back to 17th-century France. While King Louis XIV is often cited as a catalyst for this change due to his alleged voyeuristic tendencies, it was actually the physician François Mariceau who popularized the reclining position for its comfort and accessibility for midwives. Although the king's influence on birthing practices remains debated, his promotion of this position has left a lasting legacy, which continues to dominate in Western childbirth today.
Published: Apr 25 2025, 5 ameznews.inIn a remarkable incident in Peru, Rosa Isabel Céspedes Callaca, 36, was initially declared dead following a severe car accident on April 25. After her family began funeral preparations, she reportedly showed signs of life during the service on April 26, prompting cemetery staff to call for medical assistance. Transferred back to the hospital, Callaca was found to have a faint pulse, leading her family to suspect she had been in a deep coma rather than truly deceased. The regional health director confirmed an investigation into the hospital's handling of the case is underway. Experts note that biological processes can continue after apparent death, complicating definitions of mortality. Tragically, despite being placed on a respirator, Callaca was pronounced dead again within hours, leaving her family seeking answers about the circumstances surrounding her initial declaration of death.
Published: Apr 29 2025, 9 ameznews.inA recent study has shed light on the remarkable adaptations of deep-sea fish, which thrive in extreme conditions characterized by near-zero temperatures, low oxygen levels, and immense pressure. Researchers analyzed the genetics of 11 species, including the Philippine hadal snailfish and Bombay duck, found at depths ranging from 1,218 to 7,730 meters. The study revealed that these fish exhibit lower mutation rates but heightened natural selection, particularly in genes related to DNA repair and vision. Notably, a mutation in the _rtf1_ gene, common among fish living below 3,000 meters, exemplifies rapid convergent evolution, enabling these species to cope with crushing pressure. The findings confirm that deep-sea fish evolved through two distinct pathways: ancient survivors and new immigrants. Alarmingly, the study also found high levels of toxic polychlorinated biphenyls (PCBs) in hadal snailfish, highlighting the pervasive impact of human pollution even in the ocean's depths.
Published: Apr 28 2025, 6 ameznews.inResearchers at the University of Arizona have unveiled the world's fastest electron microscope, capable of capturing images in a single attosecond, a time frame equivalent to one billionth of a billionth of a second. This groundbreaking technology allows scientists to observe electron motion in real-time, a feat previously unattainable with earlier electron microscopes that operated on longer time scales. Senior author Mohammed Hassan likened the innovation to a high-resolution camera upgrade, enabling unprecedented insights into quantum physics and electron behavior. The development builds on decades of attosecond physics research, which was recognized with a Nobel Prize last year. The new technique, termed "attomicroscopy," synchronizes ultrashort light pulses with electron beams, marking a significant leap in temporal resolution. This advancement opens avenues for potential control over chemical and biological processes, as researchers continue to explore the fundamental dynamics of electrons. The findings are detailed in the journal Science Advances.
Published: Apr 29 2025, 7 ameznews.inThe case of Melissa Caddick has underscored the intricate challenges of marine forensics, particularly in understanding how human remains can end up in water. A foot found in a shoe suggested her body may have initially sunk before surfacing. Factors influencing whether bodies sink or float include the cause of death, water type, and decomposition processes. Human bodies, being largely composed of water, typically sink unless buoyancy is introduced through gases produced during decomposition. Studies indicate drowning victims can sink within seconds, while bodies may float after several days due to gas accumulation. Environmental conditions, such as temperature and salinity, significantly affect decomposition rates, with colder waters slowing the process. This knowledge aids forensic investigations, helping to determine the timeline of a body’s presence in water and enhancing search efforts for missing persons.
Published: Apr 25 2025, 12 ameznews.inA recent exploration into the world of parasitic nematodes, specifically the Mermithidae family, reveals a chilling relationship with spiders that could rival a scene from the film *Alien*. These worms, which typically target insects, can also infect spiders, entering their hosts either through direct penetration or via prey. A 2024 study identified mermithid infections in several spider species, noting that these parasites can cause abnormal genital development and alter growth patterns. Remarkably, infected spiders exhibit behavior changes, often seeking water—essential for the worms' emergence into their adult stage. An anecdote from writer Mike Gray highlights a bizarre incident where a huntsman spider, possibly infected, fell into a cup of coffee, leading to the worm's exit. This unsettling dynamic underscores the complex and often gruesome interactions within ecosystems, prompting a reconsideration of our perceptions of spiders.
Published: Apr 26 2025, 6 ameznews.inA potential shift in audio-visual connectivity is emerging as reports from China suggest that HDMI (High-Definition Multimedia Interface), a standard since 2002, may soon be replaced by GPMI (General Purpose Media Interface). While HDMI has been pivotal in linking devices with its ability to transmit both audio and video, GPMI promises to double the data transfer rate to 192 Gbps and deliver up to 480 watts of power, making it a more versatile option. Backed by major Chinese companies like Huawei and Hisense, GPMI has received approval from the USB Association, ensuring compatibility with existing hardware. However, its adoption outside China remains uncertain, with industry giants like LG and Samsung yet to commit. Despite its advantages, experts caution that current HDMI and USB-C standards are still adequate, suggesting consumers need not rush to replace their devices just yet. The rollout of GPMI-compatible products may take time, with significant changes likely years away.
Published: Apr 29 2025, 3 ameznews.inIn a groundbreaking experiment, physicists have successfully created a "black hole bomb" in the laboratory, providing experimental evidence for the long-theorized Zel’dovich effect, first proposed by British physicist Roger Penrose in 1969. The Penrose process suggests that energy can be extracted from black holes by manipulating objects within their ergosphere, where negative energy can be harnessed. Building on this concept, researchers led by Dr. Marion Cromb demonstrated that a rotating aluminum cylinder could amplify electromagnetic waves, mimicking the energy extraction process of a black hole. By creating conditions that allowed the cylinder to reflect and amplify energy from a surrounding electromagnetic field, the team observed exponential amplification, akin to a black hole bomb. While this experiment does not directly extract energy from black holes, it opens avenues for future research into spontaneous electromagnetic wave generation and amplification, marking a significant step in theoretical physics. The findings are currently available on the preprint server arXiv.
