Last week, the COSMOS collaboration unveiled COSMOS-Web, a groundbreaking catalog of galaxies that significantly surpasses the Hubble Ultra Deep Field, featuring 800,000 galaxies and extending back 13.5 billion years, or 98% of the universe's age. This expansive dataset, described by UC Santa Barbara's Caitlin Casey as a mural larger than 13 feet square, challenges previous assumptions about galaxy formation, revealing ten times more galaxies than expected at such distances and uncovering supermassive black holes invisible to Hubble. While the data offers insights into the early universe and cosmic matter distribution, it also raises questions about established cosmological models, particularly regarding the rapid formation of stars and galaxies. The COSMOS-Web data is publicly accessible, promoting a collaborative approach to scientific discovery, as researchers worldwide are encouraged to explore its mysteries. Papers detailing the findings have been submitted to leading astrophysical journals. 
Published: Jun 12 2025, 9 pmeznews.inA mystery unfolded at the Aquarium and Shark Lab in Hendersonville, North Carolina, earlier this year when a stingray named Charlotte appeared to be pregnant despite the absence of male stingrays. Speculation arose that she could have been impregnated by a male shark, as two young bamboo sharks had recently been introduced to her tank. However, after extensive testing, the aquarium announced a more troubling development: Charlotte was diagnosed with a rare reproductive disease that has adversely affected her reproductive system. The aquarium's team, Team ECCO, expressed their commitment to Charlotte's health and well-being, stating they would collaborate with veterinarians to explore treatment options. While the possibility of parthenogenesis—where an embryo develops without fertilization—was considered, the aquarium did not confirm whether Charlotte was ever pregnant. They hope that insights gained from her case will contribute to scientific understanding and benefit other rays in the future.
Published: Jun 15 2025, 11 ameznews.inGorillas, despite their impressive size and strength, possess the smallest penises relative to body size among mammals, measuring just 3 centimeters (1.1 inches). This surprising fact is linked to their social structure, where a dominant male typically mates with multiple females, reducing the need for larger genitalia. Unlike their chimpanzee relatives, who live in multi-male groups and require larger testes to compete for female attention, gorillas rely on physical dominance rather than sperm competition. Research indicates that gorilla sperm is not only low in quantity but also less effective, with poor motility and function. Interestingly, genetic similarities between gorillas and humans suggest that these traits may influence human sperm counts as well. In contrast, humans have larger penises but smaller testes, reflecting a complex mating system influenced by social and resource factors, where intelligence and social status often dictate access to partners rather than physical attributes.
Published: Jun 15 2025, 3 pmeznews.inA recent study published in BJU International has revealed a significant increase in the depiction of human penis size in art over the past seven centuries, particularly since the 20th century. Researchers analyzed 232 paintings of nude males from 21 countries, focusing on the penis-to-ear and penis-to-nose ratios to assess changes in perceived ideal size. Findings indicated that while penis sizes were relatively small in the 15th and 16th centuries, they began to grow larger from the 19th century onward, culminating in an average ratio of 1.5761 in the 21st century. The study suggests that the rise in perceived size may be influenced by the internet and pornography, which often associate larger sizes with masculinity and partner satisfaction. The researchers caution that these evolving artistic representations could exacerbate body image issues among men, as many tend to overestimate average sizes and seek potentially harmful enhancements.
Published: Jun 15 2025, 6 ameznews.inA new video from National Geographic provides an in-depth look at the fascinating journey food takes through the human digestive system. Beginning in the mouth, the video follows the path of food as it travels to the stomach, through the intestines, and ultimately to the rectum for excretion. While the process is a natural part of human biology, it can be perceived as somewhat unappealing when observed closely. The video aims to educate viewers on the complexities of digestion, shedding light on how our bodies process what we eat. With a touch of humor, the article playfully acknowledges the sometimes uncomfortable nature of discussing digestion, stating, "I would make a joke about the natural, but still kind of gross to observe first hand, process making your stomach turn, but I don't have the guts."
Published: Jun 15 2025, 4 ameznews.inA recent study from the NYU Grossman School of Medicine has revealed that children can experience long COVID, but symptoms vary significantly by age. Analyzing over 1,000 children, researchers found that 41% of toddlers under two and 45% of preschoolers aged three to five exhibited prolonged symptoms following COVID-19. Younger children often faced issues like sleep disturbances and increased fussiness, while older preschoolers reported dry cough and daytime fatigue. The study highlights the need for tailored screening approaches for long COVID across different age groups, as nearly 6 million US children could be affected. Despite limitations in confirming prior infections, the findings underscore the importance of recognizing long COVID in children, especially as discussions around COVID vaccination for kids evolve. Current CDC guidelines recommend vaccinations for all children aged six months and older, amid concerns about potential changes in vaccination policies that could leave children vulnerable.
Published: Jun 15 2025, 2 ameznews.inThe Simulation Hypothesis, which posits that our reality may be a computer-generated simulation, continues to intrigue many despite significant skepticism. Prominent figures like Elon Musk and astrophysicist Neil deGrasse Tyson have expressed support for the idea, with Tyson suggesting the odds of living in a simulation are "better than 50-50." However, critics argue that the hypothesis lacks scientific validity, as it cannot be confirmed or disproven, rendering it more a philosophical speculation than a scientific theory. Rooted in historical skeptical hypotheses, such as René Descartes' Evil Demon concept, the Simulation Hypothesis has evolved into a metaphysical assertion about reality. Philosopher Nick Boström's statistical reasoning suggests that if advanced civilizations can create simulations, it is likely we are among the simulated. Yet, experts like Sabine Hossenfelder caution that the hypothesis is vague and lacks a coherent framework, likening its appeal to religious beliefs about predestination and divine control over human experiences.
Published: Jun 14 2025, 7 pmeznews.inGenghis Khan, born Temüjin, is a polarizing historical figure known for uniting Mongolia and establishing an empire that stretched from China to the Adriatic Sea. A 2003 genetic study revealed that nearly one in 12 men in Asia share a unique Y-chromosomal lineage likely linked to Khan, suggesting that about 16 million men worldwide may be his descendants. This lineage's prevalence is attributed to cultural factors rather than mere biological selection, as Khan's conquests decimated local populations, allowing his genetic line to flourish. Officially, he had at least nine children with his primary wife, Börte, but the true number may be higher due to numerous concubines. Despite his genetic legacy, Khan is also remembered for the brutality of his campaigns, which resulted in the deaths of millions. While other historical figures have left significant genetic footprints, none match the scale of Genghis Khan's legacy.
Published: Jun 13 2025, 10 pmeznews.inJune marks the solstice in the Northern Hemisphere, bringing the shortest night of the year, but it also heralds "core season" for the Milky Way. This month, stargazers are encouraged to venture into dark, secluded areas away from city lights to witness the galaxy's core, which appears as a hazy band of light arching across the night sky. NASA's Jet Propulsion Laboratory explains that this view is from within the Milky Way, allowing us to see its structure edge-on. While it may seem paradoxical to observe the galaxy from inside it, the perspective reveals a bright central core, with the left and right edges representing material in the opposite direction. For those seeking guidance, the Summer Triangle—comprising the stars Deneb, Vega, and Altair—can help locate the Milky Way. Observing this celestial spectacle offers a profound connection to the cosmos, especially through long-exposure photography.
Published: Jun 13 2025, 9 pmeznews.inIn a groundbreaking discovery, a clouded leopard (_Neofelis nebulosa_) has been captured on camera preying on a Bengal slow loris (_Nycticebus bengalensis_) for the first time, shedding light on the predatory behavior of this elusive species. The incident occurred on December 7, 2024, in Dehing Patkai National Park, Assam, India, where a camera trap recorded the leopard carrying the slow loris in its mouth. This finding is significant for conservation efforts, as both species are listed as Vulnerable and Endangered, respectively, by the IUCN. Clouded leopards are adept climbers and nocturnal hunters, while slow lorises are known for their slow movements and tree-dwelling habits. The camera trap is part of a larger study involving 95 cameras aimed at understanding the behaviors of various wild cat species, ultimately aiding in the development of effective conservation strategies to combat threats like habitat loss and illegal hunting. The study is published in the Journal of Wildlife Science.
