The concept of artificial gravity, rooted in Einstein's theory of relativity, suggests that it can be created in low-gravity environments through constant acceleration or by using a rotating spacecraft to generate centrifugal force. While this could benefit astronauts who experience adverse effects from prolonged weightlessness, such as muscle atrophy and bone loss, practical implementation poses challenges. Experts note that creating comfortable artificial gravity would require a spacecraft larger than a football field, as smaller designs would lead to significant gravitational differences between the head and feet. Moreover, the International Space Station (ISS) serves as a unique laboratory for conducting experiments in microgravity, making the introduction of artificial gravity counterproductive to its research objectives. NASA emphasizes that the ISS's purpose is to explore the effects of microgravity on various scientific disciplines, a goal that would be compromised by the presence of artificial gravity. 
Published: Jun 11 2025, 12 ameznews.inUnder the Trump administration, the relationship between science and governance has become increasingly contentious, with the emergence of "alternative facts" raising concerns about the integrity of scientific communication. Controversial oil pipelines have been revived even as the administration claims to support environmentalism, while references to climate change have been removed from the White House website. Federal agencies, including the EPA and USDA, have reportedly been instructed to halt public communications regarding their research, a move seen as an attempt to suppress information on climate change and environmental issues. Although some gag orders have been rescinded, the rapidity of these restrictions has alarmed many. In response, scientists are mobilizing through protests, open letters, and alternative social media accounts to resist this suppression and advocate for transparency in scientific discourse. As the battle for scientific integrity intensifies, the scientific community is rallying to ensure their voices are heard.
Published: Jun 12 2025, 5 pmeznews.inThe phrase "Crossing the Rubicon" signifies a decisive, irreversible action, rooted in the historical context of Julius Caesar's bold move in January 49 BCE. The Rubicon River, a modest stream in modern Italy, served as a boundary between Roman-controlled territories and Gaul. By crossing it, Caesar defied the Roman Senate, triggering a civil war that ultimately led to his rise to power and the decline of the Roman Republic. This act was not merely about crossing a physical barrier; it symbolized a critical choice amid a backdrop of political instability and social unrest. Caesar's famous declaration, "let a die be cast," encapsulated the gravity of his decision, which set in motion a series of events that reshaped Roman governance and paved the way for the emergence of the Roman Empire. The phrase endures today as a metaphor for taking bold, irrevocable steps in one's life.
Published: Jun 12 2025, 5 ameznews.inIn a rare and exciting development, a "ghost elephant" named Ousmane has been captured on camera for the first time in five years in Senegal's Niokolo-Koba National Park, where only five to ten of these elusive creatures are believed to remain. The footage, recorded by Panthera and Senegal’s National Parks Directorate, shows Ousmane, last seen in 2019, taking a nocturnal stroll. The park's teams are also analyzing dung samples for DNA to determine if other elephants exist, crucial for Ousmane's potential mating prospects. Once abundant, the elephant population has dwindled due to poaching and habitat loss, prompting discussions on enhanced protections and the possibility of establishing a breeding population. Conservation efforts face challenges, as relocating elephants has proven difficult, but success stories, such as the resurgence of West African lions, offer hope for the future of these rare elephants.
Published: Jun 11 2025, 4 pmeznews.inDiagrams and animations depicting planetary orbits often simplify complex gravitational dynamics, omitting the concept of barycenters to make the information more accessible for students. While the Sun is the dominant mass in the Solar System, it does not solely dictate the orbits of the planets. Instead, both the Sun and planets, including the massive gas giants Jupiter and Saturn, revolve around a common center of mass known as the barycenter, which is typically located just outside the Sun's surface due to Jupiter's significant mass. This means that Earth and other planets are not orbiting a fixed point within the Sun but rather this dynamic barycenter. Similarly, the Earth and Moon orbit a point outside the Earth's center, illustrating that celestial mechanics are more intricate than traditional educational models suggest. Understanding these complexities offers a deeper appreciation of our Solar System's structure.
Published: Jun 12 2025, 9 ameznews.inA recent study has revealed that some moonquakes detected by seismometers placed on the lunar surface during the Apollo 17 mission in the 1970s are linked to the lander itself. Researchers from Caltech utilized machine learning to analyze data from these seismographs, discovering that regular tremors occurred every afternoon as the lunar surface cooled. However, unusual signals were recorded in the mornings, attributed to the lander expanding and creaking as it heated up. This finding not only sheds light on the lander's behavior but also has implications for future lunar missions, particularly in mapping subsurface structures and searching for water ice in permanently shadowed regions near the Moon's South Pole. Meanwhile, India's Vikram lander, positioned nearby, has also detected potential underground movement, prompting further investigation. The study is published in JGR Planets.
Published: Jun 12 2025, 12 pmeznews.inAs people age, many report that time seems to accelerate, a phenomenon that has intrigued psychologists and neuroscientists alike. Theories suggest that this perception is linked to the amount of new information processed by the brain. Research by psychologist Robert Ornstein in the 1960s indicated that individuals perceive time differently based on the novelty of their experiences; more engaging stimuli make time feel longer. Dr. Christian Yates from the University of Bath notes that as adults become familiar with their surroundings, they pay less attention to detail, leading to a faster perception of time. Additionally, as our neural pathways age and become more complex, the processing of images slows down, contributing to the sensation that time is fleeting. Proportional theory also plays a role, as a year feels shorter relative to a longer life span. Ultimately, embracing new experiences may help counteract this swift passage of time.
Published: Jun 11 2025, 3 pmeznews.inFormer Apollo 14 astronaut Edgar Mitchell has made headlines with his claim that extraterrestrial beings intervened to prevent a nuclear war during the Cold War. In a recent interview, Mitchell suggested that aliens were particularly interested in the White Sands Missile Range in New Mexico, where the first atomic bomb was tested. He alleged that Air Force officers informed him of incidents where UFOs disabled or shot down missiles, implying that these beings aimed to maintain peace on Earth. While Mitchell's assertions have drawn skepticism, with UFO expert Nigel Watson dismissing them as "UFO fantasy," they highlight a notable shift from his historic achievements as the sixth man on the Moon. Despite his scientific background, Mitchell's increasingly bizarre theories have raised concerns about his detachment from reality, prompting calls for him to reconnect with more grounded perspectives.
Published: Jun 12 2025, 8 ameznews.inThe peculiar naming of the numbers eleven and twelve, distinct from the subsequent teens, can be traced back to historical counting systems, particularly the influence of base 12. While modern numeration predominantly uses base 10—likely due to the ten fingers on human hands—evidence suggests that ancient cultures may have employed a duodecimal system, which is more divisible and practical for grouping items. The terms "eleven" and "twelve" derive from Old English words meaning "one left over" and "two left over," respectively, reflecting this earlier counting method. Linguistic studies indicate that early Germanic languages also exhibited a base 12 influence, as seen in the Old Norse term "hundrað," which originally meant 120. This historical context highlights how remnants of base 12 persist in our language and numerical systems, despite the dominance of base 10 today.
Published: Jun 12 2025, 4 ameznews.inIn 1993, a nearly complete fossilized skeleton of a Neanderthal, dubbed "Altamura Man," was discovered in the Lamalunga cave in southern Italy, embedded in rock and covered with a mineral formation known as "cave popcorn." This unique feature, formed by calcite accumulation in wet cave areas, provided clues about the environment surrounding the skeleton. Researchers hypothesized that the man likely fell into a sinkhole, leading to starvation or dehydration before his remains were covered by the mineral deposits. Analysis of a shoulder blade fragment confirmed the skeleton's Neanderthal identity, dating back between 128,000 and 187,000 years. Further examination of his teeth indicated he was an adult who had lost a tooth weeks prior to his death, suggesting a challenging final period. Due to the delicate nature of the find, scientists opted to leave the skeleton undisturbed for ongoing study.
Published: Jun 10 2025, 11 pmeznews.inFour gray wolves from Canada have been airdropped into Michigan's Isle Royale National Park to address the burgeoning moose population, which has surged in the absence of these predators. This initiative, led by the Ontario Ministry of Natural Resources and Forestry (OMNRF), aims to revive the island's dwindling wolf population through a conservation strategy known as rewilding. The new arrivals, consisting of one female and three males, join two wolves introduced in September, with plans to release an additional 14 to 24 over the next few years. Historically, wolves could migrate to and from the mainland via an ice bridge, but climate change has disrupted this, leading to a drastic decline from 50 wolves in 1980 to just two in 2016. While the reintroduction is promising, experts caution about the stress on the wolves as they adapt to their new environment. Meanwhile, the U.S. government is reconsidering the gray wolf's status under the Endangered Species Act, sparking controversy among conservationists.
