eznews.inIn March 1986, the Soyuz T-15 mission made history as the only spaceflight to visit two space stations in a single trip, amid the backdrop of the Cold War. Launched to address the impending decommissioning of the aging Salyut-7 space station, cosmonauts Leonid Kizim and Vladimir Solovyov first activated the newly launched Mir station before returning to Salyut-7 to complete unfinished military and scientific experiments. Despite technical challenges, including a malfunctioning mainframe, the duo successfully conducted spacewalks and salvaged equipment, ultimately transporting 400 kilograms of cargo back to Mir. Their mission, initially set for six months, concluded early after four months due to the completion of objectives. While Mir thrived for 15 years, Salyut-7 met a less dignified end, crashing in Argentina in 1991. The Soyuz T-15 mission remains a unique achievement in space exploration history. 
Published: Jul 05 2025, 9 pmeznews.inA bison tragically succumbed to the dangers of Yellowstone National Park's thermal features on June 21, 2025, after it fell into the scalding waters of the Grand Prismatic Spring, which reaches temperatures of 89°C (192°F). Witnesses observed the animal stumble into shallow water before disappearing into deeper, perilous depths. The park authorities have opted not to recover the bison, which will soon become bones, highlighting the inherent risks of the park's vibrant wilderness. This incident serves as a stark reminder of the dangers posed by thermal areas, where crusts can give way, leading animals to plunge into boiling water. Contrary to popular belief, the primary threat is not acidity but extreme temperature, which can be fatal to both wildlife and humans. The Yellowstone Volcano Observatory emphasizes the importance of adhering to safety guidelines, urging visitors to remain on designated boardwalks to avoid similar fates.
Published: Jul 05 2025, 1 ameznews.inThe US Department of Defense has identified climate change as a significant global security threat, yet paradoxically, its military is the largest institutional producer of greenhouse gas emissions worldwide. Between 2010 and 2019, the US armed forces emitted 636 million metric tons of CO2, despite a decline in annual emissions from 76 million to 55 million metric tons. This substantial carbon footprint stems from the military's extensive global operations, which include 900 domestic and nearly 800 international bases. A recent study indicates that reductions in military spending correlate with decreased energy consumption, particularly in jet fuel. As global military expenditure surged by 9.4% in 2024, including a 5.7% increase in the US defense budget to $997 billion, emissions are expected to rise, exacerbating climate change and potentially leading to greater instability. The study emphasizes the need for sustainability within military operations to align with global security objectives.
Published: Jul 05 2025, 10 pmeznews.inA groundbreaking study has resolved a long-standing debate in neuroscience, confirming that human brains continue to generate new neurons throughout life, particularly in the hippocampus, which is vital for learning and memory. Previously, it was believed that neurogenesis ceased after childhood, despite evidence from studies on adult mice. The turning point came in 2013 when research indicated the presence of young neurons in adult cancer patients. To clarify the issue, researchers led by Jonas Frisén at Karolinska Institutet utilized RNA sequencing and machine learning to identify neuronal progenitor cells in brain tissue from individuals aged zero to 78. Their findings revealed that while neurogenesis rates are higher in children, these progenitor cells persist in adults, albeit with significant variation. This research not only enhances our understanding of brain function but may also inform regenerative treatments for neurodegenerative and psychiatric disorders. The study is published in the journal Science.
Published: Jul 05 2025, 5 pmeznews.inA team of researchers has proposed a new "direct fusion drive" propulsion system that could enable a mission to the dwarf planet Sedna within this century, marking a rare opportunity to study a potential Oort cloud object. Discovered in 2003, Sedna orbits the Sun at an average distance of 13 billion kilometers (8 billion miles) and is on an 11,000-year journey that will bring it closest to the Sun in July 2076, at approximately 76.37 AU. Traditional propulsion methods are deemed inefficient for such long-distance missions, prompting the exploration of innovative systems like the thermonuclear Direct Fusion Drive (DFD) and solar sails. The DFD could reduce travel time to Sedna by 50%, reaching it in about 10 years, while a solar sail could make the journey in 7 years, albeit with a smaller payload. As mission proposals are being developed, researchers emphasize the urgency of launching before Sedna moves away for millennia.
Published: Jun 30 2025, 9 pmeznews.inIn the high altitudes of the Tibetan Plateau, the dzo, a hybrid of yak and cow, has thrived for over 2,300 years, serving as a vital pack animal. Males, known as dzo, are infertile, while females, or dzomo, can reproduce and even backcross with their parent species, creating a complex gene pool. Recent genetic research revealed that yaks were first domesticated in the region 7,500 years ago, with hybridization occurring between 2,670 and 2,360 years ago. The dzo combines the hardiness of yaks, adapted to harsh mountain conditions, with the milk production capabilities of domestic cattle. This hybridization is increasingly relevant as climate change poses challenges for pastoral communities like the Brokpa in the eastern Himalayas, who are crossbreeding yaks with hybrids to develop breeds better suited to warmer temperatures and changing environments.
Published: Jul 05 2025, 12 pmeznews.inKimalu, a beluga whale at Chicago's Shedd Aquarium, has made history by becoming the first known beluga to survive general anesthesia following a pioneering surgery to remove cysts from her head. Weighing over 453 kilograms (1,000 pounds), Kimalu's condition was detected during routine check-ups, prompting a CT scan that revealed the need for surgery. The complex procedure involved around 30 experts, including human surgeons and veterinary specialists, who relied on their deep understanding of Kimalu's unique physiology. Dr. Karisa Tang, vice president of animal health at Shedd, expressed the emotional weight of the operation, stating, "There were moments when it felt like we were all holding our breath simultaneously." Post-surgery, Kimalu was placed in a recovery habitat, surrounded by familiar sounds from her pod, as she begins her healing journey, which remains closely monitored by her dedicated team.
Published: Jul 05 2025, 7 ameznews.inA recent analysis of data from the National Electronic Injury Surveillance System (NEISS) reveals a troubling trend in the U.S. regarding sex toy-related injuries, with a notable increase in emergency room visits over the past decade. The study, which focused on incidents involving vibrators, butt plugs, and other devices, found that the majority of mishaps occurred in the rectum (69.5%), followed by the vagina (16.5%) and penis (12.1%). Vibrators topped the list of "stuck" toys, often due to their lack of a flared base. Experts attribute the rise in incidents to the growing normalization of sex toys, increased accessibility, and a lack of education on safe usage practices. Dr. Carol Queen emphasizes the need for comprehensive sex education that includes safe anal play and toy safety to prevent such accidents. As societal attitudes shift, the importance of informed and safe sexual exploration becomes paramount to avoid becoming a statistic.
Published: Jul 04 2025, 10 ameznews.inThe White House has dismissed speculation about extraterrestrial involvement in the recent downing of four unidentified flying objects over North America, with Press Secretary Karine Jean-Pierre stating there is "no indication of aliens." The latest object, described as an "octagonal structure" with strings, was shot down by F-16 fighter jets over Lake Huron on February 12, after being detected over Montana. This incident follows the downing of a Chinese high-altitude balloon on February 4, which China claimed was for meteorological purposes, while the US alleged it was for espionage. The military has initiated a task force to recover and analyze the debris from the latest object, which poses a potential hazard to civil aviation. Meanwhile, tensions between the US and China have escalated, with China accusing the US of violating its airspace with balloons, leading to the postponement of a planned state visit by US Secretary of State Antony Blinken.
Published: Jul 01 2025, 6 ameznews.inSpacecraft differ significantly from cinematic starships, as they operate under the constraints of limited fuel and orbital mechanics. Currently, only five probes—Voyager 1 and 2, Pioneer 10 and 11, and New Horizons—are on trajectories to interstellar space, with Voyager 1 and 2 already having exited the Solar System. Achieving escape velocity is crucial for any rocket launch, requiring a speed of at least 11.2 kilometers per second to overcome Earth's gravitational pull. Efficient launch strategies, such as launching near the equator, help maximize velocity. Once in space, a spacecraft must reach over 42 kilometers per second to escape the Sun's gravity. While the gravitational influence of the Sun slows these probes, they maintain sufficient speed to continue their journey. With two probes beyond the heliosphere and three others en route, humanity has successfully ventured beyond the Solar System, marking a significant achievement in space exploration.
