Researchers propose a novel approach to uncover the elusive nature of dark matter by searching for "dark dwarfs," faint celestial objects potentially illuminated by dark matter interactions. The study, led by Dr. Jeremy Sakstein from the University of Hawai’i, suggests that if dark matter, likely composed of Weakly Interacting Massive Particles (WIMPs), accumulates within stars, it could lead to energy release and increased brightness. Unlike typical brown dwarfs, which lack sufficient mass for hydrogen fusion, these "dark dwarfs" could exhibit unique characteristics, such as elevated levels of lithium-7, a marker that could help distinguish them from ordinary stars. While locating these objects poses challenges due to their distance and the crowded galactic center, the James Webb Space Telescope (JWST) may aid in detecting lithium-7, potentially confirming the presence of WIMPs and advancing our understanding of dark matter. The findings are detailed in the Journal of Cosmology and Astroparticle Physics.

First proposed by mathematician John Conway in the 1960s, the challenge was to create a four-sided shape that defied previous assumptions about balance. Gábor Domokos, a professor at Budapest University, and his student Gergő Almádi embarked on a quest to find this elusive shape, utilizing modern computational methods. After extensive trials, they constructed the Bille using ultra-light carbon fiber and tungsten carbide, achieving a functional design after overcoming initial setbacks. The Bille not only serves as a mathematical curiosity but also holds potential applications in space exploration, offering solutions for self-righting mechanisms in spacecraft. This innovative shape could pave the way for future advancements in both mathematics and engineering, highlighting the intersection of theoretical concepts and practical applications.
Published: Jul 04 2025, 10 pmeznews.inNASA's Galileo probe, launched in 1989, marked a significant milestone in our exploration of Jupiter, becoming the first spacecraft to orbit the gas giant. After gaining a gravity assist from Venus, Galileo arrived at Jupiter in 1995, embarking on a 23-month mission that included 35 encounters with its major moons. The probe provided groundbreaking insights, revealing intense volcanic activity on Io, a subsurface ocean on Europa, and the magnetic field around Ganymede. Notably, Galileo also witnessed the impact of Comet Shoemaker-Levy 9 on Jupiter. In a dramatic highlight, a descent probe was released into Jupiter's atmosphere, transmitting valuable data on atmospheric composition before succumbing to extreme conditions. Ultimately, in 2003, NASA intentionally crashed Galileo into Jupiter to prevent any potential contamination of Europa, which may harbor conditions suitable for life, ensuring the integrity of future explorations.
Published: Jul 08 2025, 9 pmeznews.inAstronomers have traced the origin of newly discovered interstellar Comet 3I/ATLAS, revealing it likely comes from an ancient star in the thick disc of the Milky Way, potentially predating the Solar System itself. Discovered just a week ago, the comet exhibits significant differences from previous interstellar visitors, moving nearly twice as fast as its predecessors at approximately 57 kilometers per second. Researchers, including lead author Matthew Hopkins, utilized a new model to analyze the comet's trajectory and characteristics, suggesting it has been traveling through space for over 7 billion years. The comet's reddish hue indicates it has been altered by cosmic rays, and scientists anticipate that as it approaches the Sun, it may exhibit increased cometary activity. This discovery adds to the understanding of the vast population of interstellar objects, with estimates suggesting billions exist within our galaxy. The findings are set to be published in The Astrophysical Journal Letters.
Published: Jul 08 2025, 10 pmeznews.inNASA's Cassini spacecraft, launched in 1997, revolutionized our understanding of Saturn and its moons after arriving at the gas giant on July 1, 2004. Following initial flybys by Pioneer 11 and Voyager missions, Cassini embarked on a seven-year mission that included detailed observations of Saturn's dynamic moons, particularly Titan, which scientists believe shares similarities with early Earth. The mission was extended multiple times, culminating in the "Grand Finale," where Cassini performed 22 daring dives between Saturn's rings and its atmosphere. This phase provided unprecedented data on Saturn's magnetic fields and ring composition. On September 15, 2017, after 293 orbits, Cassini was deliberately plunged into Saturn to protect its moons, particularly Enceladus and Titan, from contamination. The spacecraft sent back its final images and data before disintegrating in the planet's atmosphere, marking the end of a groundbreaking exploration mission.
Published: Jul 08 2025, 7 pmeznews.inA Kansas family lived with an astonishing 2,055 brown recluse spiders in their home over five and a half years, according to a recent case report. The family, which included two children, discovered the spiders—known for their venomous bites—after moving into the 19th-century house in 1996. Researchers collected and documented the spiders during a six-month study in 2001, finding that 488 of them were capable of envenomation. Despite the high number of potentially dangerous spiders, the family reported no bites, suggesting that medical professionals may be misdiagnosing skin lesions as spider bites in areas where brown recluse populations are not established. The study highlights the spiders' role in pest control and challenges the perception of their danger, noting that severe reactions to bites are rare and often linked to bacterial infections rather than venom. The findings were published in the *Journal of Medical Entomology*.
Published: Jul 08 2025, 5 pmeznews.inScientists exploring the South China Sea were surprised to encounter eight Pacific sleeper sharks (_Somniosus pacificus_) while investigating the ecological processes surrounding whale carcasses. The sharks, which typically inhabit colder waters, were observed feeding on a cow carcass dropped at a depth of 1,629 meters (5,344 feet) near Hainan Island. Video footage revealed not only their predation behavior but also a surprising queuing system, where sharks in front allowed those behind to feed, suggesting a complex social structure. Larger sharks, measuring over 2.7 meters (8.9 feet), displayed more aggressive feeding behaviors, while smaller ones were more cautious. The presence of parasites and other deep-sea organisms, such as snailfish and amphipods, was also noted. This unexpected sighting raises questions about the sharks' distribution and whether their presence in this region indicates a range expansion potentially linked to climate change, as their typical habitat spans from Japan to Alaska.
Published: Jul 08 2025, 8 pmeznews.inIn a surprising turn of events, the Earth is set to speed up its rotation, with July 9 marking the first of three notably short days this summer, each expected to be shorter than the standard 86,400 seconds. Tomorrow's day will be approximately 1.30 milliseconds shorter, a phenomenon that has puzzled scientists, including Leonid Zotov, an expert on Earth rotation, who noted that current ocean and atmospheric models fail to explain this acceleration. Historically, the Earth has been slowing down, primarily due to the Moon's gradual distancing, which has led to the addition of 27 leap seconds since 1972. However, since 2020, the trend has reversed, with 28 of the shortest days recorded since 1960. Factors such as earthquakes can influence rotation speed, but the recent acceleration remains unexplained, prompting ongoing monitoring by the International Earth Rotation and Reference Systems Service.
Published: Jul 08 2025, 6 pmeznews.inDespite the unappealing appearance of packaged meats, washing chicken before cooking is not advisable, according to the Centers for Disease Control and Prevention (CDC). Raw chicken can harbor harmful bacteria like _Campylobacter_ and _Salmonella_, which are common causes of food poisoning. Washing the meat can inadvertently spread these bacteria around the kitchen, increasing the risk of contamination. A study from North Carolina State University found that 35% of participants washed their chicken, often to remove visible residue, but both washers and non-washers contaminated kitchen surfaces. The key to food safety lies in proper cooking and hand hygiene rather than washing the chicken. To stay healthy, experts recommend skipping the rinse and cooking the chicken directly, as the cooking process effectively eliminates harmful bacteria.
Published: Jul 05 2025, 2 pmeznews.inResearchers from the US and Germany have discovered that individuals with high psychopathy exhibit structural changes in brain regions associated with impulse control and emotional regulation. Using advanced neuroimaging techniques, the study examined 39 male subjects identified through the Psychopathy Checklist-Revised, revealing that those with elevated scores had 1.45% less total brain volume compared to control subjects, particularly in areas like the basal ganglia and insular cortex, which are crucial for emotional processing and moral judgment. While the findings suggest a link between psychopathy traits and brain structure, the study's small sample size and potential confounding factors, such as prior drug use, warrant caution in interpretation. The results underscore the need for further research to explore the heritability and environmental influences on these structural differences, potentially paving the way for new treatment and rehabilitation strategies for individuals exhibiting psychopathic traits. The study was published in the *European Archives of Psychiatry and Clinical Neuroscience*.
