Researchers have provided a new estimate for the universe's expansion rate, known as the Hubble constant, which highlights the ongoing Hubble tension—a significant discrepancy in measurements. Different methods yield varying results: the European Space Agency's Planck satellite estimates the rate at 67.4 kilometers per second per megaparsec, while other observations suggest a higher value of 72.8 kilometers per second per megaparsec. The latest findings from time-delay cosmography, which utilizes gravitational lensing, indicate a value of 71.6 kilometers per second per megaparsec, aligning more closely with the galaxy method but still diverging from the cosmic microwave background measurements. This discrepancy raises critical questions about our understanding of the universe, with experts like Professor Tommaso Treu emphasizing the need for further independent measurements to determine whether this is a new phenomenon or a result of measurement errors. The study is published in Astronomy and Astrophysics. 
Published: Dec 08 2025, 11 pmeznews.inA recent study analyzing over 28 million days of data from more than 70,000 participants has revealed the intricate relationship between sleep and physical activity. While only 13% of individuals met both recommended sleep and exercise targets, the findings suggest that quality sleep significantly enhances the likelihood of increased physical activity the following day. Specifically, those who achieved over seven hours of restful sleep tended to be more active, whereas achieving daily step goals did not correlate with improved sleep quality. Researchers emphasize that prioritizing sleep may be the most effective strategy for boosting energy and motivation for exercise. Simple lifestyle adjustments, such as reducing screen time before bed and maintaining a consistent sleep schedule, can greatly enhance sleep quality, ultimately supporting a healthier, more active lifestyle. The study highlights the challenges of balancing sleep and exercise in real life, calling for a reevaluation of health guidelines to better accommodate individual circumstances.

The study, led by Keith Crandall, involved 129 students who collected skin samples from various body parts, including commonly overlooked areas like the navel and behind the ears. Findings indicated that regions regularly cleaned, such as forearms and calves, exhibited a more diverse and healthier microbiome compared to neglected areas. The research highlighted that dry skin regions were richer and functionally distinct, while moist areas showed less diversity. Crandall noted that an imbalance in the skin microbiome could lead to conditions like eczema and acne, emphasizing the need for further investigation into the relationship between microbiome health and overall human health. This study serves as a foundational reference for understanding healthy adult microbiomes.
Published: Dec 06 2025, 5 pmeznews.inRecent discussions in the scientific community have highlighted the fascinating phenomenon of tails in celestial bodies, particularly in the context of comet 3I/ATLAS, which has developed both a tail and a rare anti-tail during its journey through the Solar System. However, comets are not alone in this characteristic; Mercury also possesses a sodium tail, created by its thin atmosphere interacting with solar radiation. Interestingly, Earth has its own tail, known as the "magnetotail," which extends at least 2 million kilometers into space. This tail is formed by the Earth's magnetosphere, which traps plasma and is shaped by the solar wind. The magnetotail can fluctuate in size and shape, influenced by solar events such as coronal mass ejections. Despite extensive exploration by spacecraft, many mysteries about this vast region remain, as its sheer size complicates detailed study.
Published: Dec 09 2025, 8 pmeznews.inA groundbreaking gene therapy, BE-CAR7, has shown remarkable promise in treating previously incurable cancers, particularly aggressive forms of leukemia, with 64% of trial patients remaining cancer-free after three years. Developed by researchers at Great Ormond Street Hospital and University College London, the treatment involves modifying donor white blood cells to target and destroy cancerous T-cells. The trial, which included eight children and two adults, reported that 82% achieved significant remission, allowing them to proceed to bone marrow transplants. Among the first patients, 16-year-old Alyssa Tapley, who had exhausted standard treatment options, has remained cancer-free since her participation. While the treatment offers hope, it is not without risks, as some patients faced severe side effects. The study's findings, presented at the American Society of Hematology Annual Meeting, highlight the potential of immunotherapies in revolutionizing cancer treatment.
Published: Dec 09 2025, 9 pmeznews.inGalaxy NGC 3783, renowned for its striking spiral arms, conceals a dynamic supermassive black hole at its core, which is generating unprecedented winds at one-fifth the speed of light. This remarkable phenomenon was observed using the European Space Agency’s XMM-Newton and the X-Ray Imaging and Spectroscopy Mission (XRISM), revealing that a bright X-ray flare from the black hole triggers these ultra-fast winds within just one day. The black hole, located approximately 130 million light-years from Earth and weighing 30 million times that of the Sun, is classified as an Active Galactic Nucleus (AGN). Researchers highlight the significance of understanding these winds, as they play a crucial role in galaxy evolution and star formation. The study, published in Astronomy & Astrophysics, underscores the parallels between solar flares and black hole activity, offering insights into the complex processes governing both cosmic phenomena.
Published: Dec 09 2025, 6 pmeznews.inUK health authorities have detected a new strain of the mpox virus in an individual who recently returned from Asia. This strain, which has not yet been officially named, exhibits genetic elements from two existing strains, clade Ib and clade IIb. Mpox, formerly known as monkeypox, presents with initial symptoms such as fever and muscle aches, followed by a blister-like rash that can be painful and may take weeks to heal. While the infection is generally mild for many, it poses greater risks to vulnerable populations, including young children and pregnant individuals. An effective vaccine is available in the UK, targeting high-risk groups. The emergence of this new strain, while not alarming, is being monitored closely by health officials, as viruses naturally evolve. Dr. Katy Sinka from the UK Health Security Agency emphasized the importance of vaccination to prevent severe disease.
Published: Dec 09 2025, 7 pmeznews.inThe colorful balls seen on overhead power lines across the United States serve a crucial safety function rather than being weights or weather sensors, as some have speculated. These visibility markers, required by the Federal Aviation Administration (FAA), are designed to alert pilots to the presence of power lines, particularly in areas with higher risks of collision, such as near busy airports, mountain passes, and open fields. Typically larger than 91 centimeters in diameter, these balls are often painted in "aviation orange," white, or yellow to enhance visibility against various backgrounds. Despite these precautions, incidents of aircraft colliding with power lines do occur, although they are rare. The FAA recommends that these markers be spaced approximately 61 meters apart along the highest wire to maximize their effectiveness in preventing accidents.
