  • Research establishes brain normative references for Chinese population

    Research establishes brain normative references for Chinese population

    A groundbreaking study conducted by Chinese researchers has successfully established comprehensive normative references for brain structure across the entire lifespan of the Chinese population, marking a significant advancement in neurological diagnostics. The research, led by Professor Liu Ya’ou from the Department of Radiology at Beijing Tiantan Hospital, addresses critical gaps in neurological healthcare specific to Chinese patients.

    The research initiative emerged from two fundamental challenges in China’s neurological diagnostics landscape. First, existing brain normative standards predominantly derive from Western populations, creating potential inaccuracies when applied to Chinese patients due to distinct genetic backgrounds and environmental factors. Second, the medical community lacked sufficient data to differentiate between normal aging processes and pathological neurological changes, often resulting in delayed diagnoses and missed intervention opportunities.

    To overcome these limitations, the collaborative team from Beijing Tiantan Hospital and Beijing Normal University analyzed an extensive dataset comprising magnetic resonance imaging scans from 24,061 healthy Chinese individuals and 3,932 patients with neurological disorders. Their comprehensive analysis established standardized reference ranges for 228 critical structural indicators specifically tailored to the Chinese population.

    Published in the prestigious international journal Nature Neuroscience, the findings demonstrate how individual brain deviation scores calculated from these normative references can rapidly quantify structural abnormalities and facilitate precise disease identification. The research reveals distinct neurological patterns: Alzheimer’s disease manifests through widespread deviations across multiple brain structures, Parkinson’s disease primarily affects deep gray matter, while multiple sclerosis predominantly involves white matter and thalamus volume alterations.

    This innovative framework, currently undergoing clinical pilot testing at Beijing Tiantan Hospital, enables earlier screening and diagnosis of neurological disorders while supporting more targeted treatment strategies. The research team is expanding collaborations with medical imaging corporations to integrate multi-modal imaging, blood biomarkers, and genetic testing data, further advancing precision medicine approaches for brain health and major neurological conditions.

  • First super moon of 2026 makes appearance in sky

    First super moon of 2026 makes appearance in sky

    The night sky unveiled a breathtaking astronomical phenomenon on January 3, 2026, as the first super moon of the year made its spectacular appearance. This celestial event, characterized by the moon’s unusually close orbital proximity to Earth, created a visually larger and significantly brighter lunar display than typical full moons.

    The remarkable phenomenon was captured in stunning photographs over Tongjiang city in Northeast China’s Heilongjiang province, where the super moon appeared as a magnificent luminous orb against the night canvas. This occurrence marks the initial of several super moons anticipated throughout 2026, each offering unique opportunities for astronomical observation and photography.

    Super moons occur when the moon’s elliptical orbit brings it to the closest point to Earth (perigee) simultaneously with the full moon phase. This orbital alignment can make the moon appear up to 14% larger and 30% brighter compared to its appearance at the farthest point (apogee). The scientific community emphasizes that while super moons create visually striking appearances, they remain a predictable orbital phenomenon rather than an unusual astronomical event.

    The January super moon attracted attention from both amateur stargazers and professional astronomers worldwide, serving as a reminder of the dynamic relationships within our celestial neighborhood. Such events continue to inspire public interest in astronomy and space science while providing researchers with opportunities to study the moon’s surface features under enhanced lighting conditions.

  • New Chinese study reveals Antarctic amplification mechanism

    New Chinese study reveals Antarctic amplification mechanism

    A groundbreaking study conducted by Chinese scientists has provided definitive confirmation of future Antarctic amplification while elucidating the precise physical mechanisms driving this critical climate phenomenon. Published recently in the prestigious journal Geophysical Research Letters, the research represents a significant advancement in understanding polar climate dynamics.

    Led by researchers from the Institute of Global Change and Polar Meteorology under the Chinese Academy of Meteorological Sciences (CAMS), the study resolves longstanding uncertainties regarding Antarctic warming patterns. While polar amplification has been well-documented in the Arctic, the Antarctic counterpart had remained subject to scientific debate until this comprehensive analysis.

    The research team employed an extensive dataset comprising observations from over 200 Antarctic monitoring stations, combined with China’s first-generation global atmospheric and land surface reanalysis products. This robust methodology enabled the first detection of a continent-wide warming signal across Antarctica’s vast expanse.

    Under the Paris Agreement’s 2 degrees Celsius warming scenario, the study demonstrates a pronounced warming signal over the Antarctic continent, with an overall warming magnitude approximately 1.4 times greater than the Southern Hemisphere average. Dr. Ding Minghu, head of the Institute of Global Change and Polar Research at CAMS, explained the mechanism: ‘The roaring westerlies of the Southern Hemisphere create an isolating effect, meaning human activities primarily influence Antarctica through sea surface warming and subsequent heat transfer. This explains why Antarctic warming has lagged behind other global regions.’

    The research further indicates that with continuously rising sea surface temperatures, Antarctic amplification will progressively intensify in coming decades, accompanied by an accelerated warming rate. This revelation highlights a substantial, previously underestimated human impact on the Antarctic climate system, with far-reaching implications for global sea level rise and climate modeling accuracy.

  • UK records hottest and sunniest year ever in 2025, says weather service

    UK records hottest and sunniest year ever in 2025, says weather service

    Britain’s national meteorological service has confirmed that 2025 stands as the most exceptionally warm and sun-drenched year in the nation’s recorded history, eclipsing previous benchmarks and underscoring an accelerating climate transformation. According to Friday’s announcement from the Met Office, the average annual temperature reached 10.09°C (50.16°F), marginally surpassing the 2022 record of 10.03°C. This milestone represents only the second occasion since comprehensive record-keeping commenced in 1884 that the yearly mean temperature has breached the 10°C threshold.

    The meteorological data reveals a particularly concerning pattern: four of the most recent five years now rank among the top five warmest periods in over 140 years of documentation. This clustering of record-breaking temperatures within such a compressed timeframe provides compelling evidence of rapidly shifting climatic conditions. The persistent dominance of high-pressure weather systems combined with unusually elevated sea temperatures have been identified as primary drivers behind this unprecedented warming trend.

    Mark McCarthy, the Met Office’s Head of Climate Attribution, emphasized the broader implications: ‘While not every subsequent year will necessarily establish new records, the accumulated evidence from both direct weather observations and sophisticated climate modeling unequivocally demonstrates that human-induced global warming is fundamentally altering the United Kingdom’s climate profile.’

    This national phenomenon reflects wider global patterns. The World Meteorological Organization concurrently reported that the past decade constitutes the warmest ten-year period in recorded history. Similarly, the European Union’s Copernicus Climate Change Service projects that 2025 will likely rank as either the second or third warmest year globally in modern datasets, following 2024 which established itself as the hottest year worldwide and particularly affected Europe—the planet’s most rapidly warming continent.

  • China’s ‘artificial sun’ experiment finds way to break fusion plasma density limit

    China’s ‘artificial sun’ experiment finds way to break fusion plasma density limit

    In a landmark achievement for nuclear fusion research, Chinese scientists have successfully surpassed the longstanding plasma density limit using the Experimental Advanced Superconducting Tokamak (EAST), China’s pioneering ‘artificial sun’ facility. This breakthrough, published in Science Advances on January 2, 2026, represents a critical advancement toward practical nuclear fusion energy.

    The international research collaboration, led by the Institute of Plasma Physics at the Hefei Institutes of Physical Science (Chinese Academy of Sciences) in partnership with Huazhong University of Science and Technology and France’s Aix-Marseille University, has developed a revolutionary theoretical model explaining plasma-wall interactions. Their research identified radiation instability triggered by boundary impurities as the fundamental mechanism behind the previously impenetrable density barrier.

    Tokamak devices, which use powerful magnetic fields to contain superheated plasma in a toroidal configuration, have long been constrained by this density limitation. When approaching this threshold, plasma would become unstable, escape magnetic confinement, and release dangerous energy bursts capable of damaging reactor components.

    The research team’s innovative approach enabled experimental manipulation of plasma beyond conventional limits, guiding it into a previously theoretical ‘density-free zone.’ This marks the first experimental verification of such a stable high-density plasma state in tokamak history.

    This scientific milestone provides both crucial theoretical understanding and practical methodology for achieving sustained high-density plasma operation—a fundamental requirement for viable fusion power generation. The breakthrough significantly advances prospects for developing clean, virtually limitless fusion energy by addressing one of the most persistent challenges in magnetic confinement fusion technology.

  • Blue Moon in UAE skies? What 2026 has in store for residents

    Blue Moon in UAE skies? What 2026 has in store for residents

    The United Arab Emirates is poised for an extraordinary year of astronomical events throughout 2026, with multiple supermoons and prolific meteor showers set to grace the night skies. This celestial spectacle offers both amateur stargazers and professional astronomers unprecedented opportunities for cosmic observation.

    The year commences with the Wolf Supermoon on January 3rd, coinciding strategically with the peak of the Quadrantids meteor shower. This dual phenomenon creates a remarkable viewing opportunity, though the supermoon’s brightness may partially obscure the meteor display.

    A particularly noteworthy event occurs on May 31st with the appearance of a Blue Micromoon. Contrary to its nomenclature, this phenomenon doesn’t manifest with blue coloration but represents the second full moon within a single calendar month. This micromoon will appear marginally smaller and less luminous than typical full moons due to its orbital positioning at apogee—the farthest point from Earth in its elliptical path.

    The lunar exhibitions continue with the Beaver Supermoon emerging after a ten-month interval, followed by the Cold Supermoon in December. The latter event holds special significance as it will be the closest lunar approach to Earth since 2019, resulting in the year’s most brilliant full moon presentation.

    The meteor shower calendar features several highlight events:

    The Quadrantids (January 3-4) initiate the celestial schedule with an impressive rate of 120 meteors hourly, best observed during pre-dawn hours.

    The Lyrids (April 22-23) offer a more modest display of 15-20 meteors hourly but occasionally produce spectacular fireballs surpassing Venus in luminosity.

    The Perseids (August 12-13) provide one of the most reliable and popular meteor displays with approximately 100 meteors hourly during summer nights.

    The Geminids (December 13-14) conclude the annual meteor schedule with the most intense performance, generating 120-150 multicolored meteors hourly and frequently producing brilliant fireballs.

    Additional meteor showers including the Orionids (October 21-22) and Leonids (November 17-18) will further enhance the year’s astronomical offerings, ensuring consistent celestial entertainment for UAE residents and visitors alike.

  • New discovery may challenge theory Vikings built first Irish towns – researcher

    New discovery may challenge theory Vikings built first Irish towns – researcher

    A groundbreaking archaeological discovery at Brusselstown Ring in Ireland’s Wicklow Mountains is fundamentally reshaping our understanding of ancient settlement patterns in prehistoric Britain and Ireland. Research led by Dr. Dirk Brandherm from Queen’s University Belfast has revealed what appears to be the largest nucleated settlement ever documented from prehistoric times in the region, dating back approximately 3,200 years to the Late Bronze Age.

    The extensive survey work, utilizing advanced aerial photogrammetry and mapping techniques, has identified more than 600 suspected house platforms within the massive hilltop enclosure. This settlement complex spans multiple hilltops—a rare feature among European hillforts—with defensive ramparts encircling both Brusselstown’s summit and the adjacent Spinas Hill. The distribution shows 98 structures within the inner enclosure and over 500 located between the dual defensive walls.

    Recent test excavations conducted between August and September 2024 by a team including PhD researcher Cherie Edwards and Dr. Linda Boutoille have provided critical insights into the settlement’s chronology and complexity. The evidence indicates primary occupation during the Late Bronze Age, with some structures showing continued use into the Early Iron Age. The discovery of a sophisticated stone-lined, boat-shaped chamber—potentially a water cistern fed by an uphill stream—adds another layer of architectural sophistication to the site.

    The scale and density of Brusselstown Ring challenge previous archaeological assumptions that Bronze Age settlements consisted primarily of small hamlets with one to five dwellings. This discovery dwarfs the previously largest known settlement at Corrstown, Northern Ireland, which contained approximately 74 roundhouses. The presence of structures of varying sizes (4-12 meters in diameter) suggests possible social or economic stratification, though further analysis is required to confirm this hypothesis.

    Published in the peer-reviewed journal Antiquity, these findings potentially rewrite the urban history of Ireland, suggesting the existence of proto-urban settlements some 2,000 years before Viking influence in the region. Future research will focus on confirming the cistern’s function and dating, detailed analysis of roundhouse structures, and establishing a comprehensive chronology of the enclosure elements.

    Watch: Stunning celestial events that lit up the skies in 2025

    The year 2025 has proven to be an extraordinary period for astronomical enthusiasts worldwide, featuring a succession of breathtaking celestial phenomena that transformed night skies into cosmic theaters. This remarkable series of events provided both amateur stargazers and professional astronomers with unprecedented opportunities to witness the universe’s grandeur.

    Among the most anticipated events were the periodic meteor showers, which delivered particularly intense displays this year. The Perseids in August and Geminids in December exceeded expectations with meteor rates reaching up to 120 visible streaks per hour under optimal conditions. These cosmic light shows resulted from Earth’s orbit intersecting with debris trails left by comets Swift-Tuttle and 3200 Phaethon respectively.

    The lunar calendar similarly impressed with multiple supermoons occurring throughout the year. These occurrences, when the full moon coincides with perigee (the moon’s closest approach to Earth), created spectacular visual displays with the lunar disk appearing approximately 14% larger and 30% brighter than typical full moons. The September supermoon was particularly notable for its coincidence with lunar perigee, making it the most dramatic lunar display of the year.

    Additional phenomena included planetary conjunctions where Venus, Mars, and Jupiter appeared to cluster in unusual celestial formations, providing exceptional photographic opportunities. The year also featured a partial solar eclipse visible across North America and a penumbral lunar eclipse observable from Europe and Africa.

    Astronomical organizations worldwide reported increased public engagement with night sky observation, with many communities hosting special viewing events. The accessibility of these events—requiring no special equipment beyond the naked eye—contributed to their widespread appeal, fostering greater public appreciation for astronomical science and the natural wonders of our universe.
