    Scientists pioneer first-ever genealogy for volcanoes beneath Antarctic ice

    In a groundbreaking polar research achievement, an international scientific consortium has developed the first comprehensive genealogical archive of subglacial volcanoes concealed beneath Antarctica’s massive ice sheets. Designated as ANT-SGV-25, this pioneering catalogue documents 207 known volcanic formations, providing an unprecedented systematic reference for understanding these hidden geological features.

    The research initiative was spearheaded by China’s Polar Research Institute (PRIC) in collaboration with Zhejiang University, Fudan University, and the United Kingdom’s University of Exeter. The team synthesized existing scientific data to address longstanding observational challenges and resolution limitations that have historically hampered systematic study of these subsurface structures.

    According to lead researcher Cui Xiangbin of PRIC’s Center for Polar Ice & Snow and Climate Change Research, the volcanic inventory reveals significant morphological diversity. The documented volcanoes range dramatically in scale, with elevations spanning from 100 to 4,181 meters and volumes varying from 1 to 2,800 cubic kilometers. Their basal widths extend from 0.3 to 58 kilometers, with median slopes averaging approximately 8.1 degrees.

    The distribution pattern shows pronounced concentration within the West Antarctic Rift System, where crustal stretching and elevated geothermal activity create favorable conditions for volcanic formation. By contrast, only three volcanic structures have been identified in East Antarctica to date.

    This research breakthrough holds substantial implications for understanding ice sheet dynamics. Subglacial volcanoes significantly influence basal topography, promote ice melting through geothermal heat, regulate subglacial hydrological systems, and ultimately affect ice flow patterns and stability. The comprehensive parameter system established through computer vision technology and data integration enables detailed classification, origin analysis, and impact assessment of these geological features.

    The findings, published in the prestigious journal Earth-Science Reviews, represent a crucial public data resource for the global scientific community studying polar environments and climate change impacts.

    In a pioneering achievement for space biology, Chinese researchers have documented the first successful emergence of a butterfly from its chrysalis in Earth’s orbit. The breakthrough experiment, conducted aboard a miniature sealed ecosystem, provides unprecedented insights into biological adaptation to microgravity conditions.

    Chongqing University’s research team developed the specialized 8.3-kilogram payload that housed the butterfly chrysalis alongside pepper plants and microorganisms. Launched December 13, 2025, aboard the Kuaizhou-11 Y8 carrier rocket, the self-contained ecosystem maintained Earth-like conditions through carefully calibrated environmental controls.

    Chief designer Xie Gengxin explained the engineering innovations that made the experiment possible. ‘We overcame significant technical challenges, particularly magnesium alloy oxidation in high-humidity environments, to create a robust protective structure for this biological habitat,’ he stated.

    The spacecraft’s monitoring systems captured photographic evidence showing the butterfly adapting remarkably to weightlessness—moving within the capsule, resting on leaves, and fluttering its wings despite the absence of normal gravity. Telemetry data confirmed stable pressure, temperature, and humidity levels throughout the emergence process.

    This achievement represents more than insect development in space; it validates the viability of complex closed-loop life support systems for long-duration missions. The experiment successfully simulated Earth’s ecological cycles, with plants generating oxygen and potential food sources while microorganisms processed waste to maintain atmospheric stability.

    Researchers now turn their attention to evaluating the structure’s orbital endurance, component adaptability, and long-term sealing capabilities—critical factors for future deep-space exploration and potential extraterrestrial colonization efforts.

  • First amphibian footprints from Jurassic of Asia discovered in Beijing

    First amphibian footprints from Jurassic of Asia discovered in Beijing

    In a landmark paleontological breakthrough, researchers have confirmed the discovery of the first-ever Jurassic-period amphibian footprints found in Asia, located within Beijing’s Mentougou District. The extraordinary find, recently published in the esteemed journal Ichnos, was spearheaded by a team of Chinese scientists and originated from a chance discovery by a local elementary school student.

    The fossil evidence consists of a meticulously preserved pair of impressions—a forefoot and a hindfoot—etched onto a single stone slab estimated to be approximately 160 million years old. The tracks were identified on a roadside slope in Longquan town. According to Professor Xing Lida, a renowned dinosaur specialist from the China University of Geosciences in Beijing, the alignment, size, and spacing of the 1.5-centimeter-long prints indicate they were made by a single, small animal in motion.

    One impression is exceptionally well-defined, presenting a distinct fan-shaped morphology with four slender, pointed toes. To extract maximal detail from these diminutive traces, the scientific team employed advanced photogrammetric 3D modeling. This digital technique generated a high-fidelity three-dimensional model that unveiled subtle surface features imperceptible to the naked eye, providing a robust foundation for conclusive analysis.

    Through rigorous morphological comparison and quantitative skeletal-track correlation, the research team attributed the footprints to a salamander-like amphibian from the Middle Jurassic era. This discovery shatters previous records for the region, which were dominated by dinosaur and turtle tracks, effectively filling a critical void in the Asian vertebrate ichnological record.

    The implications extend far beyond a new species identification. These ancient tracks serve as a direct portal into the paleoecology of northern China, painting a picture of a lush, complex ecosystem where small, land-adapted amphibians thrived alongside ferns, ginkgos, and cycads in a lake-swamp environment.

    A particularly inspiring aspect of this scientific achievement is its origin. The crucial fossil was first spotted in early 2025 by Ni Jingchen, a young fossil enthusiast and elementary school student, during a exploratory outing. Professor Xing hailed this as a quintessential example of public participation in science, demonstrating that profound historical discoveries can sometimes lie in the most unassuming places, awaiting a curious and observant mind.

  • Chinese scientists achieve breakthrough in quantum computing with ‘Zhuangzi 2.0’

    Chinese scientists achieve breakthrough in quantum computing with ‘Zhuangzi 2.0’

    Researchers from the Institute of Physics of the Chinese Academy of Sciences and Peking University have made a groundbreaking advancement in quantum computing through their work with the sophisticated ‘Zhuangzi 2.0’ quantum processor. Their study, published in the prestigious journal Nature, demonstrates unprecedented control over quantum system stability—a capability that has previously eluded even the most powerful classical supercomputers.

    The team’s breakthrough centers on harnessing a phenomenon known as ‘prethermalization.’ This quantum equivalent occurs when qubits, upon receiving external energy, enter a brief but stable phase instead of immediately collapsing into chaos. During this critical window, information remains preserved and the system maintains order, much like ice lingering at 0°C while absorbing heat before transitioning to water.

    The researchers employed an innovative technique called Random Multipolar Driving to manipulate this quantum plateau. By carefully adjusting the rhythm and pattern of energy pulses sent into the 78-qubit chip, they gained the ability to extend or shorten this stable phase. This approach provides scientists with a controllable temporal shield—akin to solving a complex puzzle whose pieces constantly threaten to disintegrate—allowing for critical computations before the system ultimately decoheres.

    Dr. Fan Heng, corresponding author of the study, emphasized that this achievement represents more than mere qubit quantity advancement. ‘This breakthrough necessitates systematic research throughout the entire process,’ he stated, highlighting the integrated approach combining experimental work, numerical simulations, and theoretical analysis. The ‘Zhuangzi 2.0’ chip’s inherent quantum properties enabled real-time observation of these complex dynamics, providing insights previously impossible with classical computation.

    While 78 qubits may appear modest compared to conventional computing bits, their quantum interactions create complexity that grows exponentially with entanglement. This exponential scaling eventually creates simulation requirements that surpass the capabilities of even the most advanced silicon-based computing systems, marking a fundamental boundary between classical and quantum computational domains.

  • University makes breakthrough in low-dimensional antiferromagnet research, paving way for R&D of new-generation chips

    University makes breakthrough in low-dimensional antiferromagnet research, paving way for R&D of new-generation chips

    Researchers at Shanghai’s Fudan University have achieved a landmark advancement in low-dimensional magnetic materials that could fundamentally transform semiconductor technology. Published in the prestigious journal Nature, their study resolves a decades-old challenge in harnessing antiferromagnetic materials for practical computing applications.

    The research team from the State Key Laboratory of Surface Physics demonstrated unprecedented control over chromium thiophosphate (CrPS4), a layered antiferromagnetic material. Unlike conventional ferromagnets that power current data storage technologies, antiferromagnets maintain neighboring magnetic moments in opposing orientations, effectively neutralizing stray magnetic fields. This property enables superior stability and significantly higher data density potential.

    Professor Wu Shiwei, co-corresponding author of the study, explained their breakthrough: “We’ve developed techniques to precisely control and directly observe the magnetic state using our custom magneto-optical microscope. This satisfies the fundamental requirements for binary data operations that have eluded researchers until now.”

    The team’s most significant contribution involves expanding the classic theoretical model for ferromagnets to encompass antiferromagnetic behavior. Their modified framework predicts how these materials respond to external magnetic fields, with CrPS4 exhibiting an innovative “interlayer-locked” switching mechanism where all layers flip simultaneously rather than sequentially.

    This coordinated switching preserves system stability while maintaining antiferromagnets’ inherent advantages: faster state transition speeds and minimal energy consumption compared to traditional ferromagnetic materials. The researchers additionally established clear criteria for evaluating other antiferromagnetic materials, providing a roadmap for future semiconductor development.

    Industry analysts suggest this advancement could accelerate China’s progress in next-generation semiconductor technology, potentially reshaping global competition in information technology infrastructure. The breakthrough addresses critical limitations in current chip manufacturing as the industry pursues smaller, faster, and more energy-efficient devices.

    An international research consortium led by Beihang University has unveiled a groundbreaking bioelectronic patch technology that promises to revolutionize targeted therapeutic delivery to complex organs. Dubbed POCKET, this ultra-flexible device represents a paradigm shift from conventional systemic drug administration by conforming precisely to irregular organ surfaces like ovaries and kidneys.

    The innovation addresses a critical clinical dilemma: women with hereditary BRCA1 mutations currently face radical preventive surgery involving ovary and fallopian tube removal, resulting in permanent infertility. Existing viral vector gene therapies pose unacceptable risks of germline genome contamination, making them unsuitable for reproductive organs.

    Drawing inspiration from traditional paper-cutting artistry, the multidisciplinary team engineered a four-layer nanostructured patch achieving over 95% surface coverage on anatomically complex organs. The device integrates silver nanowire electrodes, a drug-loaded hydrogel reservoir, and precisely patterned nanopores created through femtosecond laser processing.

    When activated by low-voltage current, POCKET generates localized electric fields that temporarily create microscopic channels in cell membranes. This electroporation mechanism allows direct intracellular drug delivery with nearly 1,000-fold efficiency improvement over passive diffusion while preserving deeper tissue integrity.

    In preclinical models, the technology successfully delivered BRCA1 gene therapy exclusively to ovarian surface cells in mice, reducing cancer risk without compromising reproductive function. Additional trials demonstrated targeted anti-inflammatory delivery to transplanted kidneys, protecting renal function while eliminating systemic side effects associated with oral steroids.

    Co-corresponding author Chang Lingqian from Beihang University emphasized the platform’s adaptability for treating diabetes, retinal disorders, and rheumatoid arthritis. This physical delivery approach avoids genetic contamination risks while enabling precision targeting previously unattainable with conventional methods.

    The research, published in Cell on January 30, 2026, marks a significant advancement in bioelectronic medicine, potentially transforming treatment paradigms for sensitive and structurally complex organs throughout the human body.
