A groundbreaking Chinese innovation in materials science has received global recognition, with Physics World naming the development of ultrathin metal films as one of 2025’s top 10 scientific breakthroughs. The prestigious accolade highlights China’s emerging leadership in advanced materials research and development.

The pioneering research, conducted by the Institute of Physics at the Chinese Academy of Sciences, has successfully produced the world’s first single-atom-layer metal materials. These revolutionary materials measure at the angstrom scale—approximately one-millionth the thickness of standard A4 paper and one-200,000th the diameter of a human hair.

This achievement represents a significant milestone in materials science, particularly considering that non-layered metals constitute approximately 80% of the periodic table’s elements. Previously, scientists considered these metals nearly impossible to reduce to single atomic layers due to their tightly bonded three-dimensional atomic structures. While hundreds of two-dimensional materials have been created since graphene’s discovery in 2004, all previously originated from layered crystals.

The research team overcame this fundamental challenge through an innovative van der Waals squeezing technique. This method utilizes molybdenum disulfide as an anvil to compress two-dimensional metals including bismuth, tin, lead, indium, and gallium.

The resulting two-dimensional metals exhibit exceptional properties, including remarkable environmental stability with no performance degradation observed for over one year. They feature nonbonding interfaces that enable researchers to better explore the materials’ intrinsic properties while demonstrating higher room-temperature conductivity than conventional alternatives.

These advanced materials are expected to enable macroscopic quantum phenomena and serve as core components for numerous technological innovations. Potential applications include low-power transistors, high-frequency electronic devices, and ultrasensitive detection systems that could transform multiple industries.

Physics World’s annual list is widely regarded as one of the most authoritative recognitions in the scientific community. Selection criteria require demonstrated scientific importance, substantial advancement of knowledge frontiers, successful integration of theory and experimentation, and significant attention from physicists worldwide. This achievement marks the seventh time Chinese-led research has been honored since the list’s establishment in 2009.

In a landmark demonstration of neurotechnology, a completely paralyzed Chinese patient has achieved unprecedented independence through an advanced brain-machine interface (BMI) system. The patient, a man in his thirties, successfully manipulated a power wheelchair and commanded a robotic assistance dog to retrieve deliveries using only neural signals.

The revolutionary BMI technology was surgically implanted in June 2025 through a collaboration between the Chinese Academy of Sciences’ Center for Excellence in Brain Science and Intelligence Technology and private sector partners. This sophisticated system translates neural activity into digital commands, enabling direct brain-to-device communication without requiring physical movement.

Clinical results demonstrate transformative improvements in daily living capabilities. The patient has reached levels of self-sufficiency, vocational engagement, and social interaction that were previously considered unattainable for individuals with high-level paralysis. This represents the most significant advancement in functional restoration for paralyzed patients since the development of neural prosthetics.

The technology’s successful real-world application signals a new era in assistive technologies and neurological rehabilitation. Medical experts highlight that this breakthrough extends beyond laboratory research, offering tangible solutions that dramatically improve quality of life for those with severe mobility impairments.

Researchers indicate that this achievement establishes new benchmarks for neural interface technology and paves the way for more sophisticated human-machine integration systems in the future.

In a landmark achievement for materials science, Chinese researchers have earned global recognition for creating the world’s first two-dimensional metals, an accomplishment long considered nearly unattainable. This groundbreaking work, led by a team at the Institute of Physics under the Chinese Academy of Sciences, has been selected among Physics World’s prestigious “Top 10 Breakthroughs for 2025.”

The research, published in the renowned journal Nature in March 2025, represents a quantum leap in materials science that could potentially propel the next stage of human technological advancement. Since the discovery of monolayer graphene in 2004, 2D materials have fundamentally transformed scientific understanding of material properties and driven unprecedented innovations in condensed-matter physics.

According to Professor Zhang Guangyu, the project’s lead scientist, creating 2D metals presented extraordinary challenges due to the strong metallic bonds between atoms that occur in all directions. “The metallic bonding nature made conventional approaches to 2D material synthesis ineffective,” Zhang explained. “We had to fundamentally rethink material fabrication at the atomic level.”

The research team pioneered an innovative atomic-scale manufacturing technique called the van der Waals squeezing method, which enabled the creation of diverse 2D metals including bismuth, tin, lead, indium, and gallium. These ultra-thin materials measure just one millionth the thickness of a standard A4 paper sheet and approximately one 200,000th the diameter of a human hair.

The implications of this breakthrough extend across multiple technological domains. These novel 2D metals could revolutionize numerous industries through ultra-micro low-power transistors, high-frequency communication devices, transparent display technology, ultra-sensitive detection systems, and highly efficient catalytic processes.

Physics World, the flagship publication of the Institute of Physics (the professional body for physics in the UK and Ireland), annually recognizes achievements that demonstrate significant scientific importance, advance the frontiers of knowledge, and attract broad attention from the global physics community. The selection criteria emphasize rigorous scientific validation, seamless integration of theory and experiment, and profound implications for future research and applications.

Archaeologists have made a groundbreaking discovery in Northwest China’s Shaanxi province, unearthing a vast network of 573 ancient stone cities that date back approximately 4,800 to 3,800 years. This extraordinary find, resulting from six years of intensive survey work in the Yulin region, fundamentally reshapes our understanding of early Chinese civilization patterns and challenges long-held historical paradigms.

The newly discovered urban centers, constructed between 2800 BC and 1000 BC, represent the largest and most sophisticated prehistoric stone city complex ever identified in northern China. According to Ma Mingzhi, associate researcher of Yulin’s cultural relics and archaeological survey team, these findings dramatically surpass previous records—before this survey, fewer than 200 prehistoric city sites had been documented nationwide, with only several dozen being stone constructions.

The architectural sophistication reveals a clearly stratified society with hierarchical urban planning principles. Higher-status inhabitants occupied central zones with more complex defensive walls, while outer areas housed those of relatively lower status. These settlements, strategically positioned along riverbanks, served multiple functions including military defense, residential settlement, and religious ritual. The Shimao site features particularly remarkable stone carvings depicting divine faces, dragons, and snakes, alongside noble burial grounds and structures believed to be ancestral temples.

This discovery effectively dismantles the traditional ‘Central Plains-centric theory’ of Chinese civilization development, demonstrating that northern Shaanxi served as a crucial cultural hub during the early Xia Dynasty (c. 21st-16th century BC). The scale of urbanization—with over 600 stone cities now identified across Shaanxi, Inner Mongolia, Shanxi, and Hebei provinces—corroborates ancient literary references to an ‘era of ten thousand states’ that historians previously considered potentially fictional.

Professor Han Jianye from Renmin University of China notes that the construction timeline coincides with the legendary Yellow Emperor era, suggesting the region served as both a cultural core and a defensive prototype for what would eventually become the Great Wall. The sites demonstrate clear evolutionary progression, with settlements expanding in scale, spatial layouts growing more complex, and construction techniques advancing significantly over centuries of continuous use.

Future research will focus on environmental support systems, handicraft production, regional economic development, and genetic analysis of population movements. These investigations promise to illuminate the material foundations that sustained this remarkable urban network and its interactions with contemporary ethnic groups, potentially rewriting our understanding of state formation processes in ancient East Asia.

Paleontologists have identified a colossal new dinosaur species that roamed the terrain of present-day Chongqing approximately 160 million years ago during the Late Jurassic period. The monumental discovery, formally classified as Mamenchisaurus sanjiangensis, was detailed in a groundbreaking study published in the prestigious journal Scientific Reports.

The fossilized remains were originally unearthed in 2015 within Chongqing’s Hechuan district, a region situated at the convergence of the Jialing, Fujiang, and Qujiang rivers—a geographic feature that inspired the species’ nomenclature. With an estimated body length reaching 24 meters, comparable to the dimensions of a modern blue whale, this sauropod represents one of the most substantial dinosaur specimens ever recovered from the municipality.

Research led by Dai Hui of the Chongqing Institute of Paleontology revealed that although the newly identified species shares close phylogenetic relationships with Mamenchisaurus hochuanensis, meticulous analysis of skeletal structures confirmed its distinct taxonomic status. The remarkably preserved fossil assemblage includes an extensive series of cervical, dorsal, and caudal vertebrae, alongside pelvic elements and portions of the left limb.

This significant paleontological breakthrough emerged from the Upper Shaximiao Formation, a stratigraphic layer renowned for yielding numerous iconic Chinese dinosaur discoveries. The excavation and subsequent analysis mark a substantial advancement in Chongqing’s paleontological capabilities, providing crucial insights into sauropod diversification across East Asia during the Jurassic era. Mamenchisaurus sanjiangensis constitutes the eleventh novel dinosaur species identified in China throughout 2024, elevating Chongqing’s confirmed dinosaur species tally to fifteen.
