The study focuses on establishing normative values for left ventricular (LV) and left atrial (LA) size and function using three-dimensional echocardiography (3DE) among healthy Han Chinese adults. This prospective, multicenter research was conducted across various age groups and aimed to account for ethnic variations not covered by existing American Society of Echocardiography (ASE) and European Association of Cardiovascular Imaging (EACVI) guidelines. The investigation revealed significant differences in cardiac measurements when compared to global standards, underscoring the need for population-specific norms.

The research team led by Dr. Jeong Min Park from the Nano Materials Research Division at the Korea Institute of Materials Science (KIMS) has successfully developed a new high-performance metal 3D-printed alloy tailored for space environments.

Researchers at the Advanced Photon Source joined an international effort to study tiny fragments of a nearby asteroid. The specks of asteroid dust were collected from asteroid 162173 Ryugu by a Japanese space mission. The team discovered that Ryugu began its life in the outer solar system as part of a larger asteroid more than 4 billion years ago. Since breaking off from its larger parent, Ryugu slowly made its way to its current orbit within 60,000 miles of Earth.

An invention made from waste polystyrene that generates static electricity from motion and wind could lower power usage by recycling waste energy in air conditioners and other applications.

More than 25 million tonnes of single-use, polystyrene packaging materials are made globally each year, but only a tiny fraction is recycled – most of it goes to landfill once it has served its purpose.

The innovation by RMIT University in collaboration with Riga Technical University in Latvia helps address this waste challenge by finding a practical use for the material.

Ulcerative colitis (UC) is a chronic autoimmune disease that mainly affects the rectum and colon. The symptoms primarily include abdominal pain, diarrhea, and bloody stools. The incidence of UC continues to increase each year. Bear bile powder (BBP) is a well-known traditional medicine that remains in use due to its outstanding efficacy. This study aimed to elucidate the therapeutic effects and molecular mechanisms of BBP on dextran sulfate sodium (DSS)-induced UC.

Besides helping to collect samples or spot butterflies for research projects — non-professionals can now conduct actual laboratory work alongside professional researchers. Together with Danish high schools, the University of Copenhagen has shown that "extreme citizen science" doesn’t just strengthen student motivation for science, but also provides a unique contribution to the monitoring of Denmark’s marine environment.

Researchers are trying to overcome the ephemeral nature of peptides, which might otherwise be powerful medicine. A University of Virginia team has found one approach.

New power system architecture will greatly increase the difficulty and vulnerability of the power system operation and control. The high integration of information and communication technology (ICT) promotes comprehensive information sharing, but it also highlights the urgency of establishing modeling and analysis methods for ICT-based power secondary systems. In this paper, simulation modeling methods for power secondary systems are proposed to achieve information sharing under interconnectivity and interoperability criteria. The smart substation secondary system with complex functional descriptions is taken as the research object. Firstly, a structural model of intelligent electronic devices (IEDs) is proposed that meets the interconnectivity requirements. Secondly, a functional model of IEDs with built-in algorithms for secondary business in power systems is proposed, as well as power communication protocol models that meets the interoperability requirements under IEC 61850 standard. Thus, through the state design in the process domain, the IED function in the node domain and data exchange between IEDs in the network domain can be achieved. Finally, taking a typical 220kV substation line current protection as an example, the entire process of protection setting modification and protection actions after a fault occurred are simulated by correlating the operating status of the power primary system, verifying the correctness of the proposed simulation models.
