In a recent study published in the National Science Review, researchers from China proposed an Open and Shared Sustainable Mega-Constellation (OSSMC) to address the critical issue of space sustainability. By integrating a novel "Sensors+Network+AI" (SNAI) satellite architecture and a "cloud-pool-terminal" (CPT) paradigm, the OSSMC is proposed for the development of space-based intelligence. Only 48,000 intelligent satellites can meet all kinds of service needs of global users, which provides a Chinese solution for building a community with a shared future for mankind in space systems.
Every three seconds, someone in the world develops dementia—a condition expected to nearly double in prevalence every 20 years, reaching 78 million cases by 2030. This rising tide poses profound medical, social, and economic challenges.
With the advancement of high-throughput sequencing technologies and precision medicine, researchers are beginning to uncover the complex biological mechanisms of dementia. These breakthroughs are paving the way for earlier detection, personalized interventions, and more effective strategies to slow disease progression.
The demand for deep human-machine fusion propels the development of artificial neuron. However, emulating the neuronal spiking in aqueous environments remains challenging. Inspired by the biocompatibility of metal-organic frameworks (MOFs), Zhao et al. reported a MOF neuron with biochemical perception for the first time. Based on the real neurotransmitter—dopamine (DA) mediation, the neuron not only emulated some sophisticated neuronal functions but also controlled peripheral equipment, providing a new perspective for artificial neuron development.
A recent study published in National Science Review analyzes a new type of solar energetic particle event with faster particles arriving later than slower ones. The analysis of such events reveals that the energetic particles are confined and accelerated to higher energy by interplanetary shocks through the diffusive shock acceleration mechanism, which results in the late release of high-energy particles. This study challenges the traditional picture and opens a new window for diagnosing the remote interplanetary shock from observed IVD structure.
This study delved into the pollution levels and spatiotemporal distribution characteristics of 31 endocrine disrupting chemicals in three marine protected areas and the adjacent coastal areas, evaluating their partitioning patterns, estrogenic potency, and potential ecological risks they posed.
Researchers at Nanjing University of Science and Technology (NJUST) developed PCA-3DSIM, a mathematically grounded enhancement to 3D structured illumination microscopy that improves resolution and stability by integrating physical modeling with statistical analysis, enabling clearer and more reliable super-resolution imaging in life sciences with broad implications for advancing biological discovery and precision medicine.
In the ongoing debate about the impact of trade openness on environmental sustainability, a new study titled "Trade Openness and Carbon Emissions Using Threshold Approach: Evidence from Selected Asian Countries" offers fresh insights. This research explores the nuanced relationship between trade openness and carbon emissions, providing valuable evidence from a selection of Asian countries. By employing a threshold approach, the study aims to uncover the conditions under which trade openness can either exacerbate or mitigate carbon emissions.
Slurry-based absorption–adsorption enables efficient ethane recovery from natural gas, reducing energy use while ensuring high purity and recovery in CH4/C2H6 separation.
