Low earth orbit (LEO) mega-constellations, characterized by dense satellite coverage and low transmission latency, have substantial advantages in global communications, earth observation, and disaster forecasting. Compared to traditional constellations with simple configurations, mega-constellations have a large number of nodes and complex satellite interaction relationships and are oriented to vast global missions. As a result, when the traditional ground-based centralized management mode is applied to a mega-constellation, the ground station suffers from an explosive growth of control load and struggles to achieve the efficient, timely, and orderly operation of the mega-constellation. Therefore, it is necessary to adjust the management architecture to partially transfer the on-ground management mission to on-board management mission. Clustering satellites into multiple management domains and implementing unified management within each domain is an effective method for realizing on-board management of mega-constellations. Existing studies on the construction of satellite management domains have focused on some specific indicators, such as spatial distribution uniformity, network control latency, and controller load. Considering the highly dynamic motion of the mega-constellation, a fixed management domain construction will inevitably lead to frequent updates of the management architecture, thereby increasing the burden of on-board management. Thus, more stable strategies for constructing and updating the management domain need to be explored to reduce the frequency of management architecture updates over extended mission periods.

A research paper by scientists at Cortical Labs investigate the complex network dynamics of in vitro neural systems using DishBrain, which integrates live neural cultures with high-density multi-electrode arrays in real-time, closed-loop game environments..

New research highlights how “super users” are shaping the future of virtual care through best practices that streamline workflows and improve patient adoption.

A research paper by scientists at the Capital Medical University evaluated sex differences in stroke recurrence among patients with symptomatic intracranial atherosclerotic stenosis (sICAS) and assess the efficacy of remote ischemic conditioning (RIC) in the RICA (chronic remote ischemic conditioning in patients with symptomatic intracranial atherosclerotic stenosis) trial.

The new research paper, published on Jun. 6 in the journal Cyborg and Bionic Systems, evaluated 3,033 sICAS patients across 84 Chinese stroke centers, with a median follow-up of 3.5 years. The findings highlight the need to consider sex in clinical decision-making for RIC administration.

In the past few years, rapid development has been witnessed in spacecraft formation to complete complex missions instead of the traditional single spacecraft. Spacecraft formation refers to a spatial distribution of a group composed of 2 or more spacecraft without physical contact. Those who join in the formation are called member spacecraft. There exists certain communication relationship between member spacecraft. The spacecraft formation is able to complete the tasks related to the target cooperatively through the collaborative control strategies. The formation offers low cost, strong reliability, and high flexibility in comparison to a single spacecraft for executing the mission. This has garnered considerable attention and warrants investigation. However, little research has discussed spacecraft formation to surround a noncooperative target with unknown dynamics. It is still challenging for the surrounding control to enclose the target with unknown dynamics that refers to the target’s orbit maneuver.In the past few years, rapid development has been witnessed in spacecraft formation to complete complex missions instead of the traditional single spacecraft.

The World Institute of Kimchi (President: Hae Choon Chang), a government-funded research institute under the Ministry of Science and ICT, has confirmed in a new study that bacteriophages, which were previously considered a ‘nuisance’ during the process of food fermentation, actually play the role of key helpers that facilitate the survival of lactic acid bacteria (LAB).

Silicon, aluminium and lithium are the most critical raw materials on the planet. Their scarcity and the complexity of extracting them could hinder the development of technologies that are key to the green transition. This is one of the main conclusions of a study by the INGENIO Institute, a joint centre of the Spanish National Research Council (CSIC) and the Universitat Politècnica de València (UPV), in collaboration with the University of Rome, the Universitat de València and the University of London.
