Existing three-dimensional (3D) neuronal culture technology has limitations in brain research due to the difficulty of precisely replicating the brain's complex multilayered structure and the lack of a platform that can simultaneously analyze both structure and function. A KAIST research team has successfully developed an integrated platform that can implement brain-like layered neuronal structures using 3D printing technology and precisely measure neuronal activity within them.

Kyoto, Japan -- Respiratory infections such as COVID-19 have been responsible for numerous pandemics and have placed a substantial burden on healthcare systems. Such viruses can cause significant damage to our lungs, especially to the proximal region, or airway, and distal region, also known as the alveoli.

The responses of different lung regions to such infections are varying and complex, so accurately replicating them using traditional models, such as animals and simple in vitro systems, poses a challenge.

To solve this problem, a team of researchers at Kyoto University has developed a micro physiological system, or MPS, capable of emulating different regions of human lungs. Specifically, their device can simulate the airway and alveoli to investigate viral pathologies. Coupled with isogenic iPSCs, the team is preparing for more personalized and accurate treatment of respiratory diseases.

To address these questions, a research team from Mansoura University, the Agricultural Research Center, and the University of Reading conducted a study in the agricultural provinces of Dakahlia, Giza, and Minya. The study involved 300 farmers using four types of plastic agriculture systems: open-field films, low tunnels, high tunnels, and net houses. Through stratified random sampling and face-to-face interviews, the team analyzed plastic usage characteristics, disposal methods, recycling barriers, and key motivations. The article was recently published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025621).
