Random-pattern skin flaps are widely used to repair tissue defects, but surgeons still face a difficult question after reconstruction: which flaps will survive and which will fail?

After a stroke, nearly half of patients struggle to swallow – a dangerous condition called post-stroke dysphagia (PSD) that can lead to malnutrition, pneumonia, or even death. 

Korean researchers have secured flexible electronic skin technology that can be fabricated directly in the field. This achievement has further increased the feasibility of commercializing electronic skin for use in various fields, including robots and wearable devices. Electronics and Telecommunications Research Institute (ETRI) announced that, in collaboration with the research team of Professor Ahn Jun Seong from the Department of Control and Instrumentation Engineering at Korea University's Sejong Campus, it has developed an in-situ process-based electronic skin fabrication technology capable of producing large-area multimodal sensors without a cleanroom, a dedicated semiconductor clean-processing facility.

Chinese researchers have developed a cost-effective strategy for enhancing microalgae cultivation using fermented agricultural waste. The study demonstrates that an optimized fermented agricultural hydrolysate can increase the marine diatom Chaetoceros muelleri cell density by 2.56-fold compared to standard medium.

A research team from Jiangnan University has developed an engineered Escherichia coli strain capable of producing orotic acid at unprecedented levels using an innovative antibiotic-free plasmid stabilization system. The study reports a final titer of 150.48 g/L with a yield of 0.63 g/g glucose in fed-batch fermentation.
