POSTECH-Led Team Develops AI Framework Accounting for Hidden Defects in Metal 3D Printing.

Professor Dong Soo Hwang’s team at POSTECH identifies the marine biological mechanism for packaging and delivering adhesive materials as nanocondensates.

As semiconductor scaling pushes beyond 3 nm, backside power-delivery networks become essential to ease wiring congestion. A new study in Engineering introduces a ruthenium-based nano through-silicon via technology paired with an all-dry SOI wafer thinning process. The scheme delivers low-resistance, highly reliable interconnects with precise wafer uniformity, offering a practical route to efficient 3D integrated circuit design.

Childhood epilepsy lacks reliable non-invasive biomarkers for precise diagnosis. A new study in Engineering reveals that N-glycans on serum extracellular vesicles act as a promising liquid-biopsy signature. Researchers optimized extracellular vesicle isolation and used mass spectrometry combined with machine learning to identify 47 key glycans that clearly distinguish healthy children from those with focal or generalized epilepsy, offering a new path for better clinical detection and monitoring.
