Atomic-Scale Quantum Computing Breakthrough: Transistors Could Shrink Below 4 Nanometers

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a simulation-based method to predict the minimum scaling limits of transistors before quantum effects disrupt their operation. Using first-principles calculations applied to monolayer molybdenum disulfide (MoS₂), the team found that electron leakage can be suppressed at sizes below 4 nm, offering a critical design reference for next-generation semiconductor chips.

Octopus-Inspired Robotic Arm with 'Thinking Suckers' Developed by Italian Researchers for Deep-Sea Exploration

Researchers at the Italian Institute of Technology (IIT) have developed a bionic robotic arm modeled on the octopus, featuring distributed intelligence that allows each sucker unit to sense and respond to environmental changes autonomously—without relying on a central processor. Drawing on 500 million years of biological evolution, the design aims to overcome the limitations of conventional underwater robots operating in unpredictable currents, low visibility, and complex terrain.
