Researchers at King Abdullah University of Science and Technology (KAUST) have developed a novel authentication technology that enables digital devices to verify their identity using unique physical characteristics embedded in their hardware. Published in Nature Electronics, the system generates distinctive digital fingerprints through tiny laser devices, with no two lasers producing exactly the same light pattern. By combining these hardware fingerprints with artificial intelligence, the technology can rapidly and accurately authenticate devices while consuming minimal energy. The innovation could strengthen security across cloud computing, AI infrastructure, and large-scale networks of connected devices, offering a potential alternative to conventional password- and key-based authentication methods. Researchers are now exploring how the technology can be integrated into future computing and communications systems.

A research team at McMaster University has developed a targeted approach to treating inflammatory bowel disease (IBD) using bacteriophages, viruses that infect specific bacteria, to disarm harmful microbes without disrupting the broader gut ecosystem.
