DNA's information density is staggering: about 215 million gigabytes can theoretically be stored in a single gram. \"Usually, it takes more power to store more information. Our device consumes 100 times less power and storage capacity is higher than traditional storage devices,\" said Penn State research professor Bed Poudel.\n\nThe team, which includes postdoctoral researcher Kavya S. Keremane and research professor Neela H. Yennawar, computationally designed short synthetic DNA sequences engineered for specific electronic functions and paired them with the perovskite material already used in solar cells and lasers. The researchers see the biology-electronics hybrid as a path toward far more energy-efficient neuromorphic computing and AI data centers, where power draw has become one of the industry's biggest bottlenecks."}}
