Large-scale programmable logic array achieves complex computations

Researchers developed a large-scale optical programmable logic array that can execute complex models like Conway's Game of Life, marking a significant advancement in optical computing. The array uses parallel spectrum modulation to achieve an 8-input system, significantly expanding the capabilities of optical logic operations.

Cellular automaton model predicts how hair follicle stem cells regenerate

A new cellular automaton model has successfully predicted how hair follicle stem cells regenerate, shedding light on the mechanisms behind alopecia. The study suggests that improving the environment around hair follicles may be a more effective approach to regrowing hair than implanting stem cells.

Experiment Demonstrates Transistorless Funtional Logic Gate

University of Notre Dame researchers have successfully demonstrated a functioning transistorless logic gate using quantum-dot cellular automata (QCA) technology. The device consists of four quantum dots connected in a ring by tunnel junctions, enabling digital data to be encoded in the positions of only two electrons.

Garmin GPSMAP 67i with inReach

Garmin GPSMAP 67i with inReach provides rugged GNSS navigation, satellite messaging, and SOS for backcountry geology and climate field teams.

Shrinking Information Storage To The Molecular Level

The team, led by Gregory L. Snider, has successfully demonstrated a transistorless approach to computing using quantum dots. This technology could lead to the development of smaller, faster, and more powerful computers with increased storage capacity, potentially replacing conventional microelectronic devices.
