Plants are constantly under siege by pathogens, and their survival depends on precise internal defense strategies. 

In a recent study published in Engineering, researchers have unveiled a novel programmable spin-logic gate that operates without the need for initialization. By integrating spin-orbit torque (SOT) with an in-plane Oersted field generated by an Au line, this device can perform complete Boolean logic operations in a single step, offering a new approach for in-memory computing architectures. The findings highlight the potential for non-volatile spin-logic devices to enhance processing efficiency and scalability in future computing systems.
