Low-Power Artificial Neurons

Researchers created the first artificial neurons that can directly interface with living cells. They run at voltages close to natural neurons and use protein nanowires from electricity-producing bacteria, making devices unusually energy efficient. For people with Amyotrophic lateral sclerosis (ALS), this could pave the way for ultra-low-power brain-computer interfaces and wearables that talk to the body without bulky amplifiers, offering new hope for easier communication and control.
