Nature Signals

Life already runs on electricity.

Long before we built circuits, nature perfected bioelectric systems. Explore the organisms, ecosystems, and phenomena that prove electricity is the language of life.

I hate things in my pockets. That instinct โ€” not grand philosophical acceptance, but the simple, personal desire for a better solution โ€” is how the merger of humanity and technology will actually happen.

Bioelectronics startup BackBeat Medical closed a $95M Series C to scale its implantable cardiac pacemaker-based system that reduces blood pressure without drugs โ€” through precisely timed electrical pulses.

Ion channels are the hardware of bioelectricity โ€” protein pores that open and close to control the flow of charged atoms across cell membranes. Understanding them is the key to understanding everything from pain to heartbeat.

The Ghost Knifefish Navigates in Complete Darkness Using a Self-Generated Electric Field

Apteronotus albifrons ยท Weakly Electric Fish ยท Amazon Basin
Emitting a continuous 1kHz electric field from its body, the black ghost knifefish builds a three-dimensional map of its environment โ€” detecting objects, prey, and rivals by how they distort its personal electromagnetic bubble.
