What happens inside the carnivorous plant Venus Flytrap when it catches an insect? New technology has led to discoveries about the electrical signalling that causes the trap to snap shut.

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Human beings and other animals send electrical signals via the central nervous system. The Venus flytrap, which lacks such a nervous system, also sends rapid electrical impulses, which are generated ...

Electrical signalling plays a pivotal role in how plants perceive and respond to their environment. Rapid electrical impulses, including action potentials (APs) and slower variation potentials (VPs), ...

A new skin-like sensor developed by an international team led by researchers at Penn State could help doctors monitor vital signs more accurately, track healing after surgery and even help patients ...

Today’s computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to run programs and process information, computers rely on electricity. Each ...

Qubits -- the fundamental units of quantum information -- drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely ...
