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

Researchers have discovered a brain activity pattern that can predict which people with mild cognitive impairment are likely ...

Scientists at the Carney Institute for Brain Science have discovered specific patterns of electrical signals in the brain that may help forecast whether a person will go on to develop Alzheimer’s ...

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.

The constant, energy-driven motion inside living cells may generate electricity in a way no one fully recognized before.

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 ...

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), ...

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 ...

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 ...
