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 ...

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.

Researchers at the University of Warwick have found bacteria can be detected in minutes by zapping them with electricity. Scientists at the university in the United Kingdom discovered healthy bacteria ...

Electrical signals commonly occur in plants in response to various environmental changes and have a dominant function in plant acclimation. Recently, a research team from Zhejiang University in China ...

A new study found that deep sleep weakens breathing brain timing in movement circuits and changes internal brain ...

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 ...

Epithelial conversation An epithelial cell-coated microelectrode array with 60 precisely placed electrodes detects the minute electric signals generated when the cells are injured. (Courtesy: UMass ...

A new study has furthered our understanding of plant evolution by tracking the origins of electrical signaling components that plants developed to communicate and adapt to life on land. A study led by ...

Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal ...

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 ...
