Each year in the U.S., more than 300,000 people die from sudden cardiac arrest, a condition in which the heart's electrical system malfunctions without warning. The medical emergency can kill both high-risk older adults and young athletes with no history of heart issues, and whil

To treat or manage various heart, gastrointestinal and neurological conditions, including arrhythmias, heart block, gastroparesis, epilepsy and some nerve injuries, doctors rely on a technique known as electrical stimulation. Electrical stimulation entails the delivery of small e

The environment experienced by young zebrafish influences both the shape and electrical activity of the neurons in the eye, which affects subsequent behavior.

The human brain contains billions of neurons, specialized nerve cells that communicate with each other via electrical and chemical signals. Every neuron is made up of its body (i.e., soma), where most cellular processes occur; a long projection called an axon that sends signals t

It's a fact of life that the electrical activity of neurons will vary during the same task, even when the ultimate outcome is the same. A new study shows that a lot of ongoing fluctuations in the brain's activity can be explained by the influence local electric fields exert on th

Researchers at Weill Cornell Medicine and Birkbeck, University of London, have identified a site where a commonly used anesthetic binds to sodium ion channels, revealing a molecular mechanism that may explain how these drugs dampen communication between neurons. Ion channels are

Retailer says sharp rise in fan sales over the latest heatwave weekend left stores scrambling to source stockBusiness live – latest updatesThe boss of Currys has said supplies of air conditioning and fans are “tight” ahead of another UK heatwave, expected next week, after a boom

Shoppers urged to seek quality products or alternatives as data shows demand surpassing last year’s totalBritons are expected to buy nearly 8m mini fans this year as they are “surging on to the market” in the hot weather – but almost half of those are expected to be low-quality p

Supporters are told to stay in their seats as an electrical storm approaches the Azteca Stadium before Mexico v England in the last 16 of the World Cup.

What does an electrician do? Electricity powers the world, and electricians are the ones who get it where it needs to go. An electrician is an expert who is trained to make sure electrical systems and equipment are installed safely and working correctly. Electricians are involved

Stealthy startup Arcturus uses lasers to infuse carbon nanomaterials into copper, dramatically improving its ability to conduct electricity.

Scientists from the University of Manchester have shown how a plasma-based approach, using nonthermal plasma—an electrically energized gas often described as the fourth state of matter—can prevent catalyst deactivation in a key hydrogen production reaction, maintaining stable per
