Can you imagine a future where wars are fought not with bombs and bullets but computer viruses and pacemaker shutdowns? Cyberware is unique in that it is not covered by existing legal framework and it often inspires more questions than...

Mathematician Steven Strogatz shows how flocks of creatures (like birds, fireflies and fish) manage to synchronize and act as a unit -- when no one's giving orders. The powerful tendency extends into the realm of objects, too.

Tissue engineer and TED Fellow Nina Tandon is growing artificial hearts and bones. To do that, she needs new ways of caring for artificially grown cells -- techniques she's developed by the simple but powerful method of copying their...

Today we're talking the heart and heart throbs -- both literal and those of the televised variety. Hank explains how your heart's pacemaker cells use leaky membranes to generate their own action potentials, and how the resulting...

Howcast - Learn about vagus nerve stimulation, or VNS, to treat epilepsy from Steve Wolf, MD and Patty McGoldrick, NP in this Howcast video.

As part of a routine health checkup, veterinarians at the San Diego Zoo discovered this little guy has an arrhythmia, or an irregular heart rhythm. See how they get him back to his usual active self.

Veterinarians at the San Diego Zoo discover a Tasmanian Devil has a heart condition, which results in a first-of-its-kind procedure.

They were only the second in the United States to perform this live-saving intervention.

Russian surgeons have successfully implanted a groundbreaking micro computer called the Electronic Heart Guardian, which monitors heart activity and delivers targeted electric impulses to normalize heart operation in case of...

Introducing a new experimental device, similar to a pacemaker for the stomach, that has shown promising results in helping overweight patients shed pounds. By delivering mild bursts of electrical current to the stomach muscle, the device...

Discover how doctors use electricity in the human body to stimulate and suppress muscles - and save lives. Physics - Electricity And Circuits - Learning Points. Electricity is a useful tool in medicine and saves lives. An electric shock...

This video is a brief overview of the history and advancements of pacemakers, highlighting their importance in revolutionizing medicine and improving the quality of life for patients with cardiac conditions. It discusses the early...

This video covers the structure and function of the heart, the double circulatory system, the associated blood vessels, pacemaker cells and the coronary arteries.

Benefits of Technology discusses the many ways that technology increases the quality of human life with a focus on health, communication, exploration, and learning.

Let's dive into the cardiac action potential and how it results in the contraction of the heart. We'll talk about the signal that starts at the SA node and spreads throughout the heart. We'll also get into the phases of depolarization,...

In this video, I talk about the pacemaker potential of the heart. We're going to dig into the SA and AV Nodes, how they work, and what happens when things go wrong.<br/>

Researchers in Barcelona and Slovakia have created a cylinder which is invisible to magnetic fields with potential military and medical applications. Placed inside a magnetic field the device has no effect on the field lines, showing...

In this video, we discuss how the electrical conduction system generates a pacemaker potential by viewing the action potential diagram.

Patients whose spinal columns had been severed in accidents can now walk again, thanks to an amazing medical invention.

This video showcases five unexpected anatomical abnormalities found during dissection of donated bodies. From a lung missing a lobe to an ovary enlarged by polycystic ovarian syndrome, the video provides an interesting and educational...
