Physicists in Japan have for the first time generated beams of electrons displaying the fundamental physical property of orbital angular momentum. Like light beams before, these electron beams have ...

Researchers from the Georgia Institute of Technology offer a new method to disrupt spiral waves that uses less energy and that may be less painful than traditional defibrillation.

Electrical signals tell the heart to contract, but when the signals form spiral waves, they can lead to dangerous cardiac events like tachycardia and fibrillation. Researchers are bringing a new ...

Back to front: simulation showing colliding spiral wave-front and wave-back A mechanism that could break up potentially deadly spiral waves in heart tissue has been identified in simulations done by a ...

The late 20th and early 21st century have seen a revolution in the study of light. Far from the old days of seeing things dimly through microscopes, we are now in the position to freeze light, use it ...

A type of spiraling wave has been busted for disorderly conduct. Spiral waves are waves that ripple outward in a swirl. Now scientists from Germany and the United States have created a new type of ...

MONTREAL, CANADA (February 5, 2002)--Who says physicists don't have heart? In an effort to study the factors that lead to fatal cardiac rhythms, a team of Canadian researchers has shown that the ...

Researchers offer a new method to disrupt spiral waves that uses less energy and that may be less painful than traditional defibrillation. A spiral wave of electrical activity in the heart can cause ...
