An electric field describes the region of space extending from a charged particle in which another charged particle experiences a force related to its charge. Electric fields surround all charged particles. Surrounding every charged particle there is a...

An electric charge in a uniform external electric field will feel a force due to that field given by, F = qE, where F is the force, q is the charge and E is the external electric field (i.e. the charge is not affected by its own electric field.). This...

In physics, the space surrounding an electric charge or in the presence of a time-varying magnetic field has a property called an electric field (can also be equated to "Electric Flux Density"). This electric field exerts a force on other electrically...

A team of researchers at Ohio State University's Dept. of Food Science and Technology are developing the technique for using pulsed electric field for commercial food sterilization. The technology is built on inactivating microorganisms that cause food to spoil through the use of electric...

Pulsed Electric Fields (PEF) as a pasteurisation method is finally ready for commercial application. The first installation will appear on the market within a year. This preservation method is milder than heating, hardly affects product quality and costs only 0.02 more per litre...

Scientists are testing seasickness patches and other surprising options in a challenging search for new ways to treat the crushing depression and uncontrolled mania of bipolar disorder.Also called manic-depression, it's an illness that can rip careers and marriages apart and drive people to suicide. And...

Scientists are casting a wide net to find better treatments for the crushing depression and uncontrolled manias of bipolar disorder, and some approaches they're testing seem pretty surprising.Like skin patches that prevent seasickness. Or a drug that fights Lou Gehrig's disease. And then there's a...
