The Aurora Borealis, or Northern Lights, shines above Bear Lake, Eielson Air Force Base. Find out about the physics behind this phenomenon.
These antennas could be used in devices that use light in place of the electrical signals.
Physicists have made what they believe to be the first true single molecule transistor.
In 1959 the Aharonov-Bohm effect took its place as a legitimate demonstration of unexpected physics in the quantum world.
Scientists model the scenario in which Earth's magnetic field switches poles.
Spin ice is like magnetic ice and physicists have made analogies of magnetic monopoles in spin ice.
What might look like the top and bottom of a limestone cave, may actually revolutionize the world of tiny electronics.
The world’s first superconducting magnet, consisting of a wire coil made of lead, was manufactured in the Leiden Physics Laboratory in 1912.
This image shows a map of the electrical characteristics of a topological insulator, providing information that is helping physicists to better understand how these new materials work.
High power laser pulses create shock-waves and bubbles in plasma.
This spectroscopic image shows what are called microwave-frequency magnetic resonances of an array of parallel, metallic thin film nanowire "stripes". The peak in the center reflects resonances occurring at the stripe edges. The strong horizontal bar of violet, black, and white, is due to resonances in the body of the stripes.
Red and green dye reveals the turbulent fluid flows from the magneto hydro dynamic propulsion device.
Sparks branch for the same reason that coral reefs and snowflakes do, according to new computer simulations.
A spark flying between a metal doorknob and your hand is an intricate chain of electrical events.
Electrons don't normally know one direction from another, so researchers were perplexed a few years ago when they found a cold plane of electrons suddenly choosing to conduct many times better in one direction than in the perpendicular one.
