Researchers report an insulator made of two conductors

Ohm's law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the material—the negatively ...

New technique illuminates DNA helix

Cornell researchers have identified a new way to measure DNA torsional stiffness—how much resistance the helix offers when twisted—information that can potentially shed light on how cells work.

Fluorescent nanodiamonds successfully injected into living cells

As odd as it sounds, many scientists have attempted to place extremely small diamonds inside living cells. Why? Because nanodiamonds are consistently bright and can give us unique knowledge about the inner life of cells over ...

How to untie magnetic nano-knots

Skyrmions—tiny magnetic whirls that appear in certain combinations of materials—are considered promising information carriers for future data storage. A research team from RWTH Aachen University, Kiel University, and ...

Melting a crystal topologically

The introduction of topology, a branch of mathematics focusing on the properties of 'knots,' into physics has inspired revolutionary concepts such as topological phases of matter and topological phase transitions, which resulted ...
