Using sound waves to image nanostructures

The potential of an ultrafast form of transmission electron microscopy to measure sound waves in nanostructures has been demonstrated by three RIKEN physicists. This could help realize a high-resolution imaging method that ...

Method uses radio signals to image hidden and speeding objects

Researchers at the National Institute of Standards and Technology (NIST) and Wavsens LLC have developed a method for using radio signals to create real-time images and videos of hidden and moving objects, which could help ...

Seeking 'soundwaves' in the superfluid order parameter

A Swinburne University of Technology study published this week examines the propagation of energy as sound waves in a quantum gas, revealing for the first time strong variations in the nature of the sound wave as a function ...

Tic toc: Why pendulums swing in harmony

Almost 350 years ago, Dutch inventor and scientist Christiaan Huygens observed that two pendulum clocks hanging from a wall would synchronise their swing over time.

Nerve impulses can collide and continue unaffected

According to the traditional theory of nerves, two nerve impulses sent from opposite ends of a nerve annihilate when they collide. New research from the Niels Bohr Institute now shows that two colliding nerve impulses simply ...

TWIPS -- sonar inspired by dolphins

Scientists at the University of Southampton have developed a new kind of underwater sonar device that can detect objects through bubble clouds that would effectively blind standard sonar.

Golden Nanotubes Detect Tumor Cells, Map Sentinel Lymph Nodes

(PhysOrg.com) -- Biomedical researchers at the University of Arkansas in Fayetteville and the University of Arkansas for Medical Sciences (UAMS) in Little Rock have developed a special contrast-imaging agent made of gold-coated ...
