Mechanical engineers have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as 'acoustic tweezers, ...

DURHAM, N.C. - Mechanical engineers at Duke University have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...

NEW YORK, March 13, 2023 — When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored ...
