A new method for obtaining high-resolution images of cells from low-resolution ultrasound data enables longer, noninvasive monitoring of organisms. Read More »
A characteristic feature of twisted graphene bilayers has now been seen in an analogous acoustic system. Read More »
Calculations have uncovered two previously unknown forces that act on nonspherical particles in a sound field. Read More »
A magnet-and-coil system reveals how acoustic waves reflect and refract when the host medium suddenly changes elasticity. Read More »
A small device senses sounds using a spiderweb-like design—a strategy that could lead to chip-size microphones that are less affected by thermal noise. Read More »
Producing fake sound reflections that simulate the presence or absence of an object could allow the military to hide assets underwater. Read More »
The low oscillation frequency of spin waves in chromium trichloride enables researchers to explore this antiferromagnet’s rich properties with standard laboratory equipment. Read More »
Illuminating a high-resolution lens with waves whose intensity diminishes over time can improve the image quality. Read More »
Using a “bad” acoustic mirror, physicists demonstrate a phonon beam splitter, a device that could one day be used to make phonon-based quantum logic gates. Read More »
A lightweight structure made of rubber and metal layers can provide an object with underwater acoustic stealth over a broad frequency range. Read More »
