Acoustic wave behaviour is affected by material parameters such as mass density and bulk modulus of the media where the wave propagates. Metamaterials provide a new strategy to design unprecedented ...

MIT engineers have devised a new, noninvasive way to measure the stiffness of living cells using acoustic waves. Their technique allows them to monitor single cells over several generations and ...

Last year, there was some excitement from Star Trek fans when scientists announced that they now knew how to structure a material that would cause light to flow around it. This was quickly followed by ...
