When roots crack and worms crunch

Roots can be "listened to" while growing – and worms when burrowing. Researchers from ETH Zurich and the French National Institute for Agricultural Research present a new method for soil analysis.

Researchers couple artificial atom to acoustic resonator

Researchers from Russia and Britain have demonstrated an artificial quantum system in which a quantum bit interacts with an acoustic resonator in the quantum regime. This allows quantum optics principles to be applied in ...

Cloaking devices—it's not just 'Star Trek' anymore

Cloaking devices play a pivotal role in many sci-fi television programs. Scientists are now working to take this technology from the dramatic realm of science fiction and make it real. Amanda D. Hanford, at Pennsylvania State ...

Acoustic device makes piezoelectrics sing to a different tune

In today's "internet of things," devices connect primarily over short ranges at high speeds, an environment in which surface acoustic wave (SAW) devices have shown promise for years, resulting in the shrinking size of your ...
