Sub-wavelength lateral detection of tissue-approximating masses using an ultrasonic metamaterial lens
Nature Communications, Published online: 24 November 2020; doi:10.1038/s41467-020-19591-2 Traditional methods for ultrasound detection in biomedical application suffer from limited lateral resolution. Here, the authors show that a phononic metamaterial lens can be used for spatial characterisation of subwavelength objects, even beyond the Fresnel zone of the emitting transducer.

It is often assumed that domestic dogs are the primary source of CDV, but a new study found that other local wildlife was the primary source of CDV transmission to tigers instead.
