The ability to quantify optical properties (i.e., absorption and scattering) of strongly turbid media has major impacts on the characterization of biological tissues, fluid fields, and many others.

A sound too high for you to hear may one day help keep hedgehogs off the road. That possibility comes from a new study in Biology Letters reporting that European hedgehogs can hear ultrasound, with ...
