An analysis of a 30,000-year-old fossil vulture from Central Italy has revealed for the first time that volcanic rock can ...

First, a special type of microscope called a two-photon microscope is used, which can look deep into live tissues with minimal damage. To improve how steady the tissue remains during imaging, they ...

Non-invasive microscopic techniques such as optical coherence microscopy and two-photon microscopy are commonly used for in vivo imaging of living tissues. When light passes through turbid materials ...
