A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams have now found a mechanism by which tissues can be ...

Tissue optical clearing is a fundamental technique that enhances light penetration deep into biological samples by reducing light scattering through refractive index homogenization. This process ...

As a researcher, I still remember the discomfort I felt every time I had to sacrifice laboratory animals for an experiment. For decades, animals like mice, rats and pigs have been essential tools in ...

A new tissue expansion method enables scientists to use mass spectrometry imaging to simultaneously detect hundreds of molecules at the single cell level in their native locations. For biologists, ...

Persistent organic pollutants (POPs) begin to accumulate in the tissues of mammals already during the fetal stage, according to new research from the University of Oulu, Finland. The animal-model ...

An analysis of a 30,000-year-old fossil vulture from Central Italy has revealed for the first time that volcanic rock can preserve microscopic details in feathers - the first ever record of such a ...
