CSU engineers introduce a better way to perform mosquito-tracking for disease applications

West Nile, Zika, dengue and malaria are all diseases spread by bites from infected mosquitoes. To track the threat of such diseases over large populations, scientists need to know where the mosquitoes are, where they've been, and where they might go.

Powerful imaging tool creates 3D atlas of the spectrum of tuberculous and COVID-19 lung lesions

Gross anatomy reveals three-dimensional shapes of pathology at a large scale. Histology, in contrast, reveals the microscopic anatomy of biological structures. But that magnification comes at a cost -; histology shows only two-dimensional shapes because it studies small, flat slices of stained tissue.
