A new University of Waterloo study shows that current Hepatitis B vaccination, screening, and treatment strategies in Ontario will leave the province well short of its goal to reduce preventable infections that afflict 1,000 Ontarians annually.

Fluorescence microscopy shows how living cells form vesicles to transport cargo like growth factors

Cells have a clever way to transport cargos like growth factors across the cell membrane and into the cell. It is called clathrin-mediated endocytosis. Molecules of the protein clathrin gather on the inside of the cell membrane, and they deform the membrane to make what looks like a pit as seen from the outside.

Installation of deep-water pipeline gives immediate boost to sea-floor animals

An underwater survey west of Africa, off the Angolan coast, found that both the abundance and types of animals on the deep-sea floor increased significantly in response to the installation of a pipeline. Published in Frontiers in Marine Science, the study also revealed a large increase in the amount of litter on the seafloor, which was trapped against the pipeline.
