'Nanozyme' therapy prevents harmful dental plaque build-up

A growing body of evidence points to a link between iron-deficiency anemia and severe tooth decay. Whether the connection is correlative or causative is unknown, though both conditions are associated with poor diets and are ...

Atomic-scale 'lasagna' keeps heat at bay

Researchers from Tokyo Metropolitan University have found new ways of controlling how heat flows through thin materials by stacking atomically thin layers of atoms into van der Waals heterostructures. By comparing different ...

A new way to remove troublesome ions from water

Converting seawater into fresh water is important in water-scarce countries. For that process, certain charged particles—known as ions—have to be removed from the water. However, some ions are difficult to remove from ...

Canada's nitrogen footprint shows great regional variation

Reactive nitrogen emissions contribute to greenhouse gases, as well as air and water pollution. For the first time, researchers from McGill University have calculated Canada's nitrogen footprint (akin to a carbon footprint) ...

A breakthrough in catalysts: Smaller than nanoscale

For two decades, manipulating materials at the nanoscale to develop efficient catalysts for various applications, including water treatment, has been the gold standard in the field. But a new study goes even smaller—down ...
