Chicken, chocolate and celiac disease

What do poultry, chocolate, bananas and cruciferous vegetables such as broccoli, cabbage and cauliflower have in common? They all contain an essential amino acid called tryptophan, which launches a biochemical chain reaction in the body that controls intestinal inflammation and keeps the gut barrier healthy. In people with celiac disease though, that reaction is impaired,...

How the virus’s chemical signature gives advance warning of the rise and fall of community transmission. As the pandemic’s second wave tightens its grip across the country, researchers, municipalities, and public health agencies are experimenting with a COVID-19 early warning system that tests wastewater for the virus’s unique chemical signature. Swab tests for the coronavirus are expensive and we aren’t capturing enough data for a true picture of how many people are infected, say epidemiologists.

Medical masks that kill the COVID-19 virus

CHEMISTRY FOR HEALTH

Researchers put anti-microbial mask coatings to the test. Triiodide, salt, and graphene-nano silver take their turn on the lab bench. Face masks with COVID-fighting coatings may be the next frontier in PPE. At least one such mask is available commercially in Canada – using a triiodide coating – and researchers are investigating the virus-busting powers...
