Chemists build a better rapid antigen test

BY: Sharon Oosthoek

As most of us know by now, the tradeoff of the ease and speed of rapid antigen tests is low sensitivity. But now a team of chemists from York University has figured out how to reduce false negatives without making the test overly difficult for home use.

Carence en iode : un risque plus élevé au Québec qu’en Ontario

BY: Marine Corniou

Inodore et sans saveur, l’iode est un élément discret qui n’a aucun intérêt culinaire. Il est pourtant ajouté au sel de table, sous forme d’iodure de potassium, dans pratiquement tous les pays du monde. Et pour cause …

Mosquito brains zero in on two human odors

BY: Sharon Oosthoek

Some mosquitoes feed almost exclusively on humans. The chemical odors they use to differentiate us from dogs, rats, pigs or birds were a mystery. Until now.

Science that gets under our skin

BY: Lesley Evans Ogden

Scientists are on a quest to create materials that mimic the sensory abilities of human skin for uses like the surfaces of robots and prosthetics. This skin-like salt-infused gel is a step towards that goal.
