These invasive jellyfish are the size of a thumbnail — and they're making a new home in B.C.

The next time you dip your toes into a lake in British Columbia, you might want to take a closer look at the water. That's because an invasive species of jellyfish believed to be native to southeast China, Craspedacusta sowerbii, is making a new home for itself in B.C.'s freshwaters. "We know they are there. We know they are potentially widespread. But before we go a step further, we need to know what they do and then we can talk about that," said Florian Lüskow, a University of British Columbia PhD candidate and researcher.

Young Innovators: New U of S app tracks causes of algae bloom

A new University of Saskatchewan smartphone app will help farmers and communities identify hotspots of nutrient contamination in freshwaters and possibly predict where algae blooms — slimy, plant-like green organisms that hinder water quality — are likely to grow. “Tracking how and where agricultural nutrients, which help crops grow, may be washed away with rainfalls and snowmelt is a major concern for both researchers and the public, and that’s where our app comes in,” said Environment and Climate Change Canada scientist Diogo Costa.
