The more at risk a marine fish is in Canada, the less likely it is to be listed on the Species At Risk Act according to new research. According to Susanna Fuller, co-author and Marine Program Coordinator at the Ecology Action Centre in Halifax, “less than 20% of at-risk marine fishes in Canada have been […]

A new “silent spring”
An editorial is calling the dumping of plastic waste into the ocean a new “silent spring”. “Silent spring” was a book written in the 1960s outlining the harmful effects of the overuse of pesticides on the environment. It was instrumental in raising public awareness of the potential dangers of pesticides. The authors of the paper […]
Phytoplankton produces its own vitamins
A type of phytoplankton found all over the world appears to be able to survive without external supplies of vitamin B1, leading to a re-thinking of how the vitamin controls growth and carbon uptake in the global oceans. The availability of nutrients and vitamins in the ocean is a key limiting factor controlling blooms of phytoplankton, […]
Digesting dinner keeps leatherback turtles warm
Scientists have determined that metabolic heat produced from digesting prey is a key component of what keeps leatherback turtles warm in the cold waters off Canada’s Atlantic coast. Researchers attached temperature monitors to seven leatherback turtles off the coast of Cape Breton and discovered that they cool down during the day (most likely due to […]
Breast surgery trends differ across Canada
Breast cancer patients from Newfoundland and Labrador were more likely to have mastectomies than those in other provinces, a new study shows. The research examined 57 840 Canadian women from 2007 to 2009 who underwent breast cancer surgery; many of those patients could undergo either mastectomy or breast-conserving surgery, called lumpectomy, which is usually followed […]
Rare seahorse spotted off Nova Scotia
Two divers recently spotted a lined seahorse (Hippocampus erectus) – rarely seen in Canada – off St. Margaret’s Bay, Nova Scotia. They uploaded the photo to iSeahorse, a smartphone app developed by an international team of seahorse scientists, including UBC marine biologist Amanda Vincent. The ‘citizen science’ initiative is critical due to the fact that […]
New nanoparticles provide superior pollution prevention
Removing toxic carbon monoxide (CO) from car exhaust and other pollution sources could soon be cheaper and more efficient, thanks to a new type of nanoparticle catalyst. Catalytic converters that turn CO into benign CO2 rely on expensive metals like platinum to speed up the chemical reaction. The new nanoparticles combine platinum with cheaper iron […]
