Biodiversity in shallow Arctic lakes

Shallow Arctic lakes that remain unfrozen throughout the year contain more diverse biofilms than lakes that freeze up for a period of time, a new study has found. Researchers analyzed the genetic material of biofilm—which is a group of microorganisms that stick to one another, forming a so-called “microbial mat” on the surface of a lake—in […]

Underground fungi network helps forests spread farther

Forests that are facing the dangers of disappearing from the effects of climate change might have an unlikely ally: ancient underground fungi. A recently published paper puts forward a theory called the “paleosymbiosis hypothesis,” which states that tree roots can activate an underground fungal network that has laid dormant for millennia. These fungi could helping […]

A drop of oil slows down seabird flight

Even the smallest amount of oil can disrupt the delicate mechanisms behind the flight of seabirds, a new study suggests. Crude oil on the feathers of waterfowl significantly increase the amount of energy the birds have to spend in order to fly, making the birds’ wings and bodies less aerodynamic. Researchers trained wild western sandpipers […]

Neonic pesticides increase mortality rates among worker and queen honey bees

First-ever study using realistic field doses of neonicotinoid pesticides has confirmed their deadly effects on honey bee populations. Researchers have quantified the length and magnitude of pesticide exposure in Canada’s cornfields, and mimicked the exposure in a lab setting. They found that the lifespans of worker and queen honey bees are cut by 23% after […]

How alternative medicine practitioners may be spreading the anti-vaccination sentiment

Tighter regulations of complementary and alternative medicine (CAM) providers are necessary to stop the spread of misinformation about vaccines, according to a new paper. Researchers have examined 330 websites of CAM providers in Alberta and BC, to evaluate how these practitioners may be contributing to the anti-vaccination sentiment among their patients. Their findings showed that […]

Fundamental research is failing in Canada: survey

The number of scientists investigating basic-science questions in Canada has dropped by nearly 20%, a new survey reports. Reasons for the drop include decreased funding and institutional preference for applied research over fundamental research. Over 1,300 Canadian researchers took part in an online survey that asked them to share their views on the state of […]

Improving the cellular backpack

Medicine can be delivered to specific parts of the body by fitting it inside a “backpack” and attaching it to white blood cells. This targeted drug delivery means other tissues of the body aren’t affected, and side effects are limited.  Original research presented at a meeting of the American Chemical Society on March 17, 2015.

The Brain Prize – Congratulations Dr. Collingridge

Dr. Graham Collingridge, Chair of the Department of Physiology, University of Toronto, has been awarded The Brain Prize, widely known as the “Nobel of neuroscience”,  for his research on the cellular mechanisms of learning and memory. The million euro prize is awarded by the Grete Lundbeck European Brain Research Foundation in Denmark. Dr. Collingridge shares […]

The role of science in Canadian policy

The Science Integrity Project, which aims to make evidence-based decision-making a high priority for government at all levels, has released four principles for  improving policy decisions using the best available evidence. The principles were developed through the collective wisdom of 75 leaders — in science, indigenous knowledge, public policy, civil society, and governance. The project […]

Permafrost is soil that remains below the freezing point of water from one year to the next, resulting in permanently frozen water particles in the soil. (Image created by the PAGE21 project)

First global permafrost database launch

The first online database on global permafrost is freely available to the public, serving as an early warning system for decision-makers around the world, as well as providing standardized permafrost measurements for the first time. The database, from the Global Terrestrial Network for Permafrost, has brought together scientists from 25 countries and who have drilled over 1000 […]
