Every Canadian has a stake in helping to shape the country’s energy systems. But how do we make sense of the ever-increasing and complex information about issues such as pipeline safety, environmental impacts and economic benefits?

Nationwide, counties with the poorest quality across five domains – air, water, land, the built environment and sociodemographic – had the highest incidence of cancer, according to a new study published in the journal Cancer.

The digging, stirring and overturning of soil by conventional ploughing in tillage farming is severely damaging earthworm populations around the world, say scientists.

Our ever-changing sun continuously shoots solar material into space. The grandest such events are massive clouds that erupt from the sun, called coronal mass ejections, or CMEs. These solar storms often come first with some kind of warning — the bright flash of a flare, a burst of heat or a flurry of solar energetic particles. But another kind of storm has puzzled scientists for its lack of typical warning signs: They seem to come from nowhere, and scientists call them stealth CMEs.

In a new study researchers have found that although warmer weather should benefit badger populations, the predicted human population increase in the Scottish highlands is likely to disturb badgers and counteract that effect. These results emphasise the importance of interactive effects and context-dependent responses when planning conservation management under human-induced rapid environmental change.
