In 1997, a forest fire in Indonesia ignited an area of peatlands that smouldered for months. By the time it was over, the fire had released greenhouse gases equal to 20 to 40 percent of the total worldwide emissions that year from fossil fuels. But that could be a drop in the bucket compared to future emissions from peat fires. Indonesian peatlands are dwarfed by Canada's. The total area of all peatland in Canada is estimated to be about twice the size of Saskatchewan.

The Star Factory: Observing Arp 220
The galaxy Arp 220 is home to several giant star clusters—about 10 million solar masses—that are twice as massive as any comparable star cluster in the Milky Way Galaxy. McMaster University's Christine Wilson is captivated by this turbulent galaxy that provides such a target-rich environment for watching stars form.
Smart Grids Could Outsmart Criminals
Your smart phone uses broadband to connect you to the world. But when charging it, you're relying on an electrical system that was designed and built in the era of the rotary phone. Because these systems are becoming outdated, too much electricity is slipping between our fingers, even as politicians highlight the need for "energy security". Plus, generating power to keep up with increasing demand is getting harder because communities oppose new plants in their backyard.
Repelling the Knapweed Invasion
The problem of invasive species may seem remote from most people's lives. But in some parts of the United Kingdom, an invasive plant creates a problem that hits home, literally. That's because the presence of invasive knotweed on a property prevents potential buyers from obtaining a mortgage. This destructive plant from Asia, which can tear down walls and rip up roads, is also putting down roots in many parts of Canada.

From 'Science from Above' to 'Science in the Community'
Most research initiatives aim to discover more knowledge. The International Polar Year (IPY) went even further; it created more discoverers. That is what Canadian Arctic researcher David Hik will tell this week's meeting of the American Association for the Advancement of Science (AAAS) in Vancouver. "For the first time in the 130-year history of international polar years, people living in polar regions were not just objects of study — they led studies," said Hik.
