Natural Science

Fascinating to scientists and zoo visitors alike, gorillas are the gentle giants of the animal world. Year by year, gorillas in the wild are losing habitat to advancing human settlement, prompting conservation groups and UN agencies to name 2009 the Year of the Gorilla. From a 1963 interview with a hunter who captures gorillas for zoos to a radio snapshot of wild gorillas in 2009, the CBC Digital Archives looks at these hairy, human-like creatures.

Technology

If the telephone wasn't born in Canada, it was certainly conceived here. In 1874, in Brantford, Ont., inventor Alexander Graham Bell first described the scientific principle that would convey the human voice over wires. By the Second World War, Canadians led the world in talking by telephone. Later they reached out to each other and around the globe with long distance calling, transatlantic connections and predictions for the future.

The Unexplained

It can border on the outrageous, the credible and even the entrepreneurial. For centuries people claimed to have boarded UFOs, encountered aliens and even sipped on Crop Circle Beer. Skeptics may dismiss believers as nerds and nutters but there's no doubting the increasing popularity of the paranormal in the mainstream. Canada has one of the highest rates of UFO sightings per capita and, for many Canadians, life beyond earth is a definite reality.

Natural Science

A dry forest, some hot weather, and high winds: all it takes to set off a raging fire in these conditions is a lightning strike or a careless camper. Every summer, forest fires threaten people, property and valuable timber in Canada. But we've learned to combat these fires with a combination of scientific research, new inventions and old-fashioned courage. From lookout towers to water bombers to remote sensing that predicts fire, Canada has long been a world leader in the technology of fighting forest fires.

Measurement

Depending on your perspective, it was either a sensible scientific shift, an annoying unnecessary change or a sinister communist plot. Canada's decision to go metric in 1970 definitely sparked some passionate debates. It even drove some Canadians to civil disobedience. CBC Archives explores the history of Canada's gradual and sometimes shaky transition to the metric system ? a transition that, to this day, has yet to be fully completed.

Biotechnology

Since the introduction of the first genetically modified food, the "Flavr Savr" tomato in 1994, "GM" products can now be found in thousands of foods, from bagels to butter tarts to soy milk. While the biotech industry points to the safety and benefits of genetic modifications, environmentalists are quick to denounce it as potentially harmful "frankenfood." And that has left the consumer caught in the middle of this emotionally charged debate.

Engineering

They could zoom through underground tunnels at high speeds, transporting passengers to their destinations comfortably and efficiently. Canada's two new subways were considered marvellous feats of modern engineering in the 1950s and '60s. As the decades passed, Toronto's subway and Montreal's metro became more than just technological marvels ? they were also places for people to meet, musicians to perform and artists to display their work.

Energy Production

From rushing rivers deep in Canada's wilderness comes the electricity that keeps our cities humming. As a renewable, emissions-free source of energy, hydroelectricity is "green," but flooding from hydroelectric dams has sometimes devastated traditional aboriginal livelihoods. Ranging from a single tidal turbine to Niagara Falls to a dam carved from a mountain, Canada's hydro projects provide 60 per cent of this country's power.
