The Internet began in the early 1970s as a "network of networks" involving several different US university and government computer systems. It quickly expanded to incorporate computer networks in other countries, including Canada.
CANADIANS ARE now committed to the reduction of greenhouse gas emissions under the Kyoto Protocol, even though Ottawa may not have a well-developed plan. But Dean Scammell does, and he's a good six years ahead of the government. In 1999, Scammell started building his 2,400-sq.
A DECADE AGO, Netscape Navigator became the world's de facto INTERNET browser almost overnight. It was a phenomenal success - that is, until Microsoft Corp.
West Nile VIRUS, a member of the flavivirus family, is related to the viruses that cause dengue and yellow fevers. The effects of infection with West Nile virus range from no symptoms to severe illness and even death.
Crops are plant species grown for human or animal consumption or for special purposes (e.g., flax, tobacco). In Canada, most major crops grown are used for food and feed.
Nuclear Energy is energy from the nucleus of an atom. In stars such as the sun, pairs of light atoms (mostly hydrogen) fuse together and release the radiation received on earth as solar energy.
Telidon, a combination of the Greek words meaning "to know at a distance," was a waypoint en route to the Internet and was an early demonstration of how technology can provide on-demand access to information.
Cancer is a term describing more than 100, possibly as many as 200, different diseases characterized by the common property of abnormal cell growth. Cancer is the second-leading cause of death in Canada and second only to accidents as a cause of death in children under 15 years of age.
Humidity is related to the amount of moisture or water vapour in the air. Although invisible, water vapour is always present in the atmosphere.
The site is important because it confirms that Centrosaurus was a herding dinosaur, and documents that the herds were larger than previously thought, numbering well into the thousands.
Heart disease, Crohn’s, even autism may be affected by the bacteria in our guts—and the fix may live there, too.
Ottawa’s unprecedented efforts to woo Verizon have sparked a fierce backlash from Canada’s carriers, and questions about what’s really best for Canadian consumers
With Keystone XL and the Northern Gateway mired in controversy, the industry turns to Plan B
Retirements and declining immigrant participation have Canada facing a critical shortage of engineers
The Canadian oil sands (or tar sands) are a large area of petroleum extraction from bitumen, located primarily along the Athabasca River with its centre of activity close to Fort McMurray in Alberta, approximately 400 km northeast of the provincial capital, Edmonton. Increased global energy demand, high petroleum dependency and geopolitical conflict in key oil producing regions has driven the exploration of unconventional oil sources since the 1970s which, paired with advances in the field of petroleum engineering, has continued to make bitumen extraction economically profitable at a time of rising oil prices. Oil sands are called “unconventional” oil because the extraction process is more difficult than extracting from liquid (“conventional”) oil reserves, causing higher costs of production and increased environmental concerns.
Hydraulic fracturing is a technique used in oil and natural gas production. It releases otherwise irrecoverable resources from certain geological formations by injecting water and additives at high pressure into the ground to create microfractures in the rock. Hydrocarbons can then flow through these fractures into a well. It has become controversial because of concerns that the technique, and well-drilling activity associated with its use, threatens groundwater, surface water, air quality, and other environmental values. Common in Alberta’s oil patch since the 1970s, the practice expanded greatly in this century, triggering gas rushes in British Columbia and Saskatchewan and resistance in several other provinces.
Montréal’s Rio Tinto Alcan Planetarium is part of the Space for Life complex, which includes Montréal’s Biodome, Insectarium and Botanical Gardens. Space for Life is the largest natural science museum complex in Canada.
The spectacular suspension bridge across the Peace River south of Fort St. John, British Columbia, was opened in the summer of 1943, replacing a ferry crossing on the Alaska Highway.
The term dioxin applies to any of 75 chlorinated derivatives of dibenzo-p-dioxin. The various types of dioxin are quite different from one another, the greatest difference being in their toxicity.
