Biochemistry, encompasses the study of the chemical nature of living material and of the chemical transformations that occur within it.

About a third of the world's estimated 400 000 species of higher or vascular plants have probably been used for medicinal purposes by indigenous societies, generally in a raw or minimally processed form.

Pointe-du-Buisson is a small point of land (21 ha) extending into the waters of Lake St Louis (a widening of the St-Lawrence River) at the convergence of the Ottawa River.

In 1950, one of Canada’s greatest medical innovations was developed at the University of Toronto’s Banting Institute. Cardiac surgeon, Dr. Wilfred Bigelow and research fellow, Dr. John Carter Callaghan were trying to understand how hypothermia (see Cold-Weather Injuries) could slow the beating of an animal’s heart before surgery. They were also looking for a way to stimulate the heart when it faltered as it cooled. This largely unknown area of research could have tremendous applications for humans. The doctors partnered with Dr. John A. Hopps from the National Research Council of Canada, who created a portable artificial external pacemaker. It was designed to send electric pulses to the heart, which caused the heart to contract and pump blood to the body. The device was successfully tested on a dog in 1950. This landmark discovery paved the way for the use of implantable pacemakers in humans.

Media convergence refers to the merging of previously distinct media technologies and platforms through digitization and computer networking. This is also known as technological convergence. Media convergence is also a business strategy whereby communications companies integrate their ownership of different media properties. This is also called media consolidation, media concentration or economic convergence. (See also Media Ownership.)

There have been many tragic events in Canada’s aviation history. Some of these have involved Canadian aircraft, commercial as well as non-commercial. In other cases, many Canadians have died in the crash of a non-Canadian aircraft. Crashes that occurred over Canadian soil, or search and rescue efforts in which Canadians have played a large part, are also part of this history.

One of the easiest ways to understand bitumen is to compare it to its cousin, conventional crude oil. Whereas conventional crude oil flows freely, bitumen does not. At room temperature it looks like cold molasses, and must be either heated or diluted before it flows.

The petrochemical industry, which produces chemicals using OIL AND NATURAL GAS as major raw materials, occupies an important position in Canada's MANUFACTURING and consuming sectors. Oil and natural gas are composed primarily of hydrocarbons. Most petrochemicals contain hydrogen or carbon or both.

Some 2000 Canadians between the ages of one and 19 are killed each year because of injury, and over 85 000 are hospitalized. With the control of infectious diseases, injury has become the leading cause of death and disability in Canadian children and youth.

If life expectancy is any indication of health, Canadian women are, on average, much healthier than they were 70 years ago. The life expectancy of female babies born in 1921 was 61 while female babies born today are expected to live to age 82.

GM plants were first marketed in the 1990s. The first commercialized GM crop was a TOMATO called Flavr Savr (resistant to rotting), marketed in 1994 by a US-based company, Calgene. Since then, many GM crops have been commercialized.

Tipis are cone-shaped dwellings that many Plains Indigenous peoples used to live in until the mid-1800s. Today, tipis retain cultural significance and are sometimes constructed for special functions. (See also Architectural History of Indigenous Peoples in Canada.)

However, the launch may be threatened by American interests.

Canada helped develop the world’s first nuclear reactors and nuclear arms. During the Second World War, Canada participated in British research to create an atomic weapon. In 1943, the British nuclear weapons program merged with its American equivalent, the Manhattan Project. Canada’s main contribution was the Montreal Laboratory, which later became the Chalk River Laboratory. (See Nuclear Research Establishments). This Allied war effort produced the atomic bombs dropped on the Japanese cities of Hiroshima and Nagasaki in 1945. It also led to the development of Canada’s nuclear energy industry.

Few inventions have left as profound a mark on the world as the automobile. The first automobiles built in Canada were regarded as novelties, but the Canadian automotive industry eventually expanded to become one of the country’s significant manufacturing and exporting sectors. Assembly-line production helped reduce the cost of automobiles and made it possible for more individuals to purchase them. The rise of the automobile has impacted travel and it has necessitated research and regulations into pollution, safety standards and sustainability (see Transportation; Traffic Law in Canada).
