Children and youth with learning disabilities typically have average to above average intelligence but also have problems perceiving (making sense of) or using information that results in a pattern of uneven abilities and observable weaknesses in reading, writing, speaking, listening, problem solving, mathematics, and social skills.

Spectroscopy is the field of study that examines, measures and interprets the electromagnetic spectra produced when radiant energy is emitted or absorbed by a substance. Spectroscopic methods are important in performing chemical analyses of substances and are used in astronomical studies.

Spodumene is a lithium aluminum silicate (8.0% Li2O, 27.4% Al2O3, 64.6%SiO2) and is the world's most common commercially mined lithium ore mineral. Petalite, lepidolite and amblygonite are also mined in different parts of the world.

Statistics is the science concerned with the collection and analysis of numerical information to answer questions wisely. The term also refers to the numerical information that has been collected. Statistics has many applications in Canada, from government censuses and surveys, to decision making in industry, to medical research and technological innovation.

Statistics Canada is the nation’s central statistical agency. It was established in 1918 as the Dominion Bureau of Statistics and adopted its present name in 1971. Under the Statistics Act of that year, it has the responsibility to “collect, compile, analyse, abstract and publish statistical information relating to the commercial, industrial, financial, social, economic and general activities and condition of the people.” The agency works with government departments to develop integrated social and economic statistics for Canada and the provinces and territories. In addition, Statistics Canada is a scientific research organization that develops methodologies and techniques related to statistics and survey design.

Women now make up slightly more than half of all people living in Canada. In fact, in 1991, the last census year, 50.4 per cent of the total population was female, compared with 50.2 per cent in 1981 and 48.4 per cent in 1921.This article was originally published in Maclean's Magazine on August 21, 1995

Stem cells are the body's "building blocks"; they are the cells from which all tissues and organs are derived. They have the ability to divide while still maintaining their identity, yet they can also develop into specialized cells in response to certain stimuli. They can be found in a wide range of tissues in mammals at different stages of development and in adult organisms in tissues like nerve, muscle and skin. Stem cells from adults have a more restricted range of development. In order to develop new treatments for specific conditions scientists must understand more about how cell differentiation is directed by biological signals. New methods need to be found to grow large numbers of desired cells and more scientific experimentation involving different types of stem cells is vital. It will take many years for research projects to provide sufficient knowledge about stem cells to make new treatments possible (see Medical Research).

The practice of sterilization arose out of the eugenics movement and has a long, often hidden history in Canada. Sterilization legislation in Alberta (1928–72) and British Columbia (1933–73) attempted to limit the reproduction of “unfit” persons, and increasingly targeted Indigenous women. Coerced sterilization of Indigenous women took place both within and outside existing legislation, and in federally operated Indian hospitals. The practice has continued into the 21st century. Approximately 100 Indigenous women have alleged that they were pressured to consent to sterilization between the 1970s and 2018, often while in the vulnerable state of pregnancy or childbirth.

Stress was originally viewed as an overpowering external force acting upon individuals or objects. The mechanical engineer still uses the word in this sense, but human biologists have been less consistent in their terminology.
