Psychedelic Research in 1950s Saskatchewan
In the 1950s, Saskatchewan was home to some of the most important psychedelic research in the world. Saskatchewan-based psychiatrist Humphry Osmond coined the word psychedelic in 1957. In the mental health field, therapies based on guided LSD and mescaline trips offered an alternative to long-stay care in asylums. They gave clinicians a deeper understanding of psychotic disorders and an effective tool for mental health and addictions research. Treating patients with a single dose of psychedelic was seen as an attractive, cost-effective approach. It fit with the goals of a new, publicly funded health-care system aimed at restoring health and autonomy to patients who had long been confined to asylums.

Sasquatch is said to be a large, ape-like creature that lives primarily in the forests stretching from the West Coast of British Columbia to Northern California, and to a lesser extent throughout North America. Sasquatch is a cryptid — a creature whose existence is suggested, but has not yet been confirmed by the scientific community. Like the Yeti of Asia or the Abominable Snowman of the Himalayas, Sasquatch is rooted in Indigenous legend and is commonly researched by cryptozoologists and enthusiasts. Some believe Sasquatch is a nearly extinct species of hominid that survives in isolation, while others consider the creature to be the product of folklore and a hoax.

Ice Age, the Pleistocene epoch of geologic time, during which periodic, extensive glacial activity occurred in many parts of the world.
Asthma is a chronic inflammatory disease of the lungs that is marked by recurring episodes of airway obstruction. It is one of the most prevalent chronic conditions affecting Canadians. Asthma often begins in childhood, but initial onset can occur at any age.
Multiple Sclerosis (MS) is an autoimmune disease that impacts the body’s central nervous system. As of September 2020 an estimated 2.8 million people are living with MS worldwide.

Soil science is the science that deals with soils as a natural resource. Studies focus on soil formation, classification and mapping, and the physical, chemical and biological properties and fertility of soils as such and in relation to their management for crop production.
Hydroelectricity in Canada
Hydroelectricity is energy produced from flowing water. The amount of energy produced depends on volume and speed: the more water moving at a fast rate, the more energy produced. For this reason, many hydroelectric stations are built near waterfalls. To produce energy, water is directed toward turbines — sometimes with the help of a dam — causing them to spin. In turn, the turbines make electrical generators spin and electricity is produced. It is a renewable, comparatively nonpolluting energy source and Canada’s largest source of electric-power generation.
Sabotage of Top Web Sites
How do you find out if your house is secure? One answer: try to bust in and see how hard it is. The cyberspace equivalent is what a northern Virginia company called Global Integrity was doing last week - paying half a dozen young computer whizzes to break into Web sites run by their clients.
