Science World (Vancouver)
Science World is a science centre run by a not-for-profit organization called ASTC Science World Society in Vancouver, British Columbia, Canada. It is located at the end of False Creek and features many permanent interactive exhibits and displays, as well as areas with varying topics throughout the years. Prior to the building being handed over to Science World by the city government in 1987, the building was built as Expo Centre for the Expo 86 world's fair. Following the end of Expo 86, the building was re-purposed as a science centre. The science centre opened on May 6, 1989, as Science World. From 2005 to 2020, the museum was branded as Science World at Telus World of Science, before it reverted to its original name. History In 1977, Barbara Brink ran mobile hands-on exhibits known as the ''Extended I'' around British Columbia's Lower Mainland. Later, the temporary ''Arts, Sciences & Technology Centre'' opened in downtown Vancouver on January 15, 1982, attracting over 600, ...

Telus Spark
TELUS Spark Science Centre is a science museum with interactive exhibits, multimedia presentations and educational demonstrations in Calgary, Alberta, Canada. There are more than 430,000 visitors annually, including over 82,000 students. The science museum was established in 1987 as the Calgary Science Centre.

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Antimicrobial
An antimicrobial is an agent that kills microorganisms or stops their growth. Antimicrobial medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria, and antifungals are used against fungi. They can also be classified according to their function. Agents that kill microbes are microbicides, while those that merely inhibit their growth are called bacteriostatic agents. The use of antimicrobial medicines to treat infection is known as antimicrobial chemotherapy, while the use of antimicrobial medicines to prevent infection is known as antimicrobial prophylaxis. The main classes of antimicrobial agents are disinfectants (non-selective agents, such as bleach), which kill a wide range of microbes on non-living surfaces to prevent the spread of illness, antiseptics (which are applied to living tissue and help reduce infection during surgery), and antibiotics (which destroy microorganisms within the body).

Pfizer–BioNTech COVID-19 Vaccine
The Pfizer–BioNTech COVID-19 vaccine ( INN: tozinameran), sold under the brand name Comirnaty, is an mRNA-based COVID-19 vaccine developed by the German biotechnology company BioNTech. For its development, BioNTech collaborated with American company Pfizer to carry out clinical trials, logistics, and manufacturing. It is authorized for use in people aged five years and older in some jurisdictions, twelve years and older in some jurisdictions, and for people sixteen years and older in other jurisdictions, to provide protection against COVID-19, caused by infection with the SARS-CoV-2 virus. The vaccine is given by intramuscular injection. It is composed of nucleoside-modified mRNA (modRNA) encoding a mutated form of the full-length spike protein of SARS-CoV-2, which is encapsulated in lipid nanoparticles. Initial advice indicated that vaccination required two doses given 21 days apart, but the interval was later extended to up to 42 days in the US, and up to four months i ...

Lipid Nanoparticle
lipid nanoparticles (LNPs), are nanoparticles composed of lipids. They are a novel pharmaceutical drug delivery system (and part of nanoparticle drug delivery), and a novel pharmaceutical formulation. LNPs as a drug delivery vehicle were first approved in 2018 for the siRNA drug Onpattro. LNPs became more widely known in late 2020, as some COVID-19 vaccines that use RNA vaccine technology coat the fragile mRNA strands with PEGylated lipid nanoparticles as their delivery vehicle (including both the Moderna and the Pfizer–BioNTech COVID-19 vaccines). Characteristics A lipid nanoparticle is typically spherical with an average diameter between 10 and 1000 nanometers. Solid lipid nanoparticles possess a solid lipid core matrix that can solubilize lipophilic molecules. The lipid core is stabilized by surfactants (emulsifiers). The emulsifier used depends on administration routes and is more limited for parenteral administrations. The term lipid is used here in a broader ...

Acuitas Therapeutics
Acuitas Therapeutics Inc. is a Canadian biotechnology company based in Vancouver, British Columbia. The company was established in February 2009 to specialize in the development of delivery systems for nucleic acid therapeutics based on lipid nanoparticle (LNP) technology, a key component of the mRNA vaccines deployed for COVID-19. History Inex Pharmaceuticals Dr. Pieter Cullis was among several scientists experimenting with liposomes in the early 1980s, fascinated by their properties in many aspects of human biology. Cullis discovered he could load cancer drugs into liposomes, inspiring him and several colleagues at the University of British Columbia to form Inex Pharmaceuticals in 1992. One of Inex's co-founders was Thomas Madden, who had then recently emigrated to Canada from the United Kingdom to complete post-doctoral studies in biochemistry. Tekmira Pharmaceuticals To improve prospects of successfully advancing gene therapy techniques, Cullis developed and patente ...

Bonnie Henry
Bonnie J. Fraser Henry (born ) is a Canadian physician who is the Provincial Health Officer for British Columbia, the first woman in this position. Henry is also a clinical associate professor at the University of British Columbia. She was a family doctor and is a specialist in public health and preventive medicine (also known as community medicine). Her early handling of the COVID-19 pandemic in British Columbia earned praise from the ''New York Times'' in June 2020. In August, September, and October 2020, Henry was criticized for not mandating public mask usage and BC's back-to-school plans. In November and December concerns were raised regarding the lack of transparency around COVID-19 data. In December 2021 she was criticized for previous claims that COVID mostly spreads by droplets instead of aerosols. A book written by Bonnie Henry and Lynn Henry was released in February 2021 called ''Be Kind, Be Calm, Be Safe''. It describes the four early weeks of the COVID-19 pandemic. ...
