Potassium sulfite is a chemical compound. Its chemical formula is KSO. It contains potassium and sulfite ions.
It is a white crystalline solid. It is a reducing agent. It can react with oxidizing agents to make potassium sulfate.
It is made by reacting sulfur dioxide with potassium hydroxide.
It is used to preserve food. Sulfites can cause allergies in some people, though.

Hurricane Gloria
Hurricane Gloria was an Atlantic tropical cyclone in September 1985. The storm was the first major storm to affect Long Island and New York directly since Hurricane Donna 25 years before.
The storm started as a tropical depression on September 16; it became Tropical Storm Gloria on September 17.
On September 18, it weakened back to a tropical depression. Two days later, it became a tropical storm again.
After being a weak tropical cyclone for several days, on September 22, Gloria became a hurricane. It quickly became stronger on September 24; the next day, its winds peaked at 145 mph. A 2008 reanalysis later found the winds had been even stronger.
On September 27, the hurricane struck eastern North Carolina as a Category 2 storm. It then moved up the East Coast of the United States. Later that day, the storm struck western Long Island, with winds of 85 mph. One hour after striking Long Island, it hit near Westport, Connecticut.
Gloria moved northeast through Atlantic Canada.
Damage from the storm was $900 million.
The death toll from the storm was fourteen.
The name "Gloria" was later retired and replaced with "Grace".

Immune system
The immune system is the set of tissues which work together to resist infections. The immune mechanisms help an organism identify a pathogen, and neutralize its threat.
The immune system can detect and identify many different kinds of disease agents. Examples are viruses, bacteria and parasites. The immune system can detect a difference between the body's own healthy cells or tissues, and 'foreign' cells. Detecting an unhealthy intruder is complicated, because intruders can evolve and adapt so that the immune system will no longer detect them.
Once a foreign cell or protein is detected, the immune system creates antibodies to fight the intruders, and sends special cells ('phagocytes') to eat them up.
Even simple unicellular organisms such as bacteria possess enzyme systems that protect against viral infections. Other basic immune mechanisms appeared in ancient life forms and remain in their modern descendants, such as plants and insects. These mechanisms include antimicrobial peptides (called defensins), phagocytosis, and the complement system. These make up the innate immune system, which defends the host from infections in a non-specific way. The simplest innate system is the cell wall or barrier on the outside to stop intruders getting in. For example, skin stops most outside bacteria getting in.
Human Innate Immune System Response
Our innate immune system responds very fast to anything foreign that enters our body. When something gets past our skin, like through a cut, our immune cells work to find the intruder and to alert each other of the foreign object. Small immune cells bring other cells from all over the body to the site where the foreign object was found. Other immune cells can send out messengers to cells nearby to have them help attack the foreign object. This process can make our skin look red and feel hot. A certain type of cell called a phagocyte eats anything foreign or dangerous that enters your body. This response is called non-specific because it responds the same way to anything foreign that enters your body from germs to a piece of dust.
Vertebrates, including humans, have much more sophisticated defense mechanisms. The innate immune system is found in all metazoa, but the adaptive immune system is only found in vertebrates.
The adaptive immune response gives the vertebrate immune system the ability to "recognize and remember specific pathogens". The system mounts stronger attacks each time the pathogen is encountered. It is adaptive, because the body's immune system prepares itself for future challenges.
The typical vertebrate immune system consists of many types of proteins, cells, organs, and tissues that interact in a complex and ever-changing network. This acquired immunity creates a kind of "immunological memory".
The process of acquired immunity is the basis of vaccination. Primary response can take 2 days to 2 weeks to develop. After the body gains immunity towards a certain pathogen, if infection by that pathogen occurs again, the immune response is called the "secondary response".
In some organisms, the immune system has its own problems within itself, called "disorders". These result in other diseases, including autoimmune diseases, inflammatory diseases and possibly even cancer. Immunodeficiency diseases occur when the immune system is less active than normal. Immunodeficiency can either be the result of a genetic (inherited) disease, or an infection, such as the acquired immune deficiency syndrome (AIDS), that is caused by the retrovirus HIV, or other causes.
In contrast, autoimmune diseases result from an immune system that attacks normal tissues as if they were foreign organisms. Common autoimmune diseases include Hashimoto's thyroiditis, rheumatoid arthritis, Type 1 diabetes, and Lupus erythematosus.
Immunology is the study of all aspects of the immune system. It is very important to health and diseases.
Immunology is scientific part of medicine that studies the causes of immunity to disease. For many centuries people have noticed that those who recover from some infectious diseases do not get that illness a second time.
