Today's Food Holiday
  • National Jelly Bean Day: More
    From Wikipedia: 'Jelly beans are small bean-shaped sugar candies with soft candy shells and thick gel interiors. The confection comes in a wide variety of colors and flavors, and is primarily made of sugar.'

    'It is generally thought that jelly beans first surfaced in 1861, when Boston confectioner William Schrafft urged people to send his jelly beans to soldiers during the American Civil War. It was not until July 5, 1905, that jelly beans were mentioned in the Chicago Daily News. The advertisement publicised bulk jelly beans sold by volume for nine cents per pound, according to the book The Century in Food: America's Fads and Favorites. Today, most historians contend that jellybeans were first linked with celebrations of Easter in the United States sometime in the 1930s for their egg-like shape. In politics, jelly beans earned fame as Ronald Reagan claimed them as his favorite treat.

    National jelly bean day is on April 22.'

    'The basic ingredients of jelly beans include sugar, corn syrup, and pectin or starch. Relatively minor amounts of the emulsifying agent lecithin, anti-foaming agents, an edible wax such as beeswax, salt, and confectioner's glaze are also included. The ingredients that give each bean its character are also relatively small in proportion and may vary depending on the flavor'.
Other celebrations/observances today:
  • Girl Scout Leaders Day: More
  • Earth Day/International Mother Earth Day: More
    Started in the 1970. Now established as of 2009 by the United Nations General Assembly. A environmental protection observance.
    From Wikipedia: 'Earth Day is an annual event, celebrated on April 22, on which day events worldwide are held to demonstrate support for environmental protection. It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network, and celebrated in more than 193 countries each year.

    'On Earth Day 2016, the landmark Paris Agreement is scheduled to be signed by the United States, China, and some 120 other countries. This signing satisfies a key requirement for the entry into force of the historic draft climate protection treaty adopted by consensus of the 195 nations present at the 2015 United Nations Climate Change Conference in Paris.

    In 1969 at a UNESCO Conference in San Francisco, peace activist John McConnell proposed a day to honor the Earth and the concept of peace, to first be celebrated on March 21, 1970, the first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a Proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later a separate Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in first held on April 22, 1970. Nelson was later awarded the Presidential Medal of Freedom Award in recognition of his work. While this April 22 Earth Day was focused on the United States, an organization launched by Denis Hayes, who was the original national coordinator in 1970, took it international in 1990 and organized events in 141 nations. Numerous communities celebrate Earth Week, an entire week of activities focused on environmental issues that troubled the world'.

      From Wikipedia: 'Primary immunodeficiencies are disorders in which part of the body's immune system is missing or does not function normally. To be considered a primary immunodeficiency, the cause of the immune deficiency must not be secondary in nature (i.e., caused by other disease, drug treatment, or environmental exposure to toxins). Most primary immunodeficiencies are genetic disorders; the majority are diagnosed in children under the age of one, although milder forms may not be recognized until adulthood. About 1 in 500 people in the United States are born with a primary immunodeficiency.'

      'The precise symptoms of a primary immunodeficiency depend on the type of defect. Generally, the symptoms and signs that lead to the diagnosis of an immunodeficiency include recurrent or persistent infections or developmental delay as a result of infection. Particular organ problems (e.g. diseases involving the skin, heart, facial development and skeletal system) may be present in certain conditions. Others predispose to autoimmune disease, where the immune system attacks the body's own tissues, or tumours (sometimes specific forms of cancer, such as lymphoma). The nature of the infections, as well as the additional features, may provide clues as to the exact nature of the immune defect.

      The treatment of primary immunodeficiencies depends foremost on the nature of the abnormality. This may range from immunoglobulin replacement therapy in antibody deficiencies—in the form of intravenous immunoglobulin (IVIG) or subcutaneous immunoglobulin (SCIG)—to hematopoietic stem cell transplantationf(HSCT)or SCID and other severe immunodeficiences. Reduction of exposure to pathogens may be recommended, and in many situations prophylactic antibiotics may be advised. Virus-specific T-Lymphocytes(VST) therapy is used for patients who have received hematopoietic stem cell transplantation that has proven to be unsuccessful.It is a treatment that has been very useful in prevent and treating viral infections after HSCT. VST therapy uses active donor T-cells that are isolated from alloreactive T-cells (which have proven immunity against one or more viruses) that might cause graft-versus host disease.(GVHD) VST have been produced primarily by ex-vivo cultures and by the expansion of T-lymphocytes after stimulation with viral antigens. This is carried out by using donor-derived antigen- presenting cells.These new methods have reduced culture time to 10-12 days by using specific cytokines from adult donors or virus-naive cord blood.This treatment is far quicker and with a substantially higher success rate than the 3-6 months it takes to carry out HSCT on a patient diagnosed with a primary immunodeficiency'.

    • Oklahoma Day: More
      The date that the 'Oklahoma Lands', now the state of Oklahoma, was opened for settlement.
    • International Mother Earth Day: More
      From Wikipedia: 'International Mother Earth Day was established in 2009, by the General Assembly under Resolution A/RES/63/278. The Resolution was introduced by The Plurinational State of Bolivia and endorsed by over 50 member states. It recognizes that "the Earth and its ecosystems are our home" and that "it is necessary to promote harmony with nature and the Earth." The term Mother Earth is used because it "reflects the interdependence that exists among human beings, other living species and the planet we all inhabit". It is decided to designate April 22 as International Mother Earth Day'.

  • In 1823, R. J. Tyers patented roller skate, the 'Rolito', a five wheeled inline design. The four wheeled skate was patented in 1860 by Reuben Shaler, as the Parlor Skate.
    From Wikipedia: 'The first patented roller skate was introduced in 1760 by Dutch-Belgian inventor John Joseph Merlin. His roller skate wasn't much more than an ice skate with wheels where the blade goes, a style we would call inline today. They were hard to steer and hard to stop because they didn't have brakes and as such were not very popular. The initial "test pilot" of the first prototype of the skate was in the city of Huy, which had a party with Merlin playing the violin.

    'In 1863, James Plimpton from Massachusetts invented the "rocking" skate and used a four-wheel configuration for stability, and independent a xles that turned by pressing to one side of the skate or the other when the skater wants to create an edge. This was a vast improvement on the Merlin design that was easier to use and drove the huge popularity of roller skating, dubbed "rinkomania" in the 1860s and 1870s, which spread to Europe and around the world, and continued through the 1930s. The Plimpton skate is still used today.

    From Wikipedia: 'The Oklahoma Land Rush of 1889 was the first land rush into the Unassigned Lands. The area that was opened to settlement included all or part of the present-day Canadian, Cleveland, Kingfisher, Logan, Oklahoma, and Payne counties of the US state of Oklahoma. The land run started at high noon on April 22, 1889, with an estimated 50,000 people lined up for their piece of the available two million acres (8,000 km˛). The Unassigned Lands were considered some of the best unoccupied public land in the United States. The Indian Appropriations Bill of 1889 was passed and signed into law with an amendment by Illinois Representative William McKendree Springer, that authorized President Benjamin Harrison to open the two million acres (8,000 km˛) for settlement. The authorized President Benjamin Harrison to open the two million acres (8,000 km˛) for settlement. The Homestead Act of 1862, signed by President Abraham Lincoln, allowed legal settlers to claim lots up to 160 acres (0.65 km2) in size. Provided a settler lived on the land and improved it, the settler could then receive the title to the land'.

  • In 1915, The use of poison gas in World War I escalates when chlorine gas is released as a chemical weapon in the Second Battle of Ypres.
    From Wikipedia: 'Chemical weapons were first used in World War I. They were primarily used to demoralize, injure, and kill entrenched defenders, against whom the indiscriminate and generally very slow-moving or static nature of gas clouds would be most effective. The types of weapons employed ranged from disabling chemicals, such as tear gas and the severe mustard gas, to lethal agents like phosgene and chlorine. This chemical warfare was a major component of the capacity of gas was limited, with four percent of combat deaths caused by gas. Gas was unlike most other weapons of the period because it was possible to develop effective countermeasures, such as gas masks. In the later stages of the war, as the use of gas increased, its overall effectiveness diminished. The widespread use of these agents of chemical warfare, and wartime advances in the composition of high explosives, gave rise to an occasionally expressed view of World War I as "the chemists' war".

    The use of poison gas performed by all major belligerents throughout World War I constituted war crimes as its use violated the 1899 Hague Declaration Concerning Asphyxiating Gases and the 1907 Hague Convention on Land Warfare, which prohibited the use of "poison or poisoned weapons" in warfare.'

    'By 22 April 1915, the German Army had 168 tons of chlorine deployed in 5,730 cylinders from Langemark–Poelkapelle, north of Ypres. At 17:30, in a slight easterly breeze, the gas was released, forming a gray-green cloud that drifted across positions held by French Colonial troops from Martinique who broke ranks, abandoning their trenches and creating an 8,000-yard (7 km) gap in the Allied line. However, the German infantry were also wary of the gas and, lacking reinforcements, failed to exploit the break before the 1st Canadian Division and assorted French troops reformed the line in scattered, hastily prepared positions 1,000–3,000 yards (910–2,740 m) apart. The Entente governments quickly claimed the attack was a flagrant violation of international law but Germany argued that the Hague treaty had only banned chemical shells, rather than the use of gas projectors'.

April is:

April origin (from Wikipedia):
'The Romans gave this month the Latin name Aprilis but the derivation of this name is uncertain. The traditional etymology is from the verb aperire, 'to open', in allusion to its being the season when trees and flowers begin to 'open', which is supported by comparison with the modern Greek use of (anoixis) (opening) for spring. Since some of the Roman months were named in honor of divinities, and as April was sacred to the goddess Venus, her Veneralia being held on the first day, it has been suggested that April was the second month of the earliest Roman calendar, before Ianuarius and Februarius were added by King Numa Pompilius about 700 BC. It became the fourth month of the calendar year (the year when twelve months are displayed in order) during the time of the decemvirs about 450 BC, when it also was given 29 days. The 30th day was added during the reform of the calendar undertaken by Julius Caesar in the mid-40s BC, which produced the Julian calendar.'

April 'is commonly associated with the season of spring in parts of the Northern Hemisphere and autumn in parts of the Southern Hemisphere, where it is the seasonal equivalent to October in the Northern Hemisphere and vice versa.'
