March 2 is the 61st day of the year (62nd in leap years) in the Gregorian calendar. There are 304 days remaining until the end of the year.

On this day in 1836, the Republic of Texas declares its independence as in a nation from Mexico.

Formed as a break-away republic from Mexico by the Texas Revolution, the state claimed borders that encompassed an area that included all of the present U.S. state of Texas, as well as parts of present-day New Mexico, Oklahoma, Kansas, Colorado, and Wyoming based upon the Treaties of Velasco between the newly created Texas Republic and Mexico. The eastern boundary with the United States was defined by the Adams-Onís Treaty between the United States and Spain, in 1819. Its southern and western-most boundary with Mexico was under dispute throughout the existence of the Republic, with Texas claiming that the boundary was the Rio Grande, and Mexico claiming the Nueces River as the boundary. This dispute would later become a trigger for the Mexican-American War, after the annexation of Texas by the United States.

Establishment

The Republic of Texas was created from part of the Mexican state Coahuila y Tejas. Mexico was in turmoil as leaders attempted to determine an optimal form of government. In 1835, when President Antonio Lopez de Santa Anna abolished the Constitution of 1824, granting himself enormous powers over the government, wary colonists in Texas began forming Committees of Correspondence and Safety. A central committee in San Felipe de Austin coordinated their activities. In the Mexican interior, several states revolted against the new centralist policies. The Texas Revolution officially began on October 2, 1835, in the Battle of Gonzales. Although the Texians originally fought for the reinstatement of the Constitution of 1824, by 1836 the aim of the war had changed. The Convention of 1836 declared independence on March 2, 1836, and officially formed the Republic of Texas.

March 1 is the 60th day of the year (61st in leap years) in the Gregorian calendar. There are 305 days remaining until the end of the year.

On this day in 1961, President John F. Kennedy issues Executive Order #10924, establishing the Peace Corps as a new agency within the Department of State. The same day, he sent a message to Congress asking for permanent funding for the agency, which would send trained American men and women to foreign nations to assist in development efforts. The Peace Corps captured the imagination of the U.S. public, and during the week after its creation thousands of letters poured into Washington from young Americans hoping to volunteer.

The Peace Corps is an American volunteer program run by the United States Government, as well as a government agency of the same name. The mission of the Peace Corps includes three goals: providing technical assistance, helping people outside the United States to understand U.S. culture, and helping Americans understand the cultures of other countries. Generally, the work is related to social and economic development. Each program participant, (aka Peace Corps Volunteer), is an American citizen, typically with a college degree, who works abroad for a period of 24 months after three months of training. Volunteers work with governments, schools, non-profit organizations, non-government organizations, and entrepreneurs in education, hunger, business, information technology, agriculture, and the environment. After 24 months of service, volunteers can request an extension of service.

Kennedy appointed his brother-in-law Sargent Shriver to be the program’s first director. Shriver fleshed out the organization with the help of Warren Wiggins and others. Shriver and his think tank outlined the organization’s goals and set the initial number of volunteers. The program began recruiting in July, 1962.

Until about 1967, applicants had to pass a placement test that tested “general aptitude” (knowledge of various skills needed for Peace Corps assignments) and language aptitude. After an address from Kennedy, who was introduced by Rev. Russell Fuller of Memorial Christian Church, Disciples of Christ, on August 28, 1961, the first group of volunteers left for Ghana and Tanzania. The program was formally authorized by Congress on September 22, 1961, and within two years over 7,300 volunteers were serving in 44 countries. This number increased to 15,000 in June 1966, the largest number in the organization’s history.

February 28 is the 59th day of the year in the Gregorian calendar. There are 306 days remaining until the end of the year (307 in leap years)

On this day in 1953, Cambridge University scientists James D. Watson and Frances H.C. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes.

History of DNA research

DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it “nuclein”. In 1919, Phoebus Levene identified the base, sugar and phosphate nucleotide unit. Levene suggested that DNA consisted of a string of nucleotide units linked together through the phosphate groups. However, Levene thought the chain was short and the bases repeated in a fixed order. In 1937 William Astbury produced the first X-ray diffraction patterns that showed that DNA had a regular structure.

In 1928, Frederick Griffith discovered that traits of the “smooth” form of the Pneumococcus could be transferred to the “rough” form of the same bacteria by mixing killed “smooth” bacteria with the live “rough” form. This system provided the first clear suggestion that DNA carries genetic information, the Avery-MacLeod-McCarty experiment, when Oswald Avery, along with coworkers Colin MacLeod and Maclyn McCarty, identified DNA as the transforming principle in 1943. DNA’s role in heredity was confirmed in 1952, when Alfred Hershey and Martha Chase in the Hershey-Chase experiment showed that DNA is the genetic material of the T2 phage.

In 1953, James D. Watson and Francis Crick suggested what is now accepted as the first correct double-helix model of DNA structure in the journal Nature. Their double-helix, molecular model of DNA was then based on a single X-ray diffraction image (labeled as “Photo 51”) taken by Rosalind Franklin and Raymond Gosling in May 1952, as well as the information that the DNA bases are paired – also obtained through private communications from Erwin Chargaff in the previous years. Chargaff’s rules played a very important role in establishing double-helix configurations for B-DNA as well as A-DNA.

Experimental evidence supporting the Watson and Crick model were published in a series of five articles in the same issue of Nature. Of these, Franklin and Gosling’s paper was the first publication of their own X-ray diffraction data and original analysis method that partially supported the Watson and Crick model; this issue also contained an article on DNA structure by Maurice Wilkins and two of his colleagues, whose analysis and in vivo B-DNA X-ray patterns also supported the presence in vivo of the double-helical DNA configurations as proposed by Crick and Watson for their double-helix molecular model of DNA in the previous two pages of Nature. In 1962, after Franklin’s death, Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine. However, Nobel rules of the time allowed only living recipients, but a vigorous debate continues on who should receive credit for the discovery.

February 27 is the 58th day of the year in the Gregorian calendar. There are 307 days remaining until the end of the year (308 in leap years).

On this day in 1827, New Orleanians take to the streets for Mardi Gras with groups of masked and costumed students dance through the streets of New Orleans, Louisiana, marking the beginning of the city’s famous Mardi Gras celebrations.

The celebration of Carnival–or the weeks between Twelfth Night on January 6 and Ash Wednesday, the beginning of the Christian period of Lent–spread from Rome across Europe and later to the Americas. Nowhere in the United States is Carnival celebrated as grandly as in New Orleans, famous for its over-the-top parades and parties for Mardi Gras (or Fat Tuesday), the last day of the Carnival season.

History

The celebration of Mardi Gras was brought to Louisiana by early French settlers. The first record of the holiday being celebrated in Louisiana was at the mouth of the Mississippi River in what is now lower Plaquemines Parish, Louisiana, on March 3, 1699. Iberville, Bienville, and their men celebrated it as part of an observance of Catholic practice.

The starting date of festivities in New Orleans is unknown. An account from 1743 notes that the custom of Carnival balls was already established. Processions and wearing of masks in the streets on Mardi Gras took place. They were sometimes prohibited by law, and were quickly renewed whenever such restrictions were lifted or enforcement waned. In 1833 Bernard Xavier de Marigny de Mandeville, a rich plantation owner of French descent, raised money to fund an official Mardi Gras celebration.

James R. Creecy in his book Scenes in the South, and Other Miscellaneous Pieces describes New Orleans Mardi Gras in 1835:

   Shrove Tuesday is a day to be remembered by strangers in New Orleans, for that is the day for fun, frolic, and comic masquerading. All of the mischief of the city is alive and wide awake in active operation. Men and boys, women and girls, bond and free, white and black, yellow and brown, exert themselves to invent and appear in grotesque, quizzical, diabolic, horrible, strange masks, and disguises. Human bodies are seen with heads of beasts and birds, beasts and birds with human heads; demi-beasts, demi-fishes, snakes’ heads and bodies with arms of apes; man-bats from the moon; mermaids; satyrs, beggars, monks, and robbers parade and march on foot, on horseback, in wagons, carts, coaches, cars, etc., in rich confusion, up and down the streets, wildly shouting, singing, laughing, drumming, fiddling, fifeing, and all throwing flour broadcast as they wend their reckless way.

On Mardi Gras of 1857, the Mystick Krewe of Comus held its first parade. Comus is the oldest continuously active Mardi Gras organization. It started a number of continuing traditions. It is considered the first Carnival krewe in the modern sense. According to one historian, “Comus was aggressively English in its celebration of what New Orleans had always considered a French festival. It is hard to think of a clearer assertion than this parade that the lead in the holiday had passed from French-speakers to Anglo-Americans. . . .To a certain extent, Americans ‘Americanized’ New Orleans and its Creoles. To a certain extent, New Orleans ‘creolized’ the Americans. Thus the wonder of Anglo-Americans boasting of how their business prowess helped them construct a more elaborate version of the old Creole Carnival. The lead in organized Carnival passed from Creole to American just as political and economic power did over the course of the nineteenth century. The spectacle of Creole-American Carnival, with Americans using Carnival forms to compete with Creoles in the ballrooms and on the streets, represents the creation of a New Orleans culture neither entirely Creole nor entirely American.”

In 1875 Louisiana declared Mardi Gras a legal state holiday. War, economic, political, and weather conditions sometimes led to cancellation of some or all major parades, especially during the American Civil War, World War I and World War II, but the city has always celebrated Carnival.
