The Mexican-American War, lasting from 1846 to 1848, resulted in Mexico having to sign the Treaty of Guadalupe.  Some Democrats actually argued for the total annexation of Mexico, but President Polk argued against that. 

On February 2, 1848, while Mexico City was occupied by United States Troops, the treaty was negotiated by a member of the State Department and Mexican representatives  President Polk had actually already recalled Nicholas Trist, the State Department employee, but he ignored the recall and finisTreaty of Guadalupe Is Signed On February 2, 1848Credit: http://en.wikipedia.org/wiki/File:Mexican_Cession_in_Mexican_View.PNGhed the treaty. 

The treaty gave new land of Mexico to the United States, and made Mexico recognize other territories that was already not under their control.  The Republic of Texas, already independent, was still claimed by the Mexican government.  The size of Mexico dropped by over half, although a lot of the land ceded to the United States was empty at the time.

The origin of Groundhog Day can be found in old European weather tales, however, it was usually a badger or bear.  In America, the tradition continued in the early 1800s, with the predictor of weather being a groundhog.  The first celebration of Groundhog Day in Punxsutawney, Pennsylvania took place on February 2, 1887, and has taken place each year since. 

In Alaska, since there are very few groundhogs, this day is celebrated as Marmot Day, and was officially confirmed by the Alaska Legislature in 2009.  Governor Sarah Palin signed the bill.

The Lancet, a weekly general medical journal, issues a retraction of an article published in 1The Lancet Retracts The Article Linking Autism and the MMR VaccineCredit: http://en.wikipedia.org/wiki/File:Measles_US_1944-2007_inset.png998 that linked the MMR vaccine to autism.  The original article cited largely anecdotal evidence for the claim, and it was later found that the author, Andrew Wakefield had multiple conflicts of interest and was not reliable.  The Lancet partially retracted the article in 2004 and fully in 2010.  Numerous studies have found no link in autism and the vaccine, while the occurrence of measles and mumps in Britain occurred in 2006 at 13 and 37 times greater than 1998 levels.  Andrew Wakefield had his medical license revoked in 2010.
