Sappy cat bonus, Commander Samuel Vimes in repose.
When I sit in the chair of the person he obviously loves best, Sam boxes me about the ears with both front paws and tries to eat my hair. Just last night, in fact.
Today is FLAG DAY, so here are some patriotic kitties.
Flag Day commemorates the adoption of the stars and stripes as the official flag of the United States of America in 1777. Observance of Flag Day came much later. In 1916, Wilson recommended the a day to honor the flag, but Flag Day was not designated as an official holiday until Harry Truman signed an Act of Congress in 1949 proclaiming June 14 as a nation wide observance.
No post on Flag Day would be complete without mentioning Betsy Ross, creator of the original American flag.
This is the Betsy Ross house and museum in Philadelphia.
These beautiful creatures are white tigers. As you can see from the black stripes, these tigers are not albinos. Researchers in in China’s Chimelong Safari Park sequenced the genome of white tigers and their normal colored relatives. They found a variation in just one gene, SLC45A2, that makes the difference, and makes white tigers white:
The SLC45A2 gene makes a protein of the same name, which consists of 560 amino acids. A single mutation in the gene—a change in just one DNA letter—switches one of those 560 amino acids from an alanine to a valine. This distorts the protein’s shape, and potentially prevents it from taking part in the creation of red-yellow melanin. Every white tiger has two copies of this mutated gene, and can only make the distorted protein. That’s all it takes to change their coats from orange to white.
