February 28 - The rarest of genetics

 On the last day of February we recognize that not every disease is known as widely as others with "Rare Disease Day".

Created in 2008 for those unknown or overlooked illnesses out there.  And it started as a day on February 29th, itself a rare day and then morphed into just the 'last day of February'.

On this day in 1953 Franklin, Watson and Crick used some Xrays to discover the form of the building blocks of life, DNA.

Exposure 51 shows how the DNA is made up of a double helix.

February 15 - 10 Flag Codes

 Canada's telltale maple leaf was officially adopted on this day in 1965.

The official "National Flag Day of Canada" was declared in 1996.

Also on this day in 2001 in the journal "Nature" the human genome was officially first officially fully mapped and published.

Kind of a cool concept when you think about it, being able to go in and read allele by allele.  21 years later there's so much we can.

It's also on this day in 1971 that the Brits decided to start using 'decimalized' currency.  Meaning that currency was now based on 10s.  

Prior to this a pound was 20 shillings.  Each shilling was 12 pence.  Now a pound is just 100 p (instead of 240).
