   DNA Double Helix stores genetic information.     DNA Polymerase replicates DNA.

   RNA Polymerase synthesizes RNA from DNA.   Ribosomes use RNA to build proteins

These four biological molecules are essential to all life on Earth.

They originated more than 3 Billion years ago during the Proterozoic Era, in a common ancestor of Bacteria, Archaea, and Eukaryota.  Together these molecules form the fundamental pattern of the fractal of life; they are specialized machines that replicate each other and produce an endless variety of new forms.  They have evolved over trillions of generations into extraordinarily complex arrangements that consume energy, organize, and reproduce.

January 9, 1806: Horatio Nelson’s state funeral takes place.

Admiral Lord Nelson, regarded as one of Britain’s greatest heroes both during life and even more so after death, lost his arm and sight in one eye in combat while leading forces of the Royal Navy against the Spanish and French navies at the onset of the Napoleonic Wars. He eventually lost his life as well, during his most famous battle and victory at Trafalgar, during which he was wounded. According to Sir Thomas Hardy, the mortally wounded Nelson remarked to him:

Hardy, I do believe they have done it at last… my backbone is shot through.

Nelson was taken below deck and died approximately three hours after being shot, and when news of his death (as well as the Royal Navy’s victory at Trafalgar) reached his country, it seemed almost as though they were unsure how to react. King George III remarked that “We have lost more than we have gained”, and The Times commented that the navy’s “splendid and decisive Victory” had been “dearly purchased” with the life of one of the nation’s most celebrated heroes. Nelson’s funeral procession was grand and befitting someone so highly-regarded by his people; it consisted of thirty-two admirals and 10,000 soldiers, who accompanied Nelson’s coffin to St. Paul’s Cathedral, where he was interred in a sarcophagus originally intended to carry a cardinal. London’s Trafalgar Square was named in commemoration of the 1805 battle, and at its center stands the 169-foot tall monument commemorating Nelson himself - Nelson’s Column.

Doctor Who Colouring-In Packs aren’t just for those who ask their parents for an xBox or books!

They are for those of us with Photoshop or GIMP or Aviary OR CRAYONS(!) as well.

Ok, if you aren’t familiar with the news about Tumblr’s recently introduced terms of service, that title might just seem bizarre. We suggest checking out this link. When you’re done with that…

We luuuuuuuurve coloring books! Especially b/c we can have SO MUCH FUN with them in Photoshop or crayons or GIMP or Aviary (the latter two are free.) Which is apparently what the BBC Doctor Who site intended:

Stuck for stuff to do over the Easter Holidays? Then grab our brand new Colouring In packs! Pick from either the Monster Pack (featuring a selection of your favourite aliens) or choose instead to bring the Doctor, Amy and Rory to life in our special Heroes pack.

Just in case that isn’t enough we’ve just added all our Doctor Who masks, posters, stories, games and much more to the Fun and Games section of the site. So if you need a Doctor Who fix, why not download a few masks and invite some friends around to play Doctor in the House or just relax into the holidays with a great story.

Go forth and color and edit!
