Watch Video: Let it Snow, Let it Snow, Let it Snow -- "Let it Snow" - Only on Google Chrome and Firefox

The Google Let it Snow feature have recently gone viral and thousands of people have searched for the “let it snow” search term that will allow you to see the feature. The Let it snow song originally written by Sammy Cahn and composed by Jule Styne 66 years ago in 1945 probably never had so many people searching for the song at the same time.

"Let it Snow" - Only on Google Chrome and Firefox
 Google have also added a created a button that will allow you to clear your screen once it is frozen up completely. To clear your screen simply click on the “Blue Defrost Button” on the top right side of your screen and the snow effect will disappear.

As far as we can tell the “Let it Snow Google” Surprise is not working in Internet Explorer 9. If you cannot see the “Google Let it Snow feature” you can watch it in Google Chrome or in Firefox. Both the Google Chrome and the Firefox browsers support the Let it Snow feature.

But if you have only Microsoft's Internet Explorer then watch it here below ... Let it Snow, Let it Snow, Let it Snow, Let it Snow .....

9400-year-old Dog's Bone Fragment Found by Graduate student Samuel Belknap III

PORTLAND, Maine — A University of Maine researcher has found a bone fragment from what he says is the oldest-known domesticated dog in the Americas.



Graduate student Samuel Belknap III says he came across the bone while analyzing a dried-out sample of human waste that had been unearthed during an archaeological dig in Texas in the 1970s.

He says a carbon-dating test pegged the age of the bone at 9,400 years old. A DNA analysis confirmed it came from a dog.

He says it appears the dog was used for food because the bone was found deep inside a pile of human excrement and had changed color after passing through the digestive tract.

The paper by Belknap and other researchers has been accepted, pending revisions, for publication in the American Journal of Physical Anthropology.

New Bacteria Found Eating Up Rusty Iron Structure of shipwrecked Titanic

Scientists examining samples of the shipwrecked Titanic have discovered a new type of bacteria threatening to devour the entire iron structure of the ocean liner.



The new species of microscopic bacteria, Halmonas Titanicae from the Halomondaceae family, has been found eating away at the sunken ship, UK's The Sun reports.

The samples were actually taken from the ship in 1991, but new DNA technology has only recently allowed scientists to identify the rust-eating bacteria.

Scientists predict that clumps of rust attached to the ship will eventually disintegrate into a fine powder in the salt water, resulting in a complete collapse of the structure by 2030.

The findings by Dr Henrietta Mann and Bhavleen Kaur from Dalhousie University in Halifax in Canada and researchers from Spain's University of Sevilla were published late last year in the International Journal of Systematic and Evolutionary Microbiology.

"To explain it in human terms, not every type of bacteria has the same taste … the rusticles on Titanic are made from a composition of different microorganisms and there is one particular bacteria which particularly likes eating iron," Dr Mann said.

"In this case, the bacteria helps to decompose the ship."

This discovery confirms reports by divers who have visited the wreck and said that the ship is gradually decaying.

"It has already lasted for 100 years but eventually there will be nothing left but a rust stain on the bottom of the Atlantic to remember this once magnificent ocean liner from," Dr Mann.

"I think (the) Titanic has maybe 15 or 20 years left. I don’t think it will have too much longer than that."

Chairman of the Irish Titanic Historical Society Ed Coghlan said future generations may think it was "a shame" efforts weren't made to preserve the wreckage even though the task itself would "cost an absolute fortune and is probably impossible".

"The Titanic is a very human story from its construction to its sinking and the re-discovery and it will be fascinating to see what happens to the wreck in the coming years," Mr Coghlan said.

"Fortunately it has been photographed extensively and there are wonderful videos and still shots to show us what it looked like underwater so there will always be a record of it."

The Titanic was called an "unsinkable" ship but it sank after hitting an iceberg while on her maiden voyage in 1912, killing more than 1500 passengers and crew.

It lay undiscovered until 1985 when a combined American-French expedition found the historic ship's resting place 530km south east of Newfoundland.
